[0002] In the field of pipeline engineering, steel pipes, as hollow long and round steel materials, are widely used as various conveying pipelines due to their good strength and fluid transport performance. In the steel pipe processing and production process, grinding is a key process to improve surface quality, enhance corrosion resistance and beautify appearance, and the use of steel pipe grinding equipment is indispensable. However, most current steel pipe grinding devices have significant drawbacks in their clamping and fixing components. They mostly use a clamping and fixing method on the outer surfaces of both ends of the steel pipe, making it difficult to grind the clamped areas, thus affecting the overall processing quality. Furthermore, during the grinding process, the clamping components can easily cause wear and scratches to the outer surface of the steel pipe, and it is difficult to quickly and flexibly adjust the clamping distance according to different pipe lengths, resulting in poor applicability and significant limitations. Therefore, we provide a steel pipe grinding device for pipeline engineering to solve these problems. Utility Model Content

This grinding device changes the traditional clamping method, eliminates the wear caused to the outer surface of the steel pipe during the clamping process, and can achieve complete grinding of the entire surface. Moreover, the distance between the two fixing components can be quickly and flexibly adjusted according to the length of the steel pipe.

A connecting rod is slidably connected inside the two sliding grooves. A column is fixedly connected to the upper surface of the worktable, and a rotating shaft is rotatably connected to the inner wall of the connecting rod and the column. A fixing component is installed at the end of the two rotating shafts that are close to each other. A servo motor is installed on the left side of the column, and the output end of the servo motor is connected to the rotating shaft located on the left side.

A connecting block is threaded onto the outer surface of each stud. Four limiting grooves are provided on the outer surface of the mounting shell, and the four connecting blocks are located inside the four limiting grooves. A positioning post is fixedly connected to the end of each connecting block that is away from the four studs.

[0006] Preferably, in the above-mentioned steel pipe grinding device for pipeline engineering, one end of the stud extends to the outside of the mounting shell and is fixedly connected to a turntable, the inner wall of the turntable is threadedly connected to a stud two, and a limit block is fixedly connected to one end of the stud two near the mounting shell.

[0007] Preferably, in the above-mentioned steel pipe grinding device for pipeline engineering, a movable component is installed on the inner top wall of the vertical plate.

[0010] The advantages and beneficial effects of this utility model are: This utility model utilizes the cooperation between the sliding groove, connecting rod, and fixing components. When using this steel pipe grinding device, pushing the connecting rod and cooperating with the sliding groove allows for quick and flexible adjustment of the distance between the two fixing components according to the length of the steel pipe. Rotating the turntable drives the connected studs and bevel gears to rotate. Through the meshing of the four bevel gears, the four studs can rotate synchronously.

An external control switch activates an electric push rod, causing the grinding stone to move downwards and adhere to the surface of the steel pipe. With the cooperation of a telescopic rod and a spring, the grinding stone remains in close contact with the steel pipe surface. As the moving component moves the grinding component, the servo motor is simultaneously activated. The rotating shaft causes the fixed component and the steel pipe to rotate at a uniform speed, allowing the grinding stone to perform comprehensive and efficient grinding of the steel pipe, effectively improving grinding efficiency. By rotating the limiting plate, with the cooperation of studs, the limiting plate can be tightly fitted to the surface of the vertical plate, thereby fixing the adjusted connecting rod and improving stability during the grinding process.

A column 5 is fixedly connected to the upper surface of the workbench 1, and a rotating shaft 6 is rotatably connected to the inner wall of both the connecting rod 4 and the column 5. Fixing components 7 are installed at the ends of the two rotating shafts 6 that are close to each other. A servo motor 8 is installed on the left side of the column 5, and the output end of the servo motor 8 is connected to the rotating shaft 6 located on the left side. The workbench 1 serves as the supporting foundation for the entire device and provides an installation platform for other components. The upright plate 2 is vertically fixed to the upper surface of the workbench 1, and the side of the upright plate 2 and the sliding groove 3 opened on the upper surface of the workbench 1 are adapted to the connecting rod 4. The connecting rod 4 can slide along the length of the sliding groove 3. The column 5 is located on the left side of the connecting rod 4 and together with the connecting rod 4, it provides a support point for the rotating shaft 6. The steel pipe can be fixed by two fixing components 7. By starting the servo motor 8, the fixing components 7 and the fixed steel pipe can be driven to rotate at a uniform speed under the action of the rotating shaft 6.

[0016] The fixing component 7 includes a mounting shell 701, which is fixedly connected to the rotating shaft 6. The inner wall of the mounting shell 701 is rotatably connected to four studs 702, which are arranged in a cross shape. The ends of the four studs 702 that are close to each other are fixedly connected to bevel gears 703, which mesh with each other. The outer surfaces of the four studs 702 are threaded with connecting blocks 704. The outer surface of the mounting shell 701 is provided with four limiting grooves 705. The four connecting blocks 704 are located inside the four limiting grooves 705. The ends of the four connecting blocks 704 that are away from the four studs 702 are fixedly connected to positioning pins 706.

[0017] The mounting shells 701 of the two fixed components 7 are respectively connected to the two rotating shafts 6. The mounting shells 701 can rotate synchronously with the rotating shafts 6. The inner wall of the mounting shells 701 is machined with mounting holes for mounting studs 702. The four bevel gears 703 mesh with each other in sequence to form a transmission structure. The connecting block 704 is machined with internal threaded holes that match studs 702. The limiting groove 705 limits the connecting block 704. Its width is adapted to the connecting block 704 so that it can only move along the axis of studs 702. The positioning pin 706 is used to insert into the inner wall of the steel pipe to support and fix the steel pipe.

[0018] One end of stud 702 extends to the outside of the mounting housing 701 and is fixedly connected to a turntable 707. The inner wall of the turntable 707 is threadedly connected to stud 708. The end of stud 708 near the mounting housing 701 is fixedly connected to a limit block 709.

[0019] One end of stud 702 extends through the through hole of the mounting housing 701 to the outside and is connected to the turntable 707. The turntable 707 is a circular plate structure, which is convenient for the operator to rotate manually. The inner wall of the turntable 707 is machined with an internal threaded hole. Stud 708 is threaded to the inner wall of the turntable 707 through the threaded hole. The limiting block 709 is a circular block structure. When the turntable 707 is rotated to adjust the position of the positioning post 706, the stud 708 is rotated so that the limiting block 709 can be tightly attached to the outer surface of the mounting housing 701, restricting the rotation of stud 702, thereby fixing the position of the positioning post 706.

[0020] A movable component 9 is installed on the inner top wall of the upright plate 2. The movable component 9 includes a mounting frame 901, which is fixedly connected to the inner top wall of the upright plate 2. A lead screw 902 is rotatably connected to the inner wall of the mounting frame 901. The right end of the lead screw 902 extends to the right side of the mounting frame 901. A forward and reverse motor 903 is fixedly connected to the right side of the mounting frame 901. The right end of the lead screw 902 is connected to the output end of the forward and reverse motor 903. A connecting block 904 is threadedly connected to the outer surface of the lead screw 902. A limiting slide rod 905 is fixedly connected to the inner wall of the mounting frame 901. The connecting block 904 is slidably connected to the outer surface of the limiting slide rod 905.

[0021] The forward and reverse motor 903 can provide a power source, which makes the lead screw 902 rotate within the mounting frame 901. The inner wall of the connecting block 904 is machined with an internal thread hole that matches the lead screw 902. It is threadedly connected to the outer surface of the lead screw 902 through the thread hole. The limiting slide rod 905 limits the connecting block 904, so that it can only move along the axial direction of the lead screw 902.

[0022] A grinding component 10 is installed on the bottom surface of the connecting block 2 904. The grinding component 10 includes an electric push rod 1001. The electric push rod 1001 is installed on the bottom surface of the connecting block 2 904. A connecting plate 1002 is fixedly connected to the output end of the electric push rod 1001. Two telescopic rods 1004 are fixedly connected to the bottom surface of the connecting plate 1002. A grinding stone 1003 is installed at the lower end of the two telescopic rods 1004. A spring 1005 is sleeved on the outer surface of each of the two telescopic rods 1004.

[0023] The electric push rod 1001 can move with the movement of the connecting block 2 904. The steel pipe surface is polished by the polishing stone 1003. During the polishing process, the telescopic rod 1004 and the spring 1005 can provide elastic force to keep the polishing stone 1003 in contact with the steel pipe surface.

[0024] A through groove 11 is provided on the back of the upright plate 2. A stud 12 is provided inside the through groove 11. The stud 12 is connected to the connecting rod 4. A limit plate 13 is threadedly connected to the outer surface of the stud 12.

[0025] The through groove 11 is connected to the sliding groove 3 opened on the side of the upright plate 2. By rotating the limiting plate 13, with the cooperation of the stud 3 12, the limiting plate 13 can be tightly attached to the surface of the upright plate 2, thereby fixing the connecting rod 4 after adjustment.

[0026] Working Principle: When in use, the device is electrically connected to an external power supply and external control switch. The left end of the steel pipe is fitted onto the outer surface of the four positioning posts 706 of the left-side fixed assembly 7. Then, based on the length of the steel pipe, the connecting rod 4 is pushed through the sliding grooves 3 on the surfaces of the vertical plate 2 and the worktable 1, causing the connecting rod 4 to drive the fixed assembly 7 to slide along the sliding grooves 3. This adjusts the distance between the two fixed assemblies 7 to accommodate steel pipes of different lengths. After adjustment, the limiting plate 13 is rotated, and the action of the studs 12 causes the limiting plate 13 to press tightly against the vertical plate 2, fixing the connecting rod 4 and preventing it from moving during grinding. Next, the turntable 707 is rotated, driving the connected studs 702 and bevel gears 703 to rotate. Because the four bevel gears 703 mesh with each other, the four studs 702 rotate synchronously. Guided by the four limiting grooves 705, the four connecting blocks 704... The four studs 702 extend outward along their axial direction and are supported on the inner wall of the steel pipe. Then, the stud 708 is rotated so that the limiting block 709 fits tightly against the mounting shell 701, thus limiting the stud 702. After the steel pipe is fixed, the electric push rod 1001 is activated by the external control switch, causing the grinding stone 1003 to move down and fit against the surface of the steel pipe. Through the synergistic action of the telescopic rod 1004 and the spring 1005, the grinding stone 1003 is kept in close contact with the surface of the steel pipe. Then, the forward and reverse motor 903 is activated, which drives the lead screw 902 to rotate. Under the guidance of the limiting slide rod 905, the connecting block 904 moves along the axial direction of the lead screw 902, thereby driving the grinding assembly 10 to move and grind the steel pipe. At the same time, the servo motor 8 is activated, which drives the fixing assembly 7 and the steel pipe to rotate at a constant speed through the rotating shaft 6, so that the grinding stone 1003 can perform comprehensive and efficient grinding on the surface of the steel pipe.
