Problems solved by technology

If the saw blade is too loose, the saw blade will be twisted, the saw kerf will be skewed, and the saw blade will be easily broken;
[0005] (2) It is inconvenient to adjust the angle of the saw blade
When sawing, it is often necessary to adjust different angles according to the structure of the workpiece, but the existing bow structure can only be adjusted to 0 degrees or 90 degrees. When the workpiece is in a place with poor conditions, sawing is very inconvenient, and it needs Dismantling the saw blade and the square mortise at both ends, and reinstalling, is time-consuming and labor-intensive, reducing work efficiency

Abstract

The invention discloses a 360-degree constant-value torsion saw bow which comprises a constant-value torsion device, a first movable pull rod, a first fixed pull rod, a second fixed pull rod, a saw bow handle, a ratchet wheel device, a saw blade and a second movable pull rod. The ratchet wheel device comprises a front cover, a rear cover, a ratchet wheel and a pawl, and the front cover and the rear cover are fixedly connected with the second fixed pull rod. The constant-value torsion device comprises a movable sleeve and a jacking sleeve. The saw blade can be controlled within a reasonable tightness range by easily adjusting the torsion. Unnecessary damage to the saw blade caused by uncomfortable tightness is reduced to a great extent, unnecessary fund consumption of the saw blade in the aspect is also reduced, angle conversion can be achieved only by slightly pulling the movable swing rod, and the original replacement time is saved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a 360° constant-value torque saw bow. Background technique [0002] Fitter is a very important type of work in machining. With the rapid development of my country's equipment manufacturing industry and the wide application of high-end precision manufacturing technology, the position of fitters in the manufacturing industry is also getting higher and higher due to the advantages of flexible processing, parts with complex shapes and high precision, and small investment. . Sawing processing is one of the basic skills of fitters. The quality and speed of sawing directly affect the subsequent processing and quality of products. [0003] The sawing tool is a saw bow, and the existing saw bow has the following disadvantages: [0004] (1) It is inconvenient to adjust the tightness of the saw blade. The saw blade is fixed by a fixed chuck at the far end and a movable chuc...
