Description

Technical Field

[0001] This utility model relates to the field of rotary file technology, specifically a durable alloy rotary file head. Background Technology

[0002] Rotary files are used in conjunction with high-speed electric grinders or pneumatic tools. They are widely used in industries such as machinery, automobiles, shipbuilding, chemicals, and craft carving. They can be used to process cast iron, cast steel, carbon steel, alloy steel, stainless steel, hardened steel, copper, and aluminum.

[0003] In response, Chinese patent application number CN202220203503.9 discloses a combined carbide rotary file, including a rotary file head and a fixed rod. A connecting rod is installed at one end of the rotary file head, and a plug-in rod is installed at the end of the connecting rod away from the rotary file head. A mounting groove is formed at one end of the fixed rod. Threads are provided inside the mounting groove and on the side wall of the connecting rod, and the rotary file head is connected to the fixed rod through the threads. A first mounting hole is formed on the side wall of the plug-in rod, and a second mounting hole is formed on the side wall of the fixed rod. A fixing component is installed inside the second mounting hole, and the rotary file head and the fixed rod are locked together by the fixing component through the first and second mounting holes. A locking component is installed inside the fixing component. Through the connecting rod, plug-in rod, mounting groove, and threads, the worn rotary file head or other shaped rotary file head can be easily replaced according to the actual situation, thereby reducing resource waste and workpiece processing costs.

[0004] This rotary file allows for the assembly and disassembly of the rotary file head and the fixed rod by setting a connecting rod and a mounting groove. Damaged rotary files can be replaced individually, reducing costs. However, during installation, a fixing block needs to be inserted into the mounting hole to further secure the rotary file head. The rotary file head is connected to the fixed rod by threads, and rotation is required during installation. This makes it impossible to ensure that the fixing block and the mounting hole are precisely aligned, requiring multiple attempts. The operation is cumbersome, and the complex structure makes maintenance inconvenient.

[0005] Therefore, in order to solve the above problems, a durable alloy rotary file is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a durable carbide rotary file to solve the problems mentioned in the background section regarding existing carbide rotary files, also known as carbide high-speed assorted end mills, carbide mold end mills, etc., which are used in conjunction with high-speed electric grinders or pneumatic tools. Carbide rotary files have a wide range of applications in industries such as machinery, automotive, shipbuilding, chemical, and craft carving. Carbide rotary files can be used to process cast iron, cast steel, carbon steel, alloy steel, stainless steel, hardened steel, copper, and aluminum, among other materials.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a durable alloy rotary file head, comprising: a handle, wherein a file is mounted on the left side of the handle;

[0008] A rectangular groove is provided on the left side wall of the handle, and a guide groove is provided on the inner wall of the rectangular groove. A rectangular block is fixedly connected to the right end of the file, and a circular groove is provided on the surface of the rectangular block.

[0009] A connecting structure is installed on the inner side of the handle. The connecting structure includes a rectangular sleeve, which is movably installed inside a rectangular groove. A rectangular cavity is opened at the left end of the rectangular sleeve. A cylinder is integrally formed on the inner wall of the rectangular cavity. A magnetic sheet is fixedly connected to the front end of the cylinder. Guide blocks are fixedly connected to the upper and lower sides of the rectangular sleeve. A threaded groove is opened at the right end of the rectangular cavity. A cross-threaded rod is movably installed at the right end of the handle through a bearing. A sealing ring is adhered to the left side wall of the handle.

[0010] Preferably, the rectangular block is installed inside the rectangular cavity, and the front of the rectangular block is flush with the front of the rectangular sleeve.

[0013] Preferably, the left end of the cross-threaded rod is located inside the rectangular groove and is threadedly connected to the groove.

[0014] Preferably, the right side wall of the cross-threaded rod is flush with the right side wall of the handle.

[0015] Compared with the prior art, the advantages of this utility model are as follows: By installing a rectangular block inside a rectangular cavity, a cylinder can pass through the rectangular block via a circular groove, allowing the file to be pre-fixed on the rectangular sleeve. By rotating the cross-threaded rod, the rectangular sleeve and the rectangular block can be retracted into the handle. The rectangular slot can further limit the position of the rectangular block, ensuring the connection stability between the file and the handle. It is easy to operate, has a simple structure, and is easy to maintain.

[0016] This invention features a connecting structure. A rotating cross-threaded rod connects to a threaded groove. Rotation of the rod causes a rectangular sleeve to move to the left within the rectangular groove via a guide block and guide groove. The left end of the rectangular sleeve extends from the handle, exposing the rectangular cavity. Holding the file, the rectangular block is placed inside the rectangular cavity. The cylinder passes through the rectangular block via a groove, and the magnetic piece attracts the rectangular block, pre-fixing the file to the rectangular sleeve and effectively preventing it from falling off during installation. At this point, the front of the rectangular block is flush with the front of the rectangular sleeve. Reversing the rotation of the cross-threaded rod causes the rectangular sleeve to retract to the right into the handle. The rectangular sleeve, through the cylinder and magnetic piece, guides the rectangular block into the rectangular groove. The inner front wall of the rectangular groove then fits against the front of the rectangular block and the rectangular sleeve, further securing the rectangular block and ensuring a stable connection between the file and the handle. The sealing ring also fits the file, guaranteeing a tight seal at the connection between the handle and the file. Attached Figure Description

[0025] A durable alloy rotary file includes: a handle 1, with a file 13 mounted on the left side of the handle 1;

[0026] A rectangular groove 11 is provided on the left side wall of the handle 1, and a guide groove 12 is provided on the inner wall of the rectangular groove 11. A rectangular block 14 is fixedly connected to the right end of the file 13, and a circular groove 15 is provided on the surface of the rectangular block 14.

[0027] A connecting structure 2 is installed on the inner side of the handle 1. The connecting structure 2 includes a rectangular sleeve 21, which is movably installed inside the rectangular groove 11. A rectangular cavity 22 is opened at the left end of the rectangular sleeve 21. A cylinder 23 is integrally formed on the inner wall of the rectangular cavity 22. A magnetic sheet 24 is fixedly connected to the front end of the cylinder 23. Guide blocks 25 are fixedly connected to the upper and lower surfaces of the rectangular sleeve 21. A threaded groove 26 is opened at the right end of the rectangular cavity 22. A cross-threaded rod 27 is movably installed at the right end of the handle 1 through a bearing. A sealing ring 28 is bonded to the left side wall of the handle 1. By installing the rectangular block 14 in the rectangular cavity 22, the cylinder 23 can pass through the rectangular block 14 via the circular groove 15, so that the file 13 is pre-fixed on the rectangular sleeve 21. By rotating the cross-threaded rod 27, the rectangular sleeve 21 and the rectangular block 14 can be retracted into the handle 1. The rectangular block 14 can be further limited by the rectangular groove 11 to ensure the connection stability between the file 13 and the handle 1. It is easy to operate, has a simple structure, and is easy to maintain.

[0028] Furthermore, the rectangular block 14 is installed inside the rectangular cavity 22, and the front of the rectangular block 14 is flush with the front of the rectangular sleeve 21. When the rectangular sleeve 21 drives the rectangular block 14 to retract into the inside of the handle 1, the inner wall of the rectangular groove 11 can fit against the front of the rectangular sleeve 21 and the rectangular block 14 to further fix the rectangular block 14.

[0029] Furthermore, the cylinder 23 passes through the rectangular block 14 via the circular groove 15, and the magnetic sheet 24 is magnetically connected to the rectangular block 14. The rectangular block 14 can be pre-fixed in the rectangular sleeve 21 by the magnetic sheet 24 to prevent the file 13 from falling off during installation.

[0030] Furthermore, the guide block 25 is slidably installed on the inner side of the guide groove 12, and the guide block 25 cooperates with the guide groove 12 to guide and limit the movement of the rectangular sleeve 21 inside the rectangular groove 11.

[0031] Furthermore, the left end of the cross-threaded rod 27 is located inside the rectangular groove 11 and is threadedly connected to the threaded groove 26. Rotating the cross-threaded rod 27 can drive the rectangular sleeve 21 to move.

[0032] Furthermore, the right side wall of the cross-thread rod 27 is flush with the right side wall of the handle 1. The setting of the connection structure 2 does not change the outer surface of the handle 1, which can ensure that the handle 1 can be used for connection of existing equipment.

[0033] Working principle: When connecting, the rotatable cross-thread rod 27 is threaded to the threaded groove 26. The rotation of the cross-thread rod 27 drives the rectangular sleeve 21 to move to the left in the rectangular groove 11 through the cooperation of the guide block 25 and the guide groove 12. The left end of the rectangular sleeve 21 extends out from the inside of the handle 1, and the rectangular cavity 22 is exposed. Hold the file 13 and place the rectangular block 14 in the rectangular cavity 22. The cylinder 23 passes through the rectangular block 14 through the circular groove 15, and the magnetic piece 24 will be magnetically attracted to the rectangular block 14. The file 13 can be pre-fixed on the rectangular sleeve 21, which can effectively prevent the file 13 from falling off during installation. At this time, the front of the rectangular block 14 is flush with the front of the rectangular sleeve 21.

[0034] Rotating the cross-thread rod 27 in the opposite direction can cause the rectangular sleeve 21 to retract to the right into the handle 1. The rectangular sleeve 21 then drives the rectangular block 14 into the inner side of the rectangular groove 11 through the cylinder 23 and the magnetic piece 24. At this time, the inner front wall of the rectangular groove 11 is in contact with the front of the rectangular block 14 and the rectangular sleeve 21, which can further fix the rectangular block 14, so that the file 13 can be stably connected to the handle 1, and the sealing ring (28) can fit the file 13, which can ensure the sealing of the connection between the handle 1 and the file 13.
