Detailed Implementation

[0016] 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.

[0017] Example 1:

[0018] The rotary quick clamping device provided by this utility model includes a base 1, a first connecting seat 2 and a second connecting seat 3. The first connecting seat 2 is movably connected to a gripper 5 via a first shaft 4. The second connecting seat 3 is movably mounted with a second shaft 6. The second shaft 6 has a screw hole 7, and an adjusting screw 8 is fixedly installed in the screw hole 7. A knob 9 is fixedly installed at one end of the adjusting screw 8, and an optical shaft 10 is provided at the other end of the adjusting screw 8. The gripper 5 has a connecting ear 11, and a third connecting seat 13 is movably installed in the connecting ear 11 via a third shaft 12. The third connecting seat 13 is fixedly connected to the optical shaft 10 through a through hole 14. Two mounting holes 15 are provided on the diagonal of the base 1. The surface of the knob 9 has anti-slip texture 16. The base 1 and the gripper 5 are both made of stainless steel. The first shaft 4, the second shaft 6 and the third shaft 12 are all provided with fixing grooves 17, and a retaining ring 18 is fixedly installed in the fixing grooves 17.

[0019] With the above technical solution, during use, the base 1 is fixed on the worktable, and the adjusting screw 8 is rotated by the knob 9, which drives the gripper 5 to swing, thereby quickly clamping or releasing the product. Specifically, the other end of the adjusting screw 8 is provided with a light shaft 10, which is fixedly installed in the through hole 14 of the third connecting seat 13. The light shaft 10 can rotate freely in the through hole 14. The third connecting seat 13 is movably connected to the connecting ear 11 through the third shaft 12. When the adjusting screw 8 rotates, the screw hole 7 of the second shaft 6 forces the adjusting screw 8 to move linearly, thereby driving the gripper 5 to swing. The screw hole 7 is located on the second shaft 6 to facilitate following the deflection of the adjusting screw 8 and ensure smooth adjustment. This device, which drives the screw to move by rotating the knob 9, thereby driving the gripper 5 to move linearly to quickly clamp or release the product, solves the problems of complex structure and inconvenient adjustment of traditional clamping devices.

[0020] Example 2:

[0021] In this embodiment, the base 1 is provided with a first connecting seat 2 and a second connecting seat 3. The first connecting seat 2 is movably connected to a gripper 5 via a first shaft 4. The gripper 5 can swing freely around the first shaft 4 to achieve clamping or releasing actions. The second connecting seat 3 is movably mounted with a second shaft 6. The second shaft 6 is provided with a screw hole 7, and an adjusting screw 8 is fixedly installed in the screw hole 7. A knob 9 is fixedly installed at one end of the adjusting screw 8, and the operator can control the entire clamping process by rotating the knob 9. The other end of the adjusting screw 8 is provided with a smooth optical axis 10, which facilitates movement in conjunction with other components.

[0022] The gripper 5 is provided with a connecting ear 11, and a third connecting seat 13 is movably mounted on the connecting ear 11 via a third shaft 12. The third connecting seat 13 is provided with a through hole 14, which is fixedly connected to the optical axis 10 of the adjusting screw 8. The optical axis 10 can rotate freely within the through hole 14 while maintaining a fixed positional relationship with the third connecting seat 13. When the knob 9 is rotated, the adjusting screw 8 rotates accordingly. Since the screw hole 7 is located on the second shaft 6, the adjusting screw 8 produces linear movement under the constraint of the screw hole 7. The linear movement is transmitted to the third connecting seat 13 via the optical axis 10, and the third connecting seat 13 drives the connecting ear 11 of the gripper 5 via the third shaft 12, causing the gripper 5 to swing around the first shaft 4.

[0023] In this embodiment, the swing angle of the gripper 5 is determined by the linear displacement of the adjusting screw 8. When the knob 9 is rotated, the linear movement of the adjusting screw 8 is directly converted into the clamping or loosening action of the gripper 5. Since the screw hole 7 is located on the second shaft 6, the second shaft 6 can automatically adjust its position according to the deflection angle of the adjusting screw 8, ensuring a smooth and unobstructed adjustment process. The gripper 5 is movably connected by multiple shafts, resulting in a uniform distribution of clamping force and a stable and reliable clamping process.

[0024] The entire device achieves rapid clamping via manual rotation of knob 9, requiring no external power source. The linear movement of adjusting screw 8 precisely controls the swing range of gripper 5, preventing fluctuations in clamping force. The multi-axis movable connection design simplifies the structure and reduces frictional losses between components. This embodiment is suitable for various manual clamping scenarios, offering simple operation, high adjustment accuracy, and solving the problems of complex structure and cumbersome operation associated with traditional clamping devices.

[0025] Example 3:

[0026] In this embodiment, the base 1 serves as the supporting foundation for the overall structure. It has two mounting holes 15 on its diagonal, which are used to fix the base 1 to the workbench. The diagonal arrangement improves the installation stability of the base 1. The base 1 has a first connecting seat 2 and a second connecting seat 3. The first connecting seat 2 is movably connected to a gripper 5 via a first shaft 4. The gripper 5 can swing freely around the first shaft 4, allowing for flexible adjustment of the clamping action. The second connecting seat 3 is movably mounted with a second shaft 6. The second shaft 6 has a screw hole 7, and an adjusting screw 8 is fixedly installed in the screw hole 7. A knob 9 is fixedly installed at one end of the adjusting screw 8, and an optical axis 10 is provided at the other end. The optical axis 10 is fixedly connected to the through hole 14 of the third connecting seat 13, ensuring that the optical axis 10 can rotate freely within the through hole 14 and avoiding jamming.

[0027] During use, the operator rotates the knob 9 to drive the adjusting screw 8 to rotate. The adjusting screw 8 moves linearly within the screw hole 7 of the second shaft 6, thereby driving the optical axis 10 to move back and forth. The optical axis 10 is fixedly connected to the third connecting seat 13, which is movably connected to the connecting ear 11 of the gripper 5 via the third shaft 12. When the optical axis 10 moves, the third connecting seat 13 moves accordingly, thereby driving the gripper 5 to swing around the first shaft 4, achieving rapid clamping or releasing of the product. The swing angle and clamping force of the gripper 5 can be precisely controlled by rotating the knob 9 to ensure a smooth and reliable clamping process.

[0028] In this embodiment, the diagonal mounting holes 15 of the base 1 enhance the stability of the overall structure, preventing the base 1 from shifting or loosening during operation. The optimized layout of the first connecting seat 2 and the second connecting seat 3 improves the force transmission path, resulting in a uniform distribution of clamping force and reducing local stress concentration. The adjusting screw 8 engages with the screw hole 7 of the second shaft 6, allowing the adjusting screw 8 to move smoothly during rotation, avoiding the adjustment difficulties commonly found in traditional clamping devices. The gripper 5 achieves flexible swinging through a multi-axis connection, adapting to the clamping needs of products with different shapes and sizes.

[0029] The operation of the knob-9 quick clamping device is simple and intuitive. Users only need to rotate knob 9 to clamp or release, without complicated steps or additional tools. The device's compact design reduces the number of parts, lowering manufacturing costs and maintenance difficulty. The diagonal arrangement of the mounting holes 15 on the base 1 further enhances the device's rigidity, making it suitable for high-precision machining environments. Overall, this embodiment achieves efficient and stable clamping functionality through optimized connection methods and mounting structures, solving the problems of inconvenient adjustment and large clamping force fluctuations in traditional clamping devices.

[0030] Example 4:

[0031] In this embodiment, the knob 9 has an anti-slip texture 16 on its surface. This texture increases the friction between the knob 9 and the operator's hand, effectively improving the grip and preventing slippage. The anti-slip texture 16 is designed based on ergonomic principles. During rotation, the torque applied by the hand is evenly distributed through the texture, avoiding localized pressure concentration and reducing hand fatigue. Simultaneously, the texture structure guides the hand to naturally conform to the surface of the knob 9, enhancing operational stability and ensuring that it will not accidentally slip during high-speed or high-load rotation. This design is suitable not only for normal working environments but also for maintaining a reliable grip in wet or oily conditions, improving the overall safety and operational efficiency of the clamping device.

[0032] During device operation, the operator holds and rotates the knob 9, causing the adjusting screw 8 to rotate. The adjusting screw 8 engages with the screw hole 7 of the second shaft 6. Since the screw hole 7 is fixed to the second shaft 6, the rotational motion of the adjusting screw 8 is converted into linear movement. This linear movement is transmitted to the third connecting seat 13 via the optical axis 10 at the other end of the adjusting screw 8. The optical axis 10 is fixedly connected to the through hole 14 of the third connecting seat 13, allowing the optical axis 10 to rotate freely within the through hole 14 without jamming. The third connecting seat 13 is movably connected to the connecting lug 11 of the gripper 5 via the third shaft 12, thereby driving the gripper 5 to swing around the first shaft 4, achieving rapid clamping or releasing of the product. The anti-slip texture 16 ensures precise control of the rotational motion during this process, preventing adjustment errors caused by hand slippage and improving the stability and repeatability of the clamping force.

[0033] The geometry and distribution of the anti-slip texture 16 are optimized to match the curved contours of the knob 9, ensuring a consistent anti-slip effect at different rotation angles. The texture depth and spacing are designed with the elasticity and friction characteristics of hand skin in mind, generating sufficient resistance during rotation to prevent slippage without causing discomfort. This design allows for efficient operation without additional tools or complex structures, simplifying the maintenance and use of the clamping device. Through the application of the anti-slip texture 16, the knob 9 quick-clamping device demonstrates higher reliability and user-friendliness in manual operation scenarios, solving the inefficiency problem caused by the inconvenience of traditional clamping devices.

[0034] In practical applications, the introduction of the anti-slip texture 16 further enhances the adaptability of the device, enabling it to maintain excellent performance in various industrial environments. For example, when frequently adjusting clamping positions on assembly lines, the anti-slip texture 16 ensures that operators can quickly and accurately complete rotational movements, reducing production interruptions caused by slippage. Furthermore, the durable design of the anti-slip texture 16 allows it to maintain functionality even after long-term use, eliminating the need for frequent component replacements and reducing maintenance costs. Overall, the anti-slip texture 16 not only enhances the practical value of the knob 9 but also promotes the development of clamping devices in the field of manual clamping through simple yet effective mechanical improvements, meeting the demand for high-precision, easy-to-operate equipment.

[0035] Example 5:

[0036] In this embodiment, both the base 1 and the gripper 5 are made of stainless steel, a material choice that significantly enhances the rigidity of the overall structure. Stainless steel possesses excellent mechanical properties, capable of withstanding high clamping forces without deformation, ensuring the device remains stable during long-term use. The base 1 is provided with a first connecting seat 2 and a second connecting seat 3. The first connecting seat 2 is movably connected to the gripper 5 via a first shaft 4, allowing the gripper 5 to swing freely around the first shaft 4. The second connecting seat 3 is movably mounted with a second shaft 6, which has a screw hole 7. An adjusting screw 8 is fixedly installed in the screw hole 7, with a knob 9 fixedly connected to one end of the adjusting screw 8 and an optical axis 10 at the other end. The gripper 5 is provided with a connecting ear 11, which is movably connected to a third connecting seat 13 via a third shaft 12. The third connecting seat 13 is fixedly connected to the optical axis 10 via a through hole 14, allowing the optical axis 10 to rotate freely within the through hole 14, ensuring smooth and unobstructed adjustment.

[0037] When the operator rotates knob 9, adjusting screw 8 rotates accordingly. Since screw hole 7 is located on the second shaft 6, adjusting screw 8 moves linearly under the constraint of screw hole 7. This linear movement is transmitted to the third connecting seat 13 via optical shaft 10, which in turn drives the gripper 5 to swing around the first shaft 4, achieving rapid clamping or releasing of the product. The use of stainless steel not only improves the strength of the base 1 and gripper 5 but also enhances wear resistance and corrosion resistance, enabling the device to operate reliably in harsh working environments. The overall structure is compact and easy to operate, achieving precise clamping force control without the need for a complex external drive system.

[0038] In this embodiment, the rigidity advantage of stainless steel is evident during the clamping process. The gripper 5 is not easily bent or deformed under force, thus ensuring the uniform distribution and stability of the clamping force. The base 1, as a supporting component, is made of stainless steel, allowing it to be firmly fixed to the worktable and withstand repeated clamping operations without fatigue damage. The swinging motion of the gripper 5 is achieved through movable connecting parts; the durability of stainless steel ensures the long-term reliability of these connection points and reduces maintenance requirements. Furthermore, the linear movement of the adjusting screw 8 is coordinated with the swinging motion of the gripper 5, allowing the operator to clamp or release the gripper with only a slight rotation of the knob 9, without the need for additional tools or complex procedures.

[0039] The overall design of the device fully utilizes the properties of stainless steel, not only solving the problems of complex structure and inconvenient adjustment in traditional clamping devices, but also optimizing performance by increasing rigidity. In manual operation scenarios, the device can respond quickly, provide stable clamping force, and avoid fluctuations, making it suitable for a variety of industrial applications. The use of stainless steel further extends the device's service life, reduces long-term operating costs, while maintaining its lightweight and ease of operation.

[0040] Example 6:

[0041] In this embodiment, the base 1 is fixedly installed on the surface of the workbench. The base 1 has a first connecting seat 2 and a second connecting seat 3. The first connecting seat 2 is movably connected to the gripper 5 through a first shaft 4. The second connecting seat 3 is movably installed with a second shaft 6. The second shaft 6 has a screw hole 7, and an adjusting screw 8 is fixedly installed in the screw hole 7. A knob 9 is fixedly installed at one end of the adjusting screw 8, and an optical axis 10 is provided at the other end of the adjusting screw 8. The gripper 5 has a connecting lug 11, and a third connecting seat 13 is movably installed in the connecting lug 11 through a third shaft 12. The third connecting seat 13 is fixedly connected to the optical axis 10 through a through hole 14. The first shaft 4, the second shaft 6, and the third shaft 12 are all provided with a fixing groove 17. A retaining ring is fixedly installed in the fixing groove 17. The retaining rings fix each shaft to the corresponding connecting seat, thereby achieving reliable positioning of the shaft.

[0042] During the operation of the clamping device, the operator rotates knob 9, causing adjusting screw 8 to rotate. Because adjusting screw 8 engages with the screw hole 7 of the second shaft 6, it moves linearly during rotation. The optical shaft 10 rotates freely within the through hole 14 of the third connecting seat 13. The third connecting seat 13 is movably connected to the connecting ear 11 of the gripper 5 via the third shaft 12, thereby driving the gripper 5 to swing around the first shaft 4, achieving rapid clamping or releasing of the product. Snap rings are installed in the fixing grooves 17 of each shaft, firmly fixing the shaft to the connecting seat, preventing the shaft from disengaging or shifting during movement, and ensuring the stability and accuracy of the clamping action.

[0043] In this embodiment, the use of the retaining ring simplifies the assembly process between the shaft and the connecting seat. No complex tools or additional fasteners are required, allowing operators to quickly complete the installation and reducing assembly difficulty. Simultaneously, the retaining ring structure reduces the number of parts and processing steps, improving production efficiency and lowering overall manufacturing costs. By fixing the shaft with the retaining ring, the device maintains structural stability during long-term use, avoiding problems such as clamping force fluctuations or decreased adjustment accuracy caused by shaft loosening.

[0044] In specific applications of the clamping device, the rotation of knob 9 drives the linear movement of adjusting screw 8. The connection between optical axis 10 and third connecting seat 13 transmits motion to gripper 5. Gripper 5 swings around first shaft 4 to clamp or release the workpiece. The retaining ring ensures that each shaft remains fixedly connected to the connecting seat during movement, avoiding mechanism jamming or wear caused by shaft displacement and extending the device's service life. This design simplifies the fixing method, improves the device's reliability and ease of operation, and is suitable for various industrial clamping scenarios.

[0045] Overall, this embodiment achieves efficient assembly and stable operation of the knob-type quick clamping device by fixing the shaft with a buckle, overcoming the shortcomings of traditional clamping devices such as complex structure and inconvenient adjustment. It also reduces production costs and assembly difficulty, while improving processing efficiency. The device exhibits good clamping force and adjustment accuracy during operation, making it suitable for manual clamping needs and meeting the requirements of industrial production for a simple and economical clamping solution.
