Description
Technical field
The utility model is related to machining tool clamp fields, and in particular to a kind of punching of multi-diameter shaft class part axial
Puncher frock clamp.
Background technology
When the existing puncher for the punching of multi-diameter shaft class part axial punches workpiece, workpiece is installed on fixture
It is fixed, then cutter rotation is processed；But in processing, since the head that fixture only clamps workpiece is processed, work
As soon as the stress surface of part and fixture is integral planar, the case where shifting after the easily appearance of such workpiece is mobile, it can not ensure the steady of processing
Qualitative and product qualification rate；Moreover, there are clamp power is small, the small defect of the stress surface of workpiece and fixture.A kind of fixture
A kind of part can only be often processed, application range is narrow, and fixture manufacturing cost is high.
Utility model content
For the above-mentioned deficiency of the prior art, the utility model provides that a kind of stress surface is big, ladder of high precision machining
The puncher frock clamp that axial workpiece axially punches.
For achieving the above object, the technical solution adopted in the utility model is：
There is provided a kind of puncher frock clamp of multi-diameter shaft class part axial punching comprising fixture, mounting plate and support
Device, fixture are the sector structure of two identical and opposite installations, are provided with step on the inner arc surface of fixture, fixture passes through spiral shell
Bolt is fixedly installed on mounting plate, and inner arc surface identical with fixture is offered on mounting plate and bottom surface is provided with support device,
Molding mounting base in conjunction is provided in support device, mounting base is installed on puncher in corresponding executing agency.
Further, further include workbench, the center of workbench offers through-hole, and the both sides of through-hole offer for support
The perforative long stripes through hole of device.
Further, support device is hydraulic telescopic rod, and hydraulic telescopic rod is connect with the hydraulic device on puncher.
Further, the machining accuracy of fixture is 0.01mm.
Further, step is " C " angular step.
Further, mounting plate is sector structure identical with fixture.
The beneficial effects of the utility model are：Fixture uses two identical sector structures, by the Inner arc of sector structure
Clamping face of the face as clamping workpiece, while step will be provided on clamping face, such fixture can be entire outer with multi-diameter shaft
Surface contacts simultaneously, increases stress surface, increases clamping force；And setting step can effectively prevent workpiece in process
The case where middle retrogressing；The design of " C " angular step can effectively prevent step to be crushed to outer surface of workpiece when clamping force is excessive
The defect of deformation.
Mounting plate is installed in support device, facilitates installs fixture, while keeping fixture installation steady；Hydraulic telescopic rod conduct
Support device, staff can adjust the stroke of hydraulic telescopic rod to adjust the tooling position of fixture；It is opened up on workbench
Through-hole facilitates processing is preceding parts to be processed is put into workbench, and staff can also be according to the needs of workpiece to be processed, to replace
Fixture on mounting plate meets different process requirements；To meet uniform force, the machining accuracy control of fixture 0.01mm with
It is interior.

Fig. 4 is the structural schematic diagram of mounting plate.
Wherein, 1, fixture, 2, workbench, 3, support device, 4, mounting base, 5, " C " angular step, 6, mounting plate, 7, long
Strip through-hole.
Specific implementation mode
Specific embodiment of the present utility model is described below, in order to facilitate understanding by those skilled in the art
The utility model, it should be apparent that the utility model is not limited to the range of specific implementation mode, to the common skill of the art
For art personnel, if various change the attached claims limit and determine the utility model spirit and scope in,
These variations are it will be apparent that all utilize the innovation and creation of the utility model design in the row of protection.
As shown in Figures 1 to 4, a kind of puncher frock clamp of multi-diameter shaft class part axial punching includes fixture 1, fixture
1 is two identical structures and the sector structure of opposite installation, and two opposite inner arc surfaces of fixture 1 are the clamping face of fixture 1, folder
It is provided with " C " angular step 5 on tight face, fixture 1 is installed on by bolt on mounting plate 6, and mounting plate 6 is set as and 1 phase of fixture
With sector structure, be provided with support device 3 on mounting plate 6, mounting base 4, mounting base 4 and support be provided in support device 3
Device 3 is integrally formed, and mounting base 4 is installed on by bolt in the corresponding executing agency of puncher.
In implementation process, workpiece is positioned in the gap formed between fixture 1 this programme, executing agency's band of puncher
Dynamic fixture 1 performs relative motion, and clamping face is contacted with the outer surface of workpiece, generates clamping force, realizes clamping function." C " angular
Rank 5 can help fixture 1 to be contacted well with all surfaces of workpiece, increase the area in clamping face, make clamping force uniform force,
Reduce fixture 1 simultaneously and the injuries such as deformation are crushed to workpiece surface.
This programme is preferred, and support device 3 uses hydraulic telescopic rod, the hydraulic device of hydraulic telescopic rod and puncher to connect,
Staff to adjust the tooling position of fixture 1 and can adjust puncher to workpiece by adjusting the stroke of hydraulic telescopic rod
Allowance；Fixture 1 is opened up on two opposite faces of cuboid it can also be designed to the rectangular parallelepiped structures of two identical and opposite installations
There is arc surface, " C " angular ladder is provided on arc surface, different types of work pieces process demand can be met in this way.
Be additionally provided with workbench 2 under mounting plate 6, the center of workbench 2 offers through-hole, the both sides of through-hole offer for
3 perforative long stripes through hole 7 of hydraulic telescopic rod, workbench 2 are installed on puncher；Before work pieces process, workpiece is positioned over work
On the through-hole for making platform 2, the executing agency of puncher drives fixture 1 to realize that clamping process, the design of workbench 2 are convenient to workpiece again
Staff places workpiece, improves working efficiency.
In conclusion the utility model fully solves the defect of the prior art, design structure is simple, reasonable, cleverly
The mode of ladder is set on the clamping face of being used in, to increase the contact surface of fixture 1 and workpiece, prevents workpiece in process from retreating
The shortcomings that, the personnel of working at the same time can very easily replace the fixture 1 on mounting plate 6, realize the process requirements to different workpieces.
