Description
Technical field
The utility model belongs to cubing technical field, more particularly to a kind of inspection of motor turning power screw boss symmetry
Tool.
Background technology
In motor turning machine production field, the power screw of steering machine scratches groove must be symmetrical, just can guarantee that steering force degree
Unanimously, if the groove symmetry of scratching of power screw exceedes certain limit, cause left-right rotation dynamics inconsistent, urgent feelings occur
Easily there is traffic accident because steering dynamics is inconsistent during condition.Therefore after power screw is machined, it is necessary to power spiral shell
Bar is detected.
First that boss is parallel with base plate when detecting that power screw scratches groove, then recycle lever table measures power spiral shell
Bar scratches the symmetry of groove.Therefore, ensure that boss is symmetrical first before the symmetry that groove is scratched in measurement power screw, therefore, surveying
Amount power screw is measured to boss symmetry first before scratching the symmetry of groove.The detection utensil of boss symmetry is detected at present
Mainly include platform and the lifting platform positioned at platform side, first ride on platform boss side during detection, then adjustment rises
Drop platform, makes the cylinder at boss rear be the level of state, and the cylindrical sides top height at boss rear is then measured with lever meter
Degree, then overturns power screw, the another side of boss is located on platform, and the cylindrical sides top at boss rear is measured again
The height in portion, two height value differences are the symmetry of boss.
There is following defect in above-mentioned measuring instrument and method：First, during lifting platform is adjusted, after easily causing boss
The cylinder of side is inclined, and thus increases the error of measurement, causes accuracy of measurement poor；Second, detection time is long, detection one
Individual workpiece probably needs 130 seconds or so, considerably increases production cost；Third, due to adding positioned at power screw opposite side screw thread
The influence of work technique, the thread depth of screw rod opposite side is inconsistent after overturning the screw thread of front screw side and overturning, and causes upset
The cylinder run-off the straight at front boss rear so that measurement error is further increased, influences the accuracy of detection.
Utility model content
Problem to be solved in the utility model is just to provide that a kind of used time is few, high, production line of saving production cost, the degree of accuracy
More smooth motor turning power screw boss symmetry degree gauge.
To solve the above problems, the technical side that the utility model motor turning power screw boss symmetry degree gauge is used
Case is：Including the lever meter with measurement axle, also including base, the side of the base is provided with strip groove, the bar
The width of connected in star is equal to the width of the boss of motor vehicle electronic-controlled power steering power screw, and the strip groove side is provided with thick stick
Bar table fixed seat, measurement shaft through-hole is provided with the lever meter fixed seat, the measurement shaft through-hole and the strip groove
Central axis upright, in the measurement axle insertion measurement shaft through-hole, is provided with vertical logical above the measurement shaft through-hole
Hole, jackscrew is provided with the vertical through holes.
Motor turning power screw boss symmetry degree gauge provided by the utility model compared with prior art, has
Advantages below：First, due to including the lever meter with measurement axle, also including base, bar being provided with the side of the base
Connected in star, the width of the strip groove is equal to the width of the boss of motor vehicle electronic-controlled power steering power screw, recessed in the bar shaped
Groove side is provided with lever meter fixed seat, and measurement shaft through-hole is provided with the lever meter fixed seat, the measurement shaft through-hole with
The central axis upright of the strip groove, in the measurement axle insertion measurement shaft through-hole, on the measurement shaft through-hole
Side is provided with vertical through holes, jackscrew is provided with the vertical through holes, before measuring, first according to square cylinder after boss
Diameter, jackscrew is unclamped, position of the adjustment measurement axle in measurement shaft through-hole, is then tightened jackscrew, by power screw
Side with boss downwards, boss is stuck in strip groove, pulls power screw along the direction of strip groove, now boss
The cylindrical sides touching measurement axle top of top, lever meter reads data, horizontally rotates power screw 180 degree, makes boss
Opposite side is pressed close to measure axle, and power screw is moved along strip groove, reads the numerical value on lever meter, and the difference of two values is just
It is the symmetry of boss, so, measurement is more accurate, and time of measuring is shorter, one workpiece of measurement is only needed to 15 seconds, is substantially reduced
Human cost.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model motor turning power screw boss symmetry degree gauge；
Fig. 2 is the structural representation for inserting the motor turning power screw boss symmetry degree gauge after power screw.
Specific embodiment
The utility model motor turning power screw boss symmetry is examined with reference to the accompanying drawings and detailed description
The structure and use principle of tool are described in further details.
As depicted in figs. 1 and 2, the structural representation of the utility model motor turning power screw boss symmetry degree gauge
Figure, the utility model motor turning power screw boss symmetry degree gauge includes the lever meter 2 with measurement axle 1, also includes
Base 3, strip groove 4 is provided with the side of base 3, and the width of strip groove 4 is equal to motor vehicle electronic-controlled power steering power screw 5
Boss 6 width, the side of strip groove 4 is provided with lever meter fixed seat 7, measurement is provided with lever meter fixed seat 7
Shaft through-hole 8, the measurement shaft through-hole 8 and the central axis upright of strip groove 4, in the measurement insertion measurement shaft through-hole 8 of axle 1, are surveying
Vertical through holes 9 are provided with above amount shaft through-hole 8, jackscrew 10 is provided with vertical through holes 9.Before measuring, first according to convex
The diameter of square cylinder 11 after platform 6, jackscrew 10 is unclamped, position of the adjustment measurement axle 1 in measurement shaft through-hole 8, then
Jackscrew 10 is tightened, by side of the power screw 5 with boss 6 downwards, boss 6 is stuck in strip groove 4, along strip groove
4 direction pulls power screw 5, now the side of the cylinder 11 touching measurement axle top of the top of boss 6, and lever meter reads number
According to, horizontally rotate power screw 180 degree, make the opposite side of boss press close to measure axle, and power screw is moved along strip groove,
The numerical value on lever meter is read, the difference of two values is exactly the symmetry of boss, so, measurement is more accurate, and time of measuring is more
Short, one workpiece of measurement is only needed to 15 seconds, greatly reduces human cost.
Protection domain of the present utility model is not limited solely to above-described embodiment, as long as structure and the utility model motor vehicle
Steering power screw rod boss symmetry degree gauge structure is identical, just falls in the scope of the utility model protection.
