[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A CNC gantry milling machine fixture with an anti-offset structure includes a worktable 1. Several T-slots 2 are arranged side-by-side on the top of the worktable 1. A T-block 3 is movably installed on the left side of the worktable 1, inside the T-slots 2. A limit mechanism is provided at the top of the T-block 3, including a U-block 9. The U-block 9 is fixedly connected to the top of the T-block 3, and an eccentric wheel 10 is movably installed inside the U-block 9. The limit mechanism also includes a transmission housing 11, which is fixedly installed on the top of the T-block 3. A worm gear 12 is movably installed on the right side of the transmission housing 11, and a [missing information - likely a device or mechanism] is movably installed inside the transmission housing 11, to the right of the worm gear 12. A worm 13 meshes with a worm gear 12. A knob 14 is fixedly installed at the tail end of the worm 13. The bottom end of the worm gear 12 is fixedly connected to the eccentric wheel 10. Two I-beams 4 are movably installed on the right side of the worktable 1 and inside the T-slot 2. A clamping mechanism is provided between the top ends of the two I-beams 4. The clamping mechanism includes a screw 5. The screw 5 is fixedly installed at the top middle part of the I-beams 4. A clamping plate 6 is movably installed between the two screws 5. Nuts 7 are threadedly connected to the outside of the two screws 5 and at the upper end of the clamping plate 6. A movable groove 8 is opened in the middle of the clamping plate 6. The movable groove 8 is movably sleeved with the screw 5. The two I-beams 4 and the T-slot 3 are arranged in a triangle.

[0025] In this embodiment, by setting a limiting mechanism and a clamping mechanism, the left and right sides of the workpiece can be limited and clamped simultaneously. The clamping mechanism applies clamping force to the right end of the workpiece through the screw 5, the clamping plate 6 and the nut 7, while the limiting mechanism drives the eccentric wheel 10 to rotate and abut against the left end face of the workpiece through the transmission of the worm gear 12, the worm 13 and the eccentric wheel 10, forming a left-side limit on the workpiece.
