Problems solved by technology

However, there is currently no reliability test device for the elastic chuck of CNC machine tools in China, and it is impossible to carry out the laboratory reliability bench test of the elastic chuck. The failure data, operation data and maintenance data can only be obtained through on-site reliability tracking tests, and then Carry out corresponding reliability analysis
However, the method of obtaining elastic chuck failure data, operation data and maintenance data by on-site reliability tracking test has a long test period, uncontrollable test, and irreproducible test results, which consume a lot of manpower, material resources and financial resources. , so the practicability of the on-site reliability tracking test method is not strong

Abstract

The invention discloses a reliability test device for an elastic chuck of a numerical control machine tool, and the device comprises a bedplate, a connecting mechanism is fixedly connected to the middle part of the upper end of the bedplate, a supporting frame is fixedly connected to the left part of the upper end of the bedplate, and a clamping hydraulic cylinder is fixedly connected to the upperend of the supporting frame. A clamping mechanism is fixedly connected to the output end of the clamping hydraulic cylinder, a detector mounting mechanism is fixedly connected to the upper portion ofthe right end of the connecting mechanism, a displacement sensor and a temperature sensor are fixedly connected to the detector mounting mechanism in a penetrating mode, and a sliding supporting mechanism is arranged on the right portion of the upper end of the table plate. A loading mechanism is arranged on the upper portion of the sliding supporting mechanism, and a console is fixedly connectedto the middle of the front end of the supporting surrounding shell. According to the reliability test device for an elastic chuck of the numerical control machine tool, the reliability test of the elastic chuck body has reproducible conditions, so that the test can be repeated, the test period is short, the test effect is better, and data obtained by the test is more valuable.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a reliability test device for elastic chucks of numerical control machine tools. Background technique [0002] CNC machine tool is an automatic machine tool equipped with a program control system, which can make the machine tool move and process parts according to the programmed program. CNC machine tools integrate machinery, automation, computer, microelectronics and other technologies to solve the processing problems of complex, precise and small batch parts. It is a flexible and efficient automatic machine tool. The elastic chuck is a key functional part of the CNC machine tool. The reliability level of the elastic chuck directly affects the reliability level of the whole machine. However, there is currently no reliability test device for the elastic chuck of CNC machine tools in China, and it is impossible to carry out the laboratory reliability benc...
