Abstract
The utility model discloses a kind of high-precision overlength threaded lead screws, are applied in an electric machine, including a main body bar, the main body bar are assembled in the electric machine；And an external screw thread, the external screw thread are arranged on the main body bar, the external screw thread has an effective length, and the working unit stroke of the electric machine is directly proportional to the externally threaded effective length, and the range of the effective length is in 80-90mm.Since the externally threaded length of the main body bar, so that the utility model can be improved the precision of assembly, increases the working unit stroke range of the electric machine in 80-90mm, and improve the performance of motor.
Description
Technical field
The utility model relates to machinery equipment field more particularly to a kind of high-precision overlength threaded lead screws.
Background technique
Today of life is entered into precision instrument, utilization of the micro servo motor in security monitoring field is very general
And and driving screw is the critical component of micro-step motor.
Micro servo motor is to rotate to drive driving screw screw thread rotation by rotor, then by screw-driven, ultimately form
The linear motion of screw thread upper cap nut.
With regard to focusing with micro servo motor in monitoring camera, with the intelligentized development of camera, to camera shooting
There has also been new requirements for the focusing range of head.By taking the super long distance camera being mounted at the top of high building as an example, this camera for
The requirement for border depth of focusing is high, in current programme, is more than the accurate driving screw of 50mm due to not having reach, can only select
The methods of second level focusing, so that structure is extremely complex, bulky, system is fragile.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of high-precision overlength threaded lead screw, so that super remote
Away from camera, the reach of the driving screw can satisfy the operation of single servo motor.
In order to solve the above-mentioned technical problem, the utility model provides technical solution below:
A kind of high-precision overlength threaded lead screw is applied in an electric machine, comprising:
One main body bar, the main body bar are assembled in the electric machine；And
One external screw thread, the external screw thread are arranged on the main body bar, and the external screw thread has an effective length, the electricity
The working unit stroke of machine device is directly proportional to the externally threaded effective length, and the range of the effective length is in 80-90mm.
Preferably, the range of the effective length is in 80-85mm.
Preferably, the range of the effective length is in 85-90mm.
By using above technical solution, since the externally threaded length of the main body bar is in 80-90mm, so that
The utility model has the beneficial effects that: improving the precision of assembly, increase the working unit stroke range of the electric machine, and
And improve the performance of motor.
By the understanding to subsequent description and attached drawing, the further purpose of the utility model and advantage will be able to abundant body
It is existing.
The these and other objects of the utility model, feature and advantage, by following detailed descriptions, attached drawing and right are wanted
It acquires to fully demonstrate.
Detailed description of the invention
Fig. 1 is the overall schematic of high-precision overlength threaded lead screw according to the present utility model.
Specific embodiment
It is described below for disclosing the utility model so that those skilled in the art can be realized the utility model.It retouches below
Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.It is retouched following
The basic principle of the utility model defined in stating can be applied to other embodiments, deformation scheme, improvement project, etc. Tongfangs
The other technologies scheme of case and the spirit and scope without departing from the utility model.
It will be understood by those skilled in the art that in the exposure of the utility model, term " longitudinal direction ", " transverse direction ", "upper",
The orientation or position of the instructions such as "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside"
Relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing the present invention and simplifying the description, and
It is not that the device of indication or suggestion meaning or element must have a particular orientation, be constructed and operated in a specific orientation, therefore
Above-mentioned term should not be understood as limiting the present invention.
It is understood that term " one " is interpreted as " at least one " or " one or more ", i.e., in one embodiment,
The quantity of one element can be one, and in a further embodiment, the quantity of the element can be it is multiple, term " one " is no
It can be interpreted as the limitation to quantity.
As shown in Figure 1, the utility model provides a kind of high-precision overlength threaded lead screw, the high-precision overlength screw thread
Driving screw includes a main body bar 10, and the high-precision overlength threaded lead screw is applied in an electric machine, when the main body bar
10 are assembled in the electric machine and are, the working unit stroke of the electric machine increases.
Further, the main body bar 10 is fitted to single servo motor, and the operation that the electric machine can be completed needs
It asks.The side of the main body bar 10 is provided with an external screw thread 11, and the effective length of the external screw thread 11 is 80-90mm.Institute simultaneously
The accuracy of thread for stating external screw thread 11 is higher, so that the external screw thread 11 can be improved the precision of assembly.
When the high-precision overlength threaded lead screw is arranged in the electric machine, the stroke model of the electric machine
Expansion is enclosed, and improves the performance of motor.In other words, the working unit stroke of the electric machine with it is described externally threaded
Effective length is directly proportional.
It is understood that the effective length of the external screw thread 11 can also be in 80-85mm, or in 85-90mm.
It should be understood by those skilled in the art that foregoing description and the embodiments of the present invention shown in the drawings are only used as
It illustrates and is not intended to limit the utility model.The purpose of this utility model completely and effectively realizes.The function of the utility model
Energy and structural principle show and illustrate in embodiment, under without departing from the principle, the embodiments of the present invention
Can there are any deformation or modification.
