Description

Technical Field

[0001] This utility model relates to the field of compressor blank trimming technology, and in particular to a compressor casting blank trimming device. Background Technology

[0002] As a key power equipment, the compressor's internal components are mostly formed using metal casting processes to ensure good strength, sealing performance, and service life. During the manufacturing process, complex parts such as the compressor housing, cylinder, and support are often preliminarily formed blanks through sand casting or precision casting. Surface defects such as burrs, flash, sand holes, and oxide scale will form on the surface of the blanks. If these defects are not repaired and directly put into subsequent processing or assembly, it will cause problems such as dimensional inconsistencies, excessive surface roughness, reduced sealing performance, and reduced fitting accuracy. In severe cases, it may even lead to the failure of the entire machine.

[0003] An existing deburring device for castings (publication number: CN213858469U) has at least the following drawbacks: Although the device can perform grinding without the need for workers to use grinding tools and has high grinding efficiency, when deburring the surface of the blank, although it can initially achieve surface finishing, a large amount of metal shavings and dust are generated during the grinding process in actual use. These shavings usually fly around and accumulate around the equipment or on the surface of the blank, which not only affects the accuracy and efficiency of subsequent processing operations, but also easily causes pollution of the working environment and even damages the equipment. Therefore, there is no special cleaning or collection mechanism, and it is impossible to effectively collect and treat the shavings generated during the grinding process, resulting in the need for manual cleaning after grinding. The operation is cumbersome and inefficient, and it is urgent to improve it. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a compressor casting blank trimming device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] As a further embodiment of this utility model, a suction pump is fixedly connected to the bottom of the inner wall of the trimming cabinet, and a water pipe is fixedly connected to the output end of the suction pump. The top end of the water pipe penetrates the inner wall of the trimming cabinet and extends to the side wall of the placement tray.

[0010] As a further embodiment of this utility model, support blocks are fixedly connected to both sides of the placement tray, and a second electric telescopic rod is fixedly connected between the opposite sides of the support blocks.

The top end of the stabilizing rod 6 penetrates the top of the inner wall of the dressing cabinet 1. The dressing cabinet 1 is equipped with a cleaning mechanism for cleaning impurities after grinding the casting. The cleaning mechanism includes components fixedly connected to the dressing cabinet. A gathering plate 7 is located between the inner walls of the trimming cabinet 1. A lower pressure plate 8 slides through the top of the gathering plate 7 via a support plate. A placement tray 9 is fixedly connected to the top of the lower pressure plate 8. A tension spring 10 is fitted onto the outer wall of the lower pressure plate 8. The top end of the tension spring 10 is fixedly connected to the bottom of the support plate, and the bottom end of the tension spring 10 is fixedly connected to the outer wall of the lower pressure plate 8. A flow pipe 11 connects to the bottom of the gathering plate 7. A movable frame 12 is fixedly connected to the bottom end of the lower pressure plate 8. A filter frame 13 is fixedly connected between the inner walls of the trimming cabinet 1. A filter screen 14 is fixedly connected between the inner walls of the filter frame 13. A scraper 15 is slidably connected to the top of the filter frame 13. The scraper 15 is bow-shaped, and compression springs 16 are fixedly connected to both ends of the scraper 15. One end of the compression spring 16 is fixedly connected to the top of the filter frame 13 by a fixing block. The top of the filter frame 13 has connecting grooves 17 on both sides. Rollers 18 are fixedly connected to the top of the two connecting grooves 17. Pull ropes 19 are fixedly connected to both sides of the scraper 15. The pull ropes 19 are inside the compression springs 16. One end of the pull rope 19 is attached to the top of the roller 18 and passes through the connecting grooves 17 and is fixedly connected to the top of both ends of the movable frame 12. Above, a suction pump 20 is fixedly connected to the bottom of the inner wall of the trimming cabinet 1. A water pipe 21 is fixedly connected to the output end of the suction pump 20. The top end of the water pipe 21 passes through the inner wall of the trimming cabinet 1 and extends to the side wall of the placement tray 9. Support blocks 22 are fixedly connected to both sides of the placement tray 9. A second electric telescopic rod 23 is fixedly connected between the opposite sides of the support blocks 22. A clamping plate 24 is fixedly connected to one end of the second electric telescopic rod 23. The clamping plate 24 is slidably connected to the top of the placement tray 9. A collection frame 25 is fixedly connected to the side wall of the trimming cabinet 1. A discharge port 26 is opened on the side wall of the trimming cabinet 1.

[0023] In this embodiment, when the cleaning mechanism is used, the power supply of the equipment is turned on; then the casting is placed on the top of the placement plate 9. Since the casting itself has a certain weight, when it is placed on the placement plate 9, the placement plate 9 will cause the casting to move downward as a whole, and at the same time stretch the tension spring 10 connected below to achieve the initial position trigger positioning. At the same time, the second electric telescopic rod 23 starts to work, pushing the clamping plate 24 to clamp the casting, ensuring the stability of the casting during the trimming process.

[0024] After the casting is in place, the suction pump 20 is started to draw water stored inside from the top of the dressing cabinet 1 and spray the water onto the surface of the casting through the water pipe 21. The sprayed water is used to cool the grinding disc 5 that generates heat during the subsequent grinding process, and can also effectively inhibit the spread of metal dust and debris.

[0025] Subsequently, the first electric telescopic rod 2 is extended downward, which drives the mounting plate 3 and the servo motor 4 fixed on it to move down, so that the servo motor 4 drives the grinding disc 5 to start working and perform efficient grinding on the burrs on the surface of the casting. The debris generated during the grinding process mixes with the sprayed water and flows to the top of the collecting plate 7, and is guided into the flow pipe 11 through the collecting plate 7, and finally flows into the top of the filter screen 14.

[0026] The filter screen 14 performs solid-liquid separation on the mixture: debris remains on the surface of the filter screen 14, while water seeps into the filter screen 14 and flows back to the bottom of the dressing cabinet 1 for recycling. When a new casting is placed next, the placement tray 9 is pressed down again by the weight of the casting, driving the lower pressure plate 8 to move downward. At the same time, the connected moving frame 12 moves downward and pulls the pull rope 19. Under the action of the pulling force, the pull rope 19 pulls the scraper 15 to slide, while compressing the compression spring 16. The scraper 15 then moves along the top of the filter frame 13, scraping off the debris accumulated on the surface of the filter screen 14 and guiding it to fall into the collection frame 25 through the discharge port 26, thus realizing the automatic collection and cleaning of debris.

[0027] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: This cleaning mechanism structure, through the downward movement of the placement plate 9, drives the lower pressure plate 8, the moving frame 12 and the pull rope 19 to move in tandem, thereby pulling the scraper 15. Under the elastic action of the compression spring 16, the scraper 15 slides along the top of the filter frame 13, effectively scraping the debris accumulated on the surface of the filter screen 14 to the discharge port 26, and finally falling into the collection frame 25. This structure can automatically complete the cleaning of debris during each feeding process without the need for an additional independent drive mechanism, avoiding debris accumulation that affects filtration efficiency. With the linkage of water circulation spray and components such as the collection plate 7, the flow pipe 11, and the filter screen 14, the synchronous collection and processing of debris generated by grinding is achieved, avoiding the spread and accumulation of dust and debris that causes environmental pollution, reducing the frequency of manual cleaning, and effectively improving the cleanliness, automation level and production efficiency of the equipment.
