Cylinder, front support seat, movable V-shape cushion block and rear support seat；Also there is column at left and right sides of the front support seat, wherein
There is the holding device for laterally compressing forging part on the column of side；Also there is pressing plate and bolt on base, the bolt passes through
The elongated hole of pressing plate, apply downward thrust by nut；One end of rotating handle is rotatably connected with base, and the other end has laterally
Support bar, to forging part rear portion provide cross-brace.
The front support seat is horizontal cuboid, and the rear support seat is cylinder, and the upper surface of two fulcrum bearings exists
Identical plane, support is provided to the front and back end of forging part.
The movable V-shape cushion block can move forward and backward on the base, to providing support in the middle part of forging part.
The positioning cylinder is combined with the U-shaped support arm of forging part so as to spacing.
The pressing plate and bolt are two groups, respectively positioned at the left and right sides of base, and front and rear are staggered.
The column is in cuboid.The support bar is to be connected to form with screw rod by a circular top cap.Plate, by circular top
Cap removes machining area.
Beneficial effect：The adjustable clamp processed by the undercarriage forging part, can reach quick-clamping, and clamping is stable
Property effect, because clamping can stably improve process velocity, so as to improve production efficiency, and changes last compacted position and keeps away
Exempt from because of overproof problem caused by deformation, friendship inspection qualification rate is reached absolutely.

Embodiment
A kind of adjustable clamp for the processing of undercarriage forging part, there is setting circle successively from the front to the back on base 1
Post 4, front support seat 2, movable V-shape cushion block 9 and rear support seat 3；Also there is column 8 in the left and right sides of front support seat 2,
There is the holding device 5 for laterally compressing forging part wherein on the column 8 of side；Also there is pressing plate 7 and bolt 10 on base 1,
The bolt 10 passes through the elongated hole of pressing plate 7, and applies downward thrust by nut；One end of rotating handle 6 connects with the rotation of base 1
Connect, the other end has horizontal support bar 11, and cross-brace is provided to forging part rear portion.
The front support seat 2 is horizontal cuboid, and the rear support seat 3 is cylindrical, the upper surface of two fulcrum bearings
In identical plane, support is provided to the front and back end of forging part.
The movable V-shape cushion block 9 can move forward and backward on the base 1, to providing support in the middle part of forging part.
The positioning cylinder 4 is combined with the U-shaped support arm of forging part so as to spacing.
The pressing plate 7 and bolt 10 are two groups, respectively positioned at the left and right sides of base 1, and front and rear are staggered.
The column 8 is in cuboid.
The support bar 11 is to be connected to form with screw rod by a circular top cap.Plate, circular top cap is removed into machining area.
This size of clamp base 1 is about long 420mm, wide 220mm, high 40mm.Design elements bottom surface datum plane, wherein
Two datum marks be on cuboid, another datum mark on the cylinder, two datum marks of cuboid and one benchmark of cylinder
Point is highly consistent, bottom surface positioning reference plane of this 3 points planes formed as part, but this plane is higher than basic plane 20mm,
Prevent part from interfering in process.
Design elements side Y-axis positioning reference plane, column 8 are in cuboid, and size is long 50mm, wide 40mm, high 55mm, position
Put in the upside of base 1 and need to guarantee to undertake stress intensity, prevent with cuboid datum plane symmetrical centre, column 8
Part processing is subjected to displacement, but is also noted that and excessive can not be prevented part from interfering in process.In the vertical of side
A M12 screwed hole is processed on post 8, is passing through the six long 90mm of side's screw rod in M12 above, six side's screw rod other ends accompany one inside
Circular top cap.It can reach flexible and hold out against effect.
Design elements X-axis positioning cylinder 4, diameter 25mm, height 60mm, part processing is prevented to be subjected to displacement, this setting circle
Post 4 needs to guarantee to undertake stress intensity.
