Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and more specifically, it relates to a clamping mechanism for preventing deformation in steel barrel processing. Background Technology

[0002] In existing technologies, while anti-deformation clamping mechanisms for steel drum processing can ensure the stability of the drum body and prevent deformation to a certain extent, these mechanisms still have many shortcomings in practical applications, especially in terms of drum body position adjustment and clamp mold installation and disassembly. First, adjusting the position of the clamped drum body is inconvenient. In actual operation, once the drum body is clamped and fixed, fine-tuning is often cumbersome and difficult to achieve precisely. This inconvenience mainly stems from the clamping mechanism itself lacking sufficient adjustment mechanisms or the adjustment devices being not precise enough. This results in repeated operations for each adjustment, often requiring manual intervention for drum body repositioning. Furthermore, the accuracy of position adjustment is limited, which can easily affect processing quality and may even lead to deformation or damage to the steel drum, thereby reducing production efficiency.

[0003] Furthermore, the existing clamping mold installation and disassembly processes also present significant problems. Mold installation typically involves multiple steps, requiring operators to make adjustments based on different steel drum specifications. This not only demands high operational skills but also carries the risk of insecure installation or damage to the drum due to operational errors. Disassembly of the clamping mold is similarly inconvenient, often cumbersome, requiring tools or complex manual operations. It is time-consuming and labor-intensive, and prone to improper installation or damage. Over time, mold wear becomes more pronounced, gradually reducing its effectiveness and necessitating frequent replacements. This can also cause production line downtime and impact production efficiency. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a clamping mechanism for preventing deformation in steel drum processing, which has the following beneficial effects:

[0017] 1. This utility model is equipped with a position adjustment mechanism. The hydraulic cylinder drives the rotating gear to rotate, and the connecting chain drives the moving frame to slide in the guide groove of the bottom frame. The clamping sleeves installed symmetrically on the moving frame move synchronously, realizing the precise adjustment of the clamping sleeve position to adapt to the clamping requirements of steel drums of different diameters. The hydraulic drive ensures that the clamping sleeves on both sides move synchronously and are evenly stressed, which improves the applicability of the device to steel drums of different specifications, the flexibility of position adjustment, and the balance of clamping force.

[0018] 2. This utility model is equipped with a sleeve installation mechanism. The rotating bottom ring drives the rotating rod to move in the release groove of the longitudinal moving ring. The longitudinal moving ring moves down, causing the inner pressure block to press against the anti-tension spring rod and embed into the inner wall of the snap-fit ​​rod, thereby realizing the quick locking of the clamping sleeve and the moving frame. This mechanism is easy to operate and the locking is reliable. When unlocking, the clamping sleeve can be quickly adjusted or replaced by rotating in the opposite direction. It is convenient to quickly replace clamping sleeves of different sizes according to the specifications of the steel drum, which improves the installation convenience, disassembly efficiency and usage flexibility of the device.

[0019] 3. This utility model is equipped with an installation auxiliary mechanism. The top rotating ring is threadedly connected to the longitudinal moving ring through a threaded plate, driving the longitudinal moving ring to move further so that the inner pressure block can press the anti-tension spring rod more deeply, thereby enhancing the locking force. The bidirectional rotating blocks on the top rotating ring extend into the sides of the adjacent fixing blocks in sequence, and the pressing spring block elastically presses the bidirectional rotating blocks, providing a stepped bidirectional locking and positioning function to prevent the clamping sleeve from loosening or shifting due to clamping force and vibration during the clamping of the steel barrel, thus ensuring the reliability of the clamping sleeve fixation.

[0029] Please see Figures 1-5 A clamping mechanism for preventing deformation during steel drum processing includes a base frame 1, a position adjustment mechanism, a sleeve mounting mechanism, and an installation auxiliary mechanism. The position adjustment mechanism includes a hydraulic cylinder 2 and a moving frame 3. The hydraulic cylinder 2 is fixedly mounted on the base frame 1, and a rotating tooth 4 is rotatably mounted on one end of the hydraulic cylinder 2. The moving frame 3 is slidably mounted on the base frame 1. A connecting chain 5 connects the base frame 1 and the moving frame, and the connecting chain 5 meshes with the rotating tooth 4. Clamping mechanisms are symmetrically mounted on the moving frame 3. Set 6, the set body installation mechanism includes a snap-fit ​​tube 7 and a snap-fit ​​rod 8. A counter-tension spring rod 9 is obliquely and slidably installed on the inner wall of the snap-fit ​​tube 7. A longitudinal sliding ring 10 is longitudinally and slidably installed on the outer wall of the snap-fit ​​tube 7. An inner pressure block 11 is installed on the inner wall of the longitudinal sliding ring 10. The inner pressure block 11 can press against the counter-tension spring rod 9 and embed into the snap-fit ​​rod 8. A top rotating ring 12 is rotatably installed on the outer wall of the snap-fit ​​tube 7. A threaded plate 13 is installed at the bottom end of the top rotating ring 12. The threaded plate 13 is threadedly connected to the longitudinal sliding ring 10.

[0030] In this embodiment, after the hydraulic cylinder 2 is started, it drives the rotating gear 4 to rotate. The rotating gear 4 meshes with the connecting chain 5 for transmission, driving the moving frame 3 to slide directionally along the guide groove 19 on the bottom frame 1. The guide block 20 on the moving frame 3 slides in the guide groove 19 to provide guiding support. The clamping sleeves 6 symmetrically installed on the moving frame 3 move synchronously, realizing precise adjustment of the position of the clamping sleeves 6. Through the extension and retraction control of the hydraulic cylinder 2, the clamping sleeves 6 can move in opposite directions to adapt to the clamping requirements of steel barrels of different diameters, improving the applicability and position adjustment flexibility of the device. One end of the clamping rod 8 is equipped with an end plate 24, which passes through the connecting frame 23 and the mounting frame 2. 2. Insert the clamping tube 7 fixed on the mounting bracket 22. Rotate the bottom rotating ring 14 to drive the rotating rod 16 to move within the release groove 25 of the longitudinal moving ring 10. When the rotating rod 16 moves to the tight end of the release groove 25, the longitudinal moving ring 10 moves down, and the inner pressure block 11 presses against the anti-tension spring rod 9 to embed it into the inner wall of the clamping rod 8, thereby achieving quick locking and fixing of the clamping sleeve 6 and the moving frame 3. This mechanism is easy to operate. When unlocking, rotate the bottom rotating ring 14 in the opposite direction, and the rotating rod 16 moves to the loose end of the release groove 25. The longitudinal moving ring 10 moves up to release the inner pressure block 11, and the anti-tension spring rod 9 pops out to complete the quick unlocking. This facilitates quick adjustment and replacement of the clamping sleeve 6 according to the specifications of the steel drum.

[0031] The installation auxiliary mechanism includes a bottom rotating ring 14 and a bidirectional rotating block 15. The bottom rotating ring 14 is rotatably mounted on the bottom end of the outer wall of the clamping pipe 7. A rotating rod 16 is mounted on the top end of the bottom rotating ring 14. The rotating rod 16 is slidably connected to the longitudinal moving ring 10. A bidirectional rotating block 15 is fixedly mounted on the top end of the top rotating ring 12. A fixing block 17 is fixedly mounted on the outer wall of the clamping pipe 7. A pressure spring block 18 is mounted on the fixing block 17. The bidirectional rotating block 15 can extend into both sides of the adjacent fixing block 17 in both directions.

[0032] In this embodiment, when the top rotating ring 12 is rotated, the threaded connection between the threaded plate 13 and the longitudinal moving ring 10 drives the longitudinal moving ring 10 to move further, so that the inner pressure block 11 presses the anti-tension spring rod 9 more deeply, thereby increasing the locking force. The bidirectional rotating block 15 at the top of the top rotating ring 12 rotates with the top rotating ring 12 and extends into both sides of the adjacent fixing block 17 in sequence. The pressure spring block 18 on the fixing block 17 elastically presses the bidirectional rotating block 15, providing a stepped bidirectional locking positioning. Each time the bidirectional rotating block 15 rotates into a fixing block 17, the pressure spring block 18 presses and fixes it, so that the top rotating ring 12 stays stably in each locking position, preventing the clamping sleeve 6 from loosening due to clamping force and vibration during the clamping of the steel barrel. When unlocking, the top rotating ring 12 is rotated in the opposite direction, the bidirectional rotating block 15 exits the fixing block 17, and the longitudinal moving ring 10 returns to a movable state.

[0033] Please see Figures 1-5As a further implementation of the overall equipment: a guide groove 19 is provided on the bottom frame 1, and guide blocks 20 are installed on both sides of the movable frame 3. The guide blocks 20 and the guide groove 19 are oriented and slidably set. A support block 21 is fixedly installed on the movable frame 3, and an installation frame 22 is installed on the support block 21. The clamping pipe 7 is fixedly installed on the installation frame 22. A connecting frame 23 is installed on the clamping sleeve 6. An end plate 24 is installed on one end of the clamping rod 8, and one end of the clamping rod 8 can pass through the connecting frame 23 and the installation frame 22 to engage with the clamping pipe 7. A release groove 25 is provided on the longitudinal moving ring 10. One end of the rotating rod 16 is slidably connected to the release groove 25. The one end of the rotating rod 16 rotates the one end of the release groove 25, so that the longitudinal moving ring 10 slides and unlocks longitudinally. A bottom plate 26 is installed at the bottom end of the bottom frame 1, and the bottom plate 26 is in contact with the contact surface for support.

[0034] More specifically, before use, according to the diameter of the steel drum, the bottom rotating ring 14 and the top rotating ring 12 are rotated to unlock the sleeve installation mechanism and the installation auxiliary mechanism, and the installation position of the clamping sleeve 6 on the moving frame 3 is adjusted. Then, the bottom rotating ring 14 is rotated again to lock the sleeve installation mechanism, and the top rotating ring 12 is rotated to lock the installation auxiliary mechanism. The bidirectional rotating block 15 extends into the fixing block 17 to provide multi-level stable positioning, ensuring that the clamping sleeve 6 is firmly installed. After the steel drum is placed in place, the hydraulic cylinder 2 is activated to drive the rotating gear 4, which drives the two moving frames 3 on both sides to slide towards each other through the connecting chain 5. The clamping sleeve 6 on the moving frame 3 moves towards the center synchronously and clamps the outer wall of the steel drum. During the clamping process, the double locking of the sleeve installation mechanism and the installation auxiliary mechanism ensures that the clamping sleeve 6 is securely fixed, preventing the clamping sleeve 6 from loosening or shifting position due to clamping force, and avoiding deformation of the steel drum during processing. After processing, the hydraulic cylinder 2 drives in the reverse direction, and the moving frame 3 and the clamping sleeve 6 slide in the opposite direction to release the steel drum. When it is necessary to replace the clamping sleeve 6 with a different specification, the top rotating ring 12 and the bottom rotating ring 14 are rotated in the reverse direction to release the lock, and the clamping sleeve 6 can be quickly disassembled and adjusted or replaced. This improves the position adjustment flexibility, clamping and fixing reliability, anti-deformation effect, disassembly and assembly convenience, and use safety of the steel drum clamping mechanism.

[0035] In summary, during the use or operation of the overall equipment: when the position adjustment mechanism is required, the hydraulic cylinder 2 starts and drives the rotating gear 4 to rotate. The rotating gear 4 meshes with the connecting chain 5, driving the moving frame 3 to slide along the guide groove 19 on the bottom frame 1. The guide block 20 on the moving frame 3 slides in the guide groove 19 to provide guidance and support. The clamping sleeves 6 symmetrically installed on the moving frame 3 move synchronously, realizing precise adjustment of the position of the clamping sleeves 6. Through the extension and retraction control of the hydraulic cylinder 2, the clamping sleeves 6 can move in opposite directions to adapt to the clamping requirements of steel barrels of different diameters, improving the applicability and position adjustment flexibility of the device.

[0036] When the sleeve installation mechanism is in operation, the end plate 24 is installed at one end of the snap-fit ​​rod 8, passes through the connecting frame 23 and the mounting frame 22, and is inserted into the snap-fit ​​tube 7 fixed on the mounting frame 22. The rotating bottom ring 14 drives the rotating rod 16 to move in the release groove 25 of the longitudinal moving ring 10. When the rotating rod 16 moves to the tight end of the release groove 25, the longitudinal moving ring 10 moves down, and the inner pressure block 11 presses against the anti-tension spring rod 9 to embed it into the inner wall of the snap-fit ​​rod 8, thereby realizing the quick locking and fixing of the clamping sleeve 6 and the moving frame 3. The mechanism is easy to operate. When unlocking, the bottom ring 14 is rotated in the opposite direction, the rotating rod 16 moves to the loose end of the release groove 25, the longitudinal moving ring 10 moves up to release the inner pressure block 11, and the anti-tension spring rod 9 pops out to complete the quick unlocking, which is convenient for quick adjustment and replacement of the clamping sleeve 6 according to the steel drum specifications.

[0037] When the auxiliary mechanism needs to be installed, when the top rotating ring 12 is rotated, the threaded connection between the threaded plate 13 and the longitudinal moving ring 10 drives the longitudinal moving ring 10 to move further, so that the inner pressure block 11 presses the anti-tension spring rod 9 more deeply, thereby increasing the locking force. The bidirectional rotating block 15 at the top of the top rotating ring 12 rotates with the top rotating ring 12 and extends into the sides of the adjacent fixed block 17 in sequence. The pressure spring block 18 on the fixed block 17 elastically presses the bidirectional rotating block 15, providing a stepped bidirectional locking positioning. Each time the bidirectional rotating block 15 rotates into a fixed block 17, the pressure spring block 18 presses and fixes it, so that the top rotating ring 12 stays stably in each locking position, preventing the clamping sleeve 6 from loosening due to clamping force and vibration during the clamping of the steel barrel. When unlocking, the top rotating ring 12 is rotated in the opposite direction, the bidirectional rotating block 15 exits the fixed block 17, and the longitudinal moving ring 10 returns to the movable state.

[0038] Before use, according to the diameter of the steel drum, unlock the sleeve installation mechanism and installation auxiliary mechanism by rotating the bottom rotating ring 14 and the top rotating ring 12, adjust the installation position of the clamping sleeve 6 on the moving frame 3, then rotate the bottom rotating ring 14 to lock the sleeve installation mechanism, and then rotate the top rotating ring 12 to lock the installation auxiliary mechanism. The bidirectional rotating block 15 extends into the fixing block 17 to provide multi-level stable positioning, ensuring that the clamping sleeve 6 is firmly installed. After the steel drum is placed in place, start the hydraulic cylinder 2 to drive the rotating gear 4, which drives the two moving frames 3 on both sides to slide towards each other through the connecting chain 5. The clamping sleeve 6 on the moving frame 3 moves towards the center synchronously and clamps the outer wall of the steel drum. During the process, the double locking of the sleeve installation mechanism and the installation auxiliary mechanism ensures that the clamping sleeve 6 is securely fixed, preventing the clamping sleeve 6 from loosening or shifting position due to clamping force, and avoiding deformation of the steel drum during processing. After processing, the hydraulic cylinder 2 drives in the reverse direction, and the moving frame 3 and the clamping sleeve 6 slide in the opposite direction to release the steel drum. When it is necessary to replace the clamping sleeve 6 with a different specification, the top rotating ring 12 and the bottom rotating ring 14 are rotated in the reverse direction to release the lock, and the clamping sleeve 6 can be quickly disassembled and adjusted or replaced. This improves the position adjustment flexibility, clamping and fixing reliability, anti-deformation effect, disassembly and assembly convenience and use safety of the steel drum clamping mechanism.
