Summary of the invention
The object of the present invention is to provide a kind of device can processing saddle-shape pipe joint groove on milling machine.
The object of the present invention is achieved like this: it comprises base plate, casing, worm gear, pressing plate, motor, eccentric adjustable mechanism, fixed support, bevel gear one and bevel gear two, described casing is contained on base plate by pressing plate, mounted motor on casing left plate, described main shaft is supported by the lateral shaft bearing assembly of casing, main shaft is provided with worm gear, described motor is provided with motor pulley, motor pulley is connected with the belt pulley on worm screw by belt, worm screw is meshed with the worm gear be contained on main shaft, main shaft right-hand member has installed scroll chuck, main shaft left end has installed bevel gear one, eccentric adjustable mechanism is arranged on casing, bevel gear one is meshed with the bevel gear two on the minor axis being contained in eccentric adjustable mechanism, connecting rod one end is contained on eccentric adjustable mechanism, the other end is contained in support bracket fastened axle, fixed support is arranged on base plate.
Described casing can be free to slide and do regular linear reciprocating motion on base plate.
Described main shaft is supported by casing lateral shaft bearing assembly, and the worm screw that the worm gear above it is supported by casing longitudinal axis bearing assembly drives.Described eccentric adjustable mechanism is that adjusting screw carrys out satisfied eccentric requirement.Described device is fixed on the workbench of lathe by base plate by T-shaped screw rod.
Eccentric adjustable mechanism principle of the present invention: installing the T-shaped chute of another end mill of axle of bevel gear two, T-shaped slide block is contained in T-shaped chute, T-shaped slide block is connected with connecting rod again simultaneously, T-shaped slide block is the eccentric distance being regulated it and axle by connecting rod, the other end of connecting rod is arranged on fixed support, thus utilize eccentric rotary, connecting rod drives casing to do the reciprocating motion of straight line, such drive pipe joint not only rotates but also do straight reciprocating motion, and the relative pipe joint of cutter just defines the cutting of saddle type curve.If Fig. 4 is that theoretical intersection compares with the actual intersection utilizing this principle to be formed, can find out, the feasibility of this eccentric center principle.
The course of work of the present invention is: be first lifted on by this device on the workbench of corresponding vertical milling, with T-shaped screw rod, this device base plate is compressed on the table again, repacking is put with milling machine table clamping firm, ensure that the center of main shaft is parallel with machine-tool platform traverse feed direction.The screw rod of eccentric adjustment governor motion, makes eccentricity value identical with saddle-shape pipe joint height low head value.By corresponding milling machine cutterhead clamping on machine tool chief axis, adjust and the angle needed for pipe joint groove.Be placed in by pipe joint on scroll chuck and clamp, start motor and board main shaft on this device, course feed motion done by platen can process the saddle nozzle pipe joint meeting drawing requirement.
The present invention be directed to the grip device of the saddle-shape the processed pipe joint groove of vertical knee-type milling machine design, achieve cutter to rotate, not only workpiece rotates but also make regular linear reciprocating motion, and platen drives fixture to do and enter tool backlash movement normally, the pipe joint of band saddle nozzle can be processed.Serviceability of the present invention is stablized, and applied widely, efficiency is high, simple and compact for structure, easy to operate, and the saddle-shape pipe joint groove surface accuracy processed, roughness are high.The present invention has following features:
1, problem milling machine can not being processed saddle nozzle is solved.
2, improve crudy and the production efficiency thereof on the surface of saddle nozzle.
3, this saddle-shape milling fixture can process the pipe joint (can meet factory's required product requirement) of below caliber≤Φ 300, wall thickness≤30.
