Machine tool spindle load simulation test equipment

2021 - spindle load simulation test device 02 - 11 xing-long guo ( Qiqihar second machine ( Group) Co. , LTD. ) Many machine tools ( Such as milling and boring machine, gantry boring and milling machining center, etc. ) After completion of the assembly of the main shaft, we need to do commissioning test, used to test the performance of the spindle system, most manufacturers are empty running test is done first, and then do the machine cutting test. If the spindle system have what problem, or want to adjust processing and performance parameters of the spindle, all need through the machine to the results of cutting test, results and design have significant deviation, may need to install the machine after removal to readjust. Described in this article the load simulation test device, the machine tool spindle before the machine assembly, drive components can be tested after the completion of main shaft system, so that it can simulate the actual machining process, the processing performance of the spindle system for all kinds of test in advance, if have what problem, can be resolved before the machine assembly. And this device in all kinds of load simulation of the test process of quantity adjustment is convenient, in the process of debugging assembly in factory workshop, very suitable. Test device has the advantages of this device as shown in the appended drawings, structure is mainly composed of the following sections. : (1) rotary joint is used to two pressure in the oil transfer to rotating parts. (2) the axial loading hydraulic cylinder: designed for main shaft axial loading force. (3) the radial load cylinder: designed for the spindle radial loading force. (4) to simulate the rotation drive: to simulate actual cutting tool and the workpiece. 5) connect the handle: used for connecting the main shaft, can use ISO40/50/60 ( 7∶24） International standards, or other handle connection type. 1 spindle load simulation test device. The handle; 2. The radial load hydraulic cylinder; 3. Servo motor; 4. Axial loading hydraulic cylinder; 5. Spinning pulley; 6. Working principle of the rotary joint working principle of the device are as follows: first of all, the device is fixed to the machine tool spindle front ends, and then through the spindle automatic broach institutions grasp the handle part of the device, then can drive the spindle rotating commissioning tests are carried out. When need to spindle applied load, through the hydraulic control unit ( Need to provide another, this article does not do detailed introduction) To control the pressure in two lines, can easily control the axial or radial hydraulic cylinder of the output force, it can be single or double loading test. In addition, this device is equipped with a simulated rolling structure, structure of the department through the servo motor drive cog belt wheel, can drive the rotating part of the whole loading device, rotation speed and positive &negative, etc can be adjust by servo motor, it can be used to simulate the actual cutting conditions of cutting tool and the workpiece. Conclusion this device in the machine tool spindle commissioning test has a good application effect, each load simulation parameters can be easily adjusted, resulting in a variety of relatively real test data, debugging of nc machine tools, especially the trial-manufacture of new products can provide a lot of help.
