Description

The machinery formula height gauge that makes zero

Technical field

The utility model relates to a kind of height gauge, and particularly a kind of machinery formula height gauge that makes zero belongs to machinery mapping utensil field.

Background technology

Height gauge has widely as a kind of precision measurement instrument to be used, at work through being commonly used to measure absolute altitude and relative height, when measuring absolute altitude, common cursor type and electronic digital display type can both well be satisfied the demand, when measuring relative height, because the electronic digital display type height gauge can arrange zero point in the optional position, therefore can carefully satisfy the measurement of relative height uses, but the electronic digital display type height gauge is again and again button many times in use, be easy to cause breaking down, for some old technician, a lot of people are not familiar with the electronic digital display type height gauge so that are difficult to launch and use, still be accustomed to the height gauge with the sort of common cursor type, think that it is directly perceived, at least can really see earnestly the measurement result with scale mark, and the digimatic height gage price will be far above standard machinery formula height gauge, present common cursor type height gauge is when measuring or rule, when measuring relative height, because can not be set arbitrarily zero point (making zero), often need to calculate the difference of two or several measurement numerical value, need to record and calculate a large amount of data when bringing problem to be measurement in the work of giving, produce larger workload, simultaneously because data are processed the more miscalculation that misremembers easily.

Summary of the invention

The utility model can make standard machinery formula height gauge make zero arbitrarily for a kind of machinery formula height gauge that makes zero is provided, and realizes easily the measurement of relative height.

The machinery provided by the utility model formula height gauge that makes zero, comprise the main scale that vertically is arranged on the base, measuring jaw and vernier and chi frame one, the chi frame can move up and down and be arranged on the main scale, the one secondary chi with scale is set, but secondary chi is connected with reciprocating mechanism, but described reciprocating mechanism is: at main scale one screw is set, screw mandrel and secondary chi are fixedly connected, and screw mandrel is through in the screw, and screw mandrel is parallel with main scale, but described reciprocating mechanism is: at the secondary chi screwed pipe that is fixedly connected, screw mandrel passes screwed pipe, and screw mandrel is connected on the main scale by bearing or the axis hole that two ends about main scale arrange, and screw mandrel is parallel with main scale.

The utility model adopts the mechanical type height gauge, secondary chi is parallel with main scale, moving up and down under the driving mechanism drive and can move up and down, owing to be provided with scale on the secondary chi, so can be set arbitrarily in its range ability zero point, set during use secondary chi after zero point the attachable mechanical stage frame make the zero point of vernier corresponding zero point with secondary chi, as object being measured zero point, mobile measuring jaw just can directly be measured the relative height of object to the position that needs to measure, this structure has realized that with mechanical system but common cursor type height gauge Set arbitrarily when measuring or rule is measured or the reset of scribing position, the process that makes common cursor type height gauge originally just can obtain relative height by measuring absolute altitude has become only to be measured absolute altitude and gets final product, data recording and evaluation work a large amount of when measuring have been saved, effectively reduce the probability that misremembers miscalculation, simplified simultaneously checker and scriber's check line work, measuring basis is unified, effectively guaranteed the precision of measuring or ruling, this machinery formula height gauge that makes zero, price is cheaper than electronic digital display type height gauge, use and to reduce the measurer purchase cost at work, machinery makes zero the formula height gauge if there is fault simultaneously, revise easily, can also reduce measurer maintenance and repair cost, the utility model is simple in structure, easy to use, cheap, durable in use, can finish easily the measurement of absolute altitude and relative height.
