In the present embodiment, as shown in fig. 1, 3 and 4, the first clamping bar 2 is positioned above the second clamping bar 3. In order to make the upper surfaces of the two first long-side protrusions 21 and the upper surfaces of the two second long-side protrusions 31 be in the same plane, as shown in fig. 3 and 4, the first long-side protrusions 21 located on either side of the first clamping bar 2 are respectively located at both ends of the first clamping bar 2 along the length direction of the first clamping bar 2.

Therefore, in practical applications, the first clamping bar 2 can slide along the length direction of the third side 13 and the fourth side 14 by means of the sliding fit of the two second protrusions 22 with the third sliding slot 131 and the fourth sliding slot 141, respectively.
In addition, in order to ensure the stability of the first clamping rod 2 and the second clamping rod 3 when any two sides of the first side 11, the second side 12, the third side 13 and the fourth side 14 of the frame body 1 are clamped on the PCB. As shown in fig. 1, 4 and 6, in the present embodiment, the upper surface of the first side 11 is opened with a first waist-shaped groove 112 communicating with the first slide groove 111 along the sliding direction of the first clamping bar 2, the upper surface of the second side 12 is opened with a second waist-shaped groove 122 communicating with the second slide groove 121 along the sliding direction of the first clamping bar 2, the upper surface of the third side 13 is opened with a third waist-shaped groove 132 communicating with the third slide groove 131 along the sliding direction of the second clamping bar 3, and the upper surface of the fourth side 14 is opened with a fourth waist-shaped groove 142 communicating with the fourth slide groove 141 along the sliding direction of the second clamping bar 3. Meanwhile, as shown in fig. 4, 5 and 6, the jig of the present embodiment further includes: a first locking member 5 for locking the first side 11 and one of the first protrusions 22 of the first gripping shank 2, a second locking member 6 for locking the second side 12 and the other of the first protrusions 22 of the first gripping shank 2, a third locking member 7 for locking the third side 13 and one of the second protrusions 32 of the second gripping shank 3, and a fourth locking member 8 for locking the fourth side 14 and the other of the second protrusions 32 of the second gripping shank 3. In the present embodiment, the first locking member 5, the second locking member 6, the third locking member 7, and the fourth locking member 8 have the same structure, specifically, as follows:
as shown in fig. 4 and 5, wherein the first locking member 5 includes: the first threaded section 51 is slidably disposed in the first waist-shaped groove 112, and the first cap 52 is coaxially fixed with the first threaded section 51, and the first cap 52 is exposed on the upper surface of the first side 11. The second locking member 6 includes: the second threaded segment 61 is slidably disposed in the second waist-shaped groove 122, and the second cap 62 is coaxially fixed to the second threaded segment 61, and the second cap 62 is exposed on the upper surface of the second side edge 12. In practical applications, after the first clamping rod 2 finishes clamping the PCB, the first threaded section 51 of the first locking member 5 may be directly in threaded connection with one of the first protrusions 22 of the first clamping rod 2 until the first cap 52 is snapped on the upper surface of the first side 11, and the second threaded section 61 of the second locking member 6 may be directly in threaded connection with the other first protrusion 22 of the first clamping rod 2 until the second cap 62 is snapped on the upper surface of the second side 12, so that the first clamping rod 2 can be stably fixed in the frame 1.
Similarly, as shown in fig. 6, in the present embodiment, the third locking member 7 includes: a third threaded segment 71 slidably disposed in the third waist-shaped groove 132, and a third cap 72 coaxially fixed with the third threaded segment 71, wherein the third cap 72 is exposed on the upper surface of the third side 13. And a fourth locking member 8 including: a fourth thread segment 81 slidably disposed in the fourth waist-shaped groove 142, and a fourth cap 82 coaxially fixed with the fourth thread segment 81, wherein the fourth cap 82 is exposed on the upper surface of the fourth side 14. In practical applications, after the second clamping bar 3 finishes clamping the PCB, the third threaded section 71 of the third locking member 7 may be directly threaded with one of the second protrusions 32 of the second clamping bar 3 until the third cap 72 is snapped onto the upper surface of the third side 13. The fourth thread 81 of the fourth locking member 8 is directly screwed with the second protrusion 32 of the second clamping bar 3 until the fourth cap 82 bites the upper surface of the fourth side 14, so that the second clamping bar 3 can be stably fixed in the frame 1.
It can be seen from the above that, since the first clamping bar 2 is fixed in the frame body 1 by means of the first locking member 5 and the second locking member 6 being respectively screwed to the first protrusions 22 at both ends of the first clamping bar 2, and the second clamping bar 2 is fixed in the frame body 1 by means of the third locking member 7 and the fourth locking member 8 being respectively screwed to the second protrusions 32 at both ends of the second clamping bar 3. Therefore, the two first protrusions 22 may be pre-formed with the first screw holes 221, and the two second protrusions 32 may be pre-formed with the second screw holes 231.
Also, it is preferable to facilitate the screw coupling of the first and second screw segments 51 and 61 with the two first protrusions 22, respectively, and to facilitate the screw coupling of the third and fourth screw segments 71 and 81 with the two second protrusions 32, respectively. In the present embodiment, the first cap 52, the second cap 62, the third cap 72 and the fourth cap 82 are knobs with knurls, so that the friction force between the hands of the worker and the caps can be increased when the workers rotate the locking pieces, and the workers can operate the locking pieces more conveniently.
In addition, in the present embodiment, the first side 11, the second side 12, the third side 13 and the fourth side 14 are detachably connected, for example, locked and fixed by screws, so that after the first side 11, the second side 12, the third side 13 and the fourth side 14 are completely detached, the first clamping rod 2 and the second clamping rod 3 can be conveniently installed and replaced.
The utility model discloses a second embodiment relates to a PCB board clamping jig for welding, and the second embodiment is further improved on the basis of first embodiment, and its main improvement lies in: in the present embodiment, as shown in fig. 6 and 7, the first clamping bar 2 is provided with a first elastic layer 91 on the side opposite to the third side 13 and the fourth side 14, and the second clamping bar 3 is provided with a second elastic layer 91 on the side opposite to the first side 11 and the second side 12. In the present embodiment, the first elastic layer 91 and the second elastic layer 92 are both rubber layers or silicone layers.
It can be seen from the above that, by means of the first elastic layer 91 disposed on the first clamping rod 2 and the second elastic layer 92 disposed on the second clamping rod 3, when the first clamping rod 2 and the second clamping rod 3 clamp the PCB 4 in the matching frame 1, they are in flexible contact with the PCB 4, rather than in hard contact, so as to play a role in buffering the PCB during clamping, and further avoid the phenomenon of breaking or breaking of the PCB 4 due to too large clamping force.
It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
