Description
Technical field
The utility model relates to the fixture of gear, is specifically related to the fixture of a kind of internal spline gear piece gear hobbing.
Background technology
When carrying out gear hobbing operation to inner spline gear sheet; often can occur because when clamping rigidity causes gear hobbing not, cutting force-induced error is larger; so that the precision of teeth portion is inadequate after gear hobbing operation; also can cause tooth surface damage because of gear piece pressure discontinuity, bring certain hidden danger to the production safety of product and product quality.
Summary of the invention
The purpose of this utility model is to provide one and can carries out clamping to inner spline gear sheet better and fix, and can improve gear hobbing precision with the internal spline gear piece gear-hobbing clamp improved the quality of products.
For achieving the above object, the utility model adopts following technical scheme: a kind of internal spline gear piece gear-hobbing clamp, comprise base, the mandrel of inserted base central blind hole, collet is provided with in the blind hole of described base, described mandrel is the spline mandrel that can match with the spline of internal spline gear piece and the lower end of described spline mandrel is fixed in described collet, described spline mandrel is arranged with successively and movably connects support set, lower backer and upper backer, the upper end of described spline mandrel is provided with screw thread and is furnished with the locking nut that can compress upper backer, described upper backer and lower backer be respectively equipped with the inner chamber and described upper backer that can hold internal spline gear piece step and lower backer respectively with internal spline gear piece on the upside of the flank of tooth and the flank of tooth of downside offset.
It is fixing that the utility model is undertaken in circumference by the spline fitted of gear piece and mandrel, and by upper backer and lower backer, the gear to gear piece both sides clamps that to carry out axially fixing.Connection support set is set between lower backer and base, cutting element in gear hobbing operation can be passed to base to the power that gear produces by support set, be evenly distributed to make contact force, avoid causing the flank of tooth of high load region destroy or fracture, improve the performance of its running, improve bearing capacity, extend the service life of inside spline wheel gear.Prevent gear piece play from causing the machining accuracy of the damage on the flank of tooth and teeth portion to be deteriorated.The setting of collet can be fixed spline mandrel better, prevents the play of mandrel axis, to ensure the gear hobbing precision of gear piece in gear hobbing operation.
As preferably, the lower end of described connection support set is provided with the groove that can adapt with the tapered jacket of described collet, and the tapered jacket on described collet top is positioned at described connection support set.The pressure that above-mentioned setting can make connection support set be subject to can pass to base better.
As preferably, described spline mandrel is provided with outwardly limiting section, and described connection support set is inserted in from the lower end of described spline mandrel, and described upper backer and lower backer are inserted in from the upper end of described spline mandrel.Spline mandrel is used to carry out the spacing of upward direction to connection support set, to ensure that connecting support set passes to base by power.
As preferably, the external diameter of described upper backer is identical with internal diameter with the external diameter of lower backer with internal diameter.External diameter is identical with internal diameter, and when can ensure that backer offsets with the gear piece of internal spline gear piece with lower backer, contact position is identical with contact area, with being compressed by internal spline gear piece better.
As preferably, the top of described spline mandrel is provided with the cone tank matched with lathe upper frame tail point.Lathe upper frame tail point can make the axial righting of the utility model in clamping process and hobbing process, to ensure gear hobbing precision.
As preferably, between described locking nut and upper backer, be provided with pad.
The utility model is used for inner spline gear folder on chip so that internal spline gear piece carries out gear hobbing operation, its clamping rigidity is higher, there is the deformation of tooth surface that can prevent gear piece in gear hobbing operation because undesirable element causes, the problem that teeth portion precision is inadequate, and the service life of inside spline wheel gear can be improved.
