Processing, including some dynamic tool aprons 22 located at described power knife rest, motorcutters 23 are installed on some described dynamic tool aprons 22
Interior, also include servomotor 1, power transmission shaft 4, power transmission shaft 18, synchronous pulley 6, synchronous pulley 13, ball bearing 3, ball axle
Hold 21 and Timing Belt 5, described servomotor 1 passes through yielding coupling 2 and carries out elastic connection, described biography with described power transmission shaft 4
Moving axis 4 other end is provided with described synchronous pulley 6, and described power transmission shaft 4 is supported on knife rest casing 7 by described ball bearing 3
On, described power transmission shaft 18 bearing is arranged on described knife rest casing 7, and described power transmission shaft 18 passes through two described ball bearings
21 are supported in power transmission shaft 18 bearing, and described synchronous pulley 13, described synchronous pulley are installed in described power transmission shaft 18 one end
Described Timing Belt 5 is installed between 6 and described synchronous pulley 13.
Described power transmission shaft 18 one end is machined with " one " font keyway 18.1, and described keyway 18.1 both sides are provided with chamfering
18.2, dynamic tool apron 22 input shaft end is machined with " one " font key 22.1, and described keyway 18.1 is joined with the activity of described key 22.1
Close and connect.
There is the gap f of axial direction in connected state in described keyway 18.1 and described key 22.1.
Guiding disc carrier 10 is arranged on knife rest casing 7, and positioning disk 9 is arranged on guiding disc carrier 10, and positioning disk 9 sets
There is spigot surface 9.1, described spigot surface 9.1 is fitted with the side of described key 22.1.
The end of described power transmission shaft 18 is provided with detection block 12, and described detection block 12 is provided with two symmetrical detect tanks
12.1, the central plane of described detect tank 12.1 is mutually perpendicular to the central plane of described keyway 18.1, described detection switch 11

Revolution, on " one " font key 22.1 and power transmission shaft 18 of the dynamic tool apron 22 input shaft end being now in operating position
" one " font keyway 18.1 is in bonding state and there is the gap f of axial direction between the two, because cutterhead 8 is rotating tool changing
When axial movement value be less than gap f, be thus in " one " font key of the dynamic tool apron 22 input shaft end of operating position
22.1 complete the disengaging with " one " the font keyway 18.1 on power transmission shaft 18 with the revolution motion of dynamic tool apron 22.
On the other hand, when cutterhead 8 proceed by rotation tool changing when, due to the spigot surface 9.1 on positioning disk 9 be in non-work
The side making " one " font key 22.1 of dynamic tool apron 22 input shaft end of position fits, and is thus in off-position
Slide it is ensured that locating on the spigot surface 9.1 of positioning disk 9 in the side of " one " font key 22.1 of dynamic tool apron 22 input shaft end
Dynamic tool apron 22 input shaft in off-position will not rotate skew, because the axial direction when rotating tool changing for the cutterhead 8 is altered
Momentum is less than " one " font key 22.1 of " one " the font keyway 18.1 on power transmission shaft 18 and dynamic tool apron 22 input shaft end
With reference to when there is the gap f of axial direction between the two, be thus in the dynamic tool apron 22 input shaft end of off-position
" one " font key 22.1 complete and " one " the font keyway 18.1 on power transmission shaft 18 with the revolution motion of dynamic tool apron 22
Combination, so, just complete " one " the font key of the dynamic tool apron 22 input shaft end being in operating position, off-position
22.1 with power transmission shaft 18 on " one " font keyway 18.1 depart from combine process, the power knife of operating position originally
Seat 22 becomes the dynamic tool apron 22 of off-position, and the dynamic tool apron 22 of off-position originally becomes the power of operating position
Tool rest 22, is also achieved that the tool changing of power knife rest.
Compared with correlation technique, the utility model provide the power knife rest for driving and changing motorcutters have as
Lower beneficial effect:
(1) power source of power knife rest to dynamic tool apron power transmission to be realized using synchronous band structure, effectively drop
Noise during low motorcutters work.
(2) it is ensured that cutterhead is turning by way of match grinding being carried out to adjusting pad when the structure using positioning disk and assembling
Move " one " the font keyway on " one " font key of dynamic tool apron input shaft end during knife and power transmission shaft smoothly depart from
In conjunction with it is achieved that the tool changing of power knife rest, compared with drive mechanism, structure is simple, and failure rate of machinery is low.
(3) this structure does not need the support of system liquid pressure, is not therefore affected by factors such as system hydraulic pressure, and reliability is high.
