Description

Technical Field

[0001] This utility model relates to the field of guide rail retainer technology, and in particular to a guide rail retainer structure that prevents misalignment. Background Technology

[0002] During the operation of cross rails, cages are typically used to prevent contact between rolling elements, thereby reducing noise and friction. In telescopic sliders, the cage not only contains the rolling elements and ensures even load distribution, but it also determines the load capacity of the slider in short-stroke applications.

[0003] Existing cages tend to deviate from their center position after the stroke, which shortens the travel of the guide rail. If a stop is installed at the end of the rail, the cage can hit the stop during the full stroke. Although this forces the cage back to the center position, it causes the rolling motion between the cage and the rollers to change to sliding, increasing friction and heat. The force of the cage hitting the end stop can damage the cage or the guide elements within it.

[0004] Therefore, it is necessary to design a guide rail retainer structure to prevent misalignment. Utility Model Content

[0005] To overcome the drawback of the cage shifting off-center after travel, causing damage to the guide elements, the technical problem is to provide a cage structure that prevents misalignment of the guide rail.

[0006] The technical solution is as follows: A misalignment prevention guide rail retainer structure includes a mounting block 1, a mounting block 2, a cross guide rail 1, a cross guide rail 2, a rack, a retainer, rollers, and gears. The mounting block 1 is convex in shape. Two cross guide rails 1 are fixedly mounted on the mounting block 1. Two cross guide rails 2 are slidably mounted on the mounting block 1. The two cross guide rails 1 are located between the two cross guide rails 2. The mounting block 2 is fixedly mounted between the upper ends of the cross guide rails 2. A rack is fixedly connected to the grooves on the sides of the cross guide rails 1 and 2 that are close to each other. A retainer is slidably mounted at the center of the gap between the cross guide rails 1 and 2. The cross guide rails 1 and 2 are slidably engaged with each other through the retainer. A gear is rotatably mounted in the middle of the retainer. The gears mesh with the racks in the grooves of the cross guide rails 1 and 2. Rollers are slidably mounted on both sides of the retainer.

[0007] Optionally, it also includes rubber blocks, with rubber blocks fixed to both the front and rear ends of the cage.

[0008] Optionally, it also includes guide rods, springs, nuts, mounting brackets, limit blocks, and dampers. Both ends of the cross guide rail one and cross guide rail two have notches, and guide rods are slidably installed in the notches. Nuts are fixed to the ends of the guide rods that are far apart from each other. Springs are fixed between the notches and the nuts, and the springs are located around the guide rods. Mounting brackets are fixedly installed at both ends of the cross guide rail one and cross guide rail two. The fixed end of the damper is fixedly installed on the mounting bracket. Limit blocks are fixed to the telescopic ends of the dampers, and the limit blocks are snapped into the nuts.

[0009] Optionally, it also includes an oil tank, a water pump, and an oil pipe. An oil tank is fixedly installed in the middle of both ends of the mounting block one. An oil pipe is connected to the oil tank through the water pump. Both ends of the oil pipe are fixedly inserted into the mounting block one, and the oil outlet is located above the gap between the cross guide rail one and the cross guide rail two.

[0010] Optionally, the nuts are provided with protrusions on the sides that are close to each other to block the retainer.

[0011] Optionally, the cage and both cross rail one and cross rail two are lubricated and rust-proofed.

[0012] The beneficial effects of this utility model are: by using a forced synchronization mechanism in which gears simultaneously mesh with the racks of cross guide rail one and cross guide rail two, the cage is automatically kept in the center position of the gap between cross guide rail one and cross guide rail two throughout the entire stroke, thus achieving the effect of keeping the cage in the center position after the stroke.

Detailed Implementation

[0020] Example: A misalignment prevention guide rail cage structure, such as Figures 1-6 As shown, it includes mounting block 1, mounting block 2, cross guide rail 1 3, cross guide rail 2 4, rack 5, cage 6, roller 7, and gear 8. Mounting block 1 is U-shaped. Two cross guide rails 1 3 are mounted on mounting block 1 by screws. Two cross guide rails 2 4 are slidably mounted on mounting block 1. The two cross guide rails 1 3 are located between the two cross guide rails 2 4. Mounting block 2 2 is mounted on the upper end of the cross guide rails 2 4 by screws. The cross guide rails 1 3 and cross guide rails 2 4 are close to each other. A rack 5 is fixedly connected to one side of the groove. A retainer 6 is slidably provided at the center of the gap between the cross guide rail 1 3 and the cross guide rail 2 4. The cross guide rail 1 3 and the cross guide rail 2 4 are slidably engaged by the retainer 6. A gear 8 is rotatably provided in the middle of the retainer 6. The gear 8 meshes with the rack 5 in the groove of the cross guide rail 1 3 and the cross guide rail 2 4. Rollers 7 are rolled on both sides of the retainer 6. The retainer 6 and the cross guide rail 1 3 and the cross guide rail 2 4 are all lubricated and rust-proofed.

[0021] like Figure 3 As shown, it also includes rubber blocks 9, and rubber blocks 9 are fixed to both the front and rear ends of the retainer 6.

[0022] like Figure 4 and Figure 5 As shown, it also includes a guide rod 10, a spring 11, a nut 12, a mounting bracket 13, a limiting block 14, and a damper 15. Both ends of the cross guide rail 1 3 and the cross guide rail 2 4 have notches, and the guide rod 10 is slidably installed in each notch. The ends of the guide rods 10 that are far apart from each other are fixedly connected to the nuts 12. The springs 11 are fixedly connected between the notches and the nuts 12. The springs 11 are located around the guide rods 10. Both ends of the cross guide rail 1 3 and the cross guide rail 2 4 are fixedly installed with mounting brackets 13 by screws. The fixed end of the damper 15 is fixedly installed on the mounting bracket 13. The telescopic end of the damper 15 is fixedly connected to the limiting block 14. The limiting block 14 is snapped into the nut 12. The sides of the nuts 12 that are close to each other are provided with protrusions for blocking the retainer 6.

[0023] like Figure 1 and Figure 6As shown, it also includes an oil tank 16, a water pump 17 and an oil pipe 18. The oil tank 16 is installed in the middle of the left and right end faces of the mounting block 1 by screws. The oil tank 16 is connected to the oil pipe 18 through the water pump 17. Both ends of the oil pipe 18 are fixedly inserted into the mounting block 1, and the oil outlet is located above the gap between the cross guide rail 1 3 and the cross guide rail 2 4.

[0024] When mounting block 2 on cross guide rail 2 4 needs to move in a straight line, mounting block 2 2 drives cross guide rail 2 4, which is fixed below it, to move relative to cross guide rail 3. When cross guide rail 2 4 moves, it drives rack 5 in the groove to move synchronously. Since gear 8 in the middle of cage 6 meshes with rack 5 of cross guide rail 3 and cross guide rail 2 4 at the same time, gear 8 will rotate synchronously under the relative movement of the two racks 5. This makes the center of cage 6 move only along the central symmetry plane of the relative movement of cross guide rail 3 and cross guide rail 2 4. No matter where cross guide rail 2 4 moves to, cage 6 will always be in the center position after the stroke ends. During the movement of cage 6, roller 7 rolls under the guidance of cage 6, and at the same time bears and transmits the load. When mounting block 2 2 drives cross guide rail 2 4 to move, a connection is formed. Near the end point, the rubber block 9 at the end of the retainer 6 contacts and pushes the stop block protruding from the nut 12. At this time, the nut 12 drives the guide rod 10 to slide in the notch. The spring 11 located between the nut 12 and the notch is stretched. The limiting block 14 fixed on the nut 12 pushes the telescopic end of the damper 5 to move towards the fixed end and absorbs the thrust. When the mounting block drives the cross guide rail 2 4 to stop moving or move in the opposite direction, the stretched spring 11 drives the nut 12 and the limiting block 14 to reset to the initial position. At the same time, the telescopic end of the damper 15 can slow down the reset speed to avoid the impact caused by too fast reset. When the device needs maintenance, the water pump 17 is started. The water pump 17 pumps the lubricating oil from the oil tank 16 and delivers it to the cross guide rail 1 3 and cross guide rail 2 4 through the oil pipe 18 to keep the movement of cross guide rail 1 3 and cross guide rail 2 4 smooth.
