The problem of long-axle workpieces difficult processing, and the workpiece quality processed is good, precision is high.
Technical scheme：A kind of boring head, including boring head body, facing head, tool rest, broach shell and cutter head, the boring head
Body is the hollow circular cylinder with stepped hole, and one end of boring head body is provided with the square thread being connected with boring bar, and the other end is provided with
Baffle plate, baffle plate are fixed by the first soket head cap screw, and the baffle plate allows the through hole that cutter head passes through, the boring head provided with one
The cylindrical of body is provided with keyway, and the wood key for being easy to stablize boring head body is provided with keyway.The facing head is by facing head and sky
Central spindle tube integrated connection forms, and its longitudinal section shape is " T " font, and facing head is plugged in the stepped hole of boring head body, puts down
The other end of capstan is provided with steel pipe indexing joint, and the tool rest is arranged on the facing head in boring head body, and knife is provided with tool rest
Set, the cutter head are arranged on broach shell by the second soket head cap screw, facing head forward or reverse under machine driving, band moving knife
Seat makees the leftward or rightward linear motion of radial direction along boring head intracoelomic cavity, and then promotes cutter head to stretch out or retract and be arranged on boring head body
The through hole of one end-stopping plate.
When facing head rotates forward, the radial alignment for promoting inner chamber of the tool rest along boring head body to make to the left is moved, and cutter head is stretched out and pacified
Mounted in the through hole of boring head body left end baffle plate, boring processing is carried out to workpiece.When facing head inverts, pulling tool rest is along boring head body
Chamber makees radial alignment motion to the right, by cutter head retraction boring head body, completes the processing of workpiece.
The present invention has the advantages that compared with prior art：The present invention is simple in construction, ingenious in design reasonable in design,
Solve the problems, such as that traditional boring head can not process stepped hole thin and long shafts work pieces process difficulty broad in the middle small in ends, the boring head
Cutter head can stretch out or retract with axis of the facing head of rotation along boring head, can process the endoporus of different-diameter, especially for
Thin and long shafts workpiece broad in the middle small in ends, the gang tool can easily be processed to it, can be right on engine lathe
It is accurately controlled, and greatly increases production efficiency, and the part quality processed is good, and precision is high.
