Description
Technical field
The present invention relates to the measuring appliance of mechanical component position dimension, especially the measurer of axially bored line and cylinder axis distance.
Background technology
On some cylindrical mechanical part, have and the vertical and crossing hole of its axial line, generally control degree that their intersect with the distance of axially bored line and cylinder axis.And ordinary measring tool can not the measured hole axis and the distance of cylinder axis.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 measuring process complexity, 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 invention is to provide a kind of easy axially bored line and the measurer of cylinder axis distance, can be applied directly to the part processing scene, measure the distance of axially bored line and cylinder axis quickly and easily.
The technical solution adopted for the present invention to solve the technical problems is: be contained in the hole of measured part measuring mandrel, be pressed on the V-shaped groove of measurer measuring mandrel then, the dial gauge on the cylinder of the measured part compression measurer draws a numerical value.The cylinder of measuring part is changeed 180 ° around measuring the mandrel axis, be pressed on the V-shaped groove of measurer measuring mandrel, the dial gauge on the cylinder of the measured part compression measurer goes out a numerical value again.By two numerical value that draw are handled, just draw the distance of the axially bored line and the cylinder axis of measured part.
The measurer of axially bored line and cylinder axis distance is made up of measuring, measurement mandrel, opening sleeve, guidepost, edge of a knife gauge head, bolt and dial gauge.Concrete structure is: dial gauge is fixed by bolts in the hole of measuring top by opening sleeve, what be installed in dial gauge measurement axis front end is edge of a knife gauge head, the bus of edge of a knife gauge head front end and the axis normal of dial gauge measurement axis and all on measuring in the central plane of V-shaped groove, the axis of dial gauge measurement axis is vertical with the length direction of V-shaped groove, two guideposts are contained in the both sides of dial gauge measurement axis above the measuring symmetrically, the plane at their axis place is vertical with the V-shaped groove central plane, distance between two guideposts is less than the length of surveying the part cylinder, two guideposts are measured the mandrel axis when measuring near the plane, bus place of V-shaped groove direction ragged edges distance is greater than 0.05～0.2 millimeter of the radius of part cylinder, and the measurement mandrel is contained in the hole of tested part tightly.
This axially bored line with the advantage of the measurer of cylinder axis distance is: the Element Design that measurer is measured on demand, and manufacturing process is simple, and cost is low.Be applied to the part production scene, can measure the distance between part two upright openings easily and fast.Part processing is monitored effectively, crudy is guaranteed.

Embodiment
Accompanying drawing is a wiring layout of measuring the measurer of the axially bored line on the ratch part and cylinder axis distance in the 195 jerk pump parts, in the accompanying drawings, dial gauge (8) is fixed on bolt (7) in the hole of measuring (1) top by opening sleeve (3), and bolt (7) axis is vertical with the central plane of the mouth of opening sleeve (3).So firmly fixedly dial gauge (8) Shi Buhui makes the distortion of dial gauge (8) measurement axis and influences measuring accuracy.What be installed in dial gauge (8) measurement axis front end is edge of a knife gauge head (6), because measurand is the cylinder bus.So, use the edge of a knife gauge head (6) vertical with bus.The axis normal of the bus of edge of a knife gauge head (6) front end and dial gauge (8) measurement axis and all in measuring (1) is gone up the central plane of V-shaped groove, the axis of dial gauge (8) measurement axis is vertical with the length direction of V-shaped groove.Distance between two guideposts (5) is less than the length of surveying part (4) cylinder, two guideposts (5) near the distance of the plane, bus place of V-shaped groove direction ragged edge measurement mandrel (2) axis when measuring greater than 0.05～0.2 millimeter of the radius of part (4) cylinder.The effect of two guideposts (5) makes the axis of the cylinder of tested part (4) try one's best vertical with the axis of dial gauge (8) measurement axis when being measurement.During actual measurement, cylinder is consistent with the gap of two guideposts (5), the axis normal of cylinder axis and dial gauge (8) measurement axis then, and measurement result is the most accurate.When a guidepost (5) and cylinder do not have the gap, then another guidepost (5) is 0.2 * 2=0.4 millimeter with the maximal clearance of cylinder.Distance between general two guideposts (5) is much larger than the radius of cylinder, and above-mentioned situation also influences not quite measurement result.Can calculate according to geometric relationship: when the cylindrical radius of ratch is 3.5 millimeters, the distance between the guidepost (5) is 32 millimeters, when the maximal clearance is 0.4 millimeter.Have only 0.00027 millimeter because of the error that the axis out of plumb of cylinder axis and dial gauge (8) measurement axis causes, can ignore.Measure mandrel (2) and be contained in tightly in the hole of tested part (4), require the gap minimum.Adopt and measure mandrel (2) by 0.003 millimeter classification, the method for installing with the hole apolegamy of tested part (4) reaches.Just in the range of size in the hole of part (4), corresponding measurement mandrel (2) is all arranged,, reach the purpose of fit-up gap minimum to satisfy the apolegamy requirement by 0.003 millimeter at every interval.In order to make measurer durable in use, measure mandrel (2) heat treatment hardness 50～55HRC, edge of a knife gauge head (6) heat treatment hardness 55～60HRC of dial gauge (8), the V-shaped groove heat treatment hardness 50～55HRC of measuring (1).
The use of measurer: be contained in the hole of measured part (4) measuring mandrel (2) by apolegamy, be pressed on the V-shaped groove of measuring (1) measuring mandrel (2), the cylinder compression of measured part (4) is contained in the dial gauge (8) on the measurer (1), draws a numerical value.The cylinder of measuring part (4) is changeed 180 ° around measuring mandrel (2) axis, be pressed on the V-shaped groove of measuring (1) measuring mandrel (2), the dial gauge (8) on the cylinder compression measurer of measured part (4) goes out a numerical value again./ 2nd of an absolute value of two numerical difference between is exactly the axially bored line of measured part (4) and the distance of cylinder axis.Practical operation is: when the cylinder of the measured part first time (4) compresses the dial gauge (8) that is contained on the measurer (1), the dial plate that rotates dial gauge (8) makes pointer to " 0 ", and being compressed 1/2nd of dial gauge (8) pointer indication numerical value the second time of directly reading is exactly the axially bored line of measured part (4) and the distance of cylinder axis.
