[0002] The servo-driven rotation system of the tire gripping manipulator of the tire shaping vulcanizing machine is installed on the lifting frame, and the power is transmitted to the transmission shaft. The transmission shaft drives the tire gripping manipulator to rotate into and out of the tire gripping position and the tire unloading position through the rotating arm.

[0003] In the servo-driven rotation system, the reducer is provided with a special mounting seat, the servo motor is installed on the reducer, the mounting seat is fixed on the lifting frame by bolts, and the transmission shaft is fixed at the output end of the reducer and passes through the mounting seat and the lifting frame.

[0004] Because the mounting seat needs to cooperate with the press-fitting of the bearing, when installing the whole servo-driven rotation system, the transmission shaft needs to be pre-installed on the reducer, and at the same time, the reducer mounting seat is also fixed on the reducer. After pre-installing the upper bearing on the transmission shaft, the whole is hoisted. The installation is very complicated. During later maintenance, when disassembling and assembling the servo motor and the reducer, since it is very difficult to disconnect the transmission shaft from the reducer, the whole is taken out, and the maintenance is difficult and costly.

The rotating mechanism drives the tire gripping manipulator to rotate into and out of the tire gripping position and the tire unloading position through the rotating arm. The difference is that:

[0007] 1. The lifting frame includes an upper frame plate and a lower frame plate installed on the sliding seat.

[0008] 2. The rotating mechanism includes a servo motor, a reducer and a transmission shaft. The reducer is installed on a cylinder seat, the cylinder seat is welded on the upper frame plate, the servo motor is installed on the reducer, and the rotating shaft of the servo motor is connected to the input shaft of the reducer.

The rotating arm is installed on the lower part of the transmission shaft, and the upper part of the transmission shaft is connected to the output shaft of the reducer inside the cylinder seat.

[0018] The technical solution of the present utility model will be further described below in conjunction with the embodiments shown in the drawings.

[0019] The servo-driven speed-reducing rotating device of the tire gripping manipulator of the present utility model includes a rotating mechanism provided based on a lifting frame.

[0020] The lifting frame includes an upper mounting plate 1 and a lower mounting plate 10 arranged in parallel. The left parts of the upper mounting plate 1 and the lower mounting plate 10 are mounted on a slide base 7, and the slide base 7 is slidably mounted on a vertical guide rail. Upper and lower bearing seat holes are coaxially provided on the right parts of the upper mounting plate 1 and the lower mounting plate 10, and a cylinder base 6 is welded on the upper mounting plate 1 coaxially with the bearing seat holes, as Figure 1 shown.

[0021] The rotating mechanism includes a servo motor 3, a speed reducer 4, and a transmission shaft 5.

[0022] The speed reducer 4 is coaxially mounted on the positioning hole at the opening of the cylinder base 6, the servo motor 3 is mounted on the speed reducer 4, and the rotating shaft of the servo motor 3 is coaxially connected to the input shaft of the speed reducer 4, as Figure 1 shown.

[0023] The transmission shaft 5 penetrates through the upper mounting plate 1 and the lower mounting plate 10. The lower part of the transmission shaft 5 is respectively installed and positioned on the upper mounting plate 1 and the lower mounting plate 10 through the upper bearing assembly 8 and the lower bearing assembly 9. The upper bearing assembly 8 and the lower bearing assembly 9 are respectively arranged in the bearing seat holes of the upper mounting plate 1 and the lower mounting plate 10. The upper bearing assembly 8 includes an upper bearing seat installed in the corresponding bearing seat hole and a ball bearing installed between the upper bearing seat and the transmission shaft 5. The lower bearing assembly 9 includes a lower bearing seat installed in the corresponding bearing seat hole and a roller bearing installed between the lower bearing seat and the transmission shaft 5. The upper part of the transmission shaft 5 is coaxially connected (with a detachable mounting structure) to the output shaft extending downward from the speed reducer 4 in the cylinder seat 6. At least one operation port is opened on the side of the cylinder seat 6 at the connection position of the transmission shaft 5 and the output shaft, so that maintenance personnel can disassemble and install the transmission shaft 5 and the output shaft through the operation port. After disconnecting the connection between the transmission shaft 5 and the output shaft, the speed reducer 2 and the servo motor 3 can be smoothly disassembled for maintenance, as Figure 1 shown.

[0024] A rotating arm 2 is provided between the upper mounting plate 1 and the lower mounting plate 10. The rotating arm 2 is sleeved on the lower part of the transmission shaft 5 and is connected by a key to achieve synchronous rotation of the two. The tire gripping manipulator is installed on the rotating arm 2, as Figure 1 shown.

[0025] In the above structure, the cylinder seat 6 is a welded part, which replaces the mounting seat of the speed reducer 4 in the traditional technology and reduces the manufacturing cost. The positioning holes for the installation of the speed reducer 4, the upper bearing seat holes on the upper mounting plate 1, and the lower bearing seat holes on the lower mounting plate 10 can be processed in one-time clamping, with extremely high coaxiality, laying a foundation for the high-stable operation of the rotating mechanism.

[0026] The operation mode of the present utility model is as follows:

[0027] The servo motor 3 is started. The speed of the servo motor 3 is reduced by the speed reducer 4 and then drives the transmission shaft 5 to rotate slowly. The transmission shaft 5 drives the tire gripping manipulator to rotate into and out of the tire gripping position and the tire unloading position through the rotating arm 2, as Figure 1 shown.
