Description

Technical Field

[0001] The invention relates to the field of saw blades, and in particular to a high-precision saw blade quick installation structure. Background Art

[0002] Saw blades are a general term for thin circular tools used to cut solid materials. According to different applications, saw blades can be divided into: milling saw blades, machine saw blades, manual saw blades, metal-specific saw blades (aluminum saw blades, copper saw blades, stainless steel saw blades, etc.), pipe cutting circular saw blades, wood saw blades, stone saw blades, acrylic saw blades, etc. According to different material classifications, they can be divided into: high-speed steel saw blades (HSS saw blades), welded alloy saw blades, toothed alloy saw blades, diamond saw blades, etc.

[0003] There are many types of circular saw blades according to their materials, models, and specifications. In recent decades, circular saw blades have derived a variety of improved structures. However, in the process of production practice, there are still some technical problems of circular saw blades that have not been well solved. For example, there are the following two situations in the use of circular saw blades. First, the saw machine shaft corresponding to the center hole of the circular saw blade will wear and become thinner during long-term use, and the difference between the center hole diameter and the cross-sectional diameter of the saw machine shaft will increase; second, in the process of installing the circular saw blade on the saw machine shaft, due to factors such as gravity, installation technology, and lifting equipment limitations, the center hole of the circular saw blade and the axis of the saw machine shaft cannot completely coincide. The above two factors act separately or together, causing the circular saw blade to be in an eccentric position, which in turn causes different cutting depths of the workpiece at different positions of the circular saw blade during the next cutting operation, causing the part of the circular saw blade that cuts the deepest on the workpiece to wear the fastest, which in turn causes uneven wear of the saw teeth at different positions on the circular saw blade, and may even easily lead to local damage, ultimately significantly affecting the service life of the circular saw blade and increasing the cost of using the circular saw blade. This is also a technical problem that urgently needs to be improved in this field.

[0004] In response to the above problems, the applicant disclosed a saw blade with an adjustable center hole in patent document CN202010792055.6. It includes a saw blade body, wherein deformation seams are evenly distributed near the center hole of the saw blade body, and the portion of the saw blade body near the center hole is divided into evenly distributed deformation petals by the deformation seams, and each deformation petal is provided with a deformation auxiliary hole, and the deformation auxiliary holes are evenly distributed around the periphery of the center hole, and a circle of mounting holes is evenly distributed around the periphery of the deformation petal. The deformation petal deforms under the action of external force and moves toward the space at the deformation seam. This device can overcome the problem of local accelerated wear and damage caused by deformation of the center hole of the circular saw blade after long-term use and eccentric installation of the circular saw blade, thereby significantly improving the service life of the saw blade. The frequency of replacement and maintenance of the saw blade is reduced, and the production cost is significantly reduced.

[0005] Although the above-mentioned saw blade can solve the problems of poor precision and low life caused by wear, it is found that its installation is extremely inconvenient during use. It requires the use of special tools for circumferential tightening and installation, and disassembly and assembly is time-consuming and labor-intensive. Therefore, there is an urgent need for a high-precision saw blade quick installation structure that can improve the above-mentioned problems. Summary of the invention
