The tooling clamp 2 is driven to move along the annular guide rail 14 by the friction force of the conveyor belt 4. Each zone is provided with a set of brakes 6 for braking at the tooling fixture 2.

To improve the sag of the middle section of the conveyor belt 4. The driving wheel sets 8 are set into 2 groups and are respectively arranged at two sides of the conveyor belt 4, and the two groups of driving wheel sets 8 are respectively used for tensioning the conveyor belt 4 at the corresponding sides. Each set of driving wheel 8 includes two rotating wheels 81 rotatably connected in the frame 1, the two rotating wheels 81 are respectively located at the trisection point of the same-side conveyor belt 4, and the same-side conveyor belt 4 surrounds one circle between the two rotating wheels 81. The driving part is specifically a motor 3, and the motor 3 is coaxially connected with one rotating wheel 81. The conveyor belt 4 can run horizontally in the endless track 14 under the drive of the motor 3.

Referring to fig. 4 to 6, since the conveying direction of the conveyor belt 4 is changed when the conveyor belt is wound around the driving wheel set 8, in order to reduce the probability of the conveyor belt 4 deviating, a limiting plate 15 is arranged between the two rotating wheels 81 of each set, and the limiting plate 15 is horizontally fixed in the rack 1.
