[0003] At present, the performance parameter detection of the electric spindle is to directly connect the electric spindle to the dynamometer for measurement, but the maximum speed of the existing dynamometer is 30000rpm, so it is difficult to meet the measurement requirements of the high-speed electric spindle
The data acquisition of high-speed measurement can be realized by photoelectric coupling detection technology, but in order to ensure the high-speed rotation and smooth operation of the electric spindle, the elastic shaft of the electric spindle under test, the loading electric spindle and the photoelectric detection device must be strictly aligned. Therefore, the performance test of the electric spindle is required The bench has the function of high-precision adjustment of coaxiality. Although there is a test bench for "a motorized spindle performance test bench (CN201110140866.9)", this bench can only be adjusted in three dimensions. If the axis of the loading electric spindle is not parallel, it cannot be adjusted, and its adjustment accuracy is restricted by the clearance of the slideway, which makes it difficult to meet the coaxiality requirements of high-speed testing

Embodiment Construction
[0015] The present invention will be further described in detail below with reference to the drawings and embodiments.
[0016] See figure 1 , figure 2 This embodiment includes a horizontal mounting base 1. Two support assemblies 10 are fixed on both ends of the mounting base 1. The tested electro-spindle 9 and the loading electro-spindle 3 are mounted on the support assembly 10 at both ends. The fixed three-jaw chuck 2 is clamped; the photoelectric detection device 4 is fixed in the middle of the mounting base 1, and the two ends of the elastic shaft of the photoelectric detection device 4 are respectively connected with the output shafts of the tested electric spindle 9 and the loading electric spindle 3. The rotation axis of the loaded electric spindle 3, the elastic shaft and the tested electric spindle 9 are on the same axis; the tested electric spindle 9 is controlled by the frequency conversion device to control the test detection speed; the loaded electric spindle 3 is co...

The invention belongs to the technical field of performance measurement of machine tool components and in particular relates to an electric spindle performance testing bench. The electric spindle performance testing bench comprises a horizontally arranged installation base; two support assemblies are installed at two ends of the installation base; two ends of a measured electric spindle and a loading electric spindle are clamped through three-claw chucks which are fixed on the support assemblies; a photoelectric detection device is fixed in the middle of the installation base; two ends of an elastic shaft of the photoelectric detection device are respectively connected with output shafts of the measured electric spindle and the loading electric spindle and rotation axes of the loading electric spindle, the elastic shaft and the measured electric spindle are in the same axis. The electric spindle performance testing bench is simple in structure, can conveniently adjust the coaxiality of the measured electric spindle, the loading electric spindle and the elastic shaft of the photoelectric detection device and satisfies the high-speed test requirements coaxiality.
Description
Technical field [0001] The invention belongs to the technical field of performance measurement of machine tool components, in particular to an electric spindle performance test bench. Background technique [0002] With the rapid development of modern machining towards high-speed, the requirements for machine tool spindles are getting higher and higher. Electric spindles (also known as built-in spindle units) have the characteristics of compact structure, high speed and high precision, and have become an important function of high-speed processing machine tools. One of the components, because its speed is more than 100,000 revolutions per minute, it is difficult to test the performance parameters of the electric spindle such as power, torque, and speed. [0003] At present, the performance parameter test of the electric spindle is to directly connect the electric spindle with the dynamometer for measurement, but the maximum speed of the existing dynamometer is 30000rpm, so it is dif...
