Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal spraying, in particular to a thermal spraying rotary clamping mechanism. Background Art
[0002] Thermal spraying is a surface coating technique that involves spraying molten or semi-molten material onto a substrate to form a coating that improves the substrate's performance and durability. This technique is commonly used to enhance a material's hardness, corrosion resistance, wear resistance, thermal conductivity, or other specific properties. Thermal spraying can be applied to a variety of materials, such as metals, ceramics, and alloys, and is widely used in aerospace, automotive, electronics, energy, and other fields. A thermal spray clamping mechanism is a device or apparatus used to support and secure a workpiece (typically a component to be thermally sprayed). During the thermal spraying process, the workpiece needs to be stably positioned on the workbench of the spraying equipment to ensure uniformity and quality of the coating. The clamping mechanism is typically designed to secure the workpiece in the correct position and angle while being able to withstand the heat and mechanical forces generated during the thermal spraying process. Existing thermal spray clamping mechanisms rely on simple mechanical fixation or single-angle clamping, which can lead to workpiece movement or instability during operation, affecting processing accuracy and quality. Frequent workpiece position adjustment or re-clamping is also required, especially when multi-surface spraying or processing is required, increasing operation time and complexity. Utility Model Content
[0003] The utility model provides a thermal spraying rotary clamping mechanism, which solves the above-mentioned technical problems.
[0004] The utility model solves the above-mentioned technical problems as follows:
[0005] A thermal spraying rotary clamping mechanism includes a movable clamping block, a fixed clamping block, a gear ring and a base, wherein the fixed clamping block is fixed on the base, the fixed clamping block is provided with a guide rod, a movable clamping block is installed on one side of the fixed clamping block on the base through the guide rod guidance, the movable clamping block is provided with a first slot and a second slot, and a main shaft is provided at the bottom end of the base, and the main shaft is installed on a bearing seat.
[0006] On the basis of the above technical solution, the present invention can also be improved as follows.
[0007] Furthermore, the inner sides of the movable clamping block and the fixed clamping block are both provided with accommodating grooves.
[0008] The beneficial effects of adopting the above further scheme are:
[0009] The receiving slot provides a fixed position for the strong magnet and electromagnet, allowing them to be precisely aligned during the clamping process, thus ensuring the stability and reliability of magnetic adsorption. This design effectively prevents the clamp from shifting due to vibration or external forces during the spraying process, ensuring that the workpiece remains stable throughout the operation. The strong magnet and electromagnet installed in the receiving slot enable rapid clamping and release operations through magnetic force. Compared to traditional mechanical clamping methods, magnetic clamping can significantly shorten operation time and improve work efficiency, making it particularly suitable for production environments that require frequent workpiece changes.
[0010] Furthermore, a strong magnet is installed in the receiving groove of the movable clamp.
[0011] The beneficial effects of adopting the above further scheme are:
[0012] Strong magnets provide a powerful magnetic attraction, interacting with the electromagnets on the fixed clamps to securely clamp the workpiece. Compared to mechanical clamping, magnetic clamping is more uniform and reliable, preventing workpiece displacement or loosening during the spraying process. Because the clamping force is provided by magnets, direct contact and friction between mechanical components are reduced, reducing wear and maintenance costs. The strong magnets' non-contact clamping extends the life of the clamping mechanism.
[0013] Furthermore, an electromagnet is installed in the receiving groove of the fixed clamping block.
[0014] The beneficial effects of adopting the above further scheme are:
[0015] Electromagnets can control the strength and opening and closing of their magnetic force through electric current, making the clamping and release of workpieces more flexible and controllable. Operators can quickly open and close the electromagnet as needed, quickly clamping or releasing the workpiece and improving work efficiency. The electromagnet generates a strong magnetic field that interacts with the strong magnets in the movable clamping block to provide a strong clamping force. Compared to mechanical clamping methods, electromagnets can hold the workpiece more evenly and securely, ensuring that the workpiece does not loosen or shift during high-intensity operations.
[0016] Furthermore, the positions and sizes of the strong magnet and the electromagnet are matched.
[0017] The beneficial effects of adopting the above further scheme are:
[0018] By precisely matching the position and size of the strong magnets and electromagnets, we ensure maximum magnetic force between them. This design provides sufficient clamping force to secure the workpiece securely, preventing slippage or loosening during operation. The precise matching of the position and size of the strong magnets and electromagnets ensures even distribution of magnetic force on the workpiece, enhancing clamping stability. This helps maintain the workpiece's precise position during the spraying process, improving spray quality and consistency.
[0019] Furthermore, a stopper is provided at one end of the guide rod away from the fixed clamping block, and the movable clamping block is mounted on the guide rod by being limited by the stopper.
[0020] The beneficial effects of adopting the above further scheme are:
[0021] The stopper effectively prevents the movable clamp from sliding off the guide rod during use, ensuring that the movable clamp always remains in the correct position on the guide rod. The stopper provides a stable limit function, ensuring that the movable clamp's range of movement on the guide rod is fixed. This helps maintain precise positioning when installing the workpiece, improving the accuracy and consistency of the clamping and spraying processes.
[0022] Furthermore, the second slot is arc-shaped.
[0023] The beneficial effects of adopting the above further scheme are:
[0024] The curved clamping groove can accommodate workpieces of various shapes and sizes, especially those with round or curved surfaces. Compared to straight clamping grooves, the curved design conforms better to the workpiece surface, providing a more stable clamp. Furthermore, the curved clamping groove design provides a uniform contact area, distributing the clamping force and reducing localized stress concentrations. This helps increase clamping force while avoiding damage to the workpiece surface.
[0025] Furthermore, the base is rotatably mounted on the fixed platform via a bearing seat.
[0026] The beneficial effects of adopting the above further scheme are:
[0027] The bearing housing design allows the base to rotate freely, facilitating thermal spraying or other machining operations. This flexibility helps cover all workpiece surfaces, ensuring uniformity and integrity of the coating or machining process. The rotation capability allows for machining at multiple angles while the workpiece is fixed, reducing errors caused by repeated re-clamping and improving machining accuracy and consistency. Furthermore, the rotation function allows the spray unit to evenly coat the workpiece surface, avoiding blind spots and uneven coating, thereby improving coating quality and surface finish.
[0028] The beneficial effects of the utility model are:
[0029] The clamping mechanism utilizes a combination of movable and fixed blocks. The fixed block is mounted on the base, while the movable block slides on the base via a guide rod and is limited by a stop. This design ensures the stability and reliability of the clamping mechanism during operation. The stop effectively limits the range of motion of the movable block.
[0030] Both the movable and fixed clamps feature receiving slots, each housing a strong magnet and an electromagnet. The coordinated positioning and size of the magnets and electromagnets allow the movable clamp to be quickly secured to the fixed clamp via magnetic attraction. This magnetic attraction method is not only easy to operate but also provides stable clamping force, ensuring that the workpiece does not move or shake during the spraying process, thereby ensuring accurate and consistent spraying.
[0031] The movable clamping block is designed with a first and second slot, the second slot being arc-shaped. This design allows the clamping mechanism to accommodate workpieces of varying shapes and sizes. The first slot is used to secure smaller or regularly shaped workpieces, while the arc-shaped second slot is suitable for irregularly shaped workpieces, enhancing the flexibility and versatility of the clamping mechanism.
[0032] The base is mounted with a spindle secured by a bearing block, allowing the entire base to rotate on a fixed platform. This rotational feature allows the operator to rotate the clamping mechanism and workpiece as needed to achieve optimal coating results during the thermal spray process. This rotation helps evenly distribute the spray material, improving the quality and uniformity of the coating.

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.
[0042] See also Figures 1 to 3 As shown, the embodiment provided by the utility model:
[0043] Example 1
[0044] A thermal spraying rotary clamping mechanism includes a movable clamping block 1, a fixed clamping block 4, a gear ring 5, and a base 6. The fixed clamping block 4 is fixed to the base 6, and the fixed clamping block 4 is provided with a guide rod 7. The movable clamping block 1 is installed on the side of the base 6 on which the fixed clamping block 4 is guided by the guide rod 7. The guide rod 7 is provided with a stopper 8 at the end facing away from the fixed clamping block 4. The movable clamping block 1 is limited and installed on the guide rod 7 by the stopper 8. The setting of the stopper 8 can effectively prevent the movable clamping block 1 from sliding off the guide rod 7 during use, ensuring that the movable clamping block 1 always remains in the correct position on the guide rod 7. The stopper 8 can provide a stable limiting function, ensuring that the range of movement of the movable clamping block 1 on the guide rod 7 is fixed. This helps to maintain precise positioning when installing the workpiece and improves the accuracy and consistency of the clamping and spraying processes. The inner sides of the movable clamping block 1 and the fixed clamping block 4 are both provided with a receiving groove 13. The receiving groove 13 provides a fixed position for the strong magnet 10 and the electromagnet 12, so that they can be accurately aligned during the clamping process, thereby ensuring the stability and reliability of the magnetic adsorption. This design can effectively prevent the clamp from shifting due to vibration or external force during the spraying process, ensuring that the workpiece remains stable during the entire operation. A strong magnet 10 and an electromagnet 12 are installed in the receiving groove 13, and rapid clamping and releasing operations can be achieved through magnetic force. Compared with traditional mechanical clamping methods, magnetic clamping can significantly shorten the operation time and improve work efficiency. It is particularly suitable for production environments that require frequent replacement of workpieces. A strong magnet 10 is installed in the receiving groove 13 of the movable clamp 1. The strong magnet 10 can provide a strong magnetic attraction and interact with the electromagnet 12 on the fixed clamp 4 to firmly clamp the workpiece. Compared with the mechanical clamping method, magnetic clamping is more uniform and reliable, avoiding displacement or loosening of the workpiece during the spraying process. Since the clamping force is provided by the magnet, direct contact and friction between mechanical components are reduced, reducing wear and maintenance costs. The non-contact clamping method of the strong magnet 10 extends the service life of the clamping mechanism. An electromagnet 12 is installed in the receiving groove 13 of the fixed clamping block 4. The electromagnet 12 can control the strength and opening and closing of its magnetic force through electric current, which makes the process of clamping and releasing the workpiece more flexible and controllable. The operator can quickly open or close the electromagnet 12 as needed to quickly clamp or release the workpiece, improving work efficiency. The electromagnet 12 can generate a strong magnetic field, which interacts with the strong magnet 10 on the movable clamping block 1 to provide a strong clamping force. Compared with the mechanical clamping method, the electromagnet 12 can fix the workpiece more evenly and firmly, ensuring that the workpiece will not loosen or shift during high-intensity operation. The position and size of the strong magnet 10 and the electromagnet 12 are adapted to each other. By precisely matching the position and size of the strong magnet 10 and the electromagnet 12, it is ensured that the maximum magnetic effect can be generated between them. This design can provide sufficient clamping force to stably fix the workpiece and avoid slipping or loosening during operation. The positions and sizes of the strong magnet 10 and the electromagnet 12 are precisely matched to ensure that the magnetic force is evenly distributed on the workpiece, thereby improving the stability of the clamping.This helps maintain the precise position of the workpiece during the spraying process, improving spraying quality and consistency. The movable clamping block 1 is provided with a first slot 2 and a second slot 3. The second slot 3 is arc-shaped, which can accommodate workpieces of various shapes and sizes, particularly round or curved workpieces. Compared to linear slots, the arc-shaped design better conforms to the workpiece surface and provides a more stable clamp. Furthermore, the arc-shaped slot design provides a uniform contact area, thereby distributing the clamping force and reducing localized stress concentration. This helps increase clamping force while avoiding damage to the workpiece surface. A spindle 11 is provided at the bottom end of the base 6 and is mounted on a bearing seat 9. The base 6 is rotatably mounted on a fixed platform via the bearing seat 9. The design of the bearing seat 9 allows the base 6 to rotate freely, facilitating thermal spraying or other machining operations. This flexibility helps cover all surfaces of the workpiece, ensuring uniformity and integrity of the spraying or machining process. The rotation function enables the workpiece to be machined at multiple angles while in a fixed clamped state, reducing errors caused by repeated re-clamping and improving machining accuracy and consistency. The rotation function enables the spray device to evenly cover the surface of the workpiece, avoiding dead angles and uneven spraying, thereby improving the spraying quality and surface finish.
[0045] A thermal spraying rotary clamping mechanism based on Example 1 is used as follows:
[0046] The design combines a movable clamping block 1 with a fixed clamping block 4. The fixed clamping block 4 is mounted on a base 6. The movable clamping block 1 slides on the base 6 via a guide rod 7 and is limited by a stopper 8. This design ensures the stability and reliability of the clamping mechanism during operation. The provision of the stopper 8 effectively limits the range of movement of the movable clamping block 1.
[0047] Both the movable clamping block 1 and the fixed clamping block 4 are provided with a receiving groove 13, each housing a strong magnet 10 and an electromagnet 12. The coordinated positioning and size of the strong magnet 10 and the electromagnet 12 allow the movable clamping block 1 to be quickly secured to the fixed clamping block 4 through magnetic attraction. This magnetic attraction method is not only simple to operate but also provides a stable clamping force, ensuring that the workpiece does not move or shake during the spraying process, thereby ensuring accurate and consistent spraying.
[0048] The movable clamping block 1 is designed with a first slot 2 and a second slot 3, with the second slot 3 being arc-shaped. This design allows the clamping mechanism to accommodate workpieces of varying shapes and sizes. The first slot 2 is used to secure smaller or regularly shaped workpieces, while the arc-shaped second slot 3 is suitable for irregularly shaped workpieces, enhancing the flexibility and versatility of the clamping mechanism.
[0049] A spindle 11 is mounted on the base 6 and secured by a bearing block 9, allowing the entire base 6 to rotate on a fixed platform. This rotational feature allows the operator to rotate the clamping mechanism and workpiece as needed to achieve a better coating effect during the thermal spraying process. This rotation helps evenly distribute the spray material, improving the quality and uniformity of the coating.
[0050] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
