Problems solved by technology
[0002] With the development of science and technology, some factories use composite robots formed by loading operating mechanisms (such as mechanical arms) on AGV trolleys to carry out operations. In order to adapt to uneven road surfaces, most of the current AGV trolleys are equipped with spring suspension systems. Although this structure solves the grip of the wheels and the adaptability of the AGV trolley to the ridges on the ground, it also brings a fatal flaw to the composite robot, that is, when the composite robot goes to the station to work, the suspension system of the chassis will suffer Large shaking occurs, which seriously affects the working accuracy of the upper robotic arm

Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings.
[0034] Such as Figure 1 to Figure 9 A trolley shown as a non-elastic element capable of switching between rigid and flexible states includes a frame 1 , a rigid-flexible switching module 2 and two sets of wheels 3 .
[0035] The wheel set 3 includes an axle 31, two sets of wheels 32, a swing limit pin 33, a steering module 34, and a stroke assembly 35. The wheels 32 include a pivot plate 321 and a runner 322. The pivot plate 321 is in an inverted U shape, turning The wheels 322 are pivotally connected to the pivot plate 321 , and the two groups of wheels 32 are respectively arranged at both ends of the axle 31 through the pivot plate 321 .
[0036] Each wheel set 3 includes two swing limit pins 33, and each axle 31 is symmetrically provided with two limit grooves 310, and the two swing limit pins 33 are matched with the two limit grooves 310 respectively. One end of...

The invention discloses a trolley capable of switching between rigid and flexible states without elastic elements, and relates to the technical field of mobile trolleys. The solution includes a vehicle frame, a rigid-flexible switching module and two sets of wheels. The wheels set includes an axle and two sets of wheels. , the two sets of wheels are set at both ends of the axle respectively; the rigid-flex switching module includes two sets of gear sets, brake shaft, brake gear and electromagnetic brake, one end of the brake shaft is connected with the electromagnetic brake, and the brake shaft The other end passes through the frame and is fixedly connected to the wheel center of the brake gear; the gear set includes a half shaft and a side gear, one end of the half shaft is fixedly connected to the wheel center of the side gear, and the other end of the half shaft passes through the wheel center of the brake gear. frame, and is fixedly connected in the middle of the axle, and the half-shaft gear and the brake gear mesh with each other; the invention realizes that the chassis becomes flexible when the trolley is moving, can pass the ditch and keep the balance of the top-loading operation mechanism to the greatest extent, and the chassis when it stops Rigidity, so that the upper body operation mechanism can achieve the purpose of high-precision operation.
Description
technical field [0001] The invention relates to the technical field of mobile trolleys, in particular to a trolley without elastic elements that can switch rigid and flexible states. Background technique [0002] With the development of science and technology, some factories use composite robots formed by loading operating mechanisms (such as mechanical arms) on AGV trolleys to carry out operations. In order to adapt to uneven road surfaces, most of the current AGV trolleys are equipped with spring suspension systems. Although this structure solves the grip of the wheels and the adaptability of the AGV trolley to the ridges on the ground, it also brings a fatal flaw to the composite robot, that is, when the composite robot goes to the station to work, the suspension system of the chassis will suffer A large shake is generated, which seriously affects the working accuracy of the upper mechanical arm. Contents of the invention [0003] The purpose of the present invention i...
