Abstract
The invention relates to the mechanical machining field, particularly to a machining method for improving the accuracy of the drilling position. The machining method comprises the following steps of performing the marking, rechecking and sample punch hole knocking, wherein a center line is marked according to the design requirements before drilling, an about 60-degree taper angle of sample punch is selected to enable the sample punch to be inclined outward and slide to a cross point along the cross center line, a sample punch hole is gently punched in the sample punch through a hammer after the sample punch is centralized, and the sample punch hole is enlarged through the force after the check is free of error to enable the diameter of the sample punch hole to be slightly larger than the length of the cross edge of a centering drill bit; performing drilling, wherein the appropriate centering drill bit is selected to start a drilling machine, a small drill bit is aligned to the sample punch hole of a workpiece through the little force so as to avoid scraps, the small drill bit is good in elasticity, the workpiece moves reversely until the small drill bit is not inclined when the inclination of the small drill bit due to the inclined drilling is found, the hole drilling is started, and the drilling depth is about 2 to 3 mm; selecting an appropriate drill bit to performing reaming and chamfering, performing reaming through a coarse and fine reamer and performing deburring and chamfering. According to the machining method for improving the accuracy of the drilling position, the process is simple, the position accuracy is high, and the economic benefit can be improved.
Description
Technical field
The present invention relates to field of machining, be specifically related to the processing method improving bore position precision.
Background technology
In traditional hole forming method, dimension precision between the holes is difficult to reach requirement, and the requirement of some workpiece to pitch-row is higher, and this just makes to occur in process of manufacture a lot of doing over again, and again makes, and percent defective is very high, and then processing cost is raised.
Summary of the invention
In order to solve the problem, the invention provides that a kind of operation is simple, machining accuracy is high, and the processing method of the raising bore position precision that can increase economic efficiency.
The present invention improves the processing method of bore position precision, comprises the following steps:
The first step, sample dotting punch is struck in line reinspection, center line is marked by pattern requirement before boring, and high standard will do zero-bit adjustment before line, select the sample punching of cone angle about 60 °, make sample rush flare and along cross centre line slippage to crosspoint, sample rushed righting hand hammer and stamp sample dotting punch gently, check errorless after slightly firmly add full-page proof dotting punch again, make diameter slightly larger than the chisel edge length of pilot bit;
Second step, pulls out of hole, and selects suitable pilot bit to start drilling machine, with the sample dotting punch of little drill bit alignment pieces, firmly want light, avoid chip, little drill bit good springiness, find its because of pull out of hole not just and occur crooked time, by workpiece oppositely movement, start boring until not crooked, bore dark about 2-3mm;
3rd step, reaming, selects suitable drill bit to carry out reaming and chamfering, then reams with thick, finishing reamer, deburring, chamfered edge.
Preferably, after second step completes, the center of target hole is detected to two datum level error deviation amounts with band table slide measure, target hole and desired center position offset is conversed through actual measurement, if detect aperture is apart from overproof, with the round file cutter with target hole same size, filing finishing is carried out to bottom outlet sidewall, remove trim amount with round file cutter respectively in two reference directions of this bottom outlet wall, trim part should be connected smoothly with bottom outlet circular arc, makes detect aperture apart from the margin of tolerance.
Operation of the present invention is simple, positional precision is high, and can increase economic efficiency.
Detailed description of the invention
The present invention improves the processing method of bore position precision, it is characterized in that, comprises the following steps:
The first step, sample dotting punch is struck in line reinspection, center line is marked by pattern requirement before boring, and high standard will do zero-bit adjustment before line, select the sample punching of cone angle about 60 °, make sample rush flare and along cross centre line slippage to crosspoint, sample rushed righting hand hammer and stamp sample dotting punch gently, check errorless after slightly firmly add full-page proof dotting punch again, make diameter slightly larger than the chisel edge length of pilot bit;
Second step, pulls out of hole, and selects suitable pilot bit to start drilling machine, with the sample dotting punch of little drill bit alignment pieces, firmly want light, avoid chip, little drill bit good springiness, find its because of pull out of hole not just and occur crooked time, by workpiece oppositely movement, start boring until not crooked, bore dark about 2-3mm.
After second step completes, the center of target hole is detected to two datum level error deviation amounts with band table slide measure, target hole and desired center position offset is conversed through actual measurement, if detect aperture is apart from overproof, with the round file cutter with target hole same size, filing finishing is carried out to bottom outlet sidewall, remove trim amount with round file cutter respectively in two reference directions of this bottom outlet wall, trim part should be connected smoothly with bottom outlet circular arc, makes detect aperture apart from the margin of tolerance.
3rd step, reaming, selects suitable drill bit to carry out reaming and chamfering, then reams with thick, finishing reamer, deburring, chamfered edge.
Operation of the present invention is simple, positional precision is high, and can increase economic efficiency.
