Time jacking block 10 back to maximum going-back position.
In order to realize the guiding of slide mass 7, there is bottom described slide mass 7 chute 7-2, described support seat
Being fixed with guide blot 11 on 1-1, described guide blot 11 slides in chute 7-2.
In order to increase the rigidity of car die clamper, the middle part of described support seat 1-1 is provided with for withstanding connecting rod 100
The protruding 1-1-1 at middle part.If supporting milling in the middle part of seat 1-1 to put down, support in the middle part of seat 1-1 the thinnest,
The main body curves of car die clamper can be caused, may fracture after working long hours.
Operation principle of the present utility model is as follows:
The location of big end 101 is to be coordinated with locating piece 5 by the interior circular hole of major part 101, i.e. locating piece 5
It is positioned at the circular hole of major part 101.Then by steady pin 2 fixation clip 3, pressing plate 3 withstands big end
The upper end of 101, so that big end 101 is gripped by locating piece 5 and pressing plate 3.Can be by changing
The pressing plate 3 of different-thickness, to adapt to the big end 101 of different-thickness.The extension of pressing plate 3 (i.e. with
The part of big end 101 contact) it is wedge, and pressing plate 3 is fixing.
When unclamping, connecting rod 100 can vertically put in, and will not encounter the extension of pressing plate 3, conveniently put
Put connecting rod 100.After connecting rod 100 is put on support seat 1-1, the cylinder intake after top 16, top 16 past
Front motion, promotes jacking block 10 forward, and jacking block 10 contacts bumper bar 8, thus promotes bumper bar 8 forward, stretches
Go out slide mass 7；Continuing forward, when bumper bar 8 afterbody flushes with slide mass 7, jacking block 10 just pushes cunning
Kinetoplast 7 is the most forward, then just promote connecting rod 100 to travel forward, because having locating piece 5 in location, institute
Will not swing with connecting rod 100, until big end 101 both sides (connecting rod shoulder) bumps against pressing plate 3 and stretch
The wedge part gone out, now connecting rod 101 is clamped, and can process.
During clamping, big end 101 both sides (connecting rod shoulder) is pressed in pressing plate 3 times, small end of connecting rod 102
(connecting rod afterbody), bumper bar 8 times, is fixed up and down.Front and back by cylinder-pressing, left and right is controlled by locating piece 5
System.Locating piece 5 when connecting rod 100 puts at maximum gauge, and without impinging on the inwall of connecting rod 100,
During clamping, connecting rod 100 moves forward, and the inwall of connecting rod 100 gradually encountered by locating piece 5, thus positions.
When unclamping, cylinder is exitted, and top 16 do not stress, under the spring effect of spring catch 12, and jacking block 10
Moving, bumper bar 8 is the most simultaneously backward, after reset screw 13 is encountered at jacking block 10 rear portion, by multiple
Position screw 13 drives slide mass 7 backward, thus pulls connecting rod 100 backward, departs from pressing plate 3, to initial bit
Put, take out connecting rod 100.Retreat how many distances, going-back position expansion screw 14 determine.
Major part fixed part side coordinates scroll chuck, and scroll chuck rotates and drives car die clamper of the present utility model
Rotating, lathe tool is placed in the side of big end 101, while the rotation of car die clamper, lathe tool is to major part 101
Side carries out car mould, and so, major part 101 side can go out circular arc end face by car mould.
Jacking block 10 is withstood, then jacking block 10 and top 16 point cantact of Pneumatic tail by a Pneumatic tail top 16, three
While dog chuck band motor-car die clamper rotates, Pneumatic tail top 16 does not turns, and jacking block 10 rotates.
Top 16 rear portions of Pneumatic tail pass through air cylinder driven, cylinder make Pneumatic tail top 16 can elastic also
Steady statue can be kept when car die clamper rotates.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant
Staff can carry out various change completely in the range of without departing from this utility model technological thought
And amendment.The content that the technical scope of this utility model is not limited in description, it is necessary to root
Its technical scope is determined according to right.
