Description
Technical field
This utility model belongs to component of machine manufacture field, particularly relates to assembling of molectron.
Background technology
Product described in this utility model is a kind of combination parts for power drill, and these parts include by upper gear
Tripod that sheet, lower stop piece and bearing pin connect and compose and the gear being sleeved on bearing pin, as it is shown in figure 1, customer requirement product
Gear in molectron can rotate freely, and can not teetertotter again, and the requirement to product is higher.Prior art is by each for product zero
Parts directly assemble, and are not easily controlled uniformly owing to assembling the pressure of machine, cause great majority to assemble product middle gear and are not easy to turn
Moving or teetertotter, causing product percent defective the highest, close to 50%, production cost increases, inefficiency.
Summary of the invention
For the defect overcoming prior art to exist, this utility model provides a kind of simple in construction and using effect is significant
Fitting device.
A kind of fitting device improving tripod and gear assemblies assembly precision, be characterized in including hollow circular cylinder and
Being placed in the base of hollow circular cylinder inside bottom, described base is made up of upper plate, lower shoe and elastomeric element, described lower shoe
Upper surface is at least uniformly provided with three boss, and described upper plate lower surface is at least uniformly provided with three grooves and described boss pair
Should, boss is arranged with elastomeric element and stretches in groove, hollow circular cylinder, upper plate, the central axes of lower shoe, its
Coordinate the height of composition higher than Product processing height 3-5mm.
Above-mentioned elastomeric element is butterfly spring or helical spring, and the ram pressures according to assembling machine calculates, and selects concrete butterfly
Spring or helical spring.
It is contemplated that the Reusability of this fitting device, friction between fitting device and the briquetting assembling machine, can be produced,
Thus causing abrasion, the upper surface surface-coated of described hollow circular cylinder has one layer of wearing layer, substantially increases fitting device
Service life.
The internal diameter of above-mentioned hollow circular cylinder and a diameter of matched in clearance being more than zero of circle product external, it is simple to product is put into or taken
Go out.
For ensureing machining accuracy, product component upper surface uniform force, it is desirable to described hollow circular cylinder top surface plane degree,
Lower surface flatness is respectively less than 0.1mm.
Between above-mentioned upper plate, lower shoe, it is provided with connection spring, effectively fixes upper plate and lower shoe.
Compared with prior art, the beneficial effects of the utility model are:
1) this utility model uses hollow circular cylinder, product component upper surface to keep with the hollow circular cylinder upper surface depth of parallelism
Unanimously, when using the machine that assembles to compress downwards, product component upper surface uniform force, therefore bearing pin, upper stop piece, lower stop piece and gear
Fitness uniform, it is ensured that gear rotating freely on bearing pin, and will not teetertottering, improve tripod and gear combination
Part assembly precision；
2) this utility model uses elastic base, and product component can be placed on base, after the machine that assembles compresses, and product
Assembly is upspring, and takes out product component, substantially increases work efficiency；
3) this utility model simple in construction, easy to operate, considerably improve conforming product rate, reduce production cost.
Accompanying drawing explanation
Below in conjunction with concrete accompanying drawing, this utility model is further illustrated.
Fig. 1 is prior art products structural representation；
Fig. 2 is that this utility model fitting device coordinates assembling product figure；
Fig. 3 is structural representation of the present utility model；

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further illustrated.
As shown in Figures 2 to 4, a kind of fitting device 10 improving tripod and gear assemblies assembly precision, including hollow
Cylinder 11 and be placed in the base of hollow circular cylinder inside bottom, described base is by upper plate 12, lower shoe 14 and elastomeric element
13 are constituted, and described lower shoe upper surface is at least uniformly provided with three boss 141, and described upper plate lower surface is at least uniformly provided with three
Individual groove 121 is corresponding with described boss, boss is arranged with elastomeric element and stretches in groove, hollow circular cylinder, upper plate, under
The central axes of base plate, it coordinates the height of composition higher than product 20 working height 3-5mm.
During work, first by bearing pin frock, three bearing pins are assembled on a baffle plate, then three gears are through three pins
On axle, then another baffle plate is installed on three bearing pins, treat that die pressing product is placed on base, by hollow circuit cylinder assemble
Body is enclosed within product, and after the switch by subordinate machine, the pressure head assembling machine moves down, table on fitting device upper surface and product
Face simultaneously uniform stressed, it is ensured that do not rock during product stress, overhead gage, lower baffle plate and bearing pin be stressed after closely cooperating
In same level, and uniform force, so that pinion rotation does not teetertotters.
In the present embodiment, described elastomeric element 13 is butterfly spring or helical spring, according to the ram pressures meter assembling machine
Calculate, select concrete butterfly spring or helical spring.
It is contemplated that the Reusability of this fitting device 10, can produce between fitting device and the briquetting assembling machine and rub
Wiping, thus cause abrasion, the end face surface of described hollow circular cylinder 11 is coated with one layer of wearing layer 111, substantially increases work
The service life of assembling device.
The internal diameter of described hollow circular cylinder 11 and product 20 outside diameter are the matched in clearance more than zero, it is simple to product is put
Enter or take out.
For ensureing machining accuracy, product 20 assembly upper surface uniform force, it is desirable to described hollow circular cylinder 11 upper surface is put down
Face degree, lower surface flatness are respectively less than 0.1mm.
Between described upper plate 12, lower shoe 14, it is provided with connection spring 15, effectively fixes upper plate and lower shoe.
Therefore, although fitting device simple in construction of the present utility model, but ensure that the group of tripod and gear well
