Description

Technical Field

[0001] The utility model relates to the technical field of drilling and tapping machines, in particular to a drilling and tapping machine used for synchronous pulley production. Background Art

[0002] Synchronous pulleys are generally made of steel, aluminum alloy, cast iron, brass and other materials, and their inner holes are round holes, D-shaped holes, tapered holes and other forms. Synchronous pulley transmission is composed of a closed ring belt with equally spaced teeth on the inner surface and a corresponding pulley. When in motion, the belt teeth mesh with the tooth grooves of the pulley to transmit motion and power. It is a meshing transmission, and thus has various characteristics of gear transmission, chain transmission and flat belt transmission. It is widely used in automobiles, textiles, printing and packaging equipment, sewing equipment, office equipment, laser engraving equipment, tobacco, financial machinery, stage lighting, communications food machinery, medical machinery, steel machinery, petrochemicals, instruments and meters, various precision machine tools and other fields. Synchronous pulleys require drilling and tapping machines during production.

[0003] The existing synchronous pulleys are often produced by drilling first and then tapping. They need to be processed on a drilling machine and a tapping machine respectively. During the processing, the synchronous pulleys need to be repeatedly positioned and fixed to avoid processing errors. Repeated installation and adjustment in the process seriously affects the processing speed of the synchronous pulleys and cannot meet people's usage needs. For this reason, we propose a drilling and tapping machine for synchronous pulley production. Utility Model Content

[0031] The working principle of a drilling and tapping machine for synchronous pulley production provided by the utility model is as follows: when in use, the synchronous pulley can be processed on the workbench 1, and the positioning unit 4 can position the position of the synchronous pulley.

When in use, the synchronous pulley can be put in through the flow ports 54 on both sides, and the processed synchronous pulley can be taken out. When in use, the synchronous pulley can be fixed by the clamp 57. When fixed, the telescopic cylinder 56 can be controlled to extend, and the extension of the telescopic cylinder 56 drives the clamp 57 to close, completing the clamping operation on the target synchronous pulley to prevent it from being displaced during the processing.
