Description
Technical field
This utility model relates to a kind of production frock, especially relates to a kind of transmission gear endoporus polishing frock.
Background technology
Transmission gear uses grinding to make the internal diameter of bore reach required dimensional requirement after Overheating Treatment, but the bore surface roughness after grinding does not meets use requirement, and surface exists lofty salient point and cusp.Existing processing method is the size surplus of reserved 0.02mm, uses honing rod to the honing of bore surface, although the surface after honing is more smooth, however it is necessary that and re-establish new precision under the precision that destruction is original.And honing rod honing mode is rigidity grinding, need to ensure that honing rod is coaxial with workpiece, the i.e. fixture of honing rod, workpiece and fixing workpiece is required to coaxial fixing, higher to the axial positioning precision of honing rod and the axial positioning accuracy request of work-piece fixation clamp, slightly deviation is easy for causing bore error excessive, need repeatedly to calibrate, reduce production efficiency.
Utility model content
This utility model is primarily directed to the problems referred to above, it is provided that a kind of can be effectively improved bore surface roughness, reduce the salient point on bore surface and cusp, relatively low to the positioning accuracy request of machining tool, be easy to the transmission gear endoporus polishing frock that quickly produces.
The purpose of this utility model is mainly achieved by following proposal: a kind of transmission gear endoporus polishing frock, fixture including the gear for fixed transmission, also include the supporting rod being coaxially disposed with fixture, supporting rod is driven by motor, clamping hole it is provided with in the middle part of supporting rod, clamping is provided with flexible polishing roller in hole, and supporting rod is provided with gap slot near one end of fixture around supporting rod, and supporting rod outside screw connects locking nut.Transmission gear can be fixedly clamped by fixture, the axis making gear is the most coaxial with the axis of supporting rod, supporting rod is driven by motor and rotates, arrange clamping hole at the middle part of supporting rod, clamping arranges flexible polishing roller in hole, and flexible polishing roller is flexible structure, polishing process is flexible grinding, can be to the salient point on bore surface and cusp grinding, stock removal is less, will not destroy the original precision in bore surface.And owing to polishing process is flexible grinding, between supporting rod and the axis of fixture slightly deviation time, also the size of bore will not be caused excessive impact, therefore, whole polishing process is the highest to the axial positioning accuracy request of supporting rod and fixture, without repeatedly calibrating, improve production efficiency, it is achieved quickly produce.Supporting rod is provided with gap slot near one end of fixture around supporting rod, the part enabling gap slot both sides is inwardly concentrated, and when polishing roll inserts in clamping hole, screws locking nut, tightening nut is utilized to make the part of gap slot both sides inwardly concentrate and step up polishing roll, it is achieved the location of polishing roll.
As preferably, described polishing roll includes positioning bar, around the polished ball of location bar setting, for connecting location bar and the flexible link of polished ball.Location bar inserts in the clamping hole in supporting rod, utilizes the part of gap slot both sides to step up to position bar, it is achieved the location of polishing roll.Arranging polished ball around location bar, utilize polished ball to bore surfacing, polished ball and bore contact position are point cantact, and stock removal is less.Flexible link is used for connecting polished ball and location bar, when the body diameter that polished ball is constituted is more than bore, flexible link can slight deformation, polished ball is made to enter in bore, flexible link is limited can be deformed by bore, polished ball can be applied the support force expanded outwardly simultaneously, increase the grinding dynamics of polished ball.
As preferably, described flexible link is around the axis Spiral distribution of location bar, and the rotation direction of flexible link is identical with the rotation direction of motor.Pressure between polished ball and bore and support force can be guided around the axis Spiral distribution of location bar, flexible link, make the direction of power not be positioned at the radial direction of polishing roll, it is simple to flexible link compressive deformation by flexible link.The rotation direction of flexible link is identical with the rotation direction of motor, and when motor rotates and drives location bar to rotate, the rotation direction of flexible link is identical with location bar direction of rotation, makes polished ball uniform with bore skin-friction force.
As preferably, described supporting rod is the conical surface near one end outer surface of fixture.Supporting rod is the conical surface near one end outer surface of fixture, when locking nut screws at the conical surface, it is possible to clamping gap slot two side portions, enables the part of gap slot both sides to clamp the location bar of flexible polishing roller.
As preferably, described gap slot is distributed evenly around supporting rod.Gap slot is distributed evenly around supporting rod, it is ensured that the clamping force that the part of gap slot both sides positions bar to flexible polishing roller is uniform.
As preferably, described fixture is scroll chuck structure.Fixture is scroll chuck structure, it is possible to increase the firmness of fixed gear, and ensure that the axis of gear is almost identical with the axis of fixture.
As preferably, the external diameter 1-2mm bigger than bore aperture of described flexible polishing roller.The flexible link of flexible polishing roller can be by the pressure slight deformation on bore surface, the support force of polished ball be enough to bore surfacing by flexible link to be ensured simultaneously, thus it is guaranteed that the external diameter of flexible polishing roller 1-2mm bigger than bore aperture.
Therefore, transmission gear endoporus buffer's harness of the present utility model is for following advantage: flexible polishing roller is flexible structure, and polishing process is flexible grinding, it is possible to salient point and the cusp grinding to bore surface, stock removal is less, will not destroy the original precision in bore surface.And owing to polishing process is flexible grinding, between supporting rod and the axis of fixture slightly deviation time, also the size of bore will not be caused excessive impact, therefore, whole polishing process is the highest to the axial positioning accuracy request of supporting rod and fixture, without repeatedly calibrating, improve production efficiency, it is achieved quickly produce.Supporting rod is provided with gap slot near one end of fixture around supporting rod, the part enabling gap slot both sides is inwardly concentrated, and when polishing roll inserts in clamping hole, screws locking nut, tightening nut is utilized to make the part of gap slot both sides inwardly concentrate and step up polishing roll, it is achieved the location of polishing roll.
