Description
Technical Field
The utility model belongs to the technical field of spring detectors, and particularly relates to a spring rotation angle detection jig.
Background
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 produced therefore requires measuring the angle between the two straight torsion arms at the end of the spring to determine if the torsion spring is acceptable.
The existing detection jig needs to fix the torsion arm at one side of the spring to be detected by purely manual operation, the torsion arm at one fixed side cannot be guaranteed to be parallel to the 0-degree scale mark, measurement errors can be caused, and time and labor are consumed for manually fixing the torsion arm; the diameter of the existing positioning column for positioning the spring to be detected is fixed, so that the positioning requirement of the spring to be detected with different diameters cannot be met; therefore, the present utility model provides a spring rotation angle detection jig to solve the above-mentioned problems.
