Abstract
The utility model relates to an auxiliary tool for detection, and specifically discloses a detection mandril for detecting the form and location tolerance between an internal spline and an external gear pitch cercle. The detection mandril comprises a mandril body. The gyration centers of end portions on two sides of the mandril body are provided with a central hole respectively. The surface of the mandril body is provided with a first column, a second column, a third column, a fourth column and a fifth column successively in the axial direction. The outer surface of the third column is provided with an involute external spline through machining. By adopting the detection mandril, the form and location tolerance between a finished product spline and a gear pitch cercle can be detected, and the ex factory pass rate can be improved.
Description
Technical field
The utility model relates to a kind of detection aid, specifically a kind of detection plug for detection of form and position tolerance between female spline and outer rotor pitch circle.
Background technology
At present, in some engineering machinery, mostly numerous parts is to connect to come transmitting torque with involute spline, feels relieved the coordinating of cylindrical hole and axle, and guarantees mechanically operated precision and stationarity.Some parts are wherein because reasons in structure can only be come transmitting torque and centering with spline joint, in mechanical drive, spline joint is mainly used for torsion pass, want to realize centering requirement, just must improve the machining precision of female spline, also will improve the form and position tolerance between spline and pitch circle simultaneously.Yet, deficiency due to machining precision, tolerance clearance between spline is excessive, female spline and gear form and position tolerance overproof, thereby reduced mechanically operated precision, caused the surface of contact between gear teeth face bad, stand under load is inhomogeneous, vibration in gear operation process and the generation of noise, greatly reduce product quality and serviceable life.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of detection plug, adopts this detection plug can detect the form and position tolerance of finished parts spline and pitch circle inspection, has improved ex factory pass rate.
According to the technical solution of the utility model: a kind of detection plug, comprise plug body, it is characterized in that: the described plug body both side ends centre of gyration is respectively offered a center pit, plug body surface is provided with the first cylinder, the second cylinder, the 3rd cylinder, the 4th cylinder, the 5th cylinder vertically successively, and described the 3rd cartridge outer surface is processed with involute outer spline.
As further improvement of the utility model, between described the first cylinder, the second cylinder, the 3rd cylinder, the 4th cylinder, the 5th cylinder, satisfy condition: the 3rd column diameter > the second column diameter > the 5th column diameter >=the first column diameter >=four column diameter.
As further improvement of the utility model, described the 5th cartridge outer surface is processed with anti-slip veins.
As further improvement of the utility model, described involute outer spline is axially arranged with tapering along plug body.
Technique effect of the present utility model is: the utility model is simple and reasonable for structure ingenious, on a straight-bar, process some cylinders that diameter differs, on a middle cylinder, process involute outer spline simultaneously, and this involute outer spline is processed along the axially extended tapering of plug body, so that can realize with the gapless of workpiece while detecting workpiece, coordinate; In plug body both ends of the surface, process the center pit for locating, easy to setup.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use status architecture schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
In Fig. 1, Fig. 2, comprise center pit 1, the first cylinder 2, the second cylinder 3, the 3rd cylinder 4, involute outer spline 5, the 4th cylinder 6, the 5th cylinder 7, workpiece to be checked 8, plug body 9, anti-slip veins 10 etc.
As shown in Figure 1 and Figure 2, the utility model is a kind of detection plug, comprise plug body 9, the described plug body 9 both side ends centres of gyration are respectively offered a center pit 1, plug body 9 surfaces are provided with the first cylinder 2, the second cylinder 3, the 3rd cylinder 4, the 4th cylinder 6, the 5th cylinder 7 vertically successively, and described the 3rd cylinder 4 outside surfaces are processed with involute outer spline 5.
Between described the first cylinder 2, the second cylinder 3, the 3rd cylinder 4, the 4th cylinder 6, the 5th cylinder 7, satisfy condition: the 3rd column diameter > the second column diameter > the 5th column diameter >=the first column diameter >=four column diameter.
Described the 5th cylinder 7 outside surfaces are processed with anti-slip veins 10, to facilitate hand-held taking to hold.
Described involute outer spline 5 is axially arranged with tapering along plug body 9, can closely cooperate, without sideshake for after coordinating with workpiece 8 to be checked.
The course of work of the present utility model is as follows: when the utility model is used, only workpiece 8 to be checked need be enclosed within on the 3rd cylinder 4 of plug body 9, when workpiece 8 to be checked is sheathed on plug body 9, should be noted along the taper direction of involute outer spline 5 and gradually workpiece 8 to be checked is pushed to the position that diameter is larger, until reach without sideshake between the female spline of workpiece 8 to be checked and involute outer spline 5, now plug body 9 and workpiece 8 to be checked being installed to footpath jumps on instrument, with two ends center pit 1 location, coordinating dial gauge just can detect female spline beats with the relative of pitch circle.The 3rd cylinder 4 can be jumped for detection of footpath the precision of instrument.
The utility model is simple and reasonable for structure ingenious, on a straight-bar, process some cylinders that diameter differs, on a middle cylinder, process involute outer spline simultaneously, and this involute outer spline is processed along the axially extended tapering of plug body, so that can realize with the gapless of workpiece while detecting workpiece, coordinate; In plug body both ends of the surface, process the center pit for locating, easy to setup.
