It is usually a cylindrical rod made of metal, which generates pressure waves through reciprocating motion to extract the liquid in the oil well. In order to reduce the surface roughness and friction resistance, thereby improving the working efficiency of the plunger in the pump cylinder, it is usually necessary to grind the surface of the oil well pump plunger during production, so an auxiliary positioning device is needed.

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.

[0023] The movable plates 2 on the left and right sides are driven to move by the electric slide rails installed above the processing table 1, so that the movable plates 2 can drive the mounting shell 5 to move through the support column 4 connected thereto, thereby realizing simple clamping of the two ends of the oil pump plunger, and then the motor 7 fixed inside the mounting shell 5 can be operated to make the rotating disk 8 rotate, and the rotating disk 8 can drive multiple arc rods 3 connected to the outside thereof to move, and the multiple arc rods 3 will drive the slider 10 connected to the other end to move when moving, so that the slider 10 can slide along the guide rod 9, and the guide rod 9 plays a guiding role in the movement of the slider 10, ensuring that the multiple sliders 10 can approach the center when moving, and then the clamping block 12 is driven to approach the center through the externally connected support rod 11, thereby realizing the clamping and fixing operation of the oil pump plunger, fixing it, so that the oil pump plunger will not move during grinding processing, thereby improving the processing accuracy, making the product quality meet the standards, and at the same time improving the production efficiency.

[0024] Reference Figure 2 The collecting component includes a waste hopper 18, which is fixedly connected to the inner top of the processing table 1, and a waste box 20 is fixedly connected to the bottom of the waste hopper 18. The outside of the waste box 20 is fixedly connected to a fan 22 through an exhaust pipe. A filter plate 21 is installed inside the waste hopper 18 near the waste box 20. The fan 22 is fixedly connected to the inner bottom of the processing table 1. A drawer is arranged inside the waste box 20. A partition 19 is fixedly connected to the top of the processing table 1, and the shape of the partition 19 matches the top opening shape of the waste hopper 18.

[0025] Specifically, by starting the fan 22 to generate an airflow, the debris and dust generated by the grinding process can enter the waste hopper 18 below through the partition 19, and the dust and debris are drained by the waste hopper 18 to enter the waste box 20 at the bottom, thereby realizing the collection of debris and dust, making it convenient for workers to take them out through the drawer in the waste box 20 for unified treatment, wherein a filter plate 21 is installed at the bottom of the waste hopper 18 to prevent larger debris from entering the fan 22 and causing damage to it, thereby extending the service life of the equipment.

[0026] Reference Figure 1 The grinding assembly includes a support frame 13, which is fixedly connected to the top rear side of the processing table 1, and a motor 2 14 is fixedly connected to the right side of the outside of the support frame 13, and a threaded rod 15 is fixedly connected to the output end of the motor 2 14, and the external thread of the threaded rod 15 is connected to a threaded block 16, and the front end of the threaded block 16 is fixedly connected to a grinding mechanism 17, and the other end of the threaded rod 15 is rotatably connected to the inside of the support frame 13.

[0027] Specifically, the support frame 13 fixes the motor 2 14, so that the motor 2 14 remains stable during operation and drives the threaded rod 15 to rotate, thereby causing the threaded block 16 to move. Since the top of the threaded block 16 is fixed with a limit block and is slidably connected to the inside of the support frame 13, it can ensure that the threaded block 16 can maintain horizontal movement and drive the grinding mechanism 17 to move to grind the oil pump plunger, thereby improving its surface fineness, reducing surface roughness, and reducing friction resistance.

[0028] Reference Figure 1 The top of the movable plate 2 is connected to the gear 24 via a rotating shaft, and a gear ring 23 is fixedly connected to the outer side of the mounting shell 5 , and the outer side of the gear ring 23 is meshedly connected with the outer side of the gear 24 .

[0029] Specifically, the gear 24 can be rotated by the turning handle, which in turn drives the gear ring 23 to rotate, thereby driving the mounting shell 5 to rotate through the gear ring 23, so that the polished surface of the oil pump plunger can be changed without removing it, thereby improving the processing efficiency. A plug is provided on the outside of the turning handle, so that the gear 24 can be fixed after rotation, thereby ensuring the stability of the mounting shell 5.

[0030] Working principle: When using this device, the oil pump plunger can be placed between the two mounting shells 5, and then the two moving plates 2 can be driven close to each other through the electric slide rail, so that the oil pump plunger is clamped by the two mounting shells 5, and then the rotating disk 8 is driven to rotate by the motor 7 inside the mounting shell 5, so that the multiple arc rods 3 connected to the outside of the rotating disk 8 are moved, and the slider 10 connected to the other end is driven to slide along the guide rod 9, so that the support rod 11 connected to the slider 10 is moved, thereby driving the clamping block 12 to move, so that the multiple clamping blocks 12 are close to the center, so as to clamp and fix the two ends of the oil pump plunger, and ensure that it will not move during the grinding process, which can improve the processing accuracy and the processing quality of the product, and then the gear 24 can be driven to rotate by rotating the handle, and then the gear ring 23 can be driven to rotate, so that the mounting shell 5 is rotated, so as to adjust the grinding surface of the oil pump plunger, so that the grinding surface can be adjusted without removing it, thereby improving the efficiency of the grinding process.

[0031] The operation of the motor 2 14 drives the threaded rod 15 to rotate, thereby causing the threaded block 16 to move, and drives the grinding mechanism 17 to move horizontally, thereby realizing the grinding operation on the surface of the oil pump plunger. The debris generated during grinding will fall into the waste hopper 18 inside the processing table 1 through the partition 19 when the fan 22 is started, and then fall into the waste box 20 after being filtered by the filter plate 21, thereby realizing the collection of debris, reducing the pollution of the environment by the debris generated by grinding, and facilitating the workers to uniformly handle it.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
