[0029] The specific usage and function of this embodiment are as follows:
[0030] In this utility model, when... Figure 1 As shown, when the bracket body 1 is installed on the external machine, the bracket body 1 is placed in the reserved installation position on the external machine, and the fixed bearing frame 8 is installed on the external machine with bolts, as shown. Figure 4 As shown, the bottom of the bracket body 1 is a section with a reserved installation position for external machines. At this time, the anti-loosening locking pin 5 is inserted into the through hole of the bearing locking pin 4, as shown in the figure. Figure 2 As shown, the anti-loosening anti-rotation post 5 is used to prevent the bearing locking post 4 from rotating and loosening. At the same time, the locking post 6 is adjusted to be in the locked state, and the locking post 6 is adjusted to press firmly against the fixed bearing frame 8, as shown in the figure. Figure 5As shown, this prevents the load-bearing adjustment block 2 from moving left or right. When the load-bearing adjustment block 2 moves left or right, the tool rotates the adjusting locking pin 6 to engage with the threaded connection of the load-bearing adjustment block 2, causing the adjusting locking pin 6 to loosen its pressure on the fixed load-bearing frame 8. This releases the locking pin 6 from locking the load-bearing adjustment block 2. Then, the tool rotates the position adjusting rod 7 to engage with the threaded connection of the fixed load-bearing frame 8, causing the position adjusting rod 7 to move left or right through the threaded connection. This causes the position adjusting rod 7 to drive the load-bearing adjustment block 2 to move left or right synchronously through the bearing. The load-bearing adjustment block 2 then drives the supported bearing 3 to move left or right synchronously, thus achieving adjustment and compensation for errors. After adjustment, the tool rotates the adjusting locking pin 6 to engage with the threaded connection of the load-bearing adjustment block 2, causing the adjusting locking pin 6 to move inward through the threaded connection, pressing the adjusting locking pin 6 against the fixed load-bearing frame 8. This locks the adjusted load-bearing adjustment block 2 with the adjusting locking pin 6, preventing displacement of the load-bearing adjustment block 2 during use.
[0031] Example 2:
[0032] The difference from Embodiment 1 is that the regular hexagonal groove of the anti-loosening anti-rotation post 5 can also be set as a regular heptagonal groove, so that the anti-loosening anti-rotation post 5 can only be rotated by a special tool that cooperates with the regular heptagonal groove, thus preventing non-workers from rotating and disassembling the anti-loosening anti-rotation post 5.
[0033] Example 3:
[0034] The difference from Embodiment 1 is that the regular hexagonal prism of the adjusting locking pin 6 can also be set as a regular heptagonal prism, thereby requiring a special tool that works with the regular heptagonal prism to rotate the adjusting locking pin 6, preventing non-staff members from rotating or disassembling the adjusting locking pin 6.
