Aluminum alloy machining auxiliary device for automatically fixing and supporting inner wall of pipe

Abstract

The invention relates to the technical field of aluminum alloy casting, and discloses an aluminum alloy machining auxiliary device for automatically fixing and supporting the inner wall of a pipe. Thealuminum alloy machining auxiliary device comprises a shell, and a fixed frame is fixedly connected in the shell. A gear rotates, so that an eccentric disc and a rotary disc carry out intermittent reciprocating rotation, a power source is provided for subsequent clamping and supporting operation, the eccentric disc rotates, long rods of two clamping rods are close to each other and then are drawnaway from each other, the pipe is automatically fixed, and the two hands are freed up; higher safety is achieved, and the situation that when the pipe is machined, the pipe vibrates or shits is avoided; the rotary disc rotates, two supporting blocks are drawn away from each other and then are close to each other, so that the pipe is internally supported while fixed, and the situation that in themachining process, the pipe bears the impact force of a machining tool, and the inner wall is concaved is avoided; and local deformation caused by the stress action borne by the pipe and the materialof the pipe is effectively relieved, and therefore the machining quality of the pipe is guaranteed.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy casting, in particular to an aluminum alloy processing auxiliary device that automatically fixes and supports the inner wall of a pipe. Background technique [0002] Aluminum is a metal with low strength and good plasticity. In addition to the application of some pure aluminum, in order to improve the strength or comprehensive performance, it is made into an alloy. Adding an alloying element to aluminum can change its structure and performance, making it suitable for various processing materials or casting parts. The alloying elements that are often added are copper, magnesium, zinc, and silicon. According to the different alloying elements, aluminum alloys have different strengths and properties, and are widely used in the fields of industry, construction, and transportation. [0003] Aluminum alloys are often processed into plates, bars, profiles, and pipes. When tubular aluminum alloys ...

AI Technical Summary

Problems solved by technology

[0003] Aluminum alloys are often processed into plates, bars, profiles, and pipes. When tubular aluminum alloys are used, in order to meet the needs of use, processes such as cutting and drilling are often performed on the surface, and in order to ensure the processing accuracy of the pipes and quality, it is usually fixed manually, but when the pipe is processed, it is subject to a large impact, vibration or deviation occurs, manual fixing is very time-consuming and laborious, the fixing effect is relatively poor, and it is easy to cause equipment injury situation, there is a certain threat to the personal safety of the staff, and the existing pipe clamping device has a single function and cannot support the inside of the pipe. Because there is enough support inside the pipe, it can process the pipe At this time, the pipe cannot resist the impact force of the processing tool, the pipe is sunken and the inside is out of round, and the force on the pipe is too concentrated, which is prone to deformation of the pipe, which reduces the processing quality of the pipe and is not conducive to the use of the pipe.

[0004] Aiming at the deficiencies of the prior art, the present invention provides an aluminum alloy processing auxiliary device that automatically fixes and supports the inner wall of the pipe, which has the advantages of automatically fixing the pipe, internally supporting the pipe, and better processing quality, and solves the problem of poor fixing effect And the problem of poor processing quality of the pipe, automatically fix the pipe, free hands, with higher safety, avoid the vibration or displacement of the pipe during processing, which will affect the smooth progress of the processing, and the pipe is fixed at the same time Provide internal support for the pipe to avoid the impact force of the processing tool during the processing of the pipe, and the inner wall is sunken, effectively relieve the local deformation of the pipe due to the stress and its own material, and improve the processing quality of the pipe. ensure
