The inner hole key slot milling head
Technical field
The utility model relates to the machining equipment field, relates in particular to a kind of inner hole key slot milling head.
Background technology
In the conventional mechanical processing, inner hole key slot generally adopts slotting machine or planer processing, but when workpiece volume and weight are excessive, the workbench of existing slotting machine and planer can not this workpiece of clamping, cause inner hole key slot to process, therefore need a kind of machining equipment that is used for the large floor boring and milling machine to carry out Milling Process the small-sized inner hole key slot on the workpiece.
Summary of the invention
The purpose of this utility model provides a kind of inner hole key slot milling head, and the energy clamping by the directions X feeding of boring and milling machine, is processed the inner hole key slot of workpiece on the boring and milling machine anvil block on the ram of large floor boring and milling machine.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The inner hole key slot milling head, comprise belt pulley one, support and carriage arbor, the coaxial diminished shaft that is provided with on the belt pulley one, carriage arbor is connected with the boring and milling machine ram by support, described carriage arbor comprises belt pulley two, slide and axle, belt pulley two links to each other with axle, and slide links to each other by screw two with support, is provided with bearing between axle and the slide, described axle hollow, internal diameter and milling cutter shank diameter coupling, axle one side is provided with jackscrew, links to each other by V belt between belt pulley one and the belt pulley two.
Be provided with adjustment screw between described slide and the support.
Prior art is compared, and the beneficial effects of the utility model are: 1) this milling head is simple in structure, and is easy for installation, and manufacturing cost is lower.2) can be used with large-scale boring and milling machine, as the T6920 boring machine etc., this milling head is installed on the T6920 boring machine ram main shaft, by the directions X feeding of boring machine, by belt transmission, drives slotting cutter and finishes keyway processing, guarantees crudy and duration, saves production cost.3) straight shank end mill clamps with jackscrew, have simple in structure, characteristics such as clamping force is big.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, it is the utility model inner hole key slot milling head example structure schematic diagram, with the T6920 boring machine is example, comprise belt pulley 1, support 2 and carriage arbor 3, the coaxial diminished shaft 4 that is provided with on the belt pulley 1, diminished shaft 4 is consistent with boring spindle 5 taperings, guarantees the axiality of belt pulley 1 and boring spindle 5, and belt pulley 1 is connected by screw 1 with boring spindle 5; Carriage arbor 3 is connected with boring machine ram 6 by support 2, carriage arbor 3 comprises belt pulley 27, slide 8 and axle 9, belt pulley 27 links to each other with axle 9, slide 8 links to each other by screw 2 11 with support 2, be provided with bearing 12 between axle 9 and the slide 8, axle 9 is a hollow structure, internal diameter and milling cutter 13 shank diameters coupling, axle 9 one sides are provided with jackscrew 14, link to each other by V belt 15 between belt pulley 1 and the belt pulley 27.Be provided with adjustment screw 16 between slide 8 and the support 2.
When the utility model inner hole key slot milling head uses, need earlier diminished shaft 4 to be put into the taper hole of boring spindle 5, with screw 1 belt pulley 1 is installed on the boring spindle 5 again, then carriage arbor 3 is connected with support 2, again support 2 is installed on the boring machine ram 6, regulates along the Z direction, make belt pulley 1 and belt pulley 27 in same plane by boring spindle 5, V belt 15 can be installed, the tightness of V belt 15 be installed be regulated by adjustment screw 16.Milling cutter 13 is installed on carriage arbor 3 at last, and milling cutter 13 is the straight shank end mill of diameter 16, and the cutter mounting means adopts side-strengthened to clamp with jackscrew 14.
