Abstract
A special device for processing a high-precision main shaft taper hole comprises a sleeve and a press plate, wherein the main shaft (4) provided with the taper hole is arranged inside the sleeve; a C surface of the sleeve abuts against a stepped surface D surface of a shaft shoulder of the main shaft provided with the taper hole; and the sleeve presses and fixes the main shaft provided with the taper hole through the press plate (2) and a bolt (3). Precision grinding and grinding finish technologies are adopted, and a proper assembly and adjustment method is implemented, so that stable and reliable processing and positioning precision is obtained, clamping deformation is avoided, and the processing quality of the high-precision main shaft taper hole is guaranteed.
Description
Technical field
The utility model belongs to a kind of processing isolated plant, is particularly suitable for the Precision Machining of the high-precision main shaft taper hole of the products such as turntable.
Background technology
Known spindle taper hole processing method is: use lathe three-jaw folder main shaft cylindrical, process after correction, there is following shortcoming in this installation way for the high-precision main shaft cone hole machine:
1, the benchmark cylindrical axis of part is difficult to proofread and correct to adjust and reaches high-precision requirement;
2, in process, the taper hole end of part is subject to the cutting force effect, easily causes grinding head grinding wheel axis of rotation and part datum axis to depart from;
3, the installation end endoporus of part and cylindrical are subject to excessive clamping force, cause the distortion of taper hole bus and roughness of excircle to reduce.
I just begin the research of precision processing technology by place the seventies, have accumulated abundant processing experience, am on the leading domestic level at present, have obtained multinomial scientific achievement and patent.This processing isolated plant shifts locating surface by precision machined frock just, reaches the purpose that improves the spindle taper hole machining accuracy.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of high-precision main shaft cone hole machine isolated plant, improves the machining accuracy of spindle taper hole, satisfies the spindle taper hole axis to the high-axiality technical requirement of part benchmark cylindrical axis.
The technical scheme that the above technical problem that solves the utility model adopts is: comprise sleeve and pressing plate, be provided with band taper hole main shaft in sleeve, the C face of sleeve leans the shaft shoulder step surface D face with the taper hole main shaft, and sleeve is by pressing plate and screw in compression fixed band taper hole main shaft.
The utility model has the advantages that:
1, setting accuracy on work is high: the processing locating surface of part is transferred to the shaft shoulder step surface of close spindle taper hole side by cylindrical, the high-axiality requirement of grinding head grinding wheel axis of rotation and benchmark cylindrical axis in the time of can guaranteeing the clamping location by adjusting centering, the hyperbolic error of having avoided axis runout to cause;
2, clamping deformation is little: the former radial clamping power that acts on part outer is transformed into the axial clamping force that acts on shaft shoulder step surface, and the distortion of taper hole bus and the roughness of excircle having avoided causing greatly due to the scroll chuck clamping force reduce;
3, simple in structure, easy to use: this processing isolated plant only comprises two of sleeve, pressing plates, and during use, by the method centering of global displacement, clamping is easy to adjust.

The specific embodiment
Embodiment, as Fig. 1---shown in Figure 5, comprise sleeve 1 and pressing plate 2, be provided with band taper hole main shaft 4 in sleeve 1, the C face of sleeve 1 leans the shaft shoulder step surface D face with taper hole main shaft 4, and sleeve 1 is fixed band taper hole main shaft 4 by pressing plate 2 and screw 3.
Preparation method:
1, the processing isolated plant forms: as shown in Figure 1, high-precision main shaft cone hole machine isolated plant of the present utility model comprises sleeve 1, pressing plate 2;
2, part processing before the assembling: use cylindrical grinder to finish grind part to be processed in manufacturing procedure---with benchmark cylindrical A, the taper hole end cylindrical E of taper hole main shaft 4 and by mill shaft shoulder step surface D face.Use B, the C two sides of surface grinding machine plain grinding sleeve 1 and grind the B face, then inhaling sleeve B face with internal grinder magnetic suction disc 5, by grinding set cylinder C face;
3, assembling and clamping: as Fig. 1---shown in Figure 5, band taper hole main shaft 4 sleeve 1 of packing into, the sleeve C face leans the shaft shoulder step surface D face with the taper hole main shaft, compresses with pressing plate 2 and screw 3, will process isolated plant and part is combined into assembly;
4, adjust: the taper hole end cylindrical E radial beat eccentricity of correction tape taper hole main shaft 4, by the method centering center of assembly global displacement, the axiality of grinding head grinding wheel axis of rotation and benchmark cylindrical axis can tune to optimum;
5, processing: the correct grinding spindle taper hole is to size, and taper hole axis and benchmark cylindrical axis coaxle degree and surface roughness reach requirement.
