Abstract

The invention discloses a simple and effective spring detection tool. The tool comprises a bracket and a fixed shaft arranged on the bracket, wherein a spring is arranged between an automobile trunk cover and an automobile frame; a fixed disc and a rotary disc are installed on the fixed shaft, the center line of the fixed disc coincides with the axis of the fixed shaft, the center line of the rotary disc inclines to the axis of the fixed shaft, and the rotary disc is connected to the fixed shaft in a pivoted mode. The fixed disc is provided with a hinge seat capable of rotating around the fixed disc in the circumferential direction, the rotating disc is provided with a hinge piece, the front end of the spring is hinged to the hinge seat, and the rear end of the spring is hinged to the hinge piece. When the rotating disc is rotated, the distance between the hinge piece and the hinge base is changed, and the spring is in a stretched or compressed state, and moreover, the included angle between the spring and the fixed shaft is changed. When the spring detection jig detects the spring, the actual use condition of the spring is simulated so as to judge whether the spring has abnormal sound or not.

Description

technical field [0001] The invention relates to testing equipment for auto parts. Background technique [0002] Car trunk lid, flip up, open, flip down, close. The trunk lid is hinged on the vehicle frame, and a spring is arranged between the vehicle frame and the trunk lid. When the trunk lid is flipped up or down, the springs experience expansion and contraction. Unqualified springs will make abnormal noises when the trunk is turned up or down, which will affect the quality of the car. After long-term use, the springs may fail. Contents of the invention [0003] The technical problem solved by the invention is to detect whether there is any abnormal sound in the spring between the trunk lid and the vehicle frame of the automobile. [0004] In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: a simple and effective spring detection fixture, including a bracket and a fixed shaft installed on the brac...
