Detailed Description
The utility model is described in further detail below with reference to the embodiments of the drawings.
Embodiment one: as shown in fig. 1 to 4, a hole position detecting tool for a hole of a hole punching bolt comprises a cylinder 2 and a detecting rod 3, wherein a plurality of detecting holes 21 are formed in the side face of the cylinder 2, one end of the detecting rod 3 penetrates through one detecting hole 21 and is inserted into the cylinder 2, when the cylinder 2 is sleeved on a rod portion 12 of the hole punching bolt 1 to be detected, one end of the cylinder 2 is abutted against a head portion 11 of the hole punching bolt 1 to be detected, and the detecting hole 21 in the cylinder 2 corresponds to and is communicated with a hole 14 in the hole punching bolt 1.
In the clock of the embodiment, the detecting hole 21 is a waist-shaped hole, the long axis of the waist-shaped hole is parallel to the axis of the cylinder 2, and the short axis of the waist-shaped hole is consistent with the aperture of the through hole 14 on the punching bolt 1 to be detected. Since the hole diameter of the through hole 14 on the punching bolt 1 has a certain tolerance range, the hole diameter of the detection hole 21 is lengthened, the lengthened length is recorded as t, and t corresponds to the tolerance upper limit of the hole diameter of the through hole 14, so that the punching bolt hole position degree detection tool can accurately detect the position degree of the through hole 14 on the punching bolt 1 to be detected.
In this embodiment, one end of the detecting rod 3 is provided with a sloped guide surface 31 inclined from inside to outside toward the other end thereof, facilitating insertion of the detecting rod 3 into the detecting hole 21, through-hole 14.
