Clamping device for processing aluminum-based circuit board of LED lamp

Abstract

The invention discloses a clamping device for processing an aluminum-based circuit board of an LED lamp. The clamping device comprises a base plate; a telescopic rod is fixedly installed in the middle of the upper end of the base plate; a limiting rotary button is fixedly installed in the middle of the right end of the telescopic rod; a rotating device is arranged at the upper end of the telescopic rod; the rotating device comprises a limiting base, an adjusting groove, inner gear rings, insection structures, an inner edge support, a first fixing shaft, a first gear, a second fixing shaft and a second gear; the limiting base is fixedly installed at the upper end of the telescopic rod; the adjusting groove is formed in the circumferential side of the front end of the limiting base; and the inner gear rings are symmetrically installed at the upper end and the lower end in the limiting base. When the clamping device is in use, the lower inner gear ring is controlled to rotate through the adjusting groove, the lower inner gear ring and the first gear are subjected to insection meshing, and therefore the upper inner gear ring is further forced to rotate through the insection meshing of the first gear and the second gear, rotation of a clamping device body on the upper portion is completed, and machining is convenient.

Description

technical field

[0001] The invention relates to a clamping device, in particular to a clamping device for processing aluminum-based circuit boards for LED lamps. Background technique

[0002] The names of circuit boards are: circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed circuit board, etc. The circuit board makes the circuit miniaturized and intuitive It plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. The circuit board can be called a printed circuit board or a printed circuit board. The clamping device will be used in the process of circuit board processing, and the current clamping device for circuit board processing is easy to cause damage to the circuit board when it is used, the clamping effect is not good, and it cannot be used for circuits of different lengths. Only one length of c...
