When necessary, pre-pressure can be applied to improve the rigidity. At the same time, this design can be used during installation. Due to the elastic deformation of the rolling steel balls and the transfer of contact points, even if the installation surface has some deviations, it can be absorbed by the inside of the slider, resulting in the effect of automatic self-aligning ability and obtaining high-precision, stable and smooth motion.

[0004] However, the prior art CN218953833U patent needs to install the slide rail during use. The prior art is not convenient for assembling the ball linear slide rail, the installation is complicated, the work efficiency is reduced, and the practicality is low. Utility Model Content

[0025] The main mechanism 1 also includes a connecting plate 104, a telescopic rod 105, a return spring 106, a clamping block 107 and a clamping groove 108. The connecting plate 104 is fixedly mounted on the lower end of the slide rail body 102, the telescopic rod 105 is fixedly mounted on the left and right ends of the inner end of the connecting plate 104, the return spring 106 is movably mounted on the outer end of the telescopic rod 105, the clamping block 107 is fixedly mounted on the end of the telescopic rod 105, and the clamping groove 108 is fixedly arranged on the left and right ends of the inner end of the connecting groove 103. 108 is adapted to the clamping block 107. The staff inserts the connecting plate 104 at the lower end of the slide rail body 102 into the connecting groove 103 of the mounting base 101. During the insertion process, an extrusion force is generated on the clamping block 107 and the telescopic rod 105, causing them to retract into the connecting plate 104. When the clamping block 107 is aligned with the clamping groove 108, the extrusion force disappears, and the reset spring 106 drives the telescopic rod 105 and the clamping block 107 to return to their original positions. At this time, the clamping block 107 is clamped into the clamping groove 108 to complete the assembly.

[0026] The auxiliary mechanism 2 includes a mounting plate 201, a reducer 202, a motor 203, a screw rod 204, a slider 205, a positioning groove 206, a ball body 207, a fixing plate 208 and a bolt 209. The mounting plate 201 is fixedly mounted on the front and rear ends of the slide rail body 102, the reducer 202 is fixedly mounted on the rear end of the mounting plate 201, the transmission end of the reducer 202 extends to the middle of the mounting plate 201, the motor 203 is fixedly mounted on the rear end of the reducer 202, the screw rod 204 is fixedly mounted on the front end of the transmission end of the reducer 202, the screw rod 204 is located in the middle of the mounting plate 201, the screw rod 204 is movably connected to the mounting plate 201, the slider 205 is threadedly mounted on the outer end of the screw rod 204, the slider 205 is located at the upper end of the slide rail body 102, the slider 205 is movably connected to the slide rail body 102, and the positioning groove 206 is fixedly arranged on the left and right ends of the slide rail body 102 The ball body 207 is movably mounted on the inner end of the slider 205, and the ball body 207 extends to the inner end of the positioning groove 206. The ball body 207 is movably connected to the positioning groove 206. The fixing plate 208 is fixedly mounted on the front and rear ends of the mounting plate 201. The fixing plate 208 is located at the front and rear ends of the mounting base 101. The fixing plate 208 is movably connected to the mounting base 101. The bolts 209 are threadedly mounted on the front and rear ends of the fixing plate 208, and the bolts 209 extend to the inner end of the mounting base 101. The motor 203 reduces the rotation speed through the reducer 202 to drive the screw rod 204 to rotate slowly. The screw rod 204 drives the slider 205 to move slowly on the slide rail body 102. When the slider 205 moves, it will drive the ball body 207 to rotate in the positioning groove 206. The ball body 207 improves the stability of the movement of the slider 205 and reduces the friction with the slide rail body 102.

[0027] Working principle: First, when using the ball linear guide rail that is easy to assemble, the staff inserts the connecting plate 104 at the lower end of the guide rail body 102 into the connecting groove 103 of the mounting base 101. During the insertion process, an extrusion force is generated on the clamping block 107 and the telescopic rod 105, causing them to retract into the connecting plate 104. When the clamping block 107 is aligned with the clamping groove 108, the extrusion force disappears, and the return spring 106 drives the telescopic rod 105 and the clamping block 107 to return to their original positions. At this time, the clamping block 107 is clamped into the clamping groove 108 to complete the assembly, and then the staff passes The front and rear ends of the slide rail body 102 and the mounting base 101 are reinforced by fixing plates 208 and bolts 209 to further improve the firmness of the connection. Then the motor 203 reduces the rotation speed through the reducer 202 to drive the screw rod 204 to rotate slowly. The screw rod 204 drives the slider 205 to move slowly on the slide rail body 102. When the slider 205 moves, it drives the ball body 207 to rotate in the positioning groove 206. The ball body 207 improves the stability of the movement of the slider 205 and reduces the friction with the slide rail body 102.
