Problems solved by technology

For a new product, everything needs to be started from scratch, and there is a lot of repetitive work, which can save time and energy. Moreover, the manufacturing cycle of tooling is longer, which wastes a lot of materials and processing man-hours. It is difficult to adapt to the rapidly changing market requirements, especially It is because our factory has made great efforts in product development in recent years, and is tired of coping with technical preparations by working overtime all year round; a large number of fixtures with similar structures take up a lot of space in the workshop; when producing connecting rods of each model, a large number of fixtures need to be replaced and adjusted. Machine tools, long lead times for production

Abstract

The invention discloses a group technology machining method of connecting rods. The method comprises the steps that according to the connecting rods to be machined, the connecting rods are classified based on the same or similar appearance, and the unified locating reference of following machining is achieved; and the connecting rods comprising the same machining elements are arranged on the same machining equipment for machining, a corresponding group technology is selected for machining the connecting rods, furthermore, the appearance of the connecting rods to be machined is used as the unified locating reference, a workblank side face is subjected to finish machining, the size is controlled to be in the workblank tolerance range, and based on a workblank subjected to side face finish machining, a connecting rod machining clamp matched with the shape of the workblank subjected to side face finish machining is used for fixing. According to the method, large risks are avoided, technology debugging time is shortened, and the process design time and a large amount of energy of technologists are saved.

Description

technical field [0001] The invention belongs to a processing method of connecting rods, and relates to a group processing method of connecting rods. [0002] Background technique [0003] In recent years, with the demand of the market, our company has produced many types of diesel engines, and there are many types of corresponding diesel engine connecting rods. There are obvious characteristics of multi-variety and small-batch production in the connecting rod production unit. The current technology has been Can not meet the needs of the market. [0004] The structure of the connecting rod of the high-power medium-speed diesel engine is similar, only the difference is in size. [0005] In the past, there was no uniform standard for connecting rod technology, and the positioning references were different. There were large and small head holes for positioning, bolt holes for positioning, and side positioning for positioning. The inconsistency of the positioning methods ha...
