Description

A woodworking circular saw transmission mechanism

technical field

The utility model relates to a woodworking sawing machine, in particular to a woodworking circular saw transmission mechanism.

Background technique

Circular sawing machine uses a disc-shaped saw blade as a sawing tool, and performs continuous rotary motion around the shaft to saw wood. Traditional woodworking circular sawing machines, when sawing wood, often have two discs. The saw blades are on the same shaft, causing the two circular saw blades to rotate simultaneously, which brings safety hazards to the operator when a single person works.

Contents of the invention

In order to overcome the potential safety hazard brought by the rotation of the other saw blade to the operator when the existing woodworking circular sawing machine is working alone, the utility model provides a woodworking circular saw transmission mechanism, which can not only make the disc When the sawing machine is working by a single person, one of the saw blades stops rotating, and the other saw blade continues to rotate. When two people work, the two saw blades can rotate at the same time to complete different processes.

The technical scheme of the utility model: a woodworking circular saw transmission mechanism, including an operating table and a gear box arranged on the operating table, and an input shaft connected to the motor through a V-belt transmission is arranged on one side of the gear box. The input shaft is provided with a double sliding gear consisting of a first sliding gear and a second sliding gear, and two first output shafts and a second parallel to the input shaft are respectively provided on the other side of the gearbox. The output shaft is provided with a first output gear at one end of the first output shaft, and its other end is connected with the first main shaft on the large saw blade through a first coupling, and a second output gear is provided at one end of the second output shaft , the other end of which is connected to the second main shaft on the small saw blade through a second coupling, the first sliding gear is meshed with the first output gear at the end of the first output shaft, and the second sliding gear is in contact with the The second output gear at the end of the second output shaft meshes.

After the double sliding gear slides to the left, the first sliding gear on the input shaft meshes with the first output gear at the end of the first output shaft, and the second sliding gear on the input shaft meshes with the second output gear. The second output gear at the end of the shaft is disengaged.

After the double sliding gear slides to the right, the first sliding gear on the input shaft is separated from the first output gear at the end of the first output shaft, and the second sliding gear on the input shaft is separated from the second output gear. The second output gear at the end of the shaft meshes.

Due to the adoption of the above-mentioned technical scheme, the utility model has the advantages that: when the utility model is operated by a single person, one of the saw blades can be stopped from rotating, and the other saw blade can be rotated independently; The saw blades rotate at the same time, which not only meets the different use requirements of people, but also reduces potential safety hazards while improving work efficiency.
