Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial technology, specifically a steel pipe beveling device. Background Technology
[0002] Traditional processing equipment often uses a fixed-size grinding structure, which can only be adapted to steel pipes of a single specification. When faced with the need to bevel steel pipes of different diameters, it is necessary to frequently change equipment or accessories, resulting in low production efficiency and increased costs. For example, some equipment uses a fixed grinding head for processing and cannot automatically adjust the grinding range according to the diameter of the steel pipe, which limits the applicable scenarios of the equipment.
[0003] The existing equipment uses a relatively simple method to fix the steel pipe, often employing a single clamp or a manual adjustment structure. This makes it difficult to ensure the coaxiality of the steel pipe during processing. For example, some equipment relies on manually tightening bolts to fix the steel pipe, which can easily cause the steel pipe to shift due to uneven force, resulting in deviation of the bevel angle and affecting the subsequent welding quality.
[0004] An investigation revealed that a Chinese utility model patent (publication number: CN211540019U) discloses a steel pipe beveling device, comprising a central column, a first telescopic rod and a second telescopic rod on the outer side of the central column, the second telescopic rod being positioned above the first telescopic rod, a push plate connected to the end of the first telescopic rod away from the central column, and a top wheel connected to the end of the second telescopic rod away from the central column, a first motor inside the central column, a fixed plate connected to the output end of the first motor, a first support plate, a second support plate and a spline shaft inside the fixed plate, a turntable at one end of the first support plate, a first cutting gun on the turntable, racks on opposite sides of the first and second support plates, and a spline shaft meshing on the racks of the first and second support plates, a second motor connected to one end of the spline shaft, and the second motor being positioned above the fixed plate.
[0005] Although the aforementioned patent has high applicability and promotional value due to the support plate, a single clamping component cannot achieve more precise cutting and processing.
[0006] Therefore, this utility model provides a steel pipe beveling device to solve the above problems. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe beveling processing device, characterized in that it includes a base plate, the outer surface of which is rectangular, and a mounting frame is fixedly connected to the top center of the base plate. A circular hole is opened in the outer center of the mounting frame, and a hollow frame is fixedly connected to one end of the mounting frame. A grinding component is provided at the other end of the mounting frame for grinding steel pipe beveling of different sizes and models.
[0009] As a preferred technical solution of this application, a support column is fixedly connected to the top of the base plate away from the mounting frame, and a connecting column is fixedly connected to the top of the support column. The connecting column is cylindrical in shape, and a motor is fixedly installed at one end of the connecting column, with the output end of the motor fixedly connected to the outside of the connecting column.

[0011] As a preferred technical solution of this application, the hollow grinder has a set of discs rotatably connected inside, and an arc-shaped groove is opened in the center of the disc. A support column is fixedly connected between the two discs, and the outside of the support column is slidably connected inside the groove. A receiving plate is fixedly connected to the center of the outside of the disc, and the outside of the receiving plate is square.
[0012] As a preferred technical solution of this application, the outer front end of the hollow frame is fixedly connected to multiple slide rails, and the slide rails are fixedly installed with connecting rods. The hollow frame is fixedly connected to a connecting frame, and the connecting frame has holes inside.
[0013] As a preferred technical solution of this application, the slide rail is slidably connected to a rotating shaft, and the other end of the rotating shaft is fixedly connected to an arc-shaped clamp. The outer side of the arc-shaped clamp is set as a semi-circular clamp, and the top of the outer side of the arc-shaped clamp is fixedly connected to a slider.

[0015] I. Adaptive multi-specification grinding significantly improves equipment versatility
[0016] Through the sliding fit structure of the disc, support column and connecting plate inside the hollow grinder, the outer grinding block can automatically extend and retract radially. It can adapt to steel pipes of different diameters without replacing the grinding components. Compared with the traditional fixed-size grinding head, the applicable range of the equipment is expanded several times, avoiding downtime losses caused by frequent parts replacement.
[0017] II. Precise clamping and positioning to ensure the accuracy of beveling.
[0018] The combination design of the slide and the arc clamp can adjust the clamping curvature through the slider, and with the sliding positioning of the rotating shaft, the coaxiality error between the steel pipe axis and the grinding component is reduced. This design solves the problem of steel pipe offset caused by traditional manual clamping, and the uniformity of the weld penetration is significantly improved during welding.

[0027] Furthermore, the polishing assembly includes a connecting post 5, an outer polishing block 6, a hollow polisher 7, and a connecting plate 10. The outer end of the connecting post 5, away from the motor 4, is fixedly connected to the hollow polisher 7. The hollow polisher 7 is hollow inside, and a ring of holes is opened on the outside of the hollow polisher 7. The connecting plate 10 is slidably connected inside the holes. The outer polishing block 6 is fixedly connected to the outside of the connecting plate 10, and the outer polishing block 6 is arc-shaped.
[0028] Furthermore, a set of discs 8 are rotatably connected inside the hollow grinder 7, and an arc-shaped groove is provided in the center of the disc 8. A support column 9 is fixedly connected between the two discs 8, and the outside of the support column 9 is slidably connected inside the groove. A receiving plate 10 is fixedly connected to the center of the outside of the disc 8, and the outside of the receiving plate 10 is square.
[0029] Furthermore, the hollow frame 11 has multiple slide rails 12 fixedly connected to its outer front end, and connecting rods are fixedly installed inside the slide rails 12. The hollow frame 11 has a connecting frame 13 fixedly connected inside, and the connecting frame 13 has holes inside.
[0030] Furthermore, a rotating shaft 14 is slidably connected inside the slide rail 12, and an arc-shaped clamp 15 is fixedly connected to the other end of the rotating shaft 14. The arc-shaped clamp 15 is set as a semi-circular clamp, and a slider 16 is fixedly connected to the top of the arc-shaped clamp 15.

[0032] This utility model provides a steel pipe beveling device. A motor 4 is fixed to the top of a support column 3.

An outer grinding block 6 on the outside of the hollow grinder 7 is connected to the internal structure via a connecting plate 10. When the hollow grinder rotates, the outer grinding block forms a circular motion trajectory, grinding the end of the steel pipe. Two discs 8 inside the hollow grinder 7 are connected by a support column 9. An arc-shaped groove in the center of the disc allows the support column to slide radially. When steel pipes of different diameters are inserted, the outer grinding block 6 is squeezed by the outer wall of the steel pipe, pushing the connecting plate 10 to move the disc in the hollow grinding process. The grinding wheel moves inside the mill, and the support slides in the groove, causing the outer grinding block to automatically adjust its radial position to form an arc-shaped grinding surface that matches the outer diameter of the steel pipe. A rotating shaft 14 is installed in the slide 12 at the front end of the hollow frame 11. The rotating shaft is connected to the arc-shaped clamp 15. The operator pushes the slider 16 through the grip rod 19, causing the arc-shaped clamp to slide along the slide until the two semi-circular clamps close together and hold the steel pipe. The slider 16 cooperates with the interface 20 of the fixing block 18 to lock the position of the clamp. The connecting frame 13 is fixed inside the hollow frame. Its hole structure provides guidance for the rotating shaft 14 to prevent the steel pipe from shifting during clamping, and cooperates with the adaptive adjustment of the grinding components.

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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
