Description
Technical Field
The utility model relates to a circuit board processing field especially relates to a circuit board drilling processing agency.
Background
The drilling of the circuit board is to drill a through hole or a blind hole on the circuit board by using a drill bit so as to copperize in the hole at the later stage to realize the conduction of an interlayer circuit. And in the drilling process, need provide firm support for the circuit board, when preventing that the drill bit from pushing down the drilling, the atress department of circuit board warp, leads to the reduction of machining precision, still can have a large amount of pieces cull to produce in addition and remain on the drilling machine, processing when influencing follow-up drilling easily.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, the utility model provides a circuit board drilling processing mechanism, including the drilling machine, be fixed in the drilling machine above the drilling machine, the drilling machine lower extreme is equipped with the chuck, centre gripping a drill bit in the chuck, the handle of a knife of chuck tightly grabs the drill bit, the handle of a knife is perpendicular to the mesa of drilling machine, the blade of drill bit faces down, be equipped with a square lumber skid on the mesa of drilling machine, the through-hole design position that corresponds the circuit board on the lumber skid is equipped with the recess of bowl form, and the recess bottom is equipped with the through-hole that runs through the lumber skid, and the through-hole position of recess bottom corresponds with the through-hole design position of circuit board; the table board of the drilling machine is further provided with L-shaped convex blocks corresponding to four corners of the skid board respectively, bent parts of the four convex blocks correspond to four corners of the skid board respectively, and the skid board is embedded between the four convex blocks.
Preferably, the aperture of the through hole at the bottom of the groove is 1.5-2 times of the diameter of the knife body.
Preferably, the diameter of the top of each groove is 2-3 times of that of the through hole of the corresponding circuit board.
The utility model discloses a design paddling board is used for filling up in the circuit board below to set up in circuit board drilling position below at the design recess, when driling the circuit board, can be in order to provide firm support below circuit board drilling position, can provide accommodation space for the piece glue sediment that produces when driling again, the recess is designed into the bowl form and can be convenient for clean, and the recess bottom designs the through-hole, can guarantee after the drill bit runs through the circuit board, can not dig into the paddling board again; and the skid plate adopts an installation mode of being embedded between the convex blocks, so that the skid plate is convenient to disassemble and replace.
Drawings

Fig. 2 is a schematic view of a backing plate of an embodiment of a circuit board drilling mechanism provided by the present invention.
Detailed Description
To facilitate understanding of the invention for those skilled in the art, the invention will be described in further detail with reference to the accompanying drawings and examples.
The circuit board drilling machining mechanism shown in the figure 1 comprises a drilling machine 1 and a drilling machine 11 fixed above the drilling machine, wherein a chuck 12 is arranged at the lower end of the drilling machine, a drill bit 2 is clamped in the chuck, a tool shank of the drill bit is tightly grabbed by the chuck, the tool shank of the drill bit is perpendicular to the table top of the drilling machine, a tool body of the drill bit faces downwards, when a hole is drilled in a circuit board 3, the drilling machine presses downwards, and the tool body of the drill bit drills the hole.
As shown in fig. 2, be equipped with a square lumber skid 4 on the mesa of drilling machine, the through-hole design position that corresponds the circuit board on the lumber skid is equipped with the recess 41 of bowl form, and the top diameter of recess is 2 times of the through-hole diameter of the circuit board that corresponds for the lumber skid can provide firm support in circuit board drilling position below, and the piece that produces when can giving drilling again glues the sediment and provides accommodation space, and the recess design becomes the bowl form can be convenient for clean.
The bottom of the groove is provided with a through hole 42 penetrating through the backing board, the position of the through hole at the bottom of the groove corresponds to the design position of the through hole of the circuit board, and the aperture of the through hole at the bottom of the groove is 2 times of the diameter of the knife body. The drill bit can be ensured not to drill into the backing board after penetrating through the circuit board.
Still correspond four angles of lumber skid on the mesa of drilling machine and be equipped with the lug 5 of L shape respectively, the bending part of four lugs corresponds four angles of lumber skid respectively, and the lumber skid imbeds between four lugs, and convenient to detach changes to adapt to different circuit board drilling requirements.
The above is a detailed description of the present invention, which is described in more detail and specific, but not intended to be construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, many variations and modifications are possible without departing from the inventive concept, and such obvious alternatives fall within the scope of the invention. The details of the present invention, which are not described in detail, can be realized by any kind of prior art.
