Description

Guide tool mechanism of chain tool magazine

The present invention relates to a tool magazine of a processing machine, and more particularly to a thread guiding mechanism of a chain tool magazine.

According to the US Patent No. I322744 filed by the applicant of the case and the US patent number US7,575,543BI applied for by the same application, the name is “chain knife magazine guiding structure”, which was respectively on March 16, 2010. On August 18, 2009, the patent approval was obtained.

However, the above-mentioned "chain type tool guide structure" mainly comprises an endless belt body, a plurality of sprocket wheels for rotating the endless belt body, and a link portion of the annular belt body. The unit is configured to pivot the guiding mechanism. However, not only the structure of the guiding mechanism is too complicated, but also the manufacturing and assembly cost is high. Moreover, since the guiding mechanism drives the link unit to pivot, the sliding rail and the sliding groove are used for surface contact. Guide, so its friction is large, which requires a large driving force to drive, and its larger driving force will have the problem of excessive volume and large noise.

In view of the above, it is an object of the present invention to provide a guide tool for a chain tool magazine which is simple in structure and low in cost.

Another object of the present invention is to provide a guide tool for a chain magazine, which is less laborious and can reduce noise.

Therefore, the present invention provides a chain cutter magazine guiding mechanism, which mainly comprises: a power component; a pivoting seat having a pivoting seat body and two fins disposed on the pivoting seat body; And an arc-shaped slide rail disposed on the fins and a receiving frame coupled to the pivoting seat body, wherein the receiving frame has a pivoting space, and the fins are coupled to the power component; a pivoting guide seat having a guiding seat body and a plurality of guiding wheels disposed on the guiding seat body and alternately slidingly on opposite sides of the curved sliding rail of the pivoting seat; Therefore, the pivoting space is penetrated by a link mechanism, and the curved sliding rail of the pivoting seat is driven by the power member to slide along the guiding wheel of the pivoting guiding seat to drive the chain link. The mechanism is pivoted to achieve a simple structure, low cost, labor saving and noise reduction.

In order for your review board to have more features and characteristics of the present invention For further understanding and approval, the following preferred embodiments are listed with the following description:

Referring to FIG. 1 to FIG. 6 , a guide tool mechanism 100 of a chain tool magazine according to a preferred embodiment of the present invention is provided. The guide tool mechanism 100 of the chain magazine is disposed in a frame 91 (eg, the first As shown in the figure, the link mechanism 94 that is driven by the plurality of sprockets 92 in the frame 91 and moves along a guide inner frame 93 is turned over within a predetermined angle.

Referring to Figures 1 to 6, the chain guide mechanism 100 has a power member 10, a pivoting seat 20 and a pivoting guide 30, wherein;

Referring to FIGS. 2 and 3 , the power component 10 is a pneumatic cylinder. The power component 10 is fixed in the frame 91 by a bracket 95 . The power component 10 has a power output end 11 . The power output end 11 has a through hole 111.

Referring to FIG. 2 and FIG. 3 , the pivoting seat 20 has a pivoting seat body 21 , two fins 22 , two curved sliding rails 23 , a receiving frame 24 and a pivoting unit 25 ; 22 is disposed on the top surface of the pivoting seat body 21 at a predetermined interval, and the two fins 22 respectively have a pivot hole 221, and the two curved slide rails 23 are respectively disposed on the fins The accommodating frame 24 is disposed at a bottom position of the pivoting seat body 21, and the accommodating frame 24 has a three-sided open pivoting space 241, and the pivoting unit 25 is configured to The power output end 11 of the power component 10 is pivotally connected to the fin 22. The pivoting unit 25 has a pivoting shaft 251 and two sleeves 252. The pivoting shaft 251 The through hole 111 of the power component 10 and the pivot hole 221 of the fins 22 are respectively disposed on the pivot shaft 251 and are located on both sides of the power output end 11 . At a position, the power output end 11 of the power member 10 is pivotally connected to the fin 22 of the pivot base 20 by the pivot shaft 251, and the position of the power output end 11 can be restricted by the two sleeves 252.

Referring to FIG. 2 and FIG. 3 , the pivoting guide seat 30 is disposed in the frame body 91 . The pivoting guide seat 30 has a guiding seat body 31 and a plurality of the guiding body 31 . The guide wheels 32 are rotated in situ, and the guide wheels 32 are alternately slidably coupled to opposite sides of the curved slide rail 23 of the pivot base 20.

Therefore, the above is the introduction of each component of the guide mechanism 100 of the chain type tool magazine according to a preferred embodiment of the present invention and the assembly method thereof, and then the usage mode thereof is as follows:

When the link mechanism 94 is to be pivoted by the present invention, first, as shown in Fig. 1, the link mechanism 94 is rotated by the sprocket 92 to cause the link mechanism 94 to be pivoted. It is moved to the position of the notch 911 of one of the frames 91.

Then, the link mechanism 94 brought into the pivot space 241 can be pivoted by the guide mechanism 100 of the chain magazine of the present invention, and the pivoting manner is as follows:

The power unit 10 generates power, and the power output end 11 of the power unit 10 is biased to the pivot base 20 by the pivot unit 25 . In the above, since the curved slide rail 23 of the pivoting seat 20 is restricted by the guide wheel 32 of the pivoting guide seat 30, the pivoting seat 20 will follow the curved guide rail 23 along the guide The indexing wheel 32 pivots, so that the pivoting seat 20 can drive the link mechanism 94 entering the pivoting space 241 to pivot from the notch 911 of the frame 91 (as shown in Figures 4-6). ). After the tool change or the knife is completed by the link mechanism 94, the power member 10 is reversely biased to drive the curved slide rail 23 of the pivot base 20 to be oppositely along the pivot guide. The guide wheel 32 of 30 pivots and pivots back to a predetermined angle.

Therefore, since the guide tool device 100 of the chain type magazine of the present invention has a simple structure, the required manufacturing and assembly costs can be greatly reduced. Moreover, since the curved slide rail 23 of the pivoting seat 20 is in point contact with the guide runner 32 of the pivoting guide seat 30, the friction generated by the pivoting seat 23 is small, and not only a smaller type can be used. The power member 10 reduces the overall volume and reduces the chance of wear between the components to enhance the service life. Moreover, since the curved slide rail 23 and the guide runner 32 are in point contact, the noise can be reduced to achieve the effect of mute.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all of the related art in the art according to the present invention are equivalent to the present invention. The scope of coverage.
