Automobile clutch damping spring durability test bed

Abstract

The invention relates to the technical field of fatigue testing machines, in particular to an automobile clutch damping spring durability test bed which comprises a testing machine body, a transparentshell, a self-propelled cleaning mechanism and a stepless adjusting spring fixing mechanism, wherein the transparent shell is arranged at the upper end of the testing machine body, the self-propelledcleaning mechanism is fixed on the testing machine body and is in sliding connection with the self-propelled cleaning mechanism, the stepless adjusting spring fixing mechanism is arranged on the peripheral wall of the stepless adjusting spring fixing mechanism around the axis of the testing machine body, and the self-propelled cleaning mechanism is electrically connected with a controller; the automobile clutch damping spring durability test bed solves the problems, can adapt to springs of various sizes through stepless adjustment, is wide in application range, can efficiently and automatically complete oil stain cleaning of the transparent shell of the testing machine, saves manpower, and is simple in structure and cost-saving.

Description

technical field [0001] The invention relates to the technical field of fatigue testing machines, in particular to an automobile clutch damping spring durability test bench. Background technique [0002] Main application: The spring fatigue testing machine is mainly used for the fatigue life test of various coil springs, disc springs, shock absorbers, seal springs, etc. [0003] In the existing spring fatigue testing machine, since there is no device such as a limit block, if a larger-sized spring needs to be tested, you can only find and replace a larger-sized limit plate, resulting in a problem of reduced work efficiency , and the existing spring fatigue testing machine, because there is no fixed block and other devices, there will be grease splashed on the surface of the transparent shell when the device is in operation, and then the dust is easy to bond with the grease, resulting in the inability to clearly observe through the transparent shell To solve the problem of th...

Problems solved by technology

[0003] In the existing spring fatigue testing machine, since there is no device such as a limit block, if a larger-sized spring needs to be tested, you can only find and replace a larger-sized limit plate, resulting in a problem of reduced work efficiency , and the existing spring fatigue testing machine, because there is no fixed block and other devices, there will be grease splashed on the surface of the transparent shell when the device is in operation, and then the dust is easy to bond with the grease, resulting in the inability to clearly observe through the transparent shell The problem of the internal operation of the device, so we propose a fatigue testing machine for the damping spring of the driven plate of the automobile clutch

[0004] Chinese patent CN201821277953.2 discloses a fatigue testing machine for the damping spring of an automobile clutch driven disc, which includes a main body, an adjustment device and a cleaning device, the main body includes a transparent shell and a protective shell, and the adjustment device includes a base, The base is located on the outer surface of the protective shell, and the upper part of the base is fixedly connected with a limiting plate, and the inner side of the limiting plate is fixedly connected with four limiting blocks, and the four outer surfaces are connected with four limiting blocks. hole, a connecting ring is arranged above the limiting disk, four limiting columns are fixedly connected to the bottom surface of the connecting ring, and a fixed spring is arranged between the connecting ring and the limiting disk; Blocks, etc., are convenient for fixing larger-sized springs, which solves the problem of existing spring fatigue testing machines. Since there are no devices such as limit blocks, if you need to test larger-sized springs, you can only find and replace larger-sized springs. The limit plate, resulting in the problem of reduced work efficiency

[0005] However, the scope of application of the above scheme is limited, and the size it provides is only divided into four levels, and its scrubbing mechanism needs to be manually scrubbed around the transparent shell, which is time-consuming and laborious
