Description
[technical field]
The utility model relates to field of machining, relates in particular to a kind of aligning anchor clamps, is specifically related to a kind of aligning anchor clamps of clamping finish forge spare.
[background technology]
Known, the blank of bearing ring is finish forge spare, when lathe processing external diameter is the bearing ring of φ 62～φ 300, for satisfying many specifications, in enormous quantities, high efficiency, high-quality processing, the anchor clamps that use in the Vehicle Processing process have been proposed very high requirement, and at present the forging internal expansion type clamping fixture that bearing industry is commonly used comprises substantially: the hard pawl anchor clamps of aligning, internal expansion type spring perch and from the soft pawl anchor clamps of car circle.
Above-mentioned three class anchor clamps respectively have advantage, deficiency is also respectively arranged, the aligning of the hard pawl anchor clamps of aligning, durability, security is all good, but its alignment pin difficulty of processing is bigger, after the holding workpiece to the circle of workpiece beat the levelling difficulty bigger, the most outstanding shortcoming is exactly low precision, power chuck wherein is connected with the head of a bed of lathe by three screws, power in the lathe spindle back and forth moves axially centre bolt, starlike sphenoid on centre bolt is done servo-actuated accordingly, owing to it restriction has axially been arranged as the moving jaws that wedge gap cooperates with starlike sphenoid simultaneously, the harmomegathus that can only do radially moves; Gripper jaw wherein screws in the compound arc groove of changing pawl, and be in correct position, alignment pin and replacing pawl tight fit, after the chuck jaw assembling, three chuck jaws are installed in the appropriate location of three moving jaws of chuck with screw with it respectively, the rack tooth of the moving jaws of chuck and replacing pawl is apart from 1.5mm " the moving jaws tooth pitch 2.5mm that the D320 chuck is used ", namely adjusting step pitch is 1.5mm or 2.5mm, experienced operating personnel are through after suitably levelling is operated, gripper jaw is clamp axis bearing ring internal diameter preferably, the bearing ring outside diameter runout that is held can reach certain level, but finish forge spare can't use these anchor clamps to process safely, and along with the industry competition aggravation, uses the quantity of finish forge spare more and more, the allowance of forging is more and more littler, and the deficiency that overcomes this kind anchor clamps is made use of momentum inevitable.
And the spring perch of internal expansion type, this jig Design is clamping turner part aperture surface, it has, and clamping is firm, safety, durability is good, and is easy to use, and is half measure at these anchor clamps of internal diameter clamping of finish forge spare, because it does not have aligning, causing can't clamping at the finish forge spare of thin-walled, because its harmomegathus amount is also limited, the forging big at the internal diameter size deviation can not use " safe clamping range is chuck basic size ± 0.3 " in addition.
From the soft pawl internal diameter anchor clamps of car circle, because its chuck jaw is connected three chuck jaws on three moving jaws of power chuck with screw, because coupled chuck is general, so such anchor clamps scope of application is big, cost of use is low, and maximum defective is to be can not aligning equally, it reruns a movie the roundness defect of forging get off, next is because the piece-holder face is smooth, cause forging is clamped not strongly, easily cause the processing excircles vertical difference bad, so such anchor clamps can only clamping be processed the big part of wall thickness coefficient, the part that wall is thin can't be used these anchor clamps.
In sum, existing internal expanding anchor clamps commonly used can not satisfy the Vehicle Processing clamping of finish forge spare and the less forging of allowance preferably, especially can not satisfy the clamping Vehicle Processing of book wall forging.
