Abstract
The utility model discloses a kind of height adjustable screw jack, its structure includes screw rod, pedestal, dogbolt, rotating nut, raising threaded mandrel, the screw rod is fixedly connected with raising threaded mandrel, the pedestal is connected with screw flight, the dogbolt is connected with base runner, and the rotating nut is connected with screw flight, and the pedestal is made up of stop through hole, screwed hole, counter sink, the stop through hole is fixedly connected with pedestal, and the screwed hole is fixedly connected with counter sink.A kind of height adjustable screw jack of the present utility model, screw rod is set to move up and down using the rotation of nut, the rotation of nut makes screw rod be moved up and down in the case of non-rotary, avoid part and skew is produced on screw rod, improve the time that part blank is wasted in trimming process, and practicality simple to operate.
Description
Technical field
The utility model is a kind of height adjustable screw jack, belongs to screw jack technical field.
Background technology
The production process of machine refers to all processes that product is made from raw material (or semi-finished product).For production of machinery
Transport and preservation including raw material, the preparation of production, the manufacture of blank, the processing and heat treatment of part, the assembling of product and
Debugging, the content such as paint and packaging.The content of production process is quite varied, the principle and method of modern enterprise system analysis engineering
Tissue production and Instructing manufacture, regard production process as a production system with input and output.
During machined part, frequently encounter part blank irregularly, benchmark need to be processed to part
Centering, existing structure reaches the purpose of adjustment height using being that screw thread rotation moves up and down screw rod, and prior art lacks
Fall into：Screw thread also rotates together during rotation, and part is unstable on screw rod, part is produced skew.
Utility model content
In view of the deficienciess of the prior art, to be to provide a kind of height adjustable screw thread very heavy for the utility model purpose
Top, to solve.
To achieve these goals, the utility model is to realize by the following technical solutions：A kind of adjustable height
Screw jack, its structure include screw rod, pedestal, dogbolt, rotating nut, raising threaded mandrel, the screw rod with rise
Rise threaded mandrel to be fixedly connected, the pedestal is connected with screw flight, and the dogbolt is connected with base runner, it is described to rotate
Nut is connected with screw flight, and the pedestal is made up of stop through hole, screwed hole, counter sink, and the stop through hole is consolidated with pedestal
Fixed connection, the screwed hole is fixedly connected with counter sink.
Further, the rotating nut is connected by screw rod with base runner.
Further, the rotating nut is made up of endoporus.
Further, the endoporus is provided with screw thread.
Further, the raising threaded mandrel is made up of conehead.
A kind of height adjustable screw jack of the present utility model, does screw rod using the rotation of nut and transports up and down
Dynamic, the rotation of nut makes screw rod be moved up and down in the case of non-rotary, it is to avoid part produces skew on screw rod, raising
The time that part blank is wasted in trimming process, and practicality simple to operate.
Brief description of the drawings
By reading the detailed description made with reference to the following drawings to non-limiting example, other spies of the present utility model
Levy, objects and advantages will become more apparent upon：
Fig. 1 is a kind of complete section structural representation of height adjustable screw jack of the utility model；
In figure：Screw rod -1, pedestal -2, dogbolt -3, rotating nut -4, raising threaded mandrel -5, stop through hole -201,
Screwed hole -202, counter sink -203, endoporus -401, conehead -501.
Embodiment
To be easy to understand technological means, creation characteristic, reached purpose and effect of the utility model realization, below
With reference to embodiment, the utility model is expanded on further.
Referring to Fig. 1, the utility model provides a kind of height adjustable screw jack technical scheme：Its structure includes
Screw rod 1, pedestal 2, dogbolt 3, rotating nut 4, raising threaded mandrel 5, the screw rod 1 is fixed with raising threaded mandrel 5 to be connected
Connect, the pedestal 2 is threadedly coupled with screw rod 1, the dogbolt 3 is flexibly connected with pedestal 2, the rotating nut 4 and screw rod 1
Threaded connection, the pedestal 2 is made up of stop through hole 201, screwed hole 202, counter sink 203, the stop through hole 201 and pedestal
2 are fixedly connected, and the screwed hole 202 is fixedly connected with counter sink 203, and the rotating nut 4 passes through screw rod 1 and the activity of pedestal 2
Connection, the rotating nut 4 is made up of endoporus 401, and the endoporus 401 is provided with screw thread, and the raising threaded mandrel 5 is by conehead
501 compositions.
In progress in use, making screw rod 1 move up and down using the rotation of nut, screw rod 1 does not rotate, rotating nut 4
Rotation makes screw rod 1 be moved up and down in the case of non-rotary, it is ensured that part will not produce horizontal inclined when moving up and down
Move, improve the time that part blank is wasted in trimming process, and practicality simple to operate.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above, for
For those skilled in the art, it is clear that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and without departing substantially from this
In the case of the spirit or essential attributes of utility model, the utility model can be realized in other specific forms.Therefore, no matter
