Description

Technical Field

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

[0002] A pump is a machine that transports fluids or pressurizes fluids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids. The most important part in the pump body is the pump cover, which is used to connect the pump shaft and protect the internal structure of the pump shaft.

[0003] The existing pump cover needs to be polished during the production process. When the pump cover is polished, it is usually fixed by clamping fixtures and other fixings to prevent it from shifting during polishing. However, after the pump cover is fixed by the fixings, the fixed part cannot be polished and needs to be polished multiple times, so it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] According to the overall structure of the device, the opening of the pump cover that needs to be polished is passed through the limit rod 8, and then the fixed seat 4 is driven to move closer to each other by the hydraulic rod 3, so that the fixing grooves of the fixed wheel 5 clamp and fix the two ends of the pump cover that needs to be polished, and then one of the fixed wheels 5 is driven to rotate by the drive motor three 16. Since the setting of the anti-slip sleeve 7 increases the friction between the pump cover and the fixed wheel 5, the clamped pump cover can rotate in the fixed seat 4, and the clamped position is continuously changed. At this time, the upper grinding wheel 17 and the lower grinding wheel 18 are driven downward by the upper cylinder 11 and the lower cylinder 12 respectively, and then the upper grinding wheel 17 and the lower grinding wheel 18 are driven to rotate by the drive motor one 6 and the drive motor two 15 to polish the pump cover, so that both sides of the pump cover can be polished and will not be blocked by the fixing parts.

[0028] like Figure 2As shown, the lower grinding assembly includes a lower mounting frame 10, a lower cylinder 12, a lower mounting plate 14, a driving motor 15 and a lower grinding wheel 18.

[0029] By setting the lower mounting frame 10, the lower cylinder 12, the lower mounting plate 14, the driving motor 15 and the lower grinding wheel 18, the lower cylinder 12 can drive the lower grinding wheel 18 to move to the grinding position, and then the driving motor 15 drives the lower grinding wheel 18 to rotate to grind the bottom surface of the pump cover.

[0030] like Figure 3 As shown, the fixing assembly includes a mounting platform 2, a hydraulic rod 3, a fixing seat 4 and a fixing wheel 5, the mounting platforms 2 are fixedly installed at both ends of the top surface of the grinding table 1, and a mounting opening is penetrated through the side of the mounting platform 2, and a hydraulic rod 3 is fixedly installed on the inner wall of the mounting opening of the mounting platform 2, and the movable end of the hydraulic rod 3 is fixedly connected with the fixing seat 4, the fixing seat 4 is an arc-shaped seat with an opening penetrated through the side and a hollow interior, the upper end and the lower end of the inner wall of the fixing seat 4 are fixedly installed with a shaft seat, and a connecting shaft is sleeved on the inner wall of the shaft seat, and the arc surface of the connecting shaft of the fixing seat 4 is fixedly connected with a fixing wheel 5, and a fixing groove is opened on the arc surface of the fixing wheel 5, and an anti-slip sleeve 7 is fixedly sleeved on the inner wall of the fixing groove, and a driving motor 3 16 is fixedly installed on the top surface of the fixing seat 4 on the left side of the grinding table 1, and the output end of the driving motor 3 16 penetrates the fixing seat 4 and is fixedly connected to one end of one of the connecting shafts of the fixing seat 4.

[0031] By setting the mounting platform 2, hydraulic rod 3, fixed seat 4, fixed wheel 5, anti-skid sleeve 7 and driving motor three 16, the fixed seat 4 is driven to move closer to each other through the hydraulic rod 3, so that the fixing groove of the fixed wheel 5 clamps and fixes the two ends of the pump cover to be polished, and then one of the fixed wheels 5 is driven to rotate by the driving motor three 16. Since the setting of the anti-skid sleeve 7 increases the friction between the pump cover and the fixed wheel 5, the clamped pump cover can rotate in the fixed seat 4, and the clamped part is continuously changed.

[0032] like Figure 4 As shown, the auxiliary fixing assembly includes a limiting rod 8, a mounting seat 19 and a screw 20. The mounting seat 19 is fixedly mounted on the inner wall of the lower mounting frame 10. The screw 20 is fixedly mounted on the top surface of the mounting seat 19. The interior of the limiting rod 8 is hollow and has a thread. An opening is penetrated through the bottom surface of the limiting rod 8. The limiting rod 8 is threadedly connected to the screw 20.

[0033] By means of the provided limiting rod 8, mounting seat 19 and screw 20, the opening on the top surface of the pump cover can pass through the limiting rod 8 before being fixed, so that it can be further limited by the limiting rod 8 during grinding, so that the fixing effect is better. At the same time, the limiting rod 8 can be replaced by rotating the limiting rod 8 and the screw 20.

[0034] Working principle: the opening of the pump cover to be polished is passed through the limit rod 8, and then the fixed seat 4 is driven to move closer to each other through the hydraulic rod 3, so that the fixing groove of the fixed wheel 5 clamps and fixes the two ends of the pump cover to be polished, and then one of the fixed wheels 5 is driven to rotate by the drive motor three 16. The setting of the anti-slip sleeve 7 increases the friction between the pump cover and the fixed wheel 5, so that the clamped pump cover can rotate in the fixed seat 4, and the clamped position is continuously changed. At this time, the upper grinding wheel 17 and the lower grinding wheel 18 are driven downward by the upper cylinder 11 and the lower cylinder 12 respectively, and then the upper grinding wheel 17 and the lower grinding wheel 18 are driven to rotate by the drive motor one 6 and the drive motor two 15 to polish the pump cover, so that both sides of the pump cover can be polished.
