Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, and in particular to a cam transmission device. Background Technology

[0002] In the capacitor manufacturing process, many structures need to move up and down simultaneously to complete the corresponding production operations. However, currently, to enable these structures to move up and down simultaneously, they are basically driven by individual lifting mechanisms. But when multiple driving mechanisms drive simultaneously, there will inevitably be working errors, which will cause the corresponding production discontinuity, thus affecting the production continuity in the production process and consequently affecting production efficiency.

[0003] The technical problem to be solved by this application is: to design a cam transmission device that can ensure production continuity and thus improve production efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a cam transmission device that can ensure production continuity and thus improve production efficiency.

[0005] The technical solution adopted by this utility model is as follows: a cam transmission device, including a base plate, a rotating shaft rotatably connected thereto on the base plate, a cam mechanism connected thereto on the rotating shaft, and a linkage mechanism rotatably connected thereto on the base plate. The linkage mechanism is provided with an abutting block, which abuts against the cam mechanism to drive the linkage mechanism to move up and down.

[0006] In some embodiments, the substrate is provided with several mounting seats, and the rotating shaft is rotatably connected to the mounting seats.

[0007] In some embodiments, the rotating shaft includes a main drive shaft and a driven drive shaft, and a coupling is provided between the main drive shaft and the driven drive shaft for interconnection.

[0008] In some embodiments, the cam mechanism is located on the main drive shaft, and the cam mechanism includes a plurality of cams fixedly connected to the main drive shaft.

[0009] In some embodiments, a mounting frame is provided on the substrate, and a plurality of connecting frames are provided on the mounting frame. The linkage mechanism includes a plurality of links rotatably connected to the connecting frames, and each link corresponds to a cam.

[0010] In some embodiments, the linkage includes a first linkage and a second linkage fixedly connected to the first linkage for vertical lifting, the first linkage and the second linkage being arranged vertically between each other.

[0011] In some embodiments, the first link is rotatably connected to the connecting frame, the abutment block is provided on the first link, and the upper end of the second link is provided with a connector.

[0012] In some embodiments, the main drive shaft is provided with a transmission gear that is fixedly mounted thereto, and the transmission gear is used for transmission connection with an external motor.

[0013] In some embodiments, a gear set is provided on the drive shaft and fixedly mounted thereto.

[0014] This utility model has the following technical effects: By providing a cam mechanism on the rotating shaft and a linkage mechanism connected to it on the base plate, and the linkage mechanism is provided with an abutment block that abuts against the cam mechanism, when the rotating shaft rotates, it will drive the cam mechanism to rotate. When the cam mechanism rotates, it will drive the abutment block to move up and down with the contour of the cam, thereby driving the linkage mechanism to move up and down synchronously. Since the cam mechanism is entirely mounted on the rotating shaft, the cam mechanism drives the linkage mechanism to move up and down simultaneously and continuously through the abutment block, thus ensuring production continuity and improving production efficiency.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This utility model provides a technical solution: a cam transmission device, including a base plate 1, a rotating shaft 2 rotatably connected to the base plate 1, a cam mechanism 3 connected to the rotating shaft 2, and several mounting seats 10 on the base plate 1. The rotating shaft 2 is rotatably connected to the mounting seats 10. The rotating shaft 2 includes a main drive shaft 20 and a driven drive shaft 21, and a coupling 22 is provided between the main drive shaft 20 and the driven drive shaft 21 to connect them, so that the main drive shaft 20 and the driven drive shaft 21 can rotate synchronously. The cam mechanism 3 is located on the main drive shaft 20, and the cam mechanism 3 includes several cams 30 fixedly connected to the main drive shaft 20. A linkage mechanism 4 rotatably connected to the base plate 1 is also provided, and the linkage mechanism 4 is provided with an abutment block 5. The abutment block 5 abuts against the cam mechanism 3 to drive the linkage mechanism 4 to move up and down. A mounting seat 10 is provided on the base plate 1. The mounting frame 11 has several connecting frames 12. The linkage mechanism 4 includes several connecting rods 40 rotatably connected to the connecting frames 12, and each connecting rod 40 corresponds to a cam 30. Therefore, when the rotating shaft 2 rotates, it will drive the cam 30 located on the main drive shaft 20 to rotate synchronously. Since the abutment block 5 on the linkage mechanism 4 abuts against the surface of the cam 30, the abutment block 5 will move up and down with the surface contour of the cam 30 when the cam 30 rotates, thereby driving the connecting rod 40 connected to the abutment block 5 to move up and down synchronously. Since the upper end of the connecting rod 40 is used to connect various production structures, it needs to be driven by the lifting and lowering of the connecting rod 40. Since the cam mechanism 3 is entirely mounted on the rotating shaft 2, the lifting and lowering of the cam mechanism 3 through the abutment block 5 is all carried out simultaneously and continuously. Therefore, it can be ensured that the lifting and lowering actions of the linkage mechanism 4 are all carried out synchronously, thereby ensuring the continuity of the entire production and improving production efficiency.

[0021] The connecting rod 40 includes a first connecting rod 41 and a second connecting rod 42 fixedly connected to the first connecting rod 41 for vertical lifting. The first connecting rod 41 and the second connecting rod 42 are vertically arranged. The first connecting rod 41 is rotatably connected to the connecting frame 12. The abutment block 5 is provided on the first connecting rod 41. When the cam 30 rotates, the abutment block 5 can move up and down according to the contour of the cam 30 surface, thereby driving the first connecting rod 41 to move up and down. Since the second connecting rod 42 is vertically arranged at one end of the first connecting rod 41, the second connecting rod 42 is equivalent to moving up and down while the first connecting rod 41 moves up and down, thereby driving the structure connected above the second connecting rod 42 to move up and down. In order to enable the upper end of the second connecting rod 42 to be connected to other production structures, a connector 43 is also provided at the upper end of the second connecting rod 42. The connector 43 is used to connect the second connecting rod 42 to other production structures.

[0022] The main drive shaft 20 is also equipped with a transmission gear 24 that is fixedly installed thereto. The transmission gear 24 is connected to an external motor via a transmission belt. The main drive shaft 20 is rotated by the motor driving the transmission gear 24.

[0023] A gear set 25 is also provided on the drive shaft 21 and fixedly installed therewith. The gear set 25 can also drive other production structures by connecting to the drive belt, and can also provide driving force synchronized with the linkage mechanism 4.

[0024] The working principle of this utility model is as follows: A cam mechanism 3 is provided on the rotating shaft 2, and a linkage mechanism 4 connected to it is provided on the base plate 1. The linkage mechanism 4 is provided with an abutting block 5, which abuts against the cam mechanism 3. Therefore, when the rotating shaft 2 rotates, it will drive the cam mechanism 3 to rotate. When the cam mechanism 3 rotates, it will drive the abutting block 5 to move up and down with the contour of the cam 30, thereby driving the linkage mechanism 4 to move up and down synchronously. Since the cam mechanism 3 is entirely installed on the rotating shaft 2, the cam mechanism 3 drives the linkage mechanism 4 to move up and down simultaneously and continuously through the abutting block 5. Therefore, it can ensure production continuity and improve production efficiency.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
