Description

Technical Field

[0001] This utility model relates to the field of piston seal ring processing technology, specifically a piston seal ring processing device. Background Technology

[0002] Currently, piston structures are used in all aspects of life, work, and manufacturing. A wide variety of piston-structured products are available on the market, each with its own design philosophy, striving to meet the diverse requirements of different users. Piston seals, with their advantages of simple structure and reliable performance, are widely used in hydraulic systems of mechanical equipment, becoming crucial components for sealing reciprocating motion parts and rotating shafts. The machining methods for piston seals include turning.

[0003] This is the most mainstream method for producing PTFE seals (such as guide rings, retaining rings, step seals, etc.). The blank pipe is clamped on a lathe, and diamond or carbide cutting tools are used to precisely cut the inner diameter, outer diameter, and end face of the pipe according to the program. The required cross-sectional shape of the seal (such as rectangle, triangle, special groove, etc.) is directly machined, and a perfect seal is obtained by cutting. However, since the raw material of the seal is a soft tubular structure, the lathe fixture is prone to deformation during the clamping process of the seal material, resulting in poor stability of the seal processing and clamping. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the above-mentioned problems and the existing problems in piston seal processing devices, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a piston sealing ring processing device. When processing the sealing ring material, the slider moves outward in the groove to fix the inner wall of the sealing ring material, which facilitates the clamping and fixing of the piston sealing ring and avoids the piston sealing ring material from being squeezed and deformed.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A piston seal processing apparatus, comprising: The mounting component has grooves arranged in a ring on its outer wall, and mounting holes communicating with the grooves are provided on its side wall. Each of the grooves contains a slider, and each slider has a tapered groove on its inner wall. An internal hexagonal screw is adjustablely installed in the mounting hole, and a protrusion for pushing the slider is welded to the outer wall of the internal hexagonal screw. The sealing ring material is slidably sleeved on the mounting part, and the multiple sliders abut against the inner wall of the sealing ring material; The clamping assembly includes mounting portions fixed at both ends of the mounting member, each of the two mounting portions having a groove, and a pressure plate for clamping and fixing the outer wall of the sealing ring material is slidably disposed in the groove; A lathe clamping assembly includes a connector and a threaded component integrally formed on the connector, the threaded component being fixed to a mounting component.

[0012] In a preferred embodiment of the piston seal ring processing device of this utility model, the outer wall of the mounting component is integrally formed with a clamping component, and the mounting part is fixed at both ends of the clamping component.

[0013] In a preferred embodiment of the piston seal ring processing device of this utility model, a knob bolt is threaded into the side wall of the mounting part, and one end of the knob bolt extending into the groove is rotatably engaged in the pressure plate.

[0014] In a preferred embodiment of the piston seal ring processing device of this utility model, both pressure plates protrude from the side wall of the mounting part, and the inner walls of both pressure plates are arc-shaped to match the outer wall of the seal ring material.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When processing the sealing ring material, the sealing ring material is fitted onto the mounting part, and the internal hexagonal screw is tightened and inserted into the second threaded hole. During the movement of the internal hexagonal screw, the protrusion is driven to squeeze the conical groove, causing the slider to move outward in the groove to fix the inner wall of the sealing ring material.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] This utility model provides a piston sealing ring processing device. When processing the sealing ring raw material 400, the slider 102 moves outward in the groove 107 to fix the inner wall of the sealing ring raw material 400, which facilitates the clamping and fixing of the piston sealing ring and avoids the piston sealing ring raw material 400 from being squeezed and deformed.

[0022] Figure 1 - Figure 6 The diagram shown is an overall structural schematic of one embodiment of the piston seal ring processing device of this utility model. Please refer to [link / reference]. Figure 1 - Figure 6 This embodiment of a piston seal ring processing apparatus includes: Mounting component 100 has grooves 107 arranged in a ring on its outer wall, and mounting holes 103 communicating with the grooves 107 on its side wall. Each groove 107 contains a slider 102, and each slider 102 has a tapered groove 108 on its inner wall. An internal hexagonal screw 101 is adjustablely mounted in each mounting hole 103. The outer wall of the internal hexagonal screw 101 is welded with a protrusion for pushing the sliders 102. Specifically, in this embodiment, the sealing ring material 400 is matched with the mounting part 100. The sealing ring material 400 is sleeved on the mounting part 100. The internal hexagon screw 101 is tightened by a hexagon wrench and inserted into the second threaded hole 105. During the movement of the internal hexagon screw 101, the protrusion 106 is driven to squeeze the conical groove 108, so that the slider 102 moves to the outside of the mounting part 100 in the groove 107 to fix the inner wall of the sealing ring material 400. The sealing ring material 400 is slidably sleeved on the mounting part 100, and multiple sliders 102 abut against the inner wall of the sealing ring material 400. The clamping assembly includes mounting portions 201 fixed at both ends of the mounting member 100. Each mounting portion 201 has a groove 202. A pressure plate 203 for clamping and fixing the outer wall of the sealing ring material 400 is slidably disposed in the groove 202. The lathe clamping assembly includes a connector 300 and a threaded part 301 integrally formed on the connector 300. The threaded part 301 is fixed to the mounting part 100. Specifically, in this embodiment, after the knob bolt 204 is tightened, it drives the pressure plate 203 to fix the outer wall of the sealing ring material 400. The mounting part 100 can prevent the sealing ring material 400 from being squeezed and deformed.

[0023] Combination Figure 1 - Figure 6 The piston seal ring processing device of this embodiment is used in the following specific process: When processing the seal ring raw material 400, the seal ring raw material 400 is sleeved on the mounting part 100, and the internal hexagon screw 101 is tightened, so that the internal hexagon screw 101 moves into the second threaded hole 105. During the movement of the internal hexagon screw 101, the protrusion 106 is driven to slide synchronously in the mounting hole 103. The protrusion 106 presses the tapered groove 108, so that the slider 102 moves to the outside of the mounting part 100 in the sliding groove 107. During the movement, the slider 102 makes contact with the seal ring. The inner wall of the sealing ring material 400 is tightly connected, keeping the sealing ring material 400 fixed on the mounting part 100. Tightening the knob bolt 204 causes the pressure plate 203 to move in the groove 202. The pressure plate 203 presses and fixes the outer wall of the sealing ring material 400. The mounting part 100 can prevent the sealing ring material 400 from being deformed by compression. At the same time, the connecting part 300 on the mounting part 100 is used to clamp and fix it on the lathe, which facilitates the clamping and fixing of the piston sealing ring during processing and avoids the piston sealing ring material 400 from being squeezed and deformed.

[0024] In this embodiment, the inner wall of the mounting hole 103 is provided with a second threaded hole 105, and the internal hexagon screw 101 is threaded into the second threaded hole 105. The end of the mounting member 100 away from the internal hexagon screw 101 is provided with a first threaded hole 104, and the threaded part 301 is threaded into the first threaded hole 104. The inner walls of the multiple sliders 102 are all protruding in the mounting hole 103. A tapered groove 108 is provided at the protruding end of the slider 102. The protrusion 106 has a tapered structure, and the outer wall of the protrusion 106 matches the tapered groove 108. When the connector 300 is in use, the threaded part 301 on it is threaded into the first threaded hole. The tightening direction of the threaded part 301 is the same as the rotation direction of the lathe. Therefore, when the sealing ring material 400 on the mounting member 100 is rotated, the connector 300 will not separate from the mounting member 100.

[0025] Therefore, please refer to again Figure 1- Figure 6 In this embodiment, the outer wall of the mounting component 100 is integrally formed with a clamping component 200. The mounting part 201 is fixed at both ends of the clamping component 200. A knob bolt 204 is threaded into the side wall of the mounting part 201. One end of the knob bolt 204 extends into the groove 202 and is rotated and engaged in the pressure plate 203. Both pressure plates 203 are protruding from the side wall of the mounting part 201, and the inner walls of both pressure plates 203 are arc-shaped and match the outer wall of the sealing ring material 400. After the knob bolt 204 is tightened, it drives the pressure plate 203 to fix the outer wall of the sealing ring material 400. The mounting component 100 can prevent the sealing ring material 400 from being deformed by compression.
