According to the technical solution of the utility model：A kind of elastic steel ball tensioning locating device, it is characterised in that：Including positioning
Seat, positioning seat have the pillar upwardly extended, and convex cylindrical surface is arranged lower block, support base and upper stopper successively from lower to upper, on
Block is fixed on by cover board limiting on positioning seat, and cover board is adjustable relative to the height of positioning seat；The company of lower block and support base
The place of connecing sets several first steel balls by retainer, and the junction of lower block and support base sets several second steel by retainer
Ball is provided with spring between the lower block and positioning seat.
As further improvement of the utility model, the lower end of the support base upper and lower ends and upper stopper, lower block
Upper end is arranged respectively to cone-shaped, and the first steel ball, the second steel ball are respectively cooperating with being set to corresponding cone-shaped position, and can be along diameter
To movement.
As further improvement of the utility model, the bottom surface of the lower block is provided with several counterbores, each described
Spring is both provided in counterbore, lower spring end is pressed on positioning seat, and spring upper end is held out against at the top of counterbore.
As further improvement of the utility model, the cover board is connected by screw with positioning seat.
The utility model has technical effect that：The utility model product structure is simple, reasonable, suitable for all kinds of workpiece bases
The centering in quasi- hole clamps, even if there are dimensional discrepancys in different batches location hole aperture（In the qualified margin of tolerance）Also it can realize accurate
Centering, repetitive positioning accuracy are high.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
In Fig. 1,2, including cover board 1, screw 2, upper stopper 3, the first steel ball 4, support base 5, retainer 6, the second steel ball 7,
Lower block 8, positioning seat 9, spring 10 etc..
As shown in Figure 1, 2, the utility model is a kind of elastic steel ball tensioning locating device, including positioning seat 9, positioning seat 9
With the pillar upwardly extended, convex cylindrical surface is arranged lower block 8, support base 5 and upper stopper 3 successively from lower to upper, and upper stopper 3 is logical
It crosses the limiting of cover board 1 to be fixed on positioning seat 9, cover board 1 is adjustable relative to the height of positioning seat 9；The company of lower block 8 and support base 5
The place of connecing sets several first steel balls 4 by retainer 6, and the junction of lower block 8 and support base 5 sets several the by retainer
Two steel balls 7 are provided with spring 10 between the lower block 8 and positioning seat 9.
The lower end of 5 upper and lower ends of support base and upper stopper 3, lower block 8 upper end be arranged respectively to cone-shaped, the first steel ball
4th, the second steel ball 7 is respectively cooperating with being set to corresponding cone-shaped position, and can move radially.
The bottom surface of lower block 8 is provided with several counterbores, and spring 10,10 lower end of spring are both provided in each counterbore
It is pressed on positioning seat 9,10 upper end of spring is held out against at the top of counterbore.
Cover board 1 is connected by screw 2 with positioning seat 9.
The course of work of the utility model is as follows：The utility model product structure advantages of simple, to part datum hole into
When row centering clamps, workpiece datum hole engagement sleeves are set on 7 outside of the first steel ball 4 and the second steel ball, when placing part, first
The screw 2 on cover board 1 is unclamped, then places part downwards, at this point, part inner wall fits in the first steel ball 4, on the second steel ball 7,
Part downlink, until both the first steel ball 4, second steel ball 7 radially no longer move, the first steel ball 4 or the second steel ball 7 are cut at this time
The diameter that face determines is i.e. identical with part benchmark bore dia, that is, determines position location.
