Description

Technical Field

[0001] This utility model relates to the field of pipe grinding technology, and in particular to a pipe grinding device. Background Technology

[0002] Pipe processing is a job that involves manufacturing pipes according to drawings. Pipe processing mainly involves processing pipes needed in industries such as industrial, chemical, civil, construction, and shipbuilding. The processing site requires a large area, and the pipe processing equipment must be able to meet the requirements of the pipe manufacturing process. Workers must be able to understand the drawings and complete the pipe manufacturing according to the process.

[0003] Currently, pipe fittings require overall grinding during processing. Existing technologies require grinding the outer and inner surfaces of pipe fittings on different grinding devices, involving multiple clamping of the pipe fittings, which is time-consuming, labor-intensive, and affects processing efficiency. Therefore, a pipe fitting grinding device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a pipe grinding device that can simultaneously grind the inner and outer surfaces of pipes, thereby improving grinding efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a pipe grinding device, comprising:

[0006] support;

[0007] The movable part is mounted on the bracket;

[0008] There are two rotating clamping parts, symmetrically arranged on the moving part. The moving part is used to drive the rotating clamping parts and the pipe to move, and the rotating clamping parts are used to drive the pipe to rotate.

[0009] A surface grinding part is provided on the moving part and located between the two rotating clamping parts. The surface grinding part and the two rotating clamping parts are at the same horizontal height and are used to grind the outer surface of the pipe.

[0010] An inner grinding section is provided on the bracket and extends through both of the rotating clamping sections and the surface grinding section, and is used to grind the inner side of the pipe fitting.

[0011] Furthermore, the moving part includes a fixed box mounted on the bracket and drive units mounted at both ends of the fixed box;

[0012] It also includes a fixing block located in the middle of the fixed box and lead screws located inside the fixed box and connected to the two drive units respectively;

[0013] It also includes two screw blocks, which are respectively set on two screws and located in a fixed box.

[0014] Furthermore, the rotating clamping part includes fixing rings respectively disposed on two wire blocks, and a rotating ring is rotatably disposed inside the fixing ring;

[0015] It also includes a driven gear mounted on the rotating ring;

[0016] It also includes a drive unit disposed on a fixed ring for driving the driven gear to rotate, wherein the output shaft of the drive unit is provided with a driving gear that meshes with the driven gear.

[0017] Furthermore, the rotary clamping part also includes a clamping telescopic rod disposed within the rotating ring for clamping the pipe fitting.

[0018] Furthermore, the surface polishing part includes a support ring disposed on the fixed block, and the inner side of the support ring is provided with a plurality of polishing telescopic rods;

[0019] It also includes a grinding disc located at the telescopic end of the grinding telescopic rod.

[0020] Furthermore, the inner grinding section includes clamping members symmetrically arranged on the bracket, and the clamping members are provided with support rods;

[0021] It also includes a telescopic component mounted on a support rod, the telescopic component being provided with an arc-shaped abrasive disc for grinding the inner side of the pipe.

[0022] The beneficial effects of this utility model are reflected in:

[0023] This invention utilizes a clamping device on one side of the inner grinding section, moving away from the support rod, to allow the pipe fitting to be sleeved on the inner grinding section. Then, a rotating clamping device on one side clamps the outer wall of the pipe fitting, causing it to rotate. The inner wall of the pipe fitting is then ground by the inner grinding section. Simultaneously, a moving part moves the rotating clamping device on one side to the surface grinding section and the rotating clamping device on the other side, where the outer wall of the pipe fitting is ground by the surface grinding section. The moving part and the rotating clamping device on the other side rotate and move the pipe fitting. Then, a clamping device on one side of the inner grinding section clamps the support rod. The clamping device on the other side of the inner grinding section moves away from the support rod, allowing the pipe fitting to be disassembled. The rotating clamping device on one side moves away from the pipe fitting to the end of the housing for further processing of another pipe fitting. This facilitates continuous grinding of the inner and outer surfaces of different pipe fittings, achieving simultaneous grinding of both the inner and outer surfaces and improving grinding efficiency.
