The invention relates to a shift lever switch service life detection device comprising a frame bottom plate, a frame top plate, a driving device, a driving shaft, shift forks and push rods. The framebottom plate and the frame top plate form a double-layer three-dimensional installation frame structure; the driving shaft is driven to rotate by the driving device; the frame bottom plate is providedwith a driving bottom plate, the position of which can be adjusted in the length direction; the driving shaft is installed on the driving bottom plate in parallel; the driving shaft is axially and uniformly provided with a plurality of driving wheels in a spaced manner; the double sides of each driving wheel are provided with a first cam block and a second cam block; the shift forks are symmetrically arranged on the two sides of the driving wheels; the middle portions of the shift forks are fixed in a rotating shaft manner and the lower ends of the shift forks are connected with resetting springs; the lower ends of the shift forks swing in a reciprocating manner by means of push of the first cam blocks or the second cam blocks and the upper ends push the push rods to make horizontal reciprocating telescopic movement to push shift levers of shift lever switches. The shift lever switch service life detection device can detect the service life of a shift lever switch automatically with high efficiency and is suitable for shift lever switches of different types.
Description
technical field [0001] The invention belongs to the technical field of service life detection of a lever switch, in particular to a device for detecting the service life of a lever switch. Background technique [0002] The lever switch is a switch that turns the circuit on or off by turning the lever, which can achieve the purpose of switching the circuit. Because the lever switch has the characteristics of flexible opening and closing, stable and reliable performance, it has been widely used in various electronic products such as various instruments / instrument equipment, electric toys, fax machines, audio equipment, medical equipment, and beauty equipment. [0003] The service life is one of the performance indicators that the lever switch must possess, therefore, it becomes very necessary to detect the service life of the lever switch. However, under the normal use environment, the service life of the lever switch is relatively long, so it is labor-intensive to detect the...
