The novel contrastingtesting apparatus comprises a driving device, a crank slide block mechanism, an adjusting bolt group, a dynamic pressing plate, spring loading mechanisms, a static platform and a base, and the drivingdevice is connected to the base; the crank slide block mechanism comprises a crank, a connecting rod, linear guide rail pairs and contrasting linear guide rail pairs; the crank is connected with theoutput end of the driving device; the crank is hinged to the connecting rod, and the connecting rod is hinged to the spring loading mechanisms; the upper ends of the spring loading mechanisms are connected with the contrasting linear guide rail pairs, and the lower ends of the spring loading mechanisms are connected with the linear guide rail pairs. By means of the novel contrasting testing apparatus for simulating the heavy load radar linear guide rail pair life, a disc spring device is utilized to conduct load simulation on the stress state of a heavy load radar in actual work; through the crank slide block mechanism, reciprocating rectilinear movement of the linear guide rail pairs is achieved to simulate the work state of the radar in the actual work, and contrasting tests for simulating the radar linear guide rail pair life under different preprocessing and working environments are completed.
Description
technical field [0001] The invention relates to a comparative test device, in particular to a novel simulated heavy-duty radar linear guide pair life comparative test device. Background technique [0002] The linear guide rail pair is composed of linear guide rails, balls and sliders. As a new type of functional part, its function is to support and guide the moving parts and make reciprocating linear motion in a given direction. The linear guide pair can bear a certain torque and can realize high-precision linear motion under high load conditions. At present, it is widely used in various machine tool equipment industries, automation industries and military industries. [0003] With the continuous improvement of equipment adaptability requirements, higher and higher requirements are put forward for the use of linear guide rail pairs, mainly reflected in the continuous improvement of adaptability and reliability requirements in heavy loads, complex environments, and harsh env...
