Embodiment Construction

[0020] Such as figure 1 Shown is the principle diagram of the machine tool spindle performance testing platform of the present invention. The machine tool spindle performance test platform of the present invention includes the following units: a spindle unit 1, a test bench 22, an operating table 33, a numerical control system 44, a hydraulic station 55, a constant temperature oil tank 66, an air source 77, a protection net 88 and a test device 99. The base of the test bench 22 is welded with square steel, and the top is welded with the integral steel plate to form the foundation of the test bench 22. Various test devices 99 are installed on the top of the test bench 22, including a spindle thermal deformation detection device and a dynamic precision detection device. The spindle unit 1 is fixed on the test bench 22 by two sets of clamping devices. The front end of the spindle unit 1 is provided with a test device 99 for testing the technical performance of the spindle.

Abstract

The invention relates to a platform for testing the performance of a main shaft of a machine tool. The platform comprises a test bed, a main shaft unit, a main clamping device, an auxiliary clamping device and a detection bar, wherein the main clamping device and the auxiliary clamping device are arranged on the test bed and used for fixing both ends of the main shaft unit; and one section of the detection bar is penetrated into an axis of the main shaft unit, and the other section of the detection bar is contacted with a dynamic precision detection device and a thermal deformation measurement device respectively; the dynamic precision detection device is fixed on a transverse guide rail capable of moving along an axial direction of the main shaft unit; and the thermal deformation measurement device is fixed on a longitudinal guide rail capable of moving along a longitudinal direction of the main shaft unit. By the platform, the technical requirements on fixing of the main shaft, installation and moving of a measurements instrument and the like of fixtures or clamps which meet an experimental requirement can be met, so that technical performance data of a plurality of points of the main shaft can be tested conveniently and comprehensively.

Description

technical field [0001] The invention relates to the field of machine tool performance testing, in particular to a platform for testing the performance of machine tool spindles. Background technique [0002] Spindle components are the main functional components of CNC machine tools and one of the key factors to realize "high speed, high precision and high efficiency" of machine tools. With the continuous development of technology, the spindle unit used by high-end CNC machine tools has been separated from the machine tool structure, and is produced by machine tool factories or professional spindle manufacturers according to standardization and serialization. [0003] Generally speaking, the parameters for evaluating the technical performance of spindle components include the following aspects: [0004] Basic performance, including operation, sealing, temperature rise and noise; [0005] Advanced performance, including stiffness, thermal denaturation, dynamic accuracy, broac...
