[0024] See also Figure 1-4 A quick clamping jig specially used for milling machines for aviation parts includes a workbench 1 and a workpiece body 5. A mounting plate 2 is installed on the workbench 1, and a number of jig bodies 3 are arranged on the mounting plate 2. The workpiece body 5 is assembled on the jig body 3. Two docking columns 17 are provided on the jig body 3. A circular pressure plate 6 is connected to the docking column 17 by a screw 7. The bottom of the circular pressure plate 6 abuts against the top of the workpiece body 5. A number of positioning columns 9 are arranged on the jig body 3. The positioning columns 9 are adapted to the through holes 8 on the workpiece body 5. Handles 4 are connected to both sides of the workbench 1.

[0025] By cooperating with each other in structures such as the jig body 3 and the circular pressure plate 6, the mounting plate 2 at the bottom of the jig body 3 can be fixed on the machine tool workbench 1 during use, and then several workpiece bodies 5 can be loaded onto the jig. The workpiece can be accurately positioned by the positioning column 9, and the circular pressure plate 6 can be fixed to the jig through the hollow part on the workpiece body 5 by screws 7. The workpiece is pressed tightly by the circular pressure plate 6 so that the bottom plane of the workpiece is close to the jig plane, thereby achieving the purpose of firmly fixing the workpiece body 5 on the jig through the jig and the circular pressure plate 6, thereby completing the clamping process. If the workpiece is reversed, it cannot be loaded, avoiding assembly errors by operators, reducing errors caused by human factors, alleviating the workload of workers, and ensuring stable production quality.

[0026] Specifically, in this embodiment, a transmission cavity 11 is provided in the mounting plate 2, and a bidirectional threaded rod 12 is rotatably installed in the transmission cavity 11. Two mutually symmetrical transmission sliders 14 are threadedly connected to the bidirectional threaded rod 12.

Locking holes 15 are provided on the two transmission sliders 14, and the locking holes 15 are adapted to the protrusions on the connecting blocks 13. Two mutually symmetrical rectangular sliding holes 16 are provided on the bottom inner wall of the transmission cavity 11. The two rectangular sliding holes 16 are both connected to the outside world, and the two transmission sliders 14 slide in the two rectangular sliding holes 16 respectively.

[0027] By cooperating with the provided bidirectional threaded rod 12, the transmission slider 14 and the connecting block 13, when connecting the mounting plate 2 to the workbench 1, the two rectangular sliding holes 16 at the bottom of the mounting plate 2 are aligned with the workbench 1 and inserted to achieve preliminary limiting of the mounting plate 2. At this time, the bidirectional threaded rod 12 is rotated to drive the two transmission sliders 14 to approach each other and clamp the two connecting blocks 13. When the transmission slider 14 contacts the connecting block 13, the locking hole 15 on the transmission slider 14 is sleeved on the protrusion on the connecting block 13, thereby achieving locking and fixing between the transmission slider 14 and the connecting block 13, thereby completing the connection and fixing process between the mounting plate 2 and the workbench 1.

[0028] Specifically, in this embodiment, the bidirectional threaded rod 12 passes through the transmission cavity 11 and extends to the outside where an adjustment block 10 is provided at one end thereof. The adjustment block 10 is provided with an inner hexagonal groove at one end thereof close to the outside.

[0029] By providing the adjustment block 10 and the inner hexagonal groove, an outer hexagonal wrench can be inserted into the inner hexagonal groove in the adjustment block 10 to drive the adjustment block 10 to rotate, thereby facilitating the rotation of the bidirectional threaded rod 12.
