AI Technical Summary
The prior art has measurement errors and is less efficient when measuring the diameter of the center circle of the flange hole. In particular, manual use of calipers first measures the maximum or minimum distance between the two symmetrical holes, and then subtracts the diameter of the corresponding holes.
A connecting flange hole position detection tool is designed, including a fixing plate, a first threaded hole, a ring screw, a second threaded hole and a second screw. Through the combination of these components, the position and size of the flange hole can be quickly and accurately measured.
This inspection tool can reduce measurement steps, improve measurement efficiency, and reduce the error of human or caliper measurement through the measurement method of the hexagon screw.

[0021] Please refer to Figures 1-3 ,
[0022] Example 1: A connecting flange hole position detection tooling, including a fixing plate 1. The fixing plate 1 is in a "cross" shape. A first threaded hole 2 is opened at the middle position of the fixing plate 1. A lifting ring screw 3 is threadedly sleeved inside the first threaded hole 2. Four second threaded holes 4 are opened on the lower surface of the fixing plate 1. First screws 5 are threadedly sleeved inside the four second threaded holes 4 respectively. Four third threaded holes 6 are opened on the lower surface of the fixing plate 1. Second screws 7 are threadedly sleeved inside the four third threaded holes 6 respectively. The four second threaded holes 4 and the four third threaded holes 6 are respectively arranged in an array on the lower surfaces of the four ends of the fixing plate 1.
[0023] Example 2: The difference between this example and Example 1 is that, among them, the specification models of the four first screws 5 are all M5*10 hexagon socket head cap screws, which is convenient for detecting flanges of F07 model.
[0024] Example 3: The difference between this example and Example 1 is that, among them, the specification models of the four second screws 7 are all M6*10 hexagon socket head cap screws, which is convenient for detecting flanges of F10 model.
[0025] Example 4: The difference between this example and Example 1 is that, among them, the included angles between adjacent ends of the fixing plate 1 are all ninety degrees. The length between the opposite ends of the fixing plate 1 is 120 to 130 mm. The thickness of the fixing plate 1 is 15 mm to 20 mm. The width of each end of the fixing plate 1 is 18 mm to 22 mm. The size of the fixing plate 1 is restricted to facilitate the user to pick up and use, and it is convenient to operate.
[0026] Example 5: The difference between this example and Example 1 is that, among them, the lengths from the central positions of the four second threaded holes 4 and the four first screws 5 to the central position of the fixing plate 1 are both 35 mm. The positions of the four second threaded holes 4 and the four first screws 5 are restricted so that they can quickly detect flanges of F07 model.
[0027] Example 6: The difference between this example and Example 1 is that, among them, the lengths from the central positions of the four third threaded holes 6 and the four second screws 7 to the central position of the fixing plate 1 are both 51 mm. The positions of the four third threaded holes 6 and the four second screws 7 are restricted so that they can quickly detect flanges of F10 model.
[0028] In summary, when using the connecting flange hole position detection tooling, when measuring the holes of the F10 flange, first install the lifting eye screw 3 into the first threaded hole 2 on the fixed plate 1, then install the four second screws 7 into the four third threaded holes 6 on the fixed plate 1, and then fit the detection tooling to the upper surface of the flange so that the four second screws 7 coincide with the flange holes. If the bottom surface of the detection tooling is completely fitted to the upper surface of the flange, the center circle size of the flange holes is correct; otherwise, there is a machining error in the flange holes.
[0029] When measuring the holes of the F07 flange, first remove the second screws 7 from the fixed plate 1, then install the four first screws 5 onto the fixed plate 1, and then fit the fixed plate 1 to the surface of the flange. If the fixed plate 1 is completely fitted to the surface of the flange, the center circle size of the flange holes is correct; otherwise, there is a machining error in the flange holes.
[0030] When the tooling is not in use, install the first screws 5, the second screws 7, and the lifting eye screw 3 on the fixed plate at the same time to prevent subsequent loss of the screws and affect the use.
