Description
Technical field
This utility model belongs to go back to middle device technique field, relates in particular to a kind of return to neutral mechanism automatically.
Background technology
In returning, device is requisite part in machinery industry.In prior art, polyaxial from return to neutral mechanism by following
Several parts form: return spring A9, regulation bolt 10, return spring B11, link A12, return spring C13, return spring
D14, link B15, support A16, support B17(are as shown in Figure 2).This mechanism uses two groups of return springs to provide to control crank
Hui Zhongli, return spring A9 and return spring B11 is provided for support A16 from Hui Zhongli, return spring C13 and return spring D14
Hui Zhongli is provided, it is possible to be controlled by regulation bolt 10 spring force for support B17.
The major defect of this structure is as follows: 1) need just to be provided that the most axial Hui Zhongli by 2 groups of springs so that machine
The spatial volume that structure occupies is big；2) due to Position Design in not having back, during polyaxial manipulation so that during control crank, inertia causes
Product location in returning is unreliable；3) complicated structure, number of parts is many, causes product weight to reduce.
Summary of the invention
The purpose of this utility model be to overcome disadvantages mentioned above and provide a kind of compact conformation, easy to operate, portable can
Lean on, automatic return to neutral mechanism that precision is higher.
This utility model purpose and solve its technical problem underlying and realize by the following technical solutions:
Automatic return to neutral mechanism of the present utility model, including installing panel, positioning plate, central shaft, wherein: central shaft runs through
Being contained in installation middle panel, installing to connect on panel has positioning plate, and positioning plate top connects spring pedestal, spring pedestal
Internal equipped with spring, spring housing is contained in outside central shaft, and spring top, equipped with adjusting nut, is provided with fastening outside adjusting nut
Nut.
Above-mentioned automatic return to neutral mechanism, wherein: spring pedestal and positioning plate use sphere to match, and positioning plate is recessed ball
Face, spring pedestal is convex spherical.
Above-mentioned automatic return to neutral mechanism, wherein: positioning plate is connected by screw between panel with installing.
Above-mentioned automatic return to neutral mechanism, wherein: equipped with adjusting washer (disk) on adjusting nut.
This utility model compared with the existing technology has clear advantage and beneficial effect.From above technical scheme,
In automatic return to neutral mechanism of the present utility model, installing to connect on panel has positioning plate, and positioning plate top connects to be had at the bottom of spring
Seat, equipped with spring inside spring pedestal, spring pedestal and positioning plate use sphere to match, and positioning plate is concave spherical surface, bullet
Spring base is convex spherical, location in being achieved back by two spheres；Spring top, equipped with adjusting nut, sets outside adjusting nut
It is equipped with fastening nut, equipped with adjusting washer (disk) on adjusting nut, adjusting nut and the quantity of adjusting washer (disk) can be passed through, regulation spring
Precompression, thus increase and reduce stick control power.This utility model realizes the man-machine efficacy of product requirement by a set of mechanism
Feel and certainly time middle function, passing through a spring in structure is polyaxial offer steering force and the restoring force handled of handle, reduction product
Product design space and product weight.In a word, this utility model compact conformation, easy to operate, portable reliable, precision is higher, be suitable for
Promoting the use of in automatically returning.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to according to the automatic return to neutral mechanism specific embodiment party that the utility model proposes
Formula, structure, feature and effect thereof, after describing in detail such as.
See Fig. 1, automatic return to neutral mechanism of the present utility model, including installing panel 2, positioning plate 1, central shaft 8, its
In: central shaft 8 runs through to be contained in be installed in the middle part of panel 2, and installing to connect on panel 2 has positioning plate 1, and positioning plate 1 top connects
Having spring pedestal 3, spring pedestal 3 is internal equipped with spring 4, and it is outside that spring 4 is sleeved on central shaft 8, and spring 4 top is equipped with regulation spiral shell
Female 5, adjusting nut 5 is outside is provided with fastening nut 7.Spring pedestal 3 and positioning plate 1 use sphere to match, positioning plate 1
For concave spherical surface, spring pedestal 3 is convex spherical.Positioning plate 1 is connected by screw between panel 2 with installing.On adjusting nut 5
Equipped with adjusting washer (disk) 6.
During use, panel 2 is installed and is used for product return to neutral mechanism is installed, by return to neutral mechanism by fastening nut and control stick hands
Handle is attached.When control crank, spring pedestal 3 compression spring 4, thus provide restoring force to handle and handle feel, and
The precompression of spring 4 can be regulated by adjusting nut 5 and adjusting washer (disk) 6, thus increase and reduce stick control power (range of accommodation
It is 10～20N).Spring pedestal 3 and positioning plate 1 use spherical design, positioning plate 1 to be concave spherical surface, and spring pedestal 3 is convex ball
Face, when operating mechanism returns middle, location in being carried out back by two spheres.
The above, be only preferred embodiment of the present utility model, not this utility model is made any in form
Restriction, any without departing from technical solutions of the utility model content, according to technical spirit of the present utility model to above example
Any simple modification, equivalent variations and the modification made, all still falls within the range of technical solutions of the utility model.
