[0025] Due to the angle of the drawing, some components may not be drawn, but their positions and connection relationships can be partially understood based on the text expression.
[0026] like Figure 1-Figure 2 As shown, the utility model is a self-centering pneumatic tooling with block-like parts for auxiliary shock absorption, including a bottom plate 1, a positioning plate 16 is installed on the bottom plate 1, a vertical positioning block 14 is installed on the positioning plate 16, and a lateral positioning block 15 and a lateral cylinder 10 are respectively arranged on both sides of the vertical positioning block 14, the lateral positioning block 15 is installed on the positioning plate 16, and the lateral cylinder piston rod 11 faces the vertical positioning block 14 and is installed with a lateral top block 13. Self-centering mechanisms and clamping mechanisms are arranged on the other two sides of the vertical positioning block 14.
[0027] like Figure 3 As shown, the self-centering mechanism includes a sliding seat 7, which slides on the positioning plate 16, and the sliding seat 7 is connected to the transverse cylinder 10 through the transition plate 8. The transverse cylinder piston rod 11 passes through the sliding seat 7 and then connects to the transverse top block 13. A left clamping arm 26 and a right clamping arm 24 are provided on both sides of the sliding seat 7. The middle parts of the left clamping arm 26 and the right clamping arm 24 are rotatably mounted on the positioning plate 16 through the core shaft 25, and one end of the left clamping arm 26 and the right clamping arm 24 slides in the sliding seat 7.
[0028] like Figure 5As shown, a through hole is provided in the middle of the sliding seat 7 for the transverse cylinder piston rod 11 to pass through, and clamp arm grooves 7-1 are provided on both sides of the sliding seat 7 for the left clamp arm 26 and the right clamp arm 24 to slide.
[0029] In this embodiment, a hollow groove is provided in the middle of the block-like part, and the clamping mechanism includes a left-rotating angle clamping cylinder 19 and a right-rotating angle clamping cylinder 20. Figure 4 shown.
