Background In the technical fields of machining and surface treatment, polishing of a titanium alloy watch case is a key process. Titanium alloys are widely used in the manufacture of wristwatch cases due to their excellent properties of high strength, low density, corrosion resistance, etc. However, the high hardness and toughness of titanium alloys makes their polishing work extremely difficult. The traditional polishing process mainly depends on manual operation, which is not only low in efficiency, but also can lead to the difficulty in ensuring the consistency of the polishing quality and the yield of the product due to the instability of the manual operation. In the prior art, the polishing of the watch case of the titanium alloy watch usually adopts a manual operation mode. Although the method can achieve a certain polishing effect, the consistency of polishing quality and yield of products are difficult to ensure due to instability of manual operation. In addition, the cost of manual polishing is higher, the labor intensity of workers is high, the operation environment is poor, and the requirement of mass production cannot be met. Therefore, the existing titanium alloy watch case polishing technology has a plurality of problems in practical application, and a new, more efficient and more stable polishing method is highly needed to improve the consistency and yield of the polishing quality of products, reduce the cost, reduce the labor intensity of workers and meet the requirement of mass production. The invention provides an automatic titanium metal watch case polishing method, which realizes a high-efficiency and stable polishing process by adopting a five-axis linkage polishing device and a special jig. The method not only improves the consistency and yield of polishing quality, but also reduces labor cost and labor intensity, improves the operating environment and meets the requirement of mass production. Disclosure of Invention The invention aims to provide an automatic titanium metal watch case polishing method, which solves the problems of poor polishing quality consistency, low efficiency, high cost, high labor intensity and the like in the prior art. In order to achieve the above purpose, the invention provides an automatic titanium metal watch case polishing method, which aims to solve the problems of poor polishing quality consistency, low efficiency, high cost, high labor intensity and the like in the prior art. The method realizes a high-efficiency and stable polishing process by adopting the five-axis linkage polishing device and the special jig. Specifically, the method comprises the steps of installing a watch case sample on a special jig, fixing the jig on a C shaft through bolts, adhering and fixing polishing sand paper on a throwing disc, and driving the throwing disc by a servo motor. In the processing process, the polishing wheel and the sample piece rotate around the shaft respectively, and the surface treating agent is sprayed on the joint of the polishing sand paper and the product to be polished through a nozzle. The method is realized by the steps of firstly carrying out laser carving treatment on a material of a watchcase, then placing a watchcase rough blank subjected to laser carving treatment on a watchcase fixing jig, carrying out rough polishing treatment on the side edge position of the watchcase by using a polishing machine, then placing a watchcase product subjected to preliminary polishing on the watchcase fixing jig, carrying out rough polishing treatment on the side edge position of the watchcase by using the polishing machine, then placing the watchcase product subjected to rough polishing on the watchcase fixing jig, carrying out finish polishing on the side edge position of the watchcase by using the polishing machine, then placing the watchcase product subjected to rough polishing on the watchcase fixing jig, carrying out wire drawing treatment on the side edge position of the watchcase by using the polishing machine, then placing the watchcase product subjected to rough polishing on the watchcase fixing jig, carrying out rough polishing on the watchcase product subjected to rough polishing on the side position of the watchcase by using the polishing machine, and finally carrying out rough polishing on the watchcase product subjected to finish polishing on the watchcase by using the polishing machine. After the steps are finished, the processed watchcase product is sent to a cleaning tank for cleaning so as to remove polishing liquid left on the surface of the product, and finally the watchcase product after cleaning is sent to a detection chamber for full detection, so that the polishing quality of the product is ensured to be qualified.
