Description

Technical Field

[0001] This utility model relates to the technical field of aluminum electrolytic capacitor assembly machines, specifically a lifting device for an aluminum electrolytic capacitor assembly machine. Background Technology

[0002] Aluminum electrolytic capacitors are used in electrical equipment such as mobile phones, computers, cameras, industrial automation equipment, and switching power supplies to change power filtering and energy storage, as well as to ensure the stability and reliability of power output. Assembly machines are production equipment for aluminum electrolytic capacitors. Due to their large size, it is difficult to adjust the assembly machine to a certain height during operation. In order to facilitate use, a lifting device is required to adjust the height of the assembly machine.

[0003] Currently, the lifting devices of assembly machines mainly achieve lifting by rotating and extending between the threaded sleeve and the threaded rod. For example, a patent with publication number CN213691793U discloses a lifting device for an aluminum electrolytic capacitor assembly machine. It uses the interaction of the first and second bevel gears and the interaction of the first and second pulleys to enable the two threaded rods to rotate up and down, thereby realizing the height adjustment of the assembly machine body. However, the existing lifting devices for assembly machines have a large overall structure and occupy a lot of space, and cannot be folded or stored, making them inconvenient to store when not in use. Therefore, a lifting device for an aluminum electrolytic capacitor assembly machine is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, and addressing the problems of large overall size and inability to be folded, which makes storage inconvenient, this utility model proposes a lifting device for an aluminum electrolytic capacitor assembly machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a lifting device for an aluminum electrolytic capacitor assembly machine, comprising a bearing plate; a rotation limiting component is installed under each of the two opposite sides of the bearing plate, and an expansion component is installed under each of the rotation limiting components;

[0006] A spline shaft is provided between the drive ends of the two expansion components;

[0007] The drive end of the expansion assembly is rotatably mounted with an inner spline sleeve, a worm gear is fixedly connected to the inner spline sleeve, and the spline shaft passes through the inner spline sleeves of both expansion assemblies.

[0008] The main body of the assembly machine is fixed on the support plate.

[0009] Preferably, the rotation limiting assembly includes a hollow shaft fixed to the side of the bearing plate, a rotating shaft rotatably installed inside the hollow shaft, a U-shaped frame provided below the hollow shaft, and the two ends of the rotating shaft respectively fixed to the inner wall of the U-shaped opening of the U-shaped frame. The rotating shaft is provided with a first pin hole and a second pin hole, and the center line of the second pin hole is perpendicular to the center line of the first pin hole.

[0010] Preferably, a fixed sleeve is fixedly connected to the outer wall of the rotating shaft, a limiting ring is fixedly connected to the port of the fixed sleeve, a pin is slidably arranged inside the limiting ring, a baffle is fixedly connected to the pin and the baffle is located inside the fixed sleeve, and a spring is sleeved on the pin and the spring is located between the limiting ring and the baffle.

[0011] Preferably, the end of the pin located inside the fixed sleeve can be extended into the second pin hole and the second pin hole respectively, and the end of the pin located outside the fixed sleeve is fixedly connected to the first limiting plate.

[0012] Preferably, the expansion assembly is internally threaded with a bidirectional screw, a bushing is rotatably mounted at the end of the bidirectional screw, a bracket is fixedly connected to the outer wall of the bushing, and the inner spline sleeve is rotatably mounted on the bracket. One end of the bidirectional screw is fixedly connected to a worm gear, and the worm gear is meshed and driven on the worm gear. The other end of the bidirectional screw is fixedly connected to a second limiting plate.

[0013] Preferably, the expansion assembly includes an adapter fixed to the U-shaped frame, with a first support rod rotatably mounted on each of the two side walls of the adapter, a second support rod rotatably connected to the end of each first support rod, and threaded sleeves fixed to the rotatable connecting shafts of the first and second support rods on both sides, with a bidirectional screw threaded between the two threaded sleeves, and a support seat rotatably connected to the bottom ends of the second support rods on both sides.

[0014] Preferably, one end of the splined shaft is fixedly connected to a rotating disk, and the other end of the splined shaft is threadedly connected to a nut.

[0015] The advantages of this utility model are:

[0016] This utility model adjusts the support height of the bearing plate by increasing the distance between the two side adapters and the support base. When the first limiting plate is pulled, it will drive the pin to extend out of the fixed sleeve, thereby releasing the rotation restriction on the rotating shaft. This allows the expansion components on both sides to flip inward and fit against the bottom of the bearing plate at the same time. Under the action of the spring, the end of the pin will extend and fit into the first pin hole to fix the expansion components that fit against the bottom of the bearing plate, thereby reducing the space occupied by the device.

[0029] 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 scope of protection of the present utility model.

[0030] For examples, please refer to Figure 1-6 As shown, a lifting device for an aluminum electrolytic capacitor assembly erector includes a support plate 1; a rotation limiting component 2 is installed under each of the two opposite sides of the support plate 1, and an expansion component 3 is installed under each of the rotation limiting components 2.

[0031] A spline shaft 4 is provided between the driving ends of the two expansion components 3;

[0032] The drive end of the expansion component 3 is rotatably mounted with an inner spline sleeve 310, and a worm gear 311 is fixedly connected to the inner spline sleeve 310. The spline shaft 4 is simultaneously disposed inside the inner spline sleeves 310 in both expansion components 3.

[0033] The main body 5 of the assembly machine is fixed on the support plate 1.

[0034] The rotation limiting assembly 2 includes a hollow shaft 21 fixed to the side of the bearing plate 1. A rotating shaft 22 is rotatably installed inside the hollow shaft 21. A U-shaped frame 23 is provided below the hollow shaft 21, and the two ends of the rotating shaft 22 are respectively fixed to the inner wall of the U-shaped opening of the U-shaped frame 23. A first pin hole 24 and a second pin hole 25 are provided on the rotating shaft 22, and the center line of the second pin hole 25 is perpendicular to the center line of the first pin hole 24.

[0035] A fixed sleeve 26 is fixedly connected to the outer wall of the rotating shaft 22. A limiting ring 27 is fixedly connected inside the port of the fixed sleeve 26. A pin 28 is slidably arranged inside the limiting ring 27. A baffle 29 is fixedly connected to the pin 28 and is located inside the fixed sleeve 26. A spring 210 is sleeved on the pin 28 and is located between the limiting ring 27 and the baffle 29.

[0036] The end of the pin 28 located inside the fixed sleeve 26 can be extended into the second pin hole 25 and the second pin hole 25 respectively. The end of the pin 28 located outside the fixed sleeve 26 is fixedly connected to the first limiting plate 211.

[0037] The expansion assembly 3 is internally threaded with a bidirectional screw 35. A bushing 38 is rotatably mounted on the end of the bidirectional screw 35. A bracket 39 is fixedly connected to the outer wall of the bushing 38, and the inner spline sleeve 310 is rotatably mounted on the bracket 39. One end of the bidirectional screw 35 is fixedly connected to a worm gear 312, and the worm 311 is meshed and driven by the worm gear 312. The other end of the bidirectional screw 35 is fixedly connected to a second limiting plate 37.

[0038] The expansion assembly 3 includes an adapter seat 31 fixed under the U-shaped frame 23. A first support rod 32 is rotatably installed on both side walls of the adapter seat 31. A second support rod 33 is rotatably connected to the end of each first support rod 32. Threaded sleeves 34 are fixedly connected to the rotatable connecting shafts of the first support rod 32 and the second support rod 33 on both sides. A bidirectional screw 35 is threaded between the two threaded sleeves 34. A support seat 36 is rotatably connected to the bottom end of the second support rods 33 on both sides.

[0039] One end of the spline shaft 4 is fixedly connected to a rotating disk 41, and the other end of the spline shaft 4 is threadedly connected to a nut 42.

[0040] During operation, the existing assembly machine lifting device has a large overall structure and occupies a lot of space, and cannot be folded and stored, making it inconvenient to store when idle. In this solution, in the initial state, the spring 210 will always push the baffle 29 to the side opposite to the limiting ring 27, so as to drive the pin 28 to retract into the fixed sleeve 26 and extend the end of the pin 28 into the second pin hole 25 or the first pin hole 24.

[0041] Before operation, the end of the pin 28 is engaged in the second pin hole 25. By rotating the rotating disk 41, the rotating disk 41 simultaneously drives the inner spline sleeves 310 in the two expansion components 3 to rotate. The rotation of the inner spline sleeves 310 drives the worm 311 to rotate. Under the transmission meshing action of the worm 311 and the worm wheel 312, the rotation of the worm 311 drives the double-headed screw 35 through the worm wheel 312 to rotate. The rotation of the double-headed screw 35 drives the two threads threaded on it to rotate. The sleeve 34 moves, which in turn causes the rotational connection between the first support rod 32 and the second support rod 33 on both sides to gradually decrease, so as to gradually increase the included angle between the first support rod 32 and the second support rod 33. After the included angle between the first support rod 32 and the second support rod 33 increases, the distance between the adapter seat 31 and the support seat 36 will also increase. In this way, the support height of the bearing plate 1 is adjusted by increasing the distance between the adapter seat 31 and the support seat 36 on both sides, thereby adjusting the support height of the main body 5 of the assembly machine.

[0042] When the device is not in use and needs to be stored, first rotate the spline shaft 4 in the reverse direction to gradually reduce the included angle between the rotating rods of the first support rod 32 and the second support rod 33, thereby reducing the distance between the adapter 31 and the support seat 36, and thus lowering the support height of the bearing plate 1. Then, unscrew the nut 42 from the end of the spline shaft 4 and pull the spline shaft 4 out from the inner spline sleeve 310 in the two expansion components 3. Pull the first limiting plate 211. When the first limiting plate 211 is pulled, it will cause the pin 28 to extend out from the fixed sleeve 26. When the pin 28 extends, it will squeeze the spring 210 towards the limiting ring 27, causing it to contract. When the device contracts, the end of the pin 28 will move out of the second pin hole 25, thereby releasing the rotation restriction on the rotating shaft 22. At this time, the rotating shaft 22 can be rotated, so that the expansion components 3 on both sides rotate around the rotating shaft 22 in the rotation limit component 2 connected to them, and the expansion components 3 on both sides flip inward and fit against the bottom of the support plate 1. At this time, the first pin hole 24 will be directly opposite the fixing sleeve 26, and under the action of the spring 210, the end of the pin 28 will extend and fit into the first pin hole 24 to restrict the rotation of the rotating shaft 22 again, so as to fix the expansion component 3 that fits against the bottom of the support plate 1, thereby reducing the space occupied by the device.

[0043] It achieves the effect of easy folding and storage, and occupies less space compared to traditional lifting devices, thus reducing space occupancy.

[0044] 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 illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
