Description

Technical Field

[0001] The utility model relates to the technical field of saw blade devices, in particular to an integrated saw blade arbor. Background Art

[0002] Saw blades are a general term for thin circular cutting tools used to cut solid materials. Saw blades can be divided into: diamond saw blades for stone cutting; high-speed steel saw blades for metal cutting; carbide saw blades for cutting solid wood, furniture, artificial boards, aluminum alloys, aluminum profiles, radiators, plastics, plastic steel, etc.

[0003] There is an inseparable relationship between the saw blade and the saw blade arbor, and the saw blade arbor assembly is usually used on processing machine tools.

[0004] The existing Chinese patent application number is: CN202222918779.8, and is named: A new type of adjustable multi-saw blade arbor assembly, in which the fixing mechanism, the fixing ring and the fixing block are used in combination to adjust the number of saw blade bodies installed on the arbor body, thereby improving the use range of the device, and the fixing rings of different sizes can be replaced to adjust the distance between the two groups of saw blade bodies, and the saw blade bodies can be quickly fixed to the arbor body through the provided fixing blocks and threads. The entire device has a simple structure, which increases the practicality of the entire multi-saw blade arbor assembly, and also overcomes the problem that the multi-saw blade knives that can simultaneously process multiple grooves proposed in the background technology are inconvenient to disassemble and assemble, and the number of saw blades cannot be increased or decreased according to actual usage conditions, and the cutting head and saw blade are integrated. When the cutting head is damaged, the cutting head cannot be replaced separately, resulting in a certain waste of resources.

[0005] However, when this structure is in use, the arbor body and the saw blade are connected and fixed by a threaded structure. However, when in use, since the external transmission structure also rotates in a rotating manner, it is easy to get stuck or disengaged when the main structure is replaced, which is not convenient for replacing saw blades of different sizes and is not conducive to the rapid disassembly and assembly of single or multiple groups of saw blades. Utility Model Content

[0006] Technical problems solved

[0007] In view of the above-mentioned shortcomings of the prior art, the present invention provides an integrated saw blade arbor, which is connected in combination by a drill shank body structure and a nut structure. The device can be connected and fixed to the external structure through the nut structure, and the bottom saw blade is fixed to the outside of the threaded head through a gasket, and the gasket is clamped to the bottom end of the drill shank body and the outside of the threaded head through a locking nut. The nut adopts an ER11 nut structure, which has a high concentricity with the external structure and a strong structural rigidity. Due to the structural mode of the threaded head, the gasket-saw blade and the locking nut can be quickly aligned, saving tool changing time. To improve work efficiency, the bottom end of the drill shank body is trumpet-shaped with a small outside and a large inside, which is convenient for transmission and fixed connection with external power equipment to realize power transmission, and the nut can be tightened with the external equipment, and the inner side of the equipment can contact the outer side wall of the drill shank body to realize power transmission.
