The gasket retaining device 500 and the knock pin retaining devices 300, 300 are lowered, the gasket P of the gasket retaining device 500 is placed on the mating surface of the engine case W, and the gasket pin retaining device 30 is lowered.
Insert the 0.300 mm dowel pins N and N into the notch holes on the mating surface of the engine case W. Thereafter, the seal holding device 500 and the knock pin holding devices 300, 300 are raised by the vertical movement cylinder 74.

Thereafter, this engine case W with the knock pins N, N and the knock pin P installed is moved along with the pallet 4 to another device on the conveyor 3, and the pallet 4 with the new engine case W placed thereon is returned to a predetermined position on the conveyor 3. After the head is positioned and fixed, the moving head 40, temporary head 60, etc. repeat the same operation.

(Effects of the invention) As is clear from the above, according to the invention, the dowel pins taken out from the parts feeder are placed on the table device to form a set of packings to be held on the table device, and these are assembled into the packings. After placing the knock pins on the knock pin temporary placement device, move the temporarily placed knock pins to the predetermined positions of the temporarily placed gaskets, adjust the positional relationship between the gaskets and the dowel pins, and simultaneously place them on the mating surface of the case. Since they are assembled, there is no waste in the movement of the seal and the dowel pin, and the seal and the dowel pin can be assembled to the mating surface of the case using a relatively simple and compact device.

In addition, the knock pin can be positioned below the notch hole of the seal by the knock pin moving device for the seal placed on the seal temporary stand of the seal/knock pin temporary positioning device, so the relative positional relationship between the seal and the knock pin is accurately determined and the case can be aligned. It becomes easy to assemble the seal and lock pin to the surface at the same time.

Furthermore, since the entire device is automated, the difficult work of fitting and assembling the dowel pins into the notch holes on the case mating surface can be left to the machines, reducing the burden on the workers. At the same time, work efficiency can be improved.
