Description

A kind of scalable milling cutter

Technical field

The utility model relates to lathe process field, especially a kind of scalable milling cutter.

Background technology

Along with the continuous progress of science and technology, the mankind are to the continuous lifting of the requirement that material progress is lived, and high accuracy, high efficiency and high degree of comfort become the main target of manufacture field.At present, the large-scale component of Aero-Space and civilian apparatus is all adopt disposable emptying to process, and its main processing mode is Milling Process.And, same milling plane may need out the keyway of different size, common Milling Process realizes different size keyway on same a machine tool, or expand milling scope all to need to change cutterhead, which adds the time of reorientating, too increase tool change time, serious have impact on working (machining) efficiency.The utility model devises a kind of many diameters cutterhead Integral vertical milling machine, can large velocity interval be realized by telescopic cutterhead, become size milling on same a machine tool, save the time, decreased the error because clamping again causes, substantially increase working (machining) efficiency.

Utility model content

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides the scalable milling cutter of one that a kind of structure is simple, regulate accurate positioning, reduce experimental error.

For achieving the above object, the utility model adopts following technical proposals:

A kind of scalable milling cutter, comprise main shaft, flexible cutter head and governor motion, the milling head suit that described flexible cutter head is reduced gradually by multiple size forms, and the head dummy of often kind of milling head and head dummy angle are all consistent, flexible cutter head is fixedly mounted on one end of governor motion, and the other end of governor motion is connected with milling machine, and described main shaft is hollow structure, governor motion is arranged on the inside of main shaft, and governor motion controls flexible cutter head and moves freely along major axes orientation.

Milling head on described flexible cutter head has 4, and comprise one-level milling head, secondary milling head, three grades of milling heads and level Four milling head that size sheathed successively from outside to inside reduces gradually, every grade of milling head is hollow structure.

Described governor motion comprises cylinder and push rod, described push rod is followed successively by one-level push rod, secondary push rod, three pole push rods and level Four push rod from outside to inside, one end of every grade of push rod connects the movable end of cylinder, the other end is fixedly connected with the milling head of corresponding level, and the push-pull effort of push rod at different levels acts on cutter head at different levels, make cutter head at different levels protruding or inwardly retract.

Described push rod and the movable end of cylinder are welded to connect.

The face that one end of described push rod coordinates with milling cutter is provided with screw.

The scalable milling cutter of one provided by the utility model, main shaft design, can conveniently play a protective role to adjusting device and flexible cutter head, prevents the flexible cutter head of extraneous miscellaneous part collision when stretching from causing cutter head to damage; The design of telescopic cutter head, stretching out of control cylinder can regulate required milling cutter tip when needed, save the time that staff changes milling cutter; The design of governor motion, facilitates adjusting cylinders, can be stretched out by milling cutter easily or retract, also safer.Compared with existing prior art, there is the good effect that structure is simple, easy and safe to operate, improve milling machine working (machining) efficiency.

Accompanying drawing explanation

Fig. 1, the utility model using state is illustrated;

Fig. 2, the utility model stretches cutter head upward view;

Fig. 3, the utility model governor motion structure chart.

Wherein 1 main shaft, 2 flexible cutter heads, 3 governor motions, 4 cylinders, 5 screws, 21 one-level milling heads, 22 secondary milling heads, 23 3 grades of milling heads, 24 level Four milling heads, 31 one-level push rods, 32 secondary push rods, 33 3 pole push rods, 34 level Four push rods.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Figure 1, a kind of scalable milling cutter, comprise main shaft 1, flexible cutter head 2 and governor motion 3, the milling head suit that described flexible cutter head 2 is reduced gradually by multiple size forms, and the head dummy of often kind of milling head and head dummy angle are all consistent, flexible cutter head 2 is fixedly mounted on one end of governor motion 3, the other end of governor motion 3 is connected with milling machine, described main shaft 1 is hollow structure, governor motion 3 is arranged on the inside of main shaft, main shaft design can protect governor motion, avoid the miscellaneous part collision governor motion when stretching, governor motion 3 controls various cutter head and moves freely along major axes orientation, the time of the artificial tool changing head of staff can be decreased, and safe ready, avoid injuring staff by a crashing object when changing cutter head.

As shown in Figure 2, the milling head of described flexible cutter head 2 has four, and comprise one-level milling head 21, secondary milling head 22, three grades of milling heads 23 and level Four milling head 24 that size sheathed successively from outside to inside reduces gradually, every grade of milling head is hollow structure.

As shown in Figure 3, described governor motion 3 comprises cylinder 4 and push rod, described push rod is followed successively by one-level push rod 31, secondary push rod 32, three pole push rod 33 and level Four push rod 34 from outside to inside, one end of every grade of push rod connects the movable end of cylinder, the other end is fixedly connected with the milling head of corresponding level, and the push-pull effort of push rod at different levels acts on cutter head at different levels, make cutter head at different levels protruding or inwardly retract.
