Description

A compress tightly chuck anchor clamps behind claw for work piece centre gripping Technical Field The utility model relates to the technical field of machine manufacturing, in particular to a chuck clamp, which relates to a post-claw compacting chuck clamp for workpiece clamping. Background In the machine manufacturing industry, in order to clamp and fix a workpiece to be processed, a post-jaw compression chuck clamp is required, which is a clamp for clamping the workpiece and is characterized in that workpieces with different shapes and sizes are adapted by a back-pull design, the clamping device has the advantages that workpieces of different shapes and sizes can be clamped, rapid machining of the workpieces is facilitated, accordingly, working efficiency and precision are improved, the clamp of the rear compression chuck can be operated in a manual, pneumatic and hydraulic mode, and manual alignment steps can be saved. The existing clamp for the rear compression chuck needs to be clamped through more structures when in use, the problem of lower efficiency of workpiece machining exists, the cost of operators and equipment is increased, the machining efficiency is improved, the cost can be better saved, meanwhile, the clamp plate can not be quickly disassembled and assembled, the replacement and maintenance efficiency is improved, and the market circulation is improved. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide the clamp for the clamp chuck after the claw for clamping the workpiece, which can solve the problems that the existing clamp chuck after the claw needs to be clamped through more structures in a matched manner when in use, the efficiency of workpiece processing is low, the cost of operators and equipment is increased, the processing efficiency is not favorably improved, the cost is better saved, the clamp plate can not be quickly disassembled and assembled, the replacement and maintenance efficiency is not favorably improved, and the market fluxion is not favorably improved. The technical aim of the utility model is achieved through the following technical scheme that the clamp comprises two hinge fixing seats and clamping assemblies which are symmetrically arranged, wherein the clamping assemblies are arranged between the two hinge fixing seats, the clamping assemblies are used for clamping and fixing workpieces, each clamping assembly comprises a threaded switching disc and a positioning pin, the positioning pin is arranged above the threaded switching disc in a penetrating manner, pull plates are fixedly sleeved on the outer fixing plates, two pull rods which are positioned on two sides of the positioning pin are symmetrically arranged on the pull plates, pressing plates hinged with the hinge fixing seats are respectively arranged on the pull rods, sliding grooves are formed in the side walls of the pressing plates, pins I which are fixedly arranged on the side walls of the pull rods in a penetrating manner are arranged in the sliding grooves in a penetrating manner, and pins II which are fixedly arranged on the side walls of the hinge fixing seats in a penetrating manner are arranged on the side walls of the pressing plates in a penetrating manner. Through adopting above-mentioned technical scheme, be connected between screw thread adapter plate and the lathe, when needs carry out the centre gripping to the work piece, through placing the work piece between two clamp plates and hugging closely the locating pin, through moving screw thread adapter plate downwards, screw thread adapter plate descends and can make the locating pin lose the support, the locating pin descends and can drive the arm-tie and descend, and can drive the work piece and descend, the arm-tie descends and can pull the pull rod and descend, the arm-tie descends and can drive the pin and descend, the pin descends and can pull down the clamp plate through the spout, owing to wear to establish the lateral wall at the clamp plate after the lateral wall of hinge fixing base again, so the second clamp plate can carry out spacingly to the lower extreme of clamp plate, the clamp plate only can rotate along the center pin of second clamp plate, so the clamp plate can rotate downwards after receiving decurrent pulling force, the clamp plate moves to the direction that is close to the work piece when keeping away from the one end decurrent of second clamp plate, the clamp plate both sides can extrude the both sides of work piece, can be fixed to the work piece centre gripping. The utility model is further characterized in that a positioning diamond pin is fixedly arranged above the positioning pin in a penetrating way.
