[0019] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model.

[0020] Example

[0021] like Figure 1-Figure 4 As shown: a tool magazine device of a high-speed drilling and tapping center machine, comprising: a working platform 1, a fixed bracket 2 is provided on the top of the working platform 1, a moving mechanism 3 is provided inside the fixed bracket 2, a drilling and tapping body 4 is provided at one end of the moving mechanism 3, a tool magazine bracket 5 is provided above the drilling and tapping body 4, the tool magazine bracket 5 is fixedly connected to a conical bracket 6, a shell 7 is provided on one side of the conical bracket 6, a telescopic mechanism 8 is provided inside the shell 7, an adaptive clamp mechanism 9 is provided on one side of the telescopic mechanism 8, and a motor 10 is provided on one side of the shell 7. The utility model uses the shell as a protective structure and is installed on one side of the conical bracket. A telescopic mechanism is provided inside the shell, and the telescopic mechanism is rotatably connected to the adaptive clamp mechanism. The adaptive clamp mechanism includes a positioning block, a clamp, a sliding rod and a spring, which can automatically adjust the clamping mode according to different tool shapes and sizes to ensure that the tool remains in a stable clamping state, effectively solving the problems of loose clamping and accurate positioning.

[0022] It can be understood that: one end of the conical bracket 6 is fixedly connected to the tool magazine bracket 5, and the other end of the conical bracket 6 is rotatably connected to the shell 7. The shell 7 is rotatably connected to the conical bracket 6 through the motor 10, which helps to disperse mechanical stress and reduce vibration transmission, thereby further improving the working stability of the tool magazine device. The tool can be quickly and accurately rotated to the specified position when needed, thereby enhancing the overall stability and working stability of the tool magazine device.

[0023] It can be understood that: the telescopic mechanism 8 includes a base 801, a rotating shaft 802 is provided inside the base 801, a second motor 803 is provided at one end of the rotating shaft 802, the middle part of the rotating shaft 802 is rotatably connected to a moving block 805, the moving block 805 is rotatably connected to one end of an X-shaped connecting rod 804, and the other end of the X-shaped connecting rod 804 is rotatably connected to an adaptive clamp mechanism 9. Through the coordinated action of the telescopic mechanism through components such as the base, the rotating shaft, the second motor, the moving block, the X-shaped connecting rod and the adaptive clamp mechanism, the functions of free telescopic and firm clamping are realized, which brings higher flexibility, precision and reliability to the equipment.

[0024] It can be understood that: the adaptive clamp mechanism 9 includes a positioning block 901, a group of clamps 902 are slidably connected inside the positioning block 901, a sliding rod 903 is provided at one end of the group of clamps 902, a spring 904 is provided in the middle of the sliding rod 903, and one end of the spring 904 is tightly pressed against the outer side of the positioning block 901. The adaptive clamp mechanism realizes the function of automatically adjusting the clamping mode according to different tools through the coordinated action of components such as the positioning block, the clamp, the sliding rod and the spring, which significantly improves the adaptability and clamping accuracy of the tool magazine device, and can also quickly return to its original position when released, thereby improving the response speed and clamping accuracy of the adaptive clamp mechanism.

[0025] It can be understood that: one side of the positioning block 901 is rotatably connected to one end of the X-shaped connecting rod 804, one end of the X-shaped connecting rod 804 is connected to the moving block 805, the moving block 805 is rotatably connected to the rotating shaft 802, and the other end of the X-shaped connecting rod 804 is rotatably connected to one end of the base 801 parallel to the moving block 805. As a key part of the adaptive clamping mechanism, the stability and accuracy of the positioning block directly affect the clamping effect of the tool. The rotational connection design between one side of the positioning block and one end of the X-shaped connecting rod gives the entire mechanism higher flexibility and response speed. This rotational connection method allows the X-shaped connecting rod to perform precise rotational movements driven by the positioning block, realizes efficient power transmission, and avoids the loss of accuracy caused by friction and wear, thereby achieving precise linear movement.

[0026] It can be understood that: one end of the rotating shaft 802 passes through one end of the base 801, the moving block 805 and the other end of the base 801 in sequence, and is fixedly connected to the output shaft of the second motor 803. Through the ingenious connection between the rotating shaft and the base, the moving block and the second motor, stable and efficient power transmission and precise control are achieved, which improves the overall performance and work efficiency of the equipment and reduces the failure rate and maintenance cost.

[0027] The working process of the utility model is as follows: in the initial state, the drilling and tapping body is located above the working platform and is connected to the fixed bracket through a moving mechanism. The tool magazine bracket is fixed on the working platform, one end of the conical bracket is fixedly connected to the tool magazine bracket, and the other end is rotatably connected to the shell. A telescopic mechanism is provided inside the shell, and an adaptive clamp mechanism is provided on one side of the telescopic mechanism. The motor is installed on one side of the shell.

[0028] When the tool needs to be changed, the control system sends a command to the motor, which starts and drives the conical bracket to rotate relative to the housing. This action causes the adaptive clamping mechanism to align with the corresponding tool in the tool magazine.

[0029] Next, the telescopic mechanism starts to work. The rotating shaft inside the base starts to rotate under the drive of the second motor. The middle part of the rotating shaft rotates and connects to the moving block, which then starts to move. The movement of the moving block is transmitted to the adaptive clamp mechanism through the X-shaped connecting rod, causing it to telescope along a specific trajectory.

[0030] Under the action of the telescopic mechanism, the adaptive clamp mechanism gradually approaches the selected tool. The clamp inside the positioning block automatically adapts to the shape and size of the tool under the action of the sliding rod and spring, and firmly clamps the tool.

[0031] Once the tool is clamped, the telescopic mechanism continues to move the tool out of the tool magazine and send it to the drilling and tapping body. During this process, the rotation connection of the X-shaped connecting rod and the moving block ensures precise linear movement and stable mechanical properties.

[0032] When the tool reaches the drilling and tapping body, the fixture or tool holder on the drilling and tapping body takes over the tool and completes the installation of the tool. Subsequently, the drilling and tapping body performs precise drilling and tapping operations on the workpiece on the working platform driven by the moving mechanism.

[0033] After the drilling and tapping operation is completed, the tool returns to its original position in the tool magazine through the reverse workflow. The entire device returns to its initial state, waiting for the next tool change and drilling and tapping operation.

[0034] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
