Description

Technical Field

[0001] This utility model relates to the field of milling chuck technology, and in particular to a multi-station milling chuck for brake discs. Background Technology

[0002] In brake disc machining, the positioning accuracy and multi-station synchronous limiting capability of the chuck have a crucial impact on machining efficiency and dimensional consistency. To achieve precise and efficient multi-station milling of brake discs, a dedicated multi-station milling limiting chuck is typically required. This chuck usually includes auxiliary functional modules such as a multi-axis synchronous clamping module, an adjustable limiting mechanism, and a rigid balance support. Especially during batch milling, with the linkage of multiple tools and changes in cutting load, the dynamic stability of the chuck body and the ease of station switching directly affect the machining cycle time and product yield. Therefore, developing an integrated, high-rigidity brake disc multi-station milling limiting chuck device with rapid position changing capability has become an important direction for technological improvement.

[0003] In existing technologies, chuck devices used for multi-station milling of brake discs generally include a clamping module, a limiting mechanism, and a rigid support structure. Structurally, the chuck contains a locking sleeve for fixing the milling cutter, using mechanical clamping or hydraulic locking to secure the tool. It is also equipped with adjustable limit blocks to control the milling depth and machining range. In practical use, the limiting mechanism is usually rigidly connected to the chuck base, requiring complete disassembly for adjustment or replacement. Furthermore, its limiting components and synchronization mechanisms are mostly fixed designs, making adjustment inconvenient and lacking flexibility. Especially during multi-station synchronous machining, insufficient limiting can lead to tool displacement or asynchronous machining, severely affecting machining accuracy and safety, exhibiting significant technical defects.

[0004] However, existing milling chucks still have certain problems in practical applications. On the one hand, during grinding, the milling chuck rotates at high speed, and the limiting structure in the traditional design is insufficient, leading to displacement or asynchronous processing during high-speed rotation, which seriously affects machining accuracy and safety. On the other hand, it cannot be quickly switched to milling. These problems reduce the operating efficiency and system stability of the milling chuck, necessitating optimization in structural design. Therefore, a multi-station milling chuck with a brake disc is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-station milling chuck for brake discs, which aims to improve the problem of unstable fixed milling during processing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-station milling chuck for brake discs, comprising a clamp, a milling head disposed inside the clamp, a limit component disposed inside the clamp, a fixing component disposed at one end of the clamp, a clamping block disposed on the outer wall of the clamp, and a connecting block fixedly connected to one end of the clamp.

[0007] The limiting component includes a first locking block, one end of which is fixedly connected to the outer wall of the milling head. A limiting groove is formed inside the fixture. The outer wall of the first locking block slides inside the limiting groove. The inner wall of the first locking block slides on the outer wall of the fixture. A second locking block is fixedly connected to the inner wall of the second locking block. The outer wall of the second locking block slides inside the limiting groove. The outer wall of the first locking block slides inside the first locking block.

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

[0009] The fixing component includes a fixing block, one end of which is fixedly connected to the bottom end of the clamping block.

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

[0011] An extension block is fixedly connected to the bottom end of the clamp, the outer wall of the fixed block slides inside the extension block, and an inner groove is formed inside the extension block.

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

[0013] The extension block has an inner groove, and the bottom of the clamp is rotatably connected to a rotating column.

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

[0015] One end of the rotating column is fixedly connected to a driving column, and the outer wall of the rotating column is fixedly connected to a connecting column.

[0016] As a further description of the above technical solution:

[0017] The inner part of the second connecting column is rotatably connected to a second rotating column, and the outer wall of the second rotating column is rotatably connected to a first connecting column.

[0018] As a further description of the above technical solution:

[0019] One end of the connecting column is fixedly connected to a sliding block, and the outer wall of the sliding block slides inside the inner groove.

[0020] As a further description of the above technical solution:

[0021] A spring is fitted on the outer wall of the connecting column. One end of the spring is fixedly connected to one end of the sliding block, and the other end of the spring is fixedly connected inside the extension block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the milling head is first pushed into the fixture, and the first clamping block is pushed into the limiting groove. Then, the second clamping block is placed at one end of the limiting groove, and the clamping block is pushed into the limiting groove. The limiting groove fixes the first clamping block and the second clamping block, and the second clamping block fixes the first clamping block. The clamping block fixes the milling head inside the fixture, which achieves the effect of fixing the milling head during processing and providing precise positioning when changing the milling head. It solves the problem that the milling chuck cannot be stably fixed during milling and improves the accuracy of the excitation and demagnetization tool.

[0024] 2. In this utility model, a wrench is first used to rotate the drive column, which in turn drives the first rotating column to rotate. The first rotating column then drives the second connecting column to rotate, which in turn drives the second rotating column to rotate. The second rotating column then drives the first connecting column to move. Under the limit of the extension block, the rotational motion of the drive column is converted into the linear motion of the first connecting column, pulling the first connecting column out. The first connecting column then drives the sliding block to slide outward away from the inside of the fixed block, thereby canceling the fixation between the fixed block and the extension block. Then, the milling machine is changed. After that, the drive column is released, and the sliding block is reset under the action of the spring. This achieves the effect of quickly changing the milling machine, solves the problem of quickly changing the milling machine in the milling chuck, and improves the convenience of the excitation and demagnetization tool.

[0032] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-2 This utility model provides an embodiment of a multi-station milling chuck for brake discs, including a clamp 2 as the main frame of the chuck, with a milling head 1 and a limiting component installed inside to provide stable clamping force. The milling head 1 is provided inside the clamp 2 to directly mill the brake disc. The limiting component is provided inside the clamp 2 to stably fix the milling head 1 inside the clamp 2. A fixing component is provided at one end of the clamp 2 to fix and release the clamp 2 and the clamping block 3. The clamping block 3 is provided on the outer wall of the clamp 2 and is slidably connected to the outer wall of the clamp 2. The clamping block 2 5 cooperates with the limiting groove 6 to clamp or release the brake disc, adapting to the rapid clamping of workpieces of different sizes. A connecting block 7 is fixedly connected to one end of the clamp 2 and is used to connect to an external drive device to transmit rotational power to the clamp 2 and the milling head 1.

[0034] The limiting component includes a first locking block 4, which is fixed to the outer wall of the milling head 1 and slides into the limiting groove 6 of the fixture 2 to limit the axial displacement of the milling head 1 and prevent vibration or displacement during the machining process. One end of the first locking block 4 is fixedly connected to the outer wall of the milling head 1. The fixture 2 has a limiting groove 6 inside, which provides a sliding track for the first locking block 4 and the second locking block 5 and constrains the first locking block 4 and the second locking block 5 to prevent them from rotating out of sync. The outer wall of the first locking block 4 slides inside the limiting groove 6, and the inner wall of the clamping block 3 slides on the outer wall of the fixture 2. The inner wall of the clamping block 3 is fixedly connected to the second locking block 5, which fixes the first locking block 4 inside the limiting groove 6. In cooperation with the fixing component, the milling head 1 is stably fixed inside the fixture 2. The outer wall of the second locking block 5 slides inside the limiting groove 6, and the outer wall of the first locking block 4 slides inside the clamping block 3.

[0035] Reference Figures 3-5The fixing component includes a fixing block 8, which is fixed to the bottom end of the clamping block 3. As the core connecting component of the fixing component, it cooperates with the extension block 9 to achieve the displacement adjustment and locking functions of the clamping block 3. One end of the fixing block 8 is fixedly connected to the bottom end of the clamping block 3. The extension block 9 is fixedly connected to the bottom end of the clamping 2 and is fixed to the bottom end of the clamping 2. An inner groove 17 is formed inside the extension block 9 to provide a movement track for the sliding block 15 and support the sliding of the fixing block 8. This allows for accurate pushing and releasing of the fixing block 8 from its interior. The outer wall of the fixing block 8 slides inside the extension block 9. An inner groove 17 is provided inside the extension block 9. This groove 17, located within the extension block 9, limits the movement trajectory of the sliding block 15, preventing deviation or jamming, and also provides installation space for the spring 16. A rotating column 13 is rotatably connected to the bottom end of the clamp 2. One end of the rotating column 13 is fixed to the driving column 12, and the other end is connected to a connecting column 11, transmitting external operating force to the connecting column 11 to drive the sliding block 15. One end of the rotating column 13 is fixedly connected to the driving column 12, serving as a manual operating lever. The movement is controlled by rotating... The rotational motion triggers the displacement of the subsequent linkage mechanism. A connecting column 11 is fixedly connected to the outer wall of rotating column 13, and internally connected to rotating column 14, converting the rotational force of rotating column 13 into the oscillation of rotating column 14. Rotating column 14 is rotatably connected inside connecting column 11, rotatably connecting connecting column 11 and connecting column 10, transmitting the oscillating motion to connecting column 10, pushing sliding block 15 to slide within inner groove 17. Connecting column 10 is rotatably connected to the outer wall of rotating column 14. As the axis of motion of the sliding block 15, ensuring the accuracy of its linear displacement, the sliding block 15 is fixedly connected to one end of the connecting column 10, forming a locking or releasing state with the fixed block 8, realizing the fixing or loosening of the clamping block 3. The outer wall of the sliding block 15 slides inside the inner groove 17. The outer wall of the connecting column 10 is fitted with a spring 16 to provide elastic restoring force, ensuring that the sliding block 15 automatically returns to its position when there is no external force, maintaining the clamping state. One end of the spring 16 is fixedly connected to one end of the sliding block 15, and the other end of the spring 16 is fixedly connected inside the extension block 9.

[0036] Working principle: When using this milling chuck, first push the milling head 1 into the fixture 2, push the first chuck 4 into the limiting groove 6, then place the second chuck 5 at one end of the limiting groove 6, and then push the clamping block 3 into the limiting groove 6. The limiting groove 6 fixes the first chuck 4 and the second chuck 5, and the second chuck 5 fixes the first chuck 4. The clamping block 3 fixes the milling head 1 inside the fixture 2, achieving the effect of fixing the milling head during processing and providing precise positioning when changing the milling head.

[0037] First, use a wrench to rotate column 12, which in turn rotates column 13. Column 13 then rotates connecting column 11, which in turn rotates column 14. Column 14 then moves connecting column 10. Under the limit of extension block 9, the rotational motion of column 12 is converted into linear motion of connecting column 10. Connecting column 10 slides inward, causing sliding block 15 to slide outward away from the inside of fixed block 8. Sliding block 15 compresses spring 16, thus releasing the fixation between fixed block 8 and extension block 9. Then, the milling machine is changed. After the change is completed, release column 12. Under the rebound of spring 16, sliding block 15 is reset and pushed into the inside of fixed block 8, thus fixing fixed block 8 and extension block 9, achieving the effect of quick milling machine change.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
