Description

Technical Field

[0001] This utility model relates to the field of damper technology, specifically to a miniature linear guide vibration buffer damper device. Background Technology

[0002] Miniature linear guides are significantly smaller than standard linear guides. They are precision linear motion components designed for applications with extremely limited space, light weight requirements, and the need for high-precision linear motion. During use, the movement of the slider on the linear guide will generate vibrations, necessitating the use of dampers to stabilize the slider's movement.

[0003] Existing miniature linear guide vibration damping devices are generally fixed at a specific position on the guide rail or connected to a slider, moving with the slider to buffer and reduce vibration. However, when the damper connected to the slider moves, it is easily affected by dust and other impurities adhering to the guide rail. The damper usually has an adsorption mechanism installed at its end to adsorb dust and other impurities on the linear guide rail. However, some impurities adhere to the guide rail surface, resulting in incomplete adsorption and insufficient cleaning, which reduces the vibration damping effect and improves the overall performance. Furthermore, when replacing the cleaning mechanism on the damper, the damper needs to be removed from the linear guide rail before the cleaning mechanism can be replaced, which is inconvenient.

[0004] Therefore, a miniature linear guide vibration buffer damper device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a miniature linear guide vibration buffer damper device, which can solve the problem of thoroughly cleaning the surface of the linear guide during the movement of the damper.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a miniature linear guide vibration buffer damper, comprising a housing, wherein the housing is slidably sleeved on the linear guide;

[0007] Two mounting plates are symmetrically provided at both ends of the outer shell. The ends of the two mounting plates at the same end abut against each other, and a receiving space is formed between them. A linear guide rail passes through this space. A connecting plate is symmetrically installed at the end of each mounting plate near the outer shell. A pair of grooves are symmetrically opened at both ends of the outer shell. One end of each connecting plate extends into the corresponding groove.

[0008] Each groove is fixedly installed with a screw rod, and one end of each connecting plate is provided with a strip groove. When one end of the connecting plate extends into the corresponding groove, the screw rod is located in the corresponding strip groove, and one end of each screw rod is fitted with a screw sleeve. When the screw sleeve is tightened, one end of the screw sleeve is tightly pressed against the side of the connecting plate.

[0009] Each of the mounting plates has an opening slot inside, and a fixing plate is installed in each opening slot. Several cleaning brushes are installed on the inner surface of the fixing plate, and one end of each cleaning brush is in contact with the surface of the linear guide rail.

[0010] Preferably, an elastic buffer layer is installed on the inner surface of the outer shell, a honeycomb adsorption array is installed on the inner surface of the elastic buffer layer, and a heat-conducting sheet is installed on one side of the honeycomb adsorption array.

[0011] Preferably, the elastic buffer layer is made of polyurethane material.

[0012] Preferably, the heat-conducting sheet is made of copper alloy material.

[0013] Preferably, each of the mounting plates has a plurality of receiving slots at one end, and each of the fixing plates has a plurality of fixing blocks installed at one end. Each fixing block extends into the corresponding receiving slot, and each fixing block is fixed in the receiving slot by bolts.

[0014] Preferably, the outer casing is made of aluminum alloy.

[0015] Preferably, the top of the outer casing has several mounting holes.

[0016] Preferably, wedge-shaped guide rails are installed at both ends of the housing, and a wedge-shaped groove is opened on one side of each mounting plate, with the wedge-shaped groove slidingly fitted onto the corresponding wedge-shaped guide rail.

[0017] Compared with the prior art, this utility model provides a miniature linear guide vibration buffer damper device, which has the following beneficial effects:

[0018] 1. By fixing the mounting plate to the housing, multiple cleaning brushes on the mounting plate can contact the surface of the linear guide. When the housing moves with the slider on the linear guide, the multiple cleaning brushes can simultaneously clean the surface of the linear guide, removing dust and other impurities. This thorough cleaning prevents the damper from being affected by dust or impurities, thus improving the performance.

[0019] 2. The mounting plate can be fixed to the end of the housing by tightening the screw sleeve. When the cleaning brush needs to be replaced, simply unscrew the screw sleeve from the screw rod and pull the mounting plate to remove the mounting plates located at both ends of the housing, thereby separating the cleaning brush from the housing for replacement. There is no need to remove the entire housing from the linear guide rail, making replacement convenient. Attached Figure Description

Detailed Implementation

[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] Example:

[0028] Please see Figure 1 - Figure 5 This embodiment of a miniature linear guide vibration damper includes a housing 1, which is slidably fitted onto the guide rail. The top of the housing 1 has several mounting holes 13. The housing 1 is made of aluminum alloy. In actual use, the housing 1 can be fitted onto the linear guide rail, such that the housing 1 is positioned between two sliders and below a movable plate connecting the tops of the two sliders. Figure 5 As shown, the bolts on the movable plate are matched with the mounting holes 13 to connect the outer shell 1 to the two sliders, thus completing the installation.

[0029] like Figure 4As shown, an elastic buffer layer 16 is installed on the inner surface of the outer shell 1. The elastic buffer layer 16 is made of polyurethane material. In actual use, the vibration generated by the movement of the slider will be transmitted to the outer shell 1 through the moving plate. At this time, the elastic buffer layer 16 will deform under the vibration, converting the force generated by the vibration into the elastic potential energy of the deformation, and thus absorbing the vibration of the slider.

[0030] like Figure 4 As shown, a honeycomb adsorption array 15 is installed on the inner surface of the elastic buffer layer 16. During use, the vibration generated by the movement of the slider will be transmitted to the outer shell 1 through the moving plate. The honeycomb adsorption array 15 can convert the received vibration into internal energy, thereby reducing the vibration received by the slider when it moves.

[0031] like Figure 4 As shown, a heat-conducting plate 14 is installed on one side of the honeycomb adsorption array 15. The heat-conducting plate 14 is made of copper alloy material, or other materials with good thermal conductivity. When the damper moves with the slider, it will generate heat. This heat can be quickly dissipated into the surrounding environment through the heat-conducting plate 14, thereby avoiding the damper temperature from being too high and affecting the effect.

[0032] like Figure 1 and Figure 3 As shown, two mounting plates 5 are symmetrically provided at both ends of the outer shell 1. The ends of the two mounting plates 5 located at the same end abut against each other, and a receiving space is formed between them. A linear guide rail passes through this space. A connecting plate 4 is symmetrically installed on the end of the mounting plate 5 near the outer shell 1. A pair of grooves 2 are symmetrically opened at both ends of the outer shell 1. One end of each connecting plate 4 extends into the corresponding groove 2. In actual use, the mounting plate 5 can be limited by the cooperation between the connecting plate 4 and the groove 2, so that the connection between the mounting plate 5 and the outer shell 1 is more stable.

[0033] It should be noted that, as Figure 2 and Figure 3 As shown, wedge-shaped guide rails 17 are installed at both ends of the outer shell 1, and a wedge-shaped groove 18 is opened on one side of each mounting plate 5. The wedge-shaped groove 18 slides on the corresponding wedge-shaped guide rail 17. Through the cooperation of the wedge-shaped guide rail 17 and the wedge-shaped groove 18, the mounting plate 5 can be limited, making the mounting plate 5 more stable.

[0034] like Figure 1 As shown, each groove 2 is fixedly installed with a screw 3, and one end of each connecting plate 4 is provided with a strip groove 12. When one end of the connecting plate 4 extends into the corresponding groove 2, the screw 3 is located in the corresponding strip groove 12, and one end of each screw 3 is fitted with a screw sleeve 11. When the screw sleeve 11 is tightened, one end of the screw sleeve 11 is tightly pressed against the side of the connecting plate 4. By tightening the screw sleeve 11, the connecting plate 4 can be fixed in the groove 2, so that the mounting plate 5 and the outer shell 1 can be fixed together.

[0035] like Figure 1 and Figure 3 As shown, each mounting plate 5 has an opening groove 7 inside, and each opening groove 7 has a fixing plate 9. Several cleaning brushes 10 are installed on the inner surface of the fixing plate 9. One end of each cleaning brush 10 is in contact with the surface of the linear guide rail. In actual use, as the outer shell 1 moves with the slider, it will drive the mounting plate 5 to move. The mounting plate 5 will drive the fixing plate 9 to move, so that the cleaning brushes 10 will move along the linear guide rail. While moving, they will clean the dust and other impurities on the linear guide rail to prevent the damper from being affected.

[0036] like Figure 1 and Figure 3 As shown, each mounting plate 5 has several receiving grooves 6 at one end, and each fixing plate 9 has several fixing blocks 8 at one end. Each fixing block 8 extends into the corresponding receiving groove 6, and each fixing block 8 is fixed in the receiving groove 6 by bolts. Through the cooperation of the fixing block 8 and the receiving groove 6, the fixing plate 9 can be limited, making the connection between the fixing plate 9 and the outer shell 1 more stable.

[0037] The working principle of the above embodiments is as follows:

[0038] In use, first align the connecting plate 4 on the mounting plate 5 with the grooves 2 at both ends of the outer casing 1, and simultaneously align the wedge groove 18 with the wedge guide rail 17 at the end of the outer casing 1. Then move the mounting plate 5 so that the wedge groove 18 fits onto the wedge guide rail 17. When the ends of the two mounting plates 5 abut, the connecting plate 4 is inserted into the corresponding groove 2. At the same time, the strip groove 12 on the connecting plate 4 fits onto the side of the screw 3. Then, the operator tightens the screw sleeve 11, which fixes the connecting plate 4 in the groove 2, securing the mounting plate 5 and the outer casing 1 together. Then, the outer casing 1 is placed on the linear guide rail. At this time, several cleaning brushes 10 are in contact with the surface of the linear guide rail. The outer casing 1 is located between two sliders on the linear guide rail. The sliders on the linear guide rail and the outer casing 1 are fixed to the moving plate with bolts. During movement, the sliders are subjected to vibrations that are similar to those experienced by the sliding plate. The vibration is transmitted to the outer casing 1, which in turn causes the internal elastic buffer layer 16 and honeycomb adsorption array 15 to vibrate synchronously. At this time, the elastic buffer layer 16 and honeycomb adsorption array 15 can buffer the vibration, thereby reducing the vibration when the slider moves. When the outer casing 1 moves with the slider, it will synchronously drive the mounting plate 5 to move. The mounting plate 5 drives the fixing plate 9 to move. The fixing plate 9 drives the cleaning brush 10 to move along the linear guide rail. During the movement, several cleaning brushes 10 can clean the impurities on the linear guide rail. In this way, the damper will not be affected by impurities when it moves, thus improving the performance. When it is necessary to replace the cleaning brush 10, simply unscrew the sleeve 11 from the screw 3 and then pull the mounting plate 5 to remove the mounting plate 5 from the outer casing 1. There is no need to remove the entire outer casing 1 from the linear guide rail for replacement, making replacement convenient.

[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0040] 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.
