Ball grinder for presses

Abstract

A ball head grinding machine for press machines comprises a machine body, stand columns, a ball head screw, a rotary power head and a lifting mechanism. A main motor and a lifting board are arranged on the machine body, and a lifting screw arranged on the lifting board which is in driving connection with the main motor through the lifting screw can move on the stand columns. A regulating and grinding mechanism is arranged on the rotary power head, and operation position of a grinding motor is regulated through the regulating and grinding mechanism. The upper portion of the ball head screw is in driving connection with the grinding motor, while the lower portion of the same is arranged in a slider and drives the ball head screw to be ground in the slider through the grinding motor. A clamping mechanism used for fixing the slider is further arranged on a workbench of the machine body. By the ball head grinding machine, errors and shape-position tolerances accumulated in the processing of a ball head are beneficially removed, cooperative compactness between the slider and the ball head is improved, and abrasion between the same at work is reduced, and unsteadiness of the slider at work is solved, so that the slider is enabled to be stable and smooth at work. Therefore, the press machine is higher in pressing precision, longer in service life and high in practicability.

Description

Problems solved by technology

[0003] At present, mechanical presses generally have defects such as unstable slider movement, low working accuracy, large wear, and short service life of key parts.

Its instability depends on whether the surface fit between the ball head and the ball bowl in the slider is not tight, and the contact is uneven. Sometimes there may be an error of more than ten microns. The gap between the two is too large or too small to affect the The precision of stamping work of the whole press makes it difficult for the precision of stamping parts to meet the needs of customers for high-precision processing; and when the pressure on the ball head cannot be fully decomposed and exceeds the maximum bearing capacity of the press, the press is extremely It is easy to be damaged, and it is difficult to repair by replacing small parts, with high wear and short service life, which will greatly increase the cost of maintenance
