Description
Technical field
The utility model relates to a kind of centralized positioning deviation press-fiting for Axial parts cooperation and automatically revises 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 by bearing, are supported to bear the load acting on axle, 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 pressure assembling, and abbreviation press-fits.Conventionally part appellation shafting components gear, belt wheel, worm gear, shaft coupling, bearing, axle sleeve etc. directly being 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 cannot guarantee, and noise is large, operating environment is poor, seldom adopts now; Conventionally 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 Zhou Hekong center occur deviation, while now press-fiting, there will be impact, vibrations or jitter phenomenon, sometimes defective work piece, same assembly quality cannot guarantee.
Although there is the appearance of the interior clamping telescopic press head of centre deviation self adaptation and three-jaw expansion floating pressure head, 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, in addition can not detect the size of pressure assembling force, so there is no promotion and application widely.
Summary of the invention
The utility model provides a kind of Axial parts of realizing to coordinate the centralized positioning deviation press-fit use automatically to revise indenter device, is arranged on forcing press, can realize Axial parts and coordinate the centralized positioning deviation while press-fiting automatically to revise centering, detects pressure assembling force simultaneously.
The technical solution of the utility model is for this reason, and centralized positioning deviation is revised indenter device automatically, comprises pressure head, it is characterized in that: above described pressure head, be provided with lower connecting base, 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; Between the outer step boss of the deep gouge of upper connecting base and lower connecting base, be provided with aligning thrust bearing.
Improvement to such scheme is: 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; In cavity, be provided with block, block is spacing and be bolted on the central shaft of upper connecting base at step place, makes upper and lower Connection Block become as a whole.
Improvement to such scheme is: above upper connecting base, be provided with pressure sensor.
Beneficial effect:
Aligning thrust bearing is housed between upper connecting base and lower connecting base in the utility model, can realizes axially and radial motion; Rubber spring utilizes the sphere-contact of aligning thrust bearing to roll when press-fiting and rubber spring strain realizes correction deviation centering automatically, and can automatically reset.
It is in order to allow ball realize radial motion in axially-movable, to have expanded the scope of radial motion that the roller surface of a seat ring of aligning thrust bearing is arranged to plane, namely the expanded range to automatic correction deviation.
The use of block makes upper and lower Connection Block become as a whole, easy to use and installation.
Upper connecting base upward pressure sensor is for detection of the size of pressure assembling force.
The utility model is arranged on can be realized Axial parts and coordinate the centralized positioning deviation while press-fiting automatically to revise centering on forcing press, detect pressure assembling force simultaneously; Utilize the characteristic of rolling friction and rubber spring strain, can realize Axial parts and coordinate the centralized positioning deviation while press-fiting automatically to revise centering, and can realize and automatically reseting, by pressure sensor, detect the size of pressure assembling force simultaneously.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.
