It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 5As shown, the utility model provides a screw tightening device for producing refrigerator compressor parts, including: a support frame 1 and a protective cover 3, a first hole 8 is opened on the left surface of the support frame 1 near the top, a first rotating shaft 10 is installed on the inner surface of the first hole 8 through a first bearing, a mounting seat 16 is fixedly connected to the right end surface of the first rotating shaft 10, an insert block 15 is inserted on the inner surface of the mounting seat 16, a sleeve 19 is fixedly connected to the right end surface of the insert block 15, a second hole 9 is opened on the left surface of the support frame 1 near the center, a second rotating shaft 13 is installed on the inner surface of the second hole 9 through a second bearing, a buckle 4 is symmetrically fixedly connected to the right surface of the support frame 1, a block 20 is symmetrically fixedly connected to the outer surface of the protective cover 3, and a driven Gear 11, the right end face of the second rotating shaft 13 is fixedly connected with the driving gear 12, the outer surfaces of the two clamping blocks 20 are respectively engaged with the inner surfaces of the two buckles 4, the outer surface of the driven gear 11 is meshed with the outer surface of the driving gear 12, the protective cover 3 is movably arranged with the first rotating shaft 10, the left end face of the second rotating shaft 13 is fixedly connected with the connecting block 14, the outer surface of the connecting block 14 is rotatably connected with the handle 2 near the bottom, the inner surface of the mounting seat 16 is matched with the outer surface of the plug block 15, the outer surface of the mounting seat 16 is threaded with a hand screw bolt 17, the outer surface of the plug block 15 is provided with a threaded hole 18, the threaded hole 18 is matched with the hand screw bolt 17, and the position of the protective cover 3 matches the positions of the driven gear 11 and the driving gear 12.

[0024] The effect achieved by the entire embodiment 1 is that when it is necessary to tighten the nut on the screw, the screw is inserted into the sleeve 19, and the screw is limited by the sleeve 19. Then the staff limits the nut with one hand, and then turns the handle 2 with the other hand to make the connecting block 14 rotate along the second rotating shaft 13 in the second hole 9, thereby driving the driving gear 12 to rotate. The driving gear 12 is meshed with the driven gear 11, which will drive the driven gear 11 to rotate, so that the first rotating shaft 10 rotates in the first hole 8, and drives the mounting seat 16 and the sleeve 19 to rotate, so that the screw limited in the sleeve 19 is rotated, so that the nut is rotated and tightened on the screw. The diameter of the driving gear 12 is larger than that of the driven gear 11, so that when the driving gear 12 rotates, the driven gear 11 will rotate at a higher speed. At the same time, due to the ratio of the number of teeth of the gears, the driven gear 11 will generate a higher torque than the driving gear 12, achieving a torque amplification effect, improving the efficiency and convenience of tightening, and at the same time, through the active gear 12 The protective cover 3 arranged on the outside of the gear 12 and the driven gear 11 can protect the driving gear 12 and the driven gear 11, prevent the staff from contacting the rotating gears, reduce the risk of accidental injury, and prevent dust and debris from adhering to the gears to maintain their normal operation. At the same time, the blocks 20 on both sides can be pressed to move them inward, so that the blocks 20 and the buckle 4 are no longer engaged, and the protective cover 3 can be separated from the support frame 1 to maintain the internal gears. When the sleeve 19 needs to be replaced, it can be rotated. Tighten the bolt 17 by hand to disengage the bolt 17 from the threaded hole 18, and then the insert block 15 can be unscrewed from the mounting seat 16, and the sleeve 19 can be replaced. After the replacement is completed, the insert block 15 is inserted into the mounting seat 16. The inner walls of the insert block 15 and the mounting seat 16 are both specially shaped, so that when the insert block 15 is installed, the bolt 17 is aligned with the threaded hole 18, and then the bolt 17 is rotated to insert the bolt 17 into the threaded hole 18, so that the installation of the insert block 15 is completed, thereby facilitating the replacement of the sleeve 19.

[0025] Embodiment 2, as Figure 1-Figure 5 As shown, a U-shaped frame 5 is fixedly connected to the bottom of the support frame 1, a threaded rod 7 is threadedly penetrated through the bottom of the U-shaped frame 5, and a clamping block 6 is rotatably connected to the top of the threaded rod 7.

[0026] The effect achieved by the entire embodiment 2 is that when installing the support frame 1, the U-shaped frame 5 can be inserted along the edge of the workbench, and the threaded rod 7 can be rotated to rotate on the U-shaped frame 5, driving the clamping block 6 to move upward, so that the support frame 1 can be quickly fixed by the cooperation of the clamping block 6 and the U-shaped frame 5, and rubber pads are provided on the inner walls of the clamping block 6 and the U-shaped frame 5, which can increase the fixing effect of the support frame 1. When disassembling, the threaded rod 7 can be rotated in the opposite direction, so that the position of the support frame 1 can be adjusted, thereby improving the applicability of the device.

[0027] Working principle: the U-shaped frame 5 can be inserted along the edge of the workbench, and the threaded rod 7 can be rotated to rotate on the U-shaped frame 5, driving the clamping block 6 to move upward, so that the support frame 1 can be quickly fixed by the clamping block 6 and the U-shaped frame 5. After the fixing is completed, the screw rod is inserted into the sleeve 19, and the screw rod is limited by the sleeve 19. Then the staff limits the nut with one hand, and then turns the handle 2 with the other hand to make the connecting block 14 rotate along the second rotating shaft 13 in the second hole 9, thereby driving the driving gear 12 to rotate. The driving gear 12 is meshed with the driven gear 11, which will drive the driven gear 11 to rotate, so that the first rotating shaft 10 is rotated in the first hole 8, driving the mounting seat 16 and the sleeve 19 to rotate, so that the screw rod limited in the sleeve 19 is rotated, so that the nut is rotated on the screw rod. The gear 12 and the driven gear 11 are moved and tightened, which improves the efficiency and convenience of tightening. At the same time, the protective cover 3 arranged on the outside of the driving gear 12 and the driven gear 11 can protect the driving gear 12 and the driven gear 11, prevent the staff from contacting the rotating gears, and reduce the risk of accidental injury. When the sleeve 19 needs to be replaced, the hand-tightening bolt 17 can be rotated to disengage the hand-tightening bolt 17 from the threaded hole 18, and the plug block 15 can be unscrewed from the mounting seat 16 to replace the sleeve 19. When the replacement is completed, the plug block 15 is inserted into the mounting seat 16. The inner walls of the plug block 15 and the mounting seat 16 are both specially shaped. When the plug block 15 is installed, the hand-tightening bolt 17 is aligned with the threaded hole 18, and then the hand-tightening bolt 17 is rotated to insert the hand-tightening bolt 17 into the threaded hole 18 to complete the installation of the plug block 15, thereby facilitating the replacement of the sleeve 19.
