Description
Technical field
The utility model belongs to the machining field of precise thin-wall frame work metal, relates in particular to a kind of use
In the milling clamper for reducing thin-wall frame frame clamping deformation.
Background technology
Precise thin-wall frame clsss workpiece process shows that influenceing the origin cause of formation of its crudy has blank residual stress again
Deformation caused by distribution, deformation caused by cutting heat, deformation caused by cutting force, deformation caused by clamping etc., wherein it is main because
Element is clamping deformation.Because workpiece wall is thin, poor rigidity, clamped position and clamping force parameter selection are improper, easily produce clamping and become
Shape.
Utility model content
The utility model is directed to above-mentioned deficiency, there is provided and it is a kind of simple in construction, it is easy to use to be used to reduce thin-walled
The milling clamper of framework clamping deformation.
To achieve these goals, the technical solution of the utility model is：
It is a kind of to be used to reduce the milling clamper of thin-wall frame frame clamping deformation, including clip base, set in described clip base
There is stud, described stud is located at clip base center, and stud runs through whole clip base, and described clip base is provided with
Alignment pin, and alignment pin has two, two alignment pins are located at the both sides of clip base respectively, and alignment pin some insertion folder
Having in matrix, pressing plate is provided with the upside of described alignment pin, described pressing plate center is provided with screw, and described stud runs through screw,
And the upper end of pressing plate is provided with nut, described nut clamping platen.
Further, described clip base bottom is provided with counterbore, and described stud is located inside counterbore.
Compared with prior art, beneficial point of the present utility model is：
This clamp structure is simple, manufacture and it is easy to loading and unloading, cost is relatively low, and can apply finite element analysis technology, emulation
The stress distribution situation of thin-walled framework under difference positioning and Fixture Layout, rationally compression and fast aligning part, can guarantee that part
Machining accuracy and raising production efficiency.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is sectional view of the present utility model.
Embodiment
Technical scheme is clearly and completely described below in conjunction with accompanying drawing, it is clear that described implementation
Example is part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill

In the description of the invention, it is necessary to explanation, term " " center ", " on ", " under ", "left", "right", " vertical ",
The orientation or position relationship of the instruction such as " level ", " interior ", " outer " be based on orientation shown in the drawings or position relationship, merely to
Be easy to the description present invention and simplify description, rather than instruction or imply signified device or element must have specific orientation,
With specific azimuth configuration and operation, therefore it is not considered as limiting the invention.In addition, term " first ", " second ",
" the 3rd " is only used for describing purpose, and it is not intended that instruction or hint relative importance.
In the description of the invention, it is necessary to illustrate, unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；Can
To be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary, Ke Yishi
The connection of two element internals.For the ordinary skill in the art, with concrete condition above-mentioned term can be understood at this
Concrete meaning in invention.
A kind of milling clamper for being used to reduce thin-wall frame frame clamping deformation as depicted in figs. 1 and 2, including clip base 1, institute
The clip base 1 stated is provided with stud 4, and described stud 4 is located at the center of clip base 1, and stud 4 runs through whole clip base
1, described clip base 1 is provided with alignment pin 2, and alignment pin 2 has two, and two alignment pins 2 are respectively positioned at clip base 1
Both sides, and in alignment pin 2 some insertion clip base 1, the upside of described alignment pin 2 is provided with pressing plate 3, described pressing plate 3
Center is provided with screw, and described stud 4 runs through screw, and the upper end of pressing plate 3 is provided with nut 5, the described clamping platen 3 of nut 5.
Optimize as one kind, the described bottom of clip base 1 is provided with counterbore 7, and described stud 4 is located inside counterbore 7.
In use, it is connected by processing the positioning hole on part 6 with the alignment pin 2 in clip base 1, to processing part 6
High accuracy positioning is realized, the fixture is positioned using holes one side, using alignment pin 2 as positioning datum, then will be processed with pressing plate 3
After part 6 compresses, pressing plate 3 is locked with nut 5, is easy to the rapid accurate center and orientation for determining part, easily facilitates coordinate
Origin is established, calibration time when can greatly reduce clamping, while labor intensity is also greatly lowered.In positioning clamped position
After it is determined that, the stress distribution situation of the thin-walled framework under different clamping force parameters, shadow of the analysis clamping force to part deformation are emulated
Rule is rung, optimization clamps force parameter, compression force parameter quantitative needed for Work-sheet pressing is provided for operative employee, avoids thrust because of people
Depending on.
This clamp structure is simple, manufacture and it is easy to loading and unloading, cost is relatively low, and can apply finite element analysis technology, emulation
The stress distribution situation of thin-walled framework under difference positioning and Fixture Layout, rationally compression and fast aligning part, can guarantee that part
Machining accuracy and raising production efficiency.
