Example (b):
referring to fig. 1 to 3, the multi-station pressing device in the preferred embodiment of the present invention includes a tooling table 1, wherein the tooling table 1 is used for placing a workpiece 13; the first transmission rod 2 is arranged on one side, away from the workpiece 13, of the tool table 1; the pressing pieces are arranged in pairs and are respectively arranged at two ends of the first transmission rod 2, one end of each pressing piece is connected with the first transmission rod 2, and the other end of each pressing piece penetrates through the tool table 1 and presses the workpiece 13 along the axial direction of the tool table; the tool table 1 is connected to the butt- joint rod 3, 3 one end of butt-joint rod, and 2 axial centers of the first transmission rod of its other end vertical butt are located, and this butt-joint rod 3 can follow its axial motion in order to change the butt power of exerting to first transmission rod 2.
When utilizing frock platform 1 to compress tightly work piece 13 in pairs, butt pole 3 is through driving first transmission rod 2 in vertical and is moving for the piece that compresses tightly that links to each other with first transmission rod 2 corresponds and compresses tightly or loosen work piece 13. The lever structure that connects pole 3 and first transfer line 2 to form can carry out certain skew on the horizontal plane to the work piece 13 that possesses certain deviation, and then compresses tightly two work pieces 13 and fix on frock platform 1 to ensure the stability of work piece 13 processing.
The one end that frock platform 1 is connected to butt joint pole 3 in this application is fixed through hex screw, and the tip screw thread matching of hex screw and this butt pole 3 when the high butt force to first transfer line 2 of changing of vertical regulation butt joint pole 3 of needs, twists through spanner etc. and moves hex screw and drive 3 vertical lifts of butt joint pole.
Further, as a preferred embodiment of the present invention, a spherical recess 4 is provided at the axial center of the first transmission rod 2, and a spherical protrusion 5 is correspondingly provided at one end of the abutting rod 3 abutting against the first transmission rod 2, and the spherical protrusion 5 is correspondingly accommodated in the spherical recess 4. When utilizing 2 axial direction centers of the first transfer line of 3 butts of butt pole, when butt pole 3 only simply supported and leans on 2 surfaces of first transfer line, when there is machining error in the work piece 13 of the 2 both ends crimping of first transfer line, cause the pressure imbalance of the 2 both ends butts of first transfer line easily, cause the butt pole 3 and 2 butt positions of first transfer line to take place the skew, and then lead to this multistation closing device can't compress tightly a plurality of stations. Therefore, the spherical groove 4 is formed in the axial center of the first transmission rod 2, the spherical protrusion 5 is correspondingly arranged on the abutting rod 3, the first transmission rod 2 and the abutting rod 3 form a stable lever structure through the form that the spherical protrusion 5 is matched with the spherical groove 4, when the workpieces 13 at the two ends have machining errors, the first transmission rod 2 can offset correspondingly in a small range, and the enough pressing force of the pressing pieces at the two ends of the first transmission rod 2 on the workpieces 13 is ensured.
