Description

Leather cup quick press mounting device
Technical field
The present invention relates to a kind of assembling device, is the device that workpiece is carried out to leather cup quick press mounting specifically, is particularly useful for the leather cup assembling work of automobile braking master cylinder piston.
Background technology
As everyone knows, in mechanical manufacturing field, conventionally all need to use leather cup on the piston of compressing mechanism, it makes piston to be and to be tightly connected with other workpiece, thereby can improve the operating efficiency of compressing mechanism.In automobile manufacture industry, automobile brake is with also needing to assemble leather cup on the piston of master cylinder.At present, the assembling work of leather cup mainly contains two kinds of modes: one is hand assembled, be that operating personnel utilizes pliers that leather cup is strutted, and then be enclosed within on the piston of automobile braking master cylinder, this mode is owing to there is no special assembly tool, and its operation is more difficult, and operating efficiency is low, and easily cause the damage of leather cup, difficult quality guarantee; Another kind is to adopt mo(u)ldenpress assembling, press is provided power and is connected with pressure head by cylinder, by pressure head, leather cup is strutted, magnetic switch is housed on cylinder, receive after signal, sending instruction makes cylinder promote pressure head by given line, leather cup is pressed into desired location from of automobile braking master cylinder piston, this assembling mode can not cause the damage of leather cup, but complicated structure, equipment must supportingly have the electric control gears such as cylinder, magnetic switch, indenter device, PLC, and care and maintenance is difficulty comparatively, and input and use cost are relatively high.
Summary of the invention
The present invention requires the problem solving to be to provide a kind of leather cup quick press mounting device, adopts this device, leather cup assembling work that can Rapid Implementation automobile braking master cylinder piston, and this apparatus structure is simple, and cost is lower.
For addressing the above problem, take following scheme:
The feature of leather cup quick press mounting device of the present invention is to comprise base, is fixed with column on base, and there is pressure handle column upper end by chain connection.One side of described column is fixed with support, and this support is positioned at the swinging plane of pressure handle.On described support, there is vertical depression bar cover, in depression bar cover, have depression bar, the upper end of depression bar is connected with described pressure handle by hinge, and the lower end of depression bar is fixed with pressure head, on pressure head, be connected with multiple paws that stretch out downwards by pin-and-hole and pin, paw is circumferentially evenly arranged along the level of pressure head.The upper outside of described paw all has horizontal groove, all cannelures of an interruption of the groove of paw composition, and cannelure inner sleeve has O shape circle.Under described pressure head, on the base of correspondence, there is locating piece, on locating piece, have the deep hole of vertical layout and upper end open.On described locating piece, there is guide cone, between guide cone and locating piece, be movable and coordinate, and the outer upper end without leave of guide cone constantly expands to lower end.There is blind hole the bottom center position of described guide cone.
Further improvement of the present invention scheme is to have buffer bar on described pressure head, the short cylindrical that the upper end of buffer bar has one to connect with one heart, and the diameter of short cylindrical is greater than the diameter of buffer bar.The center position of described depression bar lower end has deep hole, and the diameter of this deep hole equals the diameter of described short cylindrical, and short cylindrical is positioned at this deep hole.The center position of described pressure head has through hole, and the diameter of this through hole equals the diameter of described buffer bar, and buffer bar extends downwards from this through hole.Between the end face of the upper surface of described short cylindrical and depression bar deep hole, there is Compress Spring.Utilize this buffer bar to coordinate with pressure head, in the time that workpiece enforcement leather cup is press-fited to operation, in the time that pressure head drops to buffer bar tip and contacts with guide cone top with depression bar, the Compress Spring at buffer bar top can produce cushion effect, thereby avoids the paw on pressure head to damage guide cone or workpiece.
Further improvement project of the present invention is that described depression bar bottom is fixed with spring housing near the position of pressure head, and the external diameter of spring housing is greater than the internal diameter of depression bar cover; On described support, have the extension spring of vertical layout, the upper end of extension spring is fixed on support, and the lower end of extension spring is fixed on described spring housing.Utilize this Compress Spring can make this device press-fit after operation completing leather cup, without manual operation, can make depression bar automatically reset.
Take such scheme, have the following advantages:
On base due to leather cup quick press mounting device of the present invention, there is column, there is pressure handle column upper end by chain connection, there is depression bar the below of pressure handle by chain connection, depression bar carries out Horizontal limiting by the support being connected with column, and there is pressure head depression bar lower end, on pressure head, there is paw, under pressure head, on the base of correspondence, have locating piece, on location is fast, has with it and be the movable guide cone coordinating.Using this device to carry out leather cup while press-fiting to automobile braking master cylinder piston, insert in the deep hole of locating piece one end of first piston being grown; Guide cone is covered on the shorter one end of piston, now, the opening of guide cone bottom surface blind hole just in time matches with the annular convex rib of leather cup stopper slot one side on this piston again; Then, leather cup to be assembled is enclosed within to the upper end of guide cone; Afterwards, manually pressure handle is pressed down, make it drive depression bar, pressure head and paw to decline simultaneously, paw promotes leather cup from leather cup upside and declines, until leather cup is pressed in the leather cup stopper slot of piston; Finally, lift pressure handle, remove after guide cone, automobile braking master cylinder piston is taken out.Whole operation process is very simple, can not cause damage to leather cup.And the structure of this device is also very simple, care and maintenance is very easy to, and its input and use cost are relatively low.
