Description

Technical Field

[0001] This utility model belongs to the field of linear guide technology, specifically relating to a rolling linear guide. Background Technology

[0002] Rolling linear guides, as core components for achieving precise linear motion, are widely used in automated production lines, CNC machine tools, precision testing instruments, and electronic equipment assembly platforms. Traditional rolling linear guides achieve motion by rolling balls or rollers between the guide rail and the sliding block's raceway. However, in practical applications, the width of the sliding block in traditional rolling guides is usually close to the width of the guide rail itself, resulting in insufficient lateral support. This causes the sliding block to tilt, leading to deviations from the preset straight line and a decrease in guide rail accuracy. Utility Model Content

[0003] The main objective of this invention is to provide a rolling linear guide rail, which has higher precision and stability, higher load-bearing capacity, and longer service life compared to existing technologies.

[0004] To achieve the above objectives, this utility model provides a rolling linear guide rail, which includes a guide rail body and a sliding block slidably disposed on the guide rail body. The width of the sliding block is greater than the width of the guide rail body. Sliding wheels are symmetrically disposed on both sides of the bottom of the sliding block, and the sliding wheels roll against the side walls of the guide rail body.

[0005] This utility model provides a rolling linear guide rail. The width of the sliding block of the rolling linear guide rail is greater than that of the guide rail body. The sliding wheels symmetrically arranged on both sides roll closely against the side wall of the guide rail, which can effectively limit the displacement of the sliding block along the width direction of the guide rail. Compared with the prior art, it has better lateral stability, thereby improving the accuracy and load-bearing capacity of the guide rail.

[0006] In one possible implementation, notches are provided on both sides of the guide rail body, and guide strips are installed in the notches. The guide strips have a circular cross-section, and the sliding wheel is attached to the guide strips. The arc-shaped surface of the circular guide strip contacts the sliding wheel, which can guide the sliding block to move more stably along the linear guide rail body.

[0007] In one possible implementation, the sliding wheel has a recessed groove, and the guide bar is disposed within the recessed groove. The guide bar engages within the recessed groove to form a stable motion structure.

[0008] In one possible implementation, four sliding wheels are provided, with two sliding wheels on each side of the sliding block. Having two sliding wheels on each side of the sliding block allows the load to be evenly distributed across the four wheels, improving structural stability.

[0009] In one possible implementation, the sliding block and the sliding wheel are integrally formed. An integrally formed sliding block and sliding wheel structure provides a stronger connection. Attached Figure Description

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0014] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0015] See attached diagram. Figure 1 and Figure 2 As shown in the figure, the present invention provides a rolling linear guide rail including a guide rail body 1 and a sliding block 2 slidably disposed on the guide rail body 1. The width of the sliding block 2 is greater than the width of the guide rail body 1. Sliding wheels 3 are symmetrically disposed on both sides of the bottom of the sliding block 2. The sliding wheels 3 roll against the side walls of the guide rail body 1.

[0016] This utility model provides a rolling linear guide rail. The width of the sliding block 2 of the rolling linear guide rail is greater than that of the guide rail body 1. The sliding wheels 3, which are symmetrically arranged on both sides, roll closely against the side wall of the guide rail, which can effectively limit the displacement of the sliding block 2 along the width direction of the guide rail. Compared with the prior art, it has better lateral stability, thereby improving the accuracy and load-bearing capacity of the guide rail.

[0017] In one possible implementation, notches are provided on both sides of the guide rail body 1, and guide bars 4 are installed in the notches. The cross-section of the guide bars 4 is circular, and the sliding wheel 3 is attached to the guide bars 4. The arc-shaped surface of the circular guide bar 4 contacts the sliding wheel 3, which can guide the sliding block 2 to move more stably along the linear guide rail body 1.

[0018] In one possible implementation, the sliding wheel 3 is provided with a recessed groove 5, and the guide bar 4 is disposed within the recessed groove 5. The guide bar 4 engages within the recessed groove 5 to form a stable motion structure.

[0019] In one possible implementation, four sliding wheels 3 are provided, with two sliding wheels 3 on each side of the sliding block 2. Having two sliding wheels 3 on each side of the sliding block 2 allows the load to be evenly distributed across the four wheels, improving structural stability.

[0020] In one possible implementation, the sliding block 2 and the sliding wheel 3 are integrally formed. The integrally formed sliding block 2 and sliding wheel 3 provide a stronger structural connection.
