Abstract

A reamer repairing method relates to the field of machining and comprises the following steps: a, fixing; b, locating; c, drilling; d, inserting a tapered cotter; e, conducting trial machining and regulating. According to the method, a worn reamer is drilled in the axial direction, and the tapered cotter is inserted, so that the worn and to-be-scrapped reamer can be reused, the service life of the reamer is prolonged, the production cost is reduced, and the method is simple and practical.

Description

A kind of method of repairing reamer

Technical field

The present invention relates to field of machining, be specifically related to a kind of method of repairing reamer.

Background technology

Reamer is accurate in size multiple-cutting-edge tool, uses the reamer working (machining) efficiency high, easy and simple to handle, and the product accuracy that processes with reamer is high, quality good, and in view of the foregoing, reamer is used widely aborning at present.For a reamer, no matter process the part of what material, wearing and tearing are in use arranged, when may wear to certain limit degree, the diameter dimension of reamer can reduce, at this moment, the hole dimension that cuts with scissors out with reamer again is little, do not guarantee the size of fraising, then reamer will be scrapped processing, the method that the reamer of also wearing and tearing not being scrapped in the prior art is repaired.

Summary of the invention

Above-mentionedly scrap processing because wearing and tearing cause reamer for solving, and also it is carried out the technical problem of restorative procedure in the prior art, the invention provides a kind of simple to operately, and can greatly prolong the reamer restorative procedure in service life.

A kind of method of repairing reamer comprises the steps:

A. fixing: that the reamer of needs reparation is clipped on the lathe chuck;

B. locate: the head end in the reamer working end is determined the center;

C. boring: the center of locating in the step b is as the center of circle, axially bore along reamer and repair the hole, the diameter of repairing the hole be the reamer diameter 1/4 ~ 1/2 between, the degree of depth in hole is that reamer working portion length adds 3 ~ 30mm again;

D. insert taper bolt: select the taper bolt identical with the diameter of step c mesopore, in the reparation hole that processes among the partial insertion step c;

E. examination processing and adjustment: with the reamer processing examination fraising of the partial insertion taper bolt in the steps d, reach the standard of former reamer processing such as the diameter that tries fraising, then reamer repairs; As the value of trying to ream is also less than normal, then knock in taper bolt a bit with tup after reprocessing examination fraising and measuring, repeatedly knock in taper bolt, until meet the size in the hole that the reamer that do not wear and tear processes.

The present invention can reuse the reamer that need scrap after the wearing and tearing by the reamer of wearing and tearing being holed vertically and inserting the method for taper bolt, has prolonged the service life of reamer, has saved production cost, and method is simple, practical.

Description of drawings:

Description of drawings of the present invention is as follows:

Fig. 1 repairs the reamer schematic diagram;

Fig. 2 is at reamer end face hole structure schematic diagram;

Fig. 3 reamer structural representation;

1. diameters, 2. reamers 3. are repaired the degree of depth 5. working portion length 6. taper bolts in 4. holes, hole among the figure.

The specific embodiment:

Invention is further described as follows below in conjunction with accompanying drawing:

A kind of method of repairing reamer comprises the steps:

A. fixing: that the reamer 2 of needs reparation is clipped on the lathe chuck;

B. locate: the head end in reamer 2 working ends is determined the center;

C. boring: the center of locating in the step b is as the center of circle, axially bore along reamer 2 and repair holes 3, the diameter of repairing hole 3 be reamer diameter 1 1/4 ~ 1/2 between, the degree of depth in hole 4 adds 3 ~ 30mm again for reamer working portion length 5;

D. insert taper bolt: select the taper bolt 6 identical with the diameter of step c mesopore, in the reparation hole 3 that processes among the partial insertion step c;

E. examination processing and adjustment: with the reamer 2 processing examination fraisings of the partial insertion taper bolt in the steps d, reach the standard of former reamer processing such as the diameter that tries fraising, then reamer 2 has repaired; As the value of trying to ream is also less than normal, then with tup taper bolt 6 is knocked in a bit rear reprocessing examination and reams and measure, and repeatedly knocks in taper bolt 6, until meet the size of the reamer institute machining hole that do not wear and tear.

Because reamer is meticulousr cutter, then insert again the method for taper bolt behind the above-mentioned machining hole and can effectively repair reamer, its life-span is prolonged.

Protection scope of the present invention is not limited only to the disclosed technical scheme of specific embodiment part, thereby the method that taper bolt reaches the reparation reamer is inserted in all utilizations behind machining hole on the reamer, all fall into protection scope of the present invention.

Claims

1. a method of repairing reamer comprises the steps:

A. fixing: the reamer (2) that needs are repaired is clipped on the lathe chuck;

B. locate: the head end in reamer (2) working end is determined the center;

C. boring: the center of locating in the step b is as the center of circle, axially bore along reamer (2) and repair hole (3), the diameter of repairing hole (3) be reamer diameter (1) 1/4 ~ 1/2 between, the degree of depth in hole (4) adds 3 ~ 30mm again for reamer working portion length (5);

D. insert taper bolt: select the taper bolt (6) identical with the diameter of step c mesopore, in the reparation hole (3) that processes among the partial insertion step c;

E. examination processing and adjustment: with reamer (2) the processing examination fraising of the partial insertion taper bolt in the steps d, reach the standard of former reamer processing such as the diameter that tries fraising, then reamer (2) repairs; As the value of trying to ream is also less than normal, then with tup taper bolt (6) is knocked in a bit rear reprocessing examination and reams and measure, and repeatedly knocks in taper bolt (6), until meet the size of the reamer institute machining hole that do not wear and tear.
