Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a clamping claw disc. Background Art

[0002] As an important component of industrial processing equipment, the clamping disc is widely used in mechanical equipment such as lathes and milling machines to clamp and fix the workpiece. The traditional clamping disc usually consists of a base, a clamping jaw, a drive device, etc. The clamping jaws simply clamp the workpiece on its outer diameter to ensure the stability of the workpiece during processing. The design of this type of clamping disc is relatively simple. The clamping process relies on the drive device to drive the clamping jaws to achieve basic opening and closing actions, and is suitable for workpieces of regular shapes. However, this type of traditional structure can often only achieve a single clamping function, and cannot flexibly adapt to the needs of workpieces of different sizes and complex shapes. It is even more difficult to meet the higher requirements of modern industry for multifunctional and efficient clamping devices.

[0003] With the improvement of industrial processing accuracy and efficiency requirements, the limitations of existing clamping discs have gradually emerged. First, the clamping range of traditional clamping discs is fixed, which makes it difficult to adapt to the clamping needs of diversified workpieces, especially when facing irregular shapes or inner diameter processing. The lack of fine adjustment ability often leads to unstable clamping or damage to the surface of the workpiece, and the general clamping equipment does not have the possibility of rotating operation, so it is also somewhat powerless in the face of continuous processing operations. Secondly, a large amount of dust and debris will inevitably be generated during the processing, and the traditional clamping disc is usually not equipped with an effective cleaning function. These residues are easily accumulated in the clamping part or processing area, affecting the processing accuracy and increasing the complexity of equipment cleaning and maintenance. Finally, the clamping plate structure of the clamping disc generally adopts a fixed design. It takes a lot of time and manpower to maintain or replace the clamping plate, which reduces the operating efficiency of the equipment and is not conducive to high-intensity and frequent operation of modern industrial production. Based on the above problems, there is an urgent need for a new type of clamping disc that can combine versatility, fine adjustment ability and efficient maintenance to better meet the diversified needs of modern industry. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Please refer to the attached Figure 1 -Attached Figure 3 , an embodiment of the present invention provides a clamping claw plate, comprising:

[0036] Base 1, which serves as a load-bearing body and is used to ensure the stability of the structure after clamping;

[0037] The drum 2 rotates on the top of the drum 2 to cooperate with the clamped object to continue rotating;

[0038] A connecting frame 4, which is fixed to the outer wall of the drum 2 and is used to provide a moving platform;

[0039] The threaded block 7 is arranged on the top of the connecting frame 4 and is used to drive the jaw structure to move;

[0040] A driving mechanism, which is arranged on the top of the drum 2 and is used to drive the cabinet thread block 7 to continue to move;

[0041] A fine adjustment mechanism, which is arranged on the top of the threaded block 7 and is used to flexibly adjust the clamping distance according to the inner diameter of the object;

[0042] A rotating mechanism, which is arranged on the outer wall of the base 1 and is used to drive the rotating drum 2 to rotate;

[0043] The rotating mechanism includes a fixed frame 10, which is fixed to the outer wall of the base 1. The fixed frames 10 are distributed in a ring array and have rotating shafts 12 rotating inside. A motor 2 11 is arranged inside one of the fixed frames 10. The output end of the motor 2 11 is fixed to one end of the rotating shaft 12. A gear 13 is fixed to the outer wall of the rotating shaft 12. A gear ring 9 is fixedly connected to the outer wall of the rotating drum 2. The gears 13 are meshed with the gear ring 9. A fan blade 15 is fixed to one end of the rotating shaft 12. A shell 14 is fixed to the top of the fixed frame 10. The fan blade 15 is sleeved inside the shell 14. The driving mechanism includes a protective box 3. The protective box 3 is provided with motors 5 distributed in a ring array. The output ends of the motors 5 all penetrate the protective box 3 and are fixed with threaded rods 6. The threaded rods 6 rotate inside the connecting frame 4. The threaded rods 6 are threadedly connected to the threaded block 7.

[0044] Specifically, the base 1 of the clamping plate, as the bearing body, provides a stable foundation for the operation of the entire equipment, and can effectively prevent displacement or vibration caused by impact force or rotation force during operation; the rotating drum 2 is closely combined with the clamped object through the rotation function at its top, and can realize 360° free rotation of the object in the clamping state, thereby meeting the requirements of multi-angle processing or detection. The design of the connecting frame 14 makes the mobile platform closely connected with the rotating drum 2, and cooperates with the threaded block 7 set on its top to realize the linear displacement of the clamping part structure, and this displacement is controlled by the motor 15 of the driving mechanism. The motor 15 is distributed through the annular array inside the protective box 3, so that the threaded rod 6 rotates synchronously, driving the threaded block 7 to move accurately, thereby meeting the clamping requirements for objects of different sizes.

[0045] Furthermore, the setting of the fine-adjustment mechanism significantly enhances the adaptability of the equipment. Through the fine-adjustment structure on the top of the threaded block 7, the clamping distance can be flexibly adjusted according to the specific size of the inner diameter of the object. This is especially effective for objects with irregular shapes or complex geometries, ensuring that the clamping is stable and does not damage the surface of the object. The rotating mechanism is the core driving force of the entire device. Through the cooperation of the fixed frame 10 on the outer wall of the base 1 and the annularly distributed rotating shaft 12, the motor 2 11 drives the rotating shaft 12 and the gear 13 thereon to rotate synchronously, and then meshes with the toothed ring 9 on the outer wall of the rotating drum 2, driving the rotating drum 2 to complete the rotation. It is worth mentioning that the gear transmission system is designed with a gear ratio difference, so that a slight rotation can be amplified to a higher rotation frequency. This design effectively improves the processing efficiency.

[0046] In addition, when the fan blade 15 fixed at the other end of the rotating shaft 12 in the rotating mechanism rotates, it generates directional wind force through the diversion effect of the shell 14, quickly blowing away the dust and debris generated during the stamping process from the processing area, keeping the equipment and objects clean, thereby extending the life of the equipment and improving the processing accuracy. Through this multifunctional synergy, the clamping claw plate not only has stable and efficient clamping capabilities, but also can dynamically adapt to a variety of workpiece shapes and operating requirements, especially in high-intensity and diversified industrial application scenarios.

[0047] Please see attached Figure 4 The fine adjustment mechanism includes a claw frame 8, which is fixed on the top of the threaded block 7. A connecting frame 2 17 is fixed on the top of the claw frame 8. A motor 3 16 is arranged inside the connecting frame 2 17. A gear 2 18 is fixed on the output end of the motor 3 16. A rotating shaft 2 20 is rotated on the connecting frame 2 17 away from the motor 3 16. A gear 3 19 is fixed on one end of the rotating shaft 20. The gear 3 19 is meshed with the gear 2 18. A connecting rod 1 21 is fixed on the outer wall of the rotating shaft 20. A connecting rod 2 22 is rotated on one end of the connecting rod 1 21. A fixed plate 23 is rotated on one end of the connecting rod 2 22. A slider 25 is fixed on the bottom of the fixed plate 23. A slide groove 24 is opened inside the claw frame 8, and the slider 25 slides inside the slide groove 24.

[0048] Specifically, the design of the fine-tuning mechanism fully reflects the efficient response to complex mechanical requirements. Through the coordinated cooperation of a series of precision structures, it ensures that the clamping plate can accurately clamp and dynamically adjust objects of different shapes and sizes. Specifically, the claw frame 8, as the core supporting component of the fine-tuning mechanism, is fixed to the top of the threaded block 7, synchronized with its overall movement, and provides a stable foundation for fine-tuning operations. At the top of the claw frame 8, the connecting frame 2 17 plays a role of connection and bearing. The motor 3 16 configured inside it serves as a driving unit, and realizes efficient power transmission through the gear 2 18 fixed at its output end. Gear 2 18 meshes with gear 3 19 to form a precise transmission structure, thereby driving the rotating shaft 2 20 on the other side of the connecting frame 2 17 to rotate synchronously.

[0049] When the second shaft 20 rotates, the connecting rod 1 21 fixed on its outer wall moves accordingly, and the angle adjustment is realized with the second shaft 20 as the center of the circle, and the connecting rod 22 at one end of the connecting rod 1 21 further transmits the movement to the fixed plate 23, so that the fixed plate 23 can realize the flexible change of the tilt angle as needed. This dynamic adjustment can not only refine the clamping position of the clamp, but also realize the linear sliding of the clamp position through the cooperation of the slider 25 and the internal slide groove 24 of the clamp frame 8, ensuring that the clamp can smoothly and efficiently adapt to workpieces of different shapes in complex environments.

[0050] This series of motion transmission and angle adjustment greatly enhances the applicability of the clamping plate, especially for workpieces with irregular shapes or that require inner diameter clamping. The high-precision adjustment function of the fine adjustment mechanism ensures the reliability and safety of clamping. In addition, the smooth sliding of the slider 25 inside the slide 24 effectively reduces friction resistance, prolongs the service life of the equipment, and makes operation smoother. The overall design not only improves the clamping accuracy, but also significantly shortens the adjustment time, providing an efficient solution for diversified and complex industrial processing tasks, showing superior flexibility and performance stability.

[0051] Please see attached Figure 5 -Attached Figure 6 A clamping plate 26 is provided on one side of the fixed plate 23, and a connecting column 27 is fixed on the side of the clamping plate 26 close to the fixed plate 23. A limiting column 29 is fixed inside the connecting column 27, and a spring 30 is sleeved on the outer wall of the limiting column 29. One end of the spring 30 is fixed inside the connecting column 27, and a sliding column 31 is fixed on the other end of the spring 30. A ball 32 is provided on one side of the sliding column 31, and the ball 32 is engaged in the fixed plate 23 through thrust. A magnetic block 1 33 is fixed on the outer wall of the sliding column 31, and a magnetic block 2 34 is fixed inside the connecting column 27. The magnetic blocks 1 33 and 2 34 repel each other magnetically, and a groove 28 is opened on the top of the clamping plate 26.

[0052] Specifically, the matching design of the fixed plate 23 and the clamping plate 26 further enhances the adaptability of the clamping plate to the workpiece and the ease of operation. The clamping plate 26 is connected to the fixed plate 23 through a connecting column 27. The connecting column 27 is fixed on the side close to the fixed plate 23. The internal structure is exquisite, and efficient installation and disassembly are achieved. A limit column 29 is fixed inside the connecting column 27, and a spring 30 sleeved on the outer wall of the limit column 29 plays a buffering and resetting role in the structure. One end of the spring 30 is fixed inside the connecting column 27, and a sliding column 31 is fixed on the other end. When the sliding column 31 is squeezed, the spring 30 is compressed, which can effectively absorb external force and return to its original state when released, ensuring the stability and durability of the device.

[0053] The combination of the slide column 31 and the ball 32 is the key to realize the clamping function. The ball 32 is clamped inside the fixing plate 23 by the thrust action, and can smoothly complete the positioning operation when the clamping plate 26 is installed and removed, and provide sufficient locking force.

[0054] In addition, the groove 28 on the top of the clamping plate 26 provides a convenient gripping point for manual operation. When the clamping plate 26 needs to be replaced or adjusted, the connecting column 27 can be quickly separated from the fixed plate 23 by pulling the groove 28. In this process, the ball 32 is squeezed and drives the slide column 31 to move inward, while compressing the spring 30, and finally achieves a smooth separation. When reinstalling, after the ball 32 is aligned with the inner hole groove of the fixed plate 23, the elastic force of the spring 30 and the repulsive force between the magnetic block 1 33 and the magnetic block 2 34 jointly push the slide column 31, so that the ball 32 is smoothly inserted into the inner hole groove to complete the fixation.

[0055] This design not only ensures the reliability and operating efficiency of the clamping plate 26, but also significantly reduces the difficulty of manual operation through the auxiliary mechanism of the spring 30 and the magnetic force, prolongs the service life of the equipment, and adapts to the needs of high-frequency replacement and complex workpiece processing. The entire structure is compact and efficient, showing excellent practicality and engineering innovation.

[0056] Working principle: when it is necessary to continue clamping the required processing equipment, the threaded rod 6 can be driven to rotate by the motor 15, so that the threaded rod 6 drives the threaded block 7 and the claw frame 8 to move synchronously on the connecting frame 4, so as to change the position of the clamping plate 26, and then according to the specific shape and distance of each required clamping, the gear 2 18 is driven to rotate by the motor 3 16 at the corresponding position. At this time, the rotating gear 2 18 can drive the cabinet gear 3 19 to rotate in the opposite direction, and then drive the rotating shaft 20 to rotate synchronously. At this time, the connecting rod 1 21 will rotate with the rotating shaft 20 as the center of the circle, so as to drive the connecting rod 2 22 to make the same inclination angle change as the connecting rod 1 21 through the rotation of the connecting rod 1 21, so as to change The distance between the fixed plate 23 and the connecting frame 17 is adjusted, and then the position of the fixed plate 23 with the clamping plate 26 is finely adjusted, so that it can also clamp the inner diameter of some irregular shaped objects. After the clamping is completed, the object will continue to be stamped. The equipment for the stamping operation only performs displacement stamping from both sides. In order to complete the operation faster, after the first step of stamping is completed, the motor 11 can be driven to drive one of the rotating shafts 12 to start rotating the rod. At this time, the rotating rotating shaft 12 will drive the corresponding gear 13 to rotate synchronously, so that the gear 13 is meshed with the gear ring 9, so that the gear ring 9 drives the rotating drum 2 to start rotating as a whole, so that the clamped object can rotate 360°, improving The working efficiency is improved. At the same time, the dust or debris generated during stamping can also be driven by the rotating gear ring 9 to drive other rotating rod gears 13, and the rotating shafts 12 driven by each of them can rotate synchronously. Such corresponding rotating shafts 12 can all drive the fan blades 15 to rotate, thereby driving the fan blades 15 to drive the circulation of wind force, blowing the debris and dust so that they no longer adhere to the required processed objects. In addition, because the gear ring 9 and the gear 13 have different gear ratio settings, when the gear ring 9 rotates slightly, the gear 13 will be driven to rotate several times, so that the fan blades 15 can provide enough wind force. In the case of high-intensity work every day, even if the splint 26 is made of rubber, it is difficult to use it for a long time. At this time By pulling the position of the groove 28, the clamping plate 26 can drive the connecting column 27 to separate from the fixed plate 23. When the connecting column 27 is detached, the ball 32 will be squeezed first, and then drive the sliding column 31 to squeeze the spring 30. At this time, the space occupied by the spring 30 will be compressed, so that the sliding column 31 and the ball 32 can be smoothly immersed in the interior of the connecting column 27, allowing the connecting column 27 to be smoothly detached. The same steps are followed during installation, except that when the ball 32 is aligned with the hole groove in the fixed plate 23, the sliding column 31 is pushed through the restorability of the spring 30 and the repulsive force generated between the magnetic block 2 34 and the magnetic block 1 33 so that it can smoothly enter the hole groove for engagement.
