Embodiment Construction

[0030] The present invention is described in detail below in conjunction with accompanying drawing:

[0031] refer to figure 1 According to the present invention, the test bench for the reliability of CNC machine tool power servo tool holder under simulated real working conditions is composed of a power servo tool holder support part, a cutting force loading part, a torque loading part, and a cutting fluid spray protection and cutting fluid recovery device.

[0032] 1. Power servo tool post support part

[0033] refer to figure 1 , figure 2 , The power servo tool holder supporting part includes a power servo tool holder support base 2 , a power servo tool holder backing plate 5 and a power servo tool holder 4 .

[0034] The base 2 of the power servo knife rest is an empty box structure, which is welded by seven flat steel plates. In order to save the weight of the box, the middle part of the plate is removed, and a reinforcing plate is set in the middle. The top surface an...

Abstract

The invention belongs to the technical field of mechanical test equipment, and relates to a test bed for simulating reliability of a power servo knife rest of a numerical control machine tool under areal working condition. The test bed is mainly composed of a power servo knife rest support part, a cutting force loading part, a torque loading part, and a cutting fluid spray protection and cuttingfluid recovery device; the cutting fluid spray protection and cutting fluid recovery device is located on the upper part of the power servo knife rest support part; the cutting force loading part is located on one side of the power servo knife rest support part, and a loading rod in the cutting force loading part directly faces the power servo knife rest; and torque loading part is placed facing the power servo knife rest. The test bed is applicable to power servo knife rests of different central heights; the function of replacing the servo power knife rests without changing a cushion plat canbe realized; by implementing the cutting fluid spray protection and cutting fluid recovery device, the test bed is more similar to the real working condition; a screw guide rail is adopted to move, ahand wheel is shaken, and the XYZ three-dimensional movement can be realized; and the hand wheel and a fine adjustment nut are adopted, so that the adjusting angle is more accurate.

Description

technical field [0001] The invention belongs to the technical field of mechanical test equipment, and relates to a test bench for simulating the reliability of a power servo tool holder of a numerical control machine tool under real working conditions. Static cutting force, loading mechanism angle and three-way position adjustment, cutting torque loading, height adjustment of torque loading mechanism, cutting fluid spray and protective device, and reliability test by dynamometer, hydraulic mixed loading and spraying device Power servo tool holder reliability test bench. Background technique [0002] In recent years, with the rapid development of the equipment manufacturing industry, my country has become a big country in the production and application of CNC machine tools. At present, the domestically developed CNC machine tools have made significant progress in precision, speed, large-scale and multi-axis linkage. However, with the increase of functions, the hidden dangers...
