Description
(1) technical field
The utility model relates to a kind of elevating mechanism, and especially a kind of instrument for measuring three-dimensional profile of object elevating mechanism is used to control the lifting of instrument for measuring three-dimensional profile of object.
(2) background technology
At present, the guide tracked or card slot type of the many employings of the elevating mechanism of instrument for measuring three-dimensional profile of object causes measuring instrument to be easy to generate shake when lifting, influences the measuring accuracy of measuring instrument; And conventional measuring instrument needs practical two motors lifting and the rotation of control survey instrument respectively usually with elevating mechanism, causes measuring instrument complex structure, cost high.
(3) utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides not only simple in structure, cheap but also lifting is steady, measuring accuracy is high instrument for measuring three-dimensional profile of object elevating mechanism.
The purpose of this utility model is achieved in that a kind of instrument for measuring three-dimensional profile of object elevating mechanism, and described elevating mechanism includes dustproof base, loading plate and lifting rotary components; Described dustproof base center is provided with a screw mandrel, described dustproof base the right and left is symmetrically arranged with guide pillar, described loading plate center is provided with a perforate, described lifting rotary components is arranged in the perforate, described loading plate the right and left respectively is provided with a linear axis and holds, and described loading plate is placed on respectively on screw mandrel and the guide pillar by lifting rotary components and linear bearing; Described lifting rotary components includes transmission nut, bearing and main bearing, and described transmission nut revolves to be put on screw mandrel, and described main bearing links to each other with transmission nut by bearing, and described main bearing is fixedlyed connected with loading plate.
The beneficial effects of the utility model are: during measurement, transmission nut is in the process that drives the measuring instrument rotation, carry out the spiral upward movement along screw mandrel, rotatablely moving of level changed into vertical displacement movement, therefore in the use of reality, only need the rotation and the lifting of motor control survey simultaneously instrument, simplified device structure, saved cost; Owing to adopted linear bearing, the frictional resistance during motion changes rolling friction into by sliding friction, greatly reduces friction force, makes steadily lifting of measuring instrument to have reduced shake simultaneously, has improved the precision of measuring.
