Technical Field

[0001] This utility model relates to the technical field of arc guide rail mechanisms, specifically a flip-up electric arc guide rail mechanism. Background Technology

[0002] The circular arc guide rail is a high-precision industrial device that achieves circular motion by rolling V-shaped rollers on the V-shaped guide rail surface. Its core structure is formed by modular combination of linear guide rails and circular arc guide rails to form a closed loop line, which has high rigidity, low friction characteristics and multi-station positioning capability.

[0003] The prior art discloses some invention patents in the field of circular arc guide rail mechanism processing technology. Among them, the invention patent with publication number CN119460591 A discloses a flip-up electric circular arc guide rail mechanism, characterized in that it includes: an active bearing group (1), a driven bearing group (2), an L-shaped adapter (3), a reducer (4), a handwheel (5), a locking mechanism (6), a mounting base plate (7), a circular arc guide rail (8), a slider trolley (9), a motor (10), and a pinion (11); the mounting base plate (7) is arc-shaped, its circular surface is perpendicular to the horizontal plane, and the outer side of the mounting base plate (7) is designed with gear teeth (71), that is, the gear teeth (71) are at the outermost edge of the circular surface of the mounting base plate (7); the present invention realizes the movement of the slider trolley in the circular arc trajectory controlled by the motor from vertical to horizontal at different flip angles, and provides a high-precision circular arc movement with position feedback function by using motor control and signal feedback technology.

[0004] However, the above method still has the following drawbacks in actual use: when the arc guide rail mechanism is flipping, it does not have an auxiliary structure, and the arc guide rail mechanism in operation is prone to shaking during the flipping process, which can easily lead to damage to the arc guide rail mechanism and reduce its flexibility. Utility Model Content

[0005] The purpose of this invention is to provide a reversible electric arc guide rail mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotatable electric arc guide rail mechanism, comprising a support frame, a rotating shaft rotatably connected inside the support frame, a motor fixedly connected to one side of the support frame, an arc guide rail body fixedly connected outside the rotating shaft, a sealing ring provided inside the arc guide rail body, a guide block provided inside the arc guide rail body, an auxiliary structure provided outside the rotating shaft, the auxiliary structure being connected to the lower part of the guide block, a snap-fit ​​structure provided inside the arc guide rail body, the snap-fit ​​structure being snap-fitted with the sealing ring, the auxiliary structure comprising a column, an auxiliary rod, and a limiting ring, a connecting plate rotatably connected outside the column, and a groove provided inside the connecting plate.

[0007] As a further preferred embodiment of this technical solution, one end of the motor is connected to the rotating shaft, the column is fixedly connected to the outside of the rotating shaft, and the auxiliary rod is fixedly connected to the bottom of the guide block.

[0008] As a further preferred embodiment of this technical solution, the auxiliary rod is slidably connected within the groove, the limiting ring is fixedly connected outside the auxiliary rod, and the limiting ring overlaps with the connecting plate.

[0009] As a further preferred embodiment of this technical solution, the guide block is provided with rollers, and the two sides of the guide block are fixedly connected with locking blocks, which are engaged in the sealing ring.

[0010] As a further preferred embodiment of this technical solution, the snap-fit ​​structure includes a guide rod, which is fixedly connected inside the guide block. A rotating plate is rotatably connected to the outside of the guide rod, and a mounting plate is fixedly connected to one side of the rotating plate.

[0011] As a further preferred embodiment of this technical solution, the mounting plate is engaged with the sealing ring, and bolts are provided inside the mounting plate, which is connected to the guide block by the bolts.

[0012] This utility model provides a reversible electric arc guide rail mechanism, which has the following advantages:

[0013] (1) By setting up an arc guide rail body, a guide block, a rotating shaft and a sealing ring, the arc guide rail mechanism is flipped when it is flipped. The arc guide rail body is driven by a motor to flip around the rotating shaft in the support frame. When the guide block runs on the surface of the arc guide rail body, the auxiliary rod under the guide block will slide in the groove. Then the auxiliary rod will drive the connecting plate to swing around the column. The column and the connecting plate will flip with the action of the rotating shaft. The arc guide rail mechanism can play a certain auxiliary role in the flipping of the arc guide rail body through the cooperation between the connecting plate, the groove and the limiting ring, so as to avoid the unstable phenomenon caused by the guide block in the arc guide rail body during operation, thereby ensuring the flexibility of the arc guide rail mechanism.

[0014] (2) By setting a sealing ring and a snap-fit ​​structure, the sealing ring is snapped into the body of the arc guide rail. The sealing ring will snap into the snap-fit ​​block. When the sealing ring is completely attached to the body of the arc guide rail, the mounting plate will rotate around the guide rod. After the rotation, the mounting plate will contact the sealing ring. Then the mounting plate will be threadedly connected to the guide block by bolts, so as to seal the guide rail area of ​​the arc guide rail body and prevent dust in the air from entering the body of the arc guide rail.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, a rotatable electric arc guide rail mechanism includes a support frame 1, a rotating shaft 2 rotatably connected inside the support frame 1, a motor 3 fixedly connected to one side of the support frame 1, an arc guide rail body 4 fixedly connected outside the rotating shaft 2, a sealing ring 6 provided inside the arc guide rail body 4, a guide block 5 provided inside the arc guide rail body 4, an auxiliary structure 7 provided outside the rotating shaft 2, the auxiliary structure 7 being connected to the lower part of the guide block 5, a snap-fit ​​structure 8 provided inside the arc guide rail body 4, the snap-fit ​​structure 8 being snap-fitted with the sealing ring 6, the auxiliary structure 7 including a column 701, an auxiliary rod 703 and a limiting ring 705, a connecting plate 702 rotatably connected outside the column 701, and a groove 704 provided inside the connecting plate 702.

[0022] like Figure 1 and Figure 3 As shown, one end of the motor 3 is connected to the rotating shaft 2, the column 701 is fixedly connected to the outside of the rotating shaft 2, the auxiliary rod 703 is fixedly connected to the bottom of the guide block 5, the auxiliary rod 703 is slidably connected in the groove 704, the limiting ring 705 is fixedly connected to the outside of the auxiliary rod 703, the limiting ring 705 overlaps with the connecting plate 702, the guide block 5 is provided with a roller 9, and the two sides of the guide block 5 are fixedly connected with a locking block 10, which is locked in the sealing ring 6;

[0023] By setting a limiting ring 705, which is installed on the outside of the auxiliary rod 703 and overlaps with the connecting plate 702, the limiting ring 705 is used to limit the sliding range of the auxiliary rod 703 in the groove 704, prevent the auxiliary rod 703 from disengaging from the groove 704 during sliding, and ensure that the linkage between the connecting plate 702 and the auxiliary rod 703 is always reliable. When the arc guide rail flips or the guide block 5 moves, the limiting ring 705 can buffer and absorb part of the impact force, reduce the vibration of the mechanism, and extend the service life.

[0024] like Figure 4 As shown, the snap-fit ​​structure 8 includes a guide rod 801, which is fixedly connected inside the guide block 5. A rotating plate 802 is rotatably connected to the outside of the guide rod 801. A mounting plate 803 is fixedly connected to one side of the rotating plate 802. The mounting plate 803 is snap-fitted with the sealing ring 6. A bolt 804 is provided inside the mounting plate 803. The mounting plate 803 is connected to the guide block 5 through the bolt 804.

[0025] By setting the locking block 10, which is fixed on both sides of the guide block 5 and engages with the sealing ring 6, the locking block 10 can effectively prevent dust and impurities from entering the guide rail, protect the guide rail and roller 9 system, and extend the service life. The locking block 10 provides a clear installation position to ensure that the sealing ring 6 is installed in place and avoids sealing failure due to misalignment.

[0026] This utility model provides a reversible electric circular arc guide rail mechanism, the specific working principle of which is as follows:

[0027] When the arc guide rail mechanism is in use, the sealing ring 6 can be snapped into the arc guide rail body 4, and the sealing ring 6 will be snapped into the locking block 10. When the sealing ring 6 is completely in contact with the arc guide rail body 4, it will cause the mounting plate 803 to rotate around the guide rod 801. After rotating, the mounting plate 803 will contact the sealing ring 6, and then the mounting plate 803 will be threadedly connected to the guide block 5 through the bolt 804.

[0028] When the arc guide rail mechanism is flipped, the motor 3 drives the arc guide rail body 4 to flip around the pivot 2 within the support frame 1. When the guide block 5 runs on the surface of the arc guide rail body 4, the auxiliary rod 703 below the guide block 5 slides in the groove 704. Then the auxiliary rod 703 drives the connecting plate 702 to swing around the column 701. The column 701 and the connecting plate 702 will flip with the action of the pivot 2.

[0029] 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.
