Description

Technical Field

[0001] The utility model belongs to the technical field of parts detection equipment, and more specifically relates to a detection jig for complex structural parts. Background Art

[0002] In the production process of 3C consumer electronic products, product size detection is one of the essential process flows.

[0003] like Figure 1 The traditional inspection method for the parts shown is to use altimeters, calipers, 2.5D measuring tools, etc. to detect defects such as distortion, deformation, and dimensional deviation of the parts. Inspection fixtures are used to help control the position or movement, or both, of the parts, thereby improving inspection accuracy. Therefore, dimensional inspection fixtures are indispensable auxiliary tools in product inspection.

[0004] However, traditional dimensional inspection jigs often only simply fix the product and can only inspect a single surface or feature, and are unable to inspect the dimensions of more complex structural parts. When other features or planes need to be inspected, the operator needs to reposition the product on another inspection jig, or multiple operators need to perform inspections simultaneously. Obviously, this inspection method is labor-intensive, inefficient, and increases labor costs and jig equipment costs. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a detection fixture for complex structural parts, which improves the detection efficiency and can be performed by a single person, reducing labor costs.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a detection jig for complex structural parts, characterized in that: it includes a base, a contour positioning block is provided on the base, a contour positioning groove is provided on the contour positioning block, a first support block is provided on one side of the contour positioning block, and a second support block is provided on the other side of the contour positioning block, a first detection block and a second detection block are slidably connected to the first support block, and the sliding direction is toward the contour positioning block, the first detection block is located above the second detection block, the ends of the first detection block and the second detection block close to the contour positioning block both pass through the first support block, and a detection area is formed between the two ends, a pre-pressing block is hinged on the second support block, the pre-pressing block rotates and presses on the part, and a quick pressing device is provided on the base, which applies a pressing force to the pre-pressing block.

[0007] Furthermore, a positioning pin is provided in the contoured positioning groove.

[0008] Furthermore, a limit pin is provided on the first supporting block, and waist-shaped limit grooves are provided on the first detecting block and the second detecting block, and the limit pin passes through the two waist-shaped limit grooves.

[0009] Furthermore, the pre-pressing block is provided with a contoured pre-pressing end corresponding to the contoured positioning groove.

[0010] Furthermore, arc-shaped grooves are provided on both sides of the ends of the first detection block and the second detection block away from the contour positioning block.

[0011] Furthermore, the quick pressing device is located on a side of the second supporting block away from the contoured positioning block.

[0012] Compared with the prior art, the beneficial effect of the present invention is that when inspecting parts, the parts are placed in the profiling positioning groove of the profiling positioning block, and then the pre-pressing block is rotated to lightly press the parts in the profiling positioning groove, and then pressure is applied to the pre-pressing block by the quick pressing device to make the pre-pressing block press the parts tightly, and then the first inspection block and the second inspection block on the first support block are moved toward the profiling positioning block, so that the end of the part extending out of the profiling positioning groove is located in the inspection area, and the size of the part can be quickly inspected by the first inspection block and the second inspection block, thereby improving the inspection efficiency. At the same time, a single person can perform the inspection operation, reducing labor costs. BRIEF DESCRIPTION OF THE DRAWINGS
