Spring detection device and method

The invention relates to the dimension detection field, and specifically discloses a spring detection device and method; the left end on the top surface of a detection platform is provided with a length stop plate; the right end on the top surface of the detection platform is provided with a length upper limit end face and a length lower limit end face; a diameter stop plate is arranged between the length stop plate and the length lower limit end face; a diameter measuring table is arranged in front of the diameter stop plate; one side of the diameter measuring table is provided with a diameter lower limit end face and a diameter upper limit end face. The spring is horizontally placed in detection, and naturally stretches; one end of the spring leans on the length stop plate, the position of the other end of the spring is checked, or the side face of the spring makes contact with the front side face of the diameter stop plate, and the position of the other side of the spring is checked. The spring detection d
