Abstract

The invention discloses a tapered tension spring clamping device which is characterized by comprising a shaft, a fixed cone, a spring, a tapered tension spring, a movable cone and a mandrel. The fixedcone is fixedly mounted on the shaft, the movable cone sleeves the shaft, the spring is disposed between the movable cone and the fixed cone, and the spring sleeves the shaft. The mandrel is insertedin a center hole in one end of the shaft and is connected with the shaft through a movable pin. The exposed end of the mandrel is provided with a flange, and the flange can position the movable cone.The movable cone is provided with a material return pin. One end of the tapered tension spring is placed on the conical surface of the fixed cone, and the other end of the tapered tension spring is placed on the conical surface of the movable cone. The tapered tension spring clamping device is simple in structure, convenient to operate, safe and reliable. According to the tapered tension spring clamping device, rigidity of the tapered tension spring clamping device is enhanced, cutting vibration in the processing process is reduced, and processing precision is improved.

Description

Technical field [0001] The invention relates to a conical expansion spring clamping device. Background technique [0002] At present, with the continuous development of mechanical processing technology for military and civilian products, the processing accuracy of products is constantly improving. With the development of modern science and technology, product structure design is becoming more and more sophisticated, which requires both light weight and reliability to increase the effective load, which puts forward higher requirements on mechanical processing technology devices. The cylindrical tapered thin-walled parts have attracted the attention and attention of the machining industry because of their small wall thickness difference (≤0.05mm), weak rigidity and extremely easy deformation. Due to different product shapes and processing methods, the positioning and clamping methods are also quite different, and the processed products cannot meet the product design requirements. ...
