Abstract
Description
Technical Field
[0001] This utility model relates to the field of grooved guide rails, and in particular to a grooved guide rail conveying mechanism with an anti-deviation limiting structure. Background Technology
[0002] In modern industrial production, trough-type guide rail conveyors, as core components of material handling, are widely used in automated production lines in automobile manufacturing, electronic assembly, and machining. Through their trough structure, they guide and support materials, enabling continuous and stable conveying operations and effectively improving production efficiency.
[0003] However, traditional trough-type guide rails mostly use a single trough structure to limit the material, relying solely on the contact between the trough wall and the material to constrain the conveying direction. But in high-speed operation, heavy-load, or long-distance conveying scenarios, the material is prone to lateral deviation, tipping, or even detachment from the guide rail due to inertia, vibration, or guide rail installation errors, resulting in a decrease in transmission accuracy. To address this issue, a trough-type guide rail conveying mechanism with an anti-deviation limiting structure is proposed. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a grooved guide rail conveying mechanism with an anti-deviation limiting structure, which aims to solve the problem in the prior art that "traditional grooved guide rail conveying devices may experience lateral deviation, tilting, or even detachment from the guide rail due to inertia, vibration, or installation errors during high-speed, heavy-load, or long-distance conveying, resulting in a decrease in transmission accuracy".
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a grooved guide rail conveying mechanism with an anti-deviation limiting structure, comprising a grooved guide rail and a sliding member. The sliding member is slidably connected to the inner wall of the grooved guide rail. An mounting platform is fixedly installed on the upper part of the sliding member. Connecting members are fixedly installed on both the left and right sides of the sliding member by bolts. Rolling members are installed on the lower part of the connecting members. Auxiliary rails are fixedly installed on both the left and right sides of the grooved guide rail by fastening bolts. A groove is formed on the side of the auxiliary rail away from the grooved guide rail. The rolling member rolls on the inner wall of the groove. A slide rail is fixedly connected to the upper part of the side of the auxiliary rail away from the grooved guide rail. A sliding groove is formed on the side of the connecting member close to the sliding member. The sliding groove is slidably connected to the outer side of the slide rail.
[0006] As a further description of the above technical solution:
[0007] The two sets of connectors are fixedly connected to the opposite side of the connector with positioning pins, which are inserted into the inner walls of the left and right sides of the sliding member.
[0008] As a further description of the above technical solution:
[0009] Positioning posts are provided on opposite sides of the two sets of auxiliary rails, and the positioning posts on the outer side of the auxiliary rails are inserted into the inner wall of the grooved guide rail.
[0010] As a further description of the above technical solution:
[0011] The connector is U-shaped.
[0012] As a further description of the above technical solution:
[0013] The rolling element consists of a rotating shaft and a roller, with the rotating shaft of the rolling element fixedly connected to the inner wall of the connecting element.
[0014] As a further description of the above technical solution:
[0015] The upper diameter of the connector is larger than the lower diameter, and it is triangular in shape.
[0016] As a further description of the above technical solution:
[0017] The groove is U-shaped.
[0018] This utility model has the following beneficial effects:
[0019] 1. In this utility model, a double-limiting structure in the horizontal direction is formed by the cooperation between the rolling element and the groove of the auxiliary rail, and the sliding constraint of the connecting element on the slide rail. When the sliding element runs in the grooved guide rail, the rolling element rolls along the U-shaped groove of the auxiliary rail, while the sliding groove of the connecting element cooperates with the slide rail, effectively limiting the lateral displacement of the sliding element. Compared with the traditional single groove limiting structure, the conveying accuracy is significantly improved, which can meet the needs of high-precision production scenarios.
[0020] 2. In this utility model, the auxiliary rail is connected to the grooved guide rail via fastening bolts. This modular installation method makes the installation, disassembly, and replacement of the auxiliary rail more convenient. When maintenance or adjustment of the conveying device is required, the auxiliary rail and related components can be quickly disassembled, improving maintenance efficiency. Simultaneously, the standardized design of each component facilitates the replacement and storage of parts, reducing maintenance costs. Furthermore, the placement of positioning posts and pins helps to quickly and accurately position the components during installation, reducing debugging time and improving installation efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figures 1-3 This utility model provides an embodiment of a grooved guide rail conveying mechanism with an anti-deviation limiting structure, comprising a grooved guide rail 1 and a sliding member 2. The sliding member 2 is slidably connected to the inner wall of the grooved guide rail 1. The grooved guide rail 1 serves as the main frame of the conveying device, and its inner wall provides a straight running track for the sliding member 2. Its grooved structure constrains the displacement of the sliding member 2 through the side wall, forming an initial guiding function. An mounting platform 3 is fixedly installed on the upper part of the sliding member 2, serving as a connection medium between the material and the sliding member 2. Connecting members 4 are fixedly installed on both sides of the sliding member 2 by bolts, used to install rolling members 5, which constrain lateral deviation through the rolling of the rollers. The inner sliding groove 9 slides in cooperation with the auxiliary rail 6 and the sliding rail 8 to form a secondary limiting in the "horizontal + vertical" direction, preventing the sliding member 2 from tilting or derailing. The lower part of the connecting member 4 is equipped with a rolling member 5, which consists of a rotating shaft and a roller. The rotating shaft of the rolling member 5 is fixedly connected to the inner wall of the connecting member 4, converting traditional sliding friction into rolling friction, reducing running resistance by about 60%, and is suitable for high-speed conveying scenarios.
[0028] Reference Figures 1-3Auxiliary rails 6 are fixedly installed on both sides of the grooved guide rail 1 by fastening bolts 7. The outer U-shaped groove 11 provides a rolling path for the rolling element 5. The lateral displacement of the sliding element 2 is restricted by geometric constraints. The fastening bolts 7 fix the auxiliary rails 6 to both sides of the grooved guide rail 1 and provide sufficient preload. The side of the auxiliary rail 6 away from the grooved guide rail 1 has a groove 11. The rolling element 5 rolls on the inner wall of the groove 11. The upper part of the side of the auxiliary rail 6 away from the grooved guide rail 1 is fixedly connected to the slide rail 8. The side of the connecting element 4 near the sliding element 2 has a sliding groove 9. The slide rail 8 and the sliding groove 9 of the connecting element 4 cooperate to form a rigid limit in the horizontal direction to prevent the sliding element 2 from shifting due to inertia when starting and stopping. The sliding groove 9 is slidably connected to the outside of the slide rail 8 to constrain the vertical jump and lateral swing of the connecting element 4 and ensure that the sliding element 2 moves accurately along the axis of the guide rail.
[0029] Reference Figures 1-3 Two sets of connecting parts 4 are fixedly connected to opposite sides with positioning pins 10. The positioning pins 10 are inserted into the inner walls of the left and right sides of the sliding parts 2. The positioning pins 10 are inserted into the sliding parts 2 to eliminate the assembly gap between the connecting parts 4 and the sliding parts 2, ensuring the stability of the limiting force transmission. Two sets of auxiliary rails 6 are provided with positioning posts 12 on opposite sides. The positioning posts 12 on the outer side of the auxiliary rails 6 are inserted into the inner wall of the grooved guide rail 1. The positioning posts 12 are inserted into the grooved guide rail 1 and, together with the fastening bolts 7, achieve high-precision installation, ensuring that the straightness deviation between itself and the grooved guide rail 1 is ≤0.05mm / m. The connecting parts 4 are set in a U shape. The upper diameter of the connecting parts 4 is larger than the lower diameter and is triangular. The U-shaped cross section and the upper diameter larger than the lower triangular shape enhance the bending strength and prevent the connecting parts 4 from deforming under heavy load, which would cause the limiting failure. The groove 11 is set in a U shape.
[0030] Working principle: When in use, the sliding power of the sliding member 2 in the grooved guide rail 1 is usually provided by an external drive device such as a motor or belt drive system. The power is transmitted to the sliding member 2 through the mounting platform 3, which drives it to move along the axis of the grooved guide rail 1.
[0031] The auxiliary rail 6 is fixed on both sides of the grooved guide rail 1 and does not directly participate in the power input, but its groove 11 and slide rail 8 provide motion guidance for the rolling element 5 and the connecting element 4, indirectly ensuring the linear motion accuracy of the sliding element 2.
[0032] When the slider 2 moves, the roller of the rolling element 5 at the bottom of the connector 4 rolls in the U-shaped groove 11 of the auxiliary rail 6. The roller contacts the inner wall of the groove 11, and the lateral displacement of the slider 2 is constrained by rolling friction, and the displacement is controlled within ±0.3mm.
[0033] The upper slide rail 8 of the auxiliary rail 6 and the inner slide groove 9 of the connecting piece 4 form a sliding pair. When the sliding piece 2 shifts laterally, the inner wall of the slide groove 9 contacts the side of the slide rail 8, preventing further shifting through rigid geometric constraints and ensuring the continuity of the limit. The auxiliary rail 6 is inserted into the inner wall hole of the slotted guide rail 1 through the positioning pin 12 to achieve initial positioning, ensuring that the parallelism deviation between the axis of the auxiliary rail 6 and the slotted guide rail 1 is ≤0.05mm / m. After the fastening bolt 7 is tightened, the preload of the bolts through the wedge compression principle further eliminates the installation gap between the auxiliary rail 6 and the slotted guide rail 1, ensuring a rigid connection between the two.
[0034] The connector 4 adopts a U-shaped design with an upper diameter larger than the lower triangular shape to enhance its bending strength. When the sliding member 2 carries materials, the connector 4 can withstand the load in the vertical direction, avoiding limit failure caused by deformation under force and maintaining the normal fit between the rolling member 5 and the groove 11, and between the slide rail 8 and the slide groove 9. The connector 4 is fixed to both sides of the sliding member 2 by bolts, and the locating pin 10 is inserted into the pin hole in the inner wall of the sliding member 2 to eliminate the axial clearance of the bolt connection, ensure the coaxiality of the connector 4 and the sliding member 2, and avoid offset errors caused by eccentric limit force.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
