Description
Technical field
The present invention relates to the length measurer, be specifically related to diameter measuring tool in a kind of spreading formula wide range.
Background technology
There are Chengdu measuring and cutting tool company limited, Measuring & Cutting Tools Plant, Qinghai and Harbin measuring and cutting tool group company etc. in the producer of the wide range of China's production at present micrometer inside caliper, and maximum range is 6000mm.Surpass this size, because material and structural reason, the blade distortion is big, and this all also is in the exploratory stage at home and abroad, does not all have finished product to supply buying both at home and abroad.For satisfying in the Large-Scale Equipment industrial processes requirement to large-scale internal diameter size precision measurement, surpass the large diameter precision measurement of 6000mm like Three Gorges hydraulic generator unit, more domestic enterprises develop large-scale integral formula micrometer inside caliper voluntarily and solve.Large-scale integral formula micrometer inside caliper belongs to the monoblock type large diameter measurement mechanism of fixed measure.Its advantage is that indicating value is stable, directly measures, and without operating personnel's spreading, but also has serious problem: one of which, only energy measurement single size, not extensible.The occasion of needs being measured a series of sizes just can't solve, and often needs to be equipped with many monoblock type micrometer inside calipers, its two, the cost of transportation and packing monoblock type micrometer inside caliper is too big.Because the monoblock type micrometer inside caliper size of mounting site that mails to the power station is usually more than 7000mm, for transport one only more than 20 kilogram measurer need truck more than 10 tons, and to carry out anticollision, the multi-layer packaging of vibration proof modification has more strengthened production cost.
Summary of the invention
The object of the invention provides diameter measuring tool in a kind of wide range of extensible, and its range is 6000～10000mm, can satisfy the measurement requirement of large-scale workpiece.The main difficult point that designs this measurer is:
1. for ease of transportation, the main scale of measurer is designed to two sections, two sections are adopted any mode to connect, and could guarantee the right alignment of each section, and are convenient to adorn, tear open.
2. measurer is very long, and how the meeting downwarp reduces amount of deflection during use, guarantees measuring accuracy.
3. measurer is very long, how to reduce weight as far as possible, is convenient to measuring operation, to alleviate labor intensity of operating personnel.
To above-mentioned difficult point, the present invention adopts following technical proposals:
Diameter measuring tool in a kind of spreading formula wide range, its range are made up of blade and the chi head, the chi tail that are connected the blade two ends greater than 6000mm, and said blade comprises main scale and extension bar, and extension bar is between main scale and chi head; Said main scale connects and composes by two sections; Adopt the anchor ear locker to connect between two sections sections; This anchor ear locker comprises pair of pipes joint, a centralized positioning ring, one group of anchor ear by some segmental arc combination lopping; Said pipe adapter is welded on the port in opposite directions of adjacent two blade sections respectively, has a ring wedge groove on the outer cylinder of pipe adapter, is used for cooperating with anchor ear; The end face of pipe adapter and inner cylinder angle of cut portion have the positioning step seam, and said centralized positioning ring is positioned at the positioning step seam of two pipe adapters; Be distributed with some screws on the periphery of centralized positioning ring; The cross sectional shape of said anchor ear is " U " shape; Its ear is a pair of wedge, and the wedge groove of this wedge and pipe adapter is suitable, and screw perforation is arranged on the anchor ear; Screw on its quantity, the corresponding centralized positioning dish in position; This anchor ear is connected with the centralized positioning ring by screw, and the wedge of anchor ear is fixedly connected two sections main scales two pipe adapter wedgings.
The contour shape of said blade is a spindle, and its diameter is reduced to the two ends dullness by mid point.
Said main scale is processed with thin-wall steel tube, and the steel pipe inwall is lined with ring stiffener; The wall thickness of said steel pipe is 1mm.
The length of said extension bar is 500mm, 1000mm, three kinds of specifications of 1500mm, but combination in any.
Said extension bar is furnished with core bar.
Said chi head adopts thousand fens micrometer heads, and said chi tail adopts dial gauge.
Technique effect of the present invention:
Because the blade main scale is divided into two sections, be convenient to transportation, two sections main scales adopt the anchor ear locker to connect, and right alignment is good, and measuring accuracy is high, and easy to loading and unloading; The contour shape of blade is a spindle, and inwall is lined with ring stiffener, and structural strength is good, and amount of deflection is little during use; Blade is processed with thin-wall steel tube, and weight is little, is convenient to operation, can alleviate labor intensity of operating personnel.
