Have one circular hole 3b. The two bearing insertion circular holes 3b into which a bearing (not shown) is inserted have the same circle, and are arranged to face each other so as to be almost completely coaxial. As can be seen from FIG. 2, the first yoke, that is, the upper yoke 1, has substantially the same shape as the lower yoke 3, and one end in the axial direction branches into two and extends in the axial direction. It has two ends 1a. Like the lower yoke 3, each of the two ends 1a is provided with one circular hole 1b. The two circular holes 1b for bearing insertion are
The circles are substantially the same, and are arranged to face each other so as to be almost completely coaxial. The tubular end 1C of the upper yoke 1
The chuck member 7 attached to the axial moving member 16 having the claw 9 is gripped and gripped, or the grip is released to the extent that the upper yoke 1 is held so as not to fall down.

However, in FIG. 1, the pawl 9 is attached to the chuck member 7 attached to the axial moving member 16, and The chuck member 7 is moved in the reciprocating direction by the piston cylinder and the rack & pinion mechanism, and the axial moving member 16 is
2 shows an example of a parallel chuck capable of moving back and forth by an equal distance with respect to a “vertical movement center axis” that moves forward and backward. The position of the claw 9 in the reciprocating direction is determined by setting the lower yoke 3 to the mounting surface 11a of the pedestal 11.
After the positioning or fixing, the axial moving member 16 is lowered so that the upper yoke 1 does not fall, but the end 1C of the upper yoke 1 can be held so that it can be inserted between the claws 9, that is, the "pressing reference position". And a position where the upper yoke 1 can be gripped and maintained in an axially symmetric manner with respect to the vertical movement center axis of the axial moving member 16 when the alignment by pressing the upper and lower yokes 1, 3 of the present invention is completed, ie, " It is controlled to at least two positions of the “alignment gripping position”.

The axial moving member 16 and the chuck member 7 are used to adjust the position by lifting the pressed upper yoke 1 upward.
The hydraulic cylinder 15 is a cylinder for driving the axial moving member 16 and the chuck member 7 to press the upper yoke 1. Cross 5
Is a commonly used cross-shaped cloth integrally having four pins 5a fitted into the circular holes 1b and 3b.
以上の構成の組立装置において十字継手は、次のよう

が完了する。Also in this assembly, the second yoke is used as the lower yoke 3 and the other pair of pins 5a of the cloth 5 is
The first yoke is used as the upper yoke 1 and the pair of pins 5a of the cloth 5 is fitted in the circular hole 3a of the upper yoke 1 in advance in the circular hole 3a of the lower yoke 3 together with the bearing. An example of the present invention in which the above state is referred to as a cross joint assembly 100 will be described with reference to FIGS. First, two pins 5a of the cloth 5 are inserted in advance into the circular holes 3b, the bearing is inserted, and the lower yoke 3 is joined to one side of the cloth.
Is mounted on the pedestal 11 in a fixed state. Then upper yoke 1
Insert the remaining two pins 5a of the cloth 5 into the circular holes 1b (by hand)
Fit. Therefore, in this state, all the pins 5a of the cloth 5
Are fitted in the circular holes 1b and 3b. In this state, since the bearing is not inserted between the circular hole 1b and the pin 5a in the upper yoke 1 yet, the upper yoke 1 is in an unstable posture with respect to the lower yoke 3 (either in the horizontal direction in FIG. 1). The upper yoke 1 falls down). Then, the axial moving member 16 is lowered, and the claw 9 is set at the “pressing reference position”.
Is manually inserted between the claws 9 on both sides. In this state, the pressing reference of the upper yoke 1 to the lower yoke 3 is completed.

ってくる。From this state, when the cylinder 15 is driven to push the upper yoke 1 downward (when the upper yoke 1 is already in contact with its own weight but is further pressed), the inner peripheral surface of the circular hole 1b and the outer peripheral surface of the pin 5a Are contacted, and the phase shift between the yoke 1 and the cross 5 is corrected by the centripetal action caused by the contact between the arcs. That is, the distance e in FIG. 2 becomes substantially zero. This distance e is represented by the difference between the center O 2 of the center O 1 and the circular hole 1b of the pin 5a in the axial direction of the yoke. At the same time as the correction of the distance e, the upper yoke 1 held at the pressing preparation position has not yet been aligned in the vertical direction with respect to the yoke 3, but the axial moving member 16 further descends and the pressing member 16 a When the pressing surface 16b starts pressing the upper yoke end surface 1d between the pressing surface 16b and the mounting surface 11a of the pedestal 11, the upper yoke 1 held so as to lean on the claw 9 gradually moves upward and downward with respect to the lower yoke 3. Standing in the right posture.

3C is parallel to the upper yoke 1
1b and the pin 5a of the cross are parallel to the bearing insertion direction, and at the same time, the distance e described in FIG. 2 is also corrected, so that the axis center of the pin 5a and the center of the circular hole 1b are " The upper yoke 1 is present on the vertical movement center axis, that is, in a correct posture state with respect to the lower yoke 3,
The conditions before inserting the bearing are set. In other words, the state is "at the time of completion of alignment" of the present invention. Thereafter, the end portion 1C of the upper yoke 1 at which the claws 9 are aligned and gripped is advanced so as to be in a gripping state, and the edge portion 1C of the upper yoke 1 is gripped and maintained. Thereafter, the cylinder 13 is further driven to pull up the chuck member 7 by a certain amount.
Is also raised by a certain amount in the axial direction. At the time of this lifting operation, the lifting amount is half of the difference between the diameter of the circular hole 1b and the diameter of the pin 5a (the distance d shown in FIG. 2), which is the distance of the pin 5a in the direction perpendicular to the axial direction of the yoke. Center O 1
Represented by the difference between the center O 2 of the circular hole 1b. )
The pin 5a can be located exactly at the center of the circular hole 1b. In this state, if the bearing is inserted, the yoke 1 and the cloth 5 can be joined without any misalignment.
