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 meets eccentric requirement.Described device is by T-shaped screw rod, base plate to be fixed on the workbench of lathe.
Eccentric adjustable mechanism principle of the present invention: install bevel gear two another end mill of axle T-shaped chute, 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 by connecting rod, to regulate the eccentric distance of it and axle, the other end of connecting rod is arranged on fixed support, thereby utilize eccentric rotary, connecting rod drives casing to do the reciprocating motion of straight line, drive like this pipe joint not only to rotate but also do straight reciprocating motion, the relative pipe joint of cutter has just formed the cutting of saddle type curve.If Fig. 4 is theoretical intersection and the actual intersection comparison that utilizes this principle to form, can find out the feasibility of this eccentric center principle.
The course of work of the present invention is: first this device is lifted on the workbench of corresponding vertical milling, with T-shaped screw rod, this device base plate is pressed on workbench again, repacking is put with milling machine table clamping firm, guarantee that the center of main shaft is parallel with machine-tool platform traverse feed direction.The screw rod of eccentric adjustment governor motion, makes the high low head value of eccentricity value and saddle-shape pipe joint identical.Corresponding milling machine cutterhead clamping, on machine tool chief axis, is adjusted to the angle required with pipe joint groove.Pipe joint is placed on scroll chuck and is clamped, start the upper motor of this device and board main shaft, platen is done course feed motion can process the saddle nozzle pipe joint that meets 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, having realized cutter rotates, workpiece rotates and makes regular linear reciprocating motion, and platen drives fixture to do to enter normally tool backlash movement, can process the pipe joint with saddle nozzle.Serviceability of the present invention is stable, and applied widely, efficiency is high, simple and compact for structure, easy to operate, and the saddle-shape pipe joint groove surface accuracy, the roughness that process are high.The present invention has following features:
1, solved and can not process the problem of saddle nozzle on milling machine.
2, surperficial crudy and the production efficiency thereof of saddle nozzle have been improved.
3, this saddle-shape milling fixture can be processed caliber≤Φ 300, the pipe joint below wall thickness≤30 (can meet factory's required product requirement).
