Small Knowledge Of Linear Guide Installation (2)

Installation of the reference side rail

Method using false datum

Use the reference surface set near the slide rail mounting part on the bed to find the straightness of the slide rail from the shaft end. However, in this case, it is necessary to fasten the two sliders to the measurement plate.

method with straight line

After the assembly screws are informally locked (as shown in Figure 1.11.20 on the right, so the linear block gauge is used as the reference, start from one end of the slide rail and pass the dial indicator to find out the straightness of the reference plane on the side of the slide rail, while formally locking it. Assembly screws. The installation method of the passive side rail is the same as the method in item 2 on the previous page.

Mounting chip height and chamfer

When installing the linear slide rail, it is necessary to pay attention to whether the condition of the mounting surface chip is appropriate. If the chamfer is too large, the convex part will easily cause poor accuracy of the linear slide rail, and if the height is too high, it will interfere with the slide block. If it can be installed according to the recommended requirements Chips, poor installation accuracy can be ruled out.

Good lubrication is necessary when using a straight line gun. If it is used without oil, the friction of the moving parts will increase, which may be the main reason for shortening the life.

Lubricants are used as follows

(1) Reduce the friction of each moving part to prevent temperature rise and reduce wear

(2) An oil film is formed on the wave surface to ease the surface stress and prolong the rolling fatigue life

(3) Cover the golden black surface with oil film to prevent rust

In addition, even if the straight-shaft linkage is equipped with a gasket, the internal lubricating oil will seep out little by little during the continuous running process, so it is necessary to carry out oiling at an appropriate time interval according to the operating conditions.

Types of Lubricants

The lubricating agent of the linear motion system mainly includes grease and sliding surface oil. The performance of the lubricant usually has the following requirements

(1) The strength of the oil film is high.

(5) No corruption

(2) The friction is small.

6) Excellent anti-embroidery

(3) Excellent wear resistance.

(7) Less powder and water.

4) Excellent thermal stability.

(8) Even with repeated stirring, the consistency of the grease will not change too much.
