[0027] The utility model proposes a high-speed tool changing mechanism, comprising: a base 1;

[0028] A group of connecting plates 2 are installed on the top of the base 1. The base 1 is used to support the upper part of the structure of this mechanism, and the connecting plates 2 are used to fix the telescopic protective cover 3; two groups of telescopic protective covers 3 are installed on the inner side of the connecting plates 2, and the telescopic protective cover 3 can block the tool magazine linear rail 8 and the top of the cylinder 12 to prevent falling objects from getting stuck in the tool magazine linear rail 8 or causing damage to the cylinder 12; a cylinder rod seat 4 is also installed on the top of the base 1. When the cylinder 12 is extended and retracted, the positioning pin 1202 at one end of the cylinder rod seat 4 will slide left and right in the circular hole in the middle position of the raised block on the top of the cylinder rod seat 4, thereby improving the stability of the cylinder 12 during extension and retraction adjustment; a box 5 is also installed in the middle position of the top of the base 1, and the box 5 is used to support the motor and tool disc 9 of the upper part; a cover shell 6 is installed on the left side of the top of the box shell 5, and the cover shell 6 is used to control the control module The box body 5 is provided with a rear cover 7 on the right side, which is used to close the opening on the right side of the box body 5. After the rear cover 7 is removed, the structure inside the box body 5 can be maintained. A tool magazine linear rail 8 is also fixed on the base 1, which is used to support the sliding of the box body 5. A knife disc 9 is installed on the top of the box body 5, which is used to support the tool handle positioning block 10. When the motor on the inner side of the top of the box body 5 rotates, it can drive the knife disc 9 to rotate synchronously, so that the position of the tool can be adjusted. Several tool handle positioning blocks 10 are installed on the outside of the knife disc 9, which are used to support the tool claws 11. Two tool claws 11 are installed on the tool handle positioning blocks 10, and the tool claws 11 are used to clamp and grasp the tool. A cylinder 12 is also installed on the base 1, and the cylinder 12 is used to drive the telescopic protective cover 3 to perform telescopic adjustment.

[0029] In the embodiment of the present disclosure, Figure 3 As shown, the cutter disc 9 is a circular structure, and the tool handle positioning blocks 10 are arranged in a ring and installed on the top of the cutter disc 9 and all protrude outward. When the motor on the inner side of the top of the box body 5 rotates, it can drive the cutter disc 9 to rotate synchronously, so that the position of the tool on the tool handle positioning block 10 can be adjusted, and the tool handle positioning block 10 protruding outward can also facilitate the tool claw 11 to clamp the tool.

[0030] In the embodiment of the present disclosure, Figure 4 and Figure 5 As shown, a cylinder limit block 1201 is provided on the cylinder 12, and a positioning pin 1202 is fixed at one end of the cylinder 12. The cylinder limit block 1201 can fix the position of the cylinder 12, and when the cylinder 12 is extended or retracted, the positioning pin 1202 at one end thereof will slide left and right in the circular hole in the middle position of the raised block on the top of the cylinder rod seat 4, thereby improving the stability of the cylinder 12 during extension and retraction adjustment.

[0031] In the embodiment of the present disclosure, Figure 1 and Figure 3 As shown, the telescopic protective cover 3 is symmetrically installed on the left and right sides of the box body 5, and one side of the telescopic protective cover 3 is tightly attached to the side outer wall of the box body 5. When the box body 5 moves left and right under the support of the tool magazine linear rail 8, the telescopic protective cover 3 will also be synchronously telescoped and adjusted to ensure effective shielding of the tool magazine linear rail 8 and the top of the cylinder 12.

[0032] In the embodiment of the present disclosure, Figure 5 As shown, the locating pin 1202 is a cylindrical rod, a raised block is provided on the top of the cylinder rod seat 4, and a circular hole corresponding to the size of the locating pin 1202 is provided in the middle position of the raised block. When the cylinder 12 is extended or retracted, the locating pin 1202 at one end thereof will slide left and right in the circular hole in the middle position of the raised block on the top of the cylinder rod seat 4, thereby improving the stability of the cylinder 12 during extension and retraction adjustment.

[0033] In the embodiment of the present disclosure, Figure 1-Figure 3 and Figure 5 As shown, the telescopic protective cover 3 is located above the tool magazine linear rail 8 and the cylinder 12 on the base 1, and the telescopic protective cover 3 can be telescopically adjusted in length. The telescopic protective cover 3 can shield the tool magazine linear rail 8 and the top of the cylinder 12 to prevent fallen objects from being stuck in the tool magazine linear rail 8 or causing damage to the cylinder 12. Moreover, when the box body 5 moves left and right under the support of the tool magazine linear rail 8, the telescopic protective cover 3 will also be synchronously telescopically adjusted to ensure that the tool magazine linear rail 8 and the top of the cylinder 12 are effectively shielded.

[0034] Example 2, based on Example 1, Figure 1-Figure 5 As shown, the inner side of the telescopic protective cover 3 is supported by an iron frame, and the top surface of the telescopic protective cover 3 is covered with a layer of rubber. The iron frame inside the telescopic protective cover 3 can ensure the overall stability of the telescopic protective cover 3, and the rubber covering the top of the telescopic protective cover 3 can provide a certain degree of elasticity, which can not only rebound objects dropped from above, but also avoid deformation.

[0035] The working principle of this embodiment is as follows: during installation, the structure is first fixed inside the machining center through the base 1, and then the control module is installed in the cover 6. During use, when the motor on the inner side of the top of the box body 5 rotates, it can drive the tool disc 9 to rotate synchronously, so that the position of the tool on the tool handle positioning block 10 can be adjusted, and then the tool claw 11 on the tool handle positioning block 10 can clamp the tool and change the tool. Moreover, during the tool changing process, the box body 5 can also be displaced left and right under the support of the tool magazine linear rail 8, so as to adjust the lateral position of the tool. When the box body 5 is displaced left and right under the support of the tool magazine linear rail 8, the telescopic protective cover 3 on the inner side of the connecting plate 2 will also be synchronously telescoped and adjusted under the drive of the cylinder 12 to ensure effective shielding of the tool magazine linear rail 8 and the top of the cylinder 12. The cylinder limit block 1201 can fix the position of the cylinder 12, and the air cylinder 12 can be used to fix the position of the cylinder 12. When the cylinder 12 is extended or retracted, the locating pin 1202 at one end thereof will slide left and right in the circular hole in the middle position of the raised block on the top of the cylinder rod seat 4, thereby improving the stability of the cylinder 12 during extension and retraction adjustment. The structure inside the box body 5 can be maintained by removing the rear cover 7 at a later stage. The automatic tool changing system is integrated into the electric spindle, and the tool changing mechanism is driven by the control system instructions to realize rapid replacement of the tool. This process reduces manual intervention and downtime, and significantly improves processing efficiency and production flexibility. This mechanism adopts advanced servo motor drive to ensure fast and accurate tool changing. Through the precise positioning system, the high-speed tool changing mechanism can realize precise positioning of the tool, reducing the processing error caused by tool changing. In addition, it is also equipped with an automatic tool recognition system, which can automatically identify the type and status of the tool, further improving the level of automation and processing efficiency.
