The middle part of push rod 14 offers guide groove, and the glide direction of the bearing of trend of guide groove along push rod 14 is set.The cunning
The center of dynamic groove one end is higher than the center of its other end in the height direction, and a part for guide finger 10 passes through guide groove and energy
It is enough to be moved in guide groove.In the present embodiment, due to there is provided two sliding eyes and supporting two push rods 14, then guide finger 10
Both ends correspond to respectively to be slided in the guide groove on a push rod 14 with realizing to balance.
The tool rest of above-mentioned automatically replaceable cutter includes two states, respectively lock-out state and released state.Locking
Under state, the guide finger 10 being connected with drag link sleeve 3 is located in guide groove relatively low one end in position in the height direction, now draws
Bar 8 and pulling claw 7 are entirely located in the through hole of drag link sleeve 3, and pulling claw 7 tightens.When to the tail end of push rod 14, i.e. a left side in accompanying drawing 2,3
Side promote push rod 14 when, spring 18 compresses, guide finger 10 in guide groove gradually by the relatively low one end in position be moved to position compared with
High one end.As the position of guide finger 10 in the height direction changes, it also drives pull bar 8 and pulling claw 7 to move, pulling claw 7
Top is gradually stretched out by the upper end of drag link sleeve 3.The position in the height direction that guide groove is moved to when guide finger 10 is higher
During one end, pull bar 8 and pulling claw 7 also reach the extreme position moved up, and pulling claw 7 unclamps, and the tool rest of automatically replaceable cutter is in solution
Lock status.Now, the lower constraint of pull bar 8 and pulling claw 7 is in the through hole of drag link sleeve 3, so as to which pulling claw 7 be opened, you can to enter
Row tool changing operation.It can be used special purpose interface to be close to push rod cup 16 during automatic tool changer and supplied gas to promote the motion of push rod 14 to reach Song Daohe
Purpose, and cooperative mechanical hand carries out tool changing.And it is manually operated, can make special tooling manually promotes push rod 14 to move, and reaches pine
The purpose for opening pulling claw 7 carries out tool changing operation, and the elastic force of spring 18 is simple and easy completely within the scope of manpower can compress.
After tool changing, push rod 14 drives pull bar 8 and the return of pulling claw 7, returns to lock-out state.
In addition, the end face of push rod 14 can process the inner chamber that passage carrys out UNICOM's base 5.In the case of automatic tool changer,
It can outwards be blown around pulling claw 7 when cutter and pulling claw 7 separate, ensure that the bellmouth of broach shell 1 is clean.The side of base 5
Cutting fluid entrance can also be processed, and is connected to the end face of broach shell 1, the end face of broach shell 1 sets telescopic interface for being connected with
The cutter of nozzle of cutting fluid uses.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
Personage can understand content of the present utility model and implement according to this, the scope of protection of the utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover the scope of protection of the utility model it
It is interior.
