Description

Technical Field

[0001] This utility model relates to the technical field of pipe conveying mechanisms for beveling machines, and more specifically, to an internally rotating pipe beveling machine. Background Technology

[0002] The internal rotation pipe beveling machine is a specialized piece of equipment that uses a rotating cutter to cut the pipe end face to achieve beveling. It features a compact structure, flexible operation, high processing precision, and outstanding efficiency, and is suitable for beveling large-diameter, thick-walled pipes in industries such as natural gas, petroleum, chemical, and power.

[0003] Currently, commonly used internal rotation pipe beveling machines are not convenient for positioning and conveying pipes with different lengths and inner diameters, thus reducing processing quality. For example, the internal rotation pipe beveling machine disclosed in publication number CN 119407561 A includes a base and a rotating base. The rotating base is rotatably connected to the base. A convex shaft is welded and fixed at the center of one side wall of the rotating base. A beveling mechanism is provided on the outer wall of the convex shaft. An internal rotation positioning mechanism is provided at one end of the convex shaft along the length direction.

[0004] As can be seen from the above-disclosed scheme, the internal rotation pipe beveling machine positions the pipe from the inside through the internal rotation positioning mechanism. However, it may not be applicable when positioning pipes of different lengths and inner diameters. Moreover, the stability of the pipe transport after positioning is insufficient, which may cause the pipe processing end to shake, thereby reducing the processing quality. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an internal rotation pipe beveling machine. This internal rotation pipe beveling machine, through the setting of a V-shaped plate, guide groove, push block, threaded pipe, lead screw and motor, can not only quickly position pipes of different lengths and inner diameters, but also accurately control their processing length, thus improving the applicability. Furthermore, through the setting of an electric telescopic rod, lifting seat, limit block, limit groove and second ball, the liftable limit block can limit pipes of different inner diameters, preventing them from moving up and down, while not affecting their axial movement, thus improving the processing quality.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An internal rotation pipe beveling machine includes a beveling machine body. A V-shaped plate is fixedly connected to the inner wall of the beveling machine body. The V-shaped plate and the inner wall of the beveling machine body enclose a guide groove. A pipe is movably connected to the inner wall of the guide groove. A pushing mechanism is movably connected to one end of the pipe. A limiting mechanism is movably connected to the surface of the pipe. Scale lines are evenly distributed along the length of the beveling machine body. A support leg is fixedly connected to the bottom of the beveling machine body. This internal rotation pipe beveling machine, through the setting of the V-shaped plate, guide groove, pushing block, threaded pipe, lead screw, and motor, can not only quickly position pipes of different lengths and inner diameters, but also accurately control their processing length, thus improving its applicability. Furthermore, through the setting of an electric telescopic rod, lifting seat, limiting block, limiting groove, and second ball bearing, the liftable limiting block can limit pipes of different inner diameters, preventing them from moving up and down without affecting their axial movement, thereby improving processing quality.

[0008] Furthermore, the pushing mechanism includes a pushing block, the side of which is slidably connected to the inner wall of the guide groove. A threaded tube is fixedly connected to the surface of the pushing block, one end of which has a threaded hole. A lead screw is threadedly connected to the inner wall of the threaded hole, and a motor is fixedly connected to one end of the lead screw. The pushing block controls its extension and retraction position through the thread, ensuring the accuracy of the axial movement position of the pipe.

[0009] Furthermore, the limiting mechanism includes a support rod, one end of which is fixedly connected to the surface of the beveling machine body, and the other end of which is fixedly connected to a fixing plate. An electric telescopic rod is fixedly connected to the surface of the fixing plate, and one end of the electric telescopic rod is fixedly connected to a lifting seat. The lifting seat can move up and down under the drive of the electric telescopic rod, which facilitates limiting pipes with different inner diameters.

[0010] Furthermore, one end of the lifting seat is provided with a folded edge, and a limiting block is fixedly connected to the bottom of the lifting seat. A limiting groove is opened at the bottom of the limiting block, and a second ball is engaged in the inner wall of the limiting groove. The surface of the second ball is in rolling contact with the surface of the pipe, which can restrict the upward movement of the pipe without affecting its axial movement.

[0011] Furthermore, the guide groove has a V-shaped cross-section, and a first ball bearing is engaged with the inner wall of the guide groove. The surface of the first ball bearing is in rolling contact with the surface of the pipe, which reduces the frictional resistance between the pipe and the guide groove.

[0012] Furthermore, one end of the push block is provided with a right-angle groove and a boss, and a pointer is fixedly connected to the side of the boss. The pointer and scale lines make it easy for users to see the movement size of the pipe intuitively.

[0013] Furthermore, the push block has a clearance groove on its side, which serves to prevent air from entering.

[0014] Compared with existing technologies, the advantages of this utility model are: (1) This solution, through the V-shaped plate, guide groove, push block, threaded pipe, screw and motor, can not only quickly position pipes of different lengths and inner diameters, but also accurately control their processing length, thus improving the scope of application.

[0015] (2) This solution uses an electric telescopic rod, lifting seat, limit block, limit groove and second ball to limit pipes of different inner diameters, prevent them from moving up and down, and at the same time does not affect their axial movement, thus improving the processing quality.

[0019] Please see Figure 1-5The internal rotation pipe beveling machine includes a beveling machine body 1. One end of the beveling machine body 1 is equipped with a liftable cutting tool for processing pipes 4 of different inner diameters. A V-shaped plate 11 is fixedly connected to the inner wall of the beveling machine body 1. The V-shaped plate 11 and the inner wall of the beveling machine body 1 together form a guide groove 12. A pipe 4 is movably connected to the inner wall of the guide groove 12. A pushing mechanism 2 is movably connected to one end of the pipe 4. The pushing mechanism 2 includes a pushing block 21. The side of the pushing block 21 is slidably connected to the inner wall of the guide groove 12. A threaded pipe 26 is fixedly connected to the surface of the pushing block 21. A threaded hole 27 is opened at one end of the threaded pipe 26. A lead screw 28 is threadedly connected to the inner wall of the threaded hole 27. A motor 29 is fixedly connected to one end of the lead screw 28. The pushing block 21 is controlled by the threaded mechanism. The extension and retraction position is controlled to ensure the accuracy of the axial movement position of the pipe 4. The surface of the pipe 4 is movably connected to the limiting mechanism 3. The limiting mechanism 3 includes a support rod 32. One end of the support rod 32 is fixedly connected to the surface of the beveling machine body 1. The other end of the support rod 32 is fixedly connected to a fixing plate 31. The surface of the fixing plate 31 is fixedly connected to an electric telescopic rod 33. One end of the electric telescopic rod 33 is fixedly connected to a lifting seat 34. The lifting seat 34 can move up and down under the drive of the electric telescopic rod 33, which is convenient for limiting the pipe 4 with different inner diameters. The surface of the beveling machine body 1 has scale lines 13. The scale lines 13 are evenly distributed along the length direction of the beveling machine body 1. The bottom of the beveling machine body 1 is fixedly connected to a support leg 14.

[0020] One end of the lifting seat 34 is provided with a folded edge 35. The bottom of the lifting seat 34 is fixedly connected to a limiting block 36. The bottom of the limiting block 36 has a limiting groove 37. The inner wall of the limiting groove 37 is engaged with a second ball 38. The surface of the second ball 38 is in rolling contact with the surface of the pipe 4, which can restrict the upward movement of the pipe 4 without affecting its axial movement. The cross-sectional shape of the guide groove 12 is V-shaped. The inner wall of the guide groove 12 is engaged with a first ball 15. The surface of the first ball 15 is in rolling contact with the surface of the pipe 4, which reduces the frictional resistance between the pipe 4 and the guide groove 12.

[0021] One end of the push block 21 is provided with a right-angle groove 22 and a boss 24. A pointer 25 is fixedly connected to the side of the boss 24. The pointer 25 and the scale line 13 make it easy for the user to see the movement size of the pipe 4. A clearance groove 23 is opened on the side of the push block 21. The clearance groove 23 has the function of clearance.

[0022] When using this internal rotation pipe beveling machine, the pipe 4 is first placed directly in the V-shaped guide groove 12, with the left end of the pipe 4 positioned to the right of the push block 21. Then, the electric telescopic rod 33 is controlled to extend downwards, causing the lifting seat 34 to drive the limiting block 36 to press down on the surface of the pipe 4, thus preventing it from moving up and down. Then, the motor 29 is controlled to rotate forward, causing the lead screw 28 to rotate clockwise. The clockwise rotation of the lead screw 28 pushes the threaded pipe 26 to the right under the action of the thread. The movement of the threaded pipe 26 to the right drives the push block 21 to push the pipe 4 to the right. At the same time, the movement of the push block 21 to the right drives the pointer 25 to move to the right. The operator ensures the processing position of the pipe 4 by observing the movement scale of the pointer 25.
