Abstract

The invention discloses a mechanical clamping device with magneto-rheological fluid shock absorption, which includes a base, the upper end of the base is fixedly connected with baffle plates symmetrically on both sides, and a circular card slot is provided on one side of the outer wall of the baffle plate , and a circular block is arranged in the circular card slot, a lead screw is connected between the two circular blocks, and the middle outer wall of the lead screw is sleeved with a rotating block, and the outer walls of both ends of the lead screw are A clamping plate is socketed, and the clamping plate is threadedly connected with the lead screw. The bottom of the clamping plate is provided with a slider, and the upper end of the base is provided with a chute corresponding to the slider. The inner wall of the baffle is a A sleeve is fixedly connected to the side, and the inner cavity of the sleeve is filled with magnetorheological fluid. The inner wall of the sleeve is provided with a piston block, and one end of the piston block is connected with a support rod. The invention is simple in structure, easy to operate, has better stability, and keeps the clamping force constant within a certain range at the same time, avoiding damage to the workpiece.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a mechanical clamping device with magnetorheological fluid shock absorption. Background technique [0002] In the process of machining, workpiece fixtures are needed, and vibration often occurs. It will not only leave vibration marks on the processed surface, but also affect the processing quality of the workpiece, poor stability, and aggravate the wear of the tool. In order to solve this Many methods have been proposed at home and abroad. Among them, the method of applying damping to control processing vibration has a better vibration reduction effect, and it has a vibration reduction effect on various vibration types. However, since the damping value cannot be adjusted with the change of the dynamic system parameters of the machine tool, its application is also limited. Therefore, it is necessary to find a material with fast response and controllability, and apply...
