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.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment：
As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of Lathe chuck jaw structure, including chuck body 1 and card
Disk retaining mechanism 2, the top of chuck body 1 are provided with three guide grooves 3, claw 4 are respectively arranged with the guide groove 3 described in three,
Claw 4 described in three is distributed in hexagonal angle, and the locking chuck mechanism 2 includes bevel gear wheel 5 and bevel pinion 6, described small
Bevel gear 6 drives bevel gear wheel 5, and the back side of the bevel gear wheel 5 is provided with archimedean spiral groove 7, Archimedes's spiral shell
Spin slot 7 meshes together with the claw 4 described in three, and taper hole 8, the taper hole 8 and lathe spindle are provided with the chuck body 1
The male cone (strobilus masculinus) of 9 front ends coordinates, and the chuck body 1 on lathe spindle 9, is provided with by nut check on the bevel pinion 6
Four square holes 10, the lower section of the chuck body 1 are provided with rotary body 11, and the rotary body 11 passes through the connection card disk body 1 of rotating dog 12.
When rotating bevel pinion 6 by four square holes 10 with spanner, bevel pinion 6 drives big vertebra gear 5 to rotate, big vertebra tooth
The archimedean spiral groove 7 for taking turns the back side drives three claws 4 close or exit to the center of chuck body 1 simultaneously, to clamp difference
