as shown in fig. 1-3, the utility model provides a mat cover milling groove drilling and fixing device, which comprises a plate-shaped clamp body 2; the middle part of the plate surface of the plate-shaped clamp body 2 is provided with a positioning block 10, the left side and the right side of the positioning block 10 are respectively provided with a multi-station positioning special-shaped groove, the left side and the right side of the plate-shaped clamp body 2 corresponding to the special-shaped grooves are respectively provided with a pressing plate, and one side of the pressing plate, which is close to the positioning block 10, is provided with a movable pressing plate 7. The multi-station positioning special-shaped grooves are symmetrically arranged on the left side and the right side of the positioning block 10. Two positioning special-shaped grooves are respectively arranged on two sides of the positioning block 10. Each movable pressing plate 7 is provided with two abutting pins which are respectively abutted against the edge of one pad cover, a first rotating pin 6 perpendicular to the plate surface of the plate-shaped clamp body is arranged on the movable pressing plate 7 between the two abutting pins in a penetrating mode, and the first rotating pin 6 is fixedly arranged on the pressing plate. The positioning special-shaped groove is provided with a U-shaped surface for abutting against the edge of the cushion cover 12. A second rotating pin 8 is arranged between one end of the pressing plate and the plate surface of the plate-shaped clamp body 2, and the second rotating pin 8 is arranged at the end part of the same side of the two pressing plates. The plate-shaped clamp body 2 also comprises a pressing rod 3 and a locking nut 5; a compression rod 3 for tensioning the compression plates at two sides is arranged between the end parts of the other sides of the two compression plates, and a lock nut 5 is sleeved on the compression rod 3. The processing fixing device also comprises a bottom plate 1. The plate-shaped clamp body 2 also comprises a supporting pin 9 and a cushion cover 12 which are used for supporting the workpiece and protrude out of the plate surface of the plate-shaped clamp body.
