Tractor hood opening and closing reliability testing device

Abstract

The invention discloses a tractor hood opening and closing reliability testing device, which comprises a rack assembly, a tractor hood opening mechanism assembly, a tractor hood closing mechanism assembly and an opening force balance bracket assembly. The tractor hood opening assembly is assembled at an upper left longitudinal beam, an upper right longitudinal beam and a front upper crossbeam in the rack assembly; the tractor hood closing assembly is assembled at a left middle longitudinal beam, a right middle longitudinal beam and a middle front crossbeam in the rack assembly; and the openingforce balance bracket assembly and the rack assembly are connected through fasteners. By adopting a complete set of mechanical overturning mechanism, the whole process actions of a driver opening andclosing a tractor hood are truly simulated; because of consistency and high efficiency of the mechanical actions, the verification quality of a tractor hood opening and closing reliability test is improved, the verification cycle is shortened, and the labor cost and labor intensity of verification personnel are lowered; and an overall rack structure has the large adjustment margin, thus the universalization requirement of prototypes of different boundary dimensions is met through input of one set of equipment, and the practical and economic requirements of testing equipment input are met.

Description

technical field [0001] The invention belongs to the field of tractor test equipment, and relates to a tractor hood opening and closing reliability test device. Background technique [0002] In recent years, the technical level of tractor products, which are an important part of my country's agricultural machinery, has been rapidly improved. When a new product comes out, its main components need to undergo strict indoor and outdoor tests, one of which is the hood opening and closing reliability test. For the verification of tractor hood opening and closing reliability indicators, based on the requirements of test standards, the test methods are mostly used in a controllable test site, and tens of thousands of hood opening and closing actions are performed on the front hood of the tractor to simulate the hood. The workload situation in the whole product life cycle. Afterwards, according to the status of the test piece after the verification, analyze whether there is any fail...

Problems solved by technology

[0003] At present, the reliability verification method of tractor hood turning mechanism in China generally adopts on-site operators to manually count and turn over on the spot. The test method is backward, the operation efficiency is low, the verification condition is not consistent, the labor intensity is high, and the test process is not sufficient, which often leads to the lag of the test conclusion. Insufficient evaluation of the reliability indicators of the hood products, which in turn affects the overall quality and launch cycle of new tractor products
