Description

Robot second grade lifting mechanism Technical Field The utility model relates to the technical field of robots, in particular to a two-stage lifting mechanism of a robot. Background Current multiple lift mechanisms generally tend to use multiple independent power sources in design to ensure that the power supply during each stage of lift is independently handled. However, the use of multiple power source transmissions, while exhibiting significant advantages in terms of overall efficiency, inevitably increases the high degree of dependence on the accuracy of power source control. This increased dependence means that small deviations in the output of any one power source during the two-stage lifting of the mechanism may cause serious effects on the accuracy of the linear motion of the overall system. Such fluctuations in accuracy not only reduce the efficiency of operation, but may also cause a series of unnecessary mechanical failures. Furthermore, the parallel use of multiple power sources also means that the mechanism needs to carry more weight, which undoubtedly increases the overall weight of the mechanism, thereby limiting the flexibility of the mechanism to some extent. In order to reduce the number of power sources, most of the multiple Cheng Taisheng mechanisms widely adopt transmission mechanisms with mutually matched gears and racks. The design utilizes the meshing action between the gear and the rack to transfer power from one stage to the next stage, thereby completing the lifting action of each stage. However, it should be noted that the manufacturing cost is relatively high, which is not only reflected in the selection of raw materials, but also in the improvement of processing precision and processing complexity. This high manufacturing cost undoubtedly increases the investment in the early stages, which can be an unbearable burden for budget-limited projects. However, during long term use, rack and pinion systems, particularly open racks and pinions, are also relatively complex to maintain and replace. Due to the influence of external factors such as dust, impurities and the like in the working environment, the abrasion of the open gear rack is particularly remarkable, so that the service life of the open gear rack is shortened, and the maintenance cost is increased. For operation and maintenance personnel, the difficulty and the intensity of the operation are certainly increased, and simultaneously, higher requirements are also put on the professionality and timeliness of the operation and maintenance work.
