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. Excavators, also known as excavators and excavators, are earthmoving machines that use buckets to excavate materials above or below the bearing surface, and load them into transport vehicles or unload them to stockyards. With the development of the industry, excavators It has become one of the most important construction machinery in engineering construction, and the slewing platform is one of the important components connecting the excavator bucket console and the crawler-type mobile base. In the production process of the slewing platform, professional assembly tooling is necessary. indispensable. In the existing technology, when the rotary platform is assembled, it is mostly assembled on an ordinary platform. Since there is no good fixing device, during the overall assembly, in order to better assemble the rotary platform, it is necessary to manually mark the rotary platform. Platform positioning is very troublesome. Therefore, we propose a final assembly tool for excavator rotary platform. The purpose of this utility model is to provide an excavator rotary platform assembly tooling, the tooling is provided with a flat plate, a support plate, a rotating column and a positioning frame on one side of the upper end of the base, and fixed welding on the other side of the upper end of the base There is a baffle, and the baffle is provided with a screw, a push plate and a knob. By turning the knob, the screw is driven to rotate, so that the push plate moves horizontally, and the distance between the push plate and the positioning frame can be adjusted according to the actual size of the rotary platform, so To achieve fast and accurate positioning, convenient operation, reduce marking, reading ruler and other work, through hinged side plate on the side of the abutment, a spring latch is arranged on one side of the side plate, and a plug is opened on the abutment The side plate can be fixed by the spring bolt, so that the side plate can assist in fixing the side of the rotary platform, so that the rotary platform can be fixed more firmly during assembly. 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 is provided with a flat plate, a support plate, a rotating column and a positioning frame on one side of the upper end of the base, and on the other side of the upper end of the base The baffle is fixed and welded, and the baffle is provided with a screw, a push plate and a knob. The screw is rotated by turning the knob, so that the push plate moves horizontally, and the distance between the push plate and the positioning frame can be adjusted according to the actual size of the rotary platform. , so as to achieve fast and accurate positioning, convenient operation, reduce scribing, ruler reading and other work; 2. The utility model is hinged with a side plate on the side of the base through a hinge, and one side of the side plate is provided with a spring latch. There is an insertion hole on the base, and one end of the spring pin is inserted into the insertion hole, and the side plate can be fixed by the spring pin, so that the side plate can assist in fixing the side of the rotary platform, so that the rotary platform can be It is more firmly fixed during assembly.
