Description

Technical Field

[0001] This application relates to the field of pump body processing technology, and in particular to a pump body surface polishing and grinding equipment. Background Technology

[0002] Currently, a pump is a machine that transports or pressurizes fluids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. Pumps are mainly used to transport liquids such as water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids. Pumps are generally classified into three categories according to their working principle: positive displacement pumps, dynamic pumps, and other types of pumps. In addition to classification by working principle, they can also be classified and named using other methods.

[0003] In related technologies, Chinese Patent Publication No. CN211760598U discloses a grinding table for pump body processing, including a base and a fixing frame. A hydraulic cylinder is fixedly mounted on the top of the fixing frame, and the hydraulic cylinder is used to drive the movement of the mounting base. A first motor is fixedly mounted on the lower surface of the mounting base, and the first motor drives a rotating disk to rotate through a first rotating shaft. A second motor is fixedly connected to the rotating disk, and the output end of the second motor passes through the rotating disk and is fixedly connected to a housing. A first gear fixedly connected to the second motor is provided inside the housing, and a second gear meshing with the first gear is also provided inside the housing. There are two second gears. A third rotating shaft passes through the second gear and is fixedly connected to the second gear. The third rotating shaft is rotatably connected to the top inner wall and bottom inner wall of the housing through rolling bearings. The bottom end of the third rotating shaft passes through the housing and is fixedly connected to a grinding roller. An annular groove is formed on the upper surface of the base, and the pump body is located inside the annular groove. A clamping mechanism for fixing the pump body is provided inside the base.

[0004] Regarding the aforementioned technologies, two grinding rollers rotate around and uniformly grind the inner and outer walls of the pump body. However, this grinding method can only grind pump bodies of a fixed size and cannot adjust the grinding depth, resulting in low versatility. Utility Model Content

A bolt is inserted into the sliding block and threadedly connected to it. When the bolt abuts against the upper connecting plate, the sliding block is fixed to the upper connecting plate.

[0012] By adopting the above technical solution, rotating the bolt away from the connecting frame allows for adjustment of the connecting frame. The connecting frame then moves the grinding device, and the positions of the outer and inner grinding rollers can be further adjusted according to the specifications of the pump body.

The outer grinding roller 63 is positioned outside the pump body, and the inner grinding roller 65 is positioned inside the pump body. The clamping motor 22 is started, which drives the bidirectional lead screw 21 to rotate. The bidirectional lead screw 21 causes the first clamping block 23 and the second clamping block 24 to move away from or towards each other, thereby clamping the pump body.

[0052] Rotating the bolt away from the connecting bracket 53 adjusts the position of the connecting bracket 53, causing the outer grinding roller 63 to abut against the pump body. Starting the adjusting motor 71 drives the adjusting screw 72 to rotate, which in turn moves the adjusting block 73. The adjusting block 73 then moves the second shaft 64, causing the inner grinding roller 65 to abut against the pump body. The operator adjusts the threaded rod 81 according to the direction of movement of the adjusting block 73. The threaded rod 81 moves the tensioning block 82 within the adjusting groove 5332, which in turn moves the third shaft 66. This ensures that the chain 674 remains engaged with the first sprocket 671, the second sprocket 672, and the third sprocket 673, achieving synchronous movement of the first shaft 62 and the second shaft 64.

[0053] The grinding motor 61 is started, which drives the first shaft 62 to rotate. The first shaft 62 drives the outer grinding roller 63 to move and grind the pump body. The first shaft 62 drives the first sprocket 671 to move. The first sprocket 671 drives the second sprocket 672 to rotate via the chain 674. The second sprocket 672 drives the second shaft 64 to rotate. The second shaft 64 drives the inner grinding roller 65 to move and grind the pump body. The circular track drive device 51 is started, which drives the outer grinding roller 63 and the inner grinding roller 65 to move in a circular motion, thereby achieving the grinding of the pump body.

[0054] Through the cooperation between the horizontal moving mechanism 5, the adjusting component 7 and the tensioning component 8, the equipment can adapt to the grinding of pump bodies of different specifications and can adjust the grinding depth, thereby improving the versatility of the pump body grinding equipment.
