[0002] In industrial production, many devices require guide rails to achieve high-precision linear motion, and under certain special operating conditions, these guide rails need to withstand significant lateral loads. For example, in large stamping equipment, heavy machining equipment, and some automated logistics handling systems, existing ordinary V-shaped guide rails are prone to accelerated wear, decreased accuracy, and even structural damage when subjected to lateral loads, seriously affecting the normal operation and service life of the equipment. Currently available guide rail products either fail to meet the requirements of lateral loads or employ complex and expensive structural designs to withstand heavy loads, increasing costs and maintenance difficulties.

[0003] Patent document CN211330994U discloses a V-shaped guide plate structure, including a bump, a concave block, and thin copper sheets. The bump includes a base block with a V-shaped guide convex surface on the top of the base block. The two sides of the V-shaped guide convex surface extend outward from the base block and form a first guide groove with the base block. Two sets of equally spaced threaded holes are symmetrically arranged on the V-shaped guide convex surface. A stop block is provided at the edge of the V-shaped guide convex surface, and the stop block extends along the edge of the V-shaped guide convex surface to both ends of the V-shaped guide convex surface. The concave block includes a base with a V-shaped guide concave surface on the top surface of the base. The two sides of the V-shaped guide concave surface extend outward from the base, and a second guide groove and a connecting hole are opened on the outer end face of the V-shaped guide concave surface. Two thin copper sheets are provided, located between the V-shaped guide convex surface of the bump and the V-shaped guide concave surface of the concave block. The thin copper sheets are symmetrically installed on the V-shaped guide convex surface of the bump through threaded holes.

[0004] In the above solutions, the guide plate structure cannot avoid problems such as accelerated wear, decreased accuracy, or even structural damage when subjected to lateral heavy loads. Therefore, it is necessary to provide a guide rail structure that can withstand lateral heavy loads to overcome the shortcomings of the existing technology. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] Example 1:

[0028] In this embodiment, as Figure 1-5 As shown, the present invention proposes a guide rail structure capable of withstanding lateral heavy loads, including a guide rail body 1 and a slider assembly 2. The guide rail body has a V-groove 11 in the middle, and the bottom of the slider assembly has a V-shaped protrusion that matches the V-groove. The slider assembly works in conjunction with the guide rail body. The bottom of the V-groove has a reinforcing rib 12, and the slope surface of the V-groove is symmetrically provided with a lubrication assembly 3 to reduce the sliding friction coefficient. Lateral support seats 4 are symmetrically provided on both sides of the guide rail to provide buffering force for the slider, further improving the guide rail's ability to withstand lateral heavy loads.

[0029] In this example, the combination of V-grooves and reinforcing ribs enhances the rigidity of the guide rail body and resists deformation. The lateral support directly provides reverse support force to the slider, dispersing lateral loads and preventing stress concentration that could lead to guide rail twisting or breakage, thus enhancing the resistance to lateral heavy loads. The lubrication components achieve solid-state self-lubrication, reducing the friction coefficient of the V-groove ramp surface. Especially under high-pressure lateral loads, it can maintain a low-friction state, significantly extending the life of the guide rail. The triple protection of structural reinforcement, lubrication optimization, and lateral support ensures that the guide rail maintains high motion accuracy under heavy loads, avoiding positioning deviations caused by deformation or wear.

[0030] In this embodiment, the reinforcing rib is further configured to have a trapezoidal cross-sectional shape. The reinforcing rib can enhance the overall strength and deformation resistance of the guide rail body. The trapezoidal surface can also abut against the side of the lubrication component to improve stability. The reinforcing rib can also have a triangular cross-sectional shape.

[0031] In this embodiment, the slider assembly is further configured to include a slider 21 and a buffer block 22. The bottom of the slider abuts against the lubrication assembly. The end face of the slider is provided with a first mounting hole, and the buffer block is provided with a second mounting hole 221. Bolts pass through the second mounting hole and the first mounting hole in sequence to install the buffer block on the slider.

[0032] In this example, mounting hole one is not shown in the figure. Mounting hole one corresponds to mounting hole two. The buffer block is made of high elastic rubber or polyurethane material, which has good buffering and energy absorption performance. When the slider is subjected to limit heavy load, the buffer block can absorb most of the impact force, reduce damage to the guide rail and slider, and reduce vibration and noise caused by rigid collision.

[0033] In this embodiment, the lubrication assembly is further configured to include a brass plate 31 and graphite pillars. The bottom surface of the brass plate abuts against the V-groove slope surface, and the side surface of the brass plate abuts against the side surface of the reinforcing rib. The brass plate has a central array of mounting holes 331 and a V-groove slope surface array of mounting holes 413. Bolts are passed through mounting holes 3 and 4 in sequence to mount the brass plate on the guide rail. The graphite pillar array is embedded in the brass plate.

[0034] In this example, the graphite column is not shown in the figure. The technology of inlaying graphite columns with brass plates is an existing technology and product that can be directly purchased from the market. The lubrication component has the advantages of long-term self-lubrication, high temperature and high pressure resistance, and easy replacement and maintenance. The lubrication component enables the slider component to form a uniform lubricating oil film during the sliding process, reducing the coefficient of friction and improving the motion accuracy and service life of the guide rail.

[0035] In this embodiment, the guide rail body is further provided with mounting holes 14 on both sides.

[0036] In this embodiment, the lateral support array is further configured to have mounting holes 6 and 41, and bolts are passed through mounting holes 6 and 5 in sequence to install the lateral support on the guide rail body.

[0037] In this example, since the lateral support seats are connected by bolts, if a single lateral support seat or both lateral support seats are damaged, they can be replaced without replacing the guide rail body, making maintenance more convenient and cost-effective. At the same time, multiple holes can improve the connection strength.

[0038] In this embodiment, the guide rail body is further configured such that the two ends of the guide rail body are provided with limiting grooves 15 and mounting holes 16, the limiting plate 5 is inserted into the limiting groove, the bottom of the limiting plate is provided with mounting holes 51, and the bolts pass through the mounting holes 51 and 7 in sequence to fix the limiting plate to the guide rail body.

[0039] In this example, the presence of the limiting plate can limit the slider's stroke and prevent it from coming off at extreme positions, which could lead to equipment accidents. The limiting plate reinforces both ends of the guide rail, which can prevent the V-groove opening from deforming and enhance the end rigidity. At the same time, the use of slot + bolt dual fixing method can improve the structural reliability.

[0040] Example 2:

[0041] In this embodiment, as Figure 1-5As shown, based on Embodiment 1, a drive assembly 6 is provided at one end of the guide rail body. The output end of the drive assembly is connected to one end of the shaft 7. One end of the shaft is connected to the output end of the drive assembly. The other end of the shaft extends through the limiting plate to the guide rail body in the set direction. The slider assembly is sleeved on the shaft.

[0042] In this embodiment, the inner side of the limiting plate is provided with an annular groove, a bearing is installed in the annular groove, and the bearing is movably connected to the shaft.
