Mainly it is to provide tensioning wheel installation function and provides auxiliary for the tool of installation.There is good extension feature, steel in view of steel
Axis forms stretching wheel assembly using riveting method.
The molding mode of current steel axis is riveted by a cold-heading part (steel shaft) and a stamping parts (gasket), system
Make at high cost, weight itself is big.And the forming force last at riveting of current steel axis can reach as many as 8000lb, need to adopt
It is produced with 40K equipment, causes to process cost height.
In view of the above shortcomings, the designer is actively subject to research and innovation, to found a kind of aluminum axle bolt molding
Formula attachment stretcher makes it with more the utility value in industry.
Utility model content
In order to solve the above technical problems, the purpose of the utility model patent is to provide a kind of aluminum axle bolt formation type attachment
Stretcher realizes that part material cost and production and operation cost reduce, improves the competitiveness of product in market.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of aluminum axle bolt formation type attachment stretcher, including belt wheel, aluminum pivot, spring, working arm and pedestal, band
Wheel is fixed on pedestal, is internally provided with bearing, and rotate synchronously and be arranged with belt wheel, is offered peace on the axis of pedestal
Hole is filled, on one end of aluminum pivot is plugged in the mounting hole of pedestal, and it is parallel with the top of pedestal, the other end passes through bolt
It is mutually fixed with mounting bracket, working arm, setting parallel with the bottom of working arm is equipped with by spring pocket on aluminum pivot.
The end of spring is fixed on the base by spring base as a further improvement of the utility model,.
Axle sleeve is provided between aluminum pivot and working arm as a further improvement of the utility model, and is also sleeved on
On aluminum pivot.
According to the above aspect of the present invention, the utility model at least has the following advantages:
The utility model provides a kind of aluminum axle bolt formation type attachment stretcher, from molding mode for, aluminum axis
Bolt formation type manufacturing cost will will reduce half, and weight equally reduces half；For in terms of the equipment investment, aluminum axis spiral shell
Bolt molding then only needs tightening device to produce, and tightening device can save half cost compared to 40K equipment.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
