Technical Field

[0001] The invention relates to the technical field of guide rail connection, and in particular to a novel guide rail connector and an installation method. Background Art

[0002] In modern industrial and mechanical applications, the connectors at the ends of the guide rails are key components to ensure the stability and reliability of the system. However, there are some significant problems with the existing connector design, which affects its performance and service life. First, the nuts of traditional connectors often loosen or even fall off during use, which not only increases maintenance costs but also may cause serious safety hazards. Secondly, the rigidity of existing connectors is insufficient and they are prone to deformation when subjected to large loads or external impacts, thus affecting the stability of the entire system. In addition, uneven stress distribution is also a common problem, which leads to premature fatigue damage in local areas and shortens the service life of the connectors. These problems urgently require an improved design solution to improve the stability, rigidity and uniformity of stress distribution of the connectors, thereby improving the reliability and safety of the overall system. Summary of the invention

[0003] The purpose of the present invention is to provide a new type of guide rail connector and installation method. By setting a protrusion in the middle of the guide plate, on the one hand, the rotation of the bolt can be limited, and on the other hand, the connection stiffness can be improved, the stress distribution can be uniform, and its structure can be optimized to enhance its function, thereby solving the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0031] See also Figure 1-4 A novel guide rail connector includes a connecting guide plate 1, which is located at the intersection of two guide rails 2 and connected to the guide rails 2 through bolts 3.

[0032] The guide plate 1 comprises a limiting side plate 5, a fitting panel 6 and a protruding portion 7. The limiting side plate 5, the fitting panel 6 and the protruding portion 7 are integrally formed by sheet metal, and the connection between the limiting side plate 5, the fitting panel 6 and the protruding portion 7 is rounded.

[0033] The limiting side plate 5, the fitting panel 6 and the protruding portion 7 have the same thickness, and the thickness is between 3 mm and 8 mm, which can avoid unnecessary weight increase while ensuring sufficient strength.

[0034] A protrusion 7 is provided in the middle of the bonding panel 6. The protrusion 7 extends along the axis of the bonding panel 6. The side of the protrusion 7 facing the guide rail 2 is a concave surface, and the side of the protrusion 7 away from the guide rail 2 is a convex surface. The two sides of the axis of the protrusion 7 are symmetrical.

[0035] The longitudinal cross section of the protrusion 7 is U-shaped, and the two sides of the convex surface of the protrusion 7 are limit surfaces 71, which are perpendicular to the bottom surface of the fitting panel 6. The vertical distance between the limit surface 71 and the axis of the screw hole 4 is not less than the radius of the inscribed circle of the nut 8 and less than the radius of the circumscribed circle of the nut 8, and the vertical height of the limit surface 71 is not less than the vertical distance between the top surface and the bottom surface of the nut 8. Through the above-mentioned structural setting, the limit surface 71 can effectively block the rotation of the nut 8, prevent the bolt 3 and the nut 8 from loosening, thereby improving the stability of the installation.

[0036] Limiting side plates 5 are arranged on both sides of the fitting panel 6, the spacing between the limiting side plates 5 is not less than the width of the guide rail 2, the limiting side plates 5 and the fitting panel 6 are perpendicular to each other, the two limiting side plates 5 are distributed in a mirror-symmetrical manner along the central axis of the fitting panel 6, the limiting side plates 5 limit the guide rail 2 from both sides to prevent the guide rails 2 from being skewed, and the seams of the guide rails 2 are effectively protected to ensure their close fitting.

[0037] A row of screw holes 4 are respectively provided on both sides of the protruding portion 7 of the fitting panel 6, and the two rows of screw holes 4 are respectively connected to the two sides of the guide rail 2. The number of screw holes 4 in each row is not less than four and the number is an even number, so that the number of bolts 3 connected at the end of each guide rail 2 is the same, ensuring uniform force at the connection.

[0038] A gasket 9 is provided between the nut 8 and the fitting panel 6 to further increase the force bearing area and friction force between the nut 8 and the guide rail 2 to prevent loosening.

[0039] A novel installation method of a guide rail connector is implemented based on a novel guide rail connector and includes the following steps:

[0040] Step 1: Align the connecting guide plate 1 with the shallow groove at the bottom connecting end of the guide rail 2, so that the fitting panel 6 contacts the guide rail 2, and align the screw hole 4 with the preset through hole of the guide rail 2;

[0041] Step 2: First tighten the bolts 3 and nuts 8 at both ends of the diagonal line, place the gasket 9 on the nut 8, and then align it with the bottom of the screw hole 4. Screw the bolt 3 into the through hole and pass through the screw hole 4, gasket 9 and nut 8 in sequence. Use a wrench to clamp the nut 8 to prevent it from rotating until the bolt head of the bolt 3 and the nut 8 press against the guide rail 2;

[0042] Step 3: Finally, screw in the remaining bolts 3 and nuts 8 in sequence.

[0043] Embodiment 2

[0044] In order to solve the problem of poor connection stiffness of the existing guide plate, the following technical solutions are provided:

[0045] See also Figure 5-6 The difference between this embodiment and the first embodiment lies in the protrusion 7, and the rest of the parts are the same as the first embodiment. The longitudinal section of the protrusion 7 is V-shaped, and the protrusion 7 is composed of two symmetrical reinforcing plates 72. The bottom angle range of the two reinforcing plates 72 is 30°-90°. By setting the reinforcing plates 72, the overall stiffness of the connecting plate 1 can be enhanced, and the stability, bearing capacity and stress distribution of the overall structure can be improved.

[0046] Working principle: The connecting guide plate 1 uses bolts 3, nuts 8 and washers 9 to connect the ends of the two guide rails 2, and a sheet metal protrusion 7 is provided. When the longitudinal section of the protrusion 7 is U-shaped, the limiting surface 71 can effectively block the rotation of the nut 8 and prevent the bolts 3 and the nut 8 from loosening, thereby improving the installation stability. When the longitudinal section of the protrusion 7 is V-shaped, the reinforcing plate 72 can enhance the overall stiffness of the connecting guide plate 1, and improve the stability, bearing capacity and stress distribution of the overall structure.
