[0002] The existing special-shaped workpiece such as Figure 1 The L-shaped bend-through joint is provided with a through hole in the middle and an arc-shaped welding surface at one end to be welded with a cylindrical structure. The position of the through hole and the arc of the welding surface is usually detected by sticking to the arc surface, but the detection process can only be observed from the outside by naked eyes, and the inner part of the welding surface is difficult to observe by naked eyes. Therefore, the traditional detection tool is difficult to realize accurate detection of the welding surface. Meanwhile, the through hole structure is located in the center of the welding surface, and the welding surface itself is a special-shaped surface, so it is more difficult to detect the positional relationship and perpendicularity relationship between the through hole structure and the welding surface. Therefore, a detection tool capable of detecting the perpendicularity of the through hole and the position of the arc of the bend-through joint is needed. SUMMARY

[0005] The detection tool is a dial indicator.

[0006] The detection hole is parallel to the positioning column.

[0007] The positioning column is installed at the center of the detection surface.

[0008] The distance between the axis of the detection hole and the axis of the positioning column is less than the distance between the edge of the welding surface of the corresponding position of the bend-through joint and the axis of the through hole.

[0015] In order to make the above objectives, features and advantages of the utility model more apparent, below, specific embodiments of the utility model are described in detail in combination with the drawings. In the following description, a lot of specific details are set forth in order to fully understand the utility model. But the utility model can be implemented in many other ways different from the description, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed specific embodiments.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used in this description and the appended claims, the singular forms "a", "an" and "the" include plural references unless the context clearly dictates otherwise.

[0017] As Figures 2-3As shown, the utility model provides a kind of detection tool with cambered surface workpiece, including saddle base 1, positioning column 2 and detection tool 3, wherein the upper surface of the saddle base 1 is the detection face of arc, the curvature of detection face is same with the curvature of the welding surface of elbow joint, the positioning column 2 is vertically installed in the center of detection face, positioning column 2 can be connected with the through hole of elbow joint cooperation, and the height of positioning column is less than the depth of through hole;Detection groove 4 is equipped in the bottom surface of saddle base 1, detection hole 5 is equipped in the bottom of detection groove, detection hole 5 is through to the detection face of saddle base 1, detection tool 3 is installed in detection groove 4, and the detection head of detection tool 3 is installed in detection hole and extends the arc detection face on saddle base 1.

[0018] The detection tool 3 is a dial gauge.

[0019] The detection hole 5 is parallel to the positioning column 2, and more specifically, the axis of the detection hole is parallel to the axis of the positioning column, which is intended to improve detection. The detection hole 5 can also be designed to be perpendicular to the detection face, which allows for perpendicular detection of the distance and better overcomes the influence of errors (when parallel to the positioning column 2, an angle is formed with the detection face, which can cause the detection distance to be magnified, but has little effect on the detection result. A correction coefficient can be used to obtain the true distance).

[0020] The positioning column is installed at the center of the detection face, so that when the saddle base 1 is placed horizontally, the positioning column 2 is perpendicular to the horizontal surface and vertically upward, thereby providing more convenient support and detection.

[0021] The distance between the axis of the detection hole and the axis of the positioning column is less than the distance between the edge of the welding surface of the corresponding elbow joint and the axis of the through hole. This design allows the detection head in the detection hole to contact the welding surface of the elbow joint, thereby detecting the welding surface.

[0022] The side surface of the detection groove on the saddle base is machined with a fixing hole, and the detection tool is fixed in the detection groove.

[0023] The detection tool with cambered surface workpiece provided by the utility model is connected with the through hole of the elbow joint through the positioning column, so that the elbow joint can approach the detection face of the saddle base along the positioning column, and the fit degree of the welding surface of the elbow joint and the detection face of the saddle base can be detected by the detection tool.

[0024] The technical features of the above-described embodiments can be combined in any way. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0025] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
