Abstract

The invention discloses an eccentric spring spatial position detection device. The eccentric spring spatial position detection device comprises an eccentric spring positioning mechanism and a coordinate measurement mechanism used for measuring a two-dimensional coordinate of a spring ring of an eccentric spring. The eccentric spring positioning mechanism comprises a pair of supports, a rotating shaft, a rotating shaft driving mechanism and a pair of positioning plates, wherein the rotating shaft driving mechanism is capable of controlling rotation angles of the rotating shaft, and the positioning plates are used for positioning two ends of the eccentric spring respectively. The rotating shaft is rotatably supported on the pair of supports, and the positioning plates both sleeve the rotating shaft and are capable of rotating along with the rotating shaft. The invention further discloses a method of using the eccentric spring spatial position detection device for determining the pitch tolerance and the outer diameter tolerance of the eccentric spring, an eccentric spring detection system and an eccentric spring detection method. By the aid of the eccentric spring positioning mechanism and the coordinate measurement mechanism, the space coordinate position of the spring ring of the eccentric spring can be acquired conveniently and quickly so as to determine the pitch tolerance and the outer diameter tolerance.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to the quality inspection technology of eccentric springs. Background technique [0002] At present, the height gauge and vernier caliper are mainly used to check whether the outer diameter and pitch of the eccentric spring are qualified. This inspection method requires inspectors to measure the coils of the eccentric spring one by one, and manually adjust the measuring position of the eccentric spring, which not only reduces the inspection efficiency, but also makes it difficult to guarantee the accuracy of the inspection results. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a detection device for the spatial position of the eccentric spring that can conveniently and quickly measure the two-dimensional coordinates of the eccentric spring. [0004] Another technical problem to be solved by the present invention is to...
