1、 Preparation work

Firstly, it is necessary to determine the relative position between the left and right tool holders of the gear hobbing machine and the cutting tool shaft. After confirmation, it is necessary to tighten the cutting tool holder seat plate to avoid affecting the tool alignment due to shaking

2. Confirm whether the anti tilting measures of the cutterhead and ball screw are effective to ensure the stability of the entire system during the fine-tuning process.

2、 Knife alignment operation

1. Coarse adjustment process

Place the cutting tool onto the tool holder, loosen the positioning wrench, and let the cutting tool hang naturally. Then adjust the height of the tool holder to match the height of the workpiece. After adjustment, move the positioning rod to the left, position the knife holder on the positioning table, and press it firmly. Then you can proceed with coarse adjustments.

During rough adjustment, manual or automatic feeding devices should be used to push the gear and gear cutter to mask. The tool holder should be manually controlled to move the handle left and right, and the minimum distance between the cutting tool blade and the short axis of the workpiece should be adjusted to ensure the perfection of the mask. A tooth is a cutting surface, so when adjusting, make sure that the cutting surface matches the tooth and the blade is parallel to the cutting surface.

When the motor rotates, the irregularity of the cutting tool surface can be observed. At this time, the tool surface and teeth can be adjusted.

2. Fine adjustment

After the rough adjustment is completed, further fine adjustments are needed. When the gear is clamped by the lathe, it can be placed in the fixture that matches the machine tool, and the centerline of the workpiece can be aligned with the centerline of the tool holder. The reverse cam can be rotated, and the fine adjustment distance of the entire system can be determined by visual inspection and hand touch.

Rotate the cam to the end, control the fine adjustment distance of the teeth, adjust the pitch and depth of the gears to achieve the optimal state of rough adjustment and gear masking.

3、 Precautions

When operating the gear insertion machine, pay attention to safety and wear work clothes and safety helmets.

When setting the knife, rough adjustments should be made first to ensure perfect masking, and then further fine adjustments should be made.

During the operation, it is important to closely observe the status of the sample and the condition of the subsequent gears in order to make timely adjustments.

The above are the operating steps and precautions for the tool alignment of the gear hobbing machine, hoping to provide assistance to beginners.
