On the milling cutter head, a side positioning device and a symmetrical reversible pressing device are arranged on the material receiving table along the center line of the receiving work table. The side positioning device and the symmetrical reversible pressing device are in line with the The steel plate springs are matched, and a positioning hole corresponding to the center hole of the steel plate springs is arranged on the material receiving workbench.

The power head frame of the utility model carries two power heads, and there are left and right screw rods to adjust the distance between the two power heads. The power head is driven by the motor to rotate the milling cutter disc to complete the milling action. There is an adjustable screw rod under the power head, which can adjust two power heads at the same time, or adjust one power head separately. Install the power head on the milling cutter head, so that the milling cutter head can process the steel plate on one side, ensuring that the steel plate can enter the processing area horizontally. Before starting the milling power head, adjust the screw rod of the milling power head to make the distance between the two milling cutter heads large enough, then clamp the workpiece, perform center and lateral positioning, start the milling cutter head, and the screw rod of the power head aligns the tool After processing.

The feeding mechanism of the edge milling machine is driven by a three-phase asynchronous motor (0.75Kw torque 200N.m) coupled with an XLY3-59 planetary cycloid reducer to drive the screw drive, so that the material receiving platform can move forward and backward. Conversion is done by travel switch.

The material-bearing workbench of this edge milling machine is responsible for the material-bearing function. The central positioning device is used for the positioning of multiple steel plates processed at the same time. The side positioning device cooperates with the central positioning device to position the steel plates to ensure that the size of the milling surface of the steel plate can be reversed symmetrically. The clamping device is used for the operator to press and fix the two sides of the milling steel plate to ensure that the multiple steel plates will not vibrate or move during the milling process. At the same time, the clamping device can be opened to facilitate loading and unloading.

The utility model solves the long-standing practical difficulty in processing both sides of the spring steel plate ear in a convenient, fast and reasonable manner, greatly improves the surface quality of the reed ear processing, and the efficiency is improved, and the mechanism of the edge milling machine is reasonable , high positioning accuracy, greatly improving the surface quality of the milling edge processing of the middle part of the reed, low equipment maintenance cost, simple, safe and reliable operation, meeting the requirements of on-site use, and has high practical value.

The utility model has the advantages of reasonable structure, convenient operation, safe and reliable production, guaranteed processing precision, improved product quality, improved production efficiency and reduced labor intensity of workers.
