The technical solution of the utility model is this a kind of weld jig, described weld jig comprises plinth, be positioned on the relative both ends of the surface of base, one end is equipped with the fixed support perpendicular to base plane, the other end is equipped with turnover panel, limiting bracket perpendicular to base plane is installed on the end face adjacent with turnover panel with fixed support on the base, compress positioning beam on being parallel to each other, the two ends of preceding compression beam are connected with turnover panel with fixed support respectively, fixed support, compress the last fixture of positioning beam on the top of turnover panel is respectively equipped with and fixes, the upper surface of base is provided with at least one alignment pin.
At least one side fixture is installed on the described turnover panel, at least one preceding fixture is installed on the preceding compression beam.
Described going up between fixture and fixed support, the turnover panel all is connected by bearing pin, and last fixed support can rotate on fixed support and turnover panel along the axis of bearing pin.
Be connected by bearing pin between described turnover panel and the base, turnover panel can be done 90 °～360 ° along the axis of bearing pin and rotatablely move.
Be provided with locating piece between described alignment pin and the base, locating piece has one at least, and an alignment pin is installed on each locating piece at least.
Described limiting bracket is faced the B face of base and the upper surface C face of base in the face of A face, the fixed support of base, and A face, B face and C face are three orthogonal basal planes.
A kind of weld jig with above-mentioned special construction has the following advantages:
1, by successively each parts of circuit breaker cart frame being assemblied in the weld jig of this kind special construction from left plate, in the dimensional accuracy that has guaranteed the cart frame welding, improved the efficient of cart frame welding, circuit breaker cart frame has good interchangeability during batch making, has improved the circuit breaker cart security of products.
2, the weld jig structure fabrication is with low cost, and effect is fairly obvious, has saved the production cost of circuit breaker cart frame to a great extent.
