The above is a description of the configuration of the chain-type tool magazine 100 according to the preferred embodiment of the present application, which has the following effects.

According to the above description, each tool chain 31 has a first connecting portion 323, a right guiding portion 322, a left guiding portion 321 and a second connecting portion 324 in order along the circumference on its circumferential surface. Since the pin body 37 is pin-joined between the tool chains 31, when the chain 30 runs around, each tool chain 31 runs around with the pin body 37 as a single fulcrum. As shown in FIG. 2, the chain 30 rotates clockwise around the second rotary seat 22 and counterclockwise around the first rotary seat 21, which has the advantage of a small radius. However, the chain 30 can be lengthened appropriately to accommodate more tool holders.

Next, the second roller 322b and the third roller 322c of the chain 30 are restricted in the X direction and the Z direction at the same time by the first roller 322a of the tool chain 31, and the chain tension adjusting device 50 adjusts the chain 30 The chain 30 can run on a configuration that abuts the track 20 on one side because it helps stabilize the tension of the chain 30 .

As shown in FIG. 2 , the chain 30 rotates in contact with the first rotary seat 21 by means of the right guide portion 322 located on the tool chain 31 . The chain 30 rotates in contact with the second rotary seat 22 by means of the left guide portion 321 located on the tool chain 31 . The chains in conventional chain-type tool magazines are restricted to the right and left sides by the parallel installation of the inner and outer tracks. In comparison, in the chain 30 according to the present embodiment, the design that one side abuts against the track 20 makes it possible to run stably, reduce the track used, reduce the cost to be paid, and reduce the tool cost. The weight of the magazine can be reduced. Moreover, since the track according to the present application adopts a design in which the track is not continuous but separated (see FIG. 4), it is possible to reduce the cost of manufacturing the tool magazine. Of course, the track 20 according to the present embodiment may further include auxiliary guide rails 27 in order to increase the running stability of the chain 30 . The auxiliary guide rail 27 is attached at a specific location, for example, in the horizontal direction in which the chain 30 runs so as to support and support the chain 30, without significantly increasing the cost.

The tool sleeve 33 according to this embodiment is designed to be detachable from the connecting body 32 . The tool sleeve 33 is therefore regarded as an optional part, i.e. by exchanging a tool sleeve with a different tool placement space without changing the connecting body 32 which is connected in series and in the form of a belt: It is possible to mount and apply a large number of tool holders with different standards and dimensions. Moreover, since the tool sleeve 33 protrudes from the connecting body 32 at the rear, there is an effect that the tool locking means 34 can be inspected easily. In addition, in the sprocket 41 according to the present embodiment, the guide bush concave portions 41d of the upper rotary disc 41a and the lower rotary disc 41b respectively act on the second roller 322b and the third roller 322c positioned on the connecting body 32, so that the When the sprocket 41 rotates, since the upper and lower portions of the connecting body 32 receive a uniform force, the pin body 37 receives a uniform force indirectly, eliminating the phenomenon of excessive concentration of stress. It is possible to extend the service life of the chain 30 .
