Description

Double-sheet stepless adjusting tool and adjusting method suitable for multiple types of saw blades Technical Field The invention relates to the field of sawing equipment, in particular to a double-piece stepless adjusting tool and an adjusting method suitable for multiple saw blades. Background In the fields of woodworking machinery, metal processing and the like, double-piece sawing equipment (such as a wire saw, a groove saw and the like) is widely used in grooving, cutting and the like. Such devices typically require adjustment of the spacing between the two saw blades to accommodate processing requirements of different widths or depths. At present, a common double-blade saw spacing adjustment mode mainly depends on that gaskets with different thicknesses are additionally arranged or replaced between a saw blade and a rotating shaft. The mode has the following remarkable defects in practical application: 1. the adjustment efficiency is low, the saw blade assembly needs to be disassembled for each adjustment, the gaskets are manually increased and decreased, and the time consumed by single operation often exceeds 10 minutes. In production scenarios requiring frequent replacement of process specifications, frequent downtime adjustments severely affect equipment utilization and production efficiency. 2. The adjustment accuracy is limited and difficult to control, gaskets are usually manufactured with a fixed thickness step (e.g. 0.15 mm) and continuous stepless adjustment of the spacing is not possible. Meanwhile, accumulated errors are easy to generate during superposition and assembly of the multi-layer gaskets, precision deviation caused by manual operation is often more than +/-0.1 mm, width precision of grooving or scribing is directly affected, and high-precision machining requirements are difficult to meet. Therefore, there is an urgent need for a dual-blade saw adjusting tool and method that can achieve rapid, precise, stepless adjustment and has good versatility, so as to overcome the above-mentioned shortcomings in the prior art. Disclosure of Invention The invention aims to solve the technical problems that the conventional double saw blades are required to be disassembled to adjust the distance through a gasket, and the adjustment efficiency is low and the precision is poor, and provides a double-blade stepless adjustment tool and an adjustment method suitable for multiple saw blades. In a first aspect, the invention provides a double-blade stepless adjustment tool suitable for multiple types of saw blades, which comprises a limiting ring, wherein a first saw blade and a second saw blade are sleeved on the limiting ring, the second saw blade is arranged on one side of the first saw blade away from the limiting ring, a first annular groove is formed in one side of the first saw blade facing the second saw blade, an elastic piece is arranged in the first annular groove and is abutted with the second saw blade, the elastic piece is used for providing elastic force for enabling the first saw blade and the second saw blade to be away from each other, and the second saw blade is provided with an adjustment assembly which is connected with the limiting ring and is used for pushing the second saw blade so as to change the distance between the first saw blade and the second saw blade. The invention discloses a double-piece stepless adjusting tool suitable for multiple saw blades, which is characterized in that a first saw blade, an elastic piece and a second saw blade are sleeved in a limiting ring in sequence when the tool is used, the elastic piece is accommodated in a first annular groove, an adjusting component is operated to push the second saw blade to axially move along the limiting ring, so that the distance between the first saw blade and the second saw blade is changed, in the process, the elastic piece provides continuous elastic separating force, stable and continuous adjusting action is ensured, after the distance is adjusted to a target value, the position of the second saw blade is locked through the adjusting component, and quick and accurate stepless adjustment can be completed. Preferably, the elastic piece is a spring piece, the spring piece is arranged in a ring shape matched with the first annular groove, and a notch is arranged on one side of the ring shape. The notch structure provides necessary expansion space for elastic deformation of the spring piece, ensures that the spring piece can generate smooth and continuous linear deformation when being pressed, is a core for realizing high-precision stepless adjustment, and is convenient to assemble and adapt to manufacturing tolerance. Preferably, the adjusting component comprises a plurality of locking screws, the second saw blade is provided with countersunk holes for installing the locking screws, and the limiting ring is provided with fastening screw holes for connecting the locking screws. The structure forms the basis of detach
