Telescopic guide rail protective cover reliability test bench

Abstract

The invention discloses a telescopic guide rail protection cover reliability testing stand and solves a problem that a fault of a numerical control machine tool guide rail protection cover in the prior art is difficult to detect. The testing stand comprises a state monitoring alarm mechanism, an automatic speed change control mechanism, a protection cover telescoping mechanism and an environment test system, wherein the environment test system comprises a simulation main shaft support, a second motor, a rotary body, a cutting fluid oil tank and an oil return groove, the protection cover telescoping mechanism is mounted on the ground base through a work stand, the simulation main shaft support is mounted in front of a right side of the work stand, the second motor is mounted on a top board of the simulation main shaft support, the second motor is connected with the rotary body, the cutting fluid oil tank is mounted at a right side of the simulation main shaft support, the cutting fluid oil tank is connected with a rotary body pipeline, the oil return groove is mounted at periphery of the work stand, the cutting fluid oil tank is connected with an oil return groove pipeline, the automatic speed change control mechanism is mounted at a right side of the work stand, a frequency converter is connected with the second motor and a first motor, a humidity sensor of the state monitoring alarm mechanism is mounted on the work stand, and the humidity sensor is connected with a host industrial control computer.

Description

technical field [0001] The invention relates to a test bench applied to a numerical control machine tool, more precisely, the invention relates to a reliability test bench for a telescopic guide rail protective cover. Background technique [0002] In the field of CNC machine tools, telescopic guide rail guards are widely used, which play an effective role in preventing chips and impurities from entering the guide rail. In the long-term operation of CNC machine tools, the protective cover will often have cutting fluid leakage and guard plate disconnection, which will have a certain impact on the normal operation of the CNC machine tool, and sometimes force the CNC machine tool to stop, affecting production efficiency. [0003] At present, there are only some devices in China that can test the stability of the protective cover movement, and there is no test bench for detecting the fault phenomenon of the protective cover. Contents of the invention [0004] The technical pro...
