Description
Technical field
The utility model relates to technical fields of mechanical processing, specifically a kind of that thin-walled parts are processed in vertical machining centre
Used fixture.
Background technique
With the development of engine technology, the requirement to part is that the lighter weight the better, but to the air-tightness requirement of part
It is higher and higher, so the thin-walled parts on engine are more and more.
Thin-wall part work in-process is easily deformed, lead to the geometric tolerances such as flatness, the depth of parallelism, position degree it is difficult to ensure that.
Especially be just to easily lead to part air-tightness if flatness is overproof and do not reach requirement, so how work in-process is reduced
Deformation is just critically important, and the reliability for improving fixture is exactly a technology of wherein most critical.
Utility model content
The utility model provides a kind of thin-walled parts milling face boring grab, effectively prevents machining deformation, adjusts rationally
After whole cutting data, flatness can reach within 0.1.
The utility model technical solution used for the above purpose is：Thin-walled parts mill face boring grab, pedestal
At least two positioning pins of upper installation and at least three contour positioning supports, three contour positioning supports are not in straight line
On, long pressing plate one end is positioned by platen support, adjusts the vertical height of long pressing plate；Lead between the long pressing plate other end and lower section pressing plate
Crossing rotation axis connection can adjust pressing plate horizontal direction position, connect hydraulic cylinder below the long pressing plate, hydraulic cylinder is fixed on
On pedestal.
Further, 6-8 auxiliary floating support is installed on the pedestal.
Further, setting hydraulic circuit gives hydraulic cylinder fuel feeding in the bottom plate.
The beneficial effects of the utility model are：Clamp structure design rationally, effectively prevents thin-walled parts process
In easily-deformable problem.
Detailed description of the invention
Fig. 1 is thin-walled parts structural schematic diagram.
Fig. 2 is clamp for thin-walled part total figure.
Fig. 3 is the cross-sectional view one for removing parts thereof fixture.
Fig. 4 is the cross-sectional view two for removing parts thereof fixture.
Specific embodiment
Explanation is further explained to the utility model combined with specific embodiments below.
As shown in Figs 1-4, thin-walled parts mill face boring grab, install two floating positioning pins 2 on pedestal 1 and three contour
Positioning support 3, not point-blank, this three-point shape is at a positioning surface for three contour positioning supports 3.Long pressing plate 4
One end is positioned by platen support 5, adjusts the vertical height of long pressing plate 4；Guarantee 3 points of casting while compressing, long pressing plate 4 is another
It can make pressing plate angle in the horizontal direction in a certain range by the connection of two vertical axis of rotation 6 between one end and lower section pressing plate 10
It automatically adjusts, hydraulic cylinder 7 is connected below the long pressing plate 4, hydraulic cylinder 7 is fixed on pedestal 1.In order to increase rigidity, subtract
Vibration when processing less installs 6 auxiliary floating supports 8 in addition to two floating positioning pins again on pedestal.It is set in the bottom plate
Hydraulic circuit 9 is set to hydraulic cylinder fuel feeding.
In use, being that compression cylinder is started to work first, by the platen support on pedestal, by power after logical oil
It is conducted to long pressing plate, pressure is transmitted by long pressing plate → rotation axis → pressing plate afterwards, part is tightly pressed against three stationary anchor points
On（Pass through contour positioning support）, ensure that the reliable of positioning；After workpiece compresses, pass through the work of the sequence valve in hydraulic circuit
With 6 auxiliary floating supports support on workpiece lower end surface simultaneously, ensure that the positional accuracy of workpiece in this way, and increase
The rigidity of part, the deflection of part when greatly reducing processing.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is practical according to this in the technical scope that the utility model discloses
Novel technical solution and its design is subject to equivalent substitution or change, should be covered within the scope of the utility model.
