[0018] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0019] The present invention is further described in detail below with reference to the accompanying drawings and embodiments: like Figure 3As shown, a fixture for milling and drilling of an intake cross-tube comprises a base plate 1 that can be fixedly mounted on a workbench, and a vertical plate 2 vertically arranged on the base plate 1; a vertical pressing mechanism 12 is arranged at the front end of the left side of the base plate 1; a left support 10 and a right support 9 for supporting the air inlet of the intake cross-tube are arranged on the right side of the vertical pressing mechanism 12; a middle support 11 for supporting the bottom of the intake cross-tube is arranged on the inner side of the left support 10; a positioning block 6 is arranged on the right side of the vertical plate 2, and a V-shaped block 5 is arranged on the left side of the positioning block 6; a right-side pressing mechanism 7 is arranged at the upper end of the V-shaped block 5; a right-side supporting nail 8 is arranged on the left side of the V-shaped block 5, a left-side pressing mechanism 13 is arranged at the upper left end of the right-side supporting nail 8, and a left-side pressing mechanism 13 is arranged at the lower left end of the left-side pressing mechanism 13.

[0020] Further, such as Figure 3-7 As shown, a plurality of lifting rings 3 are arranged at the top of the vertical plate 2, and a rib plate 4 is arranged between the back side of the vertical plate 2 and the bottom plate 1.

[0021] Further, such as Figure 3-7 As shown, two lifting rings 3 are provided, which are respectively provided at the two ends of the top of the vertical plate 2 .

[0022] Further, such as Figure 3-7 As shown, two ribs 4 are provided, which are respectively provided at two ends of the back side of the vertical plate 2 .

[0023] Further, such as Figure 3-7 As shown, the vertical pressing mechanism 12 includes a first support rod 121 vertically arranged on the base plate 1, a first stud 122 arranged on the right side of the first support rod 121, and a first pressure plate 123 arranged at the top of the first support rod 121 and the first stud 122; a first spring 124 is sleeved on the outer side of the first stud 122; a first rectangular through hole is arranged in the middle position of the first pressure plate 123; a first clamping groove for inserting the end of the first support rod 121 is arranged at the bottom left side of the first pressure plate 123; the end of the first support rod 121 is inserted in the first clamping groove of the first pressure plate 123; the first stud 122 is inserted in the first rectangular through hole, and a first conical washer and a first spherical washer are arranged between the top nut of the first stud 122 and the upper surface of the first pressure plate 123.

[0024] Specifically, the first slot at the bottom of the first pressure plate 123 and the first rectangular through hole in the middle position enable the first pressure plate 123 to be adjusted left and right, which is convenient for installation and disassembly. The installation position of the vertical pressure mechanism 12 and the installation position of the left support 10 and the right support 9 need to ensure that after the cast blank of the intake cross pipe for processing the intake flange surface is fixed to the fixture, the position of the flange surface does not affect the cutting during milling and drilling. The first spring 124 is actually a whole spring that is set on the outside of the first stud 122 (only a section is drawn in the figure). It is to support the first pressure plate 123 from drooping when the first stud 122 is not tightened. The first conical washer and the first spherical washer are set to ensure the compression of the first pressure plate 123, so that the first pressure plate 123 can better clamp the upper end of the flange surface when the first stud 122 is tightened.

[0025] Further, such as Figure 3-7 As shown, the right-side pressing mechanism 7 and the left-side pressing mechanism 13 have the same structure, both of which include a second support rod 131 vertically arranged on the vertical plate 2, a second stud 132 arranged at the lower end of the second support rod 131, and a second pressing plate 133 arranged at the top of the second support rod 131 and the second stud 132; a second spring 134 is sleeved on the outer side of the second stud 132; a second rectangular through hole is arranged in the middle position of the second pressing plate 133; a second clamping groove for inserting the end of the second support rod 131 is arranged at the bottom of the upper end of the second pressing plate 133; the second support rod 131 is inserted in the second clamping groove of the second pressing plate 133; the second stud 132 is inserted in the second rectangular through hole; a second conical washer and a second spherical washer are arranged between the top nut of the second stud 132 and the upper surface of the second pressing plate 133.

[0026] Specifically, the second support rod 131, the second stud 132, the second pressure plate 133 and the second spring 134 have the same structure and function as the first support rod 121, the first stud 122, the first pressure plate 123 and the first spring 124 in the vertical pressure structure, but the installation position is different, which will not be repeated.

[0027] Further, such as Figure 3-7 As shown, a medium-sized tooth surface support nail is arranged at the top of the middle support 11. The medium-sized tooth surface support nail is arranged to facilitate the adjustment of the support height and ensure the stability of the support.

[0028] Further, such as Figure 3-7 As shown, cylindrical head screws are provided at the tops of the right support 9 and the left support 10. The cylindrical head screws are provided to facilitate the adjustment of the support height.

[0029] Further, such as Figure 3-7As shown, two U-shaped holes are arranged on the left and right sides of the bottom plate 1, and the U-shaped holes are fixed by hexagon socket head screws 15; a plurality of bolt through holes are arranged in the middle of the bottom plate 1. The U-shaped holes and the bolt through holes are arranged to facilitate fixing the bottom plate 1 on the workbench of the machining center.

[0030] Further, such as Figure 3-7 As shown, a flat key 16 is also provided at the middle of the bottom of the base plate 1 for easy positioning.

[0031] When it is inconvenient to fix the workbench of the machining center with the hexagon socket head screws 15, an external fixing device can also be used to fix the base plate on the workbench of the machining center.

[0032] Directions: like Figure 7 As shown in the figure, the cast blank of the intake cross-through pipe to be processed with the intake flange surface is mounted on the fixture, and the shape of the cast blank of the intake cross-through pipe is positioned by the "six points" such as the V-block 5 clamping the end of the pipe (3-point positioning), the positioning block 6 supporting the top of the pipe, the middle support 11 supporting the bottom of the pipe upward, and the right support 9 supporting the flange surface of the pipe upward. Then, the right side pressing mechanism 7, the left side pressing mechanism 13 and the vertical pressing mechanism 12 are used to press the cast blank of the intake cross-through pipe, and by setting the left side pressing mechanism 13 and the vertical pressing mechanism 12, the left side pressing mechanism 13 and the vertical pressing mechanism 12 are used to press the cast blank of the intake cross-through pipe. Multiple "floating supports" such as support 10, right support nail 8 and left support nail 14 are used to ensure the clamping rigidity of the cast blank of the intake cross-tube. After the cast blank of the intake cross-tube is fixed on the fixture, the fixture is hoisted to the workbench of the machining center through the lifting ring 3 and fixed. The flange surface of the cast blank of the intake cross-tube to be processed is milled and drilled. By using this fixture, the first step does not need to rely on marking and can be processed on the machining center.
