Vibration grinding machine based on double-machine coaxial self synchronism and parameter determining method

Abstract

The invention belongs to the technical field of vibration grinding devices, and discloses a vibration grinding machine based on double-machine coaxial self synchronism. The vibration grinding machine comprises an upper exciter, a vibration groove, a lining, a spring, a lower exciter, a base and a discharging port. The upper exciter and the lower exciter which are composed of motor drive eccentric rotors are coaxially arranged, the upper exciter is arranged above the vibration groove, the lower exciter is arranged below the vibration groove, and the upper exciter and the lower exciter are fixedly connected with the vibration groove. Double-machine drive is adopted, and the problem of maximization of the vibration grinding machine is solved. On the basis of the double-machine coaxial drive self-synchronism principle, through establishing of a dynamics model and a mechanical model and deduction of synchronism conditions and stable conditions, the system stable point self-adaption function can be automatically achieved according to the amount of to-be-ground materials in the system, unloading can be achieved without shutdown, and the automatic function of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of vibration grinding devices, and relates to a vibration grinding machine based on double-machine coaxial self-synchronization. Background technique [0002] Vibration grinding machine, also known as vibration finishing machine, is used for polishing, derusting, deburring or surface treatment of some raw materials for small and medium-sized workpieces. It has a large single processing capacity, simple operation, high degree of automation, and processing without destroying the original size. advantages of shape. The longer the time of single vibration grinding, the larger the capacity of the vibration grinding machine, the higher the efficiency and the better the economy. The invention belongs to a large vibration grinding machine among vibration grinding machines. Ordinary large-scale vibratory grinders have the same principle as small-scale vibratory grinders, and they are driven by a single machine, and...

AI Technical Summary

Problems solved by technology

[0007] Aiming at problems such as the use of high-power exciters, low energy utilization rate, and the need to stop for unloading in ordinary large-scale vibrating grinders, the present invention adopts the theory that two coaxially arranged exciters move synchronously under different gyration radii. Design a large vibrating grinder so that the large vibrating motor is driven by two small exciters, which not only improves production efficiency but also improves energy utilization, and also ensures that the vibrating grinder does not stop and unloads materials, which improves the automation of the vibrating finishing machine
