Polishing device achieving fixing of automobile plastic parts with various sizes

Abstract

The invention relates to the technical field of automobile parts, and discloses a polishing device achieving fixing of automobile plastic parts with various sizes. The polishing device comprises a fixing base, wherein the plastic part is movably connected with the interior of the fixing base, a static contact is fixedly connected to the reverse side of the fixing base, and a compression part is movably connected to the reverse side of the fixing base and is close to the obverse side of the static contact. According to the polishing device achieving fixing of the automobile plastic parts with various sizes, extrusion rods drive rubber rings to operate, then dielectric plates and positive plates are used cooperatively, when the rubber rings extrude the plastic part, the internal pressure of fluid grooves is increased, and therefore pistons are driven to operate, and the relative area between each negative plate and the corresponding positive plate can be increased. When the circuit voltage of each negative plate is larger than the access voltage of the corresponding piezoresistor, the fluid grooves are electrified, and therefore the purpose that electrorheological fluid is converted into a solid state from a liquid state is achieved, the clamping force of the plastic part is effectively guaranteed, the clamping damage to the plastic part is avoided, and the intelligent manufacturing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a grinding device for realizing the fixing of various sizes of auto plastic parts. Background technique [0002] Nowadays, there are more and more car brands and types. Auto parts are the units that constitute the whole car and the products that serve the car. There are many kinds of auto parts, mainly including body parts, engine parts, etc. Auto parts need to be It carries out a series of processing such as heat treatment, grinding and polishing, and the fixing is very limited when grinding some plastic accessories, and the fixing force is not easy to grasp, resulting in excessive deviation of grinding accuracy. [0003] When the existing equipment fixes and polishes the plastic parts of automobiles, it cannot fix plastic parts of various shapes, which leads to the limitation of the fixing device, thereby reducing the production efficiency, and it is easy to have too much cl...
