Problems solved by technology

[0002] Linear guide rails have a wide range of applications, but their existing problems have not been well resolved
[0004] At the same time, the specific test device and test method have not been standardized, and there are few patents on the clamper performance detection device. Most of the patents on the clamper that can be found at present are patents for the improvement of the clamper structure, such as patent numbers: 201620285445.3 and 201720444606.3, they only improved the structure of the clamp, and did not test the performance of the clamp
Patent 201510703893.0 is about a device for detecting the reaction time and response time of the clamp for rail pairing and its measurement method. It has great limitations. It does not write the loading part of the clamp, and the function of the detection part is also very single. It only Can detect reaction time and response time

Abstract

The invention is applicable to the field of numerical control machine tools, and provides a device and a method for detecting the performance of a linear guide rail pair clamp. The detection device comprises: a workbench mechanism used for installing the clamping device; an axial loading mechanism that is provided with an axial loading detection assembly; a longitudinal loading mechanism which isprovided with a longitudinal loading detection assembly; and a performance detection mechanism which is used for detecting the clamp. The detection device can be used for detecting the performance ofthe clamp by simulating the actual machining working condition of a machine tool and collecting signals, analyzing the reliability and precision of the clamp under load and predicting the failure of the clamp to a certain extent.

Description

technical field [0001] The invention belongs to the field of numerical control machine tools, and in particular relates to a detection device and a detection method for the performance of a linear guide rail auxiliary clamp. Background technique [0002] Linear guide rails have a wide range of applications, but their existing problems have not been well resolved. The linear guide pair is in point or line contact, and the vibration damping performance is relatively poor; in the traditional machining process, the cutting force and impact load of the tool are mainly borne by the screw, which seriously affects the life and accuracy of the screw; the workpiece in the vertical direction During the upper processing, in case of unexpected situations such as power outages, the workpiece is prone to fall, causing serious safety accidents such as machine crashes and human deaths; when the linear motor is used in conjunction with the linear guide rail, since there is no braking function...
