Problems solved by technology

The disadvantage of this is that the cost is high, and an electrode must be made for each size of the bell mouth. For small-sized products, the electrode loss is large, and the processing efficiency is low.
It is also easy to damage the original oval bell mouth shape during the grinding and polishing process

Embodiment 1

[0042] See attached Figure 1~Figure 6 As shown, a processing device for an elliptical groove is used to process an elliptical groove on a workpiece 3. The workpiece 3 has a through hole, including a clamping mechanism for clamping the workpiece 3, a fixed pulley 9, and a tensioner 1 , grinding motor 12, take-up motor 7 and grinding line 12, wherein:

[0043] Described clamping mechanism comprises a workpiece chuck 8 and a support 14, and described workpiece chuck 8 is rotatably arranged on the support 14, and when workpiece 3 is assembled on the workpiece chuck 8, the rotational axis of workpiece chuck 8 and workpiece 3. The axes of the upper through holes are overlapped and arranged, the workpiece chuck 8 is connected to the output shaft of the rotating motor 5, and the rotating motor 5 drives the workpiece chuck 8 to rotate;

[0044] The fixed pulley 9 and the workpiece chuck 8 are relatively movable in a direction parallel to the axial direction of the through hole, so as...

Embodiment 2

[0061] The difference between this embodiment and the first embodiment is that in the first embodiment, the workpiece chuck 8 rotates, and the fixed pulley 9 moves along its axial direction relative to the workpiece chuck 8, while in this embodiment, the workpiece chuck 8 is relatively positioned, The fixed pulley 9 is set to be moved relative to the workpiece chuck 8 and to be rotated relative to the workpiece chuck 8, as long as the relative rotation between the workpiece chuck 8 and the fixed pulley 9 can be realized and the axial movement along the through hole on the workpiece 3 can be achieved, the rest Parts are the same as those in Embodiment 1, and will not be repeated here.

Abstract

An ellipsoidal groove machining device is used for machining ellipsoidal grooves in workpieces. At least one through hole is formed in a workpiece. The ellipsoidal groove machining device is characterized by comprising a clamping mechanism used for clamping the workpiece, a fixed pulley, a tensioner, a grinding motor, a winding motor and a grinding wire, wherein a workpiece chuck rotates relative to the fixed pulley and is movably arranged; when the workpiece is assembled on the workpiece chuck, the rotating axis of the workpiece chuck or the fixed pulley is coincided with the axis of the through hole in the workpiece; the tensioner is used for controlling the tension of the grinding wire; an eccentric wheel is arranged on an output shaft of the grinding motor; a winding wheel is arranged on an output shaft of the winding motor; the grinding wire is output from the tensioner, is wound around the fixed pulley, then, penetrates through the through hole in the workpiece, and then, is wound around the eccentric wheel and the winding wheel; and an acute angle is formed between one section of grinding wire between the fixed pulley and the through hole and the axis of the through hole, and the opening of the acute angle is arranged, facing the fixed pulley.

Description

technical field [0001] The invention relates to the field of groove processing, in particular to a processing device for elliptical grooves. Background technique [0002] With the continuous improvement of motor manufacturing requirements, the processing requirements for the rotor and stator windings are also getting higher and higher, especially almost all motor rotor windings and stator windings have a large aspect ratio, and the tension changes on the long side and the short side are different, so Traditional cylindrical guide pins are no longer suitable for motor manufacturing, and flat guide pins with an elliptical shape are gradually becoming dominant. The shape of the oval flat guide pin outlet is an oval bell mouth, and transitions to the inner hole of the guide pin in a smooth arc to prevent the enameled wire from being pulled. [0003] The traditional method of processing an elliptical bell mouth is often to process an electrode with an elliptical bell mouth shape...
