Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an auxiliary tooling for replacing the cutter head of a cutting machine, so as to solve the technical problems that on the one hand, there is a short service life due to insufficient metal thickness during use, and on the other hand, there is an easy omission of tooling due to a large number of parts.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an auxiliary tooling for replacing the cutter head of a cutting machine, including a sleeve, an installation groove is opened at the top of the sleeve, a first magnet is installed at the bottom of the installation groove, a first wrench mechanism is snap-fitted in the installation groove through a clamping block, the first wrench mechanism includes a first main rod, matrix-shaped slots are opened at both ends inside the first main rod, the bottom ends of the slots are magnetically connected to inserting rods through second magnets, two groups of inserting rods are provided, and one ends of the two groups of inserting rods are respectively fixedly connected with an internal cross head and a hook head.

[0006] By adopting the above technical solution, through the snap-fitting connection between the sleeve and the first wrench mechanism, and the magnetic connection between the first magnet and the second magnet at the bottom end of the inserting rod, the entire auxiliary tooling is more compact in structure and easier to assemble and disassemble, improving the convenience of use.

Users can select inner hook-shaped heads or other components of different shapes and sizes according to needs and insert them into the receiving sleeve rod. Through the meshing connection between the second tooth groove and the second external teeth on the inner hook-shaped head, stable force transmission is achieved.

[0019] Further, an inner hook-shaped head is arranged inside the receiving sleeve rod, the outer wall of the inner hook-shaped head is fixedly connected with second external teeth, and the second external teeth are adapted to the second tooth groove.

[0020] By adopting the above technical solution, by arranging an inner hook-shaped head inside the receiving sleeve rod and fixedly connecting second external teeth on the outer wall of the inner hook-shaped head, the inner hook-shaped head can be adapted to the second tooth groove on the inner wall of the receiving sleeve rod through the second external teeth to form a stable meshing connection, improving the fixing stability and firmness of the inner hook-shaped head in the receiving sleeve rod, and also ensuring the uniform dispersion of force during the transmission process, effectively avoiding deformation or damage caused by single-point force.

[0021] In summary, the main beneficial effects of the present utility model are as follows:

[0022] 1. By setting the first wrench mechanism and matching it with an inner cross head or a hook-shaped head, the whole auxiliary tooling can be applied to the replacement operation of cutter heads of various types of cutting machines, improving the versatility and practicability of the tooling. The multiple square insertion rods and multiple slots form an effective force transmission mechanism, which can reduce the force on a single insertion rod during use, thus avoiding the deformation of the insertion rod and prolonging the service life of the tooling. This magnetic adsorption connection method between the insertion rod and the slot also makes the replacement of the inner cross head or the hook-shaped head convenient and fast, reducing the user's usage cost and maintenance difficulty;

[0023] 2. By setting the second wrench mechanism, the whole auxiliary tooling can more stably connect and fix different types of cutter heads of the cutting machine, improving the adaptability and reliability of the tooling. The meshing of multiple first tooth grooves and first external teeth, and second tooth grooves and second external teeth enables the force to be evenly dispersed to each tooth, not only increasing the bearing limit, but also effectively avoiding deformation or damage caused by excessive force on a single tooth. The adsorption effect of the third magnet and the fourth magnet further enhances the fixing stability of the inner cross block or the inner hook-shaped head, and also makes the replacement process more convenient and fast, reducing the user's usage cost and maintenance difficulty.

[0032] The following will describe the embodiments of the present utility model according to its overall structure.

[0033] Embodiment 1:

[0034] An auxiliary tooling for replacing the cutter head of a cutting machine, as Figures 1 - 4 shown, includes a sleeve 1. An installation groove 2 is provided at the top of the sleeve 1. A first magnet 3 is installed at the bottom of the installation groove 2. A first wrench mechanism 5 is snap-fitted and connected inside the installation groove 2 through a clamping block 4. The first wrench mechanism 5 includes a first main rod 501. Matrix-type slots 502 are provided inside both ends of the first main rod 501. A second magnet 503 is used for magnetic attraction connection between the bottom ends of the slots 502 and the insertion rods 504. There are two groups of insertion rods 504. One ends of the two groups of insertion rods 504 are respectively fixedly connected with an inner cross head 505 and a hook-shaped head 506. The magnetic attraction connection between the matrix-type slots 502 provided inside both ends of the first main rod 501 and the insertion rods 504 not only enables the inner cross head 505 and the hook-shaped head 506 to be conveniently replaced, but also during the use process, the force transmission between multiple slots 502 and the insertion rods 504 can reduce the force received by a single insertion rod 504, effectively avoiding the deformation of the insertion rod 504, thereby improving the service life and stability of the tooling.

[0035] Refer to Figure 1 and Figure 2 , both the slots 502 and the insertion rods 504 are provided with multiple ones, and the multiple slots 502 and the insertion rods 504 are arranged in a rectangular array. The multiple slots 502 and the insertion rods 504 also improve the stability and reliability of the entire auxiliary tooling. Even if some of the insertion rods 504 or the slots 502 are worn or damaged during the use process, the other insertion rods 504 and the slots 502 can still continue to undertake the task of force transmission, ensuring the normal use of the tooling.

[0036] Refer to Figure 1 and Figure 2, one end of the sleeve 1 is provided with a clamping groove 6. There are four clamping grooves 6, and the four clamping grooves 6 are arranged in an annular and equidistant manner. The annular and equidistant arrangement of the four clamping grooves 6 also optimizes the distribution and transmission of force. During use, no matter which direction the force acts on the sleeve 1, the force can be evenly dispersed through these four clamping grooves 6 to clamp the device, avoiding deformation or damage caused by concentrated force.

[0037] The implementation principle of the present utility model is as follows: First, take out the first wrench mechanism 5 from the installation groove 2 of the sleeve 1, and then select the internal cross head 505 or the hook head 506 to disassemble the device. During the process of applying force, multiple square insertion rods 504 can form force transmission with multiple slots 502, so that the force received by a single insertion rod 504 can be reduced, avoiding the deformation of the insertion rod 504;

[0038] When replacement is required after long-term use, pull out the internal cross head 505 or the hook head 506 outward, so that the insertion rod 504 is separated from the second magnet 503, and then insert the insertion rod 504 of the new cross head 505 or hook head 506 into the inside of the slot 502 to complete the repair and replacement.

[0039] Embodiment Two:

[0040] Refer to Figure 3 and Figure 4 , a second wrench mechanism 7 is detachably connected inside the installation groove 2 through a clamping block 4. The second wrench mechanism 7 includes a second main rod 701. The second wrench mechanism 7 including the second main rod 701 provides more choices and conveniences for users. The second main rod 701 can be of different shapes, lengths or materials to meet different usage requirements and preferences.

[0041] Refer to Figure 3 and Figure 4 , one end of the second main rod 701 is fixedly connected with a receiving collar 702. The inner wall of the receiving collar 702 is provided with a first tooth groove 703. The bottom of the receiving collar 702 is fixedly connected with a third magnet 710. The third magnet 710 fixedly connected to the bottom of the receiving collar 702 further enhances the connection stability and convenience. The third magnet 710 can adsorb the internal cross block 704 to fix it more firmly inside the receiving collar 702, and it is not easy to loosen or fall off.

[0042] Refer to Figure 3 and Figure 4, inside the receiving collar 702, there is an inner cross block 704. On the outer wall of the inner cross block 704, there is a first external tooth 705 fixedly connected. The first external tooth 705 is adapted to the first tooth groove 703. This meshing connection also makes the replacement of the inner cross block 704 more convenient and fast. When the user needs to replace the new cutter head, they only need to take out the original inner cross block 704 from the receiving collar 702 and then put in the new inner cross block 704, without the need for complex disassembly and installation steps, thus improving the use efficiency and convenience of the entire auxiliary tooling.

[0043] Refer to Figure 3 and Figure 4 , at one end of the second main rod 701, there is a receiving sleeve rod 706 fixedly connected. Inside the wall of the receiving sleeve rod 706, there is a second tooth groove 707. At the bottom of the receiving sleeve rod 706, there is a fourth magnet 711 fixedly connected. The fourth magnet 711 fixedly connected to the bottom of the receiving sleeve rod 706 further enhances the connection stability and convenience. The fourth magnet 711 can adsorb the inner hook-shaped head 708 or other components, making it more firmly fixed inside the receiving sleeve rod 706 and not easily loosening or falling off.

[0044] Refer to Figure 3 and Figure 4 , inside the receiving sleeve rod 706, there is an inner hook-shaped head 708. On the outer wall of the inner hook-shaped head 708, there is a second external tooth 709 fixedly connected. The second external tooth 709 is adapted to the second tooth groove 707. When the user needs to replace different types of cutter heads, they only need to take out the original inner hook-shaped head 708 from the receiving sleeve rod 706 and then put in the new inner hook-shaped head 708. The entire replacement process does not require complex disassembly and installation steps, thus greatly improving the use efficiency and convenience of the entire auxiliary tooling.

[0045] The implementation principle of the present utility model is as follows: First, take out the second wrench mechanism 7 from the installation groove 2 of the sleeve 1, and then during the force application process, multiple first tooth grooves 703 and first external teeth 705, and second tooth grooves 707 and second external teeth 709 form meshing, so that the force can be evenly distributed to each tooth. While increasing the bearing force limit, it can reduce the force received by a single tooth and avoid deformation during use;

[0046] When replacement is needed after long-term use, take out the inner cross block 704 or the inner hook-shaped head 708 outward, and then put the new one into the inside of the receiving collar 702 or the receiving sleeve rod 706, and it is adsorbed by the third magnet 710 and the fourth magnet 711 to complete the installation.

[0047] Parts not involved in the present utility model are the same as or can adopt the prior art to implement, and will not be elaborated here too much.

[0048] Although embodiments of the present utility model have been shown and described, the specific embodiments are only interpretations of the present utility model and do not limit the utility model. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not contribute creatively to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
