[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] As shown in the figure, the pre-rotation lining iron tooling of this embodiment includes a support 2, a base plate 3, a milling surface clamping module and a milling edge clamping module; the base plate is arranged on the support.

[0019] The milling surface clamping module includes an A frame plate 4, an A hydraulic cylinder 5, an A wedge block 6, an A front slider 7, an A rear slider 8, a front positioning block 9 and a rear positioning block 10. The A frame plate is fixed on the bottom plate, and the A frame plate is provided with an I-shaped limiting groove 11 consisting of a front transverse limiting groove 111, a rear transverse limiting groove 112 and a vertical limiting groove 113. The A hydraulic cylinder is arranged on the bottom surface of the bottom plate, and the piston rod of the A hydraulic cylinder vertically passes through the bottom plate upward. The A wedge block is located in the middle of the vertical limiting groove, and the A wedge block is connected to the piston rod of the A hydraulic cylinder. The A front slider and the A rear slider are symmetrically arranged on the front and rear sides of the A wedge block, and the A front slider and the A rear slider are slidably matched with the vertical limiting groove. The A wedge block is slidably matched with the A front slider and the A rear slider through an inclined wedge surface; the front positioning block is arranged in the front transverse limiting groove, and the rear positioning block is arranged in the rear transverse limiting groove. The front positioning block and the rear positioning block are provided with a positioning groove 12 for positioning the pre-rotated lining iron.

[0020] The milling edge clamping module includes a B frame plate 13, a B hydraulic cylinder 14, a B wedge block 15, a B front slider 16 and a B rear slider 17. The B frame plate is arranged on the bottom plate, and a straight limit groove 18 and a pre-rotation lining iron positioning groove 19 are arranged on the B frame plate. The pre-rotation lining iron positioning groove is located at the front and rear ends of the straight limit groove. The B hydraulic cylinder is arranged on the bottom surface of the bottom plate, and the piston rod of the B hydraulic cylinder vertically passes through the bottom plate upward; the B wedge block is located in the middle of the straight limit groove, and the B wedge block is connected to the piston rod of the B hydraulic cylinder; the B front slider and the B rear slider are symmetrically arranged on the front and rear sides of the B wedge block, and the B front slider and the B rear slider are slidably matched with the straight limit groove, and the B wedge block is slidably matched with the B front slider and the B rear slider through the inclined wedge surface.

[0021] like Figure 2 As described above, the pre-rotated lining iron is placed in the corresponding positioning groove, and then the A hydraulic cylinder and the B hydraulic cylinder are controlled to drive the corresponding A wedge block and the B wedge block to move down respectively, and the A wedge block then pushes the A front slider and the A rear slider to clamp and fix the corresponding pre-rotated lining iron, and the B wedge block then pushes the B front slider and the B rear slider to clamp and fix the corresponding pre-rotated lining iron.
