Description

Technical Field

[0001] The utility model relates to the field of supersonic flame spraying guns, in particular to a cross positioning device suitable for supersonic flame spraying guns. Background Art

[0002] The supersonic flame spraying technology is a technology that heats powder particles to a molten or semi-molten state and sprays them onto the surface of the workpiece with a high-speed airflow to form a coating. Therefore, in order to allow the powder particles to obtain sufficient temperature and speed, the supersonic flame spraying gun will generate extremely high heat when working, and the temperature inside the gun can reach over 2500°C. In order to protect the gun structure, the outer wall of the supersonic flame spraying gun will have a cooling water circulation supply device. The typical structure diagram of the supersonic flame spraying gun is shown below. Figure 1 shown.

[0003] In the invention of CN202122580391.7 "A laser positioning device for supersonic flame spraying", a laser positioning device for a supersonic flame spraying gun is described. The limitations of the above invention are: 1. When the device is used, it is necessary to spray the coating on the plane in advance to form a circular spot, visually determine the center point position of the spray gun, and then align the laser point with the center point position. The method of visually determining the center point has a large error, and it is difficult to ensure the accuracy of the center point position; 2. The device adjusts the position of the laser point through 6 screws, and the adjustment method is complicated. Once the spraying distance of the supersonic flame spraying gun changes, the laser point position must be readjusted, and the convenience of use is poor; 3. The device is installed on the outer wall of the spray gun holster by fastening the upper and lower brackets with screws. Since the shortest barrel size of the spray gun is generally 4 inches, about 10 cm, at this time, the length of the cylindrical section of the outer wall of the holster is difficult to meet the installation requirements of the device, resulting in the device being unusable. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a cross positioning device suitable for a supersonic flame spraying gun.

[0007] The top screw hole one and the top screw hole two are both located at the top of the center bracket, and the axes of the top screw hole one and the top screw hole two must pass through the center of the spray gun muzzle and be perpendicular to the axis of the gun barrel.

[0008] The side screw hole three and the side screw hole four are both located on the side of the center bracket. The axes of the side screw hole three and the side screw hole four must pass through the center of the spray gun muzzle and be perpendicular to the axes of the top screw hole one and the top screw hole two. The intersection of the two vertical and horizontal straight laser lines is the center of the muzzle.

[0009] The front end bracket comprises a baffle, a screw hole five connected to the central bracket, a screw hole six for fixing the one-line laser, and a supporting surface two matched with the one-line laser.

[0010] The screw hole five is aligned with the top screw hole one and the side screw hole three, and are respectively connected by headless screws.

[0011] The rear end bracket comprises a screw hole seven connected to the central bracket, a screw hole eight for fixing the straight laser, and a supporting surface three cooperating with the straight laser.

[0012] The screw hole seven is aligned with the top screw hole two and the side screw hole four, and are respectively connected by headless screws.

[0013] The beneficial effects of the utility model are as follows: after the assembly is completed, no secondary adjustment is required when in use, the cross positioning accuracy is not affected by any adjustment of the spraying process parameters, and the positioning accuracy is high. At the same time, in combination with measuring tools such as a ruler, the cross positioning line can also assist in the accurate measurement of the relative distance between the spray gun and the part; after the spray gun positioning and the spray gun movement path adjustment are completed using the device, the device can be quickly disassembled and is easy to use, thereby realizing simple, fast and accurate positioning of the supersonic flame spraying gun.
