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

The invention discloses a lifting device for testing the strength of mechanical spare parts. When the invention detects the impact strength of a workpiece, the rotary drive mechanism descends to the bottom under the control of the lifting control mechanism, and the rotary impact mechanism is controlled by the rotary drive mechanism. Drive to the required test speed, when the speed reaches the speed, the rotary drive mechanism is separated from the rotary impact mechanism, and the lifting control mechanism quickly drives the rotary impact mechanism to the height of the impact test, so that the rotary impact mechanism can be used to The workpiece is subjected to an impact test, which can well reduce the impact on the rotary drive motor of the rotary drive mechanism. At the same time, it can realize the heavy-duty impact effect, improve the detection ability of strength detection, and ensure the detection effect. The invention can also realize different positions of the workpiece. impact test, in order to detect 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...
