Problems solved by technology

At present, the performance and life tests of rotary switches, such as dimmer switches, speed control switches, gear-type air-conditioning fans, and rotary-adjustable thermostats need to test several indicators, while in the past testing fields required multiple different The equipment is measured, especially for the rotary switch of the motor load, which requires instantaneous switching of 6 times current / 1 times current and 9 times current / 6 times current, which requires coordination between the equipment and the load, which increases the complexity of the device

Abstract

The invention discloses a multifunctional rotary switch tester, which comprises a machine frame, a test bed, a display screen, an input device, a control system and a load, wherein, the test bed comprises a plurality of test units; each test unit is provided with a switch fixture which is correspondingly provided with a stepper motor and a switch rotating shaft grip holder which is driven to rotate by the stepper motor; the control system comprises a controller, a motor driver, a counter, a sampling circuit and a temperature controller; control software is arranged inside the controller; the display screen ,the input device, various stepper motors and the load are accessed into the control system. The tester of the invention is a device which integrates a plurality of test functions like service life test, temperature rise test, on-off capacity test and so on into a whole and completely improves the defects of the prior tester which are respectively bulkiness, non-tunable detect, small capacity, inconvenient assembly, high cost and so on.

Description

technical field [0001] The invention relates to a switch device testing device, in particular to a multifunctional rotary switch testing machine. Background technique [0002] Switch testing machine is a machine used to test the performance and life of electrical switches. At present, the performance and life tests of rotary switches, such as dimmer switches, speed control switches, gear-type air-conditioning fans, and rotary-adjustable thermostats need to test several indicators, while in the past testing fields required multiple different The equipment is measured, especially for the rotary switch of the motor load, which requires instantaneous switching of 6 times current / 1 times current and 9 times current / 6 times current, which requires coordination between the equipment and the load, which increases the complexity of the device. Contents of the invention [0003] The invention provides a test for rotation durability, normal operation and on-off capability of a rota...
