Abstract
The utility model discloses a composite jaw of a three-jaw chuck, comprising chuck jaws. The utility model is characterized in that a head of a chuck jaw is a detachable cylinder, one side of the cylinder is provided with a groove axially, and a positioning key is axially arranged on one side wall of the groove; the side face of the cylinder is provided with a through hole of a fastening bolt which is vertical to the side wall of the groove; the cylinder can be a cylindrical body or can be a prism body, and one lateral face of the chuck jaw is provided with a positioning keyway. The utility model is suitable for various lathes, various parts can be conveniently turned by the utility model, and the work efficiency and the turning quality of the parts can be improved.
Description
The utility model is relevant with the scroll chuck of lathe, is the multiple pawl of the scroll chuck used of lathe scroll chuck specifically.
During other part of the car system cake class of traditional scroll chuck, two weak points are arranged: the one, be difficult for finding accurately by other part retaining part of car system; The 2nd, car system in addition part to be held area little.Thereby easily cause by car system in addition part clamp not strongly, concentricity is poor, makes by the part parallelism of two planes in addition of car system to guarantee.In order to improve the processed quality of part in addition, scroll chuck leading edge car is become step, so just destroyed the original performance of three-jaw, though improved the car system cake class quality of part in addition, process other pieces after giving and bring inconvenience.The soft pawl of traditional scroll chuck is to freeze with former chuck jaw, when manufacturing, whole chuck jaw be heated together, causes the claw distortion easily, influences the quality of fit of claw and chuck, thereby also influences other part crudy.
The multiple pawl of the scroll chuck that the purpose of this utility model is to provide a kind of simple in structure, easy to manufacture, cost is low, easy to use is used with chuck jaw, can increase work efficiency effectively and the car system quality of part in addition.
To achieve these goals, the utility model adopts following technical scheme: a kind of multiple pawl of scroll chuck, comprise chuck jaw, it is characterized in that: the chuck jaw head is a dismountable type cylinder, one side of this dismountable type cylinder is provided with a groove vertically, and the side of this dismountable type cylinder is provided with the fastening bolt through hole vertical with this recess sidewall.
Good effect of the present utility model is: with the supporting use of the chuck jaw of scroll chuck, can be according to the processed surface configuration of part in addition, select arbitrarily required chuck jaw head, various parts in addition of car system are very easily increased work efficiency and the car system quality of part in addition; Car system cake class is part in addition, need not chuck jaw leading edge car is become step; When freezing if desired, freeze, need not chuck jaw pulled down and freeze, guaranteed the quality of fit of chuck jaw and chuck as long as the chuck jaw head pulled down.
Below in conjunction with drawings and Examples the utility model is elaborated.

The utility model chuck jaw head is a dismountable type cylinder, and a side of this dismountable type cylinder is provided with a groove vertically, and the side of this dismountable type cylinder is provided with the fastening screw inspection through hole vertical with this recess sidewall.
See also Fig. 1 to shown in Figure 5, it is preferred embodiment of the utility model, this chuck jaw head 10 is cylindric body, one side of cylinder is provided with a groove 11 vertically, one sidewall upper edge of this groove is axially arranged with a positioning key 12, and a side of cylinder is provided with the through hole 13 of the fastening bolt vertical with this recess sidewall.
See also Fig. 6 again to shown in Figure 10, it is another preferred embodiment of the utility model, this chuck jaw head 20 is the prism-shaped body, one side of cylinder is provided with a groove 21 vertically, one sidewall upper edge of this groove is axially arranged with a positioning key 22, and a side of cylinder is provided with the through hole 23 of the fastening bolt vertical with this recess sidewall.
During the supporting use of the chuck jaw 30 of the utility model and scroll chuck, only need chuck jaw 30 1 sides are processed the positioning spline 31 that a positioning key 12,22 with chuck jaw head recess sidewall mates, during use, chuck jaw head positioning key is aimed at the chuck jaw positioning spline and is inserted, chuck jaw head and chuck jaw is fastening by the fastening screw inspection through hole that is located on the chuck jaw head side simultaneously with bolt 40, can enter duty.
