Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0013] see figure 1 , the present embodiment includes a horizontally placed installation platform 9, on which a lifting platform 3 and a cross platform 7 are fixed, and a V-shaped mounting frame 2 is fixedly connected to the lifting platform and the cross platform. combine figure 2 The lifting platform 3 uses a screw to move up and down. The cross platform 7 includes a horizontal platform and a vertical platform. The horizontal platform is located on the vertical platform and forms a cross shape with each other. Rod way to achieve forward and backward movement. The installation platform 9 provides a high-precision plane reference for the equipment installed thereon.

[0014] It can be seen from the figure that the loading electric spindle 1 is installed on the V-shaped mounting frame 2 of the lifting platform 3, and the tested electric spi...

Abstract

The invention belongs to a performance measuring device for a machine tool component, and particularly relates to a performance test bench for an electric spindle. The performance test bench comprises an installation platform, wherein an elevating platform and a cross-shaped platform are fixed on the installation platform; a loading electric spindle is arranged on a V-shaped installation frame ofthe elevating platform; a tested electric spindle is arranged on a V-shaped installation frame of the cross-shaped platform; the two ends of an elastic shaft are connected with the output ends of theloading electric spindle and the tested electric spindle; a plurality of reflecting stripes of the same shape are uniformly sprayed at symmetrical positions on the outer circumferential surfaces of the two ends of the elastic shaft with a reflecting material; an optical fiber focusing lens is arranged on a focusing lens installation frame on one side of the elastic shaft; the loading electric spindle is connected with an energy feedback device; the tested electric spindle is connected with a variable-frequency device; and the optical fiber focusing lens is connected with a measuring circuit through a photoelectric switch. The performance test bench has the characteristics of simple structure, convenience for operating, accuracy in measurement and capability of realizing high rotating speed measurement through a photoelectric detection technology.

Description

technical field [0001] The invention belongs to a performance measuring device of machine tool components, in particular to an electric spindle performance testing platform. Background technique [0002] With the rapid development of modern processing to high speed, the requirements for the spindle of the machine tool are getting higher and higher. The electric spindle (also known as the built-in spindle unit) has the characteristics of compact structure, high speed and high precision, and has become an important function of high-speed processing machine tools One of the components, its use has been developed from internal grinding to drilling, milling, boring, turning, external grinding and other processing directions. [0003] Electric spindles are becoming a standardized and serialized product. Users have increasingly strict requirements on the performance of electric spindles. It is urgent for manufacturers to provide detailed and reliable performance parameters such a...
