Description

Technical Field

[0001] The invention relates to the technical field of compressor production, in particular to a picking and placing device for trimming a scroll compressor blank. Background Art

[0002] In compressor production, most of them are completed by gravity casting. The casting model is generally a plurality of molding cavities distributed circumferentially along the casting port at equal intervals, so that multiple single blanks are connected to the casting head in the middle through the connecting part. The connecting part needs to be cut off later. When multiple single blanks and the casting head in the middle are picked up and placed at the same time, a scroll compressor blank trimming pick-up and placement device is required. The current scroll compressor blank trimming picking and placing device, for example, the multifunctional scroll compressor blank trimming picking and placing device proposed in publication number: CN215033535U, includes a fixed seat, a pneumatic chuck 1 for clamping the blank as a whole before trimming, and multiple pneumatic chucks 2 for clamping each individual blank after trimming, and the pneumatic chucks 2 and the pneumatic chucks 1 are installed on the same side of the fixed seat. The utility model is provided with two groups of pneumatic chucks 1 and 2 for clamping the blank before trimming and the individual blank after trimming, respectively. The two clamps are used to clamp the blanks in different states, respectively, so as to realize full-process automated production and greatly improve production efficiency.

[0003] When the existing scroll compressor blank trimming picking and placing device is used, although the pneumatic chuck 1 and the pneumatic chuck 2 are respectively used to clamp the blanks in different states, the whole process of automated production can be realized, and the production efficiency is greatly improved. However, it is found during use that the device uses multiple sets of pneumatic chucks to pick up and place the workpiece. The multiple sets of pneumatic chucks not only require multiple telescopic rods for control, which not only makes the control system complicated, but also makes the cost of the picking and placing device high. Moreover, if a telescopic rod is damaged or the telescopic amount is insufficient, it will affect the picking and placing of the workpiece, making the workpiece stable and inconvenient to use when picking and placing the workpiece. Therefore, we propose a scroll compressor blank trimming picking and placing device to solve the problem raised. Summary of the invention

The bottom of the fixed frame 7 is fixedly connected to the first clamping claw plate 9, and a sliding frame 10 is slidably arranged on the guide rod 8. The sliding frame 10 is sleeved on the guide rod 8 through the guide groove 11. The bottom of the sliding frame 10 is fixedly connected to the second clamping claw plate 12, and the first clamping claw plate 9 and the second clamping claw plate 12 are symmetrically rotatably connected to the bottom of the ring side with the clamping claw 13; A guide rod groove 14 is penetrated in the middle of the first clamping jaw plate 9 and the connecting frame 5, and a guide rod groove 14 is also penetrated in the middle of the sliding frame 10 and the second clamping jaw plate 12.

The lifting frame 3 is slidably provided with a sliding seat 18 at the bottom of the guide rod 8. The top of the guide rod 15 in the first clamping jaw plate 9 is fixedly connected to the lifting frame 3, and the top of the guide rod 15 in the second clamping jaw plate 12 is fixedly connected to the sliding seat 18. The spacing between the second clamping jaw plates 12 is adjusted by an adjustment mechanism; The lifting frame 3 is lifted and lowered by the hydraulic rod 4, and the lifting frame 3 drives the guide rod 15 inside the second clamping plate 12 to move through the sliding frame 10. At the same time, the lifting frame 3 directly drives the guide rod 15 inside the first clamping plate 9 to move, thereby driving the first clamping plate 9 and the transmission frame 16 at the bottom of the second clamping plate 12 to lift and lower synchronously. When the transmission frame 16 is lifted and lowered, it drives the first clamping plate 9 and the clamping jaws 13 at the bottom of the second clamping plate 12 to complete the clamping or releasing action synchronously through the transmission rod 17. Through this picking and placing device, multiple groups of clamping structures can be driven to work synchronously through a single hydraulic rod 4, which not only effectively saves the production and maintenance costs of the picking and placing device for trimming the compressor blank, but also improves the stability of the clamping of the compressor blank.

When the sliding frame 10 and the second clamping claw plate 12 move, the sliding frame 10 and the guide rods 8 move relative to each other. The guide structure formed by the guide rods 8 and the guide grooves 11 can guide the movement of the sliding frame 10 and the second clamping claw plate 12 to avoid deviation of the movement of the sliding frame 10 and the second clamping claw plate 12.

[0021] See also Figures 1 to 6 The guide rod 15 is a cylinder, and the outer diameter of the guide rod 15 matches the inner diameter of the guide rod groove 14 . The transmission frame 16 forms a transmission structure with the clamping claw 13 through the transmission rod 17 .

[0022] See also Figures 1 to 6The adjusting mechanism includes a slide groove 19. The slide grooves 19 are symmetrically opened at the bottom of the four sides of the lifting frame 3. A transmission groove 20 is opened in the middle of the inner side of the lifting frame 3. The sliding seat 18 is fixedly connected with a slider 21 at the top corresponding to the slide groove 19. A screw rod 22 with a thread of the slider 21 is rotatably connected in the slide groove 19. One end of the screw rod 22 located in the transmission groove 20 is fixedly connected with a first reversing gear 23. A motor 24 is installed in the middle of the top of the lifting frame 3. The motor 24 is fixedly connected with a second reversing gear 25 at the shaft end corresponding to the first reversing gear 23. The slide groove 19 and the slider 21 are T-shaped, and the internal size of the slide groove 19 coincides with the external size of the slider 21. The texture direction of the external thread of the screw rod 22 in the relative position inside the lifting frame 3 is the same. The first reversing gear 23 and the second The reversing gears 25 are perpendicular to each other, and the first reversing gear 23 is meshed with the second reversing gear 25. When the spacing of the second clamping plate 12 needs to be adjusted according to the size of the compressor blank, the second reversing gear 25 is driven to rotate by the motor 24, so that the second reversing gear 25 drives the first reversing gears 23 on the four sides to rotate simultaneously through meshing, and then drives the screw rods 22 on the four sides to rotate simultaneously. When the screw rod 22 rotates, it drives the slider 21 to move in the slide groove 19, and the slider 21 drives the sliding seats 18 on the four sides to approach or move away at the same time, and the sliding seat 18 drives the sliding frame 10 and the second clamping plate 12 to move through the guide rod 15, and then can drive the second clamping plates 12 on the four sides to approach or move away at the same time, so as to adjust the spacing of the second clamping plate 12 in production.

[0023] Working principle: When the pick-and-place device for trimming the scroll compressor blank is used, first, the lifting frame 3 is driven to lift by the hydraulic rod 4, and the lifting frame 3 drives the guide rod 15 inside the second clamping claw plate 12 to move through the sliding frame 10, and at the same time, the lifting frame 3 directly drives the guide rod 15 inside the first clamping claw plate 9 to move, thereby driving the first clamping claw plate 9 and the transmission frame 16 at the bottom of the second clamping claw plate 12 to lift synchronously. When the transmission frame 16 is lifted or lowered, it drives the first clamping claw plate 9 and the clamping claws 13 at the bottom of the second clamping claw plate 12 to complete the clamping or releasing action synchronously through the transmission rod 17. Through the pick-and-place device, multiple groups of clamping structures can be driven to work synchronously through a single hydraulic rod 4, which not only effectively saves the production and maintenance costs of the pick-and-place device for trimming the compressor blank, but also improves the stability of clamping the compressor blank. When it is necessary to adjust the spacing of the second clamping claw plate 12 according to the size of the compressor blank, The second reversing gear 25 is driven to rotate by the motor 24, so that the second reversing gear 25 drives the first reversing gears 23 on the four sides to rotate simultaneously through meshing, thereby driving the screw rods 22 on the four sides to rotate simultaneously. When the screw rods 22 rotate, they drive the slider 21 to move in the slide groove 19, and the slider 21 drives the sliding seats 18 on the four sides to approach or move away at the same time. The sliding seat 18 drives the sliding frame 10 and the second clamping claw plate 12 to move through the guide rod 15, thereby being able to drive the second clamping claw plates 12 on the four sides to approach or move away at the same time, so as to adjust the spacing of the second clamping claw plate 12 during production. When the sliding frame 10 and the second clamping claw plate 12 move, the sliding frame 10 and the guide rod 8 produce relative movement. The guiding structure formed by the guide rod 8 and the guide groove 11 can guide the movement of the sliding frame 10 and the second clamping claw plate 12 to avoid deviation of the movement of the sliding frame 10 and the second clamping claw plate 12.
