Wherein, when carrying out measurement work, because work piece size and weight are different, need utilize measuring probe constantly to change the position to find the horizon point again when changing new work piece, the first direction of platform 10 promptly will keep being parallel with the first direction of frock 20, and the second direction of platform 10 will keep being parallel with the second direction of frock 20, just so can measure accurate data. When the position of the tool 20 is changed, that is, the coordinate origin of the tool 20 is changed, that is, the direction level in the first direction is misaligned, and the tool 20 is debugged only by changing the front, rear, left, and right positions of the tool 20, so that the coordinate origin of the tool 20 is consistent with the front end of the measurement probe. If the position of the tool 20 does not coincide horizontally with the position of the measurement probe, meaning that the origin of coordinates determined by the coordinate system is not accurate, then the measurement of the workpiece will be inaccurate.

Therefore, the tooling 20 needs to be positioned at a unique position, namely, the coordinate origin is unique, so that the position is not required to be manually aligned before each measurement, and a new origin is not required to be programmed again, thereby saving a great deal of time. As such, by providing the limiting member 30 on the platform 10, the limiting member 30 is provided on the upper surface of the platform 10, and the limiting member 30 includes: the first limiting surface and the second limiting surface are perpendicular to the projection of the first limiting surface and the projection of the second limiting surface on the platform 10, the intersection point of the projection of the first limiting surface and the projection of the second limiting surface on the platform 10 forms a coordinate origin of the positioning and measuring device 100, the tool 20 is placed at the position to be in close contact with the limiting part 30 before each measurement, the first limiting surface and the second limiting surface are attached to the edge of the tool 20, and therefore zero-making of the tool 20 can be achieved, the position of the tool 20 is consistent with the position of the measuring probe in the horizontal direction, and the measuring probe can measure a workpiece. In addition, after the tool 20 is calibrated once, the tool can be reused, and the time cost for positioning and changing the tool 20 is saved.

Therefore, the limiting part 30 is arranged on the platform 10, the only target original point is determined, and when the tool 20 is calibrated, the tool 20 can be directly attached to the limiting part 30, so that the tool is simple and accurate, and a large amount of time can be saved.
