Embodiment Construction

[0019] The technical scheme of the present invention will be further described below in conjunction with the specific embodiment that accompanying drawing provides, as figure 1 The shown test device includes a mounting frame 1 and a main control platform 5. The mounting frame 1 is used to fix the main shaft. A motor 2 is arranged on the mounting frame 1 to drive the rotation of the main shaft for testing. A temperature sensor is also provided on the mounting frame 1. 3 and speed sensor 4 are used to detect temperature and speed changes, wherein at least two temperature sensors 3 are provided, one is used to detect the ambient temperature, and the other is used to detect the temperature of the main shaft A (the number of spindle temperature detection is set according to the number of bearings on the main shaft , since the heating parts of the main shaft are mainly concentrated in the bearing installation position, the temperature sensor is also set accordingly according to the a...

Abstract

The invention discloses a machine tool main shaft temperature rise test device, the machine tool main shaft temperature rise test device comprises a mounting frame for fixing a main shaft, a motor for driving the main shaft to rotate on the mounting frame, a temperature sensor and a rotating speed sensor on the mounting frame, the machine tool main shaft temperature rise test device also comprises a main control platform, and the main control platform is used for directly controlling the rotating speed of the motor so as to indirectly control the rotating speed of the main shaft. The main shaft collects temperature and rotating speed signals through the temperature sensor and the rotating speed sensor at different rotating speeds, temperature and rotating speed data are displayed through the main control platform, the temperature rise condition of the main shaft is known in real time, the temperature rise condition of the main shaft can be rapidly and accurately tested and detected through the device before the main shaft is assembled, operation is easy and convenient, efficiency is high, and data detection is more accurate.

Description

technical field [0001] The invention relates to a machine tool spindle test device, in particular to a machine tool spindle temperature rise test device. Background technique [0002] With the development of high-end manufacturing industry, CNC machine tools have been widely used in various industries. As the core precision component of CNC machine tools, the spindle component directly determines the machining accuracy and reliability of CNC machine tools. The temperature rise test requirements for the spindle in Item 4.6 of GB / T 9061-2006 "General Technical Conditions for Metal Cutting Machine Tools": During the test, the spindle should run sequentially from the lowest speed, and the running time of each speed should not be less than 2 minutes. Machine tools with interchangeable gears, belt transmission and stepless transmission can be used for low, medium and high speed operation. At the highest speed, it should run for enough time (not less than 1h) to make the spindle ...
