The longitudinal moving mechanism includes a base frame, a moving frame, a first motor, a drive gear, and a longitudinal rack.

The fourth clamping arm mechanism (35) includes a fourth hydraulic cylinder (351), a fourth clamping arm (352), several fifth rollers (353), and several sixth rollers (354). One end of the fourth hydraulic cylinder (351) is hinged to the positioning frame (33), and the fourth clamping arm (352) is hinged to the positioning frame (33), thus making the fourth clamping arm reciprocate up and down. One end of the arm (352) is hinged to the other end of the fourth cylinder (351), allowing the other end of the fourth clamping arm (352) to reciprocate up and down under the drive of the fourth cylinder (351). Each fifth roller (353) is arranged side by side on the other end of the fourth clamping arm (352), and each sixth roller (354) is arranged side by side on the other end of the fourth clamping arm (352), with the sixth roller (354) and the fifth roller (353) arranged in an inverted V-shape. The arrangement also ensures that the sixth roller (354), the fifth roller (353), and the fourth roller (343) are aligned in the same direction. A second support groove (200) is formed between the sixth roller (354) and the fifth roller (353). The fourth roller (343) is located above the second support groove (200). The fourth roller (343), the fifth roller (353), and the sixth roller (354) together form a clamping gap (20).

7. The aluminum billet transfer gripper apparatus of claim 6 wherein: The positioning frame (33) has a storage cavity (331), and the third oil cylinder (341), the third clamping arm (342), the fourth oil cylinder (351) and the fourth clamping arm (352) are all located in the storage cavity (331), and the other end of the third clamping arm (342) and the other end of the fourth clamping arm (352) extend out of the storage cavity (331).

8. The aluminum billet transfer gripper device of claim 5 wherein: The moving drive mechanism (31) includes a drive motor (311), a drive gear (312), a drive rack (313), and at least two guide rails (314). Each guide rail (314) is mounted on the movable end of the transfer frame (1). The movable arm (32) is slidably fitted onto each guide rail (314). The drive rack (313) is mounted on the movable end of the transfer frame (1). The drive motor (311) is mounted on the movable arm (32). The drive gear (312) is mounted on the power output shaft of the drive motor (311) and meshes with the drive rack (313).

9. The aluminum billet transfer gripper apparatus of claim 1 wherein: The clamping point of the fixed clamping mechanism (2) is a horizontally penetrating clamping gap (10), and the lower wall of the clamping gap (10) forms a first support groove (100). The clamping point of the movable clamping mechanism (3) is a horizontally penetrating clamping gap (20), and the lower wall of the clamping gap (20) forms a second support groove (200), and the width of the second support groove (200) is smaller than the width of the first support groove (100).

10. The aluminum billet transfer gripper apparatus of claim 1 wherein: The transfer frame (1) includes a fixed frame (11), a movable frame (12), a drive motor (13), a drive gear (14), a drive rack (15), and at least two drive rails (16). Each drive rail (16) is arranged side by side on the fixed frame (11). The movable frame (12) is slidably fitted onto each drive rail (16). The drive rack (15) is arranged on the fixed frame (11). The drive motor (13) is arranged on the movable frame (12). The drive gear (14) is arranged on the power output shaft of the drive motor (13) and meshes with the drive rack (15). The fixed clamping mechanism (2) and the movable clamping mechanism (3) are both arranged on the movable frame (12).
