Background
In the field of machining, the product quality is directly influenced by the accurate measurement of the size of a part, most of measuring tools for measuring the depth size are vernier calipers and depth gauges at present, but in the depth size shown in figure 1, the conventional measuring tool cannot realize accurate measurement due to the fact that the bottom of the detected size is of an arc structure. To above circumstances, the utility model relates to a special frock and measuring method can realize the precision measurement, and easy and simple to handle and with low costs.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model provides a depth dimension of annular circular arc bottom structure part measures frock to the position that conventional survey utensil can't detect is measured to the precision.
The technical scheme of the utility model:
first aspect provides an annular circular arc bottom structure part degree of depth dimension measurement frock, includes: the upper surface of the base is a plane and is parallel to a plane formed by the lowest point of the detection ring; the detection ring is located below the base and integrally formed with the base, the diameter of the bottom arc part of the detection ring wall is smaller than that of the bottom arc structure part of the part to be detected, the diameter formed by the lowest point of the detection ring is consistent with that formed by the lowest point of the bottom arc part of the part to be detected, the tolerance is smaller than a preset threshold value, and the distance between the upper surface of the base and the plane formed by the lowest point of the detection ring is larger than the detection depth of the part to be detected.
Further, the diameter of the circular arc part at the bottom of the detection ring wall is the thickness of the detection ring wall.
Furthermore, the central line of the wall thickness of the detection ring wall passes through the circle center of the bottom arc of the detection ring wall.
Further, the lower surface of the base is higher than the upper surface of the part to be detected, so that detection interference is avoided.
Further, for the part to be measured with the diameter smaller than 100mm, the flatness of the upper surface of the base is not larger than 0.003 mm.
Further, for the part to be detected with the diameter smaller than 100mm, the parallelism of a plane formed by the upper surface of the base and the lowest point of the detection ring is smaller than 0.01 mm.
Has the advantages that:
the utility model discloses measurement accuracy is high, can realize the size that conventional measuring tool can't detect, and is easy and simple to handle, with low costs and efficient.
