Description

TECHNICAL FIELD

[0001] The utility model relates to metal processing equipment technical field especially relates to a kind of clamping tool of galvanized pipe steel pipe processing. BACKGROUND

[0002] Hot galvanizing steel pipe is immersed into molten zinc, so that a layer of zinc is attached to the surface of the steel pipe. This galvanizing method produces a thick zinc layer with strong corrosion resistance. The zinc layer is tightly bonded to the steel pipe substrate, effectively preventing rusting and prolonging the service life of the steel pipe. It is commonly used in building water supply and drainage, fire protection piping, gas piping and other fields with high corrosion resistance requirements.

[0003] The existing galvanized pipe steel pipe processing clamping tool clamps the galvanized pipe by rotating the screw rod to move the clamping block and clamping plate. The screw rod is fixedly installed on the baffle and welded through the movable clamping block and the surface of the fixed clamping block. By rotating the handle to drive the screw rod, the movable clamping block is moved closer to or away from the fixed clamping block, achieving clamping and fixing of the galvanized pipe. However, for some non-standard circular and special-shaped galvanized pipes, such as oval and concave-convex surface steel pipes, the clamping block cannot fit the surface well, resulting in unstable clamping, causing the steel pipe to move during processing, affecting the quality of the product. The existing technology adds rubber and polyurethane inside the clamp. These materials can elastically deform under the action of clamping force, tightly fit the concave-convex surface of the galvanized pipe, ensuring clamping force and enhancing the adaptability to special-shaped surfaces. However, during frequent clamping and loosening, the elastic material may experience elastic fatigue, causing the elastic recovery ability of the elastic material to gradually decrease, resulting in poor clamping effect of the clamping block, poor fit to the surface of the galvanized pipe, and displacement and shaking of the galvanized pipe during processing, affecting the processing precision. SUMMARY

[0004] To overcome the above shortcomings, the utility model provides a kind of clamping tool of galvanized pipe steel pipe processing, to improve the problem that in the frequent clamping and loosening process of prior art, elastic material may experience elastic fatigue, causing the elastic recovery ability of the elastic material to gradually decrease, resulting in displacement and shaking of the galvanized pipe during processing, affecting the processing precision.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a clamping fixture for processing galvanized steel pipes, including an operating table 1. Fixed short plates 6 are fixedly connected to the top left and right sides of the operating table 1. A threaded column 4 is rotatably connected to the middle of the fixed short plate 6. An internal threaded ring 20 is threadedly connected to the outer wall of the threaded column 4. Rotating the threaded column 4 can move and adjust the internal threaded ring 20 on the outer wall. Rotating rods 19 are equidistantly rotatably connected to the outer circumference of the internal threaded ring 20. An arc-shaped plate 18 is rotatably connected to the other end of the outer wall of the rotating rod 19. A cross-shaped inner sliding groove plate 8 is fixedly connected to the adjacent side of the outer wall of the fixed short plate 6. The left side of the outer wall of the arc-shaped inner sliding groove plate 18 is connected to the cross-shaped inner sliding groove plate 8. The internal sliding connection of the slot plate 8 and the top of the arc plate 18 are fixedly connected with multiple spring plates 7 at equal intervals. The spring plates 7 play a shrinking and fitting role. A cleaning mechanism 2 is installed on the rear side of the outer wall of the operating table 1. The cleaning mechanism 2 is used to clean the debris and residue during processing. A hollow box 9 is fixedly connected to the front side of the outer wall of the operating table 1. A storage box 10 is slidably connected inside the hollow box 9. The storage box 10 can easily collect and store waste and residue. A handle 13 is fixedly connected to the front side of the outer wall of the storage box 10. The handle 13 can easily open and close the storage box 10. An anti-slip sleeve 12 is fixedly connected to the outer wall of the handle 13.

[0032] Specifically, by rotating the threaded column 4, since the internal threaded ring 20 is threadedly connected to the threaded column 4, the internal threaded ring 20 will move left and right on the outer wall of the threaded column 4. Because rotating rods 19 are equidistantly connected to the outer wall of the internal threaded ring 20, when the internal threaded ring 20 moves, the rotating rods 19 will rotate with the movement of the internal threaded ring 20. At the same time, because the other end of the rotating rod 19 is rotatably connected to the arc-shaped plate 18, and the left side of the outer wall of the arc-shaped plate 18 is slidably connected to the inside of the cross-shaped inner sliding groove plate 8, this restricts the movement trajectory of the arc-shaped plate 18, so that the arc-shaped plate 18 can only slide within the cross-shaped inner sliding groove plate 8, making opening and closing movements, and fitting on the arc-shaped inner sliding groove plate 8. The galvanized steel pipe outside the plate 18 is spread and fixed. When the spring plate 7 at the top of the arc plate 18 contacts the inside of the steel pipe, the spring plate 7 will elastically deform according to the shape and size of the steel pipe, so that the clamping force is more evenly distributed, improving the stability and reliability of clamping. A hollow box 9 is fixedly connected to the front side of the outer wall of the operating table 1. A storage box 10 is slidably connected inside the hollow box 9. The storage box 10 can easily collect and store waste residue. A handle 13 is fixedly connected to the front side of the outer wall of the storage box 10. The handle 13 can easily open and close the storage box 10. An anti-slip sleeve 12 is fixedly connected to the outer wall of the handle 13.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The cleaning mechanism 2 includes a motor 201, which is mounted on the rear side of the outer wall of the operating platform 1. A gear 202 is fixedly connected to the output end of the motor 201. A chain 204 is mounted on the outer wall of the gear 202. A gear 208 is rotatably connected to the left rear end of the outer wall of the operating platform 1. The gear 208 and gear 202 are connected via the chain 204. Rotation of the chain 204 enables the two gears to rotate synchronously. Threaded rods 206 are fixedly connected to the front side of the outer wall of both gear 202 and gear 208. A fan blade 207 is fixedly connected to the rear side of the outer wall of the threaded rod 206. The outer wall of the threaded rod 206 is threaded with a movable block 203. A cleaning brush 205 is fixedly connected to the top of the movable block 203. By rotating the threaded rod 206, the outer wall movable block 203 can be driven, and the cleaning brush 205 on the top can move and clean. The bottom left and right sides of the worktable 1 are fixedly connected with a base plate 14. The base plate 14 can enhance the overall stability of the worktable 1. The top of the base plate 14 is threaded with multiple screws 15. The lower left side of the outer wall of the worktable 1 is fixedly connected with a hollow box 11. The hollow box 11 is slidably connected with a drawer 16 inside. The drawer 16 can facilitate the storage of tools for daily use and maintenance.

[0034] Specifically, by turning on the motor 201, the output gear 202 is driven to rotate. Since gear 202 is connected to gear 208 via chain 204, when gear 202 rotates, it transmits power to gear 208 via chain 204, causing gear 208 and gear 202 to rotate synchronously. Since threaded rods 206 are fixedly connected to the front of the outer wall of both gear 202 and gear 208, and fan blades 207 are fixedly connected to the rear of the outer wall of threaded rods 206, the rotation of threaded rods 206 will drive the fan blades 207 to rotate. The rotation of fan blades 207 will generate airflow, which can blow some lighter debris and residue in a specific direction for easy collection and cleaning later. Finally, the rotation of threaded rods 206 will drive the cleaning brush 205 on the top of the moving block 203 to clean the debris and residue left on the surface of the worktable 1 during the processing.

[0035] Reference Figure 1 and Figure 2 A handle 21 is fixedly connected to the left side of the outer wall of the drawer 16. The handle 21 can facilitate the opening and closing of the drawer 16 for use. An anti-slip sleeve 27 is fixedly connected to the outer wall of the handle 21. A screw 3 is threadedly connected to the right side of the outer wall of the worktable 1. A hook 5 is threadedly connected to the outer wall of the screw 3. The hook 5 can facilitate the staff to hang tools for daily use and cleaning.

[0036] Specifically, a handle 21 is fixedly connected to the left side of the outer wall of the drawer 16. The handle 21 facilitates the opening and closing of the drawer 16 for use. An anti-slip sleeve 27 is fixedly connected to the outer wall of the handle 21. A screw 3 is threadedly connected to the right side of the outer wall of the worktable 1. A hook 5 is threadedly connected to the outer wall of the screw 3. The hook 5 facilitates the hanging of tools for daily use and cleaning by the staff.

[0037] Working principle: By rotating the threaded column 4, since the internal threaded ring 20 is threadedly connected to the threaded column 4, the internal threaded ring 20 will move left and right on the outer wall of the threaded column 4. Because rotating rods 19 are equidistantly connected to the outer wall of the internal threaded ring 20, when the internal threaded ring 20 moves, the rotating rods 19 will rotate with the movement of the internal threaded ring 20. At the same time, because the other end of the rotating rod 19 is rotatably connected to the arc-shaped plate 18, and the left side of the outer wall of the arc-shaped plate 18 is slidably connected to the inside of the cross-shaped inner sliding groove plate 8, this restricts the movement trajectory of the arc-shaped plate 18, thus allowing the arc-shaped plate 18 to only move left and right. It can slide within the cross-shaped inner sliding plate 8 and perform opening and closing movements. The galvanized steel pipe, which is sleeved outside the arc plate 18, is supported and fixed. Finally, when the spring plate 7 at the top of the arc plate 18 contacts the inside of the steel pipe, the spring plate 7 will elastically deform according to the shape and size of the steel pipe, making the clamping force distribution more uniform and improving the stability and reliability of clamping. This avoids the phenomenon of elastic fatigue of the elastic material during frequent clamping and loosening, which causes the elastic recovery ability of the elastic material to gradually decrease, resulting in displacement and shaking of the galvanized pipe during processing, affecting the processing accuracy.

[0038] By turning on the motor 201, the output gear 202 is driven to rotate. Since gear 202 is connected to gear 208 via chain 204, when gear 202 rotates, it transmits power to gear 208 via chain 204, causing gear 208 and gear 202 to rotate synchronously. Since threaded rods 206 are fixedly connected to the front of the outer wall of both gear 202 and gear 208, and fan blades 207 are fixedly connected to the rear of the outer wall of threaded rods 206, the rotation of threaded rods 206 will drive the fan blades 207 to rotate. The rotation of fan blades 207 will generate airflow, which can blow some lighter debris and residue in a specific direction for easy collection and cleaning later. Finally, the rotation of threaded rods 206 will drive the cleaning brush 205 on the top of the moving block 203 to sweep away the debris and residue left on the surface of the worktable 1 during the processing, thereby achieving the effect of cleaning the surface of the worktable 1.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
