[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. Steel pipes are one of the main components of steel structures. After production, steel pipes are often chamfered at the ends according to actual usage requirements; a chamfering device is the equipment used to chamfer the ends of the steel pipes.

[0003] Chinese utility model patent CN215469721U discloses a pipe end chamfering device, including a body, an operating table fixedly connected to the top of the body, a motor base fixedly connected to the inner bottom wall of the operating table, a servo motor fixedly connected to the inner wall of the motor base, a lead screw fixedly connected to the output end of the servo motor, a limit block threadedly connected to the outer wall of the lead screw, a support plate fixedly connected to the top of the limit block, a connecting rod fixedly connected to the top of the support plate, and a moving plate fixedly connected to the top of the connecting rod. By incorporating a servo motor, lead screw, limit block, support plate, connecting rod, moving plate, pipe placement seat, L-shaped support frame, electric push rod, and clamping plate, this device avoids the inconvenience of manual pipe loading, is simple to operate, and has a high degree of automation. It achieves the effect of automatically loading and unloading pipes. However, the existing pipe end chamfering device's clamp does not have a rotation function. When both ends of the pipe need to be chamfered, the chamfering device first chamfers one end of the pipe, then disassembles the pipe and turns it around to re-clamp the pipe to chamfer the other end. Frequent disassembly and reassembly of the pipe reduces processing efficiency.

[0004] Therefore, this utility model provides a steel structure pipe end chamfering device to solve the above problems. Utility Model Content

[0005] This utility model provides a steel structure pipe end chamfering device, which aims to solve the problems of existing pipe end chamfering devices in the background art, such as the clamps not having a rotation function, the chamfering device first chamfering one end of the pipe, then disassembling the pipe and turning it around to chamfer the other end when both ends of the pipe need to be chamfered, and the frequent disassembly and reassembly of the pipe reduces processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure pipe end chamfering device, including a workbench, a servo motor mounted on the front of the workbench and a mounting base disposed on the end face of the workbench, a lead screw disposed on the drive end of the servo motor, a moving block connected to the lead screw by a thread, a rotating structure mounted on the end face of the moving block, a clamp mounted on the rotating structure, and a chamfering machine and a protective structure disposed on the mounting base by a connecting hole;

[0007] The rotating structure includes a fixed plate mounted on the end face of the moving block, a U-shaped frame mounted on the end face of the fixed plate, a rotating cylinder rotatably mounted on the U-shaped frame via a limiting annular groove, and a rotating cylinder disposed on the end face of the inner cavity of the U-shaped frame. A rotating plate is mounted on the output end of the rotating cylinder. By setting up the rotating structure, after chamfering one end of the pipe, the pipe is rotated 180 degrees before chamfering the other end of the pipe. This avoids the problems of existing pipe end chamfering devices where the clamps do not have a rotation function, and when both ends of the pipe need to be chamfered, the chamfering device first chamfers one end of the pipe, then disassembles the pipe and turns it around to re-clamp the pipe to chamfer the other end. This eliminates the need for frequent disassembly and reassembly of the pipe, thereby improving the pipe processing efficiency.

[0008] Preferably, the protective structure includes L-shaped plates symmetrically installed on the front of the mounting base, with two sets of L-shaped plates slidably mounted on a protective cover. A fixed shell is installed on the end face of the protective cover, and insertion rods are slidably installed on the front and rear sides of the fixed shell through connecting holes. A ring plate and a pull ring at the front end of the insertion rod are installed on the outer wall of the insertion rod and inside the fixed shell. A spring is installed on the ring plate and on the outer wall of the insertion rod.

[0009] Preferably, the clamp includes a clamping plate and a support frame mounted on the end face of the rotating plate. The support frame is fitted with a screw through a threaded hole, and a pressure plate is rotatably mounted on the lower end of the screw. The left and right side walls of the support frame are provided with through grooves that are slidably connected to the pressure plate.

[0010] Preferably, the worktable is rotatably connected to the end of the lead screw away from the servo motor via a bearing, and an installation groove is provided on the worktable corresponding to the lead screw. T-shaped plates are symmetrically installed on the bottom of the fixed plate, and a T-shaped groove is provided on the worktable that is slidably connected to the T-shaped plates.

[0011] Preferably, the upper end of the rotating cylinder is connected to the bottom of the rotating plate, and the rotation range of the rotating cylinder is 180 degrees.

[0012] Preferably, the mounting base has a limiting hole adapted to the insertion rod, and the protective cover has a workpiece hole corresponding to the clamp.

[0013] Preferably, the inner wall of the fixed shell is slidably connected to the ring plate, and the inner cavity of the fixed shell is connected to the end of the spring away from the ring plate.

[0014] Beneficial effects: By setting up a rotating structure and using a U-shaped frame, rotating cylinder, rotating plate and rotating cylinder in combination, after chamfering one end of the pipe, the pipe is rotated 180 degrees and then chamfered at the other end. This avoids the problems of existing pipe end chamfering devices where the clamps do not have a rotating function, and when both ends of the pipe need to be chamfered, the chamfering device first chamfers one end of the pipe, then disassembles the pipe and turns it around to re-clamp the pipe to chamfer the other end. This eliminates the need for frequent disassembly and reassembly of the pipe, thereby improving the efficiency of pipe processing. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] This embodiment provides a steel structure pipe end chamfering device, such as... Figures 1-6 As shown, the chamfering device includes a worktable 1, a servo motor 2 mounted on the front of the worktable 1 and a mounting base 7 set on the end face of the worktable 1, a lead screw 3 set on the drive end of the servo motor 2, a moving block 4 connected to the lead screw 3 by a thread, a rotating structure 5 mounted on the end face of the moving block 4, a clamp 6 mounted on the rotating structure 5, and a chamfering machine 8 and a protective structure 9 set on the mounting base 7 are mounted on the mounting base 7 through a connecting hole.

[0025] The rotating structure 5 includes a fixed plate 51 installed on the end face of the movable block 4, a U-shaped frame 52 installed on the end face of the fixed plate 51, a rotating cylinder 55 rotatably installed on the U-shaped frame 52 through a limiting ring groove 521, and a rotating cylinder 53 disposed on the end face of the inner cavity of the U-shaped frame 52, and a rotating plate 54 installed on the output end of the rotating cylinder 53.

[0026] In use, the clamp 6 is used to fix the tube body, and the servo motor 2 is started to rotate forward. The servo motor 2 drives the lead screw 3 to rotate, and the lead screw 3 drives the moving block 4 to move in the opposite direction closer to the chamfering machine 8. The moving block 4 moves the rotating structure 5, and the rotating structure 5 carries one end of the tube body on the clamp 6 to contact the cutting tool of the chamfering machine 8 to chamfer one end of the chamfering machine 8. After the chamfering is completed, the servo motor 2 is driven to rotate in reverse, and the lead screw 3 drives the moving block 4 to move away from the chamfering machine 8, so that one end of the tube body is away from the cutting tool of the chamfering machine 8. The rotary cylinder 53 is started to rotate, and the rotary cylinder 53 drives the rotating plate 54 to rotate 180 degrees. The rotating plate 54 carries the tube body on the clamp 6 to rotate. A 180-degree rotation is performed, essentially turning the tube around. This drives the servo motor 2 to rotate forward, causing the moving block 4 to move along with the rotating structure 5. The rotating structure 5 then brings the other end of the tube on the clamp 6 into contact with the cutting tool of the chamfering machine 8, chamfering the other end of the chamfering machine 8. This allows for chamfering both ends of the tube without frequent disassembly and reassembly, avoiding the problems of existing pipe end chamfering devices where the clamps lack rotational functionality. When both ends of the tube need chamfering, the chamfering device first chamfers one end, then disassembles and reassembles the tube to chamfer the other end. This eliminates the need for frequent disassembly and reassembly, thus improving pipe processing efficiency.

[0027] In this embodiment, the clamp 6 includes a clamping plate 61 and a support frame 62 installed on the end face of the rotating plate 54. The support frame 62 is equipped with a screw 63 through a threaded hole. A pressure plate 64 is rotatably installed on the lower end of the screw 63. The left and right side walls of the support frame 62 are provided with through grooves 621 that are slidably connected to the pressure plate 64.

[0028] In this process, by setting the clamp 6, one end of the pipe is passed through the clamp 61 and the pressure plate 64 and placed on the inner wall of the clamp 61. Then, the drive screw 63 moves down and brings the pressure plate 64 closer to the position of the pipe body, so that the pressure plate 64 contacts the outer wall of the pipe body and applies a certain pressure to achieve the function of fixing the pipe body.

[0029] In this embodiment, the worktable 1 is rotatably connected to the end of the lead screw 3 away from the servo motor 2 via a bearing. The worktable 1 is provided with a mounting groove 101 corresponding to the lead screw 3. T-shaped plates 10 are symmetrically installed on the bottom of the fixed plate 51. The worktable 1 is provided with a T-shaped groove 102 that is slidably connected to the T-shaped plate 10. The upper end of the rotating cylinder 55 is connected to the bottom of the rotating plate 54. The rotation range of the rotating cylinder 53 is 180 degrees.

[0030] With the T-slots 102 and T-plates 10 in place, when the moving block 4 moves with the fixed plate 51, the fixed plate 51 slides with the two sets of T-plates 10 in the T-slots 102 on both sides, thereby providing stable support for the fixed plate 51 and improving the stability of the fixed plate 51.

[0031] Example 2

[0032] Unlike Embodiment 1, the protective structure 9 includes L-shaped plates 91 symmetrically installed on the front of the mounting base 7. The two sets of L-shaped plates 91 are slidably mounted with a protective cover 92. A fixed shell 93 is installed on the end face of the protective cover 92. Insert rods 94 are slidably installed on the front and rear sides of the fixed shell 93 through connecting holes. A ring plate 95 and a pull ring 97 are installed on the outer wall of the insert rod 94 and inside the fixed shell 93. A spring 96 is installed on the ring plate 95 and on the outer wall of the insert rod 94.

[0033] When the chamfering machine 8 is used to chamfer the tube, iron filings will fly everywhere. If the iron filings hit the workers, they will cause some injury. The transparent protective cover 92 covers the outside of the chamfering tool and the chamfered end of the tube. The lower end of the protective cover 92 is connected to the end face of the worktable 1, so that the flying iron filings are blocked by the protective cover 92 and will not hit the workers, thus protecting the workers. After the chamfering device is stopped, the workers can pull the pull ring 97 outward. The pull ring 97 moves the insertion rod 94 through the limit hole 71, and then move the protective cover 92 upward, so that the protective cover 92 can be quickly removed. At this time, the iron filings on the end face of the worktable 1 can be cleaned. After cleaning the iron filings, the protective cover 92 can be installed in its original position, so that the chamfering device can be used more effectively.

[0034] In this embodiment, the mounting base 7 is provided with a limiting hole 71 that is adapted to the insertion rod 94, and the protective cover 92 is provided with a workpiece hole 921 corresponding to the clamp 6; the inner wall of the fixing shell 93 is slidably connected to the ring plate 95, and the inner cavity of the fixing shell 93 is connected to the end of the spring 96 away from the ring plate 95.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
