Aluminum alloy door and window positioning machining device

Abstract

The utility model provides an aluminum alloy door and window positioning machining device. The aluminum alloy door and window positioning machining device comprises a fixing frame, a positioning assembly and a positioning assembly. The inner side of the fixing frame is provided with a turn-over assembly. The turn-over assembly comprises two clamping frames which are rotatably arranged on the inner side of the fixing frame in a left-right mirror image mode, and rotating frames are fixedly arranged on the opposite sides of the two clamping frames. According to the aluminum alloy door and window positioning and machining device, the output end of the driving fixing air cylinder extends out to drive the connecting plate to rotate, then the connecting plate rotates and extends to enable the pressing plate to press downwards, and therefore the door and window are fixed; the door and window can be turned over after being fixed, the other face of the door and window can be machined conveniently and rapidly, the structure is simple and practical, the door and window can be turned over under the condition that the door and window are not taken down, and therefore the machining efficiency is ensured.
