[0028] Embodiment

[0029] Referring to Figure 1 , 2 shown, in an embodiment of the present utility model, a fixture for special-shaped parts includes

[0030] A bottom plate 1, which is set to a square structure and made of aluminum alloy material;

[0031] The first vertical plate 2 is vertically and fixedly connected to the bottom plate 1 and is made of aluminum alloy. The upper part of the first vertical plate 2 is provided with a first clamping surface 235, and the first clamping surface 235 matches the special-shaped contour at the reinforcing rib of the special-shaped part. Further, the first clamping surface 235 is a convex structure;

[0032] The second vertical plate 3 is detachably and vertically connected to the bottom plate 1 and is made of aluminum alloy. The second vertical plate 3 is arranged opposite to the first vertical plate 2, and the first vertical plate 2 and the second vertical plate 3 have the same height. The upper part of the second vertical plate 3 is provided with a second clamping surface 314, and the second clamping surface 314 matches the special-shaped contour at the reinforcing rib of the special-shaped part. Further, the second clamping surface 314 is a concave structure. The second clamping surface 314 is arranged horizontally opposite to the first clamping surface 235 and the two are profile-matched. The first vertical plate 2 and the second vertical plate 3 are connected by bolts 4. When clamping the special-shaped part, after aligning the first vertical plate 2 with the second vertical plate 3, tighten the bolts 4 so that the first clamping surface 235 and the second clamping surface 314 approach each other and clamp the reinforcing rib of the part from both sides. Clamping the reinforcing rib of the part by the first clamping surface 235 and the second clamping surface 314 can prevent the part from deforming due to the acting force of the fixture.

[0033] In an embodiment of the present invention, referring to Figure 2 As shown, on the side of the first vertical plate 2 close to the second vertical plate 3, a first clamping portion 23 protrudes, and the first clamping portion 23 is provided with the first clamping surface 235. On the side of the second vertical plate 3 close to the first vertical plate 2, a second clamping portion 31 protrudes, and the second clamping portion 31 is provided with the second clamping surface 314. When the fixture clamps the part, the first clamping portion 23 and the second clamping portion 31 are inserted into the concave portion formed by multiple reinforcing ribs of the part or pressed downward on the reinforcing rib.

[0034] In an embodiment of the present invention, referring to Figure 4 As shown, limiting grooves 232 are arranged along the bottom surface and the top surface of the first clamping portion 23, and the limiting grooves 232 extend toward the side where the second clamping portion 31 is provided. When the second vertical plate 3 pushes the special-shaped part, the rib columns on the reinforcing rib of the special-shaped part horizontally slide into the limiting grooves 232 and are limited by the limiting grooves 232 to prevent the part from loosening.

[0035] In an embodiment of the present invention, referring to Figure 4 and 6 As shown, the top surface of the first clamping portion 23 is provided with a first inclined surface 233, and the top surface of the second clamping portion 31 is provided with a second inclined surface 311. The first inclined surface 233 and the second inclined surface 311 are inclined in the same direction, and the limiting groove 232 is located on the first inclined surface 233.

[0036] In an embodiment of the present utility model, referring to Figure 4 as shown, the first clamping portion 23 is provided with a first avoidance opening 234, and the first avoidance opening 234 is inclined in a direction different from that of the first inclined surface 233. The first avoidance opening 234 is used to avoid the reinforcing rib of the part, so that the first clamping curved surface 235 fully contacts the part.

[0037] In an embodiment of the present utility model, referring to Figure 6 as shown, the bottom surface of the second clamping portion 31 is provided with a curved surface 312, and one end of the curved surface 312 is provided with a concave portion 313.

[0038] In an embodiment of the present utility model, referring to Figure 3 as shown, the lower part of the first vertical plate 2 is fixedly connected to the base 21, and the first vertical plate 2 is perpendicular to the base 21. The base 21 is provided with a plurality of through holes 212, and the bottom plate 1 is provided with screw holes corresponding to the through holes 212. Bolts pass through the through holes 212 and are threadedly connected to the screw holes, so that the base 21 can be detachably fixedly connected to the bottom plate 1. Further, the base 21 and the first vertical plate 2 are integrally formed to ensure that the first vertical plate 2 is vertically installed on the bottom plate 1.

[0039] In an embodiment of the present utility model, referring to Figure 3 as shown, the base 21 is provided with a second avoidance opening 211, and the second avoidance opening 211 is in imitation matching with the second vertical plate 3. When the first clamping curved surface 235 and the second clamping curved surface 314 clamp the part, the lower part of the second vertical plate 3 is located in the second avoidance opening 211. The second avoidance opening 211 can limit the width direction of the second vertical plate 3 to ensure that the first clamping curved surface 235 is aligned with the second clamping curved surface 314. Further, the second avoidance opening 211 is square.

[0040] In an embodiment of the present utility model, referring to Figure 3 as shown, a connecting portion 22 is convexly provided on one side of the first vertical plate 2 close to the second vertical plate 3. Specifically, the connecting portion 22 is provided at a position slightly above the middle of the first vertical plate 2. The distance from the connecting portion 22 to the first clamping portion 23 is less than its distance to the base 21. The connecting portion 22 is provided with a screw hole, and the second vertical plate 3 is provided with a through hole 32 opposite to the connecting portion 22. The bolt 4 passes through the through hole 32 and is threadedly connected to the connecting portion 22 to realize the fixed connection between the first vertical plate 2 and the second vertical plate 3.

[0041] In an embodiment of the present utility model, referring to Figure 3 as shown, a smooth bending avoidance portion 231 is provided at the edge of the first clamping curved surface 235, which is used to prevent the first clamping portion 23 from scratching the part.

[0042] The working principle of the special-shaped part fixture described in this utility model is as follows:

[0043] During clamping, after the rib of the special-shaped part is close to the first clamping surface 235, the lower part of the second vertical plate 3 is placed into the second avoidance opening 211, and it is ensured that the second clamping surface 314 of the second vertical plate 3 faces the first clamping surface 235. Then, the bolt 4 is tightened to make the second vertical plate 3 close to the first vertical plate 2. The first clamping surface 235 and the second clamping surface 314 approach each other and finally clamp the rib of the special-shaped part from both sides, realizing the positioning and clamping of the special-shaped part. Then, the bottom plate 1 of the fixture is placed on the prefabricated bottom plate 1 of the detection device. After ensuring that the part is parallel to the detection device, the detection is carried out. After the detection is completed, the bolt 4 is loosened, the second vertical plate 3 is removed, and then the part is removed.

[0044] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of this utility model creation.
