Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the scheme of installation of locating ring and dog screw in Fig. 1;
Wherein: 10, axle core; 11, through hole; 12, step surface; 13, screwed hole; 20, pull bar; 21, locking nut; 22, locating ring; 221, recess; 23, flange; 30, pulling claw; 40, disk spring; 41, gland; 50, dog screw.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As shown in Figure 1, 2, for a kind of electric main spindle broach of the present utility model mechanism, it comprises axle core 10, pull bar 20, pulling claw 30, disk spring 40 and cylinder (not shown), cylinder is arranged on the top ends of axle core 10, the expansion link of this cylinder is connected with the top of pull bar 20, cylinder moves downward with respect to axle core 10 for pushing drawing rod 20, completes and unloads cutter action.The inside of axle core 10 be provided with one from it end face extend to the through hole 11 of its lower surface, this through hole 11 extending axially along axle core 10, and through hole 11 is provided with a step surface 12 near the part of axle core 10 upper surfaces, pull bar 20 cross-under are in the inside of through hole 11 and can axially sliding with respect to axle core 10 along axle core 10, on pull bar 20, be bolted with a locking nut 21, this locking nut 21 is resisted against the below of step surface 12, when pull bar 20 moves upward to the position that locking nut 21 coordinates with step surface 12, pull bar 20 is stoped by step surface 12, can not continue to move upward with respect to axle core 10.
Part near its lower surface on the sidewall of axle core 10 is provided with a screwed hole 13, this screwed hole 13 extends to the inwall of through hole 11 along the radially ecto-entad of axle core 10, on pull bar 20, be socketed with a locating ring 22 that is positioned at locking nut 21 belows, the side of locating ring 22 is provided with a recess 221, this recess 221 and screwed hole 13 aliging radially, screwed hole 13 inside are bolted with a dog screw 50, after screwing dog screw 50, the medial end of dog screw 50 is plugged in recess 221, prevents locating ring 22 axially sliding with respect to axle core 10 along axle core 10.
Disk spring 40 is arranged between locking nut 21 and locating ring 22, this butterfly spring is for upwards pressing at top locking nut 21, when cylinder pushing drawing rod 20 moves downward, 21 of locking nuts push up the upper end of pressing disk spring 40 downwards, because locating ring 22 and the axial location of axle core 10 keep fixing, thereby, disk spring 40 can be compressed, pulling claw 30 is along with pull bar 20 moves downward to the tapered hole of axle core 10 bottoms, and pulling claw 30 automatically springs open, and completes the cutter process of unloading.During upper slitter, cylinder shrinks, and disk spring 40 is upwards pressed at top locking nut 21, makes locking nut 21 move to the position coordinating with step surface 12, and now, cutter is installed in place, and completes upper slitter process.Above-mentioned disk spring 40 of the present utility model can also be to adopt other elasticity original paper to substitute, as long as can provide locking nut 21 elastic stress that upwards press on top.
The utility model is when dismounting, only dog screw 50 need to be screwed out from screwed hole 13, the medial extremity of dog screw 50 is departed from from recess 221, pull bar 20, pulling claw 30 can be split out from the lower ending opening of through hole 11, without dismounting cylinder, simplify unloading process, be convenient to the replacing of maintenance and parts.During installation, pull bar 20 penetrating in through hole 11 from the bottom to top after recess 221 and screwed hole 13 radially aligneds, screws in dog screw 50 in screwed hole 13.
Between the top ends of disk spring 40 and locking nut 21, be also provided with a gland 41 being enclosed within on pull bar 20.
On pull bar 20, be provided with one and prevent the flange 23 that locating ring 22 drops downwards, when mounted, pushing tow pull bar 20 makes progress, make flange 23 upwards press locating ring 22 in top, the recess 221 on locating ring 22 overcomes the elastic stress of 40 pairs of locating rings 22 of disk spring, so that can align with screwed hole 13 fast.
To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
