Description

Technical Field

[0001] The utility model relates to the field of commutator manufacturing, and specifically, it is a device for arranging commutator segments. Background Art

[0002] At present, when manufacturing a commutator, it is necessary to first arrange the commutator segments and place insulating materials between the segments. Due to the special structure of the commutator, it is necessary to ensure the perpendicularity of the commutator segments and make the commutator segments and the insulating materials fit tightly. However, in traditional commutator manufacturing, a ring-shaped tooling is used to fix the commutator segments and the insulation together, and then the perpendicularity of the commutator segments and the insulating materials is adjusted. The perpendicularity error is large, the fit between the commutator segments and the insulating materials is not tight, and it is not convenient for processing. This is obviously not an ideal state for the quality of the commutator. Summary of the Utility Model

[0003] The utility model overcomes the problems of large perpendicularity error and poor tightness between the commutator segments and the insulating materials in the existing segment arranging method. The utility model provides a segment arranging device that can achieve rapid positioning and arranging, and the device is convenient for processing during segment arranging.

[0004] The technical solution of the utility model is: the segment arranging device is composed of a positioning part and a locking part. The positioning part includes: a positioning axis and a chassis. The positioning axis is fixed on the chassis, and a positioning groove is opened on the positioning axis for positioning the commutator segments. The locking part includes: a pressing cylinder, an outer hoop and an inner hoop. The inner hoop is composed of two semi-circular rings. There is an inclination on the outer side of the inner hoop that meshes with the outer hoop. The outer hoop meshes with the inner hoop, and the pressing cylinder is placed on the end face of the outer hoop.

[0005] The beneficial effect of the utility model is that it can simultaneously achieve positioning and pressing, ensuring the perpendicularity of the commutator segments and the pressure between the segments; since the positioning part and the locking part are integrated into one, the device has good connection coupling, a more compact structure, and at the same time makes the device convenient for disassembly and assembly, and effectively improves the efficiency of commutator manufacturing; the commutator segment arranging device provided by the utility model can be realized by using existing technologies, and the overall manufacturing and assembly of the device are highly feasible.

The pressing cylinder 1 is placed on the end face of the outer hoop 2.

[0011] The specific operation process of the device: Place the device on the workbench of the hydraulic press, insert the commutator segments into the positioning axis for positioning, start arranging the segments. After the arranging is completed, press the inner hoop tightly against the outer circumference of the commutator segments, place the outer hoop and the pressing cylinder, start the hydraulic press. Under the action of the pressing cylinder, the outer hoop starts to mesh with the inner hoop, and the inner hoop presses the commutator segments and the insulating material to the specified size. Remove the positioning axis and it can flow into the next process.
