Hobbing cutter and method for processing shaver by using said hobbing cutter

Abstract

The present invention provides a hobbing cutter, which has a plurality of cutting teeth, and the cutting teeth further have: a first tooth part, which can form a first involute profile on a workpiece, and a second The tooth portion can form a curved profile on the workpiece. Using the gear hobbing cutter, the present invention further provides a method for forming a gear skiving cutter, which includes the following steps: setting two first involute paths interlaced at a designated position on a body to be processed and a curved profile; making the rotational axis of the hobbing cutter form an included angle with the rotational axis of the body to be processed; and causing the hobbing cutter to hob the body to be processed along a cutting path, A gear skiving blade having a first involute profile and an escape area profile is formed by the first and second tooth portions.

Description

technical field [0001] The present invention relates to a gear hobbing cutter and a method for forming a gear skiving cutter, in particular to a gear hobbing cutter formed by cutting teeth with two different profile configurations and using the gear hobbing cutter to process a gear with an involute A gear hobbing cutter in the escape area of ​​the skiving tooth and the root of the skiving tooth and a method for processing the skiving knife by using the hobbing knife. Background technique [0002] The traditional cutting of gears is to cut the tooth shape by the movement of the workpiece and the tool. First, the hobbing cutter with the worm shape is used as a semi-finishing cutter, and then the gear is finished with a gear-shaped scraping cutter. Please refer to figure 1 As shown, the figure shows the appearance of a traditional gear scraping knife. The gear skiving knife 10 has a disc-shaped body 11, and scraper teeth 12 are arranged on the outer periphery of the body 11. Th...

Problems solved by technology

[0004] 1. The diameter d1 of the drill hole 131 is greater than the root distance d2 of the scraper teeth 12, so that the scraper teeth 12 form a thinner neck 122. The existence of the neck 122 reduces the strength of the scraper teeth 12, and the neck 122 is easy to cause fracture

[0005] 2. After the main body 11 has been drilled and moved to the gear hobbing machine, it must be aligned before the gear can be hobbed accurately, which is labor-intensive and time-consuming

[0006] 3. Drilling machine and gear hobbing machine must be installed, the equipment cost is high and takes up space

[0007] 4. The main body 11 is bulky and heavy. It is extremely inconvenient to move up and down between the drilling machine and the gear hobbing machine. It consumes manpower and man-hours, and it is easy to damage the main body due to collision.

However image 3 In the existing technology, the gear skiving cutter mainly utilizes two gear hobbing processes to achieve the tooth profiles forming two different curves 141, 142, but such a process is time-consuming in the processing procedure, and virtually increases the production cost and manpower.
