Abstract

The utility model relates to an inner and outer thread machining whirl-wind milling machine, which comprises a main motor, a whirl-wind mill head frame and a supporting seat. The whirl-wind mill head frame is fixed at one side of the supporting seat through a centre shaft bolt and a connecting bolt, the main motor is arranged on the whirl-wind mill head frame in which an outer rotary head or an inner rotary cutter holder is arranged. A helix angle stretching screw is arranged on the supporting seat. The side of the joint of the whirl-wind mill head frame and the supporting seat is provided a helix angle scale. The inner and outer thread machining whirl-wind milling machine has the advantages that: the surface smooth finish and the precision of processed worm screw mandrels and nuts are greatly improved through the improvement of the earthquake resistance and the contact strength of connecting with a lathe; available adjustment of a helix angle causes a left and a right pressure angles of a processed thread to be consistent and symmetrical strictly; the pitch diameter of the thread can be effectively controlled, and the shortcoming that the traditional whirl-wind milling machine only performs the rough machining but can not perform the finish machining is changed thoroughly.

Description

A kind of internal and external threads processing whirlwind mills
Technical field
The utility model relates to a kind of finish turning screw device, relates in particular to a kind of internal and external threads processing whirlwind and mills.
Background technology
Whirlwind mills and is mounted on the lathe and the supporting high-speed milling screw device of lathe, whirlwind is milled on the T type circular groove that is installed on the lathe middle carriage (not changing the lathe structure convenient disassembly), the lathe holding workpiece is finished the low speed feed motion, whirlwind mills main motor and rotates at a high speed by the hard alloy cutter that motor pulley, spindle pulley drive on outward turning cutterhead or the inward turning knife bar, finish cutting movement, mill out screw thread from workpiece, its milling speed height (speed reaches 400m/min), working (machining) efficiency is fast, and adopts compressed air to carry out the chip removal cooling.It is that shock resistance that is connected with lathe and contact strength that whirlwind mills are not high by the steel plate welding that traditional whirlwind mills; To mill lead angle be to be finished by backing plate to the tradition whirlwind, and it is two machines that whirlwind mills the processing internal and external screw thread, has increased cost, and traditional whirlwind mills and can only carry out roughing, cannot carry out fine finishining, improves 10---30 doubly than traditional processing mode.
The utility model content
The purpose of this utility model provides a kind of internal and external threads processing whirlwind and mills, and to mill processing cost bigger to overcome traditional whirlwind, can only carry out roughing, cannot carry out accurately machined deficiency.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of internal and external threads processing whirlwind mills, comprise main motor, cyclone milling head frame, bearing, outward turning cutterhead or inward turning knife bar, lead angle adjustment screw rod, the cyclone milling head frame is fixed on bearing one side by middle axle bolt, connecting bolt, main motor is arranged on the cyclone milling head frame, and outward turning cutterhead or inward turning knife bar are arranged in the cyclone milling head frame; Main motor connects outward turning cutterhead or inward turning knife bar by spindle pulley, motor pulley, and lead angle is adjusted screw rod and is arranged on the bearing; The side of cyclone milling head frame and bearing junction is provided with the lead angle scale.During threading the outward turning cutterhead is loaded onto, during machining internal thread the inward turning knife bar is loaded onto, mill at a whirlwind and just can finish internal and external threads processing, the lathe holding workpiece is finished the low speed feed motion, main motor rotates at a high speed by the hard alloy cutter that motor pulley, spindle pulley drive on outward turning cutterhead or the inward turning knife bar, finishes cutting movement; With middle axle bolt is the center of circle, and connecting bolt is a radius, and the lifting of adjusting screw rod by lead angle reaches the rotation of cyclone milling head frame, finishes the accurate adjustment of lead angle scale.
The beneficial effect that internal and external threads described in the utility model processing whirlwind mills is: by the shock resistance that is connected with lathe and the raising of contact strength, the Worm and screw of processing, nut surface smoothness, precision increase substantially; Effective adjustment of lead angle makes pressure angle strict symmetry in the processing rear thread left and right sides consistent; The pitch diameter of thread can effectively be controlled, and has thoroughly changed traditional whirlwind and has milled and can only carry out roughing, cannot carry out accurately machined deficiency, range of work external screw thread 6mm-120mm, 7 grades of internal thread 26mm-400mm machining accuracies.

Among the figure:
1, main motor; 2, cyclone milling head frame; 3, bearing; 4, outward turning cutterhead; 5, lead angle is adjusted screw rod; 6, spindle pulley; 7, motor pulley; 8, inward turning knife bar; 9, middle axle bolt; 10, connecting bolt; 11, lead angle scale.
The specific embodiment
Shown in Fig. 1-4, the described internal and external threads processing of the utility model embodiment whirlwind mills, comprise main motor 1, cyclone milling head frame 2, bearing 3, cyclone milling head frame 2 is fixed on bearing 3 one sides by middle axle bolt 9, connecting bolt 10, main motor 1 is arranged on the cyclone milling head frame 2, is provided with outward turning cutterhead 4 in the cyclone milling head frame 2; Bearing 3 is provided with lead angle and adjusts screw rod 5, is provided with lead angle scale 11 in the side of cyclone milling head frame 2 and bearing 3 junctions.
As shown in Figure 5, the outward turning cutterhead 4 on the cyclone milling head frame 2 can replace with inward turning knife bar 8.During threading outward turning cutterhead 4 is loaded onto, during machining internal thread inward turning knife bar 8 is loaded onto, mill at a whirlwind and just can finish internal and external threads processing, time and cost have been saved, the lathe holding workpiece is finished the low speed feed motion, main motor 1 rotates at a high speed by the hard alloy cutter that motor pulley 7, spindle pulley 6 drive on outward turning cutterhead 4 or the inward turning knife bar 8, finishes cutting movement; With middle axle bolt 9 is the center of circle, and connecting bolt 10 is a radius, and the lifting of adjusting screw rod 5 by lead angle reaches the rotation of cyclone milling head frame 2, finishes the accurate adjustment of lead angle scale 11.
