Description

Technical Field

[0001] The utility model relates to the technical field of chain saws, and specifically relates to a tool assembly for a chain saw. Background Art

[0002] As an efficient stone processing machine widely used in the infrastructure construction field, the development history of the chain saw is long. As early as in ancient times, people began to use simple tools for stone mining and processing. With the continuous progress of technology, the technology of the chain saw has been greatly improved. In modern society, the chain saw has become an indispensable important equipment in the infrastructure construction field.

[0003] The main uses of the chain saw include operations such as foundation pit excavation, tunnel excavation, and mine mining. In these engineering projects, rock geology is often encountered, and excavation and cutting work need to be carried out. With its excellent cutting ability and high operating efficiency, the chain saw has become a powerful tool in these works.

[0004] The working principle of the chain saw is that the chain is driven by an electric motor or an internal combustion engine. Cutting tools are installed on the chain, and the high-speed rotating chain drives the cutting tools to cut the stone. The cutting tools of the chain saw are usually made of cemented carbide materials, which have high hardness and wear resistance and can adapt to various complex cutting conditions.

[0005] In the current structure of the chain saw tool assembly, it includes several tool seats and the tools installed on these tool seats. Among them, the tool seats are specially provided with screws for firmly fixing the tools on the tool seats. This design was originally intended to ensure more stable and reliable installation of the tools on the tool seats through the stable limit of the screws.

[0006] However, it is found in actual applications that this way of fixing the tool with screws has certain limitations. Specifically, it can only fix the tool in the middle position of the tool seat and cannot be adjusted or fixed in other positions. The reason for this situation is mainly that the design and installation method of the screws limit the adjustability of the tool.

[0007] During the cutting process, since the tool cannot be adjusted in position according to actual needs, it is impossible to contact the wall to be cut in the first time. This leads to the tool seat directly contacting the wall during the cutting process, resulting in unnecessary wear and damage. From a technical perspective, this design defect may stem from the initial design concept and manufacturing process. In the design stage, the flexible adjustment requirements of the tool during the actual cutting process and the influence of the contact time and position between the tool and the wall on the wear of the tool seat may not have been fully considered.

[0008] In addition, during the manufacturing process, the installation position and fixing method of the screw may not have been fully optimized and tested, resulting in the limitation that the tool can only be fixed in the middle position. Therefore, a tool assembly for a chain arm saw is proposed to solve the above problems. Summary of the Invention

[0009] Aiming at the deficiencies of the prior art, the present utility model provides a tool assembly for a chain arm saw, which has the advantages of being able to flexibly adjust the position of the tool, etc., and solves the problem that the tool holder of the existing chain arm saw tool assembly is easily worn due to the tool being fixed only in the middle position.

[0010] To sum up, the present utility model provides the following technical solution: A tool assembly for a chain arm saw, including a tool holder, a tool, a pressing plate, a positioning strip, and a tool installation position. The tool is installed on one side of the tool holder, and its cutting edge faces the object to be cut. The pressing plate is fixed on the tool holder and cooperates with the tool installation position to press the tool tightly. The positioning strip is fixedly connected to the pressing plate and contacts the side surface of the tool to limit the movement of the tool on the tool holder.

[0011] Furthermore, a plurality of tool installation positions are fixedly installed on the tool holder, and one tool can be fixedly installed on each tool installation position, and the tool installation positions are evenly distributed.

[0012] By adopting the above technical solution, this design enables each tool installation position to firmly accommodate a tool, ensuring that the tool will not loosen or shift during use. The tight fit between the tool installation position and the tool provides a reliable guarantee for the efficient cutting of the chain arm saw.

[0013] Furthermore, it also includes bolts. A threaded hole is provided on one side of the pressing plate, and the pressing plate is fixed on the tool installation position and presses the tool through the cooperation of the bolt and the threaded hole.

[0014] By adopting the above technical solution, this detachable connection method, on the one hand, facilitates the replacement and maintenance of the tool; on the other hand, through the pressing action of the pressing plate, it can effectively prevent the tool from loosening or displacing during operation, thus ensuring the working stability and safety of the chain arm saw.

[0015] Furthermore, the plurality of tool installation positions are arranged in a straight line in a single row on the tool holder, and the straight-line arrangement is perpendicular to the traveling direction of the chain arm saw.

[0016] By adopting the above technical solution, this arrangement is not random but carefully designed to achieve the best cutting performance. The linear arrangement is perpendicular to the walking direction of the chain arm saw, enabling the cutting tool to withstand a uniform cutting force when cutting into the material to be cut, thereby improving the cutting efficiency and quality. In addition, this vertical layout also helps to reduce the vibration and noise of the chain arm saw during operation and extend the service life of the equipment.

[0017] Furthermore, the cutting tools are distributed in a polar staggered manner at each of the cutting tool mounting positions.

[0018] By adopting the above technical solution, specifically, at the cutting tool mounting positions with odd numbers, the cutting tools can be fixed with a leftward polarity; while at the cutting tool mounting positions with even numbers, the cutting tools can be fixed with a rightward polarity, and so on. Thus, the cutting tools can be flexibly configured at different cutting tool mounting positions according to actual needs, rather than being limited to the middle position only.

[0019] Compared with the prior art, the present utility model provides a cutting tool assembly for a chain arm saw, which has the following beneficial effects:

[0020] For this cutting tool assembly for a chain arm saw, through the mutual cooperation of the cutting tools, pressure plates, positioning strips, cutting tool mounting positions, threaded holes and bolts on the tool holder, the fixation of the cutting tools is more stable and reliable, effectively avoiding the loosening or displacement of the cutting tools during use. At the same time, this also facilitates the cutting tools to more accurately contact the side wall of the wall to be cut, thereby enabling more efficient cutting work. Since the cutting tools can be more stably fixed on the tool holder and can more accurately contact the side wall of the wall to be cut, the wear on the tool holder is reduced during the cutting process, not only extending the service life of the tool holder, reducing the maintenance cost, but also improving the efficiency and quality of the entire cutting process. In addition, since the cutting tools are more stably fixed, the operator is also safer and more reliable when using the chain arm saw, reducing the occurrence of safety accidents caused by the loosening or displacement of the cutting tools.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0028] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a tool assembly for a chain arm saw, including a tool holder 1, a tool 2, a pressure plate 3, a positioning strip 4 and a tool mounting position 5. The tool 2 is installed on one side of the tool holder 1, and its cutting edge faces the object to be cut. The pressure plate 3 is fixed on the tool holder 1 and cooperates with the tool mounting position 5 to press the tool 2 tightly. The positioning strip 4 is fixedly connected to the pressure plate 3 and contacts the side surface of the tool 2 to limit the movement of the tool 2 on the tool holder;

[0029] Through the mutual cooperation of the tool 2, the pressure plate 3, the positioning strip 4, the tool mounting position 5, the threaded hole 6 and the bolt 7 on the tool holder 1, the fixation of the tool is more stable and reliable, effectively avoiding the situation of loosening or displacement of the tool during use. At the same time, this also facilitates the tool to more accurately contact the side wall of the wall to be cut, so as to be able to carry out cutting work more efficiently. Since the tool can be more stably fixed on the tool holder and can more accurately contact the side wall of the wall to be cut, the wear on the tool holder is reduced during the cutting process, not only extending the service life of the tool holder, reducing the maintenance cost, but also improving the efficiency and quality of the entire cutting process. In addition, since the fixation of the tool is more stable, the operator is also safer and more reliable when using the chain arm saw, reducing the occurrence of safety accidents caused by the loosening or displacement of the tool.

[0030] As Figures 1 to 4 shown, in this embodiment, it is to make the fixation of the tool more stable and reliable, effectively avoiding the situation of loosening or displacement of the tool during use. At the same time, this also facilitates the tool to more accurately contact the side wall of the wall to be cut, so as to be able to carry out cutting work more efficiently.

[0031] It should be noted that a plurality of tool mounting positions 5 are fixedly installed on the tool holder 1, and a tool 2 can be fixedly installed on each tool mounting position 5. The tool mounting positions 5 are evenly distributed, and each position is carefully designed to adapt to the precise installation of the tool 2. This design enables each tool mounting position 5 to firmly accommodate a tool 2, ensuring that the tool 2 will not loosen or shift during use. The close fit between the tool mounting position 5 and the tool 2 provides a reliable guarantee for the efficient cutting of the chain arm saw.

[0032] It can be understood that it also includes a bolt 7. A threaded hole 6 is provided on one side of the pressing plate 3. The pressing plate 3 is fixed on the tool mounting position 5 and presses the tool 2 through the cooperation of the bolt 7 and the threaded hole 6. During installation, first place the tool 2 on the tool mounting position 5 and ensure its position is accurate and stable. Then, place the pressing plate 3 on the tool 2 so that the threaded hole 6 is aligned with the fixing structure on the tool mounting position 5. Finally, pass the bolt 7 through the threaded hole 6 on the pressing plate 3 and tighten it to fix the tool 2 on the tool mounting position 5. In this process, the pressing plate 3 presses the tool 2 tightly through the cooperation with the bolt 7, making it firmly fixed on the tool holder 1. This detachable connection method, on the one hand, facilitates the replacement and maintenance of the tool 2; on the other hand, through the pressing action of the pressing plate 3, it can effectively prevent the tool 2 from loosening or displacing during operation, thus ensuring the working stability and safety of the chain arm saw.

[0033] In addition, the plurality of tool mounting positions 5 are arranged in a straight line on the tool holder 1, and the straight line arrangement is perpendicular to the traveling direction of the chain arm saw (the chain arm saw is a known prior art and is not shown in the figure). On the tool holder 1, the plurality of tool mounting positions 5 are arranged in the form of a straight line. This arrangement is not random but is carefully designed to achieve the best cutting performance. The straight line arrangement is perpendicular to the traveling direction of the chain arm saw, enabling the tool 2 to withstand a uniform cutting force when cutting into the material to be cut, thereby improving the cutting efficiency and quality. In addition, this vertical layout also helps to reduce the vibration and noise of the chain arm saw during operation and extend the service life of the equipment.

[0034] In this embodiment, the tools 2 are distributed in a polar staggered manner on each tool mounting position 5, rather than being fixed at the geometric center position in all cases. This arrangement can be dynamically adjusted according to actual needs. By alternately arranging the tools 2 on adjacent tool mounting positions 5, the tools 2 are distributed in a polar staggered manner on the tool holder 1. Specifically, on the tool mounting positions 5 with odd numbers, the tools 2 can be fixed in the leftward polarity; while on the tool mounting positions 5 with even numbers, the tools 2 can be fixed in the rightward polarity, and so on. Thus, the tools 2 can be flexibly configured on different tool mounting positions 5 according to actual needs, rather than being limited to the middle position only.

[0035] The working principle of the above embodiments is as follows:

[0036] (1) Installation of the cutting tool 2:

[0037] Insert the cutting tool 2 into the tool installation position 5 of the tool holder 1, with the cutting edge of the cutting tool 2 facing the object to be cut. The close arrangement of the tool installation positions 5 ensures that the cutting tool 2 can be accurately aligned with the rotation axis of the tool holder 1 during installation, thus ensuring the uniform transmission of the cutting force. In addition, the cutting tools 2 are arranged in a polar staggered manner at each tool installation position 5. This arrangement can effectively improve the cutting efficiency and reduce vibration and noise during the cutting process.

[0038] (2) Positioning and fixing of the cutting tool 2:

[0039] Install the positioning strip 4 onto the tool installation position 5, and ensure the position accuracy of the cutting tool 2 during the cutting process by the cooperation of the positioning strip 4 and the positioning holes on the cutting tool 2. Insert the bolt 7 into the threaded hole 6 and tighten it to firmly fix the pressure plate 3 to the tool holder 1. This design realizes a detachable connection through the cooperation of the bolt 7 and the threaded hole 6, making the replacement and maintenance of the cutting tool 2 more convenient. At the same time, the tightened pressure plate 3 can effectively prevent the cutting tool 2 from loosening or displacing during operation, thereby ensuring the working stability and safety of the chain arm saw. In order to fix the cutting tool 2 more firmly to the tool holder 1, the positioning strip 4 adopts special materials and designs. The close contact between the positioning strip 4 and the cutting tool 2 ensures the stability of the cutting tool 2 during the cutting process, and also avoids unnecessary wear and vibration.

[0040] (3) Cutting process:

[0041] The tool holder 1 starts to rotate, driving the cutting tool 2 to perform a circular motion around its axis. During the rotation, the cutting edge of the cutting tool 2 continuously cuts into the object to be cut and performs cutting operations. Since the cutting edge of the cutting tool 2 always faces the object to be cut, and at the same time, the high-speed rotation of the tool holder 1 and the strict installation and fixing method of the cutting tool 2 enable the cutting tool 2 to stably contact and cut into the material to be cut, thus realizing efficient cutting operations. The rotation direction is perpendicular to the walking direction of the chain arm saw, which can effectively reduce the horizontal component of the cutting force, thereby reducing vibration and error during the cutting process. The cutting tools 2 on the tool holder 1 adopt a multi-edge design, and multiple cutting edges perform cutting operations simultaneously, which can effectively improve the cutting efficiency. In addition, since the multi-edge design can evenly distribute the cutting force to each cutting edge, the wear of the cutting tool 2 during the processing is reduced. The multiple tool installation positions 5 are arranged in a straight line on the tool holder 1, which can effectively increase the cutting width and reduce the repeated operations during the cutting process, thereby improving the production efficiency.

[0042] Compared with the prior art: for the tool assembly of this chain arm saw, through the mutual cooperation of the tool 2, the pressing plate 3, the positioning strip 4, the tool mounting position 5, the threaded hole 6 and the bolt 7 on the tool holder 1, the fixing of the tool is more stable and reliable, effectively avoiding the loosening or displacement of the tool during use. At the same time, this also facilitates the tool to more accurately contact the side wall of the wall to be cut, so as to be able to carry out the cutting work more efficiently. Since the tool can be more stably fixed on the tool holder and can more accurately contact the side wall of the wall to be cut, the wear on the tool holder is reduced during the cutting process, not only extending the service life of the tool holder, reducing the maintenance cost, but also improving the efficiency and quality of the entire cutting process. In addition, due to the more stable fixing of the tool, the operator is also safer and more reliable when using the chain arm saw, reducing the occurrence of safety accidents caused by the loosening or displacement of the tool.
