DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] The following will describe in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0031] Please refer to Figures 1 to 5 , a positioning mechanism for steel door spraying provided by an embodiment of the present utility model includes: a working plate 1, an adjusting device 2 is provided on the side of the working plate 1, and an auxiliary device 3 is provided on the inner wall of the working plate 1.

[0032] In an embodiment of the present utility model, please refer to Figure 2 and Figure 3, the adjusting device 2 includes a connecting plate 201. The connecting plate 201 is fixedly connected to the working plate 1. A motor 202 is fixedly connected to one side of the connecting plate 201. The output end of the motor 202 is fixedly connected to a screw rod 203. A threaded ring 204 is threadedly connected to the arc surface of the screw rod 203. A limiting rod 205 is fixedly connected to the side of the working plate 1 away from the connecting plate 201. An adjusting ring 206 is slidably connected to the arc surface of the limiting rod 205. The adjusting ring 206 and the threaded ring 204 are fixedly connected to the same pressing plate 207 on the side close to each other. A rotating rod 209 is threadedly penetrated through the inner wall of the pressing plate 207. A supporting plate 208 is threadedly connected to the arc surface of the rotating rod 209. Two guiding rods 210 are slidably penetrated through the inner wall of the supporting plate 208. One end of each of the two guiding rods 210 is fixedly connected to the pressing plate 207. When painting a steel door, usually the steel door is tilted to form an angle between the steel door and the working plate 1, so that the steel door can lean on the working plate 1, and then the steel door can be painted by a painting device. However, there is no fixed relationship between the steel door and the working plate 1, which also causes the steel door and the working plate 1 to be unstable when placing the steel door for painting and causes the steel door to deviate in angle. The deviated steel door will affect the painting effect of painting the steel door by the painting device, and the steel door with an angle deviation will also injure the feet of the workers near the steel door, resulting in an increased safety risk coefficient during spraying. At this time, the adjusting device 2 can be used to improve the connection effect between the steel door and the working plate 1, so as to improve the painting stability of painting the steel door through the adjusting device 2 and also improve the safety of the workers near the steel door. The end of the rotating rod 209 away from the pressing plate 207 is fixedly connected to a turntable 211. The cross-section of the turntable 211 is circular. When it is necessary to rotate the rotating rod 209, the turntable 211 installed on the rotating rod 209 can be used to rotate the rotating rod 209. The turntable 211 can increase the speed of rotating the rotating rod 209. A plurality of anti-slip grooves 212 are formed on the arc surface of the turntable 211. The plurality of anti-slip grooves 212 are evenly distributed on the arc surface of the turntable 211. When rotating the turntable 211, the anti-slip grooves 212 formed on the turntable 211 can increase the friction between the hand and the turntable 211, so as to improve the stability of rotating the turntable 211 through the anti-slip grooves 212. A connecting pad 213 is fixedly connected to the side of the supporting plate 208 close to the pressing plate 207. The cross-sectional size of the connecting pad 213 is the same as the cross-sectional size of the supporting plate 208. When the supporting plate 208 comes into contact with the steel door, the connecting pad 213 installed on the supporting plate 208 can increase the friction between the supporting plate 208 and the steel door, so as to improve the contact stability between the supporting plate 208 and the steel door through the connecting pad 213;

[0033] In an embodiment of the present invention, please refer to Figure 4 and Figure 5, the auxiliary device 3 includes two sliders 301. The two sliders 301 are respectively fixedly connected to both sides of the inner wall of the working plate 1. On one side of the two sliders 301 close to each other, there is a same adjusting plate 302. The inner walls of the adjusting plate 302 are respectively slidably connected to the two sliders 301. One side of the adjusting plate 302 is fixedly connected to a rotating shaft 303. The side of the rotating shaft 303 away from the adjusting plate 302 is rotatably connected to a connecting frame 304. On one side of the inner wall of the connecting frame 304, there are fixedly connected several springs 309. One end of the several springs 309 away from the connecting frame 304 is fixedly connected to a same connecting plate 308. On the side of the working plate 1 close to the connecting frame 304, there is fixedly connected a fixed block 305. A adjusting rod 306 is threadedly penetrated through the inner wall of the fixed block 305. One end of the adjusting rod 306 close to the adjusting plate 302 is fixedly connected to an abutting block 307. When painting a steel door, the steel door can be rotated by the auxiliary device 3, so that the efficiency and speed of rotating the steel door can be improved through the auxiliary device 3, and the efficiency of painting the whole steel door can be improved through the auxiliary rotation. An auxiliary rod 310 is slidably connected to the inner wall of the spring 309. One end of the auxiliary rod 310 is fixedly connected to the connecting plate 308. The auxiliary rod 310 penetrates through the connecting frame 304 slidably. When the spring 309 is moving, the auxiliary rod 310 installed inside the spring 309 can limit the movement of the spring 309, so that the service life of the spring 309 can be improved through the auxiliary rod 310 limiting the movement of the spring 309. The adjusting rod 306 is a titanium alloy rod. The surface of the rod body of the adjusting rod 306 made of titanium alloy material is relatively hard. This also makes it difficult for the surface of the rod body of the adjusting rod 306 made of titanium alloy material to deform when driving the abutting block 307 to be connected to the adjusting plate 302 in the fixed block 305 for a long time, and the service life is relatively long;

[0034] The working principle of a positioning mechanism for steel door spraying provided by the utility model is as follows: When it is necessary to improve the connection stability between the steel door and the working plate 1, first rotate the rotating rod 209. The rotation of the rotating rod 209 can drive the support plate 208 to adjust along the angle of the guide rod 210, so as to adjust the size between the support plate 208 and the pressing plate 207 according to the thickness of the steel door. After adjusting the size between the support plate 208 and the pressing plate 207 to an appropriate value, the steel door can be placed in the middle position between the pressing plate 207 and the support plate 208. Then, start the motor 202. The movement of the motor 202 will drive the screw rod 203 to rotate. The rotation of the screw rod 203 can drive the pressing plate 207 to move through the threaded ring 204. The adjusting ring 206 installed on the other side of the pressing plate 207 will slide on the limiting rod 205, so as to limit the movement angle of the pressing plate 207 by the sliding of the adjusting ring 206 on the limiting rod 205. Thus, the motor 202 can drive the pressing plate 207 to move towards the steel door, and through the cooperation of the pressing plate 207 and the support plate 208, the steel door can be fixed on one side of the working plate 1. When it is necessary to rotate the rotating rod 209, the turntable 211 installed on the rotating rod 209 can be used to rotate the rotating rod 209. The turntable 211 can increase the rotation speed of the rotating rod 209. When rotating the turntable 211, the anti-slip groove 212 opened on the turntable 211 can increase the friction between the hand and the turntable 211, so as to improve the stability when rotating the turntable 211 through the anti-slip groove 212. When the support plate 208 comes into contact with the steel door, the connecting pad 213 installed on the support plate 208 can increase the contact friction between the support plate 208 and the steel door, so as to improve the contact stability between the support plate 208 and the steel door through the connecting pad 213.

[0035] When painting a steel door, first bring the steel door into contact with the connecting plate 308, and press the steel door towards one side of the connecting frame 304. When the steel door contacts the connecting plate 308, it will drive the spring 309 to wind up. Thus, under the action of the spring 309 and the connecting plate 308, the steel door can be temporarily restricted within the connecting frame 304. When it is necessary to rotate the steel door to paint the other side of the steel door, rotate the adjusting rod 306 within the fixed block 305. The movement of the adjusting rod 306 can drive the abutting block 307 to move away from the adjusting plate 302. When the abutting block 307 disengages from the adjusting plate 302, the adjusting plate 302 can slide on the two sliders 301. By sliding the adjusting plate 302, the steel door can be driven to move until the adjusting plate 302 drives the steel door to move to the required rotation space size. Then, the steel door can be rotated through the rotating shaft 303, so that the rotation of the steel door can be completed through the rotating shaft 303, thereby improving the painting efficiency of the steel door. When the spring 309 moves, the auxiliary rod 310 installed inside the spring 309 can limit the movement of the spring 309. Thus, the movement of the spring 309 can be limited through the auxiliary rod 310 to improve the service life of the spring 309. The rod surface of the adjusting rod 306 made of titanium alloy is relatively hard. This also makes it difficult for the rod surface of the adjusting rod 306 made of titanium alloy to deform when it drives the abutting block 307 to connect with the adjusting plate 302 within the fixed block 305 for a long time, and its service life is relatively long.

[0036] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here too much.

[0037] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
