The utility model discloses a motorcycle front magnetorheological damper and motorcycle, including working cylinder, guider assembly, piston assembly, floating piston assembly, magnetorheological fluid, outer tube support assembly, ECU control unit and sensor, guider assembly, piston assembly and floating piston assembly are located in the inside of working cylinder, and piston assembly includes built -in solenoid and damping passage, and damping passage penetrates the upper and lower end of piston assembly, and magnetorheological fluid fills the working cavity between guider assembly and floating piston assembly, and, outer tube support assembly is at least partially coated in the outside of working cylinder, and is connected with guider assembly, and ECU control unit and solenoid electric connection are used for the signal adjustment input to solenoid's current according to sensor, like this through solenoid and the combination of magnetorheological fluid, ECU control unit can real -time regulation magnetic field intensity, change the viscosity of magnetorheological fluid to dynamic control damping force.

This invention provides a welding device for industrial robot manufacturing, relating to the field of welding equipment technology. It includes a welding mechanism mounted at one end to the end of a robot body via a connecting mechanism. The connecting mechanism includes a floating column mounted on the end of the robot body, a floating disk axially and slidably passing through a floating cavity within the floating column, a floating rod with one end vertically positioned at the center of the floating disk's end and the other end movably extending through the end of the floating column, a resistance adjustment component mounted on the floating column and controlling the sliding resistance of the floating disk within the floating cavity, a fine-tuning component mounted at one end of the floating rod, and a control system electrically connected to both the adaptive floating component and the welding mechanism. The control system controls the sliding resistance of the floating disk through the resistance adjustment component based on feedback information from the welding mechanism's operation. A through hole is provided on the end face of the floating disk. This invention achieves adaptive floating adjustment and rapid, precise attitude adjustment of the industrial robot welding device.
