Disclosed is a numerical control machining clamp for a control plane part. The numerical control machining clamp comprises a base, and a positioning device, a clamping device and an auxiliary device which are arranged on the base. A workpiece is arranged in the middle region of the base and fixed by the positioning device, the clamping device is arranged at the periphery of the base and clamps theworkpiece, and the auxiliary device is arranged at the periphery of the surface of the base for being fixedly connected to a machine tool. The positioning device comprises a fixed supporting column,a floating supporting column, a side positioning column and a tool positioning column. The clamping device comprises a hydraulic power mechanism, a rotation compressing oil cylinder and a pressing head. The auxiliary device comprises a hanging ring screw for being connected with the machine tool and a connecting hole for being fixed to the machine tool. The control plane part can be effectively and rapidly clamped, the problems that the control plane part clamping reliability is low, and the clamping force is not consistent are solved, the production period is shortened, the machining precision is improved, the automatic degree is high, beneficial contributions are made to boosting of the overall progress of the control plane part, and the high technical content and the high economic valueare achieved.
Description
technical field [0001] The invention relates to a technology in the field of mechanical manufacturing, in particular to a numerically controlled machining fixture for rudder surface parts. Background technique [0002] As the main load-bearing components of missiles and other aircraft, the rudder surface parts are generally realized by high-strength titanium alloy rudder surface at this stage, but the processing performance of titanium alloy is poor, and the material removal rate is high during the rudder surface processing process. Easy to deform. Rudder surface parts mainly adopt the traditional clamping method of mechanical pressure plate clamping, which has many problems such as long clamping time, low clamping reliability, and unguaranteed clamping force and consistency. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes a numerical control machining fixture for rudder surface parts, which ca...
