Cylinder (8) lower section is provided with keel (14)；
Be installed with on the rear wall of described right riser (5) be perpendicular to rear wall right suit cylinder (6) and
Back fork prong width coupling also can stretch into the right locating piece (7) in back fork prong, at the bottom of frock
Vertical cylinder (8) in being arranged above of plate (1), when the circle hole sleeve of back fork is right suit cylinder (6)
On, when the rightest locating piece (7) stretches in the prong of back fork, in the push rod of vertical cylinder (8)
Just being bearing in the lower surface of back fork after protruding upward, the push rod of right vertically cylinder (10) is upwards stretched
Just be bearing in the waist of back fork after going out, described in the vertically push rod of cylinder (8), right suit cylinder
(6), the right vertically push rod of cylinder (10), right locating piece (7) from left to right set gradually；
Be installed with on the rear wall of described left riser (4) be perpendicular to rear wall left suit cylinder (11),
The left locating piece (2) that mates with back fork prong width and can stretch in back fork prong, for
Hold the left rest pad (3) of back fork upper surface, after back fork rotates 180 ° counterclockwise, and will fall
The circle hole sleeve of gear shift fork is on left suit cylinder (11), and the most left locating piece (2) stretches into back fork
When prong is interior, left rest pad (3) is bearing in below the upper surface of back fork, left vertically cylinder (9)
Push rod protrude upward after be just bearing in the waist of back fork, and left locating piece (2), left vertically gas
The push rod of cylinder (9), left suit cylinder (11), left rest pad (3) from left to right set gradually；
The facing cutter of described vertical knee-type milling machine (13) is positioned between left riser (4) and right riser (5), left
The axis of suit cylinder (11) is equal to the axis of right suit cylinder (6) to milling to the distance of facing cutter axis
The distance of cutter axis.
Using method: first place workpiece to be processed, by the circle hole sleeve of one of them back fork at right set
On dress cylinder, and make right locating piece snap in the prong of back fork, by another back fork (simultaneously
The back fork of the good upper surface of milling) counterclockwise rotate 180 ° after, then by the circle hole sleeve of this back fork on a left side
On suit cylinder, and make left locating piece snap in the prong of this back fork, left rest pad is bearing in and reverses gear
(owing to the back fork in left side has processed upper surface, therefore can directly make below the upper surface of shift fork
Use left rest pad, and the lower surface of right side back fork is matsurface, in addition it is also necessary to vertical gas in increasing by one
Cylinder uses as rest pad)；Afterwards, vertical cylinder, left vertically cylinder and the vertical cylinder in the right side in restarting,
The push rod making vertically cylinder is just bearing in the lower surface of right side back fork after protruding upward, right vertical
The push rod of cylinder is just bearing in the waist of right side back fork, the push rod of left vertically cylinder after protruding upward
Just being bearing in the waist of left side back fork after protruding upward, now Set and Positioning completes；Due to two
Back fork opposition is arranged, and the facing cutter of vertical knee-type milling machine is placed exactly between two back forks, under facing cutter
The right side upper plane of back fork, the lower plane of left side back fork is processed at one time after row.Process
Cheng Hou, after machining, facing cutter and each vertical ejecting rod of cylinder return, the back fork in left side is taken off,
After the back fork on right side rotates 180 ° counterclockwise, the clamping position putting into left side proceeds lower plane
Process, then the clamping position that the workpiece that new is put into right side carries out the processing of upper plane.
Preferred as such scheme, described locating piece right, left (7,2) is by stretching into back fork fork
Position portion in Kou, the mounting portion being positioned at outside back fork prong one composition, position portion with fall
The prong matched in clearance of gear shift fork, the width of mounting portion is more than position portion, described right locating piece (7)
Mounting portion relative to its position portion downward bending.Set up installation position for each self-corresponding riser
Fixing, the prong matched in clearance of position portion and back fork to facilitate workpiece loading and unloading, the peace of right locating piece
Dress part its position portion downward bending relatively takes up room to reduce, thus reduces the height of right riser.
Further, the vertical cylinder in a described left side (9), the push rod termination of right vertically cylinder (10) are curved surface,
And it is supported by the SURFACES MATCHING at position with selector fork.Employing curved surface coordinates, and to increase contact area, carries
High supporting dynamics.
Beneficial effects of the present invention: novel, designs ingenious, by clamp system, clamping workpiece is fixed
Position, then with vertical knee-type milling machine, the lower planes of shift fork is finished, can once complete the upper of a workpiece
The lower plane processing of plane and another workpiece, convenient mounting and clamping is quick, substantially increases production efficiency and processing
Precision.

Preferably, right locating piece 7, left locating piece 2 by the position portion stretched in back fork prong,
The mounting portion one composition being positioned at outside back fork prong, position portion and the prong gap of back fork
Coordinating, the width of mounting portion is more than position portion, and the mounting portion of right locating piece 7 is relative to its location division
Divide downward bending.Meanwhile, left suit cylinder 11, the diameter of right suit cylinder 6 and the circular hole of back fork
Diameter matches, both matched in clearance, facilitate mounting or dismounting.
It addition, the push rod termination of left vertically cylinder 9, right vertically cylinder 10 is curved surface, and dial with gearshift
Fork is supported by the SURFACES MATCHING at position.
Before processing, first place back fork 12 to be processed, by the circle of one of them back fork 12
Borehole jack is on right suit cylinder 6, and makes right locating piece 7 snap in the prong of back fork 12, will simultaneously
After another back fork 12 (back fork of the good upper surface of milling) rotates 180 ° counterclockwise, then should
The circle hole sleeve of back fork 12 is on left suit cylinder 11, and makes left locating piece 2 snap in this back fork
The prong of 12 is interior, left rest pad 3 is bearing in below the upper surface of this back fork 12 (due to falling of left side
Gear shift fork has processed upper surface, and left rest pad therefore be can be used directly, and under the back fork of right side
End face is matsurface, in addition it is also necessary in increasing by one, vertical cylinder uses as rest pad)；Afterwards, restart
In vertically cylinder 8, left vertically cylinder 9 and the vertical cylinder in the right side 10, in making, the push rod of vertical cylinder 8 is upwards
Just being bearing in the lower surface of right side back fork 12 after stretching out, the push rod of right vertically cylinder 10 is upwards stretched
Just be bearing in the waist of right side back fork 12 after going out, the push rod of left vertically cylinder 9 protrude upward after just
Being bearing in well the waist of left side back fork 12, now Set and Positioning completes；Due to two back forks 12
Opposition is arranged, and the facing cutter of vertical knee-type milling machine 13 is placed exactly between two back forks 12, vertical knee-type milling machine 13
Facing cutter descending, facing cutter process at one time the right side upper plane of back fork 12, left side and reverse gear
The lower plane of shift fork 12.After machining, in vertically cylinder 8, left vertically cylinder 9 and the vertical cylinder in the right side
The push rod of 10 is retracted, and the back fork 12 in left side is taken off by the facing cutter return of vertical knee-type milling machine 13, right
After the back fork 12 of side rotates 180 ° counterclockwise, the clamping position putting into left side proceeds lower plane
Processing, then the clamping position that the workpiece that is new is put into right side carries out the processing of upper plane.
