Abstract

The invention discloses a positioning clamping device suitable for machining a single-head screw pump rotor. The device comprises a machine tool body, a workbench and a clamping mechanism, wherein the clamping mechanism comprises a base, two sealing covers, an outer shell, an inner shell, a piston plate, a sealing plate, a driving disc and a plurality of clamping jaws, the inner shell is arranged in the outer shell in a sleeved mode, a working cavity is formed between the outer shell and the inner shell, the driving disc, the sealing plate and the piston plate are sequentially arranged in the working cavity, and a first air hole and a second air hole are formed in the outer shell. According to the device, the first air hole and the second air hole are connected with an air source, air is introduced, and the piston plate is pushed to reciprocate in the axis direction of the inner shell, so that the driving disc is driven to reciprocate, the plurality of clamping jaws are driven to synchronously slide along wedge-shaped grooves in the driving disc, contraction and expansion of the clamping jaws are achieved, automatic workpiece clamping and loosening are achieved, workpiece mounting operation is simple and rapid, workpieces can be effectively clamped, and the machining precision of the workpieces is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fixtures, and more specifically relates to a positioning and clamping device suitable for processing single-head screw pump rotors. Background technique [0002] Whirlwind milling is a cutting device for high-speed machining of threads, worms, and spheres that is matched with CNC machine tools. It is a hard alloy forming blade installed on a high-speed rotating cutter head, and is used to mill threads on workpieces. Because of its high milling speed and fast processing efficiency, it can realize dry cutting, heavy-duty cutting, and ultra-high-speed cutting of difficult-to-machine materials. Because of its high speed, the stabilizing device for fixing the workpiece is particularly important. Especially when processing single-head screw pump rotors, due to the long length and variable diameter of the workpiece, the conventional top positioning and clamping method cannot achieve the effect of stabilizing th...
