Assembling device of automobile air conditioner fin die hobbing cutter

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 of an automobile air-conditioning fin die hob. Background technique [0002] At present, automotive air-conditioning fin mold hob includes upper and lower flanges and a ring cutting blade. The assembly is usually held by flat-nose pliers, and then the screw is directly tightened with a hexagonal wrench. There are two problems in this assembly method: [0003] 1. The flat-nose pliers are heavy-load clamping force, which will cause the deformation of the hob flange. After testing, the flange will be deformed by about 0.02-0.05mm; [0004] 2. The six inner corner screws used for assembly are all in the right-handed direction. During the tightening process, the upper and lower flanges and the ring cutting blades will be dislocated. Once the dislocation is performed, the produced fins will be corrugated and deformed, and the upper and lower blades will be cut. Deep inconsisten...
