Description

Technical Field

[0001] This utility model relates to the technical field of mechanical manufacturing processes, and in particular to a precision controller for arc spraying. Background Technology

[0002] Arc spraying is a thermal spraying technology used to form protective or functional coatings on the surface of a substrate. It involves melting a metal wire using an electric arc and spraying it onto the workpiece surface to form a coating. Typically, a pair of metal wires (usually made of the same material) are used as consumable electrodes. These two wires melt under the action of the electric arc, and the molten metal is atomized into fine particles by compressed air or other gases and sprayed onto the substrate surface at high speed. However, after spraying, residual welding wire remains liquefied due to the residual temperature inside the spray gun and is sprayed onto the workpiece through residual gas. Precise control of stopping the welding wire spraying is impossible, affecting the coating quality of the final part of the workpiece. Therefore, this application proposes a precision controller for arc spraying. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art where, after spraying, residual welding wire remains liquefied due to the residual temperature inside the spray gun and is sprayed onto the workpiece via residual gas. This makes it impossible to precisely control the stopping of the welding wire spraying, thus affecting the spraying quality of the last part of the workpiece. The invention proposes a precision controller for arc spraying.

[0004] The technical solution of this utility model is: an arc spraying precision controller, including a housing and a drive mechanism fixed to one side of the inner wall of the housing. The drive mechanism includes a drive motor fixed to one side of the housing, and the output end of the drive motor is provided with a wire feeding mechanism.

[0005] A guide cutting mechanism is provided on one side of the outer wall of the box. The guide cutting mechanism includes multiple limiting rods that are slidably connected to one side of the outer wall of the box. A sliding support frame is fixedly connected to the side of the multiple limiting rods away from the box. A bending mechanism is provided on one side of each of the two sliding support frames.

[0006] The outer walls of the two sliding support frames are engaged with fixing blocks, and the ends of the fixing blocks away from the sliding support frames are fixedly connected to a shearing mechanism.

[0007] Optionally, the transmission wire feeding mechanism includes a drive rod fixed to the output end of the drive motor. A drive wheel 1 passes through one side of the outer wall of the drive rod. A transmission belt is sleeved on the outer wall of the drive wheel 1. A drive wheel 2 is connected to the inner wall of the transmission belt away from the drive wheel 1. A drive gear is fixedly connected to one side of both the drive wheel 2 and the drive wheel 1.

[0008] Optionally, a driven gear is meshed on one side of the outer wall of each of the two driving gears, and a driven rod passes through one side of each of the two driven gears.

[0009] Optionally, a guide wheel is fixedly connected to the outer wall of the upper driven rod and the lower driving rod, and a bending wheel is fixedly connected to the outer wall of the upper driving rod and the lower driven rod, with a welding wire provided between the two bending wheels and the guide wheel.

[0010] Optionally, the bending mechanism includes multiple connecting rods fixed to one side of the sliding support frame, and bending wheels are rotatably connected to the inner walls of the multiple connecting rods.

[0013] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] This invention utilizes a transmission wire feeding mechanism to initially bend the welding wire during the feeding process, preventing the wire from getting stuck inside the device due to angle issues and hindering its feeding. When the device is no longer in use and spraying is no longer required, the electric telescopic rod in the guide cutting mechanism drives the cutter to cut the welding wire, preventing waste and liquefaction, and ensuring proper spraying onto the workpiece. This allows for better control of residual spraying material and quality, and facilitates operation. Attached Figure Description

[0026] Example

[0027] like Figure 1 and Figure 2 As shown, the present invention proposes a precision controller for arc spraying, comprising a housing 1 and a drive mechanism 2 fixed to one side of the inner wall of the housing 1. The drive mechanism 2 includes a drive motor 21 fixed to one side of the housing 1, and a transmission wire feeding mechanism is provided at the output end of the drive motor 21. Specifically, the transmission wire feeding mechanism includes a drive rod 24 fixed to the output end of the drive motor 21. A drive wheel 22 passes through one side of the outer wall of the drive rod 24. A transmission belt 23 is sleeved on the outer wall of the drive wheel 22. A drive wheel 211 is connected to the inner wall of the transmission belt 23 away from the drive wheel 22. A drive gear 25 is fixedly connected to one side of both the drive wheel 211 and the drive wheel 22. The drive motor 21 drives the drive rod 24 to rotate, thereby causing the transmission belt 23 to drive the drive wheel 22 and the drive wheel 211 to rotate simultaneously. This causes the two drive gears 25 to drive the meshing driven gear 27 to rotate. Both driven gears 27 are meshed on one side, and driven rods 26 pass through one side of each driven gear 27. Guide wheels 29 are fixedly connected to the outer walls of the upper driven rod 26 and the lower driven rod 24. Bending wheels 28 are fixedly connected to the outer walls of the upper driven rod 24 and the lower driven rod 26. Welding wire 210 is arranged between the two bending wheels 28 and the guide wheels 29. The rotation of the driven gears 27 causes the driven rods 26 to drive the bending wheels 28 and the guide wheels 29, which mesh and rotate with the bending wheels 28 and the guide wheels 29 driven by the drive rod 24, thereby bending the welding wire 210 entering the device, facilitating subsequent guidance and heating, and preventing jamming.

[0028] It should be added that, such as Figure 1 and Figure 4As shown, a guide cutting mechanism 3 is provided on one side of the outer wall of the housing 1. The guide cutting mechanism 3 includes multiple limiting rods 31 slidably connected to one side of the outer wall of the housing 1. By setting multiple limiting rods 31, the guide cutting mechanism 3 can be limited in its operation. A sliding support frame 32 is fixedly connected to the side of the multiple limiting rods 31 away from the housing 1. By setting the sliding support frame 32, the bending mechanism is supported. A bending mechanism is provided on one side of each of the two sliding support frames 32. The bending mechanism includes multiple connecting rods 34 fixed to one side of the sliding support frame 32. Each connecting rod 34 has a bending wheel 35 rotatably connected to its inner wall. Two electric telescopic rods 33 are fixedly connected between the two sliding support frames 32. The telescopic movement of the two electric telescopic rods 33 drives the two sliding support frames 32 to slide accordingly, thereby driving the connecting rod 34 and the bending wheel 35 to move towards the guide plate 39. The rotation of the bending wheel 35 causes the welding wire 210 to bend between the guide plate 39 and the bending wheel 35, which is more suitable for the curvature of the guide plate 39, making it easier to perform subsequent arc heating and preventing it from getting stuck inside the device.

[0029] Another point that needs to be described is, for example Figure 1 and Figure 4 As shown, the outer walls of the two sliding support frames 32 are fitted with fixing blocks 36. The ends of the fixing blocks 36 away from the sliding support frames 32 are fixedly connected to a shearing mechanism. The shearing mechanism includes a bearing plate 37 fixed to one side of the fixing blocks 36. A cutter 38 is fixedly connected to one side of the two bearing plates 37, and a spring rod 310 is fixedly connected between the two bearing plates 37. The outer wall of the housing 1 is hinged to two guide plates 39. Both guide plates 39 are located on one side of the cutter 38. When the device is not in use, the sliding support frame 32 is slid by the electric telescopic rod 33, which in turn drives the two bearing plates 37 to slide. The bearing plates 37 drive the cutter 38 to cut the welding wire 210 on the guide plates 39, preventing further spraying and making the control more precise.

[0030] The working principle of this embodiment is as follows: In use, the driven gear 27 rotates, causing the driven rod 26 to drive the bending wheel 28 and guide wheel 29. The bending wheel 28 and guide wheel 29 driven by the drive rod 24 mesh and rotate, bending the welding wire 210 entering the device to facilitate subsequent guiding and heating, and preventing jamming. The extension and retraction of the two electric telescopic rods 33 drives the two sliding support frames 32 to slide accordingly, thereby driving the connecting rod 34 and the bending wheel 35 to move. The wire 210 moves towards the guide plate 39, and the bending wheel 35 rotates, causing the welding wire 210 to bend between the guide plate 39 and the bending wheel 35. This better adapts to the curvature of the guide plate 39, facilitating subsequent arc heating and preventing it from getting stuck inside the device. At the same time, the electric telescopic rod 33 drives the sliding support frame 32 to slide, thereby driving the two bearing plates 37 to slide. The bearing plates 37 drive the cutter 38 to cut the welding wire 210 on the guide plate 39, preventing further spraying and making the control more precise.

[0031] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
