[0042] The present invention provides a jaw mechanism.

[0043] Please refer to Figures 1 to 3 , in an embodiment of the present invention, the jaw mechanism includes a connecting plate 10, a lower jaw 20, a lever plate 30, and an upper jaw 40; the lower jaw 20 is provided on the connecting plate 10; the middle position of the lever plate 30 is hinged to the connecting plate 10; the upper jaw 40 is connected to one end of the lever plate 30 adjacent to the lower jaw 20 and is disposed opposite to the lower jaw 20; when one end of the lever plate 30 away from the upper jaw 40 contacts the lifting device 2, it drives the upper jaw 40 away from the lower jaw 20, so that the upper jaw 40 and the lower jaw 20 are in an open state.

[0044] When the end of the lever plate 30 away from the upper jaw 40 contacts the lifting device 2, the upward movement of the lifting device 2 causes the lever plate 30 to rotate around the hinge point. As the lever plate 30 rotates, the upper jaw 40 moves away from the lower jaw 20, causing the upper jaw 40 and the lower jaw 20 to be in an open state. When it is necessary to clamp the magnetic core, by controlling the downward movement of the lifting device 2, the lever plate 30 returns to its original position, and the upper jaw 40 and the lower jaw 20 close, thereby clamping the magnetic core.

[0045] The jaw mechanism of the present utility model adopts the lever principle. Through the hinge action of the lever plate 30, the synchronous movement of the upper jaw 40 and the lower jaw 20 is realized. When the end of the lever plate 30 away from the upper jaw 40 contacts the lifting device 2, it can drive the upper jaw 40 to move away from the lower jaw 20, causing the upper jaw 40 and the lower jaw 20 to be in an open state. This design greatly reduces the complexity of the mechanism, simplifies the operation process, and improves the reliability of the equipment.

[0046] Through the reasonable layout of the connecting plate 10, the lower jaw 20, the lever plate 30 and the upper jaw 40, the entire mechanism realizes the maximum operating range while occupying the smallest space, thereby improving the flexibility of the transfer device of the winding equipment.

[0047] In one embodiment, please refer to Figures 1 to 3 , an installation hole 30a is provided at the end of the lever plate 30 away from the upper jaw 40; the jaw mechanism further includes an installation shaft 50 and a support spring 60. The installation shaft 50 is provided on the connecting plate 10 and movably passes through the installation hole 30a. The support spring 60 is sleeved on the installation shaft 50, and both ends of the support spring 60 are respectively connected to the lever plate 30 and the connecting plate 10.

[0048] By providing the installation hole 30a at the end of the lever plate 30 away from the upper jaw 40, the design of the jaw mechanism is optimized, and the overall stability and reliability of the clamping device are improved. This structural design makes the connection between the lever plate 30 and the upper jaw 40 more firm, effectively avoiding structural loosening caused by vibration or external force during operation, thereby ensuring the stability and repeat accuracy of the clamping work.

[0049] The components of the jaw mechanism further include a mounting shaft 50 and a support spring 60. The mounting shaft 50 is provided on the connecting plate 10 and movably passes through the mounting hole 30a. This design provides the jaw mechanism with freedom of movement in the horizontal direction, increasing the adaptability of the clamping device to workpieces of different sizes and shapes. The support spring 60 is sleeved in the mounting shaft 50, and both ends of the support spring 60 are respectively connected to the lever plate 30 and the connecting plate 10. This design enables the jaw mechanism to provide appropriate elastic force when clamping workpieces, ensuring stable clamping of the workpieces during the processing, and at the same time reducing the damage to the workpieces caused by excessive clamping force. The application of the support spring 60 also improves the fatigue life of the jaw mechanism and reduces the failure rate caused by spring fatigue failure.

[0050] In one embodiment, please refer to Figures 1 to 3 , the mounting hole 30a is an oval hole.

[0051] Due to the shape characteristics of the oval hole, during the installation process, the components can be allowed to adjust their positions within a certain range, so as to adapt to different installation environments and requirements. The structural design of the oval hole can better adapt to the shape changes of the connecting components, making the connection more compact and improving the stability of the overall structure. Compared with traditional circular holes or square holes, when the oval hole is subjected to external forces, it can more effectively disperse stress and reduce the risk of structural damage caused by stress concentration.

[0052] In one embodiment, please refer to Figures 1 to 3 , a limiting portion is provided at one end of the mounting shaft 50 away from the connecting plate 10, and the limiting portion is used to abut against the lever plate 30.

[0053] In terms of structural stability, the setting of the limiting portion can effectively limit the movement range of the lever plate 30, thereby enhancing the stability and reliability of the entire device. Due to the abutment of the limiting portion against the lever plate 30, the lever plate 30 will not exceed the preset range during the movement process, avoiding structural failure or damage caused by excessive movement of the lever plate 30, greatly improving the service life of the device, and thus reducing the risk of safety accidents.

[0054] In one embodiment, please refer to Figures 1 to 3 , the lever plate 30 includes a clamping section 31, a connecting section 32 and a contact section 33. One end of the clamping section 31 is hinged to the connecting plate 10, and the other end of the clamping section 31 is connected to the upper jaw 40; the connecting section 32 is connected to one end of the clamping section 31 hinged to the connecting plate 10; the connecting section 32 and the clamping section 31 are arranged at an angle; the contact section 33 is connected to the end of the connecting section 32 away from the clamping section 31; the contact section 33 is used to contact the lifting device 2; the contact section 33 and the connecting section 32 are arranged at an angle.

[0055] The connecting section 32 and the clamping section 31 are hinged to one end of the connecting plate 10 and are arranged at an angle. This design optimizes the force transmission path, making the clamping section 31 higher than the contact section 33. In this way, when the contact section 33 only needs to rotate a small angle, it can drive the clamping section 31 and the lower jaw 20 to clamp the magnetic core, making the whole structure more stable during operation. The contact section 33 is connected to one end of the connecting section 32 far from the clamping section 31 and is used to contact the lifting device 2. This design enables the lever plate 30 to cooperate efficiently with the lifting device 2, improving the work efficiency.

[0056] In one embodiment, please refer to Figures 1 to 3 , a contact portion is provided at one end of the contact section 33 far from the connecting section 32, and the contact portion is a wear-resistant material component.

[0057] The contact portion is made of wear-resistant material, effectively improving the wear resistance of the component during contact, reducing failures and maintenance costs caused by wear. During long-term use, the wear degree of the contact portion is significantly lower than that of traditional materials, thus extending the service life of the equipment. The design of the contact portion improves the contact stability. This structural design makes the operation of the whole system more reliable and reduces the risk of failures caused by poor contact.

[0058] In one embodiment, please refer to Figures 1 to 3 , the jaw mechanism further includes a jaw mounting seat 70 provided on the connecting plate 10. The jaw mounting seat 70 is located at one end of the connecting plate 10 far from the lifting device 2; one end of the lever plate 30 is hinged to the jaw mounting seat 70.

[0059] By providing the jaw mounting seat 70 on the connecting plate 10, the position of the jaw can be flexibly adjusted, greatly improving the adaptability of the clamping work. The jaw mounting seat 70 is located at one end of the connecting plate 10 far from the lifting device 2. Such a design can effectively avoid interference generated during the operation of the lifting device 2, ensuring the stability and reliability of the jaw work. One end of the lever plate 30 is hinged to the jaw mounting seat 70. This structural design makes the movement of the jaw more flexible, and it can achieve efficient clamping and handling operations in different working environments. Due to the application of the lever principle, the clamping force and precision of the jaw have been significantly improved, thus greatly improving the precision and efficiency of workpiece processing.

[0060] In one embodiment, the jaw mounting seat 70 includes a jaw mounting plate and a fixing block. The jaw mounting plate is fixed to the connecting plate 10; the fixing block is connected to the jaw mounting plate, and the lower jaw 20 is detachably connected to the fixing block; and the fixing block and the jaw mounting plate are an integrally formed structure.

[0061] The jaw mounting base 70 adopts an integrally formed structure of a jaw mounting plate and a fixing block, which overcomes the disadvantages of numerous components and complex structure in the prior art. The design of the integrally formed structure not only simplifies the manufacturing process but also reduces the production cost. Since the jaw mounting plate is fixed to the connecting plate 10, the fixing block is connected to the jaw mounting plate, and the lower jaw 20 is detachably connected to the fixing block, this design makes the jaw mounting base 70 have extremely high stability and reliability.

[0062] In one embodiment, please refer to Figures 1 to 3 , the jaw mechanism further includes at least two reinforcing ribs, and the two reinforcing ribs are connected to the jaw mounting plate and the fixing block and are located on both sides of the fixing block.

[0063] Due to the connection of the reinforcing ribs to the jaw mounting plate and the fixing block, a more robust support system is formed, so that when the jaw mechanism performs the grasping task, it can withstand a greater load, avoiding structural deformation or damage caused by excessive load, and greatly improving the service life of the jaw mechanism. The layout design of the two-sided reinforcing ribs optimizes the force distribution of the jaw mechanism, enabling the jaws to distribute force more evenly when grasping an object, effectively solving the problem of unstable clamping caused by uneven force in the prior art, and improving the clamping accuracy and operation efficiency.

[0064] The present utility model also proposes a winding device, please refer to Figures 1 to 3 , the winding device includes a base, an indexing plate 1, a lifting device 2, a winding device and the jaw mechanism; the indexing plate 1 is arranged on the base; the lifting device 2 is installed on the indexing plate 1; the winding device is arranged on the base and is adjacent to the indexing plate 1; the jaw mechanism is connected to the indexing plate 1; when the lifting device 2 contacts the lever plate 30 of the jaw mechanism, the jaw mechanism is in an open state. The specific structure of the jaw mechanism refers to the above embodiment. Since this winding device adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.

[0065] The design of the lifting device 2 contacting the lever plate 30 of the jaw mechanism makes the jaw mechanism more stable in the open state. This structural design effectively avoids equipment failures caused by vibration or external interference, and improves the stability and reliability of the equipment. The effective cooperation between the lifting device 2 and the jaw mechanism ensures the coherence and stability of the winding operation, making the production process more efficient. Compared with the prior art, the present utility model can complete more winding tasks in the same time, effectively reducing the production cost.

[0066] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly.
