Description

Technical Field

[0001] This utility model relates to an aluminum electrolytic capacitor aluminum shell clamping device, belonging to the technical field of clamping equipment. Background Technology

[0002] The aluminum casing of an aluminum electrolytic capacitor is a key component of the device, serving multiple functions such as protecting the internal structure, heat dissipation, corrosion resistance, and explosion protection.

[0003] When assembling aluminum electrolytic capacitors and their aluminum shells, clamping devices are usually required to grip and move the aluminum shells. However, commonly used clamping devices rely solely on clamping to hold the aluminum shells. If the friction provided by the clamps is less than the force of gravity, inertia, or external vibration between the aluminum shells and the clamps, the aluminum shells may fall off the clamping devices due to force imbalance, which can easily damage the aluminum shells and affect assembly and use.

[0004] Therefore, there is an urgent need to improve the aluminum shell clamping device for aluminum electrolytic capacitors in order to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum electrolytic capacitor aluminum shell clamping device. By setting the clamping mechanism, when using multiple clamping plates for clamping, a vacuum pump and suction cup are added to vacuum adsorb the aluminum shell. The suction force provided by vacuum adsorption improves the stability of clamping the aluminum shell and prevents the aluminum shell from falling out between the multiple clamping plates, effectively preventing the aluminum shell from being damaged due to falling and affecting its use.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A clamping device for aluminum electrolytic capacitor shells includes a crossbeam. Multiple hydraulic cylinders are fixedly mounted on the bottom of the crossbeam.

The clamping mechanism includes a vacuum pump fixedly mounted on the top of the fixing plate. A suction cup is provided on one end of the vacuum pump extending below the fixing plate. Multiple fixing frames are symmetrically fixedly mounted on the bottom of the fixing plate. A motor is fixedly mounted on one end of each fixing frame. A screw rod, fixedly connected to the output end of the motor, is movably mounted inside each fixing frame. A movable block, threadedly connected to the screw rod, is provided on the screw rod. A support block is fixedly mounted on the bottom of the movable block, and a clamping plate is provided on the bottom of the support block.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown in the figure, this embodiment provides an embodiment of an aluminum electrolytic capacitor aluminum shell clamping device.

[0026] An aluminum electrolytic capacitor aluminum shell clamping device includes a crossbeam 1. Multiple hydraulic cylinders 2 are fixedly mounted on the bottom of the crossbeam 1. A fixing plate 3 is fixedly mounted on the output end of each hydraulic cylinder 2. A clamping mechanism 4 is provided on the fixing plate 3. The clamping mechanism 4 includes a vacuum pump 5 fixedly mounted on the top of the fixing plate 3. A suction cup 6 is provided on one end of the vacuum pump 5 extending below the fixing plate 3. Multiple fixing frames 7 are symmetrically fixedly mounted on the bottom of the fixing plate 3. A motor 8 is fixedly mounted on one end of each fixing frame 7. A screw 9, fixedly connected to the output end of the motor 8, is movably mounted inside each fixing frame 7. A movable block 10, threadedly connected to the screw 9, is provided on the screw 9. A support block 11 is fixedly mounted on the bottom of the movable block 10. A clamping plate 12 is provided on the bottom of the support block 11.

[0027] The clamping mechanism 4 is used to clamp the aluminum shell using a combination of clamping and vacuum adsorption. First, the vacuum pump 5 and suction cup 6 adsorb the aluminum shell from the top. After the aluminum shell is fixed by adsorption, the clamping plates 12 are driven by multiple motors 8 to clamp the aluminum shell from all sides. The suction force provided by vacuum adsorption and the double support of clamping by multiple clamping plates 12 improve the stability of clamping the aluminum shell and prevent the aluminum shell from falling out from between the multiple clamping plates 12. This effectively prevents the aluminum shell from being damaged due to falling and affecting its use.

[0028] In this embodiment, as Figures 1-6 As shown, the support block 11 has an internal mounting groove 13. The top of the clamping plate 12 is fixedly mounted with a mounting block 14 that matches the mounting groove 13. A locking rod 15 that engages with the mounting block 14 is movably mounted on one side of the support block 11. Multiple springs 16 are fixedly mounted between the locking rod 15 and the support block 11. Slide rails 17 are fixedly mounted on both sides of the support block 11. A slide rod 18 is movably mounted on the slide rail 17. A limit block 19 is fixedly mounted on one end of the slide rod 18. Limit grooves 20 are opened on both sides of the locking rod 15. A support plate 21 is fixedly mounted on the surface of the support block 11. Two telescopic rods 22 are symmetrically fixedly mounted on one end of the support plate 21. A positioning block 23 is fixedly mounted on one end of the telescopic rod 22. Two positioning grooves 24 are symmetrically opened on one end of the locking rod 15.

[0029] Through the arrangement of mounting slot 13, mounting block 14, locking rod 15, and spring 16, the support block 11 and clamping plate 12 are fixed together by the connection and engagement of mounting block 14 and locking rod 15. Since the locking rod 15 is supported by multiple springs 16, it can be pulled to detach from mounting block 14, thus facilitating the disassembly and replacement of clamping plate 12. This allows for adaptation to different aluminum shell shapes, such as round or square, enabling better clamping of aluminum shells of various shapes. The arrangement of slide rail 17, slide rod 18, limiting block 19, and limiting groove 20 provides secondary tightening of the locking rod 15. After mounting block 14 engages with locking rod 15, sliding rod 18 slides on slide rail 17, causing limiting block 19 to insert into limiting groove 20. The engagement of limiting block 19 and limiting groove 20 provides secondary fixation of locking rod 15, preventing it from loosening and detaching from mounting block 14. The clamping plate 12 may fall off. Through the arrangement of the support plate 21, telescopic rod 22, positioning block 23, and positioning groove 24, when replacing the clamping plate 12, after separating the locking rod 15 from the mounting block 14 and disassembling the clamping plate 12, the locking rod 15 will reset under the influence of the spring 16. To avoid having to pull the locking rod 15 again when installing the clamping plate 12, when pulling the locking rod 15 to disassemble, one end of the locking rod 15 is pulled to below one end of the support plate 21, and then the positioning block 23 is pushed into the positioning groove 24 on the locking rod 15. With the connection between the positioning block 23 and the positioning groove 24, and the support of the support plate 21 and telescopic rod 22, the locking rod 15 can be limited, effectively preventing the locking rod 15 from resetting and avoiding repeated pulling of the locking rod 15 during installation. After separating the positioning block 23 from the positioning groove 24, the locking rod 15 can reset under the elastic force of the spring 16 and engage with the mounting block 14.

[0030] In this embodiment, as Figures 1-6 As shown, multiple fixing blocks 25 are symmetrically fixedly installed on the surface of one end of the vacuum pump 5 and the surface of one end of the suction cup 6. Bolts 26 are installed between the opposing fixing blocks 25. A sealing groove 27 is opened on the bottom of one end of the vacuum pump 5. A sealing ring 28 is fixedly installed on the top of the suction cup 6. Multiple anti-slip blocks 29 are evenly fixedly installed on the surface of the bolts 26. An anti-slip plate 30 is fixedly installed on one side of the clamping plate 12.

[0031] With the fixing blocks 25 and bolts 26, the vacuum pump 5 and the suction cup 6 are fixed together by the connection of multiple fixing blocks 25 and bolts 26. This allows the suction cup 6 to be detached from one end of the vacuum pump 5, making it easy to replace it in time if the suction cup 6 is damaged. With the sealing groove 27 and sealing ring 28, after the vacuum pump 5 and the suction cup 6 are connected, the sealing ring 28 on the top of the suction cup 6 is inserted into the sealing groove 27 opened in the vacuum pump 5, thereby increasing the sealing at the connection between the vacuum pump 5 and the suction cup 6 and preventing gas from entering and affecting the suction. With the anti-slip blocks 29 and anti-slip plates 30, the multiple anti-slip blocks 29 increase the friction on one end of the bolt 26, while the anti-slip plates 30 increase the friction on one side of the clamping plate 12.

[0032] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the aluminum electrolytic capacitor aluminum shell clamping device provided in this embodiment is as follows:

[0033] After connecting the hydraulic cylinder 2 to an external hydraulic power system, multiple hydraulic cylinders 2 drive the fixed plate 3 to descend and approach the aluminum shell. Then, the vacuum pump 5 is connected to an external power source and started, relying on the suction cup 6 to vacuum adsorb the aluminum shell. After adsorption is completed, multiple motors 8 are started simultaneously to drive the screw 9 to rotate and transmit, so that the movable block 10 on the screw 9 drives the support block 11 and the clamping plate 12 to move. Finally, multiple clamping plates 12 clamp the aluminum shell from all sides. After adsorption and clamping are completed, the hydraulic cylinder 2 can be started to drive the fixed plate 3 to rise to transport the aluminum shell.

However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
