Description

Technical Field

[0001] The utility model relates to automobile production and assembly industries, in particular to a transmission lifting mechanism capable of realizing flexible adjustment. Background Art

[0002] In automobile welding production lines, it is often necessary to transport the front and rear floor panels. This type of transport is not just horizontal movement, but sometimes also requires the front and rear floor panels to move up and down in the longitudinal direction.

[0003] For example, in a welding production line, it is necessary to transfer the front and rear base plates from one line to another. When they are in place and need to be unloaded, or when other front and rear base plates need to be loaded for welding, the conveyor device needs to be able to move the workpiece horizontally and vertically.

[0004] The traditional transmission and lifting device has a complex overall structure and a large size. After the horizontal movement is in place, the speed of driving the workpiece to move up and down is relatively slow. Moreover, all the lifting mechanisms of traditional equipment work synchronously at the same time, driving the workpiece to move in the longitudinal direction, which has poor flexibility.

[0005] Therefore, a method or device that can solve the above problems is needed. Summary of the Invention

[0008] The lifting mechanism 4 includes a support frame 8 directly connected to the slide 3, and a lifting frame 10 is movably connected to the support frame 8 through a second slide rail and slider mechanism 9. A lifting motor 11 is provided on the support frame 8, and the output end of the lifting motor 11 is connected to the input end of the gearbox. The output end of the gearbox is provided with a lifting active tooth 12, and the lifting active tooth 12 is engaged with a longitudinal rack 13. The longitudinal rack 13 is provided on the lifting frame 10.

[0009] The lifting frame 10 is provided with a longitudinally distributed scale 14 , and the support frame 8 is fixedly provided with a scale pointer 15 , the scale pointer 15 corresponding to the position of the scale ruler 14 .

[0016] This type of structural form of a flexibly adjustable transmission and lifting mechanism has a simple structure, an ingenious design, and a reasonable layout. It is designed to address the problems existing in the operation of traditional lifting and conveying devices by adopting a special structure. It drives multiple lifting mechanisms to move through a base plate, thereby driving the workpiece supported by the lifting mechanism to move in the horizontal direction. At the same time, each lifting mechanism can work independently, driving the supported workpiece to move in the longitudinal direction, thereby realizing the horizontal and vertical transportation of the workpiece. Since each lifting mechanism can move independently, this mechanism can perform more complex transportation actions. Compared with the traditional integral lifting structure, it has higher flexibility and can adapt to more complex working conditions. In addition, the manufacturing process of the transmission and lifting mechanism is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The specific implementation of the present invention will be described below with reference to the accompanying drawings. Figures 1 to 5 As shown: A transmission lifting mechanism that can be flexibly adjusted includes a base plate 1 as a basis, a slide plate 3 is slidably connected to the base plate 1 through a first slide rail and slider mechanism 2, a plurality of lifting mechanisms 4 are arranged on the slide plate 3 at equal intervals, a horizontal rack 5 is arranged on the side of the slide plate 3, a horizontal motor 6 is arranged on the base plate 1, the output end of the horizontal motor 6 is connected to the input end of the gearbox, the output end of the gearbox is provided with a horizontal driving tooth 7, the horizontal driving tooth 7 and the horizontal rack 5 are meshed with each other,

[0023] The lifting mechanism 4 includes a support frame 8 directly connected to the slide 3, and a lifting frame 10 is movably connected to the support frame 8 through a second slide rail and slider mechanism 9. A lifting motor 11 is provided on the support frame 8, and the output end of the lifting motor 11 is connected to the input end of the gearbox. The output end of the gearbox is provided with a lifting active tooth 12, and the lifting active tooth 12 is engaged with a longitudinal rack 13. The longitudinal rack 13 is provided on the lifting frame 10.

[0024] The lifting frame 10 is provided with a longitudinally distributed scale 14 , and the support frame 8 is fixedly provided with a scale pointer 15 , the scale pointer 15 corresponding to the position of the scale ruler 14 .

[0025] The support frame 8 is provided with an upper sensor 16 and a lower sensor 17. When the lifting frame 10 is in the upper limit position, the upper sensor 16 is triggered. When the lifting frame 10 is in the lower limit position, the lower sensor 17 is triggered.

[0026] A support frame is provided on the bottom plate 1 , on which a first felt gear 18 is rotatably supported. The first felt gear 18 is meshed with the horizontal active gear 7 .

[0027] A support frame is provided on the support frame 8 , and a second felt gear 19 is rotatably supported on the support frame. The second felt gear 19 is meshed with the lifting active gear 12 .

[0028] A clamp assembly 20 is provided on the top of the lifting frame 10 .

[0029] There are multiple slide plates 3 , and adjacent slide plates 3 are fixedly connected via connecting pieces. The horizontal rack 5 is arranged on the slide plate 3 closest to the horizontal motor 6 .

[0030] The working process of the flexible adjustable transport lifting mechanism of the embodiment of the present invention is as follows: a plurality of workpieces to be transported are placed on top of different lifting frames 10, and clamped and fixed by the clamp assembly 20.

[0031] The control system sends a signal to the horizontal motor 6 in this mechanism, and the horizontal motor 6 drives the horizontal active gear 7 to rotate. The horizontal active gear 7 drives the horizontal rack 5 and the slide 3 connected thereto to move together, thereby realizing the relative movement between the slide 3 and the base plate 1 in the horizontal direction. In actual work, when it is necessary to transport multiple workpieces at the same time, the number of slides 3 (and the lifting mechanisms 4 thereon) can be selected as needed, and the adjacent slides 3 can be fixedly connected to form an integrated structure using connecting parts. In this way, when the first slide 3 moves, it will drive all other slides to move together with it, thereby realizing the horizontal transmission of all workpieces.

[0032] When a workpiece needs to be driven to move in the longitudinal direction, a signal is sent to the lifting mechanism 4 supporting the workpiece through the control system, and the lifting motor 11 therein is started, which drives the lifting active gear 12 to rotate, and the lifting active gear 12 drives the longitudinal rack 13 and the lifting frame 10 connected thereto to move together, thereby realizing the relative movement between the lifting frame 10 and the support frame 8 in the longitudinal direction;

[0033] By controlling different lifting motors 11, independent lifting actions of different workpieces can be achieved;

[0034] When the lifting frame 10 is raised or lowered, the scale 14 also moves accordingly. The staff can judge the current relative height of the lifting frame 10 by observing the scale corresponding to the scale pointer 15;

[0035] When the lifting frame 10 is at the upper limit position, the upper sensor 16 is triggered, and when the lifting frame 10 is at the lower limit position, the lower sensor 17 is triggered. Based on this, the control system can determine the current height of a workpiece.

[0036] During operation, the first felt gear 18 lubricates the horizontal driving teeth 7 , and the second felt gear 19 lubricates the lifting driving teeth 12 .
