Assembly device for automotive air-conditioning fin mold hob

Abstract

The invention discloses an assembling device of an automobile air conditioner fin die hobbing cutter, comprising a bottom plate, a core shaft and a hobbing cutter, wherein the hobbing cutter comprises a flange disc and an annular cutting sheets; the upper end of the bottom plate is fixedly connected with a hobbing cutter fixing base and the hobbing cutter fixing base is fixedly connected with the core shaft; the hobbing cutter is provided with a key slot and the key slot is matched with a rotation stopping pin on the core shaft; a pressure device is arranged at the upper end of the core shaft; the pressure device comprises a plane pressing wheel which is in threaded connection with the core shaft and a steel ball keeping frame which is movably arranged on the core shaft; through grooves are arranged on the plane pressing wheel and the steel ball keeping frame; the positions of the through grooves correspond to the positions of bolt holes on a flange disc of the hobbing cutter; and a plurality of steel balls are arranged between the steel ball keeping frame and the plane pressing wheel. With the adoption of the assembling device, the hobbing cutter can be easily assembled and the time is short; the plane degree can be adjusted within a range of 0.003 mm; and furthermore, all parts of the hobbing cutter are not staggered and a flange is prevented from being deformed.

Description

technical field [0001] The invention relates to an assembly device, in particular to an assembly device for an automobile air-conditioning fin mold hob. Background technique [0002] At present, the automotive air-conditioning fin mold hob includes upper and lower flanges and ring cutting blades. Its assembly is usually clamped by flat pliers, and then directly tightened with a hexagonal wrench. There are two problems in this assembly method: [0003] 1. The clamping force of the flat pliers is heavy load, which will cause the deformation of the flange of the hob. After testing, the deformation of the flange will be about 0.02-0.05mm; [0004] 2. The six inner corner screws used for assembly are all right-handed. During the tightening process, the upper and lower flanges and the ring cutting blades will be misaligned. Deep inconsistency will seriously affect the service life of the hob. Contents of the invention [0005] The object of the present invention is to solve th...
