Tool belongs to a type in jig, is usually made of the part such as positioning device, clamping device, clamp body, connecting element,
It needs to be mounted on milling machine table, makees feed motion with platen.When fraise jig Milling Process, cutting force compared with
Greatly, vibration is larger, therefore the clamping force requirement of fraise jig is larger, and fixture rigidity, intensity requirement are relatively high.How basis waits for
The shape and processing request for processing part design a kind of accurate positioning, reliable clamping, fraise jig convenient for mounting and clamping, become
The object that the present invention studies.
Invention content：
The purpose of this utility model, which is that design is a kind of, to be fixed on the workbench of milling machine, and uses pneumatic pinch mode,
Make parts to be processed that the fraise jig of simultaneously reliable grip be accurately positioned.
What the technical solution of the utility model was realized in：A kind of fraise jig using pneumatic pinch, including fixture
Body, locating piece, positioning pin, left and right clamp arm, tension spring and double end cylinder, left and right clamp arm can be shipped and resell on another market around rotation of shipping and reselling on another market with locking
Double nut fastens；The lower end that the mandril at double end cylinder both ends synchronizes outer top left and right clamp arm is allowed to rotate, to keep the upper end same
Step compresses parts to be processed；It is characterized in that：It further include the cylinder for fixing double end cylinder with screw locking on clamp body
Left and right fastening plates, and for fastening the locking double nut shipped and resell on another market.
The locating piece is positioned and secured at by two positioning pins on clamp body, and left and right two is partly machined on locating piece
Section circular arc, the radian of two sections of circular arcs are consistent with the radian of lower arc surface of parts to be processed.
The parts to be processed is positioned on the arc surface of locating piece, and the right side comes on the right rib of locating piece.
It the both ends of the tension spring, can when double end cylinder loses pressure rotating around being connected in the circular hole of left and right clamp arm lower end
It shrinks and left and right clamp arm is pulled to be allowed to around rotation of shipping and reselling on another market, to unclamp parts to be processed.
Respectively there are one semicircle elongated slots on clamp body bottom both sides, for entire fixture to be fixed on milling machine table.
The utility model, as power, has the function of floating clamping mechanism using double end cylinder, even if parts to be processed clamps
Position is less regular black skin, and two clamp arms can also synchronize compressing component, this fixture has an accurate positioning, reliable clamping,
Feature convenient for mounting and clamping.
Description of the drawings：
The utility model is described further with reference to specific legend：

Specific implementation mode：
Referring to Fig.1, the upper plane 801 of parts to be processed 8 is to need the plane of Milling Process, and lower part, which has, can be used under positioning
The upper arc surface 803 of arc surface 802, upper part is then black skin, can be used as and clamps position.
With reference to Fig. 2 and Fig. 3, fraise jig, including the left fastening plates 3 of clamp body 1, tension spring 2, cylinder, double end cylinder 4, Zuo Jia
Tight arm 5,6, locating piece 7 of shipping and reselling on another market, right clamp arm 9, positioning pin 10, the right fastening plates 11 of cylinder and locking double nut 12；Double end cylinder 4
With screw locking in the left fastening plates 3 of cylinder and the right fastening plates of cylinder 11, the left and right fastening plates of cylinder then equally lock in fixture
On body 1；Locating piece is positioned and secured at by two positioning pins 10 on clamp body 1, and parts to be processed 8 is positioned over locating piece 7
On arc surface 702, and the right side comes on the right rib 701 of locating piece 7, and left and right clamp arm can be around 6 rotations of shipping and reselling on another market, 6 use lockings of shipping and reselling on another market
Double nut 12 fastens, and the both ends of tension spring 6 are rotating around being connected in the circular hole of left and right clamp arm lower end；The middle chamber of double end cylinder 4
When air inlet, the mandril 401 at both ends synchronizes the outer lower end for pushing up left and right clamp arm and is allowed to rotate, and passes through leverage, two clamp arms
