The invention provides a cam grinding machine automatic positioning mechanism for an engine cam shaft and belongs to the technical field of cam shaft machining devices. The cam grinding machine automatic positioning mechanism for the engine cam shaft solves the technical problem that during grinding of an existing cam shaft, feeding and clamping are inconvenient. The cam grinding machine automaticpositioning mechanism for the engine cam shaft comprises a supporting base used for containing a cam shaft workpiece and a tail center located on one side of the supporting base; a head frame capableof rotating is arranged on the other side of the supporting base; the head frame is provided with a head center right opposite to the tail center and the head center and the tail center can move in opposite directions; the side, located on the head center, on the head frame is provided with an angle direction positioning pin which faces the tail center; and the head frame is further provided witha hydraulic spring chuck which is located on the periphery of the head center. The mechanism is high in automation degree, manual auxiliary operation is not needed for the whole action, the manual feeding time is shortened, and the feeding efficiency is high; and the action is accurate and reliable, and using is convenient and fast.
Description
technical field [0001] The invention belongs to the technical field of engine parts manufacturing equipment, and relates to camshaft processing equipment, in particular to an automatic positioning mechanism for a cam grinder of an engine camshaft. Background technique [0002] The camshaft is one of the five core components of the engine. Its function is to control the opening and closing of the valve. The cam bearing is subject to periodic impact loads. The contact stress between the cam and the tappet is very large, and the relative sliding speed is also high. Therefore, the wear of the cam working surface is serious. In view of this situation, in addition to the high dimensional accuracy, small surface roughness and sufficient rigidity, the camshaft journal and the cam working surface should also have high Wear resistance and good lubrication. Cam grinding of camshafts is the core technology and key process of the entire camshaft manufacturing process. Therefore, the mac...
