Embodiment Construction

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

[0013] See figure 1 This embodiment includes a horizontal installation platform 9 on which a lifting platform 3 and a cross platform 7 are fixed, and a V-shaped mounting frame 2 is fixed on both the lifting platform and the cross platform. Combine figure 2 , The lifting platform 3 adopts a screw method 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. The horizontal platform uses a screw to move left and right, and the vertical platform uses a wire. The lever way realizes the movement back and forth. The installation platform 9 provides a high-precision plane reference for the equipment installed on it.

[0014] It can be seen from the figure that the loading electro-spindle 1 is installed on the V-shaped mounting...

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 for machine tool components, and in particular relates 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 machining machine tools. One of the parts, its use has been developed from internal grinding to various machining directions such as drilling, milling, boring, turning, and external grinding. [0003] Electric spindles are forming a standardized and serialized product. Users have more and more stringent requirements for the performance of electric spindles. Manufacturers are urgently required to provide detailed and reliable performance parameters suc...
