technical field

The invention relates to a chamfering equipment, in particular to an automatic chamfering equipment.

Background technique

As we all know, milling and chamfering equipment usually consists of a vibrating feeding tray and a machine tool. The vibrating feeding tray is a feeding device that is automatically oriented and sorted. Its working purpose is to automatically and orderly arrange disordered workpieces in a neat and accurate manner through vibration. In the next process, especially the arrangement of small workpieces that are difficult to operate manually, and the arrangement of ultra-small workpieces, workers usually need to supply a part of workpieces to the vibrating feeding tray at regular intervals in order to prevent the vibrating feeding tray from being blocked during operation. Make the vibrating feeding tray run more efficiently, but this method requires workers to frequently feed, which greatly increases the workload of workers.

Existing machine tools usually need to use a wrench to clamp the workpiece during the clamping process to ensure that the workpiece can be kept stable during processing. However, manual clamping of the workpiece not only increases the number of workers, but also reduces labor efficiency.
