閉塞してしまうという不具合が解消できるとしている。According to this, a connector equipped with a port dedicated to supplying and discharging hydraulic oil is directly connected to the cylinder body from the outside by electric resistance welding so as to communicate with a hydraulic oil passage opened in the cylinder body. The inside of the cylinder body and the port communicate with each other. The connector mounting structure using this welding method is said to be able to eliminate the problem that the oil passage would be narrowed and blocked by a sag caused by a melted "goat" on the cylinder side or the connector side.

If an attempt is made to force welding by increasing the resistance welding current in order to solve this problem, the above-mentioned "sagging" phenomenon will be promoted. If this droop reaches the inside of the cylinder body, there is a problem in that the piston seal member is damaged when the piston seal member is inserted into the cylinder body and assembled.

流体給排ポート用コネクタの取付方法の提供を目的とし
ている。The present invention has been made to eliminate such problems with the conventional connector mounting structure, and eliminates welding drips from occurring in the oil passage communicating between the port and the inside of the cylinder or inside the cylinder. It is an object of the present invention to provide a method for attaching a connector for a fluid supply/discharge port that does not block an oil passage and can avoid damage to a piston seal member.

（実施例）
以下、本発明による流体給排ポート用コネクタの取付方
法の実施例について図を参照しつつ説明する。(Example) Hereinafter, an example of a method for attaching a fluid supply/discharge port connector according to the present invention will be described with reference to the drawings.

ている。FIGS. 1(a) and 1(b) show a first embodiment. A flat portion 2 is formed on a cylindrical body 1 of a power cylinder. The size of the flat portion 2 is approximately slightly larger than the diameter of the welded joint portion of the connector 3, which is the welded joint partner and is provided with the hydraulic oil supply/discharge port 3a. In addition, the connector 3 is formed into a tapered shape around the joint part with the cylinder body 1, and has a flat part 4 on the head part in preparation for the joint with the flat part 2 of the cylinder body 1. There is.

様に溶着することができる。The flat parts 2 and 4 of the cylindrical body 1 and the connector 3 that have been set up in this manner are brought into contact with each other and positioned as shown in FIG. 1(a). After this, a predetermined welding voltage is applied to the connector 3 side. At this time, since the joint portions of the cylinder 1 and the connector 3 are formed flat, it is possible to weld them uniformly over the entire surface of the flat portions 2 and 4 even with normal standard electric resistance welding. Can be done.
筒体１にコネクタ３が溶接結合されてのち、第１図（ｂ
）に示されるように、ボール盤等の穿孔工作機によって
、コネクタ３の給排ポート３ａ側から筒体１に向かって
これらを貫通する油路５が穿孔される。After the connector 3 is welded to the cylindrical body 1, as shown in FIG.
), an oil passage 5 is bored from the supply/discharge port 3a side of the connector 3 toward the cylindrical body 1 using a drilling machine such as a drilling machine.
一方、第２図（ａ）、（ｂ）は第２実施例を示している

する大きさの平坦な係合凸部８が突出成形されている。On the other hand, FIGS. 2(a) and 2(b) show a second embodiment. In this case, the cylindrical body 1 of the first embodiment described above is subjected to counterbore processing to form a flat portion. That is, one cylindrical body 1 has a flat counterbore recess 7 of a required size.
A flat engagement protrusion 8 having a size to fit into the counterbore recess 7 is projectingly formed on the other connector 3 .
したがって、第２図（ａ）に示されるように、座ぐり凹

In addition, the cylindrical body 1 and the connector 3 can be joined together by welding with good engagement.

油路９が穿孔されるのである。After the cylindrical body 1 and the connector 3 are connected, as shown in FIG.
), an oil passage 9 is drilled from the supply/discharge port 3a side of the connector toward the cylindrical body 1 in the same manner as in the first embodiment.
なお、上記第１、第２実施例においては、コネクタ３を
筒体１に対して、より良好に溶接結合させるために筒体

Since this is a method in which the oil passage is drilled so that it communicates toward the body side, weld drips will not occur in the oil passage that communicates with the port and the inside of the cylinder, or in the cylinder, thereby blocking the oil passage. This will no longer occur, and damage to the piston seal member will not occur.
