[0001] The invention belongs to the technical field of milling machine processing, and particularly relates to an intelligent double-head end face milling machine and a working method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] With the diversification of the cross-section of aluminum alloy door and window assembly profiles and the size and style of finished windows, the requirements for the precision of the finished windows and the skills of technical workers have also increased accordingly; the original single-machine processing model has high skills requirements for technical workers. If the workers' skills do not meet the requirements, their production efficiency and the quality of doors and windows cannot be effectively guaranteed; currently, highly automated and intelligent equipment - aluminum alloy door and window assembly lines have become the preferred equipment for door and window production, and will inevitably become required equipment in the future; currently, there is no complete door and window assembly line in the existing technology that can solve the above problems, especially the seamless connection between each single machine to truly realize unmanned operation.

[0004] At present, double-head CNC end milling of aluminum alloy profiles can solve the above-mentioned problem of processing accuracy, but it still cannot achieve seamless connection with upstream and downstream processes in production, which leads to problems such as low production efficiency and high manpower investment.

The loading mechanism can quickly grab and place materials, and the retrieving mechanism can efficiently retrieve materials under the control of an electronic control unit. The movement and locking of the left and right milling devices of the entire equipment, the movement of the retrieving mechanism, and the operation of the loading mechanism are all uniformly controlled by the electronic control unit.

The fixed bracket, vertical bracket, and horizontal bracket of the retrieving mechanism are made of high-strength profiles, and the guide rails are dovetail grooves, which ensure the accuracy of the gripper retrieving materials, thereby indirectly guaranteeing processing accuracy. This reduces the robot's retrieving movements, shortens the material placement time, and speeds up the processing process. At the same time, the left and right milling devices adjust the spacing according to the material size through the electronic control unit and are locked by a clamp to prevent movement during operation, ensuring milling accuracy and reducing the defective rate caused by precision problems. This not only improves production efficiency, but also reduces the skill requirements for operators, reduces the impact of human factors on the processing process, and improves the stability and reliability of the production process.
