Description

Technical Field

[0001] The utility model relates to the field of cross guide rails, in particular to an anti-creep cross guide rail pair. Background Art

[0002] Cross roller guides are also called cross roller guides. They use a unique roller retaining mechanism, such as an R-type roller cage that shortens the spacing between rollers, to increase the effective contact length of the rollers. The combination of roller cages and dedicated V-type rails, with high-precision surfaces that undergo special heat treatment, makes this a highly rigid, high-precision, compact limited linear motion system.

[0003] The existing patent CN220452497U discloses an anti-creep cross guide pair. When the fixed part of the second rack and the recessed part of the intermediate block guide are fixed to each other, in addition to being fixedly connected by screws, they can also be connected by other means such as welding and clamping. For example, matching holes and claws are respectively set in the fixed part of the second rack and the recessed part of the intermediate block guide. By inserting the fixed part of the second rack into the recessed part of the intermediate block guide, they are clamped to each other. Block screws are installed at both ends of each cross guide. The anti-creep gear retainer is assembled into one by snapping the skeleton, rollers and gears. The connection is tight, the retainer is not easy to break, the roller is not easy to fall off, the gear is meshed with the rack installed on the guide rail, and the retainer is prevented from accumulating displacement, so that each stroke is reset to zero. The anti-creep cross guide pair has good load-bearing capacity and sliding accuracy, runs smoothly, and there will be no deviation when adjusting the equipment components.

[0004] The existing device is moved by a roller bracket, which causes damage to the outer surface of the roller when the roller bracket is used for a long time. When the roller is damaged, the roller bracket is discarded, resulting in waste of the remaining intact rollers. Utility Model Content
