The two guide sliders 301 are respectively slidably connected to the two guide slide rails 202, so that the supporting plate 3 can move forward. At the same time, the two guide sliders 301 slide on the two guide slide rails 202 to guide the supporting plate 3. The rear ends of the two guide slide rails 202 are commonly fixedly connected to a back plate 204, a rectangular groove 201 is arranged in the middle of the upper end of the support platform 2, and a hydraulic rod 205 is arranged in the middle of the front end of the back plate 204 and at the upper end of the rectangular groove 201. The hydraulic rod 205 The rear end is fixedly connected to the middle part of the front end of the back plate 204, and the front end of the lower end surface of the supporting plate 3 is fixedly connected to a pushing plate 302, and the telescopic end of the front end of the hydraulic rod 205 is fixedly connected to the middle part of the rear end surface of the pushing plate 302, and the hydraulic rod 205 pushes the pushing plate 302 to move forward, thereby causing the pushing plate 302 to drive the supporting plate 3 to move forward and move out of the upper end of the supporting base plate 1, and by installing workpiece positioning tooling on the upper ends of the two supporting plates 3, the workpiece to be processed is fixed, and a circular limiting groove 203 is provided in the middle part of the inner part of the guide slide rail 202, and guide rods 303 are fixedly connected to both sides of the rear end surface of the pushing plate 302, and the rear ends of the two guide rods 303 are respectively inserted into the circular limiting grooves 203 of the two guide slide rails 202, and the movement of the pushing plate 302 synchronously drives the two guide rods 303 to telescope along the two circular limiting grooves 203 respectively, so as to guide the pushing plate 302.

[0024] See also Figure 2-Figure 4A mobile gantry 4 is arranged in the middle of the upper end of the supporting base plate 1, and a processing device 401 is connected to one side of the upper end of the mobile gantry 4. The front and rear ends of the lower end of the mobile gantry 4 are fixedly connected with a driving slider 402, and the front and rear ends of the upper end surface of the supporting base plate 1 are fixedly connected with a linear guide rail 101. The two driving sliders 402 at the lower end of the mobile gantry 4 are respectively slidably connected between the two linear guide rails 101, and the driving device of the driving slider 402 drives the driving slider 402 to slide on the linear guide rail 101, thereby realizing the horizontal movement of the mobile gantry 4 on the upper end of the supporting base plate 1, and the hydraulic rod 205 on the side support platform 2 pushes the supporting plate 3 to move forward and move out of the upper end of the supporting base plate 1, so that the workpiece can be fixed. On the fixed tooling installed on the supporting plate 3, after the workpiece is fixed, the supporting plate 3 is pulled backward and returned to the upper end of the platform 2 by the hydraulic rod 205, and the driving slider 402 is driven to move by the driving device, so that the movable gantry 4 is moved to the upper end of the supporting plate 3 where the workpiece is fixed, so that the processing device 401 processes the workpiece. At the same time, the supporting plate 3 on the platform 2 on the other side can extend forward to support the upper end of the base plate 1 to fix the next workpiece to be processed, and then retreat to the platform 2 after fixing. After processing the workpiece on one side, the processing device 401 moves to the upper end of the supporting plate 3 on the other side for processing. The workpiece that has completed the processing operation is loaded and unloaded by extending the supporting plate 3 forward, so that the two processing areas can operate interactively, thereby improving the processing efficiency of the workpiece.

[0025] Working principle: When in use, first, install the workpiece positioning tooling on the support plate 3 on one side and fix the workpiece to be processed. Through the telescopic action of the hydraulic rod 205, the support plate 3 together with the workpiece thereon is pushed to slide forward along the guide rail 202 to the outside of the support base plate 1, so that the operator can install and disassemble the workpiece. After the workpiece is fixed, the hydraulic rod 205 contracts to pull the support plate 3 and the workpiece thereon back to the processing position above the support base plate 1. At this time, the mobile gantry 4 slides on the linear guide rail 101 through the driving slider 402 at its lower end, moves to the top of the support plate 3 with the workpiece, and uses the processing device 401 thereon to accurately process the workpiece. At the same time, the support plate 3 on the other side is in an idle state, and the operator can install and fix the next workpiece during this period. When the workpiece on one side is processed, the mobile gantry 4 quickly moves to the support plate 3 on the other side to continue processing, and the support plate 3 where the previously processed workpiece is located is pushed out again by the hydraulic rod 205 to remove the processed workpiece and load the new workpiece to be processed. This interactive operation mode ensures that the gantry machining center can carry out processing operations uninterruptedly while achieving efficient loading and unloading of workpieces, thereby significantly improving the overall processing efficiency.
