[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figures 1 to 7 As shown, a precise arc spraying device 1 includes a base 10, an arc spraying device 1, and two clamping devices 2. The arc spraying device 1 is installed on the top of the base 10, and the two clamping devices 2 are symmetrically arranged and installed on the top of the base 10.

[0028] The arc spraying device 1 includes a spraying frame 121, an inner gear ring 122, two annular moving mechanisms 13 and two linear moving mechanisms 14. The spraying frame 121 is arranged on the top of the base 10, and the inner gear ring 122 is fixedly connected to the inside of the spraying frame 121. The annular moving mechanism 13 is installed on one side of the inner gear ring 122 and the spraying frame 121, and the linear moving mechanism 14 is installed on the other side of the annular moving mechanism 13. A scanner 16 is installed on one of the linear moving mechanisms 14, and an arc spray head 17 is installed on the other linear moving mechanism 14. Through the arrangement of structures such as the transmission motor 131 and the scanner 16, and through the coordinated work of the transmission motor 131, the scanner 16 and the arc spray head 17, all-round and precise spraying of the workpiece is achieved. The annular moving mechanism 13 and the limit design ensure stability and accuracy during the spraying process. At the same time, the three-dimensional model scanning function of the scanner 16 enables the spray head to intelligently adjust its position to adapt to changes in the shape of the workpiece, further improving the spraying effect.

[0029] like Figures 1 to 5As shown, the annular moving mechanism 13 includes a transmission motor 131 and a first side limit block 136. The first side limit block 136 is slidably assembled inside the spray frame 121. Three symmetrically arranged first auxiliary rotating balls 137 are rotatably installed inside the first side limit block 136. The transmission motor 131 is installed at the bottom of the first side limit block 136. The output end of the transmission motor 131 is connected to a coaxially arranged rotating shaft 132 through a coupling. A rotating gear 133 is fixedly sleeved on the outer peripheral surface of the rotating shaft 132. The rotating gear 133 is engaged with the inner gear ring 122. A top rotating frame 134 is installed on the top of the rotating shaft 132. A number of rotating balls 135 evenly distributed around the circumference are rotatably installed on the outer peripheral surface of the top rotating frame 134.

[0030] like Figures 1 to 6 As shown, the linear motion mechanism 14 includes a second side limit block 143 and a cylinder 15. The second side limit block 143 is slidably assembled on the other side of the spray frame 121. Three symmetrically arranged second auxiliary rotating beads 144 are rotatably installed inside the second side limit block 143. One side of the second side limit block 143 is fixedly connected to a follower frame 141. The bottom of the follower frame 141 is fixedly connected to a top plate 142. The top plate 142 is movably sleeved on the outer circumferential surface of the top rotating frame 134. The cylinder 15 is installed on one side of the follower frame 141. A connecting plate 151 is installed at the output end of the cylinder 15. The scanner 16 and the arc spray head 17 are respectively installed inside the two connecting plates 151.

[0031] In this embodiment, when the equipment needs to be sprayed, the two arc spraying devices 1 are turned on at the same time. The arc spraying device 1 is turned on by simultaneously turning on the transmission motor 131, the scanner 16 and the arc spraying head 17. When the transmission motor 131 rotates, it drives the rotating shaft 132 to rotate. The rotation of the rotating shaft 132 is driven by the engagement of the rotating gear 133 thereon with the inner gear ring 122, driving the transmission motor 131 to follow the position of the inner gear ring 122 for circular displacement. During the displacement process, the top plate 142 is sleeved on the top rotating frame 134, and then the auxiliary circular movement is performed by the rotating ball 135. During the movement of the transmission motor 131 and the top plate 142, the first side limit block 136 and the second side limit block 143 on one side thereof are used. A limit is placed on the spray frame 121 to limit its moving position. During the movement, the first auxiliary rotating bead 137 and the second auxiliary rotating bead 144 assist in its movement. During the movement of the annular moving mechanism 13, the cylinder 15 on one side of the scanner 16 is turned on according to the size of the workpiece. The start of the cylinder 15 makes the scanner 16 closer to the workpiece, and the scanner 16 performs a three-dimensional model scan on the workpiece. The scanned shape is sent to the external controller through signal transmission. After calculation, the controller turns on the cylinder 15 on one side of the arc spray head 17. The start of the cylinder 15 allows the position of the arc spray head 17 to change with the change of the workpiece shape, thereby making the spraying position of the arc spray head 17 more accurate.

[0032] Example 2

[0033] like Figures 1 to 7 As shown, the clamping device 2 includes a clamping seat 21 and a second screw motor 22. The clamping seat 21 is fixedly connected to the top of the base 10. The second screw motor 22 is installed inside the clamping seat 21. The output end of the second screw motor 22 is connected to a coaxial transmission shaft 221 through a coupling. A bidirectional screw 222 is fixedly connected to the rotating shaft 132. Two symmetrically arranged clamping frames 23 are movably sleeved on the bidirectional screw 222. Through the arrangement of the second screw motor 22, the bidirectional screw 222 and other structures, the bidirectional screw 222 is driven by the second screw motor 22 to achieve fast and accurate movement of the clamping frame 23, ensuring that the workpiece is firmly clamped. At the same time, the first screw motor 11 drives the transmission screw 111, driving the arc spraying device 1 to stably move, thereby improving the stability of the equipment.

[0034] like Figure 1~Figure 2 As shown, two symmetrically arranged first screw motors 11 are installed inside the base 10, and a transmission screw 111 is installed at the output end of the first screw motor 11. A limiting sliding block 12 is movably sleeved on the outer peripheral surface of the transmission screw 111, and the spray frame 121 is fixedly connected to one side of the two limiting sliding blocks 12.

[0035] like Figures 1 to 7 As shown, a multi-stage clamping block 231 is fixedly connected to one side of the clamping frame 23 .

[0036] In this embodiment, before arc spraying, the workpiece is first placed between the two clamping frames 23. The clamping frame 23 has multiple clamping blocks, which can adapt to workpieces of different diameters. After the workpiece is placed, the second screw motor 22 is turned on. The rotation of the second screw motor 22 causes the transmission shaft 221 to rotate. The rotation of the transmission shaft 221 drives the bidirectional screw 222 to rotate. The rotation of the bidirectional screw 222 causes the two clamping frames 23 to move toward the workpiece to clamp the workpiece. When the arc spraying device 1 is in use, the two first screw motors 11 are turned on synchronously. The rotation of the first screw motor 11 causes the transmission screw 111 to rotate. The rotation of the transmission screw 111 drives the arc spraying device 1 to move through the limiting sliding block 12, thereby improving the stability of the equipment.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
