Abstract
Gapless high accuracy safety lift, including the lead screw, bear the ring flange, the drive worm, bear copper turbine and casing, bear the ring flange and install at the lead screw top, the drive worm with bear the copper turbine and place the casing in, the drive worm promotes to bear the copper turbine rotation, the thread that bears the copper turbine makes the lead screw carry out displacement from top to bottom, a plurality of anticreep safety nuts are arranged in respectively through a support guide pillar and are born the copper turbine top, an adjusting nut is connected and is being born the copper turbine top, bear copper turbine and adjusting nut respectively with the different contact surface contact of lead screw. The adjusting nut and the bearing copper worm gear are adjusted together, so that the lead screw is meshed with the bearing copper worm gear thread in the bearing direction, and the lead screw is meshed with the adjusting nut thread in the non-bearing direction, thereby achieving the meshing state of the upper surface and the lower surface of the lead screw, eliminating the gap between the bearing copper worm gear and the lead screw, and having the advantages of simple structure and high positioning precision.
Description
Technical Field
The utility model belongs to the technical field of automation, and particularly relates to a gapless high-precision safety elevator.
Background
The screw rod lifter can accurately control and adjust the lifting or propelling height according to a certain program, can be directly driven by a motor or other power, can also be manually driven, has the advantages of compact structure, small volume, light weight, wide power source, low noise, convenient installation, flexible use, multiple functions, multiple matching forms, high reliability, long service life and the like, and can be widely applied to various industries such as machinery, metallurgy, building, chemical engineering, medical treatment, culture and sanitation and the like. The lead screw of current lead screw lift bears copper worm wheel and lead screw cooperation back when bearing copper worm wheel in the motion process with bearing copper worm wheel, bears and has the clearance between copper worm wheel and the lead screw, for eliminating the clearance when the lead screw is just reversing, bears the copper worm wheel and can produce the hysteresis quality when up-and-down motion, can cause like this to go up and down the positioning accuracy low, and the swing scheduling problem appears in the lift process, can't use in the place that requires high precision.
SUMMERY OF THE UTILITY MODEL
The utility model provides a gapless high-precision safety elevator, which aims to solve the problem that the precision is influenced by the gap between a bearing nut and a screw rod in the prior art.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
the utility model provides a zero clearance high accuracy safety lift, including the lead screw, bear the ring flange, the drive worm, bear copper worm wheel and casing, bear the ring flange and install at the lead screw top, the drive worm with bear the copper worm wheel and place in the casing in, the drive worm promotes to bear the copper worm wheel rotatory, the thread that bears the copper worm wheel makes the lead screw carry out displacement from top to bottom, a plurality of anticreep safety nuts arrange in through a support guide pillar respectively and bear copper worm wheel top, an adjusting nut is connected at bearing copper worm wheel top, bear copper worm wheel and adjusting nut respectively with the different contact surface contact of lead screw.
The working principle of the utility model is as follows: connect at bearing copper turbine top through adjusting nut, make and bear the different contact surface contact of copper worm wheel screw thread and lead screw, thereby reach gapless effect, link together anticreep safety nut and bearing copper worm wheel through the support guide pillar, and make it and bear and remain certain distance between the copper worm wheel, when worm wheel screw thread wearing and tearing to drop completely, anticreep safety nut can the bearing at once, make its lead screw be unlikely to drop completely, leave the time for maintenance and maintenance.
The adjusting nut and the bearing copper worm gear are adjusted together, so that the lead screw is meshed with the bearing copper worm gear thread in the bearing direction, and the lead screw is meshed with the adjusting nut thread in the non-bearing direction, thereby achieving the meshing state of the upper surface and the lower surface of the lead screw, eliminating the gap between the bearing copper worm gear and the lead screw, and having the advantages of simple structure and high positioning precision.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
Fig. 1 is a schematic structural view of the present invention.
In the figure, a lead screw 1, a bearing flange 2, a driving worm 3, a copper turbine 4, a thread 5, an anti-falling safety nut 6, a supporting guide post 7, an adjusting nut 8 and a machine shell 9 are arranged.
Detailed Description
As shown in the figure, a gapless high accuracy safety elevator, including lead screw 1, bear ring flange 2, drive worm 3, bear copper turbine 4 and casing 9, bear ring flange 2 and install at lead screw 1 top, drive worm 3 with bear the copper turbine 4 and place the casing in, the drive worm promotes to bear the copper turbine rotation, the thread 5 that bears the copper turbine makes lead screw 1 carry out displacement from top to bottom, a plurality of anticreep safety nuts 6 arrange in and bear copper turbine 4 top through a support guide pillar 7 respectively, an adjusting nut 8 is connected at and bears copper turbine 4 tops, bear copper turbine 4 and adjusting nut 8 respectively with the different contact surface contact of lead screw 1.
The working principle of the utility model is as follows: connect at bearing copper turbine top through adjusting nut, make and bear the different contact surface contact of copper worm wheel screw thread and lead screw, thereby reach gapless effect, link together anticreep safety nut and bearing copper worm wheel through the support guide pillar, and make it and bear and remain certain distance between the copper worm wheel, when worm wheel screw thread wearing and tearing to drop completely, anticreep safety nut can the bearing at once, make its lead screw be unlikely to drop completely, leave the time for maintenance and maintenance.
