Abstract

The invention provides a thin-wall deep-cavity piece machining jig. The jig comprises a base, a fixed side plate and a movable side plate, wherein the fixed side plate is fixedly arranged on the base,the movable side plate is movably arranged on the base, a clamping interval used for clamping a workpiece is formed between the fixed side plate and the movable side plate, the base and / or the fixedside plate and / or the movable side plate are provided with air grooves, and the air grooves communicates with the clamping interval. On one hand, the workpiece is clamped by the fixed side plate and the movable side plate, so that the contact area between the workpiece and the fixed side plate and between the workpiece and the movable side plate is large, the pressure applied on the workpiece during the clamping process is reduced, and the workpiece is prevented from being clamped; on the other hand, the side walls of the workpiece are sucked through the air suction mode through the air grooves, so that the product is not deformed and a knife is smoothly connected; and meanwhile, the gas provided by an air pump can be used for cooling the workpiece, so that the workpiece can be effectivelyprevented from being deformed by heating.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a jig for processing thin-walled deep cavity parts. Background technique [0002] Thin-walled deep-cavity parts refer to workpieces with side walls and cavities formed in the side walls. Thin-walled deep cavity parts have been widely used in various industrial fields due to their advantages of light weight, material saving and compact structure. However, due to the poor rigidity and weak strength of thin-walled deep cavity parts, a little carelessness will cause errors, and it is difficult to guarantee the processing quality. [0003] Before manufacturing thin-walled deep-cavity parts, it is necessary to fix the workpiece with a jig, and then process the inside of the workpiece with a CNC milling machine or a machining center to obtain thin-walled deep-cavity parts with deep cavities. If a good clamping effect cannot be provided and it is difficult to fi...
