Description

Gear transmission concentric positioning device

Technical Field

The utility model belongs to the technical field of stamping die manufacturing, and particularly relates to a gear transmission concentric positioning device.

Background

The press working is a press working method for obtaining a desired part by applying pressure to a material at room temperature using a die mounted on a press to cause separation or plastic deformation thereof; the stamping process directly works by a die, the die comprises a punch and a bottom die, the stamping die is special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping process, the special process equipment is called cold stamping die (commonly called cold stamping die), the stamping die cannot work independently, and an equipment workbench for supporting, connecting and positioning the die is needed.

Because the size and the diameter of different stamping parts are different, when the cylindrical workpiece is stamped on the workbench, the circle center of the bottom surface of the workpiece needs to be searched, so that the placement position of the workpiece is coaxial and concentric with the punch, and the stamping quality of the stamping parts is ensured.

The prior patent CN202020606300.5 discloses an adjustable stamping equipment workbench, wherein a hexagonal plate drives a stamping head to rotate to the top surface of the workbench, and meanwhile, the hexagonal plate drives a driving bevel gear to rotate through a horizontal rotating shaft, and finally drives a stamping chassis to rotate through a vertical rotating shaft, so that the stamping head and a stamping hole rotate at the same angle; however, the workpiece size that can be matched by the workbench is still limited, and the workbench cannot be guaranteed to adapt to all workpiece diameters, so that different punched holes need to be replaced.
