China's machinery manufacturing industry is in an industrial state of transformation and development. The industry's technical level is developing rapidly, production concentration is high, and market access is very large. Our company has advanced machinery manufacturing technology, a group of outstanding machinery manufacturing R&D personnel and perfect standardized quality supervision and management, and is committed to the globalization, networking, automation and green development of the machinery manufacturing industry. Excavator, also known as excavator, also known as excavator, is an earth-moving machine that uses a bucket to excavate materials above or below the bearing surface and load it into a transport vehicle or unload it to a stockyard. The materials excavated by the excavator are mainly soil, coal, silt, soil and rock after pre-loosening. The development of excavators is relatively fast and has become one of the most important construction machinery in engineering construction. Common excavator structures include power units, working devices, slewing mechanisms, manipulation mechanisms, transmission mechanisms, walking mechanisms and auxiliary facilities. When the excavator is assembled, the slewing platform tooling is used. The existing slewing platform tooling is simple in production, complicated in positioning and fixing, and the clamping and positioning accuracy of the main part and the left and right beams is not high, resulting in uneven gap and poor size of the cover during overall assembly, which affects the appearance of the whole machine. Therefore, we need to propose a slewing platform tooling for excavators with high clamping accuracy. The purpose of the utility model is to provide a slewing platform tooling for excavators with high clamping accuracy. By integrating the installation process of the main body and other parts, it can realize fast and accurate positioning, facilitate operation, reduce scribing, read ruler work, and have high tooling accuracy. , and easy to maintain; it can be processed as a whole to ensure the uniformity of the platform and the accuracy; use two parallel positioning axes to ensure the accurate positioning of the main part, and other parts are positioned by the locking rod, which is convenient for clamping and ensures the shape size, in order to solve the problems raised in the above background art. Compared with the prior art, the beneficial effects of the present utility model are: 1. The utility model realizes fast and accurate positioning by integrating the installation process of the main body and other parts, which is convenient for operation, reduces scribing, reads ruler work, and has high tooling precision, and easy to maintain;
