Concrete meaning of the term in this utility model.
As depicted in figs. 1 and 2, cutter replacing equipment of the present utility model includes：Column 1, knife storehouse 2, the first servomotor 3, machine
Tool handss 4 and the second servomotor 5.Preferably, using the double pawl swinging mechanical hands of single armed, the two ends of mechanical hand 4 are arranged mechanical hand 4
There is paw 41；Knife storehouse 2 is collar plate shape structure.Knife storehouse 2 is arranged on the side of column 1, and mechanical hand 4 is arranged on the opposite side of column 1,
And when paw 41 rotates to the side of 2 place column 1 of knife storehouse, paw 41 can be removed cutter from knife storehouse 2 or incite somebody to action
Cutter is placed on knife storehouse 2.
With continued reference to Fig. 1 and Fig. 2, upper end (Fig. 1 and Fig. 2 shown in column 1 of first servomotor 3 installed in column 1
Upper end), and the first servomotor 3 can drive knife storehouse 2 to rotate；Top (the Fig. 1 of second servomotor 5 installed in mechanical hand 4
Upper end with mechanical hand 4 shown in Fig. 2), and the second servomotor 5 can drive mechanical hand 4 to rotate.As servomotor is adopted
It is controlled with closed loop system, i.e., servomotor possesses the function of sending pulse in itself, when servomotor receives control system
During 1 pulse for sending, the corresponding angle of 1 pulse will be rotated, so as to realize displacement, and servomotor often rotates one
Angle, can all send the pulse of respective amount so that the first servomotor 3 can control exactly knife storehouse 2 rotation angle and
Speed so that the second servomotor 5 is capable of the angle and speed of the accordingly accurately rotation of control machinery hand 4.
Preferably, first encoder (not shown) is provided with the first servomotor 3.First encoder is used for accurate
Every position cutter on ground knife edge storehouse 2, prevents position error.It is highly preferred that the first encoder is using with 23
The absolute value encoder of precision, or those skilled in the art can as the case may be using other forms and positioning precision
Encoder, as long as ensure that the cutter on knife storehouse 2 can be accurately positioned without there is random knife phenomenon.
Preferably, second encoder (not shown) is provided with the second servomotor 5.Second encoder is used for accurate
The tool change position of ground positioning mechanical arm 4, prevents mechanical hand 4 from position error occur.It is highly preferred that second encoder is adopted has 23
The absolute value encoder of position precision, or those skilled in the art can as the case may be using other forms and positioning precision
Encoder, as long as ensure mechanical hand 4 can be accurately positioned without there is knife phenomenon.
As depicted in figs. 1 and 2, screwed hole is provided with column 1 so that column 1 can be bolted numerical control machine
On bed, or those skilled in the art can also adopt other connected modes, for example, directly column 1 is fixed on ground
And make which keep a suitable distance with Digit Control Machine Tool, in order to the replacing of cutter.Further, it is additionally provided with column 1 and hangs
Ear 11, hanger 11 are used for lifting cutter replacing equipment, in order to the installation and movement of cutter replacing equipment.
In sum, when lathe needs tool changing, it is current that control system obtains target tool distance by the first encoder
The angular distance of tool change position, and then tool changing instruction is sent to the first servomotor 3 so that the first servomotor 3 is rotated forward or instead
Turn (rotating towards the less direction of target tool and tool change position angle), when target tool rotates to tool change position, first watches
Take motor 3 to stop operating；Now the second servomotor 5 drives mechanical hand 4 to rotate, when mechanical hand 4 rotates to tool change position the
Two servomotors 5 stop operating, and target tool from knife storehouse 2 is removed and firmly grasped by paw 41, and then the second servomotor 5 drives
The rotation of mechanical hand 4 makes target tool rotate to machine tool chief axis and target tool is installed on machine tool chief axis.
It will be appreciated to those of skill in the art that driving knife storehouse 2 to rotate the rotation for causing target tool to reach tool change position
It can also be one to turn direction, be controlled in order to control system.
It should be noted that the first servomotor 3 and the second servomotor 5 are from being initially rotated to stop operating, all it is logical
Cross the pulse signal that control system sends to be controlled, and the pulse signal for itself producing is fed back to control system, come with this
Knife storehouse 2 and mechanical hand 4 is made to rotate in place.First encoder is simply accurately marked the position of cutter to each on knife storehouse 2
Note, and by tool position feedback of the information to control system.Second encoder is simply accurately marked to the tool change position of mechanical hand 4
Note, and the tool change position of mechanical hand 4 is fed back to control system.Therefore, the first servomotor 3, the first encoder, the second servo
The use of motor 5 and second encoder instead of proximity switch of the prior art so that knife storehouse 2 and mechanical hand 4 are when rotated
Cutter can quickly and accurately be changed.Or those skilled in the art can also pass through the mesh on the first encoders monitor knife storehouse 2
Mark cutter rotation, in place situation, by the rotation of second encoder monitoring mechanical hand 4, in place situation.
It will be appreciated to those of skill in the art that can be controlled due to the rotating speed of servomotor, with larger torque
And preferable braking effect, so before the target tool on knife storehouse 2 reaches tool change position, the first servomotor 3 can be with
With rotational speed faster, when target tool is close to tool change position, the first servomotor 3 is slowed down again；Arrive in mechanical hand 4
Up to before tool change position, the second servomotor 5 can also with rotational speed faster, when mechanical hand 4 is close to target tool, the
Two servomotors are slowed down again.
So far, the technical solution of the utility model is described already in connection with preferred implementation shown in the drawings, but, this
Art personnel are it is easily understood that protection domain of the present utility model is expressly not limited to these specific embodiments.?
On the premise of without departing from principle of the present utility model, those skilled in the art can make the change of equivalent to correlation technique feature
Or replace, the technical scheme after these are changed or replace it is fallen within protection domain of the present utility model.
