Since the automatic tool changing mechanism 70 is a known technology, it will not be repeated here.

The above is a description of the structure of the tool magazine assembly 100 according to the preferred embodiment of the present invention. The following describes that it can effectively increase the number of carrying tool pockets, and that it can improve the stability of the chain during operation.

Please refer to FIG. 5 to FIG. 7 , the knife sleeve 40 of the present embodiment is pivotally installed on one side of the chain link block 32 , and the knife sleeve 40 is placed horizontally when it is in the first position P1 . The axis L2 of the center of the knife sleeve 40 is coincident with the base line L1 of the chain link block 32 . The aforementioned structural relationship makes the knife sleeve 40 change its position with the movement of the chain 30 , and will not fold around the running path of the chain 30 . The situation of improper mutual jamming of the rotating parts improves the known patent technologies such as the above-mentioned Taiwan Announcement No. I494190 "Tool Magazine Chain Frame Guidance Device" and Announcement No. M457602 "Chain Tool Magazine for Machine Tools". Due to the fact that the knife sleeve is located on the outside of the chain (that is, the side deviating from the center of rotation), the chain can only be rotated in one direction but cannot be reversed to change the running path. Therefore, under the limited area of the main body 10 that can be loaded with the track, the tool magazine assembly of the present invention can change the running direction of the track 20 and the chain 30 arbitrarily, that is, it can be designed in a way of turning back and forth for many times. The length of the chain 30 is adjusted so that the chain 30 can carry a greater number of pockets 40 .

When the drive motor 80 drives the chain 30 to run along the track 20 through the drive wheel 82 , the first guide wheel 34 and the second guide wheel 32 of the chain link block 32 passing through the tool-taking section L of the track 20 are 36 will enter the first guide groove 24a of the first guide rail 24 and the second guide groove 26a of the second guide rail 26 as shown in FIG.

So far, the chain link block 32 Being restricted in the up, down, left, and right directions, it can move stably in the cutting section L. Even if the chain link block 32 comes to the reverse position, it is still restricted in all directions and will not be stressed on one side. At the same time, the front abutting member 46 on the knife sleeve 40 abuts against the L-shaped baffle 51a constituting the front stop member 51, so that the knife sleeve 40 will not swing downward due to its own weight. In other words, the knife sleeve retains the structure The front stop 51 of the 50 restricts the knife sleeve 40 from pivoting in the first rotation direction. It must be noted that the aforementioned first rotation direction is counterclockwise in the state shown in FIG. 5 , but when the position of the knife holder 40 is different, the first rotation direction is not necessarily the counterclockwise direction, such as FIG. 3 and FIG. 10 . As shown, the knife sleeve 40 in the horizontal section above the rail 20 has a first rotation direction in a clockwise direction because the front abutment member 46 is located below the shaft rod 54 .

When one of the chain link blocks 32 moves to the reversing position, the knife sleeve 40 pivotally connected to the chain link block 32 will correspond to the reversing pulley 64 of the reversing mechanism 60 with the guide groove 44a of the reversing sheet 44 , when the push-pull member 63 is controlled to move downward, the reverse knife pulley 64 will push the knife sleeve 40 backward to pivot in the first rotation direction, and the front abutment member 46 on the knife sleeve 40 can just pass through the gap G, Until the tool holder 40 abuts against the concave opening 55a of the bearing seat 55 and stops at the second position P2, the tool change arm 76 can smoothly grasp the tool shank T in the tool holder 40 so far.

In addition, for the chain link block 32 passing through the running section of the track 20, the first guide wheel 34 enters the guide groove 28a of the guide rail 28 to obtain the limit, and the guide rail 20 is provided with a guide at the turning point. sheet 22, so that the chain 30 can run stably. Since the chain 30 is mainly limited by the guide rails of the elongated structure, there is no need to install additional pallets on both sides of the chain 30 along the running path, so the tool of the existing chain-type tool magazine can be improved. The lack of excessive frictional force generated by the sleeve is easy to contact with the pallet, which can also effectively reduce the generation of noise. Although the rail 20 of the present embodiment is not provided with a supporting plate, and although the knife sleeve 40 located in the horizontal section above the rail 20 tends to swing downward due to its own weight, it is affected by the rear abutment of the rear end 40 b of the knife sleeve 40 . 48 abuts against the mounting plate 521 of the rear stopper 52, so as to avoid improper downward swinging of the knife sleeve 40 and maintain the horizontal swing direction of the first position P1. In other words, the rear stopper 52 in this state restricts the The knife holder 40 cannot pivot in the second rotational direction.

To sum up, the tool magazine assembly of the present invention can be designed in a more flexible manner because the rotation of the chain is no longer limited by the position of the tool pocket, which is beneficial to the increase of the number of tool pockets; in addition, the track is mainly long The guide rail of the strip structure and the guide wheel on the chain are arranged, which can improve the stability of the chain during operation. The above description is only a preferred feasible embodiment of the present invention, and all equivalent changes made by applying the description and claims of the present invention should be included in the patent scope of the present invention.
