Mechanical pressure slide block and bulb lead screw connecting device

Abstract

The invention discloses a mechanical pressure slide block and bulb lead screw connecting device. A first reference plane is arranged on a slide block at an upper port part of a blind hole; a second reference plane is arranged on the outer circular edge of a flange; and the thickness of a gasket is obtained by subtracting the thickness of the edge port part of the flange by the distance from the first reference plane to the second reference plane. The thickness of the gasket can be once determined accurately, so that efficiency is high, inconvenience and troubles caused by repeated trial installation of the gasket are prevented, and meanwhile, the phenomenon of abnormal wear of parts caused by inaccurate installation of the gasket and abnormal work of the parts is prevented.

Description

technical field [0001] The invention relates to a mechanical press, in particular to a connecting device between a slide block and a ball screw rod of the mechanical press, and belongs to the technical field of the mechanical press. Background technique [0002] At present, the existing connecting device between the slider and the ball screw of a mechanical press mainly includes a slider. The middle part of the slider has a blind hole with an upward opening, and the bottom of the blind hole is provided with a collapsed safety device. A ball bowl seat is arranged in the blind hole above the fuse, the ball joint part of the ball screw rod is set in the spherical pit of the ball bowl seat, and the ball cover plate is sleeved on the ball screw rod through the middle hole. The spigot part of the head cover is installed in the upper part of the blind hole. A gasket is provided between the flange part of the ball head cover and the upper plane of the slider, and the bolt passes thr...

[0002] At present, the existing connecting device between the slider and the ball screw of a mechanical press mainly includes a slider. The middle part of the slider has a blind hole with an upward opening, and the bottom of the blind hole is provided with a collapsed safety device. A ball bowl seat is arranged in the blind hole above the fuse, the ball joint part of the ball screw rod is set in the spherical pit of the ball bowl seat, and the ball cover plate is sleeved on the ball screw rod through the middle hole. The spigot part of the head cover is installed in the upper part of the blind hole. A gasket is provided between the flange part of the ball head cover and the upper plane of the slider, and the bolt passes through the hole on the flange plane of the ball head cover. The through hole fixes the ball head cover and the slider together. In the above structure, the gasket plays the role of adjusting the gap between the ball joint of the ball head screw, the ball bowl seat and the ball head cover. In the structure, the gap between the ball joint, the ball bowl seat and the ball head cover needs to repeatedly adjust the thickness of the gasket to get the best gap. The adjustment process is not only cumbersome, but the efficiency is low, especially there are inaccurate Defects, causing abnormal wear between parts, reducing the service life of parts, and causing the entire mechanism to work abnormally
