[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figures 1-4In this utility model, an automatic centering and positioning device for processing elevator door panels includes a base 1. Parallel linear drive rails 2 are fixedly installed on both sides of the top of the base 1. An I-beam frame 3 is movably installed between the two linear drive rails 2. A horizontal drive rail 4 is installed at the bottom of the I-beam frame 3. A grinding machine 5 is movably installed on the horizontal drive rail 4. A platform 6 is fixedly installed on the base 1. A lifting mechanism 7 is installed inside the platform 6. Two symmetrically distributed side-pushing mechanisms 8 are installed on the I-beam frame 3. A positioning block 9 is fixedly connected to one end of the back of the platform 6. A vertical hydraulic cylinder 10 is fixedly installed at the front end of the platform 6. An infrared rangefinder 11 is fixedly installed at the movable end of the vertical hydraulic cylinder 10. The output end of the infrared rangefinder 11 is perpendicular to the front of the positioning block 9.

[0022] In this invention, the base 1 serves as the device support. During use, one end of the door panel is first pushed towards the positioning block 9 on the platform 6, making it contact the positioning block 9. Then, the door panel is placed flat on the platform 6. Next, the vertical hydraulic cylinder 10 is activated to lift the infrared rangefinder 11, aligning the transmitter of the infrared rangefinder 11 with the front end of the door panel. The distance is then measured. After measurement, the length of the door panel is obtained by subtracting the measured distance from the midpoint between the positioning block 9 and the transmitter of the infrared rangefinder 11. The position of the central axis is then determined. Finally, the side-pushing mechanisms 8 on both sides are activated to move synchronously and center the door panel from both sides. Mechanism 8 calculates the door panel width by summing the two moving distances of the total distance detection. It then automatically adjusts the position of the door panel to the center of the platform 6 and positions the data to the center point of the door panel. This enables the device to automatically center and calibrate the door panel, achieving automated operation, labor-saving and efficient operation, and high precision. It solves the problem in the existing technology where, when using automatic grinding equipment for surface grinding, the door panel needs to be fixed first, and its position needs to be manually adjusted to center it so that the grinding unit can be calibrated before automatic grinding. However, manually adjusting the door panel position is laborious, inefficient, and has low precision.

[0023] Please see Figure 2 The lifting mechanism 7 includes a bottom hydraulic cylinder 71, a lifting plate 72, and two rotating rollers 73. The bottom hydraulic cylinder 71 is fixedly installed inside the platform 6, and the top of the bottom hydraulic cylinder 71 is fixedly connected to the lifting plate 72. The two rotating rollers 73 are rotatably installed on the top of the lifting plate 72, and the outer side of the lifting plate 72 is slidably connected to the inside of the platform 6.

[0024] In this invention, the lifting plate 72 is moved vertically by starting the bottom hydraulic cylinder 71, which in turn moves the rotating roller 73 vertically to contact the bottom of the door panel and pushes the door panel up, reducing the resistance when the door panel is moved laterally, avoiding scratches and protecting the surface of the door panel.

[0025] Please see Figure 4The platform 6 has two rectangular slots 61, and two rotating rollers 73 are aligned and engaged with the two rectangular slots 61 respectively.

[0026] In this invention, the rectangular groove 61 causes the rotating roller 73 to move upward and protrude from the upper surface of the platform 6, thereby lifting the door panel.

[0027] Please see Figure 2 and Figure 3 The side pushing mechanism 8 includes a side cylinder 81, a moving frame 82 and two contact rollers 83. The side cylinder 81 is fixedly installed on the I-beam frame 3, and the movable end of the side cylinder 81 is fixedly connected to the moving frame 82. The contact rollers 83 are rotatably installed on the moving frame 82.

[0028] In this invention, the side cylinder 81 is activated to drive the moving frame 82 to move laterally, thereby driving the contact roller 83 to contact and push the door panel to move laterally, so that the door panel can be centered left and right.

[0029] Please see Figure 2 The contact roller 83 is vertically arranged, and the outer surface of the contact roller 83 is provided with a wear-resistant layer 831.

[0030] In this invention, a wear-resistant layer 831 is provided on the outer surface of the contact roller 83 to increase its service life and reduce errors caused by wear.

[0031] Please see Figure 1 and Figure 3 Two dustproof elastic covers 31 are installed on the outer sides of both downward ends of the I-beam 3. The end of the dustproof elastic cover 31 away from the I-beam 3 is fixedly installed to the end of the linear drive rail 2.

[0032] In this invention, the dustproof elastic cover 31 is used to prevent dust from entering the linear drive rail 2 when the I-beam 3 moves on the linear drive rail 2.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
