The invention discloses a steel pipe outer circle flatness testing device which comprises a rotating shaft first fixing end plate, a rotating shaft second fixing end plate, a sliding rail, a dial indicator fixing rod, a dial indicator, a dial indicator fixing piece, a first bearing first mounting block, a first bearing, a first bearing second mounting block, a second bearing, a rotating shaft, a limiting plate, a first bearing groove, a third bearing and a fixing bolt. When in use, the pipe A is sleeved on the rotating shaft 11. A fixing bolt 15 penetrates through the through hole and the through hole in the rotating shaft 11 to fix the pipe A. When the rotating shaft 11 is rotated, the pipe A rotates, the plurality of dial indicators measure the perimeter of the pipe at multiple positionsof the pipe, and when the perimeters readings of all the dial indicators are the same, the flatness of the outer circle of the pipe A is good. The steel pipe outer circle flatness testing device is simple in structure and convenient to operate, and the flatness of the outer circle of the pipe can be rapidly tested.
Description
technical field [0001] The invention relates to a test device for the flatness of the outer circle of a steel pipe. Background technique [0002] During the manufacturing process of the steel pipe, the flatness of the outer circle of the steel pipe needs to be tested. The conventional method is to manually use a measuring tool for sampling measurement, and the measuring tool includes a vernier caliper and the like. The efficiency of the above-mentioned test is low, and the accuracy of the measurement is greatly affected by human factors, which is prone to deviation. Contents of the invention [0003] The object of the present invention is to provide a test device for the flatness of the outer circle of a steel pipe, aiming at solving the above-mentioned problems. [0004] In order to achieve the above object, the technical solution of the present invention is to design a steel pipe outer circle flatness test device, including the first fixed end plate of the rotating shaf...
