Abstract
Abstract An apparatus comprising a jig on which are placed, through the agency of guide pins, a member for caulking made of a thermoplastic resinous material and formed therein with bores and a member to be caulked also made of a thermoplastic resinous material and formed thereon with projections for caulking, the first-mentioned member being superposed on the last-mentioned member with the projections for caulking each being received in one of the bores. The apparatus also comprises a vertically movable pressure receiving plate adapted to be moved downwardly toward the member for caulking, and a plurality of pressers adapted to move upwardly the member to be caulked. The downwardly moving pressure receiving plate moves the guide pins downwardly to release them from engagement with the member to be caulked, while the member to be caulked moved upwardly by the plurality of pressers is moved away from the upper surface of the jig and pressure is applied by the pressers to the associated projections for caulking. Then pressure waves of ultrasonic frequency are transmitted through a caulking tool to the upper end of each projection for caulking so as to ultrasonically treat the projections for caulking to thereby caulk the edges of the projections for caulking and the member for caulking.

A CAULKING APPARATUS COMPRISING: A. A JIG INCLUDING A SUPPORTING SURFACE AND FORMED WITH A CUTOUT, SAID JIG BEING PROVIDED WITH A PLURALITY OF GUIDE PINS MOUNTED IN HOLES FORMED IN THE JIG AND EACH BEING URGED BY A RESILIENT MEMBER TO EXTEND UPWARDLY FROM SAID SUPPORTING SURFACE, SAID SUPPORTING SURFACE BEING ADAPTED TO RECEIVE THEREON A MEMBER TO BE CAULKED AND A MEMBER FOR CAULKING, SAID MEMBER TO BE CAULKED HAVING A PLURALITY OF PROJECTIONS FOR CAULKING AND SAID MEMBER FOR CAULKING BEING FORMED WITH A PLURALITY OF OPENINGS, SAID TWO MEBERS BEING ARRANGED RELATIVE TO EACH OTHER SUCH THAT THE MEMBER FOR CAULKING IS SUPERPOSED ON THE MEMBER TO BE CAULKED WITH THE PROJECTIONS FOR CAULKING BEING RECEIVED IN THE RESPECTIVE OPENINGS, SAID PROJECTIONS FOR CAULKING BEING DISPOSED ABOVE SAID CUTOUT, B. A PRESSURE RECEIVING PLUTE ARRANGED IN JUXTAPOSED RELATION WITH SAID SUPPORTING SURFACE OF SAID JIG PROVIDED WITH THE GUIDE PINS AND SPACED THEREFROM A PREDETERMINED DISTANCE, SAID PRESSURE RECEIVING PLATE BEING FORMED WITH A PLURALITY OAPERTURES EACH IDSPOSED IN A POSITION CORRESPONDING TO A POSITION IN WHICH ONE OF SAIDPROJECTIONS FOR CAULKING IS DISPOSED, C. MEANS FOR MOVING SAID PRESSURE RECEIVING PLATE IN SLIDING MOTION TOWARD SAID SUPPORTING SURFACE OF SAID JIG, D. A PLURALITY OF PRESSERS EACH DISPOSED IN A POSITION CORRESPONDING TO A POSITION IN WHICH ONE OF SAID APROJECTIONS FOR CAULKING OF SAID MEMBER TO BE CAULKED IS DISPOSED, SAID MEMBER TO BE CAULKED BEING POSITIONED IN FACE-TO-FACE RELATION WITH SAID PRESSURE RECEIVING PLATE AND DISPOSED ABOVE SAID CUTOUT FORMED IN SAID JIG, E. MEANS FOR APPLYING PRESSURE TO CAUSE ALL THE PRESSERS TO MOVE IN THE DIRECTION OF SAID PRESSURE RECEIVING PLATE AUNTIL THE PRESSERS EACH REACH A POSITION IN WHICH IT IS DISPOSED ABOVE SAID SUPPORTING SURFACE OF SAID JIG, F. A PLURALITY OF RESILIENT MEMBERS EACH ASSOCIATED WITH ONE OF SAID PLURALITY OF PRESSERS AND INTERPOSED BETWEEN EACH OF SAID PRESSERS AND SAID PRESSURE APPLYING MEANS, AND G. A ULTRASONIC GENERATOR MECHANISM ADAPTED TO BE BROUGHT INTO ENGAGEMENT WITH EACH OF SAID PROJECTIONS FOR CAULKING OF SAID MEMBER TO BE CAULKED EXTENDING THROUGH ONNE OF SAID PLURALITY OF APERTURES FORMED IN SAID PRESSURE RECEIVING PLATE SO AS TO TRANSMIT PRESSURE WAVES OF ULTRASONIC FREQUENCY TO EACH SAID POJECTION WHEREBY SAID PROJECTIONS FOR CAULKING CAN BETREATED ULTRASONICALLY TO CAULK THE EDGES OF THE MEMBER FOR CAULKING AND THE PROJECTIONS FOR CAULKING.
