The balls 25 at the proximal ends of these pins 25,26 when each cam groove 41,42 of 5 faces each spring-operated pin 25,26.
Δ etc. fall into each cam groove 41 and 42, and 1■ power arm body 3
5 is stopped. In such a state, the compressive force on the clamp spring 23.24 is removed and the clamp spring 23.24 stretches, reducing the clamping force and leaving only the clamping force exerted by the clamp auxiliary spring 22. In this state,
When the metal conductor 64, 65 to be brazed is pushed between the tapered groove 16, 17 or 18 for conductor insertion and the tapered surface 19° 20 of both clamp tools 1, 2, the clamp auxiliary spring 22
Since the clamping force is weak, the insertion force of the gold aS body 64.6-5 pushes open the 1"1Ml lances 3A-5AM, 4A, and 6A, and the metal conductor 64.65 is inserted into the conductor insertion vortex 13. It can be inserted into ゜14 or 15 and protruded from the opposite side.Adjustment of the protrusion is easy as the metal conductors 64 and 65 are only lightly clamped temporarily so that they can be inserted and removed with one hand. The tips of the metal conductors 64.g5 inserted from both sides are made to face each other, and the silver brazing material 66 is interposed between them.At this time, both metal conductors 64.g5 are inserted.
The centering U-bin 21 is used to prevent the axis of the shaft 65 from shifting. When the matching operation is completed, press the operation lever 3.
Turn 7 in one direction counterclockwise as shown in Figure 2. As a result, the movable cam body 356 is rotated in the same direction, and in the process, each spring operation pin 25.26 is pushed out from each cam 1441.42 and rides on the outer periphery of the III movable cam body 39.40, and these spring operation As the pins 35 and 26 rise, the clamp springs 23 and 24 are compressed to increase the clamping force, and the metal conductors 64 and 65 are finally clamped. Even after the main clamping state is reached, the cam surface 71 of the movable cam body 35 can be rotated further by turning the operating lever 37 in one direction counterclockwise as shown in FIG.
The convex surface portion 43A of the movable cam body 35 fits into the concave surface portion 44B of the cam surface 44 of the fixed cam body 36, and the movable cam body 35 moves to the right in FIG. As the metal conductors 64 and 65 move in the direction of the silver brazing material 6, the distance between the lamp tools 1 and 2 becomes narrower.
6 is strongly pressed.

From this state, when the operating lever 37 is further turned counterclockwise in FIG. A current flows through both metal conductors 64 and 65 through 3 and 4, the silver brazing material 66 is melted, and both metal conductors 64 and 65 are connected by brazing. Electricity to the metal conductors 64, 65 is cut off after a predetermined time by a timer (not shown).

After brazing is completed, turn the operating lever 37 clockwise as shown in Figure 2. Then, the convex surface portion 43A of the cam surface 43 of the 1-cho power arm body 35 becomes the convex surface portion 4 of the cam surface 44 of the fixed cam body 36.
4A, the movable clamping tool 1 moves together with the movable cam body 35 in a direction away from the fixed clamping tool 2, the distance between both clamping tools 1.2 widens, and then the spring-operated pin 25. 26 falls into the cam groove 4.1.4.2,
Both clamp tools 1 and 2 are in a temporary clamp state. When this state is reached, the two brazed metal conductors 64, 65 are removed from the two clamps 1.2. In addition, both clamp tools 1
．． When the interval 2 is reached, each clamp tool 1, 2 is in the final clamp state, so a force is applied to both metal conductors 64, 65 in the direction of separating them, but the actual ramp force is about 3.5 kg, If the brazing is complete, the clamps 1.2 will slide open on each of the metal conductors 6/I, 65, since they will not break if pulled with such force. Therefore, it has now been inspected whether the brazed numbered portion is complete or not. .

The distance between the two lamp tools 1 and 2 can be adjusted by a clamp tool movement stroke adjustment mechanism 56. That is, when the adjustment lever 60 is turned until it hits the stopper 63, the threaded cylinder 58 is screwed together with the adjustment screws 59, and the adjustment screws 59
Push the movable cam body 35 with the tip of the lamp to widen the gap between the two lamp fittings 1 and 2. Reverse the adjustment lever 60 and turn the stopper 62
When it is turned until it hits , the threaded cylinder 58 moves back together with the adjustment screw 59, and the gap between both clamping tools 1.2 narrows.

When the metal conductor 64.65 is thick, both clamp tools 1.2
Widen the space between them, and narrow it when it is thin.

In this type of metal conductor butt brazing, it is necessary to supply silver brazing filler metal 66 to the required size between the opposing ends of both metal conductors 64 and 65, but conventionally, an appropriate brazing filler metal supply device is used. was not proposed.

Unable to resist the moment of force based on gravity acting on the tip side of the silver solder material 66, the silver solder material 66 is fused at a position close to the platinum metal conductor 64 and 65. As a result, the brazing material feeding device 6
7 is rotated clockwise in FIG. 12 by its own weight around the pivot screw 96, and the rear end 98A of the cam follower 98 falls into the cam groove 99.

As described above, the energization of the platinum metal conductors 64 and 65 is interrupted after a predetermined time by a timer (not shown).

When the operation lever 37 is turned clockwise in FIG. 2 after brazing is completed, the convex surface 43A of the cam surface 43 of the movable cam rest 35
rides on the convex surface 44A of the cam surface 44 of the fixed cam rest 36, and the movable clamp 1 moves away from the fixed clamp 2 together with the movable cam rest 35, and then the spring operated pin 25. 26 falls into the cam grooves 41, 42, and both clamping tools 1.2 become temporarily clamped.

Note that the movable cam body that controls the cam follower 98 is not limited to the above-mentioned example, and for example, another movable cam body that is interlocked with the movable cam body 35 may be used.

(Effects of the Invention) As explained above, the brazing material supply device for metal conductor butt brazing wire according to the present invention can supply and position the brazing material to both metal conductors to be butt brazed. In particular, positioning can be performed automatically by operating the movable cam body, which is very convenient in handling. In addition, in the device of the present invention, the moment of force based on gravity acting on both sides of the frame is unbalanced, and since this device also serves as a brazing material fusing device, the brazing material can also be melted. Using this device, brazing can be done quickly and with the appropriate amount of brazing.
