The specific embodiment
Fig. 1 is the structural representation of a kind of fire hydrant valve rod of the utility model automatic clamping mechanism; Comprise workbench 1, workbench 1 is provided with main spindle box 2, main shaft free to rotate 3 is installed on main spindle box 2, in main shaft 3, be provided with the through hole that can pass through for valve rod, one end of main shaft 3 is provided with clamping body, and main shaft 3 is provided with the movable disk 7 that can be free to slide, also comprise drive rod 8, drive rod 8 near middles and workbench 1 are hinged by column, and drive rod 8 one end are provided with the chuck 9 suitable with movable disk 7, and movable disk 7 is connected by thrust bearing with chuck 9; Main shaft 3 is provided with the position-limit mechanism for restraint dish 7 positions;
Fig. 2 is the structural representation of guiding mechanism, on workbench 1, be also provided with guiding mechanism, guiding mechanism comprises transmission case 10, be installed in rotation on the rotating disk 11 on transmission case 10 and drive the driving mechanism of rotating disk 11, rotating disk 11 peripheries are provided with along rotating disk 11 periphery coilings, from extending to the guiding projection 12 near rotating disk 11 other end positions near rotating disk 11 positions, one end, as shown in Figure 4, the other end of drive rod 8 is provided with the guide rod suitable with guiding projection 12.Guiding projection 12 has two, occupies respectively half cycle space of chuck 9 peripheries, and the feeding frequency of the rotational frequency of rotating disk 11 and feed mechanism is 1:2.
Fig. 3 is the structural representation of position-limit mechanism, position-limit mechanism comprises that mounting disc 5 and the near middle of taking over a business 4, being sleeved on main shaft 3 that are fixedly mounted on main shaft 3 are hinged on the claw 6 in mounting disc 5, taking over a business 4 both ends of the surface is inclined-plane, claw 6 one end with take over a business 4 suitable, the other end and movable disk 7 are suitable, and the suitable end face of movable disk 7 and claw 6 is cambered surface.Claw 6 has four, in mounting disc 5, is circumferentially uniformly distributed.
The course of work is: feed mechanism completes feeding, rotating disk 11 rotates, and by guiding projection 12, drives drive rod 8 to rotate, and the chuck 9 of drive rod 8 ends drives movable disk 7 phase left movements, movable disk 7 one end are cambered surface, cambered surface drives claw 6 to clamp 4 inclined-plane, thereby clamping takes over a business 4, and rotating disk 11 is rotated further, apply a power left to main shaft 3, thereby pull main shaft 3 to left movement, the clamping body of main shaft 3 right-hand members is drawn into main spindle box 2, thereby clamping body shrinks clamping workpiece.When rotating disk 11 is rotated further, guide rod is from the end slippage of guiding projection 12, and drive rod 8 returns, clamp and remove, and feed mechanism starts feeding.
Adopt after such structure, by cam mechanism, realize the Automatic-clamping of clamp mechanism or unclamp, and synchronous with the feeding operation in system, changed the defect that need to manually complete with front clamp operation, save manpower, improved working (machining) efficiency, realized the automation of processing.
