The invention relates to a positioning clamping device for mining vertical-ring connector chain rings. The device is characterized by comprising a numerical control rotation disc (1), a rotation tail stock (2) and a connection bridge plate (4), wherein the numerical control rotation disc (1) and the rotation tail stock (2) are arranged on a large base plate (3), two ends of the connection bridge plate (4) are connected with the numerical control rotation disc (1) and the rotation tail stock (2) respectively, and a positioning clamping fixture is fixedly arranged on the connection bridge plate (4). The positioning clamping device for mining vertical-ring connector chain rings has the advantages that machining tasks of matching positions of a vertical-ring connector chain ring can be completed through one-step clamping, multi-process repeated positioning errors are prevented, errors in a machining process are controlled effectively, and the production efficiency is improved; the positioning clamping device is simple and convenient to operate and reduces the operator labor intensity effectively; and the positioning clamping device is high in positioning accuracy, forging errors of batch blank parts can be adjusted flexibly, and quality problems of blank part alignment are controlled effectively.
Description
technical field [0001] The invention relates to a positioning and clamping device for a mine-used vertical link connecting link. Background technique [0002] Recently, the construction of high-yield and high-efficiency working face mines has been significantly accelerated, the efficiency of fully mechanized coal mining has been greatly improved, and the use of heavy and super-heavy scraper conveyors has increased. Therefore, higher requirements are put forward for the key parts on the transmission parts of the conveying equipment. The connecting link is the key moving force-bearing part on the scraper chain of the scraper conveyor of coal mining equipment. Due to the influence of design, manufacture, use and maintenance, and special working surface conditions, the scraper chain often breaks, which seriously affects the mining. normal production. Among the reasons for the damage of the scraper chain, the fracture failure ratio of the connecting link is relatively large. T...
