Technical Field
[0001] This utility model relates to the field of ring saw technology, specifically a small brushless ring saw with a toothed saw blade. Background Technology
[0002] As a type of ring sawing device relying on circulating water cooling technology, the core working component of the water-cooled ring saw is a ring-shaped saw blade. During operation, the ring saw blade rotates at high speed and acts on the workpiece to complete the cutting action. The matching water cooling system continuously delivers cooling water to the sawing contact area. This can effectively remove the large amount of heat generated by the friction between the saw blade and the workpiece, prevent the workpiece from deforming due to high temperature, and avoid damage to the saw blade due to overheating. At the same time, the cooling water can also suppress and settle the dust generated during the cutting process, significantly improving the safety factor of the working environment.
[0003] Although existing circlip saws can meet basic material cutting needs, in long-term practical applications, the saw blades naturally wear down after prolonged continuous operation. As the saw blade thickness gradually decreases, its structural stability drops significantly, making it prone to swaying and deviation. This swaying and deviation not only directly causes a significant decline in cutting accuracy and a marked reduction in equipment operational stability, but also poses a major safety risk of saw blade breakage. Once the saw blade breaks, it will not only cause a sudden interruption of the cutting process, resulting in a direct loss of production efficiency, but the flying saw blade fragments may also pose a serious threat to the personal safety of on-site operators. Therefore, a toothed saw blade brushless small circlip saw is proposed to solve the above-mentioned problems. Utility Model Content

It solves the problem that after long-term continuous operation, the saw blade will naturally wear down, and as the thickness of the saw blade gradually decreases, its structural stability will drop significantly, making it prone to swaying and deviation. This swaying and deviation will not only directly cause a significant drop in cutting accuracy and a significant reduction in equipment operating stability, but also pose a major safety risk of saw blade breakage. Once the saw blade breaks, it will not only cause a sudden interruption of the cutting process and a direct loss of production efficiency, but the flying saw blade fragments may also pose a serious threat to the personal safety of on-site operators.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] In the embodiments, by Figure 1-5 This invention discloses a toothed saw blade brushless small ring saw. The invention includes a housing assembly 1 and a ring saw blade 2. A drive assembly 3 is provided inside the housing assembly 1 to drive the ring saw blade 2 to rotate. The drive assembly 3 transmits power to the ring saw blade 2 through a gear meshing structure. A connecting shell 4 is detachably installed on the outside of the housing assembly 1 via fasteners. The ring saw blade 2 is clamped inside the connecting shell 4. A connecting post 5 is fixedly connected to the inside of the connecting shell 4. A limiting sleeve 6 is fitted on the outside of each connecting post 5. A limiting groove 7 is provided on the outside of the limiting sleeve 6 to accommodate the ring saw blade 2. The ring saw blade 2 is placed inside the limiting groove 7. During operation, the drive assembly 3 is activated, transmitting power to the ring saw blade 2 through the gear meshing structure, causing the ring saw blade 2 to rotate stably within the limiting groove 7, thus completing the cutting operation.
[0018] This application transmits power through the gear meshing structure of the drive component 3, ensuring stable and efficient power transmission. The detachable design of the connecting shell 4 facilitates the disassembly, assembly, and maintenance of the ring saw blade 2. The limiting groove 7 of the limiting sleeve 6 precisely limits the ring saw blade 2, preventing it from shifting during rotation and improving cutting accuracy and equipment operation stability.
[0019] The outer shell 101 of the housing assembly 1 serves as the main support structure. The tail cover 102 is detachably installed at the end of the outer shell 101, which facilitates the opening of the tail cover 102 to inspect and maintain the drive component 3 and electrical components inside the housing assembly 1. The operating handle 103 is fixedly connected to the outside of the outer shell 101, which makes it convenient for the operator to hold the control equipment. The control switch 104 is located on the outside of the tail cover 102. The operator can start and stop the drive component 3 by pressing the control switch 104.
[0020] In this embodiment, the power reversing component 31 of the drive component 3 is fixed inside the housing assembly 1, and the rotating column 32 is rotatably connected to the inside of the housing assembly 1 and is in transmission cooperation with the power reversing component 31. After the power reversing component 31 is started, it drives the rotating column 32 to rotate around its own axis. The power gear 33 at one end of the rotating column 32 rotates synchronously with the rotating column 32. Since the power gear 33 meshes with the connecting gear 34 inside the annular saw blade 2, when the power gear 33 rotates, it drives the connecting gear 34 to rotate, thereby driving the annular saw blade 2 to rotate.
[0021] Meanwhile, the drive motor 301 of the power reversing assembly 31 is fixed inside the housing assembly 1. The first bevel gear 302 is fixed to the outside of the output shaft of the drive motor 301, and the second bevel gear 303 is fixed to the outside of the rotating column 32. The first bevel gear 302 and the second bevel gear 303 mesh with each other. After the drive motor 301 is started, the output shaft drives the first bevel gear 302 to rotate. The first bevel gear 302 drives the second bevel gear 303 to rotate through the meshing action, thereby driving the rotating column 32 to rotate synchronously, realizing the conversion and transmission of power direction.
[0022] The rotating column 32 is driven by the power reversing component 31, and the power is transmitted through the meshing of the power gear 33 and the connecting gear 34, so as to achieve stable power transmission and direction conversion, ensure smooth rotation of the ring saw blade 2, improve the stability of the cutting operation and the power transmission efficiency, and realize power reversal by adopting a bevel gear meshing structure. The drive motor 301 provides stable power, and the first bevel gear 302 and the second bevel gear 303 mesh tightly, with low power transmission loss and precise reversal, ensuring stable rotation of the rotating column 32 and providing a continuous and stable driving force for the ring saw blade 2.
[0023] In this embodiment, two symmetrically distributed auxiliary pressure rollers 8 are rotatably connected to the inner side of the connecting shell 4. Each auxiliary pressure roller 8 is elastically connected to the inner side of the connecting shell 4 through a connecting spring. Multiple bosses are provided on the outer side of the auxiliary pressure roller 8. Under the elastic force of the connecting spring, the bosses are tightly pressed against the outer side of the ring saw blade 2. When the ring saw blade 2 rotates, the auxiliary pressure roller 8 limits and guides the ring saw blade 2 through the pressing action of the bosses and the saw blade.
[0024] Among them, two symmetrical auxiliary pressure rollers 8 squeeze the ring saw blade 2 through the elastic force of the connecting spring, effectively limiting the radial runout of the ring saw blade 2. The boss design enhances the squeezing stability and guiding effect, assists the saw blade to rotate smoothly, and improves the cutting accuracy. At the same time, the elastic connection adapts to the slight deformation of the saw blade and avoids wear caused by hard contact.
[0025] The two connecting posts 5 inside the connecting shell 4 are symmetrically distributed vertically. Each connecting post 5 is fitted with a limiting sleeve 6 on its outer side. The symmetrically distributed connecting posts 5 and limiting sleeves 6 provide limiting support for the ring saw blade 2 on both sides, which can avoid the displacement caused by uneven force on one side. The water cooling plate 9 set inside the connecting shell 4 corresponds to the cutting area of the ring saw blade 2. During operation, the water cooling plate 9 releases coolant to cool the ring saw blade 2 and the cutting part, reduce saw blade wear and workpiece thermal deformation, extend the service life of the saw blade, and improve the cutting quality.
[0026] The top of the connecting shell 4 is connected to the baffle plate 10 via a rotating structure. A roller is installed at the end of the baffle plate 10 away from the connecting shell 4. During the cutting operation, the roller of the baffle plate 10 contacts the surface of the workpiece and rolls as the equipment moves, blocking the splashing of coolant. The positioning wheel 11 fixed at the bottom of the connecting shell 4 contacts the surface of the workpiece, providing support and positioning for the entire equipment and assisting the operator in controlling the cutting path.
[0027] Working principle: The operator holds the operating handle 103 on the outside of the housing assembly 1 and presses the control switch 104 on the outside of the tail cover 102 to start the equipment. After the drive motor 301 of the power reversing component 31 in the drive assembly 3 starts as the power source, its output shaft drives the first bevel gear 302 on the outside to rotate. The first bevel gear 302 realizes the power direction conversion through the meshing action with the second bevel gear 303 on the outside of the rotating column 32, thereby driving the rotating column 32 to rotate synchronously around its own axis. The power gear 33 fixed at one end of the rotating column 32 rotates synchronously with the rotating column 32. Through the meshing transmission with the connecting gear 34 on the inside of the ring saw blade 2, the power is transmitted to the ring saw blade 2, which drives the ring saw blade 2 to rotate stably in the limiting groove 7 of the limiting sleeve 6 on the outside of the connecting column 5 to complete the cutting operation.
[0028] During the cutting process, the connecting posts 5 and the limiting sleeves 6, which are symmetrically distributed on the inner side of the connecting shell 4, accurately position the ring saw blade 2 to prevent it from shifting during rotation. The two symmetrically arranged auxiliary pressure rollers 8, through the elastic force of the connecting spring, tightly squeeze the ring saw blade 2 with the outer boss, limiting the radial runout of the saw blade and assisting the saw blade to rotate smoothly. The water cooling plate 9 on the inner side of the connecting shell 4 releases coolant to the cutting area, which reduces the temperature of the ring saw blade 2 and the workpiece in time, and reduces saw blade wear and workpiece thermal deformation.
