The second bevel gear 7 is meshed on one side of the first bevel gear 6, and the third bevel gear 8 is meshed on the other side of the first bevel gear 6. The second bevel gear 7 and the third bevel gear 8 are both installed with a threaded rod 9 at one end, and the first bevel gear 6 is installed at both ends. A connecting hole 13 is opened at one end of the threaded rod 9, and a detachable connection is formed between the rotating wheel 5 and the connecting hole 13. The outer side wall of the threaded rod 9 is provided with a threaded sleeve 10, and the top of the threaded sleeve 10 is connected to the connecting rod 3. The bottom end is connected. When in use, one end of the wheel 5 is placed into the inside of the connecting hole 13, so that the wheel 5 and the connecting hole 13 are engaged with each other, and then the wheel 5 is rotated to drive a threaded rod 9 to rotate. Since a first bevel gear 6 is installed at one end of the threaded rod 9, and the two sides of the first bevel gear 6 are respectively meshed with the second bevel gear 7 and the third bevel gear 8, the other two threaded rods 9 are driven to rotate, and then under the limit of the limit groove 11 and the limit block 12, the threaded sleeve 10 is driven to move by driving the threaded rod 9, so the connecting rod 3 and the positioning plate 4 are driven to move, and the air-conditioning compressor bearing is positioned by the connecting rod 3 and the positioning plate 4. When the processing is completed, the wheel 5 is rotated in the opposite direction to drive the connecting rod 3 and the positioning plate 4 to move outward. At this time, the air-conditioning compressor bearing can be removed and the next air-conditioning compressor bearing can be processed.

[0020] The limiting structure includes a limiting groove 11 and a limiting block 12. The limiting groove 11 is opened at the lower part of the base 1. The limiting block 12 is arranged inside the limiting groove 11. The top of the limiting block 12 is connected to the bottom end of the threaded sleeve 10. The inner diameter of the limiting groove 11 is larger than the outer diameter of the limiting block 12. A sliding structure is formed between the limiting groove 11 and the limiting block 12. When in use, the threaded sleeve 10 can be limited when moving by utilizing the mutual cooperation between the limiting groove 11 and the limiting block 12, so that the threaded sleeve 10 is more stable when moving.

[0021] A plurality of plastic heads 14 are arranged on the inner side of the positioning plate 4, and the plurality of plastic heads 14 are distributed at equal intervals. A plurality of plastic sheets 15 are installed on the top of the base 1, and the plurality of plastic sheets 15 can perform dust-proof treatment on the grooves on the base 1. When in use, the use of the plastic heads 14 can play an anti-slip and protective role for the bearings when positioning, and the use of the plastic sheets 15 can prevent some garbage from entering the interior of the base 1 during processing.

[0022] The mounting mechanism includes a fixing seat 16, a mounting groove 17, a connecting block 18, a positioning hole 19 and a fixing pin 20. The fixing seat 16 is mounted on a machine tool. The fixing seat 16 is provided with a mounting groove 17. The mounting groove 17 is provided with a connecting block 18. The top of the connecting block 18 is connected to the bottom of the base 1. A positioning hole 19 is provided between the fixing seat 16 and the connecting block 18. A fixing pin 20 is provided inside the positioning hole 19. The inner diameter of the positioning hole 19 is greater than the outer diameter of the fixing pin 20. The positioning hole 19 and the fixing pin 20 form a snap-fit ​​structure. When in use, the clamp is taken out, and then the connecting block 18 at the bottom of the base 1 is placed into the inside of the installation groove 17. When the fixing seat 16 and the connecting block 18 are snapped with each other, the fixing pin 20 is inserted into the inside of the positioning hole 19, and the fixing seat 16 and the connecting block 18 are positioned to complete the convenient installation of the clamp, making the clamp more convenient and efficient during installation and disassembly, so it is more efficient to clean the clamp, thereby greatly improving the convenience of the clamp when in use.

[0023] Working principle: The staff first takes out the fixture, and then places the connecting block 18 at the bottom of the base 1 into the inside of the installation groove 17. When the fixing seat 16 and the connecting block 18 are engaged with each other, the fixing pin 20 is inserted into the inside of the positioning hole 19, and the fixing seat 16 and the connecting block 18 are positioned. Then, the air-conditioning compressor bearing to be processed is placed on the top of the placement plate 2, and then one end of the rotating wheel 5 is placed into the inside of the connecting hole 13, so that the rotating wheel 5 and the connecting hole 13 are engaged with each other, and then the rotating wheel 5 is rotated to drive a threaded rod 9 to rotate. Since a first bevel gear 6 is installed at one end of the threaded rod 9, and the two sides of the first bevel gear 6 are respectively connected to the second bevel gear 7 and the third bevel gear 8. The gears 8 mesh with each other, thereby driving the other two threaded rods 9 to rotate, and then under the limitation of the limit groove 11 and the limit block 12, the threaded rod 9 is used to drive the threaded sleeve 10 to move, thereby driving the connecting rod 3 and the positioning plate 4 to move, and the connecting rod 3 and the positioning plate 4 are used to position the air-conditioning compressor bearing. At the same time, the use of the plastic head 14 can play an anti-slip and protective role for the bearing when positioning, and the use of the plastic sheet 15 can prevent some garbage from entering the interior of the base 1 during processing. When the processing is completed, the rotating wheel 5 is rotated in the opposite direction to drive the connecting rod 3 and the positioning plate 4 to move outward. At this time, the air-conditioning compressor bearing can be removed and the next air-conditioning compressor bearing can be processed.
