Description

Technical Field

[0001] The utility model relates to the technical field of measurement and tooling, in particular to a device for measuring the relative position between a commutator segment and a sleeve keyway during the assembly process of a DC motor commutator. Background Art

[0002] At present, the commonly used structure of the DC motor commutator is a V-ring clamping structure, which consists of commutator segments and insulating segments evenly spaced to form a cylindrical whole, with V-grooves processed at both ends, and the upper and lower ends are respectively fastened as a whole with sleeves and pressure rings with V-grooves by bolts. There are insulating mica rings between the commutator segments and sleeves, and between the commutator segments and pressure rings. There are keyways in the sleeves, and the keyways of the commutator segments and sleeves have certain relative position requirements. If the relative position deviation of the keyways of the commutator segments and sleeves is too large, it will affect the armature wire embedding, and even affect the motor commutation, causing the motor to burn out. During the assembly process of the commutator segments and sleeves, the relative position of the commutator segments and sleeve keyways is usually measured by the sample marking method, which requires a high level of operating experience and operation level, and the measurement error is large. Utility Model Content

[0003] The utility model overcomes the assembly requirement of the relative position of the commutator segment and the sleeve keyway during the commutator assembly process. The device can accurately check the relative position of the commutator segment and the sleeve keyway, and can flexibly replace the device centering plate, positioning key and guide plate, which is suitable for the inspection requirements of the commutator segment and the sleeve keyway of different commutators. The structure is compact and simple, and the work efficiency is also improved.

[0004] The technical solution of the utility model is: a commutator assembly relative position measurement device, characterized in that it includes:

[0005] Connecting beam 1, first bolt 2, second bolt 3, guide plate 4, positioning key 5, positioning plate 6, screw 7, pressing plate 8;

[0006] The positioning key and the guide plate are connected by a first bolt 2 and a second bolt 3 respectively through a connecting beam 1;

[0007] The positioning plate 6 and the positioning key 5 are connected with screws 7 and a pressure plate 8;

[0008] The positioning key 5 is smaller than the size of the keyway inside the commutator sleeve and plays a guiding role, and can slide into the commutator from top to bottom along the keyway;

[0009] The positioning plate 6 is disc-shaped, and its outer diameter is smaller than the inner diameter of the commutator sleeve, and also plays a guiding role in the inner circumferential direction of the commutator sleeve;

[0010] The guide plate 4 is connected to the connecting beam 1 by a second bolt 3. The top of the guide plate is smaller than the thickness of the commutator sheet on the sheet changer and is in the shape of a sharp knife, which can be easily aligned with the middle position of the thickness of the commutator sheet.

[0011] The beneficial effect of the utility model is that the requirement of checking the relative position of the commutator segment and the sleeve keyway during the commutator assembly process can be easily achieved, and different guide plates, positioning keys and positioning plates can be easily replaced to adapt to the assembly requirements of various series of commutators, reduce labor intensity and measurement errors, improve work efficiency during the assembly process, and make it easier to ensure the assembly quality of the product.
