Description

Technical Field

[0001] This invention relates to the field of pipe joint polishing technology, and in particular to polishing fixtures for gas pipe joints. Background Technology

[0002] Gas pipeline joint polishing refers to the surface treatment process of gas pipeline connection parts. The purpose is to remove burrs, oxide layers and unevenness, improve surface smoothness, and ensure sealing and connection strength. It is usually achieved by mechanical or chemical methods and is an important process in pipeline installation and maintenance. Currently, polishing fixtures are required to clamp and fix the gas pipeline joints during the polishing process.

[0003] Existing gas pipeline joint polishing fixtures typically include a fixed base, a clamp for holding the joint, and a polishing wheel driven by a drive mechanism. The polishing wheel is positioned on one side of the joint to polish that side of the surface.

[0004] When polishing the entire circumferential surface of a pipe joint, after polishing one side of the joint, it must be removed from the fixture, its orientation adjusted, and then re-clamped before the unpolished other side can be processed. This repeated disassembly and reassembly not only increases the labor intensity and working time of the workers, resulting in low polishing efficiency, but also makes it difficult to obtain a uniform polishing quality on the entire joint surface due to the slight positional deviation that may occur with each clamping, which is not conducive to its use. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe 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 construed as limiting the scope of the invention.

[0006] In view of the problems existing in the polishing tooling of gas pipeline joints, the present invention is proposed.

[0007] Therefore, the problem that this invention aims to solve is that the existing gas pipe joint polishing fixture does not have an automatic orientation adjustment function. After polishing one side of the pipe joint, it is necessary to disassemble the pipe joint and re-clamp it, resulting in low polishing efficiency.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a gas pipeline connector polishing fixture, which includes a base and an automatic flipping assembly.

The fan is used to deliver external air into the collection shell and deliver the filtered air to the exhaust pipe. The exhaust pipe can deliver airflow to the front side of the control shell to push the dust generated during the polishing process into the interior of the collection shell.

[0013] As a preferred embodiment of the gas pipeline joint polishing fixture of the present invention, the rear side of the collection shell is provided with a movable opening for use with the filter element, and both sides of the top front side of the sealing plate are fixedly connected to the collection shell by bolts. The movable opening facilitates the installation and fixing of the filter element, the sealing plate can seal the movable opening, and the bolt fixing facilitates the worker to clean or replace the filter element.

[0014] As a preferred embodiment of the gas pipeline joint polishing fixture of the present invention, a slide rail is fixedly connected to the bottom of the inner cavity of the control housing, a slide sleeve is slidably connected to the surface of the slide rail, and the top of the slide sleeve is fixedly connected to the threaded sleeve.

The installation sleeve can limit the limiting tube, prevent it from shaking during movement, and improve the stability of the friction plate during movement.

[0018] The beneficial effects of this invention are as follows: The automatic flipping component design utilizes a servo motor to control the screw rotation, causing the threaded sleeve to move the extrusion roller, thereby adjusting the clamping position of the pipe joint. When the drive motor controls the rotating shaft to rotate, the pipe joint can automatically flip, eliminating the need for disassembly and re-clamping. This reduces the labor intensity of workers, improves polishing efficiency, and ensures the uniformity of the polishing quality of the joint surface, avoiding positional deviations caused by repeated clamping. The locking mechanism design uses an electric cylinder to control the extrusion block to press down on the slope block, causing the connecting arm to push the friction plate into close contact with the rotating shaft, achieving stable locking of the joint and preventing accidental movement during polishing. This improves the precision and safety of the polishing operation, ensures uniform polishing of all surfaces of the joint, and further enhances polishing quality and operational reliability.

[0030] A dustproof mechanism 10 is provided on the rear side of the base 1. The dustproof mechanism 10 includes a collection shell 101. The front side of the collection shell 101 extends to the front side of the base 1. A filter element 102 is provided in the inner cavity of the collection shell 101. The rear side of the filter element 102 extends through the collection shell 101 and is fixedly connected to a sealing plate.

[0032] The working principle of this invention is as follows: When polishing a gas pipeline joint is required, the joint is first placed on the surface of the extrusion roller 54. The servo motor 51 is started, and the servo motor 51 drives the screw 52 to rotate, causing the threaded sleeve 53 to push the extrusion roller 54 closer to the rotating shaft 4, clamping and fixing the joint. Then, the drive motor 3 is started, and the drive motor 3 drives the rotating shaft 4 to rotate, causing the joint to rotate accordingly. The polishing equipment polishes the surface of the joint. After one side of the joint is polished, the drive motor 3 continues to work, and the rotating shaft 4 drives the joint to automatically flip, so that the unpolished surface faces the polishing equipment. No disassembly or re-clamping is required, achieving continuous polishing and improving work efficiency. During the polishing process... If it is necessary to fix the joint position, the electric cylinder 62 can be activated. The electric cylinder 62 pushes the pressing block 63 to press down the slope block 64. The slope block 64 overcomes the elastic force of the spring 65 and moves to the left, driving the connecting arm 66 to push the friction plate 67 to make close contact with the rotating shaft 4, generating friction to prevent the rotating shaft 4 from rotating, thereby locking the joint and ensuring polishing accuracy. The metal dust generated during polishing is sucked into the collection shell 101 by the exhaust fan 104. After the air is filtered by the filter element 102, the dust is trapped in the collection shell 101. The clean air is discharged through the exhaust pipe 105. The generated airflow pushes the dust to the inlet of the collection shell 101, making it easy for it to be sucked into its interior for filtration, keeping the working environment clean.
