[0036] Working principle of the first clamping transfer device:

[0037] A feeding pit and a discharging pit are respectively arranged on both sides of the support column. The initial position of the clamping manipulator is located above the feeding pit. The first rotating motor controls the first rotating shaft to rotate so that the two clamping claws of the clamping manipulator rotate to the vertical plane. The lifting motor controls the screw rod to rotate so that the manipulator connecting seat drives the clamping manipulator to descend into the feeding pit. Figure 6 As shown, after the operator rolls the rim G to be assembled between the clamping jaws, the operator controls the clamping manipulator to clamp the rim to be assembled;

[0038] The lifting motor controls the screw rod to rotate so that the manipulator connecting seat drives the clamping manipulator to rise to the specified assembly height. The first rotating motor controls the first rotating shaft to rotate so that the two clamping claws of the clamping manipulator rotate to the horizontal plane. The second rotating motor controls the second rotating shaft to rotate the driving fixed seat, thereby driving the manipulator connecting seat to rotate so that the clamping manipulator rotates to the specified assembly position. The operator completes the assembly of the spoke and the rim at the specified assembly position.

[0039] The second rotating motor controls the second rotating shaft to rotate the driving fixed seat, thereby driving the manipulator connecting seat to rotate so that the clamping manipulator rotates to the top of the discharge pit. The first rotating motor controls the first rotating shaft to rotate so that the two clamping claws of the clamping manipulator rotate to the vertical plane. The lifting motor controls the screw rod to rotate so that the manipulator connecting seat drives the clamping manipulator to descend into the discharge pit, controls the clamping manipulator to release the assembled rim, and the operator rolls the assembled rim out from between the clamping claws for the next process.

[0040] The lifting motor controls the screw rod to rotate so that the manipulator connecting seat drives the clamping manipulator to rise to the specified reset height. The second rotating motor controls the second rotating shaft to rotate the driving fixed seat, thereby driving the manipulator connecting seat to rotate and rotating the clamping manipulator to the initial position.

[0043] The pneumatically controlled chute can adjust the height and width. The working principle of width adjustment is:

[0044] Determine the spacing between the two track slot plates according to the actual size of the wheel, and then determine the position of the first limiting hole corresponding to the spacing. Then, under the premise of ensuring that the center line of the wheel is consistent with the center line of the chute, symmetrically adjust the position of the track slot plates. When the second limiting hole on the sliding sleeve reaches the specified position of the first limiting hole, insert the first locating pin into the second limiting hole and the first limiting hole in sequence.

[0045] How height adjustment works:

[0046] When the first set of the second limiting structure is used, the height of the chute is determined according to actual use requirements, and then the position of the third limiting hole corresponding to the height is determined, and the rotating support foot is rotated. When the fourth limiting hole reaches the position of the specified third limiting hole, the second positioning pin is inserted into the third limiting hole and the fourth limiting hole in sequence;

[0047] When the second set of second limiting structures is used, the height of the chute is determined according to actual use requirements, and then the scale of the arc hole corresponding to the height is determined, and the rotating support foot is rotated.
