Problems solved by technology

[0007] However, in the gear grinder disclosed in Patent Document 1, only one dressing device is provided, and it is necessary to replace the dressing device for each type of workpiece.
Therefore, it takes time to replace the dressing device, and it is almost impossible to improve the productivity of the helical gear
In addition, in the above-mentioned Patent Document 2, there is no research on the trimming device.

Embodiment

[0037] Hereinafter, embodiments of a rotary processing machine and a processing method thereof will be described with reference to the drawings.

[0038] The rotary processing machine 1 of this example is as figure 1 , figure 2 As shown, it is equipped with: a rotating device 2 that supports and rotates a workpiece 8 formed with a helical tooth 81; A processing device 3 for machining, and a transfer device 4 for loading and unloading a workpiece 8 to and from the rotary device 2 .

[0039] The conveyance device 4 has a plurality of clamp claws 51 for clamping the workpiece 8 and a dresser 52 for shaping the grinding teeth 71 around the rotation center axis 401 . The conveying device 4 is configured to rotate around the rotation center axis 401 to sequentially bring the gripper claws 51 closer to the rotary device 2 and to make the respective dressers 52 closer to the machining device 3 sequentially. Such as image 3 As shown, the dressing teeth 522 of the respective dress...

Abstract

A rotary machining device (1) provided with a rotation device (2) for supporting a workpiece on which helical teeth are formed and causing the workpiece to rotate, a machining device (3) for using grinding teeth (71) of a rotary grindstone (7) to grind the helical teeth of the workpiece caused to rotate by the rotation device (2), and a transportation device (4) for loading and unloading the workpiece (8) to and from the rotation device (2). The transportation device (4) has a plurality of grippers (51) for holding the workpiece and dressers (52) for molding the grinding teeth (71). The transportation device (4) turns about a turn center axis (401), causes the grippers (51) to sequentially move nearer the rotation device (2), and causes the dressers (52) to sequentially move nearer the machining device (3). The dress teeth of the dressers (52) have tooth surfaces that are differently shaped from each other.

Description

technical field [0001] The present invention relates to a rotary processing machine provided with a processing device for grinding a rotating workpiece with a rotating grindstone, and to a processing method thereof. Background technique [0002] In a rotary processing machine in which a workpiece rotated by a rotary device is ground by a rotary grindstone of the processing device, the shape of the rotary grindstone is appropriately shaped using a dresser according to the type of workpiece to be processed. For example, for a rotary grinding wheel that grinds the helical teeth of a workpiece, prepare a wheel dresser for each type of workpiece, and adjust the pressure angle of the grinding wheel tooth surface of the rotary grinding wheel and the fillet of the tooth profile (from the root to the top of the tooth) curved dilated shape). [0003] For example, Patent Document 1 discloses a gear grinding machine in which a table for holding and rotating a workpiece, a sub-column fo...
