Specific implementation

[0025] To make the person skilled in the art more clear and definite the technical scheme of the utility model, the utility model is described in further detail below in conjunction with examples and drawings, but the implementation of the utility model is not limited to this.

[0026] As Figures 1-6As shown, the machining center tool magazine automatic door device provided by the embodiment comprises a door frame 1, a door plate 2 which is limitingly and slidingly arranged in the door frame 1, an opening door mechanism 5 which is arranged between the door frame 1 and the door plate 2, and a track mechanism 3 which is fixed to the outer side wall of the door frame 1; the track mechanism 3 comprises a bearing plate 302 which is slidingly connected with the door frame 1 and the door plate 2, the bearing plate 302 is slidingly connected to a track groove 301 on the outer wall of the bearing plate 302, a stepping motor 305 is fixed to the outer wall of the track groove 301, a transmission assembly 304 is nested on the output end of the stepping motor 305, a lead screw 306 is driven in the other end of the transmission assembly 304, the lead screw 306 is threadedly connected with the inner wall of the bearing plate 302, and a first rack 303 is formed on the bottom wall of the bearing plate 302; the opening door mechanism 5 comprises a first driving gear 501 which is engaged with the first rack 303, a connecting rod 502 which is fixedly penetrated in the first driving gear 501, and a first worm and gear assembly 502a and a second worm and gear assembly 502b which are arranged at the outer two ends of the connecting rod 502.

[0027] In the above embodiment, the door frame 1 is internally provided with a groove for the limit sliding of the door plate 2, so that the door plate 2 can be compactly and stably slid under the driving of the opening door mechanism 5, and the sliding is prevented from being slippery, and the door plate 2 cannot be opened to affect the tool changing operation. The first rack 303 is arranged to have a length of half of the length of the bearing plate 302, when the bearing plate 302 is driven by the lead screw 306 to slide out along the groove at the bottom of the door frame 1, the first rack 303 simultaneously drives the opening door mechanism 5 to open, with the opening of the door plate 2, the tool changing robot 4 also passes through the window of the door frame 1, after the door plate 2 enters into the door frame 1, the tooth groove of the first rack 303 disappears, at this time, the bearing plate 302 continues to move until the tool changing robot 4 is parallel to the position of the tool shaft.

[0028] When the bearing plate 302 is reset, the first rack 303 is not engaged with the opening door mechanism 5, at this time, the door plate 2 is in a static state, so as to prevent the tool changing robot 4 from being interfered, when the tool changing robot 4 moves to the set position, the first rack 303 is engaged with the opening door mechanism 5, and the door plate 2 is closed in follow-up.

[0029] The track groove 301 and the outer wall of the door frame 1 are detachably installed by screws, one end of the lead screw 306 close to the transmission assembly 304 is rotationally supported by a shaft sleeve, the two sides of the shaft sleeve are fixed in the inner wall of the track groove 301, and the shaft sleeve is internally provided with a bearing, so as to rotationally support the lead screw 306 and also play a limiting role.

[0030] The tool changing robot 4 is fixedly installed at the top of the bearing plate 302, the tool changing robot 4 clamps the tool on the chain tool magazine to perform the tool changing operation.

[0031] The connecting rod 502 is rotatably mounted to the inner wall of the door frame 1. The first worm gear assembly 502a and the second worm gear assembly 502b consist of two sets of worm gears and two sets of worms. The two sets of worms are integrally connected to both ends of the connecting rod 502, and the tooth grooves of the two sets of worms are in opposite directions. The two sets of worm gears are internally rotated through a support shaft, and the two ends of the support shaft are fixed to the inner wall of the door frame 1. The tooth grooves of the worms are in opposite directions, and the worm gears that are matched and driven are also in opposite directions when driven, which can realize the opposite and opposite movement of the door panels 2.

[0032] The support shaft is also fixed with a second drive gear 503 located on both sides of the worm gear, and the second drive gear 503 rotates in the groove opened in the inner wall of the door frame 1.

[0033] The second drive gear 503 is engaged with the second rack 504 at its top, and the second rack 504 is formed at the bottom of the door panel 2.

[0034] Working principle of this device: When in use, this device is connected to the control system of the tool magazine of the machining center.

[0035] After the tool-changing robot arm 4 picks up the tool from behind the door panel 2, the stepper motor 305 drives the lead screw 306 to rotate via the transmission assembly 304, thereby driving the support plate 302 to move within the track groove 301. The support plate 302 carries the tool-changing robot arm 4 towards the door panel 2. The first rack 303 at the bottom of the support plate 302 drives the first drive gear 501 to rotate. The first drive gear 501 drives the through connecting rod 502 to rotate. The opposing first worm gear assembly 502a and second worm gear assembly 502b at both ends of the connecting rod 502 respectively drive the second worm gear assembly at the top. The drive gear 503 rotates in the opposite direction, and the second drive gear 503 meshes with the second rack 504 at the top to move the door panel 2 to separate towards each other in the inner wall of the door frame 1. As the first rack 303 disappears, the door panel 2 stops moving, and the support plate 302 continues to move forward. After the tool changing robot 4 changes the tool at the tool shaft, the stepper motor 305 rotates in the opposite direction. At this time, the first rack 303 does not engage to drive the first drive gear 501, and the door panel 2 is in a stationary state. As the first rack 303 engages, the door panel 2 moves towards each other. As the tool changing robot 4 resets, the door panel 2 completes the closing.

[0036] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
