In the technical scheme disclosed in one or more embodiments, as shown in fig. 1, an anchor bolt detection caliper capable of determining an error range comprises a caliper body 1 and a vernier 2 movably arranged on the caliper body 1; a reading frame 4 is arranged on the vernier 2, scale marks 3 are arranged on the caliper body 1, and at least two scale marks are arranged at each scale indication position; setting the size and position of the scale marks and the reading frame, and determining an error range according to the positions of the scale marks of the scale indication positions in the reading frame.
In this embodiment, by providing a plurality of graduation marks 3 at each graduation indicating position, and providing a reading frame 4 for observing the graduation marks, it is possible to pass the positions of the graduation marks 3 in the reading frame 4, the size error of the currently measured bolt or nut is directly and intuitively determined, and the error can be judged whether to be in a required error range without estimating and reading, so that the accuracy and the efficiency of measurement are improved.
In some embodiments, the configuration of the error range reading frame 4 may be determined based on the size and shape of the graduation line and the reading frame, and the frame of the reading frame 4 in the overlapping region with the graduation line 3 is set as the hypotenuse 4-1 on the path of travel of the vernier 2.
According to a further technical scheme, the reading frame 4 is arranged to be polygonal, and the frame of the reading frame in the area overlapped with the scale marks is arranged to be a bevel edge 4-1. The number of sides of the reading frame set as a polygon may be arbitrary, and is set as a hexagon in this embodiment.
In some embodiments, the bevel edges 4-1 of the overlapping area of the reading frame 4 and the graduation marks 3 are symmetrically arranged in two ways, and the connection point of the two bevel edges is the highest point A or the lowest point B.
In the processing process of the bolt and the nut, certain errors exist in the size, and when the size errors of the finished product are in a set range, namely the size errors meet the requirements, whether the size errors are in the required error range can be directly determined through the position of the observation window 4 where the scale mark 3 is located on the caliper.
In a specific implementation scheme, the dimensional error of the measured bolt and nut is determined, as shown in fig. 1, two scale marks of each scale indication position are set, and the distance between the two scale marks of each scale indication position is set according to the error range, so that the highest point A or the lowest point B of the reading frame 4 is positioned between the two scale marks of the same scale position, the error is qualified, and otherwise, the error exceeds the error range.
As a specific example, as shown in fig. 2 and 3, the error of the measuring component is qualified, as shown in fig. 2, the highest point a is between two graduation marks, and as shown in fig. 3, the error of the measuring component is unqualified, and the highest point a is not between graduation marks.
