Numerical control machine tool chuck reliability test device

Abstract

The invention discloses a hydraulic chuck reliability test device, which comprises a chuck working condition simulation system, a dynamic loading module, an oil mist spraying module, a loading unit module, a data measurement assembly and a hydraulic station; wherein the components are electrically connected with the equipment control module; the hydraulic station and the equipment control module are arranged beside the horizontal iron; the chuck working condition simulation system is arranged on the horizon iron; the chuck working condition simulation system is provided with a hydraulic chuck, and the hydraulic chuck is provided with a simulation loading workpiece; the dynamic loading module can respectively apply torque loading, axial loading and radial loading to the analog loading workpiece; an oil atomizing nozzle is arranged in the oil mist spraying module and sprays the hydraulic chuck to simulate the oil stain working condition; and the data measurement assembly is arranged in the simulation chuck working condition system, the dynamic loading module and the loading unit module. The technical scheme is suitable for simulated working condition loading of cutting force loads of chucks of different types and different models, and can be adjusted according to test requirements.

Description

technical field [0001] The invention belongs to a testing device in the technical field of mechanical equipment testing, and more precisely, the invention relates to a hydraulic chuck reliability testing device. Background technique [0002] Modern manufacturing technology is developing towards high efficiency, high precision and flexible manufacturing, which puts forward high speed, high precision and flexible requirements for CNC machine tools and their fixtures. In CNC lathes, the hydraulic chuck is the most commonly used workpiece fixture. It is the connection interface between the machine tool electric spindle and the workpiece. The speed, torque and rotation accuracy of the machine tool electric spindle are transmitted to the workpiece through the power chuck. In order to meet the requirements of high-speed development of CNC machine tools, hydraulic power chucks stand out from pneumatic power chucks and electric power chucks, and become the mainstream fixtures for med...
