In in use, external impetus can be inputted to engine base 20, such as electric power and motor, engine base 20 drives above-mentioned cutter-exchange mechanism
Transmission shaft 21 in axial direction moves, and then tool change arm 30 is driven to move, referring to FIG. 10, when tool change arm 30 is moved to first
When setting, tool change arm 30 moves close to engine base 20 and its bearing and leaning portion 22, and the mandril 41 of top valve part 40 is pressed against bearing and leaning portion 22, therefore pushes up
Valve part 40 is moved down relative to tool change arm 30, and top valve part 40 is no longer abut against clamps 50, and clamps 50 can be along tool change arm 30
Mobile, when 90 stress of cutter, can elapse clamps 50 and its convex block 51, be detached from button knife portion 32, or move into button knife by outside
Between portion 32 and convex block 51；0 and Figure 11 are please referred to Fig.1, when tool change arm 30 is moved to first position, bearing and leaning portion 22 and upper surface 31
Axial movement space be equal to or slightly less than the axial height of sealing part 60, therefore sealing part 60 is folded in the upper of tool change arm 30
Between surface 31 and the bearing and leaning portion 22 of engine base 20, and surrounds mandril 41 and wear the part being exposed in axial movement space, sealing part
60 can close the gap between mandril 41 and the trepanning 311 of tool change arm 30, when cutter-exchange mechanism is standby by machine for automatic working, can keep away
Without cutting liquid enters in tool change arm 30, to keep top valve part 40 in the smooth degree moved in tool change arm 30.
It please refers to Fig.4 to Fig. 6, engine base 20 can continue to drive transmission shaft 21, be moved to the second position, transmission shaft 21 is in an axial direction
Direction moves down, and the mandril 41 for pushing up valve part 40 is no longer pushed against by bearing and leaning portion 22, and top valve part 40 resets and upwards against clamps
50, prevent clamps 50 from arbitrarily moving, cutter 90 cannot elapse clamps 50, thus cannot be detached from button knife portion 32；At this point,
Since cutter-exchange mechanism is executing tool changing operation, other than machine for automatic working can stop spraying cutting fluid, transmission shaft 21 can also drive
Tool changeover, tool change arm 30 will be rotated by drive, and centrifugation force effect can be relied on to get rid of 31 remaining cutting fluid of upper surface and fallen, made
Cutter-exchange mechanism is obtained when executing tool changing operation, remaining cutting fluid will not be via between mandril 41 and the trepanning 311 of tool change arm 30
Gap enter in tool change arm 30, can maintain top 40 mobile route of valve part headroom.
Using above-mentioned cutter-exchange mechanism, when cutter-exchange mechanism is standby by machine for automatic working, machine for automatic working uses when processing
Cutting fluid can be stopped by sealing part, top valve part will not be entered in the mobile route in tool change arm, top valve part is can avoid and move
Dynamic path is cut liquid filling, and top valve part movement can be maintained smooth, so that it is guaranteed that clamps can be acted according to preassigned pattern, maintains
The task performance of cutter-exchange mechanism.
2 to Figure 15 are please referred to Fig.1, in the utility model second embodiment, element and its connection in cutter-exchange mechanism close
It is similar to the cutter-exchange mechanism of the utility model first embodiment shown in Fig. 4 to Fig. 7, precisely because the hole that is nested with of middle sealing part 60 is blind
Hole, mandril 42 is inserted in the hole that is nested with of sealing part 60, therefore sealing part 60 is sheathed on the top of mandril 42；Please refer to the 14th and figure
15, when tool change arm 30 is moved to first position, sealing part 60 is not only coated on around mandril 42, and coats mandril 42 simultaneously
Top, can play it is similar with aforementioned first embodiment use function.
Summarize described above, the revealed cutter-exchange mechanism of the utility model can be standby by machine for automatic working, when standby
It can effectively prevent cutting fluid to enter in tool change arm, maintain the original task performance of cutter-exchange mechanism, have good using effect, to certainly
Dynamicization mechanical processing, which has, greatly to be benefited.
