Description

Technical Field

[0001] The utility model relates to the technical field of compressor processing, in particular to a clamp for processing a compressor rear cover. Background Art

[0002] The compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it through the motor, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe. The rear cover is a crucial and complex part of the automotive air-conditioning compressor. Due to the great difference in appearance of different rear covers, the internal processing dimensions are also very different.

[0003] Announcement No. "CN216608003U" provides a clamp for processing the U-shaped groove of the rear cover of the compressor, including a bottom plate and a positioning plate, the positioning plate is installed on the bottom plate, and a number of telescopic cylinders are installed on the bottom plate around the positioning plate. The telescopic cylinder is provided with a telescopic shaft that can be telescoped in the vertical direction, and the telescopic shaft is connected to a pressure plate. The pressure plate is close to one side of the positioning plate and is provided with a pressure head above the positioning plate. The device is provided with a positioning plate, a telescopic cylinder and a pressure plate. When in use, the rear cover is placed on the positioning plate for positioning. The telescopic cylinder drives the pressure plate to descend through the telescopic shaft, and the pressure head presses the top of the rear cover to achieve clamping and positioning of the rear cover, ensuring that the rear cover does not deflect in the circumferential direction during processing;

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] Embodiment 1:

[0027] A clamp for processing a compressor rear cover 1, comprising a rear cover 1, a base 2 and a positioning plate 3, wherein the positioning plate 3 is fixedly arranged on the top of the base 2, and five positioning rods 4 are arranged on the positioning plate 3 through an adjustment mechanism, and the tops of the five positioning rods 4 extend into the through holes of the rear cover 1, a driving mechanism is arranged inside the base 2, and the driving mechanism is connected to the adjustment mechanism, and an auxiliary positioning mechanism is arranged on the base 2, and the auxiliary positioning mechanism is connected to the adjustment mechanism;

[0028] The adjusting mechanism includes a driving disk 5, a slide groove 6, a main shaft 7 and a connecting arm 8. The slide groove 6 is arranged on the surface of the positioning disk 3. The positioning rod 4 is slidably arranged in the slide groove 6. The bottom of the positioning rod 4 is fixed to the surface of the connecting arm 8. One end of the connecting arm 8 is hinged to the surface of the driving disk 5. The driving disk 5 is rotatably arranged at the bottom of the positioning disk 3 through the main shaft 7.

[0029] See also Figure 1 , 2 And 3, the main shaft 7 can drive the driving disk 5 to rotate, and the driving disk 5 can drive one end of the connecting arm 8 to rotate synchronously when rotating. Since the overall length of the connecting arm 8 does not change, when the end of the connecting arm 8 that contacts the driving disk 5 is close to the slide groove 6, the other end of the connecting arm 8 can push the positioning rod 4 to translate in the slide groove 6, so that the distance from the center of the positioning rod 4 to the center of the positioning disk 3 can be adjusted, and different sizes of back covers 1 can be adapted within a certain range.

[0030] The driving mechanism includes a motor 9 and a driving shaft 10. The motor 9 is installed in the base 2. The driving shaft 10 rotates in the base 2 and is connected to the output end of the motor 9. The driving shaft 10 is connected to the main shaft 7 through a clutch assembly. The auxiliary positioning mechanism includes a guide rod 11, a connecting plate 12, a traction seat 13 and a threaded rod 14. The threaded rod 14 is rotatably arranged on the base 2. The traction seat 13 is threadedly connected to the threaded rod 14 through a limiter. One end of the connecting plate 12 is horizontally fixed to the top of the traction seat 13, the top of the guide rod 11 is vertically fixed to the other end of the connecting plate 12, and the bottom end of the guide rod 11 is in contact with the surface of the rear cover 1. The threaded rod 14 and the driving shaft 10 are connected through a transmission member. The transmission member is a synchronous wheel 15 fixed to the surface of the driving shaft 10 and the threaded rod 14, and a synchronous belt 16 connecting the two synchronous wheels 15. The limiter includes a movable rod 17 fixed to the side of the traction seat 13, and a vertical rod 18 fixed to the base 2. The movable rod 17 is slidably arranged on the vertical rod 18.

[0031] See also Figure 1 and 2 When the driving shaft 10 rotates, it can drive the threaded rod 14 to rotate synchronously through the synchronous wheel 15 and the synchronous belt 16. When the threaded rod 14 rotates, it can drive the traction seat 13 to have a tendency to rotate synchronously. However, since the movable rod 17 and the vertical rod 18 can limit the traction seat 13 circumferentially, the traction seat 13 cannot rotate synchronously with the threaded rod 14, but will move vertically on the threaded rod 14, so that the traction seat 13 can drive the guide rod 11 to move synchronously through the connecting plate 12, thereby realizing the extrusion and fixation of the rear cover 1 by the guide rod 11.

[0032] The clutch assembly includes a receiving groove 19, a clamping groove 20, a clamping block 21 and a spring 22. The clamping groove 20 is arranged on the surface of the main shaft 7, the receiving groove 19 is arranged on the inner wall of the driving shaft 10, the clamping block 21 is slidably arranged in the receiving groove 19, and one side of the clamping block 21 extends into the clamping groove 20, and the spring 22 is fixed between the clamping block 21 and the receiving groove 19.

[0033] See also Figure 5 When the motor 9 drives the driving shaft 10 to rotate, the driving shaft 10 can drive the main shaft 7 to rotate synchronously through the block 21 and the slot 20. At this time, the main shaft 7 can adjust the positions of the five positioning rods 4 in the slide slot 6 when rotating. Then turn off the motor 9, place the rear cover 1 on the top of the positioning rod 4, so that the top of the positioning rod 4 extends into the through hole of the rear cover 1, and restart the motor 9. Since the position of the positioning rod 4 is limited by the rear cover 1 and cannot move in the slide slot 6, the driving shaft 10 is constantly rotating. Therefore, when the driving shaft 10 drives the block 21 to rotate, it will be squeezed by the slot 20 and the main shaft 7, so that the block 21 squeezes the spring 22 inside the accommodating slot 19, and the main shaft 7 cannot continue to rotate, but the driving shaft 10 can continue to rotate. The driving shaft 10 can drive the threaded rod 14 to rotate through the synchronous wheel 15 and the synchronous belt 16, so as to drive the traction seat 13 to move downward through the threaded rod 14, so that the traction seat 13 drives the guide rod 11 to move downward through the connecting plate 12 to assist in limiting it from the top of the rear cover 1.

[0034] Embodiment 2:

[0035] In the above embodiment, the rear cover 1 is positioned by a vertical connection between the rear cover 1 and the positioning rod 4, but this method has certain limitations and cannot fix a smaller rear cover 1. Therefore, in this embodiment, a supporting seat 23 is fixedly provided on the surface of the positioning rod 4, one side of the supporting seat 23 is provided as an arc surface, and a retaining edge 24 is horizontally provided at the bottom of the supporting seat 23.

[0036] See also Figure 3 and 4 The motor 9 drives the driving shaft 10 to rotate, so that the driving shaft 10 drives the driving disk 5 to rotate through the main shaft 7. After the driving disk 5 rotates, it can drive the positioning rod 4 to move in the slide groove 6 through the connecting arm 8. First, the smaller rear cover 1 is placed between the five supporting seats 23, so that the bottom of the rear cover 1 contacts the retaining edge 24, and then the five supporting seats 23 are used to clamp the rear cover 1 by adjusting the position of the positioning rod 4, thereby realizing another fixing method of the rear cover 1, so as to facilitate the processing of the rear cover 1.

[0037] It should be noted that if the back cover 1 is fixed in the manner of Example 1, the supporting seat 23 can support and limit the back cover 1 in the vertical direction, so that the back cover 1 stays at a certain height unchanged, so as to facilitate the processing of the back cover 1. In Example 1, the surface of the positioning rod 4 needs to be processed with a specification of a small diameter at the upper end and a large diameter at the lower end, so that the upper end of the positioning rod 4 can support the back cover 1 through the part with gradually increasing diameter when it extends into the through hole of the back cover 1.

[0038] Working principle: When in use, start the motor 9, and drive the drive shaft 10 to rotate through the motor 9. The drive shaft 10 can drive the main shaft 7 to rotate synchronously through the block 21 and the slot 20, and the main shaft 7 can drive the drive plate 5 to rotate, so that the drive plate drives the positioning rod 4 to move inside the slide groove 6 through the connecting arm 8. When the size of the positioning rod 4 is adjusted to match the size of the rear cover 1, turn off the motor 9, place the rear cover 1 on the top of the positioning rod 4, so that the top of the positioning rod 4 extends into the through hole of the rear cover 1, and then restart the motor 9. When the drive shaft 10 rotates, it can drive the threaded rod 14 to rotate synchronously through the synchronous wheel 15 and the synchronous belt 16, so that the traction seat 13 can drive the guide rod 11 downward through the connecting plate 12, thereby realizing the auxiliary fixation of the guide rod 11 to the rear cover 1.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
