Durability test system and high-efficiency consistency test method for electrical appliance sockets

Abstract

The invention discloses a durability test system and a high-efficiency consistency test method for electrical appliance sockets used for household and similar purposes. The system consists of an upper computer control device, a lower computer control device and a stepping motor execution operating device, wherein a stepping motor actuator replaces the conventional pneumatic rod actuator, and the disadvantages that the pneumatic rod actuator has heavy operation and maintenance workload and high cost are eliminated. Three-dimensional clamp numerical control positioning has the advantages of continuous testing without interruption, precise positioning and high test result consistency. The test under the control of a corrected elevator speed analogue quantity is implemented referring to an elevator speed curve, wherein the test comprises speed open-loop control of a non-plug sub-stroke and displacement closed-loop control of a plug sub-stroke; the whole process of the corrected elevator speed test does not have acceleration transilience, so that both the test efficiency and the test precision are taken into consideration; in addition, the probability that test equipment is damaged by a rigid mechanical transmission pair of a stepping motor is stopped by the displacement closed-loop control of the plug sub-stroke.

Description

technical field [0001] The invention relates to the technical field of durability testing of household and similar electrical appliances, in particular to a durability testing system and a high-efficiency consistency testing method for household and similar electrical sockets. Background technique [0002] As a basic circuit connection device, household and similar electrical sockets are an indispensable electrical accessory product in work and life. An effective test system and test method is one of the key supporting technologies to ensure the quality of the socket. The quality of the socket is directly related to the reliable use of the connected electrical appliances and the personal safety of the user. The durability index of electrical sockets is the product technical index specified in the national mandatory standards; the connotation of durability refers to the working period of the product without failure (or without maintenance), which is used to characterize the u...
