Description
Technical field
This utility model is related to a kind of brake motor bias axis machining apparatus.
Background technology
ESC is ESP control system（Electronic Stability Control）, it is that a kind of automobile leads
Gravitation control system, compares with other TCSs, and ESC not only controls driving wheel, and controllable driven pulley.As after
The excessive situation of steering that wheel drive vehicle often occurs, now trailing wheel is out of control and whipping, ESC will stop slow outside front-wheel stablizing
Car；When turning to very few, in order to correct tracking direction, ESC then can stop slow inner rear wheel, so as to correct travel direction.ESC is to mistake
Degree is turned to or understeer is especially sensitive, can rapidly be identified this dangerous situation and be made a response rapidly, is accurately done
Pre- mode of braking, travels on correct track and prevents defective steering stabilizer with making vehicle safety.In case of emergency, ESC can be with
Automatically single wheel is braked, and stable tire actively protects person for driving a car to prevent from overturning, it may be said that ESC is at present most
The representative of advanced active safety technologies.
Automobile brake motor eccentric shaft is the core component of ESC system, plays balanced action, makes electromotor operating more stable,
Vibration and noise are reduced, dimension precision requirement is higher.Existing eccentric shaft processing typically increases adjustment folder on machine tool chief axis
Tool is carried out, and it is poor to easily cause homogeneity of product, and processing cost is expensive, and back work is more, and working (machining) efficiency is low, the technology to workman
Require higher.Therefore, it is necessary to be transformed prior art and optimized.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model to be rapidly completed there is provided one kind
The device of eccentric shaft cutting.
This utility model solves the technical scheme that its technical problem adopted：
A kind of eccentric cutting device of automobile brake motor eccentric shaft, including the live spindle of machining tool, the rotation
The alignment of shafts is provided with pneumatic pull rod, and the live spindle end is fixed with chuck, and the center of the chuck is provided with location hole, institute
State and be provided with location hole eccentric clamping, the eccentric clamping by being threadably mounted on the pneumatic pull rod, the eccentric clamping
Clamping hole center deviation described in eccentric clamping center.
Further, the eccentric clamping is split into three lobes from front end to fixing end, has one gap between adjacent two lobe.
Further, the external diameter of the eccentric clamping is gradually reduced to form a taper from front end to fixing end, the location hole
Inside it is provided with the step that close up can the eccentric clamping of division.
Further, the eccentric clamping is made using the metal material with favorable elasticity.
Further, the eccentric clamping is fixed in the live spindle by a dormant bolt.
The beneficial effects of the utility model are：Eccentric clamping is driven to clamp automatically, unclamp workpiece, fixture using pneumatic pull rod
Without the need for adjustment, back work is few, not high to the technical requirements of workman, working (machining) efficiency and yield greatly improved, it is ensured that product
Concordance, reduce processing cost.
Description of the drawings
This utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structure chart of the present utility model；
Fig. 2 is the right view of Fig. 1.
Specific embodiment
Referring to figs. 1 to 2, a kind of eccentric cutting device of automobile brake motor eccentric shaft of the present utility model, including processing
The live spindle 1 of lathe, the live spindle 1 is provided centrally with pneumatic pull rod 11, and the end of pneumatic pull rod 11 is provided with screwed hole,
The end of the live spindle 1 is fixed with chuck 2 by 6 dormant bolts, and the center of the chuck 2 is provided with location hole 3, described fixed
Position is provided with eccentric clamping 4 in hole 3.
The eccentric clamping 4 is made using the metal material with favorable elasticity, and its front end is provided with clamping hole 41, fixing end
It is provided with the screwed hole of the end of pneumatic pull rod 11 to the external screw thread being adapted to, eccentric clamping 4 is by being threadably mounted at pneumatic pull rod 11
On.
The center of the whole eccentric clamping 4 of center deviation in the clamping hole 41, the external diameter of eccentric clamping 4 is from front end to fixation
End is gradually reduced to form a taper, and three lobes are split into from front end to fixing end, has one gap between adjacent two lobe.
The step 31 that close up can the eccentric clamping 4 of division is provided with the location hole 3 of the eccentric clamping 4.Work as work
When part is put into clamping hole 41, pneumatic pull rod 11 drives eccentric clamping 4 to move backward, and its tapering is stuck at step 31, in pneumatic drawing
Under the pulling force of bar 11, three lobe chucks of division close up rapidly, so as to tightly clamp workpiece, then in the driving of live spindle 1
Lower rotation, the process tool for may move on machining tool, feeding is cut it, and after the completion of cutting, pneumatic pull rod 11 drives
Eccentric clamping 4 is turned right motion, and three lobe chucks of its division quick rebound, so as to unclamp workpiece departing from the restriction of step 31.
Cut by the clamping workpiece of eccentric clamping 4 for calculating, its center is fixed, without the need for adjustment, pneumatic drawing
The Automatic-clamping of bar 11, release, back work is few, not high to the technical requirements of workman, thereby may be ensured that the concordance of product.Quilt
The workpiece of clamping rotates under the driving of lathe live spindle 1 around the center of rotation, and process tool is for linear motion, to workpiece
Carry out cutting and obtain eccentric shaft.The course of processing is simple, significantly reduces the complexity of operation, reduces flow process, improves and adds
Work efficiency rate, reduces processing cost.
The above is better embodiment of the present utility model, but this utility model is not limited to above-described embodiment,
As long as it reaches technique effect of the present utility model with any same or similar means, protection model of the present utility model should be all fallen into
Within enclosing.
