[0073] Embodiment 3:

[0074] like Figure 3-Figure 7 As shown, the embodiment of the present application provides a thrust pad 120 installation process of a guide thrust sliding bearing. In addition to the above technical features, the installation mechanism 300 further includes:

[0075] The mounting seat 350 is movably connected to the mounting frame 340;

[0076] The limiting mechanism 360 corresponds to the placement hole 341 and is placed on the lower side of the mounting frame 340;

[0077] The positioning mechanism 370 is installed on the limiting mechanism 360;

[0078] A rotating mechanism 380, used to control the rotation of the thrust pad 120;

[0079] The locking mechanism 390 is disposed between the mounting seat 350 and the mounting frame 340 .

[0080] The mounting seat 350 is used to connect with the lifting mechanism 400. The mounting seat 350 is movably connected with the mounting frame 340, so that the mounting frame 340 and the second positioning column 310 can be rotated and adjusted to correspond to the mounting hole on the guide shoe seat 110. After the disc spring 130 and the thrust shoe 120 are placed in the placement hole 341, they are first restricted in the placement hole 341 by the limiting mechanism 360, and then the rotating mechanism 380 rotates the thrust shoe 120 placed in the placement hole 341, and the positioning hole on the thrust shoe 120 is aligned with the positioning pin 140 by the positioning mechanism 370. After positioning is completed, the limiting mechanism 360 releases the restriction on the thrust pad 120, and the thrust pad 120 is installed on the guide pad seat 110 by the push block 311 acting on the thrust pad 120. When the second positioning column 310 and the guide pad seat 110 complete the positioning, the mounting seat 350 and the mounting frame 340 are locked by the locking mechanism 390 to ensure that the axis of the placement hole 341 on the mounting frame 340 is always the same as the axis of the mounting hole on the guide pad seat 110 during the lifting process of the mounting seat 350, thereby further improving the installation accuracy of the thrust pad 120.

[0081] Furthermore, the limiting mechanism 360 includes:

[0082] The limiting seat 361 is movably mounted on the mounting frame 340;

[0086] The driving disk 362 is driven to rotate by the first driving motor 363, and the driving disk 362 and the limit seat 361 are movably connected through the sliding groove 364 and the sliding part 365. When the driving disk 362 rotates, the limit seat 361 moves radially along the placement hole 341 on the mounting frame 340, and when the limit seat 361 extends into the placement hole 341, it is used to limit the thrust pad 120 in the placement hole 341.

When the thrust pad 120 is placed on the limiting seat 361, the thrust pad 120 is rotated to make the positioning hole on the thrust pad 120 correspond to the positioning block 371. Under the action of the first spring 372, the positioning block 371 is inserted into the positioning hole on the thrust pad 120. After positioning is completed, the first electromagnet 373 and the second electromagnet 383 are used to control the contraction of the positioning block 371 to facilitate the contraction of the limiting seat 361.

[0097] One of the driving wheels 382 is driven to rotate by the second driving motor. When the thrust pad 120 is placed in the placement hole 341, the driving seat 381 is pushed by the second electromagnet 383 to make the driving wheel 382 and the thrust pad 120 collide. The driving wheel 382 is controlled to rotate by the second driving motor 384, so that the thrust pad 120 can be rotated and adjusted in the placement hole 341. The driving seat 381 is Y-shaped and has two driving wheels 382 at the end. The driving seat 381 is provided with 2-3 driving wheels evenly distributed around the axis, which further improves the stability of the thrust pad 120 during rotation.

The push block 311 is used to improve the stability of the second positioning column 310 during movement. When the second positioning column 310 completes positioning, the second positioning column 310 and the push block 311 are locked by the fourth electromagnet 312 when the second positioning column 310 moves upward.
