The workbench is provided with a clamping assembly. When the device is used, the aluminum profile is placed on the workbench and positioned, and the left and right hand wheels are rotated to make the positioning clamping block clamp the aluminum profile, and then the clamping plate is pressed by the clamping cylinder to clamp the aluminum profile, and then the machine tool can be started for milling processing; the above device has the following shortcomings: when in use, the left and right clamping blocks can only clamp one aluminum door and window, which makes the efficiency low, and the waste chips generated during processing fall on the processing table and are inconvenient to clean up, which is easy to affect the processing. Utility Model Content

[0003] The utility model aims to provide a door and window end face milling and clamping mechanism, which can realize synchronous processing of multiple profiles, can collect the generated waste chips for easy cleaning, and improve the processing efficiency.

The four corners of the movable frame are fixed with a fixed frame through columns, the fixed frame is equipped with a hydraulic cylinder, and a pressure plate is fixed at the output end of the hydraulic cylinder. A clamping assembly is arranged on the movable frame, and the clamping assembly comprises a first screw rod rotatably connected to the movable frame and a plurality of clamping block groups located on the same horizontal line.

[0005] By adopting the above technical scheme, during processing, multiple profiles are placed side by side on the mobile frame, and each profile is placed in the clamping cavity between the first clamping block and the second clamping block. The driving component drives the first screw to rotate, so that the rotation of the first screw drives the multiple first clamping blocks to move synchronously toward the second clamping block, so as to realize positioning and clamping of multiple profiles. After clamping, the output end of the hydraulic cylinder extends to drive the pressure plate to descend and press on the multiple profiles, and then the shifting mechanism drives the mobile frame to move horizontally relative to the loading table, so that the milling cutter on the processing table can synchronously mill the ends of multiple profiles, thereby improving the processing efficiency. During the milling process, the waste generated falls into the waste trough, which is convenient for the operator to carry out subsequent cleaning.

Then the locking rod is loosened, and the lower end of the locking rod is embedded in the locking hole under the push of the locking spring, thereby completing the rapid relative fixation of the waste trough and the mobile rack. The reverse operation can complete the rapid relative disassembly of the waste trough and the mobile rack, making it convenient for the operator to pour out the waste in the waste trough.
