Description

Tool change arm structure capable of clamping different size cutters at both ends

The invention relates to the tool change arm of the integrated processing machine, in particular to a tool change arm structure which can hold different size handles at both ends.

Since the integrated processing machine can perform a variety of different processing, the integrated processing machine is equipped with a tool magazine. The tool between the tool magazine and the spindle head of the integrated processing machine mainly performs the work of fastening the knife and changing the tool through a tool change arm. Please refer to the figures 1 and 2, the current design of the tool changer arm, the size of the engaging portions 111, 112 at both ends cannot be changed, so the single-size tool change arm 11 can only be buckled for the single-size tool holder 12. Knife work, and the design of the tool change arm structure still has the defect of immediate improvement in the actual use situation: in order to meet the various processing methods of the integrated processing machine, the tool magazine (not shown) has various sizes and The type of cutter 13 is different, and the size of the cutter 12 for inserting the cutter 13 is also changed according to the size of the cutter 13. Therefore, the machining machine must manually replace the cutter arm while the machining operation is being performed. 11 The knives at both ends (ie, the engaging portions 111, 112) can perform the work of knives, tool changes, etc., and can perform various different processing operations, and this state not only causes the engagement of the tool change arm 11 The cumbersome replacement of the portions 111 and 112 also causes a defect in the space occupied by the engaging portions 111 and 112 of the tool change arm 11 when idle. Therefore, the above description highlights the defect that the tool change arm 11 is insufficient in applicability. .

The object of the present invention is to provide a tool changer structure capable of clamping different size handles at both ends, which mainly designs the jaw structure at both ends of the tool change arm to be movable, so that the two ends of the change arm can be clamped with different sizes.

The above description is the structure and configuration description of each main component of the embodiment of the present invention.

The mode of operation and the effect of the embodiment of the present invention are described below. Please refer to Figures 3 and 5 and refer to Figures 6, 7, and 8. It should be noted that, since the first jaw group 30 disposed on the first end portion 21 of the body 20 is operated in the same manner as the second jaw group 60 disposed on the second end portion 22 of the body 20 Therefore, only the description of the actuation of the first jaw group 30 is performed.

First, the first right clamping member 32 of the first clamping jaw group 30 is moved toward the outside of the body 20 by the first power source 81. At this time, the first right tooth of the first right clamping member 32 is disposed. When the strip 42 is interlocked, the linked first right rack 42 drives the first right gear 52 that meshes with it to rotate clockwise, and the first left gear 51 that meshes with the first right gear 52 counterclockwise. The first left gear 51 that rotates and rotates counterclockwise drives the first left rack 41 that meshes with it to move toward the outside of the body 20, and at this time, the first left side of the first left rack 41 is connected to each other. The clip member 31 is also moved toward the outside of the body 20, whereby the first left clip member 31 and the first right clip member 32 are relatively displaceable at the first end portion 21 of the body 20, and the first The left clip 31 and the first right clip 32 are spaced apart from each other, i.e., synchronously toward the outside of the body 20.

Then, when the distance between the first left clip 31 and the first right clip 32 moving toward the outside of the body 20 and the engaging portions 311, 321 conforms to the size of the pre-clamping blade 83, the first controllable A right clip 32 moves toward the inner side of the body 20, and the first right clip 32 is provided by the first right rack 42, the first right gear 52, the first left gear 51, the first left rack 41, and The first left clip 51 and the like are connected to each other in the same manner as described above, that is, the first right gear 52 rotated counterclockwise is engaged to drive the first left gear 51 to rotate clockwise, and finally the first The left clamp member 31 and the first right clamp member 32 are close to each other, that is, moved synchronously toward the inner side of the body 20.

Finally, the first left clip 31 and the engaging portions 311, 321 of the first right clip 32 that move closer to each other, that is, the handle 83 are clamped, and the action of the knife is completed.

Thereby, the present invention can respectively control the first and second left clamping members 31, 61 or the first and second right clamping members 32, 62 of the first and second clamping jaw sets 30, 60 to actuate the first clamping jaw group. The first left clip 31 of the 30 is in close proximity or disengagement with the first right clip 32, and the second left clip 61 and the second right clip 62 of the second jaw set 60 are in close proximity or Separating, so that the first and second ends 21, 22 of the body 20 can respectively clamp the handles 83, 84 of different sizes, thereby improving the applicability of the tool change arm.

It should be noted that, as shown in FIGS. 3 and 4, since the first end portion 21 of the body 20 has a first elongated hole 212, the second end portion 22 has a second elongated hole 222, and the second end portion 22 has a second elongated hole 222. The first protrusion 33 of the first right clamping member 32 slides along the first elongated hole 212, and the second protrusion 63 of the second right clamping member 62 slides along the second elongated hole 222. Therefore, the first The long hole 212 can limit the sliding distance of the first protrusion 33, and the second long hole 222 can limit the sliding distance of the second protrusion 63, thereby limiting the first left clip 31 and the first right clip. 32. The distance between the second left clip 61 and the second right clip 62 are close to each other and away from each other.

In the above, the embodiments and the drawings are only the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, that is, the equal changes and modifications made by the scope of the patent application of the present invention should be It is within the scope of the patent of the present invention.
