The invention relates to a multi-condition linear guide rail pair friction wear testing machine comprising a pedestal and a linear guide rail pair detachably connected on the pedestal; the linear guide rail pair comprises linear guide rails and a slide block; the linear guide rails are bolted on the pedestal; the slide block is connected on the linear guide rails in a rolling mode; the structure also comprises a drive unit, a loading unit and a clamping unit used for clamping the slide block; the drive unit is fixed on the pedestal; the clamping unit is matched with the drive unit via a connecting rack; the loading unit is arranged above the slide block; the drive unit is used for adjusting different running-in speeds and running-in distances; the loading unit is used for applying different loads on the slide block; the clamping unit adjusts the slide block tightness so as to realize testing machine friction wear tests of different models and sizes; the testing machine can carry out variable load, variable running-in speed and variable running-in distance friction wear tests of linear guide rail pairs of different models, is compact in structure, and low in cost.

Description

technical field [0001] The invention relates to a multi-working-condition linear guide rail pair friction and wear tester, belonging to mechanical linear guide rail pair friction and wear test devices. Background technique [0002] As a precision linear guide part, the linear guide rail pair realizes rolling friction by means of the rolling elements between the slider and the guide rail. Due to the small friction resistance of the guide rail pair, the difference between dynamic and static friction resistance is small, and it is not easy to crawl at low speeds and has a large load. , high precision, reliability and standardization and other excellent characteristics have been more and more applied and paid attention to by CNC machinery, automated production lines and other fields. The wear and service life of guide rails have a direct impact on the reliability and life of machined parts. At present, there are few types of friction and wear testing machines for linear guide r...

AI Technical Summary

Problems solved by technology

At present, there are few types of friction and wear testing machines for linear guide rail pairs, and basically only suitable for one type of linear guide rail pair. The universality of the testing machine is poor. For different sliders, different friction and wear tests are required. machine, the test efficiency is low, which will bring higher test cost

Existing friction and wear testing machines mainly use the servo system and weight loading method. The cost of the testing machine of the servo system is high, and the testing machine using the weight loading needs to be manually guarded, and the test efficiency is low and the cost is high.
