Description

Quick clamping device is used in aluminium bar processing Technical Field The utility model relates to the technical field of aluminum bar processing equipment, in particular to a quick clamping device for aluminum bar processing. Background The aluminum bar is a cylindrical bar-shaped object made of pure aluminum material, and aluminum has good workability and is easy to cut, splice and mold. This allows the aluminium bar to be custom machined as required to accommodate various shapes and sizes, and in order to prevent the deflection of the workpiece during machining, it is generally necessary to clamp the workpiece using a clamping device. Most of existing clamping devices use threaded rods to drive clamping blocks to move to clamp workpieces, but when the moving stroke of the clamping blocks is too long, the clamping blocks can be moved to corresponding positions only by rotating the threaded rods for a plurality of circles, and therefore time is wasted in use. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides a quick clamping device for aluminum bar processing, which solves the technical problems. (II) technical scheme The quick clamping device for aluminum bar processing comprises a device main body, wherein a transmission cavity is formed in the device main body, two transmission sliding blocks are mounted in the transmission cavity in a sliding mode, tooth grooves are formed in one side, close to each other, of each transmission sliding block, a transmission gear meshed with the tooth grooves is rotatably mounted in the center position of the transmission cavity, the two transmission sliding blocks are meshed with the transmission gear, two mutually symmetrical rectangular sliding holes are formed in the inner wall of the top of the transmission cavity, butt joint blocks penetrating through the rectangular sliding holes and extending to the outside are convexly arranged at the tops of the two transmission sliding blocks, movable blocks are mounted on the two butt joint blocks, two guide rods are mounted on the movable blocks in a sliding mode, the same end of each guide rod is provided with the same movable mounting plate, rubber blocks are mounted on the movable mounting plate, V-shaped grooves are formed in one side, far away from the movable mounting plate, one end of each guide rod is sleeved with a buffer spring, the other end of each buffer spring is abutted to the movable block, one end, far from the movable mounting plate is provided with a corresponding guide rod, one end, far from the main body is provided with a hydraulic cylinder, and one side of each hydraulic cylinder is mounted on the hydraulic cylinder is provided with one side of the hydraulic sliding blocks. Preferably, an access hole communicated with the transmission cavity is formed in the bottom of the device main body, an access cover is arranged at the access hole, and the access cover is connected with the device main body through a fixing bolt. Preferably, two track rods are arranged in the transmission cavity, and the two transmission sliding blocks are respectively arranged on the two track rods in a sliding manner. Preferably, two mutually symmetrical clamping grooves are formed in the movable mounting plate, and two mutually symmetrical clamping blocks matched with the clamping grooves are arranged on the rubber block. Preferably, the movable block is provided with a butt joint groove matched with the butt joint block, and the movable block is fixedly connected with the butt joint block through a connecting bolt. Preferably, a plurality of protruding blocks are arranged on two inner walls of the V-shaped groove of the rubber block at intervals along the axial direction. Preferably, the bottom of the device main body is convexly provided with four support columns, and the four support columns are distributed at the bottom of the device main body in a matrix. Compared with the prior art, the quick clamping device for processing the aluminum bar has the advantages that the two transmission sliding blocks are close to each other and drive the two movable blocks to be close to each other, the movable mounting plate which is connected with the movable blocks in a sliding mode and the rubber block on the movable mounting plate are close to each other and can clamp the aluminum bar quickly, the clamping efficiency is improved, the contact area between the V-shaped grooves formed in the rubber blocks and the aluminum bar can be increased, the clamping stability is improved, meanwhile, the buffer spring sleeved on the guide rods can drive the two guide rods to slide on the movable blocks and squeeze the buffer spring after the rubber blocks are contacted with the aluminum bar, and therefore impact force generated during clamping is buffered, and damage to the surface of the aluminum bar due to clamping is avoided.
