AI Technical Summary

Technical Problem

In the existing technology, the perpendicularity detection of curved springs is prone to large errors due to curvature errors, and the test piece is difficult to clamp or is not clamped stably, which affects the detection accuracy.

Method used

The device employs a clamping base design on a support base, and through the adjustment mechanism of positioning pins and arc grooves, combined with an angle sensor, it can realize the perpendicularity detection of the test piece in both standard and natural states. The width and hardness of the groove are adjusted using magnetorheological fluid to ensure detection accuracy.

Benefits of technology

It improves the accuracy and efficiency of perpendicularity detection of curved springs, avoids misjudgment and unstable clamping, and is adaptable to the detection of test pieces with different curvatures.

Abstract

The application relates to the spring detection technical field, and particularly discloses an arc-shaped spring end face perpendicularity detection device and a detection method, which comprises a supporting seat, a clamping seat is rotationally arranged on the supporting seat, an arc-shaped groove is formed in the clamping seat, a positioning pin is arranged at one end of the inner bottom wall of the arc-shaped groove, an angle sensor is arranged on the supporting seat, the angle sensor is located on the rotating path of the clamping seat, one end of the arc-shaped groove close to the positioning pin is matched with a standard part, the groove width of the arc-shaped groove gradually increases from one end of the positioning pin to the other end of the positioning pin, and an adjusting mechanism for adjusting the groove width of the arc-shaped groove is arranged on the clamping seat. The groove width of the arc-shaped groove is adjusted through the adjusting mechanism, the to-be-detected part is clamped in the free state and the standard state, and the perpendicularity effect in the two states is detected respectively.
