Abstract

The invention relates to a loading device for sphere precise grinding. The loading device comprises a motor, a worm and a gear, wherein the worm is connected with an output shaft of the motor; the gear is engaged with the worm. The gear is connected with an upper grinding disc through a press block. A first spring is arranged between the press block and the upper grinding disc. A second spring is arranged between the worm and the press block. The press block is provided with a piezoelectric sensor for detecting the suffered pressure of the second spring. The piezoelectric sensor is connected with a controller. A pressure threshold value is preset in the controller. The motor is controlled by the controller. The invention has the advantages of high grinding precision, simple structure, accurate control in the grinding process, and low cost.

Description

technical field

[0001] The invention relates to a loading device for precision grinding of spheres. Background technique

[0002] High-precision balls are important components in roundness meters, gyroscopes, bearings and precision measurement, and are often used as the benchmark for precision measurement, and play a very important role in precision equipment and precision machining. Especially it is widely used in ball bearings and is a key part of ball bearings. The accuracy of the bearing ball (spherical deviation, ball diameter variation and surface roughness) directly affects the technical indicators such as the motion accuracy, noise and life of the ball bearing, and then affects the performance of equipment and instruments.

[0003] The loading method of the ball grinding equipment directly affects the grinding accuracy and efficiency of the ball. During the grinding process, the load is precisely controlled, which can effectively control the ball processing process...
