[0002] The rolling linear guide pair is a rolling support mechanism with unique mechanical properties that was developed in the late 1970s and gradually improved based on the basic principle of rolling bearings. It is composed of mechanical components such as linear guides, rolling elements (balls or balls), sliders, etc. It plays the role of bearing and guiding the movement of moving parts in mechanical transmission. It has the characteristics of simple structure, small dynamic and static friction coefficient, high positioning accuracy, good precision retention, etc. It has become one of the key basic components of precision CNC equipment. Since the commercialization of linear guide pairs in 1973, they have been widely used in industries such as precision machinery, automation, various power transmissions, semiconductors, medical and aerospace.

[0003] As an important supporting and guiding mechanism in the machinery industry, its performance indicators have also attracted much attention, including comprehensive performance parameters, including operating accuracy, preload drag, vibration, noise, acceleration, temperature rise, etc., functional reliability, accuracy retention, fatigue life and rated dynamic load, as well as static stiffness and rated static load, etc. The detection and testing of these parameters are crucial for product selection, verification and upgrading.

[0031] This test bench can detect and test multiple performances of rolling linear guide pairs on the same test bench. The tests that can be performed include four categories: comprehensive performance test, reliability test, life test and static stiffness test. The comprehensive performance test indicators include: motion accuracy, preload drag, vibration, acceleration, temperature rise, reliability test includes accuracy reliability test and functional reliability test, life test refers to the measurement of fatigue life and rated dynamic load, and static stiffness test refers to the measurement of vertical static stiffness and rated static load.

[0032] The test bench test device measures the comprehensive performance index of the rolling linear guide pair in the following way: the drag component 2 drags the loading component 3 to drive the guide of the tested guide pair 43 to reciprocate at a given speed and acceleration, and adjusts the positions of the photoelectric switch block 110 and the contact switch block 19 to adjust the expected stroke; the S-type tension and pressure sensor 44 outputs the friction force of the guide pair 43 under uniform speed conditions, that is, the pre-tightening drag force; the temperature sensor 47 outputs the temperature rise of the tested guide pair 43 with continuous reciprocating motion; the three-axis vibration sensor 49 outputs the vibration signals of the tested guide pair 43 in two directions and the acceleration signals in the direction of motion; the data measured by the three contact displacement sensors 48 can be used to calculate the distortion of the tested guide pair 43 during the motion process and the parallelism in two directions.

[0033] The test bench uses the following method to test the reliability of rolling linear guide rails: the loading component 3 applies corresponding pressure to the six sets of guide rails 43 under test; the dragging component 2 drags the loading component 3 to drive the guide rails of the guide rails 43 under test to reciprocate at a given speed and acceleration; the positions of the travel switch baffle 110 and the limit switch block 19 are adjusted to adjust the expected travel; the contact displacement sensor 48 and the S-type tension and pressure sensor 44 are used to measure the operating accuracy and preload drag force according to the specified test cycle, and the data is recorded until the accuracy does not meet the requirements and the test ends.

[0034] The test method of this test bench for the functional reliability of rolling linear guide pairs is as follows: the loading component 3 applies corresponding pressure to the six sets of tested guide pairs 43, the dragging component 2 drags the loading component 3 to drive the guide rails of the tested guide pairs 43 to reciprocate at a given speed and acceleration, and adjusts the positions of the travel switch baffle 110 and the limit switch block 19 to adjust the expected travel; during the experiment, the type and time of each failure are recorded until an irreparable failure occurs, the test is terminated, and the average failure interval time is calculated.

[0035] The test method for the fatigue life of rolling linear guide pairs of this test bench is as follows: the loading component 3 applies a specified pressure to the six sets of guide pairs 43 under test, the dragging component 2 drags the loading component 3 to drive the guide rails of the guide pairs 43 under test to reciprocate at a given speed and acceleration, and adjusts the positions of the travel switch baffle 110 and the limit switch block 19 to adjust the expected travel; if abnormal vibration is found during the experiment, stop immediately, and detect the peeling and pitting of the guide rails, sliders and rolling elements of the guide pairs 43 under test offline. If the peeling and pitting meet the termination conditions specified in the standard, the test is terminated, and the resulting running time or mileage is the fatigue life of the guide pairs 43 under the specified pressure.

[0036] The test method of the test bench for the rated dynamic load of the rolling linear guide pair is as follows: the loading component 3 applies a pressure equivalent to the rated dynamic load to the six tested guide pairs 43, the dragging component 2 drags the loading component 3 to drive the guide rails of the tested guide pair 43 to reciprocate at a given speed and acceleration, and the positions of the travel switch baffle 110 and the limit switch block 19 are adjusted to adjust the expected stroke; so that the tested guide pair 43 can move continuously for 50km under the rated dynamic load loading condition, and the characteristic data of fatigue pitting corrosion are reflected by various sensors. If only less than 10% of the products suffer from fatigue pitting corrosion, the calibrated rated dynamic load of the product is reasonable and reliable.

[0037] The test method of this test bench for the vertical static stiffness of the rolling linear guide pair is: the loading component 3 continuously applies a prescribed pressure to the six sets of the guide pairs 43 under test until the prescribed pressure is reached to ensure that the preload force of the guide pairs 43 under test does not fail, and then records the data of the displacement sensor 48 when the two vertical adapter plates are in contact, calculates the displacement change with the pressure change, and draws a pressure-displacement curve, the slope of the curve is the vertical static stiffness of the guide pair 43 under test.

[0038] The test method of this test bench for the rated static load of the rolling linear guide pair is: the loading component 3 continuously applies increasing pressure to the six sets of the guide pairs 43 under test according to the program, and then records the data of the displacement sensor 48 when the two vertical adapter plates are in contact, calculates the displacement change with the pressure change, and draws the pressure-displacement curve until the stiffness suddenly changes. At this time, the applied pressure is the rated static load of the guide pair 43 under test.

[0039] This test bench can carry out comprehensive performance tests, reliability tests, fatigue life tests and static stiffness tests on the same equipment, and can meet the comprehensive measurement of all parameters of rolling linear guide pairs; this test bench can load 6 guides at a time, and the loads of the upper two tested guides and the lower two tested guides can be different, which improves the experimental efficiency; this test bench uses a hydraulic system for loading, and the loading force is accurate and controllable, with a simple structure and a high power-to-weight ratio; this test bench uses three contact displacement sensors in the measurement of running accuracy, taking into account the distortion measurement of the tested guides, and the calculation of running accuracy is accurate and reliable; this test bench can realize the test and measurement of rolling linear guide pairs of different models by replacing the measurement and adapter plates, achieving full coverage of rolling linear guide pairs on the market.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
