The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of embodiments of the disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.

The present exemplary embodiment provides a linear guide pair. Referring to fig. 1 to 6, the linear guide pair includes a guide rail 100, a slider 200, and a connection plate 300. The guide rail 100 includes a first sliding surface on which a first sliding groove 101 is provided; the sliding part comprises a second sliding surface, a second sliding groove 2011 matched with the first sliding groove 101 is formed in the second sliding surface, and the first sliding groove 101 is connected with the second sliding groove 2011 in a sliding mode, so that the basic sliding function of the linear guide rail pair is achieved; the connecting plate 300 is detachably connected to the sliding part 200, so that the specific requirements of customers on different processing strokes can be met by changing the length of the connecting plate 300, and meanwhile, as the connecting plate 300 is detachably connected with the sliding part 200, the connecting plate 300 can be detachably connected with a plurality of sliding parts 200, so that the technical effects are realized. It should be noted that the first slide groove 101 may be disposed on a surface or a side surface of the guide rail 100, and the second slide groove 2011 may be disposed on a surface or a side surface of the slider.

Further, in the linear guide rail pair, the first sliding surface and the second sliding surface may be slidably coupled to each other by a magnetic levitation method, in addition to the first sliding groove 101 and the second sliding groove 2011, so that the sliding coupling between the slider 200 and the guide rail 100 can be also achieved.

In one embodiment, this embodiment provides a connection manner and a relative movement manner between the guide rail 100 and the sliding member 200, that is, rolling members are disposed in a raceway formed by the first sliding groove 101 and the second sliding groove 2011, and the relative movement between the guide rail 100 and the sliding member 200 is realized by the rolling of the rolling members in the raceway.

Specifically, the rolling elements can be balls or rollers, steel balls are used in the ball linear guide rail, and steel columns are used in the ball linear guide rail. The roller linear guide rail is applied to the sliding part, and the cylindrical roller bearing has large total contact area and can bear large load; the ball linear guide rail is applied to the sliding part and is a spherical roller bearing, so that the load born by the ball linear guide rail is relatively small, the contact area is relatively small, and the corresponding friction resistance is also small. In general, the linear roller guide rail has lower speed but better rigidity; and the linear ball guide rail has higher speed and poorer rigidity.

In one embodiment, the raceway formed by the first slide groove 101 and the second slide groove 2011 is a gothic groove, and the gothic groove has a very small adjustable axial clearance, so that the transmission function can be performed easily. If proper pre-tightening load is added, the axial clearance is eliminated, the lead screw has better rigidity, the elastic deformation among the ball, the nut and the lead screw is reduced during bearing, and higher precision is achieved.

In one embodiment, if the slide member 200 is a single slide member, the length of the connecting plate 300 can be increased to meet the requirement of customers for different machining strokes, and the slide member 200 is not enlarged or lengthened, so that the machining difficulty and the machining cost are not increased; the number of the sliders 200 may be 2 or more, and the connecting plate 300 may be detachably linked with at least 2 sliders 200, thereby achieving the above technical effects.

In one embodiment, the components of the slider 200 are specifically illustrated, including a slider 201, and return means 202 connected to opposite ends of the slider 201, i.e., one slider 200 includes 1 slider 201 and 2 return means 202. Each return device 202 is provided with a third chute 2021 which is matched with a raceway formed by the first chute 101 and the second chute 2011. The return device 202 effects a reciprocating movement of the slider 201 along the guide rail 100. The return device 202 may be a gyrator or a return device.

Further, in one embodiment, a dust-proof member 203 is connected to a free end of each return device 202, and here, it should be noted that an opposite side to the connection end of the slider 201 is a free end. Each dust-proof member 203 is provided with a fourth sliding groove 2031 adapted to a raceway formed by the first sliding groove 101 and the second sliding groove 2011, and the fourth sliding groove 2031 is adapted to the third sliding groove 2021. The dust-proof member 203 improves the dust-proof performance of the guide rail 100. The dust-proof member 203 may be a dust-proof plate.

In this way, the first slide groove 101, the second slide groove 2011, the third slide groove 2021 and the fourth slide groove 2031 jointly form a raceway, so that the relative movement between the slider 201 and the guide rail 100 is realized. It should be noted that, the two opposite ends of the slider 201, the two ends of the returning device 202, and the dust-proof piece 203 may be respectively provided with screw holes, and these three components may be detachably connected by screws, or may be fixed or detachably connected by other methods, such as adhesion.

In one embodiment, first mounting holes 301 are respectively provided at both end surfaces of the connection plate 300, and the first mounting holes 301 are used to connect the connection plate 300 with other accessories. A plurality of first connection holes 302 are provided on the connection plate 300, and a plurality of second connection holes 204 matching the plurality of first connection holes 302 are provided on each slider 200.

In one embodiment, a second mounting hole 102 is respectively disposed on both end surfaces of the rail 100, and the second mounting hole 102 is used to connect the rail 100 with other accessories. A plurality of adjustment holes 103 are provided in the guide rail 100, and the adjustment holes 103 are used to finely adjust the parallelism of the guide rail 100.
