Detailed Description
For better understanding of the present invention, the technical solution of the present invention will be further described below with reference to the following embodiments and accompanying drawings.
Referring to fig. 1 and 6, a coaxial centering device comprises a through centering disc 2 fixedly mounted on a fixed mounting member 1, a rotating disc 3 sleeved on the fixed disc 2 and rotating, and a driving mechanism for driving the rotating disc 3 to rotate in a reciprocating manner (the driving mechanism is a cylinder 4, two ends of the cylinder 4 are respectively hinged with the fixed mounting member 1 and the rotating disc 3, and two cylinders 4 are respectively arranged at the top and the bottom of the rotating disc 3); evenly be equipped with three at least swing centering rod 5 on the rolling disc 3 (form central symmetry structure, the symmetry point is the centre of a circle of price fixing 2), the tangent line circle 14 that all swing centering rod 5 formed is concentric with price fixing 2, be equipped with on the price fixing 2 with swing centering rod 5 assorted rotation uide bushing 6, the one end and the rolling disc 3 of swing centering rod 5 rotate to be connected (swing centering rod 5 is connected with rolling disc 3 through bulb type joint bearing 7), swing centering rod 5 still passes corresponding rotation uide bushing 6.
As shown in fig. 2, 3 and 4, the fixing and mounting member 1 is provided with a circular hole, the fixed plate 2 is a flange plate, the flange plate and the circular hole are concentrically arranged, and the flange plate is connected with the fixing and mounting member 1 through a bolt. An adjusting washer 8 is arranged between the flange plate and the fixed mounting part 1. The rotating disc 3 is positioned between the flange plate and the fixed mounting part 1, and lining plates 9 are arranged between the rotating disc 3 and the flange plate and between the rotating disc 3 and the fixed mounting part 1.
As shown in fig. 4, the rotation guide sleeve 6 includes an oilless bushing 10 (the swing centering rod 5 is inserted in the oilless bushing 10), a rotation shaft 11 is arranged outside the oilless bushing 10, and the rotation shaft 11 is connected with the fixed plate 2 through a bearing (preferably, a deep groove ball bearing 12) (the end of the rotation shaft 11 is further provided with a lock nut 13).
As shown in fig. 1 and 6, the number of the swinging centering rods 5 is six. If too many swing centering bars 5 are complicated in structure, a failure is likely to occur, the rotating disc 3 may not rotate smoothly, and if too few swing centering bars 5 are insufficient in shaft restriction, the best centering effect cannot be achieved.
The utility model discloses an action process and principle: when one cylinder extends out and the other cylinder retracts, the cylinders drive the rotating disc 3 to rotate, the six swinging centering rods 5 are simultaneously opened outwards under the action of the rotating disc 3, the fixed disc 2 and the rotating guide sleeve 6, and the diameter of a tangent circle 14 formed by the six swinging centering rods 5 is increased; inserting a shaft to be centered into a central hole of the fixed disc 2; when two cylinders do reverse action, the cylinders drive the rotating disc 3 to rotate, the six swinging centering rods 5 simultaneously contract inwards under the action of the rotating disc 3, the fixed disc 2 and the rotating guide sleeve 6, the diameter of a tangent circle 14 formed by the six swinging centering rods 5 is reduced, the diameter of the tangent circle is still concentric with the fixed disc 2, and the shaft is centered by the contracted swinging centering rods 5. And the device can be adapted to rod pieces with different diameters by adjusting the size of the tangent circle.
The above description is only an example of the present invention, and certainly, the scope of the present invention should not be limited thereto, and therefore, the present invention is not limited to the above description.
