Description

Technical Field

[0001] The utility model relates to the technical field of outer cylindrical surface turning and positioning, in particular to an outer cylindrical surface turning and positioning tool for upper and lower shafts. Background Art

[0002] The shaft is a cylindrical object that passes through the middle of the bearing, the middle of the wheel, or the middle of the gear, but a small part is square. The shaft is a mechanical part that supports the rotating parts and rotates with them to transmit motion, torque or bending moment. It is generally in the shape of a metal round rod, and each section can have a different diameter. The parts that rotate in the machine are installed on the shaft. Turning is lathe processing, which is a part of mechanical processing. It mainly uses a turning tool to turn the rotating workpiece.

[0003] The existing turning positioning tooling only clamps and positions the two side ends of the shaft and then processes it. This positioning method easily causes the shaft to produce relative displacement under the action of gravity, and the processing accuracy of the shaft cannot be guaranteed. If the shaft is too large and too heavy, manual removal of the shaft may not only cause the shaft to fall accidentally, but also consume too much manual labor, reducing the applicability of the device. Therefore, the existing device needs to be improved to meet actual needs. Utility Model Content
