[0008] The upper clamp is used to clamp the workpiece, and a rectangular slot is provided on the upper clamp corresponding to the placement slot.

[0009] Both the upper and lower clamps have a first threaded hole on their sides. The first threaded hole is used to assemble a rotating mechanism, which is used to flip the upper clamp.

[0010] A clamping handle is installed on the upper surface of the lower clamp and positioned on the opposite side of the rotating mechanism. The clamping handle is used to clamp the upper clamp and the lower clamp.

[0011] The workpiece has a light-blocking groove horizontally opened on the bottom surface of its inner cavity, and a strip-shaped protrusion integrally formed on its lower surface.

[0012] As a preferred embodiment of this utility model, the lower clamp is provided with symmetrical second threaded holes, and the fixed base plate is provided with countersunk connecting holes corresponding to the second threaded holes. Countersunk bolts are installed in the countersunk connecting holes and the second threaded holes.

[0014] As a preferred embodiment of this utility model, the placement slots on the lower clamp are arranged in two rows, with three slots evenly spaced in each row.

[0015] As a preferred embodiment of this utility model, the clamping handles are arranged side by side in two.

[0016] In a preferred embodiment of this utility model, the rotating mechanism is a hinge, with two hinges symmetrically arranged and fixed by screws to the first threaded hole.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects:

[0018] This invention enables accurate workpiece positioning by setting placement slots corresponding to the workpiece contour and corresponding strip grooves for the strip protrusions, thereby improving the positioning accuracy of the workpiece and ensuring the precision of the milling process.

[0028] Lower clamp 2: Used to place workpiece 7. Lower clamp 2 is mounted on fixed base plate 1. Lower clamp 2 has a placement groove 8, the shape of which corresponds to the outline of workpiece 7. Workpiece 7 is placed in the placement groove 8, which can accurately position workpiece 7. Lower clamp 2 has symmetrical second threaded holes 10. Fixed base plate 1 has countersunk connecting holes 11 corresponding to the second threaded holes 10. Countersunk bolts are installed in the countersunk connecting holes 11 and the second threaded holes 10, and the lower clamp 2 is firmly mounted on fixed base plate 1 by countersunk bolts. The bottom surface of the placement groove 8 has a strip groove 9 corresponding to the strip protrusion 13 on the bottom surface of workpiece 7, which further improves the stability and positioning accuracy of workpiece 7. The placement groove 8 on lower clamp 2 is set in two rows, with three equidistant grooves in each row. This design can process multiple workpieces 7 at the same time, improving production efficiency.

[0029] Upper clamp 3: used to clamp workpiece 7. A rectangular slot 5 is provided on the upper clamp 3 corresponding to the placement slot 8.

[0031] Workpiece 7: A light-blocking groove 12 is horizontally opened on the bottom surface of its inner cavity, and a strip-shaped protrusion 13 is integrally formed on the bottom surface.

[0032] The working principle of this utility model is as follows: Open the upper clamp 3, flip the upper clamp 3 to a suitable position using the hinge, and place the workpiece 7 into the placement groove 8 of the lower clamp 2 in sequence, so that the strip-shaped protrusion 13 on the bottom surface of the workpiece 7 matches the strip-shaped groove 9 on the bottom surface of the placement groove 8, ensuring that the workpiece 7 is placed stably and accurately positioned. Flip the upper clamp 3 to a position that fits against the lower clamp 2 using the hinge, so that the rectangular groove 5 on the upper clamp 3 corresponds to the placement groove 8. Then, operate the clamping handle 6 to clamp the upper clamp 3 and the lower clamp 2, thereby firmly clamping the workpiece 7 in the placement groove 8. After the workpiece 7 is clamped, start the processing equipment to perform milling on the bottom surface of the inner cavity of the workpiece 7 to mill out the light-blocking groove 12.
