小型半自动攻丝机的三维立体设计

Title    Three-dimensional design of semi-automatic tapping machine

Abstract  Tapping is an essential part of modern industrial development and machinery manufacturing.According to the working characteristics of tapping itself, in order to achieve tap tapping successfully,we must turning the tap head itself first to achieve rotation.So that when the workpiece touch the tap by external force,equipment can be work by relative motion .
According to the principle of tapping,transmission parts need to achieve the reversible function.Taps connected to the friction wheel.The friction between the drive plate is the premise of reversible,and this equipment can control the speed of tap.Reference to the relevant information and documentation,and according to the power and speed requirements,then fix the ratio of transmission.Calculate the optimum size of the parts based on a series of parameters,Select right related accessories,then check the shaft.By reference to the relevant information and documentation,here choiced related accessories,and the checking of axis ensured the accuracy and practicality of this design. 源`自<六:维;论-文>网/www.lwfree.cn
