Description

Technical Field

[0001] The utility model relates to the technical field of motor casing drilling tools, in particular to a motor casing positioning drilling tool. Background Art

[0002] The motor casing is one of the main parts of the motor. It generally refers to the external casing of the motor equipment. The motor casing is a protective device for the motor. It is made of silicon steel sheets and other materials using stamping and drawing processes. In addition, surface anti-rust and plastic spraying processes can well protect the internal equipment of the motor.

[0003] When processing the existing motor housing, it is necessary to drill a hole at one end of the opening, and after drilling, the motor housing can be connected to the end cover by bolts. The motor housing positioning drilling tool is a fixing fixture specially used for drilling the motor housing.

[0004] According to the search, Chinese patent literature, announcement number: CN220761910U, discloses a motor housing drilling tool. Through the design of the adjustment seat, screw, nut block, positioning base, connector and long slot, the motor housing is fixed by the positioning mechanism. If it is found that there is a deviation between the upper drill bit and the position where the motor housing needs to be drilled, the nut block is moved parallel to the screw by rotating the screw. The movement of the nut block drives the positioning base to move horizontally through the connector, and then the fixed motor housing can be adjusted horizontally to make the motor housing perpendicular to the drill bit. Although this drilling tool can improve the accuracy of drilling, it does not have the function of adjusting the angle of the motor frame. When drilling other positions of the motor housing, the motor housing needs to be clamped and fixed again, and the efficiency cannot be improved. Utility Model Content
