Detailed Description
The invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, the invention comprises a handle 1 and a detection end which are fixedly connected, wherein the detection end comprises a detection conical surface 3 and a guide post 4 which are sequentially arranged, the detection conical surface 3 is positioned at one side close to the handle 1, the guide post 4 is positioned at one side far away from the handle 1, the large diameter end of the detection conical surface 3 is positioned at one side close to the handle 1, the detection conical surface 3, the guide post 4 and the handle 1 are arranged along the same central axis, the outer side wall of the detection end is provided with a slot as an observation port 6, the observation port 6 is arranged along the axis direction of the detection end, and the observation port 6 extends to at least the small diameter end of the detection conical surface 3 from the end face of the detection end, which is close to the handle 1 side.
Preferably, the detecting end further comprises an annular groove 5, and the annular groove 5 is arranged near the large-diameter end of the detecting conical surface 3 and is coaxially arranged with the detecting conical surface 3. The annular groove 5 is used for detecting whether the depth of the sealing conical surface meets the requirement.
For convenient processing, simultaneously convenient observation, the observation port 6 runs through the both ends of the detection end along the axis direction of the detection end.
For convenient observation, the observation port 6 is a V-shaped groove.
The tail of the guide post 4 is provided with a guide chamfer for facilitating the placement of the detection tool.
For convenient operation, a small diameter section 2 is arranged between the handle 1 and the detection end.
For convenient processing and assembly, the handle 1 is in threaded connection with the detection end. In this embodiment, the detection end and the small diameter section 2 are integrally formed, and the small diameter section 2 has external threads and is then connected with an internal threaded hole on the handle 1.
As shown in fig. 3 to 5, in the implementation, a detection tool is placed in the sealing oil port to perform detection and judgment in the following aspects:
(1) The detection tool cannot be completely placed in the sealing oil port, so that the diameter of the sealing conical surface is smaller, or the threaded hole and the sealing conical surface are not concentric, which causes that an oil pipe joint connected with the detection tool is subjected to larger lateral force, and the sealing effect cannot be realized;
(2) The detection tool is completely placed in the sealing oil port, and a larger shaking gap exists, so that the incorrect angle of the sealing conical surface can be judged, or the sealing conical surface is larger in diameter, and the sealing effect cannot be realized;
(3) The detection tool is placed into the sealing oil port, the angle fit of the sealing conical surface is tight, but the depth of the sealing conical surface is insufficient, so that the O-shaped sealing ring cannot be pressed into the sealing conical surface of the oil port during assembly, and the sealing effect cannot be realized;
combining the above 3 judging forms, the correct sealing oil port should meet the following requirements:
(1) The detection tool can be completely placed in the sealing oil port;
(2) The sealing angle is completely fit;
(3) The depth of the sealing conical surface is within the effective range of the detection tool.
The detection method generally comprises the following steps:
after the detection tool is put into the sealing oil port, the handle 1 is rocked, and whether the angle of the sealing conical surface is completely attached is observed through the observation port 6 on the detection tool; the detection tool is provided with an annular groove 5, and when the depth of the sealing conical surface is detected, the upper plane height of the sealing oil port must be in the upper edge and the lower edge of the annular groove 5.
