Abstract
The invention discloses a leaf spring assembly fatigue test bench. The leaf spring assembly fatigue test bench mainly comprises a base, a movable plate, guide columns, a tested leaf spring assembly, guide rails, trolley wheels, trolleys, a mandrel, and an air cylinder or oil cylinder; the air cylinder or oil cylinder is fixed on the base, and the piston rod of the air cylinder or oil cylinder is fixedly connected with the movable plate; the movable plate can slide along the guide columns under the driving the piston rod of thee air cylinder or oil cylinder; the trolleys are with provided with the trolley wheels; and the trolley wheels are arranged in the guide rails and can slide along the guide rails. When a test is carried out, the lifting lugs of the leaf spring assembly are installed on the trolleys, and the middle of the leaf spring assembly is fixedly connected with the movable plate, and then, the air cylinder or oil cylinder is started to work, and the real driving condition of a vehicle can be simulated, and a fatigue resistance impact test can be performed on the leaf spring assembly, and test time and the magnitude of load can be controlled by a computer. The leaf spring assembly fatigue test bench has the advantages of simple structure, accurate and reliable test results, convenient operation, high efficiency, high adaptability and the like. The leaf spring assembly fatigue test bench can be applied to fatigue resistance impact tests of leaf spring assemblies of different specifications.
Description
Technical field
The present invention relates to automobile leaf spring production technical field, particularly relate to a kind of steel plate spring assembly fatigue test board.
Background technology
Automobile leaf spring is the vitals of automobile suspension system, to vehicle complete vehicle technical feature and security performance most important, and the key factor affecting automobile suspension system rigidity is the fatigue resistance of its leaf spring.In the process of moving, leaf spring, as main damping energy absorbing component, bears fatigue load and shock load to automobile always.Therefore, at leaf spring production link, especially in factory inspection link, endurance test need be carried out to leaf spring, make its performance can reach national quality examination criteria.To this, general manufacturer is many endurance life and impact strengths being detected leaf spring by proving ground test now, but this road method for testing needs service testing, experimentation cost is high, expend time in length, and be difficult to obtain test data, be unfavorable for electronic management product information and follow-uply provide test basis for improving spring performance.
Summary of the invention
For the problems referred to above, the present invention proposes a kind of steel plate spring assembly fatigue test board, by impacting inspection to the endurance of steel plate spring assembly, can simulated automotive road conditions, and the product quality of test verification leaf spring, effectively solves the deficiencies in the prior art.
The technical solution used in the present invention is:
A kind of steel plate spring assembly fatigue test board, mainly comprises base, portable plate, guide pillar, tested steel plate spring assembly, guide rail, trundle, dolly, axle, cylinder or oil cylinder.Wherein, cylinder or oil cylinder are fixedly mounted on base, and its piston rod is arranged on portable plate, and are fixedly connected with this portable plate; Described portable plate 2 is arranged on guide pillar, and under cylinder or cylinder piston rod drive, can slide along four guide pillars 3; Described dolly has trundle, and described trundle is arranged in guide rail, and can slide along guide rail, and described guide rail is concavity and convexity rectangle chute, and its two ends teat, higher than trundle bottom outer-edge, can prevent dolly from rolling.
The present invention is by being arranged on dolly by the two ends hanger of steel plate spring assembly, and be connected in the middle part of spring with cylinder or cylinder movement portion, road conditions can be travelled to steel plate spring assembly imposed load by simulated automotive, repeatedly carry out bench test, and test period and magnitude of load all can be controlled by computer programming, real simulation running car situation can carry out bench test to steel plate spring assembly, and rig test result can carry out data processing by computing machine, intuitively can obtain the strained situation of test findings and leaf spring, there is structure simple, test result accurately and reliably, experimentation cost is low, be easy to operation, efficiency is high, the features such as strong adaptability, the steel plate spring assembly batch that can be applicable to different size model carries out torture test.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Fig. 2 is side-looking structural representation of the present invention
Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described further.
A kind of steel plate spring assembly endurance shock table, see accompanying drawing 1-2, mainly comprises base 1, portable plate 2, guide pillar 3, tested steel plate spring assembly 4, guide rail 5, trundle 6, dolly 7, axle 8, cylinder or oil cylinder 9.Wherein, cylinder or oil cylinder 9 are fixedly mounted on base 1, and its piston rod is arranged on portable plate 2, and are fixedly connected with this portable plate; Described portable plate 2 is arranged on guide pillar 3, and under cylinder or cylinder piston rod drive, can slide along four guide pillars 3; Tested steel plate spring assembly 4 is arranged on dolly 7 by axle 8, described dolly 7 has trundle 6, described trundle 6 is arranged in guide rail 5, and can slide along guide rail 5, described guide rail 5 is concavity and convexity rectangle chute, its two ends teat, higher than trundle bottom outer-edge, can prevent dolly from toppling.
When carrying out bench test, be first arranged on two ends dolly 7 by the two ends hanger of steel plate spring assembly by axle 8, the centre of steel plate spring assembly is fixedly connected with portable plate 2.Then startup cylinder or oil cylinder 9 work, and get final product simulated automotive road conditions to steel plate spring assembly imposed load, repeatedly carry out torture test, test period and magnitude of load can be controlled by computer programming.
Preferably, be collect test figure, grasp Test condition, can on portable plate 2 sensor installation, to accept the information such as displacement, speed, motion frequency, load, and be connected with computer system, carry out Data Analysis Services by computing machine.Also on tested steel plate spring assembly, foil gauge can be installed, and connect strainmeter, to export leaf spring strain data in real time and by computer disposal, can obtain the strained situation of test light plate spring, the design for leaf spring is produced and is provided subsequent technology support.
