Embodiment 1

[0015] Example 1: as Figure 1-4 As shown, a pin fatigue testing machine includes a base 8, and the base 8 is provided with an air filter 5, a flow controller 2, a reversing control valve 3, a two-way solenoid valve 4, and a two-way air cylinder 7 connected in sequence. The reversing control valve 3 and the two-way solenoid valve 4 on the air circuit are controlled by the program controller 1, the two-way air cylinder 7 is fixed on the base 8, and its output rod is connected to the base a9 by the plug-in fitting In the static connector 10, the base 8 is also provided with a movable connector 11 facing the static connector 10. The movable connector 11 is fixed on the movable connector base 13 through the connector mounting base b12. Above, the movable plug base 13 is fixed on the base 8 .

[0016] The air cleaner 5 and the program controller 1 are arranged on the upright column fixed on the base 8 .

Abstract

The invention discloses a pin fatigue testing machine which comprises a substrate. A gas circuit formed by sequentially connecting an air filter, a flow controller, a reversing control valve, a two-way solenoid valve and a two-way air cylinder is arranged on the substrate, the reversing control valve and the two-way solenoid valve on the gas circuit are controlled by a programming controller, the two-way air cylinder is fixed to the substrate, the output rod of the two-way air cylinder is provided with a static connector clip through a connector clip mounting base a, a movable connector clip base right opposite to the static connector clip is further arranged on the substrate and is fixed to the substrate through a connector clip mounting base b. The pin fatigue testing machine has the advantages that different on-off numbers of times can be set through the programming controller to simulate frequency of butt joint required by design so as to verify whether reliability and quality control of a pin are effective or not.

Description

technical field [0001] The invention relates to the technical field of testing machines for fatigue testing, in particular to a pin fatigue testing machine. Background technique [0002] There is a key part in the electrical system of the high-speed EMU and the automatic electrical connector of the urban subway called the pin, which plays the role of completing the electrical connection when the electrical connector is working. The stability of the pins is very critical to the entire electrical connector and the electrical system it is connected to. Therefore, the quality requirements are very high, and it must undergo strict fatigue tests before use, and there can be no mistakes. [0003] But since this part is a new part, its shape and size are not suitable for those existing fatigue testing machines. Therefore, it is necessary to develop a pin fatigue testing machine, which is specially used for the fatigue test of the pin. SUMMARY OF THE INVENTION [0004] The purpos...
