Ball head screw rod locking mechanism of separated press machine

Abstract

The invention discloses a ball head screw rod locking mechanism of a separated press machine. Screw rod portions of the ball head screw rod are installed inside inner threaded holes of threaded sleeves and are in threaded cooperation with the insides of the inner threaded holes of the threaded sleeves, the threaded sleeves are installed inside inner taper holes of connecting rods through outer tapered surfaces, wherein the inner taper holes have the same taper degree, and the end portions of the threaded sleeves are provided with flanges; the separated surface of an integral whole is sectionedat the center plane position to form the two completely same threaded sleeves, the circumferential location of each threaded sleeve is achieved by using the method that a locating pin circumferentially locates the flanges and the connecting rods, the axial location of each threaded sleeve is achieved by using the method that the flanges are fixed between the end faces of the connecting rods through bolts and washers, the mechanism has the advantages that the locking force is large, the locking is safe and reliable, the product quality cannot be easily affected, and safety accidents cannot easily occur.

Description

technical field [0001] The invention relates to a mechanical press, in particular to a ball head screw locking mechanism of a mechanical press, and belongs to the technical field of mechanical presses. Background technique [0002] As we all know, the function of the ball head locking mechanism of the mechanical press is to lock or loosen the ball head screw. When the ball head screw needs to be adjusted, the locking mechanism is loosened. The screw rod is locked. Since the mechanical press is working, the pressure is transmitted by the ball screw. At the same time, the impact force of the ball screw is very huge. Therefore, the locking mechanism is required to be reliable. Locking to prevent the position change of the ball screw due to no locking or unreliable locking, and the resulting quality accidents of the product, especially to prevent safety accidents caused by this. At present, although the ball screw The locking mechanism of the rod is different in principle and s...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a novel press ball screw locking mechanism for the above-mentioned defects in the existing mechanical press ball screw locking mechanism, which overcomes the problems of the existing mechanical press ball screw locking mechanism. The locking force of the screw locking mechanism is too small, the locking is unreliable, and this is likely to cause unreliable product quality and even safety accidents.
