State the described fixed part on fuselage 1, described vertical arm 41 is lived with described one end of described pull bar 5 with the connecting portion of described transverse arm 42
It is dynamically connected.
By the cooperation each other of vertical arm 41 and transverse arm 42, the rotation of described cam 2 can be effectively transferred to draw
Bar 5 is it is ensured that being synchronized with the movement between cam 2 and pull bar 5.
Meanwhile, the described free end conflicted all the time with described cam 2 of described vertical arm 41 is provided with roller 7, described roller 7
It is in rolling contact with the outer rim of described cam 2.
By roller 7, roller 7, in rotation process, can drive roller 7 to rotate, and effectively reduces cam 2 and drive link 4
Frictional force in contact process, is conducive to the stability of transmission between cam 2 and drive link 4.
In the present embodiment, described ejection assembly includes：Lower ejection axle 8；Rotation section, can be reciprocal around described lower ejection axle 8
Rotate, one end is connected with the described other end of described pull bar 5；Push rod 9, can be reciprocating another located at described rotation section
The top of one end, for ejecting workpiece.
Described rotation section includes：Draft link 10, one end is connected with the other end of described pull bar 5, and can draw described
Under the drive of bar 5, described lower ejection axle 8 is driven to rotate；Fork trailing arm 11, is arranged side by side with described draft link 10, and with described
Lower ejection axle 8 synchronous axial system；Hydraulic pressure fork 12, be set in described lower ejection axle 8 on, the top of described hydraulic pressure fork 12 with described
Push rod 9 contacts, and described hydraulic pressure fork 12 can turn around described lower ejection axle 8 forward direction under the drive of described fork trailing arm 11
Dynamic, drive described push rod 9 to move upwards.
Meanwhile, using bonded between described fork trailing arm 11 and described lower ejection axle 8.
Specific ejection action is as described below：Described cam 2 rotates, and extrudes drive link 4 when cam 2 rotates, and drive link 4 carries
Dynamic pull bar 5 moves down, and pull bar 5 drives draft link 10 to rotate clockwise, by being bonded between draft link 10 and lower ejection axle 8
Connect it is ensured that being synchronized with the movement therebetween, bonded between axle 8 and fork trailing arm 11 with ejecting at present, fork trailing arm 11 can exist
Rotate under the drive of lower ejection axle 8, and by hydraulic pressure fork 12 jack-up, then hydraulic pressure fork 12 is by push rod 9 jack-up, hydraulic pressure fork 12
With workpiece phase separation, thus workpiece is ejected, complete ejection action.
In the present embodiment, described resetting means includes：Reset cylinder 13, is fixedly installed on described fuselage 1, has reciprocal
The piston of motion；Reset fork 14, is driven by described piston, is arranged side by side with described hydraulic pressure fork 12, described reset fork 14
