Embodiment Construction

[0048]The invention is based on the principle of analyzing the positioning and clamping mechanism of the parts, and at the same time, combining the force applied by the tool to the parts, it can estimate the size and action direction of the part causing the deformation force, and adjust the structure of the tooling. The installation and positioning method of thin-walled parts is an important factor affecting its processing quality. The deformation of parts caused by positioning and clamping is a common phenomenon in the machinery industry. The tooling of the present invention and the positioning processing method using the tooling can effectively solve this problem. Eliminate part deformation during machining while achieving integrated machining content.

[0049] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0050] Such as figure 1 As shown, the tooling for positioning and processing thin-walled...

Abstract

The invention relates to a thin-wall part positioning and machining tool and method, and solves the problem of machining deformation caused by positioning, clamping and supporting during machining of a thin-wall part (such as a gearbox upper cover shell). The tool comprises a clamp, a four-axis rotary table and a clamp supporting frame; the clamp comprises a clamp bridge plate, at least three sets of fixing, supporting and positioning blocks, at least five sets of hydraulic auxiliary supporting cylinders, at least three sets of corner oil cylinder pressing plate assemblies, at least three sets of fixed side positioning blocks and at least three sets of pushing oil cylinder pushing block assemblies. The to-be-machined thin-wall part is positioned, clamped, supported and rotated through the tool, deformation of the thin-wall part in the machining process is eliminated, meanwhile, one-time machining of the front surface and the back surface of the thin-wall part is achieved, repeated part positioning and integrated machining procedures can be avoided, and the machining precision is improved.

Description

technical field [0001] The invention relates to a positioning processing tool and method for thin-walled parts. Background technique [0002] Thin-walled parts have poor rigidity and weak strength, and are easily deformed during processing. It is difficult to control the flatness and position of the product. The deformation of thin-walled parts has always been one of the difficulties in the industry. With the development of CNC machining equipment, the main factors of machining deformation are reflected in the positioning, clamping, and support of thin-walled parts. There are many processing methods in the industry, but there are few solutions that can eliminate machining deformation and are suitable for mass production. Contents of the invention [0003] The object of the present invention is to provide a thin-walled part positioning processing tool and method to solve the processing deformation problem caused by the positioning, clamping and supporting of thin-walled par...
