[0072] After the end cover 100 is positioned on the base 210, the first positioning column 500 is driven by the hydraulic cylinder to lift and lower the end cover 100. After the end cover 100 is positioned, the guide shoe seat 110 is placed on the end cover 100. The guide shoe seat 110 and the end cover 100 are pre-fixed by bolt fasteners. Then, the second positioning column 310 is controlled by the driving cylinder 330 to extend downward from the mounting bracket 340. The driving cylinder 330 is connected between the mounting bracket 340 and the mounting plate 320. The mounting plate 320 is controlled to move by the driving cylinder 330 so that the second positioning column 310 moves at the same time, which has high structural accuracy. Then, the mounting bracket 340 and the second positioning column 310 are controlled to move downward by the lifting mechanism 400.

[0073] Example 3:

[0074] like Figure 3-Figure 7 As shown, the embodiment of the present application provides a process for installing a thrust pad 120 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] The rotation mechanism 380 is 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 to 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 through the positioning mechanism 370. After the 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. After 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;

[0083] A drive plate 362 is movably mounted on the mounting frame 340;

[0084] A first driving motor 363 is used to drive the driving disk 362 to rotate;

[0085] The driving disc 362 is connected to the first driving motor 363 via a gear. The driving disc 362 is provided with a sliding groove 364 . The limiting seat 361 is provided with a sliding portion 365 corresponding to the sliding groove 364 .

[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 by 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. 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 limit seat 361 contracts, the thrust pad 120 can be pushed into the mounting hole of the guide pad seat 110.

[0090] The first electromagnet 373 is respectively placed on the positioning block 371 and the limiting seat 361 and corresponds to each other.

[0091] The positioning block 371 is movably mounted on the limiting seat 361. When the thrust pad 120 is placed on the limiting seat 361, the thrust pad 120 is rotated so that the positioning hole on the thrust pad 120 corresponds 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. When the limiting seat 361 extends out of the placement hole 341, the axis of the positioning block 371 corresponds to the axis of the positioning pin 140.

[0096] The driving seat 381 is Y-shaped, and the placement hole 341 is provided with a driving groove 342 corresponding to the driving wheel 382 .

[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, so that the driving wheel 382 is offset from the thrust pad 120. The driving wheel 382 is controlled to rotate by the second driving motor 384, thereby realizing the rotation adjustment of the thrust pad 120 in the placement hole 341. The driving seat 381 is Y-shaped and passes through the two driving wheels 382 at the end. The driving seat 381 is provided with 2-3 evenly distributed around the axis, which further improves the stability of the thrust pad 120 during rotation, and facilitates the extension and retraction of the driving wheel 382 through the driving groove 342.

[0098] Example 4:

[0099] like Figure 4 As shown, the embodiment of the present application provides a process for installing a thrust pad 120 of a guide thrust sliding bearing. In addition to the above technical features, the locking mechanism 390 further includes:

[0100] The third electromagnets are respectively placed between the mounting bracket 340 and the mounting base 350 and correspond to each other.

[0101] After the second positioning column 310 on the mounting frame 340 completes positioning, the mounting frame 340 and the mounting seat 350 are locked by the third electromagnet, thereby improving the stability during locking, ensuring the accuracy of the placement hole 341 on the second mounting frame 340 and the mounting hole on the guide shoe seat 110, and further improving the installation accuracy of the thrust shoe 120.

In addition to the above-mentioned technical features, the second positioning column 310 and the push block 311 are further provided with corresponding fourth electromagnets 312.

[0104] The second positioning column 310 corresponds to the diameter size of the mounting hole on the guide shoe seat 110, and the push block 311 corresponds to the diameter size of the placement hole 341. 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.
