The utility model relates to the technical field of combined machine tools, in particular to a two-way expanding tool bit of a combined machine tool. The body flange is a main body structure of the expanding tool bit; the movable gear shaft penetrates through the body flange and is meshed with the left side helical teeth and the right side helical teeth; the left moving block is fixedly connected with the left helical tooth, and the right moving block is fixedly connected with the right helical tooth; the middle pressing plate, the right pressing plate and the left pressing plate press the left moving block and the right moving block on the body flange through bolts; the left side helical teeth and the right side helical teeth are bidirectional asymmetric helical racks, the left moving block and the right moving block are driven to move independently in two directions through axial movement of the moving gear shaft, and multi-procedure machining is completed through one-time feeding. The utility model provides the combined machine tool expanding tool bit which is compact in structure, zero in transmission clearance and capable of supporting two-way synchronous or asynchronous machining, the problems of low efficiency, poor precision, insufficient reliability and the like of traditional equipment are fundamentally solved, and technical guarantee is provided for machining of high-precision complex parts.

A die and method for drilling the inner liner of a composite material fairing, belonging to the field of composite material parts processing. The die comprises: a clamping device positioned and detachably fixed to the upper end face of the die body; an annular boss on the outer periphery of the upper end face of the die body; multiple clamping plates and multiple locators disposed on the annular boss; the clamping plates and multiple locators being positioned and detachably fixed to the annular boss; and multiple through holes on the side of the annular boss for drilling holes in the inner liner of the fairing by inserting a drill bit. The method involves: clamping and positioning the inner liner of the fairing to be drilled between the die body and the clamping device, and clamping it with multiple clamping plates and positioning it with multiple locators; mounting a milling cutter on the shaft of a handheld angle grinder, and then fitting a drilling tool bushing onto the outside of the milling cutter; starting the handheld angle grinder and performing the cutting operation using the milling cutter; removing the milling cutter and installing the drill bit for drilling. This invention is used for drilling the inner liner of a fairing.

The utility model discloses a milling cutter for machining an aluminum alloy product, and relates to the technical field of milling. The milling cutter for aluminum alloy product machining comprises a cutter handle and a mounting block arranged on the outer wall of the cutter handle, a connecting mechanism is arranged on the outer wall of the cutter handle, and a milling mechanism is arranged at the end, away from the cutter handle, of the mounting block; the connecting mechanism comprises a connecting part and a control part; the connecting mechanism has the technical effects that when the connecting mechanism is installed, only the connecting plates need to be inserted into the fixing sleeves and aligned with the inserting grooves, the lifting ring is controlled to slide down, the wedge-shaped blocks push the control rods to rotate, then the inserting blocks are driven to be inserted into the inserting grooves to complete preliminary locking, and then the connecting mechanism can be stably fixed by screwing down the extrusion screws; reverse operation is carried out during dismounting, no complex tool is needed, the mounting and dismounting time is greatly saved, meanwhile, the multiple fixing structures guarantee the connection stability, and the screw rod penetrates through the fixing sleeve and the connecting plate for secondary fixing.
