A multi-angle processing jig for bone plate

Abstract

The invention discloses a multi-angle machining clamp for a bone fracture plate. The multi-angle machining clamp comprises a base. A sliding groove is formed in the middle portion of the base, and T-shaped grooves are formed in the two sides of the sliding groove. Lead screw bases are arranged at the two ends of the base and internally provided with lead screws. A T-shaped base is arranged at oneend of the base, and a sliding base is arranged at the other end of the base. Locking bolts are arranged at the two ends of the sliding base. Each locking bolt is provided with a first nut. The upperend of the sliding base and the upper end of the T-shaped base are in cup joint with first fixing rods. Four positioning holes are evenly distributed in the middle portion of each first fixing rod along the circumference. The sliding base and the T-shaped base are provided with fixing pins. A first screw is arranged at one end of each first fixing rod and provided with a second nut, a stand columnis arranged at the other end of each first fixing rod, a rectangular hole is formed in the upper end of each stand column, a rotation rod is arranged at the upper end of each rectangular hole, and apressing block is arranged at the bottom of each rotation rod. A second fixing rod is arranged at the lower end of each stand column, a second screw is arranged at the front end of each second fixingrod, each second fixing rod is in cup joint with a limiting block, and each second screw is provided with a third nut. The clamp manufacturing cost is relatively low, and the clamp has the beneficialeffects of being high in positioning precision, resistant to abrasion, convenient to use and the like.

Description

technical field [0001] The invention relates to the field of medical device processing, in particular to a multi-angle processing jig for bone plates. Background technique [0002] The processing device of the previous three-axis machining center can only process workpieces with a single angle. When using machining, it cannot process workpieces with large-angle curved surfaces. The limitations are large. For example, the main processes of straight bone plate processing include hole processing and end surface processing. , In actual processing, multiple fixtures are usually required to complete the processing of the bone plate, and the manufacturing cost of the fixture is high, and the processing efficiency is low. Now there is a need for a fixture that is easy to operate and convenient to process all angles of the bone plate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-angle processing jig for bone pl...

When using machining, it cannot process workpieces with large-angle curved surfaces. The limitations are large. For example, the main processes of straight bone plate processing include hole processing and end surface processing. , In actual processing, multiple fixtures are usually required and clamped multiple times to complete the processing of the bone plate. The manufacturing cost of the fixture is high and the processing efficiency is low. Now there is a need for a fixture that is easy to operate and convenient to process all angles of the bone plate
