Abstract

The invention discloses a testing device for repeated positioning accuracy of a servo tool holder. The testing device comprises a magnetic base, a locating piece, a wedge block, a hollow rotary base and a rod assembly, a boss is arranged on the upper portion of the locating piece, the locating piece is fixedly connected to the magnetic base, and the wedge block is fixedly connected to the locating piece and located on the outer side of the boss. In the circumferential direction of the locating piece, an inclined face is arranged at one end of the wedge block, and a vertical face is arranged at the other end of the wedge block. The boss is sleeved with the rotary base, a gap is formed in the lower portion of the wall of the rotary base, and the gap is matched with the wedge block. The rod assembly is fixedly connected to the top face of the rotary base. The invention further discloses a testing method. According to the testing device and testing method, repeated positioning accuracy of the servo tool holder can be tested with low cost and easy operation, and meanwhile high testing accuracy can be achieved.

Description

technical field [0001] The invention relates to a test device for repeated positioning accuracy, in particular to a device for testing the repeated positioning accuracy of a machine tool servo tool holder. Background technique [0002] In terms of defense industry and manufacturing competitiveness, the machine tool industry plays a key role. Therefore, the Chinese government has raised the industry to a strategic position. One of the important revitalization goals of the country is to develop large-scale, precise, high-speed numerical control equipment and functional components. Therefore, the precision requirements for machine tools are getting higher and higher. The accuracy of the servo tool holder is an important part of the precision of the machine tool. Therefore, it is essential to test the repeat positioning accuracy of the servo tool holder, and it is becoming more and more important. The main components of the servo tool post are cutter head, end tooth plate (in...
