Detailed implementation manners

[0022] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be construed as a limitation on the protection scope of the present invention.

[0023] Referring to Figures 1-3 , an embodiment provided by the present invention, a combined hole machining tool, includes a mounting base 1. An internal mounting groove 10 is provided inside the mounting base 1. A tool shank 5 is correspondingly arranged inside the mounting groove 10. Through the mounting groove 10, quick correspondence with the tool shank 5 can be achieved, thereby enabling quick installation operation of the tool. A tool body 7 is fixedly connected to the lower end of the tool shank 5. A connecting groove 6 is provided inside the tool shank 5, and a spring 20 is fixedly connected to the inner side of the connecting groove 6;

[0024] The other end of the spring 20 is fixedly connected to a limiting plate 19. A positioning block 18 is arranged outward at the other end of the limiting plate 19. Positioning grooves 17 are opened at both ends inside the mounting groove 10. The positioning block 18 corresponds to the positioning groove 17. Press the positioning blocks 18 at both ends of the tool shank 5 inward to make them contract inward, and then correspond the tool shank 5 with the mounting groove 10, thereby quickly installing the tool inside the mounting base 1. When the positioning block 18 passes through the position of the positioning groove 17, the internal spring 20 can make the positioning block 18 pop out outward, thereby realizing its quick positioning and clamping;

[0025] Screws 11 are threadedly connected to both ends of the mounting base 1. Handles 12 are fixedly connected to the outer ends of the screws 11. The other end of the screw 11 penetrates through the mounting base 1 and is rotatably connected to an inner push plate 16. Slide grooves 14 are opened at both ends of the positioning groove 17. When disassembling the tool shank 4, rotating the outer handle 12 can drive the screw 11 to rotate, and under the action of threaded connection, the push plate 16 can be driven to move, thereby pushing the positioning block 18 to contract inward, facilitating the staff to disassemble the tool shank 5 and improving the convenience and practicality of the device;

[0026] Sliding blocks 15 are fixedly connected to both ends of the push plate 16. The sliding blocks 15 are slidably connected inside the slide grooves 14. By providing the sliding blocks 15 and the slide grooves 14, the push plate 16 can be restricted to ensure the stable sliding of the push plate 16;

[0027] A first limit block 4 is fixedly connected to the upper end of the tool handle 5. A screw hole 2 is formed inside the first limit block 4. A first limit groove 3 is provided inside the mounting seat 1. The first limit groove 3 corresponds to the first limit block 4. A positioning bolt 13 is threadedly connected to the outside of the mounting seat 1. By making the first limit block 4 correspond to the first limit groove 3 and turning the positioning bolt 13 on the outside to correspond to the screw hole 2 inside the first limit block 4, the dual locking function can be achieved, ensuring the stability of the tool during the machining process;

[0028] Second limit blocks 9 are fixedly connected to the other two ends of the tool handle 5. Second limit grooves 8 are formed at the other two ends of the mounting groove 10. The second limit blocks 9 correspond to the second limit grooves 8. By providing the second limit blocks 9 and the second limit grooves 8, the dual positioning function can be achieved, preventing the tool from shaking during the machining process.

[0029] Working principle: When the device is in use, first select a suitable tool according to the shape of the hole and the machining environment. Then, press the positioning blocks 18 at both ends of the tool handle 5 inward to make them contract inward, and then make the tool handle 5 correspond to the mounting groove 10, so as to quickly install the tool inside the mounting seat 1. When the positioning block 18 passes through the position of the positioning groove 17, the internal spring 20 can make the positioning block 18 pop out outward, so as to achieve its quick positioning and clamping. Subsequently, turning the positioning bolt 13 on the outside can correspond to the screw hole 2 inside the first limit block 4, so as to achieve its dual locking function and ensure the stability of the tool during the machining process.
