Description
Technical field
The utility model is related to the field of strip of paper used for sealing mould, and in particular to a kind of positioner of strip of paper used for sealing mould.
Background technology
Refrigerator strip of paper used for sealing is integrally fixed to improve the component of sealing in refrigerator doors, and after refrigerator doors are closed, strip of paper used for sealing is in refrigerator
Compressed under casing and the pressure of refrigerator doors, so as to reach the effect for improving sealing.The raw material of strip of paper used for sealing are usually rubber, warp
Cross mould compressing.
If strip of paper used for sealing mould is typically on the pressing part for use bolt stem fixed punch press, and pressing part and strip of paper used for sealing mould it
Between set cushion block be adjusted with the position to strip of paper used for sealing mould, due to install strip of paper used for sealing mould when can not simultaneously all bolts are same
When tighten, therefore strip of paper used for sealing mould unbalance stress can be caused, after a long time use, strip of paper used for sealing mould often occurs that deflection or part connect
The phenomenon that connecting bolt loosens, so as to cause the reduction of machining accuracy.In addition, when installing strip of paper used for sealing mould, due to can not twist simultaneously
Tight bolt, when adjusting wherein a certain bolt, the stress of other bolts will also change therewith, therefore in order to ensure the power of each bolt
Equilibrium, to ensure installation accuracy, it is necessary to repeatedly adjust, so when causing its installation fee.
Utility model content
The purpose of this utility model is to provide a kind of positioner of the strip of paper used for sealing mould of fast changeable strip of paper used for sealing mould.
To reach above-mentioned purpose, base case of the present utility model is as follows：
The positioner of strip of paper used for sealing mould includes the chuck for offering centre bore and being installed on machine tool chief axis or work top
Pedestal, and it is installed on by blind rivet the pallet bearing above chuck pedestal；The upper end of the blind rivet is connected with pallet bearing, is drawn
The lower end of nail is arranged in the centre bore of chuck pedestal, and the lower end of blind rivet offers annular groove；It is provided with the chuck pedestal
Multiple hydraulic control units, hydraulic control unit includes the oil duct in chuck pedestal, the piston in oil duct, located at work
Stage clip one below plug, oil duct is connected with the centre bore of chuck pedestal, and piston side offers spherical groove, spherical groove and annular groove
Between be provided with locking ball.
Center of the hydraulic control unit along chuck pedestal is circumferentially uniformly distributed, and chuck base side wall is provided with and oil duct
It is additionally provided with and is connected with oil duct and from chuck pedestal upper surface and the positioning hole of ft connection on the oil inlet of connection, chuck pedestal,
Provided with the positioning mandril being pressed on pallet bearing in positioning hole.
The chuck pedestal and pallet bearing are provided with the faceted pebble being mutually matched, and the blind rivet passes through pallet bearing, and draws
Nail is threadedly coupled with pallet bearing, and the upper end end of blind rivet is provided with interior hexagonal.
The principle of the positioner of this programme strip of paper used for sealing mould is：
During work, first chuck pedestal is fixedly mounted on the pressing part of stamping machine, the oil inlet on chuck base side wall
It is connected, and pallet bearing is fixed on strip of paper used for sealing mould with the hydraulic system of lathe beforehand through screw or by welding.Change
During strip of paper used for sealing mould, another pallet bearing fixed with strip of paper used for sealing mould and chuck pedestal are coordinated, then from hydraulic system to hydraulic pressure
Injection hydraulic oil in control unit, with the pressure increase in oil duct, piston will overcome spring force to move down, now position
Steel ball will be extruded out of spherical groove, and be entered in annular groove, then locking ball is locked by blind rivet, and blind rivet is also by pallet branch
Seat pulls to chuck pedestal, then completes pallet bearing and the positioning of the axiality of chuck pedestal.In addition with the increasing of pressure in oil duct
Plus, positioning mandril will form uniform pressure on pallet bearing, so as to occur when preventing pallet bearing from being moved to chuck pedestal
Crooked phenomenon, to ensure the perpendicularity of pallet bearing and chuck pedestal.
After blind rivet is locked, because chuck pedestal and pallet bearing are provided with the faceted pebble being mutually matched, then pallet bearing is not
It can be rotated relative to chuck pedestal；Therefore blind rivet is screwed by inner hexagon spanner, can be adjacent to pallet bearing and chuck pedestal, from
And make pallet bearing and chuck pedestal be rigid contact, improve stability and precision that pallet bearing and chuck pedestal coordinate.
This programme produce beneficial effect be：
（One）Set center of multiple hydraulic control units along chuck pedestal to be circumferentially uniformly distributed, blind rivet can be enable to be determined
Position steel ball is more securely locked.
（Two）Because blind rivet is by after locked, the position relationship of blind rivet and chuck pedestal is just determined, and now positioning mandril pair
Pallet bearing has tension, so as to prevent the connection of chuck pedestal and pallet bearing from occurring loosening phenomenon；And due to positioning
Push rod can make pallet bearing uniform stressed, therefore can improve the perpendicularity of pallet bearing and chuck pedestal.
In summary, the device passes through hydraulic pressure unit and blind rivet and coordinated so that only by rotate blind rivet can Fast Installation,
And positioning precision is high；When having been fixed in advance with pallet bearing additionally, due to strip of paper used for sealing mould, therefore having changed strip of paper used for sealing mould, pass through pallet
The cooperation of bearing and chuck pedestal, fast changeable strip of paper used for sealing mould.
Preferred scheme one：As the further optimization to base case, stage clip two is provided with below the positioning mandril；When more
When changing strip of paper used for sealing mould, that is, stop providing after pressure into hydraulic control unit, stage clip two will produce pallet bearing outside push away
Power, so that dismounting pallet bearing is more convenient.
Preferred scheme two：As the further optimization to base case, the stage clip one is arranged in compression spring sleeve, compression spring sleeve
It is threaded on chuck pedestal, to cause installation, the dismounting of stage clip one more convenient.
Preferred scheme three：As the further optimization to base case, stop nut is arranged with outside the positioning mandril, is limited
Position nut is threadedly coupled in positioning hole and with chuck pedestal, and positioning mandril is provided with the limit coordinated with stop nut lower surface
The position shaft shoulder, the upper surface of stop nut is provided with interior hexagonal.In preferred scheme five, stop nut can be limited positioning mandril
Position so that the more compact structure of chuck pedestal, and stop nut is screwed by interior hexagonal, stop nut and pallet bearing can be prevented
Interfere.
