[0017] The control mechanism 3 is located inside the rear side of the tool magazine 1, and the door opening and closing mechanism 2 is fixedly connected to the control mechanism 3. The control mechanism 3 includes a worm gear 31, a worm wheel 32, a motor 33, and a throttle 34. The worm wheel 32 is fixedly connected to the lower side of the outer arc surface of the second rotating rod 22 on the left side. The worm gear 31 is rotatably connected between the left and right inner walls of the tool magazine 1 on the lower rear side. The worm gear 31 is meshed with the worm wheel 32. The motor 33 is fixedly connected to the right side of the tool magazine 1. The output shaft of the motor 33 is fixedly connected to the right end of the worm gear 31.

Guide grooves 27 are opened at the four corners of the front side of the tool holder plate 42. The guide grooves 27 and guide bars 28 are corresponding to each other in front and back positions. A tool holder mounting bracket 6 is fixedly connected to the front side of the tool holder plate 42. A tool holder mounting bracket 5 is fixedly connected to the rear end of the tool magazine 1. When the door 25 is closed, the guide bars 28 will retract into the guide grooves 27 to maintain a sealed state.

[0019] The working principle of this utility model is as follows: When the tool magazine door structure is needed, the controller 7 can be adjusted to operate the motor 33. The output shaft of the motor 33 rotates in the forward and reverse directions, thereby driving the worm gear 32 to rotate in the forward and reverse directions, which in turn drives the second rotating rod 22 on the left to rotate in the forward and reverse directions. At this time, the quarter gear 26 on the left and the quarter gear 26 on the right maintain a meshing connection. When the second rotating rod 22 on the left rotates in both directions, the second rotating rod 22 on the right rotates in both directions, and the direction of the second rotating rod 22 on the left is opposite to that of the second rotating rod 22 on the right. When the second rotating rod 22 on the left rotates clockwise, the second rotating rod 22 on the right rotates counterclockwise. (Note that the maximum rotation angle of the first rotating rod 21 and the second rotating rod 22 is between 0 and 45°. If it exceeds 45°, it will exceed the maximum extension length of the limit telescopic rod 41. In the initial state, the limit telescopic rod 41 is in a retracted state to prevent the quarter gear 26 from disengaging.) The round pin 45 on the inclined rod 44 presses against the limit groove 43, forcing the tool holder plate 42 to move forward, which in turn drives the tool holder mounting bracket 6 on the front side of the tool holder plate 42 to move forward. At the same time, the first rotating rod 21 and the second rotating rod 22 on the left push the left door 25, causing the left door 25 to move to the left front side. At the same time, the first rotating rod 21 and the second rotating rod 22 on the right push the right door 25, causing the right door 25 to move to the right front side, opening the door 25. At this time, the tool holder on the horizontal machining center can move to the front side of the tool holder door for tool changing. If it is necessary to close the door 25, the above operation can be performed to force the door 25 to close, and the tool holder mounting bracket 6 will also retract. When the electrical appliances are powered off, the opening and closing of the storage door 25 can be manually adjusted by turning the handle 34.

[0020] It is worth noting that the quartz sand mesh size disclosed in the above embodiments is preferably between 16 and 20 mesh. The core chip of the controller 7 is a single-chip microcomputer, specifically the S7-200 model. The motor 33 can be freely configured according to the actual application scenario. It is recommended to use a 57HS22 series stepper motor for the motor 33. The controller 7 controls the operation of the motor 33 using methods commonly used in the prior art.

[0021] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
