Technical Field

[0001] The utility model belongs to the technical field of pump body processing, in particular to a pump body grinding device. Background Art

[0002] The pump is mainly composed of a pump body, a pump cover, an impeller, a pump shaft, etc. The pump body, as the core component, is generally made of metal casting. Its casting accuracy and quality directly affect the performance of the entire pump. During the casting process, due to defects in the mold and lack of casting technology, burrs are easily generated on the pump body, affecting the equipment and use. Therefore, the pump body needs to be polished and cleaned to improve the surface quality of the pump body. Therefore, it is particularly important to polish and clean the flash burrs remaining after casting.

[0003] In the prior art, pump body grinding technology is usually performed by mechanical automation or semi-automatic equipment to perform grinding and deburring operations, which is usually composed of a base, a robotic arm, a clamp, a drill bit, and a control console. Through the path set by the console, the robotic arm uses the drill bit at the end to grind the pump body at different angles.

[0004] In the prior art, due to the complex shape of the pump body, the automated grinding equipment for deburring such complex parts is not widely used in the market. When the pump body is too complicated, the drill bit needs to be replaced frequently, which leads to low grinding efficiency. Moreover, due to the complexity of the pump body, the drill bit will be in a high temperature state for a long time during operation, which causes great wear on the drill bit itself. Therefore, a pump body grinding device is proposed to address the above problems. Utility Model Content

[0023] During operation, in the process of pump body processing, when the pump body is too complicated, the drill bit needs to be replaced frequently, which results in short effective working time and low grinding efficiency. In addition, due to the complexity of the pump body, the drill bit will be in a high temperature state for a long time during operation, which causes great wear on the drill bit itself. Therefore, a pump body grinding device is proposed to address the above problems. When the pump body is ground, the shaft of the motor 23 rotates, which will drive the shaft 20 installed at the end of the mechanical arm 14 to rotate synchronously, and the drill rod 28 is connected to the shaft 20 through a connecting piece 26. When the shaft 20 rotates, the drill rod 28 also rotates synchronously, and the drill disc 30 installed under the drill rod also rotates synchronously. A lifter 13 is installed at the connection between the shaft 20 and the mechanical arm 14 above the shaft 20. When the shaft 20 rotates, the lifter 13 will rotate synchronously. Through the operation of the lifting base 16, the overall height of the drill bit will change accordingly, and the rotation of the mechanical arm 14 is controlled by the console to complete the grinding operation of the pump body.

[0024] Furthermore, two groups of slide rails 7 are fixedly installed on both sides of the base 1, and sliders 9 are movably installed on the surfaces of the slide rails 7. A fixed bracket 10 is fixedly installed above the slider 9. The two groups of fixed brackets 10 are rotatably connected through a movable shaft 11. A bearing 17 is installed on the contact surface of the movable shaft 11 and the fixed bracket 10. The movable shaft 11 passes through the workbench 6 for rotatable installation. The contact surface of the workbench 6 and the movable shaft 11 is installed with a bearing 17. A clamp 21 is fixedly installed on the surface of the workbench 6, and two groups of taps 22 are fixedly installed on the top of the clamp 21. A lead screw 8 is installed through the bottom of the workbench 6, and a lead screw slider 19 is installed on the circumferential surface of the lead screw 8. Slots are opened on both sides of the base 1, and a rotating handle 18 is rotatably installed in the middle of the slot. The lead screw 8 passes through the base 1 horizontally, and the two side ends of the lead screw 8 are rotatably connected to the rotating handle 18.

[0025] During operation, the pump body to be polished is placed on the surface of the workbench 6 and fixed by the clamp 21. The sliders 9 on both sides are moved to drive the moving shaft 11 to move, and the workbench 6 will move synchronously with the moving shaft 11. By rotating the handle 18 in the middle of the rotating base 1, the screw slider 19 will move horizontally, and at the same time, it will drive the upper workbench 6 to move horizontally, so as to cooperate with the upper mechanical arm 14 to polish the pump body.

[0026] Furthermore, a water reservoir 4 is fixedly installed in the middle of the base 1, a filter screen 5 is arranged above the water reservoir 4, four sets of universal wheels 3 are rotatably installed at the bottom of the base 1, a foot brake 2 is fixedly installed between the universal wheels 3 and the bottom, a water outlet 61 is fixedly installed on the surface of the workbench 6, and a water pump is installed inside the workbench 6.

[0027] During operation, long-term grinding work will cause the drill bit to be in a high temperature state. The drill bit 29 is cooled down through the water outlet 61 arranged on the surface of the workbench 6, and then the water flows into the water reservoir 4 together with the grinding waste. The waste will be blocked by the filter net 5 arranged on the surface of the water reservoir 4, which is convenient for subsequent cleaning of the equipment.

[0028] Working principle: During the processing of the pump body, when the pump body is too complicated, the drill bit needs to be replaced frequently, which results in a short effective working time and low grinding efficiency. In addition, due to the complexity of the pump body, the drill bit will be in a high temperature state for a long time during operation, which causes great wear on the drill bit itself. Therefore, a pump body grinding device is proposed to address the above problems. When the pump body is ground, the shaft of the motor 23 rotates, which will drive the shaft 20 installed at the end of the mechanical arm 14 to rotate synchronously, and the drill rod 28 is connected to the shaft 20 through a connecting piece 26. When the shaft 20 rotates, the drill rod 28 also rotates synchronously, and the drill disc 30 installed under the drill rod also rotates synchronously. A lifter 13 is installed at the connection between the shaft 20 and the mechanical arm 14 above the shaft 20. When the shaft 20 rotates, the lifter 13 will rotate synchronously. Through the operation of the lifting base 16, the overall height of the drill bit will change accordingly, and the rotation of the mechanical arm 14 is controlled by the console to complete the grinding operation of the pump body. Place the pump body to be polished on the surface of the workbench 6 and fix it with the clamp 21. Move the sliders 9 on both sides to drive the moving shaft 11 to move. The workbench 6 will move synchronously with the moving shaft 11. By rotating the handle 18 in the middle of the base 1, the lead screw slider 19 will move horizontally, and at the same time, it will drive the upper workbench 6 to move horizontally to cooperate with the upper mechanical arm 14 to polish the pump body. Long-term polishing will cause the drill bit to be in a high temperature state. The drill bit 29 is cooled by the water outlet 61 set on the surface of the workbench 6. Then the water and the polished waste will flow into the water reservoir 4. The waste will be blocked by the filter 5 set on the surface of the water reservoir 4, which is convenient for subsequent cleaning of the equipment.
