[0002] A high-precision vertical machining center is an advanced CNC machine tool mainly used for high-precision and high-efficiency metal cutting. It combines computer numerical control technology, precision mechanical structure and automation functions, and is suitable for the mass production of complex parts or the production of parts with high precision requirements.

[0003] Existing automatic tool changers suffer from inefficiencies and sluggish movements in their existing clamping mechanism during tool changing. Most devices require complex mechanical linkages to release the clamping blocks, which not only results in slow response and extended tool changing cycles but also makes them prone to jamming due to wear on transmission components, leading to tool changing interruptions. Some semi-automatic structures even require manual intervention to release and reset the clamping blocks, severely restricting the automation level and production cycle of machining centers.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, according to Figures 1-6 As shown, an automatic tool changer for a high-precision vertical machining center includes a machine housing 1, a vertical machining center body 3 is provided inside the machine housing 1, an adjustment component 4 is provided on the outer wall of the vertical machining center body 3, and a clamping component 5 is provided on the top of the adjustment component 4.

[0026] The clamping assembly 5 includes several fixed frames 501. Each fixed frame 501 has a cylindrical block 502 on its outer wall. Each cylindrical block 502 has a push post 503 fixedly connected to its outer wall. The outer walls of the push posts 503 are connected to the inner walls of the fixed frames 501 via a through-chain connection. Each push post 503 has a wedge block 504 fixedly connected to its outer wall. Each fixed frame 501 has two sliding posts 505 symmetrically slidably connected to its inner wall. Each sliding post 505 has a spring 506 fitted onto its outer wall. Each sliding post 505 has a clamping block 507 fixedly connected to its outer wall. Each clamping block 507 has an anti-slip pad 508 fixedly connected to its outer wall. A cutter head 509 is clamped between the anti-slip pads 508. The outer walls of several cylindrical blocks 502 are in contact with a second electric push rod 510. A support frame 511 is fixedly connected to the bottom of the second electric push rod 510. The side of the two clamping blocks 507 near the wedge block 504 is a sloping structure. The sloping surface slides against the outer wall of the wedge block 504. Slider blocks are symmetrically fixedly connected to the outer wall of the wedge block 504. Sliding grooves are opened on the sloping surfaces of the two clamping blocks 507. The outer wall of the slider slides against the inner wall of the sliding groove. A support frame 511 is fixedly connected to the outer wall of the two sliding frames 405. The support frame 511 does not contact the outside of the rotating table 407.

[0027] The overall effect of embodiment 1 is as follows: the clamping assembly 5 has a significant overall effect. The second electric push rod 510 pushes the cylindrical block 502, which drives the push column 503 and the wedge block 504 to move. By utilizing the sliding cooperation between the wedge block 504 and the inclined surface of the clamping block 507, and in conjunction with the spring 506 on the sliding column 505, the clamping and releasing of the cutter head 509 can be quickly realized. The anti-slip pad 508 enhances the stability of clamping the cutter head 509 and prevents the cutter head 509 from slipping or shifting during the tool changing process. The cooperation between the slider and the sliding groove further ensures the accuracy of the clamping action, so that the clamping assembly 5 can reliably complete the picking and putting-away operation of the cutter head 509, providing a stable clamping guarantee for automatic tool changing.

[0028] Example 2, according to Figures 3-4As shown, the adjustment component 4 includes symmetrically formed sliding grooves 401 on the outer wall of the vertical machining center body 3. A movable frame 402 is slidably connected to the outer wall of the sliding grooves 401. A cylinder 403 is installed on the outer wall of the vertical machining center body 3. The output end of the cylinder 403 is fixedly connected to the bottom of the movable frame 402. A limit groove 404 is symmetrically formed on the outer wall of the movable frame 402. A sliding frame 405 is slidably connected inside the limit groove 404. A first electric push rod 406 is symmetrically installed on the outer wall of the movable frame 402. The output end of the first electric push rod 406 is fixedly connected to the outer wall of the sliding frame 405. A rotating table 407 is rotatably connected to the inner walls of the two sliding frames 405 through bearings. Several mounting slots 408 are formed on the top of each rotating table 407. A motor 409 is installed on the bottom of each of the two sliding frames 405. The output end of the motor 409 is fixedly connected to the bottom of the rotating table 407.

[0029] The overall effect of Embodiment 2 is as follows: the adjusting component 4 causes the cylinder 403 to drive the moving frame 402 to slide up and down along the slide groove 401, which can realize the flexible adjustment of the tool changing device in the vertical direction. The first electric push rod 406 pushes the sliding frame 405 to slide horizontally along the limiting groove 404, which can complete the horizontal position calibration. The motor 409 drives the rotating table 407 to rotate. Combined with the placement of the tool head 509 in the mounting groove 408, different target tool heads 509 can be accurately moved to the bottom of the vertical machining center body 3, realizing the automatic replacement of the tool head 509. This series of adjustment actions work together to realize the multi-dimensional precise adjustment of the tool changing device in space, ensuring that the target tool head 509 can accurately reach the replacement position at the bottom of the machining center body, laying a good foundation for the subsequent tool head 509 replacement operation, and greatly improving the efficiency and accuracy of automatic tool changing.

[0030] The working principle of the entire equipment is as follows: When the automatic tool changer of the high-precision vertical machining center is working, the automatic tool change is completed through the coordinated action of the adjustment component 4 and the clamping component 5. The adjustment component 4 is responsible for adjusting the tool change position. The cylinder 403 drives the moving frame 402 to slide up and down along the slide groove 401 on the outer wall of the main body 3 of the vertical machining center to realize the vertical position adjustment of the tool changer. The first electric push rod 406 pushes the sliding frame 405 to slide horizontally along the limiting groove 404 on the outer wall of the moving frame 402 to complete the horizontal position calibration. The motor 409 drives the rotating table 407 to rotate. The mounting groove 408 on its top can hold different tool heads 509. The rotation of the rotating table 407 can accurately move the target tool head 509 to the clamping position.

[0031] The clamping assembly 5 is responsible for picking up and putting down the cutter head 509. When the target cutter head 509 reaches the clamping position, the second electric push rod 510 on the support frame 511 extends and pushes the cylindrical block 502 to move. The cylindrical block 502 drives the push rod 503 and the wedge block 504 to move synchronously. Since the side of the clamping block 507 near the wedge block 504 is inclined, and the slider of the wedge block 504 slides in cooperation with the sliding groove of the inclined surface of the clamping block 507, the clamping block 507 clamps and fixes the cutter head 509 when the wedge block 504 does not move. The clamping block 507 clamps the cutter head 509 through the anti-slip pad 508. After the tool change is completed, the second electric push rod 510 pushes the wedge block 504 forward. At this time, the clamping block 507, which is slidably connected to the wedge block 504, moves to both sides. The spring 506 is compressed, which drives the slide column 505 and the clamping block 507 to move back. The clamping block 507 releases the tool head 509, completing the entire tool change process.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
