Abstract

A kind of processing method of rotor reaming block, the coarse-fine processing through lathe process outer round surface and end face form semi-finished product one；After processed center processing, the identical semi-finished product two of two sizes are obtained by wire cutting machine cutting；It is thermally treated, be finish-machined to semi-finished product three, the semi-finished product of this method available two pieces semi-finished product two after Cutter Body Processing with Machining Center, waste of material brought by a semi-finished product two can only be processed by not only solving previous semi-finished product one, and the quality of product is improved, reduce labor intensity, production cost.

Description

A kind of processing method of rotor reaming block

Technical field

The present invention relates to a kind of processing methods of rotor reaming block.

Background technique

Rotor reaming block is installed in the front end of borehole-enlarging drilling tool, and rear end is connect by lateral pin with virtual calibrator for instrument transformer, and it is damaged to play drilling Effect, is the important composition part of rotor borehole-enlarging drilling tool, directly affects working efficiency, the rate of penetration of drilling tool, play in human body The same effect of organ, but existing processing technology not only largely waste material increase cost be more difficult to guarantee it is existing Technical requirements, and with the rapid development of the development of the national economy, in the process for pulling the national economic development for capital construction In, the processing method in machinery industry production and processing using one kind quickly, efficient, economic becomes current machinery industry suddenly wait solve Certainly the problem of.

Summary of the invention

The present invention provides one kind in view of the deficiencies of the prior art and improves material utilization rate, reduces and is produced into This, reduces labor intensity, improves a kind of processing method of rotor reaming block of product quality.

A kind of processing method of rotor reaming block, the process of the technique are as follows: 1, scale is for bar → 2, rough turn outer circle Obtain semi-finished product one so that semi-finished product one formed the not equal stub end of both ends diameter and small head end → 3, fine turning outer circle and end face → 4, small head end end face mill two centrosymmetric eccentric shaft → 5, rotor block is cut along center, form the identical semi-finished product of two sizes Two → 6, milling stub end bias → 7, microcephaly end mill side → 8, quenching → 9, brill perforation → 10, permanent tooth → 11, shot-peening.

The process of specific technique is as follows: 1, standby bar, sawing machine cutting stock → 2 are clamped outside bar using center lathe Circle corrects rear car bar outer circle and end face by outer circle, so that bar, which is formed, has the half of different-diameter stub end and small head end Finished product one → 3 clamps outer circle using numerically controlled lathe, one outer circle of smart car semi-finished product and end face → 4, clamped using machining center half at One stub end outer circle of product, outer circle correction, is gone out two centrosymmetric eccentric shaft → 5 in microcephaly's end mill, is positioned using wire cutting machine Two eccentric shafts of small head end, after correction in step 4 symmetry axis cut, obtain the identical semi-finished product two → 6 of two sizes, Clamp the small head end outer circle of semi-finished product two using machining center, correction milling stub end eccentric shaft → 7, clamped using machining center it is small Head end eccentric shaft clamps small head end outer circle to microcephaly end mill side → 8, quenching → 9, using machining center, corrects, bore major part end tooth Hole → 10 carry out knob → 11, shot-peening and removal surface and oil contaminant and oxide skin with tooth according to aperture using axis press.

Due to using above-mentioned operation, goes out two centrosymmetric eccentric shafts in one microcephaly's end mill of semi-finished product, pass through wire cutting Semi-finished product one are cut into the identical semi-finished product two of two sizes by machine, so that processing cost substantially reduces, stock utilization 2 times are promoted, the precision of product is improved, improves the quality of product.

Specific embodiment

Below in conjunction with specific embodiment, the present invention is described further.

This processing process is as follows: stock (cutting to obtain through sawing machine by bar) → rough turn outer circle (center lathe three-jaw Gripper chuck outer circle corrects turning and end face, and turn around vehicle other end and outer circle, obtains diameter not equal outer circle i.e. major part and small Head) (numerically controlled lathe scroll chuck presss from both sides major part outer circle, smart car microcephaly outer circle and end face to → fine turning outer circle, turns around to press from both sides microcephaly's outer circle, school Positive smart car major part outer circle and end face) (machining center scroll chuck presss from both sides major part outer circle to → milling microcephaly bias, and correction mills microcephaly two Centrosymmetric bias) → cutting rotor block, (wire cutting special fixture positions two eccentric shafts of microcephaly, claims in pairs after correction from center Incision obtains the identical rotor block of two sizes) → milling major part eccentric (machining center scroll chuck folder microcephaly's eccentric excircle, correction milling Major part is eccentric) → microcephaly milling side (machining center presss from both sides microcephaly's eccentric shaft top major part centre bore, milling side) → heat treatment (quenching) → brill Perforation (machining center presss from both sides microcephaly's outer circle, and major part perforation is bored in correction) → permanent tooth is (according to aperture with being pressed after tooth through axis press Tooth) → shot-peening (shot-peening and removal surface and oil contaminant and oxide skin).Processing technology of the present invention solves a previous blank only It is capable of processing a finished product, so that all the time at high cost, the problems such as waste of material is serious, large labor intensity.Using above-mentioned processing Two pieces product can be obtained after same blank processing after technique, improve material utilization rate, reduce production cost, and by adding The quality of product greatly promotes after the processing of work center.

Claims
