Description

Technical Field

[0001] The utility model relates to a multi-station synchronous lifting device, belonging to the technical field of mechanical automation. Background Technique

[0002] Automated mechanical production technology is closely related to systems engineering, computer technology, electronics, hydraulic and pneumatic technology, and automatic control technology. With the rapid development of industrial automation technology in China, the requirements for automation technology are increasing day by day. In recent years, the country's investment in the field of artificial intelligence has also gradually expanded, making the popularization of industrial automation an embodiment of the country's comprehensive strength.

[0003] Currently, commonly used automation technologies include robotic mechanisms, press-fitting mechanisms, rotating mechanisms, lifting mechanisms, etc. Among them, the lifting mechanism is often used in the processes of feeding, docking, or transferring in automated equipment, thus playing an important role in automated mechanical equipment. In the assembly line of mechanical automation products, in many working scenarios, it is necessary to simultaneously perform the lifting actions of multiple products. However, each lifting station requires an independent drive to perform the lifting operation. This not only increases the hardware cost and control cost but also easily leads to the problem of non-synchronous lifting. Therefore, there is an urgent need for a multi-station synchronous lifting device to solve the problems raised in the above background technique. Summary of the Utility Model

[0004] The content part of this application is used to briefly introduce concepts, which will be described in detail in the subsequent detailed implementation part. The content part of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0005] Aiming at the problems and deficiencies existing in the prior art, the purpose of the utility model is to provide a multi-station synchronous lifting device. By arranging a plurality of lifting mechanisms between the two side frame plates and using a driving wheel and a driving belt to make the plurality of lifting mechanisms synchronously perform the lifting operation, the production cost of the product is greatly reduced. To solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: It includes a plurality of lifting mechanisms. Each lifting mechanism includes a bottom plate. A guide rod passes through an opening on the bottom plate and is connected to a top plate. Below the top plate, an upper hinge plate is connected through an upper vertical plate. The upper hinge plate is hinged to a lower hinge plate connected to the upper part of the bottom plate through a lower vertical plate. A frame plate is arranged on the side of the lifting mechanism, and a plurality of mounting holes are opened on the frame plate to pass through and connect the driving shaft. The driving shaft also passes through an opening on the lower vertical plate and is connected. One end of the driving shaft is connected to the output shaft of a driving motor. Driving wheels are sleeved on the outer sides of the driving shafts, and driving belts are sleeved on the outer sides of the driving wheels to connect and transmit power.

[0007] Preferably, the frame plates are symmetrically arranged on both sides, and the two frame plates are respectively connected to the two side edges of the bottom plate. The two frame plates are symmetrically arranged on both sides of the lifting mechanism, and the symmetrically arranged frame plates are both connected and installed on the bottom plate in the lifting mechanism. During use, the drive shaft passes through the frame plates on both sides and the lifting mechanism in sequence, which can improve the stability of the lifting mechanism during operation. And it can be connected and fixed to other peripheral mechanisms through the frame plates, further improving the stability and safety of the present utility model during use.

[0008] Preferably, a linear bearing is added at the connection between the bottom plate and the guide rod. During the operation of the lifting mechanism, the top plate is connected to the guide rod and moves up and down in the opening on the bottom plate. Since the linear bearing is a linear motion system with high precision and small frictional resistance, it can achieve infinite linear motion when used in conjunction with the guide shaft. In the present utility model, the linear bearing can play a guiding role to ensure that the top plate and the bottom plate are not easily offset during the lifting motion. At the same time, it can also assist in bearing a certain lifting load, supporting the weight and pressure of the top plate during the linear motion. It also reduces the wear at the connection between the guide rod and the bottom plate.

[0009] Preferably, driven wheels are also sleeved outside the adjacent drive shafts, and a driven belt is sleeved outside the two driven wheels for connection and transmission. Since multiple lifting mechanisms are provided, the drive shafts are also correspondingly provided in multiple numbers. At least driven wheels are sleeved outside the ends of the adjacent drive shafts, and these two driven wheels are sleeved and connected by a driven belt. Through the driven wheels and the driven belt, the simultaneous transmission between multiple drive shafts can be completed, enabling multiple lifting mechanisms to achieve synchronous lifting actions, improving the consistency during the lifting operation and the production efficiency of the product.

[0010] Preferably, an auxiliary bearing is added at the connection between the frame plate and the drive shaft. Generally, the function of a bearing is to reduce friction, so that the rotation is smoother to achieve energy consumption reduction. That is, in the present utility model, the added auxiliary bearing can support the continuous rotation of the drive shaft and reduce the friction between the drive shaft and the frame plate, so as to extend the service life of both.

[0011] Preferably, a clearance fit is adopted between the drive shaft and the auxiliary bearing. A clearance fit is to retain a certain clearance between the bearing and the shaft or the bearing seat. Here, through the clearance fit between the drive shaft and the auxiliary bearing, the auxiliary bearing can have a better tolerance for the torsion and deflection of the drive shaft, thereby improving the service life of the auxiliary bearing.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] The utility model has the characteristics of simple structure and convenient operation, can realize the operation of jacking products at multiple stations, and can ensure the synchronism, stability and safety during its work. The utility model places a plurality of jacking mechanisms in the middle of symmetrically arranged frame plates, and sequentially passes a driving shaft through the frame plates and the jacking mechanisms for connection. When a driving motor is connected to drive the driving shaft to rotate, the driving shaft can drive an upper hinge plate and a lower hinge plate to drive the top plate to jack up. At the same time, driving wheels are sleeved on the outer sides of the driving shafts, and driving belts are sleeved on the outer sides of the driving wheels for connection and transmission. In addition, driven wheels are sleeved on the outer sides of adjacent driving shafts, and driven belts are sleeved on the outer sides of the two driven wheels for connection and transmission. Thus, it can ensure that a plurality of jacking mechanisms can achieve accurate synchronous jacking actions, thereby further improving the consistency during jacking and the production efficiency of products.

Driving wheels 7 are sleeved on the outer sides of the driving shaft 2, and a driving belt 3 is sleeved on the outer sides of the driving wheels 7 for transmission connection.
