Embodiment Construction

[0015] Such as figure 1 , figure 2 As shown, the rotary life tester of a knob potentiometer of the present invention includes a test platform 1 and a controller provided therein. The test platform 1 is provided with a positioning mechanism 3 for fixing the object under test 2. The positioning mechanism 3 A knob driving device 4 is arranged on the periphery, and the knob driving device 4 is fixed on a position-adjustable frame and is electrically connected with the controller. In this embodiment, the positioning mechanism 3 for fixing the measured object 2 is a fixing fixture, and the fixing fixture is composed of T-shaped support frames 31 distributed on the left and right. A slotted hole 312 , a fastener 314 is provided on the lower longitudinal bar 313 and is slidably connected with the slotted hole 312 . The knob driving device 4 is composed of a knob sleeve 41 and a stepping motor 42. The motor 42 has three working modes to choose from, which are 360° continuous forward...

Abstract

The invention discloses a rotation life test instrument of a knob potentiometer and is characterized in that: the instrument comprises a test platform and an embedded controller. A positioning mechanism used for fixing an object to be tested is arranged on the platform. Periphery of the positioning mechanism is arranged with a knob driving gear which is fixed on a chassis with an adjustable position and connected with the controller. The instrument can simulate hand rotation so as to test the service life of the knob potentiometer. The instrument is simple in structure, convenient and simple in operation, precise and reliable in test with good popularization value.

Description

technical field [0001] The invention relates to the technical field of detection equipment, and more specifically relates to a life detection instrument of a knob potentiometer. Background technique [0002] With the continuous development of science and technology, people's requirements for the design of audio-visual playback equipment in cars are also increasing day by day. As we all know, all electrical appliances have their inherent service life. In order to improve the quality of products, manufacturers generally use parts with longer service life for assembly and production. Under normal circumstances, after the parts are produced, they must be inspected by the equipment equipped by the manufacturer. However, in order to ensure the quality of the product, the function of the product combined with multiple parts needs to be tested. However, at present, the rotation life test of the knob on the control panel of the car audio-visual playback device is still in the manual...
