Abstract
The utility model provides a kind of lead screw pair with automatic cleaning ability, including lead screw body, nut body, lead screw body described in central axes cutting along the lead screw body is divided into two to form two separation lead screw bodies, and the separation lead screw body is screwed with the nut body internal and external threads and connect.The utility model has the advantages that making screw pair operating unobstructed.The screw thread pair of sliding friction is converted to rolling friction campaign, and the present apparatus is not allowed to be also easy to produce sundries siltation, cleaning is convenient, and structure is simple, easy to make.
Description
Technical field
The utility model relates to lead screw more particularly to a kind of lead screw vice mechanisms.
Background technique
Screw and nut are attached by the way of directly screwing connection under normal conditions, mechanism energy in this way
It realizes the rotary motion that the rotary motion of thread spindle is converted to nut, can be oriented to for workbench using such characteristic
Movement.The fricting movement between above-mentioned screw thread pair is sliding friction under normal conditions.Now there is internal and external circulation type roller silk on the market
Above-mentioned sliding friction is converted to rolling friction by thick stick pair of nut, but structure is complicated for such ball guide screw nat, system
Trouble is made, commutator is in addition also used, commutator is easy to happen damage in the long-term use process, shortens ball-screw spiral shell
Female secondary service life.
Summary of the invention
The utility model overcomes the shortcomings of that background technique provides a kind of rolling friction type lead screw, designs and develops the present apparatus
The screw thread pair of sliding friction is converted to rolling friction campaign by purpose, and the present apparatus is not allowed to be also easy to produce sundries siltation, cleaning side
Just, structure is simple, easy to make.
The utility model provides following technical proposals: a kind of lead screw pair with automatic cleaning ability, including lead screw body,
Nut body 2, which is characterized in that lead screw body described in the central axes cutting along the lead screw body is divided into two to form two separation lead screws
Body 1, the separation lead screw body 1 are screwed with 2 internal and external threads of nut body and are connect.
The utility model has the beneficial effects that cylindrical type lead screw body is cut by way of wire cutting along axis, one point
It is respectively arranged in two nut bodies 2 for two, forms two pair of nut.Due to being separated with semicircle between separating between lead screw body 1 and nut body 2
Column cavity 5, during separation lead screw body 1 is spinned along nut body 2 and moved, the semicolumn cavity 5 is miscellaneous for storing
Object, to be also convenient for the storage and discharge of sundries.So that screw pair operating is unobstructed.The screw thread pair of sliding friction is converted to
Rolling friction campaign, and the present apparatus is not allowed to be also easy to produce sundries siltation, and cleaning is convenient, and structure is simple, easy to make.
Detailed description of the invention
Fig. 1 is a kind of schematic perspective view of lead screw pair with automatic cleaning ability described in the utility model.
Fig. 2 is a kind of planar structure schematic diagram of lead screw pair with automatic cleaning ability.
Specific embodiment
The utility model is further described below in conjunction with attached drawing and specific embodiment.
Fig. 1, in 2: separation lead screw body 1, nut body 2, semicolumn cavity 3.
A kind of lead screw pair with automatic cleaning ability, including lead screw body, nut body 2, along the central axes of the lead screw body
Lead screw body described in cutting is divided into two to form two separation lead screw bodies 1, the separation lead screw body 1 and spiral shell inside and outside the nut body 2
Line screws connection.
Processing spec: cylindrical type lead screw body is cut by way of wire cutting along axis, is divided into two and installs respectively
In two nut bodies 2, two pair of nut are formed.Due to being separated with semicolumn cavity 3 between separating between lead screw body 1 and nut body 2, dividing
It spins from lead screw body 1 along nut body 2 during moving, the semicolumn cavity 3 is for storing sundries, to be also convenient for
The storage and discharge of sundries.So that screw pair operating is unobstructed.
