[0002] The CNC machine tool spindle is a high-precision automated equipment. Nowadays, pneumatic or hydraulic pressure is used to clamp and release the tool, so that the tool changing spindle does not need to be manually replaced during the tool changing process. Currently, the tool changing spindle can automatically change the tool.

[0003] At present, when the tool changing spindle is changing the tool, the tool is limited by the tool limit plate on the equipment, and the mechanical arm is used to drive the tool changing spindle to move, so that the tool changing spindle is aligned with the tool clamping, so as to realize tool loading and replacement. However, in actual use, there may be a slight deviation in the movement accuracy of the mechanical arm. As a result, when the tool is loaded and docked, the tool is not accurately aligned with the interface position of the tool changing spindle, so that the equipment needs to be docked multiple times, thereby reducing the tool replacement efficiency of the equipment. In view of the shortcomings of the prior art, the utility model provides a tool changing spindle with tool installation positioning to solve the above problems. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The embodiment of the present application solves the problem that when the existing tool changing spindle is used, there may be slight deviations in the movement accuracy of the robot arm. As a result, when the tool is loaded and docked, the tool may not be accurately aligned with the interface position of the tool changing spindle, which requires the device to be docked multiple times, thereby reducing the tool replacement efficiency of the device.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The utility model embodiment discloses a tool changing spindle with tool installation and positioning, according to the attached Figure 1-4 As shown, it includes a tool-changing spindle body 1 and a shifting mechanism arranged on the tool-changing spindle body 1, and the shifting mechanism includes a positioning platform 2 arranged outside the tool-changing spindle body 1 and a mechanical arm bracket 3 fixedly connected to the positioning platform 2;

[0026] A tool changing positioning mechanism is provided at the bottom of the tool changing spindle body 1, and the tool changing positioning mechanism comprises a positioning plate 4 fixedly connected to the equipment frame and a Y-shaped guide frame 5 arranged on the positioning plate 4, and a plurality of groups of bearing frames 6 for bearing the tool body 7 are provided on the Y-shaped guide frame 5;

[0027] A positioning rod 201 is fixedly connected to the side of the positioning platform 2 , and the positioning rod 201 is movably engaged in the Y-shaped guide frame 5 .

[0028] Furthermore, a tool limiting ring 601 is fixedly connected to the carrier frame 6, and the tool body 7 is movably clamped in the tool limiting ring 601. The designed tool limiting ring 601 is used to provide support and limitation for the tool body 7, thereby ensuring the positioning of multiple groups of tool bodies 7 for easy replacement.

[0029] Furthermore, a connecting rod 602 is fixedly connected between the multiple sets of tool limiting rings 601 . The setting of the connecting rod 602 makes the connection between the multiple sets of tool limiting rings 601 stable, and has a good supporting effect on the tool body 7 .

[0030] Furthermore, a bottom plate 8 is fixedly connected to the positioning plate 4 , and the bottom plate 8 is provided to provide support and limitation for the bottom of the tool body 7 .

[0031] Furthermore, a screw hole 801 is provided on the base plate 8, and the internal thread of the screw hole 801 is connected to a screw rod 802. Through the design of the screw hole 801 and the screw rod 802, it is convenient to limit the shorter tool body 7 inside the carrier 6. By rotating the screw rod 802, the shorter tool body 7 can be lifted up, so that the top positions of multiple groups of tool bodies 7 are aligned, which facilitates the stable docking of the tool changing spindle body 1 and the tool body 7.

[0032] Specifically, a second reinforcing rib 803 is fixedly connected between the bottom plate 8 and the positioning plate 4, and a first reinforcing rib 603 is fixedly connected between the supporting frame 6 and the positioning plate 4.

[0034] The tool changing spindle with tool installation and positioning facilitates automatic positioning of the tool changing spindle body 1 to replace the tool body 7. During operation, the positioning platform 2 and the tool changing spindle body 1 are driven to move by the mechanical arm and the mechanical arm bracket 3. The positioning platform 2 and the positioning rod 201 are moved to the corresponding Y-shaped guide frame 5 position according to the tool body 7 to be replaced, ensuring that the positioning rod 201 is fitted with the positioning plate 4.

[0035] The tool changing spindle body 1 and the positioning platform 2 are controlled to descend by the robot arm, so that the positioning platform 2 drives the positioning rod 201 to enter the interior of the Y-shaped guide frame 5. The positioning rod 201 is guided by the Y-shaped guide frame 5, and the tool body 7 is supported and limited by the carrier frame 6. Therefore, it is limited during the descent of the tool changing spindle body 1. Finally, the tool body 7 is stably inserted into the interior of the tool changing spindle body 1 and clamped, thereby realizing a stable automatic replacement process of the tool body 7 of the tool changing spindle body 1.
