Description
Technical field
The present invention relates to equipments machining die technical field, more particularly to a kind of clamping work for being used to process rotary tapered wedge
Platform.
Background technology
With continuing to develop for car industry, the vehicle of automobile is more and more, and the assembling process of white body is also increasingly multiple
It is miscellaneous.The flange angle of the outer covering piece such as bodywork parts such as beater or beat-up, protecgulum outside plate, bonnet outside plate and roof of many vehicles is most
Negative angle is designed to, to realize the snap-in force of increase stamping parts and improve the purpose of bus body strength.And for the car with negative angle flange
Body parts flanged-edge shaping mould, tapered wedge rotating mechanism utilization can make mould structure simpler.
The advantage of tapered wedge rotating mechanism is to make mould structure simpler, is occupied little space, and structural rigidity is strong, is easy to maintenance to protect
Support, and flanging and restriking part type face and the retainer type face of other parts are smooth smooth in stitching portion, it is to avoid produce on stamping parts
The defects such as raw corrugation；But it has the disadvantage that difficulty of processing is big, machining accuracy quality is difficult to control to, and is particularly rotated on camshaft
Flanging and restriking mould surface portion is difficult to ensure that in assembling using postrotational precision.
For half box type tapered wedge rotating mechanism as shown in Figure 1, rotation protruding shaft 11 two ends are oriented to the knot of slide guide with guide plate
Structure, the rotation bottom surface of protruding shaft 11 and half box type rotating basis 12 are slidably matched rotation；The rotation protruding shaft of this kind of half box type rotary tapered wedge
Both sides can add standby technique block when making full mold, therefore when carrying out the processing of protruding shaft type face, it is impossible to rotational circle will be completed
The rotating basis 12 of curved face processing and rotation protruding shaft 11 are assembled together processing, and then cause such tapered wedge rotating mechanism protruding shaft
Processing is extremely difficult, it is necessary to which every protruding shaft all accordingly makes a machining mould, and cost is high and easily causes machining deviation very
To scrapping, such as clamp shakiness and also easily cause serious accident.
At present, for half box type tapered wedge rotating mechanism rotation protruding shaft processing, using rotation protruding shaft 11 and rotating basis
The mode of 12 separate machineds, organizes vertical assembling and uses again after machining respectively, i.e., after the completion of the rotational circle curved face processing in protruding shaft,
Using the Special mould fixed clamp of custom fabricated, the processing in protruding shaft upper overturning shaping type face is then carried out, will finally be processed
Rotation protruding shaft 11 after is used with the assembling of rotating basis 12.
From the foregoing, it will be observed that existing rotary tapered wedge is in processing, its every protruding shaft is required to make special machining mould respectively,
Fixed clamp during for processing, the machining mould does not have other use after machining, and is disposable processing clamping device,
This kind of processing mode cost is higher, and clamping shakiness also easily causes serious accident；Meanwhile, the flanging and restriking type in protruding shaft
Face and rotating basis separate machined, then assembling, which is placed in the circular arc of rotating basis, uses；Because rotary tapered wedge is to machining accuracy
It is required that higher, protruding shaft and rotating basis requirement have identical machining benchmark, and then separate machined is assembled this kind of mode and easily occurred
Accuracy error, causes Product Precision not up to standard, stamping parts is unqualified during rotating flanging shaping.
Therefore it provides a kind of clamping workbench for being used to process rotary tapered wedge, to which Multiple Type protruding shaft can be realized
It is general, processing cost is reduced, and ensure the assembly precision of the protruding shaft and rotating basis machined, stamping parts qualification rate is improved,
The problem of just turning into those skilled in the art's urgent need to resolve.
The content of the invention

Embodiment
The core of the present invention is to provide a kind of clamping workbench for being used to process rotary tapered wedge, to realize a variety of types
Number protruding shaft it is general, reduce processing cost, and ensure the assembly precision of the protruding shaft and rotating basis machined, improve stamping parts
Qualification rate.
In order that those skilled in the art more fully understands technical scheme, below in conjunction with accompanying drawing to this hair
It is bright to be further detailed.
Fig. 2 is refer to, Fig. 2 is clamping a kind of structural representation of embodiment of workbench provided by the present invention.
In a kind of embodiment, clamping workbench provided by the present invention is used to process rotary tapered wedge, the clamping
Workbench includes offering circular groove on pedestal 21, the pedestal 21, and the bottom of the circular groove is provided with bottom
Support block 22, its two ends are respectively arranged with end support block 23, and protruding shaft to be processed is fixed on the bottom support block 22；The bottom
Portion's support block 22 is the first arc surface towards the face of the circular groove, and the end support block 23 is recessed towards the circular arc
The face of groove is second arc surface concentric with first arc surface, the radius of first arc surface and second arc surface
Radius it is equal, and two arc surfaces radius be less than the circular groove radius.
Specifically, above-mentioned bottom support block 22 has two, thickness side of the bottom support block 22 described in two along the pedestal 21
To setting, to ensure to support reliability.It is apparent that the number of bottom support block 22 can also be determined according to actual use situation,
Such as can be four, six；One bottom support block 22 can also be only set in the thickness direction of pedestal 21.
In order to improve the connection reliability and convenience of protruding shaft and bottom support block 22, it can be set in bottom support block 22
Thread Pilot hole is equipped with, the protruding shaft to be processed is fixed on the bottom support block 22 by the thread Pilot hole.
In theory, protruding shaft is also not limited to be installed on bottom support block 22 by thread Pilot hole, as long as can be real
Both existing reliable locations, for example, can also set neck in bottom support block 22, protruding shaft is installed in the neck.
The number of above-mentioned end support block 23 is preferably that the often end of four, i.e. circular groove is provided with two end supports
Block 23, sets with thickness direction of the end support block 23 along the pedestal 21 described in the two of end, so, can either ensure supportive
Can, pedestal 21 intensity of itself is not interfered with again.
In the course of work, the radius identical protruding shaft with circular groove is placed in in pedestal 21 and fixed, bottom support
Rotation arc surface of second arc surface of the first arc surface of block 22 and end support money with protruding shaft is engaged, and protruding shaft is risen
To support fixation；Processing clamping workbench is fixed on to the type face that can carry out rotating protruding shaft on lathe after the completion of fixation
Processing, because processing clamping workbench fixed clamp effect is similar with the wedge pedestal 21 on rotation wedge, is processed
Into assembling in use, can ensure that assembly precision is consistent, and then ensure the precision quality of product rotating flanging shaping.
Further, bottom support block 22 and end support block 23 are removably mountable to the pedestal 21；So, exist
