Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and more specifically, it relates to a pneumatic pipe cutting and fixing fixture for steel pipe assemblies. Background Technology

[0002] In steel pipe processing and cutting operations, it is crucial to quickly and safely fix the steel pipes in the appropriate position. Traditional fixing methods usually rely on manual operation and basic clamps. These clamps often lack the function of quick clamping and disassembly, and there may be unstable factors during the fixing process. This fixing method is not only time-consuming and inconvenient, but also requires operators to spend extra time and effort to adjust when frequently disassembling and replacing steel pipes, which reduces work efficiency. In the steel pipe production process, the requirements for the reliability and ease of operation of clamps are gradually increasing, and existing technologies have certain shortcomings in this regard.

[0003] Furthermore, traditional clamps often fail to ensure the stability of steel pipes during the cutting process, especially under the influence of high-pressure pneumatic tools. The steel pipes may experience slight displacement or vibration, affecting cutting accuracy and safety. Because these clamping devices use relatively primitive methods and are inconvenient to disassemble, a significant amount of time is wasted each time a steel pipe is replaced or adjusted. This situation is particularly prominent in scenarios requiring large-scale cutting and processing of steel pipes, severely impacting work efficiency and product quality. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a pneumatic pipe cutting and fixing tool for steel pipe assembly to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic pipe cutting and fixing fixture for steel pipe assemblies, comprising a support frame, on which a fixing mechanism is provided. The fixing mechanism includes a support plate, an outer sleeve, sliding rods, sliders, mounting plates, telescopic springs, clamps, sliding grooves, sliding sleeves, push sleeves, and a limiting mechanism. Multiple sets of support plates are fixed to the support frame, the outer sleeve is fixed between multiple sets of support plates, multiple sets of sliding rods are fixed inside the fixing sleeve, the sliders slide on the outer walls of multiple sets of sliding rods, the mounting plates are fixed inside multiple sets of sliders, and the telescopic springs are fixed inside multiple sets of mounting plates. The clamping plate is provided with multiple sets of clamps, which are respectively fixed to the top of multiple sets of telescopic springs. Multiple sets of sliding grooves are provided on the outer wall of the fixed sleeve. The sliding sleeve slides in multiple sets of sliding grooves. The push sleeve is fixed on the inner wall of the sliding sleeve. The limiting mechanism includes a connecting sleeve, a mounting block, an arc rod, a rotating sleeve, a support rod, and a sliding hole. The connecting sleeve is fixed on the bottom surface of the sliding sleeve. Multiple sets of mounting blocks are provided on the outer wall of the connecting sleeve. Multiple sets of arc rods are provided on the outer wall of the multiple sets of mounting blocks. The rotating sleeve rotates on the outer wall of the fixed sleeve. Multiple sets of support rods are provided on the outer wall of the rotating sleeve. The sliding hole is provided on the outer wall of the multiple sets of support rods and is respectively inserted into the multiple sets of sliding holes.

[0008] This invention is further configured such that side strips are fixedly provided on the outer walls of multiple sets of sliding rods, and the multiple sets of side strips are slidably connected to multiple sets of sliders. The sliding cooperation between the side strips and the sliders plays a guiding role, ensuring that the sliders maintain a stable trajectory when moving on the sliding rods, preventing deviation, and improving the stability of the structure during clamping.

[0009] This invention is further configured such that limiting blocks are fixedly provided on the outer walls of multiple sets of clamping plates, and the multiple sets of limiting blocks are slidably connected to multiple sets of mounting plates respectively; rubber pads are fixedly provided on the inner walls of multiple sets of clamping plates. The limiting blocks restrict the movement range of the clamping plates to avoid over-clamping or displacement, while the rubber pads provide flexible contact and high friction, effectively protecting the surface of the tube and enhancing the fixing effect.

[0010] The present invention is further configured such that a top plate is fixedly provided at one end of the support frame, a compression spring is connected to the outer wall of the top plate, and an abutment plate is fixedly provided at the top of the compression spring. Under the action of the compression spring, the abutment plate forms a pre-compression on the steel pipe, stabilizing its position and providing reliable initial support for subsequent clamping, thereby improving the overall fixing efficiency.

[0011] The present invention is further configured such that a limiting rod is fixedly provided inside the fixed sleeve, and multiple sets of the limiting rod are provided, all of which are slidably connected to the push sleeve. The sliding cooperation between the limiting rod and the push sleeve can limit the movement range of the push sleeve, prevent its misalignment or displacement, thereby ensuring the accuracy and repeatability of the clamping action.

[0012] The present invention is further configured such that a pop-out spring is connected to the inner wall of the fixed sleeve, and a push ring is connected to the bottom end of the pop-out spring. The pop-out spring and the push ring cooperate to form an automatic reset mechanism, which can push the clamping mechanism to automatically return to the initial state after the clamping is released, simplifying the operation steps and improving the disassembly efficiency.

[0013] The present invention is further configured such that a push spring is connected to the bottom surface of the connecting sleeve, and a thrust bearing is connected between the top end of the push spring and the rotating sleeve. The push spring provides elastic force to assist in positioning, while the thrust bearing reduces frictional resistance during rotation, making the rotating sleeve rotate more smoothly and facilitating the efficient completion of clamping and releasing actions.

[0014] The present invention is further configured such that the inner wall of the rotating sleeve is provided with a movable groove, the movable groove is provided with multiple sets and the inner wall is connected with a compression spring, the bottom end of each of the multiple sets of compression springs is fixedly provided with a positioning block, the outer wall of the fixed sleeve is provided with a positioning groove, the positioning groove is provided with multiple sets and respectively engages with multiple sets of positioning blocks, and a rubber sleeve is fixedly provided on the bottom surface of the rotating sleeve.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a pneumatic pipe cutting and fixing fixture for steel pipe assemblies, which has the following advantages:

[0017] 1. The fixing mechanism, by setting multiple sets of support plates and external sleeves on the support frame, together with sliding rods, sliders, mounting plates, clamps, sliding sleeves and push sleeves, realizes the automatic clamping operation of steel pipes. When the steel pipe is inserted, the sliding sleeve drives the mounting plate and clamp to move. Under the action of the rubber pad on the outer wall of the clamp, it is tightly attached to the outer wall of the pipe, which enhances the friction and achieves stable clamping. This structure effectively simplifies the operation process, improves the efficiency of steel pipe clamping, and avoids the drawbacks of insecure clamping or manual adjustment in traditional methods.

[0018] 2. The limiting mechanism utilizes the synergistic effect between the connecting sleeve, mounting block, arc rod, rotating sleeve, and support rod, along with the sliding hole, to form a stable limiting device. By rotating the rotating sleeve, the arc rod inserts into the sliding hole to complete the limiting, ensuring that the position of the clamping structure remains unchanged during operation and preventing the risks caused by slippage or loosening. This mechanism makes the fixing action more precise and reliable, ensuring the stability and safety of operation without affecting the clamping force, and improving the overall operational controllability.

[0019] 3. The positioning structure relies on the compression spring, positioning block, and positioning groove on the outer wall of the fixed sleeve. By rotating the rotating sleeve, the positioning block is engaged in the positioning groove to achieve accurate positioning and prevent the clamping mechanism from shifting at an angle during use. When disassembly is required, the positioning block can be released through the movable groove, and automatic reset can be achieved with the help of the pop-out spring and push ring, thereby releasing the clamp. This structure has good self-resetting performance and convenient operation, which significantly improves the efficiency and accuracy of repeated positioning in the steel pipe loading and unloading process.

[0029] Please see Figures 1-5 A pneumatic pipe cutting and fixing fixture for steel pipe assemblies includes a support frame 1. A fixing mechanism is mounted on the support frame 1. The fixing mechanism includes a support plate 2, an outer sleeve 3, sliding rods 4, sliders 5, mounting plates 6, telescopic springs 7, clamping plates 8, sliding grooves 9, sliding sleeves 10, push sleeves 11, and a limiting mechanism. Multiple sets of support plates 2 are fixed to the support frame 1. The outer sleeve 3 is fixed between multiple sets of support plates 2. Multiple sets of sliding rods 4 are fixed inside the fixing sleeve. The sliders 5 slide on the outer walls of the multiple sets of sliding rods 4. The mounting plates 6 are fixed inside the multiple sets of sliders 5. The telescopic springs 7 are fixed inside the multiple sets of mounting plates 6. Multiple sets of clamping plates 8 are respectively fixed to the tops of the multiple sets of telescopic springs 7. Multiple sets of sliding grooves 9 are provided on the outer wall of the fixed sleeve. The sliding sleeve 10 slides within the multiple sets of sliding grooves 9. The push sleeve 11 is fixed on the inner wall of the sliding sleeve 10. The limiting mechanism includes a connecting sleeve 12, a mounting block 13, an arc rod 14, a rotating sleeve 15, a support rod 16, and a sliding hole 17. The connecting sleeve 12 is fixed on the bottom surface of the sliding sleeve 10. Multiple sets of mounting blocks 13 are provided on the outer wall of the connecting sleeve 12. Multiple sets of arc rods 14 are provided and fixed on the outer wall of the multiple sets of mounting blocks 13. The rotating sleeve 15 rotates on the outer wall of the fixed sleeve. Multiple sets of support rods 16 are provided and fixed on the outer wall of the rotating sleeve 15. The sliding hole 17 is provided on the outer wall of the multiple sets of support rods 16 and is respectively inserted into the multiple sets of sliding holes 17.

[0030] Each of the multiple sets of slide bars 4 has a side strip 18 fixedly installed on its outer wall, and the multiple sets of side strips 18 are slidably connected to multiple sets of sliders 5. Through the sliding cooperation between the side strips 18 and the sliders 5, the sliders 5 can slide stably on the slide bars 4, avoiding deviation or jamming, thereby making the clamping process more stable and improving the accuracy and reliability of the fixing effect.

[0031] Each set of clamping plates 8 has a limiting block 19 fixedly installed on its outer wall. The limiting blocks 19 are slidably connected to each set of mounting plates 6. Each set of clamping plates 8 has a rubber pad 20 fixedly installed on its inner wall. The limiting blocks 19 are slidably connected to the mounting plates 6 to ensure that the clamping plates 8 do not move excessively or loosen when clamped. The rubber pads 20 provide sufficient friction to effectively clamp the tube body while reducing damage to the tube body surface and enhancing the fixing effect.

[0032] A top plate 21 is fixedly provided at one end of the support frame 1. A compression spring 22 is connected to the outer wall of the top plate 21, and an abutment plate 23 is fixedly provided at the top of the compression spring 22. Under the action of the compression spring 22, the abutment plate 23 provides initial support for the tube body, ensuring that the tube body is stably placed in the clamping position. The spring elasticity adapts to different tube body sizes, enhancing the overall clamping stability.

[0033] A limiting rod 24 is fixedly provided inside the fixed sleeve. Multiple sets of limiting rods 24 are provided, and all of them are slidably connected to the push sleeve 11. By sliding with the push sleeve 11, the limiting rod 24 restricts the range of motion of the push sleeve 11, ensuring that the push sleeve will not deviate or become unstable during the clamping process, which helps to achieve more precise clamping and positioning.

[0034] A spring 25 is connected to the inner wall of the fixed sleeve, and a push ring 26 is connected to the bottom end of the spring 25. The spring 25 provides an automatic reset function. When the clamping is released, the push ring 26 can push the clamping device back to the initial state, which simplifies the disassembly operation and improves the convenience of use.

[0035] A push spring 27 is connected to the bottom surface of the connecting sleeve 12, and a thrust bearing 28 is connected between the top of the push spring 27 and the rotating sleeve 15. The push spring 27 provides elastic support during operation, helping the rotating sleeve 15 to rotate smoothly. The thrust bearing 28 reduces the friction between the rotating sleeve and the connecting sleeve, making the rotation smoother and improving the operational flexibility and durability of the clamping device.

[0036] The inner wall of the rotating sleeve 15 is provided with a movable groove 29. Multiple sets of movable grooves 29 are provided and the inner wall is connected with a compression spring 30. The bottom end of each set of compression springs 30 is fixed with a positioning block 31. The outer wall of the fixed sleeve is provided with a positioning groove 32. Multiple sets of positioning grooves 32 are provided and are respectively engaged with multiple sets of positioning blocks 31. A rubber sleeve 33 is fixedly provided on the bottom surface of the rotating sleeve 15.

[0037] In this embodiment, during use, the tube body is inserted into the outer sleeve 3, the top end of the tube body abuts against the outer wall of the abutment plate 23 and compresses the compression spring 22, pushing the sliding sleeve 10 to slide along the sliding groove 9 and pushing the multiple sets of mounting plates 6 through the push sleeve 11 so that they slide along the sliding rod 4 through the slider 5, while driving the multiple sets of clamping plates 8 to clamp the outer wall of the tube body, and the multiple sets of rubber pads 20 abut against the outer wall of the tube body to increase friction. At the same time, the multiple sets of mounting plates 6 abut against the push ring 26 and compress the compression spring 30. Then, the rotating sleeve 15 is rotated to drive the multiple sets of support rods 16 to rotate and cause the multiple sets of arc rods 14 to be inserted into the sliding hole 17. The multiple sets of compression springs 30 push the positioning block 31 to engage in the positioning groove 32 to position the rotating sleeve 15, thereby completing the fixation of the tube body.

[0038] More specifically, when the tube body needs to be disassembled, the rotating sleeve 15 is rotated, and the positioning blocks 31 are pushed to slide in the movable groove 29 through the outer wall of the multiple positioning grooves 32, which compresses the compression spring 30. This causes the multiple positioning blocks 31 to slide into the movable groove 29. The rotating sleeve 15 drives the multiple support rods 16 to rotate, causing the arc rod 14 to disengage from the sliding hole 17 and release the limitation on the sliding sleeve 10. The pop-out spring 25 is reset and pushes the push ring 26. The push ring 26 pushes the multiple mounting blocks 13 to slide along the sliding rod 4 through the slider 5, thereby causing the multiple clamping plates 8 to release the clamping and fixing of the outer wall of the tube body. Then the tube body can be taken out.

[0039] In summary, during use or operation of the overall equipment: When in use, the tube body is inserted into the outer sleeve 3, the top of the tube body abuts against the outer wall of the abutment plate 23 and compresses the compression spring 22, pushing the sliding sleeve 10 to slide along the sliding groove 9 and pushing the multiple sets of mounting plates 6 through the push sleeve 11 so that they slide along the sliding rod 4 through the slider 5, while driving the multiple sets of clamping plates 8 to clamp the outer wall of the tube body, and the multiple sets of rubber pads 20 abut against the outer wall of the tube body to increase friction. At the same time, the multiple sets of mounting plates 6 abut against the push ring 26 and compress the compression spring 30. Then, the rotating sleeve 15 is rotated to drive the multiple sets of support rods 16 to rotate and cause the multiple sets of arc rods 14 to be inserted into the sliding hole 17. The multiple sets of compression springs 30 push the positioning block 31 to engage in the positioning groove 32 to position the rotating sleeve 15, thereby completing the fixation of the tube body.

[0040] When the tube body needs to be disassembled, rotate the rotating sleeve 15, and push the positioning block 31 to slide in the movable groove 29 through the outer wall of the multiple positioning grooves 32, which will compress the compression spring 30. This will cause the multiple positioning blocks 31 to slide into the movable groove 29. The rotating sleeve 15 will drive the multiple support rods 16 to rotate, causing the arc rod 14 to disengage from the sliding hole 17 and release the limitation on the sliding sleeve 10. The pop-out spring 25 will reset and push the push ring 26. The push ring 26 will push the multiple mounting blocks 13 to slide along the sliding rod 4 through the slider 5, thereby causing the multiple clamping plates 8 to release the clamping and fixing of the outer wall of the tube body. Then the tube body can be taken out.

For all the fixed connections mentioned above, welding is preferred.
