[0022] Embodiment

[0023] Such as Figures 1-4 , an automatic storage protective cover, including a gantry milling machine 1, a lifting mechanism 2, and a cover member 3. The gantry milling machine 1 is arranged in the factory area. Lifting mechanisms 2 are provided on the sides of the gantry milling machine 1. A cover member 3 is provided between the two lifting mechanisms 2. The lifting mechanism 2 is used to control the lifting of the cover member 3 during the machining of the gantry milling machine 1 according to the movement trajectory of the gantry milling machine 1, so as to prevent the chips generated during the machining from splashing and injuring the operators outside.

[0024] The gantry milling machine 1 includes a bed body, a slide rail, a first milling cutter support, a second milling cutter support, and all other necessary components for the operation of the gantry milling machine 1. The slide rail is fixed on the bed body. The second milling cutter support is slidably placed on the first milling cutter support. The first milling cutter support is slidably placed on the slide rail. The milling cutter is detachably connected to the second milling cutter support. Among them, the second milling cutter support moves in the vertical direction, and the first milling cutter support moves in the horizontal direction.

[0025] The lifting mechanism 2 includes a housing 21, a shoulder rod 22, side plates 23, a lifting rod 24, and a transmission member 25. The housings 21 are respectively placed on both sides of the gantry milling machine 1. Side plates 23 are vertically slidably connected inside the housings 21. The two side plates 23 are connected by the same shoulder rod 22. The shoulder rod 22 passes through the second milling cutter support and is slidably connected to the second milling cutter support. When the second milling cutter support moves in the vertical direction, it will drive the side plates 23 to move up and down. One end of the lifting rod 24 is rotatably connected to the housing 21 and the other end is connected to the cover member 3. When machining a workpiece is required, the second milling cutter support moves down, driving the side plates 23 to move down. Through the transmission of the transmission member 25, the lifting rod 24 is lifted, causing the lifting rod 24 to move the cover member 3 to the outside of the contact point between the milling cutter and the workpiece, so as to reduce the probability of chip splashing and injuring people during the milling cutter machining.

[0026] Further, the cover member 3 includes a number of protection page monomers stacked in sequence from the inside to the outside. Adjacent protection page monomers are slidably connected. The protection page monomer located on the outermost side is fixedly connected to the bottom of the gantry milling machine 1, and the protection page monomer located on the innermost side is rotatably connected to the end of the lifting rod 24.

[0027] For example, the cover member 3 includes a first cover plate 31 and a second cover plate 32. The first cover plate 31 is fixed to the ground, the second cover plate 32 is slidably connected to the first cover plate 31, and the end of the lifting rod 24 is rotatably connected to the second cover plate 32. When the lifting rod 24 rotates, it can pull the second cover plate 32 to slide upward along the first cover plate 31, and the combination of the first cover plate 31 and the second cover plate 32 is used by unfolding, expanding the protection range of the cover member 3.

[0028] Furthermore, the transmission member 25 includes a rack 251, a gear 252, and a transmission wheel 253. The rack 251 is fixedly connected to the side plate 23, the gear 252 is rotatably connected to the housing 21, the gear 252 and the transmission wheel 253 are coaxially fixedly connected, the gear 252 and the rack 251 are in meshing transmission, and a belt pulley is fixed to the end of the lifting rod 24, and the belt pulley and the transmission wheel 253 are connected by a belt drive. In this way, when the side plate 23 drives the rack 251 to move downward, the gear 252 rotates and transmits the torque to the lifting rod 24 through the belt drive, so that the lifting rod 24 drives the cover member 3 to unfold and play a protective role.

[0029] In summary, this embodiment mainly utilizes the movement characteristic that the milling cutter needs to move downward during processing to trigger the opening of the cover member 3. When starting processing, the cover member 3 moves to the protection position and serves the purpose of protecting the operator, so that the operator does not need to automatically move to the rear side of the cover member 3, improving the practicality of the cover member 3 on this equipment.

[0030] Furthermore, in order to reduce the instability of the cover member 3 caused by the extrusion of the second milling cutter support that moves up and down repeatedly during processing on the side plate 23, damping is added to the contact surface between the lifting rod 24 and the housing 21 to reduce the sensitivity of the lifting rod 24, so that the cover body 3 gradually resets by its own gravity after processing.

[0031] A five-axis linkage CNC gantry machining center includes the above-mentioned automatic retractable protective cover.
