Abstract
The utility model provides a checking tool for an included angle between a gullet center and a notch tooth center of a steering gear shaft. The checking tool is characterized in that: the tool has a supporting seat; a left tip is fixedly arranged at the left side of the supporting seat; a right tip seat is arranged at the right side of the supporting seat and a right tip is slidably arranged on the right tip seat; a fan-shaped spline sleeve having an inner spline is slidably arranged on the right tip seat; a positioning column is arranged on the supporting seat; two ends of a steering gear shaft are respectively pressed against the left tip and the right tip; the upper end of the positioning column is pressed against between gullet of the steering gear shaft; the inner spline of the spline sleeve is sleevedly arranged outside of the spline of the steering gear shaft; a measurement meter is fixedly arranged on the supporting seat, wherein the needle pointer is pressed against the side surface of the spline sleeve. According to the utility model, cooperation between the spline sleeve and the spline of the steering gear shaft is utilized to enable a corresponding relation between an angle value of the side surface of the spline sleeve and the included angle between a gullet center and a notch tooth center of a special steering gear shaft to be generated; therefore, the included angle between the gullet center and the notch tooth center of the special steering gear shaft can be obtained only by measuring the angle value of the side surface of the spline sleeve, so that measurement is convenient and accurate.
Description
Technical field
The utility model belongs to mechanical inspection machine, relates in particular to the inspection machine that a kind of parameter of teeth groove center and hypodontia center angle of the tooth sector axle that automotive transmission is used detects.
Background technology
The teeth groove center of the tooth sector axle of automotive transmission and hypodontia center angle are important parameters of tooth sector axle, and the tooth sector axle of finished product must check this parameter to guarantee that it is qualified.At present, the check of parameter all is a hand test hereto, does not have special cubing, and checkability is low.
The utility model content
The utility model provides a kind of teeth groove center of tooth sector axle and the cubing of hypodontia center angle, and its purpose solves the shortcoming that prior art exists, and provides a kind of and can make things convenient for the teeth groove center of checking the tooth sector axle exactly and the cubing of hypodontia center angle.
The utility model solves the technical scheme that its technical matters adopted:
The cubing of a kind of teeth groove center of tooth sector axle and hypodontia center angle; It is characterized in that: have bearing; The bearing left side is installed with left top, and the bearing right side is provided with right dead head, and sliding on the right dead head, it is right top to be provided with; Slide on the right dead head and be provided with fan-shaped spline housing, also be provided with reference column on the bearing with female spline; Tooth sector axle two ends are pushed up to a left side top and right top respectively, and the reference column upper end is resisted against between the teeth groove of tooth sector axle, and the inner spline housing of above-mentioned spline housing is located at outside the spline of tooth sector axle; Be installed with the survey table on the bearing, survey the side that list index is resisted against spline housing.
The usefulness of technique scheme is:
The utility model utilizes the angle value that cooperates the side that makes spline housing and the hypodontia center of special gear shaft and the angle generation corresponding relation at teeth groove center of spline housing and the spline of tooth sector axle; As long as the side angle value of measuring spline housing just can be known the teeth groove center and the hypodontia center angle of tooth sector axle, convenient measurement is accurate.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the utility model diagrammatic cross-section;
Fig. 2 is the A-A diagrammatic cross-section of Fig. 1.
Embodiment
Left and right in the utility model only is for convenience, do not constitute the restriction to the utility model technical scheme.
Like Fig. 1, shown in Figure 2; The utlity model has bearing 1, bearing 1 left side is installed with left center sleeve 2, and left center sleeve 2 internal fixation are arranged with a left side top 21; The right side 22 that left side center sleeve 2 has a convexity, the length of right side 22 matches with the step body 31 that the left end of standard component 3 has.
Bearing 1 right side is provided with right dead head 4, slides on the right dead head 4 that it is right top 5 to be provided with, have spring 51 tops be against right top 5 and right dead head 4 between, right top 5 ends that are positioned at outside the right dead head 4 are connected with pull bar 52.Pull bar 52 can draw the right side top 5 to the right, and spring 61 can make right top 5 to reset left.
Slide on the right dead head 4 and be provided with the fan-shaped spline housing 6 with female spline 61, spline housing 6 is provided with pin-and-hole 62, and the straight pin 63 that is installed on the right dead head 4 penetrates in the pin-and-hole 62, and the cooperation of straight pin 63 and pin-and-hole 62 makes spline housing 6 obtain basic location.Spline housing 6 also has spline housing handle 64.
Be installed with survey table 7 on the bearing 1, the pointer top of survey table 7 is against on the side 60 of spline housing 6.
Also be provided with reference column 8 on the bearing 1; Reference column 8 is set in the column base 81 of location; Having spring 84 is resisted against bearing 18 effects is that location column base 81 is fixed by the screws 82 in some through holes 83 that are located on the bearing 1, also promptly unclamps screw 82 with reference column 8 top upwards with reference column; The position of location column base 8 can be adjusted; Just reference column 8 also can be adjusted the position, and lock-screw 82 again, and the position of reference column 8 is fixed.
During use; Draw back pull bar 52 earlier; With standard component 3 supporting a left side top 21 (with spline 33 hypodontia places up, with reference column 8 withstand on standard component 3 32 of teeth groove), slowly put back to the top again and go up right top 5; The right side 22 of convexity of step end face and left center sleeve 2 that guarantees teeth groove 32 parts of standard component 3 is adjacent to, and stirs spline housing handle 64 then gently the female spline 61 of spline housing 6 is set on the spline 33 of standard component 3; Knock location column base 81 gently, running fix post 8, the mobile meeting of reference column 8 drives standard component 3 and rotates, and rotates the pin-and-hole 61 that makes spline housing 6 through spline 33 drive spline housings 6 and tries one's best coaxial with straight pin 6.Tight screwing 82, the position of stationary positioned post 8.The pointer top of survey table 7 is against on the side 60 of spline housing 6, swings spline housing 6 more gently, reads maximal value and minimum value, obtains mean value, and mean value is that zero-bit makes zero survey table 7 then.Then standard component 3 is taken off; After changing tooth sector axle clamping to be measured and putting in place; Swing spline housing 6 gently; Record numerical value: the mean value of reading maximal value and minimum value, this mean value converts through the formula that obtains according to each accessory size parameter, has just obtained the teeth groove center of tooth sector axle and the numerical value of hypodontia center angle.
