Description

Technical Field

[0001] The utility model relates to the technical field of plunger pump processing, in particular to a plunger pump hole opening and grinding device. Background Technique

[0002] A plunger pump is a pump that uses a plunger to reciprocate in the pump body to achieve liquid transportation. It pumps the liquid from the suction end of the pump to the discharge end through the reciprocating movement of the plunger in the pump cylinder. The plunger pump has a high pressure output capacity and flow control accuracy, and is widely used in occasions that require high-pressure liquid transportation, such as hydraulic systems, petrochemical industries, pharmaceutical industries, etc. When processing a plunger pump, a hole opening and grinding device can ensure that the hole positions and surfaces of each part meet the design requirements. Good surface treatment and precise processing can improve the wear resistance of the pump, reduce damage caused by friction and corrosion, and thus extend the service life of the pump.

[0003] When using traditional partial plunger pump hole opening and grinding devices, the plunger pump is placed on the surface of the workbench. Subsequently, by rotating the screw, the clamping plate is driven to move to fix the plunger pump to ensure the stability of the processing process. Then, a grinding device is used for processing. However, this method of moving the clamping plate by rotating the screw to fix the plunger pump does not consider relatively troublesome problems. Therefore, a plunger pump hole opening and grinding device is proposed to solve the above problems. Summary of the Invention

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 2, an embodiment provided by the present utility model: a hole-opening and grinding device for a plunger pump, including a base 1, a placing table 2 fixedly connected to the top of the base 1, a first motor 3 fixedly connected to the top of the base 1, a rotating plate 4 fixedly connected to the output end of the first motor 3, an L-shaped plate 5 rotatably connected to the bottom of the rotating plate 4, a chute 6 opened inside the placing table 2, a slider 7 arranged inside the placing table 2, the slider 7 slidingly connected inside the chute 6, a fixing block 8 fixedly connected to the bottom of the slider 7, one side of the L-shaped plate 5 rotatably connected to the side wall of the fixing block 8, a clamping plate 9 fixedly connected to the top of the slider 7, and an auxiliary component arranged on the side wall of the clamping plate 9 for preventing the clamping plate 9 from directly contacting the plunger pump. A fixing cover 11 is fixedly connected to the top of the base 1, and a processing component is arranged on the side wall of the fixing cover 11 for grinding the plunger pump. The auxiliary component includes a rubber pad 10, and the side wall of the rubber pad 10 is fixedly connected to the opposite sides of the clamping plate 9. The processing component includes a hydraulic rod 12, the hydraulic rod 12 fixedly connected inside the fixing cover 11, a fixing plate 13 fixedly connected to the output end of the hydraulic rod 12, a second motor 14 fixedly connected to the top of the fixing plate 13, and a grinding rod 15 fixedly connected to the output end of the second motor 14;

[0032] When using this device for work, place the plunger pump to be processed on the surface of the placing table 2. After placing, start the first motor 3, and the first motor 3 will drive the rotating plate 4 to rotate. As the rotating plate 4 continues to rotate, one side of the L-shaped plate 5 will move together with the rotating plate 4. At the same time, the other side of the L-shaped plate 5 will rotate on the fixing block 8 and pull the slider 7 to move. The slider 7 will slide towards the center inside the chute 6, making the clamping plate 9 gradually approach the plunger pump until the rubber pad 10 is tightly attached to the outer wall of the plunger pump, thus achieving the effect of quickly fixing the plunger pump. After fixing, start the hydraulic rod 12, and the hydraulic rod 12 will drive the fixing plate 13 to move downward. At the same time, start the second motor 14, and the second motor 14 will drive the grinding rod 15 to rotate. The grinding rod 15 will grind the plunger pump during the rotation process, thus completing the entire processing process.

[0033] Referring to Figure 3 - Figure 4 , a fixing box 16 is fixedly connected inside the base 1, a collecting box 17 is slidably connected inside the fixing box 16, a partition net 22 is fixedly connected inside the collecting box 17, a blower 25 is arranged on the side wall of the fixing box 16, a side plate 18 is rotatably connected to the side wall of the fixing box 16, a sliding rod 19 is slidably connected inside the side plate 18, the side wall of the sliding rod 19 is slidably connected inside the collecting box 17, a fixing ring 21 is fixedly connected to the side wall of the sliding rod 19, a spring 20 is sleeved on the side wall of the sliding rod 19, one end of the spring 20 is fixedly connected to the side wall of the side plate 18, the other end of the spring 20 is fixedly connected to the side wall of the fixing ring 21, a dust suction pipe 23 is fixedly connected inside the fixing box 16, the side wall of the dust suction pipe 23 penetrates through the side wall of the base 1 and is fixedly connected to a dust suction cover 24, and the side wall of the dust suction cover 24 is fixedly connected inside the fixing cover 11.

[0034] During the grinding process, the blower 25 can be started, and the suction pipe 23 and the suction hood 24 are used to extract the dust generated during grinding. The partition net 22 arranged inside the collection box 17 can effectively block and collect the dust inside the collection box 17. After the grinding work is completed, the sliding rod 19 can be pulled through the fixing ring 21 to move it out from inside the collection box 17. Then, the side plate 18 is deflected to remove the restriction on the collection box 17. At this time, the collection box 17 can be pulled out from inside the fixed box 16 to facilitate the cleaning of the collected dust. After the cleaning work is completed, the collection box 17 is pushed back into the fixed box 16 again. Then, the fixing ring 21 is pulled again to make the sliding rod 19 slide and cause the spring 20 to deform. The side plate 18 is deflected to align the sliding rod 19 with the concave hole inside the collection box 17. At this time, the fixing ring 21 is released, and the spring 20 will reset under the loss of pressure, thereby inserting the sliding rod 19 into the collection box 17 to fix the collection box 17 and ensure that the collection box 17 is completely placed inside the fixed box 16 and the stability during placement.

[0035] Working principle: When using this equipment for work, first place the plunger pump to be processed on the surface of the placement table 2, and then start the first motor 3 to drive the rotating plate 4 to rotate. As the rotating plate 4 rotates, one side of the L-shaped plate 5 will move along with the rotating plate 4, and the other side of the L-shaped plate 5 will rotate on the fixed block 8 while pulling the slider 7 to move. The slider 7 will slide inward in the chute 6, and the clamping plate 9 will gradually approach the plunger pump until the rubber pad 10 is in contact with the outer wall of the plunger pump, achieving the effect of quickly fixing the plunger pump. After the fixing is completed, the hydraulic rod 12 is started to drive the fixing plate 13 to move downward, and the second motor 14 is started to drive the grinding rod 15 to rotate to perform the grinding work on the plunger pump;

[0036] During the grinding process, the blower 25 can be started, and the suction pipe 23 and the suction hood 24 are used to extract the dust generated by grinding. The partition net 22 inside the collection box 17 will block the dust inside the collection box 17 for collection. After the work is completed, the sliding rod 19 can be pulled through the fixing ring 21 to move it out from inside the collection box 17. Then, the side plate 18 is deflected to remove the restriction on the collection box 17. At this time, it is pulled out from inside the fixed box 16 to clean the collected dust. After the cleaning is completed, the collection box 17 is pushed back into the fixed box 16. Then, the fixing ring 21 is pulled again to make the sliding rod 19 slide and cause the spring 20 to deform. The side plate 18 is deflected to align the sliding rod 19 with the concave hole inside the collection box 17. At this time, the fixing ring 21 is released, and the spring 20 will reset under the loss of pressure, thereby inserting the sliding rod 19 into the collection box 17 to fix the collection box 17 and ensure that the collection box 17 is completely placed inside the fixed box 16, ensuring the stability of the placement of the collection box 17.
