As Figure 1-3, a kind of fast advance and retreat cutter mechanism, including slidable feeding are provided in the utility model embodiment
Vertical shaft and processed cutter are installed on planker 2, buffer unit and pneumatic actuator system, feeding planker 2；It is understood that
The mechanism is installed in operation on lathe bed 1, and feeding planker 2 is slidably connected on lathe bed 1 by line slideway auxiliary, that is, is entered
It can be moved left and right to planker 2 with respect to lathe bed 1；Wherein, buffer unit includes the first buffer and the second buffer；Feed planker
2 left end connection pneumatic actuator system, by pneumatic actuator system drive feeding planker 2 on lathe bed 1 forward feeding or backward
Move back, so as to realize the feed process and withdrawing process of cutter；Pneumatic actuator system includes the cylinder 4 being fixed on lathe bed 1 and control
The air pressure transmission control system 5 that cylinder 4 processed is acted, cylinder 4 includes the piston rod 402 of cylinder body 401 and Telescopic movable, piston rod
402 left end is in cylinder body 401, and the right-hand member of piston rod 402 can be protruding, and the head (right-hand member) of cylinder body 401 is provided with first
Buffer 6, using variable buffering, can buffer feeding planker 2 and move backward when realizing rapid return, feeding planker 2 itself
Impact of the kinetic energy to lathe bed 1, prevent lathe bed from vibrating；The right-hand member connection feeding planker 2 of piston rod 402, in Pneumatic Transmission control
In the presence of system 5, piston rod 402 travels forward in cylinder body 401 or moved backward, so as to drive the feeding of feeding planker 2
Or retreat, air pressure transmission control system 5 includes air compressor machine 501, pressure-reducing valve 502 and the two-position five-way valve 503 being sequentially connected, two
Position five-way valve 503 a mouth by the first one-way throttle valve 504 connect cylinder body 401 one end, two-position five-way valve 503 it is another
