Description

Technical Field

[0001] This utility model relates to the field of saw blade locking technology, and more specifically, to a woodworking saw blade locking structure. Background Technology

[0002] A saw blade is a tool used to cut objects. There are many types of saw blades, such as strip saw blades and circular saw blades. Circular saw blades are usually used when cutting boards. Existing circular saw blades include a saw blade body that is roughly circular in shape. The periphery of the saw blade body has several sets of cutting units arranged in a circular array. The cutting unit includes saw teeth, saw tooth backs, and chip grooves. When cutting boards, the upper end face of the saw teeth is mainly used for cutting.

[0003] Existing woodworking saw blade locking structures, in order to ensure stable operation and prevent saw blade detachment, involve complex lock-bone designs. This results in slow saw blade replacement and installation. Furthermore, when the saw blade becomes stuck and generates stress, if rotation is not stopped, the blade will continue to rotate. The combined effect of external load and residual stress can lead to saw blade breakage and ejection, posing a safety hazard to workers. Therefore, a new woodworking saw blade locking structure is proposed to address these issues. Utility Model Content

[0004] To overcome the aforementioned defects of the prior art, the embodiments of this utility model provide a woodworking saw blade locking structure. The technical problem to be solved by this utility model is that the existing woodworking saw blade locking structure has a relatively complex design to ensure stable operation and prevent the saw blade from falling off. This results in a slow speed when replacing and installing the saw blade. Furthermore, when the saw blade is stuck and generates stress, if it continues to rotate, the external load and residual stress will combine to cause the saw blade to break and fly away, which will affect the safety of the workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a woodworking saw blade locking structure, including a support component, a locking component on one side of the support component, and a connecting component on the other side of the support component;

[0006] The support assembly includes a base plate, a support column fixedly connected to the top of the base plate, a rotating groove formed on the surface of the support column, a rotating column arranged inside the rotating groove, a side column one fixedly connected to one end of the rotating column, a side column two fixedly connected to the other end of the rotating column, a plurality of buffer pads fixedly connected to the surface of the side column two away from the rotating column, a positioning column fixedly connected to the surface of each buffer pad, a central column fixedly connected to the side column two near the positioning column, and a locking hole formed at one end of the central column.

[0007] In a preferred embodiment, the locking assembly includes a saw blade with multiple positioning holes 1 through its surface and a through hole 1 through its center. A locking disc 1 is provided on one side of the saw blade, and a locking disc 2 is provided on the other side of the saw blade. Both locking disc 1 and locking disc 2 have multiple positioning holes 2 on their surfaces and a through hole 2 at the center of their surfaces. A locking cover is provided on the side of locking disc 1 away from the saw blade. A locking opening is provided on the outer surface of the locking cover, and a locking bolt is rotatably connected to the inner cavity of the locking opening. Multiple protrusions are fixedly connected to the outer surfaces of both locking disc 1 and locking disc 2.

[0008] In a preferred embodiment, the connecting assembly includes a first connecting plate, a cross post fixedly connected to one side surface of the first connecting plate, a cross arc plate fixedly connected to the side surface of the cross post away from the first connecting plate, a plurality of arc-shaped locking posts provided on the outer surface of the cross post, and a second connecting plate fixedly connected to the side of the arc-shaped locking posts away from the first connecting plate.

[0009] In a preferred embodiment, the inner diameter of the buffer pad is the same as that of positioning hole one and positioning hole two, the inner diameter of the central column is the same as that of through hole one and through hole two, and the outer side of side column one is fixedly connected to connecting plate one; in later use, the side column one is rotated by connecting plate one to achieve the rotation effect.

[0010] In a preferred embodiment, the lock cover has a threaded opening on the side away from the lock opening, which engages with the surface of the central column. The convex strip has an arc-shaped design, and the direction of the arc is opposite to the direction of the saw blade teeth. In later use, the connection between the lock cover and the central column is first achieved through the connection between the lock hole and the bolt, ensuring the stability of the saw blade operation. Because the convex strip is opposite to the direction of the saw blade teeth, it can drive the sawdust outward when the saw blade is grinding the wood, preventing the sawdust from entering the equipment and ensuring the cleanliness of the equipment connection area.

[0011] In a preferred embodiment, the outer surface of the arc-shaped locking post is also arc-shaped, and the area of ​​the cross post near the connecting plate is larger than that of the cross arc plate. The connecting plate is connected to an external motor. During later use, when the saw blade gets stuck and generates stress, since the intersection of the arc-shaped locking post, the cross post, and the cross arc plate are all arc surfaces, the arc-shaped locking post can hold the cross arc plate and the cross post to rotate when there is no stress obstruction. When stress is generated, the arc-shaped locking post will detach from the cross arc plate and the cross post due to the arc surface, stopping the cross arc plate and the cross post from driving the saw blade to rotate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This utility model, by providing a support component and a locking component, allows for the connection of the rotating column, positioning column, and central column within the support component with the locking disc 2, locking disc 1, saw blade surface, and locking cover of the locking component. After the locking cover is directly rotatably connected to the central column, it is then connected to the locking hole via a bolt. This double-layer locking method makes disassembly and assembly more convenient and improves efficiency without reducing the rotational stability of the saw blade.

[0014] This utility model, by incorporating a support assembly, a locking assembly, and a connecting assembly, addresses the issue of saw blade breakage and potential safety hazards when the saw blade becomes stuck in the wood during later use. Normally, the saw blade is already under stress, and continued rotation could lead to breakage and even endanger nearby personnel. In this situation, the locking assembly, locking disc two, locking disc one, the saw blade surface, and the lock cover are all driven to rotate via the connecting assembly. When the saw blade becomes stuck and under stress, the curved locking pin, along with the cross pin and the cross plate, forms an arc surface. When no stress obstructs the movement, the curved locking pin engages with the cross plate and cross pin, preventing them from rotating the saw blade and thus avoiding the risk of breakage and potential safety hazards to workers. This significantly improves safety during use. Attached Figure Description

A locking hole 110 is opened at one end of the central column 19.

[0022] A locking component 2 is provided on one side of the support component 1. The locking component 2 includes a saw blade 21. Multiple positioning holes 22 are formed through the surface of the saw blade 21. A through hole 23 is formed at the center of the surface of the saw blade 21. A locking disc 24 is provided on one side of the saw blade 21, and a locking disc 25 is provided on the other side of the saw blade 21. Multiple positioning holes 26 are formed on the surface of both the locking disc 24 and the locking disc 25. A through hole 27 is formed at the center of the surface of both the locking disc 24 and the locking disc 25. A locking cover 28 is provided on the side of the locking disc 24 away from the saw blade 21. The outer surface of the locking cover 28 is... A locking port 29 is provided, and a locking bolt 210 is rotatably connected to the inner cavity of the locking port 29. Multiple protrusions 211 are fixedly connected to the outer surfaces of the locking disc 1 24 and the locking disc 25. A connecting component 3 is provided on the other side of the support component 1. The connecting component 3 includes a connecting disc 1 31. A cross post 32 is fixedly connected to one side surface of the connecting disc 1 31. A cross arc plate 33 is fixedly connected to the side surface of the cross post 32 away from the connecting disc 1 31. Multiple arc-shaped locking posts 34 are provided on the outer surface of the cross post 32. A connecting disc 2 35 is fixedly connected to the side of the arc-shaped locking posts 34 away from the connecting disc 1 31.

[0023] Among them, the inner diameter of the buffer pad 17 is the same as that of the positioning hole 22 and the positioning hole 26, the inner diameter of the center column 19 is the same as that of the through hole 23 and the through hole 27, and the outer side of the side column 15 is fixedly connected to the connecting plate 31.

When the saw blade 21 is stuck and stress is generated during later use, since the intersection of the arc-shaped locking pin 34, the cross pin 32 and the cross arc plate 33 are all arc surfaces, when no stress is generated, the arc-shaped locking pin 34 can lock the cross arc plate 33 and the cross pin 32 to drive rotation. When stress is generated, the arc-shaped locking pin 34 will detach from the cross arc plate 33 and the cross pin 32 due to the arc surface, and stop the cross arc plate 33 and the cross pin 32 from driving the saw blade 21 to rotate.
