Clamping device for automatic helmet drilling machine

Abstract

The invention discloses a clamping device for an automatic helmet drilling machine, and relates to the technical field of helmet machining equipment. The clamping device comprises a workbench, the workbench is of a circular structure, and a plurality of radial clamping mechanisms are arranged on the workbench; each clamping mechanism comprises a sliding rail fixed to the workbench, and two sliding seats are arranged on the sliding rails in a sliding mode; flexible clamps are arranged on the sliding seats; the clamping mechanism further comprises a first threaded rod and a second threaded rod which are rotatably matched with the workbench; the first threaded rod and the second threaded rod are in threaded fit with the two sliding seats correspondingly; transmission gears meshed with each other are arranged at the ends, away from the axis of the workbench, of the first threaded rod and the second threaded rod correspondingly; and a driven bevel gear is arranged at the end, close to the axis of the workbench, of the first threaded rod. The clamping device for the automatic helmet drilling machine provided by the invention is high in clamping precision and convenient to use.

Description

technical field [0001] The invention relates to the technical field of helmet processing equipment, in particular to a clamping device for a helmet automatic drilling machine. Background technique [0002] The racing helmet is a kind of sports protective gear that protects the athlete's head from injury in motorsports. The racing helmet is composed of the main body of the helmet, the goggles on the helmet, the inner lining of the helmet and other accessories. These accessories are installed on the helmet. When putting it on, you first need to drill holes in the helmet body, and then you can install accessories. [0003] The structure of the existing helmet automatic drilling machine is similar to the structure of a five-axis milling machine whose publication number is CN104668637A. The five-axis milling machine includes a base, a sliding table and a workpiece table. Three first slide rails are arranged in parallel in the lateral direction, and the slide table is slidably ar...

AI Technical Summary

Problems solved by technology

The picture is a schematic diagram of the structure of an existing helmet finished product and blank. There are irregular surplus materials in the lower part of the helmet blank. Since holes need to be drilled on the main body of the helmet, only the lower part of the helmet can be clamped. The remaining material of the blank causes great difficulties in the clamping of the fixture

The existing fixture is difficult to accurately clamp the blank of the helmet, which often causes deviations in the processing position of the helmet, and the helmet automatic drilling machine cannot automatically identify and adjust, resulting in deviation of the hole position after drilling. As a result, accessories cannot be installed, resulting in more scrap products and seriously affecting production
