Abstract
The invention relates to a method for clamping axle element, wherein it is characterized in that: first, measuring two end distance of work piece at free state; putting work piece between two top sharps, while one is mounted on movable top sharp base; two ends of work piece are mounted with flange discs fixed via nuts to contact the sharp with central hole; measuring two ends distance compared with free state, adjusting position of movable top sharp base, to correct them same, fixing movable top sharp, and processing the work piece. The invention can avoid flexible curvature in treatment to improve accuracy. And the distance measurement can utilize laser measurer.
Description
Technical field
The invention belongs to machining methods, specifically is a kind of clamp method of axial workpiece.
Background technology
When a lot of axle classes or similar Machining of Shaft-type Parts, must locate with two centre bore, and need apply an axial force at the part two ends usually, the top clamping of general employing, and make top and part centre bore applying back processing, but when being slender axles or flexible part, part is easy to make part to produce elastic bending in the clamping process, cause the dimensional accuracy and the form tolerance of part to be difficult to control, influence part processing precision.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of advantages of simple is provided, can effectively controls elastic bending after the thin and long units clamping, improves the clamp method of the axial workpiece of machining accuracy.
Technical scheme of the present invention is as follows:
A kind of clamp method of axial workpiece is characterized in that: measure the distance at two ends under the workpiece free state earlier, again workpiece is withstood on two top between, one of them top being contained on the rolling center seat, ring flange is loaded onto at the workpiece two ends, screws with nut respectively, makes top and the applying of workpiece centre hole, the distance at measuring workpieces two ends, and with free state under compare, adjust the position of rolling center seat, consistent under the distance that makes the workpiece two ends and the free state, fixedly the rolling center seat gets final product processing work.
The distance at measuring workpieces of the present invention two ends can adopt laser range finder, promptly loads onto laser beam emitting head and laser perflectometer respectively at the workpiece two ends, removes laser beam emitting head and laser perflectometer after adjustment fixes.
Workpiece of the present invention withstands on two concrete grammars between top: the workpiece two ends respectively have one top, be contained on the dead head respectively, wherein an end dead head is fixed, the other end is the rolling center seat, and the rolling center seat can move axially along workpiece, a step is respectively arranged on top, have a nut be contained in top on, nut inner hole has a step, between nut step and the top step plane bearing is arranged, the threads engaged on nut and the ring flange.
Slender axles of the present invention add man-hour owing to measure the distance at workpiece two ends earlier, fix with ring flange and nut with two ends after the top clamping, the distance at measuring workpieces two ends again, and through the adjustment of rolling center seat make with former free state under fixing after consistent, adopt this method holding workpiece, making can be not crooked in the thin and long shafts part process, improves the machining accuracy of axial workpiece.The present invention adopts laser range finder, makes measurement more simple and convenient.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
The specific embodiment
A kind of clamp method of axial workpiece, as shown in Figure 1, it is characterized in that: the distance of measuring two ends under workpiece 1 free state earlier, again workpiece is withstood between two top 5, one of them top being contained on the rolling center seat 6, ring flange 2 is loaded onto at the workpiece two ends, screw with nut 8 respectively, fitted in top and workpiece centre hole, the distance at measuring workpieces two ends, and with free state under compare, adjust the position of rolling center seat 6, consistent under the distance that makes the workpiece two ends and the free state, fixedly the rolling center seat 6, get final product processing work.
The specific embodiment of the invention following (as shown in Figure 1): A, load onto ring flange 2 respectively at workpiece 1 two ends, ring flange 2 is fastening with workpiece, and load onto the laser beam emitting head 3 and the laser perflectometer 4 of laser range finder respectively at two ends, measure the distance under the free state of workpiece two ends; B, workpiece two ends respectively have one top 5, be contained on the dead head, an end is a stationary center seat 11, and the other end is a rolling center seat 6, rolling center seat 6 can move axially along workpiece 1, a step 7 is respectively arranged on top 5, have a nut 8 to be contained on top 5, nut 8 endoporus have a step 9, one plane bearing 10 is arranged between nut step 9 and the top step 7, threads engaged on nut 8 and the ring flange 2, fastening nut 8 makes top and fit in the workpiece centre hole; C, measure the distance between laser beam emitting head 3 and the laser perflectometer 4, compare with distance under the free state, mobile rolling center seat 6 makes under distance and the free state between laser beam emitting head 3 and the laser perflectometer 4 apart from consistent; D, fixing rolling center seat 6, and pull down laser range finder, can be at processing work under the clamp position.
