The support member 4 is provided with a support surface 41 perpendicular to the first direction Y. The support surfaces 41 of the four support members 4 are all located on the same vertical plane. When the product is clamped along the first direction Y, each force-receiving point of the product is evenly stressed, preventing the product from bending and deforming. In this embodiment, the support member 4 is preferably set as a cylindrical structure, which is convenient for the support member 4 to be inserted into the groove on the back of the product;

[0033] Four quick clamps 2 are arranged on the vertical plate 3 on the same side as the support member 4. The quick clamps 2 are arranged in one-to-one correspondence with the support member 4, and the clamping members 21 of the quick clamps 2 are arranged facing the support surface 41 along the first direction Y to clamp the product along the first direction Y. Specifically, when the quick clamp 2 clamps the product along the first direction Y, the support member 4 supports the back of the product, and the first direction Y is the horizontal direction.

The square avoidance opening 5 is used to expose the back of the product so that the detection device can detect the back of the product. The second direction X is the horizontal direction.

[0035] In an embodiment of the present invention, referring to Figure 2 As shown, the vertical plate 3 is provided with three positioning blocks 7. The three positioning blocks 7 are arranged on the same side as the quick clamp 2. Among them, two positioning blocks 7 are arranged on the lower side of the square avoidance opening 5 along the third direction Z and have the same height to support and position the product from the bottom to ensure the parallelism of the product. The third direction Z is the vertical direction.

[0036] In an embodiment of the present invention, referring to Figure 2 As shown, one of the positioning blocks 7 is further arranged on one side of the square avoidance opening 5 along the second direction X to abut against the side of the product to ensure the perpendicularity of the product. The positioning block 7 can be arranged on the left or right side of the square avoidance opening 5.

[0037] In an embodiment of the present invention, referring to Figure 3 As shown, the positioning block 7 protrudes towards the square avoidance opening 5 with a positioning portion 71. The positioning portion 71 is arranged as a curved surface for contacting the product to prevent the positioning portion 71 from scratching the product. The positioning portion 71 protrudes to one end of the square avoidance opening 5 to limit the product within the projection area of the square avoidance opening 5 along the first direction Y, preventing the product from overlapping with the projection of the vertical plate 3 in the first direction Y.

[0038] In an embodiment of the present invention, referring to Figure 3 As shown, the positioning portion 71 extends along the second direction X so that the positioning portion 71 can match products of different sizes and improve the compatibility of the fixture.

[0040] In an embodiment of the present utility model, referring to Figure 1 as shown, it further includes two support blocks 6, and the two support blocks 6 are respectively arranged on both sides of the square avoidance opening 5 along the second direction X. The side surface of the support block 6 is fixedly connected to the vertical plate 3, and the bottom surface of the support block 6 is fixedly connected to the bottom plate 1. The two support blocks 6 are distributed on the same side or different sides of the vertical plate 3 along the first direction Y. When the two support blocks 6 are on the same side, the two support blocks 6 are also arranged on the same side as the four quick clamps 2.

[0041] In an embodiment of the present utility model, the positioning block 7 is made of stainless steel to ensure service life and positioning accuracy; the bottom plate 1, the vertical plate 3 and the support block 6 are all made of aluminum alloy, taking advantage of the physical properties of aluminum alloy such as good corrosion resistance, appropriate strength and light weight.

[0042] In an embodiment of the present utility model, referring to Figure 4 and 5 as shown, the support member 4 is provided with a connection seat 42 and a connection plate. Both the connection seat 42 and the connection plate are linearly distributed with a plurality of through holes. The vertical plate 3 is provided with an installation opening 31 matching the connection seat 42. The connection seat 42 is inserted into the installation opening 31 and fixedly connected to the connection plate through screws and nuts. The connection plate is also fixedly connected to the vertical plate 3 through screws and nuts.

[0043] The working principle of the measuring fixture of the present utility model is as follows:

[0044] First, place the bottom plate 1 horizontally, then put the product into the fixture from top to bottom. The bottom of the product is supported by the two positioning blocks 7 to achieve the third direction Z positioning. Then, push the product laterally so that the side of the product abuts against the positioning block 7 on the side of the fixture to achieve the second direction X positioning. Then, clamp the product through the four quick clamps 2 to achieve the first direction Y positioning. Then, the detection device starts to detect the size and shape of the product. After the detection is completed, unload the product, and then fix the next product on the fixture.
