Hobbing machine apparatus with chamfering machine of gear teeth and gear processing method using hobbing machine apparatus

摘要

The present invention relates to a hobbing machine device including a gear chamfer processing machine and a gear processing method using the hobbing machine device. The chamfer processing machine for chamfering the gear teeth is coupled to a station of the hobbing machine device, A material input unit 71 for moving the material to be processed 2 in a horizontal straight line along a horizontal rail in order to continuously perform processing and chamfer processing; The material to be processed (2) moving along the horizontal rail of the material input unit (71) is stopped and moved to the inside of the gear processing unit (83), and the gear processed by the gear processing unit (83) is A material exchange unit 81 that moves to the outside of the study 83; A pair of clippers 51 are provided to pressurize and fix both sides of the material to be processed 2 moved into the gear processing unit 83 through the material exchange unit 81 to allow access of the material to be processed (2). A first station 10 to adjust; The pair of clippers 51 are divided into four stations on the rim side of the rotation shaft 5, and are provided at a position rotated by 90° around the rotation shaft 5 in the first station 10 to process gears. A second station (20) to prepare for it; A third station (30) provided with a hobbing machine for processing the gear teeth (3) on the surface of the material to be processed (2) provided at a position rotated by 90° around the rotation shaft (5) in the second station (20) ; It is provided at a position rotated by 90° about the rotation shaft 5 in the third station 30, and along the edge of the gear 3 processed on the surface of the workpiece 2 through the third station 30 A fourth station 40 equipped with a chamfering device for removing burrs while being moved; The first station 10 is located at a position rotated by 90° around the rotation shaft 5 in the fourth station 40, and the material to be processed 2 from which the burrs are removed from the fourth station 40 is The material to be processed (2) moved to the material exchange unit 81 through the first station 10 and moved to the material exchange unit 81 is discharged in a straight line with the material input unit 71 It characterized in that it is configured to discharge through the portion (75).
