Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a device for clamping a viscous damper. Background Art

[0002] A damper is a device that provides resistance to movement and dissipates movement energy. During the production process of existing dampers, qualified dampers need to be manually press-fitted with sealing gaskets and other components one by one into their inner cavities.

[0003] A Chinese patent discloses a clamping device for damper production, with publication number CN215317197U, comprising a support frame, a motor, a first transmission rod and a first clamping arm. The side walls and the bottom end of the support frame are both open, and a motor is arranged at the top of the support frame. The output end of the motor extends to the inner cavity of the support frame and is provided with an output worm. The inner cavity of the support frame is provided with a first transmission rod and a second transmission rod respectively through a rotating shaft. The support frame, the motor, the first transmission rod and the first clamping arm of the clamping device for damper production are connected in sequence, with a simple structure and low investment cost. The control motor can drive each group of clamping arms to rotate through the meshing connection mode of the output worm gear and the transmission worm and the series cooperation of each component thereof, thereby realizing the clamping work of the damper, and the clamping efficiency and the clamping stability are relatively high, effectively solving the problems existing in the prior art.

[0004] However, the following disadvantages are still included: the device starts the motor and uses the output worm and the transmission worm gear to make the first clamping arm and the second clamping arm clamp the damper, but the device cannot change the clamping angle of the damper, which may cause inconvenience in the installation of the sealing gasket. Therefore, we propose a device for clamping a viscous damper to solve this problem. Utility Model Content
