This invention includes a sliding seat, a support seat, a fixed plate, a tripod, a baffle, a support platform, a lifting platform, a hydraulic slider, a top block, a lead screw, an electric nut column, and a bearing. Based on the bearing size and the distance from the center of the bearing hole to the bottom surface, the height of the lifting platform is first precisely adjusted using a laser rangefinder and an electric nut column. This invention has a simple overall structure. The arc-shaped top of the top block and the laser rangefinder can accurately determine the center position of the bearing, and the bearing top can then be used to stably place the bearing onto the bearing seat, ensuring installation accuracy.

[0024] Example: Figure 1 - Figure 6 As shown, this utility model provides a technical solution for a ball screw bearing installation device, including a device body 1. The upper part of the device body 1 is provided with an installation groove 2. Two movable plates 3 are slidably arranged in the installation groove 2. A first screw 4 is rotatably connected to the upper part of the movable plates 3. An adjusting plate 5 is threaded on the outer side of the first screw 4. A lifting groove 6 is provided on the upper part of the adjusting plate 5. A second screw 7 is rotatably connected to the inner wall of the lifting groove 6. A lifting plate 8 is threaded on the outer side of the second screw 7. A fixing component 9 is provided on the lifting plate 8. A support component is provided on the bottom wall inside the installation groove 2.

[0025] Specifically, the adjusting plate 5 slides on the upper part of the moving plate 3; a vertical rod is fixedly installed on the inner wall of the lifting groove 6, and a vertical hole is opened at the corresponding position of the lifting groove 6 relative to the vertical rod. The vertical rod slides in the cavity of the vertical hole, and the vertical rod and the second screw 7 are located on both sides of the opening 15 respectively.

[0026] like Figure 5 As shown, the fixing component 9 includes a bidirectional screw 901 rotatably connected to one side of the lifting plate 8. Two clamping plates 902 are threaded on the outer side of the bidirectional screw 901 and are arranged in a mirror symmetrical manner. The clamping plates 902 slide on one side of the lifting plate 8.

[0027] Specifically, the double-acting screw 901 has two external threads arranged in a mirror symmetry on its outer side, and the two clamping plates 902 are respectively threaded onto the two external threads in the double-acting screw 901.

[0028] like Figure 4 As shown, a base plate 14 is fixedly installed on one side of the lifting plate 8, and the base plate 14 is located below the clamping plate 902.

[0029] like Figure 1 and Figure 3 As shown, both sides of the movable plate 3 are provided with wire grooves, and wire rods are slidably installed in the wire grooves and fixed to the inner wall of the mounting groove 2.

[0030] like Figure 1 and Figure 6 As shown, the support assembly includes two support plates 12 that slide within the cavity of the mounting groove 2. A V-shaped clamping groove 13 is provided on the upper part of the support plate 12, and a guide screw 10 is placed in the V-shaped clamping groove 13.

[0031] like Figure 5 As shown, the two clamping plates 902 are arranged in a V-shape with each other. A stabilizing rod 11 is fixedly installed on one side of the lifting plate 8. A through-type stabilizing hole is opened at the corresponding position of the clamping plate 902 relative to the stabilizing rod 11.

The double-acting screw 901 drives the two clamping plates 902 to move closer to each other and clamp the bearing or bearing seat. Then, according to the axis position of the guide screw 10, rotate the first screw 4. The first screw 4 drives the adjusting plate 5 to slide laterally on the moving plate 3, thereby adjusting the left and right position of the vertical section of the bearing or bearing seat. Then, according to the axis position of the guide screw 10, rotate the second screw 7. The second screw 7 drives the lifting plate 8 to move up and down along the inner wall of the lifting groove 6, thereby adjusting the height of the vertical section of the bearing or bearing seat and making the axis of the bearing or bearing seat directly aligned with the axis of the guide screw 10. Finally, push the moving plate 3 close to the guide screw 10 and assemble.
