Description

Technical Field

[0001] This utility model relates to the field of mechanical seal technology, and in particular to a polishing device for annular seals. Background Technology

[0002] Annular seals are the core components of mechanical seals, mainly consisting of stationary and rotating rings. The end faces of the stationary and rotating rings form a sealing structure that moves relatively but is in close contact, preventing axial leakage. Therefore, the surface finish of the end faces of annular seals is required to be high.

[0003] During the processing of the end face of annular seals, a polishing cloth can be used for rotary polishing to ensure a smooth finish. The polishing cloth can be glued to a turntable, making operation simple; the turntable drives the cloth's rotation. However, disassembly is difficult, and damaged cloths require scraping off the glue with a scraper, affecting the ease of cloth replacement and reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a polishing device for annular seals, which facilitates the clamping and disassembly of polishing cloth and improves production efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution: A polishing device for annular seals includes: a tank, a clamp, a motor, a lifting seat, and an annular polishing cloth. A first support is provided in the tank. The clamp is horizontally mounted on the first support for positioning and clamping the annular seal. The lifting seat is suspended above the clamp. The motor is vertically mounted at the bottom of the lifting seat. A turntable concentric with the annular seal is provided at the bottom of the motor shaft. A downward-pointing guide post is concentrically provided at the bottom of the turntable. The annular polishing cloth is concentrically fitted onto the guide post. The top surface of the annular polishing cloth is in contact with the bottom surface of the turntable. A threaded sleeve is provided on the outer circumference of the turntable. A pressure ring for pressing the edge of the annular polishing cloth is provided at the bottom of the threaded sleeve.

[0006] The clamp is a three-jaw chuck.

[0007] The tank has a second support extending to the top of the tank on one side, and an electric screw slide table that drives the lifting seat to move up and down is provided on the second support.

[0008] The threaded sleeve and the pressure ring are made of an integrated steel structure.

[0009] The turntable has an external thread on its outer circumference that corresponds to the threaded sleeve.

[0010] The inner diameter of the pressure ring is larger than the outer diameter of the annular seal.

[0011] The outer diameter of the guide post is smaller than the inner diameter of the annular seal.

[0012] The beneficial effects of this utility model are as follows: A polishing device for annular seals fixes the annular seals on a fixture, uses a turntable to drive the rotation and downward pressure of the annular polishing cloth, and uses the contact between the annular polishing cloth and the end face of the annular seal to achieve polishing treatment of the end face of the annular seal. The annular polishing cloth can be centered by a guide post and edge-pressed by a pressure ring. The structure is stable, and the disassembly and replacement are relatively quick, which is conducive to the rapid resumption of production and improves the production efficiency of annular seal polishing treatment. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 yes Figure 1 A magnified view of part A in the middle. Detailed Implementation

[0014] The following is combined with Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0015] like Figure 1 and Figure 2 The annular seal polishing device shown is used for polishing the end face of the annular seal 12. It includes: a groove 1, a clamp 7, a motor 5, a lifting seat 4, and an annular polishing cloth 11. A first support 6 is provided in the groove 1, which can be fixed with screws, resulting in a stable structure. The groove 1 can be made of stainless steel with a cuboid structure and an opening at the top, which provides good durability.

[0016] The clamp 7 is horizontally mounted on the first bracket 6 to position and clamp the annular seal 12. In this embodiment, the clamp 7 is a three-jaw chuck, which is easy to operate and has good adaptability to the outer diameter of the annular seal 12.

[0017] The lifting seat 4 is suspended above the clamp 7. A second bracket 2 extending to the top of the groove 1 is provided on one side of the groove 1. An electric screw slide 3 that drives the lifting seat 4 to move up and down is provided on the second bracket 2. The electric screw slide 3 can be extended and retracted by a PLC controller to drive the lifting seat 4 to adjust its height.

[0018] The motor 5 is vertically mounted at the bottom of the lifting base 4 and can be fixed with screws, so that the motor 5 moves up and down with the lifting base 4. The bottom of the rotating shaft of the motor 5 is provided with a turntable 8 concentric with the annular seal 12. The bottom of the turntable 8 is concentrically provided with a downward-pointing guide post 13. The annular polishing cloth 11 is concentrically fitted on the guide post 13, and the guide post 13 cooperates with the center hole of the annular polishing cloth 11 to center the annular polishing cloth 11.

[0019] The outer diameter of the guide post 13 is smaller than the inner diameter of the annular seal 12. The guide post 13 rotates and moves downward with the turntable 8. During the downward movement, the guide post 13 enters the inner hole of the annular seal 12, thus avoiding the problem of the guide post 13 hitting the annular seal 12.

[0020] like Figure 2 As shown, the top surface of the annular polishing cloth 11 is in contact with the bottom surface of the turntable 8. A screw sleeve 9 is provided on the outer circle of the turntable 8, and an external thread corresponding to the screw sleeve 9 is provided on the outer circle of the turntable 8, making disassembly and assembly relatively convenient.

[0021] The bottom of the screw sleeve 9 is provided with a pressure ring 10 for pressing the edge of the annular polishing cloth 11. In this embodiment, the screw sleeve 9 and the pressure ring 10 adopt an integrated steel structure with high strength. The pressure ring 10 is rotated and moved axially by the screw sleeve 9 to press the edge of the annular polishing cloth 11. The structure is stable and easy to disassemble and replace, which helps to improve maintenance convenience and production efficiency.

[0022] like Figure 1 As shown, the inner diameter of the pressure ring 10 is larger than the outer diameter of the annular seal 12, which does not affect the downward movement of the pressure ring 10, so that the top end face of the annular seal 12 contacts the annular polishing cloth 11, and the annular seal 12 end face is polished by rotating the annular polishing cloth 11.

[0023] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
