Background technology
In Robot Design field now, the tire of most wheeled mobile robot is all directly fixed on robot body power take-off shaft by screw etc.Although this kind of connection mode structure is simple, later maintenance is very difficult, and when robot is applied out of doors, tire consumption is serious, and tire changing is very complicated, needs the device of special changing of tire; This will have a strong impact on the normal operation and maintenance of robot.
Utility model content
The purpose of this utility model is exactly to overcome the above problems, provide a kind of mobile robot's expansion sleeve type quick detach tire construction, the tire of the upper wearing and tearing of this structure energy quick-replaceable mobile robot, improves robot localization precision, in scientific research and application on the spot, all have practical value.
To achieve these goals, the utility model adopts following technical scheme:
A kind of mobile robot's expansion sleeve type quick detach tire construction, comprising: one-level expansion set, secondary expansion set, tire expansion set adapter shaft, tire, quick detach pull bar and pull bar preloading spring;
One end of described one-level expansion set is connected with tire expansion set adapter shaft, and the other end is connected with power take-off shaft; Described tire is connected with tire expansion set adapter shaft by secondary expansion set, described power take-off shaft, one-level expansion set, tire expansion set adapter shaft are sequentially connected in series vertically by quick detach pull bar, in the tapped bore of described quick detach pull bar one end precession power take-off shaft, between described power take-off shaft and tire expansion set adapter shaft, there is pull bar preloading spring.
Described quick detach pull bar comprises: cam, cam adapter shaft, pull bar and cam pad; Described cam is connected with pull bar one end by cam adapter shaft, and the described pull bar other end is provided with screw thread, can coordinate with the axle being threaded hole; The one side of described cam pad is plane, and another side is the concave surface matched with cam.
The utility model beneficial effect:
1, the utility model carrys out quick-detachment tire by pulling out quick detach pull bar; By regulating the predetermincd tension of quick detach pull bar, reach the effect regulating expansion set predetermincd tension, thus reach the effect regulating tire torque.
2, the utility model main parts size can select existing product on the market, and as Z1, Z2 type expansion set, interchangeability is good, convenient later maintenance.
3. the expansion set selected of the utility model is with centering property, can centering core wheel voluntarily, improves tire positioning precision, when the high precision apparatus such as robot are applied, effectively can ensure running precision, prevent the problems such as sideslip, in industries such as robots, there is high practical value.
4. the expansion set that the utility model is selected will lose anastomosis when overloading, and can preserve from by proterctive equipment.

Fig. 3 is the utility model quick detach Tiebar structure schematic diagram;
Wherein, 1, power take-off shaft, 2, tire, 3, tire expansion set adapter shaft, 4, Z2 type expansion set, 5, Z1 type expansion set, 6, quick detach pull bar, 7, pull bar preloading spring; A1, pull bar, A2, cam adapter shaft, A3, cam, A4, cam pad.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As depicted in figs. 1 and 2, wheel mechanism for tire carrys out transmitting torque by two-stage expansion set to a kind of mobile robot's expansion sleeve type quick detach tire construction between tire 2 and power take-off shaft 1, and two-stage expansion set type is different.Finally, control expansion set predetermincd tension by quick detach pull bar 6, and realize the quick-replaceable object of wheel mechanism for tire by pulling out quick detach pull bar 6.
Specifically, tire 2 and tire expansion set adapter shaft 3 are linked together by a kind of Z2 type expansion set 4, then tire expansion set adapter shaft 3 and power take-off shaft 1 are linked together by a kind of Z1 type expansion set 5, after several parts connect, are tightened up by several parts by quick detach pull bar 6.
First tire 2 is connected on tire expansion set adapter shaft 3 by 4 expansion set Z2, power take-off shaft 1 and tire expansion set adapter shaft 3 are coupled together by 5 expansion set Z1, there is spring 7 between power take-off shaft 1 and tire expansion set adapter shaft 3, while predetermincd tension is provided, conveniently exit tire expansion set adapter shaft 3.6 one, quick detach pull bar is tightened on the tapped bore of power take-off shaft 1 one end, being screwed into the degree of depth, controlling predetermincd tension by regulating.Pull bar preloading spring 7 can effectively prevent from quick detach pull bar 6 from producing loosening, and cam closed finally by quick detach pull bar 6, produces axial location.By above cooperation, the moment of torsion passed over from power take-off shaft 1 is delivered to tire expansion set adapter shaft 3 by 5 expansion set Z1, is then delivered on tire 2 by 4 expansion set Z2.Expansion set is divided into two-layer, inside and outside two-layer be all the sleeve having certain taper, by inside and outside two-layer mutual extruding, two-layerly to fit together inside and outside, thus transmitting torque.
Be illustrated in figure 3 quick detach pull bar 6 structural representation, cam A3 is connected with pull bar A1 by cam adapter shaft A2, and cam pad A4 one side is plane, and another side is the concave surface matched with cam A3.When the handle of rotating cam A3 makes cam convex surface match with cam pad A4 concave surface, make cam pad A4 plane tightly compacting on agent surface, play fixing, loosen dynamic object.
Quick detach pull bar 6 is a cam lock holding mechanism, and its pull bar A1 end has screw thread, can be fastened on and be threaded on the axle in hole, cam A3, while be slack list, is pilled-in selvedge, when cam A3 is pressed down by handle, pilled-in selvedge is tightly fitted on pull bar A1, makes front and back two parts tightly compacting of transmission.
The utility model can convenient replacing tire by quick detach pull bar, convenient, reliably.The expansion set model selected is many, A wide selection of colours and designs, and different model expansion set can be arranged in pairs or groups different loads tire, and practicality is good, and interchangeability is good, convenient design.
The expansion set selected of the utility model, can centering core wheel voluntarily with centering property, improves tire positioning precision, when the high precision apparatus such as robot are applied, effectively can ensure running precision, prevent the problems such as sideslip, in industries such as robots, there is high practical value.
The expansion set that the utility model is selected will lose the effect of connection when overloading, and can preserve from by proterctive equipment.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
