The invention provides a processing method of an integrated horn submarine gate electrode. The method comprises the following steps: cutting an electrode copper plate material, preparing materials of an electrode milling machine, processing via a grinding machine, forming and processing a first side of the electrode copper plate material and forming and processing a second side of the electrode copper plate material, wherein the step of processing via the grinding machine is characterized by processing positioning grooves used for subsequently clamping in the upper end surface and the lower end surface of the electrode copper plate material. The processing method is simple in steps, short in period and low in processing cost. A clamping fixture used in the electrode processing method comprises a fixture base and a fixture extending device, wherein the fixture base and the fixture extending device are provided with positioning convex ribs, positioning grooves and central through holes; through cooperation of the central holes and positioning structures, the electrode material to be processed is stably fixed on the clamping fixture, so that the processing accuracy is ensured. The processing method and the clamping fixture are suitable for clamping and processing various types of electrodes.

The invention relates to the field of mechanical processing, and discloses a taper hole drilling machine tool for steering knuckle arms, which includes a workbench, a tool driving device provided with the workbench, and a servo sliding table slidably connected to the workbench. The tool driving device includes an electric control box , column, spindle box, servo thrust motor, three spindles are connected to the spindle box for rotation, the axes of the spindles are on the same plane, and the spindles are respectively connected with drilling drills, rough reaming drills and fine reaming drills, and the servo sliding table is connected with a device clip assembly. The present invention has the following advantages and effects: by connecting the drilling bit, the rough reaming bit and the fine reaming bit to the three main shafts respectively, the drilling and reaming process is performed on the taper hole end, which improves the machining efficiency and machining accuracy, and reduces the burden on the operator. Technical dependence; the tensioning part pushes the tensioning sleeve to expand to tighten and position the bolt hole, which ensures that the steering knuckle arm can rotate, avoids the deformation of the steering knuckle arm, and improves the stability of the taper hole position.
