Description
Technical field
The utility model is related to Small Air-Cooled Gasoline Engine crankcase assembly field more particularly to crankcase synchronous press mounting axis
It holds and the field of oil sealing.
Background technology
In miniature gasoline engine crankcase assembling process, what pressing bearing and oil sealing typically carried out respectively, efficiency is low, dress
With unstable quality, Gasoline Engine performance is influenced.
Some esbablished corporations of the country mostly use automatic assembly line installation at present, although realizing mechanization mass production,
Because equipment investment is big, production trouble is changed, is not suitable with multi items, the application of small lot enterprise.As can a kind of compound assembly tool of invention,
Under the premise of not influencing assembling quality, production efficiency is high, changes production conveniently, and adapts to the simple work of small mount, multi items production
Tool is necessary.
Utility model content
The purpose of this utility model is high-quality a press fitting of design, small investment, efficient, replacement tooling is convenient, is adapted to
In multi items, the tool of small lot production.
To achieve the above object, using following technical scheme：
For Small Air-Cooled Gasoline Engine crankcase pressing bearing and the tool of outside framework oil seal, including die holder, dynamic model, guiding
Pressure head, top stem casing, return spring, fixing nut are arranged dynamic model on the die holder, return bullet are provided between dynamic model and die holder
The lower end of spring, return spring is connect with die holder, and the upper end of return spring is connect with dynamic model；The top stem casing is hollow rigid enclosure
Pipe, sequentially passes through dynamic model, die holder, fixing nut fixes top stem casing and die holder, top stem casing when not applying pressure straight down
Upper top be less than the upper top surface of dynamic model, top stem casing and dynamic model form die cavity；It is described to be oriented to the mandril that pressure head lower end is long cylinder,
Mandril can be inserted top stem casing and move up and down, be oriented to pressure head upper end end face it is more hollow than top stem casing end face it is big, limit be oriented to pressure
Head goes successively to top stem casing.
The utility model provides power source by pneumatic press, and primary press fitting can complete indentation work while bearing and oil sealing
Industry, efficient, replacement tooling conveniently, are adapted to multi items, the tool of small lot production.
Description of the drawings
Fig. 1 is the utility model for the device embodiment of Small Air-Cooled Gasoline Engine crankcase pressing bearing and oil sealing
Structural schematic diagram.
Specific implementation mode
It is elaborated below in conjunction with the accompanying drawings to the utility model by embodiment, but this is not to the utility model
It limits.
As shown in Figure 1, in figure：1, die holder, 2, dynamic model, 3, be oriented to pressure head, 4, outside framework oil seal, 5, bearing, 6, top stem casing, 7,
Return spring, 8, fixing nut, 9, crankcase.
For Small Air-Cooled Gasoline Engine crankcase pressing bearing and the tool of outside framework oil seal, including die holder 1, dynamic model 2, lead
To pressure head 3, outside framework oil seal 4, bearing 5, top stem casing 6, return spring 7, fixing nut 8, dynamic model 2, dynamic model are set on the die holder 1
Return spring 7 is provided between 2 and die holder 1, the lower end of return spring 7 is connect with die holder 1, upper end and the dynamic model 2 of return spring 7
Connection；The top stem casing 6 is hollow rigid casing, sequentially passes through dynamic model 2, die holder 1 straight down, and fixing nut 8 will push up
Rod set 6 is fixed with die holder 1, and the upper top of top stem casing 6 is less than the upper top surface of dynamic model 2, top stem casing 7 and dynamic model 2 when not applying pressure
Form die cavity；Described to be oriented to the mandril that 3 lower end of pressure head is long cylinder, mandril can be inserted top stem casing 6 and move up and down, and be oriented to pressure head
The 3 upper end end face end face more hollow than top stem casing 6 is big, limits and is oriented to pressure head 3 and goes successively to top stem casing 6.
When work, first crankcase 9 is put on dynamic model 2, then bearing to be pressed into is positioned over top stem casing by center alignment
7 are formed by with dynamic model 2 in die cavity, then by oil-sealing sleeve to be pressed on the mandril for being oriented to 3 lower end of pressure head, will then be oriented to
The mandril of 4 lower end of pressure head is simultaneously inserted into top stem casing, and bearing can disposably be completed by starting forcing press to the application of pressure head 3 pressure is oriented to
5 with the assembling work of outside framework oil seal 4.
During being pressed into bearing 5 and outside framework oil seal 4, outside framework oil seal 4 imports 9 oil sealing of crankcase gear first, is then pressed
Enter, with being continuously increased for the stroke of a press, dynamic model 2 and then moves down, and bearing 5 is also forced into the bearing chamber of crankcase 9, assembly
Process is completed, and no pressure on pressure head 3 is oriented to, and then, dynamic model 2 resets under the effect of return spring 7.
Once press fitting can be completed to be pressed into operation while bearing and oil sealing the utility model, and production efficiency is high, changes production side
Just, and small mount, multi items production is adapted to.
Claims (1)
