At the preferred aspect of this utility model, the outfan of described motor (2) includes decelerator.
At the preferred aspect of this utility model, described electromagnetic brake (1) is set to dead electricity braking mode.
The technical solution of the utility model also includes: a kind of new tension mechanism, realizes big stroke using lever principle and rises Tight function.By motor, motor fixing seat, electromagnetic brake, ball-screw, feed screw nut, bearing block, lever, supporting table, tensioner Contact and pedestal are formed.Automotive hub is placed on wheel hub processing pedestal, and its centre bore is extended into the tensioner contact of inside Clamping.Tensioner contact is connected through the hinge in one end of lever, and lever is also to be connected through the hinge in supporting table, and supporting table is solid It is scheduled on pedestal.The other end of lever and feed screw nut are attached, and specific connected mode is: install on the end of lever There is a straight pin, runway shaped pin hole is provided with feed screw nut, this straight pin is placed in the pin-and-hole of feed screw nut.Ball Leading screw is fixed between motor fixing seat and bearing block, by Motor drive.The convert rotational motion of motor can be thus The linear motion of feed screw nut, thus promoting lever so as to rotate to an angle, then drive is provided with this of tensioner contact End lever rotates a certain angle.When tensioner contact and fulcrum farther out when, less angle change will produce larger displacement Stroke, thus realize big stroke tensioner function.It should be noted that during wheel hub is processed, needing to be always maintained at Certain expanding force, therefore this utility model are connected with electromagnetic brake in one end of motor, and specific works pattern is dead electricity system Dynamic, that is, when motor power down, motor shaft is held tightly by electromagnetic brake, and the tensioner contact of such lever end just can be locked in certain One position is motionless, thus keeping certain expanding force.Motor output end can choose whether according to specific needs to install and slow down Device.
This utility model typically arranges three tensioner contacts, along automotive hub centre bore circumferencial direction in 120 degree uniformly Distribution, the driver part such as the lever connecting therewith and motor also all arranges three sets, is uniformly distributed in 120 degree on pedestal.
This utility model utilizes lever principle, realizes big stroke tensioner function, can meet the automobile of different specification size The clamping work of centre bore in the machining process of wheel hub, has principle simply, easy and simple to handle, can meet processing request precision etc. Feature.
Brief description
Hereinafter, to describe embodiment of the present utility model in detail in conjunction with accompanying drawing, wherein:
Fig. 1 is the structural representation of the big stroke swelling device for clamping wheel hub centre bore described in the utility model One embodiment.
In figure: 1- electromagnetic brake, 2- motor, 3- motor fixing seat, 4- ball-screw, 5- feed screw nut, 6- bearing block, 7- wheel hub processing pedestal, 8- wheel hub, 9- tensioner contact, 10- lever, 11- supporting table, 12- pedestal.
Specific embodiment
Embodiment 1
Below in conjunction with the accompanying drawings, describe in detail according to the utility model proposes the details of device and working condition.
The utility model proposes a kind of wheel hub is with big stroke swelling device, by motor 2, motor fixing seat 3, electromagnetic brake 1, ball-screw 4, feed screw nut 5, bearing block 6, lever 10, supporting table 11, tensioner contact 9 and pedestal 12 are formed.Automobile Wheel hub 8 is placed on wheel hub processing pedestal 7, and the tensioner contact 9 that its centre bore is extended into inside clamps.Tensioner contact 9 passes through hinge Chain is connected to one end of lever 10, and lever 10 is also to be connected through the hinge in supporting table 11, and supporting table 11 is fixed on pedestal 12 On.The other end of lever 10 is attached with feed screw nut 5, and specific connected mode is: is provided with the end of lever 10 One straight pin, is provided with runway shaped pin hole on feed screw nut 5, and this straight pin is placed in the pin-and-hole of feed screw nut 5.Ball Leading screw 4 is fixed between motor fixing seat 3 and bearing block 6, is driven by motor 2.Thus the rotary motion of motor 2 can be turned Turn to the linear motion of feed screw nut 5, thus promoting lever 10 so as to rotate to an angle, then drive is provided with tensioner and touches 9 this one end lever 10 rotates a certain angle.When tensioner contact 9 and fulcrum farther out when, less angle change will be produced The larger displacement stroke of life, thus realize big stroke tensioner function.It should be noted that during wheel hub 8 is processed, Need to be always maintained at certain expanding force, therefore this utility model is connected with electromagnetic brake 1, concrete work in one end of motor 2 Operation mode is braked for dead electricity, and that is, when motor power down, motor 2 axle is held tightly by electromagnetic brake 1, the tensioner of such lever 10 end It is motionless, thus keeping certain expanding force that contact 9 just can be locked in a certain position.Motor 2 outfan can be according to concrete need To choose whether decelerator is installed.This utility model arranges three tensioner contacts 9, along automotive hub 8 centre bore circumference side Be uniformly distributed in 120 degree, the driver part such as the lever 10 connecting therewith and motor 2 also all arrange three sets, on pedestal 12 It is uniformly distributed in 120 degree.
Test shows, device of the present utility model can meet in the machining process of the automotive hub of different specification size The clamping work of centre bore, it is simple to have a principle, easy and simple to handle, the features such as can meet processing request precision.
