Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, specifically to an arc guide rail. Background Technology

[0002] A guide rail is a mechanical structure that guides an object to move precisely and smoothly along a specific path, such as a straight line or a curve. The most common type is the ball bearing guide rail.

[0003] Traditional guide rails are mostly linear. After long-term use, the friction on the guide rail surface will increase due to the continuous rolling of balls. Therefore, it is necessary to stop work regularly to maintain the guide rail. However, stopping work will reduce work efficiency. In addition, the angle of the linear guide rail is fixed and cannot adapt to more usage needs. Furthermore, traditional guide rails lack an active dust cleaning structure, which causes dust to accumulate inside the slide groove and affect the movement of the slider. Therefore, a circular arc guide rail is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a circular arc guide rail to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an arc-shaped guide rail, comprising a track, the track having an arc-shaped structure, and grooves formed on both the front and rear surfaces of the track. Positioning cones and positioning cone holes are respectively provided at the left and right ends of the track, and the positioning cones and positioning cone holes have the same taper. A fixing plate integrally connected to the track is provided on the outer side of both the positioning cones and positioning cone holes, and the fixing plate is connected to the bottom of the track.

[0006] A slider is provided above the track, and the slider is pre-loaded with ball bearings. A carrier plate is connected to the upper surface of the slider.

[0007] The bottom of the carrier plate is equipped with a guide rail dust removal mechanism. The left and right sections of the carrier plate are hollow, and the interior of each of the two hollow sections is equipped with a dust filtration system. The left and right ends of the upper surface of the track are equipped with limit buffer components.

[0008] Preferably, the guide rail cleaning mechanism includes a first connecting pipe and a second connecting pipe. Two sets of the first connecting pipe and the second connecting pipe are arranged on the lower surface of the carrier plate. The two sets of the first connecting pipe and the second connecting pipe are symmetrically arranged about the slider. A miniature air pump built into the carrier plate is installed at the top of the first connecting pipe and the second connecting pipe.

[0009] Preferably, both the first connecting pipe and the second connecting pipe have an arc-shaped structure, and the output ends of the first connecting pipe and the second connecting pipe are flush with the slide groove.

[0010] Preferably, the dust filtration system includes a pull-out box, a first through hole, a second through hole, and a filter element. The pull-out box is inserted inside the carrier plate, and the outer surface of the pull-out box has the first through hole and the second through hole pre-drilled. The filter element is detachably connected inside the pull-out box.

[0011] Preferably, a pull rod is installed on one end surface of the pull-out box near the first through hole, and a magnet is embedded in and connected to the upper surface of the pull-out box.

[0012] Preferably, the limiting buffer assembly includes a limiting plate, a rubber pad, and a fixing hole. The limiting plate is connected to the bottom outer surface of the track, and the rubber pad is connected to the side surface of the limiting plate facing the carrier plate. The fixing hole is provided at the bottom of the limiting plate.

[0013] Preferably, a pressure sensor is installed inside the rubber pad, and the pressure sensor is connected to the outer surface by a wireless transmission module placed inside the limiting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This circular arc guide rail is designed to be divided into multiple parts, which facilitates quick disassembly, maintenance and replacement, reducing maintenance costs. At the same time, as long as the overall structural parts remain unchanged, the angle can be flexibly adjusted by changing the curvature between different rails.

[0016] 2. This arc guide rail uses tapered positioning posts and positioning holes, so that during installation and splicing, the staff does not need to carefully find the position. They only need to insert the positioning post into the positioning hole, and as the two rails continue to move closer together, high-precision positioning can be automatically completed.

[0017] 3. This arc-shaped guide rail, through the cooperation between the guide rail cleaning mechanism and the dust filtration system, can blow out clean airflow to continuously clean the surface of the slide rail; by installing impact detection parts in the limit buffer assembly, it is possible to monitor in real time whether the drive assembly of the slider is malfunctioning.

They are used only for the convenience of describing this utility model 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 utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Example 1

[0027] like Figures 1 to 4As shown, the arc guide rail in this embodiment includes a track 1, which has an arc-shaped structure and grooves 2 on both the front and rear surfaces. By dividing a complete guide rail into multiple parts, it is possible to quickly disassemble, maintain, and replace it. At the same time, it is more flexible in terms of angle. As long as the overall structure remains unchanged, the curvature of the track 1 can be slightly changed. The left and right ends of the track 1 are respectively provided with positioning cones 3 and positioning cone holes 4, and the positioning cones 3 and positioning cone holes 4 have the same taper. By setting the positioning cones 3 and positioning cone holes 4, when multiple tracks 1 are spliced, the staff does not need to accurately find the position. They can simply insert the positioning cones 3 into the positioning cone holes 4. Then, during the process of the two tracks 1 coming close together, under the combined action of the radial component forces generated by multiple contact points, the positioning cones 3 will be "corrected" to a position that is completely coaxial with the positioning cone holes 4. Finally, the center lines of the two parts coincide, the contact area reaches the maximum, and high-precision positioning is achieved. The outer sides of the positioning cone 3 and the positioning cone hole 4 are provided with fixing plates 11 that are integrally connected with the track 1. The fixing plates 11 are connected to the bottom of the track 1. After positioning is completed, the fixing plates 11 on the two tracks 1 are fixed by bolts, so that the two tracks 1 can be fixed.

[0028] A slider 5 is installed above the track 1, and the slider 5 is pre-loaded with ball bearings. A carrier plate 6 is connected to the upper surface of the slider 5. The carrier plate 6 is made of a magnetic material like iron. The slider 5 moves on the track 1 under the control of the corresponding drive components and carries and transports items through the carrier plate 6.

[0029] The bottom of the carrier plate 6 is provided with a guide rail cleaning mechanism 7. The left and right sections of the carrier plate 6 are hollow, and the interior of each of the two hollow sections is provided with a dust filtration system 8. The guide rail cleaning mechanism 7 can clean the interior of the slide 2 in real time to prevent dust from affecting the sliding of the slider 5. The dust filtration system 8 can prevent the airflow blown out by the guide rail cleaning mechanism 7 from containing dust. The upper surface of the track 1 is provided with limit buffer components 12 at both ends. The limit buffer components 12 buffer and limit the slider 5 that slides to the end of the track 1.

[0030] Furthermore, the guide rail dust removal mechanism 7 includes a first connecting pipe 701 and a second connecting pipe 702. Two sets of the first connecting pipe 701 and the second connecting pipe 702 are arranged on the lower surface of the carrier plate 6. The two sets of the first connecting pipe 701 and the second connecting pipe 702 are symmetrically arranged about the slider 5. A miniature air pump built into the carrier plate 6 is installed at the top of the first connecting pipe 701 and the second connecting pipe 702. The miniature air pump draws air, so that the airflow blows out through the first connecting pipe 701 and the second connecting pipe 702 to clean the dust inside the slide groove 2.

[0031] Furthermore, both the first connecting pipe 701 and the second connecting pipe 702 have an arc-shaped structure, and the output ends of the first connecting pipe 701 and the second connecting pipe 702 are flush with the slide groove 2, thus ensuring that the airflow blown out by the first connecting pipe 701 and the second connecting pipe 702 is exactly aligned with the slide groove 2.

[0032] Furthermore, the dust filtration system 8 includes a pull-out box 801, a first through hole 802, a second through hole 803, and a filter element 804. The pull-out box 801 is inserted inside the carrier plate 6. The outer surface of the pull-out box 801 has the first through hole 802 and the second through hole 803. The filter element 804 is detachably connected inside the pull-out box 801. The pull-out box 801 can be pulled out from inside the carrier plate 6 to replace the filter element 804. When the micro air pump is working, outside air enters through the first through hole 802 and is filtered by the filter element to remove dust. Then, it enters the first connecting pipe 701 and the second connecting pipe 702 through the second through hole 803 and the micro air pump, and is finally blown out.

[0033] Furthermore, a pull rod 9 is installed on one end of the pull-out box 801 near the first through hole 802, and a magnet 10 is embedded in the upper surface of the pull-out box 801. By pulling the pull rod 9, the pull-out box 801 can be moved, and the magnetic attraction between the magnet 10 and the carrier plate 6 can keep the pull-out box 801 stable.

[0034] The method of use in this embodiment is as follows: During assembly, the positioning cones 3 and positioning cone holes 4 on the two tracks 1 are connected. Under the combined action of the radial components generated by multiple contact points, the positioning cones 3 will be "corrected" to a position that is completely coaxial with the positioning cone holes 4. Finally, the center lines of the two parts coincide, achieving high-precision positioning. After positioning, the fixing plates 11 on the two tracks 1 are fixed with bolts to fix the two tracks 1. At this time, the slider 5 can be installed. When the slider 5 moves the carrier plate 6, the guide rail cleaning mechanism 7 and the dust filtering system 8 can be used to continuously clean the surface of the slide 2, preventing dust from adhering and affecting the movement of the slider 5.

[0035] Example 2

[0036] Based on Example 1, such as Figure 5 As shown, an arc guide rail also includes a limiting and buffering assembly 12, which includes a limiting plate 1201, a rubber pad 1202, and a fixing hole 1203. The limiting plate 1201 is connected to the bottom outer surface of the rail 1. The rubber pad 1202 is connected to the side surface of the limiting plate 1201 facing the carrier plate 6. The fixing hole 1203 is opened at the bottom of the limiting plate 1201. When the slider 5 slides to the end of the rail 1, it will contact the rubber pad 1202, thereby buffering and limiting.

[0037] Furthermore, a pressure sensor is installed inside the rubber pad 1202, and the pressure sensor is connected to the outer surface by a wireless transmission module placed inside the limit plate 1201. When the slider 5 slides and impacts the rubber pad 1202, the impact force can be measured by the pressure sensor and the data can be transmitted through the wireless transmission module.

[0038] The usage method of this embodiment is as follows: The limiting plate 1201 is fixed to the track 1 by bolts. When the slider 5 slides to the end of the track 1, it will contact the rubber pad 1202 to buffer and limit the movement. At the same time, the impact force is measured by the pressure sensor and transmitted through the wireless transmission module. Since the slider 5 moves at a constant speed, the impact force value will be the same or have a very small error each time. When it is found that the difference between the detected values ​​is too large, it can be known that the drive mechanism of the slider 5 has failed.

[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
