Embodiment Construction

[0029] A performance test platform for ETC series spindles, its overall structure and layout can be found in figure 1 . In view of the fact that the content of the domestic CNC lathe spindle performance testing is relatively single, and many performance indicators that can affect the use of the spindle have not been tested, the present invention integrates the platform base I, the tested spindle box II, and the spindle rigidity measurement module. Ⅲ. Spindle temperature rise thermal deformation measurement module Ⅳ, output torque measurement module Ⅴ, belt tension measurement module Ⅵ, noise measurement module Ⅶ, hydraulic station Ⅷ, and components of the control system Ⅸ. Among them, the platform base I is used as the carrier of the mechanical structure, and a T-shaped slot for fixing is designed on it, the spindle rigidity measurement module III, the spindle temperature rise thermal deformation measurement module IV, the output torque measurement module V, and the belt tensi...

Abstract

The invention discloses a main shaft performance testing platform, and relates to a main shaft performance detecting device of a machine tool. The structure of the main shaft performance testing platform is as follows: a main shaft rigidity measuring module, a main shaft heating thermal deformation measuring module, an output torque measuring module and a belt tension measuring module are respectively arranged on a platform base; a tested main shaft box is mounted on the platform base through a main shaft box mat. The testing platform not only can accurately test such indexes of the main shaft as precision, rigidity, force, dynamic balance and overall performance, but also can simulate the influence on all performances of the main shaft under different assembly conditions to finger out reasonable assembly relationship so as to provide a certain experimental proof to the real production and assembly of the main shaft.

Description

technical field [0001] The invention relates to a machine tool spindle performance testing platform, especially a highly intensive performance testing platform that can comprehensively detect important performance indicators such as ETC series spindle precision, stiffness, force, dynamic balance, and comprehensive performance. Background technique [0002] With the development of science and technology and the continuous improvement of manufacturing technology, the demand for CNC machine tools as the mother machine of manufacturing industry is becoming more and more intense. CNC lathe is one of the technical foundations and development directions of the equipment manufacturing industry, and the spindle is the core functional component of the CNC lathe. Its performance directly determines the relevant performance indicators of the CNC lathe and is a key component representing the technical level of the CNC machine tool. Many domestic manufacturers have experience in R&D and p...
