Description
Technical field
This utility model relates to frock clamp field, particularly relates to a kind of frock for processing eccentric shaft。
Background technology
Eccentric shaft refers to the workpiece that cylindrical is parallel and misaligned with the axis of cylindrical, is characterized in transmitting rotation, can also transmit revolution simultaneously。The manufacturing procedure of existing eccentric shaft is various, including saw material, the cutting of each parts of turning, line, grinding (for the first time), machining center (homalocephalus), pincers worker assembling and grinding etc. again, material consumption is relatively larger, turnover period is long, the equipment used is relatively more, and eccentric size is difficult to control to。
Utility model content
This utility model is mainly solving the technical problems that provide a kind of eccentric shaft frock, it is possible to effectively shortens the process-cycle of eccentric shaft, simplifies manufacturing procedure, improves working (machining) efficiency。
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide a kind of eccentric shaft frock, including: bearing device and hold down gag；Described bearing device includes base plate and two supporting plates, and said two supporting plate is fixed on the two ends of described base plate by fixture symmetry；Described each supporting plate all offers the first arc groove, between center and the axle center of described base plate of described first arc groove, is provided with the first eccentric throw；Described hold down gag is positioned at the middle part of said two supporting plate, including pressing plate and the locking member that described pressing plate and base plate is connected as a single entity；The side that described pressing plate is relative with supporting plate offers the second arc groove, is provided with the second eccentric throw between center and the center of the first arc groove of described second arc groove；The two ends of workpiece to be processed are placed in the first arc groove of described supporting plate, and are pressed in the second arc groove of described pressing plate。
In one preferred embodiment of this utility model, described eccentric shaft frock also includes the NC dividing head for described workpiece to be processed carries out circumference graduation at any angle。
In one preferred embodiment of this utility model, described first eccentric throw is identical with the distance of the second eccentric throw。
In one preferred embodiment of this utility model, described fixture includes supporting plate fixed screw and supporting plate alignment pin。
In one preferred embodiment of this utility model, described locking member includes two tie down screws, locking nut and pad；Wherein, one end of described tie down screw is fixed on described base plate, its other end run through described pressing plate and successively sheathed, rotation put described pad and locking nut。
The beneficial effects of the utility model are: this utility model one eccentric shaft frock, and simple in construction is compact, it is simple to install, process and regulate, and the machining accuracy making workpiece is high, and simplified processing process flow process can guarantee that workpiece eccentric orfice machining accuracy。

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model being made apparent clear and definite defining。
Referring to accompanying drawing, this utility model embodiment includes:
Embodiment 1
A kind of eccentric shaft frock, including: bearing device, hold down gag and for workpiece to be processed carries out the NC dividing head 12 of circumference graduation at any angle。
Described bearing device includes base plate 1 and two supporting plates 2；Described base plate 1 is circular, and said two supporting plate 2 is fixed on the two ends of the arbitrary radial direction of base plate 1 by fixture (supporting plate fixed screw 9 and supporting plate alignment pin 10) symmetry。
Described each supporting plate 2 all offers the first arc groove 3, between center and the axle center of base plate 1 of this first arc groove 3, is provided with the first eccentric throw d1。
Described hold down gag is positioned at the middle part of said two supporting plate 2 place linear direction, including pressing plate 4 and locking member；The side that described pressing plate 4 is relative with supporting plate 2 offers the second arc groove 8, and is provided with the second eccentric throw d2 between the center of the center of the second arc groove 8 and the first arc groove 3, and makes d2 and d1 equal；Described locking member includes two tie down screws 5, locking nut 6 and pad 7, and one end of described tie down screw 5 is fixed on base plate 1, and its other end runs through pressing plate 3 and locking nut 6 is put in sheathed pad 7, rotation successively。When the two ends of workpiece to be processed 11 are placed in the first arc groove of supporting plate 2, and by, after NC dividing head 12 adjusts angle, screwing locking nut 6, make the second arc groove of pressing plate 4 block and lock workpiece, carry out follow-up processing。
After utilizing above-mentioned frock, the process operation process simplification of eccentric shaft is saw, car, mill, machining center and pincers worker, and process flow is simple and clear, the saving of material, and process time is greatly shortened, it is ensured that while Product Precision requires, efficiency significantly improves。
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model。
