Problems solved by technology

Since the machine tool is a structure composed of rigid parts, more than 90% of its total damping value comes from the joint surface. At present, the number and arrangement of the joint surface bolts basically rely on experience, and there are few scientific test analysis
In addition, the processing methods of the joint surface of the machine tool include grinding and milling, but due to the lack of necessary experimental analysis, it is difficult to judge the optimal contact state of the specific joint surface. Therefore, it is necessary to conduct scientific research on the joint surface. Technical problems urgently needed to be solved by those skilled in the art

Abstract

The invention discloses a test device for testing the contact characteristic of the fixed junction surface of a machine tool. The test device comprises a test table body and a pressure sensing film, wherein the test table body is provided with a T-shaped groove table board, the T-shaped groove table board is provided with a loading support, a plurality of threaded through holes are formed in the top end of the loading support at equal intervals, loading bolts are placed in the threaded through holes, the lower end of each loading bolt is connected with a steel wire rope through a lifting bolt, the lower end of each steel wire rope is connected with a tension sensor through a lifting bolt, and the lower end of each tension sensor is connected with a pre-tightening bolt. By means of the test device, the number of contact points, the machining mode, the number of bolts and the distribution of the bolts of the junction surface can be researched, and the test device provides a basis for improving the dynamic characteristic and accuracy of the machine tool.

Description

technical field [0001] The invention relates to the field of a testing device, in particular to a testing device for testing the contact characteristics of a fixed joint surface of a machine tool applied to a machine tool. Background technique [0002] The fixed joint surface of the machine tool has a very obvious impact on the dynamic characteristics of the machine tool. According to statistics, more than 60% of the vibration problems on the machine tool come from the joint surface. Since the machine tool is a structure composed of rigid parts, more than 90% of its total damping value comes from the joint surface. At present, the number and arrangement of the joint surface bolts basically rely on experience, and there are few scientific test analysis. In addition, the processing methods of the joint surface of the machine tool include grinding and milling, but due to the lack of necessary experimental analysis, it is difficult to judge the optimal contact state of the speci...
