Description
Technical field
The utility model relates to a kind of surveying instrument, is specifically related to a kind of surveying instrument of the small size inner bore chamfering degree of depth.
Background technology
The detection of ferrule of take is example, and optical fiber is with low, the capacious advantage of its cost, more and more extensive in the application of the communications industry.National Ministry of Industry and Information in 2013 has promulgated that respectively " residential quarter and residential housing inner fiber are to family communications facility engineering design standard " and " residential quarter and residential housing inner fiber are to family communications facility engineering construction and acceptance specification " is to advance fiber-to-the-home construction, and therefore the porcelain bushing application quantity as the fiber adapter critical part also rises year by year.Therefore the ferrule quality testing also becomes particularly important.
The less ceramic structures for some endoporus, because in it, hole dimension is little, precision is high, many producers are carrying out chamfering process while producing, and are just controlling well under the prerequisite of chamfer angle, simple carry out by rule of thumb depth of chamfering control.To the measurement of undersized inner bore chamfering actual grade like this, still do not have in the market effective checkout equipment and detection method to be detected.Can not the be quantitative degree of depth be controlled, directly affected the cooperate degree of each parts, affects the usability of structural member.
The utility model content
In order to address the above problem, the utility model proposes a kind of surveying instrument and measuring method of the small size inner bore chamfering degree of depth, can accurately measure depth of chamfering, quantitative is controlled the degree of depth, improve the cooperate degree of each parts, improve the usability of structural member.
The utility model proposes in order to achieve the above object following technical scheme:
The surveying instrument of the small size inner bore chamfering degree of depth, it comprises handle, fixed ruler, slip chi, control knob, sounding rod and measuring head, handle is connected to fixed ruler one end, measuring head is fixedly connected on sounding rod, sounding rod is fixedly connected in the middle of the slip chi, and in the middle of control knob is contained in below the slip chi, the slip chi is stuck in the fixed ruler outside, be to be slidably matched between slip chi and fixed ruler, and on fixed ruler and slip chi, graduation indication arranged.
The identical semi-circular recesses of same sounding rod external diameter size equal length is contained at described fixed ruler back.
Graduation indication range on described fixed ruler is 5cm.
The long 49mm of scale on described slip chi, be divided into 100 little lattice, and each little lattice of slip chi and fixed ruler differ 0.01mm, reading=fixed ruler numerical value+slip chi lattice number * 0.01mm.
The surveying instrument depth survey scope of the described small size inner bore chamfering degree of depth is 0-3mm.
Described measuring head top is a cone, wherein the pyramid tip radius of a circle by the survey product even internal diameter size (getting tolerance on internal orifice dimension) of chamfered part not, the facies basialis pyramidis diameter is 3.0mm, the external diameter of sounding rod is 3.0mm.
The making material of described measuring head adopts zirconia or aluminium oxide ceramics.
The number of times of reusing of described measuring head is greater than 1000 times.
Described measuring head is designed with several specifications.These different size designs can be changed measuring head according to the needs of hole size in measuring and measuring accuracy.
The utility model has the advantages that surveying instrument simplicity of design precision, easy to use, can accurately measure depth of chamfering, quantitative is controlled the degree of depth, improves the cooperate degree of each parts, improves the usability of structural member.
