。Detailed Description of the Invention 1. A stopper jig that can be inserted into and removed from a central axial hole of a three-jaw chuck body, which comprises a cylindrical body that is inserted into the axial hole and extends integrally with the body. three body wall parts which are provided and are divided at equal angles through three notches through which the three claws move forward and backward; A jig body having three substantially fan-shaped locking collars whose lower surfaces are locked to the upper surface of the chuck body when the cylindrical body and body wall are inserted into the axial hole; and the jig body. A nut member having a screw hole coaxially connected to the cylindrical body of the nut member, and the screw hole of the nut member or the jig [Industrial Application Field] When inserted into a jaw chuck, the workpiece is chucked by blocking the end face of the workpiece, which has both long and short lengths and thicknesses (outer diameters), using the three detachable jaws, thereby chucking the workpiece. The present invention relates to a new stopper jig for a three-jaw chuck that can be processed extremely efficiently.
高速精密加工あるいは強力重切削等を行なう旋盤機械に
装着の三ツ爪チャックは周知である。Three-jaw chucks installed on lathe machines that perform high-speed precision machining or powerful heavy cutting are well known.
ところで、従来三ツ爪チャック用としてはこれと言った

物を生爪でチャキングし、加工していた。By the way, there is no special stopper jig for conventional three-jaw chucks, and when the workpiece to be machined is gripped by three jaws, the chucking dimension must be measured with a tool each time, and the chucking must be done with a melon. Alternatively, machine a locking step of a predetermined size on each of the three raw jaws according to the workpiece, attach these three machined raw jaws to the chuck body, and lock the end face of the workpiece to the three locking steps. At the very least, I was chucking the workpiece with my raw nails and machining it.

ために、それの労力と時間が大変であるばかりか。Therefore, in the former of the conventional techniques, the chucking dimensions of the workpiece must be measured with a tool each time, which is very complicated, requires a great deal of time and effort, and is inefficient. , there is a problem of poor workability, and in the latter case, when machining a large number of workpieces with different lengths and thicknesses, it is necessary to perform step machining on three raw jaws with dimensions that suit each workpiece. Not only does it take a lot of effort and time to do so, but it also requires a lot of effort and time.
実に多くの生爪を必要とし、また三つの生爪の取り換え
作業に多大の時間と労力を要し、更には生爪であるため
に消耗が早くてコスト高になってしまうという問題点が
あった。There are problems in that a large number of natural nails are required, a great deal of time and effort is required to replace the three natural nails, and furthermore, the natural nails wear out quickly, resulting in high costs.

ある。The present invention was made in view of the problems of the prior art, and its purpose is to process raw nails,
There is no need to replace the chuck at all, and the chuck dimensions can be set accurately with simple handling, and workpieces of both long and short lengths and thicknesses (outer diameters) can be handled with the three-jaw chuck. To provide a stopper jig for a three-jaw chuck that can be chucked and processed with extremely high efficiency.

ングし、加工する。Next, to explain how to use it, for example, the chucking dimension of the workpiece W with a three-jaw chuck (assuming the height from the top surface of the chuck body 1 to the top end of the jaws 2 is 40 m) is 5 m.
01 m, the length of the protruding portion of the bolt member as the stopper member 24 from the through hole 18 in the jig body 10 is adjusted to ensure that the end surface of its tip portion 25 is engaged with the jig body 10. If the distance between the flange 16 and the lower surface 17 is set to 10 mm, the distance will be 40 m + + 10 mm = 50 m. Therefore, the bolt member is fixed by tightening the lock nut 28, and in this state, the chuck is opened by opening the three jaws. After fitting into the axial hole 3 of the main body 1 and locking with the locking collar 16, and firmly inserting this stopper jig, the end face of the workpiece W is inserted into the stopper member (bolt member) 24.
The three melon pieces 2 are used to chuck and process the melon.
以下、同一寸法の工作物にあっては、本ストッパー治具

If you want to change it to
If the stopper member (bolt member) 24 is moved forward by its screw movement by loosening the bolt, and the end surface of the tip portion 25 is made to protrude 30 mm from the lower surface of the locking collar portion 16, the distance is 40 m.
-30ms = 10I, so lock nut 2

、かつ低コスト的に行なうことができる。According to the present invention, the length of the protruding portion from the axial hole of the jig body can be adjusted appropriately by a simple operation of screwing or sliding the stopper member, and the three-jaw chuck can be used. Since the chucking dimensions can be set, once the chucking dimensions are set, workpieces with the same chucking dimensions can be processed by chunking continuously without having to measure the dimensions one by one as in the conventional method. Even if you want to change the king dimensions, you only need to take out one jig and reset the stopper part.Inserting and removing this jig from the chuck body can be done by opening the three jaws and using the axial hole. It only needs to be pulled out or inserted, and there is no need for the complicated work of machining the three free jaws to create a step and replacing them each time (bolting them), making the work extremely easy. This can be done efficiently and at low cost.

な工作物まで長さ、厚さの精度、平行度を必要とする工
作物まで三ツ爪チャックの***でチャッキングし、加工
することができる。Furthermore, according to the present invention, there is no need to process or replace the raw jaws as in the past, so there is no labor or time loss, and there is no need to make any structural changes to the existing three-jaw chuck. It is possible to chuck and process workpieces from small to large outside diameters that require precision in length, thickness, and parallelism with the three-jaw chuck.
また本発明によれば、チャック本体に対する挿脱は固定
具を一切要することなく、単に嵌挿し、また引き出すだ
けのきわめて簡易な操作でよいから、取り扱い簡易であ
って、迅速になし得て作業性が著しく向上する。Furthermore, according to the present invention, insertion and removal from the chuck body do not require any fixing tools, and can be performed by simply inserting and removing the chuck, making it easy to handle, quick, and workable. is significantly improved.
