Protective cover fixing device of machine tool telescopic protective cover test machine

Abstract

The invention discloses a protective cover fixing device of a machine tool telescopic protective cover test machine. The protective cover fixing device is composed of a fixing plate fixedly connected with a slide stage of the test machine, a left fixing plate fixedly connected with a left adjustable linear guide rail, a right fixing plate fixedly connected with a right adjustable linear guide rail, and a plurality of n-shaped quick chucks; a plurality of screw thread holes I are formed in the fixing plate, the left fixing plate and the right fixing plate; one end of each n-shaped quick chuck is provided with a screw hole II; the fixing plate, the left fixing plate and the right fixing plate are respectively provided with a plurality of n-shaped quick chucks; and the fixing plate, the left fixing plate and the right fixing plate are respectively in threaded connection with the n-shaped quick chucks through the screw thread holes I and the screw holes II on the n-shaped quick chucks. With the above technical scheme adopted, the protective cover fixing device of the machine tool telescopic protective cover test machine has the advantages of simple structure, low cost, fast fixation of protective covers of different specifications, and high fixation efficiency.

Description

technical field [0001] The invention belongs to testing equipment specially for testing telescopic protective covers of machine tools of various specifications, and in particular relates to a protective cover fixing device of a machine tool telescopic protective cover testing machine. Background technique [0002] When the machine tool is processing various workpieces, the telescopic protective cover used on the machine tool will expand and contract with the movement of the machine tool. During the expansion and contraction process, the telescopic protective cover of the machine tool will generate various noises due to friction. In the industry, the telescopic protective cover of the machine tool The noise level, tensile strength and expansion and contraction speed of the cover are important indicators of its quality. Therefore, when the machine tool telescopic cover is delivered for use, its various indicators will be tested. At present, there is no special testing equipmen...

AI Technical Summary

Problems solved by technology

At present, there is no special testing equipment for the test of the telescopic protective cover of the machine tool. The main method is to put it on the machine tool, test it during use, and then feed back the test results to the manufacturer. This kind of on-site test is carried out on the machine tool. There will be many disadvantages. First, the manufacturer cannot grasp the first-hand information on site, and the test results cannot be known during the production process. When the quality is not up to standard, it cannot be corrected in time, and it is impossible to ensure that qualified products leave the factory, which delays time and affects delivery; Second, because various machine tool telescopic shields have different sizes and specifications, on-site testing on machine tools cannot test machine tool telescopic shields of different specifications, and cannot guarantee the quality of products of different specifications; third, on-site testing on machine tools Test, because the performance of the machine tool cannot be known, the test result of the telescopic protective cover is unstable, and the test effect is not good
