Technical Field

[0001] The present invention relates to the technical field of elevators for machining, and particularly to an elevator for mechanical design, manufacturing and automated machining. Background Art

[0002] With the rapid development of mechanical design, manufacturing and automation technology, industrial production has put forward higher requirements for the efficiency, precision and automation level of equipment. In the processes of machining, assembly, logistics, etc., the vertical handling of materials or workpieces is one of the core operations. Traditional manual handling or simple lifting equipment has been difficult to meet the requirements of high precision, high efficiency and high safety in modern manufacturing. As a key equipment for vertical transportation, the technological upgrade of elevators has become an inevitable trend in the industry development.

[0003] In the prior art, when using an elevator to transport mechanical parts, due to different lifting speeds and the weights of mechanical parts, vibrations of different degrees will be generated during the lifting process. Some mechanical parts have fine structures and are prone to damage when subjected to vibrations, affecting subsequent processing operations. Therefore, an elevator for mechanical design, manufacturing and automated machining is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the prior art that when using an elevator to transport mechanical parts, due to different lifting speeds and the weights of mechanical parts, vibrations of different degrees will be generated during the lifting process, and some mechanical parts have fine structures and are prone to damage when subjected to vibrations, affecting subsequent processing operations, and to propose an elevator for mechanical design, manufacturing and automated machining.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A lift for mechanical design, manufacturing and automated processing, comprising a base, a lifting platform is arranged above the base, a chassis is fixedly connected to the lifting platform below, a vibration reduction mechanism is arranged inside the chassis, the vibration reduction mechanism comprises a first motor arranged inside the chassis, a driving rod is arranged at the output end of the first motor, a first gear is fixedly connected to the side of the driving rod away from the first motor, a first rack plate is meshedly connected to the side of the first gear, a moving plate is transmission-connected to the side of the first rack plate away from the first gear, a spring is fixedly connected to the side of the moving plate, an elastic damping plate is fixedly connected to the side of the spring away from the moving plate, the first gear is away from the first rack plate A second rack plate is meshed and connected on one side, and the same movable plate, spring and elastic damping plate are arranged on the side of the second rack plate away from the first gear. After the first motor is started, the first gear is controlled to rotate by the driving rod, and the first gear drives the first rack plate and the second rack plate to move in opposite directions. The first rack plate drives the spring and the elastic damping plate to move through the movable plate, and the elastic damping plate moves to fit the mechanical parts and the spring is gradually compressed to generate elastic potential energy. The second rack plate drives another group of movable plates, springs and elastic damping plates to move in the same way. The two groups of springs move toward each other and generate relative elastic potential energy prestress according to the vibration size.

[0007] Wherein, multiple groups of springs are arranged between the two groups of moving plates and the elastic damping plate so that the springs are subjected to uniform force.

[0008] The above technical solution further includes:

[0009] The chassis is fixedly connected to the first motor, a connecting rod is fixedly connected to the side of the first rack plate away from the first gear, and the upper part of the connecting rod is fixedly connected to the moving plate.

[0010] A telescopic rod is fixedly connected to one side of the movable plate close to the spring, and the telescopic rod is fixedly connected to the elastic damping plate.

[0011] Wherein, a telescopic rod is fixedly connected between the elastic damping plate and the movable plate. When the spring is extended or retracted, the telescopic rod is driven to extend or retract, thereby preventing the spring from being overly compressed.

[0012] A square groove is provided on one side of the lifting platform close to the connecting rod.

[0013] A support rod is fixedly connected to the lower side of the first rack plate, a slot plate is slidably connected to the side of the support rod away from the first rack plate, and the slot plate is fixedly connected to the chassis.

[0016] On the side of the lifting table, a hydraulic rod is fixedly connected. The output end of the hydraulic rod is provided with a push plate.

[0017] On the side of the push plate, a single-end rack plate is fixedly connected. Below one side of the single-end rack plate away from the push plate, a second gear is meshed and connected.

[0018] On the side of the second gear close to the lifting table, a rotating shaft is fixedly connected. The rotating shaft is rotatably connected to the lifting table, and a baffle is fixedly connected above the rotating shaft.

[0019] The present invention has the following beneficial effects:

[0020] 1. In the present invention, through the opposite movement of the two groups of elastic damping plates and springs, the elastic potential energy prestress on both sides of the mechanical parts is used to offset the vibration, significantly reducing the vibration generated during the lifting process due to speed and weight differences, effectively protecting the fine mechanical parts from damage, ensuring the subsequent processing accuracy. The elastic potential energy of the spring can be dynamically adjusted according to the vibration magnitude, realizing the precise suppression of vibration under different working conditions, improving the adaptability of the equipment to complex transportation environments, and reducing the risk of part damage caused by vibration.

[0021] 2. In the present invention, the linkage design of the hydraulic rod, the push plate, the single-end rack plate and the second gear realizes the automatic pushing of the mechanical parts and the opening of the baffle, eliminating the need for manual intervention, and improving the automation degree and operation efficiency of the production line.

[0022] 3. In the present invention, the independent design of the vibration damping mechanism and the lifting and pushing systems facilitates modular combination and expansion according to different processing requirements, reduces the equipment upgrade cost, and improves the flexibility and maintainability of the overall system.

Above the base 1, there is a lifting platform 2. Below the lifting platform 2, there is a fixed connection with a machine case 3. Inside the machine case 3, there is a vibration damping mechanism. The vibration damping mechanism includes a first motor 4 arranged inside the machine case 3. The output end of the first motor 4 is provided with a driving rod 5. On the side of the driving rod 5 away from the first motor 4, there is a fixed connection with a first gear 6. On the side of the first gear 6, there is an engaged connection with a first rack plate 7. On the side of the first rack plate 7 away from the first gear 6, there is a transmission connection with a moving plate 9. On the side of the moving plate 9, there is a fixed connection with a spring 10. On the side of the spring 10 away from the moving plate 9, there is a fixed connection with an elastic damping plate 11. On the side of the first gear 6 away from the first rack plate 7, there is an engaged connection with a second rack plate 14. On the side of the second rack plate 14 away from the first gear 6, there are the same moving plate 9, spring 10 and elastic damping plate 11. After the first motor 4 is started, it controls the first gear 6 to rotate through the driving rod 5. The first gear 6 drives the first rack plate 7 and the second rack plate 14 to move in opposite directions. The first rack plate 7 drives the spring 10 and the elastic damping plate 11 to move through the moving plate 9. The elastic damping plate 11 moves to fit the mechanical part and the spring 10 will gradually compress to generate elastic potential energy. The second rack plate 14 drives another set of moving plate 9, spring 10 and elastic damping plate 11 to move in the same way. The two springs 10 move towards each other and generate relative elastic potential energy prestress according to the vibration magnitude.

[0034] There is a fixed connection between the machine case 3 and the first motor 4. On the side of the first rack plate 7 away from the first gear 6, there is a fixed connection with a connecting rod 8. Above the connecting rod 8, there is a fixed connection with the moving plate 9.

[0036] On the side of the lifting platform 2 close to the connecting rod 8, there is a square groove 13.

[0037] Above the base 1, there is a fixed connection with a lifting frame 17. Below the base 1, there is a fixed connection with a second motor 18. The output end of the second motor 18 is provided with a threaded rod 19. On the side of the threaded rod 19 close to the lifting platform 2, there is a threaded connection with a base plate 20.

[0038] There is a sliding connection between the lifting frame 17 and the lifting platform 2. There is a fixed connection between the base plate 20 and the lifting platform 2. There is a sliding connection between the base plate 20 and the lifting frame 17.

[0039] In this embodiment, a lifting platform 2 is arranged above the base 1. The vibration damping mechanism arranged inside the chassis 3 fixedly connected below the lifting platform 2 is started, and the first motor 4 in the vibration damping mechanism starts to operate. The first motor 4 is fixedly installed on the inner wall of the chassis 3. When the first motor 4 operates, it starts to control the driving rod 5 arranged at its output end to rotate. When the driving rod 5 rotates, it drives the first gear 6 fixedly connected to the other side of the driving rod 5 to rotate. When the first gear 6 rotates, it drives the first rack plate 7 meshed and connected to its side to move. And the other side of the first gear 6 will drive the second rack plate 14 to move in the opposite direction to the first rack plate 7. When the first rack plate 7 moves, it drives the connecting rod 8 above the other side of the first rack plate 7 to move. The connecting rod 8 will move on the inner wall of the square groove 13 opened inside the lifting platform 2. When the connecting rod 8 moves, it drives the moving plate 9 fixedly connected to the other end of the connecting rod 8 to move. A spring 10 is fixedly connected to the side of the moving plate 9. There are multiple groups of springs 10. The moving plate 9 will drive multiple groups of springs 10 to move. Multiple groups of springs 10 will drive the elastic damping plate 11 fixedly connected to the other side of the springs 10 to move. The second rack plate 14 drives the same moving plate 9, springs 10 and elastic damping plate 11 to move according to the same principle, so that the two elastic damping plates 11 move towards each other and fit and fix the mechanical parts, and will compress multiple groups of springs 10 and make them generate elastic potential energy. According to the magnitude of the vibration generated during the lifting of the device, the magnitude of the elastic potential energy is controlled, and the prestress of the elastic potential energy generated on both sides of the mechanical parts is used to offset the vibration force, achieving efficient vibration damping during the lifting process.

[0040] A lifting frame 17 is fixedly connected above the base 1. The second motor 18 fixedly installed below the base 1 is started, so that when the second motor 18 operates, it starts to control the threaded rod 19 arranged at its output end to rotate. The threaded rod 19 rotates in the groove opened inside the lifting frame 17. A substrate 20 is threadedly connected to the side of the threaded rod 19 away from the second motor 18. The substrate 20 is slidably connected to the lifting frame 17, so that the threaded rod 19 rotates inside the substrate 20 and generates spiral power, and the substrate 20 starts to move up and down inside the lifting frame 17. When the substrate 20 moves up and down, it drives the lifting platform 2 fixedly connected to the side of the substrate 20 to lift. And the lifting platform 2 is slidably connected to the lifting frame 17 to ensure its stability during lifting, and the lifting operation of mechanical design and manufacturing and its automation processing is completed.

[0041] Embodiment 2

[0042] As Figures 1 - 7 shown, based on Embodiment 1, a support rod 15 is fixedly connected below the first rack plate 7. A groove plate 16 is slidably connected to the side of the support rod 15 away from the first rack plate 7. The groove plate 16 is fixedly connected to the chassis 3.

[0043] A hydraulic rod 21 is fixedly connected to the side of the lifting platform 2, and a push plate 22 is arranged at the output end of the hydraulic rod 21.

[0044] A single-end rack plate 23 is fixedly connected to the side of the push plate 22, and a second gear 24 is meshed and connected below the side of the single-end rack plate 23 away from the push plate 22.

[0045] A rotating shaft 25 is fixedly connected to the side of the second gear 24 close to the lifting platform 2. The rotating shaft 25 is rotatably connected to the lifting platform 2, and a baffle 26 is fixedly connected above the rotating shaft 25.

[0046] In this embodiment, when the first rack plate 7 moves, the first rack plate 7 will drive the support rod 15 fixedly connected to its lower part to move. When the support rod 15 moves, it will slide inside the groove plate 16 slidably connected to the other side of the support rod 15, and the groove plate 16 is fixedly connected to the chassis 3. The same support rod 15 and groove plate 16 are arranged below the second rack plate 14 to ensure the stability of the movement of the first rack plate 7 and the second rack plate 14. When the lifting platform 2 rises to a certain position, the hydraulic rod 21 fixedly connected to the side of the lifting platform 2 is started. When the hydraulic rod 21 operates, it starts to control the push plate 22 arranged at its output end to move. The push plate 22 pushes the mechanical parts above the lifting platform 2, and when the push plate 22 moves, it will drive the single-end rack plate 23 fixedly connected to its side to move. The structure with a rack part at the other end of the single-end rack plate 23 is meshed and connected with the second gear 24. When the single-end rack plate 23 moves, it drives the second gear 24 to rotate. After the second gear 24 rotates 90 degrees, it disengages from the meshing with the single-end rack plate 23. When the second gear 24 rotates, it will drive the rotating shaft 25 to rotate. The rotating shaft 25 rotates inside the lifting platform 2 and drives the baffle 26 arranged above it to rotate 90 degrees, so that the baffle 26 no longer blocks the mechanical parts, and at the same time, the push plate 22 will push the mechanical parts out of the device through the baffle 26 for subsequent processing.
