[0004] To achieve the above object, the utility model adopts the following technical scheme:

[0005] A kind of thin plate lug sealing groove turning processing clamping tool, including base, pressing plate, pressing ring, the end face of the base is attached with part, and the base is equipped with the boss structure for fixing lug;The pressing plate, pressing ring are respectively pressed on the inside and outside two parts in part lug non-processing area, and pressing ring is also used to be fixed to lug, and pressing plate, pressing ring are all fixed between part and base by fixed nut.

[0006] Specifically, the pressing plate is horseshoe ring, and the bottom is provided with a groove matched with the lug. It is pressed on the upper end of the part, and the bottom surface is provided with a groove matched with the lug to be machined. The opening position can avoid the reinforcing rib of the lug, and the other positions are attached with the part.

[0007] Specifically, the inner diameter of the pressing plate is greater than the large diameter of the part to be machined. Ensure that the machining area is exposed.

[0008] Specifically, the base is cylindrical.

[0009] Specifically, it further includes a pressing ring, the outer diameter of the pressing ring is less than the small diameter of the part to be machined, to ensure that the machining area is exposed, and the pressing ring is detachably connected with the lug.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] (1) This utility model is applied to the turning of the sealing groove of the ear hole of thin plate. The tooling base is directly aligned, and the thin plate can be directly machined after being fixed on the tooling. The subsequent parts of this machined part do not need to be re-aligned and tool-set again, which reduces the number of tool-set times and tool-set time in batch processing, improves efficiency, reduces labor intensity, and improves processing quality and efficiency.

[0012] (2) This utility model can be extended to the machining of thin plate support parts with two or more support ears. For different inner and outer diameters of support ears, the pressure plate and pressure ring of the matching size can be replaced. For support ears with different center distances, the position of the two protrusions of the base can be adjusted. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Example:

[0021] like Figures 1 to 5 As shown, this embodiment provides a machining fixture for the sealing groove of a thin plate support, including a base. The main body of the base fixture is cylindrical and used for lathe clamping. Its end face fits against the thin plate to ensure the flatness of the part. The base has two bosses that mate with the holes of the support to fix the support and ensure the relative position to prevent the part from rotating.

[0022] In the embodiment, the base is provided with a pressing plate, the pressing plate is a horseshoe shape, the pressing plate is pressed on the upper end of the part, the bottom surface is provided with a groove matched with the lug of the part to be machined, the pressing plate is further provided with an opening, the lug reinforcing rib can be avoided, other positions are matched with the part to ensure uniform stress, the inner diameter of the pressing plate should be greater than the large diameter of the to-be-machined area to ensure that the to-be-machined area is exposed.

[0023] In the embodiment, the part needs to be machined, and a pressing ring is used to fix the lug, the outer diameter of the pressing ring should be smaller than the small diameter of the to-be-machined area to ensure that the to-be-machined area is exposed.
