[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 3 The utility model provides an embodiment: a turning and milling compound electric spindle that is convenient for tool changing, including a shaft body 1, the outer wall of the shaft body 1 is fixedly connected to a connecting ring 2, the outer wall of the connecting ring 2 is rotatably connected to a knob 7, the inner part of the knob 7 is rotatably connected to a mounting seat 3, the interior of the connecting ring 2 and the mounting seat 3 are both provided with a slide groove 4, the inner part of the knob 7 is rotatably connected to the inside of the slide groove 4, the interior of the mounting seat 3 is slidably connected to a tool 5, the outer wall of the tool 5 is provided with a mounting assembly, the mounting assembly is used to install the tool 5 inside the mounting seat 3, the outer wall of the mounting seat 3 is fixedly connected to a fixing plate 6, and the inner part of the fixing plate 6 is slidably connected to a plug plate 8 , the outer wall of the inserting plate 8 is fixedly connected to the limit rod 9, the interior of the fixed disk 6 is provided with a return spring 10, the interior of the knob 7 is fixedly connected to the limit disk 11, the interior of the limit disk 11 is provided with an arc groove 12, the outer wall of the limit rod 9 is slidably connected to the interior of the arc groove 12; the mounting assembly includes a fixing seat 22, the interior of the fixing seat 22 is fixedly connected to the outer wall of the tool 5, and the outer wall of the inserting plate 8 is slidably connected to the interior of the fixing seat 22; the outer wall of the fixing plate 6 is rotatably connected to the interior of the knob 7, one end of the return spring 10 is fixedly connected to the interior of the fixing plate 6, and the other end of the return spring 10 is fixedly connected to the outer wall of the inserting plate 8;

[0025] The tool 5 is then disassembled by rotating the knob 7 so that the limit plate 11 can be rotated. The rotation of the limit plate 11 will cause the arc groove 12 to interact with the limit rod 9, thereby driving the limit rod 9 to move. The movement of the limit rod 9 will push the insert plate 8 to slide inside the fixed plate 6, and at the same time compress the return spring 10. As the insert plate 8 gradually slides, until the insert plate 8 completely slides out of the inside of the fixed seat 22, at this time, the sliding groove 4 opened on the outer wall of the connecting ring 2 and the mounting seat 3 limits the position of the knob 7, so that it moves within a predetermined range, preventing excessive rotation or position displacement, thereby ensuring the safety and stability of the operation, so that the fixed seat 22 can slide out from the inside of the mounting seat 3, thereby achieving the effect of quickly disassembling and replacing the tool 5, which improves the convenience of the electric spindle, not only simplifies the operation steps, but also allows the operator to quickly complete the task of replacing the tool 5, thereby extending the service life of the electric spindle and improving the overall work efficiency and productivity of the equipment.

[0026] Reference Figure 1 and Figure 4, the outer wall of the shaft body 1 is provided with an upper splint 13, and the outer wall of the upper splint 13 is fixedly connected to a connecting seat 14; the inner part of the connecting seat 14 is rotatably connected to a lower splint 15, and the outer walls of the upper splint 13 and the lower splint 15 are fixedly connected to a mounting plate 16; the inner parts of the upper splint 13 and the lower splint 15 are threadedly connected to a threaded rod 17; one end of the threaded rod 17 is fixedly connected to a knob 18, and the other end of the threaded rod 17 is rotatably connected to a cushion 19, which fits the shaft body 1; the outer walls of the upper splint 13 and the lower splint 15 are fixedly connected to a connecting plate 20, and the inner part of the connecting plate 20 is threadedly connected to a fixing bolt 21;

[0027] Specifically, when the electric spindle needs to be fixed as a whole, the upper clamping plate 13 and the lower clamping plate 15 are first clamped on the surface of the shaft body 1 to ensure that the shaft body 1 can be evenly and firmly fixed to prevent movement or vibration during operation. At the same time, the fixing bolt 21 is rotated to cooperate with the connecting plate 20 to tighten the upper clamping plate 13 and the connecting seat 14, which ensures a firm connection between the upper clamping plate 13 and the connecting seat 14, thereby further enhancing the stability of the overall fixation. Then, by rotating the knob 18, the threaded rod 17 will drive the soft pad 19. The function of the soft pad 19 is to provide necessary buffering and stable support when clamping the shaft body 1. When the soft pad 19 completely clamps the shaft body 1, the fixing effect is maximized, ensuring the stability and accuracy of the electric spindle during operation. The mounting plate 16 is used to connect to the fixing parts inside the machine tool, which further enhances the firmness and reliability of the overall structure. This not only improves the stability of the electric spindle during high-speed operation, but also effectively ensures the smooth progress of its operation and reduces the negative impact that may be caused by vibration or movement.

[0028] Working principle: When the tool 5 needs to be disassembled, the limit plate 11 is driven to rotate by turning the knob 7, so that the limit plate 11 can be driven by the arc groove 12 to limit the limit rod 9, and then the limit rod 9 pushes the inserting plate 8 to slide inside the fixed plate 6, and at the same time compresses the return spring 10 until the inserting plate 8 completely slides out of the fixing seat 22, wherein the sliding groove 4 provided on the outer wall of the connecting ring 2 and the mounting seat 3 can limit the position of the knob 7, and then the tool 5 can be slid out from the inside of the mounting seat 3, thereby achieving the effect of quickly disassembling and replacing the tool 5, improving the electric The convenience of the spindle extends the service life of the electric spindle. When the electric spindle needs to be fixed as a whole, the upper clamping plate 13 and the lower clamping plate 15 are clamped on the surface of the shaft body 1, and the fixing bolts 21 are rotated to cooperate with the connecting plate 20 to fix the upper clamping plate 13 and the connecting seat 14. At the same time, the knob 18 is rotated to drive the threaded rod 17 to push the cushion 19 until the cushion 19 completely clamps the shaft body 1. The mounting plate 16 can be connected to the internal fixings of the machine tool, thereby achieving the effect of fixing the electric spindle as a whole, improving the stability of the electric spindle, and ensuring the smooth operation of the electric spindle.
