Description

Technical Field

[0001] This invention relates to the field of fire hydrant processing technology, and more particularly to a workpiece processing device for fire hydrant production. Background Technology

[0002] As a crucial component of urban fire protection systems, the quality of the processing of fire hydrants' pipe components directly impacts their sealing performance and service life. Pipe cutting is a critical processing step in fire hydrant production, requiring precise cutting of metal pipes to ensure end-face flatness and dimensional accuracy. Traditional pipe cutting typically relies on manual operation or simple mechanical equipment, resulting in low processing efficiency, poor positioning accuracy, and inconsistent cut quality, making it difficult to meet the demands of modern mass production of fire hydrants.

[0003] In the existing technology, processing devices for pipe cutting mainly include fixed cutting equipment and semi-automatic cutting machine tools. Fixed cutting equipment typically uses simple clamps to fix the pipe in place, and then performs the cutting operation using manual or electric cutting tools.

[0004] However, the aforementioned equipment cannot achieve automatic rotation and continuous feeding of the pipe, requiring frequent adjustments to the workpiece position to complete cutting at different locations, resulting in low processing efficiency. While semi-automatic cutting machine tools can achieve a certain degree of automation, their clamping mechanisms are mostly rigid fixed structures, making it difficult to adapt to the rotational requirements of the pipe during cutting. Furthermore, they lack effective obstacle avoidance designs, and the cutting blade is prone to interference with the worktable, affecting processing safety and equipment lifespan. Summary of the Invention

Sleeves are fixedly connected to the left and right sides of the connecting rod, and a movable rod is slidably connected inside the sleeve.

The lower clamping block is fixedly connected to the upper end of the worktable. A spring is fixedly connected inside the sleeve, and the lower end of the spring is fixedly connected to the upper end of the movable rod.

[0009] Preferably, an arc-shaped groove is provided on one end face of the upper clamping block and the lower clamping block opposite to each other, and an installation hole is provided on the inner wall of the arc-shaped groove, and a roller is rotatably connected inside the installation hole.

[0010] Preferably, the roller sidewall is fitted with an anti-slip sleeve, which is made of rubber material.

[0011] Preferably, the rotating fixing mechanism includes a movable seat, which is slidably connected inside the limiting groove.

[0013] Preferably, a controller is fixedly connected to the upper right side of the workbench.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves automatic rotation and precise feeding of fire hydrant pipes by setting a rotating fixing mechanism for rotating and fixing the pipes and a feeding mechanism for feeding the pipes. This allows the cutting blade to complete continuous circumferential cutting during pipe rotation, achieving efficient cutting without manual adjustment of the workpiece position, and significantly improving processing efficiency and cut smoothness.

[0015] 2. This invention, by setting a limiting mechanism on the side wall of the cutting mechanism, uses the upper and lower clamping blocks driven by springs to automatically and elastically clamp and fix the fire hydrant pipe during cutting. This ensures the stability of the cutting process, adapts to the rotation requirements of the pipe through the roller structure, avoids damage to the pipe surface caused by rigid clamping, and realizes the linkage between the clamping action and the cutting action, thereby improving operational safety.

[0016] 3. This invention creates a clearance hole on the worktable and positions the cutting blade directly above the clearance hole, allowing the blade to extend downwards into the clearance hole during the cutting process. This effectively avoids direct contact and interference between the cutting blade and the worktable, protecting both the worktable and the cutting blade, and extending the service life of the equipment. In addition, the sliding connection structure of the limiting groove and the moving seat enables precise control of the pipe cutting position. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1-6 As shown, the present invention has the following three specific embodiments. Example 1

[0021] A workpiece processing device for fire hydrant production includes a workbench 1. A limiting groove 11 and a clearance hole 12 are formed on the upper surface of the workbench 1. The limiting groove 11 is located to the right of the clearance hole 12. A support frame 13 is fixedly connected to the upper left side of the workbench 1. A cutting mechanism 2 is provided at the end of the support frame 13. The cutting mechanism 2 is used to cut the fire hydrant pipe. A limiting mechanism 3 is provided on the side wall of the cutting mechanism 2. The limiting mechanism 3 is used to fix the fire hydrant pipe during cutting. Also includes: Rotary fixing mechanism 4 is installed inside the limiting groove 11 and is used to drive the fire hydrant pipe to rotate. Feeding mechanism 5 is installed inside the limiting groove 11. Feeding mechanism 5 is used to drive the rotating fixing mechanism 4 to move inside the limiting groove 11. The cutting mechanism 2 includes an electric telescopic rod 21, which is fixedly connected to the end of the support frame 13. The telescopic end of the electric telescopic rod 21 is fixedly connected to a cutting motor 22, and the output shaft end of the cutting motor 22 is fixedly connected to a cutting blade 23. The cutting blade 23 is located directly above the clearance hole 12. The limiting mechanism 3 includes a connecting rod 31, which is fixedly connected to the telescopic rod side wall of the electric telescopic rod 21. Sleeves 32 are fixedly connected to the left and right sides of the connecting rod 31 respectively. A moving rod 33 is slidably connected inside the sleeve 32. An upper clamping block 34 is fixedly connected to the lower end of the moving rod 33. A lower clamping block 35 is provided directly below the upper clamping block 34. The lower clamping block 35 is fixedly connected to the upper end of the worktable 1. A spring 321 is fixedly connected inside the sleeve 32. The lower end of the spring 321 is fixedly connected to the upper end of the moving rod 33. An arc-shaped groove is provided on one end face of the upper clamping block 34 and the lower clamping block 35, and an installation hole 36 is provided on the inner wall of the arc-shaped groove. A roller 37 is rotatably connected inside the installation hole 36. The side wall of roller 37 is fitted with an anti-slip sleeve, which is made of rubber.

[0022] In this embodiment, as Figures 1-4As shown, during operation, one end of the fire hydrant pipe to be cut is first fixed by the rotating fixing mechanism 4, and the rotating fixing mechanism 4 is started to rotate the pipe synchronously. Then, the feeding mechanism 5 is started to drive the rotating fixing mechanism 4 to move to the left within the limiting groove 11, so that the pipe to be cut is moved directly below the cutting blade 23. Next, the electric telescopic rod 21 is started to extend downward, driving the cutting motor 22 and the cutting blade 23 to descend synchronously. At the same time, the connecting rod 31 moves downward with the telescopic rod 21, so that the upper clamping block 34 gradually approaches the lower clamping block 35. When the cutting blade 23 approaches the pipe surface, the upper clamping block 34 and the lower clamping block 35 elastically clamp and fix the pipe under the action of the spring 321. The roller 37 rotates with the pipe as it rotates, which ensures the clamping stability without affecting the pipe rotation. The cutting blade 23 continues to descend, passes through the pipe and extends into the clearance hole 12, completing the circumferential cutting operation while the pipe continues to rotate. After the cutting is completed, the electric telescopic rod 21 retracts upward, causing the cutting blade 23 to disengage from the pipe. At the same time, the upper clamping block 34 is lifted upward under the reset action of the spring 321 to release the clamp, thus completing the pipe cutting. Example 2

[0023] The difference from Embodiment 1 is that this embodiment discloses the specific structure of the rotating fixing mechanism 4 and the feeding mechanism 5; The rotating fixing mechanism 4 includes a movable seat 41, which is slidably connected inside the limiting groove 11. A support plate 42 is fixedly connected to the upper left side of the movable seat 41. A gripper 43 is rotatably connected to the left side of the support plate 42. A rotary motor 44 is fixedly connected to the upper end of the movable seat 41. The output shaft end of the rotary motor 44 is fixedly connected to the right end of the gripper 43. The feeding mechanism 5 includes a threaded rod 51, which is rotatably connected inside the limiting groove 11. The threaded rod 51 passes through the movable seat 41 and is threadedly connected thereto. The right end of the worktable 1 is fixedly connected to the feeding motor 52, and the output shaft end of the feeding motor 52 is fixedly connected to the right end of the threaded rod 51.

[0024] In this embodiment, as Figures 5-6 As shown, during operation, one end of the fire hydrant pipe to be cut is first fixed by the gripper 43. The rotary motor 44 is started to drive the gripper 43 and the pipe to rotate synchronously. Then, the feed motor 52 is started to drive the threaded rod 51 to rotate. The threaded engagement between the threaded rod 51 and the moving seat 41 causes the moving seat 41 to move to the left within the limiting groove 11, thereby driving the rotating fixing mechanism 4 and the entire pipe to feed towards the cutting position, so that the pipe to be cut is moved directly below the cutting blade 23. This facilitates the cutting mechanism 2 to cut the pipe. Example 3

[0025] The difference from Embodiment 2 is that this embodiment discloses a controller 6; A controller 6 is fixedly connected to the upper right side of the workbench 1.

[0026] In this embodiment, as Figure 1 As shown, the controller 6 can control the electric telescopic rod 21, the cutting motor 22, the rotary motor 44 and the feed motor 52 respectively, thereby controlling the start-stop and running status of each component in different operations and realizing the automated control of the cutting process.

[0027] The working principle of this invention is as follows: First, one end of the fire hydrant pipe to be cut is fixed by the clamp 43. The controller 6 starts the rotary motor 44, which drives the clamp 43 and the pipe to rotate synchronously. Then, the controller 6 starts the feed motor 52, which drives the threaded rod 51 to rotate. The threaded engagement between the threaded rod 51 and the moving seat 41 causes the moving seat 41 to move to the left within the limit groove 11, thereby driving the rotating fixing mechanism 4 and the entire pipe to feed towards the cutting position, so that the pipe to be cut is directly below the cutting blade 23. Next, the controller 6 starts the electric telescopic rod 21 to extend downward, and at the same time starts the cutting motor 22 to drive the cutting blade 23 to rotate. The electric telescopic rod 21 drives the cutting motor 22 and the cutting blade 23 to descend synchronously. The connecting rod 31 moves downward together with the telescopic rod 21, so that the upper clamp 34 gradually approaches the lower clamp 35. When the cutting blade 23 approaches the pipe surface, the upper clamp 34 and the lower clamp 35 elastically clamp and fix the pipe under the action of the spring 321. The roller 37 rotates with the pipe as it rotates, which ensures clamping stability without affecting the pipe rotation. The cutting blade 23 continues to descend, passing through the pipe and extending into the clearance hole 12, completing the circumferential cutting operation while the pipe continues to rotate. After cutting, the controller 6 controls the electric telescopic rod 21 to retract upward, causing the cutting blade 23 to disengage from the pipe. At the same time, the upper clamping block 34 is lifted upward by the spring 321 to release the clamp, the cutting motor 22 stops running, the feed motor 52 drives the threaded rod 51 to rotate in the opposite direction, causing the moving seat 41 to move to the right and reset. Finally, the rotary motor 44 stops running, and the cut pipe can be removed.

[0028] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
