[0018] 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4 This utility model discloses a gantry machining center with automatic workpiece centering function, comprising a processing chamber 1, with a rotating door 2 hinged to one end of the processing chamber 1, providing a convenient workpiece loading and unloading channel, simplifying operation and improving processing efficiency; a mounting frame is provided inside the processing chamber 1, with two pairs of bottom rods symmetrically fixed to the top surface of the mounting frame, ensuring the stability and reliability of the entire machining center structure and enabling the components to work together; two support plates are provided on the top of the mounting frame, each equipped with an electric push cylinder 8, which allows for precise control of the movement distance and speed of the crossbeam 7, achieving rapid and accurate centering of the workpiece; a support block is fixed between the two support plates, with a centering component 11 on the support block, and a placement platform 3 at the top of the centering component, ensuring the stability of the workpiece during processing and improving processing accuracy and quality.

[0020] In this utility model, the base rod 4 is provided with two pairs of slide rails 5, and multiple positioning pins for fixing the base rod 4 are inserted equidistantly inside the slide rails 5. The slide rails 5 facilitate the smooth movement of the crossbeam 7, providing a basis for the automatic centering operation of the workpiece. Two pairs of moving blocks 6 slide symmetrically on the two pairs of slide rails 5, and a crossbeam 7 is provided between each pair of moving blocks 6. Multiple limiting blocks 13 are welded equidistantly on the crossbeam 7, and a protective film is attached to one side of the limiting block 13. A connecting shaft is provided at the top middle section of the crossbeam 7. The crossbeam 7 facilitates the positioning and limiting of workpieces of different sizes, ensuring the stability and accuracy of the workpiece during processing. The centering component includes a support shaft 11 provided on the support block, a rotating plate 10 rotatably provided on the support shaft 11, two connecting blocks at both ends of the rotating plate 10, and a first connecting rod 1 rotatably provided on one connecting block. 2. A second connecting rod is rotatably mounted on another connecting block. One end of the first connecting rod 12 and the second connecting rod are rotatably connected to two connecting shafts, respectively. The rotating plate 10 facilitates the conversion of motion mode, so that the power of the electric push cylinder 8 can be effectively transmitted to the crossbeam 7, ensuring the realization of the workpiece automatic centering function. The protruding end of the electric push cylinder 8 is threadedly connected to a fixing block 9, which is sleeved on one side of a crossbeam 7. The top of the fixing block 9 is provided with a bolt for fixing. The fixing block 9 facilitates the reliable connection between the electric push cylinder 8 and the crossbeam 7, so that the electric push cylinder 8 can effectively drive the crossbeam 7 to move. A fixing column is fixedly connected to the bottom of the placement platform 3, and the top of the fixing column is fixedly connected to one end of the bottom rod 4. The placement platform 3 provides a stable support platform for the workpiece, ensuring that the position of the workpiece is fixed during the processing.

[0021] Working Principle: When using this utility model, the operator first opens the rotating door 2 and places the workpiece to be processed on the placement table 3. Then, after starting the automatic centering program, the electric push cylinder 8 receives the command from the control system and begins to work. The telescopic rod of the electric push cylinder 8 extends, and since its extended end is tightly connected to the fixed block 9 through threads, the fixed block 9 is pushed accordingly. The fixed block 9 is sleeved on one side of the crossbeam 7 and fixed by the top bolt, thus the thrust of the electric push cylinder 8 can be stably transmitted to the crossbeam 7. The crossbeam 7 is connected to the moving block 6, and the moving block 6 can slide in the slide rail 5 on the bottom rod 4. Positioning pins are pre-inserted at equal intervals on the slide rail 5. These positioning pins are like precision rulers, which can accurately limit the sliding stroke of the moving block 6. When the electric push cylinder 8 pushes the crossbeam 7, the moving block 6 slides smoothly in the slide rail 5 along the path limited by the positioning pins, ensuring the accuracy of the movement of the crossbeam 7. The centering component starts to operate, and the support shaft 11 is installed on the support block and rotates. Plate 10 is mounted on support shaft 11 and can rotate flexibly. As electric push cylinder 8 pushes crossbeam 7 to move, the distance between the connecting shaft on crossbeam 7 and the connecting block at one end of rotating plate 10 changes. Taking the end connected to the first connecting rod 12 as an example, when crossbeam 7 moves outward, the first connecting rod 12 is subjected to outward pulling force. This pulling force is transmitted to rotating plate 10, causing it to rotate around support shaft 11. The connecting block at the other end of rotating plate 10 drives the second connecting rod to move synchronously. The synergistic effect of the two connecting rods enables the two crossbeams 7 to move symmetrically. Finally, the limiting blocks 13, which are welded at equal intervals on crossbeam 7, have a protective film attached to their surface to prevent scratches when in contact with the workpiece. As crossbeam 7 moves, the limiting blocks 13 gradually approach the workpiece. When the limiting blocks 13 on both sides contact the workpiece at the same time, the workpiece is accurately positioned at the preset center position of the gantry machining center, completing the automatic centering operation. Thus, the use of the gantry machining center with automatic workpiece centering function ends.
