Abstract

The invention provides a multi-type high-precision planetary roller lead screw pair precision detection device which comprises a grating ruler, a reading head, a slider, a linear guide rail, a nut sleeve, a punch molding device, a display screen and the like. The two-way positioning handle of the punch molding device is connected with a three-jaw chuck through a rotating shaft, and the three-jaw chuck clamps a lead screw for synchronous rotary motion. One end of a nut sleeve guide rod is fixedly connected with a connection plate, and the other end is fixedly connected with the nut sleeve. Both ends of the connection plate are fixedly connected with the slider and the reading head. The reading head horizontally slides on the grating ruler. The slider slides horizontally on the linear guide rail. The nut position information acquired by the reading head is displayed on the display screen during the straight nut movement. The device provided by the invention can test the return error, the two-way lead precision and the like of a planetary roller lead screw pair, has the advantages of high test precision and simple operation, and is suitable for the test of multiple types of planetary roller lead screw pairs. A reliable method is provided for the precision test of the planetary roller lead screw pair.

Description

technical field [0001] The invention relates to a planetary roller screw pair precision detection device, in particular to a multi-type high-precision planetary roller screw pair precision detection device, which belongs to the technical field of mechanical equipment precision detection. Background technique [0002] The planetary roller screw pair is a high-precision mechanical transmission mechanism that converts the rotational torque of the servo motor into linear thrust. Its basic principle is similar to that of the ball screw. However, since the planetary roller screw is in line contact, and the ball screw is in multi-point contact, the increase in the contact surface will greatly improve the bearing capacity and rigidity of the planetary roller screw. And the planetary roller screw has the advantages of high speed, long life and high motion precision. These characteristics of the planetary roller screw mechanism make it an ideal choice for applications such as harsh w...
