LOT NUMBER MARKING DEVICE OF CAM SHAFT AND MARKING MATHOD THEREOF

摘要

The present invention relates to a method using steering angle of the camshaft and this lot number embossing device, the object is locked There pinhole cam shaft and keyways are machined parts to the lot number on the wrench automatically marked by embossing method provides a camshaft lot number embossing device and it is provided to the date of manufacture. This frame has been idle units to stop on both sides of the semi-finished state in which the camshaft fed sequentially by a conveyor installation and, disposed between the idle unit, and the elevating cylinder to rise to a certain height axis stationary cam, the elevating before the children of the unit so as to support the cam shaft center hole is raised by the amount of cylinder, and the supporting and rotating means installed in the rear center, detects the position of the camshaft keyway is rotated at an angle by the center support and rotation means and a sensor which, consisting of a marking machine will been installed on the upper side of the idle unit to mark the lot number on the camshaft spanner part upper surface is stopped by the sensor. In addition, the lot number and then supplying the camshaft camshaft embossing device of the semi-finished product in the idle state of the units installed on the frame, and the step of rising to a predetermined height by the cam shaft is stopped by the idle unit elevating cylinder, wherein W comprising the steps of: supporting and rotating means supported by the sender to the camshaft center hole is raised by the amount of lowering cylinder, the method comprising: detecting the key-way of the camshaft is rotated at a predetermined angle position by the center support and rotating means to the sensor, is composed of a lot number marking machine comprising a marking on the top surface of the camshaft spanner unit is stopped by the sensor.
