Problems solved by technology
[0007] In order to solve the problem of inconvenient reading of the circular trajectory, the present invention proposes a feedback method that uses a beam to receive light and convert the light into light spots. However, in this method, the scale beam cannot be too wide (the accuracy cannot be guaranteed) Narrow (insufficient strength, easy to shake) technical contradiction, in order to overcome this technical contradiction, the present invention creatively proposes a trimmable scale assembly, which divides the wide beam with sufficient strength into two areas: specular reflection part and diffuse reflection boss part , overcoming the technical difficulty of balancing strength and precision

The invention discloses a material characteristic testing device based on a centrifugal motion motor main shaft. The material characteristic testing device comprises a centrifugal self-adaptive parallel steering mechanism, a trimmable scale assembly, a main body rack assembly, a rotary clamping assembly and a rotary driving assembly. The invention belongs to the technical field of motor main shaft testing, and particularly relates to a material characteristic testing device based on a centrifugal motion motor main shaft. According to the invention, rotation centrifugal force is taken as driving force, the eccentric centrifugal turntable with uneven weight distribution adjusts the angle in a self-adaptive manner during high-speed rotation, and even if the angle of the cantilever type balancing weight is changed, the laser spotlight is still parallel to the rotation axis under the action of the eccentric centrifugal turntable, so that the accuracy of a measurement result is ensured; the invention also creatively provides a trimmable scale assembly, and the wide cross beam with enough strength is divided into two areas, namely a mirror reflection part and a diffuse reflection boss part, so that the technical problem that the strength and the precision are difficult to consider at the same time is solved.
Description
technical field [0001] The invention belongs to the technical field of motor spindle testing, in particular to a device for testing material properties of a motor spindle based on centrifugal motion. Background technique [0002] The motor spindle is a part with the highest strength requirements in the motor. The material strength of the spindle mainly includes rigidity (the ability to resist deformation) and elasticity (the ability to recover after deformation). In order to simplify the measurement steps and reduce the structural complexity and cost, In addition, the measurement results are fed back more intuitively and accurately. The present invention mainly proposes a measuring device that fixes the laser spotlight on the eccentric counterweight, and feeds back the current bending degree of the main shaft through the size of the drawn aperture. [0003] Although the structure and principle of the above device are simple and easy to implement, the following problems still...
