The technical scheme of the frock of the inclined hole on processing sleeve workpiece sidewall of the present utility model, the cone match of outer cone mandrel and inner cone ringfeder is adopted to carry out clamping workpiece, namely the conical surface of outer cone mandrel and inner cone ringfeder will select just right cone angle, this cone angle requires it is can not self-locking under outer cone mandrel and inner cone ringfeder unclamp free state, but under tension, there is the fastening force being enough to fixation workpiece, so just can make work-handling convenient.Tool locating speed of the present utility model is fast, and ensure the accuracy of inclined hole processing, work efficiency significantly improves.
Accompanying drawing explanation
Fig. 1 is the structural representation of the frock of inclined hole on processing sleeve workpiece outer surface of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, sleeve workpiece 4 comprises benchmark endoporus 40 and is positioned at the locating hole 41 on outer surface.
The frock of a kind of inclined hole processed on sleeve workpiece outer surface of the present utility model, comprise frame 1, bushing plate 7, drill bushing 8, cover for seat 9, cylinder 10, outer cone mandrel 6, inner cone ringfeder 5, position degree positioning seat 2 and position degree spacer pin 3, wherein:
Frame 1 comprises base plate 11 and to be arranged on base plate 11 and to have the tilt prop 12 of a perforation;
Bushing plate 7 is horizontally fixed on the upper end of tilt prop 12, this bushing plate be provided with one with the through hole of horizontal plane;
In the through hole of drill bushing 8 installing drill template 7, this drill bushing 8 be provided with one with the drill bit bore of horizontal plane;
On the front end face that cover for seat 9 is fixed on the tilt prop 12 of frame 1 and rear portion is plugged in the perforation of tilt prop 12;
On the rear end face that cylinder 10 is arranged on the tilt prop 12 of frame 1 and its piston rod interts in the endoporus of cover for seat 9;
Outer cone mandrel 6 is connected to the front end of the piston rod of cylinder 10 and is positioned at the front of the front end face of cover for seat 9;
The front end face that inner cone ringfeder 5 is placed in cover for seat 9 is set in the periphery of outer cone mandrel 6, and the tapering of the tapering of the inner hole surface of this inner cone ringfeder 5 and the outer surface of outer cone mandrel 6 is adaptive;
The side being placed in described cover for seat of workpiece 4 is set in the periphery of described inner cone ringfeder;
The front end face that position degree positioning seat 2 is fixed on the tilt prop 12 of frame 1 is positioned at below cover for seat 9;
One of position degree spacer pin 3 is flat, and other end is cylinder, and one of the flat of position degree spacer pin 3 is plugged on position degree positioning seat 2, and cylindrical one is plugged in the locating hole 41 of workpiece 4;
The frock of a kind of inclined hole processed on sleeve workpiece outer surface of the present utility model in use, first can adjust the angle between tilt prop 12 and base plate 11, with inclined hole angle on the outer surface meeting workpiece 4.When the piston rod of cylinder is in elongation state, the outer surface of outer cone mandrel 6 and the inner hole surface of inner cone ringfeder 5 are in non-mated condition, the external diameter of inner cone ringfeder 5 is less than the diameter of the benchmark endoporus of workpiece 4, workpiece 4 is very easy to installation and has just put in place, cylindrical one of position degree spacer pin 3 is inserted in the locating hole 41 of workpiece 4 simultaneously, then pneumatic element hand-operated valve is started, the piston rod retraction of control cylinder 10, the outer surface of outer cone mandrel 6 and the inner hole surface of inner cone ringfeder 5 are fitted tensioner, thus fitted tensioner in the surface of the outer surface of inner cone ringfeder 5 and the benchmark endoporus 40 of workpiece 4, with the inclined hole 42 making the drill bit bore on drill bushing 8 aim at the outer surface of workpiece 4 to be processed, make the inclined hole 42 on workpiece 4 to be processed coaxial with drill bit bore, namely the inclined hole 42 on workpiece 4 and horizontal plane, starting drilling machine makes the drill bit on drilling machine through the outer surface of the drill bit bore drill workpiece 4 of drill bushing 8, get final product the inclined hole 42 on processing work 4.After machining, operation pneumatic element hand-operated valve, the piston rod of control cylinder 10 stretches out, make the outer surface of outer cone mandrel 6 that the inner hole surface of inner cone ringfeder 5 is separated, the rebounding of outer surface of inner cone ringfeder 5 is reduced, with the generation gap, surface of the benchmark endoporus 40 of workpiece 4 simultaneously, discharge location degree spacer pin 3 again, workpiece 4 can conveniently unload, and just complete one manufacturing procedure, work efficiency significantly improves.
