Problems solved by technology

Therefore, when the helix angle of the threaded groove G exceeds a certain level (for example, more than 20 degrees), the strut 12 will interfere with the nut 2 and vibrate, resulting in a decrease in grinding accuracy, and even grinding may not be possible.
Even if the support rod 12 is replaced with a smaller diameter, the rigidity of the support rod 12 will be insufficient, and the grinding precision drop caused by vibration will be more serious, making the grinding work difficult

Abstract

The invention relates to a nut machining method which includes the following steps that a nut is provided, an inner surface extending in one direction is arranged on the nut, a smooth portion and a thread portion are arranged on the inner surface, the smooth portion is ground through a grinding machine, and a super polishing part rotates in the direction and stretches into the nut to grind the thread portion. The nut machining method can be used for grinding the nut with the high helical angle.

Description

technical field [0001] The invention relates to a processing method for a nut. Background technique [0002] The ball screw is a device widely used in many mechanical equipment. Its purpose is to provide a precise transmission function, which can achieve linear motion in mechanical operation, and then make the loaded machine or object move in a linear direction. . Wherein, the ball screw mainly includes a screw, a nut and a plurality of balls, the balls are accommodated in the nut, and the nut is sleeved on the screw, so that the nut and the balls can move linearly relative to the screw. [0003] However, the prior art encounters difficulties in making nuts with high helix angles. In the existing technology, such as figure 1 As shown, in order to grind the threads of the nut 2, usually the grinding wheel 11 of the forming grinder is inserted into the inner side of the nut 2 to grind the thread groove G. When the helix angle of the threaded groove G of the nut 2 is larger...
