Detection system of feeding precision of revolving body special-shaped curve mechanism and detection method thereof

Abstract

The invention provides a detection system of feeding precision of a revolving body special-shaped curve mechanism and a detection method thereof. The revolving body special-shaped curve mechanism comprises a revolution matrix and a peripheral positioning part; a positioning pin on the peripheral positioning part is embedded into a special-shaped curved groove on the revolution matrix and can freely make sliding movements in the groove. The detection system includes an optical autocollimator, a reflector, a rotary table and a height indicator, wherein the rotary table can record a rotation angle and the height indicator is used to measure the height of the peripheral positioning part. The revolution matrix is horizontally fixed on the rotary table; the reflector is vertically fixed on the peripheral positioning part; and the optical autocollimator is fixedly arranged and the collimation axis of the optical autocollimator is horizontally aligned to the reflector. According to the invention, the detection result is reliable; the detection method is flexible; the efficiency is high; and the method is easy to popularize.

Description

technical field [0001] The invention belongs to the field of optical-mechanical assembly and adjustment detection, and relates to a detection system and a detection method for the feed accuracy of a special-shaped curve mechanism of a revolving body. Background technique [0002] With the development of science and technology, in the field of engineering, engineers have increasingly realized that the purpose of simplifying the structure and improving performance can be achieved by using the special-shaped curve mechanism of the gyratory to replace the complicated mechanical structure. The reason why the special-shaped curve mechanism of the rotary body can replace the complicated mechanical structure is that when it rotates at the same angle, the motion feed can provide the feed amount according to the actual application needs, and it has the advantages of simple structure. [0003] The feeding principle of the special-shaped curve mechanism of the rotary body: [0004] lik...

[0008] 2. From the perspective of detection tools, the use of three-coordinate measuring machines has the following disadvantages: 1. The bulky size limits the flexibility of detection work; 2. The detection efficiency is low, especially when high-intensity detection is required. With the increase of sampling points on the space curve, the detection workload also increases, which is time-consuming and labor-intensive; 3. The detection cost is high, especially the three-coordinate measuring machine is expensive
