Abstract
The invention discloses a technique for machining cylindrical surfaces on small spheres. The technique comprises bonding, centerless grinding, heat treatment, bench work and cleaning, wherein the bonding includes that the two small spheres are bonded together with epoxy resin glue and a special tool; the centerless grinding includes that the cylindrical surfaces are machined on the small spheres through a centerless grinding machine; the heat treatment includes that the parts are tempered for 2.5 h at a low temperature of 140+/-15 DEG C; the bench work includes that residual glue on the small spheres includes cleaned; and the cleaning includes that the small spheres are subjected to ultrasonic cleaning. The tool for bonding in the technique for machining the cylindrical surfaces on the small spheres comprises a base plate and a forming template, wherein a series of small sphere positioning holes are formed in the forming template. According to the method, the two small spheres are bonded together, a straight line passing through the centers of the small spheres is naturally formed by virtue of the two points of the centers of the small spheres, the machining of the cylindrical surfaces on the two small spheres can be finished at a time according to the self-centering working principle of the centerless grinding machine, the technique is easy to realize, and a new method is provided for machining of other like parts.
Description
Technical field
The invention belongs to processing technique field, particularly a kind of on bead processing column faceProcess.
Background technology
On bead, process a high accuracy circular cylinder, because bead hardness is high, face of cylinder essenceSpend highly, need grinding just can reach size and roughness requirement. But due to the small ball's diameter veryLittle, cannot clamping and location.
Adopt traditional thinking, bead is bonded in a clamping rod, owing to being difficult to beadThe centre of sphere overlaps with the excellent center line of clamping, and when grinding, the face of cylinder is asymmetric, and easily comes off.
Adopt traditional processing thought and method, waste time and energy, and be difficult to process on beadThe qualified face of cylinder.
Summary of the invention:
Goal of the invention of the present invention is the difficult point that is difficult to the processing of clamping location for bead, and design is carriedFor a kind of on bead the process of processing column face, with one group of special tooling, little by twoBall links together with glue, then adopts the technique of centerless grinding, two bead centre of sphere natural shapesBecome an axial line, with centerless grinder processing, do not need to clamp part, guided by guide wheelComplete face of cylinder processing.
The technical solution used in the present invention is, a kind of on bead the technique side of processing column faceMethod, work flow comprises, bonding, centreless grinding, heat treatment, pincers worker, cleans, specifically stepRapid as follows:
Step 1: processing bead adhesive tool
Described frock comprises that base plate 1 and the forming panel 2 of placing on it form; Forming panelThe bead locating hole 3 of uniform multiple same specifications on 2, bead locating hole 3 is through hole, its apertureMatch with the diameter of 1 bead, clearance control within 0.005mm, bead locating hole 3Perpendicular to forming panel 2 bottom surfaces, the thickness gauge of the degree of depth of bead locating hole 3 and forming panel 2Very little identical, the gauge of forming panel 2 should make to be vertically placed on two in bead locating hole 3Gap between individual bead is within 2-2.5mm;
Step 2: bonding bead
Base plate 1 horizontal positioned, places forming panel 2 on base plate 1; At bead locating holeIn 3, first put into after 1 bead toward locating hole 3 injecting glues, when glue identity distance is from locating hole 3 apertures1 millimeter time, stop injecting glue, then in locating hole 3, put into the bead of another 1 same specification, after putThe upper extreme point of the bead entering is concordant with the end face of forming panel 2; Remove overflow locating hole 3 more thanGlue, placed after 5-6 hour, and two beads that bond together are taken out;
Step 3: the grinding bead face of cylinder
Two beads that bond together are carried out to centreless grinding method and process, add man-hour littleThe face of cylinder of ball must once be ground to the size that machining needs;
Step 4: cleaning bead
Complete after processing, in 8 hours, the part processing is carried out to lonneal and cleaningClean remaining glue processing.
Preferably, the bonding bead process described in step 2, operating temperature need to remain onBetween 19-20 DEG C.
Preferred base plate 1 and forming panel 2 adopt fluoroplastics material.
Technique effect of the present invention, compared with original processing method, uses the present invention, little by twoBall bonds together, and utilizes two points of the centre of sphere, and self-assembling formation is crossed the straight line of the centre of sphere, adoptsCenterless grinder self-centering operation principle, once can complete the processing on the face of cylinder on two beads,Avoid the problem that general thinking is difficult to clamping location, the part processing by the method, circleCylinder dimensional tolerance in 0.01mm, surface roughness Ra 0.8, the method processing is reliableProperty is high, and quality is high, with short production cycle, has significantly promoted working (machining) efficiency, has reduced production costAnd labour intensity, for the processing of other like parts provides a kind of new method.

Detailed description of the invention
In order better to implement the inventive method, below in conjunction with Figure of description to the inventive methodElaborate, refer to Figure of description 1,2,3,4.
An instrument for bonding use on bead in the processing method of processing column face, comprising:Base plate 1 and forming panel 2.
Described forming panel 2 bottoms and plate top surface laminating, be provided with one in described forming panel 2Series bead locating hole 3, the interior placement bead 4,6 of described bead locating hole 3 and glue; DescribedBead locating hole 3 matches with the diameter of bead 4,6, and clearance control is at 0.005mm.
In the gauge of described forming panel 2, bead locating hole is perpendicular to bottom surface, forming panelGlue 5 layer thicknesses between gauge guarantee bead 4,6 are between 2-2.5mm.
In use procedure, base plate 1 is placed on workbench and is set level, forming panel 2 is placed onOn base plate 1, bead 4 is put into bead locating hole 3, suit with base plate 1 end face, thenGlue 3 is put into bead locating hole 3, then bead 6 is put into bead locating hole 3, ensureBead 6 upper extreme points are concordant with forming panel 2 end faces, remove the remaining glue overflowing, and place 5-6 littleShi Hou, takes out the bead bonding together 4, glue 5, bead 6, takes out part as Fig. 2Schematic diagram.
