Description
Technical field
The utility model relates to a kind of numerically controlled lathe and uses milling head, relates in particular to a kind of outer milling head of angle adjustable.
Background technology
At present adopt in the whirlwind milled processing mode more during the small-sized extraordinary screw thread of work in-process, and the mode of milling can not be processed steep-lead thread in the whirlwind, and form processing is hilted broadsword processing, and blade is few, and production efficiency is lower.Some lathe from external import can overcome the shortcoming of milling in the whirlwind, but the import lathe costs an arm and a leg, and acquisition cost is high, can't popularize in field of machining.
Summary of the invention
To the problems referred to above, the utility model mills the mode machining screw outside proposing to utilize, and provides the angle adjustable that a kind of suitable steep-lead thread is processed and price is low, working (machining) efficiency is high outer milling head.
The technical scheme that the utility model adopts is following: the outer milling head of a kind of angle adjustable; Comprise base and gear-box; Gear-box and base flexibly connect; Be provided with the cutter spindle of front end tep reel milling cutter in the said gear-box; Gear-box outside and one be used to adjust gear-box angle of inclination and then adjustment disk milling cutter angle the angle adjustment worm-and-wheel gear be connected, said angle adjustment worm-and-wheel gear comprises the angle direction board of an angle adjustment worm screw, an angle adjustment worm gear and angle adjustment worm screw one end, said angle adjustment worm gear and gear-box are affixed.
Gear-box and cutter spindle axial restraint, rotational angle adjustment worm screw drives the angle adjustment worm gear and rotates; Thereby the driven gear case rotates along the worm gear axis direction; Gear-box leans forward or the hypsokinesis certain angle, tilts with same angle and same direction through cutter spindle drive dish milling cutter, changes the lead angle of the screw thread of institute's milling through the inclination angle of change dish milling cutter; Need not to change the screw thread that milling cutter can be processed multiple lead angle; And, can process the screw thread of big helical pitch owing to mill mode outside adopting, provide cost savings greatly.For ease of the angle of inclination of control panel milling cutter, be provided with the angle direction board at worm screw one end, the moving circle of worm screw revolution, worm gear turns over a tooth, and dish milling cutter inclination certain angle is marked at angle on the direction board by certain scale division value.
Only can use a part of worm gear during actual the use, can be a worm sector with the angle adjustment worm gear designs therefore, and the radian of said worm sector is ∏/2～∏.
The utility model needs gear-box and base are flexibly connected, and in the time of promptly need adjusting the gear-box angle, can break off and being connected of base, and after angle adjustment put in place, fixed connection again was in case be moved in milling machine operation.Those skilled in the art can adopt multiple implementation according to the effect that will reach in gear-box and being connected of base, do not enumerate one by one at this.The described gear-box of the utility model is to be fixed on the base through clamping screw.Unclamp clamping screw, get final product the turning gear roller box, after the milling cutter angle adjustment puts in place, tighten clamping screw, the fixed teeth roller box.
The utility model also comprises a spindle motor, and said spindle motor is connected with cutter spindle through reducing gear.Said reducing gear comprises that one-level is with transmission and secondary gear transmission synchronously; One-level is with the transmission input to be connected with the spindle motor output shaft synchronously; Its output is connected with the secondary gear transmission, and the output of secondary gear transmission is connected with cutter spindle through the synchromesh gear transmission.Spindle motor power is transferred to cutter spindle behind double reduction, spindle motor adopts high speed high pulling torque servomotor, can realize running up, and has improved the rotating speed of dish milling cutter, thereby has improved milling efficiency.
The utility model adopts outer milling head machining screw, can process steep-lead thread, and because the adjustable angle of dish milling cutter can realize the processing of multiple lead angle screw thread.The utility model is simple in structure, and cost is low, and is applied widely.
