[0002] For products with assembly requirements, they need to be detected after being processed and formed to ensure their normal assembly. Some shell-like parts use screws to cooperate with blind-hole threaded holes for assembly. For example Figure 1 The shown part includes a part main body. A circle of mounting frames is arranged at the bottom edge of the part main body. A positioning pin and a blind-hole threaded hole are arranged on the bottom surface of the mounting frame. After the part is processed and formed, the position degree of the threaded hole needs to be detected. Since the threaded hole is not through, it can only be detected from one side. When detecting the threaded hole of this kind of part, it needs to be positioned and fixed. If the mounting frame of the part is placed upward, the positioning is inconvenient; if the mounting frame of the part is placed downward, the threaded hole is downward, and the detection needs to be completed from the bottom, and the detection operation is inconvenient.

[0027] Both ends of the detection plate 2 are rotatably connected to the bracket 1 through shaft rods; a limiting component 6 is arranged between the detection plate 2 and the bracket 1, so that the detection plate 2 can only reciprocally rotate within a range of 180 degrees; on one side of the bracket 1, a three-in-one motor 7 for driving the detection plate 2 to reciprocally rotate within a range of 180 degrees is arranged, and a controller 8 electrically connected to the three-in-one motor 7 is fixedly arranged at the top end of the bracket 1.

[0028] In this embodiment, when detecting the position degree of the blind threaded hole 94 on the part 9, first place the part 9 on the detection plate 2, insert the positioning pin 3 into the positioning hole 93 of the part 9 to position the part 9, and then press and fix both sides of the part 9 through the vertical quick clamp 4; then control the three-in-one motor 7 by the controller 8 to drive the detection plate 2 to flip 180 degrees, place the part 9 below the detection plate 2, and make the opening of the threaded hole 94 face upward. At this time, make the threaded hole detection component 5 pass through the through hole 21 to detect the threaded hole 94.

[0029] The comprehensive inspection tool of the present application is convenient for positioning and fixing the part 9, accurate in detection, convenient in detection operation, high in detection efficiency, and suitable for batch detection of the part 9.

At this time, the threaded hole detection assembly 5 is placed above the detection plate 2. Then, the detection rod 53 is rotated by the driving rod 57.
