Embodiment 1

[0032] Embodiment 1. The door body hinge durability detection device of this embodiment uses a manipulator to simulate a human hand to open and close the door body to detect the durability of the door body hinge. It consists of a motor for joint movement and a controller for controlling the operation of the motor. As a preferred design solution of this embodiment, the motor preferably uses a servo motor to drive and control each movable joint of the manipulator, and one servo motor controls the movement of one movable joint. The controller can use a programmable logic controller PLC to drive and control the servo motor, the servo motor drives the mechanical arm to rotate through the reducer, and uses the combined motion of multiple servo motors to fit the running track of the front end of the mechanical arm. The trajectory coincides with the actual running trajectory of the tested door body, so that the working condition of the door hinge under real conditions can be simulated...

Abstract

The invention discloses a door body hinge durability detection method and an apparatus thereof. The apparatus comprises: a manipulator, motors and a controller. The manipulator comprises a plurality of movable joints. The each movable joint is driven to move by the independent motor. A front end of a robotic arm is connected with the door body to be detected. The controller controls a plurality of motors to perform combination motion so as to further drive the front end of the robotic arm to simulate an actual moving track of the door body to open and close the door body to be detected. In the invention, a motion process of a human hand can be simulated. An actual working state and a stress state of the door body hinge can be really reflected. A working efficiency and accuracy of detection are high. After remodeling a design every time or improving a material, a household electric enterprise needs to carry out a life test of a household electrical appliance. By using the detection apparatus of the invention, real and effective data of household electrical appliance door body hinge durability detection can be provided for the household electric enterprise or a related mechanism. Therefore, research and development and sizing periods of a new product can be shortened.

Description

technical field [0001] The invention belongs to the technical field of equipment detection, and in particular relates to a method and a device for automatically detecting the durability of door hinges. Background technique [0002] With the development of social economy and the improvement of people's living standards, the social ownership of home appliances is also increasing, and the replacement is getting faster and faster, and users' requirements for the quality of home appliances are becoming more and more stringent. [0003] In most of the existing home appliances, such as refrigerators, freezers, washing machines, microwave ovens, etc., the opening and closing of the door body is accomplished by hinges. After a period of use of this kind of household appliances with a door, the hinges will be worn out. In the light case, the door body will be slightly displaced and eccentrically worn, resulting in the problem of poor sealing; in severe cases, it may even cause The fa...
