[Prior Art] According to the continuous improvement of processing technology, the processing requirements are not only more sophisticated, but also more and more diverse for the processing type. In order to meet the needs of processing diversification, the current processing machine is generally provided. A tool magazine for storing dozens of tools, and a tool changer automatically replaces the tool between the tool magazine and the machining spindle; wherein, in addition to the general tower tool magazine, the tool magazine is developed in order to increase the amount of storage. The form of the chained magazine. The general key type tool magazine is mainly provided with a base body, and at least two sprocket wheels are pivotally arranged on the base body, and a chain frame structure formed by chain links is arranged between the sprocket wheels, and the chain frame structure is provided with several The knife sleeve positioning device has a knife sleeve clamped by each knife sleeve positioning device; the transmission chain frame structure is rotated by the sprocket wheel, and can be used to drive the knife sleeve to move to the positioning, and cooperate with the tool change device for the machining spindle operation. However, the general chain frame structure has a long distribution of the mechanism, and the knife sleeve and the cutter disposed on the knife sleeve positioning device are quite heavy, and there is no other support, guiding or limiting mechanism except the sprocket, so the chain When the frame structure is driven by the bearing sleeve, it is easy to form a sagging or slack shape due to excessive weight load. After a long time of use, it is more likely to cause interference and friction between the sprocket structure and the adjacent mechanism, and the chain frame structure is moved. When it is bumpy, swaying and not smooth, it affects the circulation of the tool magazine; in severe cases, it may even cause errors in the time and position of the 201238704 knife sleeve moving to the tool changer, resulting in reduced accuracy of the tool change operation. SUMMARY OF THE INVENTION In view of the above, the main object of the present invention is to provide a tool magazine chain frame guiding device, which can prevent the chain frame structure from swaying when moving, and at the same time improve the smoothness and smoothness of the movement, thereby ensuring the tool change and The accuracy of the closing operation. According to the above object, the tool magazine chain frame guiding device of the invention is provided with a retaining wall on the base of the tool magazine for the chain frame structure to wrap around the outer side of the retaining wall, and a driving sprocket at one end of the retaining wall. The utility model is characterized in that: the base is disposed at a position outside the retaining wall, and a first channel is disposed; and a guiding member is fixed on the end edge of the retaining wall, and the guiding member is provided with a second channel corresponding to the first channel; for guiding the chain frame structure. In the foregoing tool magazine chain frame guiding device, the base portion is disposed on the outer side of the retaining wall, and may be provided with a protruding rib, and the first channel is further opened at the edge of the protruding rib. The tool magazine chain frame guiding device, wherein the chain frame structure is formed by at least two tool holder positioning devices; the tool holder positioning device comprises two plates and a card disposed between the two plates The mast is provided with a clamping jaw on one side of the plate body, and two ends of the different sides are respectively provided with flanges, and the adjacent knife sleeve positioning device is formed by pivoting a flange to form a pivotal state. The chain shaft passes through the two ends of the flange, and is respectively provided with a sliding sleeve; the sliding sleeve can be accommodated in the first channel and the second channel. When the chain frame structure rotates around the retaining wall, the sliding sleeve can simultaneously abut the inner wall of the first channel and the second channel, and slide along the channel; thereby, the chain frame structure can be limited to the first Between the channel and the second channel, the 201238704 will not be shaken or skewed when the chain frame structure is moved; in addition, the protruding rib and the guiding member and the first channel and the second channel thereof can be supported at the same time. The weight of the chain frame structure makes the chain frame structure move more smoothly and smoothly, thereby ensuring the accuracy of tool change and closing. [Embodiment] In order to enable the reviewing committee to have a better understanding and recognition of the structural features and functions of the present invention, the following description of the preferred embodiments and the drawings is set forth below.
