Description
Technical field
The utility model relates to a kind of rotating mechanism, is specially adapted to pallet.
Background technology
Pallet refers to the jig that in machining, mounted workpiece going along with is shifted by automatic conveying between each station, is a large amount of frock clamps that use of assembling line.The feature of pallet is that use amount is large with line body circulation circulation, in most cases also needs fixture to rotate by 360 degree, to adapt to the various complex rotation matching requirements of workpiece.Therefore, the rotating mechanism utilization rate of fixture is higher.As shown in Figure 1, in prior art, the design of rotating mechanism mainly adopts top nylon sheet 1, bottom 45 steel plates 2, and the center of nylon sheet 1 and steel plate 2 is connected by bearing 4, and puts one group of steel ball 3 in both centres, to realize the rotation of fixture.
But from service condition, also there is following problem in existing rotating mechanism: one, processing technology more complicated, and expense is higher, and ball in use easily falls.Two, fixture only contacts with rotating mechanism on concentric circles, and therefore wearing and tearing are larger, thereby cause service life shorter.
Utility model content
The technical problems to be solved in the utility model be for overcome rotating mechanism processing technology complexity of the prior art and service life short defect, provide a kind of structure more optimal rotating mechanism.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of rotating mechanism, comprise the fixture upper plate and the fixture lower plate that connect up and down, its feature is, align mutually in the center of the center of described fixture upper plate and described fixture lower plate, and be penetrated with central shaft, between described central shaft and described fixture upper plate, be provided with zanjon bearing, on described central shaft, be also arranged with plane bearing, and described plane bearing is folded between described fixture upper plate and described fixture lower plate, below described fixture upper plate, be positioned on the upper surface of described fixture lower plate some rolling members are installed.
Preferably, described rolling member is multi-directional ball.
Preferably, described multi-directional ball is evenly distributed on concentric circles.
Preferably, described multi-directional ball is evenly distributed on non-concentric circles.
Preferably, described multi-directional ball adopts fixture to be fixed on the upper surface of described fixture lower plate.
Positive progressive effect of the present utility model is: the utility model improves by the rotating mechanism to pallet, has increased stability and the durability of fixture, and this rotating mechanism part has all used standard component simultaneously.Manufacturing cost be can effectively save, type selecting and manufacture are more convenient to relate to.
Brief description of the drawings
Fig. 1 is the structural representation of rotating mechanism in prior art.
Fig. 2 is the structural representation of the preferred embodiment of the utility model rotating mechanism.
Detailed description of the invention
Provide preferred embodiment of the present utility model below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 2, the utility model discloses a kind of rotating mechanism, it comprises the fixture upper plate 5 and the fixture lower plate 6 that connect up and down, is alignd mutually in the center of fixture upper plate 5 and the center of fixture lower plate 6, and is penetrated with a central shaft 7.Between central shaft 7 and fixture upper plate 5, be provided with a zanjon bearing 8.In addition, on central shaft 7, be also arranged with a plane bearing 9, and plane bearing 9 is folded between fixture upper plate 5 and fixture lower plate 6.Below fixture upper plate 5, be positioned on the upper surface of fixture lower plate 6 some rolling members are installed.
Further, rolling member described in the present embodiment is preferably multi-directional ball 10.Multi-directional ball 10 can be evenly distributed on concentric circles, also can be evenly distributed on non-concentric circles.Multi-directional ball 10 adopts fixture to be fixed on the upper surface of described fixture lower plate.The multi-directional ball 10 here, owing to being standard component, is for example bolted in fixture lower plate by fixture, does not have the problem coming off.And, in the time that multi-directional ball 10 is uniformly distributed on non-concentric circles, can effectively reduce the wearing and tearing of fixture upper plate, thereby extend the service life of fixture upper plate.
In the present embodiment, the effect of plane bearing 9 is the weight of bearing fixture upper plate 5, and plays supplemental support effect by multi-directional ball 10, becomes rolling friction, to improve the wearability of fixture upper plate while making the rotation of fixture upper plate.In addition, zanjon bearing 8 plays the effect that fixture upper plate 5 is centered and rotated.In the time that described rotating mechanism is used in pallet, putting with line body of fixture lower plate 6 moved, and fixture upper plate 5 clamping workpieces can need to carry out the rotation of 360 degree according to process operations in the time of work.Zanjon bearing 8 rotates fixed center, the weight of plane bearing 9 support fixture upper plates 5 and workpiece, and planar friction is converted to rolling friction while fixture upper plate 5 being rotated together with multi-directional ball 10, thus reduce personnel labor intensity, improve service life.
In sum, the part of the utility model rotating mechanism has all used standard component, can effectively save manufacturing cost like this, has reduced processed complex, makes design selection and manufacture convenient, is applicable to the feature of streamline batch production.It has increased stability and the durability of fixture by the improvement of the rotating mechanism to fixture.
Although more than described detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these changes and amendment all fall into protection domain of the present utility model.
