Description

Technical Field

[0001] This utility model relates to the field of aluminum guide rail technology, and in particular to a lightweight aluminum guide rail. Background Technology

[0002] As a key mechanical component that guides and supports moving parts to move in a straight or curved path, the performance of the guide rail directly affects the overall efficiency and accuracy of the equipment.

[0003] While pursuing lightweight design to reduce weight, save costs and improve energy efficiency, guide rails must also ensure that they can provide quiet and stable motion support. To meet this requirement, existing aluminum guide rails usually achieve the goal of lightweighting by changing the thickness and structural form, but this greatly limits the performance of guide rails in terms of quietness and stability.

[0004] While significant progress has been made in weight reduction with aluminum guide rails currently available on the market, they still face the following challenges in practical applications:

[0005] First, existing lightweight technologies are often accompanied by noise problems, especially in high-speed or high-dynamic response scenarios, where the vibration and noise of the guide rail may seriously affect the stability and concealment of the equipment.

[0006] Secondly, the simple method of adjusting the structure and thickness fails to fully consider the dynamic response characteristics of the guide rail under stress, which may lead to significant instability in actual operation. Especially under asynchronous loads and large environmental changes, the movement of the guide rail may become unstable, affecting the overall performance of the equipment.

[0007] Given the above background, we propose a lightweight aluminum guide rail that ensures sufficiently quiet movement of moving parts and improved stability. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by proposing a design scheme that achieves lightweight design while maintaining quietness and stability, and optimizes the performance of guide rail materials and structures.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A lightweight aluminum guide rail includes an aluminum guide rail body. The aluminum guide rail body has guide rail grooves symmetrically arranged on the shorter side. Limiting frames are provided on both sides of the guide rail grooves along the length direction. A hollow square groove is opened in the aluminum guide rail body along the length direction. Inclined surfaces are provided at both ends of the upper part of the limiting frames.

[0011] The thickness of the aluminum guide rail body, guide rail groove, and longer side is 1.5mm-4mm;

[0012] A snap-fit ​​bracket is provided in the guide rail groove at one end of the shorter side of the hollow square groove. A T-shaped bracket is snapped into the snap-fit ​​bracket. Sound-absorbing pads are filled between the two sides of the T-shaped bracket and the hollow square groove.

[0013] Furthermore, the angle between the inclined surface on one side and the guide rail groove is 100°-135°, and the inclined surface on the other side is inclined towards the outside of the aluminum guide rail body.

[0014] Furthermore, the limiting frame has lightweight slots formed along its length.

[0015] Furthermore, the snap-fit ​​brackets are symmetrically arranged on both sides of the hollow square groove near one end, forming a snap-fit ​​groove between them.

[0016] Furthermore, the T-shaped bracket is made of aluminum alloy or PC plastic. After the T-shaped bracket is inserted into the snap-fit ​​groove, its upper and lower ends of the horizontal part are respectively attached to the inner wall of the hollow square groove and the snap-fit ​​frame.

[0017] Furthermore, the upper end of the horizontal part of the T-shaped bracket is provided with a shock-absorbing pad, which is made of rubber.

[0018] Furthermore, the sound-absorbing pad is made of porous aluminum foam with an internal porosity of 60%-80%.

[0019] Furthermore, a lightweight groove is formed along the length direction on the outer side of the longer side of the aluminum guide rail body.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The space between the T-shaped bracket and the hollow square channel is filled with a sound-absorbing pad made of porous aluminum foam. Its high porosity (60%-80%) effectively absorbs and reduces the noise generated during the movement of the guide rail. Especially in high-speed or high-dynamic response scenarios, it significantly reduces the impact of vibration and noise on the stability and concealment of the equipment, thereby reducing the offset and shaking during the movement process.

[0022] After the T-shaped bracket is inserted into the slot, its upper and lower ends of the horizontal part are respectively attached to the inner wall of the hollow square slot and the slot frame, which enhances the overall structural strength of the guide rail and improves stability. (Note: The horizontal part of the T-shaped bracket here corresponds to the upper guide rail slot, while the bottom guide rail slot does not play a force-bearing role, so there is no need for side support.)

[0023] The rubber shock-absorbing pads installed at the upper part of the horizontal section of the T-shaped bracket further absorb the impact force generated by the moving parts, reduce the vibration of the guide rail, and thus improve stability.

[0024] Based on the above-mentioned noise reduction and stability adaptation design, and with certain improvements, compared with the existing lightweight aluminum guide rail thickness (generally 2mm-6mm), the thickness of this aluminum guide rail body, guide rail groove and longer side is 1.5mm-4mm. Under the same design requirements (stability, noise level), this aluminum guide rail can adaptively reduce the thickness to achieve better performance.

[0025] In summary, the overall structure of this aluminum guide is reasonably designed, achieving both the goal of lightweighting and ensuring the quietness and stability of the guide rail, thereby improving the overall performance and reliability of the equipment. Attached Figure Description

[0041] Example 1

[0042] like Figure 1-4 As shown, this utility model provides a technical solution: a lightweight aluminum guide rail. The core design of this aluminum guide rail aims to achieve lightweighting while ensuring the quietness and stability of moving parts. The guide rail includes: an aluminum guide rail body 1, with guide rail grooves 2 symmetrically arranged on its shorter side; limit frames 3 are provided on both sides of the guide rail groove 2 along the length direction to guide and support the stable movement of moving parts; a hollow square groove 4 is opened inside the aluminum guide rail body 1 along the length direction, which significantly reduces the overall weight of the guide rail; inclined surfaces 31 are provided at both ends above the limit frames 3, which helps to reduce friction and resistance of moving parts on the guide rail;

[0043] The thickness of the aluminum guide rail body 1, guide rail groove 2, and the longer side is controlled between 2mm and 4mm, which ensures the strength of the guide rail and achieves the goal of lightweighting. The shorter side of the hollow square groove 4 is provided with a snap-fit ​​bracket 5 corresponding to one end of the guide rail groove 2, which is used to snap-fit ​​the T-shaped bracket 6. The two sides of the T-shaped bracket 6 and the hollow square groove 4 are filled with sound-absorbing pads 7, which effectively absorb and reduce the noise generated when the guide rail moves.

[0044] Example 2

[0045] like Figure 1-4 As shown, the details are further refined based on Example 1:

[0046] First, the inclined surface 31 is designed with an angle of 100°-135° between one inclined surface 31 and the guide rail groove 2. This angle range has been carefully calculated to provide stable guidance and reduce the jamming of moving parts on the guide rail. The other inclined surface 31 is inclined towards the outside of the aluminum guide rail body 1 for lightweight design and to reduce the overall weight.

[0047] Secondly, the limit frame 3 is lightweight: lightweight slots 32 are provided inside the limit frame 3 along the length direction, which further reduces the weight of the guide rail while maintaining the strength and stability of the limit frame 3.

[0048] Regarding the fit between the snap-fit ​​bracket 5 and the T-shaped bracket 6: The snap-fit ​​bracket 5 is symmetrically arranged on both sides of the hollow square groove 4 near one end, forming a snap-fit ​​groove 51 between them. The T-shaped bracket 6 is made of aluminum alloy or PC plastic, which has the characteristics of light weight and high strength. After the T-shaped bracket 6 is snapped into the snap-fit ​​groove 51, its upper and lower ends of the horizontal part are respectively in contact with the inner wall of the hollow square groove 4 and the snap-fit ​​bracket 5, ensuring the overall structural strength of the guide rail.

[0049] Among them, the upper part of the horizontal section of the T-shaped bracket 6 is provided with a shock-absorbing pad 61, which is made of rubber material and can effectively absorb the impact force generated by the moving parts, reducing the vibration and noise of the guide rail.

[0050] Finally, the sound-absorbing pad 7 is made of porous aluminum foam with an internal porosity of 60%-80%. This high porosity structure gives the sound-absorbing pad 7 excellent sound absorption performance, further reducing noise during the movement of the guide rail.

[0051] It should be added that, in order to further reduce the weight of the aluminum guide rail body 1, a lightweight groove 11 is provided on the outer side of the longer side of the aluminum guide rail body 1 along the length direction. This design not only reduces the weight of the guide rail, but also improves the heat dissipation performance of the guide rail.

[0052] Workflow: When using the lightweight aluminum guide rail of this utility model, first follow these steps for installation and use:

[0053] ① Preparation of the guide rail body: Place the aluminum guide rail body 1 in the equipment installation position according to the design requirements, ensuring that the guide rail groove 2 is aligned with the movement path of the moving parts, and then the moving wheels are engaged in the guide rail groove 2, with the upper guide rail groove 2 bearing the force;

[0054] ② T-shaped bracket 6 installation: T-shaped bracket 6 is inserted into the snap-fit ​​groove 51, ensuring that the upper and lower ends of the horizontal part of T-shaped bracket 6 are tightly fitted with the inner wall of the hollow square groove 4 and the snap-fit ​​frame 5 respectively. Check whether T-shaped bracket 6 is installed firmly and without looseness, and whether it corresponds to the force-bearing end of the upper guide rail groove 2 and provides support.

[0055] ③ Sound-absorbing pad 7 filling: Fill the space between the two sides of the T-shaped bracket 6 and the hollow square groove 4 with sound-absorbing pad 7, ensuring that the sound-absorbing pad 7 is filled evenly and without gaps. The filling of the sound-absorbing pad 7 can effectively absorb and reduce the noise generated when the guide rail moves.

[0056] ④ Installation of moving parts: Install the moving parts in the guide rail groove 2, ensuring that the fit clearance between the moving parts and the guide rail groove 2 is appropriate and there is no jamming. Check whether the movement of the moving parts on the guide rail is smooth and stable.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
