Description
Technical field
The invention belongs to machining turning process field, particularly relate to a kind of concertina type constant velocity cardan joint end envelope
The method for turning of closed form out star wheel.
Background technology
Constant velocity cardan joint is the key components and parts on automobile, is that a kind of output shaft and power shaft are with the intermittent angle speed equal to 1
Spend the universal joint than transmitting movement.Constant velocity cardan joint by service behaviour divide can centered by fixed pattern and concertina type, by the car
Installation form and outer shape can be divided into again endcapped type, axle sleeve type, flange-type, wheel type etc..Wherein VL type belongs to and stretches
Contracting, flange-type constant velocity cardan joint, because of its have that simple in construction, size be little, light weight but the high advantage of life-span length, intensity be by extensively
Use.Along with developing rapidly of automobile industry, the out star wheel in VL type universal joint there occurs branch, occurs in that endcapped type
Out star wheel, because of its simple installation, development is increasingly faster, the out star wheel trend of big substituted flange-type.
The method for turning of this endcapped type out star wheel is substantially: 1. with milling flat drill centers special equipment
Milling flat drill centers；2. numerically controlled lathe turning；3. numerical control lathe wheeled litter large end face and endoporus.The drawback of this kind of processing mode
It is milling flat drill centers operation, first, because of the abrasion in the course of processing of the centre drill in modular cutting tool assembly and blade not
With, cause depth of center hole fluctuation big, size is difficult to control to, and need to often be adjusted, second, because using single movable V-block folder
Tight shank cylindrical, adds the clamping and positioning mode compressing intermediate step face, and clamping concordance is poor, causes centre bore inclined, road after impact
The allowance of operation is uneven, even there will be the phenomenon that car does not goes out, and has a strong impact on the life-span of blade, finally, three
In procedure, the first two procedure all uses black skin to be clamped location, has run counter to the selection principle of Vehicle Processing benchmark, product matter
Amount fluctuation is big, and the particularly form and position tolerance such as beating degree is overproof.
Summary of the invention
The invention aims to solve above-mentioned technical problem, it is provided that a kind of concertina type constant velocity cardan joint endcapped type
The method for turning of out star wheel, coordinates numerically controlled lathe by frock, it is achieved processing accurate to out star wheel, it is ensured that crudy
And automaticity.

Detailed description of the invention
The method for turning of concertina type constant velocity cardan joint endcapped type out star wheel of the present invention, including following operation:
(1) by claw using endoporus as clamping face, endoporus bottom surface is as locating surface, by the end of top fixing axis body, right
Axis body outer surface carries out rough turn；
(2) with the axis body surface of rough turn mistake as clamping face, using the way station terrace of axis body and blind hole as locating surface, finish turning blind hole
Outer surface and endoporus；
(3) endoporus crossed using finish turning is as clamping face, blind hole outer surface as positioning clamping workpiece, the outer surface of finish turning axis body,
The end face of axis body and centre bore.
See accompanying drawing 1, be not turning bottom the endoporus of concertina type constant velocity cardan joint endcapped type out star wheel, its remaining part
Divide and be required for reaching dimensional requirement and precision by turning.Turning part includes the inner hole surface of blind hole, outer surface and axis body
Outer surface, centre bore and end face.
Seeing accompanying drawing 2, the first step is rough turn cylindrical: using forging endoporus as clamping face, and endoporus bottom surface is as locating surface, same
Shi little Duan withstands with top, rough turn cylindrical, removes major part cylindrical surplus, and provides essence benchmark for following process.
Thick cylindrical turning process uses the mode on folder one top to carry out turnery processing, and the inner hole sleeve of workpiece 24 is at rough-turning clamp
Front end, small end bowl-type top 6 is withstood, and is made the endoporus bottom surface of workpiece 24 be adjacent to the positioning head 5 of rough-turning clamp front end, lathe oil
Cylinder promotes push-pull bar 3 to be moved along, and the inner hole wall promoting 3 claws 4 to clamp workpiece 24 outward realize the clamping of workpiece 24 with
Location, can be automatically performed the excision of band grid lines region material in workpiece 24 by turning operation.Because of used be that bowl-type is top
6, Gu workpiece 24 small end head has one section cannot process, fine turning outer circle operation can be left to and machine in the lump.After machining, machine
Bed oil cylinder post-tensioning, can unclamp claw 4, after bowl-type top 6 retreats, can take off workpiece 24.
See accompanying drawing 3, second step, finish turning endoporus: using the big cylindrical of rough turn mistake as clamping face, way station terrace is as fixed
Position clamping workpiece, finish turning large end face and endoporus.
Frock used by finish turning endoporus operation is collet chuck, and there is a cone cylinder 14 front end of collet chuck, is inside provided with an elastic expansion-sleeve 15,
Elastic expansion-sleeve 15 is connected with disc type pull bar 7 further through coupling body 11, and benchmark cushion block 12 is used screw by 3 contour pads 9 and is connected
Dish 8 connects, it is ensured that benchmark cushion block 12 is axially without motion, and benchmark cushion block 12 front end is connected by screw locating piece 13, workpiece 24
After small end stretches into collet chuck, lathe oil cylinder post-tensioning, moves, in cone cylinder 14 after driving elastic expansion-sleeve 15 by disc type pull bar 7, coupling body 11
The endoporus of the lower elastic expansion-sleeve 15 of effect reduce, embrace the big periphery of workpiece 24, simultaneously axially moving to left because of elastic expansion-sleeve 15,
Workpiece 24 can be adjacent to locating piece 13, it is achieved the clamping of workpiece 24 and location, can be automatically performed in workpiece 24 by turning operation
Excision with grid lines region material.After machining, push away before lathe oil cylinder, elastic expansion-sleeve 15 can be unclamped, take off workpiece 24.
See accompanying drawing 4, the 3rd step, fine turning outer circle: the endoporus crossed using finish turning is as clamping face, and large end face is as positioning clamping
Workpiece, fine turning outer circle, small end face and centre bore.
Frock used by fine turning outer circle operation is lathe finish fixture, and main body 18 front end of lathe finish fixture is tapered, and outside is cased with
The collet 22 that endoporus is tapered, has a pulling plug 23 to be connected with rod head 17, pulling plug 23 front end and spring in main body 18 hole
Chuck 22 contacts, and connecting in main body 18 has a positioning block 21, by the inner hole sleeve of workpiece 24 at the outside of collet 22, lathe
Oil cylinder post-tensioning, by rod head 17 and pulling plug 23, moves after can driving collet 22, under the effect of tapering, and collet
22 cylindricals swell, the endoporus of clamping workpiece 24, and moving to left because of collet 22, can be adjacent to locating piece 21 by workpiece 24 simultaneously, real
The clamping of existing workpiece 24 and location, can be automatically performed the excision of band grid lines region material in workpiece 24 by turning operation.Add
After work completes, push away before lathe oil cylinder, by push rod 19, anti-rotation ring 20, collet 22 can be promoted to unclamp, take off workpiece 24.
Below it is only the preferred embodiment of the present invention, it is noted that for those skilled in the art,
Without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as this
Bright protection domain.
