A detachable milling cutter device is located at the top front of the base plate. However, in actual use, this device requires additional tools to replace the milling cutter, resulting in low efficiency during cutter replacement and hindering high-efficiency production. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of the traditional milling cutter chuck being difficult to fix, and to propose a dual-spindle milling and turning composite quick-switching chuck structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dual-spindle milling and turning composite quick-switching chuck structure, comprising a rotating box, a fixing device installed inside the rotating box, the fixing device comprising a moving plate and a motor, multiple hinge plates hinged to the outer side of the moving plate, a connecting plate hinged to the side of the hinge plate away from the moving plate, a sliding block connected to one side of the connecting plate, a clamping block installed on one side of the sliding block, a threaded rod connected to the output shaft of the motor, and a nut embedded in the moving plate, the inner wall of the nut being threadedly connected to the outer wall of the threaded rod.

[0006] As a further description of the above technical solution:

[0007] The rotating box has multiple connecting grooves on one side, and the sliding block is slidably connected to the inner wall of the connecting groove on both sides, and the cross-section of the sliding block is I-shaped.

[0008] As a further description of the above technical solution:

[0009] The motor is fixedly installed on one side of the inner wall of the rotating box, and the end of the threaded rod away from the motor is rotatably connected to the inner wall of the rotating box.

[0010] As a further description of the above technical solution:

[0011] A mounting and dismantling device is installed on one side of the sliding block. The mounting and dismantling device includes a pressing groove and a sliding groove. Both the sliding groove and the pressing groove are opened inside the sliding block. A slider is slidably connected inside the sliding groove, and a snap-fit ​​groove is opened at the bottom of the slider. A connecting groove is opened at the bottom of the inner wall of the sliding groove. The other side of the connecting groove is connected to one side of the pressing groove. A pressing rod is slidably connected inside the pressing groove, and a snap-fit ​​block is connected to one side of the pressing rod.

[0012] As a further description of the above technical solution:

[0013] The bottom of the pressing rod has a built-in groove, and the top of the built-in groove has a sliding groove. A sliding rod is slidably connected in the sliding groove. The other end of the sliding rod is connected to the bottom of the pressing groove. A spring is sleeved on the outer wall of the sliding rod. The two ends of the spring are respectively connected to one side of the built-in groove and the bottom of the pressing groove.

[0014] As a further description of the above technical solution:

[0015] One side of the snap-fit ​​block extends out of the pressing groove through the connecting groove, and one side of the snap-fit ​​block is provided with a pressing slope. One side of the snap-fit ​​block is inserted into the snap-fit ​​groove, and one side of the slider is connected to one side of the clamping block.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] 1. In this utility model, by setting a fixing device, the threaded rod is driven to rotate by a motor, which in turn drives the moving plate to move. This causes the moving plate to move one side of the hinge plate to one side, which in turn causes the other side of the hinge plate to move the connecting plate. The connecting plate then drives the sliding block to move, which in turn causes the sliding block to move the clamping block closer together to fix the milling cutter. This avoids the trouble of manual fixing and improves the convenience of installation.

[0018] 2. In this utility model, by setting up an installation and removal device, by pressing the pressing rod, the pressing rod causes the locking block to move down, thereby causing the locking block to disengage from the locking groove, and thus the locking block loses its fixing effect on the slider. Then, the clamping block slides inward, causing the clamping block to slide out of the sliding groove, thereby removing the clamping block for replacement or repair, making the device more convenient for maintenance and replacement of the clamping block.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 4This utility model provides a technical solution: a dual-spindle milling and turning composite quick-switching chuck structure, including a rotating box 1, a fixing device 4 installed inside the rotating box 1, the fixing device 4 including a moving plate 403 and a motor 401, multiple hinge plates 404 are hinged to the outside of the moving plate 403, a connecting plate 405 is hinged to the side of the hinge plate 404 away from the moving plate 403, a sliding block 406 is connected to one side of the connecting plate 405, a clamping block 2 is installed on one side of the sliding block 406, a threaded rod 402 is connected to the output shaft of the motor 401, a nut is embedded in the moving plate 403, and the inner wall of the nut is threadedly connected to the outer wall of the threaded rod 402, multiple connecting grooves 3 are opened on one side of the rotating box 1, the two sides of the sliding block 406 are slidably connected to the inner wall of the connecting grooves 3, and the cross-section of the sliding block 406 is I-shaped, one side of the motor 401 is fixedly installed to one side of the inner wall of the rotating box 1, and the end of the threaded rod 402 away from the motor 401 is rotatably connected to one side of the inner wall of the rotating box 1.

[0026] In a specific implementation, a fixing device 4 is set up, and the output shaft of the motor 401 drives the threaded rod 402 to rotate. Then, the nut embedded in the moving plate 403 causes the threaded rod 402 to move the moving plate 403 to one side, thereby causing the moving plate 403 to move one side of the hinge plate 404. In turn, the other side of the hinge plate 404 drives the connecting plate 405 to move. The connecting plate 405 drives the sliding block 406 to move in the connecting groove 3, thereby causing the sliding block 406 to drive the clamping blocks 2 to move closer to each other to fix the milling cutter. This avoids the trouble of manual fixing. By setting four clamping blocks 2 to move simultaneously, the milling cutter can always be kept in the center when fixing it, avoiding displacement during fixing and affecting subsequent use.

[0027] A mounting / removal device 5 is installed on one side of the sliding block 406. The mounting / removal device 5 includes a pressing groove 506 and a sliding groove 501. Both the sliding groove 501 and the pressing groove 506 are formed inside the sliding block 406. A slider 503 is slidably connected inside the sliding groove 501, and a snap-fit ​​groove 502 is formed at the bottom of the slider 503. A connecting groove 504 is formed at the bottom of the inner wall of the sliding groove 501. The other side of the connecting groove 504 is connected to one side of the pressing groove 506. A pressing rod 507 is slidably connected inside the pressing groove 506. A snap-fit ​​block 505 is connected to one side of the pressing rod 507, and an internal groove is formed at the bottom of the pressing rod 507. 509, and the top of the built-in groove 509 is provided with a sliding groove 508. A sliding rod 510 is slidably connected in the sliding groove 508. The other end of the sliding rod 510 is connected to the bottom of the pressing groove 506. A spring 511 is sleeved on the outer wall of the sliding rod 510. The two ends of the spring 511 are respectively connected to one side of the built-in groove 509 and the bottom of the pressing groove 506. One side of the snap-fit ​​block 505 extends out of the pressing groove 506 through the connecting groove 504. One side of the snap-fit ​​block 505 is provided with a pressing slope. One side of the snap-fit ​​block 505 is inserted into the snap-fit ​​groove 502. One side of the slider 503 is connected to one side of the clamping block 2.

[0028] In a specific implementation, by setting up the installation and removal device 5, the sliding block 2 causes the slider 503 on the sliding block 2 to slide into the slide groove 501. The slider 503 presses against the locking block 505, causing the locking block 505 to move downwards. The locking block 505 drives the pressing rod 507 downwards, which in turn compresses the spring 511, causing the spring 511 to generate a rebound force. Then, when the locking block 505 is aligned with the locking groove 502, the rebound of the spring 511 causes the pressing rod 507 to drive the locking block 505 into the locking groove 502, thereby fixing the clamping block 2 and simplifying the installation process. The installation process is streamlined to improve efficiency. When it is necessary to replace the clamping block 2, pressing the pressing rod 507 causes the pressing rod 507 to move the locking block 505 downward, thereby causing the locking block 505 to disengage from the locking groove 502. This causes the locking block 505 to lose its fixing effect on the slider 503. Then, the clamping block 2 slides inward, causing the clamping block 2 to drive the slider 503 out of the sliding groove 501, thus removing the clamping block 2 for replacement or repair. This makes the device more convenient for maintenance and replacement of the clamping block 2. By setting the sliding rod 510 to support the spring 511, the bending of the spring 511 during compression is prevented from affecting its use.

[0029] Working principle: In use, the clamping block 2 drives the slider 503 to slide into the groove 501. Then, by pressing the locking block 505, the locking block 505 compresses the spring 511 through the pressing rod 507. After the slider 503 is installed in place, the spring 511 rebounds and drives the pressing rod 507 to reset and move. This causes the pressing rod 507 to drive the locking block 505 to insert into the locking groove 502, thereby fixing the clamping block 2. Then, the motor 401 drives the threaded rod 402 to rotate, causing the threaded rod 402 to drive the moving plate 403 with the nut embedded to move. The moving plate 403 drives one side of the hinge plate 404 to move, which in turn causes the other side of the hinge plate 404 to drive the sliding block 406 to slide in the connecting groove 3 through the connecting plate 405. This causes the clamping block 2 to clamp and fix the milling cutter, making it more convenient to fix the milling cutter.
