Abstract

The invention discloses a motor test bench protection device. The device comprises an outer cover and an inner cover, wherein a lower end of the outer cover is connected with a bottom plate through abolt, the inner cover is movably inserted into the inner side of the outer cover, and a sliding rail is welded to the middle of the inner side of the outer cover. The device is advantaged in that thestructure of the test bench protection device is newly designed, the utility model provides a protective cover with an adjustable protective length for a motor output shaft, installation is convenient, an inner cavity formed by the rectangular frame type structure is matched with a motor test board, another layer of slidable protective cover is further arranged in a fixed layer, a protective covermovable layer is of a rectangular frame type structure with an opening in one side, an inner cover of the rectangular frame type structure is smaller than an inner cavity of an outer cover of the rectangular frame type structure, the slidable protective cover in the fixed layer is adjusted according to a model and specification of a tested motor, and a seat and the bottom plate assembly are added, so the height of the protective cover can be properly adjusted to adapt to the protective work of motor spindles of different specifications.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a protective device for a motor test bench. Background technique [0002] With the rise of new energy vehicles, the state has introduced corresponding subsidy policies to promote the rapid development of new energy vehicles. Among the components of the entire electric vehicle, the requirements for the parameters of the motor are very strict. Therefore, the performance of the motor needs to be tested and inspected by the motor test bench before loading. However, the existing motor test bench protection device has a fixed protection length in the direction of the motor output shaft, and can only protect test equipment with one axial connection length. When the motor model specification changes, the size and length of the output shaft will also change, which cannot adapt Different axial lengths lead to excessively large protection ranges or too small short lengths, which pose certa...
