Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

The utility model provides a PCB drilling plate tool clamp, please refer to FIG. 1, which comprises a clamp body in L shape, wherein chamfers 8 are arranged at four corners of the clamp body to prevent operators from scratching; the clamp body comprises a bottom surface 1 which is in contact with the workbench and a pressing surface 3 which is used for pressing the plate, and a plurality of grooves 6 and observation holes 4 are uniformly formed in the pressing surface 3; the plurality of grooves 6 ensure the processing flatness and the pressing strength after contact, and the observation holes 4 are convenient for observing the pressing condition of the PCB, thereby improving the operability; the bottom surface 1 is higher than the pressing surface 3; evenly open along length direction on the bottom surface 1 has a plurality of blind hole 2, a plurality of be equipped with powerful magnet in the blind hole 2, as preferred, powerful magnet is neodymium iron boron powerful magnet.

Referring to fig. 2, a side surface 9 of the clamp body is provided with a plurality of threaded holes 7, and referring to fig. 1, a plurality of ball plungers 5 are installed in the threaded holes 7; the ball plunger 5 can apply a transverse pressing force to the processed PCB, so that the PCB is prevented from transversely shaking.

The utility model relates to a PCB board drilling panel frock clamp's theory of operation:

use the utility model provides a when supplementary drilling to the PCB board, the PCB board coincide is on the plank cushion to together place on the workstation, arrange a plurality of PCB board drilling panel frock clamp uniformly in the periphery of waiting to process PCB panel, just compact surface 3 and the laminating of PCB panel face, bottom surface 1 and table surface laminating, the powerful magnet that sets up on the bottom surface 1 can apply fore-and-aft packing force to the PCB board, horizontal clamp force is applyed to the PCB board to bulb plunger 5, prevents the horizontal drunkenness of PCB board.

The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
