Problems solved by technology

[0002] All grinding machine processing equipment needs to have a grinding wheel chuck for clamping the grinding wheel. Most of the grinding wheel chucks in the prior art are installed manually, which is labor-intensive and time-consuming; the connection between the grinding wheel chuck and the grinding spindle is connected by a large cone and a nut Compression, this type of connection cannot realize free exchange between the grinding wheel chuck and the grinding spindle of the machine tool
With the development of science and technology, a type of grinding equipment such as CNC grinding machining center machine tools needs a grinding wheel chuck that can be used and exchanged in the grinding wheel library. Installed and used in the library or other grinding equipment and freely exchanged
In some milling and boring machining center machine tools, the connection between the tool magazine device and the cutting spindle adopts the sleeve-type positioning installation form, and the shaft and the hole are matched. This sleeve-type positioning installation form is used in general grinding machine tools. not applicable

Embodiment

[0016] As shown in FIG. 1 , it is a ferrule-type grinding wheel chuck which is composed of a chuck body 1 , a pressing disc 2 and a ferrule 3 ; the grinding wheel 9 is installed on the chuck.

[0017] As shown in Figure 1 and Figure 2, the chuck body 1 has a cylindrical inner hole 7, and a clamping ring groove 8 connected with the main shaft tensioning mechanism A is arranged in the cylindrical inner hole, and the inclined surface of the clamping ring groove 8 is The angle is 45 degrees, and the groove width is 15mm, forming a point contact with the three positioning steel balls of the tensioning mechanism of the grinding head spindle; The inner cone of the cone body 4 is 45 degrees, and the large end size of the inner cone is 52mm. This small-sized cone is convenient for positioning and installation with the main shaft, and is convenient for machining. The left end of the cylindrical inner hole is provided with a counterbore 14 and 6 axial screw holes 12 that are matched and ...
