3M7680 Type Steel Ball Grinding Machine Optimization Design Research

Based on the "12th Five-Year Plan" the development needs of the bearing industry, the production process in the study, based on the ball, the ball of light used to process the ball milling machine 3M7680 steel structure and processing principles in-depth study, based on actual production activity in the presence of defects and shortcomings, targeted for 3M7680 steel ball milling machine structure is optimized to improve the precision steel balls and the processing efficiency at the same time achieve the purpose of energy saving. Paper mainly on the following aspects of the optimization study: 1. spindle system as the core power system, to improve system efficiency, the direct use of the spindle and the flexible shaft coupling gear motor is connected, and because the flexible pin coupling can compensate for the spindle and the motor shaft axis between the different installation error trace the system is also available to ensure the accuracy.2. After optimization of the machine screw nut and the use of spring mechanism to form a new mechanical feed system, and the damping plate in the form of a modular organization to the new machine installed in order to ensure system stability, to give up the original models rotating disk feed form, and the fixed disk to install the line of rail. This installation will help ensure the stability of the spindle rotation to prevent the disc jitter caused by the spindle rotation, thereby affecting the machining accuracy. 3. goals in the mouth feed system will be more than one way to score raceway to a single goal, the ball in the mouth will be more than one way to roll the ball tells the roll revealed a single ball, the ball is outside the disc into the next raceway cycle, so there is no blockage of the phenomenon. Feeding method to solve the original feed for a long time, feed efficiency is low, high energy consumption problem.Through this research, and ultimately to improve the precision steel balls and the purpose of processing efficiency, and achieve the purpose of energy saving ball machine.
