The invention discloses a clamping device of a pneumatic gear. The clamping device structurally comprises a chuck body, a base, a first movable jack catch, a first movable jack catch drive mechanism,a gear, a second movable jack catch, a second movable jack catch drive mechanism, a third movable jack catch and a third movable jack catch drive mechanism. The bottom face of the chuck body is connected with the top face of the base. The base is arranged below the chuck body in parallel. The gear making movable contact with the chuck body is arranged at the center position of the top face of thechuck body. The bottom face of the first movable jack catch drive mechanism, the bottom face of the second movable jack catch drive mechanism and the bottom face of the third movable jack catch drivemechanism are movably connected with the chuck body. The clamping device of the pneumatic gear has the beneficial effects that the sliding jack catches of the clamping device are provided with clamping heads which are made of rubber materials, the clamping heads are provided with racks corresponding to the gear, the racks can be in interference fit with the gear, the gear is prevented from being abraded, and the phenomenon that the gear moves can be effectively avoided.
Description
technical field [0001] The invention relates to a pneumatic gear clamping device, which belongs to the field of gear clamping devices. Background technique [0002] A gear is a mechanical element with gears on the rim that continuously mesh to transmit motion and power. [0003] A tooling fixture disclosed in the prior art adopts a three-jaw chuck to clamp the indexing circle of the gear, and grinds the inner surface of the central circular hole of the gear. The three-jaw chuck is composed of a chuck body, movable jaws and jaw driving mechanism. The three-jaw chuck is a machine tool accessory for clamping and positioning the workpiece by using the radial movement of three movable jaws evenly distributed on the chuck body. Under the guide part of the three claws on the three-jaw chuck, there are threads that interfere with the plane threads on the back of the bevel gear. When the small bevel gear is turned with a wrench through the square hole, the bevel gear rotates, and t...
