Device for detecting strength of mechanical parts

Abstract

The invention discloses a lifting device for detecting the strength of mechanical parts. When a workpiece is subjected to impact strength detection, a rotary driving mechanism is lowered to the bottomunder the control of a lifting control mechanism, and a rotary impact mechanism is driven by the rotary driving mechanism to the required test speed; when the rotation speed is reached, the rotary driving mechanism is separated from the rotary impact mechanism, and the lifting control mechanism rapidly drives the rotary impact mechanism to rise to the height of an impact test, so as to use the rotary impact mechanism to perform the impact test on the workpiece; in this way, the impact of a rotary driving motor of the rotary driving mechanism can be well reduced, and at the same time, a heavyload impact effect can be achieved, the detection capability of the strength detection can be improved, and the detection effect can be ensured. According to the lifting device for detecting the strength of the mechanical parts provided by the invention, the impact test of different positions of the workpiece can be realized to facilitate the detection of the impact strength of the workpiece.

Description

technical field [0001] The invention relates to the field of strength detection of mechanical parts, in particular to a detection device for the strength of mechanical parts. Background technique [0002] At present, for some mechanical parts, such as steel columns, axles, steel pipes and other column or shaft and pipe parts, it is necessary to test their strength many times before mass production after design. Determination, in order to ensure the qualified rate of mass production, especially for the impact strength and fatigue resistance of parts, etc., when testing the strength, it is necessary to carry out impact tests to calculate its impact strength and fatigue resistance Wait. The current impact test generally uses the motor and the flywheel for impact. In this impact test, when the motor drives the flywheel to rotate, it will also be subject to great vibration and speed impact, resulting in a low service life of the motor. Generally, only It can be applied to the e...

Problems solved by technology

The current impact test generally uses the motor and the flywheel for impact. In this impact test, when the motor drives the flywheel to rotate, it will also be subjected to great vibration and speed impact, resulting in a low service life of the motor. Generally, only It can be applied to the experimental detection of relatively small samples, but it is difficult to apply to industrially produced parts
