Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe joint spraying, specifically a stainless steel pipe joint spraying device. Background Technology

[0002] Stainless steel pipe joint spraying is a key surface treatment technology. It is not because stainless steel "rusts", but to give it super corrosion resistance in harsh environments such as marine, chemical and underground environments, while also achieving multiple functions such as color marking, electrical insulation and mechanical protection. It is a mature industrial practice that improves product reliability, safety and service life through technical means.

[0003] In traditional stainless steel pipe joint spraying, the joint is usually threaded through a simple wire mesh, which is then hung on the spraying device and sprayed with a spray gun. However, during the spraying process, the output of the spray gun will exert a pushing force on the joint, causing the joint on the wire mesh to shake and move closer to or further away from the spray gun, thus affecting the uniformity of the spraying. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, in the traditional stainless steel pipe joint spraying process, the joint is usually threaded through a simple wire mesh, and then the wire mesh is hung on the spraying device for spraying with a spray gun. However, during the spraying process, the output of the spray gun will generate a thrust on the joint, causing the joint on the wire mesh to shake and move away from the spray gun, thus affecting the uniformity of the spraying. This utility model proposes a stainless steel pipe joint spraying device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a stainless steel pipe joint spraying device, including a workbench, a protective cover fixedly connected to the top of the workbench, a control console and a paint bucket fixedly connected to the surface of the protective cover, a paint pump fixedly connected to the bottom of the paint bucket, an output pipe fixedly connected to the output end of the paint pump, one end of the output pipe penetrating into the inner cavity of the protective cover, a clamping mechanism and a moving mechanism fixedly connected to the surface of the workbench, and an arc-shaped spray gun provided on the top of the workbench; The clamping mechanism includes a mounting block, a cylinder is fixedly connected to the inner cavity of the mounting block, the output end of the cylinder passes through the mounting block and is fixedly connected to a moving block, clamping blocks are provided on the surface of the mounting block, and there are three clamping blocks. Connecting blocks are fixedly connected to the surfaces of the mounting block and the clamping blocks. Rotating shafts are rotatably connected to the inner cavities of the moving block and the connecting blocks, and a connecting rod is movably connected to the surfaces of every two rotating shafts.

[0006] Preferably, each of the rotating shafts is fixedly fitted with two limiting rings on its surface, and the surface of the limiting rings is movably connected to the surface of the connecting rod.

[0007] Preferably, each of the clamping blocks has an anti-slip pad fixedly connected to its surface, and the anti-slip pad is made of rubber.

[0008] Preferably, a first motor is fixedly connected to the bottom of the workbench, and the output end of the first motor passes through the workbench and is fixedly connected to the bottom of the mounting block.

[0009] Preferably, the moving mechanism includes a mounting frame, the bottom of which is fixedly connected to the top of the workbench, and a second motor is fixedly connected to the top of the mounting frame. The output end of the second motor passes through the mounting frame and is fixedly connected to a threaded rod. A sliding block is threadedly connected to the surface of the threaded rod, and the surface of the sliding block is fixedly connected to the surface of the arc-shaped spray gun.

[0010] Preferably, one end of the output pipe is fixedly connected to a flexible tube, and one end of the flexible tube is fixedly connected to the inner cavity of the arc-shaped spray gun.

[0011] Preferably, the inner cavity of the mounting bracket is provided with a movable groove, and the inner cavity of the movable groove is movably connected to the surface of the sliding block.

[0012] The advantages of this utility model are: This invention utilizes a workbench, protective cover, paint bucket, paint pump, output pipe, clamping mechanism, moving mechanism, control console, and arc-shaped spray gun in conjunction. The clamping mechanism holds stainless steel pipe joints of different inner diameters from the inside while rotating them during the spraying process. The moving mechanism can move the arc-shaped spray gun up and down, adapting to spraying joints with excessive height. This solves the problem in traditional stainless steel pipe joint spraying, where the joint is typically placed on a simple wire mesh, which is then hung on the spraying device for spraying. However, during the spraying process, the output of the spray gun exerts a pushing force on the joint, causing the joint on the wire mesh to sway and move back and forth from the spray gun, thus affecting the uniformity of the spraying.

[0016] 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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses a stainless steel pipe joint spraying device. (Refer to...) Figure 1 and Figure 4 A stainless steel pipe joint spraying device includes a workbench 1, a protective cover 2 fixedly connected to the top of the workbench 1, a control console 8 and a paint bucket 3 fixedly connected to the surface of the protective cover 2, a paint pump 4 fixedly connected to the bottom of the paint bucket 3, an output pipe 5 fixedly connected to the output end of the paint pump 4, one end of the output pipe 5 penetrating into the inner cavity of the protective cover 2, a clamping mechanism 6 and a moving mechanism 7 fixedly connected to the surface of the workbench 1, and an arc-shaped spray gun 9 provided on the top of the workbench 1. The clamping mechanism 6 includes a mounting block 601, a cylinder 603 is fixedly connected to the inner cavity of the mounting block 601, the output end of the cylinder 603 passes through the mounting block 601 and is fixedly connected to a moving block 604, clamping blocks 608 are provided on the surface of the mounting block 601, and there are three clamping blocks 608. Connecting blocks 606 are fixedly connected to the surfaces of the mounting block 601 and the clamping blocks 608. Rotating shafts 607 are rotatably connected to the inner cavities of the moving block 604 and the connecting blocks 606. Connecting rods 605 are movably connected to the surfaces of every two rotating shafts 607.

[0018] Reference Figure 3 and Figure 4Two limiting rings 610 are fixedly sleeved on the surface of each rotating shaft 607. The surface of the limiting ring 610 is movably connected to the surface of the connecting rod 605. The position of the connecting rod 605 is limited by the limiting rings 610, thereby improving the stability of the connecting rod 605 during rotation. Reference Figure 3 Each clamping block 608 has an anti-slip pad 609 fixedly connected to its surface. The anti-slip pad 609 is made of rubber. By setting the clamping block 608, the friction between the surface of the clamping block 608 and the inner diameter of the stainless steel pipe joint is increased, thereby improving the internal support and clamping effect. Reference Figure 2 The bottom of the workbench 1 is fixedly connected to a first motor 602. The output end of the first motor 602 passes through the workbench 1 and is fixedly connected to the bottom of the mounting block 601. The first motor 602 is set to rotate the joint during the spraying process of the clamped stainless steel pipe joint so that the joint can be sprayed all around, thus improving the spraying effect. Reference Figure 2 The moving mechanism 7 includes a mounting frame 701. The bottom of the mounting frame 701 is fixedly connected to the top of the worktable 1. A second motor 704 is fixedly connected to the top of the mounting frame 701. The output end of the second motor 704 passes through the mounting frame 701 and is fixedly connected to a threaded rod 706. A sliding block 703 is threadedly connected to the surface of the threaded rod 706. The surface of the sliding block 703 is fixedly connected to the surface of the arc-shaped spray gun 9. Through the mounting frame 701, the second motor 704, the threaded rod 706 and the sliding block 703, the reverse rotation of the second motor 704 indirectly drives the sliding block 703 to move up and down in the inner cavity of the mounting frame 701, and indirectly drives the arc-shaped spray gun 9 to move up and down, adapting to stainless steel joints with high spraying height. Reference Figure 1 One end of the output pipe 5 is fixedly connected to a flexible hose 702. One end of the flexible hose 702 is fixedly connected to the inner cavity of the arc-shaped spray gun 9. Through the flexible hose 702, a longer flexible connecting pipe is used to connect the output pipe 5 and the arc-shaped spray gun 9, thereby providing a flexible pipe space for the distance generated by the up and down movement of the arc-shaped spray gun 9, so that the arc-shaped spray gun 9 can work normally. Reference Figure 2 The inner cavity of the mounting bracket 701 is provided with a movable groove 705. The inner cavity of the movable groove 705 is movably connected to the surface of the sliding block 703. The movable groove 705 is provided to limit the sliding block 703 and prevent it from rotating. Therefore, when the threaded rod 706 rotates, it can drive the sliding block 703 to move up and down in the inner cavity of the mounting bracket 701.

[0019] Working Principle: First, the PLC program inside the control console 8 controls the paint pump 4, the second motor 704, the cylinder 603, and the first motor 602 to work together. When it is necessary to spray the stainless steel pipe joint, it is first placed around the clamping block 608. Then, the cylinder 603 starts working, and the extension end of the cylinder 603 drives the moving block 604 to move upward. The moving block 604 drives the three rotating shafts 607 connected to it to move upward. These three rotating shafts 607 drive the connecting rod 605 to rotate clockwise to a horizontal position, thereby driving the rotating shaft 607 connected to the inner cavity of the connecting rod 605 to move outward. The rotating shaft 607 drives the connecting block 606 connected to it to push outward, thereby clamping the stainless steel pipe joint from the inside. While the clamping block 608 moves outward, the arrangement of the rotating shaft 607 and the connecting block 606 under its inner cavity causes the lower part of the clamping block 608 to tilt inward due to the force, mainly serving as a support linkage. If the lower half of the clamping block 608 is not connected by a pivot, the clamping block 608 will rotate randomly due to gravity during the clamping process. This will prevent the outer side of the clamping block 608 from engaging the anti-slip pad 609 with the inner diameter of the stainless steel pipe joint, thus affecting the internal support clamping effect. Therefore, the part that mainly contacts the inner diameter of the stainless steel pipe is the upper part of the clamping block 608. When the internal support clamping is complete, the paint pump 4 starts working, drawing paint from the inner cavity of the paint tank 3 through the input end of the paint pump 4, and then pumping the paint through the paint pump... The output end of 4 is output to the inner cavity of the output pipe 5, and then it is delivered to the inner cavity of the hose 702. Finally, the dye will enter the inner cavity of the arc spray gun 9 and be sprayed onto the surface of the stainless steel joint by the nozzle on one side of the arc spray gun 9. During the spraying process, if the joint height is too high, the second motor 704 will start to rotate in both directions during the rotation spraying process, driving the threaded rod 706 to rotate, thereby driving the sliding block 703 to move up and down in the inner cavity of the mounting bracket 701, thereby driving the arc spray gun 9 to move up and down for spraying.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
