Abstract

The invention discloses a grease injection device and method of a ball screw. The grease injection device is characterized by comprising a base and at least one grease injection part, wherein a firstpositioning support and a second positioning support are arranged on the base; a support top tip for mounting a to-be-lubricated ball screw assembly is arranged between the first positioning support and the second positioning support; a sliding block mechanism for sliding the first positioning support and the second positioning support are also mounted on the base; the grease injection part comprises a grease injection support assembly which is mounted on the base in a sliding manner; a grease injection head is arranged on the grease injection support assembly; and grease can be injected intothe grease injection support assembly which is mounted on the support top tip through the grease injection head. The invention also discloses a grease injection method. An easy original manual greaseaddition way is optimized into a grease injection way adopting the grease injection device, so that the instability of injection of the grease caused by human factors is reduced, and the grease injection quality and efficiency are improved.

Description

technical field [0001] The invention relates to the field of ball screw manufacturing, in particular to a ball screw grease injection device and a method thereof. Background technique [0002] Due to the complex structure of the ball screw, the gap between the threaded raceway of the screw and the screw nut is very small, and it is relatively difficult to inject grease into the raceway, and the symmetry of the grease injection in the ball screw and the nut raceway requires Take control. The single-point grease injection method greatly affects the efficiency of grease injection, and cannot guarantee the uniformity of the injection amount. In the use of new energy vehicles, especially high-end vehicles, ball screw is widely used. The uniformity of the grease injection on the ball screw raceway directly affects the accuracy and durability of the ball screw. [0003] The method of grease injection in small batch production is to grease the raceway of the screw rod by manually...
