Abstract
The utility model relates to a go-no go pin gauge. The go-no go pin gauge comprises a hand-held portion, wherein the hand-held portion is connected with a go-no go pin, and the go-no go pin comprises a pin head positioned in an end portion of the go-no go pin. Tangents of cross-section edges of the pin are positioned outside the cross section, a minimum distance between two parallel tangents of the cross-section edges is a lower limit value of a to-be-measured size, and a maximum distance between two parallel tangents of the cross-section edges is an upper limit value of the to-be-measured size. During measurement, the pin is placed into a to-be-measured size position, the direction of the minimum distance of two parallel tangents are made as the same as the direction of the to-be-measured size, and the pin is then rotated to the direction of the maximum distance of two parallel tangents. If the pin can be accommodated and can not be completely rotated, the to-be-measured size is in the range of tolerance. The measurement can be finished in one time, which is convenient and fast.
Description
Technical field
The utility model relates to a kind of logical shotpin rule.
Background technology
The private volumn cubing is the non-standard checkout equipment that generally uses during auto parts and components are produced.Logical shotpin rule are a kind of of measurer, because it is simple in structure, easy to use, cost is relatively cheap, in being widely used in producing in enormous quantities.
When using cubing to measure, first part is placed in advance and carries out on the cubing of copying and reservation standard voids according to part shape, re-using register pin and chuck is fixed on part on the cubing, the key element of using at last various pin gauges need to measure part is carried out observational measurement, thereby understand the change in size trend of measured key element, carry out the control of size and the monitoring of quality.Common logical shotpin rule, center section is the Handheld Division, two ends are respectively drift and no-go gage.When measuring, need to measure with drift and no-go gage respectively, confirm that accessory size is whether within margin tolerance.Adopt this logical shotpin rule, need to measure twice with drift and no-go gage respectively, measurement is inconvenient, and efficient is lower.
The utility model content
The technical problems to be solved in the utility model provides easily logical shotpin rule of a kind of measurement, and these logical shotpin rule only need to measure once, just can determine rapidly that the size to be measured of part is whether in margin tolerance.
For solving the problems of the technologies described above, the utility model comprises the Handheld Division, and the Handheld Division is connected with logical shotpin post, and logical shotpin post comprises the plunger that is positioned at the end; The tangent line of the cross-sectional edge of plunger all is positioned at the outside of xsect, and the minimum value of two parallel tangents distances of cross-sectional edge is the lower limit of size to be measured, and the maximal value of two parallel tangents distances of cross-sectional edge is the higher limit of size to be measured.During measurement, plunger is put into size to be measured place, the direction of the bee-line of Schilling two parallel tangentss is identical with the direction of size to be measured, again with the direction rotation of plunger to the longest distance of two parallel tangentss, if plunger can be put into, and can not rotate fully, then this size to be measured is positioned within the margin tolerance, measuring only needs once can finish, convenient and swift.
Preferably, the quadrilateral of symmetry centered by the xsect of plunger, wherein one group of Symmetry Edge is straight line parallel to each other, another group Symmetry Edge is the circular arc take symcenter as the center of circle.During measurement, can spacing and the size to be measured with two parallel surfaces compares first, rotates plunger again, rotate this size to be measured of judgement fully by plunger and whether be positioned at margin tolerance.The setting of this parallel surface is more easily located survey crew, has made things convenient for survey crew to judge whether size to be measured satisfies lower limit.
Preferably, logical shotpin post also comprises connecting portion, and an end of connecting portion is connected with plunger, and the other end of connecting portion is connected with the Handheld Division.Connecting portion can design different shapes according to the particular location of the size to be measured of part, makes plunger can enter easily size to be measured place, has made things convenient for the measurement of survey crew.
Description of drawings
Fig. 1 is the structural representation of the logical shotpin rule of the utility model.
Fig. 2 is the diagrammatic cross-section of the X-X of logical shotpin rule shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
To shown in Figure 2, the logical shotpin rule of the utility model comprise Handheld Division 1 such as Fig. 1, and Handheld Division 1 is connected with logical shotpin post 2, and logical shotpin post 2 comprises the plunger 21 that is positioned at the end; The tangent line of the cross-sectional edge of plunger 21 all is positioned at the outside of xsect, and the minimum value of two parallel tangents distances of cross-sectional edge is the lower limit of size to be measured, and the maximal value of two parallel tangents distances of cross-sectional edge is the higher limit of size to be measured; The quadrilateral of symmetry centered by the xsect of plunger 21, wherein one group of Symmetry Edge is straight line 211 parallel to each other, another group Symmetry Edge is the circular arc 212 take symcenter as the center of circle; Logical shotpin post 2 also comprises connecting portion 22, and an end of connecting portion 22 is connected with plunger 21, and the other end of connecting portion 22 is connected with Handheld Division 1.
Do not need during measurement to measure respectively twice with go side and not-go-end, only need to lead to shotpin rule and put into size to be measured place, if logical shotpin rule can not be rotated fully, then this size to be measured is positioned within the margin tolerance, only needs once can finish measurement, and is convenient and swift.
Suppose that the gap between part and the benchmark shape face is 3mm, the tolerance in this gap is ± 0.5mm, and then the length of the longest line of logical shotpin rule is 3.5mm, and two Face Parallel Clearance are 2.5mm.Insert in the measurement clearance take parallel surface as benchmark first, if plunger can't rotate freely, the size conforms size tolerance requirements to be measured of part is described then in the gap.
The above a kind of logical shotpin rule that the utility model embodiment is provided are described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; all will change in specific embodiments and applications; in sum; this description should not be construed as restriction of the present utility model, and all any changes of making according to the utility model design philosophy are all within protection domain of the present utility model.
