Mechanical claw for clamping workpiece

Abstract

The invention discloses a mechanical claw for clamping a workpiece, and belongs to the field of photoelectric sensor detection equipment. The mechanical claw comprises a claw base, the lower end of the claw base is movably connected with a plurality of gripping jaws, each gripping jaw comprises a clamping jaw, the upper end of each clamping jaw is connected with a connecting block, and the clamping jaws are sleeved with reset springs; and the ends, close to the center of the claw base, of the connecting blocks are provided with slopes. When the mechanical claw is used and the placing position of a workpiece has an error, the phenomenon that a plurality of clamping jaws make contact with the workpiece in sequence occurs in the closing process of the clamping jaws, the clamping jaw closest to the workpiece makes contact with the workpiece firstly, and due to the fact that the clamping jaws are powered by the reset springs, so that when the clamping jaw closest to the workpiece makes contact with the workpiece, the clamping jaw stops moving, and so on until all the clamping jaws make contact with the workpiece, and in this way, the clamping mechanism can normally clamp and place the workpiece with errors.

Description

technical field [0001] The invention relates to the field of photoelectric sensor detection equipment, in particular to a mechanical claw for clamping workpieces. Background technique [0002] At present, the detection of high-precision photoelectric sensors mainly relies on imported equipment. During the detection, the photoelectric sensor needs to be clamped to the designated position first, and then detected by the equipment. High, for example, only when the photoelectric sensor is directly below the mechanical claw can the mechanical claw be opened to clamp the photoelectric sensor, it is difficult to clamp the photoelectric sensor with errors. Therefore, the present invention provides a mechanical gripper for clamping workpieces to solve the above-mentioned problems. Contents of the invention [0003] The object of the present invention is to provide a mechanical gripper for clamping workpieces, so as to solve the problems raised in the above-mentioned background tec...
