Therefore, the automatic tool change system _ change the tool can change the speed of the tool and the speed of the tool change to the scale of the machining center. The above conditions can be described as the main indicators of the design and the evaluation of the limbs. The automatic tool change system described generally includes a tool magazine for storing the tool and an exchange tool arm that simultaneously holds the tool to be removed and the tool to be mounted and converts the position to each other. In the conventional technology, the exchange knife arm generally adopts a relatively simple mechanism design; in particular, the cutter holding portion adopts a hook-shaped clip portion with a single side opening, and the hook-shaped clip portion is made by a simple embedded card structure. It is stuck with a knife seat. The biggest disadvantage of this design is that the weight of the money arm mechanism is insufficient, not only the design of the tool switching action is not precisely controlled, and its simple hook-shaped clip is easy to cause the tool to loosen and fall, in safety and reliability. There is still room for improvement: in addition, the exchange arm of the previous case cannot be fully compatible with the different rulers used in the industry (such as Japanese and American regulations). Therefore, how to develop an exchange tool arm for automatic exchange of tools, so that it can show the highest stability, safety and industrial utilization, that is, the creators of this case are dedicated. [New content] With the above requirements, this creation provides an automatic exchange tool structure; the 5 M314089 purpose and effect of this creation can be achieved in the knives and scales.

And according to the embodiment, the sensing platform can be further provided between the fixed platform (10) and the mobile platform (20); as shown in the figure, the two sensors disposed on the second sliding bar (232) (d) (d), the two sensors (251) (252) are orthogonally arranged to accurately _ the fixed platform (10) and the mobile platform (20), and the bit is provided to the mainframe of the console. - The function of the limit device ensures that the operation of the exchange tool mechanism is more precise and stable. This is in conjunction with the fourth and fifth figures, in order to say that the modified exchange arm structure provided by the present invention is 7-M314089 month w Hai's father changing tool 'mainly including one arm body (31), the arm body (31) The upper gear is pivotally disposed on the moving platform (the gear transmission mechanism of the lower moving flat ((9)) is mechanically coupled, that is, the gear box (211) can control the rotation of the arm body (31) in a parallel direction, An important basic operation for exchanging the cutter mechanism. The two ends of the arm body (31) are respectively provided with a recessed groove for accommodating a jaw (4〇) and a driving device for driving the jaw (4〇) to open and close ( 32). In this embodiment, the recessed groove may be sequentially included as a jaw slot (311) and a hydraulic cylinder slot (312) from the end side of the body; the hydraulic cylinder is embedded A hydraulic cylinder (32) is received in the groove (311) such that the driving shaft (321) of the hydraulic cylinder (32) faces the jaw insertion groove (311), and a guide block (41) is fixed to the oil. The pressure cylinder (32) drives the front of the moving shaft (321). The pair of clamping arms are the first clamping arm (42) and the third cooling arm respectively (sentence, one of the missing arms (10) (9) is the holding end (421) (431) ), and the other end is a pivot end (422) (432); each of the pivot ends (422) (432) A guide block connection hole (423) is provided, so that the first clamp arm (42) and the second clamp arm (43) are connected to the support block (423) by the pivot end (422) (432) of the support arm (423) Coincidentally, it is pivotally connected to the guide block (41) and received in the jaw slot (311) to form a movable jaw (4〇). Through the structure of the upper Chen 'When the hydraulic cylinder ( 32) When the operation is performed, the drive shaft (321) pulls the guide block (41) along with the clamp arm (42) (43) to move inside the arm body (31), and when the clamp arm (42) ( 43) When the pivot end (422) Lu (432) is blocked by the edge of the jaw slot (311), each clamp arm (42) (43) is biased inwardly to hold the end (421) (431) Relatively close, but with the function of holding a knife seat, as shown in the fifth figure. Through the above description, we should be able to understand that the automatic tool exchange structure of this creation is actually applied to the automatic tool change operation of a processing machine. Actuation mode: When the automatic tool change system is started to replace a machining tool, the automatic tool exchange structure between the machining machine and a tool magazine first drives the gear box with the motor (212) of its gear box (211). Gear driven in (211) The arm body (31) swings such that the jaws (40) at both ends of the arm body (31) respectively correspond to one of the tools below the main shaft of the processing machine and one of the tools at the tool exit of the tool magazine; the arm is activated at this time The jaw hydraulic cylinders (32) at both ends of the body (31) are such that the jaws (4〇) buckle 8: M314089 are tightly attached to the respective holders; and then the hydraulic cylinders on the fixed platform (10) are activated ( 13), the driving shaft end (13 phantom under the monitoring of the above-mentioned sensing detecting device (251) (M2), the moving platform (2 〇) is moved downward in the vertical direction, thereby acting to make the aforementioned spindle cutter And the tool to be changed synchronously generates the displacement in the vertical direction, and is separated from the original fixed position until reaching the falling position; once again, the arm gear is rotated by the gear box to a horizontal direction of 180 degrees, at this time, originally installed in The position of the tool of the spindle and the tool to be replaced is changed so that the blade scale should be processed below the machine front, and the tool originally installed in the tool now corresponds to the lower part of the tool magazine; at this time, the platform hydraulic cylinder (13) Acting for the reverse stroke, with the retraction of the drive shaft (1) again to make the $Hai mobile platform (2〇) The upper part is coupled to the fixed platform (1〇), so that the exchange tool arm (30) fixed under the fixed platform (10), together with the tool held at both ends thereof, also rises, and the tool to be changed is positioned. On the spindle, and the replaced tool can be positioned in the magazine, and the replacement of the tool is completed. The advantage of this creation is that the above design can ensure the accuracy and stability of the exchange tool arm when it is vertically and horizontally swung, and the pair of the action of the pair is unsettled and unsuitable.
