Description

Technical Field

[0001] This utility model relates to the field of chainsaw repair tools, specifically a grinding device for chainsaw guide plates. Background Technology

[0002] As a highly efficient cutting tool, chainsaws are widely used in forestry, landscaping, and timber processing. The chainsaw guide plate is one of the key components of a chainsaw, providing support and guidance for the chain to ensure stable cutting operations. During frequent use, the chainsaw guide plate is constantly subjected to friction from the chain and erosion from various impurities in the working environment. As the usage time increases, wear and scratches will gradually appear on the surface of the guide plate. These defects not only reduce the cutting efficiency of the chainsaw but may also cause the chain to deviate or jam during operation, affecting the cutting accuracy and safety. Therefore, regular grinding and maintenance of the chainsaw guide plate is essential.

[0003] In traditional chainsaw guide plate grinding technology, manual grinding is the primary method. This method not only consumes a lot of manpower and time, but the grinding effect also largely depends on the experience and skill level of the workers. Since manual operation makes it difficult to ensure that the grinding force and angle are completely consistent each time, uneven grinding of the guide plate is likely to occur, resulting in poor surface flatness and affecting the overall performance of the chainsaw. In addition, some simple mechanical grinding equipment has limited functions and cannot flexibly adapt to chainsaw guide plates of different models and wear levels. It also cannot precisely adjust the grinding parameters during the grinding process, further limiting the quality and efficiency of grinding. This, to some extent, hinders the efficient production and development of the chainsaw industry. To address this, we propose a grinding device for chainsaw guide plates. Summary of the Invention

[0023] 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.

[0024] Please see Figure 1-4 A grinding device for chainsaw guide plates includes a base plate 1. Multiple sets of parallel and equidistantly distributed support feet 2 are fixedly installed on the bottom of the base plate 1. Anti-slip rubber pads are fixedly installed on the bottom of each support foot 2. A support platform 3 is fixedly installed on the top of the base plate 1. A fixing frame 4 is fixedly installed on the top of the support platform 3. A telescopic structure is provided on the side of the fixing frame 4. A grinding belt adjustment structure is provided at the other end of the fixing frame 4. A motor rotation structure is provided on the top side of the support platform 3. A fixing rod 17 is fixedly installed on one side of the top of the base plate 1. Multiple sets of equidistantly linearly distributed positioning holes are opened on the side of the fixing rod 17. A grinding lifting platform 18 is slidably installed on the outer side of the fixing rod 17. A grinding table structure is provided on the top of the grinding lifting platform 18. A positioning knob 19 is fixedly installed on the outer side of the grinding lifting platform 18.

[0025] Furthermore, the telescopic structure includes a telescopic rod 10 and a telescopic handle 11. The telescopic rod 10 is slidably mounted on the side of the fixed frame 4, and the telescopic handle 11 is slidably mounted on the outer side of the fixed frame 4. The telescopic handle 11 is fixedly connected to the telescopic rod 10. The telescopic structure can not only adjust the position of the fixed frame 4 to adapt to chainsaw guide plates of different sizes, but also finely adjust the contact distance between the grinding belt 13 and the guide plate according to actual needs during the grinding process. For example, when grinding the finer parts of the guide plate edge, the grinding belt 13 can be moved closer to or further away from the guide plate edge more accurately by slowly sliding the telescopic handle 11, avoiding over-grinding or under-grinding. In addition, the slide design on the side of the fixed frame 4 provides a stable guiding effect for the sliding of the telescopic rod 10, ensuring the smoothness and accuracy of the telescopic operation.

[0026] Furthermore, the motor rotation structure includes a motor mounting base 5, a motor 6, a first pulley 7, a belt 8, and a second belt 9. The motor mounting base 5 is fixedly installed on one side of the top of the support platform 3, and the motor 6 is fixedly installed on the top of the motor mounting base 5. The first pulley 7 is fixedly installed at the end of the output shaft of the motor 6, and the second belt 9 is rotatably installed on the side of the telescopic handle 11. The belt 8 is connected to the outer surface of the first pulley 7 and the second belt 9. In addition to fixing the motor 6, the motor mounting base 5 can also effectively reduce the impact of vibration generated during motor operation on the entire device. Through specific shock absorption design, such as setting shock-absorbing rubber pads between the mounting base and the support platform 3, it reduces vibration transmission and ensures the stability of the grinding process. At the same time, the dimensions of the first pulley 7 and the second belt 9 are precisely calculated to ensure that the grinding belt 13 obtains a suitable linear speed at the rated speed of the motor 6, which ensures grinding efficiency and prevents the guide plate from overheating or the grinding belt from excessive wear due to excessive speed. The belt 8 has a certain elasticity during transmission and can play a buffering role, further reducing the damage to various components caused by the impact force when the motor starts and stops.

[0027] Furthermore, the grinding belt adjustment structure includes a grinding belt adjustment rod 14, an adjustment slide rod 15, and an adjustment handle 16. The grinding belt adjustment rod 14 is rotatably mounted on the other end of the fixing bracket 4 corresponding to the end where the telescopic handle 11 is installed. The adjustment slide rod 15 is fixedly mounted on the outer side of the grinding belt adjustment rod 14. The adjustment slide rod 15 is arc-shaped, and an arc-shaped groove is formed on its side. The adjustment handle 16 is L-shaped, with one end rotatably mounted on the side of the grinding belt adjustment rod 14, and the other end slidably mounted in the groove of the adjustment handle 16. A grinding structure is provided on the other side of the grinding belt adjustment rod 14. The arc-shaped design of the adjusting slide bar 15, along with the arc-shaped groove on its side, provides the adjusting handle 16 with multi-dimensional adjustment possibilities. In actual operation, users can rotate the adjusting handle 16 at different angles and amplitudes according to the specific wear condition of the chainsaw guide plate to achieve more precise position and tension adjustment of the grinding belt 13. For example, when one side of the guide plate is severely worn, the grinding belt 13 can be slightly tilted to that side by adjusting the handle 16, so that the grinding belt 13 fits better with the worn surface and improves the grinding effect. In addition, the L-shaped design of the adjusting handle 16 makes it convenient for users to hold and operate, increasing the convenience and comfort of the adjustment process.

[0028] Furthermore, the grinding structure includes grinding belt pulleys 12 and a grinding belt 13. A set of grinding belt pulleys 12 are rotatably mounted on the upper and lower ends of the side of the grinding belt adjusting rod 14, and grinding belt pulleys 12 are rotatably mounted on the side of the telescopic handle 11. The outer surface of the grinding belt pulleys 12 is fitted with the grinding belt 13. The grinding belt pulleys 12 are made of special materials and surface treatment processes, which have high wear resistance and low friction coefficient. This not only extends the service life of the pulleys, but also ensures that the grinding belt 13 operates more smoothly and reduces the phenomenon of grinding belt deviation caused by pulley wear or friction. At the same time, the material of the grinding belt 13 is optimized according to different chainsaw guide plate materials and wear levels. For example, for guide plates with higher hardness, a grinding belt material with more wear resistance and stronger grinding force is used to improve grinding efficiency and quality. Moreover, the rotating shaft of the grinding belt pulleys 12 is precision machined to ensure the concentricity of the pulleys during rotation, further ensuring the stable operation of the grinding belt 13.

[0029] Furthermore, the grinding table structure includes a slide rail 20, a grinding platform 21, and a limiting plate 22. A set of parallel slide rails 20 are fixedly installed on the top of the grinding lifting platform 18. A limiting plate 22 is fixedly installed on the outward side of the slide rail 20. The grinding platform 21 is slidably installed on the top of the slide rail 20. The surface of the slide rail 20 is subjected to high-precision grinding treatment to ensure the smoothness and straightness of the grinding platform 21 during the sliding process. This makes the movement of the chainsaw guide plate on the grinding platform 21 more stable and helps to improve the uniformity of grinding. In addition to preventing the grinding platform 21 from sliding excessively, the limiting plate 22 can also serve as a reference mark to help users quickly determine the installation position of the guide plate. For example, users can align one end of the guide plate with the limiting plate 22 according to its length to improve operating efficiency. In addition, the surface of the grinding platform 21 adopts an anti-slip design, such as setting anti-slip texture or attaching anti-slip rubber pads, to ensure that the chainsaw guide plate will not slide during the grinding process, ensuring the safety and accuracy of grinding.

[0051] Grinding platform 21: The grinding platform 21 is installed on the top of the grinding lifting platform 18 via the slide rail 20. It is used to place the chainsaw guide plate and has an anti-slip design on the surface to prevent the guide plate from sliding.

[0052] Limiting plate 22: The limiting plate 22 is installed on the side of the slide rail 20 on the outward side. It can prevent the grinding platform 21 from sliding excessively and can also serve as a reference mark for the installation of the guide plate.

[0053] Working principle: When motor 6 is started, the motor rotation structure begins to work. The output shaft of motor 6 drives the first pulley 7 to rotate. The first pulley 7, through belt 8, cooperates with the second belt 9 rotatably mounted on the side of the telescopic handle 11, causing the second belt 9 to rotate synchronously. When the second belt 9 rotates, it drives the grinding belt pulley 12 connected to it to rotate, thereby driving the grinding belt 13, which surrounds the outer surface of the grinding belt pulley 12, to rotate at high speed, providing power for grinding the chainsaw guide plate. This structure converts electrical energy into mechanical energy, greatly improving grinding efficiency compared to traditional manual grinding, and ensuring stable grinding speed, avoiding the problem of uneven speed during manual grinding. During use, if it is necessary to adjust the relative position of the grinding device and the chainsaw guide plate... The telescopic structure allows for adjustment of the position of the fixed frame 4. By gripping and sliding the telescopic handle 11, the telescopic rod 10, which is fixedly connected to the telescopic handle 11, will slide synchronously on the side of the fixed frame 4, thus adjusting the position of the fixed frame 4. This function enables the device to adapt to the grinding needs of chainsaw guide plates of different sizes, improving its versatility. For example, when grinding longer or shorter chainsaw guide plates, the telescopic structure can be adjusted to allow the grinding belt 13 to better cover the area to be ground on the guide plate. The grinding belt adjustment structure is used to precisely adjust the working state of the grinding belt 13. By rotating the adjustment handle 16, one end of the adjustment handle 16 rotates on the side of the grinding belt adjustment rod 14, while the other end is within the arc-shaped groove of the adjustment slide rod 15. Sliding is achieved because the adjusting slide bar 15 is fixed to the outer side of the grinding belt adjusting rod 14. Therefore, rotating the adjusting handle 16 will cause the grinding belt adjusting rod 14 to rotate, thereby adjusting the position of the grinding belt pulley 12 and the tension of the grinding belt 13. This ensures that the grinding belt 13 maintains uniform contact with the chainsaw guide plate surface during grinding, guaranteeing grinding accuracy, preventing uneven grinding, improving the quality of the ground chainsaw guide plate, and ultimately enhancing the overall performance of the chainsaw. When dealing with chainsaw guide plates of different wear levels, adjustments can be made using the grinding lifting platform 18 and its related structures. The positioning knob 19 on the outer side of the grinding lifting platform 18 engages with the positioning hole on the side of the fixing rod 17. Loosening the positioning knob... After step 19, the grinding lifting platform 18 can slide up and down along the fixed rod 17. After adjusting to a suitable height, tighten the positioning knob 19 to fix it. During the grinding process, the chainsaw guide plate is placed on the grinding platform 21. The slide rail 20 at the bottom of the grinding platform 21 cooperates with the slide rail 20 at the top of the grinding lifting platform 18, so that the grinding platform 21 can slide on the slide rail 20, which facilitates the adjustment of the guide plate position. At the same time, the limiting plate 22 on the outward side of the slide rail 20 can prevent the grinding platform 21 from sliding excessively, playing a positioning and protection role, ensuring the safety and stability of the grinding process. By adjusting the height of the grinding lifting platform 18, the grinding belt 13 can maintain appropriate contact with the guide plate surface with different wear levels, ensuring the grinding effect.
