Description

Technical Field

[0001] The present invention relates to the technical field of heavy cylinder handling equipment, and specifically to a heavy cylinder handling mechanism. Background Art

[0002] During the workshop production process, it is necessary to handle and transfer some heavy cylinders. Due to their large volume and curved surface, it causes trouble to the staff. Therefore, a special handling mechanism is needed to handle and transfer them.

[0003] There are two conventional handling methods for existing cylinders. One is to clamp the circular surface with a jaw and use a three-jaw mechanism for grasping and handling. The other is to use an air shaft to handle the workpiece. When clamping the outer circular surface, the clamping length is short. When the weight of the heavy cylinder is large and the ratio of length to diameter is relatively large, the fixture mechanism is severely off-loaded, with poor stability, large occupied space, and is not suitable for dense storage. Clamping the inner circular surface occupies less space and is generally used for clamping light cylinders, but it is also prone to off-loading when clamping heavy cylinders, with high requirements for the jaws. The second air shaft is fast and convenient for picking up and placing light cylinders, but it is not convenient for heavy cylinders, generally requires customization, and is expensive. Secondly, the unilateral expansion height of the air shaft is relatively small, about 5 - 6 mm, with a limited tensioning range, and it is not easy to enter the inner side of the cylinder in the case of poor placement position. In addition, the diameter of the conventional air shaft can generally only reach 12 inches, and for cylinders with a larger diameter, non-standard customization is required, with a high price. In addition, the pneumatic tensioning centering function is poor. In view of the above situation, we have developed a heavy cylinder handling mechanism. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a heavy cylinder handling mechanism, which solves the problems mentioned in the above background art that there are two conventional handling methods for existing cylinders. One is to clamp the circular surface with a jaw and use a three-jaw mechanism for grasping and handling. The other is to use an air shaft to handle the workpiece. When clamping the outer circular surface, the clamping length is short. When the weight of the heavy cylinder is large and the ratio of length to diameter is relatively large, the fixture mechanism is severely off-loaded, with poor stability, large occupied space, and is not suitable for dense storage. Clamping the inner circular surface occupies less space and is generally used for clamping light cylinders, but it is also prone to off-loading when clamping heavy cylinders, with high requirements for the jaws. The second air shaft is fast and convenient for picking up and placing light cylinders, but it is not convenient for heavy cylinders, generally requires customization, and is expensive. Secondly, the unilateral expansion height of the air shaft is relatively small, about 5 - 6 mm, with a limited tensioning range, and it is not easy to enter the inner side of the cylinder in the case of poor placement position. In addition, the diameter of the conventional air shaft can generally only reach 12 inches, and for cylinders with a larger diameter, non-standard customization is required, with a high price. In addition, the pneumatic tensioning centering function is poor.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A heavy-duty cylinder handling mechanism includes a bottom plate and a driving assembly. A groove is formed on the surface of the bottom plate, and a guide rod is arranged inside the groove.

A tensioning block is installed outside the inner support block, and rubber particles are arranged on the surface of the tensioning block. A driving block is installed inside the tensioning block, and a telescopic spring is installed inside the driving block. The other end of the telescopic spring is connected to a connecting block, and a guide wheel is connected inside the connecting block. A sliding guide rail is installed inside the inner side of the inner support block, and a guide block is arranged inside the sliding guide rail. A support block is fixed to the other side of the guide block, and an inner support member body is fixed to the other side of the support block. A flange is connected to the top of the inner support member body, and a viewing window is formed on the surface of the inner support member body. The driving assembly is installed inside the inner support member body, and a support seat is connected to the bottom of the driving assembly.

[0006] Optionally, the sliding block forms an elastic structure with the guide rod through the return spring, and the sliding block is movably connected to the guide rod, and the central axis of the sliding block coincides with the central axis of the guide rod.

[0007] Optionally, the bottom plate forms a clamping structure with the inner support block through the stop block and the card slot, and the inner support blocks are distributed in a triangular shape on the surface of the bottom plate, and the stop block and the inner support block are in mutual contact.

[0008] Optionally, the inner support block forms a sliding structure with the bottom plate through the rolling wheel assembly and the driven wheel assembly, and the inner support block is movably connected to the bottom plate, and the rolling wheel assembly and the driven wheel assembly are distributed in a staggered manner.

[0009] Optionally, the tensioning block is fixedly connected to the inner support block, and the tensioning blocks are equidistantly distributed on the outside of the inner support block.

[0010] Optionally, the guide wheel forms a telescopic structure with the driving block through the connecting block and the telescopic spring, and the guide wheel, the connecting block, the telescopic spring and the driving block are on the same axis, and the guide wheel is movably connected to the connecting block.

[0011] Optionally, the guide block forms a fixed structure with the inner support member body through the support block, and the support block and the inner support member body are integrally welded, and the support block is in an inclined structure.

[0012] Optionally, the driving assembly includes a driving member, a piston rod, a floating joint and a locking bolt. The piston rod is connected to the bottom of the driving member, the floating joint is connected to the bottom of the piston rod, and the locking bolt is arranged outside the floating joint.

[0013] Optionally, the floating joint forms a lifting structure between the piston rod and the driving member, and the vertical center line of the floating joint coincides with the vertical center line of the piston rod, and the floating joint is threadedly connected to the locking bolt.

[0014] The present invention provides a heavy-duty cylindrical object transporting mechanism, which has the following beneficial effects:

[0015] 1. The heavy-duty cylindrical object handling mechanism occupies a small space. It mainly realizes the expansion and contraction of the tension block by sliding on the angled inclined plane through the driving member, thereby realizing the handling of the cylindrical object. The mechanism can be designed according to the size and length of the cylindrical object, and has a wide range of adaptability.

[0016] 2. In this heavy-duty cylindrical object handling mechanism, the load generated by handling the cylindrical object is transmitted to the inner support body through the slider, which will not cause damage to the driving mechanism. The tensioning block is in direct contact with the inner circle of the cylindrical object, and the contact surface is an arc surface of the same size as the inner circle of the cylindrical object, which increases the contact area. The tensioning block can be easily replaced after long-term work and wear. Due to the different inclined angles of the mounting slide rails, the tensioning and contraction distances are different. For cylindrical objects with different diameters and different requirements, they can be completed according to the required design needs.

[0017] 3. The heavy-duty cylindrical object transporting mechanism, through the mutual coordination between the bottom plate, the groove, the guide rod, the reset spring and the sliding block, enables the sliding block to slide along the surface of the guide rod, and can be reset by the elastic capacity of the reset spring after sliding, so as to facilitate its operation, and cooperates with the engagement connection between the stop block on one side of the sliding block and the card groove below the inner support block, so that it can ensure that the inner support block can move in the bottom plate while limiting its position, ensuring that the inner support block cannot be separated from the bottom plate when the mechanism is working, thereby ensuring the stability of its operation.

[0018] 4. The heavy-duty cylindrical object handling mechanism, when clamping the cylindrical object, uses a driving member to make the tensioning block slide on an angled slope to achieve its expansion, so that the tensioning block can fit the inner wall of the cylindrical object, and the guide wheel arranged in the middle can change the sliding friction between the tensioning block and the inner wall of the cylindrical object into rolling friction, thereby reducing the wear on the tensioning block. When the cylindrical object covers the mechanism, the guide wheel is squeezed, so that the telescopic spring and the connecting block shrink synchronously, and the guide wheel is stored inside the tensioning block, so that the tensioning block with an arc-shaped surface directly contacts the inner circle of the cylindrical object, thereby increasing the contact area and being replaceable after wear.

[0019] 5. When the driving member moves, the driving force of the heavy cylinder handling mechanism is transmitted to the inner support block and the rolling wheel assembly or the driven wheel assembly through the bottom plate, ensuring that the tensioning block can be tensioned and contracted smoothly, reducing the loss of the driving force caused by friction. Moreover, the overall structure of this mechanism is simple and has a wide adaptability. The tensioning stroke of the tensioning block can be adjusted by adjusting the installation angle of the sliding rail and the driving stroke. In addition, it has a low cost, stable and reliable functions, and can be connected to a robot or other mechanisms through the inner support member body, which is convenient to use.

In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a heavy cylinder handling mechanism, including a bottom plate 1 and a driving assembly 22. A groove 2 is formed on the surface of the bottom plate 1, and a guide rod 3 is arranged inside the groove 2. A sliding block 4 is installed in the middle of the guide rod 3, and a stop block 5 is connected to the surface of the sliding block 4. A return spring 24 is arranged on both sides of the sliding block 4. The sliding block 4 and the guide rod 3 form an elastic structure through the return spring 24, and the sliding block 4 is movably connected to the guide rod 3, and the central axis of the sliding block 4 coincides with the central axis of the guide rod 3. Through the mutual cooperation of the bottom plate 1, the groove 2, the guide rod 3, the return spring 24 and the sliding block 4, the sliding block 4 can slide along the surface of the guide rod 3, and after sliding, it can be reset by the elastic force of the return spring 24, which is convenient for its work;

[0031] An inner support block 6 is installed inside the groove 2, and a card slot 7 is formed below the inner support block 6. The bottom plate 1 and the inner support block 6 form a clamping structure through the stop block 5 and the card slot 7, and the inner support block 6 is distributed in a triangular shape on the surface of the bottom plate 1, and the stop block 5 and the inner support block 6 are mutually attached. Through the clamping connection between the stop block 5 on one side of the sliding block 4 and the card slot 7 below the inner support block 6, it can ensure that while the inner support block 6 moves in the bottom plate 1, it can also be limited, ensuring that the inner support block 6 cannot be separated from the bottom plate 1 when the mechanism works, and ensuring the stability of its work;

[0032] A rolling wheel assembly 8 is installed at the bottom of the inner support block 6, and a driven wheel assembly 9 is arranged above the rolling wheel assembly 8. The inner support block 6 forms a sliding structure with the bottom plate 1 through the rolling wheel assembly 8 and the driven wheel assembly 9, and the inner support block 6 is movably connected to the bottom plate 1. Moreover, the rolling wheel assembly 8 and the driven wheel assembly 9 are arranged in a staggered manner. When the driving member 2201 moves, the driving force is transmitted from the bottom plate 1 to the inner support block 6 and the rolling wheel assembly 8 or the driven wheel assembly 9, ensuring that the tensioning block 10 can be tensioned and contracted smoothly, and reducing the loss of the driving force caused by friction;

[0033] A tensioning block 10 is installed on the outer side of the inner support block 6, and rubber particles 11 are arranged on the surface of the tensioning block 10. A driving block 12 is installed inside the tensioning block 10, and a telescopic spring 13 is installed inside the driving block 12. The other end of the telescopic spring 13 is connected to a connecting block 14, and a guide wheel 15 is connected inside the connecting block 14. The tensioning block 10 is fixedly connected to the inner support block 6, and the tensioning blocks 10 are equidistantly distributed on the outer side of the inner support block 6. The guide wheel 15 forms a telescopic structure with the connecting block 14 and the telescopic spring 13 and the driving block 12, and the guide wheel 15, the connecting block 14, the telescopic spring 13 and the driving block 12 are on the same axis. Moreover, the guide wheel 15 is movably connected to the connecting block 14. When clamping a cylindrical object, through the driving member 2201, the tensioning block 10 slides on an inclined surface with an angle to realize its expansion, so that the tensioning block 10 can fit the inner wall of the cylindrical object. The sliding friction between the tensioning block 10 and the inner wall of the cylindrical object can be changed into rolling friction through the guide wheel 15 arranged in the middle, thereby reducing the wear of the tensioning block 10. When the cylindrical object covers this mechanism, the guide wheel 15 is squeezed, so that the telescopic spring 13 and the connecting block 14 contract synchronously, and the guide wheel 15 is received inside the tensioning block 10, and the tensioning block 10 with an arc-shaped surface directly contacts the inner circle of the cylindrical object, increasing the contact area, and it can be replaced after wear;

[0034] A sliding guide rail 16 is installed on the inner side of the inner support block 6, and a guide block 17 is arranged inside the sliding guide rail 16. The other side of the guide block 17 is fixed with a support block 18, and the other side of the support block 18 is fixed with an inner support member body 19. A flange 20 is connected to the top of the inner support member body 19, and a window 21 is opened on the surface of the inner support member body 19. The driving assembly 22 is installed inside the inner support member body 19, and a support seat 23 is connected to the bottom of the driving assembly 22. The guide block 17 forms a fixed structure with the inner support member body 19 through the support block 18, and the support block 18 and the inner support member body 19 are integrally welded. Moreover, the support block 18 is in an inclined structure. Through the mutual cooperation between the support block 18 and the inner support member body 19, the stability of the device during operation is ensured;

[0035] The driving component 22 includes a driving member 2201, a piston rod 2202, a floating joint 2203 and a locking bolt 2204. The bottom of the driving member 2201 is connected to the piston rod 2202, the bottom of the piston rod 2202 is connected to the floating joint 2203, and the locking bolt 2204 is arranged outside the floating joint 2203. A lifting structure is formed between the floating joint 2203 and the driving member 2201 through the piston rod 2202. The vertical center line of the floating joint 2203 coincides with the vertical center line of the piston rod 2202. Moreover, the floating joint 2203 and the locking bolt 2204 are in threaded connection. By means of the floating joint 2203, the radial force received by the driving member 2201 can be reduced when vertically transporting a cylindrical object, and the structure of the driving member 2201 can be diversified. According to specific situations, it can be pneumatic, hydraulic or electric.

[0036] In summary, when the heavy cylinder handling mechanism is in use, first, the inner support member body 19 can be fixed to a robot or a boosting structure. Then, the driving member 2201 inside the driving assembly 22 is turned on, causing it to push the piston rod 2202 and the floating joint 2203, so that they move along the axial direction of the driving member 2201 relative to the bottom plate 1. The floating joint 2203 can ensure that the radial force on the driving member 2201 is reduced when vertically handling the cylinder, and the structure of the driving member 2201 can be diversified. According to specific situations, it can be pneumatic, hydraulic, or electric. Then, the tensioning block 10 is driven to move radially together with the sliding guide rail 16. When the driving member 2201 retracts, the tensioning block 10 is tensioned to internally support and tighten the cylinder, and the cylinder is clamped by the frictional force between the tensioning block 10 and the inner wall of the cylinder. Finally, when the driving member 2201 extends, the tensioning block 10 contracts accordingly, and the mechanism disengages from the cylinder. Through the mutual cooperation of the bottom plate 1, the groove 2, the guide rod 3, the return spring 24, and the sliding block 4, the sliding block 4 can slide along the surface of the guide rod 3, and after sliding, it can be reset by the elastic force of the return spring 24, facilitating its operation. The engagement connection between the stopper 5 on one side of the sliding block 4 and the card slot 7 below the inner support block 6 ensures that while the inner support block 6 can move in the bottom plate 1, it can also be limited, ensuring that the inner support block 6 does not disengage from the bottom plate 1 during the operation of the mechanism, guaranteeing the stability of its operation. When the driving member 2201 moves, the driving force is transmitted through the bottom plate 1 to the inner support block 6 and the rolling wheel assembly 8 or the driven wheel assembly 9, ensuring that the tensioning block 10 can be tensioned and contracted smoothly, reducing the loss of the driving force due to friction. When clamping the cylinder, the driving member 2201 causes the tensioning block 10 to slide on an angled inclined plane to achieve its expansion, enabling the tensioning block 10 to fit the inner wall of the cylinder. The guide wheel 15 provided in the middle can change the sliding friction between the tensioning block 10 and the inner wall of the cylinder into rolling friction, thereby reducing the wear of the tensioning block 10. When the cylinder covers the mechanism, the guide wheel 15 is squeezed, causing the telescopic spring 13 and the connecting block 14 to contract synchronously, and the guide wheel 15 is retracted into the tensioning block 10, making the tensioning block 10 with an arc-shaped surface directly contact the inner circle of the cylinder, increasing the contact area, and it can be replaced after wear. The load generated by the mechanism when handling the cylinder is transmitted to the inner support member body 19 through the slider, without damaging the driving mechanism. The tensioning block 10 directly contacts the inner circle of the cylinder, and the contact surface is an arc surface with the same size as the inner circle of the cylinder, increasing the contact area, and the tensioning block 10 can be easily replaced after long-term operation and wear. Due to the different inclined plane angles of the installed sliding rails, the tensioning and contraction distances are different. For cylinders with different diameters and requirements, the tensioning stroke of the tensioning block 10 can be designed according to the needs by adjusting the installation angle of the sliding rail and the driving stroke. It has the characteristics of small occupied space, wide adaptation range, low cost, and stable and reliable functions.

[0037] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
