Abstract
The utility model provides a plunger chip for processing the end face of a bearing roller. The plunger chip for processing the end face of the bearing roller comprises an external sleeve, a shaping core, a boss rod, a pressing cushion, a prestressed casing and a buffer cushion, wherein the shaping core is embedded in a center hole in the external sleeve, and further supported by a clamping platform arranged on the inner wall of the external sleeve; the boss rod penetrates into a through hole in the center of the shaping core; the other end of the boss rod is connected with the pressing cushion arranged on the end part of the external sleeve; the annular prestressed casing is arranged between the shaping core and the inner wall of the external sleeve; and the buffer cushion is arranged between the shaping core and the clamping platform. With the adoption of the plunger chip for processing the end face of the bearing roller, the plunger chip is divided into the shaping core and the boss rod of which the position can be adjusted; after being abraded, the boss rod can be enabled to recover to the initial state via a mode that the position of the boss rod is adjusted by the pressing cushion or replaced; in such a way, the plunger chip can be kept under a high precision state all the time; meanwhile, the prestressed casing and the buffer cushion are added; and therefore, the impact force which the plunger chip suffers is buffered, and the service life is prolonged.
Description
Technical field
The utility model relates to field of machining, specifically a kind of drift for the processing of bearing roller end face.
Background technology
Roller bearing is a kind of as bearing, be widely used in the fields such as various big machineries, vehicle, roller in the roller bearing utilizes pressing to produce in the prior art, first material is made diel, then the shape of mould and the form fit of roller to be processed use drift and die that material is squeezed into predetermined shape.
Roller punch of the prior art is the integral type structure, be about to material and become mould with lathe through processes such as car, mills, then produce roller with pressing, but owing to adding precision and the life problems in man-hour, the mould that causes producing has deviation in precision, thereby the roller precision that causes pressing to be produced is overproof or scrap; Simultaneously, same mould has certain wearing and tearing in process of production, also causes precise decreasing, and this just need to change whole mould again, has reduced production efficiency, and simultaneously, the frequent mould has also caused the raising of production cost.
The utility model content
The boss precision that the utility model exists for the roller punch that solves prior art and produce differs and weares and teares and causes the problem of scrapping, a kind of drift for the processing of bearing roller end face is provided, this drift adopts each assembly of split type processing, then assemble, guaranteed the unification of precision, simultaneously, go back capable of regulating after the wearing and tearing or change assembly, need not change whole mould, make it revert to the front precision of wearing and tearing.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of drift for the processing of bearing roller end face, comprise outer sleeve, forming core, boss bar and clamping pad, forming core is embedded in the centre bore of outer sleeve, and supported by the Ka Tai that the outer sleeve inwall arranges, outside end face at forming core is provided with shaping groove, the boss bar is located in the through hole at forming core center, and the one end is arranged in the shaping groove, and the other end is connected with the clamping pad that the outer sleeve end arranges.
In the utility model, be provided with cushion pad between described forming core and the card platform;
Described boss bar is comprised of two sections different cylinders of diameter, and the diameter of an end that links to each other with clamping pad is greater than the diameter of the other end, step surface and the cushion pad of two sections cylinder junctions are oppositely arranged, and have the gap of 0.2-0.8mm, and the periphery of boss bar and Ka Tai applying;
Be provided with the Pre-stress cover of annular between the inwall of described forming core and outer sleeve;
Described clamping pad is connected with the inwall of outer sleeve by the screw thread on its periphery, and has the gap of 0.2-0.8mm between clamping pad and the card platform.
In the utility model, described clamping pad can be designed as the solid cylinder structure, and the one end is connected with the boss bar, and the other end protrudes outer sleeve 0.5mm, and is slidingly matched by little gap between its circumferential surface and the outer sleeve; Under this structure, when installing and using, an end and the lathe stress surface of clamping pad protrusion outer sleeve are close to, and boss bar height is non-adjustable, but the boss bar that can more renew.
In the utility model, described clamping pad and boss bar also can be designed to integrative-structure, and the diameter of clamping pad is greater than the diameter of coupled boss bar, and outer sleeve 0.5mm is protruded in the bottom of clamping pad, and is slidingly matched by little gap between its circumferential surface and the outer sleeve.
In the utility model, the specification of shaping groove is according to different roller specifications design, and the boss bar protrudes in the inside of shaping groove, and the height of protrusion is also according to different roller specifications design.
In the utility model, the steel that the material selection of Pre-stress cover and cushion pad is softer than forming core material get final product.
In the utility model, clamping pad is connected with the inwall of outer sleeve by the external screw thread on the excircle, the bottom also is provided with is convenient to the groove that screwdriver or other instruments turn clamping pad, turns clamping pad by tool using, can adjust the position of boss bar, after having grown service time, because the boss bar that punching press causes wearing and tearing are so that precise decreasing can turn clamping pad, thereby make the boss bar rise to original position, recover original precision.The damage of boss bar or wearing and tearing will prior to forming core, therefore also can change the boss bar, make mould can continue to use in the reality.
In the utility model, the active force buffering that the mould side was subject to when Pre-stress cover can be with punching press, thus effectively protect mould impaired, increase the service life; The downward impulsive force buffering that cushion pad can be subject to mould, the protection mould; The effect of further shock absorbing power is not only played in the gap that exists between the upper surface of cylinder under cushion pad and the boss bar, has kept simultaneously the space that the boss bar moves up.
In the utility model, the gap between clamping pad and the card platform is for after the wearing and tearing of boss bar, upwards turns the adjustment space that clamping pad makes the boss bar restore to the original state and reserve.
Beneficial effect: the utility model is by being divided into drift on forming core and the boss bar that can adjust the position, using a period of time, after the wearing and tearing of boss bar, adjust the position of boss bar or change the boss bar by clamping pad, drift make it return to original state, so that can remain under the high-precision state always; Increase simultaneously Pre-stress cover and cushion pad parts, cushioned the impulsive force that drift is subject to, prolonged service life.
