本発明は、紡糸口金の加工用位置決め治具の改
良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a positioning jig for processing a spinneret.
従来の紡糸口金の加工用位置決め治具は、第１
図に示す如く基台１の中央に、口金素材２を嵌入
する円形の段付凹部３を設け、この段付凹部３の
周方向にて複数の押え板４を基台１上に上下動可
能に設けて成るもので、この加工用位置決め治具

え板４を下降して口金素材２の外周縁を押え付け
て固定する。そしてこの状態でドリル或いはパン
チにより口金素材２に紡糸孔を穿設する。 The conventional positioning jig for spinneret processing is
As shown in the figure, a circular stepped recess 3 into which the base material 2 is inserted is provided in the center of the base 1, and a plurality of presser plates 4 can be moved up and down on the base 1 in the circumferential direction of the stepped recess 3. When processing the spinning hole of the spinneret, the processing positioning jig 5 fits the spinneret material 2 into the stepped recess 3 of the base 1 as shown, and lowers the presser plate 4. The outer periphery of the cap material 2 is pressed down and fixed. In this state, a spinning hole is formed in the spinneret material 2 using a drill or a punch.

繁に取り外しているが、再び段付凹部３内に嵌入
した際、元の位置にセツトすることが極めて困難
で、位置の再現性に欠けるものであつた。 By the way, such a processing positioning jig 5 cannot position the spinneret material 2 in the circumferential direction within the stepped recess 3 of the base 1, so it is difficult to cut the polymer introduction hole in the spinning hole drilling process. The cap material 2 is frequently removed from the stepped recess 3 in order to remove debris and clean the cap material 2, as well as to remove bulges and burrs caused by the punch and reamer of the polymer discharge hole. When it was fitted into the recess 3, it was extremely difficult to set it back to its original position, and the reproducibility of the position was lacking.
また前記加工用位置決め治具５は、基台１の段
付凹部３が一定寸法の口金素材２しか嵌入できな
いので、多種類の寸法の異なる口金素材２を位置
決めするには、それに応じた加工用位置決め治具
を多数用意しなければならないものである。 In addition, in the processing positioning jig 5, the stepped recess 3 of the base 1 can only fit the cap material 2 of a certain size, so in order to position the cap materials 2 of various sizes, it is necessary to This requires the preparation of a large number of positioning jigs.
本発明は斯かる実情に鑑みなされたもので、口
金素材を精度良く元の位置にセツトできて、位置

る。 The present invention has been made in view of the above circumstances, and provides a spinneret that allows the spinneret material to be set in its original position with high precision, has high position reproducibility, and can easily position and hold a wide variety of spinneret materials with different dimensions. The present invention aims to provide a positioning jig for machining.
以下本発明による紡糸口金の加工用位置決め治

押圧前進する押え１２が螺通されている。 An embodiment of the positioning jig for processing a spinneret according to the present invention will be described below with reference to FIGS. 2 and 3.
A support block 7 having a planar V-shaped recess 6 at the center of the front is fixed on the base 1.
A pin block 8 is provided at a position facing and spaced apart from the center of the recess 6 to slidably support a pin 9 having a sharp tip, and a guide block 11 having a screw hole 10 is fixed to the rear of the pin block 8. is,
A presser foot 12 for pushing the pin 9 forward is screwed into the screw hole 10 of the guide block 11.

糸孔を穿設する。 The processing positioning jig 13 having such a structure positions the spinneret material 2 in the V-shaped recess 6 in plan view of the support block 7 on the base 1, as shown in the figure, when processing the spinning hole of the spinneret. After the outer peripheral surface of the base material 2 is brought into contact with both sides of the recess 6, the presser foot 12 screwed into the screw hole 10 of the guide block 11 on the base 1 facing the support block 7 is rotated forward. , the tip of the pin 9 is pressed against the outer peripheral surface of the base material 2 to position and hold the base material 2 at three points. In this state, a spinning hole is formed in the spinneret material 2 using a drill or a punch.

る。 In the process of drilling a spinning hole in this nozzle material 2, the cutting waste of the polymer introduction hole is removed and the nozzle material 2 is
Even if the base material 2 is frequently removed from the machining positioning jig 13 to remove bulges and burrs caused by punching and reaming the polymer discharge hole for cleaning, the recess 6 of the support block 7 and pin 9 will be removed again.
When holding and fixing the base material 2, there is a mark on the outer peripheral surface of the base material 2 that was initially made by pressing the pin 9 with a sharp tip, so turn the base material 2 so that the tip of the pin 9 touches this mark. If you set it, you can accurately position and hold it in its original position.

優れた効果がある。 As can be seen from the above explanation, according to the spinneret processing positioning jig of the present invention, the spinneret material is placed in the recess of the support block on the base, and the pin is moved by advancing the presser foot of the guide block. Just by moving it forward, you can easily position and hold the base material at three points. In addition, no matter how many times the cap material is removed from the processing positioning jig, if the cap material is set again so that the tip of the pin touches the mark made by the sharp tip of the pin when it was initially positioned and fixed, it will be restored to its original state. Can be accurately positioned, held and fixed in the desired position. Furthermore, there are excellent effects such as the ability to easily position, hold and fix even base materials of different sizes by appropriately adjusting the amount of advance of the presser foot.
