Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing, in particular to a positioning device for PCB board processing. Background Art

[0002] PCB board is a circuit board, which is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. It is used to integrate and install various electronic components to achieve modern electrical control. During the processing of PCB board, positioning, drilling, welding and other processes are usually required.

[0003] At present, when processing PCB boards, it is usually necessary to clamp and fix the PCB boards before processing them. After the PCB boards are clamped and fixed, when processing other surfaces of the PCB boards, the personnel need to loosen the clamping tools and turn the PCB boards over again. Therefore, it is troublesome to clamp and turn the PCB boards over many times. In addition, it is inevitable that debris and dust will be generated during the processing, which are easily scattered on the operating table and diffused in the air. Utility Model Content

A first clamping plate 9 is fixedly provided at the end of the rod 3 opposite to the limiting disc 8, a hydraulic telescopic rod 10 is fixedly provided on the inner wall of the clamping device main body 1 corresponding to the first rotating rod 3, a second bearing 11 is provided at the output end of the hydraulic telescopic rod 10, and the hydraulic telescopic rod 10 is movably connected to the second clamping plate 12 through the second bearing 11, and the clamping device main body 1 is symmetrically provided with suction ports 13 at the lower ends of the first clamping plate 9 and the second clamping plate 12, a collecting frame 14 is provided on the side of the clamping device main body 1 corresponding to the suction port 13, and a dustproof net 15 is fixedly provided on the collection frame 14 corresponding to the suction port 13.

[0021] like Figure 2 As shown, a pull rod 16 is fixedly provided on the outer wall of one end of the collecting frame 14. By pulling the pull rod 16, the pull rod 16 can move together with the collecting frame 14, so as to facilitate the disassembly and assembly of the collecting frame 14. The outer wall of the turntable 5 is symmetrically welded with a handle 17. By manually holding the handle 17 and dragging it along the rotating rod 3, the turntable 5 and the limit block 4 can be moved, so that the limit block 4 can be moved out of the limit groove 6. The end of the rotating rod 3 corresponding to the first bearing 2 is cylindrical, so as to facilitate the rotation and limitation of the rotating rod 3. The outer wall of the rotating rod 3 corresponding to the limit block 4 is rectangular, the limit block 4 is in the shape of a cube, and the inside of the limit groove 6 is in the shape of a cube. The inner wall of the limit groove 6 is slidingly connected to the limit block 4, so that the rotating rod 3 can be limited by the limit block 4 cooperating with the limit groove 6.
