As shown in Figure 2, Figure 3 and Figure 4, positioning device 1 of the present invention is used for a tinsel to be positioned on a component of machine, in the present embodiment, this component of machine is the wheel hub of an automobile clutch, and described tinsel is the circular dust cover of sealing described wheel hub one end.Positioning device 1 comprises columned main shaft 11, is positioned at the pressure head 12 of main shaft 11 ends, the stopper part 15 coaxial apart from pressure head 12 a distance and main shaft 11, and movable set is on main shaft and the setting sleeve 14 coaxial with main shaft.
The main shaft 11 of positioning device 1, pressure head 12 and stopper part 15 are integrally formed, and therefore in working process, they can guarantee to have a good coaxality and tolerance, precision problem when this also can guarantee dust cap location indirectly.The radial dimension of stopper part 15 is greater than the radial dimension of pressure head 12 and stopper part 15 apart from pressure head 12 certain distances, and when dust cap location is convenient in this design, pressure head 12 moves down.The magnetic element 13 that the lower surface of pressure head 12 is also concaved with receiving groove 120, one circles of a circle be contained in this receiving groove 120 and maintenance coaxial with main shaft 11.Certainly, as long as maintenance receiving groove and main shaft are coaxial, receiving groove also can be set to other shapes, such as square and Hexagon etc.The magnetic element 13 of outwards projection it is pointed out that magnetic element 13 can not stretch out the lower surface of pressure head 12, because can affect the pressing result of pressure head 12.
Setting sleeve 14 comprises circular roof 141, the sidewall 143 of the ring-type from roof 141 to downward-extension and surround the space, location 140 forming by roof 141 and sidewall 143.The central position of roof 141 forms a manhole 142, and its slightly larger in diameter is in the radial dimension of main shaft 11, and therefore, main shaft 11 can and move up and down with respect to setting sleeve 14 in the vertical directions through this through hole 142.The radial dimension in space 140, location is slightly larger than or equals the outside dimension of described stopper part 15, that is to say that both sizes are suitable, can guarantee like this coaxality of setting sleeve 14 and main shaft 11 and pressure head 12.Sidewall 143 is provided with continuous inclined wall 144 in the one end away from roof 141, and when dust cap is installed, this inclined wall 144 can be guided dust cap and be entered in space 140, location, and therefore, this inclined wall 144 also can be known as guide portion.
After the through hole 142 of setting sleeve 14 is sleeved on main shaft 11 through main shaft 11, pressure head 12 and stopper part 15 are contained in the space, location 140 in setting sleeve 14, and in the vertical direction, the lower surface of pressure head 12 has a segment distance apart from the guide portion 144 of setting sleeve 14.Like this, when dust cap enters space 140, location when interior by guide portion 144, attraction due to magnetic element 13, dust cap can move along the inwall of sidewall 143 a described segment distance, thereby allow dust cap be adjusted to better the position coaxial with main shaft 11, that is to say, dust cap is being pressed to before the wheel hub of automobile clutch, can reach a good location degree, this has facilitated follow-up pressing operation process of carrying out.
