Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to an electrical lifting mechanical device. Background Art

[0002] A manipulator is an automatic device that can imitate certain movements of human hands and arms, and is used to grab, carry objects or operate tools according to a fixed program. It is characterized by being able to complete various expected operations through programming, and has the advantages of both human and mechanical machines in terms of structure and performance. However, at present, there are more single-arm ones, and the development of double-arm ones, especially those suitable for model processing, is relatively rare, and further research and development and improvement are needed.

[0003] For example, Chinese patent (CN202321267812.3) discloses a mechanical and electrical adjustment and positioning device, which relates to the technical field of mechanical and electrical adjustment devices, including an electrical positioning carrier, on which two movable plates are slidably installed, and a square slider is installed at the bottom of the movable plate. The utility model, through the arrangement of structures such as movable plates, pressure plates and reset springs, when it is necessary to lift and adjust the mechanical and electrical equipment, it is placed on the pressure plate, and its own weight drives the pressure plate to slide down, and the sliding of the pressure plate drives the sliding rod to slide down, and the sliding of the sliding rod drives one end of the connecting rod to rotate and slide down, and the other end rotates and slides to the middle due to the limiting effect of the limiting hole and the T-shaped slide groove, thereby driving the movable plate to slide to the middle, and then driving the clamping plate to approach and clamp the mechanical and electrical equipment, and the rubber pad increases the friction to prevent the mechanical and electrical equipment from shaking, thereby realizing that the mechanical and electrical equipment can be placed on the pressure plate to limit and fix it, and prevent displacement during the lifting process, which is convenient and quick.

[0004] The above-mentioned lifting device uses a single lead screw to achieve lifting. When using a single lead screw for lifting, if the load on both sides is unbalanced, it will cause different forces on the respective drive nuts, thereby affecting their synchronization. This may cause the nut on one side to move faster than the other side, resulting in poor synchronization. In addition, the above-mentioned device is large in size, and the lifting height depends only on the length of the lead screw, making it difficult to flexibly adjust the lifting height. If the lifting height needs to be changed, the entire lead screw may need to be replaced, increasing the cost and complexity of the modification. In view of the above-mentioned problems, an electrical lifting mechanical device is proposed to solve them. Utility Model Content

Through the rotation of the synchronous rod 3, the first bevel gears 4 on both sides can be driven to rotate synchronously at the same time. This design ensures the synchronous rotation of the threaded screws 8 on both sides, thereby realizing the synchronous lifting of the threaded seats 10 on both sides. The left and right sides of the upper surface of the mounting housing 2 are fixedly connected to the fixed plates 6, the inner sides of the two fixed plates 6 are fixedly connected to the fixed seats 7, the bottoms of the two fixed seats 7 are rotatably connected to the threaded screws 8, the surfaces of the two threaded screws 8 are threadedly connected to the threaded seats 10, and a synchronous lifting assembly 11 is arranged between the two threaded seats 10.

At the same time, the threaded connection has high precision, which can achieve precise lifting control.

[0024] Specifically, the synchronous lifting component 11 includes a base plate 1101, and the left and right sides of the base plate 1101 are fixedly connected to the threaded seats 10 on both sides respectively. Racks 1102 are arranged at the four corners of the upper surface of the base plate 1101, and the racks 1102 are slidably connected to the base plate 1101.

The meshing design of the rack 1102 and the driving gear 1106 enables the rack 1102 to be lifted and lowered stably, thereby ensuring the smooth movement of the storage plate 1103.

[0026] Specifically, the surfaces of the two rotating shafts 1105 are fixedly connected with synchronous wheels 1107, and the two synchronous wheels 1107 are connected through transmission of synchronous belts 1108.
