Abstract
The utility model discloses an expansion-sleeve central spindle clamping device. The center of a central spindle is provided with a central hole; a pull rod is inserted into the central hole; one end of the central spindle is provided with a hole; a guide rod, an outer taper sleeve and an expansion sleeve are arranged in the hole; a guide rod hole is vertically formed on the outer taper sleeve; the guide rod is in clearance fit with the guide rod hole on the outer taper sleeve; the expansion sleeve is arranged outside the outer taper sleeve; an end cover is fixed on the central spindle, and is used for limiting the outer taper sleeve and the expansion sleeve; the central spindle is fixed on a lathe or a main shaft of a grinding machine; and the pull rod is fixed on a cylinder or a piston rod of an oil cylinder. The clamping device is used for clamping and fixing a motor shell, so that the structures of two end faces of the motor shell can be processed at the same time, the coaxiality of the processing structures of the two end faces is ensured, and the processing accuracy is enhanced.
Description
Technical field
The utility model relates to a kind of electric machine casing processing fixture.
Background technology
Motor is widely used in the transmission of various machines and equipment.Its structure is divided into stator and rotor, and the size of gaps between stator and the rotor can directly influence motor properties, and general air gap thickness is between the 0.2mm-1.5mm.And its size of gaps is directly determined by the axiality of electric machine casing iron core hole and two ends seam.The structure of tradition machined into electric machine casing both ends of the surface is to process an end earlier, with the electric machine casing upset reprocessing other end, needs manual touching the pillow then, revise repeatedly, measure, guarantee the axiality of two ends processing structure, its operation is loaded down with trivial details, and labour intensity is big, and machining accuracy is low.
Summary of the invention
The utility model solves the above-mentioned problems in the prior art exactly, a kind of ringfeder formula mandrel clamping device is provided, adopts this clamping device that electric machine casing is fixedly clamped, can process the structure of electric machine casing both ends of the surface simultaneously, guarantee the axiality of both ends of the surface processing structure, improve machining accuracy.
For addressing the above problem, technical solution of the present utility model is: a kind of ringfeder formula mandrel clamping device, and it comprises mandrel, guide rod, is fixed on pull bar, external conical sleeve, ringfeder and end cap on the guide rod; The center of mandrel has centre bore, is installed with pull bar in the centre bore, and an end of mandrel has the hole, and guide rod, external conical sleeve and ringfeder place in the hole, vertically has guide rod hole on the external conical sleeve, the guide rod hole matched in clearance on guide rod 2 and the external conical sleeve 3, and there is ringfeder the external conical sleeve outside; End cap is fixed on the mandrel, and its external tapered sleeve and ringfeder are spacing; Mandrel is fixed on the main shaft of lathe or grinding machine, and pull bar is fixed on the piston rod of cylinder or oil cylinder.
Because the utility model has adopted said structure, manually electric machine casing is placed on the ringfeder of mandrel one end, move by cylinder or oil cylinder pulling pull bar 1, driving guide rod and external conical sleeve moves with pull bar, when external conical sleeve moves with pull bar, strut ringfeder, ringfeder tensioner electric machine casing.Electric machine casing inside can be processed the structure of both ends of the surface so simultaneously by tensioner, guarantees the axiality of both ends of the surface processing structure, improves machining accuracy.It can also be by changing the electric machine casing that external conical sleeve and ringfeder are used to process various different sizes, greatly reduce working strength of workers, improve the production efficiency of lathe, guaranteed the axiality of iron core hole and two ends seam reliably, coaxiality deviation≤0.02-0.03mm.Because rising at ringfeder, this device justifies the coaxiality deviation≤0.003mm of back and mandrel, can effectively guarantee element precision, therefore can be widely used in processing sleeve part, particularly yielding thin-walled class sleeve part on the high-precision equipment such as numerically controlled lathe, numerical control cylindrical grinder.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As shown in Figure 1, present embodiment comprises mandrel 1, guide rod 2, is fixed on pull bar 6, external conical sleeve 3, ringfeder 4 and end cap 5 on the guide rod 2.The center of mandrel 1 has centre bore, is installed with pull bar 6 in the centre bore, and an end of mandrel 1 has the hole, guide rod 2, external conical sleeve 3 and ringfeder 4 place in the hole, vertically have guide rod hole on the external conical sleeve 3, the guide rod hole matched in clearance on guide rod 2 and the external conical sleeve 3, there is ringfeder 4 external conical sleeve 3 outsides.End cap 5 is fixed on the mandrel 1, and its external tapered sleeve 3 and ringfeder 4 are spacing.Mandrel 1 is fixed on the main shaft of lathe or grinding machine, and pull bar 6 is fixed on the piston rod of cylinder or oil cylinder.7 is electric machine casing.
