DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] refer to Figure 1 A piston processing device for a refrigeration compressor includes a workbench 1. An electric slide rail 2 is symmetrically fixed on the upper surface of the workbench 1. The electric slide rail 2 is a prior art and does not need to be drawn and described in detail. A slider 1 3 is slidably provided on the inner surface of the electric slide rail 2. A telescopic cylinder 2 5 is fixedly provided on the outer surface of the left slider 1 3. A stop block 6 is fixedly provided on the outer end surface of the piston rod of the telescopic cylinder 2 5. At the same time, a clamping assembly 4 is fixedly provided on the outer surface of the right slider 1 3.

[0027] refer to Figure 2-3 The clamping assembly 4 includes a support column 401, and two groups of support columns 401 are symmetrically fixed on the outer surface of the slider 3. The outer surface of the support column 401 is fixedly provided with a connecting plate 402, and the outer surface of the connecting plate 402 is rotatably provided with a square frame 403. The outer surface of the square frame 403 is fixedly provided with a disc 405, and the outer surface of the disc 405 is provided with a plurality of slide grooves 406. The inner surface of the slide groove 406 is slidably provided with a slide plate 407. The outer surface of the slide plate 407 is provided with a fixing hole 417, and the inner surface of the fixing hole 417 is slidably provided with a fixing plate 416. The two side surfaces of the fixing plate 416 are fixedly connected to the inner surface of the slide groove 406. At the same time, the outer surface of the slide plate 407 is fixedly provided with a plurality of silicone anti-slip pads 408 to avoid sliding during the processing process and ensure the stability of the clamping.

[0028] refer to Figure 2-Figure 4The outer surface of the disc 1 405 is provided with a connecting column 409, which penetrates the disc 1 405 for sliding fit. The outer surface of the connecting column 409 is fixedly provided with a disc 2 410. The outer surface of the disc 2 410 is provided with a plurality of slots 411. The positions of the slots 411 correspond to the positions of the slide slots 406 provided on the disc 1 405. The inner surface of the slots 411 is symmetrically fixed with a clamping plate 1 412. A hinge plate 413 is rotatably provided between the two clamping plates 1 412. At the same time, a clamping plate 2 414 is symmetrically fixed on the outer side of the slide plate 407. The other end of the hinge plate 413 is rotatably provided between the two clamping plates 2 414.

[0029] A telescopic cylinder 404 is fixedly provided on the inner surface of the square frame 403. The outer end surface of the piston rod of the telescopic cylinder 404 passes through the disc 405 and is fixedly connected to the connecting column 409. The telescopic movement of the telescopic cylinder 404 drives the connecting column 409 to move, thereby changing the angle between the hinge plate 413 and the slide 407, and then drives the slide 407 to slide in the slide groove 406, adapting to the sizes of the inner holes of different pistons. Combined with the force of the block 6, it can achieve stable fixation of pistons of different sizes.

[0030] refer to Figure 2 A motor 415 is fixedly provided on the outer side surface of the connecting plate 402. The output shaft of the motor 415 passes through the connecting plate 402 and is fixedly connected to the square frame 403. Starting the motor 415 drives the square frame 403 to rotate, and then drives the piston fixed by the clamping assembly 4 to rotate. When drilling the outer side surface of the piston, there is no need to manually adjust the processing position, which ensures the accuracy of the processing position and expands the processing area. At the same time, the length of the slide plate 407 is longer than the length of the piston, so the position of the slide plate 407 in the inner hole of the piston can be better observed, which facilitates processing in the gap between the two slide plates 407 and determines the processing position.

[0031] refer to Figure 1 The upper surface of the workbench 1 is fixedly provided with a support plate 7, and the outer surface of the support plate 7 is symmetrically fixed with a side plate 8. A screw 9 and a guide rod 10 are respectively provided between the two side plates 8. The screw 9 rotates with the side plates 8 on both sides, and the guide rod 10 is fixed with the side plates 8 on both sides. The surface thread of the screw 9 is provided with a slider 2 11. At the same time, the guide rod 10 passes through the slider 2 11 and makes a sliding fit, and the slider 2 11 makes a sliding fit with the outer surface of the support plate 7 to prevent the slider 2 11 from flipping during the sliding process. The guide rod 10 limits the slider 2 11 so that it can slide smoothly.

[0032] A motor 2 15 is fixedly provided on the outer end surface of the right side panel 8. The output shaft of the motor 2 15 is fixedly connected to one end of the screw 9. Starting the motor 2 15 drives the screw 9 to rotate, thereby controlling the left and right movement of the slider 2 11. The outer side surface of the slider 2 11 is fixedly connected to the telescopic cylinder 3 12. The bottom of the piston rod of the telescopic cylinder 3 12 is fixedly connected to the drilling component 13. The drilling component 13 here is existing technology, so there is no need to describe and draw it in detail here and in the accompanying drawings.

[0033] refer to Figure 5-Figure 6 A U-shaped cover 14 is fixedly provided on the outer surface of the telescopic cylinder 3 12, and a water inlet hole 141 is provided on the outer surface of the U-shaped cover. At the same time, a through groove 16 is provided on the outer surface of the support plate 7, and a collection box 17 is slidably provided on the inner surface of the through groove 16. The bottom surface of the collection box 17 is slidably matched with the upper surface of the workbench 1, which makes it convenient to pull out the collection box 17 for subsequent cleaning. In addition, a filter plate 18 is fixedly provided on the inner surface of the collection box 17, and a water outlet hole 171 is provided on the outer side of the collection box 17 below the filter plate 18.

[0034] refer to Figure 5 A water pump 19 is fixedly provided on the upper surface of the support plate 7. A water inlet pipe 21 and a water outlet pipe 20 are fixedly provided on both sides of the water pump 19. The water inlet pipe 21 is connected to the water inlet hole 141 on the upper surface of the U-shaped cover, and the water outlet pipe 20 is connected to the water outlet hole 171 on the outer side of the collection box 17.

[0035] When drilling the outer side of the piston, the water pump 19 draws water from the collection box 17 and flows through the water inlet pipe 21 to spray water on the drill bit, effectively reducing the temperature of the drill bit and preventing the drill bit from burning or wearing due to overheating. At the same time, the debris generated during the processing is flushed to prevent it from adhering to the outer surface of the drill bit and affecting subsequent processing. After the processing is completed, the debris and water fall into the collection box 17, the debris is filtered by the filter plate 18, and the water flows into the collection box 17 below the filter plate 18, realizing the reuse of water resources and saving water resources.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction.
