Description

Technical Field

[0001] The utility model relates to the technical field of industrial processing, in particular to an adjustable top plate for machining. Background Technique

[0002] The turning of the outer circle of pipes is an important metal processing technology. It can not only change the shape and size of pipes, improve the surface quality and strength, but also achieve precise control, improve the processing efficiency and quality. Therefore, the wide application of the outer circle turning technology in industrial production is of great significance for improving product quality and competitiveness.

[0003] However, the processing of pipe materials is more difficult. Before processing, it is necessary to fully understand the properties and characteristics of the pipe materials, and select a suitable processing technology according to the situation. Generally, lathe processing is adopted. The pipe materials are clamped by a fixture or a slider and then processed. However, the existing fixture has a simple structure and can only adapt to a single pipe material. It cannot be reasonably adjusted according to the holes of the pipe material. After one pipe is processed, a new fixture needs to be replaced to continue processing, which is time-consuming and laborious. If an inappropriate fixture is used to force the processing, it will cause damage to the pipe material, reduce the production efficiency. At the same time, the unstable fixture will cause the clamped pipe material to fall off, which will pose a safety hazard to the operator. Therefore, we propose an adjustable top plate to solve the above problems. Content of the Utility Model

[0038] When the device is used, the operator grasps the top plate body 1 and puts it into the interior of the pipe to be processed, and rotates the handle 503 at one end of the two-way screw rod 502 through the positioning mechanism 5, so that the fixed plate 501 drives the extension plate 401 to move, and the position of the extension plate 401 coincides with the outer wall of the pipe, and the connecting bolt 403 at one end of the extension plate 401 is rotated to fix the position of the extension plate 401, so that the outer surface of the fixing block 404 at the other end of the extension plate 401 is against the outer surface of the outer wall of the pipe. The function of the clamping piece 402 is to extend the fixing range of the connecting bolt 403, so that the connecting bolt 403 does not need to be very large to firmly fix the extension plate 401, and rotate the multiple groups of radial adjustment bolts 2 inside the top plate body 1 so that the top thereof is against the inner wall of the pipe, and tighten the nut at the bottom of the radial adjustment bolt 2 to complete the fixing of the top plate body 1, and put the fixed pipe into the lathe, use the live center to support the center hole 6, and fix the top plate body 1 at the other end, and the preparation work before pipe processing is completed.

[0044] The positioning mechanism 5 includes a fixing plate 501 and a bidirectional screw rod 502;

[0045] The positioning mechanism can effectively prevent the entire top plate body 1 from being offset, ensuring that the top plate body 1 is located in the middle of the pipe without affecting subsequent processing.

[0046] The fixing plate 501 is fixedly mounted on the end of the extension plate 401 facing the center point, and the bidirectional screw rod 502 is threadedly connected inside the two sets of fixing plates 501 .
