[0027] In summary, the slot milling machine of the utility model can automatically mill slots and can adapt to PC masks of different sizes and slot processing of different sizes, has good flexibility and a wide range of uses; the positioning of the jig and the product is simple and convenient, and the jig can be quickly disassembled and assembled and the product can be loaded and unloaded; two jigs are set, which can be loaded and processed alternately, and can realize the milling of multiple PC masks at the same time, thereby improving production efficiency and production quality.

[0028] Example 2

[0029] Based on the structure of Example 1, Figure 1 , 2 As shown in , 4, the fixture 2 includes a base plate 21, and the base plate 21 is provided with a plurality of slots 211 corresponding to the masks 11 and used for inserting the masks, and an upper pressing plate 22 covering the slot 211 and used for pressing the mask 11 is provided above each of the slots 211.

[0030] In the above structure, if Figure 4 As shown, the base plate 21 is provided with a stop top 212 at one end close to the positioning block 2 33, the slot 211 is a through slot, and a machined clearance groove is provided between the slot 211 and the stop top 212. The machined clearance groove exposes the position to be processed on the mask, and one end of the mask 11 is inserted into the slot 211 and is limited by the stop top 212.

[0031] In addition, the upper pressing plate 22 is elastically connected to the base plate 21 , and a spring connected to the base plate 21 is provided at a corner of the upper pressing plate 22 .

[0032] like Figure 1-4As shown, the fixture 2 cooperates with the positioning mechanism 24 to position the PC mask. Specifically, the positioning mechanism 24 includes an upper pressure cylinder 41 and a push-up cylinder 42. There are multiple upper pressure cylinders 41, which are arranged one-to-one with the upper pressure plate 22. A pressure block is provided at the output end of the upper pressure cylinder 41. The upper pressure cylinder 41 on each positioning mechanism 24 is fixed to the workbench 1 through a cylinder seat 1 43, and is located above the corresponding upper pressure plate 22. The push-up cylinder 42 is arranged at the end of the fixture 2 away from the milling cutter 5, and is used to push the mask on the fixture 2. A push plate is provided at the output end of the push-up cylinder 42, and the push-up cylinder 42 on each positioning mechanism 24 is fixed to the workbench 1 through a cylinder seat 2 44. The cylinder seat 2 44 is also slidably connected to the workbench 1 through a moving mechanism. By adjusting the position of the cylinder seat 2 44 on the workbench 1, it can be used to position PC masks with a larger length range.

[0033] In order to better control the working rhythm of the two fixtures 2, Figure 2 As shown, the second positioning mechanism 4 also includes a button switch 45 arranged on a cylinder seat 43 and corresponding to the fixture 2 one by one, and the button switch 45 is electrically connected to the upper pressing cylinder 41 and the push cylinder 42.

[0034] After the PC mask is inserted into the slot on the jig, press the button switch, the push cylinder starts to push the PC mask against the stop top, and then the upper pressure cylinder starts to drive the upper pressure plate to press down to completely position the PC mask in the slot, and then the milling process can begin. When the upper pressure plate 22 is not pressed by the lower pressure cylinder 41, the upper pressure plate 22 is separated from the top surface of the base plate 21 by a distance under the action of the spring, which can facilitate the insertion of the PC mask. In addition, the spring can also provide a buffer when the lower pressure cylinder 41 presses down, reducing the damage to the PC mask during the downward pressure.
