Abstract
The utility model relates to a spline tension sleeve fixture for grinding straight-tooth bevel gear wheel end face outer circles. The spline tension sleeve fixture is a dual-location fixture capable of achieving tooth profile pitch circle location and spline pitch circle location. The spline tension sleeve fixture comprises a taper mandrel, a locating ring, a hex head screw, a steel ball, a steel wire, a bevel washer, a spline tension sleeve, an open washer and a hex nut. The locating ring is assembled on the taper mandrel, the movable steel ball is connected to the locating ring, the bevel washer is assembled on the taper mandrel, the hex head screw is arranged on the locating ring in the radial direction, the spline tension sleeve is in taper fit with the taper mandrel, and the open washer and the nut are arranged at the right end of the taper mandrel. According to the spline tension sleeve fixture, the spline tension sleeve is tensioned outwardly by screwing the nut so that a bevel gear can be tensioned. The spline tension sleeve fixture is simple in structure, accurate in location, capable of achieving shaft neck total run-out and planar total run-out with a spline pitch circle as reference for a half axle gear, good in consistency, and especially suitable for grinding machining of the straight-tooth bevel gear wheel plane outer circles after heating.
Description
Technical field
The utility model belongs to machine industry, machining manufacturing technology field, particularly a kind of spline expansion sleeve fixture of grinding spur bevel gear end face cylindrical.
Background technology
Automobile half axle gear is a kind of straight bevel gear of transmitting torque, the benchmark of this spur bevel gear design is the internal spline pitch circle, the flank profil back side and axle journal cooperate with adjacent elements, its quality of fit directly affects the transmission quality of automobile half axle gear, design internal spline and semiaxis external splines fit clearance are smaller, so the plane total run-out take the spline pitch circle as benchmark and axle journal total run-out are had relatively high expectations.Automobile half axle gear will carry out necessary heat treatment after flank profil is shaped, after the heat treatment end face and axle journal are ground processing.Existing technology adopts the anchor clamps of profile of tooth location, owing to become large take spline as the benchmark tooth runout after the gear heat treatment, and these anchor clamps are as positioning datum with the spur bevel gear profile of tooth, can only guarantee plane total run-out and axle journal total run-out take the spur bevel gear profile of tooth as benchmark, but can not guarantee with axle journal total run-out and the plane total run-out of spline as benchmark.
The utility model content
The utility model is mainly for the deficiencies in the prior art, providing a kind of locates simultaneously with spur bevel gear profile of tooth and spline pitch circle, the spur bevel gear profile of tooth is with movable steel ball fixed output quota product axial location, spline is determined the products radial position with the spline ringfeder, reaches axle journal total run-out and the plane total run-out of grinding axle shaft gear take spline as benchmark after the heat treatment.
The technical scheme that its technical problem that solves the utility model adopts is: the spline expansion sleeve fixture of grinding spur bevel gear end face cylindrical, it comprises mandrel, locating ring, hex screw, steel wire, bevel washer, spline ringfeder, open washer and hex nut.It is characterized in that: the left end assembling and positioning ring (2) of mandrel (1), the steel ball (4) that connects by steel wire (5) is housed on the locating ring (2), right-hand member assembling spline ringfeder (7) and open washer (8) and the hex nut (9) of locating ring (2), bevel washer (6) is contained in the medium position of mandrel, and hex screw (3) is contained in the side of locating ring (2).Described spline ringfeder, its endoporus is Mohs 3# tapered hole, the tapering hole wall is provided with an open slot, and spline ringfeder and taper shank mandrel screw radially tensioner bevel gear by hex nut, thereby has guaranteed axle journal total run-out and the plane total run-out of bevel gear spline as benchmark.The Parameter of spline of spline ringfeder is according to axle shaft gear internal spline parameter designing, and the spline type is involute, and the number of teeth, modulus, pressure angle are identical, but difference be the spline ringfeder stride rod apart from than axle shaft gear internal spline interrod spacing little (0.02-0.04) mm.
The beneficial effects of the utility model are: increase spline internal expanding structure on the basis of spur bevel gear profile of tooth location, radial location is accurate, guaranteed axle journal total run-out and the plane total run-out requirement of bevel gear take spline as benchmark of processing, simultaneously with spline pitch circle location mill processing axle journal plane, realized combining of positioning datum and design basis.
Description of drawings
The structural representation of the spline expansion sleeve fixture of the spur bevel gear of grinding shown in accompanying drawing end face cylindrical.
The specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments for the below.
Differential side gear spline ringfeder grinding processing jig shown in the drawings, it comprises mandrel 1, locating ring 2, hex screw 3, steel ball 4, steel wire 5, bevel washer 6, spline ringfeder 7, open washer 8 and hex nut 9.Described spline ringfeder 7 its endoporus are Mohs 3# tapered hole, its Parameter of spline is according to spur bevel gear internal spline parameter designing, the spline type is involute, the number of teeth, modulus, pressure angle are identical, but difference be the spline ringfeder stride rod apart from than spur bevel gear internal spline interrod spacing little (0.02-0.04) mm.
Case study on implementation of the present utility model is the end face Cylindrical Grinding Processes after the heat treatment of finish forge straight-tooth circular cone axle shaft gear.The mandrel that at first edge is prepared (1) is installed on the lathe with the locating ring (2) that is connected steel wire (5) to connect steel ball (4), centering, the end that guarantees four steel balls is jumped, the footpath is jumped and is no more than 0.01mm, and the master gear of axle shaft gear is contained on the anchor clamps compresses, guarantee the jumping of master gear end, the footpath is jumped and is no more than 0.015mm, after take off master gear, spline ringfeder (7) is contained in the axle shaft gear, axle shaft gear and spline ringfeder (7) together are contained in upper profile of tooth and the two location of spline of guaranteeing of mandrel (1), hex screw (3) screws out and guarantees not contact bevel washer (6), load onto afterwards open washer (8), screw hex nut (9), make outside the spline ringfeder (7) and rise, until the spline endoporus of the processed straight bevel gear of tensioner, guarantee that axle shaft gear is in place, beginning grinding axle shaft gear.After grinding finished, reverse operating screwed out first the radial force that hex nut (9) discharges axle shaft gear, screwed hex screw (3) contact bevel washer (6) again and made the gear axially loaded withdraw from spline ringfeder (7) and axle shaft gear.
The utility model is simple in structure, and accurate positioning can be satisfied axle journal total run-out and the plane total run-out of the axle shaft gear take the spline pitch circle as benchmark, and high conformity, is particularly suitable for the grinding after the heat treatment of spur bevel gear.
