Description

A kind of external diameter measuring device
Technical field
The present invention relates to a kind of external diameter measuring device, the outside diameter measuring for being particularly used for the piston with slight elasticity fills Put.
Background technology
Piston is considered as the core part of oil cylinder, shock absorber, and whether detection piston items size meets design requirement particularly Important, the measurer of conventional measurement piston external diameter is external diameter micron micrometer, because the piston ring on the piston of some products is Composite, there is slight elasticity, when operator measures, size firmly can also have a certain impact to measurement data, measure Data can only also embody the overall size of tested certain point, it is difficult to it is accurate to judge whether test product qualified.
The content of the invention
It is an object of the invention to overcome the above-mentioned deficiency of prior art, there is provided a kind of external diameter measuring device, it can be eliminated Influence of the human factor to detection, it is accurate to judge whether test product is qualified.
To reach above-mentioned purpose, external diameter measuring device of the invention, including base, it is characterised in that the one of the base End is provided with block, and portion is provided with raised floor in the base, jack is provided with the base between block and floor, in block side Two horizontal locating dowels are installed with wall, the floor is provided with horizontal through hole, is provided with and the through hole phase in the side of through hole Horizontal notch even, clamping plate, an amesdial are installed in through hole the rib-shaped of notch upper and lower in a pair, the gauge head of amesdial Positioned at locating dowel side, the floor of notch upper and lower is bolted;
In use, bolt can be unclamped, the position of amesdial is adjusted;According to the upper limit value and lower limit value of tested piston, two standards are designed Gauge block, standard gauge block is positioned on base, the gauge head of two locating dowels and amesdial contacts with standard gauge block simultaneously, rotates mark Quasi- gauge block, determine the upper and lower limit position of amesdial pointer;When measuring product, piston is inserted in jack, two locating dowels and thousand Divide the gauge head of table to be contacted simultaneously with product, rotate test product, external diameter is accurately measured most by the skew of amesdial pointer Big value and minimum value, because the power that gauge head is applied on product external diameter is uniform, eliminate influence of the human factor to detection, and What is measured is the whole overall size of product, can accurately judge whether test product is qualified.
Brief description of the drawings
Fig. 1 is the top view of use state of the present invention.
Fig. 2 is Fig. 1 A-A profiles.
Embodiment
As shown in Fig. 1 and Fig. 2, the external diameter measuring device, including base 1, block 2 is provided with one end of the base 1, The middle part of base 1 is provided with raised floor 3, and jack 10 is provided with the base between block 2 and floor 3, solid in the side wall of block 1 Provided with two horizontal locating dowels 4, the floor 3 is provided with horizontal through hole, is provided with what is be connected with the through hole in the side of through hole Horizontal notch 5, clamping plate, an amesdial 6 are installed in through hole the rib-shaped of the upper and lower of notch 5 in a pair, the gauge head of amesdial 6 7 are located at locating dowel side, and the floor of the upper and lower of notch 5 is connected by bolt 8.
In use, bolt 8 can be unclamped, the position of amesdial 6 is adjusted;According to the upper limit value and lower limit value of tested piston, design two Individual standard gauge block, standard gauge block is positioned in jack 10, two locating dowels 4 and gauge head 7 contact with standard gauge block simultaneously, rotate Standard gauge block, determine the upper and lower limit position of amesdial pointer;During measurement, piston 9 is inserted in jack 10, two Hes of locating dowel 4 The gauge head 7 of amesdial 6 contacts with piston 9 simultaneously, rotates piston 9, accurately external diameter is measured by the skew of amesdial pointer Maximum and minimum value are as qualified between standard gauge block upper and lower limit.
