Description
Technical field
The utility model relates to mechanical position limitation technical fields, in particular to a kind of adaptive centering limiting device.
Background technique
Large scale equipment needs a kind of mechanical device and is limited after translation or revolution.Large scale equipment limiting device
Quantity generally all more than two, it is even more.When multiple limiting devices carry out mechanical position limitation to same equipment, if large size is set
There are face difference or the differential seat angles of any direction between standby multiple confined planes, then general mechanical position limitation cannot guarantee that large size is set
Standby in-placing precision.
It is therefore desirable to have one kind can offset face difference or the limiting device of differential seat angle adaptively limits.
Summary of the invention
The purpose of the utility model is to provide the adaptive centering limit dresses that one kind can offset face difference or differential seat angle
It sets.
To achieve the above object, adaptive centering limiting device designed by the utility model includes being fixed on apparatus body
On flange support, ball head, bottom case, cover board, snap-gauge under snap-gauge and spherical surface on spherical surface, one end of the ball head is fixed on institute
It states on flange support, the spheric end of the ball head snap-gauge and snap-gauge under the spherical surface on the spherical surface by rotationally clip
In the spherical hollow space that loose fit is formed, the spherical hollow space clamping of snap-gauge and snap-gauge tight fit formation under the spherical surface on the spherical surface
Snap-gauge under snap-gauge on the spherical surface and the spherical surface is encapsulated in interior by the spheric end of the ball head, the bottom case and the cover board
Portion, the outer end face of the cover board are and confined planes contact surface.
Preferably, one end of the ball head is the end of thread, is connected to by check washer, stop nut spiral
In threaded hole on the flange support.
Preferably, the guide pin being slightly oriented to is provided on the outer end face of the cover board, the guide pin (90)
Front end is small compared with rear end diameter.
Preferably, the cover board is mounted on the outer end face of the bottom case by removable fasteners.
The beneficial effects of the utility model are: the adaptive centering limiting device of the utility model is connect using the end face of cover board
Contact that confined planes adjust automatically angle, limit effect are deacclimatized in the relative motion of spherical surface snap-gauge and ball head inside when confined planes
Good, simple and compact for structure, positioning accuracy is high, and adaptivity ability is strong.
Detailed description of the invention
Fig. 1 is the explosive view of the adaptive centering limiting device of the preferred embodiment in the utility model.
Fig. 2 is the assembling stereogram of the adaptive centering limiting device in Fig. 1.
Fig. 3 is the partial perspective view using the equipment of the adaptive centering limiting device in Fig. 2.
Fig. 4 is the enlarged drawing of the part I in Fig. 3.
Each part numbers are as follows in figure: (wherein, the flange support 1, check washer 2, locking of adaptive centering limiting device 10
Nut 3, ball head 4, bottom case 5, cover board 6, snap-gauge 8, guide pin 9 under snap-gauge 7, spherical surface on spherical surface)；Apparatus body 20.
Specific embodiment
It is described in further detail below in conjunction with details of the drawings and specific embodiments to the utility model.
Please refer to Fig. 1 and Fig. 2, the adaptive centering limiting device 10 that the utility model is preferably implemented include flange support 1,
Check washer 2, stop nut 3, ball head 4, bottom case 5, cover board 6, snap-gauge 8 and guide pin 9 under snap-gauge 7, spherical surface on spherical surface.Bulb
The end of axis 4 is screw thread, can be screwed into 1 inside of flange support and be fastened by check washer 2 and stop nut 3.On spherical surface
Snap-gauge 8 is pre- next by ball head 4 under snap-gauge 7 and spherical surface, is encapsulated into bottom by the bolt fastening outside bottom case 5, then by cover board 6
Inside shell 5.Guide pin 9 is mounted on 6 outside of cover board, the thick guiding for limiting device.It is provided on the outer end face of cover board 6 and slightly leads
To guide pin 9, the front end of guide pin 90 is small compared with rear end diameter.
Fig. 3 and Fig. 4 are please referred to, two groups of adaptive centering limiting devices 10 are fixed on apparatus body 20, are realized certainly
Adapt to centering and limit.First flange support 1 is installed on apparatus body 20, and passes through 4 bolt fastenings.Again by ball head 4
Threaded end be screwed into the inside of flange support 1 and fastened by check washer 2 and stop nut 3 after, entirely adaptively look for
Positive limiting device 10, which is fixed to, to be set on apparatus body 20.Using snap-gauge 8 under snap-gauge 7 on spherical surface and spherical surface by the ball of ball head 4
Head point pre-tightens, and is encapsulated into inside bottom case 5 by cover board 6.Apparatus body 20 drives flange support 1 to move, when the end of cover board 6
When face contact is to confined planes, internal spherical surface snap-gauge (snap-gauge 8 under snap-gauge 7 and spherical surface on spherical surface) and ball head 4 can relative motion,
Deacclimatize the current location of confined planes, adjust automatically angle.After equipment is retracted, cover board 6 is taken down, then by 7 He of snap-gauge on spherical surface
Lock-screw under spherical surface between snap-gauge 8 fastens completely, and adaptive centering is completed.Adaptive centering limiting device 10 often makes in pairs
With limit effect can be more preferable.
The adaptive centering limiting device of the utility model is suitable for large-scale mobile apparatus post exercise mechanical position limitation, tool
Adaptive centering function, simple and compact for structure after standby contact, and positioning accuracy is high, and adaptivity ability is strong.
