Description

Technical Field

[0001] The present application relates to the technical field of guide rails, and in particular to an anti-creep cross guide rail. Background Art

[0002] A common cross guide pair consists of four guide rails and two sets of roller cages. One pair of guide rails is usually mounted back-to-back on the same moving body, while the other pair of guide rails is mounted on a fixed base with their rolling surfaces facing each other. The roller and cage assembly is placed between the two guide rails that form the relative motion.

[0003] Chinese patent publication number CN110821956A discloses a linear anti-creep cross guide pair, comprising a first guide rail and a second parallel guide rail, a retainer assembly, and a gear assembly. Each guide rail is provided with a V-shaped rolling surface, a roller-displacing U-shaped groove is provided at the bottom of the V-shaped rolling surface, and a gear mounting hole is provided on the A surface of each guide rail. The retainer assembly is composed of a plurality of rollers and a plate-shaped retainer with a setting hole for rotatably constraining the rollers. The roller setting holes of the plate-shaped retainer are equidistantly arranged in the middle, and holes for cooperating with the gears are provided on both sides of the setting hole, in the form of round or square holes. Screws are provided at both ends of the guide rails to prevent the retainer assembly from rolling off. The present invention can achieve meshing of the gear and retainer holes, prevent the retainer from moving out of the two guide rails, and ensure that the misalignment does not interfere with the V-groove processed in the guide rails, thereby reducing the processing scrap rate.

[0004] In the above solution, the gears are mounted on the guide rails. This increases the local load on the guide rails, potentially causing deformation over time. This deformation can affect the accuracy and smoothness of the entire creeping cross-guide system, reducing the equipment's operating accuracy and service life. During operation, the gears exert lateral or radial forces on the guide rails, potentially affecting their straightness and causing deviations in the trajectory of moving parts along the rails.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] See also Figure 1-6 As shown, the anti-creep cross guide rail of the present application includes a static rail 01 and a dynamic rail 02. A regular quadrilateral sliding groove is set between the static rail 01 and the dynamic rail 02. A retainer 03 is set in the sliding groove. The retainer 03 includes a stabilizing rod 04 and a sliding rod 05 that is detachably connected to both ends of the stabilizing rod 04. The end of the stabilizing rod 04 is provided with a T-shaped slot 06, which extends along the radial diagonal of the stabilizing rod 04. The end of the sliding rod 05 is provided with a T-shaped post 07 that adapts to the T-shaped slot 06. The T-shaped slot 06 and the T-shaped post 07 cooperate to achieve the connection between the stabilizing rod 04 and the sliding rod 05. When opposite forces are applied in the radial direction of the stabilizing rod 04 and the sliding rod 05, the T-shaped slot 06 and the T-shaped post 07 can be separated, thereby achieving the effect of separating the stabilizing rod 04 and the sliding rod 05. In the long-term practical process, if a part is damaged, the damaged part can be replaced separately, without having to replace the entire retainer 03, thereby reducing the maintenance cost in the later stage.

[0026] Several mounting holes 08 are staggered on either side of the sliding rod 05. Rollers 09 are rotatably mounted within these holes. Two adjacent rollers 09 are mounted perpendicularly to each other on the retaining frame 03. The outer circumferences of the rollers 09 abut against the sides of the sliding groove, ensuring the horizontal stability of the static rail 01 and the dynamic rail 02, preventing any horizontal displacement.

[0027] Stops are provided on opposite sides of the mounting hole 08. The ends of the stoppers extend toward the center of the mounting hole 08. When the roller 09 is installed in the mounting hole 08, the two stoppers abut against the two ends of the roller 09, preventing the roller 09 from falling out of the mounting hole 08.

[0028] The stabilizing rod 04 is provided with a mounting groove 10 extending in the same direction as the T-shaped groove 06, and a gear 11 is rotatably mounted in the mounting groove 10. The outer diameter of the gear 11 is greater than the length of the radial diagonal of the retaining frame 03.

[0029] The static rail 01 and the dynamic rail 02 are both provided with a V-shaped groove 12, and the two side walls of the V-shaped groove 12 are arranged perpendicular to each other. The V-shaped groove 12 on the static rail 01 and the V-shaped groove 12 on the dynamic groove are combined into a sliding groove.

[0030] Both the static rail 01 and the dynamic rail 02 are provided with a receiving groove 18 that is connected to the V-shaped groove 12. A guide bar 13 is provided in the receiving groove 18. The gear 11 is meshed with the guide bar 13.

[0031] The guide bar 13 is evenly distributed with tooth holes that match the gear 11. An oil reservoir 14, which is connected to the tooth holes, is provided on one side of the guide bar 13. During assembly, lubricating fluid is stored in the oil reservoir 14 to provide lubrication for the gear 11 and roller 09 as they rotate. The cooperation between the gear 11 and the guide bar 13 prevents creep during the movement of the dynamic rail 02. By providing a separate guide bar 13, if it becomes damaged, it can be replaced separately, and the retainer 03 can continue to be used. Furthermore, when the gear 11 is mounted on the retainer 03, the retainer 03 can move or adjust the guide rail to a certain extent. This allows the position of the gear 11 to be more flexibly adapted to different operating conditions and transmission requirements. Furthermore, the retainer 03 can provide a certain degree of shock absorption, reducing the impact of vibration from the guide rail or other components on the gear 11. This is very important for vibration-sensitive applications, such as precision instruments and equipment, and can improve the stability and reliability of the system.

[0032] A disassembly groove 15 is provided on the two side walls of the mounting groove 10, and a rotating hole 16 is provided in the middle of the disassembly groove 15. The diameter of the rotating hole 16 is larger than the width of the disassembly groove 15. Prevent the gear 11 from falling off from the rotating hole 16. Fixed shafts that are adapted to the rotating hole 16 are integrally formed on both sides of the gear 11. When a certain pressure is applied to the gear 11, the gear 11 can be removed from the retaining frame 03. It is convenient to replace the gear 11. The retaining frame 03 can usually be removed from the guide rail relatively easily, which makes the maintenance and replacement of the gear 11 more convenient. If the gear 11 is damaged or worn, it can be replaced by simply removing the retaining frame 03 without large-scale disassembly and repair of the guide rail, which reduces maintenance costs and time.

[0033] Both ends of the static rail 01 and the dynamic rail 02 are mounted with fixing posts 17, which are bolts. The ends of the fixing posts abut against the guide bar 13, preventing the guide bar 13 from falling out of the receiving slot 18 when the static rail 01 and the dynamic rail 02 move relative to each other.

[0034] If the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
