The actuator 14 generates a driving force of the valve clinching device according to the present invention as a pneumatic or hydraulic cylinder, and is installed at one end of the conveyor line 10.

The guide line 16 is installed in the same direction as the movement direction of the reciprocating actuator 14 to allow the first and second pressing members 22a and 22b to move along the guide line 16. In the exemplary drawing, the guide lines 16 are installed in a direction perpendicular to the conveying direction of the conveyor line 10, and are provided in pairs on both sides of the object feed table 12 of the conveyor line 10 to form the first and second pressing members ( The movement of 22a, 22b is made to be stable.

The first pushers 18a and 18b are for bringing the first pressing members 22a and 22b into close contact with the object, and are provided at the tip of the actuator. As the first pushers 18a and 18b move in the direction of the object carrier 12 and come into contact with the first pressing members 22a and 22b, the driving force of the actuator 14 is transmitted through the first pushers 18a and 18b. It is to be transmitted to the pressing members (22a, 22b).

The first pressing member (22a, 22b) is independent of the first pusher (18a, 18b) is coupled to the bearing to be transported along the guide line 16 by a linear bearing so as to be able to reciprocate freely, the center of the The first press-fit portions 24a and 24b protrude in the direction of the object feed table 12. The first press-fitting part 24a, 24b is rotatably installed in the vertical direction, and the operator manually inserts the valve 3 to press-fit in a state in which the first press-fitting part 24a, 24b faces upward. give. In the first pressing member (22a, 22b) on which the valve (3) is mounted, the first press-fitting portion (24a, 24b) is rotated in the vertical direction so that the tip of the first press-fitting portion (24a, 24b) and the valve (3) are inserted. The hole of the object to be positioned is positioned in a straight line.

On the other hand, the second pushers 18a and 18b are driven by the actuator 14 so that the first pushers 18a and 18b move to the object side and then move to the object side along the guideline 16 by the reaction force in a lower order. Is installed. Accordingly, it can be seen that the first and second pressing members 22a and 22b have only the time difference by the first and second pushers 18a and 18b in the transmission of the pressing force by the actuator 14 and the same pressing force is transmitted. have.

The second pressing members 22a and 22b have the same shape and structure as the first pressing members 22a and 22b and have a symmetrical structure around the object support. That is, the bearing is coupled so as to be transported along the guide line 16 by a linear bearing. In the center of the second pushers 18a and 18b, second projections 20a and 20b are formed in the direction of the object feed table 12.
