  The insertion portion 26 and the rotating shaft 24 are provided above the transmission 201 so as to rotate coaxially with the input shaft 202 and the stator shaft 203.

  The insertion portion 26 has a configuration that allows the distal end of the insertion portion 26 to be inserted into the fitting hole 206 of the sprocket 205 when the moving base 23 is moved downward. The insertion portion 26 has a substantially cylindrical shape, and a base end is externally fitted to a lower end portion of the rotating shaft 24, and a distal end projects downward from the lower end portion of the rotating shaft 24. The center hole of the insertion portion 26 has a size that allows the input shaft 202 and the stator shaft 203 to be inserted from the distal end of the insertion portion 26.

  The distal end of the insertion portion 26 has an outer diameter smaller than the outer diameter of the fitting portion 214 of the torque converter cover 212, and when the distal end of the insertion portion 26 is inserted into the fitting hole 206 of the sprocket 205, 5, a slight gap is formed between the outer peripheral surface of the distal end of the insertion portion 26 and the oil seal 209, or the oil seal 209 is brought into contact with the oil seal 209 with a pressing force that does not rotate with the sprocket 205.

  The fitting hole phase detection means 28 is disposed at a position facing the rotation shaft 24 with a predetermined distance, and the phase of the insertion portion 26 coincides with a preset phase by the rotation of the rotation shaft 24. Then, the detection state is set opposite to the dog 24a (detected element) fixed to the rotating shaft 24, and a signal indicating that the phase alignment has been performed is set to be output.

  Here, the preset phase means that the torque converter 211 phase-matched by the fitting portion phase detection means 3 in the torque converter cover phase matching stage X is fitted in the sprocket phase matching stage Y. When the sprocket 205 whose phase of the fitting hole 206 has been phased by the hole phase detecting means 28 is opposed to the torque converter assembly stage Z, and the torque converter 211 is moved along the rotation center axis thereof Further, this is a phase in which the fitting portion 214 of the torque converter cover 212 is fitted into the fitting hole 206 of the sprocket 205.

  If the movement of the universal shaft joint portion 70 is restricted by the restriction means 90, next, whether or not the phase of the fitting portion 214 matches the preset phase based on the detection signal of the fitting portion phase detection means 3. Determine whether.

  Here, when the optical axis of the fitting portion phase detection means 3 is shielded by the outer periphery of the fitting portion 214 (see FIG. 16B), it is determined that the phases are inconsistent, and the rotation unit portion 50 To rotate the chuck portion 60.

  The torque converter cover 212 is rotated by the rotation of the chuck unit 60 by the rotating unit 50, and the rotation is stopped when the optical axis of the fitting unit phase detection means 3 is secured (see FIG. 16A). The phase of the combining unit 214 is adjusted to a preset phase.

  When the phase alignment of the fitting portion 214 is completed, the vertical moving portion 34 of the moving device 5 is moved upward while the phase is maintained to move the entire assembly device 6 upward, and the torque converter 211 is moved to the phase alignment position X3. To the rising end position. Then, the horizontal moving unit 32 is moved to move the assembling apparatus 6 together with the torque converter 211 to the torque converter assembling stage Z. Then, the torque converter assembly stage Z holds the torque converter 211 at a position above the transmission 201 in a suspended posture. That is, the torque converter cover 212 is held in a suspended posture in which the rotation center axis of the torque converter cover 212 extends vertically and the fitting portion 214 is positioned below.

[Second step]
On the other hand, when the transmission 201 is conveyed to the sprocket phasing stage Y and positioned and held in the standing posture, the moving base 23 of the sprocket phasing device 4 is moved downward, and the tip of the insertion portion 26 is fitted to the sprocket 205. Insert into hole 206.

  Here, when the phase of the sprocket 205 and the phase of the insertion portion 26 coincide with each other, the insertion portion 26 moves downward integrally with the rotary shaft 24, and the distal end portion of the insertion portion 26 is fitted to the sprocket 205. The fitting detection means 27 detects the fitting state by fitting in the hole 206.

  If the phase of the sprocket 205 and the phase of the insertion portion 26 do not match, the tip of the insertion portion 26 comes into contact with the axial end of each convex portion 207 of the sprocket 205 so that the insertion portion 26 is in contact with the rotary shaft 24. The tip portion of the insertion portion 26 is not fitted into the fitting hole 206 of the sprocket 205, and the fitting detecting means 27 detects the unfitted state. When the sprocket phasing device 4 moves the movement base 23 to the lower end position, the rotation motor 25 is driven to rotate the insertion portion 26, and the insertion portion 26 is based on the detection signal from the fitting hole phase detection means 28. Are phase-matched to a preset phase.

  And the detection signal of the fitting detection means 27 is confirmed, and when the fitting detection means 27 has detected the fitting state, rotation of the insertion part 26 by the rotation motor 25 is stopped. Thereby, the phase of the sprocket 205 can be adjusted to a preset phase.

  Moreover, when the fitting detection means 27 has detected the unfitted state, rotation of the insertion part 26 is continued. Accordingly, the insertion portion 26 is rotated relative to the sprocket 205, and when the phase of the insertion portion 26 and the phase of the fitting hole 206 coincide with each other, the insertion portion 26 is moved downward by its own weight to cause the sprocket 205 to move downward. Thus, the insertion portion 26 and the sprocket 205 can be rotated together.

  Then, based on the detection signal from the fitting hole phase detection means 28, the phase of the insertion portion 26 is adjusted to a preset phase, the detection signal of the fitting detection means 27 is confirmed, and the fitting detection means 27 is confirmed. , The rotation of the insertion portion 26 by the rotary motor 25 is stopped, and the phase of the sprocket 205 is set in advance as a phase that can be engaged with the fitting portion 214 of the torque converter cover 212. Match the phase to the specified phase.

  When the phase alignment of the sprocket 205 is completed, the moving base 23 is moved upward, the tip of the insertion portion 26 is removed from the fitting hole 206 of the sprocket 205, and separated from the sprocket 205. Then, the transmission 201 is transported to the torque converter assembly stage Z by the transport conveyor H2 while maintaining this phase.

[Third step]
In the torque converter assembling stage Z, the transmission 201 is held in a standing posture by the transmission holding means 7, and is positioned and fixed at a preset position by the fixing means 100.

  Then, the vertical moving portion 34 is moved downward by the vertical movement actuator 35, and the torque converter 211 is brought close to the transmission 201 in a state of being held suspended from the chuck portion 60, and is disposed to face the transmission 201.

  Then, the rotary unit 50 is moved downward by the elevating means 40 to insert the tips of the input shaft 202 and the stator shaft 203 into the cylindrical portion 213 from the tip side of the cylindrical portion 213, and the tip of the cylindrical portion 213, that is, the fitting The portion 214 is inserted into the fitting hole 206 of the sprocket 205 through the bearing hole 204.

  Then, the phases of the turbine runner 216 and the spline holes 216a and 217a of the stator 217 coincide with the phases of the input shaft 202 and the spline shafts 202a and 203a of the stator shaft 203, respectively, and the phase of the fitting portion 214 of the torque converter cover 212 is the same. When the phases of the fitting holes 206 of the sprocket 205 coincide with each other, the input shaft 202 and the turbine runner 216, the stator shaft 203 and the stator 217 are fitted, and the fitting portion 214 is fitted in the fitting hole 206. The rotary unit 50 is moved to a fitting height position that is a height position to be joined.

  Here, when the tip of the cylindrical portion 213 passes the position of the oil seal 209 during the downward movement of the rotary unit portion 50, the restriction of the universal shaft joint portion 70 by the restriction means 90 is released. By releasing the restriction, the center of the torque converter cover 212 can be aligned with the axes of the input shaft 202 and the stator shaft 203 of the transmission 201. In addition, during the period from holding the torque converter 211 by the torque converter cover phasing stage X until the cylindrical portion 213 is inserted into the fitting hole 206 of the sprocket 205 at the torque converter assembly stage Z, the universal shaft coupling portion 70 Regulate the movement of Accordingly, unnecessary movement of the chuck unit 60 and the torque converter 211 can be prevented, and the torque converter 211 and the chuck unit 60 can be prevented from coming into contact with a place where contact is not planned, for example, the case of the transmission 201 or the like. . Accordingly, it is possible to prevent the oil seal 209 from being damaged by the tip of the cylindrical portion 213 and from being damaged due to contact with the case portion of the transmission 201 and the like, and to suppress the generation of defective products during assembly work. it can. Further, by moving the assembly device 6 in a state where the movement of the universal shaft joint portion 70 is restricted, it is possible to prevent an excessive load on the elastic member 73 due to the inertial force during the stage movement.

  When the tip of the cylindrical portion 213 is inserted below the oil seal 209 due to the downward movement of the rotary unit 50, the oil seal 209 is interposed between the cylindrical portion 213 and the fitting hole 206, and torque is increased. The fitting portion 214 of the converter cover 211 is inserted into the fitting hole 206 of the sprocket 205, and the torque converter cover 212 and the sprocket 205 are integrally connected to each other so as to be rotatable.

[Fourth step]
When the rotary unit 50 is lowered to the fitting height position, the phases of the turbine runner 216 and the spline holes 216a and 217a of the stator 217 become the phases of the input shaft 202 and the spline shafts 202a and 203a of the stator shaft 203. When they do not match, the side end surfaces of the turbine runner 216 and the stator 217 are pressed against the tip surfaces of the input shaft 202 and the stator shaft 203, respectively, and the floating plate 83 of the floating means 80 is fixed. It moves toward the plate 81, that is, upward. Then, the fitting completion confirmation sensor 85 detects the approach of the floating plate 83 and outputs a signal indicating that it is in the unfitted state to the control unit.

  When the control unit receives a signal indicating a non-fitted state from the fitting completion confirmation sensor 85, the control unit starts rotating operation control of the rotating shaft 51 by the rotating unit 50. The rotation unit 50 rotates the rotation shaft 51 at an arbitrary rotation angle, rotation speed, and rotation direction (forward / reverse rotation direction), for example, according to a pattern set in advance by experiments or simulations performed in advance.

  Therefore, according to the rotation of the rotating shaft 51, the chuck portion 60 and the torque converter cover 212 held by the chuck portion 60 are also rotated together. At that time, since the chuck portion 60 is floatingly supported by the floating means 80 so as to be movable in the vertical direction, the force that presses the side end surfaces of the turbine runner 216 and the stator 217 against the tip surfaces of the input shaft 202 and the stator shaft 203, respectively. Is appropriately adjusted, and the pressing force can be easily adjusted by changing the descending position of the rotary unit 50 by the elevating means 40.

  Therefore, the turbine runner 216 and the stator 217 are prevented from rotating together, and the turbine runner 216 and the stator 217 are rotated relative to the input shaft 202 and the stator shaft 203, and the spline holes 216a and 217a of the turbine runner 216 and the stator 217 are rotated. Can be made to coincide with the phases of the spline shafts 202a and 203a of the input shaft 202 and the stator shaft 203.

  When the phases of the spline holes 216a and 217a of the turbine runner 216 and the stator 217 coincide with the phases of the spline shafts 202a and 203a of the input shaft 202 and the stator shaft 203, the side end surfaces of the turbine runner 216 and the stator 217 are the input shaft 202 and the stator shaft. The state of being pressed against the front end surface of 203 is released, and the turbine runner 216 and the stator 217 move downward due to their own weight and are fitted to the input shaft 202 and the stator shaft 203.

[Fifth step]
When the turbine runner 216 is fitted to the input shaft 202 and the stator 217 is fitted to the stator shaft 203, the torque converter cover 212 moves further downward.

  Since the torque converter cover 212 and the sprocket 205 are coupled together so as to rotate together with the fitting portion 214 and the fitting hole 206 being phase aligned, the turbine runner 216 is fitted to the input shaft 202 and When the stator 217 is fitted to the stator shaft 203 and the torque converter cover 212 moves further downward, the fitting portion 214 and the fitting hole 206 are fitted. Then, the torque converter 211 moves to the final assembly position with respect to the transmission 201.

  When the torque converter 211 moves to the final assembly position, the floating plate 83 is separated downward from the fixed plate 81, and the fitting completion confirmation sensor 85 detects the completion of fitting.

  Then, each open / close claw 62 of the chuck portion 60 is widened to release the gripping of the torque converter cover 212, the rotary unit portion 50 is lifted, and the fixing of the transmission 201 by the fixing means 100 is released, and the transmission 201, that is, the assembly The automatic transmission 200 that has been completed is brought into a state where it can be removed from the transmission holding means 7. With the above operation, the automatic assembly of the torque converter 211 to the transmission 201 is completed.

  On the other hand, if the fitting completion confirmation sensor 85 does not detect the fitting completion state even after a preset time has elapsed since the rotation operation control of the rotating unit 50 is started, the fitting operation by the assembling device 6 is performed. Then, it is determined that the fitting is difficult, and the swing operation by the torque converter swing device 110 is performed.

  In this operation, when a preset time has elapsed from the start of the rotation operation control of the rotation unit 50, first, the rotation operation control of the rotation unit 50 is stopped in order to disconnect the assembly device 6 from the torque converter 211. Then, the gripping of the torque converter cover 212 by the opening / closing claw 62 is released, the holding of the torque converter 211 by the chuck portion 60 is released, and the rotating unit portion 50 is raised.

  When the rotary unit 50 is raised and the assembling device 6 is disconnected from the torque converter 211, the arm portion 111 of the torque converter oscillating device 110 is projected from the side of the opening hole 101a, and the holding portion 113 is moved away from the transmission 201. Place it in the upper position.

  The assembling device 6 separated from the torque converter 211 is moved to the torque converter cover phasing stage X by the moving device 5 so as to receive the torque converter 211 to be assembled next.

  When the holding portion 113 is disposed above the transmission 201 by the arm portion 111, the holding portion 113 is lowered by the vertical movement cylinder 114 and the torque converter boss 219 of the torque converter cover 212 is inserted and held in the holding hole 116 of the swing block 115. Then, they are moved in a preset order by the moving cylinder 112 of the arm portion 111 and the opposing cylinders 118 and 119 of the holding portion 113 which are swinging means.

  FIG. 12 is a conceptual diagram for explaining the swinging operation of the torque converter 211 by the torque converter swinging device 110, and FIG. 13 is a view showing a fitting state of the fitting portion 214 and the fitting hole 206. FIG. FIG. 13A is a view showing a state where the fitting portion 214 is inserted into the fitting hole 206, and FIG. 13B is a view showing a state where the fitting portion 214 is fitted into the fitting hole 206.

  First, the cylinder rod of the opposing cylinder 118 is protruded and the swing block 115 is moved away from the opposing cylinder 118 so that the center point of the torque converter boss 219 of the torque converter cover 212 moves from point a to point b. The torque combo 219 is moved.

  Here, since the cylindrical portion 213 of the torque converter cover 212 is inserted into the bearing hole 204 of the transmission 201, the axis of the torque converter cover 212 is inclined with respect to the axis of the input shaft 202 and the stator shaft 203. The

  Next, the cylinder rod of the moving cylinder 112 is contracted by a preset stroke and the swing block 115 is moved to the moving cylinder 112 side, and the center point of the torque converter 219 moves from the point b to the point c. Thus, the torque combo 219 is moved.

  As a result of this movement, the torque converter cover 212 is swung so that the torque converter 219 side is swung toward the moving cylinder 112 while the shaft center is inclined with respect to the shafts of the input shaft 202 and the stator shaft 203.

  Then, the cylinder rod of the counter cylinder 118 is contracted and the cylinder rod of the counter cylinder 119 is protruded to move the swing block 115 away from the counter cylinder 119, so that the center point of the torque converter 219 is changed from the point c to the point d. The torque combo 219 is moved so as to move to.

  As a result of this movement, the torque converter cover 212 is swung so that the torque converter 219 side is swung toward the opposed cylinder 118 side while the shaft center is inclined with respect to the shaft center of the input shaft 202 and the stator shaft 203.

  Then, the cylinder rod of the moving cylinder 112 is protruded again to move the swing block 115 in the protruding direction of the moving cylinder 112, and the torque converter 219 is moved so that the center point of the torque converter 219 moves from point d to point e. Move.

  As a result, the torque converter cover 212 is swung so that the torque converter 219 side is swung away from the moving cylinder 112 in a state where the axis is inclined with respect to the axes of the input shaft 202 and the stator shaft 203. The Note that when the swing block 115 is swung, the convex portion 117 of the holding hole 116 is in line contact with the torque converter 219, so that the torque converter 219 can be swung smoothly without rattling.

  By the above operations, the swing block 115 can be moved so as to circulate on a horizontal plane, and the torque converter cover 212 is three-dimensionally rotated so that a so-called rotary piece swings around the center of rotation while swinging the head. It can be rotated and swung.

  When the torque converter cover 212 is rotationally oscillated three-dimensionally, the turbine runner 216 and the stator 217 are eccentric with respect to the input shaft 202 and the stator shaft 203 on the tip surfaces of the input shaft 202 and the stator shaft 203. It is rotated and oscillated in a declined inclined state.

  Accordingly, the turbine runner 216 and the stator 217 are arranged such that the spline holes 216a and 217a of the turbine runner 216 and the stator 217 are in phase with each other on the input shaft 202 and the stator shaft 203, and the spline shafts 202a and 203a of the input shaft 202 and the stator shaft 203. It is moved positively to match the phase of.

  Therefore, the rotation of the turbine runner 216 and the stator 217 is prevented and the turbine runner 216 and the stator shaft 203 are rotated relative to each other, and the phases of the spline holes 216a and 217a of the turbine runner 216 and the stator 217 are changed. The phase of the spline shafts 202a and 203a of the stator shaft 203 can be matched.

  When the phases of the spline holes 216a and 217a of the turbine runner 216 and the stator 217 coincide with the phases of the spline shafts 202a and 203a of the input shaft 202 and the stator shaft 203, the side end surfaces of the turbine runner 216 and the stator 217 are the input shaft 202 and the stator shaft. The state of being pressed against the tip surface of 203 (see FIG. 13A) is released, and the turbine runner 216 and the stator 217 are engaged with the input shaft 202 and the stator shaft 203 by moving downward due to their own weight. To do.

  When the turbine runner 216 is fitted to the input shaft 202 and the stator 217 is fitted to the stator shaft 203, the torque converter cover 212 moves further downward due to its own weight, and the torque converter cover 212 of the torque converter cover 212 that has been phase-adjusted in advance. The fitting portion 214 and the fitting hole 206 of the sprocket 205 are fitted (see FIG. 13B).

  In such a fitting state, the fitting portion 214 of the torque converter cover 212 is interposed between the respective convex portions 207 and 207 of the fitting hole 206 of the sprocket 205, and each plane of the fitting portion 214 of the torque converter cover 212. A portion 214a faces each of the convex portions 207 and 207. Therefore, when the torque converter cover 212 is rotated in the forward rotation direction, the sprocket 205 can be rotated integrally by bringing the flat portions 214a into contact with the first flat surfaces 207a and 207a of the convex portions 207 and 207. it can.

  When the fitting portion 214 of the torque converter cover 212 is fitted into the fitting hole 206 of the sprocket 205, the torque converter cover 212 moves to the fitting completion position. The movement of the torque converter cover 212 to the fitting completion position is detected by a fitting completion sensor (not shown) provided in the holding portion 113, and control for stopping the swinging operation is performed.

  Then, the holding portion 113 is lifted to release the holding of the torque comb boss 219, the arm portion 111 is contracted to retract to the side position of the opening hole 101a, the positioning support plate 101 is raised, and the transmission 201 by the fixing means 100 is moved. The fixed state is released, and the transmission 201, that is, the automatic transmission 200 that has been assembled, is brought into a state where it can be removed from the transmission holding means 7. With the above operation, the torque converter 211 can be automatically assembled to the transmission 201.

  According to the torque converter assembling apparatus 6, the fitting portion 214 of the torque converter cover 212 and the fitting hole 206 of the sprocket 205 are phase-matched to each other so that the fitting portion 214 can be fitted in this state. Since the torque converter cover 212 and the sprocket 205 are rotatably connected integrally with each other, the torque converter cover 212 and the sprocket 205 are connected to each other so that the turbine runner 216 is fitted to the input shaft 202 and the stator 217 is fitted to the stator shaft 203. Even if the cover 212 is rotated or swung, the phases of the fitting portion 214 and the fitting hole 206 are not changed, and the phase-matched state is maintained. Therefore, after the turbine runner 216 is fitted to the input shaft 202 and the stator 217 is fitted to the stator shaft 203, the fitting portion 214 of the torque converter cover 212 can be fitted into the fitting hole 206 of the sprocket 205. it can.

  Further, since the torque converter cover 212 and the sprocket 205 can be easily rotated from the outside by the assembling device 6 and the sprocket phase adjusting device 4, respectively, the phase adjusting operation of the fitting portion 214 of the torque converter cover 212 and the fitting of the sprocket 205 are performed. The phase matching operation of the joint hole 206 can be performed quickly and easily. Therefore, the assembling work for assembling the torque converter 211 to the transmission 201 can be performed quickly and easily, the working time required for the assembling work can be shortened, and the production amount can be increased.

  The phase of the fitting portion 214 of the torque converter cover 212 is adjusted by holding the torque converter cover 212 by the chuck portion 60 as a torque converter cover holding means and forming it on the inner peripheral surface of the fitting hole 206 of the oil pump sprocket 205. The torque converter cover 212 is detected by detecting the flat portion 214a formed on a part of the outer peripheral surface of the fitting portion 214 of the torque converter cover 212 that engages the projected portion 207 with the fitting portion phase detection means 3. It is detected whether or not the phase of the fitting portion 214 coincides with a preset phase. When the phases do not match, the torque converter cover 212 is rotated by the rotating unit 50 as the torque converter cover rotating means, and the torque converter cover 212 is fitted based on the detection signal from the fitting portion phase detecting means 3. When the phase of the portion 214 matches the preset phase, the rotation of the torque converter cover 212 is stopped and the phase of the fitting portion 214 of the torque converter cover 212 is adjusted, so that the fitting hole 207 of the oil pump sprocket 205 is The fitting portion 214 of the torque converter cover 212 is based on the plane portion 214a formed on a part of the outer circumferential surface of the fitting portion 214 of the torque converter cover 212 that engages with the convex portion 207 formed on the inner circumferential surface of the torque converter cover 212. Can be reliably matched to a preset phase.

  Further, the phase alignment of the fitting hole 206 of the oil pump sprocket 205 is performed by holding the transmission 201 by the holding means, and depending on the position of the convex portion 207 formed on the inner peripheral surface of the fitting hole 206 of the oil pump sprocket 205. Fitting hole phase detection means determines whether or not the phase of the fitting hole 206 of the oil pump sprocket 205 of the transmission 201 matches a phase preset as a phase that can be fitted to the fitting portion 214 of the torque converter cover 212. 28. When the phases do not match, the oil pump sprocket 205 is rotated by the oil pump sprocket rotating means constituted by the rotating shaft 24, the rotating motor 25, and the insertion portion 26, and based on the detection signal from the fitting hole phase detecting means 28. When the phase of the fitting hole 206 of the oil pump sprocket 205 of the transmission 201 matches the phase set in advance as the phase that can be fitted to the fitting portion 214 of the torque converter cover 212, the rotation of the oil pump sprocket 205 is rotated. The phase of the fitting hole 206 of the oil pump sprocket 205 is stopped and the phase of the fitting hole 206 of the oil pump sprocket 205 is adjusted to the phase that can be fitted with the fitting portion 214 of the torque converter cover 212. With reference to the convex portion 207 formed on the surface, The phase of the fitting hole 206 of the pump sprocket 205, the fitting portion 214 capable of being fitted phase of the torque converter cover 212, can be combined reliably phase.

  As a result, the torque converter cover 212 and the oil pump sprocket 205, which have been phase-adjusted in advance, can be reliably coupled together in the torque converter assembly stage Z.

  Furthermore, according to the torque converter assembling apparatus 1, the transmission 201 is held in the inverted posture and the torque converter 211 is held in the suspended posture and the fitting operation of each part is performed. Therefore, the turbine runner 216 and the stator 217 and the torque converter cover 212 can be urged downward in the assembly direction by its own weight.

  Therefore, the turbine runner 216 is phase-matched to a phase that can be fitted to the input shaft 202, and the phase of the stator 217 is phase-matched to a phase that can be fitted to the stator shaft 203. 202 and the stator 217 can be fitted to the stator shaft 203.

  Further, after the turbine runner 216 is fitted to the input shaft 202 and the stator 217 is fitted to the stator shaft 203, the fitting portion 214 of the torque converter cover 212 can be fitted into the fitting hole 206 of the sprocket 205. it can.

  Further, in the assembling apparatus 6, the rotation unit portion 50 as the torque converter cover rotating means and the chuck portion 60 as the torque converter cover holding means are integrally configured, and the rotation unit portion 50 and the chuck portion 60 are interposed between them. , The floating means 80 for floatingly supporting the chuck unit 60, the rotation axis of the rotation shaft 51 of the rotation unit unit 50, and the eccentricity and declination of the rotation axis of the chuck unit 60, allowing the rotation axis of the rotation unit unit 50 to rotate. The universal joint portion 70 as a universal shaft joint means for movably connecting 51 and the chuck portion 60, and the torque converter 211, that is, the torque converter cover 212 are held, and then the fitting portion 214 of the torque converter cover 212 is connected to the oil pump sprocket. Until the shaft is inserted into the fitting hole 206 of 205, the movement of the universal shaft joint portion 70 is continued. And the fitting portion 214 of the torque converter cover 212 is inserted into the fitting hole 206 of the oil pump sprocket 205 to connect the turbine runner 216 and the stator 217 in the torque converter cover 212 to the input shaft 202 and the stator shaft 203. When the phase of the turbine runner 216 is adjusted to a phase that can be fitted to the input shaft 202 and the phase of the stator 217 is adjusted to a phase that can be fitted to the stator shaft 203, the restriction is released. The control means 90 to intervene is interposed.

  As a result, the torque converter cover 212 is rotated to align the phase of the turbine runner 216 with a phase that can be fitted to the input shaft 202, and the phase of the stator 217 to a phase that can be fitted to the stator shaft 203. At this time, the restriction by the restricting means 90 on the universal shaft joint portion 70 is released, and the chuck portion 60 is floatingly supported by the floating means 80 so as to be movable in the vertical direction, so that the turbine is mounted on the tip surfaces of the input shaft 202 and the stator shaft 203. The forces for pressing the side end surfaces of the runner 216 and the stator 217 are adjusted appropriately, and the pressing force can be easily adjusted by changing the lowered position of the rotary unit 50 by the elevating means 40.

  Therefore, the turbine runner 216 and the stator 217 are prevented from rotating together, the turbine runner 216 and the stator 217 are rotated relative to the input shaft 202 and the stator shaft 203, and the phases of the turbine runner 216 and the stator 217 are changed. And the phase of the stator shaft 203 can be matched.

  Further, by releasing the restriction, the center of the torque converter cover 212 can be aligned with the axes of the input shaft 202 and the stator shaft 203 of the transmission 201.

  On the other hand, during the period from holding the torque converter cover 212 to inserting the fitting portion 214 of the torque converter cover 212 into the fitting hole 206 of the oil pump sprocket 205, the movement of the universal shaft joint portion 70 is controlled by the regulating means 90.
