Grass-cutting hob, cutter welding tool of grass-cutting hob and manufacturing method of grass-cutting hob

Abstract

The invention discloses a grass-cutting hob, a cutter welding tool of the grass-cutting hob and a manufacturing method of the grass-cutting hob, and belongs to the field of lawn machines and manufacturing processes of the lawn machines. By means of the grass-cutting hob, the cutter welding tool and the manufacturing method, the problem that existing grass-cutting hob manufacturing methods are high in cost or poor in quality is solved. The grass-cutting hob comprises cutters. Multiple insertion grooves are formed in each cutter. The corresponding insertion grooves are formed in each cutter with the circle center of the surface of the cutter as the central point according to an array with the angles between items being a. Positioning holes are formed in the cutters. The cutter welding tool of the grass-cutting hob comprises a base and multiple supporting plates perpendicularly arranged on the base at equal intervals. A cutter positioning block is arranged on one side of each supporting plate. The cutter positioning blocks correspond to the positioning holes. The manufacturing method of the grass-cutting hob mainly includes the step that the cutters are welded through the combination of the improvement mentioned above. The grass-cutting hob, the cutter welding tool and the manufacturing method mainly have the beneficial effect that on the premise of not increasing the production cost, the production efficiency and the quality of the grass-cutting hob are improved.

Description

technical field [0001] The invention belongs to the field of lawn machinery and its manufacturing technology, and in particular relates to a grass mowing hob and its cutterhead welding tooling and manufacturing method.
