Above-mentioned utility model can make things convenient for the staff tool changing, but the staff tool changing is still more troublesome, and it is longer to consume time.

Disclosure of Invention

The invention aims to provide a router convenient for tool changing, and when workers need to change different milling cutter heads, the milling cutter heads can be quickly changed only by simple operation.

The technical purpose of the invention is realized by the following technical scheme:

the utility model provides a make things convenient for router of tool changing, include the shell and set firmly in the inside transmission structure of shell, transmission structure includes the numerical control motor, by numerical control motor control's milling spindle and with the shell rotate the tool magazine of being connected, the tool magazine include the center pin and with center pin fixed connection's blade disc, a plurality of logical grooves have been seted up on the blade disc, it is equipped with the external member to lead to the inslot cover, the diameter that leads to groove bottom surface opening is greater than the open-ended diameter in top, the external member is unanimous with leading to groove edge shape, the blade disc is made by iron, the external member is made by magnet, it is connected with the pneumatic cylinder to rotate on the milling spindle top, the milling spindle lower part is equipped with the external screw thread, set up the internal thread.

Through adopting above-mentioned scheme, the staff is through rotating the tool magazine, the milling cutter head that will use rotates under the milling spindle, then with the corotation of numerical control motor control milling spindle, control the milling spindle through the control pneumatic cylinder and descend, milling spindle and external member threaded connection, the dress sword has just been accomplished, just with milling spindle rebound when needing the tool changing, numerical control motor control milling spindle reversal, the external member gets into logical inslot back and the separation of milling spindle, the external member is fixed on the blade disc because the suction of magnet, then repeat above-mentioned action and can carry out the tool changing.

Preferably, a stepping motor is fixedly arranged in the shell, the stepping motor is connected with a driven rod, the tail end of the driven rod is fixedly connected with a geneva wheel mechanism, the other end of the geneva wheel mechanism is fixedly connected to the central shaft, the stepping motor drives the driven rod to rotate for one circle, and the driven rod enables the central shaft to rotate for a fixed angle through the geneva wheel mechanism.

Through adopting above-mentioned scheme, the staff control step motor rotates the center pin and need carefully adjust the angle just can let the external member just in time be located under the milling spindle, according to step motor's characteristic, the staff only need control step motor to rotate the angle that the round can let the rotatory just in time two external members of blade disc, makes the tool changing more convenient.

The workstation has been slided on the shell that corresponds the milling spindle lower extreme to the preferred, and workstation one side is equipped with the fan of blowing, and the fan of blowing is connected with the base structure, and subaerial is arranged in to the base structure, and the workstation is kept away from fan of blowing one side and is equipped with exhaust fan, and exhaust fan rigid coupling has the convulsions base, and subaerial is arranged in to the convulsions base.

Through adopting above-mentioned scheme, at router operation in-process, can produce the saw-dust when processing the plank, the saw-dust of production is blown to exhaust fan by blower, and exhaust fan takes out the saw-dust to oneself, reaches the purpose of clearance workstation.

Preferably, the air outlet of the air blower is fixedly connected with an air blowing channel, and the air blowing channel is gradually thinned from the air inlet to the air outlet.

Through adopting above-mentioned scheme, the wind that the fan of blowing blew off is through the passageway of blowing, because the passageway of blowing thins gradually, the wind pressure of the wind that blows off also strengthens gradually, and the wind that blows off is also more concentrated, strengthens the work effect of fan of blowing.

Preferably, the air draft fan is fixedly connected with an air draft cover, the lower edge of the air draft cover is equal to the length of the workbench, and an opening is formed in the bottom end of the air draft cover.
