Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments will be exemplified in conjunction with the accompanying drawings. It should be noted that the present embodiment is illustrative, not restrictive, and the scope of the invention should not be limited thereby.
A drop test machine for a frame front fork assembly comprises a base 9, an outer frame 1, an inner frame 2 and a lifting frame 4, wherein an impact table 6 extending upwards is fixedly arranged in the middle of the top surface of the base, a yielding groove 7 which surrounds the periphery of the impact table and extends downwards is manufactured on the top surface of the base, and the outer frame extending upwards is fixedly connected to four corners of the top surface of the base; an inner frame extending upwards is fixedly connected to the plane of the bottom of the abdicating groove, and a buffer spring 8 sleeved outside the inner frame is fixedly connected in the abdicating groove; the inner frame is sleeved with a lifting frame which is connected with the lifting frame in a lifting sliding way, and a plurality of hanging ropes 5 which are matched with and hang the front fork assembly of the frame are fixedly hung on the inner wall of the lifting frame; the top of the outer frame is symmetrically and fixedly connected with a plurality of windlasses 3 for providing ascending power for the lifting frame.
