Fixture for anti-deformation machining of automobile aluminum alloy wheel

Abstract

The invention discloses a fixture for anti-deformation machining of an automobile aluminum alloy wheel. The fixture comprises a wheel body, wherein the wheel body consists of a wheel disk, a wheel rim, a hole groove and a center hole; a hollow column is arranged inside the wheel body; a position-limiting column is fixedly connected to the center position of the left side of the hollow column; theposition-limiting column penetrates through the center hole in a sliding manner; a rubber air bag is fixedly connected to the outer circumferential surface of the hollow column in a sleeving manner; bearings are fixedly embedded in the center positions of the left side and the right side of the hollow column; a driving shaft is sleeved with the two bearings; and the driving shaft penetrates through the hollow column. The fixture for the anti-deformation machining of the automobile aluminum alloy wheel has the advantages of avoiding deformation of the wheel rim during machining and always keeping the wheel rim in a regular round shape by utilizing the annular expansion force generated by inflation and expansion of the rubber air bag to uniformly support the wheel rim, avoiding shifting of the rubber air bag in an expansion state and avoiding damage to the surface of the wheel at the same time due to the fact that the rubber air bag has good skid resistance, and improving the machining efficiency due to the fact that the process of mounting and dismounting the fixture is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of processing aluminum alloy wheels, in particular to a clamp for anti-deformation processing of aluminum alloy wheels of automobiles. Background technique [0002] With the development of society, automobiles have become an indispensable means of transportation for people to travel. As an important accessory in automobiles, the quality of automobile wheels not only affects the appearance of automobiles, but also affects the safety of automobiles. Due to their light weight, aluminum alloy wheels , high strength, good brake balance performance, high precision, good thermal conductivity, low fuel consumption, etc., have been widely used in the field of automobile wheel hub manufacturing. [0003] Although the performance of aluminum alloy wheels is much better than that of steel wheels, during production and processing, it is necessary to perform grinding, drilling and other processes on the aluminum alloy whe...

Problems solved by technology

[0003] Although the performance of aluminum alloy wheels is much better than that of steel wheels, during production and processing, it is necessary to perform grinding, drilling and other processes on the aluminum alloy wheel blanks that have just been cast. The rim is deformed, and each deformation needs to be corrected manually before the next step of processing can be carried out, resulting in slow production efficiency
