Description

Technical Field

[0001] The invention relates to the field of motor manufacturing, in particular to an automatic end plate pressing machine for a motor stator. Background Art

[0002] The stator end plates are usually located at both ends of the motor stator, which can locate the coil and lead wire. Its purpose is to isolate the coil from the pivot and effectively prevent short circuit.

[0003] At present, stator end plates are manually installed on both ends of the motor stator, which not only has low work efficiency and high labor intensity, but also is prone to improper installation. Although stator end plate pressing equipment has appeared on the market, such as the stator end plate automatic pressing machine disclosed in prior art 200920127865.9, the following problems exist in the working process: 1. The stators need to be lifted one by one from the stator conveyor line by a lifting cylinder and placed in the stator flip template for end plate press-fitting. After the press-fitting is completed, the stators need to be placed on the stator conveyor line one by one by a lifting cylinder. Continuous press-fitting cannot be achieved, resulting in low work efficiency. 2. After the stator is placed in the stator flip template, it needs to be moved horizontally by the rack II driven by the template flip cylinder. Rack I The horizontal movement of I drives the gear shaft II meshing with the rack II to rotate, and the rotation of the gear shaft II drives the stator flip template to flip, so that the stator flip template is rotated from the vertical direction to the horizontal direction. Not only is the structure complicated, but the steps are cumbersome; 3. When the end plate is loaded, it is necessary to drive the end plate chuck to descend along the sliding sleeve through the chuck lifting cylinder, and the clamping cylinder drives the end plate chuck to clamp the end plate. After clamping, the end plate chuck is driven to rise by the chuck lifting cylinder, and the rack I driven by the rotating cylinder moves horizontally. The movement of the rack I drives the gear shaft I meshing with the rack on it to rotate. The rotation of the gear shaft I drives the fixedly connected chuck lifting cylinder to rotate from the vertical direction to the horizontal direction, so that the axis of the end plate is also rotated from the vertical direction to the horizontal direction. Not only is the structure complicated, but the steps are cumbersome. Summary of the invention
