Description

technical field

[0001] The invention belongs to the field of physical performance testing, and in particular relates to a strength and reliability testing device and method for a longitudinal roller guide rail mechanism. Background technique

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The roller guide mechanism is a common mechanical device, which is widely used in industrial equipment, ships, automobiles, logistics and other fields. For large-scale roller guide rail mechanisms, their load and operating speed are relatively high, so the requirements for their strength and reliability are correspondingly increased.

[0004] The inventor found that in order to verify the strength and reliability of the roller guide mechanism, check its bearing capacity and wear during operation to evaluate whether the strength and reliability of the roller guide mechanism after it i...

Examples

Embodiment 1

[0029] In a typical embodiment of the present invention, such as figure 1 As shown, this embodiment discloses a strength and reliability test device for a longitudinal roller guide rail mechanism, including a frame 1 fixed on a plane or a workbench and a simulation platform 4 placed inside the frame 1, and the longitudinal guide rail is fixed on the frame 1 , the roller mechanism is fixed on the simulation platform 4, and the roller mechanism and the longitudinal guide rail are slidingly connected to form a roller guide mechanism, so that the simulation platform 4 can move in the vertical direction through the roller guide mechanism.

[0030] More specifically, in this embodiment, the frame 1 is a rectangular parallelepiped frame 1, and the simulation platform 4 moves in the frame 1, so the shape of the simulation platform 4 is limited by the frame 1, and the projection on the plane is also rectangular.

[0031] In this embodiment, what is to be measured is the roller guide ra...

Embodiment 2

[0049] A strength and reliability test method for a longitudinal roller guide mechanism, using the strength and reliability test device for a longitudinal roller guide mechanism as described in the first aspect, through controlling the expansion and contraction of the hydraulic cylinder 5 multiple times, driving the simulation platform 4 relative to The frame 1 reciprocates to simulate the actual use of the roller guide rail mechanism. The distance sensor used measures the movement height of the simulated platform 4, and the tension and pressure force between the roller and the simulated platform 4 is measured by the pressure sensor.

[0050] Wherein, the concrete operating process of hydraulic cylinder 5 is as follows:

[0051] Free Ascent: If figure 2 As shown, the bottom of the two hydraulic cylinders 5 feeds oil, and the top oil returns to open. Under the action of the bottom oil pressure, the simulation platform 4 rises, the head space of the hydraulic cylinders 5 decrea...
