Description

Synchro converter ring tooth holder
Technical field
The utility model relates to a kind of machining tool of automobile synchro converter ring, specifically a kind of synchro converter ring tooth holder.
Background technology
At present, the wall thickness of synchro converter ring key internal diameter and inner conical surface thinnest part is 1.5 ~ 3.5mm, beats within 0.1 ~ 0.15mm relative to inner conical surface axial line benchmark on ring gear reference circle, and the circularity of inner conical surface requires in 0.02 ~ 0.04.The conventional brace of existing employing is block formula of the carving collet chuck of lathe dispensing, its clamping mode is radial force, after turning, inner conical surface rebound deformation is triangle or elliptical shape, inner conical surface circularity must be greater than 0.1, finally can not ensure the key property of product key: as the angle of the conical surface, circularity, tooth runout, the lock flank of tooth beat, large end face beats.
Utility model content
The purpose of this utility model is to provide a kind of fixture for processing synchro converter ring product.
To achieve these goals, the utility model is by the following technical solutions:
Synchro converter ring tooth holder comprises terminal pad, float support dish, clamp body, stop pin, workpiece pull bar, lining, work clamp, tooth shape locating circle, guide pad, supporting disk briquetting, float spherical pull bar and main shaft pull bar; Terminal pad is connected with clamp body; Float support dish is connected with supporting disk briquetting, and clamps floating spherical pull bar; The spherical pull bar that floats is connected with machine tool chief axis pull bar; Guide pad and tooth shape locating circle are fixed on clamp body; Work clamp is fixed on workpiece pull bar; Workpiece pull bar is placed in lining; Lining stop pin is connected with clamp body.
Technique scheme adopts floating clamp, and during profile of tooth is fixed, end face compresses, and thrust acts on end face, ensure that product circularity, tooth runout, the lock flank of tooth are beated, the requirement of beating of large end face.
Further improvement is: described floating spherical pull bar adopts the bulb point cantact that floats to be connected with supporting disk briquetting with float support dish.Because the spherical pull bar of floating adopts bulb to float point cantact, ensure that the pressure of work clamp application point is equal, is namely in distance product big cross section sustained height plane, and thin-walled ring is even at axially loaded, and inner cone circularity is qualified, prevents synchronous ring end face unbalance stress.
Further improvement is: one end and the work clamp of described workpiece pull bar are fastening, and the other end hangs on float support dish; The workpiece pull bar one end that is connected with float support dish is flat structure.Function due to workpiece pull bar often processes 1 product, must move once by commute, so be consumable accessory, must convenient and swiftly replace.When replacing, unclamp stop pin, turning of work piece pull bar, takes off work clamp, and employing flat structure is conveniently taken out by workpiece pull bar behind the direction in order to rotational workpieces pull bar.
Effect of the present utility model is: adopt profile of tooth floating clamp, center with profile of tooth, thrust acts on end face, the mode converted products that end face compresses, product axially loaded, ensure that the crucial key property of synchro converter ring product conforms to quality requirements, the synchro converter ring reliable product quality of processing.

Detailed description of the invention
Below, by reference to the accompanying drawings the utility model is further described:
As shown in Fig. 1 ~ Fig. 5, the utility model comprises terminal pad 1, float support dish 2, clamp body 3, stop pin 4, workpiece pull bar 5, lining 6, work clamp 7, tooth shape locating circle 8, guide pad 9, supporting disk briquetting 10, float spherical pull bar 11, main shaft pull bar 13.Terminal pad 1 is connected with clamp body 3 by screw; Float support dish 2 is connected by screw with supporting disk briquetting 10, and clamps floating spherical pull bar 11; The spherical pull bar 11 that floats is connected with machine tool chief axis pull bar 13 by nut 12; Guide pad 9 is fixed by screws on clamp body 3, leads to floating spherical pull bar 11; Tooth shape locating circle 8 is fixed by screws on clamp body 3; Work clamp 7 is fixed by screws on workpiece pull bar 5, and one end of workpiece pull bar 5 and work clamp 7 are by screw fastening, and the other end hangs on float support dish 2; Workpiece pull bar 5 is placed in lining 6, and lining 6 is connected with clamp body 3 by stop pin 4; Stop pin 4 prevents workpiece pull bar 5 from rotating direction of rotation, causes work clamp 7 to unclamp.Work clamp 7 and tooth shape locating circle 8 form the clamping to workpiece 14.
During work, spindle of numerical control lathe pull bar 13 is connected with oil (gas) cylinder, and cylinder piston moves, and drives the clamping of tapering chuck and unclamps.The spherical pull bar 11 that floats forms overall under the effect of the power of main shaft pull bar 13 with float support dish 2, supporting disk briquetting 10, workpiece pull bar 5, and left and right rectilinear motion, drives work clamp 7 clamp and unclamp synchronous ring product.Work clamp 7 has three application points at least, and three application points are in the uniform height plane of distance synchronous ring large end face, equal to ensure the pressure of pressing plate.Lathe piston retraction, work clamp 7 compresses synchronous ring, turning inner conical surface; Lathe piston opens, and unclamps synchronous ring, takes next part of clamping.
The function of workpiece pull bar 5 often processes 1 product, must move once by commute, so be consumable accessory, must convenient and swiftly replace.When replacing, unclamp stop pin 4, turning of work piece pull bar 5, take off work clamp 7, behind the direction of rotational workpieces pull bar 5, workpiece pull bar 5 is taken out.Flat structure in the A-A view of Fig. 3 is conveniently taken out after outwarding winding.
The spherical pull bar 11 that floats can move linearly left and right, float support dish 2, workpiece pull bar 5, work clamp about 7 is driven to move linearly, there are cumulative errors in the fabrication process in these part dimensions, because the spherical pull bar 11 that floats adopts the bulb point cantact that floats to be connected with supporting disk briquetting 10 with float support dish 2, ensure that the pressure of work clamp 7 three application points is equal, namely be in distance product big cross section sustained height plane; thin-walled ring is even at axially loaded; inner cone circularity is qualified, prevent synchronous ring end face unbalance stress.
The lock flank of tooth of tooth shape locating circle 8 positioning synchronous ring, the inner conical surface of converted products.During detection, tooth runout, beat, large end face is beated lock be all with inner conical surface position benchmark by the flank of tooth.Because machining benchmark and Product checking benchmark can be unified to exchange, decrease measure error.
The product quality contrast table that existing chuck clamps and the utility model are processed
Therefore, the inner conical surface processing of synchronous ring thin-wall part, existing chuck clamps is radial force, inner conical surface rebound deformation after turning, can not ensure that the product quality of processing reaches requirement; And the utility model is axially loaded, adopt floating clamp, during profile of tooth is fixed, end face compresses, and thrust acts on end face, ensure that product circularity, tooth runout, the lock flank of tooth are beated, large end face beats requirement, the reliable product quality of processing.
