Abstract
The utility model relates to a floating locating base which is characterized in that a base (6) is included, the lower end of a floating sleeve (3) is arranged in a mounting groove in the base (6), a pressing cover (4) is arranged on the base (6) at the upper end of the mounting groove, so that the lower end of the floating sleeve (3) is limited in the mounting groove, a steel ball (5) is arranged between the floating sleeve (3) and the base (6) in the mounting groove, in addition, the upper end of the floating sleeve (3) is hollow, one end of a telescopic locating column (1) extends into the upper end of the floating sleeve (3), a spring (2) is arranged in the floating sleeve (3), and the two ends of the spring are respectively connected with the telescopic locating column (1) and the floating sleeve (3). Trials show that after the floating locating base is used, the radial floating amount of the floating locating base is used for removing errors, and accordingly a workpiece is completely located on the locating base, and pressing pass rate is guaranteed.
Description
Technical field
The utility model relates to a kind of unsteady positioning seat.
Background technology
Positioning seat press-fits the location of a plurality of linings for automobile accessory frame welding assembly, because the steel bushing of subframe welds, majority is welded on a subframe by 4 above steel bushings, generally adopts stationary positioned seat location to press-fit.Because not eliminating the error between the subframe steel bushing, affected and press-fited quality.
The utility model content
The purpose of this utility model is to provide a kind of unsteady positioning seat, after this positioning seat that floats of use, can improve and press-fit quality.
A kind of unsteady positioning seat, its special feature is: comprise base, the lower end of floating bushing is installed in the mounting groove on this base, thereby gland also is installed on the base of this mounting groove upper end, the lower end of this floating bushing is limited in mounting groove, and steel ball also is installed between the floating bushing in mounting groove and base; The upper end hollow of floating bushing in addition, an end of a flexible locating dowel stretches in the upper end of this floating bushing, and in floating bushing, spring also is installed, and the two ends of this spring are connected with floating bushing with flexible locating dowel respectively.
Wherein in the lower end of floating bushing, be provided with step.
Thereby wherein on flexible locating dowel, having spring groove stretches into wherein for spring.
Wherein between the lower end of floating bushing and the mounting groove on base, leave gap.
Through probationary certificate, after adopting unsteady positioning seat of the present utility model, by utilizing the radial floating amount of the positioning seat that floats, eliminated error, thereby workpiece has been positioned on positioning seat completely, guaranteed to press-fit qualification rate.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is a kind of unsteady positioning seat, comprise base 6, the lower end of floating bushing 3 is installed in the mounting groove on this base 6, thereby on the base 6 of this mounting groove upper end, gland 4 also being installed is limited in the lower end of this floating bushing 3 in mounting groove, and steel ball 5 also is installed between the floating bushing 3 in mounting groove and base 6, the quantity of steel ball 5 can be determined as required, but at least should guarantee can steadily move between floating bushing 3 and base 6.The upper end hollow of floating bushing 3 in addition, an end of a flexible locating dowel 1 stretches in the upper end of this floating bushing 3, and in floating bushing 3, spring 2 also is installed, and the two ends of this spring 2 are connected with floating bushing 3 with flexible locating dowel 1 respectively.
Wherein in the lower end of floating bushing 3, be provided with step, thereby and have spring groove stretch into wherein for spring 2 on flexible locating dowel 1.Leave gap between mounting groove on the lower end of floating bushing 3 and base 6 in addition.
Operation principle of the present utility model and using method are:
Operation principle: owing between the lower end of floating bushing 3 and the mounting groove on base 6, leaving gap, floating bushing 3 can move arbitrarily in certain limit on horizontal plane by steel ball 5, press-fit the mismachining tolerance between lining thereby eliminate two quilts, guaranteed the location between lining.
Using method: unsteady positioning seat of the present utility model is general to be supported the use with a stationary positioned seat, and stationary positioned seat radial direction can not be floated.When press-fiting two linings, what a liner sleeve the stationary positioned seat fixes, and due between another liner sleeve and it, the welding error is arranged, if all adopt the stationary positioned seat, one of them liner sleeve, because the welding error is arranged, just can't be inserted on positioning seat fully.Adopt now a stationary positioned seat and a unsteady positioning seat, radial floating amount by the positioning seat that floats, can effectively solve the welding error, liner sleeve is fixed on flexible locating dowel 1, then lining is arranged on to flexible locating dowel 1 top, press-fit lining by pressure head, flexible locating dowel 1 and spring 2 shrink, and lining is pressed in sleeve.
Claims (4)
1. a unsteady positioning seat, it is characterized in that: comprise base (6), the lower end of floating bushing (3) is installed in the mounting groove on this base (6), gland (4) also is installed on the base (6) of this mounting groove upper end thus the lower end of this floating bushing (3) is limited in mounting groove, and steel ball (5) also is installed between the floating bushing in mounting groove (3) and base (6); The upper end hollow of floating bushing (3) in addition, one end of one flexible locating dowel (1) stretches in the upper end of this floating bushing (3), and spring (2) also is installed in floating bushing (3), and the two ends of this spring (2) are connected with floating bushing (3) with flexible locating dowel (1) respectively.
2. a kind of unsteady positioning seat as claimed in claim 1, is characterized in that: wherein in the lower end of floating bushing (3), be provided with step.
3. a kind of unsteady positioning seat as claimed in claim 1 or 2 is characterized in that: wherein in flexible locating dowel (1) thus on have spring groove and stretch into wherein for spring (2).
4. a kind of unsteady positioning seat as claimed in claim 1 or 2, is characterized in that: wherein between the mounting groove on the lower end of floating bushing (3) and base (6), leave gap.
