Hub motor drum cover disassembling tool

Abstract

The invention provides a hub motor drum cover disassembling tool, and belongs to the technical field of machinery. The problem that an existing drum cover disassembling tool damages parts such as a rotating shaft and a bearing is solved. The hub motor drum cover disassembling tool comprises a rack, a sliding frame capable of moving up and down is arranged in the rack, a push-pull column capable of moving up and down relative to the sliding frame is arranged in the sliding frame, a containing hole allowing a motor shaft to be embedded is formed in the push-pull column, and a pushing part protruding outwards is arranged on the edge of the bottom of the push-pull column. A plurality of tensioning blocks which are arranged at intervals and surround the push-pull column with the push-pull column as the center are hinged to the bottom of the sliding frame, the inner side wall of each tensioning block is provided with an abutting face which is obliquely arranged downwards from inside to outside, and when the push-pull column moves upwards relative to the sliding frame, the pushing part can abut against the abutting faces, and the tensioning blocks can be pushed to rotate around hinge points and expand outwards; and a positioning structure for positioning the hub motor is arranged at the bottom of the rack. The drum cover disassembling tool realizes the disassembling of the drum cover under the condition that the hub motor is not damaged.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a drum cover removal tool for a hub motor. Background technique [0002] The hub motor is an important part of electric bicycles and electric motorcycles. The hub motor technology is also called the in-wheel motor technology. Its biggest feature is that it integrates the power device, transmission device and brake device The mechanical part of the vehicle is greatly simplified. [0003] When the wheel hub motor fails after installation, it needs to be disassembled for inspection. To disassemble the machine, the end cover of the wheel hub motor must be removed to detect the inside of the wheel hub motor. The existing tooling for dismantling, such as Chinese patent documents The material discloses a wheel hub motor end cover removal machine [application number: 202023207213.1; authorization announcement number: CN214014091U], which includes a top plate, a load ring and a bottom pla...

AI Technical Summary

Problems solved by technology

That is to say, the dismantling machine of this structure is to position the end cover, and then press the shaft directly through the column head to press the shaft out of the end cover. The shaft is the motor shaft. In the middle, the force on the rotating shaft deviates from the axial direction of the rotating shaft, which can easily lead to damage to the rotating shaft and bearings, and further damage to other parts of the hub motor
