[0018] The present invention will be described in detail with reference to the accompanying drawings.
[0019] like Figures 1-5 As shown, the inspection fixture for wire retaining rings for holes includes an inspection base plate 1, a pressure plate 2, a locking structure, and an inspection gauge 6.
[0020] The detection base plate 1 has a shallow circular groove on its upper surface, the inner diameter of which matches the outer diameter of the wire retaining ring 7 for the hole. A deep partition groove 9 is provided on one side of the edge of the shallow circular groove. The pressure plate 2 is circular, with its outer diameter smaller than the inner diameter of the shallow circular groove. The bottom edge of the pressure plate 2 has a chamfer for pressing the wire retaining ring 7. In this embodiment, the chamfer angle is 60 degrees. The outer edge of the pressure plate 2 has a detection clearance groove 10 corresponding to the deep partition groove 9. The width of the deep partition groove 9 is greater than the distance between its opening and the wire retaining ring 7, and the width of the detection clearance groove 10 is greater than the width of the deep partition groove 9. The detection gauge 6 is rod-shaped, and its end is used to insert into the detection clearance groove and the deep partition groove.
[0021] The locking structure connects the pressure plate 2 and the detection base plate 1. In this embodiment, the locking structure includes multiple locking bolts 4. The detection base plate 1 has through holes corresponding to the locking bolts 4, and the lower surface of the detection base plate 1 has locking nuts 8 corresponding to the through holes. The pressure plate 2 has screw holes corresponding to the locking bolts 4. The tip of the locking bolt 4 passes through the through hole of the detection base plate 1 and is connected and fixed to the locking nut 8. Under normal conditions, the detection base plate 1 and the locking nut 4 are not separated, and the pressure plate 2 and the locking bolt 4 are not separated, facilitating assembly.
[0022] The pressure plate 2 and the detection base plate 1 are respectively provided with weight reduction holes 3 at their centers and on their surfaces. The upper surface of the pressure plate 2 is provided with a handle 5 for easy movement.
[0023] Working principle:
[0024] 1. When using, place the wire retaining ring 7 of the hole to be tested into the circular shallow groove of the test base plate 1. The outer circumferential surface of the wire retaining ring 7 is in contact with the inner wall of the circular shallow groove, and the open end of the wire retaining ring 7 is facing the partition deep groove 9 at the edge of the circular shallow groove. The open end of the wire retaining ring 7 is located above the partition deep groove 9.
[0025] 2. Holding handle 5, place pressure plate 2 into the shallow circular groove of the detection base plate 1. At this time, the annular chamfered surface of the bottom edge of pressure plate 2 presses against the wire retaining ring 7 for the hole. (See below) Figure 5 This enables radial and vertical positioning of the wire retaining ring 7 for the hole, preventing displacement during measurement and ensuring detection accuracy.
[0026] 3. Hold the test gauge 6 and insert its end into the test clearance groove 10 of the pressure plate 2. If it can pass smoothly through the open end of the wire retaining ring 7 and enter the partition groove 9, the product is qualified; otherwise, it is unqualified.
[0027] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
