[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention. Example

[0016] like Figure 1-2As shown, the embodiment of the utility model provides a high-rigidity metal clamping tool for machining, including a base 1, a servo motor 3 and a connecting spring 9. The top of the base 1 is fixedly connected to a fixed plate 2, the servo motor 3 is fixedly connected to the front surface of the fixed plate 2, and the driving end of the servo motor 3 is fixedly connected to the driving wheel 4. The top of the base 1 is symmetrically fixedly connected to two fixing rods 5, the two fixing rods 5 are respectively located on both sides of the fixed plate 2, and the top of the fixing rod 5 is fixedly connected to a fixing block 6. The two connecting springs 9 are respectively sleeved on the outer surfaces of the two fixing rods 5, and the top of the connecting spring 9 is fixedly connected to the bottom of the fixed block 6. A movable plate 7 is provided above the base 1, and an electromagnet is provided inside the movable plate 7. The two fixing rods 5 respectively pass through the two ends of the movable plate 7, and the bottom end of the connecting spring 9 is fixedly connected to the top of the movable plate 7. The bottom of the movable plate 7 is adsorbed with a magnetic pressure plate 8, and the two fixing rods 5 respectively pass through the two ends of the magnetic pressure plate 8, and the magnetic pressure plate 8 is located above the base 1.

[0017] The multiple T-shaped slots 10 on the front surface of the magnetic pressure plate 8 are an ingenious design. These not only provide a strong locking force, preventing the limiter module 11 from accidentally falling out during the clamping process, but also allow for a certain degree of fine adjustment within the slots to accommodate workpieces of varying shapes and sizes.

[0018] The diverse bottom surface designs of the limit module 11, such as curved and flat surfaces, further enhance the flexibility of the tooling. This design allows the limit module 11 to closely conform to the complex surface of the workpiece, providing a stable and uniform clamping force, thereby protecting the workpiece from damage and ensuring machining accuracy.

[0019] The drive end of the servo motor 3 is fixedly connected to the eccentric portion of the drive wheel 4. This design enables the drive wheel 4 to generate an eccentric driving force during rotation. This driving force facilitates smoother transitions when adjusting the positions of the movable plate 7 and the magnetic pressure plate 8, reducing vibration and noise caused by sudden impacts. Furthermore, the direct contact between the bottom of the drive wheel 4 and the top of the movable plate 7 ensures efficient and accurate power transmission. This design simplifies the transmission mechanism, reduces failure rates, and improves the overall reliability of the tooling.

[0020] Both the movable plate 7 and the magnetic pressure plate 8 are in contact with the rear surface of the fixed plate 2, a design that helps maintain the stability and rigidity of the fixture structure. During the clamping process, the movable plate 7 and the magnetic pressure plate 8, as the primary clamping components, must withstand significant reaction forces from the workpiece. By closely contacting the fixed plate 2, they are able to more effectively distribute and transmit these forces, thereby ensuring the overall stability and clamping effectiveness of the fixture.

[0021] Working Principle: When using this high-rigidity metal clamping fixture for machining, the operator places the workpiece to be machined onto base 1 and then activates servo motor 3, which drives the drive wheel 4 to rotate. As the drive wheel 4 contacts the movable plate 7, it applies an external force to the movable plate 7 and magnetic pressure plate 8. The high-precision control characteristics of the servo motor 3 ensure that the drive wheel 4 can accurately and stably adjust the position of the movable plate 7 and magnetic pressure plate 8, thereby achieving precise clamping of the workpiece. The electromagnet within the movable plate 7 exerts a repulsive force on the magnetic pressure plate 8. This ingenious design not only enhances the clamping force of the magnetic pressure plate 8 on the workpiece, but also further improves the stability and reliability of the clamping effect by dynamically adjusting the magnitude of the electromagnetic repulsive force. Furthermore, the servo motor 3 drives the drive wheel 4 to adjust the distance between the magnetic pressure plate 8 and base 1, making the fixture flexible and adaptable to workpieces of varying sizes. The fixture's retaining slots 10 and snap-on limiter modules 11 play a crucial role in handling workpieces with complex or irregular shapes. The limiter module 11 fits snugly against the workpiece's limiting surface. Adjusting its position or replacing it with a different-shaped limiter module 11 allows for stable clamping of irregular workpieces. This design not only improves the tooling's adaptability to irregular workpieces but also ensures that the workpiece will not deform or shift due to uneven force during clamping, thus ensuring machining accuracy and workpiece quality.

[0022] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
