Abstract

The utility model discloses a shearing wrench for a PCB. The shearing wrench for the PCB comprises a handle and a wrench head arranged at one end of the handle, the wrench head comprises a lower L-shaped clamping plate and an upper L-shaped clamping plate, the lower L-shaped clamping plate and the upper L-shaped clamping plate respectively comprise a side face and a bottom face, an opening of the lower L-shaped clamping plate is opposite to an opening of the upper L-shaped clamping plate, the side face of the lower L-shaped clamping plate and the side face of the upper L-shaped clamping plate are arranged in parallel, the bottom face of the lower L-shaped clamping plate and the bottom face of the upper L-shaped clamping plate are overlapped and are fixedly connected, and the lower L-shaped clamping plate and the upper L-shaped clamping plate form a groove. Through the design, the edge of the PCB to be sheared can be clamped in the groove, the wrench handle is wrenched upwards or downwards, the PCB to be sheared can be bent and sheared, due to the fact that the wrench head clamps the PCB to be sheared through the groove, the contact area of the groove is large, in the bending and shearing process, a local breaking phenomenon cannot occur to the PCB to be sheared, and the edge of the sheared PCB is in order.

Description

A kind of spanner of the pruning for pcb board

Technical field

The utility model relates to the process equipment of pcb board, a kind of spanner of the pruning for pcb board of specific design.

Background technology

In the electronic product production technical field, pcb board is sheared out shape and profile roughly through the substrate cutter before electronic devices and components are installed, install after electronic devices and components need to around substrate not installation region pruned.During pruning, can adopt the substrate cutter to prune, also can adopt artificial pruning.Due to electronic devices and components being installed on pcb board, adopt the substrate cutter to prune inconvenient clamping, and cost is high; And adopt while manually pruning, the general using hand vice are clamped pcb board to be pruned, then by the application of force pcb board to be pruned that clamps to fracture, adopt this mode to prune pcb board, although cost is low, because the contact site area of the jaw clamped and PCB plate is less, in Forging Process, pcb board to be pruned there will be the part phenomenon that fractures, and causes the edge of PCB plate to there will be coarse and irregular.

The utility model content

The purpose of this utility model is to overcome in prior art prunes pcb board and there will be the part phenomenon that fractures, and causes the edge of PCB plate to there will be coarse and irregular defect, provides a kind of rational in infrastructure, the spanner of the pruning for pcb board of trimmed.

For achieving the above object, the technical solution of the utility model provides a kind of spanner of the pruning for pcb board, comprise handle and the driving end that is arranged on handle one end, described driving end comprises under L-type clamp on clamp and L-type, under described L-type on clamp and L-type clamp comprise respectively a side and a bottom surface, under L-type, clamp is relative with clamp opening on L-type, keeping parallelism setting in clamp side on clamp side and L-type under L-type, under L-type, the clamp bottom surface is overlapping with clamp bottom surface on L-type and be fixedly connected with, under L-type on clamp and L-type clamp form a groove.By above design, can snap in described groove holding the edge of pruning the PCB plate, pull up or down spanner handle, the PCB plate bending of holding pruning can be cut off, because driving end clamps PCB plate to be pruned by groove, the groove contact area is large, when bending is pruned, PCB plate to be pruned not there will be the part phenomenon that fractures, and the edge of the PCB plate after pruning is neat.

As preferably, under described L-type, the clamp bottom surface is provided with fixing hole, described fixing hole arranges in pairs, the fixing hole line of centres is parallel with clamp two sides intersecting straight lines under L-type, described paired fixing hole is provided with multirow, the fixing hole that on described L-type, the clamp bottom surface is provided with under L-type, clamp bottom surface fixing hole coordinates.Width that can adjusting grooves like this, adapt to the needs that the different-thickness pcb board is pruned.

As preferably, the paired fixing hole of described multirow equidistantly arranges.Such design can be so that the variation of recess width be more even, and the pcb board that makes the pruning spanner of pcb board to prune is wider.

As preferably, along the inboard both sides of the openend of described groove, be provided with cutting edge.Such design can be so that the pruning process be more light, the fracture that makes cut pcb board be more prone to due to the effect of cutting edge, and fracture is more neat.

Advantage of the present utility model and beneficial effect are: by above design, can snap in described groove holding the edge of pruning pcb board, pull up or down spanner handle, the PCB plate bending of holding pruning can be cut off, because driving end clamps pcb board to be pruned by groove, the groove contact area is large, when bending is pruned, pcb board to be pruned not there will be the part phenomenon that fractures, and the edge of the PCB plate after pruning is neat.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation that under the utility model L-type, clamp is connected with clamp on L-type;

In figure: 1, handle; 2, driving end; 3, clamp on L-type; 4, clamp under L-type; 5, side; 6, bottom surface; 7, cutting edge; 8, fixing hole; 9, bolt; 10, groove; .

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.

As depicted in figs. 1 and 2, a kind of spanner of the pruning for pcb board, comprise handle 1 and the driving end 2 that is arranged on handle 1 one ends, described driving end 2 comprises under L-type clamp 3 on clamp 4 and L-type, under described L-type on clamp 4 and L-type clamp 3 comprise respectively a side 5 and a bottom surface 6, under L-type, clamp 4 is relative with 3 openings of clamp on L-type, clamp 3 side 5 keeping parallelism settings on clamp 4 sides 5 and L-type under L-type, under L-type at the bottom of clamp 4 overlapping with 3 bottom surfaces 6 of clamp on L-type and be fixedly connected with, under L-type on clamp 4 and L-type clamp 3 form a groove 10.

Under described L-type, clamp 4 bottom surfaces 6 are provided with fixing hole 8, described fixing hole 8 arranges in pairs, fixing hole 8 lines of centres are parallel with the 4 two sides intersecting straight lines of clamp under L-type, described paired fixing hole 8 is provided with multirow, and on described L-type, clamp 3 bottom surfaces 6 are provided with the fixing hole 8 coordinated with 4 bottom surface 6 fixing holes 8 of clamp under L-type.

The paired fixing hole 8 of described multirow equidistantly arranges.

Be provided with cutting edge 7 along the inboard both sides of the openend of described groove 10.

In practical operation, pcb board is snapped in groove 10, pull up or down handle 1, can neat the cutting off by the pcb board of holding pruning under the effect of cutting edge 7, if the width of groove 10 and the thickness of pcb board are inconsistent, can adjust the position relationship that under L-type, on clamp 4 and L-type, on clamp 3, fixing hole 8 overlaps, adjust wide or adjust the width of narrow groove 10, then fixing with bolt 9, repeat aforesaid operations.

The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
