Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model
Apply example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all
Belong to the range of the utility model protection.
Embodiment one
As shown in Figure 1 and shown in Fig. 2, float positioning device provided by the embodiment of the utility model includes mounting base 1, stop
Portion 5, floating axle 4, oscillating bearing 3, positioning pin 2 and cylinder 7, wherein mounting base 1 has along axial through-hole, and oscillating bearing 3 is pacified
In the through-hole inside mounting base 1, the outer ring of oscillating bearing 3 is fixedly connected with mounting base 1, and one end of floating axle 4, which passes through, closes
It is connect after the inner ring of bearings 3 with positioning pin 2, retainer 5 can extend into mounting base 1 and can stretch along the axial direction of mounting base 1
Contracting movement.When carrying out welding positioning, retainer 5 protrudes into mounting base 1 and pushes against floating axle 4, is limited floating axle 4
It cannot rotate and/or swing with the inner ring of oscillating bearing 3, so that positioning pin be fixed, guarantee positioning accuracy.When needing pickup
When, retainer 5 is shunk, and contact it not with floating axle 4, when retainer 5 does not apply any power to floating axle at this time, floating axle 4
Constraint is lost, floating axle 4 is able to drive positioning pin 2 and rotates and/or swing with the inner ring of oscillating bearing 3 at this time, in pickup process
In, positioning pin can be rotated and/or be swung automatically, reduced friction between the two, have according to stress condition difference
Conducive to exiting for positioning pin 2, and the abrasion to positioning pin 2 and workpiece can be reduced.
It is preferably carried out in mode some, as shown in figure 3, the full swing angle a of floating axle 4 is 5 ° -9 °, such as can
To be 5 °, 6 °, 7 °, 8 °, 9 °, it is preferable that the full swing angle a of floating axle 4 is 7 °.
It should be noted that after the angle of oscillation of floating axle 4 refers to swing, the axis of floating axle 4 and the outer ring of oscillating bearing 3
Axis angle, floating axle 3 can swing to either direction.
It is shown referring to figs. 2 and 3 in order to further increase the positioning accuracy of positioning pin 2, mode is preferably carried out some
In, being equipped in one end (one end contacted with retainer 5) of floating axle 4 is in horn-like guiding recess portion, in one end of retainer 5
(one end being in contact with floating axle 4) is equipped with the fillet to match with guiding recess portion, when the two is in contact, is conducive to correcting side
To.
It is preferably carried out in mode in other, the annular protrusion of limitation retainer 5 is equipped in mounting base 1, in this way,
Part other than annular protrusion can have opposite space (greater than the diameter of retainer) for reasonably arranging or accommodating other
The internal diameter of component, annular protrusion is matched with retainer 5, plays the role of preventing retainer 5 from swinging, for example, shrinking in retainer 5
When, it is at least a part of not exit annular protrusion, to floating axle 4 it is mobile when, limited by annular protrusion, protect it always
Shield is vertical, assists in 2 correcting of positioning pin, especially in the embodiment with guiding recess portion, effect is become apparent.
About retainer 5, a separate part can be, one end is similar with cylinder, hydraulic stem or electric putter etc. to be executed
