Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Examples

The spline go-no-go gauge shown in fig. 1 comprises a connecting rod 10, a go-no-go gauge 20, a pressure sensor 30 and a fixing rod 40, wherein the pressure sensor 30 is positioned between the connecting rod 10 and the fixing rod 40 and fixed at the end part of the fixing rod 40, and a guide rod 50 fixed in the fixing rod is inserted into a guide hole of the connecting rod; the go-no go gauge is of an integrated structure and comprises a sleeve 21, a go gauge 22 and a no-go gauge 23, the sleeve 21 is sleeved at one end of the connecting rod 10 opposite to the pressure sensor 30, and the go gauge 22 and the no-go gauge 23 are respectively formed at two ends of the sleeve 21.

After the pitch fork to be detected is fixed, the spline go-no detection tool is driven by external power to move towards the direction of the pitch fork, and the go gauge 22 of the detection tool firstly detects.

If the go gauge 22 cannot enter the spline, the force feedback of the pressure sensor 30 is large, and the displacement distance of the equipment checking fixture judges that the spline go gauge 22 is unqualified in detection, so that the spline of the yoke is unqualified in detection.

If the go gauge 22 can smoothly enter the spline, the force feedback of the pressure sensor 30 is extremely small, and the equipment is combined with the displacement distance of the detection tool to judge that the detection of the spline go gauge 22 is qualified; then, the check tool continues to descend, and the no-go gauge 23 performs detection.

If the no-go gauge 23 can smoothly enter the spline, the force feedback of the pressure sensor 30 is extremely small, the equipment is combined with the displacement distance of the detection tool to judge that the spline no-go gauge 23 is unqualified in detection, and further judge that the spline of the yoke is unqualified in detection.

If the no-go gauge 23 cannot smoothly enter the spline, the force feedback of the pressure sensor 30 is large, the spline no-go gauge 23 is judged to be qualified by combining the displacement distance of the detection tool, and then the spline of the yoke is judged to be qualified.

Preferably, the guide slope 24 arranged at the front end of the sleeve 21 is engaged with the gauge so as to facilitate the gauge to smoothly enter the spline. Moreover, the guide inclined plane 24 can remove the burrs on the end face of the spline first, so that the burrs can be prevented from influencing the universal gauge to enter the spline.

As a modification of this embodiment, the guide rod 50 is sleeved with a spring 60, one end of the spring is connected to the fixing rod 40, the other end of the spring is connected to the connecting rod 10, and the spring 60 buffers the displacement of the connecting rod 10, so as to prevent the connecting rod 10 from impacting the pressure sensor 30 with too much force, and effectively protect the pressure sensor 30.

As a modification of this embodiment, a ring of convex rings 25 is provided in the sleeve 21, the convex rings 25 divide the inner portion of the sleeve 21 into two insertion holes, corresponding to the first insertion hole of the stop gauge 23 and the second insertion hole of the through gauge 22, the connecting rod 10 is inserted into the first insertion hole of the sleeve 21, the front end of the connecting rod 10 abuts against the convex rings 25, and a bolt 70 is inserted through the convex rings 25 from the second insertion hole and locked into the connecting rod 10 to fix the sleeve 21 to the front end of the connecting rod 10. Preferably, a backing plate is arranged between the convex ring 25 and the head of the bolt 70, the backing plate is positioned in the second inserting hole, and the head of the bolt 70 presses on the backing plate. Preferably, the cross section of the front end of the connecting rod 10 is D-shaped, a first insertion hole arranged in the sleeve 21 is matched with the front end of the connecting rod 10, and the connecting rod 10 is connected with the sleeve 21 by adopting a D-shaped structure, so that relative rotation between the go-no go gauge 20 and the connecting rod 10 can be avoided.

As a modification of this embodiment, a spacer 80 may be disposed between the connecting rod 10 and the convex ring 25, and the thickness of the spacer 80 is changed to adjust the installation distance of the go-no go gauge 20 relative to the pressure sensor 30, so as to facilitate installation and debugging of the gauge.

In conclusion, the check tool integrates the go gauge and the no-go gauge, the force feedback of the pressure sensor is used for judging whether the go gauge and the no-go gauge pass through the spline or not, the joint fork does not need to be moved, the go-and-no detection of the spline can be completed, and the detection speed of the spline is improved.
