5. Structure and performance
The test machine is composed of main engine, operation control system, measurement and display system, test fixture and safety protection device.
(1)Host machine part
It adopts big base and wide and thick double support frame structure. The frame base is cast in one piece, the upper part of the double support body is cast connected, the reducer is installed and the frame is cast in one piece. The whole machine is a rigid whole, which has high stability after natural aging and artificial aging treatment. The whole machining, there is no assembly error between the base of the frame, which ensures that the distance between the axis of the pendulum and the strike center is accurate. When the anvil block is impacted, the original split main opportunity will affect the impact measurement accuracy due to the elastic deformation of bolt joint and energy absorption. The vertical column is symmetrical, and the main shaft of the pendulum is supported by a simple beam, which can effectively avoid the lateral vibration when the pendulum hits and reduce the impact on the test results.
(2) Operational control system
The operation is controlled by Siemens PLC, through double-speed reducer and electromagnetic clutch lifting hammer. Test, the first by microcomputer interface or touch screen, click on take place, the PLC instruction driving clutch, gear motor startup absorption, drive the pendulum counterclockwise rotation, arrived at predetermined Angle, the PLC instruction motor stops, the clutch disengaged, hang on pendulum swing device, automatic safety pin, that is ready for the shock. After the sample is placed, first click the repulse pin and the safety pin will be returned. Then click the shock, pull the electromagnet to push the hook out quickly, and the pendulum will fall freely in the clockwise direction. Sample after thrust, pendulum using the surplus energy back to positive peak, electromagnetic clutch and PLC instructions, motor start, counterclockwise drive the pendulum rises again, arrived at predetermined Angle, the PLC instruction motor stops, the clutch disengaged, hang on pendulum swing device, automatic safety pin, namely impact to complete a cycle, and ready for the next impact. After the impact of the sample is completed, the fractured sample falls on the recovery belt, and the qualified or unqualified samples are sent to different recovery devices respectively according to the preset criterion.
The system has strong anti-interference ability, stable operation, safe and reliable.
(3)Measurement display system
1. Dial display: after the impact is completed, the impact energy value can be directly read through the pointer of the dial, but the accuracy is low.
2. Microcomputer measuring operation showed that the pendulum pendulum shaft end connection installation accuracy, photoelectric encoder is used to accurately test after the pendulum rising Yang Angle and impact pendulum of Yang Angle, can automatically identify Yang Angle and Yang Angle, its level of output pulse number and pendulum Yang is directly proportional to the Angle or the Yang Angle, Angle test precision can reach 0.06 ° Angle resolution can reach 0.015 °.Through signal processing and calculation, the microcomputer gets the accurate impact energy value.
The software design has automatic calibration function, which can test the bearing friction energy loss, pointer friction energy loss and air resistance energy loss. It can automatically subtract the existing friction energy loss and air resistance loss from the calculation results, making the test results more accurate.
