And the to-be-milled surface one 701 and the to-be-milled surface two 702 of the left workpiece 7 are installed horizontally upward, and the to-be-milled surface three 703 and the to-be-milled surface four 704 of the right workpiece 7 are installed horizontally upward.

[0043] Both ends of the first positioning rod 5 are respectively fixedly connected to the first vertical plate 201 and the second vertical plate 301. There are 5 first positioning rods 5, and all 5 first positioning rods 5 are perpendicular to the first vertical plate 201. Among them, 2 first positioning rods 5 are arranged at the lower left end of the left workpiece 7 and are used to position the two right-angle sides at the lower left end of the to-be-milled surface four 704 of the left workpiece 7. 2 first positioning rods 5 are arranged side by side and at intervals in the middle of the first vertical plate 201.

[0048] The positions of the three equal-height columns 202 correspond one-to-one and coaxially with the positions of the three guide pressure rods 306 on the corresponding side, making the positioning and pressing of the workpiece 7 more stable.

[0049] Preferably, as Figure 1 、 6 shown, the support assembly 4 includes a fixed plate 401 and a support screw 402. The front and rear ends of the right side surface of the fixed plate 401 are respectively fixedly connected to the left side surfaces of the second vertical plate 301 and the first vertical plate 201.

[0051] Preferably, as Figure 3 、 4 shown, both ends of the first positioning rod 5 are provided with first steps with a smaller outer diameter. The first vertical plate 201 is provided with first mounting holes 2011 that match the outer diameter of the first steps, and the second vertical plate 301 is provided with second mounting holes 3011 that match the outer diameter of the first steps.

The left workpieces 7 are horizontally installed with the first milling surface 701 and the second milling surface 702 facing upwards, and the right workpieces 7 are horizontally installed with the third milling surface 703 and the fourth milling surface 704 facing upwards. During work, with one-time clamping, the first milling surface 701 and the second milling surface 702 of the 10 left workpieces 7 can be milled simultaneously, and the third milling surface 703 and the fourth milling surface 704 of the 10 right workpieces 7 can be milled. After milling, the 10 left workpieces 7 and the 10 right workpieces 7 are exchanged and installed, and then the other two milling surfaces of the workpieces 7 can be completed, that is, only two clamps are required to complete the processing of the four milling surfaces of 20 workpieces 7.

[0054] The existing tooling can only complete the processing of the first milling surface 701 and the second milling surface 702 of 20 workpieces 7 with secondary clamping. The processing of the third milling surface 703 and the fourth milling surface 704 still requires additional tooling for processing. Compared with the existing tooling, this patent greatly improves the production efficiency and milling quality, and saves labor costs and the cost of another set of tooling.

[0055] The second embodiment of the present utility model is basically the same as the first embodiment, except that: on the bottom plate 1, two first adjustable supports 8, second adjustable supports 9, third adjustable supports 10, third adjustable supports 10, and fourth adjustable supports 11 that are symmetrically arranged front and back are respectively provided at positions corresponding to the 5 first positioning rods 5 from left to right, for supporting the first positioning rod 5 to prevent the first positioning rod 5 from deforming and extending the service life of the first positioning rod 5.

[0057] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
