IIIdetailed description
1. Mechanical operation console section
The external dimensions of the test bench are approximately 700mm * 600mm * 500mm (length)
700mm; the connector is an L-shaped aviation connector; Width of 600mm, motor swing in the middle
Three switches can be installed simultaneously in the front and back for testing; The base is designed as a roller
The test bench has three testing stations, each of which is independent and easy to move
Control. The first two and last two components of the assembly switch are tested twice to complete the action
The experimental action is completed at that time, and the button switch is implemented using a high and low temperature cylinder (SMC),
In order to ensure the stability and reliability of the gas source during the experiment, the purchaser shall provide their own drying equipment for the gas source
Be prepared. Using Panasonic servo motor drive, it can achieve the rise and fall of different types of switches
The function of lowering and other actions can also be achieved on the panel by replacing specialized fixtures
The action functions of other button switches, the action speed and angle of the front and rear door switches
The degree can be set in the program, and aluminum profiles can be used instead of T-shaped slots.
The design of experimental equipment requires universality, and for the same functional type
Close, it is required that the equipment can be used for testing under the replacement of fixtures. For switches with the same properties
It is required to adapt to the test under flexible control and load replacement.

To ensure the accuracy of the switch action, a proximity switch is installed in the system as the mechanical origin. At the beginning of each test cycle, the system automatically returns to the origin to ensure no cumulative error.

2. Thermal insulation mechanism
Upper driving part of the test bench and lower part of the bench body
Special insulation materials are used for protection. In insurance
The temperature sensor is installed inside the temperature mechanism
The insulation system has malfunctioned, causing an internal temperature loop
When the environment exceeds the normal range, the system will automatically sound and light an alarm to remind the operator to go and handle it.
3. Fixture section

At the time of leaving the factory, Party B shall open based on the sample
Provide two sets of universal installation clips for different types of products
At the same time, provide each type of opening for Party A
Customize a set of specialized fixtures for each party. clamp
Can slide freely in the T-shaped groove of aluminum profiles
By moving and replacing the corresponding fixtures, the system can conduct tests on switches such as buttons.
4、 Test power supply and load box
Output voltage of three load power supplies: 0-60V;
Maximum current: 100A. (Considering that the load is not working simultaneously,
Change 140A to 100A to reduce costs
