The invention discloses a lifting platform for detecting a precise sample. The lifting platform comprises a lifting platform base, a guiding pillar, a linear bearing, a limiting assembly, a triggeringassembly, an object loading platform, a ball screw pair, a bearing assembly, a casing pipe, a motor base, a servo motor, a harmonic reducer, a flange shaft and a coupler. The base is of a hollow cylindrical structure, a driving unit and a guiding unit are arranged inside the base, and the structure is compact. A single large-diameter linear bearing is adopted to conduct guiding, and the guiding precision and the motion stability can be improved; through the cooperation of dowels and long slots in the guiding pillar, the rotation of the guiding pillar is limited, and through the cooperation ofnuts, the rotation of a lead screw is turned into longitudinal movement of the guiding pillar. Loading force and driving force are collinear, and the phenomenon of unbalance loading can be removed. By selecting the servo motor, the harmonic reducer, and the ball screw pair to be combined, the transmission ratio is large, the output torque is large and the transmission accuracy is high. The lifting platform for detecting the precise sample is compact in structure, high in movement precision and high in bearing stability, and has high application and popularization value.
Description
technical field [0001] The invention relates to the technical field of lifting platform equipment, in particular to a precision sample detection lifting platform. Background technique [0002] At present, the sample lifting and adjusting table used in the field of optical inspection is mainly driven by a screw, and the guiding methods include linear guide rail type and scissor type, and there are various derived structures. [0003] The guide rail type lifting table is generally driven by a single screw rod, and the double guide unit ensures the linear movement accuracy. The accuracy of parts and assembly is higher, and the overall structure is complex and bulky. The scissor lift table has a relatively compact structure and a large load capacity, but there are many hinge units and the guiding precision is not high. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a precision sample detection lifting platform for...
