Abstract

The invention provides a self-suction positioning mechanism and a clamp. The self-suction positioning mechanism comprises a self-suction disc and a rigid positioning piece. The self-suction disc is provided with an inner cavity. The rigid positioning piece is provided with a positioning part used for abutting against a workpiece, the rigid positioning piece is connected with the self-suction disc,and a positioning part is located in the inner cavity. When the self-suction positioning mechanism is matched with the workpiece, clamping errors are not prone to occurring, positioning is accurate and reliable, and machining of the workpiece is facilitated. The clamp comprises the self-suction positioning mechanism and an air suction clamping mechanism, the workpiece is clamped firmly and reliably, and clamping errors are not likely to exist.

Description

technical field [0001] The invention relates to the field of machining equipment, in particular to a self-priming positioning mechanism and a clamp. Background technique [0002] At present, some workpieces, such as thin-walled weak rigid parts, have the advantages of light weight, high strength and high reliability, and are now more and more widely used in industrial manufacturing, especially in aviation, aerospace, automotive and other industrial fields, but due to Thin-wall weakly rigid parts are mostly large in size and weak in rigidity, and the deformation problem is more complicated and prominent during processing. It is difficult to guarantee the processing accuracy and quality of thin-wall weakly rigid parts. Quality is becoming an increasingly prominent issue. As a prerequisite for conformal machining, clamping should be paid more attention to. In engineering, the traditional clamping method based on the six-point positioning principle is difficult to meet the con...
