Abstract
The utility model discloses an eccentric threaded hole set machining tool which is capable of machining a set of eccentric threaded hole working pieces. The working pieces comprise two long eccentric holes and two short eccentric holes, wherein the distance between the two long eccentric holes is A and the distance between the two short eccentric holes is B. The eccentric threaded hole set machining tool comprises a body which is provided with a first excircle hole and a second excircle hole. The first excircle hole and the second excircle hole are arranged symmetrically along a horizontal central axle of the body and the distance between the first excircle and the second excircle is B. The first excircle hole and the second excircle hole are arranged on the vertical central axle of the body. The body is further provided with a long shaft hole, a shared hole and a short shaft hole. The long shaft hole and the shared hole are arranged symmetrically along the vertical central axle of the body and the distance in between is A. The short shaft hole and the shared hole are symmetrically arranged along the horizontal central axle of the body and the distance in between is B. The eccentric threaded hole set machining tool has the advantages that the machining and alignment of the working pieces are facilitated and form and location tolerance is easily guaranteed.
Description
Technical field
The utility model relates to the frock technical field, especially relates to a kind of in groups eccentric threaded bore processing tool.
Background technology
As shown in Figure 1, on the cylindrical of eccentric threaded bore workpiece 20 screw thread is arranged in groups, the two groups of screwed holes that eccentric throw is different that distribute on it, eccentric orfice distance to foreign round center line has the symmetry requirement.That is: this workpiece 20 comprises along 2 long eccentric orfices 21 of the vertical centre axial symmetry of workpiece 20, and the distance of these 2 long eccentric orfices 21 is A, simultaneously, workpiece 20 comprises 2 short eccentric orfices 22 along the horizontal middle spindle symmetry of workpiece 20, and the distance of these 2 short eccentric orfices 22 is B.Certainly, long eccentric orfice 21, short eccentric orfice 22 lay respectively on the horizontal middle spindle, vertical center axis of workpiece 20.The conventional processing Eccentric method of workpiece: with three-jaw shimming clamping, through again revising after the first item inspection.But these workpiece 20 cylindricals have screw thread more, can not be as the clamping face.Simultaneously, the eccentric orfice phase is tangible tolerance to foreign round, and the palpus multiple clamping, unifying datum guarantee machining accuracy.
The utility model content
The purpose of this utility model provides a kind of in groups eccentric threaded bore processing tool, and it has is convenient to carry out the in groups processing centering of eccentric threaded bore workpiece, and the form and position tolerance characteristics that are easy to guarantee.
To achieve these goals, the technical scheme that the utility model adopts is: eccentric threaded bore processing tool in groups, be used for processing in groups eccentric threaded bore workpiece, this workpiece comprises 2 long eccentric orfices along the vertical centre axial symmetry of workpiece, and the distance of these 2 long eccentric orfices is A, simultaneously, workpiece comprises 2 short eccentric orfices along the horizontal middle spindle symmetry of workpiece, and the distance of these 2 short eccentric orfices is B, this in groups the eccentric threaded bore processing tool comprise body, described body is provided with:
The first outer circular hole and the second outer circular hole, this first outer circular hole and the second outer circular hole are B along the horizontal middle spindle of body distance symmetrical and between the two, simultaneously, the first outer circular hole and the second outer circular hole are positioned on the vertical center axis of body;
Major axis hole, common hole and minor axis hole, this major axis hole and common hole are A along vertical centre axial symmetry and the distance between the two of body; This minor axis hole and common hole are B along the horizontal middle spindle of body distance symmetrical and between the two.
The utility model is compared with existing technology the advantage that has: be convenient to carry out the in groups processing centering of eccentric threaded bore workpiece, and form and position tolerance is easy to guarantee.The eccentric threaded bore workpiece adds man-hour to utilize frock of the present utility model to carry out in groups, and multiple clamping does not need centering, thereby comparatively simple, can save the clamping centering time, has improved production efficiency.Simultaneously, machining accuracy relies on frock to guarantee, reduces human factor, has avoided the fluctuation of machining accuracy, has guaranteed form and position tolerance.
