Abstract

The invention provides a system for testing the service life of a special straight reciprocating motion mechanism. The system is characterized by comprising a microcontroller module, wherein the microcontroller module drives a straight reciprocating motion mechanism through a motion mechanism drive module, a motion mechanism monitoring module is used for detecting the motion state of the straight reciprocating motion mechanism and feeding back a signal to the microcontroller module, the microcontroller module is interacted with the outside through a human-machine interface module, and a power supply module is used for respectively supplying power to the motion mechanism drive module, the motion mechanism monitoring module and the microcontroller module. The system for testing the service life of the special straight reciprocating motion mechanism, disclosed by the invention, has the advantages that a simple and reliable mature design and a redundant design are selected for a circuit; the strong current part and the weak current part in a circuit system are subjected to necessary separation by using a separator, and thus the continuous and stable operation of a complete machine of the system is ensured; and a motion mechanism out-of-control scram protection and remote alarm device is designed, thus the straight reciprocating motion mechanism is protected from being damaged because of being out of control, and the reliability of such a straight motion mechanism service life tester is fully ensured.

Description

technical field [0001] The invention relates to a life testing system of a linear reciprocating mechanism, belonging to the technical field of measuring equipment. Background technique [0002] In high-tech fields such as aerospace, the application of special motion mechanisms is very extensive. Due to the special nature of these fields, this type of motion mechanism must complete specific complex operations continuously and reliably, which is very demanding on the motion properties of the motion mechanism. On the premise of satisfying specific operations, from the perspective of reliability, the service life of special motion mechanisms is also an important factor that needs to be considered emphatically. Therefore, the life test of special motion mechanism is also a problem worthy of in-depth consideration. The special motion mechanism usually uses a special motor, so it has an unconventional motion mode, and its life test is also of high complexity. [0003] Linear mot...
