Are supported by the automatic transmission support 5. Automatic transmission 101
The input shaft 107 on the automatic transmission support 5
The stator shaft 108 is supported in a state in which the stator shaft 108 extends in the vertical direction and the tip protrudes upward, and the position is fixed by the positioning and fixing means 70.

Next, at the supply stage X, the torque converter 102 is held by the assembly device 3. The assembling device 3 is moved to the supply stage X by the moving device 2, and is arranged at a position above the torque converter 102 mounted on a pallet (not shown) at the supply stage X. Then, it is lowered with the opening / closing claw 32 of the chuck portion 30 spread. Due to this lowering, the attachment 33 comes into contact with the torque converter cover 103, the projection 103d of the torque converter cover 103 is fitted into the centering hole 34, and the torque converter cover 103 is centered and positioned on the chuck portion 30.

When the centering arrangement of the torque converter cover 103 is confirmed by the centering arrangement confirmation sensor 35, the opening / closing claw 32 is closed and the outer periphery 103b of the torque converter cover 103 is gripped. As a result, the torque converter 102 is movably held by the chuck unit 30 while being suspended.

The torque converter 102 is connected to the chuck 30
Is held in the universal joint 40 by the regulating means 60.
Movement is regulated. Specifically, when the locating pin 63 is fitted into the locating hole 64, the axis of the driven portion 42 is arranged coaxially with the rotation axis of the rotating shaft 21, thereby restricting the movement of the driven portion 42 with respect to the main driving portion 41. I do.

When the movement of the universal joint 40 is regulated by the regulating means 60, the assembling device 3 is moved from the supply stage X to the assembling stage Y by the moving means 2. At this time, the torque converter 102 is moved while being suspended by the chuck unit 30 and is arranged at a position above the automatic transmission 101.

Then, the assembling device 3 assembles the torque converter 102 to the automatic transmission 101. First, the rotating unit section 20 is lowered by the lifting / lowering means 10, and the torque converter 102 held by the chuck section 30 approaches the automatic transmission 101 supported by the automatic transmission support section 5 at a position below the torque converter 102. You.

Then, the input shaft 107 and the stator shaft 108 are inserted into the cylindrical portion 103a, and the phases of the spline holes 105a and 106a of the turbine runner 105 and the stator 106 are adjusted.
And each spline shaft 107a of the stator shaft 108,
108a and the torque converter claws of the cylindrical portion 103a coincide with the positions of the key grooves of the oil pump rotor 109, respectively.
The spline shafts 107a and 108a are respectively fitted to 6a, and the spline shafts 107a and 108a are lowered to a height position where the torque converter claws and the key grooves are engaged.

During the lowering, the tip of the cylindrical portion 103a passes through the position in which the bearing hole 111 is inserted into the oil seal 112, so that the regulation of the universal joint portion 40 by the regulation means 60 is released. .

Further, by moving the assembling device 3 in a state in which the movement of the universal joint 40 is restricted, an excessive load on the elastic member 43 due to the inertial force at the time of moving the stage can be prevented.

When the phase position of each spline hole 105a, 106a does not coincide with the phase position of each spline shaft 107a, 108a when the rotation unit section 20 is lowered to the above-mentioned height position, each spline shaft 107a,
Each spline hole 105a, 106
The side end surfaces of the oil pump rotor 109 are placed on the side end surfaces of the oil pump rotor 109, respectively. In this state, the floating means 50
Of the floating plate 53 is moved in a direction approaching the fixed plate 51, that is, upward. Therefore, the fitting completion confirmation sensor 55 detects an unfit state based on the approach of the fixed plate 51.

When the non-fit state is detected by the fit completion confirmation sensor 55, the rotation operation control of the rotary shaft 21 of the rotary unit 20 is started. The rotation shaft 21 is rotated at an arbitrary rotation angle, a rotation speed, and a rotation direction (forward / reverse rotation direction) according to a pattern set in advance by, for example, an experiment performed in advance.

When the rotating shaft 21 is rotated, the chuck 30 is rotated via the universal joint 40 and the chuck 3 is rotated.
The torque converter cover 103 of the torque converter 102 held at 0 is rotated coaxially with the axis of the input shaft 107 and the stator shaft 108.

At this time, since the chuck portion 30 is floatingly supported by the floating means 50 so as to be movable in the vertical direction, the spline shafts 107a, 107
The force for pressing the side end surfaces of the spline holes 105a and 106a against the front end surface of the 08a is appropriately adjusted.
By changing the lowering position of the rotary unit 20 by the elevating means 10, the pressing force thereof can be easily adjusted.

Accordingly, the rotation of the turbine runner 105 and the stator 106 is prevented, and the input shaft 107 is prevented from rotating.
By rotating the spline holes 105a and 106a relative to the stator shaft 108, the phase positions of the spline holes 105a and 106a can be matched with the phase positions of the spline shafts 107a and 108a.

When the phase position of each spline hole 105a, 106a matches the phase position of each spline shaft 107a, 108a, the side end surface of each spline hole 105a, 106a is pressed against the tip surface of each spline shaft 107a, 108a. The released state is released, and the turbine runner 105 and the stator 106 move downward in the axial direction, and engage with the input shaft 107 and the stator shaft 108.

Further, by the rotation of the torque converter cover 103, the position of the torque converter pawl of the cylindrical portion 103a matches the position of the key groove of the oil pump rotor 109, and the torque converter cover 103 moves downward in the axial direction. The tip of the cylindrical portion 103a is the oil pump rotor 1

When the spline holes 105a and 106a are fitted into the spline shafts 107a and 108a and the torque converter pawl engages with the key groove, the floating plate 53
By separating from the fixed plate 51 and detecting the separation by the fitting completion confirmation sensor 55, the fitting completed state is detected, and control for stopping the rotation of the rotary shaft 21 based on the detection of the fitting completed state is performed. Done.

Then, the grip of the torque converter cover 103 by the opening / closing claw 32 is released, and the torque converter 1
02 is released, and the rotating unit 20 is raised. With the above operation, the automatic assembly of the torque converter 102 to the automatic transmission 101 is completed.

On the other hand, when the mating completion confirmation sensor 55 does not detect the mating completion state even after a preset time has elapsed since the rotation of the rotary shaft 21 started, the mating device 3 In operation, it is determined that mating is difficult,
The swing operation by the torque converter swing device 80 is performed.

This operation is performed when a predetermined time elapses from the start of the rotation operation of the rotary shaft 21.
In order to separate the torque converter 102 from the torque converter 102, the rotation of the rotary shaft 21 of the rotary unit 20 is stopped, the grip of the torque converter cover 103 by the opening / closing claw 32 is released, and the holding of the torque converter 102 by the chuck 30 is released. Then, the rotating unit 20 is raised.

The rotating unit 20 is raised and the assembling device 3
Is separated from the torque converter 102, the arm portion 81 of the torque converter swing device 80
And the holding portion 83 is arranged at a position above the automatic transmission 101.

The assembling device 3 separated from the torque converter 102 is connected to the torque converter 102 to be assembled next.
Is moved to the supply stage X by the moving device 2 to receive the

When the holding unit 83 is disposed above the automatic transmission 101 by the arm unit 81, the holding unit 83 is lowered by the vertical movement cylinder 84 and the holding hole 86 of the swing block 85 is held.
The protrusion 103d of the torque converter cover 103 is inserted and held therein, and is swung in a preset order by the moving cylinder 82 of the arm 81 and the opposing cylinders 88 and 89 of the holding part 83, which are swing means. .

FIG. 8 is a conceptual diagram illustrating the swing operation of the projection 103d by the torque converter swing device 80. First, the cylinder rod of the opposed cylinder 88 is projected to swing the swing block 85 away from the opposed cylinder 88, and the center point of the projection 103d of the torque converter cover 103 moves from the point a to the point b. The protrusion 103d is swung as described above.

Here, since the cylindrical portion 103a of the torque converter cover 103 is inserted into the bearing hole 111 of the automatic transmission 101, the torque converter cover 103
Are inclined with respect to the axes of the input shaft 107 and the stator shaft 108.

Next, the cylinder rod of the moving cylinder 82 is contracted by a predetermined stroke to swing the swing block 85 toward the moving cylinder 82 so that the center point of the protrusion 103d is shifted from the point b. The projection 103d is swung so as to move to the point c.

By this swing, the torque converter cover 103 swings such that the projection 103d is swung toward the moving cylinder 82 with the axis thereof inclined with respect to the axes of the input shaft 107 and the stator shaft 108. Be moved.

Then, the cylinder rod of the opposing cylinder 88 is contracted and the cylinder rod of the opposing cylinder 89 is protruded to swing the swing block 85 in a direction away from the opposing cylinder 89, so that the center point of the projection 103d is The protrusion 103d is swung so as to move from the point c to the point d.

By this swing, the torque converter cover 103 swings such that the projection 103 d is swung toward the opposing cylinder 88 while the axis is inclined with respect to the axes of the input shaft 107 and the stator shaft 108. Be moved.

Then, the cylinder rod of the moving cylinder 82 is again projected to move the swing block 85 in the projecting direction of the moving cylinder 82 so that the center point of the projection 103d moves from the point d to the point e. Then, the protrusion 103d is swung.

As a result, the torque converter cover 10
Reference numeral 3 denotes a state in which the axis is inclined with respect to the axis of the input shaft 107 and the stator shaft 108, and the projection 103 d is swung so as to swing in a direction away from the moving cylinder 82. When the swing block 85 is swung, the projecting portion 87 of the holding hole 86 is in line contact with the projecting portion 103d, so that the projecting portion 103d can be smoothly swung without rattling.

By the above operations, the swing block 85
Can be swung so as to orbit on a horizontal plane, and the torque converter cover 103 can be swung three-dimensionally so that the so-called rotating coma rotates around the center of rotation while shaking the head.

When the torque converter cover 103 is three-dimensionally swung, the turbine runner 105 and the stator 106 move the input shaft 107 and the stator shaft 1 on the tip surfaces of the spline shafts 107a and 108a.
08 is rotated and oscillated in an inclined state where the axis is decentered with respect to the axis.

Therefore, the turbine runner 105 and the stator 106 aggressively make the phase positions of the spline holes 105a, 106a coincide with the phase positions of the spline shafts 107a, 108a on the tip surfaces of the spline shafts 107a, 108a. Moved to

Therefore, each spline hole 105a, 106
a can be matched with the phase position of each spline shaft 107a, 108a, and the turbine runner 105
And the stator 106 can be fitted to the input shaft 107 and the stator shaft 108.

When the spline holes 105a and 106a are fitted to the spline shafts 107a and 108a, the fitting completion confirmation sensor 55 detects the fitting completion state. Based on the detection of the completion of the fitting, the holding portion 83 rises to release the holding of the projection 103d, retracts to the side position of the opening 72 by the contraction of the arm portion 81, and the positioning support plate 71 is raised. Then, the automatic transmission 101 can be taken out of the automatic transmission support portion 5. By the above operation, the torque converter 102 is connected to the automatic transmission 101.
Can be assembled automatically.

According to the torque converter assembling apparatus 3, the universal joint 4 is provided between the rotary shaft 21 and the chuck 30.
0, the torque converter cover 1
03 can be rotated with the axis of the input shaft 107 and the axis of the stator shaft 108 aligned. Therefore, the spline holes 105a and 106a can be easily fitted to the spline shafts 107a and 108a.

Further, since the outer periphery 103b of the torque converter cover 103 is gripped and rotated by the opening / closing claw 32, the rotation starting torque of the servo motor 23 can be reduced. Therefore, a small servomotor 23 can be used, and the entire device can be downsized. In addition, outer circumference 1
03b, the torque converter cover 10
3 can be made smaller than gripping the central part. Therefore, it is possible to prevent a clamp mark from being generated on the outer periphery of the torque converter cover due to the holding of the opening / closing claw 32.

By providing the overload preventing means 45 in the universal joint portion 40, when a force greater than a predetermined force acts between the main driving portion 41 and the driven portion 42, the universal shaft coupling portion is provided. 40 can be prevented from being overloaded. Further, the floating means 5 is provided separately from the overload prevention means 45.
By providing 0, even when a load is applied to the universal joint portion 40, the chuck portion 30 can be rotated while being floating supported. Therefore, for example, the torque converter cover 103 in a state in which the tip of the cylindrical portion 103a is engaged with the oil pump rotor 109 can be rotated in a state of being floatingly supported by the chuck portion 30, and the spline hole 10 of the stator 106 can be rotated.
6a is a spline shaft 108a of the stator shaft 108.
Can be easily fitted.

On the other hand, according to the torque converter oscillating device 80, the oscillating block 85 is oscillated so as to orbit on a horizontal plane, whereby the torque converter cover 103 is oscillated.
Can be rotated and rocked three-dimensionally.

Therefore, the turbine runner 105 and the stator 106 are connected to the input shaft 107 and the stator shaft 10 on the end surfaces of the spline shafts 107a and 108a.
8 can be rotated and oscillated in an inclined state in which the axis is eccentric and deviated.

[0099] By this rotation swing, each spline hole 10
The phase positions of 5a and 106a are determined by the respective spline shafts 107a,
It can be positively moved to coincide with the phase position of 108a. Therefore, the turbine runner 105 and the stator 106 can be quickly and easily fitted to the input shaft 107 and the stator shaft 108, respectively.

Further, the stroke and the moving speed of the cylinder rod of the moving cylinder 82 and the cylinder rods of the opposed cylinders 88 and 89,
By changing the operation order and the like, the operation pattern such as the distance, speed, and rotation direction of moving the swing block 85 on the horizontal plane is changed, and the torque converter cover 1 is changed.
The inclination angle, swing speed, rotation direction, and the like of 03 can be arbitrarily set and easily changed. Therefore, the setting can be changed according to the type of the torque converter 102, and it is possible to cope with various torque converters 102, so that the device can have high versatility.

Further, the torque converter oscillating device 80
The two-dimensional simple operation of moving the swing block 85 on a horizontal plane allows the torque converter cover 1 to move.
03 is rotated three-dimensionally, so that the apparatus can be realized with a simple configuration. Therefore, the apparatus can be manufactured at low cost, and the equipment cost can be reduced. In addition, good maintainability can be obtained.

The present invention is not limited to the above-described embodiment, and various changes can be made without departing from the gist of the present invention. For example, in the above-described embodiment, the lifting / lowering means 10 is configured to move the rotary unit 20 up and down. However, for example, the automatic transmission supporting unit 5 may be moved up and down.
