Description
Technical field
The utility model is related to mechanical measurement field, more particularly, to a kind of cg outer annular diameter of the constant velocity cardan joint of automobile and
Roundness measuring instrument.
Background technology
Constant velocity cardan joint is that a kind of two misaligned axles of axis couple together, and so that two axles is passed with identical angular speed
Pass the device of motion.Constant velocity cardan joint is widely used, complex structure, technique are accurate, with high content of technology, and have compact conformation,
Lightweight, driving torque is big, transmission is steady, the low excellent properties of noise.The appearance of constant velocity cardan joint, has promoted front wheel driving significantly
Electrical automobile and the development of all-wheel drive vehicle.At present, in the world the power transmission of most automobiles all using constant velocity cardan joint,
And cg outer shroud product is a very important part in CV joint for car.Cg outer shroud needs and cg inner ring and axostylus axostyle etc. zero
Part cooperation assembling, current cg outer shroud is mainly machined by lathe, car system.The product specification of cg outer shroud directly affects universal joint
Whether constant speed, and underproof cg outer shroud will lead to running car unstable, vehicle is shaken, vibration, and speed changer back axle is included
Power transmission shaft all has compared with major injury, unstable wear.
The method of existing detection circularity mainly has revolution method of principal axes, line-of-sight course, two-point method, sciagraphy and coordinate method.Gyroaxis
Method: revolve one-turn formed Circular test (preferable circle) using the axle in precision bearing system and compare with measured circle, on two radius of circles
Difference is converted to electric signal by electricity formula linear transducer, is indicated by display instrument after calculating through processing of circuit and electronic computer
Go out deviation from circular from, or measured circle contour pattern is gone out by recorder trace.Line-of-sight course: often measured workpiece is placed in v shape block and carries out
Measurement, during measurement, makes measured workpiece revolve one-turn in v shape block, reads maximum indicating value and minimum indicating value, two indicating values from micrometer
The half of difference is the cylindrical deviation from circular from of measured workpiece.This method is applied to measurement and has the cylindrical or interior of odd number seamed edge form error
Circle, conventional 2 α angles are 90 °, two pieces of v shape blocks of 120 ° or 72 °, 108 ° measure respectively.When being measured using line-of-sight course, two fixing
The conventional v shape block of support replaces, and because v shape block and measured workpiece are that face contacts, therefore reduces certainty of measurement.Two-point method: conventional thousand points
Chi, comparator etc. measure, using on a certain section of measured circle between each diameter maximum difference half as this section deviation from circular from.This
Method is suitable to measure the cylindrical or inner circle with even number seamed edge form error.Sciagraphy: often measure on projecting apparatus, by measured circle
Contour image is compared with two limit concentric circles being plotted on projection screen, thus obtaining the deviation from circular from of measured piece.This method is suitable for
There is the miniature workpiece at blade shape edge in measurement.Coordinate method: general survey on the three coordinate measuring machine with electronic computer
Amount.If the rectangular coordinate system by being pre-selected measures coordinate value x, the y doing on measured circle, institute is pressed by electronic computer
The Circularity error evaluation method selecting calculates the deviation from circular from of measured circle.
The size to measured piece that above measuring method has or shape require, the lacking due to measuring method itself having
Fall into, lead to certainty of measurement inaccurate.The survey tool such as conventional digital display calliper and micrometer, has the disadvantage that digital display calliper,
Measuring speed is slow, and measuring result error is big；, there is measuring speed slowly, pendulous frequency is many, cumbersome in micrometer.
In view of drawbacks described above, the utility model creator passes through long research and practice obtains this creation finally.
