Embodiment Construction

[0014] The automobile accelerator pedal durability testing machine of the present invention is composed of three parts: a temperature and humidity test box, a mechanical transmission device, and a measurement and control system. Outline structure shown in Figure 1.

[0015] Described temperature-humidity test chamber 7 can adopt existing temperature-humidity test chamber (such as PHC1704-D II type temperature-humidity test chamber) on the market to carry out transformation (side wall is opened 100mm hole, installs main rotating shaft) after forming. The characteristics of the test box are: temperature range: -70 ~ 150 ℃, accuracy ± 2k. Humidity range: 20~98%, accuracy ±3%. It is easy to operate, and adopts a color LCD touch screen with Chinese interface, which can set and display various operating data. The recording volume is large, and a large amount of sampling data can be recorded in real time, and a CF (standard flash memory card) memory card can be used to print curves...

Abstract

The invention discloses a durability testing machine for an automotive accelerator pedal, which comprises a temperature and humidity test chamber, a mechanical transmission device and a test and control system, wherein the mechanical transmission device comprises a mechanical portion and a power portion; the mechanical portion is arranged in the temperature and humidity test chamber and is driven by the power portion; the mechanical portion includes a support, a main rotation shaft arranged on the upper end of the support, a salve rotation shaft arranged on the lower end of the support, and a parallel connection rod arranged on the main rotation shaft and the slave rotation shaft; a plurality of rockers with rollers are respectively arranged on the main rotation shaft and the slave rotation shaft; the test and control system is divided into a control system and a test system; the control system adopts PLC for transmitting program and sending a switcher instruction to control a stem motor to rotate; and an angle encoder is used for detecting the steering position of the rotation shaft. The invention can drive FPM to move back and forth under a certain environment condition to detect the durability of the FPM.

Description

technical field [0001] The invention relates to a test and detection device for auto parts, in particular to a test machine for the durability of an automobile accelerator pedal. Background technique [0002] At present, the production of auto parts in China is developing rapidly, and auto parts have high requirements for product reliability. Some experimental equipment is urgently needed to test and verify the reliability of products. Automobile accelerator pedal durability testing machine is one of them. [0003] Since the durability test of the automobile accelerator pedal is a composite test of multiple working conditions, system integration is required. Limited by the volume of the test box, it is necessary to design the rocker arm transmission system. There are many types of samples for testing and testing, and various working conditions are required. It is necessary to design a variety of fixtures, such as ordinary fixtures, tilting fixtures, limiting moment fixtures...
