Description

Technical Field

[0001] The utility model relates to the technical field of automobile welded pipes, in particular to a roundness detection device for automobile welded pipes. Background Art

[0002] Welded steel pipe, also known as welded pipe, is a steel pipe made by welding steel plates or strips after curling and forming. Automobiles are generally equipped with welded pipe fittings. After the welded pipe is processed, the welded pipe will be inspected, such as the roundness inspection of the welded pipe. This inspection device is used to detect the roundness of the welded pipe.

[0003] When processing automobile welded pipes, the quantity is usually large, and conventional inspection will use a measuring ruler to detect the roundness of the welded pipe. Since the ruler needs to be adjusted during inspection and then connected to the pipe fitting, the calibration is not convenient during measurement and the measurement efficiency is poor.

[0007] Preferably, the through openings and the through holes are connected to each other, and the through openings and the through holes are equidistantly distributed in the horizontal direction of the support.

[0008] Preferably, the through-columns and through-seats are fixedly connected, and the number of through-columns and through-seats is the same as the number of through-openings and through-holes.

[0009] Preferably, the middle opening is circular, and the middle opening and the dripping hole are connected.

[0010] Preferably, the drip holes are distributed at equal distances along the length direction of the middle opening.

[0011] Preferably, the support is snap-fitted to the side plate through the side opening, and the side plate and the plate strip are fixedly connected.

[0012] The utility model has at least the following beneficial effects:

[0013] 1. Through the movable penetration seat and the movable penetration column, the penetration column and the penetration seat can be moved. When in use, insert the automobile welded pipe into the middle mouth, and then move the penetration seat to make the penetration column fit tightly against the end wall of the welded pipe. Then observe the position difference between the penetration seats to see if they are flush, so as to determine whether the end wall of the welded pipe is round. Then rotate the welded pipe for one circle and continue to observe the position difference of the penetration seat, so as to further determine whether the welded pipe is round and quickly check the roundness of the welded pipe.

[0014] 2. The side dish is connected through the side opening. The dish cavity on the end wall of the side dish is used to place and fill dry powder, such as activated carbon particles. The dish strip made of sponge material is used to absorb water dripping from the drip hole, so as to keep the middle opening relatively dry. BRIEF DESCRIPTION OF THE DRAWINGS
