Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe production and manufacturing equipment, specifically to a weld grinding device used in steel pipe production and manufacturing. Background Technology

[0002] Steel pipes are devices made of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. Due to their unique characteristics, steel pipes are widely used in many industries and fields. Steel pipes have a wide range of uses, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial installations. Therefore, after the steel pipes are produced, the weld seams on their surface need to be ground to ensure the smoothness of the steel pipes.

[0003] In the existing technology, steel pipe weld grinding equipment can only be used to fix steel pipes of a single diameter, and cannot fix steel pipes of multiple diameters. At the same time, the traditional grinding method is to manually hold the grinding machine to grind the steel pipe, which cannot be automated, wasting a lot of manpower and time and reducing work efficiency. In addition, the debris generated during the grinding process brings troublesome cleaning and collection after the grinding work is completed. Therefore, this utility model proposes a weld grinding device for steel pipe manufacturing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a weld grinding device for steel pipe manufacturing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a weld grinding device for steel pipe manufacturing, comprising: a fixed box, characterized in that: a lower screw is rotatably sleeved inside the fixed box, and a fixing mechanism is provided on both sides of the lower screw. The fixing mechanism includes an inner support block, one side of the inner support block is fixedly connected to an anti-slip block, the other side of the inner support block is rotatably connected to one end of a long connecting rod, the other end of the long connecting rod is rotatably connected to a connecting seat, the connecting seat is fixedly connected to the output end of a lower electric cylinder, the lower electric cylinder is fixedly installed inside a rotating column, the outer ring surface of the rotating column is rotatably connected to one end of a short connecting rod, and the other end of the short connecting rod is rotatably connected to the inner support block.

[0006] A drive mechanism is provided on one side of the rotating column, and a grinding mechanism is provided on the upper side of the drive mechanism.

[0008] Preferably, the rotating column is rotatably sleeved on the top of the support base, one side of the bottom of the support base is threadedly connected to the lower screw, and the other side of the bottom of the support base is slidably connected to the lower slide rod, with both ends of the lower slide rod fixedly sleeved on the fixed box.

[0009] Preferably, a synchronous motor is fixedly installed on one side of the support base, and the drive gear is fixedly sleeved on the output end of the synchronous motor, with the output end of the synchronous motor rotatably sleeved inside the support base.

[0010] Preferably, a collection box is slidably connected to the bottom of the fixed box, and a lower motor is provided on one side of the collection box. The output end of the lower motor is fixedly connected to one end of the lower screw, and the lower motor is fixedly installed on one side of the outer wall of the fixed box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By extending the output end of the lower electric cylinder, the lower electric cylinder drives the connecting seat to move. Under the rotational connection of the long connecting rod, the connecting seat drives the inner support block to move away from the lower electric cylinder. At the same time, under the rotational connection of the short connecting rod and the rotating column, the anti-slip block abuts against the inner ring surface of the steel pipe end, thereby fixing the steel pipe.

[0015] 2. By adjusting the position of the grinding mechanism, the grinding wheel is brought into contact with the weld seam on the outer wall of the steel pipe. Finally, the steel pipe is rotated by the drive mechanism, and the grinding wheel is started at the same time, so that the weld seam on the steel pipe is ground. This can automatically grind the steel pipe, saving a lot of manpower and time, improving work efficiency, and bringing positive effects to the grinding work. In addition, impurities during the grinding process fall into the fixed box, thus avoiding the trouble of subsequent collection and cleaning. Attached Figure Description

[0024] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0025] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a weld grinding device for steel pipe production, comprising: a fixed box 1, a lower screw 2 rotatably mounted inside the fixed box 1, fixing mechanisms 3 on both sides of the lower screw 2, the fixing mechanism 3 including an inner support block 4, one side of the inner support block 4 being fixedly connected to an anti-slip block 5, the other side of the inner support block 4 being rotatably connected to one end of a long connecting rod 6 via a pin, the other end of the long connecting rod 6 being rotatably connected to a connecting seat 7 via a pin, the connecting seat 7 being fixedly connected to the output end of a lower electric cylinder 8, the lower electric cylinder 8 being fixedly installed inside a rotating column 9, the outer ring surface of the rotating column 9 being rotatably connected to one end of a short connecting rod 10 via a pin, the other end of the short connecting rod 10 being rotatably connected to the inner support block 4 via a pin, a driving mechanism 11 being provided on one side of the rotating column 9, and a grinding mechanism 12 being provided on the upper side of the driving mechanism 11.

[0026] In use, the lower screw 2 has two threads with opposite directions. The fixing box 1 provides fixed support for the entire device. The steel pipe that needs to be welded and ground is placed in the fixing box 1, and the lower screw 2 is rotated according to the length of the steel pipe to adjust the distance between the fixing mechanisms 3 on both sides, thus facilitating the fixing of steel pipes of different lengths. The end of the steel pipe is sleeved on the outside of the anti-slip block 5. Through the extension of the output end of the lower electric cylinder 8, the lower electric cylinder 8 drives the connecting seat 7 to move. Under the rotational connection of the long connecting rod 6, the connecting seat 7 drives the inner support block 4 to move away from the lower electric cylinder 8. At the same time, under the rotational connection of the short connecting rod 10 and the rotating column 9, The anti-slip block 5 abuts against the inner ring surface of the steel pipe end, thereby fixing the steel pipe. Then, by adjusting the position of the grinding mechanism 12, the grinding wheel abuts against the weld seam on the outer wall of the steel pipe. Finally, the driving mechanism 11 drives the steel pipe to rotate, and at the same time starts the grinding wheel, thereby grinding the weld seam on the steel pipe. Furthermore, by controlling the extension and retraction length of the output end of the lower electric cylinder 8, steel pipes of various diameters can be fixed, and the steel pipe can be automatically ground, saving a lot of manpower and time, improving work efficiency, and bringing positive effects to the grinding work. In addition, impurities during the grinding process fall into the fixed box 1, thus avoiding the trouble of subsequent collection and cleaning.

[0027] Example 2: Based on Example 1, the drive mechanism 11 includes a driven gear 13, which is fixedly sleeved on one end of the rotating column 9. The bottom of the driven gear 13 meshes with the driving gear 14 for transmission. Through the meshing transmission between the driving gear 14 and the driven gear 13, the driven gear 13 drives the rotating column 9 to rotate. The rotating column 9 is rotatably sleeved on the top of the support base 15. One side of the bottom of the support base 15 is threadedly connected to the lower screw 2, and the other side of the bottom of the support base 15 is slidably connected to the lower sliding rod 16. Both ends of the lower sliding rod 16 are fixedly sleeved on the fixed box 1. A synchronous motor 26 is fixedly installed on one side, and a drive gear 14 is fixedly sleeved on the output end of the synchronous motor 26. The output end of the synchronous motor 26 is rotatably sleeved in the support base 15. There are two support bases 15, which are symmetrically arranged about the central plane of the fixed box 1. A collection box 17 is slidably connected to the bottom of the fixed box 1. A lower motor 18 is provided on one side of the collection box 17. The output end of the lower motor 18 is fixedly connected to one end of the lower screw 2. The lower motor 18 is fixedly installed on one side of the outer wall of the fixed box 1. The collection box 17 is slidably installed on the bottom of the fixed box 1, which facilitates the removal and placement of the collection box 17.

[0028] By starting the lower motor 18, the lower motor 18 drives the lower screw 2 to rotate. The lower screw 2 has two threads with opposite directions of rotation, thereby driving the support base 15 to move under the action of the rotation of the lower screw 2. The two support bases 15 can move towards each other or away from each other under the limitation of the sliding rod 16, so as to facilitate the adjustment of the distance between the two support bases 15, and thus facilitate the fixing of steel pipes of different lengths. After the steel pipe is fixed by the fixing mechanism 3, the synchronous motor 26 is started, and the synchronous motor 26 drives its output end to fix the connection. The drive gear 14 rotates, and the drive gear 14 meshes with the driven gear 13 for transmission. The driven gear 13 is fixedly sleeved on one end of the rotating column 9, thereby driving the rotating column 9 to rotate under the limit of the support seat 15, and then driving the steel pipe fixed on the fixed mechanism 3 to rotate, so that it can rub against the grinding wheel more quickly, remove the weld seam more quickly, and increase the surface smoothness of the steel pipe. During the grinding process, the generated debris falls into the collection box 17 at the bottom of the fixed box 1, thereby avoiding the trouble of cleaning and collecting impurities and debris later.

[0029] Example 3: Based on Example 2, a fixed frame 19 is provided on the upper side of the lower motor 18. The bottom two sides of the fixed frame 19 are fixedly connected to the fixed box 1. An upper screw 20 is rotatably sleeved on one side of the top of the fixed frame 19, and an upper slide rod 21 is fixedly sleeved on the other side of the top of the fixed frame 19. One end of the upper screw 20 is fixedly connected to the output end of the upper motor 22. The fixed frame 19 provides fixed support for the grinding mechanism 12. The top of the fixed frame 19 provides limiting support for the upper screw 20 and the upper slide rod 21. The upper motor 22 is fixedly installed on one side of the top of the fixed frame 19. The grinding mechanism 12 includes a grinding machine 23. The upper side of the grinding machine 23 is fixedly connected to the output end of the upper electric cylinder 24. The non-output end of the upper electric cylinder 24 is fixedly connected to the moving block 25. One side of the moving block 25 is threadedly sleeved with the upper screw 20, and the other side of the moving block 25 is slidably connected to the upper slide rod 21.

[0030] Before grinding the weld seam, the upper motor 22 is controlled to drive the upper screw 20 to rotate, thereby driving the moving block 25 to move. The moving block 25 can move laterally under the limit of the upper slide rod 21, thereby driving the grinding mechanism 12 to move. This makes it easier for the grinding mechanism 12 to grind the weld seam at different positions on the steel pipe. After adjusting to the appropriate position, the extension and retraction of the upper electric cylinder 24 is controlled to facilitate the welding contact between the grinding wheel and the outer ring of the steel pipe. This makes it easier to adapt to steel pipes of different diameters and improves the practicality of the entire device.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
