The auxiliary measuring fixture block is characterized in that two bosses are arranged on the tool body for measuring the angle from the circular point to the surface, and a depth caliper is arranged between the two bosses.
The head conical surface and the middle-rear conical surface are made into the same specification according to the size, the angle and the taper of the circular arc of a specific product.
The bevel is matched with the measured round sharp angle, namely the bevel is attached to the measured round sharp angle, and no shaking in the axial direction is guaranteed.
The conical surface of the head part is matched with the conical surface of the round tip, namely the conical surface of the head part and the conical surface of the round tip are attached to each other, so that no shaking is ensured in the axial direction.
The conical surface of the middle rear part is matched with the cone of the middle rear part of the workpiece to be detected, namely the conical surface of the middle rear part and the cone of the middle rear part of the workpiece to be detected are jointed, so that no shaking is ensured in the axial direction.
The length from the sharp corner to the surface is between the break angle on the sharp corner to the surface measuring tool body and the measured workpiece.
The utility model discloses have following positive effect:
1. the tool itself has a conical surface which is matched with the conical surface of the round sharp pyramid to play a role in positioning.
2. The fixture block for assisting the depth caliper measurement also plays a positioning role.
The auxiliary error of the measuring tool from the sharp corner to the surface can be controlled to be 0.05mm, the product inspection precision is improved, and the quality assurance of the product is enhanced. Consequently the utility model has the advantages of simple structure, the function is practical, solves the unable measuring actual problem of face, measured value more accurate of round closed angle.

Detailed Description
As shown in fig. 1, 2, 3 and 4, a measuring tool for measuring the length from a circular cusp to a plane comprises a circular cusp to plane measuring tool body 2, a head conical surface 5 matched with a circular cusp conical surface of a measured workpiece 4 is arranged on the head part from a circular cusp angle 8 to the lower surface of the plane measuring tool body 2, a middle rear conical surface 6 matched with a middle rear cone of the measured workpiece 4 is arranged on the middle rear part below the circular cusp to plane measuring tool body 2, a break angle is formed between the head conical surface 5 and the middle rear conical surface 6 and matched with the circular cusp angle to be measured, and an auxiliary measuring fixture block 1 matched with a depth caliper 3 is arranged on the head part from the circular cusp angle to the upper surface of the plane measuring tool body 2.
The auxiliary measuring fixture block 1 is characterized in that two bosses are arranged on the measuring tool body 2 from the sharp corner to the surface, and a depth caliper 3 is arranged between the two bosses.
The head conical surface 5 and the middle rear conical surface 6 are made into the same specification according to the size, the angle and the taper of the circular arc of a specific product.
The bevel is matched with the measured round sharp angle, namely the bevel is attached to the measured round sharp angle, and no shaking in the axial direction is guaranteed.
The conical surface 5 of the head part is matched with the conical surface of the circular tip, which means that the conical surface and the conical surface are attached to each other, so that no shaking is ensured in the axial direction.
The conical surface 6 of the middle rear part is matched with the cone of the middle rear part of the workpiece 4 to be detected, namely the two are attached to each other, so that no shaking is ensured in the axial direction.
The length 7 from the sharp corner to the surface is arranged between the break angle of the sharp corner to the surface measuring tool body 2 and the measured workpiece 4.
The conical surface matched with the round sharp angle in the measuring tool positions the round sharp angle, the depth caliper 3 is installed on the auxiliary measuring fixture block 1 for positioning measurement, and the distance from the round sharp angle to the surface is obtained through conversion.
