A kind of structure of described frictional force adjusting part comprises base plate, backing plate and spring, described base plate is installed on the end face of rotating shaft, described backing plate is located on base plate, described spring is placed between backing plate and brake disc, described base plate is provided with adjusting bolt, described adjusting bolt by backing plate by spring compression on brake disc, brake disc realizes adjustment and the auto-compensation of frictional force by the thrust that spring provides.

For realizing the anti-displacement of manipulator fixed point (dress tire and catching tire position), the technological means that can take is: in the compression region of brake disc and frictional disk, four friction plate circumference uniform distributions are located at frictional disk, two projections or the circumference uniform distribution that described brake disc are formed symmetry form four projections, in dress tire and the catching tire position of manipulator, described projection and friction plate are pressed together.

Described damping mechanism can be located at rotating up and down between manipulator pivoted arm and crane simultaneously and locate, or described damping mechanism is only located at upper run-on point place between manipulator pivoted arm and crane or lower run-on point place.

In mounting structure conventionally, described rotating shaft is installed on manipulator pivoted arm, and described bearing block is installed on crane.

Beneficial effect of the present invention:

1, tire forming vulcanizer manipulator non-displacement device of the present invention is arranged on the turned position of manipulator, does not take hosting space, especially for driving mould assembling action vertical lift type vulcanizer, can significantly improve curing efficiency, economize energy.

2, structure of the present invention is simple, itself has no effect to former tire discharging device effect, also can alleviate manipulator and turn into, the vibrations produced and resilience, good stability.

3, the present invention utilizes and applies in turned position the function that fixed point frictional force reaches the anti-displacement of manipulator, and there is not machinery location and locate failure, can not produce security incident, security is good.
