Connect, coarse positioning pin is embedded with the knife rest, and described coarse positioning pin one end extends to and the tool rest is inserted outside the knife rest
It is interior, inserted with ball stud in the knife rest, and indexable set, institute are nested with the knife rest of the ball stud side on central shaft
State knife rest top end and be fixed with brushgear housing, and brush is installed with the brushgear housing.
Preferably, the central shaft end in the knife rest is installed with sending unit by nut.
Preferably, the brushgear housing is provided with 2, and the brushgear housing is located at the knife rest central shaft both sides respectively, and each
Brush is mounted on the brushgear housing.
Preferably, the motor is DC servo motor.
The utility model proposes a kind of new multi-index tool holder, beneficial effect is：The utility model is compact-sized,
Easy to use, accurately and reliably, steady safety, index time is short, and repetitive positioning accuracy is high for indexing, by dual coarse positioning mechanism,
Make saddle rotation steady, clamp rigidity height, suitable heavy load cutting, there is good economic benefit and social benefit, suitably push away
It is wide to use.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1-2, a kind of new multi-index tool holder, including motor 1 and tool rest 5, the one end of tool rest 5 are connected with motor 1,
Worm shaft 3 is provided with tool rest 5, and the output end of motor 1 is connected by shaft coupling 2 with worm shaft 3, in the tool rest 5 of the top of worm shaft 3
Provided with worm gear 4, and worm gear 4 is connected with worm shaft 3, and the upper end of tool rest 5 is connected by fluted disc 6 with knife rest 7, is embedded in knife rest 7
There is a coarse positioning pin 14, and the one end of coarse positioning pin 14 is extended in the outside of knife rest 7 insertion tool rest 5, inserted with ball stud 8 in knife rest 7,
And indexing set 9 is nested with the knife rest 7 of the side of ball stud 8 on central shaft, the top end of knife rest 7 is fixed with brushgear housing 10, and brush
Brush 13 is installed with seat 10.Central shaft end in knife rest 7 is installed with sending unit 11 by nut 12.Brush
Seat 10 is provided with 2, and brushgear housing 10 is located at the center shaft end both sides of knife rest 7 respectively, and is mounted on brush on each brushgear housing 10
13.Motor 1 is DC servo motor.
Specifically, in use, after numerical control device sends tool changing instruction, motor 1 starts normally, passes through box coupling 2
Rotate worm shaft 3, so as to drive worm gear 4 to rotate.The endoporus of knife rest 7 is threaded, and is screwed with threaded screw rod, worm gear 4 with
Leading screw is overall structure.Worm gear endoporus coordinates with the central shaft type gap of knife rest 7, and in indexable tool changing, central shaft is fixed, snail
Wheel rotates around central shaft.When worm gear 4 starts to rotate, because the end-tooth on tool rest 5 and knife rest 7 is in engagement, and snail
Axial restraint is taken turns, therefore knife rest 7 lifts, after knife rest is lifted to certain distance, the end face body of knife rest tool rest 5 and knife rest 7 disengages, and turns
Position set 9 is coupled with pin with worm gear 4, is together rotated with worm gear 4, and when end-tooth is completely disengaged, indexing set 9 just turns over 160 °,
Ball stud 8 enters in the groove of indexing set 9 under spring force, and the indexing of band movable knife rack 7, knife rest 7 drives brush when rotating
Seat 10 is rotated, and when going to the knife that program is specified, coarse positioning pin 15 enters in the groove of fluted disc 6 under spring force to be carried out
Coarse positioning, while brush 13 contacts conductor and overturns motor 1.Due to the limitation of coarse positioning groove, knife rest 7 can not rotate, make its
The position is vertically fallen, and the end-tooth engagement realization on knife rest 7 and tool rest 5 is accurately positioned, and motor 1 continues to invert, now worm gear 4
Stop operating, the own rotation of worm shaft 3, when both ends of the surface tooth increases to certain clamping force, motor 1 stops operating, by sending unit
11 composition code translators, brush 13 is responsible for signalling, judge when the positioning of knife rest 7 occurred position or it is not in place when, nut can be unclamped
12, mix up the relative position of sending unit 11 and brush 13.
The utility model is compact-sized, easy to use, and accurately and reliably, steady safety, index time is short, resetting for indexing
Precision height, by dual coarse positioning mechanism, makes saddle rotation steady, clamps rigidity height, suitable heavy load cutting, has well
Economic benefit and social benefit, are suitably promoted the use of.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model
Within enclosing.
