Abstract
The present invention discloses a circle jumping measuring implement of an end surface corresponding to a reference hole, which is composed of a fixed measuring head, a bracket, a spindle, a dial indicator, etc., wherein the dial indicator is fixed on the spindle through the bracket, and the fixed measuring head is installed on the position which is symmetrical with the measuring head of the dial indicator on the other side of the bracket which is fixed with the dial indicator. A reference hole of a part which needs to be measured is perpendicular to the horizontal surface, and a measured surface is upward, the spindle is inserted into the reference hole, the fixed measuring head and the measuring head of the dial indicator synchronously point to the measured surface, the spindle is rotated by 360 DEG, the difference between a minimum point and a maximal point, which is displayed on the dial indicator is treated, and then, the circle jumping value of the measured surface corresponding to the reference hole can be obtained. The measuring implement of the present invention has the advantages of simple and easy measurement and low measurement cost. The measuring frequency for parts can be enlarged, and the present invention is favorable for improving product quality.
Description
Affiliated technical field
The present invention relates to the measuring appliance of mechanical component position of related features, especially end face is to the measuring appliance of benchmark circle pulsation.
Background technology
Some mechanical component end face will be used three-coordinates measuring machine to the measurement of benchmark circle pulsation now, and the price of three-coordinates measuring machine is higher at present, and measurement expense is also high.General midget plant should be have more than is needed.Another kind method is: the part that survey be supported on make its datum hole vertical on the flat board with surface level, survey towards last.Select to be mated the very little mandrel in gap according to the physical size of datum hole, on axle, adorn a dial gauge by support.Dull and stereotyped and axle bottom center hole between put a suitable steel ball after being contained in the datum hole to axle, this moment, the gauge head of dial gauge can refer at the appropriate location and the dial gauge of tested surface suitable range is arranged.Mandrel 360 degree are handled the minimum point of dial gauge demonstration and the difference of peak, just can draw the round jitter values of tested surface to datum hole.Whole process is cumbersome.Should use for the above-mentioned two kinds of measuring methods of the big part of complex structure quality especially and all compare difficulty.
Summary of the invention
The purpose of this invention is to provide a kind of easy end face to the benchmark circle pulsation measuring tool, make measurement convenient and swift.
The objective of the invention is to realize as follows: measurer is by fixedly gauge head, support, mandrel, dial gauge are formed.Dial gauge is fixed on the mandrel by support, at the fixing opposite side of dial gauge of support, installs and fixes gauge head with the dial gauge gauge head for the position of mandrel axis symmetry.Mandrel should be able to be free to slide and rotate in datum hole φ, and tolerance clearance is pressed H8/g6.
During measurement, make the datum hole that to measure part vertical substantially with surface level, tested towards last, mandrel is inserted in the datum hole, fixedly gauge head and dial gauge gauge head refer to simultaneously on tested face, rotation mandrel's 360 degree just can draw the round jitter values of tested surface to datum hole by the minimum point of dial gauge demonstration and the difference of peak are handled.Because this measurer is relative measurement, the less gap of mandrel and datum hole does not influence measuring accuracy under the effect of gravity.So needn't match mandrel when measuring, make measuring process simple and easy to do, measurement expense is low.Can strengthen the measurement frequency, help the raising of product quality part.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing 2 is cut-open views that accompanying drawing 1 prolongs B-B.Accompanying drawing 1 is that the A of accompanying drawing 2 is to view.
Embodiment
With reference to accompanying drawing 1, accompanying drawing 2, its endoporus of support 5 usefulness and bolt 1 are fixed on the upper end of mandrel 6, and dial gauge 7 is contained in support 5 grooved bore corresponding with it, 2 are fixed by tighting a bolt.Fixedly gauge head 3 is contained in the other end of support 5, in the threaded hole of dial gauge hole for mandrel axis symmetry, is fixed in position with nut 4.Mandrel 6 should be able to be free to slide and rotate in datum hole φ, and H8/g6 is pressed in its gap.During measurement, make the datum hole φ that will measure part 8 vertical substantially with surface level, tested face M upwards, mandrel is inserted among the datum hole φ, fixedly the gauge head of gauge head 3 and dial gauge 7 refers to simultaneously on tested face M, rotates measurer 360 degree, draws the minimum point of dial gauge 7 demonstrations and the difference h of peak.Under the situation that the shape error of tested surface is ignored, according to geometrical principle: whole measurer moves up and down with the fixing position of gauge head contact point under the effect of its gravity, this amount of movement is exactly the round jitter values that face M goes up this point, since the gauge head of dial gauge with fixing gauge head for the position of mandrel axis symmetry, so the value h that dial gauge shows is 2 times of this null circle jitter values.Because of the gauge head contact point is not the maximum cylindrical of plane M, so tested surface M is for roundness error b=h ÷ 2 ÷ d * D of datum hole φ.
