PURPOSE:To improve the efficiency of welding operation for production of diversified kinds in a small quantity by forming a jig table for clamping work in such a way that the table can be attached and detached to and from a slide plate for conveying work moving back and forth on an installing bed and that the table can be surely locked with high centering accuracy after setting. CONSTITUTION:A pawl plate 21 fixed to the bottom surface of a jig table 15 for clamping a work and a pawl plate 27 fixed atop a slide plate 11 moving back and forth on an installing leg bed for carrying said work into and from an automatic welding machine are detained and fixed freely engageably and disengageably by means of a hook segment 40 which is fitted onto the outside circumferential surfaces of both plates and can be operated to turn. A guide post 34 for centering which is erected and united at and to the center of the pawl plate 27 of the plate 11 and the pawl plate 21 of the table 15 are fitted to each other freely insertably and removably by means of the point contact between a pole retainer 35 fitted onto the former and a guide bushing 26 for centering fitted into the latter. The table 15 is therefore made attachable and detachable to and from the slide plate 11 for conveying the work and is made exchangeable. |
