Description

Technical Field

[0001] The utility model relates to the field of spring quality inspection, in particular to a spring tension and compression testing machine. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. The tension of the spring is also called elastic force. After an object is deformed by an external force, if the external force is removed, the object can return to its original shape. Its direction is opposite to the direction of the external force that causes the object to deform.

[0003] After searching, the Chinese patent announcement number is CN216978303U, which discloses a spring tension and compression test device. The patent controls the position of the spring by installing an open tubular placement seat on the upper surface of the pressure measuring disk. There are certain problems with this device: the open tubular placement seat is of fixed size and cannot adapt to springs of different sizes. Utility Model Content
