Specific implementation mode
As shown in Figure 1, a kind of novel tool changing device, including tool magazine 6 and cutter-exchange mechanism, tool magazine 6 are used for storing cutter and will
Specific cutter conveying displacement cutter mechanism, cutter-exchange mechanism are implemented the tool changing with machine tool chief axis and are acted.
Specifically, as shown in Figure 1 and Figure 2, cutter-exchange mechanism includes the first axle 2 for connecting connection frame 1, connection first axle 2
Tool change arm 3, rack 1 are provided with the first driving mechanism 4 and driving first axle 2 of axial movement of the driving first axle 2 along first axle 2
Second driving mechanism 5 of rotation.
As shown in figure 3, the first driving mechanism 4 includes 41 turns the first pipe fitting 41 for being set in first axle 2, driving of the first pipe fitting
Dynamic first motor 42, the controller being electrically connected with first motor 42, the first pipe fitting 41 are rotatablely connected with rack 1, the first pipe fitting
The spiral groove 44 of the ball 43 and the rolling of accommodating ball 43 of transmission is provided between 41 and first axle 2.
First motor 42 makes the first pipe fitting 41 rotate by gear or synchronous belt, and then the rolling in spiral groove 44 of ball 43
Dynamic, 43 roll drive first axle 2 of ball is moved along the axis of first axle 2, and then realizes the movement of tool change arm 3.
First pipe fitting 41, ball 43, first axle 2 be simpler than existing cam structure, light weight and occupies little space；Separately
Outside, the first pipe fitting 41, first axle 2 and ball 43 be regular shape, it is easy to process or convenient for directly purchase, it is at low cost.
First driving mechanism 4 further include the driven wheel for connecting the first pipe fitting 41, the driving wheel for connecting first motor 42, will be from
The synchronous belt that driving wheel is connect with driving wheel can be provided with retarder between first motor 42 and driving wheel, to ensure movement
Accurately.
As shown in figure 4, the second driving mechanism 5 includes 51 turns the second pipe fitting 51 for being set in first axle 2, driving of the second pipe fitting
The second dynamic motor 52, the second motor 52 are electrically connected with the controller, and the second pipe fitting 51 is rotatablely connected with rack 1, the second pipe fitting 51
It is slidably connected by keyway connection type with first axle 2.
Can multiple keys be set in the radial direction of first axle 2, to reduce drive gap, preferably spline fitted.
Second pipe fitting 51 is connect with first axle 2 by keyway, it may be convenient to first axle 2 be driven to rotate；Second pipe fitting 51
It is slidably connected with first axle 2, does not influence moving up and down for first axle 2 also.
As shown in figure 5, the alternative solution as the second driving mechanisms of Fig. 45, the second driving mechanism 5 includes being set in first
Second pipe fitting 51 of axis 2, the second motor 52 of driving the second pipe fitting 51 rotation, the second motor 52 are electrically connected with the controller, and second

Facewidth A be more than first axle 2 maximum moving distance.
The cross-wise direction of gear is parallel with the axis of first axle 2, and the facewidth A of at least one gear is more than first axle 2 most
Big displacement distance so that gear can move along the axis direction of first axle 2 while keep engaging, and the movement of first axle 2 will not
The rotation of first axle 2 is had an impact.
When cutter-exchange mechanism is run, following two patterns should be used：
1. carrying out when moving up and down of tool change arm 3, the operation of the first driving mechanism 4, the second driving mechanism 5 keeps stopping
Only, it is rotated with the first pipe fitting 41 to avoid first axle 2.
2. when carrying out the rotation of tool change arm 3, the second driving mechanism 5 operation, the first driving mechanism 4 should keep driving with second
Motivation structure 5 rotates synchronously, so that the first pipe fitting 41 does not relatively rotate with first axle 2, prevents first axle 2 from moving up and down, the
One driving mechanism 4 and the second driving mechanism 5 synchronous rotation are controlled and are compensated by controller.
The above measure is to influence each other when the first driving mechanism 4 and the second driving mechanism 5 being avoided to run.
To prevent first axle 2 and the relative rotation of the first pipe fitting 41 when tool change arm 3 rotates from first axle 2 being caused to occur up and down
It is mobile, can make first axle 2 be two parts namely first axle 2 include the first driving mechanism 4 of connection the first semiaxis and connection the
Second semiaxis of two driving mechanisms 5, the first semiaxis and the second semiaxis are rotatablely connected.First semiaxis and the second semiaxis can use end
Spherical bearing is attached, and details is not shown to be drawn.
For reduce cutter-exchange mechanism height, keep entire tool changing device compact-sized, first motor 42, the second motor 52 axis
Line and the axis of first axle 2 are arranged in parallel, the output shaft heteropleural setting of the output shaft of first motor 42 and the second motor 52, referring to
Fig. 1, Fig. 2.
When lathe space is smaller, to reduce the tool-changing mechanism size radial in first axle 2, the first pipe fitting 41 is set to the
One axis 2 is carried out with first motor 42 by shaft coupling backwards to one end of tool change arm 3, the first pipe fitting 41 backwards to the side of tool change arm 3
Connection, details is not shown to be drawn.Setting can be such that the height of tool-changing mechanism increases in this way, should be selected according to the actual arrangement of lathe.
As shown in Figure 1, Figure 7 shows, tool magazine 6 include horizontally disposed chain 62, drive chain 62 move driving gear and from
Moving gear is provided with several tool aprons 61 on chain 62, and tool apron 61 is provided with the opening of accommodating cutter.
Driving gear can be connected with motor, by motor driving driving gear rotation, and then chain 62 be made to rotate.
Due to 6 cycle rotation of chain tool magazine, it is necessary to be set to tool magazine 6, to determine the position of first cutter.
As shown in fig. 7, rack is provided with the third inductor 63 of detection 61 origin of tool apron, third inductor 63 is set to chain
The top of item 62, one in several tool aprons 61 is correspondingly arranged on the third baffle 65 coordinated with third inductor 63, third sense
Answer device 63 and third baffle 65 horizontally disposed.
When third baffle 65 is moved to tool apron 61 and chain 62 at third inductor 63, program setting can be passed through
It postpones before and after position or third baffle 65 where first cutter after several dry tool aprons 61 three baffles, 65 position
Position is the position where first cutter.
Moving cutter from tool apron 61 to cutter-exchange mechanism for convenience, the 4th induction of 61 position of rack setting detection tool apron
The fourth gear plate of device 64 and reflection 64 signal of the 4th inductor, the 4th inductor 64 and fourth gear plate are respectively arranged at tool apron 61
Top and bottom.
Due to the effect of blocking of tool apron 61,64 received signal of the 4th inductor can change, and confirm knife chain with this
Whether item 62 moves tool apron 61 in place.
Third inductor 63 and the 4th inductor 64 can be optical inductor, magnetic inductor or grating inductor, can be with
It uses as needed.
For convenience of tool changing, cutter-exchange mechanism is generally located on the straight line portion of chain 62, however cutter removes from tool apron 61
When, chain 62 can be driven to the outgoing movement of tool magazine 6, be unfavorable for the rapid disengaging of cutter and tool magazine 6, tool change time can be increased, it is right
This, the 4th plate portion 66 of the swing of restricted chain 62 is arranged in fourth gear plate, and tool apron 61 is correspondingly arranged on to abut with the 4th plate portion 66
Third plate portion.
As shown in Figure 1, Figure 7 shows, it can be adjusted to realize that tool magazine 6 deposits knife quantity, rack is provided with the tune of connection driven gear
Component 7 is saved, adjusting part 7 includes the adjustable plate 71 of strip, and one end of adjustable plate 71 is provided with to be rotatablely connected with driven gear
