Abstract
The invention relates to a fixing device for measurement of rigidity of an automobile emission lifting lug. The fixing device for the measurement of the rigidity of the automobile emission lifting lug comprises a lifting lug sleeve and a lifting lug bolt. A threaded hole is formed in one end of the lifting lug sleeve and used for being fixed with an elastic component dynamic and static rigidity test machine. Parallel forfication pieces are arranged at the other end of the lifting lug sleeve and provided with notches with side openings. The lifting lug bolt penetrates through a lifting lug perforation and is arranged on the notches with the side openings of the parallel forfication pieces. Bosses and threads are arranged at two ends of the lifting lug bolt. Clamping nuts are screwed at the two ends of the lifting lug bolt and enable the parallel forfication pieces to be clamped and fixed on the clamping nuts and the bosses. The fixing device is capable of enabling the automobile emission lifting lug to be tightly fixed on the elastic component dynamic and static rigidity test machine, simple in structure and convenient to use. According to the elastic component dynamic and static rigidity test machine, tests for lifting lug static rigidity and lifting dynamic rigidity can be effectively achieved.
Description
Technical field
The present invention relates to the auto parts and components rigidity detection device, be specifically related to a kind of stationary installation of testing automobile exhaust lifting lug rigidity.
Background technology
The sound rigidity of lifting lug of exhaust system is to determine that exhaust system is to one of influence factor of auto NVH performance.understand hanger sound rigidity very necessary for auto exhaust NVH performance, but also do not have a kind of effective equipment hanger to be carried out the test of sound rigidity and damping at present, the sound rigidity test machine (as: MTS test machine) even have elastic component, there is no corresponding stationary installation yet, so that be difficult to the anti-vibration performance of hanger is assessed and compared, often to test by the mode that the automobile vibration running test after material hardness requirement and exhaust lifting lug entrucking is detected, this process is loaded down with trivial details, lose time, can't predict in advance hanger performance situation in exploitation, R﹠D costs have been increased, extended the construction cycle.
Summary of the invention
The stationary installation that the purpose of this invention is to provide a kind of testing automobile exhaust lifting lug rigidity, hanger can be fixed on flexible member sound rigidity test machine (MTS test machine) by this device, thereby hanger rigidity is tested, just grasp in advance hanger rigidity situation in research and development, save cost of development, shorten the construction cycle.
The stationary installation of testing automobile exhaust lifting lug rigidity disclosed by the invention, comprise hanger sleeve, ear stud, described hanger sleeve one end arranges threaded hole and is used for fixing with flexible member sound rigidity test machine, the described hanger sleeve other end is parallel bifurcated sheet, and described parallel bifurcated sheet is provided with the side otch; Ear stud passes hanger perforation and frame on the side otch of parallel bifurcated sheet; The ear stud two ends arrange convex and screw thread, and ear stud two ends screw the chucking nut parallel bifurcated sheet is fixedly clamped on chucking nut and convex.
Further, between chucking nut and parallel bifurcated sheet, pad is set;
Further, flexible member static rigidity test machine is the MTS test machine.
Beneficial effect of the present invention is: provide a kind of exhaust lifting lug that is connected and fixed in the stationary installation of flexible member sound rigidity test machine, realized that the dynamic and static rigidity of entrucking front exhaust hanger tests in advance, saved the exhaust lifting lug cost of development, shortened its construction cycle; And fix by hanger sleeve one end and flexible member sound rigidity test machine, the other end is parallel bifurcated sheet side otch, passing the hanger perforation by bolt is fixed on the side otch, realize that hanger is static, dynamic rate is tested in advance, this is simple in structure, functional reliability is high, and good endurance is simultaneously with low cost.

Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As shown in Fig. 1 to 6, the stationary installation of testing automobile exhaust lifting lug rigidity, comprise hanger sleeve 2, ear stud 3, described hanger sleeve 2 one ends arrange threaded hole 11 and are used for flexible member sound rigidity test machine 10 fixing, described hanger sleeve 2 other ends are parallel bifurcated sheet, and described parallel bifurcated sheet is provided with side otch 4; Ear stud 3 passes hanger 7 perforation and frame on the side otch 4 of parallel bifurcated sheet; Ear stud 3 two ends arrange convex 9 and screw thread, and ear stud 3 two ends screw chucking nut 5 parallel bifurcated sheet is fixedly clamped on chucking nut 5 and convex 9.Between chucking nut 5 and parallel bifurcated sheet, pad 6 is set, has been used for stepping up buffer action.
During test, the quiet rigidity that this test machine stretches by vertical direction and the mode compressed is tested hanger by the dynamic stiffness of testing hanger perpendicular to the mode of Fig. 1 in-plane up-down vibration, so just can realize the test to auto exhaust hanger rigidity.
