The invention relates to the field of cutting machining, in particular to a positioning clamp suitable for cutting machining of a SiCp / Al thin-wall part. The clamp is composed of a supporting device, a clamping device and a positioning device. The supporting device comprises a base and a positioning sliding block. The clamping device comprises two same fastening screws, two same chucks and two same springs; the positioning device comprises a positioning plate, an electric telescopic rod, a supporting rod, a motor and a positioning screw. An electric telescopic rod driven by a motor is arranged on a base, the motor is fixed on the base through a supporting rod, the electric telescopic rod is connected with a positioning plate, a clamping head A, a spring and a fastening screw are arranged on the left side of the base, a sliding rail is welded on the right side of the base, a sliding block is arranged on the sliding rail, and a positioning screw, a clamping head B, a fastening screw and a spring are arranged on the sliding block. And a positioning plate slideway is arranged in the middle of the base. The clamp solves the problems that when an existing clamp for cutting machining is used for cutting machining of a SiCp / Al thin-walled workpiece, the workpiece cannot be rapidly installed and positioned, and the work efficiency is seriously affected by repeated assembling, disassembling and positioning of the workpiece.
Description
technical field [0001] The invention relates to the field of cutting processing, in particular to a positioning fixture suitable for cutting processing of SiCp / Al thin-walled parts. Background technique [0002] Compared with traditional matrix alloys, aluminum-based silicon carbide composites have high specific strength, specific stiffness, excellent high-temperature mechanical properties, low thermal expansion coefficient, and excellent wear resistance. They are widely used in aviation, aerospace, automotive, electronics, and transportation industries Very broad application prospects. Aluminum-based silicon carbide composites have attracted more and more attention due to their excellent properties, but the difficulty in achieving high-efficiency and precise machining has seriously restricted the popularization and application of SiCp / Al composites. [0003] Therefore, it is necessary to conduct a large number of cutting experiments on SiCp / Al composite materials. In the c...
