Abstract
Disclosed is a coattail slot caliber rule, composed of a main scale and a vice caliber rule. According to the graduations of a trigonometric function figure, the width dimension and the height dimension of the upper and the lower parts of the coattail lead rail can be readout at the same time through the fact that the measure is carried out by the caliber rule. The measure can be carried out in any position in the height direction of a coattail, the width dimension of the upper part of the coattail leadi rail can be readout. Consequently, in the process of prosessing, the measuring can be carried out when the processing is carried out at the same time to achieve controlling the width dimension of the coattail lead rail. In addition, the caliber rule can be used as a slide rule to get the relative dimension of the coattail.
Description
A kind of dovetail slide calliper rule promptly are used to measure the survey instrument of dovetail processing dimension, belong to metering and field tests.
At present, lathe manufacturing and overhaul producer when measuring dovetail guide, adopt the dovetail model more or survey piece, cooperate slide calliper rule to measure, and perhaps make 55 ° of angle block gauges and are installed on the slide calliper rule pawl and measure.But, no matter be existing any survey instrument, all belong to the final measurement of workpiece, promptly can't in process, measure at any time and process be controlled.
The purpose of this utility model is to provide a kind of improved special-purpose dovetail guide to measure slide calliper rule.It can be processed on the limit in process, and the limit is measured, and when measuring on any position of dovetail short transverse, all can obtain dovetail guide upper width size; When processing ended inspection dovetail size, one-shot measurement can obtain the height dimension H of dovetail, top and the bottom width dimensions L1 and L2.
The following principle that is based on the utility model realizes.
By trigonometric function as can be known, one fixedly acute angle be that two right-angle sides have functional relation in 55 ° the right-angle triangle.At the base angle is in the isosceles triangle of α, if be that the boundary is divided into two right-angle triangles to isosceles triangle with the base center line, and removes with horizontal direction, then, again a line, base is done in two right-angle triangle summits and also does a line.This just forms a dovetail guide shape.If the base of these two right-angle triangles=0.5, α=55 °, then opposite side=tg55 ° * 0.5=0.714 ... so, the base of isosceles triangle=1, high=0.714, the groove foundation of Here it is dovetail slide calliper rule, if the base increases simultaneously with height or dwindles n times, its ratio is constant.Like this, when measuring dovetail guide, horizontal slide calliper rule (being called main scale) can be combined with vertical slide calliper rule (being called attached chi).Main scale is in order to measure the top and the bottom width dimensions of dovetail guide, and its two measuring jaw end faces are made 55 ° of angular shapes.Its attached chi is in order to measure the height of dovetail guide.Attached chi scale has the corresponding numerical value of two row, and delegation is by common metric system length scale, and its reflects the variation of dovetail guide height dimension, and another row is pressed trigonometric function rule scale, and its numerical value is relevant with the dovetail groove angle, the variation of its reflection dovetail Width size.
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.
Fig. 1 a is interior dovetail slide calliper rule.
Fig. 1 b is outer dovetail slide calliper rule.
In Fig. 1 a, (1) is main scale, and (2) are attached chi, and the main scale body is vertical mutually with attached blade, and the two is equipped with vernier.Attached chi (2) chi of squaring up itself, try square bottom (5) is a measuring basis.There is scale (3) on attached chi right side, and it presses metric system long measure scale, and there is scale (4) in its left side, and it presses tangent trigonometric function value scale.The scale of main scale (1) and scale (4) are corresponding one by one, are 1 as the main scale scale promptly, and then scale (4) is tg α/2, and α is the dovetail groove angle, and as α=55 °, then its value is 0.714.(6) be the main scale measuring jaw, its end angle is identical with the dovetail groove angle, and present embodiment is 55 °.Certainly, also can be by dovetail groove angle difference, and make other special-purpose dovetail slide calliper rule.
During measurement, benchmark (5) is leaned against on the reference field of tested dovetail, measure the width L2 of dovetail, read the dovetail height dimension, numerical value L2 is deducted reading on the scale (4), promptly try to achieve dovetail upper width size L1 from scale (3) with main scale.If what measure is outer dovetail, then numerical value L2 is added high scale (4) reading, promptly try to achieve dovetail upper width size L1.Because scale (4) reflection is funtcional relationship, so the location independent of the numerical value of L1 and measuring claw (6) is measured on arbitrary position, can try to achieve dovetail upper width size.Measuring jaw (6) can be used as dovetail groove angle processing model.In addition, this dovetail slide calliper rule also can be used as the use of dovetail slipstick.Owing on the drawing dovetail size is often only marked top or lower width size, and another width dimensions needs to calculate, and uses these slide calliper rule,, can read another width dimensions as long as corresponding size one is drawn.
Claims (4)
1, a kind of dovetail slide calliper rule is characterized in that it comprises a main scale [1] and an attached chi [2] of measuring the dovetail height dimension of measuring the dovetail width dimensions, and main scale [1] blade is vertical mutually with attached chi [2] blade.
2, dovetail slide calliper rule as claimed in claim 1 is characterized in that attached chi (2) has scale (3) and the corresponding mutually scale of (4) two row, and two row scale units are respectively metric system long measure and tangent trigonometric function value tg α/2, and α is the dovetail groove angle.
3, dovetail slide calliper rule as claimed in claim 1 is characterized in that the angle [alpha] of measuring claw (6) of main scale (1) is identical with the dovetail groove angle.
4,, it is characterized in that α can be 55 ° of angles as claim 1,2,3 described dovetail slide calliper rule.
