Abstract
The invention relates to a fixing device for testing the stiffness of an exhaust bellows of an automobile. The fixing device comprises a bellows fixing member and a bellows welding plate. A parallel plate at one end of the bellows fixing member is provided with open grooves, the bellows welding plate is correspondingly provided with threaded holes, and the bellows fixing member and the bellows welding plate are connected together through bolts. The other end of the bellows fixing member is provided with fine-tooth threaded holes at which the bellows fixing member is connected and fixed to an elastic element dynamic and static stiffness test machine through bolts. Two fixing devices are adopted at the same time. An exhaust bellows of an automobile can be fastened on the elastic element dynamic and static stiffness test machine. The fixing device is simple in structure and convenient in use. Test on dynamic stiffness and static stiffness of a bellows can be effectively implemented through the test machine.
Description
Technical field
The present invention relates to auto parts and components rigidity detection device, be specifically related to a kind of stationary installation of testing automobile exhaust expansion bellows rigidity.
Background technology
The sound rigidity of exhaust system corrugated tube is to determine one of exhaust system influence factor to auto NVH performance.Understand corrugated tube sound rigidity very necessary for auto exhaust NVH performance, but also do not have a kind of effective equipment corrugated tube to be carried out to the test of sound rigidity and damping at present, the sound rigidity test machine (as: MTS test machine) even if having elastic component, there is no corresponding stationary installation yet, so that be difficult to the anti-vibration performance of corrugated tube assess and compare, often to test by the mode that the automobile vibration running test after material hardness requirement and exhaust expansion bellows entrucking is detected, this process is loaded down with trivial details, lose time, cannot predict in advance corrugated tube performance situation in exploitation, R&D costs are increased, extend the construction cycle.
Summary of the invention
The object of this invention is to provide a kind of stationary installation of testing automobile exhaust expansion bellows rigidity, corrugated tube can be fixed on flexible member sound rigidity test machine (MTS test machine) by this device, thereby bellows stiffness is tested, just grasp in advance bellows stiffness situation in research and development, save cost of development and cycle.
Technical scheme of the present invention is as follows:
A stationary installation for testing automobile exhaust expansion bellows rigidity, described stationary installation symmetry is arranged on flexible member static rigidity test machine, totally two covers.Wherein, every suit all comprises corrugated tube fixture and bellows-welding plate; Described corrugated tube fixture one end arranges threaded hole, and for being bolted with flexible member sound rigidity test machine, the described corrugated tube fixture other end is horizontal flare up leveling board towards both sides, and leveling board is provided with mounting hole; The corresponding described mounting hole of described bellows-welding plate is provided with threaded hole, tightens together with corrugated tube fixture by screw bolt and nut, and bellows-welding is on bellows-welding plate.
Further, mounting hole is designed to bar hole.
Further, flexible member static rigidity test machine is MTS test machine.
And mounting hole both sides on leveling board are respectively opened to two, totally four, the threaded hole correspondence on bellows-welding plate also has four, can increase like this reliability of installation.
When test, corrugated tube is arranged on the upper of flexible member static rigidity test machine by above-mentioned stationary installation, the quiet rigidity that test machine stretches by vertical direction and the mode compressed is tested corrugated tube, by test the dynamic stiffness of corrugated tube perpendicular to the mode of porpoise, so just can realize the test to auto exhaust bellows stiffness.
The present invention is connected and fixed the stationary installation of exhaust expansion bellows on flexible member sound rigidity test machine by providing, and has realized the dynamic and static rigidity of entrucking front exhaust corrugated tube and has tested in advance, has saved exhaust expansion bellows cost of development, has shortened its construction cycle; And fix by corrugated tube fixture one end and flexible member sound rigidity test machine, other end both sides leveling board grooved bore, pass on the slotted eye that bellows-welding plate is fixed on corrugated tube fixture by bolt, realize corrugated tube static state, dynamic rate is tested in advance, this is simple in structure, functional reliability is high, and good endurance is simultaneously with low cost.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As Fig. 1 to 5 shows, the stationary installation of testing automobile exhaust expansion bellows rigidity comprises corrugated tube fixture 2 and bellows-welding plate 4, each a set of the upper of flexible member static rigidity test machine that be arranged on respectively, one end of corrugated tube fixture 2 is provided with threaded hole 7, for fixing with the upper and lower two ends of flexible member sound rigidity test machine, described corrugated tube fixture 2 other ends are horizontal flare up leveling board towards both sides, and the mounting hole 8 of two bar shapeds is respectively opened on leveling board both sides, totally four.Four mounting holes on the corresponding leveling board of bellows-welding plate 4 are provided with four threaded holes 9, connected bellows-welding plate is tightened together with corrugated tube fixture by screw bolt and nut 3.Pad 6 is set between nut 3 and leveling board.Bellows-welding plate is together with bellows-welding.
When test, adopt MTS test machine 10, corrugated tube is arranged between MTS test machine 10 upper by above-mentioned stationary installation, the quiet rigidity that the mode this test machine being stretched by vertical direction and compress is tested corrugated tube, by the dynamic stiffness of testing corrugated tube perpendicular to the mode of Fig. 1 in-plane porpoise, so just can realize the test to auto exhaust bellows stiffness.
