The axial mobile corresponding realization powershift of body.
How to realize that three special exercise patterns of manipulation main shaft 40, the present invention provide following preferred embodiment, i.e. manipulation control
Making sheet 20 is located at upper tank mouth or the case top of cabinet 10, and control crank 30 is in vertical posture.Vertical appearance herein
State includes two layers of meaning, i.e., is upright state at origin parking stall, deviates the oblique of orthostatic position for low-angle when other each stations
Vertical posture.It is arranged so the specific posture of control crank 30, is not only convenient for being manually operated, operator is also convenient for and observes manipulation control
The operation instruction that making sheet 20 provides, and the arrangement of manipulation and control plate 20 changes the side vertical plate arrangement used in the prior art
The traditional design of control panel, operator carry out operation acknowledgement without sidelong glance of bending over.In conjunction with Fig. 8 and relevant view.
In conjunction with Fig. 8, manipulate the cross-drilled hole section 211 that pilot hole 21 includes lateral arrangement, one end of cross-drilled hole section 211 be longitudinally arranged
Vertical hole section connection intersection be origin parking stall.When origin parking stall is exactly that control crank 30 is located at the position, input
The connection of power and all delivering gears disconnects, and sliding box is in stationary state.It should be noted that each in above scheme
The direction that the direction of hole should be fed with the transverse direction of sliding box, long feed distinguishes, that is, manipulates pilot hole 21 on the whole
Intersect for three hole portion communication types and constitutes, wherein the strip-shaped hole in the same direction with lathe spindle is defined transverse direction, it is vertical with lathe spindle
Strip-shaped hole be interpreted as longitudinal direction.
The phenomenon that being interfered in order to avoid the operation of long feed auto-feed and traverse feed auto-feed, or
Person says that the operation of long feed auto-feed and traverse feed auto-feed has to pass through a pause station or stopped to be slow
It crosses, the side of stirring that control crank 30 corresponding to long feed auto-feed and traverse feed auto-feed should be needed to implement
It is distinguished to position,
Concrete scheme is exactly to manipulate the middle part of the vertical hole section in pilot hole 21 to intersect with the connection of cross-drilled hole section 211, is stopped with origin
Parking stall is that origin extends composition traverse feed vertical hole section 212 and long feed vertical hole section 213, traverse feed vertical hole round about
Section 212 is the arranged for interval for closing on formula with 213 liang of parallel and ipsilateral hole walls of hole length direction of long feed vertical hole section.Above scheme
In the so-called arranged for interval for closing on formula be exactly require first control crank 30 carry out long feed feeding with traverse feed feed
Conversion operation when, guarantee that operating efficiency wants high, i.e. the cloth set of traverse feed vertical hole section 212 and long feed vertical hole section 213
Setting should close on preferably, and spaced apart effect is embodied in both traverse feed vertical hole section 212 and long feed vertical hole section 213 simultaneously
On the same line, the relationship that the two has dislocation, the dislocation connectivity part of the two is just exactly origin parking stall at non-place, so conversion
Control crank 30 can occur all using origin parking stall as originating point and regression point to avoid the phenomenon that maloperation in this way, can also be with
It is interpreted as providing safety mutual lock-bit between each feed auto-feed movement of sliding box.
