Abstract
The utility model aims to provide a floating type pressure head assembly of a press-fitting press, which is capable of avoiding damaging a pressure head and a bush or steel sleeve during press-fitting. The floating type pressure head assembly of the press-fitting press, which is used for achieving the aim, comprises a pressure head holder and the pressure head and is characterized by also comprising an axial locating piece fixed on the pressure head holder, wherein the mounting end of the pressure head is provided with a shaft head and a shaft neck arranged at the inner end side of the shaft head, the shaft neck is located in an inner hole of the axial locating piece, the external diameter of the shaft neck is smaller than the internal diameter of the inner hole of the axial locating piece, the internal diameter of the inner hole of the axial locating piece is smaller than that external diameter of the shaft head, the shaft head is inserted to a counterbore of the pressure head holder, and the external diameter of the shaft head is smaller than the internal diameter of the counterbore so that the shaft head can move in the counterbore.
Description
Technical field
The utility model relates to and press-fits press, relates in particular to the pressure head component that press-fits press.
Background technology
When press-fiting part such as lining, steel bushing, workpiece is placed on locatees on the press frock, lining or steel bushing are placed in the locating hole, press the button to start and press-fit the press pressure head, lining or steel bushing are pressed in the workpiece.As depicted in figs. 1 and 2, the pressure head component that press-fits press is a stationary structure, and is higher for press pressure head, frock, workpiece locating hole and lining axiality and dimensional requirement.And the product parts size must exist tolerance variations; Common usefulness is matched in clearance between frock and the workpiece locating hole; Pressure head, frock, workpiece locating hole and lining axiality are bound to occur deviation when therefore press-fiting; If deviation has surpassed fault-tolerant scope, can cause pressure head and lining or steel bushing to damage when then press-fiting. Label 11,12,13 indicates pressure head, screw and pressing head seat respectively among Fig. 1, Fig. 2.
The utility model content
The purpose of the utility model is to provide a kind of press floating formula pressure head component that press-fits, and causes pressure head and lining or steel bushing to damage when avoiding press-fiting.
Press-fit press floating formula pressure head component for what realize said purpose; Comprise pressing head seat, pressure head, be characterized in, also comprise the axial location part that is fixed on the pressing head seat; The installation end of pressure head has axle journal distolateral in spindle nose and the spindle nose; Axle journal is arranged in the endoporus of axial location part, and the external diameter of axle journal is less than the internal diameter of axial location part endoporus, and the internal diameter of axial location part endoporus is less than the external diameter of spindle nose; Spindle nose is inserted in the counterbore of pressing head seat, the external diameter of spindle nose less than the internal diameter of counterbore so that spindle nose can be movable in counterbore.
Describedly press-fit press floating formula pressure head component, its further characteristics are between the end face of spindle nose and the bottom of counterbore plane bearing to be set.
Describedly press-fit press floating formula pressure head component, its further characteristics are, the axial location part is two semicircular ring parts, and two semicircular ring parts are separately fixed on the pressing head seat.
The utility model improves the back pressure head can translation in the horizontal plane of certain limit, and when pressure head contact steel bushing, the chamfering of pressure head and steel bushing is brought into play guide effect, can let pressure head move to the position coaxial with steel bushing automatically.Even when beginning to press-fit like this, the axiality of pressure head and steel bushing has deviation, can automatic straightening through floating type pressure head, guarantee to press-fit quality, and basic the elimination scrapped.At present, along with auto industry high speed development at home, auto parts and components press-fit product; Cost and quality requirement to product are also increasingly high; The pressure head structure of the utility model is simple, be prone to processing, easy to operate, and significantly reduced lining and workpiece is scrapped, and also reduced the frock manufacturing expense.

Fig. 2 is the existing exploded view that press-fits press floating formula pressure head component.
Fig. 3 is the stereogram that press-fits press floating formula pressure head component of the utility model embodiment.
Fig. 4 is the exploded view that press-fits press floating formula pressure head component of the utility model embodiment.
The specific embodiment
Like Fig. 3 and shown in Figure 4, press-fit press floating formula pressure head component and comprise pressing head seat 23, pressure head 21, axial location part 22 and plane bearing 25.The installation end of pressure head 21 has axle journal 210 and spindle nose 212, axial location part 22 be the internal diameter of 22, two semicircular ring 22 of two semicircular ring be greater than axle journal 210 external diameter but less than the external diameter of spindle nose 212.Spindle nose 212 is inserted in the counterbore 231 of pressing head seat 23, and between the bottom of spindle nose 212 and counterbore 231 plane bearing 25 is set.Axial location part 212 is fixed on the pressing head seat 21 through screw 24, and axle journal 210 is arranged in the endoporus of axial location part 212, so the axial location of axial location part 212 locking pressure heads 21.The external diameter of spindle nose 212 is less than the internal diameter of counterbore 231; Therefore spindle nose 212 can be movable in counterbore 231, on the other hand, between the bottom of the end face of spindle nose 212 and counterbore 231 plane bearing 25 is set; Assisting down of plane bearing 25; Pressure head 21 can translation in the sagittal plane, can compensate the deviation that pressure head when press-fiting, frock, workpiece locating hole and lining axiality are bound to occur whereby, thereby causes pressure head and lining or steel bushing to damage when avoiding press-fiting.
