Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a tool limiting structure for taking out a tool. Background Art

[0002] The tool picking mechanism is an automatic tool changing system used for quickly switching and replacing tools in automated processing equipment. This system usually consists of a tool magazine with multiple tools and corresponding tool pickers, which can realize the function of picking up and replacing multiple tools at the same time. The automatic tool changing system is usually used in automated processing equipment such as CNC machine tools, lathes, and milling machines. It can improve production efficiency, reduce manual intervention, and can quickly switch between different types or sizes of tools as needed during the processing process to adapt to different processing requirements. This device plays a very important role in mechanical processing, especially in large-scale production and automated production lines, which can significantly improve production efficiency and processing accuracy.

[0003] The tool picker machine uses limit plates to limit the descent of multiple tool pickers. The function of the limit plates in the tool picker machine is to control and limit the descent position of multiple tool pickers. Tool pickers are usually used to remove workpieces or perform other operations during the processing process, and the limit plates ensure that the tool pickers stop at the correct position when descending. By setting and adjusting the position of the limit plates, it can be ensured that the tool pickers can stop accurately at the required position when descending, thereby achieving accurate processing of the workpiece. This ability to control position is very important for processing accuracy and operation safety.

[0004] Conventional limit plates are usually made of high-strength stainless steel plates, which results in a large load when the limit plates are suspended. When the limit plates limit the tool picker, they cannot cushion the descent of the tool picker and are prone to scratching the outer surface of the tool picker. Therefore, we propose a multi-station lifting frame for fixing the tool picker to solve this problem. Summary of the Invention

[0005] In order to solve the above problems, the utility model proposes a tool limiting structure for knife removal, so as to more accurately solve the problem that the above conventional limiting plates usually adopt stainless steel plates with higher strength, resulting in a large load when the limiting plates are hung, and when the limiting plates limit the knife remover, they cannot cushion the descent of the knife remover and are prone to scratching the outer surface of the knife remover.

[0022] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0023] Please refer to Figure 1-Figure 3 The utility model proposes a tool limiting structure for taking a knife, including a knife taking mechanism 1 and a limiting plate 2. The knife taking mechanism 1 includes a supporting vertical plate 3 and a lifting plate 4. The rear side of the limiting plate 2 is fixedly connected to the front side of the supporting vertical plate 3. A plurality of arc-shaped holes 6 are opened on the top of the limiting plate 2. One side of the arc-shaped hole 6 is open. The front side of the supporting vertical plate 3 is provided with a knife taking mechanism 1. The knife taking mechanism 1 is fixedly connected to the lifting plate 4. A plurality of knife takers 5 are fixedly installed on the lifting plate 4. The arc-shaped holes 6 are adapted to the corresponding knife takers 5.

[0024] It should be noted that the arc-shaped hole formed on the limiting plate is just large enough for the knife-picking component of the knife-picking device to pass through, while the outer shell of the knife-picking device is limited by the arc-shaped hole due to its diameter.

[0025] In this embodiment, a plurality of circular holes are opened on the top of the limiting plate 2, and spring telescopic rods 7 are fixedly installed in the circular holes. The spring telescopic rods 7 are arranged in multiple sections.

[0026] It should be noted that the spring telescopic rod is designed as a multi-section structure, and the spring resistance of each section can be different, so that the spring telescopic rod can provide different damping or elastic effects in different telescopic stages or force conditions, so that the spring buffering force applied to the knife remover during the descent process changes from small to large, making the force process of the knife remover more stable and preventing the impact force from causing damage to the internal components of the knife remover.

[0027] In this embodiment, the inner side wall of the arc-shaped hole 6 is ground and polished, and the opening of the arc-shaped hole 6 is rounded.

[0028] It should be noted that grinding and polishing can make the inner wall surface of the arc hole smoother, reduce surface roughness and unevenness, and polishing can eliminate the roughness of the inner wall of the arc hole, reduce surface defects, improve corrosion resistance, extend service life, and facilitate limiting the knife remover to prevent the outer shell of the knife remover from being scratched.

[0029] In this embodiment, a plurality of threaded holes 8 are formed on the top of the limiting plate 2 , and a plurality of threaded grooves are formed on the bottom of the supporting vertical plate 3 , and the threaded holes 8 are matched with the threaded grooves.

[0030] In this embodiment, a metal sheet plate 9 is fixedly connected to the bottom of the limiting plate 2 , and one side of the metal sheet plate 9 is fixedly connected to the supporting vertical plate 3 via a plurality of bolts.

[0031] In this embodiment, an extension plate 10 is fixedly mounted on the front side of the metal sheet plate 9 , and two assembly holes are provided on the front side of the extension plate 10 .

[0032] It should be noted that the metal sheet fixed to the bottom of the limit plate can increase the overall rigidity of the limit plate, improve its ability to resist bending and torsion, thereby enhancing the stability and durability of the limit plate. The setting of the metal sheet plate allows for more connection points with other components, making the support force on the limit plate more uniform and preventing the limit plate from falling off when impacted.

[0033] In this embodiment, the material of the limiting plate 2 is aluminum alloy, and manganese is added into the limiting plate 2 .

[0034] It should be noted that compared with other metal materials such as steel or stainless steel, aluminum alloy plates of the same size are lighter, making aluminum alloy plates an ideal choice in suspension applications. At the same time, aluminum alloy also has good corrosion resistance. The addition of manganese can improve the grain structure of aluminum alloy, increase its strength and hardness, improve the hot working performance of aluminum alloy, and help improve the impact resistance of aluminum alloy.

[0035] In this embodiment, the limiting plate 2 is manufactured by a heat treatment process, and the outer surface of the limiting plate 2 is sprayed.

[0036] It should be noted that aluminum alloys with added manganese have strong thermal processing properties. The heat treatment process can improve the grain structure of the aluminum alloy, increase its strength and hardness, thereby enhancing its impact resistance. Through spraying technology, a coating is formed on the surface of the aluminum alloy to provide protection and prevent the aluminum alloy surface from corrosion and wear.

[0037] In this embodiment, the working principle of the device is: the limit plate proposed in this utility is a part of a knife picking machine, which is used to limit the position of multiple knife pickers when picking up knives, and limit the descending distance of the knife pickers. The knife pickers are limited by the cooperation of the arc hole on the limit plate and the outer shell of the knife picker. One side of the arc hole is opened to facilitate the lifting and taking and placing of the tool. Multiple spring telescopic rods are used to abut the annular edge on the outer shell of the knife picker to buffer the impact force generated by the descent of the knife picker, and the material setting of manganese-aluminum alloy, as well as heat treatment and coating settings, improve the strength and wear resistance of the limit plate.

[0038] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
