[0002] The spiral steel pipe is made of steel coils, extruded at room temperature, and welded by automatic double-wire double-sided submerged arc welding. The welding parts of the spiral steel pipe are relatively rough during the production process, so a polishing device is needed to grind the welding parts and the surface of the spiral steel pipe in the later stage. The spiral steel pipe needs to be rotated during the grinding process so that the grinding equipment can grind the spiral steel pipe more evenly.

Therefore, a polishing device for spiral steel pipe processing that is easy to adjust the rotation direction is proposed, and the rotation angle of the spiral steel pipe is controlled by a positioning clamp to solve the above problems.

DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1~Figure 3 As shown, a polishing device for spiral steel pipe processing that is easy to adjust the rotation direction includes a bracket assembly 1, which is composed of a landing frame 101, a positioning ring 102 and a support rod 103. The positioning ring 102 is provided with a rotating assembly 2 inside. The rotating assembly 2 includes a positioning clamping ring 201 fixedly connected to the inside of the positioning ring 102, a clamping ring 202 is rotatably connected to the inside of the positioning ring 102, and a cavity base 203 is fixedly connected to the outer end of the clamping ring 202. A slide 204 is slidably connected to the inside of the cavity base 203, and a roller 205 is rotatably connected to the inside of the slide 204. The purpose of this arrangement is that the slide 204 is stuck in the inside of the positioning clamping ring 201, and the slide 204 can slide in the inside of the cavity base 203, and the rotation direction of the inside of the clamping ring 202 can be controlled automatically.

[0024] Preferably, the inner wall of the positioning clamp ring 201 is provided with protrusions, and the protrusions are provided with thirty groups and arranged in a circular shape with equal distances, and the space between two adjacent groups of protrusions is in an arc shape. The purpose of this arrangement is that the thirty groups of protrusions set up enable the clamping ring 202 to drive the spiral steel pipe to rotate 12 degrees each time, and the rotation angle of the spiral steel pipe is fixed each time, thereby improving the uniformity of the grinding of the spiral steel pipe.

[0025] Preferably, the cavity base 203 is provided with thirty groups, and grooves are symmetrically opened on both sides of the cavity base 203. Slide blocks are symmetrically fixedly connected to both sides of the bottom end of the slide seat 204. The rotating assembly 2 also includes a clamping rod 206 fixedly connected to the inside of the groove, and a spring 207 is sleeved on the outer end of the clamping rod 206. The spring 207 is fixedly connected between the bottom side of the groove and the slide block. The purpose of this arrangement is that the spring 207 allows the slide seat 204 to be quickly clamped between two groups of adjacent protrusions, thereby fixing the rotation position of the clamping ring 202.

[0026] In this embodiment, after the spiral steel pipe is fixed to the positioning ring 102 between the two groups of landing frames 101, the equipment grinds both sides of the spiral steel pipe and then rotates the spiral steel pipe. At this time, the roller 205 inside the slide 204 rotates inside the positioning clamping ring 201. The two groups of adjacent protrusions are arranged in an arc shape, so that the roller 205 slides more smoothly. After the clamping ring 202 rotates 12 degrees, the spring 207 drives the slide 204 inside the cavity base 203 to reset, so that it is stuck between the two groups of adjacent protrusions, and then the spiral steel pipe inside the clamping ring 202 is limited, so that the grinding of the outer side of the spiral steel pipe is more uniform.

[0027] Example 2

[0028] like Figure 1~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the internal thread of the clamping ring 202 is connected with a bolt 3, one end of the bolt 3 is rotatably connected with a gasket 4, and the bottom of the gasket 4 is toothed. The purpose of this arrangement is that after the spiral steel pipe is clamped into the positioning ring 102 inside the two sets of landing frames 101, the bolt 3 is rotated so that the gasket 4 of the bottom rotating cover clamps and positions the spiral steel pipe, making the spiral steel pipe more stable during grinding.

[0029] Preferably, two groups of floor stands 101 are provided, and the support rod 103 is fixedly connected between the two groups of floor stands 101. A fixing rod 5 is fixedly connected between the two groups of floor stands 101. The outer end of the fixing rod 5 is fixedly connected to a chassis 6. A cylindrical groove is provided inside the chassis 6. A grinding roller 7 is rotatably connected inside the cylindrical groove. A servo motor 8 is fixedly connected to the outer end of the chassis 6. The output end of the servo motor 8 is fixedly connected to the grinding roller 7. The purpose of this arrangement is that one side of the chassis 6 is arc-shaped, and the debris generated by the grinding of the spiral steel pipe can be shielded during the grinding process to prevent the debris from splashing and being difficult to clean. At the same time, two groups of grinding rollers 7 are used to grind the spiral steel pipe at the same time, thereby improving the grinding efficiency of the spiral steel pipe.

[0030] Preferably, two groups of chassis 6 are provided, the tops of the two groups of chassis 6 are fixedly connected with cavity drain plates 9, the inside of the cavity drain plates 9 is fixedly connected with nozzles 10, the bottoms of the two groups of chassis 6 are fixedly connected with cavity recovery plates 11, and the inside of the cavity recovery plates 11 is fixedly connected with filter screens 12. The purpose of this arrangement is that the temperature of the spiral steel pipe is relatively high during the grinding process, and sparks will be generated during the grinding. The water sprayed by the nozzles 10 inside the cavity drain plates 9 can cool the spiral steel pipe while preventing sparks from flying.

[0031] In this embodiment, during the grinding process of the spiral steel pipe, the water pipe is connected to the outside of the cavity drainage plate 9. At this time, water is sprayed on the surface of the spiral steel pipe through the nozzle 10, thereby cooling the spiral steel pipe and preventing sparks from being generated during the grinding process. The outflowing water then flows into the cavity recovery plate 11, and the filter screen 12 arranged inside it filters the water. The filtered water can be recycled to reduce the waste of water resources.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
