Abstract
The utility model relates to a measuring tool, concretely to a cardboard measuring tool for measuring an external diameter of a cylinder part groove bottom, wherein the cardboard measuring tool is characterized by comprising a cardboard main body, wherein a waist-shaped gap is arranged on the cardboard main body, an arc-shaped end part is arranged at the waist-shaped gap, both sides of the arc-shaped end part respectively extends toward to the root part of the cardboard main body to form two sets of parallel tangent planes, the tangent plane are a first tangent plane and a second tangent plane, a vertical distance between the two sets of the tangent planes is slightly larger than a vertical distance between both end on the arc-shaped end part, and the two sets of the tangent planes end at the root part of the cardboard main body. Compared with the cardboard measuring tool in the prior art, the cardboard measuring tool of the utility model has the following characteristics that: measurement methods employing the traditional external diameter micrometer and the vernier caliper are canceled, the measurement error and the generation of reading error can be avoided, and the cardboard has the advantages of simple structure, convenient usage, and simple and visual measurement determination.
Description
Technical field
The utility model relates to a kind of measurer, specifically a kind of clamp measurer of measuring cylindrical part bottom land external diameter.
Background technology
At present general vernier caliper and the outside micrometer of adopting in the measurement of cylindrical part bottom land external diameter measured, but the vernier caliper measurement error is bigger, mistake appears in reading judgement easily.Though it is and outside micrometer precision height error in reading occurs easily on measuring, convenient inadequately in the use.
Summary of the invention
The utility model provides a kind of clamp measurer of measuring cylindrical part bottom land external diameter in order to overcome the deficiencies in the prior art.
To achieve these goals, the utility model has designed a kind of clamp measurer of measuring cylindrical part bottom land external diameter, it is characterized in that: comprise the clamp main body, offer a waist v notch v on the clamp main body, the waist v notch v has a circular arc end, the root of two side direction clamp main bodys of circular arc end extends to form two groups of tangent planes parallel to each other, be respectively first tangent plane and second tangent plane, the vertical range that vertical range between these two groups of tangent planes is a bit larger tham two ends, circular arc end, and these two groups of tangent planes end at the root of clamp main body.
Described first tangent plane and second tangent plane adopt arc transition with the root of clamp main body respectively.
The dimensional tolerence that cooperates cylindrical part to be processed, in advance the waist v notch v on the clamp main body is processed, the root of waist v notch v is the maximum allowance size, the end of waist v notch v is the minimal tolerance size, when the external diameter of cylindrical part can't enter the root of waist v notch v, the oversize technological requirement that do not meet of cylindrical part this moment is described; When the external diameter of cylindrical part enters the root of its waist v notch v, and be fastened on fully in the circular arc end, the undersized technological requirement that also do not meet of cylindrical part this moment is described; Have only external diameter when cylindrical part to enter the waist v notch v and be fastened between the root and end of waist v notch v, this moment, the size of cylindrical part had the tolerance range of a standard, met technological requirement.
The utility model is compared with prior art, has cancelled and has adopted traditional outside micrometer and vernier caliper measurement mode, avoids occurring measuring error, and the situation of error in reading takes place.And the utility model is simple in structure, and it is more convenient to use, and measures and judges simple, intuitive more.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 can't enter the structural representation of waist v notch v for cylindrical part in the utility model use.
Fig. 3 enters the structural representation of waist v notch v root for cylindrical part in the utility model use.
Fig. 4 is fastened on structural representation between waist v notch v root and the end for cylindrical part in the utility model use.
Referring to Fig. 1 to Fig. 4,1 is the clamp main body; 2 is the waist v notch v; 3 is the circular arc end; 4 first tangent planes; 5 is second tangent plane; 6 is cylindrical part; 7 is circular arc.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the utility model comprises clamp main body 1, offer a waist v notch v 2 on the clamp main body 1, waist v notch v 2 has a circular arc end 3, the root of two side direction clamp main bodys 1 of circular arc end 3 extends to form two groups of tangent planes parallel to each other, be respectively first tangent plane 4 and second tangent plane 5, the distance that distance between these two groups of tangent planes is a bit larger tham two ends, circular arc end, and these two groups of tangent planes end at the root of clamp main body 1, and adopt circular arc 7 transition with the root of clamp main body respectively.
Specific operation process is as follows.
The outside dimension that cooperates cylindrical part 6 to be processed is processed the waist v notch v 2 on the clamp main body 1 in advance, and the root of waist v notch v 2 is the maximum allowance size, and the end of waist v notch v 2 is the minimal tolerance size.
As shown in Figure 2, when the bottom land external diameter of cylindrical part 6 can't enter the root of waist v notch v 2, the excessive technological requirement that do not meet of bottom land external diameter of cylindrical part 6 this moment is described.
As shown in Figure 3, when the bottom land external diameter of cylindrical part 6 enters the root of its waist v notch v 2, and enter fully in the circular arc end, the too small technological requirement that also do not meet of bottom land external diameter of cylindrical part 6 this moment is described.
As shown in Figure 4, have only bottom land external diameter when cylindrical part 6 to enter waist v notch v 2 and be fastened between the root and end of waist v notch v 2, this moment, the bottom land external diameter of cylindrical part 6 had the tolerance range of a standard, met technological requirement.First tangent plane 4 in the utility model and second tangent plane 5 adopt circular arc 7 transition with the root of clamp main body 1 respectively in addition, and the bottom land external diameter of being convenient to cylindrical part enters in the waist v notch v 2, avoids the scratch part.
Compare with prior art, cancelled and adopted traditional outside micrometer and vernier caliper measurement mode, it is big to avoid measuring error occurring, and the situation of error in reading takes place.And the utility model is simple in structure, and it is more convenient to use, and measures and judges simple, intuitive more.
