The specific embodiment
The present invention is further described below in conjunction with accompanying drawing:
The present invention is a kind of power cutter tower angular milling header structure, is the technology that belongs to numerical-control turn-milling system example.Solved that the processing of numerical-control turn-milling end face is milled, the characteristics of boring, tapping, fraising, enhance productivity.Concealed electric main shaft and big cargo chute 22 are fixed on the lathe bed by guide rail slide block screw.It is fastening to pass through screw between power cutter tower angular milling head 21 and the power cutter tower 20, and locatees with positioning key 23.
This power cutter tower angular milling header structure feature is; Power transmission shaft 6 is fixed on the milling head housing 1 by bearing I and bearing II, and power transmission shaft 6 one ends adopt locking nut locking, and adjusting pad A compensates adjusting, is convenient to assembling.On output shaft 18, output shaft 18 is fixed on the milling head housing 1 through compressing cushion block 14 by bearing IV and bearing III by the spline positioning and fixing for bevel gear 12, and locking nut 9 is used to lock.Adjusting pad B is used for adjusting bevel gear 12 and power transmission shaft 6 gaps, and adjusting pad C and bevel gear 12 are fixed.
Be technical indicators such as the positioning accuracy that guarantees angular milling head motion process of the present invention and repetitive positioning accuracy, the present invention adopts the back-to-back layout of bearing, thereby improves the rigidity and the intensity of milling head greatly.For providing structure, the high-speed cutting of angular milling head guarantees.Through overtesting: spiral bevel gear selects that the power transmission conversion of chrysanthemum tooth is stable, response speed is fast for use.
The design satisfies the actual usefulness that needs of medium and small turning milling center, Digit Control Machine Tool, concealed electric main shaft angle body of milling head, mainly is to be connected with built-in spindle motor.Determine that from the technical parameter of milling head angular milling head power rotating speed generally changes 3000; The design is furnished with concealed electric main shaft angular milling head frame for movement, the type of belt drive maximum speed can reach 5000 changes.The structure of this high speed power cutter tower right-angle milling head is for the structural design of turning milling center Digit Control Machine Tool milling head provides thinking and the method for instructing.
The main shaft right-angle milling head adopts the form of mechanical transmission structure in this example design, and right angle main shaft milling head is passed to main shaft speed change mechanism spiral bevel gear to power by the built-in main shaft of cutter tower.Spiral bevel gear drives the processing that the cutter clamping device is finished workpiece, the main shaft milling head of this mechanical type transmission mechanism mode, be equipped with built-in spindle motor and have irreplaceable advantage: response speed has possessed high accuracy, high-speed cutting double requirements soon, simultaneously, fully satisfies the design's technical parameter requirement.
Power cutter tower angular milling head satisfies the basic function of milling head except considering principal elements such as its overall plan, version.In order to guarantee that milling machine can keep high rotating speed, high accuracy, stable operation smoothly in its design process, also takes into full account connecting form, bearing lubrication and sealing auxiliary function form and method of milling head and cutter tower.Be distributed with the cooling cannelure in the milling head housing, the heat that produces in cooling bearing and the gear movement process, make milling head keep low-temperature condition always, and then guarantee geometric accuracy and kinematic accuracy: bearing adopts grease lubrication, the periphery sealing, make bearing be in good lubricating status always, improve mechanical precision.
By to the taking all factors into consideration of main shaft milling head each side, optimize structure, realize that the mode of function reaches optimum design.Through testing: realized that angular milling greatest service energy, geometric accuracy, kinematic accuracy and stability keep good.
Embodiment recited above is described preferred implementation of the present invention; be not that design of the present invention and protection domain are limited; under the prerequisite that does not break away from design concept of the present invention; common engineers and technicians make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention.
