Abstract
Claims
1. A test device for the life and durability performance of a slide rail slider bearing, comprising a base (1), a mounting plate (2) fixed on the base (1) and a drive belt (5), a slide rail (3) fixed on the mounting plate (2) and a movable plate (4) slidably disposed on the slide rail (3), wherein the bearing to be tested is disposed between the slide rail (3) and the movable plate (4), and the movable plate (4) is fixed on the drive belt (5), characterized in that: The mounting plate (2) has several rows of threaded holes (6), each threaded hole (6) in each row has the same specifications, and the specifications of the threaded holes (6) in each row are different.
2. The slide rail slider bearing life endurance performance test device according to claim 1, wherein: The drive belt (5) includes a drive motor (51), a connecting belt (52) and a driven pulley (53). The drive motor (51) and the driven pulley (53) are respectively fixed on the two ends of the horizontal direction of the mounting plate (2). The drive motor (51) has a drive pulley coaxially sleeved on its shaft. The connecting belt (52) is sleeved on the drive pulley and the driven pulley (53) and fixed in the middle to the movable plate (4). The horizontal direction is the length direction of the slide rail (3) and the vertical direction is the direction perpendicular to it.
3. The slide rail slider bearing life endurance performance test device according to claim 2, characterized in that: The mounting plate (2) has vertically extending mounting rails (21) on both sides in the horizontal direction. The drive motor (51) and the driven wheel (53) are respectively mounted on the two mounting rails (21) to adjust the installation position along the vertical direction of the mounting plate (2).
4. The slide rail slider bearing life endurance performance test device according to claim 3, characterized in that: The mounting plate (2) is provided with a feedback device (7) near the slide rail (3), and the lower side of the movable plate (4) is provided with a trigger plate (8). When the movable plate (4) carries the trigger plate (8) past the feedback device (7), the feedback device (7) provides feedback on the position of the movable plate (4) and drives the drive motor (51) to reverse, so that the movable plate (4) moves back and forth.
5. The test device for testing the life and durability of slide rail and slider bearings according to claim 4, characterized in that: The feedback device (7) includes a sensor (71) and a swing rod (72). The sensor (71) is fixedly mounted on the mounting plate (2). A transmission rod (73) is rotatably mounted on the sensor (71). One end of the swing rod (72) is mounted on the transmission rod (73) and connected to the transmission rod (73) by a key. The other end is a free end. The trigger plate (8) is an L-shaped plate made by bending the end of a long plate downward. One surface of the L-shaped plate is fixed on the lower side of the movable plate (4), and the other surface serves as the trigger surface. When the movable plate (4) carries the trigger plate (8) through the feedback device (7), the trigger surface collides with the end of the swing rod (72), causing the swing rod (72) to swing, thereby driving the transmission rod (73) to rotate. A displacement sensor (31) is provided near the end of the slide rail (3). The displacement sensor (31) and the sensor (71) are spaced apart, forming a motion space for the movable plate (4) to reciprocate.
6. The slide rail slider bearing life endurance performance test device according to claim 5, characterized in that: The mounting plate (2) is provided with limiting square tubes (22) at both ends of the slide rail (3), and several buffer rubbers (23) are fixed on the side of the two limiting square tubes (22) facing the slide rail (3).
7. The slide rail slider bearing life endurance performance test device according to claim 6, characterized in that: The end of the limiting square tube (22) is fixed to the mounting plate (2) by a triangular angle steel (221).
8. The test apparatus for testing the life and durability performance of slide rail and slider bearings according to any one of claims 1 to 7, characterized in that: The upper side of the movable plate (4) is fixed with a loading box (41).
