Adjustable-pressure AGV driving mechanism

Abstract

The invention belongs to the technical field of AGVs and relates to an adjustable-pressure driving mechanism suitable for an AGV. The driving mechanism comprises a pressure adjusting device and a driving device. The pressure adjusting device comprises a linear bearing, a barrel rod, a clamping spring pillar, a bolt, nuts and a support plate frame. The linear bearing is provided with a shaft sleeve fixed under the support plate frame. The clamping spring pillar is sleeved with a spring, and a spring cushion block is arranged at the bottom of the clamping spring pillar. One end of the bolt is connected with a spring adjusting pressing plate and achieves looseness prevention through one nut. The other end of the bolt and the other two nuts press one end of the spring in screwing and combining modes, and deformation quantity of the spring is set. Screwing and combining of the barrel rod and the two round nuts make the spring cushion block fix the other end of the spring. The barrel rod is fixedly connected with a support base in the support plate frame through the clamping spring pillar. The driving mechanism is installed on the AGV so that the bearing limit of the AGV can be changed by adjusting pressure, the bearing range of the AGV is extended, and cost is reduced.

Description

technical field [0001] The invention relates to the field of AGV technology, in particular to a pressure-adjustable AGV driving mechanism. Background technique [0002] AGV has a history of more than 50 years since its invention. With the expansion of application fields, its types and forms have become various. At present, springs are generally installed above the driving mechanism of the AGV trolley for shock absorption, but the spring deformation is fixed. If there is only one drive unit on the AGV trolley, this design is effective; if two drive units are installed on the AGV trolley, the center of gravity of the cargo is not in the geometric center , the damping effect of the spring may fail, and the wheels may slip and spin.

Problems solved by technology

At present, springs are generally installed above the driving mechanism of the AGV trolley for shock absorption, but the spring deformation is fixed. If there is only one drive unit on the AGV trolley, this design is effective; if two drive units are installed on the AGV trolley, the center of gravity of the cargo is not in the geometric center , the damping effect of the spring may fail, and the wheels may slip and spin

[0003] At the same time, the deformation setting of the spring is related to the weight of the loaded goods. When the spring deformation is fixed, it can only carry a certain limit of goods. If the loaded goods are too heavy, the spring needs to be replaced, and another set of drive unit may even need to be replaced. , the cost increases
