Abstract
The utility model discloses an inner bore rolling cutter. The inner bore rolling cutter comprises a mandrel, a mandrel mount, a bushing and a ferrule structure. The mandrel mount is arranged at the tail end of the mandrel through a thread structure. The mandrel is sleeved with the bushing. The ferrule structure is arranged on the connecting portion between the mandrel mount and the mandrel and arranged at the tail end of the bushing in a sleeved mode. The front end of the bushing is provided with an adjusting nut which is fixedly connected with the mandrel through a thread structure. The mandrel mount is provided with three roller structures which are movably arranged in a groove-type structure at the tail of a ferrule. The roller structures are conical column structures. Moving gaps are reserved between the roller structures and the mandrel mount. According to the inner bore rolling cutter, the requirement for concentricity between a part and the cutter in the machining process is not high, so that clamping difficulty is lowered; the high accuracy degree of the part machined through the inner bore rolling cutter can be ensured, and the roughness can reach 0.4-0.2 micron; meanwhile, the inner bore rolling cutter is structurally easy to dismantle and convenient to replace, the service life of the inner bore rolling cutter is prolonged, and the cost is lowered.
Description
Technical field
The utility model relates to the processing unit (plant) field of mechanical endoporus, relates in particular to the special rolling depression cutter of a kind of endoporus.
Background technology
Before internal rolling cutter uses, processing endoporus adopts inner circle to grind to process, but the processing of inner circle mill exists following some shortcoming:
1) working (machining) efficiency is not high: the grinding amount of feeding is little;
2) roughness does not reach requirement: in Grinding Process, can affect workpiece surface roughness in a large amount of metal removal and the emery wheel sand ends of generation;
3) size is unstable: grinding wheel spindle is tiny, and the length that overhangs is large, poor rigidity, and flexible and vibration when grinding, machining accuracy and surface roughness are difficult to control
4) processing cost is high: grinding wheel diameter is little, and easily blunt needs often to revise and change;
5) in Grinding Process, produce amount of heat and can cause Surface Burning in Grinding, residual stress and face crack, need by a large amount of mobile cooling fluids.
Utility model content
For the problem of above-mentioned existence, the utility model object is to provide a kind of and controls precisely, the special rolling depression cutter of endoporus that working (machining) efficiency is high.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of internal rolling cutter, described rolling depression cutter comprises mandrel, mandrel edge head, lining and ferrule arrangement, described mandrel edge head is arranged on mandrel tail end by helicitic texture, on described mandrel, be set with lining, described ferrule arrangement is arranged on the connecting portion of mandrel edge head and mandrel, described ferrule arrangement is sleeved on lining tail end, the front end of described lining is provided with regulating nut, between described regulating nut and mandrel, be fixedly connected with by helicitic texture, described mandrel edge head is provided with three roller construction, described roller construction is movably arranged in the trench structure of lasso afterbody, described roller construction is tapered pole body structure, and be reserved with free gap between mandrel edge head.
Three roller construction are freely movable and have taper fit with mandrel edge head in can the groove in ferrule arrangement; Can adjust lining and the position of ferrule arrangement on mandrel by regulating nut, and then adjustment roll rod structure is inlayed coordinating of head with mandrel, and then complete the adjusting work of cutter, while cutter in use three roller construction can regulate automatically, automatically adjust within the specific limits the axiality of revising between part, reduce clamping difficulty, improve machining accuracy.
As a kind of improvement of the present utility model, described mandrel edge head and the afterbody of roller construction are provided with screw and regulate fixing.
As a kind of improvement of the present utility model, the front end of described regulating nut is provided with check nut, and described check nut is movably connected on mandrel by helicitic texture, and check nut, for the position of secured adjusted nut, prevents the change in size in process.
As a kind of improvement of the present utility model, between described lasso and lining, be provided with return groove, in described return groove, be provided with return spring structure adapter sleeve coil structures and lining; Return spring can make ferrule arrangement return to initial position not idle time, makes the working size of three rollers formation in minimum of a value.
The utility model has the advantage of: cutter of the present utility model, to add man-hour not high for the concentricity requirement of part and cutter, reduces clamping difficulty; During for grinding, need to try after mill is adjusted just can process; Use the part of this tool sharpening can ensure high-precision requirement, roughness can reach 0.4 ~ 0.2 μ m, uses this tool sharpening can improve more than 3 times working (machining) efficiencies than grinding; Rolling tool structure is quick detachable simultaneously, can be convenient for changing, and improves cutter life, cost-saving.
