- the holding panel 37 of the radial restraint member 14 has a lower panel constant than the guide panel 36 of the conversion guide member 35, so that the guide The spring 36 does not easily contract elastically. Therefore, the pressure-receiving portion 44 of the presser 34 moves radially outward along the guide surface 43 of the conversion guide member 35 in accordance with the descending movement of the lift base 13. As a result, the holding panel 37 of the radial constraint member 14 is further elastically contracted. That is, the conversion proposal member 35 descends with respect to the radial restraint member 14. Then, the pressing element 34 that moves in the radially outer direction with respect to the holding housing 38 causes the contact portion 30 to contact the inner peripheral surface of the rim drop portion 78 (see FIG.
- the rim support piece 15 arranged on the lower surface of the lifting pedestal 13 comes into contact with the rim flange 73 from above. Further, the core outlet pad 11 passes through the rod insertion hole 21 of the rotary table 20, and the clamp portion 25 of the core outlet pad 11 projects below the rotary table 20. Then, when the rim support piece 15 presses the rim flange portion 73 with a predetermined pressing force, the drive of the elevation drive device 3 is stopped (see FIG. 7).
- the contact portion 30 of the pressing element 34 described above is It comes in contact with the drop section 7 8.
- the rim 71 whose radial position has been determined is pressed by the rim support piece 15 as the elevating rotary unit 7 further descends, and the presser 34 holds the radial position. .
- the pressing force applied to the rim 71 from the rim support piece 15 also acts on the direct drive motor 17 via the rotary table 20.
- this pressing force is such that the above-described radial restraining member 14 can operate to determine the radial position of the rim 71, the rim 71 and the disk 72 are thereafter sandwiched. Sufficiently smaller than the clamping pressure to be applied. For this reason, the pressing force acting on the direct drive motor 17 is so small that it does not affect the drive of the direct drive motor 17 and does not pose a problem.
- the air cylinders 27, 27 of the rod connecting device 24 are driven to move the gripping arms 26, 26 inside the diameter. Operate in the direction. Then, as shown in FIG. 3, the clamp arms 26, 26 grip the clamp portion 25 of the core outlet pad 11 projecting downward from the rotary table 20 from both radially outer sides.
- the centering rod 11 and the rotating table 20 are connected. Thus, the centering rod 11 and the turntable 20 can be integrally operated.
- the mouth pulling device 1 2 is driven to pull the core outlet pad 11 upward, and the lifting drive device 3 is driven again, so that the rim support piece 15 is moved to the rim flange portion 7 3. Is pressed down.
- the turntable 20 is also pulled upward.
- the disc supporting piece 23 disposed on the turntable 20 pulls the joint area of the disc 72 upward.
- the hub mounting portion 81 of the disk 72 is also pulled upward by the disk center support portion 22.
- both the forces are equal to those of the disk 72 and the rim. Almost all are used for clamping pressure to clamp 7 1. For this reason, such a load due to the pinching pressure does not act on the rotating frame 19 and the direct drive motor 17.
- the rim support piece 15 presses the rim flange portion 73 downward, and the disk support piece 23 pulls the joining area of the disk 72 upward, so that the radial position can be precisely adjusted.
- the determined rim 71 and the disc 72 are pressed from above and below along the center axis X.
- the force for pinching the rim 71 and the disk 72 directly acts on the joint portion between the rim 71 and the disk 72.
- the rim 71 has the rim drop portion 78 restrained in the radially outward direction by the radial restraining member 14, the deformation in the radial direction is suppressed, and the rim 71 is formed in the joint area.
- the squeezing pressure helps to work properly.
- the pressing force and the pulling force required to clamp the rim 71 and the disk 72 do not act on the direct drive motor 17 that rotates the rotary table 20. For this reason, the pressing force of the lifting drive device 3 and the pulling force of the rod pulling device 12 can be further increased, and the clamping force for pressing the rim 71 and the disk 72 can be further increased. As a result, the rim 71 and the disk 72 are brought into a state of being pressed by a strong clamping force.
- the pressing force and the pulling force are set so that the pinching force becomes a strong force that can completely suppress thermal distortion caused by welding heat during welding described later.
- the rim 71 and the disk 72 are positioned in the radial direction with high precision in this way, brought into a crimped state by a strong clamping force, and then joined by arc welding. That is, by driving the air cylinder 52 of the welding device 50 described above, the welding torch 51 is advanced to a position where the rim 71 and the disk 72 can be welded and stopped (see FIG. 2). Then, the direct drive motor 17 is driven at a predetermined rotation speed, and the welding torch 51 starts arc welding in synchronization with the rotation of the turntable 20. This allows the crimped state The rim 7 1 and the disc 7 2 are welded in the circumferential direction.
- the whole of the elevating and lowering rotary unit 7 rotates with respect to the elevating and lowering frame 5 according to the rotation of the rotary table 20. Then, when the turntable 20 makes a complete rotation with respect to the welding torch 51, the drive of the direct drive motor 17 is stopped, and the welding by the welding torch 51 is stopped. At the time of this welding, as described above, the state in which the rim 71 and the disk 72 are pressed together by the strong clamping force is maintained, so that thermal distortion caused by welding heat can be almost completely suppressed. . In addition, since the rotary table 20 is directly rotated by the direct drive motor 17, there is no backlash, and a large torque is continuously and stably controlled and generated. 0 can be rotated uniformly and smoothly. Thus, the welding quality between the rim 71 and the disc 72 is improved and stabilized.
- the welding torch 51 is retracted. Then, the tension operation of the rod tension device 12 is stopped, and the load is removed. Thereby, the clamping force acting on the disc 72 and the rim 71 is released. Further, the gripping arm 26 of the rod connecting device 24 is retracted to release the connection between the core outlet pad 11 and the rotary table 20. Thereafter, the lifting / lowering unit 3 is driven to move the lifting / lowering frame 5 to move the lifting / lowering rotating unit 7 upward.
- the elevating platform 13 moves up, the holding panel 37 of the radial restraining member 14 elastically expands, and the distance from the elevating platform 13 increases.
- the conversion guide member 35 also moves upward, the pressing element 34 is released in the elastic contraction of the pressing panel 33 and moves in the radial direction.
- the contact portion 30 of the pressing element 34 is separated from the inner peripheral surface of the rim drop portion 78, and the restraint of the rim drop portion 78 by the radial restraining member 14 is released.
- the lifting / lowering unit 7 moves up, when the stripper bolt 42 reaches the maximum movable length, the radial restraining member 14 moves up together with the lifting stand 13. The Thus, the lifting / lowering rotating unit 7 moves upward as a whole and stops (see FIG. 4). Thereafter, the full face wheel 70 for the automobile, which is formed by welding the disc 72 and the rim 71 on the rotary table 20, is removed, and the assembly welding operation is completed.
- the rim disc assembling apparatus 1 of the full face wheel for a vehicle allows the centers of the disc 72 and the rim 71 to coincide with high precision and suppresses the thermal distortion due to welding.
- a full face wheel 70 for automobiles manufactured by meat welding is manufactured. Further, the welding quality becomes high and the high quality can be stably generated.
