Abstract

The invention discloses a gear switch pin rotating device and a pin rotating machining method, and belongs to the field of pin machining equipment. The device comprises a bottom plate, a pin rotating unit and a driving unit. The pin rotating unit comprises a workpiece mounting plate, rotating feet, driving pull rods, and a bottom mounting block. A mounting groove is formed in the workpiece mounting plate, and a plurality of receding holes are formed in the mounting groove in a penetrating mode; the rotating feet are correspondingly arranged below the receding holes, assembling holes are formed in the top faces of the rotating feet, and transmission rods are formed on the side faces of the rotating feet; the driving pull rods are horizontally arranged on the two sides of the rotating feet, mounting positions are arranged on the driving pull rods, and the mounting position of each driving pull rod is in transmission connection with the corresponding column of transmission rods; and the bottom mounting block is arranged below the rotating feet, and the bottoms of the rotating feet are rotationally connected with the bottom mounting block. The driving unit is in transmission connection with the driving pull rods and provides driving force for the driving pull rods to move in the length direction. Through all structures of the pin rotating unit, under the driving of the driving unit, all pins of the gear switch can be subjected to unified rotating machining, the machining efficiency is high, pin rotating is consistent, and the machining quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of pin processing equipment, and more specifically relates to a gear switch swivel device and a swivel processing method. Background technique [0002] The heat gun is one of the tools commonly used for repairing circuit boards such as mobile phones. It is mainly used to heat and desolder the components on the PCB circuit board for replacement. Different circuit boards and different solders have different temperature requirements, so The heat gun needs to be equipped with a thermostat switch to control the heating temperature range, and a gear switch is required to realize this function. [0003] Not only heat guns, but also gear switches are used to adjust the gears of many equipments. The number of gears of the gear switches often determines the performance and price of the corresponding equipment; there are many kinds of gear switches, such as Two gears with four legs, three gears with six legs, four gea...
