A kind of knife machining mechanism of lathe of the present invention, as shown in Figs. 1-2, including spindle carrier 1, main shaft 2, tool striking device 3,
Main shaft 2 and tool striking device 3 are arranged on spindle carrier 1, and tool striking device 3 pushes the capping 31 of forging a knife of main shaft 2, realizes to main shaft
2 forge a knife, and when the capping 21 of forging a knife of main shaft 2 pushes, capping 21 of forging a knife driving ring of forging a knife pushes and then beats the fixture in main shaft 2
Open, and then cutter can take out out of main shaft 2.
Tool striking device 3 includes crank 31, the first actuator 32, cam 33, elastic component 34 and stent 35 of forging a knife, the first actuating
Device 32, which is arranged on, forges a knife on stent 35, and cam 3 is connected with the first actuator 32, and the first actuator 32 can be motor, and first causes
Dynamic device 32 is rotated with moving cam 33, and crank 31 is rotatably arranged on spindle carrier 35 by axis, one end of elastic component 34 with
Stent 35 of forging a knife is fixed, and the other end is fixed with crank 31, and elastic component 34 can be spring, elastic component 34 give all the time crank 31 to
The pulling force of cam 33, makes one end of crank 31 be contacted all the time with cam 33, and the other end is arranged on the top for capping 21 of forging a knife, and passes through
First actuator, 32 driving cam 33 rotates, and then crank 31 is moved between initial position and position of forging a knife, and crank 31 exists
During initial position, there are gap, i.e., one end of the crank 31 in the top of capping 21 of forging a knife between crank 31 and capping 21 of forging a knife
Capping 21 does not contact with forging a knife；When forging a knife position, crank 31 is contacted with reaching concept 21.
Above-described embodiment when in use, when needing replacing cutter, in initial position, due to the effect of elastic component,
One end of crank 31 is close to cam 33, and the other end is in the top for capping 21 of forging a knife, and exists a bit with capping 21 of forging a knife
Spacing, when 32 driving cam 33 of the first actuator rotates, one end pivoting of 33 throw crank 31 of cam, crank 31 it is another
End moves closer to capping 21 of forging a knife, and the capping 21 that continues to forge a knife after contact pushes, and reaches position of forging a knife, and capping 21 of forging a knife drives and beats
Knife ring push, open the fixture in main shaft 2, can by manually taking knife, after the completion of, 32 driving cam 33 of the first actuator is anti-
To rotation, due to the effect of elastic component, crank 31 also and then replys initial position.
In one embodiment, lower knife system 4 is further included, lower knife system 4 includes adjustable plate 41 and knife rest 42, and knife rest 42 includes
Immovable support 421 and swivelling tool-holder 422, swivelling tool-holder 422 are rotatably connected with immovable support 421, and knife rest 42 is rotatable solid
It is scheduled on lathe, and pulley 423 is provided with immovable support 421, adjustable plate 41 is fixed on spindle carrier 1, adjustable plate
41 is stepped, it is preferred that has arc connection between the upper lower terrace surfac of adjustable plate 41, knife rest 42 makes pulley by own wt
423 are close to adjustable plate 41 all the time, are moved up and down by adjustable plate 41, make pulley 423 the higher-order face of adjustable plate 41 with compared with
Low order moves between face, and then controls knife rest remote and close.
As in Figure 2-4, lower knife system 4 is installed on lathe, and lathe includes lathe bed 7, column 5, upper bracket 6, column 5
One end is fixed on lathe bed 7, and the other end is fixed with upper bracket 6, and spindle carrier 1 is slidably disposed in the side of column 5, motor
It is arranged on column 5, screw is vertical to be connected with spindle carrier 1, and motor drives screw and then drive shaft stent 1 moves vertically
Dynamic, when spindle carrier 1 moves up, pulley 423 slides into relatively low terrace from the higher-order face of adjustable plate 41, and knife rest 42 is close to main shaft
2；When spindle carrier 1 moves down, pulley 423 slides into higher-order face from the relatively low terrace of adjustable plate 41, and knife rest 42 is away from main shaft
2。
In above-described embodiment using as described below, when needing replacing cutter, motor drives screw, and then drives main shaft
Stent 1 moves up, and the pulley 423 on the knife rest 42 of side is slided along adjustable plate 41, is moved from higher-order towards relatively low terrace,
Knife rest 42 is gradually close to main shaft 2, and cutter is caught in knife rest 42, and at this time, 32 driving cam 33 of the first actuator rotates, and promotes bent
31 pivoting of handle, the other end move closer to capping 21 of forging a knife, and the capping 21 that continues to forge a knife after contact pushes, and reaches position of forging a knife
Put, capping 21 of forging a knife drives ring pushing of forging a knife, and opens the fixture in main shaft 2, and motor driving screw continues to drive spindle carrier 1
Move up, cutter departs from main shaft 2, rotates swivelling tool-holder 422, it would be desirable to which the cutter of replacement turns to the lower section of main shaft 2, and motor drives
Dynamic screw drives spindle carrier 1 to move down, and after Cutting tool installation manner enters main shaft 2,32 driving cam 33 of the first actuator rotates backward, due to
The effect of elastic component, crank 31 also and then replys initial position, 2 clamp-on tool of main shaft, and then motor driving screw continues to drive
Spindle carrier 1 moves down, and pulley 423 is moved from lower-order towards higher-order face, is gradually distance from main shaft 2, is continued to move down, motor is (not
Show) drive the cutter in main shaft 2 to rotate, the workpiece on lathe bed 7 is processed.
The beneficial effect that the present invention obtains：
The configuration of the present invention is simple, it is easy to operate, capping of forging a knife is pressed by crank, and in initial position with lid of forging a knife
There are gap between face, the bearing that the reaction damage produced due to processing is forged a knife between capping and ring of forging a knife is avoided, is reduced
Service life, in addition, increase knife rest, avoids worker from directly contacting cutter, there are some potential safety problems, makes tool changing more pacify
Entirely.
The foregoing is merely a prefered embodiment of the invention, is not used for limiting the practical range of the present invention；If this is not departed from
The spirit and scope of invention, to technical scheme is modified or replaced equivalently of the present invention, should all cover the protection in the claims in the present invention
Among scope.
