Description

Technical Field

[0001] This application relates to the field of cutting tool technology, specifically to a boring and scraping integrated cutting head. Background Technology

[0002] Connecting holes are common process holes for connecting parts in machined workpieces. They generally have structures such as through holes, through holes with front countersunk holes, through holes with back countersunk holes, and through holes with both front and back countersunk holes. In the manufacturing process, they are generally manufactured using scraper bars or boring bars. When manufacturing a scraper rod, the connection part adopts a Morse taper shank structure, which is prone to falling off during the back scraping process. Welding is usually used to prevent it from falling off. At the same time, the above structure has high requirements for the matching degree between the fitting hole and the scraper rod diameter, otherwise the inner hole is easily damaged.

[0003] When using boring bar manufacturing, due to factors such as the machining location and hole wall thickness, multiple boring bars of different lengths and specifications of the same specification are required, resulting in extremely low compatibility and significantly increased costs.

[0023] Implementation Method 1 Reference Figures 1 to 3 This embodiment, as an optional implementation of this application, discloses an integrated boring and scraping cutter head, including a handle 1. Along the axial direction of the handle 1, a threaded hole 6 coaxial with it is provided on one end face of the handle 1. At the same time, a Morse taper shank 4 is also provided at this end. A T-shaped hole 5 is provided on the Morse taper shank 4, and a connecting bolt 7 adapted to the threaded hole 6 is also provided in the T-shaped hole 5. The Morse taper shank 4 is used to connect the scraper head. Furthermore, the integrated cutter head also includes a connector 2. Along the axial direction of the cutter handle 1, a plurality of limiting strips 9 are provided on the other end face of the cutter handle 1. At the same time, along the axial direction of the connector 2, a plurality of limiting grooves 8 are provided on one end of the connector 2. The cross-sections of the limiting grooves 8 and the limiting strips 9 are set in a dovetail or T-shaped structure to ensure that the limiting grooves 8 and the limiting strips 9 are compatible. During assembly, each limiting strip 9 is inserted into each limiting groove 8, thereby achieving sliding assembly between the connector 2 and the tool holder 1; Furthermore, along the radial direction of the tool holder 1, a fastening groove 11 is provided on the outer peripheral surface of the tool holder 1, and a fastening plate 10 adapted to the fastening groove 11 is provided on the connector 2, and a fastening screw 12 for connecting the tool holder 1 is also provided on the fastening plate 10. The cooperation between the limiting groove 8 and the limiting strip 9 not only enables precise and quick assembly and disassembly of the connector 2 and the tool holder 1, but also allows the mating surfaces of the limiting groove 8 and the limiting strip 9 to limit the connection in the axial direction, thereby ensuring the stability and reliability of the connection between the connector 2 and the tool holder 1. Secondly, the fastening groove 11 and the fastening plate 10 can also fix the connector 2 to the knife handle 1, preventing radial sliding during use; Furthermore, a sliding groove 13 is provided at the other end of the connector 2. The sliding groove 13 is arranged along the radial direction of the connector 2. One end of the sliding groove 13 is fully open, and the other end is provided with an adjusting screw hole 18. The adjusting screw hole 18 penetrates the connector 2 along the radial direction of the connector 2. The integrated cutting head also includes an adjustment module, which includes an adjustment screw 17, which is fastened to the adjustment screw hole 18; a boring bar 3 is slidably inserted into the slide groove 13, and the free end of the adjustment screw 17 abuts against a section of the boring bar 3, thereby allowing the extension length of the boring bar 3 to be arbitrarily adjusted by controlling the position of the adjustment screw 17; Furthermore, a scale 19 for marking its extension length is provided on the top of the boring bar 3, and an anti-slip pad 20 is provided on the bottom surface of the boring bar 3. An anti-slip pad 20 is also provided on the bottom surface of the slide groove 13, and the two anti-slip pads 20 are tightly fitted together. Furthermore, a fastening module is also provided on the connector 2. The fastening module includes a fastening screw 12. The top of the connector 2 is also provided with a screw hole. The top of the boring bar 3 is also provided with a fixing groove 14. The fastening screw 12 is inserted into the fixing groove 14, thereby pressing the boring bar 3 against the fastening screw 12, thereby making the two anti-slip pads 20 fit tightly together, thereby preventing the boring bar 3 from sliding radially through friction, and thus ensuring its reliability after installation. Furthermore, the fastening module also includes a fastening wire 15, and the fastening screw is provided with a wire insertion hole 16. One end of the fastening wire 15 is connected to the connector 2, and the other end passes through the wire insertion hole 16 and is connected to the connector 2. The adjusting screw 17 can be fixed by tightening the steel wire 15, thereby preventing it from slipping during operation and further improving the limiting effect on the boring tool 3.

[0024] Compared with the prior art, this application controls the extension length of the boring bar through the adjustment module, thereby adjusting its working point to meet the machining requirements of the hole diameter and the mating hole; Secondly, when different specifications of boring tools are needed, they can be used through the boring head, while the tool holder and other components can continue to be used, thereby improving the overall compatibility of the tool head and reducing the operating cost of the equipment. At the same time, this application can also connect a Morse taper shank, thereby integrating a boring tool and a scraper on a single tool holder, realizing an integrated design of different tools, further improving the compatibility of the equipment and reducing the operating cost.
