Description

Technical Field

[0001] The utility model relates to the technical field of grooving machines, and particularly relates to a grooving machine for producing thread tools. Background Technique

[0002] A thread tool is a rotary tool with one or more cutting teeth used for milling. When processing a thread tool, several grooves need to be opened on the outer side of the thread tool to guide the waste after cutting. In the prior art, when processing the grooves on the outer side of the thread tool, a three-jaw chuck is usually used to clamp the thread tool. During the clamping process, an operator needs to hold the thread tool with one hand and adjust the clamping gap of the three-jaw chuck with the other hand. During the process of holding the thread tool, the hand shakes, which may cause the thread tool to collide with the side of the chuck, affecting the accuracy of the chuck. Secondly, when it is necessary to change the position for processing, the workpiece needs to be taken out of the chuck, and then the direction of the thread tool is rotated to change the position for re-grooving. The efficiency is low, and the iron chips after processing will remain on the chuck, which is inconvenient to clean. Therefore, a grooving machine for producing thread tools is proposed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a grooving machine for producing thread tools to solve the problems of the grooving machine for producing thread tools.

[0004] The utility model specifically adopts the following technical solutions to achieve the above purpose:

A rotary cleaning structure is arranged on the side surface of the first connecting block.

[0006] Furthermore, the auxiliary clamping structure includes a first connecting cylinder fixedly connected to the end surface of the three-jaw chuck.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, the threading tool to be grooved is inserted into the interior of the three-jaw chuck. After the threading tool comes into contact with the auxiliary clamping structure, the threading tool is initially fixed at the central position of the three-jaw chuck. Then, the three-jaw chuck is used to lock the threading tool, avoiding the collision between the hand-held threading tool and the chuck during the clamping process, which may cause wear to the chuck and affect the accuracy of the chuck. Initially, the three-jaw chuck is fixed by the tensioning structure. The threading tool is grooved by the rotating grooving drill bit. After the first grooving is completed, the constraint on the three-jaw chuck by the tensioning structure is released. After rotating the three-jaw chuck to a suitable position, the tensioning structure is started again, and then the threading tool is grooved by the grooving drill bit, which facilitates grooving the threading tool multiple times and improves the processing efficiency. After processing, the iron filings inside the auxiliary clamping structure and the three-jaw chuck are cleaned by the rotary cleaning structure. Description of the Drawings
