Abstract
The utility model discloses a rotating type double measuring range micrometer. The utility model is mainly characterized in that a rotating measuring block movably connected with a positioning revolution shaft positioned at the shaft line position is arranged on a distal end of a fixed measuring arm on the basis of the existing traditional outside micrometer and the conjoint position is provided with s positioning flange. Both ends of the rotating measuring block are provided with a long and a short fixed measuring heads. A double-range number of division is also arranged on a movable measuring bar on the external side of the movable measuring arm. The utility model has the advantages of reasonable design, precise structure, easy process and manufacture, convenient operation and use, high reliability, firm connection, facile conversion, precise measuring, visual reading, etc.
Description
The utility model relates to a kind of measurer to use mechanical measuring means to carry out linear dimension meterings such as length, thickness as feature, especially a kind of swinging double-range milscale.
Present widely used measurement length micrometer only has the range ability of a finite length usually.For linear measure longimetry on a large scale, often need different size, the many of different ranges select milscale to measure, and this results in hand cramps the effect that influence is measured obviously for the person of manipulating.Chinese patent CN2125811U has proposed a kind of " outside micrometer that has extension bar ", and its primary structure feature is that the fixedly gauge head end at conventional milscale is provided with an extension bar, and extension bar docks with this fixation side head by a connector.This outside micrometer has increased the measurement range of a class by the access of extension bar, but because it only is the linearity prolongation of carrying out extension bar from fixing this point of gauge head, Gu its junction is stable inadequately, firm, the swing of extension bar and rotation in addition brings influence for measuring reliability and accuracy.And the scale numerical value in its reading district is not made corresponding modification and is handled, and when utilizing extension bar to measure, can not directly obtain reading accurately, need convert, so it is also very inconvenient in manipulating process.
The purpose of this utility model will overcome existing weak point in the above-mentioned prior art exactly, proposes a kind of reasonable in design, of a tightly knit structure, processing and manufacturing is easy, manipulates easyly, reliable, connects firmly, it is convenient to change, and measures accurately the direct swinging double-range of reading milscale.
The purpose of this utility model can reach by implementing following technical proposal: on the basis of existing conventional outside micrometer, in the measurement piece that circles round that the setting of fixation measuring arm far-end is flexibly connected by the location revolving shaft that is in its axial location, its junction is provided with locating flange.The described two ends of measuring piece of circling round are respectively equipped with long fixation measuring head and short fixation measuring head.Described location revolving shaft can be selected bolt, so that get loose with fastening; On above-mentioned locating flange, also can set up trip bolt, to strengthen fastening effect; Be positioned on the movement measuring staff in the movable gage beam outside and also the double-range number of division can be set, help intuitively reading measurement data.
Accompanying drawing is the structural representation of the utility model embodiment.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.Measure piece 3 in conventional outside micrometer fixation measuring arm 1 far-end setting by circling round of bolt 2 connections that are positioned at this fixation measuring arm 1 axis place, its two ends are equipped with long fixation measuring head 4 and short fixation measuring head 5 respectively, and this measurement piece 3 that circles round can be axle rotation, positioning by above-mentioned bolt 2.The described junction of measuring piece 3 and fixation measuring arm 1 of circling round is provided with locating flange 6, and it is provided with trip bolt 7.Be with the scale cover 11 of band double-range number of division 10 on the movement measuring staff 9 in movable gage beam 8 outsides, this double-range number of division 10 corresponds respectively to the long and short fixation measuring head 4 and 5 on the measurement piece 3 that circles round.When using the utility model product, only need determine selected range ability, with corresponding long and short fixation measuring head 4 or 5 supportingly just can measure relative with movement measuring staff 9 according to the size of measured workpiece.Also only need directly read when obtaining measurement data from corresponding double-range number of division 10 on the scale cover 11.
The utility model has reasonable in designly, of a tightly knit structure compared with prior art, and processing and manufacturing is easy, Operate easy to usely, reliable, connect firmly, it is convenient change, measure accurate, the characteristics such as reading is direct, available Substitute traditional outside micrometer.
