Description

Technical Field

[0001] This utility model relates to a spraying device, and more particularly to a tungsten carbide powder wear-resistant layer spraying device, belonging to the field of tungsten carbide spraying technology. Background Technology

[0002] Tungsten carbide powder wear-resistant coating is an advanced process for preparing high-hardness, high-wear-resistant coatings on metal surfaces using thermal spraying technology. It primarily employs techniques such as supersonic flame spraying, plasma spraying, or explosive spraying to heat and accelerate tungsten carbide-based powder, which is then deposited at high speed onto the substrate surface, forming a dense, low-porosity reinforced layer. This process, combined with substrate sandblasting pretreatment and precise parameter control, enables the coating to possess both excellent bonding strength and ultra-high temperature wear resistance, making it widely applicable to critical wear-resistant components in machinery, energy, aerospace, and other fields.

[0003] Existing tungsten carbide powder wear-resistant coating equipment faces significant operational limitations when spraying multiple surfaces. Traditional equipment often uses a fixed turntable or simple tooling to hold the workpiece, and its degree of freedom of rotation is insufficient to achieve full coating of irregularly shaped or large-sized workpieces. Frequent manual adjustments to the clamping posture are required, leading to a decrease in coating efficiency. To address this, a tungsten carbide powder wear-resistant coating equipment is proposed.

[0030] The adjustment assembly 30 includes a second motor 31, a bidirectional lead screw 32, a bracket 33, a third motor 34, and a clamping plate 35. The output shaft of the second motor 31 is fixedly connected to one end of the bidirectional lead screw 32. Two brackets 33 are symmetrically threaded to the outer side wall of the bidirectional lead screw 32. The third motor 34 is installed on one side of the bracket 33. The output shaft of the third motor 34 is fixedly connected to one side of the clamping plate 35. The clamping plate 35 is rotatably connected to one side of the bracket 33. After single-sided spraying is completed, the second motor 31 works, the clamping plate 35 releases the workpiece, the hydraulic cylinder 23 lifts the rotary table 26, the clamping plate 35 clamps the workpiece again after the workpiece is lifted, the rotary table 26 resets, and the third motor 34 drives the clamping plate 35 and the workpiece to flip, completing the side spraying. If it is necessary to spray the surface in contact with the clamping plate 35, the first motor 25 drives the rotary table 26 to rotate after lifting, changing the angle of the workpiece and re-clamping it.

[0031] In this embodiment, specifically: the spraying assembly 10 includes a housing 11 and a first electric guide rail 12;

[0032] The top of the inner wall of the housing 11 is symmetrically equipped with a first electric guide rail 12, and a controller 18 is installed on one side of the housing 11. The controller 18 is used to control the working status of the spraying device. At the same time, a vision recognition system is installed in the controller 18, which can recognize the image data of the workpiece and analyze the coordinate points of the spraying area.

[0033] In this embodiment, specifically: two third electric guide rails 21 are symmetrically installed on the bottom of the inner side wall of the housing 11. The third electric guide rails 21 drive the base plate 22 to move so as to place the workpiece.

[0034] In this embodiment, specifically: the second motor 31 is installed on one side of the housing 11, the bidirectional lead screw 32 is rotatably connected to the inner wall of the housing 11, and the two brackets 33 are symmetrically slidably connected to the inner wall of the housing 11. When the bidirectional lead screw 32 rotates, it drives the two brackets 33 to move synchronously through the threaded engagement.

[0035] In this embodiment, specifically: the bottom of the first electric guide rail 12 is slidably connected to a slide table 13, and the first electric guide rail 12 and the second electric guide rail 14 are composed of a servo motor, a lead screw module and a slide rail, used to achieve precise linear motion.

[0038] In this embodiment, specifically: a positioning camera 16 and a spray gun 17 are installed at the bottom of the slide 15. The positioning camera 16 captures images of the workpiece and sends the images to the controller 18. The visual recognition system in the controller 18 analyzes the captured image data and determines the position coordinates of the spraying area.

[0039] In operation, the workpiece is placed on the rotary table 26. The second motor 31 drives the bidirectional lead screw 32 to rotate, causing the support 33 to move relative to it. The clamping plate 35 holds the workpiece to facilitate the spraying process. Before spraying, the positioning camera 16 captures an image of the workpiece and sends the image to the controller 18. The visual recognition system in the controller 18 analyzes the image to determine the position of the spraying area. The first electric guide rail 12 and the second electric guide rail 14 move the spray gun 17 to spray the workpiece surface. After spraying, the second motor 31 operates, the clamping plate 35 releases the workpiece, the hydraulic cylinder 23 lifts the rotary table 26, and the clamping plate 35 clamps the workpiece again after the workpiece is lifted. The rotary table 26 resets, and the third motor 34 drives the clamping plate 35 and the workpiece to flip, completing the side spraying. If the surface in contact with the clamping plate 35 needs to be sprayed, the first motor 25 drives the rotary table 26 to rotate after lifting, changing the angle of the workpiece and re-clamping it, so as to complete the multi-sided spraying of the workpiece. There is no need for the operator to manually adjust the clamping posture, thus improving the spraying efficiency.
