Thin-wall tapered-face part cylindrical grinding locating tool and grinding method

Abstract

The invention relates to a thin-wall tapered-face part cylindrical grinding locating tool and a grinding method. The thin-wall tapered-face part cylindrical grinding locating tool comprises a connection central spindle and a tightening nut; the connection central spindle comprises a central spindle and a tapered central spindle head connected with the central spindle into a whole; the taper of thetapered central spindle head is the same as that of a taper hole in a thin-wall tapered-face part; the axial length of the tapered central spindle head is greater than the depth of the taper hole ofthe to-be-machined thin-wall tapered-face part; the length-diameter ratio of the shaft end of the connection central spindle is not greater than 6.5; and the tightening nut is far from one end of thetapered central spindle head and is movably arranged at the end of the connection central spindle. With the adoption of the thin-wall tapered-face part cylindrical grinding locating tool and the grinding method, the part is not prone to deformation, the part size and high operability are guaranteed effectively.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and relates to a grinding and positioning tool and a grinding method, in particular to a grinding and positioning tool and a grinding method for an outer circle of a thin-walled conical surface part. Background technique [0002] see figure 1 , the wall thickness of a thin-walled conical part is only 1mm, the inside and outside are both cones, and the size of the outer circle is The precision requirement is high, and the positioning is difficult during cylindrical grinding. At the same time, due to the thin-walled structure, it is difficult to guarantee the size of the external circle. The prior art when this thin-walled conical part is processed see Figure 2a to Figure 2d , where the thickened black line in each figure represents the machined surface, and its specific machining process is grinding the outer circle (finishing)——boring the inner hole——the outer cone of the car——the inner c...

Problems solved by technology

Among them, during the inner taper, the outer circle and the left end face of the part are positioned, and the right end face is clamped. After the machining is completed, the outer circle size has been guaranteed by grinding. Out of tolerance, and the outer circle is seriously deformed, showing a "drum" shape, the quality of the parts cannot be guaranteed, and the pass rate is only 30%
