Description

Technical Field

[0001] This utility model relates to the field of plunger processing technology, specifically to a clamping device for processing the plunger body of an oil pump. Background Technology

[0002] A pumping unit is a common downhole device that uses a pumping unit to pump crude oil from a well to the surface. A typical pumping unit mainly consists of four parts: the pump barrel, the suction valve, the piston, and the discharge valve. Based on how the pumping unit is fixed downhole, it can be divided into tubular pumps and rod pumps. The pumping unit's plunger is a crucial component; it is in direct contact with the pump barrel, and the two are slidably connected. If the outer wall of the plunger is not smooth and has protrusions, it can severely scratch the inner wall of the pump barrel. Therefore, the outer wall of the plunger needs to be ground and polished.

[0003] In the process of realizing this utility model, the inventors discovered the following unresolved problems in the prior art: Although the existing oil pump plunger body machining clamping device has a clamping mechanism that does not cover the plunger to prevent the clamping area from being unable to be ground, the plunger body not only needs to be ground on the arc surface, but also, according to customer requirements, the side end faces at both ends need to be ground, especially if there are burrs. In this case, the middle part of the plunger needs to be clamped and then both ends need to be ground, which involves many steps, is time-consuming and labor-intensive, and is not practical. It is urgent to improve it. Therefore, we propose an oil pump plunger body machining clamping device. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device for machining the plunger body of an oil pump, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for machining the plunger body of an oil pump, comprising a base plate, on both sides of the upper surface of the base plate being fixedly installed with support platforms, and a limit rod being placed at the top between the support platforms;

[0006] One end of the limiting rod is rotatably connected to the support platform via a hinge, and the other end of the limiting rod is fixedly installed with a limiting block. A screw rod is movably passed through the center of the limiting block, and the bottom end of the screw rod is screwed to a pre-set screw hole on the support platform via an external thread.

[0007] A reinforcing rib is fixedly installed on the outer side of the connection between the support platform and the base plate, and the reinforcing rib has a triangular structure.

[0008] A plunger body is sleeved on the outer side of the middle part of the limiting rod, and stainless steel hollow blocks are fixedly installed on both sides of the limiting rod near the plunger body.

[0009] Both sides of the stainless steel hollow block are provided with arc-shaped plates. Anti-slip pads are fixedly installed on the outer side of the arc-shaped plates and abut against the inner wall of the plunger body. It can be used in conjunction with components such as the limiting rod, the stainless steel hollow block and the limiting block. During the use of the clamping device, the screw can be removed and the limiting rod can be tilted and lifted so that the plunger is sleeved on the outer side of the limiting rod and clamped and limited by the arc-shaped plates of the stainless steel hollow block. Then the screw can be reinstalled to limit it. At this time, there are enough operation steps between the two sides of the plunger and the support platform. After the plunger arc surface is polished, the side end face can be polished or the burrs can be removed without adjustment. Compared with the existing method, the overall polishing efficiency is improved.

[0010] As an optional solution to the technical solution of this application, a movable rod is fixedly installed on the inner side of the arc-shaped plate, and a strong electromagnet is fixedly installed at the inner end of the movable rod. Iron blocks are fixedly installed on both the top and bottom sides of the stainless steel hollow block. The strong electromagnet and iron blocks can be used together. Since the stainless steel hollow block is not magnetic, whenever the strong electromagnet is turned on, the strong electromagnet moves and strongly attracts and positions itself on the iron block, so that the arc-shaped plate is pressed against the inner wall of the plunger. Conversely, when the strong electromagnet is turned off, the plunger can be pulled away, so that the limiting structure has a convenient disassembly and assembly effect, further improving processing efficiency and achieving a more ideal effect.

[0011] As an optional solution to the technical solution of this application, a battery is fixedly installed on the front wall of a set of support platforms, and the battery is electrically connected to a strong electromagnet through a wire. Power can be supplied by the battery, so there is no need to pull an excessively long wire, which indirectly facilitates the relocation and use in the future.

[0012] As an optional solution to the technical solution of this application, the stainless steel hollow block has a wire opening on its side wall and a wire hole in the limiting rod. The wire opening and the wire hole are connected and configured to communicate with each other. Through the cooperation of the wire opening and the wire hole, internal wiring can be realized, which not only has the function of cable protection, but also facilitates grinding operations.

[0013] As an optional solution to the technical solution of this application, a set of the support platform front wall is fixedly installed with an indicator sign, and the indicator sign is fixed by welding. The guide text on the indicator sign can inform the operator of the corresponding procedures, so as to facilitate understanding of the product and smooth use.

[0014] As an optional solution to the technical solution of this application, ear plates are fixedly installed on both sides of the base plate, and a positioning hole is opened in the middle of the ear plate. The positioning bolt can be passed through the positioning hole of the ear plate and screwed into the pre-set thread structure on the support, so as to realize the detachable and stable positioning of the device.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model discloses a clamping device for machining the plunger body of an oil pump. By setting a limit rod, a stainless steel hollow block, and a limit block, during the use of the clamping device, the screw can be removed and the limit rod can be tilted and lifted so that the plunger is sleeved on the outside of the limit rod and clamped and limited by the arc plate of the stainless steel hollow block. Then, the screw can be reinstalled to limit it. At this time, there are enough operating steps between the two sides of the plunger and the support platform. After the plunger arc surface is ground, the side end face can be ground or the burrs can be removed without adjustment. Compared with the existing method, the overall grinding efficiency is improved.

[0017] 2. This utility model relates to a clamping device for machining the body of an oil pump plunger. By setting up a strong electromagnet and an iron block, since the stainless steel hollow block is non-magnetic, whenever the strong electromagnet is turned on, the strong electromagnet moves and strongly attracts and positions itself on the iron block, so that the arc-shaped plate is pressed against the inner wall of the plunger. Conversely, when the strong electromagnet is turned off, the plunger can be pulled away. This makes the limiting structure easy to disassemble and assemble, further improving the machining efficiency and achieving a more ideal effect. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-3This utility model provides a technical solution: a clamping device for machining the plunger body of an oil pump, including a base plate 1. Ear plates 11 are fixedly installed on both sides of the base plate 1, and a positioning hole is provided in the center of each ear plate 11. A positioning bolt passes through the positioning hole of the ear plate 11 and is screwed onto a pre-set threaded structure on a support, enabling the device to be detachable and stably positioned. Supports 2 are fixedly installed on both sides of the upper surface of the base plate 1, and a limiting rod 3 is placed on the top between the supports 2. One end of the limiting rod 3 is rotatably connected to the support 2 via a hinge 31, and the other end of the limiting rod 3 is fixedly installed with a limiting block 32. A screw 33 is movably passed through the center of the limiting block 32, and the bottom end of the screw 33 is screwed onto a pre-set screw hole on the support 2 via an external thread. A reinforcing rib 12 is fixedly installed on the outer side of the connection between the support 2 and the base plate 1, and the reinforcing rib 12 is triangular. The structure includes a support platform 2 with an indicator sign 21 fixedly installed on the front wall. The indicator sign 21 is fixed by welding and can guide the operator to the corresponding procedures through the guiding text on the indicator sign 21, making it easy to understand the product and use it smoothly. A plunger body 4 is sleeved on the outer side of the middle of the limiting rod 3. Stainless steel hollow blocks 5 are fixedly installed on both sides of the limiting rod 3 near the plunger body 4. The side wall of the stainless steel hollow block 5 has a wire opening 56, and the limiting rod 3 has a wire hole 34. The wire opening 56 and the wire hole 34 are connected and set. Through the cooperation of the wire opening 56 and the wire hole 34, internal wiring can be realized, which not only has the function of cable protection, but also facilitates grinding operation. Arc plates 54 are set on both sides of the stainless steel hollow block 5. Anti-slip pads 53 are fixedly installed on the outer side of the arc plates 54 and the anti-slip pads 53 abut against the inner wall of the plunger body 4.

[0025] In this technical solution, components such as the limiting rod 3, the stainless steel hollow block 5, and the limiting block 32 can be used together. During the use of the clamping device, the screw 33 can be removed and the limiting rod 3 can be tilted and lifted so that the plunger is sleeved on the outside of the limiting rod 3 and clamped and limited by the arc plate 54 of the stainless steel hollow block 5. Then the screw 33 can be reinstalled to limit it. At this time, there are enough operating procedures between the two sides of the plunger and the support platform 2. After the plunger arc surface is polished, the side end face can be polished or the burrs can be removed without adjustment. Compared with the existing method, the overall polishing efficiency is improved.

[0026] In some technical solutions, a movable rod 52 is fixedly installed on the inner side of the arc plate 54, and a strong electromagnet 51 is fixedly installed at the inner end of the movable rod 52. Iron blocks 55 are fixedly installed on both the top and bottom sides of the stainless steel hollow block 5. A battery 22 is fixedly installed on the front wall of a set of support platforms 2, and the battery 22 is electrically connected to the strong electromagnet 51 through a wire. It can be powered by the battery 22, so there is no need to pull an excessively long wire, which indirectly facilitates the later relocation and use.

[0027] In this technical solution, components such as a strong electromagnet 51 and an iron block 55 can be used together. Since the stainless steel hollow block 5 is not magnetic, whenever the strong electromagnet 51 is turned on, the strong electromagnet 51 moves and strongly attracts and positions itself on the iron block 55, so that the arc plate 54 is pressed against the inner wall of the plunger. Conversely, when the strong electromagnet 51 is turned off, the plunger can be pulled away, so that the limiting structure has a convenient disassembly and assembly effect, further improving processing efficiency and achieving a more ideal effect.

[0028] Working principle: It should be noted that this utility model is a clamping device for processing the plunger body of an oil pump. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0029] When a processing clamping device for a pump plunger body is used, the processing clamping device is transported to the processing area such as the pump plunger body grinding, and then fixed by the ear plate 11, so that the plunger body 4 is sleeved and fixed on the outside of the limit rod 3, and the personnel hold the grinding tool to perform grinding operations.

[0030] By setting a limiting rod 3, a stainless steel hollow block 5, and a limiting block 32, during the use of the clamping device, the screw 33 can be disassembled and the limiting rod 3 tilted and lifted, so that the plunger is sleeved on the outside of the limiting rod 3 and clamped and limited by the arc plate 54 of the stainless steel hollow block 5. Then, the screw 33 can be reinstalled to limit it. At this time, there are enough operating procedures between the two sides of the plunger and the support platform 2. After the plunger arc surface is polished, the side end face can be polished or the burrs can be removed without adjustment. Compared with the existing method, the overall polishing efficiency is improved. By setting a strong electromagnet 51 and an iron block 55, since the stainless steel hollow block 5 is not magnetic, whenever the strong electromagnet 51 is turned on, the strong electromagnet 51 moves and strongly attracts and positions itself on the iron block 55, so that the arc plate 54 is pressed against the inner wall of the plunger. Conversely, when the strong electromagnet 51 is turned off, the plunger can be pulled away, so that the limiting structure has a convenient disassembly and assembly effect, further improving the processing efficiency and the use effect is quite ideal.
