Description

Technical Field

[0001] This utility model belongs to the field of linkage shaft technology, and in particular relates to a high-precision synchronous linkage shaft. Background Technology

[0002] Many transportation platforms need to achieve synchronous transportation. While achieving synchronization on a row of transportation tracks is relatively easy, disconnecting the synchronous drive under synchronous driving conditions is relatively difficult. Furthermore, if the drive of a certain transportation track is disconnected independently, the remaining transportation tracks still need to maintain synchronous linkage, which makes this requirement even more challenging to meet. Utility Model Content

[0003] The purpose of this invention is to provide a high-precision synchronous linkage shaft, which realizes the synchronous driving of two synchronous drive bevel gear mechanisms through a coupling mechanism. The synchronous mechanism can realize the synchronous linkage between a row of linkage gear mechanisms, solving the problems of the existing difficulty in disconnecting the synchronous drive and the difficulty in achieving synchronous linkage of other transport tracks even when the drive of a certain transport track is independently disconnected.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a high-precision synchronous linkage shaft, comprising a coupling mechanism, a synchronization mechanism, a synchronization lead screw mechanism, and a synchronization drive bevel gear mechanism. Two of the synchronization drive bevel gear mechanisms are symmetrically arranged to form a set of linkage gear mechanisms. The two synchronization drive bevel gear mechanisms within the set of linkage gear mechanisms are connected or disconnected by the coupling mechanism. A row of linkage gear mechanisms is arranged, and adjacent linkage gear mechanisms are connected or disconnected by the synchronization mechanism. The synchronization lead screw mechanism includes a displacement base plate, two synchronization lead screws, and a synchronization gear disk. The synchronization lead screws are fitted with the synchronization gear disk at the same end position in the same direction. The synchronization lead screws are mounted with mounting posts near both ends. The four mounting posts are respectively fixed at the four corner positions of the displacement base plate. The coupling mechanism, synchronization mechanism, synchronization lead screw mechanism, and synchronization drive bevel gear mechanism are mounted on a base plate.

[0005] The present invention is further configured such that the synchronous drive bevel gear mechanism includes an L-shaped bracket, a rotating shaft cylinder and a first bevel gear disk, one end of the rotating shaft cylinder is connected through the axis of the first bevel gear disk, the L-shaped bracket has two bearings embedded in its end position and the other end of the rotating shaft cylinder passes through and is fixed on the two bearings, the synchronous gear disk is a second bevel gear disk, and the first bevel gear disk 5 will mesh with the corresponding second bevel gear disk at a 90° angle.

[0006] The present invention is further configured such that the inner wall of the rotating shaft cylinder is a regular octagonal hollow hole.

[0007] The present invention is further configured such that the coupling mechanism includes a coupling rod, a push plate, and an inverted U-shaped frame. One end of the coupling rod is connected to a long regular octagonal rod, and the other end is connected to a short regular octagonal rod. One end of the push plate has a bearing embedded in it and the bearing is sleeved in the middle position of the coupling rod. The other end of the push plate is movably sleeved on the middle crossbar of the inverted U-shaped frame. Two cylinders are symmetrically arranged on both sides of one end of the crossbar of the inverted U-shaped frame. The telescopic shaft of the cylinder is fixed on the push plate. Both the long and short regular octagonal rods can be matched and inserted into the hollow hole of the regular octagon.

[0008] The present invention is further configured such that the coupling mechanism and the synchronization mechanism have the same structure, the shaft in the synchronization mechanism is a synchronization coupling rod, and the lengths of the synchronization coupling rod and the coupling rod are different in the middle section.

[0009] The present invention is further configured such that a lateral displacement component is installed at the bottom of the displacement base plate, and the lateral displacement component enables the displacement base plate to move laterally.

[0010] This utility model has the following beneficial effects: 1. The present invention relates to two synchronous drive bevel gear mechanisms for driving two synchronous lead screws in a synchronous lead screw mechanism to rotate synchronously. The two synchronous drive bevel gear mechanisms are connected by a coupling mechanism. The coupling rod connects the two rotating cylinders to achieve synchronous rotation of the two rotating cylinders. The linkage between adjacent linkage gear mechanisms is achieved through the synchronization mechanism. The linkage drive of the linkage gear mechanism can be disconnected in real time, and the drive between the two synchronous drive bevel gear mechanisms can also be disconnected.

[0011] 2. This utility model achieves linkage drive by displacing the displacement base plate, causing the synchronous gear disk to disengage from the corresponding first conical gear disk, thereby enabling other synchronous screw mechanisms to still achieve linkage drive even when one synchronous screw mechanism is disconnected from the drive.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model is a high-precision synchronous linkage shaft, including a coupling mechanism 6, a synchronization mechanism 7, a synchronization screw mechanism, and a synchronization drive bevel gear mechanism. Two of the synchronization drive bevel gear mechanisms are symmetrically arranged to form a set of linkage gear mechanisms. The two synchronization drive bevel gear mechanisms in the set of linkage gear mechanisms are connected or disconnected by the coupling mechanism 6. A row of linkage gear mechanisms is arranged, and adjacent linkage gear mechanisms are connected or disconnected by the synchronization mechanism 7. The synchronization screw mechanism includes a displacement base plate 2, two synchronization screws 3, and a synchronization gear disk 4. The synchronization screws 3 are fitted with the synchronization gear disk 4 at the same end position in the same direction. The synchronization screws 3 are fitted with mounting posts near the two ends. The four mounting posts are respectively fixed at the four corner positions of the displacement base plate 2. The coupling mechanism 6, the synchronization mechanism 7, the synchronization screw mechanism, and the synchronization drive bevel gear mechanism are mounted on the base plate 1.

[0021] The drive structure (motor and connecting shaft, the motor shaft is connected to the synchronous drive bevel gear mechanism through the connecting rod) is installed on the outermost synchronous drive bevel gear mechanism. When it is necessary to connect two synchronous drive bevel gear mechanisms, the connecting rod mechanism 6 needs to dock the two synchronous drive bevel gear mechanisms to complete the synchronization. When it is necessary to achieve synchronous linkage between multiple linkage gear mechanisms, the synchronization mechanism 7 is used to dock them to achieve linkage.

[0022] The synchronous drive bevel gear mechanism includes an L-shaped bracket 50, a rotating shaft cylinder 51, and a first bevel gear disk 5. One end of the rotating shaft cylinder 51 is connected through the axis of the first bevel gear disk 5. The L-shaped bracket 50 has two bearings embedded in its end position, and the other end of the rotating shaft cylinder 51 passes through and is fixed on the two bearings. The synchronous gear disk 4 is a second bevel gear disk, and the first bevel gear disk 5 will mesh with the corresponding second bevel gear disk at a 90° angle.

[0023] When the rotating cylinder 51 rotates, the first conical gear disk 5 will rotate, and the L-shaped bracket 50 fixes the rotating cylinder 51 through two bearings, but can also ensure that the rotating cylinder 51 rotates. The first conical gear disk 5 drives the second conical gear disk to rotate to realize the rotation of the synchronous lead screw 3.

[0024] The inner wall of the rotating shaft cylinder 51 is a regular octagonal hollow hole 511. The regular octagonal hollow hole 511 ensures that the hollow structure is not a circular hole, thus preventing the connecting rod from rotating inside.

[0025] The coupling mechanism 6 includes a coupling rod 61, a push plate 62, and an inverted U-shaped frame 63. One end of the coupling rod 61 is connected to a long regular octagonal rod 611, and the other end is connected to a short regular octagonal rod 612. One end of the push plate 62 has a bearing embedded in it and the bearing is sleeved in the middle position of the coupling rod 61. The other end of the push plate 62 is movably sleeved on the middle crossbar of the inverted U-shaped frame 63. Two cylinders 64 are symmetrically arranged on both sides of one end of the crossbar of the inverted U-shaped frame 63. The telescopic shafts of the cylinders 64 are fixed on the push plate 62. The long regular octagonal rod 611 and the short regular octagonal rod 612 can be matched and inserted into the regular octagonal hollow hole 511.

[0026] The long regular octagonal rod 611 and the short regular octagonal rod 612 have the same thickness. The use of a regular octagonal shape makes the rod diameter larger than a regular square rod, but this does not affect the rotation drive. In use, the long regular octagonal rod 611 is first fully inserted into a rotating shaft cylinder 51. When docking is required, the short regular octagonal rod 612 is inserted into the corresponding rotating shaft cylinder 51, while the long regular octagonal rod 611 is only pulled out half its length from the interior of the rotating shaft cylinder 51. The connecting rod 61 is moved at a fixed distance by the push plate 62.

[0027] The coupling mechanism 6 and the synchronization mechanism 7 have the same structure. The shaft in the synchronization mechanism 7 is a synchronization coupling rod 71. The length of the synchronization coupling rod 71 and the coupling rod 61 in the middle section are different.

[0028] The coupling mechanism 6 and the synchronization mechanism 7 have the same structure and principle. However, when the distance between adjacent linkage gear mechanisms is set as needed, the length of the synchronization coupling rod 71 is set according to the distance.

[0029] A lateral displacement assembly is installed at the bottom of the displacement base plate 2, which enables the displacement base plate 2 to move laterally. The lateral displacement assembly can be driven by a lead screw and a servo motor to move the displacement base plate 2, and the displacement base plate can be limited by a limiting structure. The specific displacement is designed according to needs.
