[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] Reference Figure 1-3 A lower die base processing fixture includes a base 5, an inverted T-block 10, and a clamp body 9. A support frame 8 is fixedly arranged at the bottom of the base 5, and an intermediate groove 6 is fixedly arranged at the middle position of the side of the support frame 8. Mounting holes 7 are opened at the four corners of the bottom of the support frame 8, and the entire lower die base processing fixture can be fixed on the machine tool by bolts.

[0022] An accommodating cavity 2 is provided on the left and right sides of the base 5, a T-slot 11 is provided on the top of the base 5, an inverted T-block 10 is movably inserted into the T-slot 11 along the horizontal direction, and a quick-fix component is provided on the base 5 to quickly fix the clamp body 9 on the top of the base 5, and the common shaft 3 and the intermediate gear 1 of the quick-fix component are installed inside the accommodating cavity 2.

[0023] The quick-fix assembly includes a blocking arc block 4, a common shaft 3, an intermediate gear 1, and an electric push rod 15. An accommodating cavity 2 is opened on the left and right sides of the base 5. Both ends of the common shaft 3 are rotatably connected to the accommodating cavity 2. Both ends of the common shaft 3 are fixedly provided with blocking arc blocks 4. The blocking arc block 4 has a water drop shape in appearance, and the end of the blocking arc block 4 plays a fixed limiting role for the inverted T block 10.

[0024] An intermediate gear 1 is fixedly set in the middle position of the common shaft 3, and a vertical gear rod 12 is stably meshed with the side surface of the intermediate gear 1 along the vertical direction. The bottoms of the two groups of vertical gear rods 12 are commonly fixed on the top of a common rod 13, and an auxiliary column 14 is symmetrically fixed on the bottom of the common rod 13. The auxiliary column 14 is movably inserted into the support frame 8, and the auxiliary column 14 assists the vertical gear rod 12 on the top of the common rod 13 to move stably in the vertical direction.
