Abstract
The invention discloses an improved structure of a clamping jaw for a printed circuit board drill bit ring assembling machine. The improved structure is characterized in that the end portions of a clamping head of a drilling bit handle clamping type clamping jaw for an existing ring assembling machine extend downwards to form the clamping ends, and the opposite faces of the pair of clamping ends are in a shape matched with the peripheral face of a lantern ring so that the lantern ring on a drill bit can be directly clamped rather than the traditional mode that the drill bit drill handle portion is clamped. The improved clamping jaw is free of influences of the diameter of the drill bit and the length of a knife, the problem that the drill bit can not be clamped by the clamping head is solved, and due to the fact that the lantern ring is made of plastic materials, the situation that the clamping jaw is seriously abraded is avoided.
Description
Technical field
The present invention relates to a kind of ring assembling machine for printed circuit board drill parts, relate in particular to the structure-improved of jaw for a kind of ring assembling machine for printed circuit board drill.
Background technology
In the boring processing procedure of printed circuit board (pcb); during boring for fear of the printed circuit and the electronic component that damage on circuit board; and for guaranteeing that drilling depth reaches necessary requirement; conventionally can there is at the drillstock position sheathed of printed circuit board target drill the collar (as shown in Figure 1) of protective effect; at present the general PCB drill point collar all adopts plastic material to make on the market; and this collar external diameter is unified value, the common 7.6mm that is generally.The operation of the sheathed collar adopts pressed on ring machine to complete conventionally, but because the collar bottom surface of different-diameter drill bit to the distance of apex point is a fixed value, and simple collar operation can not accurately reach this value, therefore after completing collar operation, still need the PCB drill point of the sheathed good collar to carry out depth compensation, can precisely reach desirable value.The above-mentioned process of the PCB drill point of the sheathed good collar being transferred to depth compensation station, still needs to adopt the clamping of pressed on ring machine jaw to realize.
The jaw of ring assembling machine for printed circuit board drill is generally stick of tool pin drillstock formula jaw at present, and the jaw chuck of this kind of structure is two metal fixture blocks that are oppositely arranged, and this two metals fixture block opposite face is planar structure (as shown in Figure 2).But because drill point body 4 cuttves of used for printed circuit board minor diameter drill point (as 1.25-1.50mm diameter drill point) are long oversize; the distance shorter (as shown in Figure 1) of the drillstock 2 between drillstock tapering 3 and the collar 1; cause the collet segment of jaw cannot firmly grasp drill point, thus the situation that makes pressed on ring machine often there will be shutdown or drill bit to drop in operation process.In addition, stick of tool pin drillstock formula jaw clamps drill point drillstock at every turn, and drill point drillstock is metal material, comparatively serious to the chuck wearing and tearing of jaw, also easily cause clamping not strongly admittedly, thus the service life of shortening jaw.
Summary of the invention
In order to overcome above-mentioned technological deficiency, the invention provides the structure-improved of jaw for a kind of ring assembling machine for printed circuit board drill, the jaw that the jaw improvement at the clamping drill point drillstock position that this structure adopts traditional pressed on ring machine is the clamping drill point collar, has avoided drill point to drop and the situation of jaw serious wear.
The present invention in order to solve the problems of the technologies described above adopted technical scheme is:
The structure-improved of jaw for a kind of ring assembling machine for printed circuit board drill, comprise the first jaw and second jaw that can carry out clamping relatively, the end of this first jaw is provided with the first chuck, the end of this second jaw is provided with the second chuck, described first and second chuck is the fixture block being oppositely arranged, the end of described the first chuck extends to form the first bare terminal end downwards, the end of described the second chuck extends to form the second bare terminal end downwards, and the relative one side of this first and second bare terminal end is the shape of mating with collar outer peripheral face.
Its further technical scheme is:
The fixture block that described the first chuck is L-shaped structure, described the second chuck is to be the fixture block of mirror image symmetry with the first chuck.
Described the first bare terminal end is extended to form downwards by the base of the first chuck " L " shape structure fixture block, and described the second bare terminal end is extended to form downwards by the second chuck and the base of the symmetrical fixture block of " L " shape structure mirror image.
The relative one side of described first and second bare terminal end is all concave arcuate structure.
The length of described first and second bare terminal end is 3.5-4.0mm.
The length of described first and second bare terminal end is 3.75mm.
Useful technique effect of the present invention is: this structure-improved extends to form bare terminal end downwards by the chuck end of existing pressed on ring machine stick of tool pin used handle-type jaw, and a pair of bare terminal end relatively one side is the shape of mating with collar outer peripheral face, to can directly clamp the collar on drill point but not clamp drill point drillstock position in traditional approach, jaw after improvement is not subject to drill point diameter and the long impact of cutter, can avoid occurring that chuck can not press from both sides the problem of drill point, and because of the collar, by plastic material, prepared, avoided the situation of jaw serious wear.

The specific embodiment
In conjunction with Fig. 1 to Fig. 3, the present invention is described in further detail.
The structure-improved of jaw for a kind of ring assembling machine for printed circuit board drill, comprise the first jaw 5 and second jaw 6 that can carry out clamping relatively, the end of this first jaw is provided with the first chuck 7, the end of this second jaw is provided with the second chuck 8, described first and second chuck is the fixture block being oppositely arranged, the end of described the first chuck 7 extends to form the first bare terminal end 9 downwards, the end of described the second chuck 8 extends to form the second bare terminal end 10 downwards, and the relative one side of this first and second bare terminal end is the shape of mating with the collar 1 outer peripheral face.The fixture block that wherein said the first chuck 7 is L-shaped structure, described the second chuck 8 is to be the fixture block of mirror image symmetry with the first chuck.Described the first bare terminal end 9 is extended to form downwards by the base of the first chuck 7 " L " shape structure fixture block, and described the second bare terminal end 10 is extended to form downwards by the second chuck 8 and the base of the symmetrical fixture block of " L " shape structure mirror image.The relative one side of described first and second bare terminal end is all concave arcuate structure.The length of described first and second bare terminal end 9,10 is 3.5-4.0mm, and optimization length is 3.75mm.
