Abstract

Provided is a simple and convenient coaxiality measuring tool. A dial indicator is fixed on a clamping disc. The clamping disc is fixed above an expansible mandrel which is installed in basic holes of a tested component. Three groups of equant radial holes are disposed above and below a cooperating portion of the expansible mandrel and the hole of the tested component. A slot flat end set screw, a spring, and a steel ball are installed in each hole. Under the action of the springs, one fifth of the balls are exposed outside a cylindrical surface of the expansible mandrel. A measuring head of the dial indicator is pressed on a surface of a tested hole. A measuring head axial lead of the dial indicator is vertical and intersects with an axial lead of the expansible mandrel. The coaxiality measuring tool is advantaged in that when the expansible mandrel rotates a circle, a variation in value indicated by the dial indicator of the clamping disc is circle run-out quantity of the hole relative to the hole where the expansible mandrel is in. A whole measuring process is simple and reliable, and manufacturing cost of the measuring tool is low.

Description

The right alignment measurer
Affiliated technical field
The utility model relates to the measuring appliance of mechanical component position of related features, especially the right alignment measurer.
Background technology
The hole of some mechanical component is to the measurement of circle pulsation now, and the best way is to use three-coordinates measuring machine, and measurement result is accurate.But the environment for use of three-coordinates measuring machine is strict, and tested part must be taken the special-purpose place of three-coordinates measuring machine and measure, for complex structure, and the part that quality is big, measurement is got up cumbersome, the measurement expense height.The price of three-coordinates measuring machine is higher at present, and general midget plant should be have more than is needed, more can not be applied to the operation scene.
Summary of the invention
The purpose of this utility model provides a kind of easy right alignment measurer, can be applied directly to the part processing scene, measures convenient and swiftly, accomplishes part is monitored effectively, and crudy is guaranteed.
The purpose of this utility model realizes as follows: dial gauge is fixed on the clamping disk(-sc), clamping disk(-sc) is fixed on the top of expansible mandrel, the bottom and upper segment of the mating part of the datum hole of expansible mandrel and tested part has the radial hole of three groups of five equilibriums, fluting flush end holding screw, spring and steel ball are contained in each hole, under the effect of spring, / 5th of a spheroid can expose the periphery of expansible mandrel, the expansible mandrel is contained in the datum hole of tested part, the gauge head of dial gauge is pressed in the measured hole surface, and the gauge head axial line of dial gauge is vertical with expansible mandrel axial line and crossing.
The advantage of this right alignment measurer is: the expansible mandrel rotates a circle, and the numerical value change amount of the dial gauge indication of clamping disk(-sc) is exactly that this hole is to the circular runout in the hole at expansible mandrel place.Whole measuring process is simple and reliable, the measurer low cost of manufacture.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the front view of right alignment measurer.
Accompanying drawing 2 is cut-open views that accompanying drawing 1 prolongs A-A.
Among the figure: 1. tested part, 2. clamping disk(-sc), 3. dial gauge, 4. expansible mandrel, 5. steel ball, 6. spring, 7. fluting flush end holding screw.
Embodiment
With reference to accompanying drawing, the right alignment measurer comprises clamping disk(-sc) (2), dial gauge (3), expansible mandrel (4), steel ball (5), spring (6) and fluting flush end holding screw (7).Dial gauge (3) is fixed on the clamping disk(-sc) (2) with method commonly used, and clamping disk(-sc) (2) is fixed on the top of expansible mandrel (4).Because the physical size of the datum hole of tested part (1) changes, can not satisfy the measurement needs with single mandrel in margin tolerance.The bottom and upper segment of the mating part in the hole of expansible mandrel (4) and tested part (1) has the radial hole of three groups of five equilibriums, fluting flush end holding screw (7), spring (6) and steel ball (5) are contained in each hole, under the effect of spring (5), / 5th of a spheroid can expose the periphery of expansible mandrel (4), and the gauge head of dial gauge (3) is pressed in the surface of the measured hole of tested part.Expansible mandrel (4) is contained in the datum hole of tested part (1), and like this, expansible mandrel (4) just can be got rid of the gap with the datum hole of tested part, and the axis that expansible mandrel (4) rotates the datum hole that just can represent tested part rotates.The gauge head axial line of dial gauge (3) is vertical with expansible mandrel (4) axial line and crossing.The numeral of dial gauge (3) indication is exactly that the measured hole of tested part is to the coaxiality error value of the datum hole of tested part.

Claims (1)

1. right alignment measurer: it comprises clamping disk(-sc), dial gauge, the expansible mandrel, steel ball, spring and fluting flush end holding screw, it is characterized in that: dial gauge is fixed on the clamping disk(-sc), clamping disk(-sc) is fixed on the top of expansible mandrel, the bottom and upper segment of the mating part of the datum hole of expansible mandrel and tested part has the radial hole of three groups of five equilibriums, fluting flush end holding screw, spring and steel ball are contained in each hole, under the effect of spring, / 5th of a spheroid can expose the periphery of expansible mandrel, the expansible mandrel is contained in the datum hole of tested part, the gauge head of dial gauge is pressed in the measured hole surface, and the gauge head axial line of dial gauge is vertical with expansible mandrel axial line and crossing.
