Description

Technical Field

[0001] This utility model relates to the field of ring saw technology, specifically a water tray guide plate for a toothed saw blade brushless small ring saw. Background Technology

[0002] In various fields such as building decoration, pipeline construction, and stone processing, efficient and precise cutting operations are crucial for ensuring project quality and progress. Brushless mini ring saws, as commonly used cutting equipment in these fields, are highly favored due to their unique structure and performance. A brushless mini ring saw refers to a small cutting device that uses a brushless motor as a power source and is equipped with a ring saw blade for cutting operations. Compared with traditional brushed motors, brushless motors have the advantages of high operating efficiency, long service life, and low maintenance costs. The structural design of the ring saw blade makes it more adaptable to cutting operations in narrow spaces or at special angles, and can meet the cutting needs under various complex working conditions.

[0003] While existing circlip saws can complete basic cutting tasks, their limitations become increasingly apparent with prolonged use. The saw blade experiences continuous wear during high-frequency operations, and as the blade thins, its rigidity and structural stability decrease, leading to problems such as blade wobbling and cutting trajectory deviation. This not only directly results in poor cutting accuracy, causing dimensional deviations in the finished product to exceed standard ranges, but also poses serious safety hazards. More importantly, the impact resistance of the worn saw blade is significantly reduced, making it highly susceptible to breakage. Once broken, it not only causes sudden work stoppages and slows progress, but the flying saw blade fragments can also cause personal injury to operators and damage other tools or workpieces on site. Furthermore, existing equipment lacks effective auxiliary stabilizing structures during saw blade wear, failing to provide timely posture correction and limiting of the worn saw blade, further exacerbating the probability and severity of the aforementioned problems. Therefore, a toothed saw blade brushless small circlip saw with a water tray guide plate is proposed to address these issues. Utility Model Content

Detailed Implementation

[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 1-6This invention discloses a water tray guide plate for a toothed saw blade brushless small ring saw. The invention includes a connecting housing 1 and a ring-shaped cutting saw blade 2. An internal gear 6 is fixedly connected to the inner side of the ring-shaped cutting saw blade 2. A power drive assembly 3 for driving the ring-shaped cutting saw blade 2 to rotate and cut is provided on the inner side of the connecting housing 1. The power drive assembly 3 meshes with the internal gear 6 for transmission. A protective shell 4 is detachably connected to the outer side of the connecting housing 1 via fasteners. An auxiliary limiting assembly 5 is detachably connected to the inner side of the protective shell 4 via fasteners. The auxiliary limiting assembly 5 includes two partitions 51, a middle support plate 52, a connecting bearing 53, and an auxiliary component 54. The two partitions 51 and the middle support plate 52 are detachably connected to the inner side of the protective shell 4 via fasteners. The middle support plate 52, the connecting bearing 53, and the internal gear 6 are all sandwiched between the two partitions 51. The auxiliary component 54 is sleeved on the outer side of the connecting bearing 53.

[0018] When the auxiliary component 54 is an auxiliary gear, during use, after the power drive component 3 is started, it drives the annular cutting saw blade 2 to rotate and cut through the meshing transmission with the internal gear 6. During this process, the auxiliary component 54 in the auxiliary limiting component 5 rotates synchronously with the internal gear 6 under the support of the connecting bearing 53. The two partitions 51 and the middle support plate 52 together provide limiting support for the connecting bearing 53 and the internal gear 6, ensuring the stability of the annular cutting saw blade 2 when the internal gear 6 drives it to rotate.

[0019] By adding an auxiliary limiting component 5, consisting of two partition plates 51, a middle support plate 52, a connecting bearing 53, and an auxiliary component 54, to the internal gear 6 and the power drive component 3, the auxiliary limiting component 54 meshes with the internal gear 6. This provides a double limiting support for the rotation of the annular cutting saw blade 2, effectively preventing the annular cutting saw blade 2 from shifting or shaking during high-speed rotation and improving cutting accuracy. At the same time, the protective shell 4 and the connecting shell 1, as well as the auxiliary limiting component 5 and the protective shell 4, are all connected by fasteners for easy maintenance and replacement of components, thus improving the service life and ease of use of the equipment.

[0020] Meanwhile, the auxiliary component 54 can also be replaced with a guide wheel. The guide wheel has a limiting groove on its outer side for rotating and limiting the ring cutting saw blade 2, and the internal gear 6 is located inside the limiting groove.

[0021] In this embodiment, a cutting blade is provided on the outer side of the annular cutting saw blade 2. The thickness of the annular cutting saw blade 2 is 3-5mm, and the thickness of the cutting blade is 4-6mm. A water guide groove is provided on the inner side of the partition plate 51, and the water guide groove is connected to the outer interface. A water outlet is provided on the outer side of the partition plate 51. Coolant can be sprayed onto the surface of the annular cutting saw blade 2 through the water guide groove and the water outlet, which can cool the annular cutting saw blade 2 and improve its service life.

[0022] In this embodiment, the connecting housing 1 includes an outer shell 101, a tail cover 102, an operating handle 103, and a control switch 104; During assembly, the tail cover 102 is detachably connected to the end of the housing 101 by fasteners, the operating handle 103 is fixedly connected to the outside of the housing 101 to ensure that the operator can hold it stably, and the control switch 104 is fixedly installed on the outside of the tail cover 102 and is electrically connected to the power drive assembly 3. In use, the operator can hold the operating handle 103 to stably control the movement direction of the entire equipment. By pressing the control switch 104 on the outside of the tail cover 102, the start and stop of the power drive component 3 can be controlled. When it is necessary to maintain the power drive component 3 inside the connecting housing 1, the tail cover 102 can be removed to directly contact the relevant parts, making the maintenance and repair of the parts inside the connecting housing 1 more convenient and further improving the ease of use of the equipment.

[0023] In this embodiment, the power drive assembly 3 includes a drive motor 31, a first bevel gear 32, a rotating column 33, a second bevel gear 34, and a pinion 35; During assembly, the drive motor 31 is fixedly installed inside the connecting housing 1, the first bevel gear 32 is fixedly sleeved on the outside of the output shaft of the drive motor 31, the rotating column 33 is rotatably connected to the inside of the protective housing 4 through the bearing, and the second bevel gear 34 and the pinion 35 are sequentially fixedly sleeved on the outside of the rotating column 33 to ensure that the outside of the first bevel gear 32 and the outside of the second bevel gear 34 mesh with each other, and at the same time, the outside of the pinion 35 meshes with the outside of the internal gear 6. During operation, after the drive motor 31 starts, it drives the first bevel gear 32 on the output shaft to rotate. The first bevel gear 32 drives the rotating column 33 to rotate through meshing with the second bevel gear 34. The rotating column 33 then drives the pinion 35 on it to rotate synchronously. The pinion 35 drives the annular cutting saw blade 2 to rotate and cut through meshing with the internal gear 6.

[0024] The power drive assembly 3 uses the meshing of bevel gears to change the direction of power. In conjunction with the transmission of the rotating column 33 and the pinion 35, it can stably and efficiently transmit the power of the drive motor 31 to the internal gear 6, thereby driving the annular cutting saw blade 2 to rotate. This transmission structure is compact, with low power transmission loss, high transmission efficiency, and stable connection of each component, which can ensure that the annular cutting saw blade 2 obtains continuous and stable cutting power, thereby improving the cutting effect and work efficiency.

[0025] In this embodiment, the mounting post 7 is assembled on the inner side of the protective shell 4 by welding or fastener connection. The axial direction of the mounting post 7 is consistent with the rotation axis direction of the annular cutting saw blade 2. The anti-deviation component 8 is sleeved and installed on the outer side of the mounting post 7, so that the anti-deviation component 8 is fixed on the outer side of the mounting post 7.

[0026] When the anti-deviation component 8 is a guide wheel, a limiting groove adapted to the annular cutting saw blade 2 and the internal gear 6 is opened on the outside of the guide wheel. When the internal gear 6 rotates, it is located inside the limiting groove. The limiting groove radially limits the internal gear 6 and the annular cutting saw blade 2 to prevent radial deviation during rotation. Meanwhile, the anti-deviation component 8 can also be an auxiliary gear that meshes with the internal gear 6.

[0027] Furthermore, the number of mounting posts 7 is set to two, and the two mounting posts 7 are distributed symmetrically on the outside of the power drive component 3. Each mounting post 7 is fitted with an anti-deviation component 8 on its outside. The limiting grooves of the two anti-deviation components 8 work together to limit the ring cutting saw blade 2 and the internal gear 6, further improving the rotational stability and cutting accuracy, and avoiding equipment damage or reduction in cutting quality due to excessive force on one side.

[0028] Meanwhile, a water baffle 9 is rotatably connected to the protective shell 4 via a hinge support at a pre-set installation position at the top of the protective shell 4, allowing the water baffle 9 to rotate freely around the axis of the hinge support to adapt to different cutting angles and working conditions. A limiting roller is rotatably connected to the end of the water baffle 9 away from the hinge support via a rotating shaft, and the outer wall of the limiting roller is in contact with the wall. A positioning wheel 10 is fixedly connected to the bottom of the protective shell 4 by welding or fasteners. The bottom of the positioning wheel 10 contacts the surface of the workpiece to be cut. During the cutting process, the positioning wheel 10 can roll along the surface of the workpiece, providing support and positioning for the entire equipment. This allows the operator to more easily control the direction of equipment movement during the cutting process, reducing cutting deviation and improving cutting accuracy. At the same time, it reduces the labor intensity of the operator. The overall structure improves the safety, practicality, and ease of operation of the equipment.

[0029] Example 2: Based on Example 1, this example adds an auxiliary pressure roller 11. Two auxiliary pressure rollers 11 are elastically connected to the protective housing 4 via a connecting spring at a preset installation position on the inner side of the protective housing 4. The two auxiliary pressure rollers 11 are distributed symmetrically on the outer side of the annular cutting saw blade 2. The auxiliary pressure rollers 11 can move towards or away from the annular cutting saw blade 2 under the elastic force of the connecting spring. Multiple evenly distributed bosses are provided on the outer side of the auxiliary pressure rollers 11, and multiple grooves with shapes and sizes matching the bosses are opened on the outer side of the annular cutting saw blade 2. After assembly, under the elastic force of the connecting spring, the auxiliary pressure rollers 11 apply pressure towards the annular cutting saw blade 2, so that the bosses on the outer side of the auxiliary pressure rollers 11 and the grooves on the outer side of the annular cutting saw blade 2 are pressed and fitted together. When the annular cutting saw blade 2 rotates, the bosses and grooves cooperate with each other to limit the rotation of the annular cutting saw blade 2. The distance from the internal gear 6 to the first groove is 2.5-3.5mm.

[0030] Two symmetrically distributed auxiliary pressure rollers 11 apply radial pressure to the annular cutting saw blade 2 through the elastic force of the connecting springs. This effectively suppresses the vibration and radial runout generated by the annular cutting saw blade 2 during high-speed rotation, improving cutting accuracy and stability. The bosses on the outer side of the auxiliary pressure rollers 11 press and fit against the grooves on the outer side of the annular cutting saw blade 2, which not only enhances the limiting effect and prevents the saw blade from shifting circumferentially, but also further transmits torque, helps stabilize the rotation speed of the saw blade, and prevents the annular cutting saw blade 2 from shifting backward. The elastic connection method allows the auxiliary pressure rollers 11 to adapt to the slight deformation of the saw blade, avoiding saw blade damage caused by rigid contact. At the same time, it reduces vibration and noise, extends the service life of the saw blade and the equipment, and the overall structure improves the cutting stability, accuracy, and user comfort of the equipment.
