Problems solved by technology
[0003] However, after the inner rotor of the engine oil pump in the market is cast, sand will form on the surface, and the following problems exist in the sand-out treatment of the inner rotor of the engine oil pump: a. The inner rotor of the oil pump is quickly clamped and fixed, which reduces the working efficiency of the machine when sanding the inner rotor of the engine oil pump
b. Before the inner rotors of multiple sets of engine oil pumps are clamped and fixed at the same time, the distance between the inner rotors of multiple sets of inner rotors cannot be guaranteed, resulting in poor sand cleaning effect of the inner rotors of the engine oil pump

The invention relates to a casting process for an inner rotor of an engine oil pump, which includes a workbench, a fixing device and a moving device. There is a moving device. Through the cooperation of the set workbench, fixing device and moving device, the invention firstly places the casted inner rotors of the engine oil pump on the fixing device in batches, so that when the machine performs sand cleaning on the inner rotor of the engine oil pump The work efficiency is improved. After the placement is completed, a certain distance is ensured between the inner rotor of the engine oil pump and the inner rotor through the fixing device, so that the effect of the mobile device on cleaning the inner rotor of the engine oil pump is improved.
Description
technical field [0001] The invention relates to the technical field of casting and forming of an inner rotor of an engine oil pump, in particular to a casting and forming process of an inner rotor of an engine oil pump. Background technique [0002] The rotor oil pump consists of a housing, an inner rotor, an outer rotor and a pump cover. The inner rotor is fixed on the rotor shaft with keys or pins, and is directly or indirectly driven by the crankshaft gear. The eccentric distance between the inner rotor and the outer rotor center is e, and the inner rotor drives the outer rotor to rotate in the same direction. Generally, the rotor oil pump The inner rotor has 4 or more convex teeth, and the number of concave teeth of the outer rotor is one more than the number of convex teeth of the inner rotor. The rotor type oil pump has compact structure, small size and light weight, large oil suction vacuum and large pump oil volume. , good oil supply uniformity, low cost, widely use...
