Description

Precision part turnover tool Technical Field The utility model belongs to the technical field of part machining, and particularly relates to a precision part turnover tool. Background When the precise metal parts of some cylinder hollow types are circulated, the turnover disc is directly used for circulation, the end face of the upper part is in direct contact with the bottom of the upper turnover disc, collision and friction are inevitably generated in the circulation process, the end faces of the parts are worn, the number of parts transported each time is more, the number of layers of the turnover disc is more, the stress of the bottommost part is larger, the end face damage is more serious, the parts are easy to scatter due to the adoption of the technical operation technology of technicians in the circulation process, and the follow-up production work is influenced. According to the precision part turnover tool disclosed in the patent number CN202322562760.9, the turnover tool comprises an outer frame, a support frame is fixedly connected to the inner part of the outer frame, sleeves are fixedly connected to four corners of the support frame, the sleeves are fixedly connected with the outer frame, and a through hole is formed in the middle of the sleeve in a penetrating mode. Above-mentioned scheme still has certain technical defect at in-process of in-service use, because the diameter of loop bar can't be adjusted according to the diameter of the accurate metal part of cylinder cavity class, when leading to the part cover on the loop bar, can't be rather than accurate matching, the in-process that leads to turnover, the part rocks, thereby make loop bar and the inner wall of part take place the friction, cause the condition of part inner wall fish tail, threaded rod and screw hole at bracing piece both ends all with bracing piece fixed connection moreover, lead to installing the both ends to the outer frame that utilizes the bracing piece, can only rotate simultaneously, the operation degree of difficulty is great, be unfavorable for the quick installation between two frames, we propose a precision part turnover frock for this reason.
