Linear guide applications:
1, linear guide is mainly used in the automation machinery more, like the German imports of machine tools, paper bowl machine, laser welding machine, etc., of course, linear guide and linear shaft is used.
2, linear guide is mainly used in the relatively high precision mechanical structure, the linear guide between the moving components and fixed elements between the medium without the use of rolling steel ball. Because the rolling ball to adapt to high-speed movement, the friction coefficient is small, Linear Rail high sensitivity to meet the working parts of the work requirements, such as machine tool turret, pallet and so on. If the force acting on the ball is too large, the ball is subjected to the preloading time for too long, Linear Rail resulting in an increase in the movement resistance of the stent.
Straight rails are precision parts, and therefore require considerable caution when used, even with high-performance linear guides, which can not be expected to achieve the desired performance and easy to damage the linear guide if used improperly. Therefore, the use of linear guide should pay attention to the following:
To prevent corrosion
Direct access to the linear guide by hand, to fully wash away the sweat on hand, Linear Rail and coated with high-quality mineral oil and then operate in the rainy season and summer, especially to pay attention to rust.
Keep the environment clean
Keep the linear guide and its surroundings clean even if the tiny dust can not be seen by the naked eye into the rail, will increase the wear, vibration and noise of the guide rail.
Installation should be careful and careful
Linear guide in the use of the installation should be careful and careful, Linear Rail does not allow strong stamping, do not allow the hammer directly hit the rail, does not allow the transfer of pressure through the rolling body.
The installation tool should be appropriate
Linear Guides Use suitable and accurate installation tools to use special tools as much as possible to avoid the use of cloth and short fibers and the like.
Rails, linear shafts as one of the core components of the device, its function is to guide and support the role. In order to ensure that the machine has a higher processing accuracy, requiring its rails, Linear Rail straight line with a high degree of guidance accuracy and good sport stability. During the operation of the equipment, due to the processing of the workpiece will produce a lot of corrosive dust and smoke, the base of these fumes and dust long-term deposition in a large number of rails, linear shaft surface, the equipment processing accuracy has a great impact, Linear Rail and will The formation of corrosion points on the surface of the linear axis of the guide rails, shortening the service life of the equipment. In order to make the machine normal and stable work to ensure that the quality of processing products, Linear Rail to do a good job of rails, linear shaft routine maintenance. Note: Clean the guide rail please prepare - dry cotton, lubricating oil. Engraving machine rails are divided into linear guide, roller guide. Clean the linear guide: first move the laser head to the far right (or left), find the linear guide, wipe with a dry cotton until the bright and clean, plus a little oil (sewing oil can be used, do not use oil) , The laser head slowly push around several times, Linear Rail so that even the distribution of lubricants can be. Roller guide cleaning: the beam to move to the inside, open the machine on both sides of the end of the cover, find the rails, with a dry cotton cloth on both sides of the guide rail and roller contact place to wipe clean, and then move the beam, the remaining clean place.
Linear guide action and working principle
The slider is a mold assembly capable of sliding in a direction perpendicular to the opening and closing direction or at an angle to the opening and closing mode in the mold opening operation of the mold. Linear Rail When the product structure makes the mold in the absence of the slider can not be normal stripping the case you have to use the slider. The material itself has the appropriate hardness, wear resistance, enough to withstand the friction of movement. The cavity portion of the slider or the core portion has the same hardness as the other parts of the mold cavity.
Definition: Linear guide, also known as rail, slide, linear guide, linear slide, for linear reciprocating sports occasions, and can take a certain torque, Linear Rail high load can be achieved in the case of high precision linear motion. In the mainland, said linear guide, Taiwan is generally called linear guide, linear slide.
Category: divided into square ball linear guide, double-axis roller linear guide, single-axis linear guide.
Role: linear guide movement is used to support and guide the moving parts, according to a given direction to do reciprocating linear motion. Depending on the nature of the friction, Linear Rail the linear motion guide can be divided into sliding friction rails, rolling friction rails, elastic friction rails, fluid friction rails and other types. Linear bearings are mainly used in the automation machinery, as imported from Germany, machine tools, bending machines, laser welding machines, etc., of course, linear bearings and linear shaft is supporting the use. Like a linear guide is mainly used in the relatively high precision mechanical structure, the linear guide between the moving element and the fixed element between the medium without the use of rolling steel ball.
The DF (45- ° 45) ° combination from the arc trenches can be absorbed by the inside of the rail slider even when the mounting surface is somewhat offset by the elastic deformation of the ball and the transfer of the contact point during installation, Resulting in the effect of self-aligning ability to get high-precision stable smooth motion.
Due to strict control of manufacturing precision, linear guide rail dimensions can be maintained at a certain level, and the slider has a cage designed to prevent the ball off, Linear Rail so some of the series of precision with interchangeability, the customer may need to order rails or Slider, can also be stored separately rails and sliders to reduce storage space.
All directions are highly rigid
The use of four-row circular groove, with four rows of steel balls and other 45 degrees of contact angle, so that the ball to achieve the ideal two-point contact structure, can withstand from the upper and lower and left and right direction of the load; if necessary, Linear Rail can apply preload to improve rigidity.
Can be understood as a rolling guide, is the ball in the slider with the track between the infinite rolling cycle, so that the load platform along the guide rail easily high-precision linear motion, and the friction coefficient down to the conventional sliding guide One fifth, can easily achieve a high positioning accuracy. Slide and guide rail between the end of the unit design, so that the linear guide at the same time to withstand the upper and lower left and other aspects of the load, patented reflow system and streamlined structure design to HIWIN linear guide has a more smooth and low noise movement.
Slider - Moves the movement from a curve to a straight line. Linear Rail The new rail system allows the machine to obtain rapid traverse speed, in the case of the same spindle speed, rapid feed is a linear guide characteristics. The linear guide, like the planar guide, has two basic elements; one is a fixed element and the other is a moving element. As the linear guide is a standard component, the machine tool factory. The only thing to do is to process the parallelism of a mounting rail and a calibration guide. Of course, in order to ensure the accuracy of the machine, the bed or column a small amount of scraping research is essential, in most cases, the installation is relatively simple. As a guide rail for the hardened steel, after grinding placed on the installation plane. Compared with the plane guide, the linear guide cross-section of the geometric shape, more complex than the flat guide, the reason is because the guide rails need to be processed out of the groove to facilitate the sliding element movement, groove shape and quantity, depending on the machine to complete Function. For example: a not only bear the linear force, but also to withstand the subversion of the rail system, and only bear the linear force compared to the guide. The design is very different.
Linear guide system of the fixed element (rail) the basic function of the bearing ring, the installation of steel ball bracket, the shape of "v" shape. Linear Rail The brackets wrap the top and sides of the guide rails. In order to support the working parts of the machine, a set of linear guides has at least four brackets. Used to support large parts of the work, the number of stents can be more than four.
