Description

Technical Field

[0001] This utility model relates to the field of numerical control equipment technology, and in particular to tooling fixtures for CNC machine tools. Background Technology

[0002] CNC machine tool fixtures are used to ensure the stability and accuracy of workpieces during machining. Fixtures fix the workpiece in a specific position to prevent movement or deformation during machining. Various types of fixtures can be designed to meet different workpiece and machining requirements.

[0003] Existing tooling fixtures, such as the one proposed in application number CN202420439517.X, filed on March 7, 2024, include a worktable. The worktable's upper surface has a support slidably connected to it. A positioning block is fixedly connected to the outer wall of the support. A fixture is slidably connected to the outer wall of the positioning block. A rotating rod is rotatably connected inside the support. A worm gear is fixedly connected to one end of the rotating rod. A worm wheel is rotatably connected inside the support, meshing with the worm. A connecting rod is fixedly connected to the outer wall of the worm wheel. A rotating disk is fixedly connected to one end of the connecting rod. A locking block is slidably connected inside the rotating disk. This invention solves the problem of difficulty in changing suitable fixtures according to requirements by driving the rotating rod to rotate the worm gear. It allows for flexible fixture replacement, enabling the machine tool to adapt to the processing needs of different workpieces, improving processing flexibility, reducing adjustment time, and increasing production efficiency.

[0004] While the aforementioned patents facilitate fixture replacement, the support can only drive the fixture to move linearly to hold the workpiece; it cannot achieve the rotational movement of the fixture. This means that in some processes that require rotating the workpiece, the existing tooling fixtures cannot meet the requirements, thus limiting the scope of use of machine tools in certain special processing applications.

[0050] Combination Figures 1 to 7 As shown, the tooling fixture for CNC machine tools includes a mounting base 1, a rotating disk 2, a rotating assembly 3, a clamping assembly 4, and a flipping assembly 5.

[0051] The mounting base 1 has an internal mounting cavity 11; the rotating disk 2 is rotatably mounted on the upper part of the mounting base 1; the rotating component 3 is located in the mounting cavity 11, one end of the rotating component 3 passes through the mounting base 1 and extends to the outside of the mounting base 1 to connect with the rotating disk 2; the clamping component 4 is located on the upper part of the rotating disk 2; and the flipping component 5 is located on both sides of the clamping component 4.

[0052] The fixture features a rotating disk 2 mounted on the upper part of the mounting base 1. Under the action of the rotating component 3, the rotating component 3 can adjust the rotation angle of the rotating disk 2, thereby indirectly adjusting the rotation of the clamping component 4 and the flipping component 5. This allows the fixture to flexibly adjust the clamping angle according to actual processing needs, improving the efficiency and flexibility of CNC machine tool processing, while also ensuring stability and accuracy during processing. Through the combined action of the clamping component 4 and the flipping component 5, the clamping component 4 ensures that the workpiece will not shift during processing, improving processing accuracy. The flipping component 5 enhances the functionality of the fixture, allowing the workpiece to be flipped during processing, enabling processing at different angles and positions, thus improving processing efficiency.

[0053] Combination Figure 2As shown, the rotating assembly 3 includes: a connecting post 31, a gear ring 32, a first drive motor 33, and a first gear 34. The connecting post 31 is rotatably disposed within the mounting cavity 11, and its top end passes through the mounting base 1 and extends to the outside of the mounting base 1 to connect with the rotating disk 2; the gear ring 32 is sleeved on the connecting post 31 and is located within the mounting cavity 11; the first drive motor 33 is disposed on the upper part of the mounting base 1, and its output end passes through the mounting base 1 and extends into the mounting cavity 11; the first gear 34 is sleeved on the output end of the first drive motor 33, is located within the mounting cavity 11, and meshes with the gear ring 32.

[0054] When the angle of the rotating disk 2 needs to be adjusted, the first drive motor 33 is started. The output end of the first drive motor 33 drives the first gear 34 to rotate. The first gear 34 meshes with the gear ring 32 and transmits the rotational power to the gear ring. The gear ring 32 drives the connecting column 31 to rotate. Since the top of the connecting column is connected to the rotating disk 2, the rotating disk also rotates. By controlling the rotation direction and speed of the first drive motor 33, the angle of the rotating disk 2 can be precisely adjusted, thereby realizing the flexible adjustment of the angles of the clamping component 4 and the flipping component 5.

[0055] Combination Figure 4 , Figure 5 and Figure 6 As shown, the rotating disk 2 has an installation groove 21, and a clamping assembly 4 is detachably installed in the installation groove 21. The clamping assembly 4 includes: an installation plate 41, a locking block 42, a second drive motor 43, a second gear 44, a rack 45, and a first clamping plate 46. Mounting plate 41 is located on the upper part of rotating disk 2, and mounting plate 41 has a hollow structure; locking blocks 42 are located on the lower two sides of mounting plate 41, and locking blocks 42 are engaged in mounting groove 21; second drive motor 43 is located on the upper part of mounting plate 41, and the output end of second drive motor 43 passes through mounting plate 41 and extends into the interior of mounting plate 41; second gear 44 is sleeved on the output end of second drive motor 43, and second gear 44 is located inside mounting plate 41; rack 45 is located on both sides of second gear 44 and meshes with second gear 44, and the two racks 45 are arranged alternately; first clamping plate 46 is slidably located on the upper two sides of mounting plate 41, and first clamping plate 46 is connected to rack 45; first clamping plate 46 is provided with flipping assembly 5. Flipping assembly 5 includes: third drive motor 51, second clamping plate 52, electric push rod 53 and third clamping plate 54. The third drive motor 51 is located on one side of the first clamping plate 46. The output end of the third drive motor 51 passes through the first clamping plate 46 and is connected to the second clamping plate 52. The electric push rod 53 is located at the lower part of the second clamping plate 52. The output end of the electric push rod 53 passes through the second clamping plate 52 and is connected to the third clamping plate 54.

[0056] When the second drive motor 43 is started, the second gear 44 rotates, and the rotational motion is converted into linear motion through the rack 45, driving the first clamping plate 46 to move, thereby clamping or releasing the workpiece. When the workpiece needs to be flipped, the third drive motor 51 is started, driving the second clamping plate 52. The electric push rod 53 pushes the third clamping plate 54 through its linear motion, thereby fixing the workpiece.

[0057] To further explain, slide rails 411 are provided on both sides of the mounting plate 41, and a slider 47 is provided between the rack 45 and the first clamping plate 46. The slider 47 is slidably embedded in the slide rail 411.

[0058] The slide rail provides a precise guide path for the movement of the first clamping plate 46, ensuring that the first clamping plate moves smoothly along a predetermined straight trajectory when clamping and releasing the workpiece. The slider is embedded in the slide rail, and through cooperation with the slide rail, it further ensures the movement accuracy and stability of the first clamping plate.

[0059] Combination Figure 5 As shown, the locking block 42 has an L-shaped structure. A limiting component 6 is provided on one side of the mounting groove 21. The limiting component 6 includes a spring 61 and a limiting block 62. One end of the spring 61 is connected to the inner wall of the mounting groove 21, and the other end of the spring 61 is connected to the limiting block 62. One side of the limiting block 62 is in contact with the locking block 42.

[0060] The limiting component 6 can restrict the clamping component 4 in the mounting slot 21 so that the limiting component 6 can be detachably installed on the rotating disk 2, so that the rotating disk 2 and the mounting plate 41 can be fixedly connected under the action of the spring 61.

[0061] To further explain, the second clamping plate 52 has a U-shaped structure, which facilitates the clamping effect on the workpiece.

[0062] The working principle of this utility model is as follows:

[0063] First, fix the mounting base 1 on the CNC machine tool. Simultaneously, start the electric push rod 53 and the second drive motor 43. The output of the second drive motor 43 drives the second gear 44 to rotate. The second gear 44 meshes with the racks 45 on both sides, converting the rotational motion into linear motion. The linear motion of the racks 45 drives the first clamping plate 46 to slide along the slide rail 411, achieving clamping or releasing of the workpiece. The slide rail 411 and the slider 47 ensure smooth and precise movement of the first clamping plate 46. The electric push rod 53 pushes the third clamping plate 54 through its linear motion, achieving fixed clamping of the workpiece. When flipping is required, start the third drive motor 51. The output of the three drive motors 51 drives the second clamping plate 52 to rotate, thereby flipping the workpiece. When it is necessary to adjust the angle of the rotating disk 2, the first drive motor 33 is started. The output of the first drive motor 33 drives the first gear 34 to rotate. The first gear 34 meshes with the gear ring 32, transmitting rotational power to the gear ring 32. The gear ring 32 drives the connecting column 31 to rotate. The top of the connecting column 31 is connected to the rotating disk 2, thereby causing the rotating disk 2 to rotate. By controlling the rotation direction and speed of the first drive motor 33, the angle of the rotating disk 2 can be precisely adjusted, thereby achieving flexible adjustment of the angles of the clamping assembly 4 and the flipping assembly 5.

[0064] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
