Description

Technical Field

[0001] The invention belongs to the technical field of switch processing, and specifically discloses a hole opening device and method for switch processing. Background Art

[0002] The principle of the switch is that the "closed" contact means that the electronic contact is conductive, allowing current to flow; "open" means that the electronic contact is not conductive, forming an open circuit, and does not allow current to flow. It is composed of structures such as a panel, a switch current-carrying part, a switch contact, a switch nozzle, and a base. According to the purpose, it can be divided into wave switches, band switches, recording and playback switches, power switches, preselection switches, limit switches, etc. According to the structure, it can be divided into micro switches, rocker switches, button switches, toggle switches, etc. During the production process of the switch, for the subsequent assembly and installation, holes are generally drilled when the switch shell is produced; In the past, the hole-punching devices used for switch processing were all universal hole-punching devices. During the hole-punching process, the hole-punching work could only be simply drilled from top to bottom. When the hole-punching position of the switch housing needed to be adjusted, the operator had to adjust it manually. In addition, since there was a certain height difference between the hole-punching device and the switch, it was difficult for the workers to confirm the hole-punching position of the switch, resulting in low hole-punching efficiency and easy deviation of the hole position.
