Abstract
Shaft parts of the machine parts are often encountered in a typical one. It is mainly used to support transmission parts, transmission torque and load to bear. Rotating shaft parts is parts, and its length is greater than diameter, generally cylindrical shaft concentric cylindrical, conical surface, and hole and thread the end of the corresponding component. According to the structural shape of different parts can be divided into the optical axis shaft, stepped shaft, hollow shaft and the crankshaft and so on. Processing procedures in the shaft, the drilling process is also one of the most important. No matter, the processing is to keep out the follow-up hole, reaming, grinding so that all the drilling projects as the first. Processing, therefore the success or failure of follow-up and smooth it or not, and the results of drilling is related breeze. Drilling work in the general machine tools, such as: drilling machines, milling machines, machining centers. However, the use of machine tools in general in the mass production of the drilling work, efficiency and speed of change is very low. So now the market is relatively common spindle drill head / drill power drill head. Therefore, the drill hole axis fixture design is necessary. Keywords: Fixture assembly processing
