Abstract
The utility model discloses a kind of positive reverse boring cutters of bias, the middle part of boring cutter cutter hub is equipped with knife rest with installation end coaxial arrangement and circumferential direction, the large diameter hole of one end of workpieces processing is used on knife rest equipped with blade, the tail end of boring cutter cutter hub with respect to middle part eccentric setting and is equipped with diamond segment in tail end, diamond segment is used for the small diameter bore of another end of workpieces processing, distance of the diamond segment blade apart from boring cutter cutter hub axis is not greater than the diameter of via in the middle part of workpiece, and the blade of knife rest and the distance of diamond segment are more than the length of via in the middle part of workpiece.Eccentric positive reverse boring cutter from the major diameter nose end of workpiece is stretched into, enters minor diameter nose end by middle part via, so as to fulfill positive and negative bore hole；Diamond segment enable through the small diameter bore of via workpieces processing in the middle part of workpiece, and ensures to enter in workpiece fabrication there are enough strokes and combine the bias of itself in cutter hub to pass through via in the middle part of workpiece, improves machining accuracy and efficiency.
Description
Technical field
The utility model is related to machining tool technical fields.
Background technology
Workpiece as shown in Figure 2 is provided with the small three-level stepped hole in the big centre in both ends, including large diameter hole a, small straight
Footpath hole b and mider hole c, the diameter in three holes are different.Interstitial hole is usually first processed, then processes left end macropore and right end respectively
Macropore when processing the macropore of left and right ends, using different boring cutters, it is necessary to carry out both sides clamping, affects the processing essence of workpiece
Degree, while processing efficiency is reduced again.
Utility model content
For more than technical problem, the utility model is intended to provide a kind of positive reverse boring cutter of bias, and the centre first processed is small
Hole is as via, using same cutter, after clamped one time, can first post-processing left and right ends macropore, avoid clamping twice and shadow
Ring machining accuracy and processing efficiency.
For this purpose, technical solution is used by the utility model：A kind of positive reverse boring cutter of bias, it is described including boring cutter cutter hub
The middle part of boring cutter cutter hub is equipped with knife rest with installation end coaxial arrangement and circumferential direction, and blade, which is housed, on the knife rest is used for workpieces processing
The large diameter hole of one end, the tail end of boring cutter cutter hub is equipped with diamond segment with respect to middle part eccentric setting and in tail end, described
Diamond segment is used for the small diameter bore of another end of workpieces processing, distance of the diamond segment blade apart from boring cutter cutter hub axis
L is not greater than the diameter D of via in the middle part of workpiece so that diamond segment can pass through via in the middle part of workpiece, the blade of the knife rest
It is more than the length of via in the middle part of workpiece with the distance of diamond segment.
As the preferred of said program, the middle part of the boring cutter cutter hub with tail end by two stage steps shaft part transition, and
The afterbody of two stage steps shaft part, which is provided with, cuts bevel phase.Increase two stage steps shaft part and combine and cut bevel phase transition, can enhance partially
The integral strength of the positive reverse boring cutter of the heart.
Further, totally two, the knife rest, circumferential direction are distributed on the middle part of boring cutter cutter hub.
The beneficial effects of the utility model：Workpiece medial small hole is borrowed as boring cutter via, by eccentric just reverse boring cutter from work
The major diameter nose end of part stretches into, and enters minor diameter nose end by middle part via, can first boring large diameter hole boring minor diameter again, also may be used
With first boring small diameter bore boring large diameter hole again, so as to fulfill positive and negative bore hole；By limiting diamond segment blade apart from boring cutter knife
The distance of body axis is not greater than the diameter of via in the middle part of workpiece so that diamond segment can pass through and hole machined work is crossed in the middle part of workpiece
The small diameter bore of part is more than the length of via in the middle part of workpiece by the distance of the blade and diamond segment that limit knife rest, it is ensured that
Enter in workpiece fabrication there are enough strokes and combine the bias of itself in cutter hub and pass through via in the middle part of workpiece.Using same
Cutter, after clamped one time, can first post-processing left and right ends macropore, avoid clamping twice and influence machining accuracy and processing effect
Rate.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the Workpiece structure schematic diagram of the utility model processing.
Specific embodiment
It further illustrates with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of positive reverse boring cutter of bias, is mainly made of boring cutter cutter hub 1, knife rest 2, diamond segment 3.
The installation end of boring cutter cutter hub 1 is fixed for the installation of itself, and middle part and the installation end of boring cutter cutter hub 1 are coaxially disposed simultaneously
Circumferential direction is equipped with knife rest 2.Preferably, totally two, knife rest 2, circumferential direction are distributed on the middle part of boring cutter cutter hub 1.
As shown in Figure 1, Figure 2, the large diameter hole a of one end of workpieces processing, boring cutter cutter hub to be used on knife rest 2 equipped with blade
1 tail end is equipped with diamond segment 3 with respect to middle part eccentric setting and in tail end, and diamond segment 3 is another for workpieces processing
The small diameter bore b of end.
Distance of 3 blade of diamond segment apart from 1 axis of boring cutter cutter hub is not greater than the straight of workpiece middle part via c so that
Diamond segment 3 can pass through via c in the middle part of workpiece, and the blade of knife rest 2 is more than via in the middle part of workpiece with the distance of diamond segment 3
The length of c.
Preferably, the middle part of boring cutter cutter hub 1 and tail end be by two stage steps shaft part transition, and in the tail of two stage steps shaft part
Portion, which is provided with, cuts bevel phase, and local diameter of axle variation is avoided to influence very much cutter hub intensity greatly.
