Description

Technical Field

[0001] The utility model relates to the field of aluminum shell processing, in particular to an oblique-pull type clamping structure and an arc side wall clamp. Background Art

[0002] Aluminum alloy has high strength, good plasticity, excellent electrical conductivity, thermal conductivity and resistance. Aluminum alloy can obtain good mechanical properties, physical properties and corrosion resistance after heat treatment. Aluminum alloy parts can greatly improve the strength of the shell parts.

[0003] Aluminum alloy parts are usually precision-processed by CNC machine tools. The processing requires the parts to be clamped by a fixture. When the side wall of the part is curved and the fixture is not suitable, the fixture is likely to scratch the surface of the side wall of the part.

[0004] For example, the technical solution of the comparative document CN201920512028.1 discloses a fixture for processing the aluminum alloy shell of a mobile power supply, including a fixing plate, a processing frame fixedly connected to the upper surface of the fixing plate, a connecting block fixedly connected to the inner wall of the processing frame, a circular through hole opened on the side wall of the processing frame, and an electric push rod fixedly connected to the hole wall of the circular through hole, a baffle fixedly connected to the end of the electric push rod opposite to the connecting block, a clamping block fixedly connected to the opposite side of the two baffles, and a connecting plate fixedly connected to the lower surface of the two baffles. Since the contact surface between the clamping block and the part is a non-arc surface and the contact area is small, when the clamping block clamps the part, it is easy to scratch the surface of the side wall of the part. Before clamping, it is also necessary to adjust the distance of the connecting plate to prevent the electric push rod from excessively pushing the clamping block to squeeze the part, making the process of clamping the part more cumbersome.
