Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
See Fig. 1 and Fig. 2, upper as can be seen from figure, fixture unit head of the present invention, comprises mount pad 1, is provided with rectangular enclosure on mount pad 1 surface, and in cavity, two ends are symmetrically installed with rotating shift fork 3 respectively by declutch shift shaft 2.In the middle part of cavity floor, be provided with center hole, be provided with the shift fork guiding plug 4 that can slide up and down in center hole, shift fork guiding plug 4 upper end is arranged in cavity, and shift fork guiding plug 4 is in the active shift fork slot 5 being circumferentially provided with ring-type of cavity segment.Be provided with actuating unit in mount pad 1 bottom surface, actuating unit and the shift fork plug 4 that leads is connected and centrally moves up or down in hole with the shift fork plug 4 that leads.One of them shifting block of two shift forks inserts in active shift fork slot, and another shifting block of two shift forks performs member acts as the driving head performing component separately to drive.
Particularly, another shifting block of two shift forks 3 is driven by slide block 6 and performs component 8 action, chute is provided with on the surface at mount pad 1, trough width is greater than cavity width, slide block 6 is located in chute and also can be horizontally slipped along chute, slide block 6 bottom surface is respectively equipped with passive shift fork jack 7, and another shifting block of shift fork 3 inserts in passive shift fork jack 7, and described execution component 8 is removably mounted on slide block 6.Described execution component 8 is for by the chuck of Workpiece clamping or claw, and two chucks or claw are oppositely arranged.
During work, actuating unit shift fork guiding plug 4 centrally moves down in hole, moving down of shift fork guiding plug 4 drives shift fork 3 to center rotating, because shift fork 3 is connected with slide block 6 passing hole, so slide block 6 under the transmission of shift fork 3 along chute slide in opposition, be arranged on slide block 6 owing to performing component 8, therefore perform component 8 also relative motion symmetrically, thus workpiece is synchronously clamped.If the complete needs of work pieces process unclamp exit, now actuating unit shift fork guiding is filled in centrally hole and to be moved up certain distance, and course of action with clamping on the contrary.
