As shown in fig. 1 to 9, the present embodiment provides a detection tool for assembling a cylindrical workpiece, which is used for detecting the coaxiality between the cylindrical workpiece 100 and an output shaft 200 of a driving unit, wherein the driving unit is used for driving the cylindrical workpiece 100 to rotate, and the cylindrical workpiece 100 is sleeved outside the output shaft 200 of the driving unit. The cylindrical workpiece 100 is vertically arranged, specifically, a connecting flange 201 is fixedly arranged on an output shaft 200 of the driving unit, an outer cylinder flange 101 is fixedly arranged on the inner wall of the middle part of the cylindrical workpiece 100, and after the assembly is completed, the outer cylinder flange 101 is fixedly connected with the connecting flange 201. In this embodiment, the cylindrical workpiece 100 is an outer cylinder of a wind-driven main thrust rotor, has a diameter up to six meters and a height of thirty meters, and rotates at a high speed during operation. Therefore, it is necessary to detect whether the axis of the cylindrical workpiece 100 coincides with the axis of the output shaft 200 of the driving unit when the cylindrical workpiece 100 is assembled, so as to ensure that the cylindrical workpiece 100 can run smoothly.
Specifically, the detection tool for assembling the cylindrical workpiece comprises a first distance measuring unit 1 and a second distance measuring unit 2, wherein the first distance measuring unit 1 and the second distance measuring unit 2 are sequentially arranged at intervals from top to bottom along the axis of the cylindrical workpiece 100. The first distance measuring unit 1 is used for detecting the coaxiality between the middle part of the cylindrical workpiece 100 and the output shaft 200 of the driving unit, and since the length of the cylindrical workpiece 100 is long, only the axis of the middle part of the cylindrical workpiece 100 is ensured to be coincident with the axis of the output shaft 200 of the driving unit, but it cannot be represented that the axis of the bottom part of the cylindrical workpiece 100 is also coincident with the axis of the output shaft 200 of the driving unit, so that the coaxiality between the bottom part of the cylindrical workpiece 100 and the output shaft 200 of the driving unit needs to be detected by the second distance measuring unit 2.

Assuming that the first distance measuring part 12 is arranged at a first preset height inside the cylindrical workpiece 100 and located in the middle of the cylindrical workpiece 100, which is equivalent to taking a plurality of detection points at different positions on the inner peripheral wall of the cylindrical workpiece 100 corresponding to the first preset height, it should be noted that the inner peripheral wall of the cylindrical workpiece 100 corresponding to the first preset height is a circle, and the plurality of detection points are distributed along the circle, and the first distance measuring part 12 is utilized to measure the distances between the plurality of points and the first distance measuring part 12 to obtain a plurality of distance values, since the first distance measuring part 12 rotates along the first supporting part 11 with the axis of the output shaft 200 of the driving unit as the rotation center, if the plurality of distance values are the same, it is indicated that the axis of the middle of the cylindrical workpiece 100 coincides with the axis of the output shaft 200 of the driving unit, and there is no need to adjust the position of the cylindrical workpiece 100. If the values of the plurality of distance values are different, it is indicated that the axis of the middle part of the cylindrical workpiece 100 does not coincide with the axis of the output shaft 200 of the driving unit, and the position of the cylindrical workpiece 100 can be adjusted according to the plurality of distance values, and the detection can be performed again until the axis of the middle part of the cylindrical workpiece 100 coincides with the axis of the output shaft 200 of the driving unit.

Assuming that the second distance measuring part 22 is disposed at a second predetermined height inside the cylindrical workpiece 100 and located at the bottom of the cylindrical workpiece 100, which is equivalent to taking a plurality of detection points at different positions on the inner peripheral wall of the cylindrical workpiece 100 corresponding to the second predetermined height, it should be noted that the inner peripheral wall of the cylindrical workpiece 100 corresponding to the second predetermined height is a circle, and the plurality of detection points are distributed along the circle, and the second distance measuring part 22 is utilized to measure the distances between the plurality of detection points and the second distance measuring part 22 to obtain a plurality of distance values, since the second distance measuring part 22 rotates along the second supporting part 21 with the axis of the output shaft 200 of the driving unit as the rotation center, if the plurality of distance values are the same, it is indicated that the axis of the bottom of the cylindrical workpiece 100 coincides with the axis of the output shaft 200 of the driving unit, and there is no need to adjust the position of the cylindrical workpiece 100. If the values of the plurality of distance values are different, it is indicated that the axis of the bottom of the cylindrical workpiece 100 does not coincide with the axis of the output shaft 200 of the driving unit, and the position of the cylindrical workpiece 100 can be adjusted according to the plurality of distance values, and the detection is performed again until the axis of the bottom of the cylindrical workpiece 100 coincides with the axis of the output shaft 200 of the driving unit, and simultaneously, the axis of the middle of the cylindrical workpiece 100 coincides with the axis of the output shaft 200 of the driving unit, so that the assembly requirement of the cylindrical workpiece 100 is met.
