Description

Technical Field

[0001] This utility model relates to the field of mechanical processing and manufacturing, and in particular to a rotary table surface grinder with a convenient adjustable fixture. Background Technology

[0002] Rotary table surface grinders with easily adjustable fixtures are key equipment for machining flat surfaces of metal, stone, and other workpieces. Their fixture adaptability, grinding accuracy, and machining efficiency directly affect the workpiece machining quality and the continuity and economy of production operations.

[0003] Traditional rotary table surface grinders have obvious drawbacks. They mostly use fixed-specification fixtures, which can only adapt to workpieces of a single size and shape. When dealing with large, hollow, or irregular workpieces, it is necessary to frequently change fixtures and repeatedly adjust the equipment. This is not only time-consuming and labor-intensive, but also prone to fluctuations in grinding accuracy due to adjustment deviations. These problems restrict their ability to meet the needs of modern machining for high efficiency, adaptability, precision, and stability, and affect production efficiency and workpiece processing quality.

[0004] Therefore, those skilled in the art have provided a frustum surface grinder with a convenient adjustable fixture to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a rotary table surface grinder with a conveniently adjustable fixture. This rotary table surface grinder integrates flexible fixture adjustment and a stable grinding transmission design, effectively solving the problems of poor fixture adaptability and unstable accuracy in traditional grinders. Through the coordinated operation of the inner and outer clamping blocks, the internal and external clamping blocks can be independently controlled and adjusted to adapt to different workpieces. The internal and external clamping or coordinated clamping can be switched according to size. The inner clamping block can also be rotated to the bottom of the rotary table to avoid large workpieces, avoiding the difficulties of clamping and unstable fixation inherent in traditional fixtures. This improves the clamping efficiency of workpieces of various shapes and specifications. The drive motor drives the drive screw, combined with bearing support, clamping joints, and guide blocks, to achieve precise grinding wheel feed. The rotating motor drives the grinding wheel to rotate at high speed, and the rotating seat assists in the rotation of the rotary table, ensuring uniform grinding and eliminating accuracy deviations. The equipment relies on a stable support structure, making it suitable for factory mass production and small-batch processing in workshops. This reduces fixture change and debugging time, improves processing efficiency, and achieves efficient and precise grinding in all scenarios, balancing quality and production efficiency.

Through the above technical solution, a stable support structure for a frustum is formed by setting a rotating seat on the bearing base and multiple connecting columns. This, combined with the inner and outer limiting cavities on the surface of the frustum, and the corresponding inner and outer clamping block telescopic devices at the bottom, allows for flexible clamping of workpieces of different specifications. For large workpieces, the inner clamping block can be rotated to the bottom of the frustum to avoid obstruction.

[0007] Furthermore, the telescopic direction of each inner clamping block telescopic device is aligned with the inner limiting cavity at the corresponding position, and each inner clamping block is inserted into the inner limiting cavity at the corresponding position.

[0010] Furthermore, limit blocks are fixedly provided on both sides of the mounting base; Through the above technical solution, this design provides a guiding basis for the subsequent movement of the mounting platform, and can work with the mounting platform components to restrict its movement direction, so as to avoid the mounting platform offset from affecting the mold feed accuracy.

[0011] Furthermore, two snap-fit ​​connectors are fixedly provided on both sides of the mounting platform, and each snap-fit ​​connector is slidably snapped onto the limiting block on the corresponding side; Through the above technical solution, this structure precisely restricts the movement direction of the mounting platform by sliding the snap-fit ​​connector and the limiting block, preventing it from deviating during lifting and lowering, and ensuring the feeding accuracy of the mold.

[0012] Furthermore, the transmission lead screw is rotatably mounted in the bearing housing at one end away from the other.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Reference Figure 1 , Figure 4 , Figure 5 This utility model provides a specific implementation method: A rotary table surface grinder with easily adjustable clamps includes a support base 1, a rotating seat 2 fixedly mounted on the support base 1, and multiple connecting posts 3 fixedly mounted on the rotating seat 2. The top of each connecting post 3 is fixedly connected to a rotary table 4. The surface of the rotary table 4 has multiple inner limiting cavities 17 and outer limiting cavities 19. Multiple inner clamping block telescopic devices 21 are fixedly mounted on the bottom of the rotary table 4. Each inner clamping block telescopic device 21 has an inner clamping block 16 rotatably mounted at its telescopic end. Multiple outer clamping block telescopic devices 20 are fixedly mounted on the bottom of the rotary table 4. Each outer clamping block telescopic device 20 has an outer clamping block fixedly mounted at its telescopic end. 18. A mounting base 11 is fixedly mounted on the bearing base 1. A drive motor 14 is fixedly mounted on the mounting base 11. A bearing seat 9 is fixedly mounted on the mounting base 11. A drive screw 8 is fixedly mounted at the output end of the drive motor 14. A drive seat 13 is threaded onto the drive screw 8. A mounting platform 6 is fixedly connected to the drive seat 13. A rotating motor 7 is fixedly mounted on the mounting platform 6. By setting the rotating seat 2 on the bearing base 1 and multiple connecting columns 3, a stable support structure for the frustum 4 is formed. This, along with the inner limiting cavity 17 and outer limiting cavity 19 on the surface of the frustum 4, and the corresponding inner clamping block extension at the bottom, completes the structure. The telescopic device 21 and the outer clamping block telescopic device 20, with the inner clamping block 16 rotating at the telescopic end of the inner clamping block telescopic device 21 and the outer clamping block 18 fixed at the telescopic end of the outer clamping block telescopic device 20, enable flexible clamping of workpieces of different specifications. For large-sized workpieces, the inner clamping block 16 can be rotated to the bottom of the frustum 4 to avoid obstruction. For irregular or hollow workpieces, the telescopic device can be independently controlled to achieve inner clamping, outer clamping, or synergistic clamping, ensuring stable workpiece clamping. At the same time, the mounting seat 11 on the bearing base 1 fixes the drive motor 14 and the bearing seat 9, and the drive screw 8 at the output end of the drive motor 14 is threaded to the drive seat 13. The transmission base 13, connected to the mounting table 6 and the rotating motor 7 on the mounting table 6, forms a stable grinding transmission system. The transmission motor 14 drives the transmission screw 8 to rotate, thereby driving the mounting table 6 to precisely lift and lower to adjust the feed of the grinding wheel 5. The bearing seat 9 ensures the stability of the screw rotation. The rotating motor 7 provides high-speed rotation power for the grinding wheel 5. In conjunction with the rotating base 2, the auxiliary rotating table 4 ensures uniform grinding of the workpiece. This fundamentally solves the problems of poor adaptability and unstable accuracy of traditional grinding machine fixtures. It eliminates the need for frequent fixture changes and adjustments, simplifies the process, improves processing efficiency and accuracy, and provides reliable conditions for grinding different workpiece surfaces.

[0018] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides another specific embodiment: Each inner clamping block telescopic device 21 has its telescopic direction aligned with the corresponding inner limiting cavity 17, and each inner clamping block 16 is inserted into the corresponding inner limiting cavity 17. This design constrains the movement trajectory of the inner clamping block 16 through the inner limiting cavity 17, preventing deviation when the inner clamping block telescopic device 21 drives the inner clamping block 16 to move, ensuring that the inner clamping block 16 stably moves towards the center of the frustum 4 to clamp the workpiece, thus improving clamping accuracy. Each outer clamping block telescopic device 20 has its telescopic direction aligned with the corresponding outer limiting cavity 19, and each outer clamping block 18 is inserted into the corresponding outer limiting cavity 19. This design constrains the movement trajectory of the outer clamping block 18 through the outer limiting cavity 19, preventing deviation when the outer clamping block telescopic device 20 drives the outer clamping block 18, ensuring that the outer clamping block 18 stably moves towards the edge of the frustum 4 to clamp the workpiece, thus improving clamping stability and accuracy in the outer clamping mode. A connecting shaft 15 is fixedly connected to the output end of the rotating motor 7, and a mold is fixedly installed at the bottom of the connecting shaft 15. 5. This structure allows the power of the rotating motor 7 to be stably transmitted to the grinding wheel 5 through the connecting shaft 15, driving the grinding wheel 5 to rotate at high speed, providing stable power for the surface grinding of the workpiece, and ensuring efficient grinding operations. Limiting blocks 10 are fixedly installed on both sides of the mounting base 11. This design provides a guiding basis for the subsequent movement of the mounting table 6, and can cooperate with the mounting table 6 components to limit its movement direction, avoiding the mounting table 6 from deviating and affecting the feed accuracy of the grinding wheel 5. Two snap-fit ​​connectors 12 are fixedly installed on both sides of the mounting table 6. Each snap-fit ​​connector 12 is slidably snapped into the limiting block 10 on the corresponding side. This structure, through the sliding cooperation between the snap-fit ​​connector 12 and the limiting block 10, precisely limits the movement direction of the mounting table 6, preventing it from deviating during lifting and lowering, and ensuring the feed accuracy of the grinding wheel 5. The transmission screw 8 is rotatably installed in the bearing seat 9 at one end away from the other. This design provides stable support for the transmission screw 8, reduces its shaking during rotation, and ensures that the transmission screw 8 drives the transmission seat 13 to move smoothly, thereby ensuring the accuracy of the feed adjustment of the grinding wheel 5.

[0019] Working principle: The operator can first adjust the fixture according to the shape and size of the workpiece to be processed. If the workpiece is large or needs to avoid the inner clamping block 16, the telescopic end of the inner clamping block telescopic device 21 can be rotated to rotate the inner clamping block 16 to below the frustum 4. Then, the workpiece is placed on the surface of the frustum 4. The bearing base 1 provides stable support for the entire equipment, and the rotating seat 2 stably supports the frustum 4 through multiple connecting columns 3. Since each inner clamping block telescopic device 21 and outer clamping block telescopic device 20 can be controlled independently, when the workpiece is irregular in shape... When the workpiece has a hollow structure or is hollow inside, the inner clamping block telescopic device 21 and the outer clamping block telescopic device 20 can be flexibly operated to work together. If it is necessary to fix the workpiece from the inside to the outside, the inner clamping block telescopic device 21 is operated to extend, which drives the inner clamping block 16 to move along the inner limiting cavity 17 towards the center of the frustum 4 and press against the inner side of the workpiece. If it is necessary to clamp the workpiece from the outside to the inside, the outer clamping block telescopic device 20 is operated to extend, which drives the outer clamping block 18 to move along the outer limiting cavity 19 towards the edge of the frustum 4 and clamp the outer side of the workpiece, thereby completing the stable fixation of the workpiece. The equipment is then started, and the drive motor 14 drives the drive screw 8 to rotate. One end of the drive screw 8 is supported by the bearing seat 9 to ensure stable rotation. Since the drive seat 13 is threaded to the drive screw 8, the drive seat 13 moves up and down along the drive screw 8, thereby driving the mounting table 6 to move synchronously. The clamping joints 12 on both sides of the mounting table 6 slide on the limit block 10 to limit the direction of movement to ensure stability, so that the grinding wheel 5 can approach the workpiece on the truncated cone 4 to achieve feed adjustment. When the grinding wheel 5 reaches the appropriate grinding position, the rotary motor 7 starts and drives the grinding wheel 5 to rotate at high speed through the connecting shaft 15 to perform surface grinding on the workpiece fixed on the truncated cone 4. During the grinding process, the rotating seat 2 can assist the truncated cone 4 to rotate so that the workpiece is ground more evenly. After grinding is completed, the rotating motor 7 stops running, and the transmission motor 14 reverses to drive the grinding wheel 5 to retract upward. Then, the inner clamping block telescopic device 21 or the outer clamping block telescopic device 20 is operated to retract, so that the inner clamping block 16 or the outer clamping block 18 is reset. If the inner clamping block 16 is below the truncated cone 4, it can be rotated back to its original position, and the operator can then remove the processed workpiece.
