Abstract
The invention relates to an auxiliary tool for detecting, in particular to a detection core rod for detecting the form and location tolerance between an internal spline and an external gear pitch circle. The detection core rod comprises a core rod body, the rotation centers of the two side end portions of the core rod body are respectively provided with a center hole, a first column body, a second column body, a third column body, a fourth column body and a fifth column body are sequentially arranged on the surface of the core rod body in the axial direction, and an involution external spline is machined on the outer surface of the third column body. By means of the detection core rod, the form and location tolerance between a finished spline and a gear pitch circle can be detected, and the ex-factory pass rate is improved.
Description
Technical field
The present invention 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 present invention is directed to the problems referred to above, a kind of detection plug is provided, adopt this detection plug can detect the form and position tolerance of finished parts spline and pitch circle inspection, improved ex factory pass rate.
According to technical scheme of the present invention: 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 a further improvement on the present invention, 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 a further improvement on the present invention, described the 5th cartridge outer surface is processed with anti-slip veins.
As a further improvement on the present invention, described involute outer spline is axially arranged with tapering along plug body.
Technique effect of the present invention is: the present invention 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 invention.
Fig. 2 is use status architecture schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention 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 present invention 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 invention is as follows: when the present invention uses, 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, coordinate dial gauge just can detect female spline and beat with the relative of pitch circle.The 3rd cylinder 4 can be jumped for detection of footpath the precision of instrument.
The present invention 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.
