Description

Ultrathin special-shaped metal sealing member fixture and application method thereof Technical Field The invention relates to the technical field of ultrathin special-shaped workpiece processing, in particular to an ultrathin special-shaped metal sealing piece tool clamp and a use method thereof. Background In the high-end manufacturing fields of aerospace, precise hydraulic transmission, high-end precise instruments and the like, the ultra-thin special-shaped metal sealing piece is used as a core basic sealing element, the machining precision and the forming quality of the ultra-thin special-shaped metal sealing piece directly determine the sealing performance, the working reliability and the service life of equipment, and extremely high requirements are provided for the suitability, the precision and the stability of a machining tool. The Chinese patent with the publication number of CN116175444A discloses a fixture, which comprises a base, a limiting component and a positioning mechanism, wherein the limiting component is arranged on one side of the base, the positioning mechanism comprises a positioning component and a locking component, the positioning component and the limiting component are arranged at intervals, and the positioning component is provided with a positioning groove. According to the technical scheme, a plurality of defects exist in the actual use process, for example, special fixtures with different specifications are required for machining the front surface and the back surface of the ultrathin special-shaped metal sealing piece, and the prior art is lack of an integrated tool design, so that a plurality of machining devices are required to be equipped for separate operation in the machining process, the equipment investment and the site occupation cost are greatly increased, the whole machining process is complicated, and the tool is time-consuming to change. And the front of the ultrathin special-shaped metal sealing piece is processed, the fixture clamping lacks the limiting and supporting effects on the metal sealing piece, and the metal sealing piece is easy to vibrate along with a cutter and affects the processing quality. When the reverse side of the ultrathin special-shaped metal sealing piece is processed, the metal sealing piece is required to be directly embedded in a limiting groove of a tool, the metal sealing piece is easy to be blocked in the limiting groove due to the problems of chip blocking, surface sticking, sticking and the like after processing is finished, if the ultrathin special-shaped metal sealing piece is taken in a mode that the ultrathin special-shaped metal sealing piece is tilted from a single side manually, plastic deformation is easy to occur due to poor rigidity of the ultrathin special-shaped metal sealing piece, the metal sealing piece is directly scrapped, and the manual workpiece taking operation is complex, so that the overall processing efficiency is reduced. The cooling liquid sprayed out of the liquid spraying pipe is easy to accumulate in the cutting groove and can not be discharged in time when the cutting groove on the back surface of the ultrathin special-shaped metal sealing piece is processed, so that the subsequent cooling liquid is difficult to reach the milling cutting surface, a continuous effective cooling effect can not be formed, and the ultrathin special-shaped metal sealing piece can not be rapidly dispersed out due to heat generated by continuous milling and is extremely easy to generate thermal deformation, and further the problems of processing size deviation, insufficient fitting precision of the sealing surface of the metal sealing piece and the like are caused. The metal chips generated by milling and cutting can remain in the cutting groove and the outer surface of the liquid extraction shell along with cooling liquid, if the metal chips are not cleaned timely, the chips can interfere the normal cutting action of the milling cutter, the surface precision and the dimensional precision of the machining of the cutting groove are affected, the milling cutter is likely to collapse and wear, and the service life of the cutter is shortened. The liquid inlet of the cooling liquid pumping and discharging adopts a fixed normally-open structural design, and meaningless negative pressure pumping and discharging is easy to lead metal chips to invade a pumping pipeline along with the cooling liquid to cause chip accumulation and blockage in the pipeline, thereby affecting the normal play of the subsequent pumping and discharging function, and also easily causing the phenomena of partial suction and cavitation and causing device damage. And when the suction pipe continuously sucks cooling liquid in the cutting groove through the liquid inlet, metal chips mixed in the cooling liquid are easy to be accumulated and blocked at the liquid inlet continuously, so that the liquid inlet is invalid, the cooling liquid in the ultrathin cutting gr
