摘要:
The aim of the invention is to provide a simple and cost-effective device for joining substrates (2, 3) which allows a secure and exact joining of the substrates and reduces the reject rate. To this end, the invention provides a novel device for joining at least two substrates (2, 3) that comprise one inner hole each and a pin that is adapted to the inner holes of the substrates. Said pin is provided with at least two noses (10) that are radially displaceable with respect to the pin (5). The edges of the inner holes of the substrates glide downwards on the straight outer surfaces of said noses (10) when said noses are displaced towards the pin.

The invention concerns a method for making a motor car body comprising a step for assembling an understructure (1) with box body sides (4a, 4b), the understructure (1) comprising a rigid engine compartment (2) at one end and being placed in a specific position predetermined in an orthogonal benchmark of directions X, Y, Z of an assembly station. The method consists in setting in place and maintaining in position the box body sides (4a, 4b) in the station reference frame using two parallel tools (13, 14) each co-operating with one box body side (4a, 4b) and at least one tool (11) transverse to said parallel tools, the three tools being linked to one another and to the station X Y Z benchmark such that the transverse tool (11) is placed and maintained in a specific position and locked in said benchmark and forms a staying and bracing tool in direction Y for the two parallel tools (13, 14) in a zone distant from the understructure (1) engine compartment (2) and consists in maintaining an applied force (F) of each of the parallel tools (13, 14) at least against the understructure (1) engine compartment (2) lateral sides while the box body sides are being assembled to said understructure.

To produce a flanged pipe unit, a separate flange (1) is put on a pipe (5) and then the pipe is subjected to a punching to achieve an interlocked connection between the flange and the pipe. The flanged pipe unit produced by the method of the invention comprises a metal pipe including a larger expanded portion (5a), a smaller expanded portion(5b) and a raised portion (5b') which are axially aligned so that the smaller expanded portion is placed between the larger expanded portion and the raised portion (3); and a metal flange having a through bore (2) through which the pipe passes, the through bore including a larger diameter portion (3), a smaller diameter portion (4) and a tapered end portion (4a) which are axially aligned so that the smaller diameter portion is placed between the larger diameter portion and the tapered end portion. The larger expanded portion, the smaller expanded portion and the raised portion of the pipe are intimately engaged with the larger diameter portion, the smaller diameter portion and the tapered end portion of the through bore respectively thereby to establish a dove-tail coupling between the pipe and the flange.

A device (10) is provided for fixing a bundle of elongate members (14-18) to a support. The device comprises a locating member (20) which is locatable non-rotatably on the bundle, and a mount (22) adapted to be mounted on the support. The locating member is rotatably fitted to a body (36) of the mount such that the angular orientation of the locating member with respect to the mount can be adjusted to suit the orientation of the bundle to the surface to which it is to be fixed. Additionally, the locating member is movable relative to the mount in the through direction of the device.

The invention provides a press-fitting method of a member and a press-fitting apparatus in which press-fitting errors can be reduced, without using a dummy pin. The pressing jig 45 includes a main body 46 having a guide pin containing part 47 which is open downward, a compression coil spring (a resilient member) 48 which is contained in an upper part of the guide pin containing part 47, a guide pin 49 which is contained in a lower part of the guide pin containing part 47 with its lower end portion projected downward from a lower face of the main body 46 by an urging force of the compression coil spring 48, and a permanent magnet 50 in an annular shape which is fixed to the lower face of the main body 46, as attracting and holding unit for attracting and holding the press-fitting member 11.

The present invention provides a technique which can disassemble a mandrel (11) having a substantially cylindrical shape and being dividable into a plurality of segments (20, 30), easily and efficiently. The disassembling method comprises, in the mandrel adhesively attached with a composite material structure on an outer peripheral surface thereof, a rotation step of rotating the pair of support rings (40) along with the mandrel to position a segment which is a detached target to an uppermost portion; and a segment detaching step of detaching the segment which is the detached target positioned at the uppermost portion, from the pair of support rings; wherein in the segment detaching step, the segment which is the detached target is moved in a vertically downward direction to a position inside of the mandrel, between the pair of support rings, and is carried out from between the pair of support rings.
