Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, specifically to a multi-segment S-shaped arc guide rail with anti-detachment connection. Background Technology

[0002] In fields such as automated production, logistics transportation, and precision instruments, curved guide rails are key structures for enabling component turning and meandering movements, and their stability and flexibility directly affect the overall operating efficiency of the equipment.

[0003] Traditional curved guide rails are mostly integral structures. While they can meet the basic requirements of curved motion, they are difficult and costly to manufacture when facing complex multi-turn scenarios. Furthermore, if a part of the rail is damaged, the entire rail needs to be replaced, resulting in high maintenance costs. To adapt to complex scenarios, some multi-segment curved guide rails have emerged. However, their connection structure has obvious defects: in the horizontal direction, they rely heavily on rigid bolt connections, resulting in low positioning accuracy during installation. Over long-term use, the bolts are prone to loosening due to vibration, causing the guide rail to shift or even fall off. In the vertical direction, they lack reliable limiting, making them prone to vertical swaying during operation and affecting the sliding stability of the components.

[0004] In addition, the disassembly and maintenance of existing multi-section guide rails are extremely cumbersome, often requiring the removal of multiple connecting parts to take off a single section of the guide rail, which seriously affects equipment downtime and production efficiency. Against this background, it is urgent to develop a multi-section arc-shaped guide rail that is stable in connection, easy to disassemble, and adaptable to complex scenarios. The multi-section S-shaped arc-shaped guide rail with anti-detachment connection of this application has emerged to solve the problems of traditional guide rails. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-segment S-shaped arc guide rail with anti-detachment connection. By setting a sliding insertion structure between the base plate and the arc guide rail, an adsorption cooperation between the magnetic plate and the metal plug, and a limiting mechanism, the problem of easy detachment, inconvenient disassembly, and overall removal required for maintenance of the multi-segment S-shaped arc guide rail is solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The anti-detachment multi-segment S-shaped arc guide rail includes a base plate. Several arc guide rails, arranged from left to right and sequentially joined together, are slidably inserted into the top surface of the base plate. The arc guide rails are S-shaped, and their top surfaces are provided with grooves that conform to their shape. The longitudinal cross-sectional shape of the grooves on the top surface of the arc guide rails is convex. The system also includes:

[0008] A limiting mechanism is installed on the top surface of the base plate near the rear end to limit the movement of several arc-shaped guide rails. The limiting mechanism includes a U-shaped plate fixed on the top surface of the base plate, a movable plate slidably connected to the bottom surface of the horizontal end of the U-shaped plate, a screw rotatably connected between the two vertical ends of the U-shaped plate and used to drive the movable plate to move back and forth, a mounting plate fixed on the right side surface of the movable plate, and limiting rods fixed on the front side surface of the mounting plate and slidably inserted into several arc-shaped guide rails respectively.

[0009] In a preferred embodiment, the U-shaped plate is fixed to the top surface of the base plate near the left end and is arranged from front to back. The limiting mechanism also includes two rotating columns that are rotatably connected to the two vertical ends of the U-shaped plate respectively. The screw is coaxially fixed between the two rotating columns and is arranged from front to back. The moving plate is threadedly connected to the screw.

[0010] In a preferred embodiment, the limiting mechanism further includes a motor mounted on the surface of one of the vertical plates of the U-shaped plate away from the screw, and the output shaft of the motor is coaxially connected to the rotating column on the same side.

[0011] In a preferred embodiment, the outer wall of the arc-shaped guide rail is provided with a limiting hole, and the limiting rod is slidably inserted into the limiting hole on the outer wall of the arc-shaped guide rail on the same side.

[0012] In a preferred embodiment, the limiting mechanism further includes a U-shaped guide plate fixed to the top surface of the base plate near the right end, a guide rod rotatably connected between the two vertical ends of the guide plate and slidably inserted into the mounting plate, a guide groove arranged from front to back on the bottom surface of the horizontal end of the U-shaped plate, and a guide block slidably connected to the guide groove on the bottom surface of the horizontal end of the U-shaped plate fixed on the top surface of the moving plate.

[0013] In a preferred embodiment, the longitudinal cross-sectional shape of the guide groove on the bottom surface of the U-shaped plate is convex, and the shape of the guide block is convex, which is adapted to the shape of the guide groove on the bottom surface of the U-shaped plate.

[0014] These five settings enable the movable plate to move stably back and forth, provide a basis for the movement of the limit rod, make the screw rotation more convenient and labor-saving, improve the operating efficiency of the limit mechanism, make the limit rod's limit on the arc guide rail more precise and stable, make the movable plate move more smoothly and avoid deviation, and make the guide block slide more stably in the guide groove and prevent it from falling off.

[0015] In a preferred embodiment, the top surface of the base plate is provided with a plurality of mounting holes arranged in a matrix, the top surface of the base plate is provided with a plurality of slots, and the bottom surface of the arc-shaped guide rail is fixed with two plug blocks that slide into the slots on the same side of the top surface of the base plate.

[0016] In a preferred embodiment, the insert is made of metal, and magnetic plates are installed on the inner bottom surfaces of several slots on the top surface of the base plate. The insert is attached to the top surface of the magnetic plate on the same side and is attracted to the magnetic plate by magnetic force.

[0017] These two features make it easy to fix the base plate, and the sliding connection between the arc-shaped guide rail and the base plate makes the connection between the two more stable, making the horizontal limit of the arc-shaped guide rail more reliable. At the same time, it simplifies the installation and disassembly process and facilitates individual maintenance.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model features a slot on the top surface of the base plate and a block on the bottom surface of the arc-shaped guide rail that slides into the slot. A magnetic absorbing plate is installed on the bottom surface of the slot. The magnetic attraction between the magnetic absorbing plate and the block effectively limits the horizontal movement of several arc-shaped guide rails. This design makes guide rail installation more convenient and ensures the horizontal stability of the arc-shaped guide rails during use, achieving both easy installation and horizontal stability.

[0020] 2. This utility model, through the setting of a limiting mechanism, in which components such as a U-shaped plate, screw, moving plate, mounting plate, and limiting rod cooperate with each other, the rotation of the screw can drive the moving plate to move the limiting rod back and forth, thereby achieving vertical limiting of several arc-shaped guide rails. Combined with horizontal limiting, it facilitates the disassembly, maintenance, or repair of one or more of the several arc-shaped guide rails without having to disassemble the entire guide rail, achieving the effect of convenient maintenance and reduced maintenance costs and time. At the same time, the multiple S-shaped arc-shaped guide rails, through segmented design and precise connection, can be flexibly combined into a continuous "S" shaped curve trajectory, which can perfectly adapt to complex motion scenarios requiring multiple turns and detours, meeting diverse usage needs.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] Please see Figures 1-2 The present invention provides a technical solution: a multi-segment S-shaped arc guide rail with anti-detachment connection, including a base plate 1. Several arc guide rails 2 are slidably inserted on the top surface of the base plate 1, arranged from left to right and spliced ​​together in sequence. The arc guide rails 2 are S-shaped. The top surface of the arc guide rails 2 is provided with a groove that matches its shape, and the longitudinal cross-sectional shape of the groove on the top surface of the arc guide rails 2 is convex.

[0029] Several S-shaped arc guide rails 2 are slidably inserted into the base plate 1. The top surface of the arc guide rail 2 is provided with a convex groove, which allows the guide rails to be flexibly combined into a continuous S-shaped trajectory to adapt to complex motion scenarios. At the same time, the convex groove can enhance the stability of the sliding parts and prevent them from falling off.

[0030] The top surface of the base plate 1 has several mounting holes arranged in a matrix, and the top surface of the base plate 1 has several slots. The bottom surface of the arc-shaped guide rail 2 has two plug blocks 21 that slide and insert into the slots on the same side of the top surface of the base plate 1.

[0031] The base plate 1 is provided with mounting holes and slots, and the bottom surface of the arc-shaped guide rail 2 is provided with insert blocks 21, which makes it easy to fix the base plate 1. The arc-shaped guide rail 2 and the base plate 1 are slidably inserted into each other for more stable installation and more accurate positioning during installation.

[0032] The insert 21 is made of metal. Magnetic plates 11 are installed on the inner bottom surface of several slots on the top surface of the base plate 1. The insert 21 is attached to the top surface of the magnetic plate 11 on the same side and is attracted to the magnetic plate 11 by magnetic attraction.

[0033] The metal insert 21 is attracted to the magnetic piece 11 in the slot of the base plate 1, which enhances the horizontal limiting effect of the arc-shaped guide rail 2, while simplifying the installation and disassembly steps, making it easy to disassemble and maintain individually without the need for complete removal.

[0034] In this embodiment, as Figures 1-4As shown, it also includes: a limiting mechanism 3, which is set on the top surface of the base plate 1 near the rear end, for limiting several arc-shaped guide rails 2. The limiting mechanism 3 includes a U-shaped plate 31 fixed on the top surface of the base plate 1, a moving plate 34 slidably connected to the bottom surface of the horizontal plate end of the U-shaped plate 31, a screw 33 rotatably connected between the two vertical plate ends of the U-shaped plate 31 and used to drive the moving plate 34 to move back and forth, a mounting plate 36 fixed on the right side surface of the moving plate 34, and a limiting rod 37 fixed on the front side surface of the mounting plate 36 and slidably inserted into several arc-shaped guide rails 2 respectively.

[0035] The U-shaped plate 31 is fixed on the top surface of the base plate 1 near the left end and is arranged from front to back. The limiting mechanism 3 also includes two rotating columns 32 that are rotatably connected to the two vertical ends of the U-shaped plate 31 respectively. The screw 33 is coaxially fixed between the two rotating columns 32 and is arranged from front to back. The moving plate 34 is threadedly connected to the screw 33.

[0036] Through the cooperation of U-shaped plate 31, rotating column 32, screw 33 and moving plate 34, rotating column 32 supports screw 33 to rotate, and moving plate 34 is threadedly connected to screw 33, so that moving plate 34 can move back and forth smoothly, providing a stable foundation for the movement of limit rod 37.

[0037] The limiting mechanism 3 also includes a motor 310 installed on the surface of one of the vertical plates of the U-shaped plate 31 away from the screw 33, and the output shaft of the motor 310 is coaxially connected to the rotating column 32 on the same side.

[0038] The motor 310 is installed at the vertical end of the U-shaped plate 31, and its output shaft is connected to the rotating column 32, so that the screw 33 can rotate without manual operation, saving manpower, improving the adjustment efficiency of the limit mechanism 3, and making operation more convenient.

[0039] The outer wall of the arc-shaped guide rail 2 is provided with a limiting hole, and the limiting rod 37 is slidably inserted into the limiting hole on the outer wall of the arc-shaped guide rail 2 on the same side.

[0040] The outer wall of the arc-shaped guide rail 2 is provided with a limiting hole, and the limiting rod 37 is slidably inserted into the limiting hole, so that the limiting rod 37 can be accurately embedded in the arc-shaped guide rail 2, which makes it more secure in the vertical direction and prevents it from shaking or falling off during use.

[0041] The limiting mechanism 3 also includes a U-shaped guide plate 38 fixed on the top surface of the base plate 1 near the right end, a guide rod 39 rotatably connected between the two vertical ends of the guide plate 38 and slidably inserted into the mounting plate 36, a guide groove arranged from front to back on the bottom surface of the horizontal end of the U-shaped plate 31, and a guide block 35 fixed on the top surface of the moving plate 34 and slidably connected to the guide groove on the bottom surface of the horizontal end of the U-shaped plate 31.

[0042] By adding a U-shaped guide plate 38 and a guide rod 39 to the limiting mechanism 3, and combining the guide groove of the U-shaped plate 31 with the guide block 35 of the moving plate 34, the mounting plate 36 and the moving plate 34 move more smoothly, preventing deviation and improving the limiting accuracy.

[0043] The longitudinal cross-sectional shape of the guide groove on the bottom surface of the horizontal plate of the U-shaped plate 31 is convex, and the shape of the guide block 35 is convex, which matches the shape of the guide groove on the bottom surface of the horizontal plate of the U-shaped plate 31.

[0044] Since both the U-shaped plate 31 guide groove and the guide block 35 are convex, the guide block 35 will not detach when sliding in the guide groove, which further enhances the stability of the moving plate 34 and ensures the normal operation of the limiting mechanism 3.

[0045] It should be added that the motor 310 is electrically connected to the external PLC and the external power supply via wires, and the external PLC is also electrically connected to the external power supply via wires.

[0046] The motor 310 involved in this embodiment is existing technology, and its structure and working principle are as well known to those skilled in the art, and will not be described in detail here.

[0047] In this embodiment, during actual use, the external PLC controls the motor 310 to start and stop. The motor 310 drives the rotating column 32 to rotate the screw 33, causing the moving plate 34 to move back and forth along the guide groove of the U-shaped plate 31. The guide block 35 ensures smooth movement. The moving plate 34 drives the mounting plate 36 to move. The guide plate 38 and guide rod 39 assist the mounting plate 36 to move stably, so that the limiting rod 37 can be inserted into or disengaged from the limiting hole of the arc-shaped guide rail 2, thereby realizing the vertical limiting or release of the arc-shaped guide rail 2.

[0048] The arc-shaped guide rail 2 is slidably inserted into the slot of the base plate 1 via the insert block 21. The metal insert block 21 is attracted to the magnetic absorbing piece 11 to achieve horizontal limit. When maintenance is required, the PLC controls the motor 310 to retract the limit rod 37, so that the corresponding arc-shaped guide rail 2 can be removed separately. During installation, the insert block 21 is inserted into the slot and attracted, and the PLC controls the limit rod 37 to be inserted into the limit hole to complete the fixation. The convex groove of the arc-shaped guide rail 2 allows external components to slide stably along the S-shaped trajectory.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
