Description

Eccentric crankshaft carburizing treatment charging device Technical Field The utility model relates to a heat treatment tool, in particular to a furnace charging device for carburizing treatment of an eccentric crankshaft. Background In order to ensure that the rod body of the existing eccentric crankshaft has enough wear resistance, carburization is needed, and along with the increasing of the yield of the eccentric crankshaft, the number of push rod furnaces for carburization cannot meet the carburization of the eccentric shafts, so that the production efficiency and the exchange period of the product are affected. Disclosure of utility model Accordingly, it is necessary to provide an eccentric crankshaft carburizing treatment charging device in order to solve the above-described problems. In order to solve the technical problems, the utility model adopts the following technical scheme: The eccentric crankshaft carburizing treatment charging device is characterized by comprising a plate-shaped lower supporting disc and a plate-shaped upper positioning plate, upright posts are arranged between four corners of the lower supporting disc and the upper positioning plate, circular gaskets and fixing nuts are arranged on the upright posts, The lower supporting plate is provided with a plurality of protruding tips and a plurality of lower hollowed-out placing holes, the upper positioning plate is provided with a plurality of upper hollowed-out placing holes, An eccentric crankshaft is arranged between the lower hollow placing hole and the upper hollow placing hole, and a core rod is arranged in the center of the eccentric crankshaft. As a preferred embodiment of the utility model, the upper hollow placing hole and the lower hollow placing hole are square. As a preferred embodiment of the utility model, the tip is wedge-shaped. Compared with the prior art, the utility model has the following beneficial effects: The utility model provides an eccentric crankshaft carburizing treatment charging device, which is characterized in that a center and a square hole are customized on a lower locating plate, and the square hole is customized on an upper locating plate, so that the weight and cost of the device are reduced by light weight design, more eccentric crankshafts can be assembled by maximally utilizing space, meanwhile, the deformation of deep holes of products subjected to carburizing treatment can be greatly reduced by placing a customized core rod in the deep holes of the eccentric crankshafts after the eccentric crankshafts are placed, and the height of the upper locating plate can be adjusted by virtue of detachable upright post design, so that various eccentric crankshafts can be shared, and the product quality and the production efficiency can be improved better.
