Description
Technical Field
The invention belongs to bearing processing equipment, and particularly relates to a turning clamping device for finely processing a flange surface and an outer circular surface of a conical bearing outer ring with a flange.
Background
The tapered roller bearing belongs to a split bearing, and an inner bearing component (comprising rollers, a retainer and an inner ring) and an outer ring of the bearing can be separated, so that the tapered roller bearing can be conveniently arranged on a shaft neck and a bearing seat; the inner ring and the outer ring of the tapered roller bearing are provided with tapered roller paths, and the rollers are also tapered, if the tapered surfaces extend, the vertexes of the tapered roller bearings intersect at one point of the bearing axis, so that the rollers of the tapered roller bearing can realize pure rolling on the roller paths; the tapered roller bearing is suitable for bearing radial load, unidirectional axial load and radial and axial combined load, and the axial load capacity of the tapered roller bearing depends on a contact angle alpha, namely the angle of an outer ring raceway, and the larger the contact angle alpha is, the larger the axial load capacity is.
At present, due to the installation and positioning requirements, the flange is designed on the outer ring of the conical bearing, the inner assembly is the same as that of a single-row conical roller bearing, the conical roller bearing with the flange can be axially positioned on a bearing seat, the configuration design of the bearing and the structure of the bearing seat are simplified, but due to the fact that the flange is designed on the outer ring in multiple ways, the vertical flange surface and the horizontal outer ring surface are required to be precisely machined, the traditional fine machining mode of the flange-bearing outer ring flange surface and the outer ring surface is divided into two steps, 2 pieces of equipment are adopted for machining, one grinding outer ring surface and one grinding flange surface are adopted, the equipment investment of the mode is more, the working procedures are more, the whole grinding production line can be occupied during machining, the positioning references of the numerical control lathe machining flange surfaces are inconsistent, the machined product size is inconsistent, the conical bearing outer ring with the flange is concentric with a clamp, and the like, and the quality of a final finished product is affected.
Disclosure of Invention
The invention aims to solve the problems that in the prior art, the number of equipment required for finish machining of the flange surface of the outer ring of the conical bearing with the flange and the outer ring surface is large, the working procedures are large, the positioning references are inconsistent, the concentricity difference is large, and the like, and provides the clamping device for turning the outer ring of the conical bearing with the flange, which has the advantages of small equipment required number, few working procedures and capability of effectively ensuring the dimensional precision of the flange surface of the outer ring and the concentricity of the outer ring surface and a roller path.
The invention solves the technical problems by adopting the technical scheme that: the clamping device comprises a clamp seat, a taper sliding mandrel and a pressing plate, wherein one end of the clamp seat is provided with a clamping part, the clamping part consists of a clamping surface and a positioning shaft, the taper sliding mandrel is a truncated cone, the taper of the taper sliding mandrel is consistent with the taper of the track surface of the conical bearing outer ring, the taper sliding mandrel is sleeved on the positioning shaft, the length of the positioning shaft and the length of the taper sliding mandrel are smaller than the width of the flange conical bearing outer ring, the pressing plate is positioned on one side of the taper sliding mandrel, the pressing plate is fixedly connected with the positioning shaft through a locking screw, an O-shaped sealing ring is arranged between the taper sliding mandrel and the clamping surface of the clamping part, the taper sliding mandrel is provided with an annular limiting groove, the O-shaped sealing ring is fixed in the annular limiting groove, and the clamp seat, the positioning shaft and the taper sliding mandrel are coaxial.
Optionally, the O-ring is coaxial with the positioning shaft.
Optionally, the cross section of the annular limiting groove is square.
The application mode and the principle of the invention are as follows: when the product is used, the clamp seat is arranged on a three-jaw chuck of a numerical control lathe, the outer ring of the flanged flange conical bearing is sleeved on a taper sliding mandrel, then the pressing plate is attached to the end face of the outer ring of the flanged flange conical bearing, then the pressing plate is connected with the positioning shaft through the locking screw, finally the locking screw is rotated, the outer ring of the flanged flange conical bearing is clamped on the clamp seat, then the tool is turned down, and the flange surface and the outer circular surface are sequentially turned through a program control tool;
before the locking screw is screwed down, the O-shaped sealing ring is fixed in an annular limiting groove on the large end face of the taper sliding mandrel, the annular limiting groove provides enough deformation accommodating space for the O-shaped sealing ring, and the O-shaped sealing ring is in a free state;
in the screwing process of the locking screw, the O-shaped sealing ring is axially extruded and deformed to generate reverse axial elastic force, and the elastic force generated by the deformation of the O-shaped sealing ring pushes the taper of the raceway surface of the outer ring of the flanged flange conical bearing to be clung to the taper of the taper sliding mandrel;
in the continuous screwing process of the locking screw, the axial force generated by the locking screw is larger than the elastic force generated by the deformation of the O-shaped sealing ring, the rolling way surface taper of the flange conical bearing outer ring and the conical surface of the taper sliding mandrel are clung together to continuously move axially until the end surface of the flange conical bearing outer ring is clung to the clamping surface of the clamp body, and the end surface positioning surface error caused by the fact that the end surface of the flange conical bearing outer ring and the clamping surface of the clamp body are clung in an untight manner is prevented;
after the outer ring of the conical bearing with the flange clings to the clamping surface of the clamping part, the clamping surface of the clamp body is always positioned when the numerical control lathe finishes machining the flange surface, and the starting position of the lathe tool feeding is unchanged when the numerical control lathe is used for machining the flange baffle plate, so that the dimensional consistency of the numerical control lathe is ensured; the conicity of the raceway surface of the conical bearing outer ring with the flange is consistent with and clung to the conicity of the conicity sliding mandrel, so that the concentricity of the outer circular surface of the conical bearing outer ring with the flange and the mandrel is ensured, and the size consistency of the outer circular surface of the bearing outer ring and the concentricity of the raceway are ensured during numerical control turning; thereby achieving the purposes of finishing the flange surface and the outer circular surface of the flange conical bearing outer ring by one cutter, clamping once and finishing once processing.
Compared with the prior art, the invention has the following beneficial effects: the invention uses turning instead of grinding, effectively reduces equipment investment, reduces working procedures, and improves the precision and the quality stability of the outer ring of the conical bearing with the flange.
