Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a grinding device used for pump processing. Background Art

[0002] Grinding in pump processing is a key process to ensure product performance, surface quality and service life. It is mainly used to grind the end face of the pump body to eliminate burrs, flash and tool marks generated during milling, turning, casting and other processing processes.

[0003] For example, the Chinese patent publication number CN222449845U states, "A water pump casing grinding and positioning device includes a grinding and positioning device body, a protective mechanism, and a processing mechanism. A grid is mounted on the grinding and positioning device body, the protective mechanism is mounted on the grinding and positioning device body, the protective mechanism includes a pair of protective covers, the grinding and positioning device body is provided with a pair of first sliding grooves matching the protective covers, the grinding and positioning device body is provided with a pair of threaded rods, the pair of threaded rods are arranged through the grinding and positioning device body, and the pair of protective covers are matched with the threaded rods respectively."

[0004] The water pump casing grinding and positioning device in the above-mentioned cited document is provided with a corresponding mechanism on the water pump casing grinding and positioning device, so that when the water pump casing is ground, the debris generated during the grinding can be blocked by the lifting of the lifting mechanism. At the same time, the debris will be sucked to the bottom of the grinding and positioning device, so that the debris can be centrally processed without harming the workers.

[0005] However, when polishing the above-mentioned water pump housing, after the pump housing is clamped by the clamping plates on both sides and the upper end surface is polished first, the pump housing needs to be disassembled from the clamping assembly, turned over and re-fixed before the lower surface can be polished. This makes the polishing steps of the upper and lower end surfaces of the pump housing cumbersome, and the debris adhered to the polishing surface during polishing needs to be manually wiped off after turning over to prevent scratches caused by squeezing between the polishing surface and the processing table. The polished debris is easily stuck on the grille when it is discharged through the grille below, and it also needs to be manually cleaned from time to time. Utility Model Content

[0041] Based on Example 1, this example introduces a grinding device for pump processing, such as Figure 4 、 Figure 6 As shown,

[0042] The first brush plates 600 are movably mounted on both sides of the top of the guide plate 11. A guide rod 61 and a bidirectional screw rod 62 are mounted on both sides of the inner wall of the waste trough 111.

[0045] Among them, the negative pressure fan 500 is fixedly installed on both sides of the inner wall of the waste trough 111, and a transmission shaft is fixedly installed between the output shaft of the negative pressure fan 500 located on the back of the grinding table 100 and the end shaft of the active bevel gear 51. The outer edge of the active bevel gear 51 is meshed with the outer edge of the passive bevel gear 621. The two sets of negative pressure fans 500 can form a negative pressure in the waste trough 111, so that the grinding chips on the pad 12 can fall from the grid groove, and the negative pressure fan 500 located on the back of the grinding table 100 drives the active bevel gear 51 through the transmission shaft, so that the bidirectional screw rod 62 The upper passive bevel gear 621 is driven synchronously, so that the two groups of first brush plates 600 can slide back and forth along the guide rod 61, thereby clearing the grinding debris stuck in the grille groove on the pad 12. The surface of the bidirectional screw 62 is processed into a smooth mirror structure, and a corrugated folded metal plate can be installed between the waste trough 111 and the side of the first brush plate 600, which can be used to prevent metal debris on the surface of the bidirectional screw 62 from entering the screw groove and causing jamming problems. The anti-jamming technical solution for the surface of the bidirectional screw 62 is an existing mature technical solution and will not be elaborated here.

[0046] Among them, the guide rod 61 is fixedly installed between the inner wall of the waste trough 111 and the gear box 800, and the bidirectional screw rod 62 is rotatably installed in the inner wall of the waste trough 111. The two groups of first brush plates 600 are respectively connected to the bidirectional screw rod 62 through threaded cooperation, and the two groups of first brush plates 600 are respectively slidably nested on the outside of the two corresponding guide rods 61. The brush on the top of the first brush plate 600 extends into the interior of the pad 12. The negative pressure fan 500 located on the back of the grinding table 100 drives the active bevel gear 51 through the transmission shaft, so that the passive bevel gear 621 on the bidirectional screw rod 62 is driven synchronously, so that the two groups of first brush plates 600 can slide back and forth along the guide rod 61, thereby guiding the grinding debris stuck in the grille groove on the pad 12 into the guide plate 11 for centralized discharge.

[0047] In this embodiment, the two sets of negative pressure fans 500 can form a negative pressure in the waste trough 111, so that the grinding chips on the backing plate 12 can fall out of the grille groove, and the negative pressure fan 500 located on the back of the grinding table 100 drives the active bevel gear 51 through the transmission shaft, so that the passive bevel gear 621 on the bidirectional screw rod 62 is synchronously driven, so that the two sets of first brush plates 600 can slide back and forth along the guide rod 61, thereby dredging the grinding chips stuck in the grille groove on the backing plate 12 and entering the guide plate 11 for centralized discharge;

[0048] Working principle: When grinding the pump housing, first place the pump housing on top of the second brush plate 71, and then squeeze the second brush plate 71 and the grid plate 700 into the open groove 121 for positioning. The clamping cylinder 41 at the end opening of the connecting plate 400 can clamp the pump housing in the center and position it on the pad 12 through the clamping plate 42 at the telescopic end.

[0049] Then, the cylinder in the grinding assembly 200 can be extended and retracted to drive the grinding disc to grind the top of the pump housing;

[0050] When the bottom surface of the pump casing is polished after the top surface is polished, the fixed plate 32 can be driven to slide near the top in the guide rail 31 by the telescopic end of the jacking cylinder 300, and then the worm gear reduction motor 33 can drive the connecting plate 400 and the pump casing clamped in the end clamping cylinder 41 and the clamping plate 42 to flip over for a circle, and then the pump casing after flipping can be driven to fall back onto the pad 12 by the jacking cylinder 300. During this process, the driving motor 72 and the pressing switch 73 below are in a distance state, and the driving motor 72 is in a working state, driving the second brush plate 71 to rotate, and can clean the polished surface of the lower part of the pump casing after flipping over, and clean the metal debris adhered to the surface in time to avoid scratches when it conflicts with the pad 12 in the future. After the pump casing after flipping over is pressed down to the second brush plate 71 and the grid plate 700 enters the open groove 121, the driving motor 72 conflicts with the pressing switch 73, and the driving motor 72 is in a stopped state.

[0051] During this process, the two sets of negative pressure fans 500 can form negative pressure in the waste trough 111, so that the grinding chips on the backing plate 12 can fall out of the grille groove, and the negative pressure fan 500 located on the back of the grinding table 100 drives the active bevel gear 51 through the transmission shaft, so that the passive bevel gear 621 on the bidirectional screw rod 62 is driven synchronously, so that the two sets of first brush plates 600 can slide back and forth along the guide rod 61, thereby dredging the grinding chips stuck in the grille groove on the backing plate 12 and entering the guide plate 11 for centralized discharge;

[0052] Finally, through the above-mentioned step of turning over the pump casing, the lower polished surface is cleaned of debris to complete the polishing of the upper and lower surfaces of the pump casing and the cleaning of the polished surface.
