Description

Technical Field

[0001] This utility model belongs to the field of pipe testing technology, specifically relating to a curved pipe surface contour detection and positioning device. Background Technology

[0002] After the piping system is manufactured, its dimensions need to be inspected to ensure its quality. During the batch manufacturing process, quality control is achieved through first-piece and last-piece inspections, meaning that the first and last pieces of each specification and model undergo three-dimensional inspection daily.

[0003] During the component manufacturing process, dimensions need to be measured using a three-dimensional measuring machine. However, because the component shape is curved and cannot be fixed, the three-dimensional measurement has a large error. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a curved pipe surface contour detection and positioning device, which has the advantage of being easy to fix.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a curved pipe surface contour detection and positioning device, comprising a base, a column fixedly connected to the top outer wall of the base, an inwardly recessed groove on the outer wall of the column, the inner wall of the groove fitting against the outer wall of the product, three positioning pins fixedly connected to the outer wall of the column, studs fixedly connected to the outer wall of the column, a pressure plate fixedly connected to the outer wall of the studs, and a nut provided on the outer wall of the studs.

[0006] The above technical solution facilitates fixation. The groove on the column is a contour groove. The component is fixed by the contour section and three positioning posts. The two pressure plates are tightened with nuts and pins to the bent pipe. Finally, the component size is tested with a three-dimensional measuring machine. If it meets the drawing specifications, it is considered OK; otherwise, it is considered NG. The use of curved surface contour tooling can ensure that the accuracy of dimensional inspection is improved and the measurement and production costs are reduced during component inspection.

[0007] Preferably, the distance between the three positioning posts is equal, forming an equilateral triangle.

[0008] The above technical solution can achieve a three-point contact effect. Since the pipe is circular, the distance between the positioning posts is equal, forming an equilateral triangle, which allows all three positioning points to contact the pipe, thereby ensuring the pipe is fixed.

[0009] Preferably, the three positioning posts have the same height and their tops are coplanar.

[0010] The above technical solution ensures that the pipe is level, and that the three positioning posts are of equal height and have coplanar tops, thus ensuring that the surface of the pipe in contact with the positioning posts remains level.

[0011] Preferably, the bottom surface of the pressure plate is higher than the top surface of the positioning post.

[0012] The above technical solution can achieve a fixing effect. The bottom surface of the pressure plate is higher than the top surface of the positioning post, which allows the pressure plate to press on the surface of the pipe, thereby fixing the pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The groove on the column is a contour groove. The component is fixed by the contour section and three positioning posts. The two pressure plates are tightened with nuts and pins to the bent pipe. Finally, the component size is tested with a three-dimensional measuring machine. If it meets the drawing specifications, it is considered OK; otherwise, it is considered NG. Using curved surface contour tooling can ensure that the accuracy of dimensional inspection is improved and the measurement and production costs are reduced during component inspection.

[0015] 2. Since the pipe is circular, the distance between the positioning posts is equal, forming an equilateral triangle, which allows all three positioning points to contact the pipe, thus ensuring the pipe is fixed. The three positioning posts have the same height and their tops are coplanar, which ensures that the surface of the pipe in contact with the positioning posts remains horizontal.
