Background technology
At present, in existing design frock technology, it is envisaged that whether pcb board still exists under the support of frock becoming
Shape.After high temperature, even if the pcb board that size is bigger than normal or weight is bigger than normal still has deformation slightly under the support of frock.
1) using existing PCB through high-temperature soldering when the frock clamp that used be technical basis, studied, frock is pressed from both sides
Tool plays certain supporting role in welding process, but due to pb-free solder temperature drift, still some Light deformation after welding；
2) when crossing high-temperature soldering using existing frock clamp, if pcb board is long, even with frock clamp, deform
Still serious；
The deformation of pcb board be substantially middle bend downwards, both sides upwards, for this phenomenon, the utility model proposes setting
Meter thinking：Hold the both sides of pcb board using a kind of instrument supporting upwards, withstood in pcb board with the instrument of a downward support
Between, held up upwards by the both sides that outside reinforcing makes pcb board, through reinforcing after a while so that the deformation of pcb board
Reduce.

Preferably, described pcb board shaping tool it is characterised in that：Support frame as described above is set to inverted "L" shaped knot
Structure, threadeded with locking nut in bracing frame upper end, bracing frame bottom is provided with the chuck structure for fixing pcb board.
Beneficial effect：A kind of pcb board shaping tool that this utility model provides, PCB shaping tool can be deformed slightly
Reduction；Warpage can be reduced in the case of temperature residual by PCB shaping tool in time.Frock is by carrying out to whole pcb board
Support, the support force of pcb board is strengthened, whole pcb board is held up by frock, when standing high temperature by strong support
Reduce the power of influence to deformation for the gravity.Design is unique, is adjustably controlled the distance between strong point by locking nut, conveniently looks for
To the suitable strong point, the layout of pcb board is no excessively required.This utility model volume ratio pcb board is smaller, easy to carry, knot
Structure is simple, easy to operate.
Brief description
Fig. 1 is structural representation of the present utility model；
In figure：Fixture 1, bracing frame 2, connecting rod 3, bull stick 4, screw rod 5, locking nut 6, stop nut 7, pcb board 8, card
Platform structure 9.
Specific embodiment
With reference to specific embodiment, this utility model is further described.
As shown in figure 1, a kind of pcb board shaping tool, including fixture 1, bracing frame 2, connecting rod 3, bull stick 4, screw rod 5, lock
Jack panel 6 and stop nut 7；
Wherein, fixture 1 is used for clamping pcb board 8, and bracing frame 2 is used for fixing pcb board.
Connecting rod 3 two ends connect bracing frame 2 by locking nut 6 respectively, and locking nut 6 is used for adjusting bracing frame 2 and connecting
The distance between extension bar 3 is so as to disclosure satisfy that the pcb board of different length.Rotational lock nut adjusts bracing frame two ends distance, uses
To fix pcb board.
Connecting rod 3 center vertical arranges screw rod 5, the bottom jockey 1 of screw rod 5, and screw rod 5 is additionally provided with stop nut
7, move along screw rod above-below direction for limiting fixture, other directions refuse to limit.
The top setting of described screw rod 5 is easy to rotate the bull stick 4 of screw rod, and this shaping tool mainly passes through rotation bull stick 4 to be made
Screw rod produces the displacement of vertical direction thus producing pulling force, and then reaches the purpose of shaping.
In the present embodiment, described connecting rod center vertical direction offers the female thread matching with the external screw thread of screw rod
Hole, described connecting rod is connected with screw flight, and produces the displacement of vertical direction by rotary screw.
In the present embodiment, described bull stick 4 is latch structure, and the upper level direction of described screw rod opens up a through hole, bull stick 4
