The frame 1 has a driving mechanism for driving the processing table 2 to move, so that the product is fixed on the processing table. After 2, the processing table 2 can move with the product. A moving frame 5 is slidably connected to the gantry frame 3. The moving frame 5 is driven by a moving motor 6. The moving frame 5 is slidably connected to a lifting frame 7 along the vertical direction. The elevating motor 8 of the elevating frame 7 is used to drive the elevating frame 7 to rise and fall, and the length direction of the processing table 2 is defined as the X axis, the extension direction of the gantry 3 is the Y axis, and the vertical direction is the Z axis. A main shaft motor 9 is installed, the main shaft motor 9 is installed on the top of the lifting frame 7, and its working end faces downwards. On a sleeve 12 , the main shaft 11 is provided with a limit step 13 , and the limit step 13 is pressed against the end of the sleeve 12 to limit the axial movement of the main shaft 11 . The sleeve 12 is mounted on an adjustment frame 14 through an angle adjustment mechanism, and the adjustment frame 14 is rotatably installed on the lift frame 7. Therefore, when the adjustment frame 14 rotates along the Z axis, the sleeve 12 also follows the adjustment frame 14. With the rotation, the direction of the axis of the sleeve 12 can be adjusted by the angle adjustment mechanism. In this embodiment, the angle adjustment mechanism can adjust the angle of the sleeve 12 relative to the vertical direction +/- 5°. When the sleeve 12 is adjusted, The direction of the main shaft 11 also changes accordingly. A driven gear 15 is fixed on the top of the adjusting frame 14 , a rotating motor 16 is mounted on the lifting frame 7 , and the working end of the rotating motor 16 is connected with a driving gear 17 that meshes with the driven gear 15 , thus rotating the motor 16 The adjustment frame 14 can be driven to rotate through the engagement of the driving gear 17 and the driven gear 15. The bottom end of the main shaft 11 is installed with a processing tool 18. When this embodiment is used as a gantry machining center, the tool for the machining center can be installed. For example, a milling cutter; when this embodiment is used as a friction stir welding device, a friction stir welding head can be installed.

Specifically, the angle adjustment mechanism includes an adjustment seat 19 , the adjustment seat 19 is fixedly installed on the bottom of the adjustment frame 14 , and the sleeve 12 is rotatably hinged on both sides in the adjustment seat 19 . An expansion sleeve and a locking bolt 20 are provided. When the locking bolt 20 is tightened, the sleeve 12 cannot rotate, and when the locking bolt 20 is loosened, the sleeve 12 can rotate and adjust the angle.
