Its axial location is fixed at one tip 46, thus by the fixation of forward and backward, is completed positioning and the fixation of the workpiece, is entered
And operation is processed to which in application milling cutter 48.
This work holder, with simple structure, maneuverable advantage.But this clamping device, also has one
Shortcoming, precisely due to which positions block size fixing, therefore which has that connects a precision.
Specifically, as work pieces process all has certain margin of tolerance, the size of workpiece can be in its size sometimes
The upper limit of tolerance is sometimes in lower limit, sometimes moderate.Therefore, the workpiece of processing is finally completed, and its size is larger sometimes,
Sometimes again can be smaller.This for workpiece itself, due to, all in dimensional tolerance range, therefore, being all qualified.
But this is for clamping and fixing device, as its size for connecting block 42 is fixed, this change in size, meeting
Which is had a significant impact.
For example, if the positioning block size of clamping and fixing device, it is the tolerance dimension for being in the workpiece fluting for connecting therewith
Middle.At this moment, the processing workpiece for connecting with which, if the size of its fluting, is the intermediate sizes for being in the margin of tolerance, then can compare
Suitably withstood by the locating piece；If bigger than normal, collecting gap just occurs；And if less than normal, it is likely that house very tightly,
Even can not house in which.
Therefore, it is necessory to developing a kind of clamping and fixing device of new workpiece, overcome of the prior art lacking
Fall into.

Further, wherein described locating piece be used for mating portion configuration include triangle body configuration, five side body configurations, six
One kind in the body configuration of side, its profile width are that direction axially extending along which gradually increases.
Further, accepting groove is provided with wherein described first positioning seat, for housing the locating piece, the positioning
Block can be moved axially in the accepting groove.
Further, spring is contained in wherein described accepting groove, which is in the bottom of the accepting groove and the positioning
Between block.
Further, the locating piece also includes outer stopper, and which is connected with the mating part, and is arranged on the collecting
Outside groove, for preventing the locating piece from coming off from the accepting groove.
Further, the axis of wherein described locating piece and the top tip part and workpiece to be fixed, three are positioned at same
On one axis.
Relative to prior art, the utility model has the advantages that：A kind of workpiece that the utility model is related to
Fixing device, the profile width of the main body configuration of its locating piece mating part adopt taper design so which can be suitable for and be coupled to
Various sizes of workpiece fluting in the margin of tolerance, is not in have workpiece on business difference size is slightly smaller, and the problem that can not be connected；
Or workpiece on business difference size is slightly larger, and the problem for occurring connecting gap.
In addition, its locating piece also can further be conducive to which to connect using the removable collecting design in positioning seat
Effect.

Specific embodiment
A kind of technical scheme of the fixing device of workpiece the utility model being related to below with reference to Figure of description is made
Further detailed description.
Refer to shown in Fig. 1, one of the present utility model embodiment there is provided a kind of fixing device of workpiece, which wraps
Include workbench 10.The front-end and back-end of wherein described workbench 10 are respectively arranged with the first positioning seat 12 and the second positioning seat 13.
It is used for arranging workpiece to be fixed 20 between two positioning seats.
Locating piece 14 is provided with wherein described first positioning seat 12, which slides to match somebody with somebody and is connected in first positioning seat 12
In accepting groove 16, in the accepting groove 16, spring 18 is additionally provided with, to push up the locating piece 14 to a certain extent
Go out 16 certain distance of the accepting groove, to facilitate which and connect connecting between workpiece.
Further, the locating piece 14, which includes mating part 142, receives for connecting the front end for withstanding on workpiece to be fixed
In tank, its width gradually increases from its leading section to its direction for extending, i.e., which has certain taper so that its different position
Put, the fluting internal diameter of different width dimensions can be corresponded to so that its closely can connect whole interior in the margin of tolerance
The fluting of footpath size, expands its scope of application.Behind the mating part 142, outer stopper 144 is also associated with, which is arranged on described
Outside accepting groove 16, to prevent the locating piece 14 from departing from from the accepting groove 16.
Second positioning seat 11, its top are provided with top tip part, for withstanding on the rear end of workpiece to be fixed.
During use, workpiece to be fixed 20 be placed on the workbench 10 the first positioning seat 12 and the second positioning seat 13 it
Between.Wherein its front end fluting 21 houses the mating part 142 of the locating piece 14, and its rear end is then withstood by the top tip part 15.By
There is certain taper on the mating part 142 of the locating piece 14, the profile width of its configuration so which goes for tolerance
In the range of whole fluting internal diameter sizes, and closely can connect.At this moment, the top tip part 15 withstands the workpiece 20 so that its
Move along axis, until the locating piece 14 is retracted to the bottom of the accepting groove 16, and compressed the spring as far as possible
18.So prevent the workpiece 20 from occurring front and back position variation in the axial direction.
