Abstract

The invention discloses a lathe chuck. The lathe chuck comprises a chuck body, wherein a planetary speed reduction mechanism is coaxially arranged in the chuck body, the output end of the planetary speed reduction mechanism is connected with a spiral slot disc in the chuck body, and a resistance moment input mechanism is movably connected to the input end of the planetary speed reduction mechanism. The spiral slot disc follows the chuck body to achieve synchronous rotation, when the input end of the planetary speed reduction mechanism is connected with the resistance moment input mechanism, the spiral slot disc rotates relative to the chuck body, and in this way, a plurality of claws connected with the spiral slot disc move simultaneously in the radial direction of the chuck body. According to the lathe chuck, by controlling the resistance moment input from the outside, workpiece clamping force is freely adjusted. Besides, through the further utilization of a numerical control system,the opening and closing positions of the jaws can be controlled. The lathe chuck has large clamping stroke and multiple control functions, the labor intensity is lowered, the protection efficiency isimproved, and meanwhile, machining automation of a lathe is convenient to implement.

Description

technical field

[0001] The invention relates to the technical field of machine tools, in particular to a lathe chuck. Background technique

[0002] The lathe has a development history of more than 200 years. As the chuck for clamping the workpiece, it is also continuously improved and perfected. The most mature and widely used is the flat spiral disk mechanical chuck, which is realized by rotating the flat spiral disk to drive the jaws to move. Clamping of the workpiece. With the improvement of machine tool processing automation, hydraulic chucks, pneumatic chucks, and electric chucks have appeared one after another. This type of power chuck does not need to manually clamp the workpiece. The outstanding advantages are low labor intensity, high efficiency, and high degree of automation. But there are also great limitations. Hydraulic chucks and pneumatic chucks are mainly reflected in the limited clamping stroke. They are suitable for batch processing of workpieces with simi...
