[0024] Preferably, a squeezing block 11 is installed at the bottom end of the electric telescopic rod 6 , and the squeezing block 11 forms a lifting connection with the clamping block 5 through the electric telescopic rod 6 .

[0025] Preferably, the clamping block 5 is L-shaped, and the anti-slip pad 7 is made of food-grade rubber material and is fitted and fixed to the inner wall of the clamping block 5 .

[0026] Preferably, the threads on the surfaces of the bidirectional threaded rod 9 correspond to each other, and one end of the bidirectional threaded rod 9 passes through the fixing block 8 and is connected to the output shaft of the servo motor 10 .

[0027] Preferably, a connecting block 12 is installed at the bottom end of the clamping block 5 , and the connecting block 12 is threadedly connected to the surface of the bidirectional threaded rod 9 , so that the clamping block 5 forms a threaded motion through the connecting block 12 and the bidirectional threaded rod 9 .

[0028] In the embodiment, when processing the automobile parts shell, first, the automobile parts shell is placed on the workbench 1 installed inside the four-axis machining center body 14, and then the servo motor 10 is started. At this time, the output shaft of the servo motor 10 rotates to drive the bidirectional threaded rod 9 to rotate between the two fixed blocks 8, followed by the connecting block 12. The thread on the surface of the bidirectional threaded rod 9 moves closer to or away from each other. At the same time, the movement of the connecting block 12 will drive the clamping block 5 to move, and then the clamping block 5 moves on the top surface of the workbench 1 close to the two ends of the automobile parts shell, until the clamping block 5 clamps and fixes the automobile parts shell and stops the servo motor 10, and then starts the electric telescopic rod 6. At this time, the telescopic end of the electric telescopic rod 6 extends out to push the extrusion block 11 close to the top of the automobile parts shell, and then squeezes the automobile parts shell from top to bottom to fit with the top surface of the workbench 1. When the fixation is completed, the four-axis machining center body 14 starts to work and processes the automobile parts shell fixed on the top of the workbench 1.

[0029] Embodiment 2

[0030] See also Figure 1-5 A fixing pin 13 is connected to the bottom end of the workbench 1 , and the extension plate 4 is fixedly connected to the workbench 1 through the fixing pin 13 .

[0031] In the embodiments, according to the description of the first embodiment, when the top surface of the workbench 1 is insufficient, the fixing pin 13 can be rotated to move, releasing the squeezing and fixing of the extension plate 4, and then the extension plate 4 is pulled outward from the inside of the workbench 1, and stops after moving to the specified position, and the fixing pin 13 is rotated again to squeeze and fix the extension plate 4, so that the usable area of ​​the workbench 1 is enlarged through the extension plate 4, and when the automobile accessory shell is placed on the workbench 1, it will not be suspended.

[0032] In summary, according to the description of embodiments one and two, in the process of processing the automobile part shell by the four-axis machining center body 14, it is not only convenient to fix the automobile part shell on the workbench 1, but also realizes the automatic assembly and fixation of the automobile part shell, which reduces the existing process of basically installing the automobile part shell on the workbench 1 for processing by bolts. In this way, the bolts are disassembled for a long time, and the surface threads are prone to wear. At the same time, bolt fixing also requires tools and time, which results in a great waste of processing time and greatly reduces the work efficiency. At the same time, it also reduces the problem of insufficient area of ​​the workbench 1 and inability to stably place the automobile part shell.
