Description

Auxiliary fixture capable of simply and conveniently testing torsion spring angle

Technical Field

The utility model relates to the field of physics, in particular to a design measurement technology, and specifically relates to an auxiliary tool capable of simply and conveniently testing the angle of a torsion spring.

Background

The torsion spring is also called a torsion spring, is a mechanical part which works by utilizing elasticity, is a complex design principle in all spring types, and has quite active type change, so the theory involved in design is most complicated. The torsion spring belongs to a coil spring. The ends of the torsion springs are secured to other components which pull them back to their original position as they rotate about the spring center, creating a torque or rotational force. Torsion springs can store and release angular energy or statically secure a device by rotating the arm about the central axis of the spring body. Such springs are typically close-fitting, but have a pitch between coils to reduce friction. They create resistance to rotation or external forces of rotation. The direction of rotation (clockwise or counterclockwise) of the torsion spring is designed to determine the direction of rotation of the spring, depending on the application requirements. The turns are either tightly wrapped or split wrapped, allowing for torsional loading (at right angles to the spring axis). The end of the spring may be wound into a hook or straight torsion arm.

The torsion spring angle is the value of the included angle of the rotating arms at the two ends of the torsion spring in the radial plane of the torsion spring. Torsion spring angle is an important parameter of torsion springs, which need to be measured in product design applications. In the prior art, the torsion spring angle measurement is required to be measured by using a three-coordinate measurement technology or by using a projector through auxiliary fixture positioning, which is time-consuming and labor-consuming and inconvenient.
