Description

A kind of inner cone gradient steel ball is measured cubing

Technical field

The utility model relates to a kind of measurement mechanism, particularly a kind of for measuring the measurement mechanism of workpiece inner cone gradient.

Background technology

At present, traditional inner cone natural measurement of tilt method has: (1) is coated with color method: taper plug gauge is coated to red lead powder, then match with tested inner cone, according to its contacted area ratio, judge that whether gradient is qualified; This method requires the gauger to have certain experiences, and can not know the actual value of inner cone gradient; (2) tool microscope is measured: the ratio that calculates the large and small end section difference in diameter of tapering and large and small end section distance by measurement converses the tapering amount of taper, and the method cost is too high, also more complicated, is not suitable at the workshop in-site measurement.

Publication number is that utility model patent that CN201047746Y, utility model name are called " a kind of internal taper detector " discloses a kind of internal taper and measures cubing, but this device also has the following disadvantages: 1, measuring accuracy is not high, because gauge head is to consist of sharp angle on housing and the outer nose circle of fuse, from microcosmic, sharp angle is irregular circular arc, and after repeatedly using, it is large that the sharp angle circular arc becomes, make measuring error increase, separately, because gauge head is that sharp angle contacts with inclined-plane, can not also affect measuring accuracy by automatic capturing .2, this kind of detector is only suitable for minor diameter inner cone natural measurement of tilt, because housing and fuse can not be done too greatly, so large diameter inner cone natural measurement of tilt is not suitable for.

Summary of the invention

The purpose of this utility model is to provide a kind of a kind of inner cone gradient steel ball that can be used for testing anchor slab or intermediate plate internal taper hole inner cone gradient to measure cubing, this cubing can be measured the inner cone gradient fast, accurately in production scene, and can bring very big facility to the lathe adjustment, avoid the gradient dimension overproof to cause product defective in batches.

The technical scheme addressed the above problem is: a kind of inner cone gradient steel ball is measured cubing, comprises dial gauge, matching used standard taper ring gauge, it is characterized in that, this inner cone gradient steel ball is measured cubing and is also comprised gasket ring, large and small spheric probe, gland nut, hollow bolt, fixture block;

Described gasket ring is the middle right cylinder that center pit is arranged;

Described large and small spheric probe for middle have through hole, take the centre of sphere as symmetrical billiard table;

Large spheric probe is enclosed within on the dial gauge clamping sleeve and by gasket ring, gland nut, hollow bolt and the screw be enclosed within on the dial gauge clamping sleeve and is fixed on dial gauge clamping sleeve upper end; The pellet shapes gauge head is enclosed within on the movable measuring staff of dial gauge and by fixture block, screw and is fixed on the movable measuring staff of dial gauge, can move up and down with the movable measuring staff of dial gauge;

Under align mode, inner cone gradient steel ball is measured cubing integral body and is placed in the standard taper ring gauge, and large spheric probe contacts with standard taper ring gauge upper end is inner, and the pellet shapes gauge head contacts with standard taper ring gauge lower end is inner;

Under measuring state, inner cone gradient steel ball is measured cubing integral body and is placed in the measured piece inside with the inner cone gradient, and large spheric probe contacts with the measured piece upper end with the inner cone gradient is inner, and the pellet shapes gauge head contacts with the measured piece lower end is inner.

Owing to taking said structure, a kind of inner cone gradient steel ball of the utility model is measured cubing and is had following beneficial effect:

1. improved work efficiency and the accuracy of detection of measuring measured piece inner cone gradient:

Within the utility model, cone gradient steel ball is measured cubing and is demonstrated the variate-value of standard taper ring gauge 8 and the distance of measured piece 9 between large spheric probe 31 and pellet shapes gauge head 32 with the inner cone gradient by the dial gauge on end casing, just can converse measured workpiece (as anchor slab or the intermediate plate of working) the inner cone gradient of internal taper hole and the variable quantity of standard taper ring gauge gradient; So just complicated natural measurement of tilt is converted into to simple linear measure longimetry; Avoided the operator repeatedly to come and go universal tool-measuring microscope and measured the inner cone gradient, improved work efficiency and improved measuring accuracy.

2. the inner cone gradient shows by dial gauge, and amount of taper is simple and clear, is convenient to the adjustment of lathe, avoids the generation of unacceptable product in batches, has guaranteed product quality, has reduced production cost.

3. within the utility model, the measuring principle of cone gradient steel ball measurement cubing is indirectly to measure the sine principle of inner cone gradient according to two spheres, its spheric probe adopts high-accuracy steel ball billiard table to make, in measuring process, be inner cone gradient steel ball to be measured to cubing integral body is placed in the standard taper ring gauge or with measured piece 9 inside of inner cone gradient, large spheric probe 31 contacts with standard taper ring gauge or measured piece 9 inside, upper ends, and pellet shapes gauge head 32 contacts with standard taper ring gauge or measured piece 9 inside, lower ends;

By the dial gauge on gasket ring compare standard taper ring gauge 8 at the distance L 1 between large spheric probe 31 and pellet shapes gauge head 32 and measured piece 9 with the inner cone gradient at the variate-value △ L of the distance L 2 between spheric probe 31 and pellet shapes gauge head 32 greatly, converse the variable quantity of measured piece inner cone gradient and standard taper ring gauge gradient, thereby measure the outer cone gradient α of measured piece;

Because the arc surface that is spheric probe contacts with the tapering inclined-plane, this cubing can overlap with tested inner cone center line by automatic capturing, because the circular arc precision of spheric probe is high, make any contact point all meet sine formula, and the Application standard taper ring-ga(u)ge is calibrated the zero-bit of this cubing, this is the main cause that this cubing can improve measuring accuracy, therefore this inner cone gradient steel ball cubing measurement inner cone gradient has indicating value accurately and reliably, light and handy durable advantage, be particularly suitable for the measurement in production scene, this cubing is by selecting suitable spheric probe or selecting the dial gauge of large stroke, can enlarge this cubing and measure the scope of inner cone gradient.
