As shown in fig. 1-3, the utility model discloses an auxiliary device for hollow structure center positioning, include:

the cross-shaped frame body 1 is composed of two positioning plates which are vertically arranged, and the two positioning plates are provided with scales by taking the center of the cross-shaped frame body 1 as a symmetrical center;

the locating plate is located the both sides at the center of cross support body 1 all can slide and set up stopper 3, set up on the stopper 3 and instruct arrow point 4, its point portion is towards the scale to conveniently read the scale.

In the above embodiment, the cross frame body 1 is placed on the hollow structure to be detected, the cross frame body 1 is clamped on the hollow structure by moving the two limit blocks 3 on one of the positioning plates, and the two limit blocks 3 are temporarily fixed on the side edge of the hollow structure, because the limit blocks 3 are slidably arranged on the positioning plates, the cross frame body 1 can be continuously moved again, until the indication arrows 4 on the two limit blocks 3 align to the same scale, the bolt on the sliding limit clamp is screwed, which indicates that in the direction, the two limit blocks 3 are symmetrical along the center, and at this moment, the center of the cross frame body 1 is definitely on the positioning plate.
