Description

Gear turning quick positioning device Technical Field The utility model relates to the technical field of gear machining, in particular to a quick positioning device for gear turning. Background Currently, in gear turning, a chuck is typically used to clamp a gear for cylindrical turning operations. However, due to the difference in thickness of the different gears, the height of the gears protruding from the chuck jaws is not certain when the gears are clamped using existing chucks. For an ordinary lathe, after gears with different thicknesses are clamped each time, operators need to spend a great deal of time manually setting the tool to determine a proper machining position, so that the preparation time for machining is increased, the production efficiency is reduced, and the machining precision is easily reduced due to manual misoperation. For a numerical control lathe, although the numerical control lathe has a certain degree of automation, the machining parameters are required to be adjusted again by tool setting, otherwise, the machining quality is affected. Therefore, there is a clear disadvantage in gear turning positioning of the existing chucks, and there is a need for a device capable of quick positioning to solve the above-mentioned problems. Disclosure of utility model The utility model aims to overcome the technical defects, and provides a gear turning quick positioning device which solves the problems in the background technology. In order to achieve the technical aim, the technical scheme of the utility model provides a quick positioning device for gear turning, which comprises a self-centering chuck, wherein a clamping seat is arranged on a clamping jaw seat of the self-centering chuck, an adjustable clamping jaw is arranged at one end of the clamping seat adjacent to the circle center of the self-centering chuck, the adjustable clamping jaw comprises a clamping head and a supporting plate, a telescopic cavity is arranged on one surface of the clamping head connected with the clamping seat, a strip hole penetrating through the clamping head is arranged at the bottom of the telescopic cavity, a connecting column is arranged at one end of the supporting plate, a limiting plate is arranged on one section of the connecting column penetrating through the strip hole, a positioning plate is arranged in the telescopic cavity, a spring is arranged at one surface of the positioning plate adjacent to the clamping seat, and the spring is abutted to the clamping seat and keeps a compression state. Still further, be provided with the locating strip on the adjacent one side of limiting plate and locating plate, be provided with a plurality of constant head tanks with locating strip looks adaptation on the locating plate, a plurality of the constant head tank is along the length direction array in strip hole.
