Two sets of first cylinders 21 can be connected to a switch as needed so that the two sets of first cylinders 21 can operate synchronously and at the same speed. The piston rod of the first cylinder 21 is fixedly installed on the first extrusion plate 22, and the first extrusion plate 22 is in contact with the end of the linear guide rail 50. Several second side plates 23 are fixedly installed on the top front and rear sides of the base plate 10. Several second cylinders 24 can be connected to a switch as needed so that the several second cylinders 24 can operate synchronously and at the same speed.

The piston rod of the second cylinder 24 is fixedly installed on the second extrusion plate 25, and the second extrusion plate 25 is in contact with the side of the linear guide rail 50.

[0053] The test components include: a linear motor 30, a connecting rod 31, a circular plate 32, a pressure sensor 33, and a lower pressure plate 34;

[0054] The linear motor 30 is fixedly installed on the bottom of the top plate 12 and is located directly above the linear guide rail 50. The moving part of the linear motor 30 is detachably connected to the connecting rod 31 through the connecting assembly. The circular plate 32 is fixedly installed on the bottom of the connecting rod 31. The pressure sensor 33 is fixedly installed on the bottom of the circular plate 32. The lower pressure plate 34 is fixedly installed on the bottom of the pressure sensor 33 and can squeeze the slider on the linear guide rail 50.

[0058] Step 1: Place the linear guide rail 50 between two sets of first extrusion plates 22 and several second extrusion plates 25. Then, the first cylinder 21 and the second cylinder 24 will cause the first extrusion plates 22 and the second extrusion plates 25 to extrude the linear guide rail 50, thereby clamping the linear guide rail 50.

[0059] Step 2: The lower pressure plate 34 is lowered by the hydraulic cylinder 11. When the lower pressure plate 34 is lowered, it will squeeze the slider on the linear guide rail 50 until the pressure sensor 33 is at the required value. Then, the slider will be moved back and forth by the linear motor 30. In this way, the life of the linear guide rail 50 can be tested under different load conditions.
