By the pressure head device, automatic correcting of center positioning deviation and centering can be realized when shaft parts are subjected to matched press fitting, and press fitting force can be detected at the same time;and the pressure head device is high in press-fitting accuracy, stable in press-fitting force and capable of being widely applied to matched press fitting of the shaft parts.
Description
Technical field
The present invention relates to a kind of centralized positioning deviation press-fited for the Axial parts cooperation and automatically revise indenter device.
Background technology
Assembling is exactly by various parts, parts, component or assembly, and technical conditions in accordance with regulations and quality requirement connect the production process that is combined into complete product, and the quality of assembly quality will directly have influence on quality and the working life of mechanical transmission performance.
The parts such as the gear in machine driving, belt wheel, worm gear, shaft coupling, bearing, adopt interference fit or interference fits to be coupled to each other with axle, and supported to bear the load acted on axle by bearing, to realize gyration transferring power.
All parts that adopts interference fit or interference fits to be coupled to each other with axle (or casing) all need to carry out the pressure assembling, and abbreviation press-fits.Usually part appellation shafting components gear, belt wheel, worm gear, shaft coupling, bearing, axle sleeve etc. directly contacted with axle.Shafting components available pressure machine in assembling press-fits, also available hand hammer hammering assembling.Traditional manual installation efficiency is low, and labour intensity is large, hammering rapid wear surface of the work, and assembly quality can't guarantee, and noise is large, operating environment is poor, seldom adopts now; Usually adopt ordinary press to press-fit, although pressure head center and table top center when mounted, but because the foozle that press-fits part and press-fited part makes axle He Kong center deviation occur, there will be impact, vibrations or jitter phenomenon while now press-fiting, sometimes defective work piece, same assembly quality can't guarantee.
Although the appearance of the interior clamping telescopic press head of centre deviation self adaptation and three-jaw expansion floating pressure head is arranged, but two ball thrust bearings are housed between its upper connecting base and lower connecting base, because it relatively wastes material and process and assemble complicated structure, can not detect the size of pressure assembling force, so there is no promotion and application widely in addition.
Summary of the invention
The invention provides and a kind ofly can realize that Axial parts coordinates the centralized positioning deviation press-fit use automatically to revise indenter device, be arranged on forcing press and can realize that Axial parts coordinates the centralized positioning deviation while press-fiting automatically to revise centering, detects pressure assembling force simultaneously.
Technical scheme of the present invention is for this reason, and the centralized positioning deviation is revised indenter device automatically, comprises pressure head, it is characterized in that: be provided with lower connecting base above described pressure head, lower connecting base is outward an outer step boss, is inside a through hole, is provided with rubber spring in through hole; Lower connecting base top is provided with upper connecting base, and upper connecting base has central shaft, and central shaft is provided with deep gouge outward; Rubber spring in central shaft and lower connecting base through hole is installed togather; Be provided with the aligning thrust bearing between the outer step boss of the deep gouge of upper connecting base and lower connecting base.
Improvement to such scheme is: the aligning thrust bearing is comprised of two seat rings and ball assembly, and the roller surface of one of them seat ring is arranged to plane.
Improvement to such scheme is: the through hole in lower connecting base is a step through hole, forms a cavity between step through hole and pressure head; Be provided with block in cavity, block is spacing and be bolted on the central shaft of upper connecting base at the step place, makes upper and lower Connection Block become as a whole.
Improvement to such scheme is: be provided with pressure sensor above upper connecting base.
Beneficial effect:
The aligning thrust bearing is housed between upper connecting base and lower connecting base in the present invention, can realizes axially and radial motion; Rubber spring utilizes the sphere-contact of aligning thrust bearing to roll when press-fiting and the rubber spring strain realizes automatically revising deviation centering, and can automatically reset.
It is in order to allow ball realize radial motion in axially-movable, to have enlarged the scope of radial motion that the roller surface of a seat ring of aligning thrust bearing is arranged to plane, namely to the expanded range of automatic correction deviation.
The use of block makes upper and lower Connection Block become as a whole, conveniently uses and installs.
Upper connecting base upward pressure sensor is for detection of the size of pressure assembling force.
The present invention is arranged on forcing press and can realizes that Axial parts coordinates the centralized positioning deviation while press-fiting automatically to revise centering, detects pressure assembling force simultaneously; Utilize the characteristic of rolling friction and rubber spring strain, can realize that Axial parts coordinates the centralized positioning deviation while press-fiting automatically to revise centering, and can realize automatically reseting, detect the size of pressure assembling force simultaneously by pressure sensor.This apparatus structure is simple, press-fits precision high, and pressure assembling force is stable, and efficiency is high, the characteristic that noise is little, and the axle that can be widely applied to the plant equipment such as automobile mechanical, engineering machinery, ship machinery, aviation machine, light industry and machinery is press-fiting of key components and parts cooperation.
