The utility model content
In order to solve a sub-folder tool by the drilling operation of the bolt through-hole of simple and easy adjustment realization front hub or brake drum, the utility model proposes a kind of anchor clamps for brake drum or front hub boring.
The technical solution of the utility model is as follows:
A kind of anchor clamps for brake drum or front hub boring comprise the clamp body 1 of cylindrical tube shape, clamp body 1 crown center offers through hole, the bottom is the installing plate of rectangle, the clamp body 1 interior coaxial axle 12 that is provided with, the upper end of axle 12 extends outside the through hole of clamp body 1, and the upper end of axle 12 is the screw rod of Step Shaft shape, cooperate with screw rod and to be provided with locking nut 6, be arranged with pressing plate 5 on the screw rod, improvement is: described clamp body 1 end face is fixed with the location-plate of ring-type, and the end face of location-plate is locating surface 15, and the inner periphery place of location-plate is provided with the locating ring that raises up, the inner peripheral surface of locating ring is inner circle locating surface 13, and the outer circumference surface of locating ring is excircle orientation face 14; Radially uniform eight U-lags, the outward opening of described U-lag of offering of the excircle of location-plate; Be laid with the locating piece of four rectangles on the location-plate by soket head cap screw, wherein a locating piece is provided with the second spacer pin 8.
Described pressing plate 5 is the strip pressing plate, and the two ends of length direction are Y-shaped respectively, and the both sides of width are respectively equipped with handle 4.
Described pressing plate 5 is the pressing plate of circular open, namely directly upwards offers the groove that connects circumference in a side.
Described locating piece is box-shaped, and corresponding top, the left and right sides offers respectively inner groovy, and the bottom in the inner groovy of both sides offers respectively installing hole, cooperates in the installing hole to be provided with the soket head cap screw that is connected with location-plate.
Useful technique effect of the present utility model is: transfer processing to during front hub at lathe by used for processing brake drum, simultaneously pressing plate is replaced by open washer and namely can be used as boring grab into front hub as long as by soket head cap screw four locating pieces are installed on locating ring.And two kinds of parts switch and only need to switch procedure, and not needing to adjust machining coordinate is origin position, and the whole handoff procedure time was reduced to 5-10 minute by original 1-2 hour, can stablize the crudy that guarantees two products simultaneously.The utility model is a kind of anchor clamps for brake drum or front hub boring, becomes more simple, efficient when two kinds of product processing are switched.
