Full-automatic medical grinding device used for kirschner wires in orthopedics department

Abstract

The invention relates to a full-automatic medical grinding device used for kirschner wires in the medical orthopedics department. A feeding module, a grinding wheel module, a material clamping moduleand a discharge module are orderly arranged on a fixed base. A CCD industrial camera is arranged between the grinding wheel module and the material clamping module. The structure of a conventional standardized high-precision CNC grinding machine is abandoned. When the requirement of machining precision for kirschner wires is met, manufacture cost of the device is reduced as much as possible. Meanwhile, the feeding assembly replaces conventional manual replacement and feeding so that intensity of manual operation is evidently reduced. A conventional clamp is replaced by the adjustable grindingwheel module, thereby increasing production efficiency. Production capacity is improved while manufacture cost is lowered.

Description

technical field [0001] The invention relates to the technical field of grinding machines, in particular to a fully automatic Kirschner wire grinding device for medical orthopedics. Background technique [0002] In the known technical field, Kirschner wire is a commonly used internal fixation material in orthopedics. It is used to fix small fractures or avulsion fractures and other fractures with low stress. It is also used to fix temporary fracture fragments in orthopedics. Its structure is mainly a pointed shape composed of multiple conical surfaces. In the existing production, it is necessary to grind the cylindrical needle workpiece, and generally at least four surfaces need to be ground. [0003] The existing technology is to use a special high-precision CNC grinding machine, with a special fixture, each time a surface is ground, and the position is rotated once. In fact, the dimensional accuracy of the Kirschner wire is far from the dimensional accuracy of the tradition...

AI Technical Summary

Problems solved by technology

[0003] The existing technology is to use a special high-precision CNC grinding machine, with a special fixture, each time a surface is ground, and the position is rotated once. In fact, the dimensional accuracy of the Kirschner wire is far from the dimensional accuracy of the traditional mechanical connector, but it still needs Guarantee a certain accuracy and complete one-time processing, so the existing production can only use high-precision CNC grinding machines instead of ordinary roughing grinding machines

This not only significantly increases manufacturing costs, is not conducive to expanding production capacity and reducing surgical costs, but is also a great waste of resources

Moreover, manual loading and unloading is generally used in existing production. Due to the large demand for products, the actions that need to be operated are also relatively cumbersome and labor-intensive.
