Description

Technical Field

[0001] This utility model relates to the technical field of spring shaft roller disassembly tools, and in particular to a disassembly tool for spring shaft rollers. Background Technology

[0002] In the field of spring shaft roller disassembly, in order to achieve efficient and non-destructive disassembly of spring shaft rollers and ensure the smooth progress of equipment maintenance or repair work, it is often necessary to use special disassembly tools to assist in the operation. At present, the industry mostly relies on general wrenches, pliers or simple custom tools to carry out spring shaft roller disassembly operations. In practical applications, general-purpose tools are not designed specifically for the structural characteristics of spring shaft rollers. Simple custom tools are mostly one-piece structures, and the cutting head cannot be flexibly replaced. When dealing with spring shaft rollers of different specifications, the entire tool set needs to be replaced frequently, which is cumbersome and increases operating costs. The connection structure between the main shaft and the grip body of some tools is not reasonably designed. When disassembling and applying force, the main shaft is prone to jamming or loosening, which not only affects the continuity of operation but may also pose a safety hazard due to accidental tool detachment. Therefore, improvements are needed to address the above issues. Utility Model Content

A main rod 4 is installed within the installation groove, and a reinforcing component is provided at the connection between the main rod 4 and the main body 1. The main body 1 facilitates the installation of the main rod 4; the anti-slip block 2 prevents slippage during operation; and the main rod 4 facilitates the installation of different cutting heads. The reinforcing component includes a limiting ring 3 installed at the front end of the installation groove in the main body 1, with a limiting ring 3 having an internal opening... The main rod 4 has a polygonal groove, and a connecting block 5 that matches the polygonal groove is provided inside the limiting ring 3. The connecting block 5 is installed in the middle of the main rod 4. The setting of the limiting ring 3 and the connecting block 5 facilitates the quick installation of the main rod 4. Multiple equidistant limiting grooves are opened on the outer side of the connecting block 5, and a first limiting block 6 and a second limiting block 7 are respectively provided on both sides of the connecting block 5. The upper ends of the first limiting block 6 and the second limiting block 7 are movably hinged to the front end face of the main body 1. The setting of the first limiting block 6, the second limiting block 7 and the connecting block 5 facilitates the quick assembly and disassembly of the main rod 4.

[0015] In this utility model, the first limiting block 6 and the second limiting block 7 have a connecting groove for the connecting block 5 on their adjacent surfaces. The connecting groove and the limiting groove facilitate quick disassembly of the connecting block 5, thereby preventing the connecting block 5 from getting stuck in the mounting groove due to the force on the main rod 4. Spline shafts are installed at both ends of the main rod 4, and the first cutter head 9 and the second cutter head 10 are respectively provided at both ends of the main rod 4. Spline grooves that mate with the spline shafts are opened on the adjacent surfaces of the first cutter head 9 and the second cutter head 10. The spline shaft and the spline groove facilitate quick installation of the first cutter head 9 and the second cutter head 10. The first cutter head 9 and the second cutter head 10 facilitate the assembly and disassembly of different devices. A cover plate 8 is threadedly connected to the front end face of the main body 1, and a threaded groove is opened on the rear end face of the main body 1. An extension block 11 is threadedly connected in the threaded groove. The cover plate 8 helps to protect the first limiting block 6 and the second limiting block 7 from limiting the connecting block 5. The extension block 11 prevents debris from entering the threaded groove, and the threaded groove facilitates the connection of this device to other devices. (Refer to...) Figure 6 As shown, the first cutter head 9 can be a hexagonal pyramid or other pyramidal cutter head structures, which facilitates the disassembly and assembly of spring shaft rollers with spring end grooves.

[0016] Working Principle: When using this utility model, firstly, according to the disassembly requirements of the spring shaft roller, select the appropriate first cutter head 9 or second cutter head 10. The selected cutter head is installed on the main rod 4 by engaging the splined shafts at both ends of the main rod 4 with the splined grooves on the surfaces close to the cutter head. Then, the main rod 4 with the installed cutter head is placed into the mounting groove at the front end of the main body 1. The connecting block 5 in the middle of the main rod 4 engages with the limiting ring 3 inside the mounting groove to complete the initial positioning of the main rod 4. Then, the first limiting block 6 and the second limiting block 7 on both sides of the connecting block 5 are rotated to... The connecting groove of the limiting block 7 cooperates with the limiting groove on the outside of the connecting block 5 to limit and fix the connecting block 5. Then, the cover plate 8 is connected to the front end face of the main body 1 by thread, thereby protecting the connection structure of the first limiting block 6, the second limiting block 7 and the connecting block 5. When it is necessary to extend the operating distance or connect other auxiliary devices, the extension block 11 can be removed from the threaded groove at the rear end of the main body 1, and other auxiliary devices can be connected to the device through the threaded groove. Similarly, the main rod 4 can be removed from the main body 1 by reversing the operation, and the first cutter head 9 and the second cutter head 10 can be removed from the main rod 4.
