Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, specifically to a cutting tool for flange processing. Background Technology

[0002] With the continuous development of industrial manufacturing technology, especially the popularization of CNC machining technology, the requirements for precision, efficiency, and flexibility in the machining field are gradually increasing. Flange machining, as an important machining process, is widely used in the manufacture of connecting components in industries such as machinery, aerospace, and shipbuilding. Flanges are typically used to connect pipes, valves, pumps, and other equipment, and their machining accuracy directly affects the sealing performance and stability of the equipment. Therefore, the tool design and tool changing system for flange machining must possess high precision, rapid response, and flexibility to meet the demands of efficient and precise production.

[0003] However, in existing flange processing, the movement, loading, and switching of tool sets usually rely on complex mechanical devices, and different tool configurations often require complex manual adjustments or human intervention, which increases the complexity of operation and the risk of human error. Utility Model Content

Users can flexibly configure suitable tool types and models according to actual machining requirements, thereby improving the adaptability and flexibility of the system.

[0006] Preferably, each machining tool set includes a base plate, a tool holder, and a telescopic rod. A sliding shaft is located at the rear end of the base plate, with tapped outer end faces. The rear end of the sliding shaft extends into an elongated hole in the center of the back plate and is secured with a nut. The tool holder is movably mounted to the inner side of the base plate via a pin, and has a slot for holding a turning tool or milling cutter. The movable mounting design allows the tool holder to be moved or adjusted as needed. This movable mounting design enables quick tool changes according to machining requirements, ensuring tool flexibility in different machining tasks. It also facilitates tool flipping or retrieval, optimizing tool changing efficiency. Due to the tool slot and movable mounting design, tool type and specifications can be adjusted or replaced according to specific needs. For example, different types of turning tools and milling cutters can be quickly adapted and placed in the tool holder to meet different machining process requirements. This design improves the system's versatility and adaptability.

[0007] Preferably, the telescopic rod is an electrically or pneumatically operated telescopic structure. The bottom end of the telescopic rod is hinged to the base plate, and the piston rod end of the telescopic rod is hinged to the tool holder. The tool holder moves with the telescopic rod, performing a flipping motion to retrieve the tool. The electrically or pneumatically driven telescopic rod can provide sufficient torque to support the tool holder in completing the flipping motion, adapting to the needs of different machining tasks.

Due to the fit between the slide shaft and the U-shaped groove, the toothed plate can slide smoothly on the slide shaft, avoiding jamming or obstruction caused by friction or improper structure. Furthermore, the fit between the U-shaped groove and the slide shaft simplifies the installation and removal of the toothed plate. Assemblers only need to align the toothed plate with the slide shaft and install it in place, without requiring complex docking or adjustment steps.

[0011] Preferably, the gear assembly is mounted inside the back plate, and the number of gear assemblies matches the number of gear plates. The gear assemblies mesh with the gear plates, causing multiple machining tool sets to move along the long slot. Through the meshing of the rack and gear assemblies, stable translation of multiple machining tool sets along the long hole is achieved.

[0026] Please see Figure 1 This utility model provides a technical solution: a flange processing tool, which is configured on the tool changing system or tool holder of a lathe or milling machine. The tool includes a back plate 1 and multiple processing tool groups 2 arranged in combination on the back plate 1.

[0027] Example 1: Please refer to Figures 1-2 In this embodiment, the back plate 1 is an angle steel structure with an elongated hole at the center of its end. Multiple processing tool sets 2 are located on the front side of the back plate 1. The multiple processing tool sets 2 have the same structure but different sizes, models and types. The multiple processing tool sets 2 can be combined and installed and are easy to adjust. The tools can be flexibly selected according to different processing needs. Users can flexibly configure suitable tool types and models according to actual processing needs, which improves the adaptability and flexibility of the system.

[0028] In this embodiment, each machining tool set 2 includes a base plate 201, a tool holder 202, and a telescopic rod 203. A sliding shaft 3 is provided at the rear end of the base plate 201. The outer end face of the sliding shaft 3 is tapped, and the rear end of the sliding shaft 3 extends into an elongated hole in the center of the back plate 1 and is locked with a nut. The tool holder 202 is movably mounted to the inner side of the base plate 201 via a pin, and has a groove for holding a turning tool or milling cutter. The tool holder 202's movable mounting to the inner side of the base plate 201 allows the tool holder to move or adjust as needed. This movable mounting design allows for quick tool changes according to machining requirements, ensuring the flexibility of the tool in different machining tasks. It also facilitates tool flipping or tool retrieval, optimizing tool changing efficiency. Due to the tool groove and movable mounting design, the tool type and specifications can be adjusted or replaced according to specific needs. For example, different types of turning tools and milling cutters can be quickly adapted and placed in the tool holder 202 to adapt to different machining process requirements. This design improves the system's versatility and adaptability.

[0029] In this embodiment, the telescopic rod 203 is an electrically or pneumatically telescopic structure. The bottom end of the telescopic rod 203 is hinged to the base plate 201, and the piston rod end of the telescopic rod 203 is hinged to the tool holder 202. The tool holder 202 moves with the telescopic rod 203 and performs a flipping motion to retrieve the tool. The electrically or pneumatically driven telescopic rod 203 can provide sufficient torque to support the tool holder in completing the flipping motion, adapting to the needs of different machining tasks. Whether it's high-speed tool changing or retrieving and placing different types of tools, the telescopic rod 203 can execute the flipping motion through precise control, greatly improving the system's flexibility and adaptability.

[0030] Example 2: Please refer to Figures 3-4 A drive unit is located on the rear side of the back plate 1. This drive unit is used to move multiple machining tool sets 2 along the elongated hole to switch the tool mounting position. The drive unit includes a toothed plate 4 and a gear assembly 5. U-shaped grooves are provided on both sides of the lower end of the toothed plate 4, and a rack is positioned between the two U-shaped grooves. The inner diameter of the U-shaped groove matches the outer diameter of the rear end of the sliding shaft 3, ensuring that the toothed plate 4 can be smoothly installed on the sliding shaft 3. Due to the cooperation between the sliding shaft 3 and the U-shaped groove, the toothed plate 4 can slide smoothly on the sliding shaft 3, avoiding jamming or obstruction caused by friction or improper structure. Furthermore, the cooperation between the U-shaped groove and the sliding shaft 3 makes the installation and disassembly of the toothed plate 4 much simpler. Assemblers only need to align the toothed plate 4 with the sliding shaft 3 and install it in place, without requiring complex docking or adjustment steps.

[0031] In this embodiment, the gear assembly 5 is mounted inside the back plate 1, and the number of gear assemblies 5 is the same as the number of toothed plates 4. The gear assembly 5 meshes with the toothed plates 4, causing multiple machining tool sets 2 to move along the long slot. Through the meshing of the rack and gear assembly 5, the stable translation of multiple machining tool sets 2 along the long hole is achieved. The tooth profile design of the rack allows the tool sets to maintain consistent accuracy during movement, avoiding deviation or inaccuracy during tool changing, and improving the overall accuracy and stability of the system.
