Abstract
The utility model relates to a lead-screw and semi-nut mechanism. In the precision instrument, the rail motion of the manual operation work bench is divided into a fast motion and a micromotion, which is realized by using the mechanism of the half nut or the feeding rod-roller, etc. The problems of many component parts, big shape structure size, inconvenient processing, loading, changing, etc. Are mostly existed. The lead-screw and semi-nut mechanism comprises a body 1, a semi-nut 3 that is arranged in the body 1, a spring 4 that is arranged in the semi-nut 3; the bottom of the semi-nut 3 is pressed on the lead-screw 8, and a shaft 8 of the pinion 7 is arranged in the body 1; the pinion 7 is meshed with one end of the semi-nut 3; one end of the pinion shaft 8 is provided with a sleeve 9, and is arranged in one end of the body 1; the other end of the pinion shaft 8 is fixedly connected with a handgrip 5 by a pin 6; screws 2 are arranged in the body 1 and the hole of the semi-nut 3. The utility model is used in the rail motion of the manual operation work bench of the precision instrument.
Description
Technical field: the utility model relates to a kind of leading screw and half-nut mechanism.
Background technology: in precision instrument, for manual workbench, guide rail movement generally needs fast moving and fine motion dual mode to improve the accuracy of measuring efficient and location, mechanisms such as general use clasp nut or feed rod-roller realize, but mostly exist number of spare parts many, contour structure size is big, processes and debug problems such as inconvenience.
Summary of the invention: the purpose of this utility model provides a kind of simple in structure, uses leading screw easy to adjust and half-nut mechanism.
Above-mentioned purpose realizes by following technical scheme:
Leading screw and half-nut mechanism, its composition comprises: main body and dress half-nut within it, in the described half-nut spring is housed, the bottom of described half-nut is pressed on the leading screw, axle with pinion is housed in the described main body, the one end engagement of described pinion and described half-nut, one end of described pinion shaft is equipped with cover and is contained in the end of described main body, the other end of described pinion shaft is fixedlyed connected with handgrip with pin, in the hole of described main body and described half-nut screw is housed.
Above-mentioned leading screw and half-nut mechanism, the endoporus of described half-nut and described main body is a matched in clearance.
Above-mentioned leading screw and half-nut mechanism, described screw is a stop screw.
This technical scheme has following beneficial effect:
1. leading screw of the present utility model and half-nut mechanism, be to be used for a kind of transmission mechanism that precision instrument is adjusted guide rail movement, the half-nut of this product can be realized the disengagement fully of leading screw and nut with the shortest displacement along radially folding of leading screw, reduces the generation of scraping dental phenomenon.
2. the half-nut of this product is pressed on the leading screw by spring, and by the axial drive gap of elimination with precision lead screw, when guaranteeing to rotate precision lead screw, main part is axially done fine motion along precision lead screw, has realized the precision positioning of guide rail.
3. this product is controlled joint, the disengagement of leading screw and half-nut by gear-tooth bar mode, has little, the easy to use characteristics of active force.
4. the steady pin of this product connects together pinion and handgrip, and the cover on its gear shaft can limit and make the gear shaft beat.
5. the stop screw of this product suffers restraints the stroke of half-nut in main body, though user mode does not have effect, and can be convenient for assembly.
6. the folding of the half-nut of this product is that mode by the gear driven tooth bar realizes, as long as the effect that leading screw can bear spring force, just can improve the ability of entire mechanism carry-over moment, effectively prevent to jump tooth and reduce forward and reverse idle running by suitably increasing the method for spring force.

Embodiment 2:
Above-mentioned leading screw and half-nut mechanism, described half-nut 3 is a matched in clearance with the endoporus of described main body 1.
Embodiment 3:
Above-mentioned leading screw and half-nut mechanism, described half-nut 3 is little matched in clearance with the endoporus of described main body 1, by described spring 4, described half-nut 3 is crushed on the described precision lead screw 8, when rotating described precision lead screw 8, described main body 1 part can axially be done fine motion along described precision lead screw 8, realizes the accurate location of guide rail; When rotating described handgrip 5, described pinion 7 drives described half-nut 3, compressing described spring 4 moves upward, described half-nut 3 is thrown off fully with described precision lead screw 8, described main body 1 part is moved no longer restricted along described precision lead screw 8 axis directions, can do fast moving freely.
Claims (3)
1. leading screw and half-nut mechanism, its composition comprises: main body and dress half-nut within it, it is characterized in that: in the described half-nut spring is housed, the bottom of described half-nut is pressed on the leading screw, axle with pinion is housed in the described main body, the one end engagement of described pinion and described half-nut, one end of described pinion shaft is equipped with cover and is contained in the end of described main body, the other end of described pinion shaft is fixedlyed connected with handgrip with pin, in the hole of described main body and described half-nut screw is housed.
