Description

Technical Field

[0001] The utility model relates to the field of compressor housing grinding, in particular to a burr grinding device for compressor housing sheet metal. Background Technique

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving a piston through the operation of the motor, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle.

[0003] During the production process of the compressor, it is necessary to process the compressor housing. When processing, holes are often drilled in the compressor housing. After drilling, there are many burrs in the hole groove. At this time, it is necessary to grind the burrs generated by drilling the compressor housing. However, during the grinding process, a large number of fine metal chips will be generated. Once they fall into the interior of the grinding device, it is difficult to take them out, which is not conducive to cleaning and thus affects work efficiency. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a burr grinding device for compressor housing sheet metal to solve the technical problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A burr grinding device for compressor housing sheet metal, including a workbench, guide rails are fixedly installed on both sides of the workbench, and a driving plate is movably installed on one side of the guide rail. One end of the driving plate is movably installed with a grinding block. One end of the workbench is movably installed with a movable column, and a collection trough is fixedly installed at one end of the movable column. A ventilation opening is fixedly installed on one side of the collection trough, and a fixed rod is fixedly installed at one end of the ventilation opening. A shielding block is fixedly installed at one end of the fixed rod. A discharge port is opened on one side of the workbench, and a dust suction pipe is fixedly installed inside the discharge port. An air duct motor is fixedly installed on one side of the dust suction pipe, and a rotating shaft is movably installed at one end of the air duct motor. A fan blade is fixedly installed on the outer side of the rotating shaft.

[0006] By adopting the above technical scheme, through the arrangement of the collection trough and the discharge port, during the grinding process, the metal chips can fall into the interior of the collection trough. Thus, through the suction of the fan blade, the chips in the collection trough can enter the dust suction pipe through the ventilation opening and be discharged through the discharge port. Through the arranged shielding block, when not grinding, the shielding block can block the dust suction pipe to avoid the problem that the dust suction pipe affects the air inside the workbench and causes dust in the air to enter the interior of the workbench.

[0007] The present utility model is further configured such that a connecting rod is fixedly installed on one side of the movable column, and clamping plates are movably installed on both sides of the workbench. A fixing block is fixedly installed on one side of the clamping plate, and a steel cable is installed on one side of the fixing block. The fixing block and the connecting rod are connected by the steel cable, and a return spring is arranged on one side of the clamping plate.

[0008] By adopting the above technical solution, by setting the clamping plates, the outer shell plate of the compressor can be fixed, avoiding problems such as shaking or wobbling of the plate during the grinding process, which affects the grinding. The plate can be limited, making the overall grinding effect more stable and preventing the problem of grinding deviation.

[0009] The present utility model is further configured such that pulleys are arranged on both sides of the steel cable, and the pulleys are rotatably connected to the workbench. Support rods are fixedly installed on both sides of the workbench, and the support rods cooperate with the connecting rod.

[0010] By adopting the above technical solution, by setting the pulleys, the friction can be reduced during the pulling process. At the same time, when the connecting rod moves, the support rods can pull in a timely manner to avoid the problem that the clamping plates do not move in time, resulting in the plate being unable to enter the inside of the clamping plates.

[0011] The present utility model is further configured such that a spring is installed at one end of the movable column, and the movable column is connected to the workbench through the spring. A hole groove matching the movable column is opened inside the workbench.

[0012] By adopting the above technical solution, by setting the spring, the movable column can have sufficient reset effect, avoiding problems that make it difficult to carry out subsequent work normally.

[0013] The present utility model is further configured such that a driving device is installed inside the driving plate and connected to the grinding block, and the outer side of the grinding block is made of a frosted material.

[0014] By adopting the above technical solution, through the setting of the driving plate, the grinding block can rotate stably. At the same time, the outer side of the grinding block is made of a frosted material, which will not affect the normal work of the movable column and avoid grinding the movable column.

[0015] In summary, the present utility model mainly has the following beneficial effects:

[0016] The utility model is provided with a collection tank and a discharge port. During the grinding process, metal debris can fall into the interior of the collection tank. Thus, through the suction of the fan blades, the debris inside the collection tank can enter the interior of the dust suction pipe through the ventilation port and then be discharged through the discharge port. By providing a shielding block, when not grinding, the shielding block can block the dust suction pipe, preventing the dust suction pipe from affecting the air inside the workbench and avoiding the problem of dust in the air entering the interior of the workbench. At the same time, by providing a movable column and a clamping plate, when placing the compressor housing plate, the movable column can support the compressor housing plate. When the movable column descends, the clamping plate moves towards the middle, and the support of the compressor housing plate is gradually replaced by the clamping plate. During the grinding process, the compressor housing plate can be made more stable and will not shake due to the force generated during grinding, making the overall grinding more effective and improving the overall work efficiency.

[0024] Next, the embodiments of the present utility model will be described according to its overall structure.

[0025] A burr grinding device for a compressor housing sheet metal, as Figures 1-5As shown in the figure, it includes a workbench 1. Guide rails 2 are fixedly installed on both sides of the workbench 1. A driving plate 3 is movably installed on one side of the guide rail 2. A grinding block 4 is movably installed at one end of the driving plate 3. A movable column 5 is movably installed at one end of the workbench 1. A collecting groove 6 is fixedly installed at one end of the movable column 5. A ventilation opening 8 is fixedly installed on one side of the collecting groove 6. A fixing rod 9 is fixedly installed at one end of the ventilation opening 8. A shielding block 10 is fixedly installed at one end of the fixing rod 9. A discharge port 15 is provided on one side of the workbench 1. A dust suction pipe 11 is fixedly installed inside the discharge port 15. An air pipe motor 12 is fixedly installed on one side of the dust suction pipe 11. A rotating shaft 13 is movably installed at one end of the air pipe motor 12. A fan blade 14 is fixedly installed on the outer side of the rotating shaft 13. When the grinding block 4 rotates, it can grind the holes of the compressor outer shell plate. The debris generated by grinding falls into the collecting groove 6. When the movable column 5 moves downward, it drives the collecting groove 6 to move downward, so that the ventilation opening 8 drives the fixing rod 9 to move downward, and finally pushes the shielding block 10 to move downward. When the shielding block 10 moves downward, the dust suction pipe 11 loses the shielding of the shielding block 10 on one side. At the same time, the dust suction pipe 11 supports the ventilation opening 8 on one side. At this time, the dust suction pipe 11 is communicated with the ventilation opening 8. When the air pipe motor 12 is started, it can make the rotating shaft 13 rotate, so that the fan blade 14 rotates to realize the suction operation.

[0026] Please refer to Figure 2 、 4 As shown in the figure, a connecting rod 7 is fixedly installed on one side of the movable column 5. Clamping plates 18 are movably installed on both sides of the workbench 1. A fixing block 17 is fixedly installed on one side of the clamping plate 18. A steel cable 16 is installed on one side of the fixing block 17. The fixing block 17 and the connecting rod 7 are connected by the steel cable 16. A return spring is provided on one side of the clamping plate 18. By setting the clamping plate 18, the compressor outer shell plate can be fixed, avoiding the problem that the plate shakes or vibrates during the grinding process, which affects the grinding. The plate can be limited, making the overall grinding effect more stable and avoiding the problem of grinding deviation.

[0027] Please refer to Figure 4 As shown in the figure, pulleys 21 are provided on both sides of the steel cable 16. The pulleys 21 are rotatably connected to the workbench 1. Support rods 20 are fixedly installed on both sides of the workbench 1. The support rods 20 cooperate with the connecting rod 7. By setting the pulleys 21, the friction can be reduced during the pulling process. At the same time, when the connecting rod 7 moves, the support rods 20 can pull in time to avoid the problem that the clamping plate 18 does not move in time, resulting in the plate being unable to enter the clamping plate 18.

[0028] Please refer to Figure 3 As shown in the figure, a spring 19 is installed at one end of the movable column 5. The movable column 5 and the workbench 1 are connected by the spring 19. A hole groove matching with the movable column 5 is provided inside the workbench 1. By setting the spring 19, the movable column 5 can have sufficient reset effect, avoiding the problem that the subsequent work is difficult to proceed normally.

[0029] Please refer to Figure 1 , a driving device is installed inside the driving board 3 and connected to the grinding block 4, and the outer side of the grinding block 4 is made of abrasive material. The setting of the driving board 3 enables the grinding block 4 to rotate stably. At the same time, the outer side of the grinding block 4 is made of abrasive material, which will not affect the normal operation of the movable column 5 and avoid grinding the movable column 5.

[0030] Please refer to Figure 5 , an empty slot matching the shielding block 10 is opened at one end of the dust suction pipe 11, and the inside of the collection tank 6 communicates with the outside through the ventilation port 8. Through the empty slot opened at one end of the dust suction pipe 11, the shielding block 10 has sufficient moving space, and at the same time, a limiting effect is exerted on the shielding block 10.

[0031] The working principle of the present utility model is as follows: When the guide rail 2 is started, the driving board 3 descends, so that the grinding block 4 is inserted into the hole of the compressor housing plate, and then the movable column 5 is squeezed to move the movable column 5 downward. At the same time, the spring 19 is squeezed. When the movable column 5 moves downward, the connecting rod 7 is driven to move downward, so that the connecting rod 7 pulls the steel cable 16. Under the action of the pulley 21, the fixed block 17 moves toward the middle, driving the clamping plate 18 to displace, and then pulling the return spring on one side of the clamping plate 18. At this time, the role of the movable column 5 in bearing the compressor housing plate is gradually replaced by the clamping plate 18, so that the clamping plate 18 clamps the compressor housing plate. At this time, the driving board 3 is started to make the grinding block 4 rotate. When the grinding block 4 rotates, it can grind the hole of the compressor housing plate. The debris generated by the grinding falls into the collection tank 6. When the movable column 5 moves downward, the collection tank 6 is driven to move downward, so that the ventilation port 8 drives the fixed rod 9 to move downward, and finally pushes the shielding block 10 to move downward. When the shielding block 10 moves downward, one side of the dust suction pipe 11 loses the shielding of the shielding block 10, and at the same time, one side of the dust suction pipe 11 supports the ventilation port 8. At this time, the dust suction pipe 11 communicates with the ventilation port 8. When the air duct motor 12 is started, the rotating shaft 13 can be rotated, so that the fan blade 14 rotates to realize the suction operation. At this time, the metal debris inside the collection tank 6 enters the ventilation port 8, and then is discharged to one side through the dust suction pipe 11 through the discharge port 15, avoiding the problem of debris being discharged into the workbench 1.
