Detailed description of the invention
In below describing, using the both sides at two lead-in wire locating piece 3 places as front and back both sides, using the side at backboard 2 place as left side.
(embodiment 1)
Seeing Fig. 1 and Fig. 2, the lead-in wire welding tooling of the capacitor of the present embodiment includes base 1, backboard 2, lead-in wire locating piece 3, fuse locating rack 4, auxiliary positioning bolt 6 and positive stop 7.
The plate of base 1 generally one piece of cuboid, is supported on work top by the installation foot 11 of lower section.
Backboard 2 is vertical with base 1, bolt 21 be fixed in the left side of base 1.The lower surface of the lower surface of backboard 2 and base 1 is at grade；At grade, the rear end face of the rear end face of backboard 2 and base 1 is at grade for the front end face of the front end face of backboard 2 and base 1.The top of backboard 2 offers two for the screw 22 connecting auxiliary positioning bolt 6, the plane at the central axis place of two screws 22 and plane-parallel.Offering downwards two pin-and-holes for positive stop 7 connection from the upper surface of backboard 2, two pin-and-holes lay respectively at two ends before and after backboard 2.
The plate that main body is one piece of cuboid of lead-in wire locating piece 3, the front end face of base 1 and rear end face are fixed a lead-in wire locating piece 3 by fixing bolt 33 respectively.Two lead-in wire locating piece 3 structures are identical, are symmetrical arranged before and after base 1.Lead-in wire locating piece 3 and base about 1 to length identical, the left and right of lead-in wire locating piece 3 is to the left and right of the plane of symmetry and base 1 to the plane of symmetry at grade.Lead-in wire locating piece 3 is vertical with base 1, and the upper surface of lead-in wire locating piece 3 is beyond the upper surface of base 1.
Lead-in wire locating piece 3 is provided with wire jack 31 and watch window 32.Wire jack 31 is arranged downward vertically from the upper surface of lead-in wire locating piece 3.Wire jack 31 has 1,2 or 3, when wire jack 31 quantity is 1, this jack be arranged on lead-in wire locating piece 3 left and right to central authorities, the centrage of this jack be positioned at lead-in wire locating piece 3 left and right on the plane of symmetry.When wire jack 31 quantity is 2, two jacks lay respectively at the left and right of lead-in wire locating piece 3 to the left and right sides of the plane of symmetry, and are symmetrical arranged with it for the plane of symmetry to the both sides of the plane of symmetry in the left and right of lead-in wire locating piece 3.When wire jack 31 quantity is 3, middle jack be arranged on the left and right of lead-in wire locating piece 3 to central authorities, two jacks of both sides are symmetricly set on the both sides of central authorities' jack.The lead-in wire locating piece 3 of the present embodiment is provided with 3 jacks.
Watch window 32 is from the front end face of lead-in wire locating piece 3 rearwardly through lead-in wire locating piece 3, and watch window 32 is horizontally disposed cuboid through hole, and each wire jack 31 is vertical with watch window 32, and each wire jack 31 connects with watch window 32.Height h between upper surface and the lower surface of watch window 32 of lead-in wire locating piece 3 be weld after go between and expose the length of capacitor.After the lower end from up to down inserted from wire jack 31 lead-in wire to be welded during operation and go between props up the lower surface of watch window 32, then start welding operation.Whether the lower end that can observe lead-in wire at watch window 32 has propped up its lower surface.
Fuse locating rack 4 has two, and two fuse locating rack 4 structures are identical, and before and after base 1, lateral symmetry is arranged.It is internal that fuse locating rack 4 is positioned at two lead-in wire locating pieces 3.Fuse locating rack 4 is arranged on above base 1 by corresponding, to be located therein centre spring bolt 5, and fuse locating rack 4 can vertically move up and down relative to base 1.Before and after the locating surface 41 of fuse locating rack 4 to cross section be inverted isosceles trapezoid, the left and right of the locating surface 41 of fuse locating rack 4 to the left and right of the plane of symmetry and base 1 to the plane of symmetry, lead-in wire locating piece 3 left and right to the plane of symmetry at grade.
Auxiliary positioning bolt 6 has 2, it is arranged in the screw 22 of backboard 2, auxiliary positioning bolt 6 in screw 22 can left and right to movement, the extended screw in its right side 22 exposes from the right flank of backboard 2, auxiliary positioning bolt 6 moves left and right according to the size of capacitor body to be welded, it is ensured that the central axis of fuse to be welded lead-in wire locating piece 3 left and right on the plane of symmetry.
Positive stop 7 has two, is arranged on both sides before and after the upper end face of backboard 2.Positive stop 7 is rotatably connected on the upper end face of backboard 2 by rotational pin 71, and rotational pin 71 is arranged in the pin-and-hole above backboard.Positive stop 7 is cuboid plate, and the top of capacitor body to be welded contacts with the lower surface of positive stop 7.
When the lead-in wire welding tooling of the present invention uses, get out of the way by positive stop 7 forward side or to rear side rotation, the capacitor body of lead-in wire to be welded is placed on the locating surface 41 of fuse locating rack 4, before and after fuse, two ends are between the wire jack 31 of two lead-in wire locating pieces 3, and the metal spraying face of fuse is positioned at wire jack 31 edge.Regulation auxiliary positioning bolt 6, it is contacted with the outer peripheral face of fuse and props up so that the central axis of fuse go between locating piece 3 left and right on the plane of symmetry.Having positioned rear rotary spacing block 7 makes the top of circumferential lateral surface of fuse be resisted against the lower surface of positive stop 7, completes the fixing of fuse.
From up to down being inserted perpendicularly in wire jack 31 by lead-in wire to be welded, the lower end of lead-in wire props up the lower surface of watch window 32, then by the upper weld contacted with metal spraying face of lead-in wire on fuse metal spraying face, i.e. completes welding.
The length that after welding, each lead-in wire exposes fuse is h, and length is consistent.The length exposed that goes between after cased encapsulation is consistent.
When requiring that after welding, lead-in wire protruded length changes, change the lead-in wire locating piece 3 of different h value.
When about fuse when size changes, regulation auxiliary positioning bolt 6 with ensure fuse central axis lead-in wire locating piece 3 left and right on the plane of symmetry.Thus the frock of the present invention is not limited by fuse size, adapt to the lead-in wire weld task of different model fuse.
