Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, and more specifically, it relates to a seamless steel pipe inner wall cleaning device. Background Art

[0002] Seamless steel pipes are made by piercing a whole round steel, and the steel pipes without welds on the surface are called seamless steel pipes. During the production process of seamless steel pipes, lubricants or lubricating oils are generally required to assist in piercing. After processing, there will be dirt or oil residue on the inner wall of the seamless steel pipes, so it is necessary to clean the inner walls of these seamless steel pipes.

[0003] At present, a Chinese patent with the publication (announcement) number CN210730415U discloses a steel pipe inner wall processing device, which includes an operating table. Two first support columns are welded to the top of the operating table. A first fixing rod and a second fixing rod are respectively welded to the corresponding surfaces of the two first support columns. In this steel pipe inner wall processing device, while the cleaning brush rotates, the hydraulic cylinder can drive the steel pipe to move, so that the cleaning brush can perform rust removal operations on the inner wall of the steel pipe. However, the specific operation of fixing the steel pipe in this device is as follows: turn the bolt 23, so that the clamping block 13 can be separated from the third support column 14. Insert the steel pipe to be cleaned on the inner wall into the semi-circular grooves formed by the clamping block 13 and the third support column 14, and turn the bolt 23 again, so that the steel pipe can be fixed between the third support column 14 and the clamping block 13. This fixing method requires repeatedly tightening and loosening multiple bolts 23 for each processed steel pipe, and the operation process is relatively cumbersome. Moreover, since the clamping interval formed by the third support column 14 and the clamping block 13 is fixed, it can only adapt to the processing and fixing of steel pipes of a single size, resulting in poor flexibility in the use of the device.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 As shown, a seamless steel pipe inner wall cleaning device according to an embodiment of the present utility model includes a workbench 1, on which an accommodating concave position 10 is formed. An electric slide rail 11 is arranged in the accommodating concave position 10. A fixing base 2 is arranged at the upper end of the electric slide rail 11. A supporting bottom plate 3 is arranged on the fixing base 2. Two positioning seats 30 are correspondingly arranged on the left and right of the top surface of the supporting bottom plate 3. Above the positioning seats 30, two splints 31 for positioning the steel pipe are correspondingly arranged. A cleaning mechanism for cleaning the inner wall of the steel pipe is arranged at the left end of the workbench 1.

[0021] During use, the steel pipe to be cleaned is placed above the two positioning seats 30, and the splints 31 above the positioning seats 30 are controlled to clamp and limit the steel pipe. The two positioning seats 30 respectively clamp and limit the two ends of the steel pipe to ensure the stability of the limit. The two splints 31 can adaptively clamp steel pipes with different outer diameters, improving the practicability and flexibility of the device;

[0022] After the steel pipe is clamped, start the electric slide rail 11 to drive the fixed seat 2 to move horizontally. The fixed seat 2 drives the positioning seat 30 and the steel pipe to move horizontally and contact the cleaning mechanism, so that the inner wall of the steel pipe can be contacted and cleaned by the cleaning mechanism.

[0023] A limiting chute 34 with an inverted "T" cross-sectional structure is formed in the middle of the positioning seat 30. The clamping plate 31 includes a vertical portion 32 and a bent portion 33. A slider 35 adapted to the limiting chute 34 is connected to the lower end of the vertical portion 32; sleeves 36 are provided on the vertical portions 32 of the two clamping plates 31. An adjusting rod 37 is commonly inserted into the two sleeves 36, and a first knob 38 is connected to one end of the adjusting rod 37. The cooperating portion of the adjusting rod 37 and the two sleeves 36 has two thread segments 39 with opposite helix directions.

[0024] During use, when it is necessary to clamp the steel pipe, rotate the first knob 38 forward to drive the adjusting rod 37 to rotate. The adjusting rod 37 rotates and drives the two clamping plates 31 to slide towards each other along the positioning seat 30 through the threaded connection and cooperation between the two thread segments 39 and the sleeves 36 on the two clamping plates 31 respectively, and the cooperation between the slider 35 and the limiting chute 34, and clamp and limit the steel pipe through the bent portion 33. When it is necessary to cancel the clamping of the steel pipe, rotate the first knob 38 in the reverse direction.

[0025] Two guiding slide rods 20 are correspondingly arranged on the left and right of the top surface of the fixed seat 2. The upper ends of the guiding slide rods 20 have limiting portions 21, and a guiding plate 22 is slidably arranged on the outer circle. A spring member 23 is sleeved on the outer circle of the guiding slide rod 20 between the upper end of the guiding plate 22 and the limiting portion 21. A positioning base 24 is fixedly arranged at the lower end of the supporting bottom plate 3, and the two guiding plates 22 are both fixedly connected to the positioning base 24; a cavity 46 is formed in the fixed seat 2, and a movable through opening 4 is formed on the top surface of the cavity 46. The lower end of the positioning base 24 extends into the movable through opening 4 and is provided with a first inclined waist 40. A top block 41 is slidably arranged in the cavity 46, and a second inclined waist 42 adapted to the first inclined waist 40 is formed on the top block 41; an adjusting screw rod 43 is rotatably arranged in the cavity 46, and a threaded hole 44 adapted to the adjusting screw rod 43 is formed in the middle of the top block 41. One end of the adjusting screw rod 43 penetrates and extends to one side of the fixed seat 2 and is connected to a second knob 45.

[0026] During use, the height of the positioning base 24 is adjustable, so that the height of the supporting bottom plate 3 is adjustable, so that the supporting bottom plate 3 can adjust the use height according to steel pipes of different sizes to ensure that the steel pipe and the cleaning mechanism are at the best matching height.

[0027] When it is necessary to adjust the height of the positioning base 24, rotate the second knob 45 to drive the adjusting screw rod 43 to rotate. The rotation of the adjusting screw rod 43 is in threaded connection and cooperation with the threaded hole 44, and the sliding block 41 is in sliding fit with the movable through hole 4 (the size of the sliding block 41 is adapted to the movable through hole), driving the sliding block 41 to slide leftward along the radial direction of the movable through hole. The movable sliding block 41 drives the positioning base 24 to lift through the cooperation between the second inclined waist 42 and the first inclined waist 40. The movement path of the positioning base 24 is limited through the cooperation between the guide plate 22 and the guide slide rod 20 so that it can drive the positioning base 24 to lift stably, completing the height adjustment of the base;

[0028] When it is necessary to lower the height of the positioning base 24, rotate the second knob 45 to drive the sliding block 41 to move rightward along the radial direction of the movable through hole. Since the guide plate 22 causes the spring member 23 to store energy when the positioning base 24 is lifted, the stored energy of the spring member 23 is released while the sliding block 41 moves rightward, thereby driving the positioning base 24 to reset downward to reduce its use height.

[0029] The cleaning mechanism includes a first support seat 5 and a second support seat 50 arranged above the workbench 1. A water delivery pipe 51 is rotatably arranged on the first support seat 5, and a connecting pipe 52 is rotatably arranged on the second support seat 50. The connecting pipe 52 is movably connected to the water delivery pipe 51. The end of the water delivery pipe 51 is respectively connected with a water outlet sleeve 53 and a brush sleeve 54, and the water delivery pipe 51 is also connected to a power source for controlling its rotation.

[0030] During use, the water delivery pipe 51 is supported by the first support seat, and the connecting pipe 52 is supported by the second support seat 50. The water delivery pipe 51 sends external water into the water delivery pipe 51, and then the water sprays out from the water outlet sleeve 53 to wash the inner wall of the steel pipe. During operation, the power source drives the water delivery pipe 51 to rotate, thereby driving the brush sleeve 54 to clean the inner wall of the steel pipe;

[0031] Refer to the attached Figure 1 In the specification, the power source is preferably a servo motor. The output shaft of the servo motor is connected with a first sprocket. A second sprocket is arranged on the outer wall of the water delivery pipe 51 corresponding to the first sprocket. A transmission chain is wound around the first sprocket and the second sprocket. During operation, the servo motor drives the first sprocket to rotate, and the first sprocket drives the second sprocket to rotate through the transmission chain, thereby driving the water delivery pipe 51 to rotate. The rotation of the water delivery pipe 51 drives the water outlet sleeve 53 and the brush sleeve 54 to rotate to ensure sufficient brushing and washing of the inner wall of the steel pipe.

[0032] The electrical components appearing in this article are all electrically connected to an external main controller and 220V mains power, and the main controller can be a conventional known device such as a computer for control.

[0033] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., refer to the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing this utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of this utility model.

[0034] The above are only the preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the concept of this utility model belong to the protection scope of this utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of this utility model, several improvements and refinements should also be regarded as within the protection scope of this utility model.
