[0018] As Figures 1-4 shown, the utility model discloses a special-shaped product machining clamp, which comprises a base 1 and a clamp 2 arranged on the base, and further comprises an air cylinder 3, a pressing rod 31 is arranged on the telescopic rod of the air cylinder 3, the front end of the pressing rod 31 is pressed on both ends of the clamp 2, the clamp 2 comprises a tool base 21, a pressing plate 22 and a sliding block 23, a plurality of die cavities 24 for placing workpieces 4 are arranged in the length direction of the tool base 21, the die cavities 24 are arranged in two groups, a recess 25 is arranged between the opposite two die cavities 24, the sliding block 23 is placed in the recess 25, the pressing plate 22 is pressed on the surface of the die cavity 24, the sliding block 23 comprises side sliding blocks 231 on both sides and a side top sliding block 232 in the middle, the inner side of the side sliding block 231 is a slope, the outer side is a plane, and the inner side of the side sliding block 231 is in contact with the positioning surface of the innermost side of the workpiece 4, and the two sides of the side top sliding block 232 are both slopes and are adapted to the inner side of the side sliding block 231.

[0019] The utility model discloses a special -shaped product processing's clamp, mainly includes base 1, clamp 2, cylinder 3 and workpiece 4, base 1 is used for supporting clamp 2, clamp 2 is used for clamping workpiece 4, cylinder 3 is used for pressing tightly clamp 2, and it is convenient for workpiece 4 processing.

[0020] Specifically, the clamp 2 includes a tool base 21, a pressing plate 22, and a sliding block 23. The tool base 21 is provided with a plurality of mold cavities 24 for placing the workpiece 4. The mold cavities 24 are arranged in pairs, and a groove 25 is arranged between the two mold cavities 24. The sliding block 23 is placed in the groove 25. The side edge of the sliding block 23 is in contact with the side edge of the workpiece, so that the sliding block 23 positions the side edge of the workpiece 4. The upper part of the workpiece 4 is fixed and positioned by the pressing plate 22, which ensures the positioning effect of the clamp and improves the processing efficiency.

[0021] Further, the sliding block 23 includes two side sliding blocks 231 on the sides and a side top sliding block 232 in the middle. The inner side of the two side sliding blocks 231 is beveled, and the outer side is flat. The side top sliding block 232 is arranged between the two side sliding blocks 231, and its two sides are adapted to the bevels of the side sliding blocks 232.
