Through these technical means, the present invention not only improves the assembly accuracy of the balls in the automation process, but also simplifies the assembly process and enhances the stability and reliability of the overall structure.

[0023] Preferably, if Figures 1 to 4 As shown, a sliding portion 101 is provided at the bottom of the slider body 1, and a group of inner raceway holes 102 are respectively provided on the left and right sides of the sliding portion 101. The inner raceway holes 102 are used to accommodate balls and cooperate with the external guide rails. The rolling groove 200 includes an inner groove portion 202 and an outer groove portion 203. The diameter of the inner groove portion 202 is consistent with the diameter of the inner raceway hole 102 and the two are directly connected; the diameter of the outer groove portion 203 is consistent with the diameter of the outer raceway hole 100 and the two are directly connected.

[0024] A sliding portion 101 is provided at the bottom of the slider body 1, and a group of inner raceway holes 102 are respectively provided on the left and right sides of the sliding portion 101, and these inner raceway holes 102 are used to accommodate balls and cooperate with the external guide rail to ensure that the slider runs smoothly on the guide rail.

By ensuring seamless connection between the inner raceway holes 102, the outer raceway holes 100 and the inner groove portion 202, the outer groove portion 203, the balls can move smoothly between the inner and outer raceway holes 100, and can be accurately introduced from the outer raceway hole 100 into the inner raceway hole 102, thereby realizing efficient and precise assembly of the balls.

[0025] Preferably, if Figure 3 , Figure 4 , Figure 8 and Fig. 9 As shown, a liquid storage portion 204 is formed between two rolling grooves 200 on the same side of the oil circuit dividing plate 2, and flow channels 205 for guiding the flow of oil are respectively opened on the upper and lower sides of the inner end of the liquid storage portion 204, and a liquid storage tank 206 connected to the flow channel 205 is provided at the bottom of the inner end of the liquid storage portion 204, and an oil outlet hole 207 is opened at the bottom of the liquid storage tank 206; a diversion groove 210 is provided at the outer end of the liquid storage portion 204, and both ends of the diversion groove 210 are respectively connected to the two rolling grooves 200 on the same side, and the oil outlet hole 207 is located at the center of the diversion groove 210.

[0026] A liquid storage portion 204 is designed between two rolling grooves 200 on the same side of the oil circuit partition plate 2. The liquid storage portion 204 is provided with flow channels 205 for guiding the flow of oil at the upper and lower sides of the inner end. These flow channels 205 are connected to the liquid storage tank 206 of the liquid storage portion 204. The bottom of the liquid storage tank 206 is provided with an oil outlet 207. Through a reasonable oil circuit layout, it is ensured that the oil can efficiently flow into the liquid storage tank 206 and be evenly distributed to each rolling groove 200 through the oil outlet 207.

[0028] A total oil inlet hole 300 is provided on the end cover 3, a total oil inlet passage 209 is provided on the outer end of the oil circuit partition plate 2, and branch oil inlet holes 208 are provided on the left and right sides of the oil circuit partition plate 2, respectively. Through the connection design between the total oil inlet hole 300, the total oil inlet passage 209 and the branch oil inlet holes 208 on both sides, an efficient and uniform oil distribution system is formed. Specifically, the total oil inlet hole 300 receives lubricating oil supplied from the outside, and guides the oil to the inside of the oil circuit partition plate 2 through the total oil inlet passage 209, and then sends the oil into the flow channel 205 through the branch oil inlet holes 208 on both sides, and evenly distributes it to each rolling groove 200. This design ensures that the oil can be quickly and evenly distributed in the entire slider assembly, reduces the resistance and unevenness of the oil flow, and thus significantly improves the lubrication effect.

[0029] It is worth mentioning that the branch oil inlet hole 208 is larger than the size of the flow channel 205, so as to facilitate the delivery of a large flow rate of oil.

[0030] Furthermore, if Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the end cover 3 includes a reverser cover body 301 and a reverse plate 302, the reverse plate 302 is fixed to the outer end of the reverser cover body 301, and the inner end of the reverser cover body 301 is provided with a first positioning groove 303, and the first positioning groove 303 is connected with the oil circuit partition plate 2 by snapping; the outer end of the reverser cover body 301 is provided with a second positioning groove 304, and the second positioning groove 304 is provided with a mounting opening 305, and the mounting opening 305 is located at the outer end of the outer raceway hole 100 and is connected with the outer raceway hole 100; the reverse plate 302 is snapped on the mounting opening 305 of the second positioning groove 304, and the reverse plate 302 cooperates with the reverser cover body 301 and the rolling groove 200 to form a reverse raceway for ball rolling.

The combined design of the reverser cover body 301 and the reverse plate 302 makes the slider assembly more stable during installation, and the snap-fitting connection between the first positioning groove 303 and the oil circuit partition plate 2 is achieved through precise alignment, thereby avoiding the problem of performance degradation caused by position deviation; the outer end of the reverser cover body 301 is provided with a second positioning groove 304, and the second positioning groove 304 is provided with an installation opening 305, and the installation opening 305 is located at the outer raceway hole 100 The outer end is connected to the outer raceway hole 100, and the reverse plate 302 is fixed to the mounting port 305 of the second positioning groove 304 by a snap-fitting manner, ensuring the precise positioning and tight fit between the reverse plate 302 and the reverse device cover 301. At the same time, the reverse plate 302 cooperates with the reverse device cover 301 and the rolling groove 200 to form a reverse raceway for the rolling of the balls. This structural optimization not only realizes the smooth rolling and precise positioning of the balls, but also enhances the overall stability and operation accuracy of the slider. It is worth mentioning that the design of the second positioning groove 304 and the mounting port 305 enables the reverse plate 302 to be firmly installed near the outer raceway hole 100, and through cooperation with the rolling groove 200, it ensures a smooth transition of the balls when entering and leaving the raceway, reduces friction and wear, and extends the service life of the slider.

The first limiting portion 306 is located at the outer end of the rolling groove 200 to limit the position of the ball. The connecting portion 307 is located at the outer end of the outer raceway hole 100 and is fixedly connected to the reverse plate 302 .

[0033] The mounting opening 305 includes a first limiting portion 306 and a connecting portion 307, wherein the first limiting portion 306 is located at the outer end of the rolling groove 200, and is used to limit the position of the ball, ensuring that the ball can maintain a precise path and position when entering and leaving the raceway, and the connecting portion 307 is located at the outer end of the outer raceway hole 100, and is fixedly connected to the reverse plate 302, thereby achieving a stable combination between the reverse plate 302 and the reverser cover body 301, and also ensuring that the ball can smoothly transition between the rolling groove 200 and the outer raceway hole 100.

[0035] The reverse plate 302 is provided with a second limiting portion 308, which is embedded in the connecting portion 307 and works in conjunction with the first limiting portion 306 to ensure accurate positioning and smooth transition of the ball during rolling. The first limiting portion 306 is located at the outer end of the rolling groove 200 and is used to limit the position of the ball to prevent it from deflecting or falling off during movement; the second limiting portion 308 is embedded in the connecting portion 307 to further enhance the control of the ball position. The two together with the rolling groove 200 form a complete reverse rolling track, so that the ball can maintain an accurate path when entering and leaving the rolling track and achieve a smooth transition.

[0036] Furthermore, if Figure 5 , Figure 7 , Fig. 9 and Fig.10 As shown, a limiting groove 309 is provided in the connecting portion 307, and a ball hole 310 with the same diameter as the inner raceway hole 102 is opened at the bottom of the limiting groove 309; a guide portion 311 is provided at the outer end of the limiting groove 309, and a guide groove 312 is correspondingly provided on the second limiting portion 308, and the guide portion 311 is connected to the guide groove 312.
