Description

Technical Field

[0001] This utility model relates to the field of metal pipe processing technology, specifically to a high-efficiency clamping fixture for metal pipes. Background Technology

[0002] Metal pipes are hollow, long strips of steel, widely used as pipelines for transporting fluids. They are lighter in weight while maintaining the same bending and torsional strength, so they are also widely used in the manufacture of mechanical parts and engineering structures. However, clamping fixtures are required when cutting and processing metal pipes.

[0003] The patent application with publication number CN216801907U, publication date June 24, 2022, entitled "A Clamping Fixture for Cutting Building Pipes," includes a cutting worktable and a movable clamping block. A clamping cylinder is fixedly installed on the cutting worktable, and the cylinder rod of the clamping cylinder is fixedly connected to the movable clamping block. A sliding groove is provided on the cutting worktable, and a positioning end plate is slidably installed in the sliding groove. The clamping device of this utility model uses the clamping cylinder to drive the movable clamping block to clamp and fix the pipe, eliminating the need for manual adjustment of the wrench and simplifying operation. A pressure sensor is installed on one side of the clamping surface of the movable clamping block to control the clamping force and avoid affecting normal cutting due to improper clamping force. The cutting device is equipped with a positioning end plate to limit the end position of the pipe to be cut, thereby accurately controlling the cutting length. The position of the positioning end plate can be automatically adjusted as needed to meet the cutting requirements of different length specifications.

[0004] Existing pipe cutting clamping fixtures use a clamping cylinder to drive a movable clamping block to clamp and fix the pipe. While this can secure the pipe to be cut, it has been found that the movable clamping block cannot stably clamp pipes of different sizes. To achieve stable clamping, the movable clamping block needs to be replaced. Therefore, during the processing of metal pipes, it is necessary to repeatedly change the model of the movable clamping block, resulting in low overall processing efficiency and inconvenience. Therefore, we propose a high-efficiency clamping fixture for metal pipes to solve the problems mentioned above. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency clamping fixture for metal pipes, comprising a base, wherein support legs are symmetrically fixedly connected to the four corners of the bottom of the base, and brackets are symmetrically fixedly connected to the top of both sides of the base, wherein...

[0009] The bracket has an upper clamping plate and a lower clamping plate symmetrically arranged on its inner side.

[0016] 3. Beneficial effects:

[0017] Compared with the prior art, the present invention provides a highly efficient clamping fixture for metal pipes, the specific details of which are as follows:

[0018] (1) When the two ends of the bidirectional hydraulic rod extend and retract, the guide rod can be driven to rise and fall through the transmission rod. The guide rod drives the lower clamping plate to rise and fall. When the lower clamping plate rises and falls, the upper clamping plate can be driven to move in the opposite direction through the transmission mechanism. Thus, through the extension and retraction of a single bidirectional hydraulic rod, multiple upper and lower clamping plates can be quickly controlled to move in the opposite direction at the same time, so that the upper and lower clamping plates can quickly move closer or further away, thereby quickly clamping or releasing the metal pipe. Furthermore, through the V-shaped upper and lower clamping plates, metal pipes of different sizes can be stably clamped, thereby effectively improving the overall processing efficiency of the metal pipe.

[0019] (2) When the bidirectional hydraulic rod drives the lower clamping plate to move up and down, the lower clamping plate drives the second lifting plate to move up and down synchronously through the connecting rod, connecting plate and slider. When the second lifting plate moves, it drives the first toothed rod to move in the opposite direction through the second toothed rod and transmission gear, so that the first toothed rod drives the first lifting plate to move in the opposite direction to the lower clamping plate. The first lifting plate drives the upper clamping plate to move synchronously through the connecting rod, connecting plate and slider, so that the upper clamping plate and the lower clamping plate can move in the opposite direction at the same time, so that the upper clamping plate and the lower clamping plate move closer or further away from each other at the same time, so as to clamp or release the pipe.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0029] Please see Figures 1 to 4 A high-efficiency clamping fixture for metal pipes includes a base 1, with support legs 2 symmetrically fixedly connected to the four corners of the bottom of the base 1, and brackets 3 symmetrically fixedly connected to the top of both sides of the base 1.

[0030] The inner side of the bracket 3 is symmetrically provided with an upper clamping plate 4 and a lower clamping plate 5. When the lower clamping plate 5 moves, the upper clamping plate 4 is driven to move in the opposite direction through the transmission mechanism. A bidirectional hydraulic rod 17 is installed in the middle of the bottom end of the base 1. A guide rod groove 18 passes through the base 1 at the position corresponding to the lower clamping plate 5.

[0031] The bottom of the lower clamping plate 5 is fixedly connected to the guide rod 19 corresponding to the bottom of the guide rod groove 18. The bottom end of the guide rod 19 is rotatably connected to the transmission rod 20. The end of the transmission rod 20 away from the guide rod 19 is rotatably connected to the telescopic end of the bidirectional hydraulic rod 17.

[0032] When the two ends of the bidirectional hydraulic rod 17 extend and retract, the transmission rod 20 can drive the guide rod 19 to rise and fall. The guide rod 19 drives the lower clamping plate 5 to rise and fall. When the lower clamping plate 5 rises and falls, the transmission mechanism can drive the upper clamping plate 4 to move in the opposite direction. Thus, by extending and retracting a single bidirectional hydraulic rod 17, multiple upper clamping plates 4 and lower clamping plates 5 can be quickly controlled to move in opposite directions simultaneously, so that the upper clamping plates 4 and lower clamping plates 5 can quickly move closer or further away. This allows for the rapid clamping or loosening of metal pipes. Furthermore, the V-shaped upper clamping plates 4 and lower clamping plates 5 can stably clamp metal pipes of different sizes, thereby effectively improving the overall processing efficiency of metal pipes.

[0033] Please see Figures 1 to 4 Both the upper clamping plate 4 and the lower clamping plate 5 are V-shaped. The transmission mechanism includes a connecting rod 6. The connecting rod 6 is symmetrically fixedly connected to both sides of the upper clamping plate 4 and the lower clamping plate 5. The end of the connecting rod 6 is fixedly connected to a connecting plate 7. The bracket 3 has symmetrically opened grooves 8 corresponding to the position of the connecting plate 7. The connecting plate 7 is fixedly connected to a slider 9 on one side corresponding to the groove 8. The end of the slider 9 corresponding to the upper clamping plate 4 is fixedly connected to a first lifting plate 10. The end of the slider 9 corresponding to the lower clamping plate 5 is fixedly connected to a second lifting plate 11. The bracket 3 is rotatably connected to the outer side between the first lifting plate 10 and the second lifting plate 11. The bottom of the first lifting plate 10 near the transmission gear 12 is fixedly connected to a first toothed rod 13. The top of the second lifting plate 11 near the other side of the transmission gear 12 is fixedly connected to a second toothed rod 14. A first toothed groove 15 passes through the position corresponding to the first toothed rod 13, and a second toothed groove 16 passes through the position corresponding to the second toothed rod 14. When the bidirectional hydraulic rod 17 drives the lower clamping plate 5 to move up and down, the lower clamping plate 5 drives the second lifting plate 11 to move up and down synchronously through the connecting rod 6, connecting plate 7 and slider 9. When the second lifting plate 11 moves, it drives the first toothed rod 13 to move in the opposite direction through the second toothed rod 14 and transmission gear 12, so that the first toothed rod 13 drives the first lifting plate 10 to move in the opposite direction to the lower clamping plate 5. The first lifting plate 10 drives the upper clamping plate 4 to move synchronously through the connecting rod 6, connecting plate 7 and slider 9, so that the upper clamping plate 4 and the lower clamping plate 5 can move in opposite directions at the same time, so that the upper clamping plate 4 and the lower clamping plate 5 move closer or further away from each other at the same time, so as to clamp or release the pipe.

[0034] Please see Figures 1 to 4The slider 9 is a rectangular column, and the width of the slider 9 matches the inner width of the slide groove 8. The first tooth 13 and the second tooth 14 are located on both sides of the transmission gear 12, and both the first tooth 13 and the second tooth 14 mesh with the transmission gear 12. The guide rod 19 is a rectangular column, and the external dimensions of the guide rod 19 match the internal dimensions of the guide rod groove 18. When the bidirectional hydraulic rod 17 drives the lower clamping plate 5 to rise and fall through the guide rod 19, the rectangular column guide rod 19 and the guide rod groove 18 can guide the rise and fall of the guide rod 19, preventing the guide rod 19 from twisting during rise and fall.

[0035] Working principle: When using this metal tube high-efficiency clamping fixture, such as Figures 1 to 4 As shown, when the two ends of the bidirectional hydraulic rod 17 extend and retract, the transmission rod 20 can drive the guide rod 19 to rise and fall. The guide rod 19 drives the lower clamping plate 5 to rise and fall. When the lower clamping plate 5 rises and falls, the transmission mechanism can drive the upper clamping plate 4 to move in the opposite direction. Thus, through the extension and retraction of a single bidirectional hydraulic rod 17, multiple upper clamping plates 4 and lower clamping plates 5 can be quickly controlled to move in the opposite direction at the same time, so that the upper clamping plates 4 and lower clamping plates 5 can quickly move closer or further away, thereby quickly clamping or releasing the metal pipe. Moreover, through the V-shaped upper clamping plates 4 and lower clamping plates 5, metal pipes of different sizes can be stably clamped, thereby effectively improving the overall processing efficiency of metal pipes.

[0036] When the bidirectional hydraulic rod 17 drives the lower clamping plate 5 to move up and down, the lower clamping plate 5 drives the second lifting plate 11 to move up and down synchronously through the connecting rod 6, connecting plate 7 and slider 9. When the second lifting plate 11 moves, it drives the first toothed rod 13 to move in the opposite direction through the second toothed rod 14 and transmission gear 12, so that the first toothed rod 13 drives the first lifting plate 10 to move in the opposite direction to the lower clamping plate 5. The first lifting plate 10 drives the upper clamping plate 4 to move synchronously through the connecting rod 6, connecting plate 7 and slider 9, so that the upper clamping plate 4 and the lower clamping plate 5 can move in opposite directions at the same time, so that the upper clamping plate 4 and the lower clamping plate 5 move closer or further away from each other at the same time, so as to clamp or release the pipe. When the bidirectional hydraulic rod 17 drives the lower clamping plate 5 to move up and down through the guide rod 19, the guide rod 19 and the guide rod groove 18 can guide the lifting and lowering of the guide rod 19 to avoid the guide rod 19 from twisting during lifting and lowering.
