An automatic mechanical fixture for workpiece flipping that is convenient for quickly locating the position of the workpiece

Abstract

An automatic mechanical fixture for workpiece turnover that is convenient for quickly locating the position of the workpiece. The opposite sides of the two support plates are equipped with self-positioning clamping parts, and the surfaces of the first threaded rod and the second threaded rod are jointly threaded with internal thread sleeves. , the surface of the internal threaded sleeve is connected with a sleeve for fixed axis rotation, and the inner wall of the sleeve is slidingly socketed with the surface of the second threaded rod. The flip-type extrusion part that presses the workpiece and turns it over. Two connecting rods are hinged on the opposite sides between the connecting plate and the sleeve. The opposite ends of the two connecting rods are jointly hinged with a fixed plate. The internally threaded sleeve rotates and moves the driving part. The invention can self-position, clamp and fix the workpiece, and can automatically adapt to the effects of different workpiece clamping forces, has high processing precision, and reduces the phenomenon of unstable clamping force caused by artificial judgment of the clamping force.

Description

technical field [0001] The invention relates to an automatic mechanical fixture, in particular to an automatic mechanical fixture for workpiece flipping which is convenient for quickly positioning the position of the workpiece, and belongs to the technical field of workpiece fixtures. Background technique [0002] At present, in the production process of some workpieces, it is often necessary to turn the workpiece as a whole. Manual turning will damage the surface of the workpiece, and the labor intensity of workers is high and the production efficiency is low. Although the existing mechanical fixture can realize the turning of the workpiece, due to the turning process Due to the instability of the fixation, loosening occurs in the middle, which affects the machining accuracy. Moreover, each time the mechanical fixture clamps the workpiece, the operator often judges the clamping force manually, which cannot effectively adapt to the clamping force of different workpieces.

[0002] At present, in the production process of some workpieces, it is often necessary to flip the workpiece as a whole. Manual flipping will cause damage to the surface of the workpiece, and the labor intensity of the workers is high, and the production efficiency is low. Although the existing mechanical fixtures can realize the flipping of the workpiece, due to the flipping process Due to the instability of the fixation, the problem of loosening occurs, which affects the processing accuracy, and every time the mechanical fixture clamps the workpiece, the operator often judges the clamping force artificially, which cannot effectively adapt to the clamping force of different workpieces.
