DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Embodiment: please refer to Figs. 1 to 3 A gantry machining center protective device, comprising a rack 1, which provides support for other components in the device. The top of the rack 1 is fixed with a processing table 2, which is used to place the workpiece to be processed. The top of the processing table 2 is provided with a gantry 3, which can move along the length direction of the processing table 2. A cutting tool that can move along the width direction of the processing table 2 and can move up and down is arranged on the gantry 3, which cuts and processes the workpiece to be processed through the cutting tool. This is prior art, which will not be described here.

[0024] The embodiment also comprises a fixed protective cover 4, a lifting mechanism 5 and a movable protective cover 6.

[0025] The fixed protective cover 4 is fixed to the top of the processing table 2. The lifting mechanism 5 is arranged on the rack 1 and located below the processing table 2. The movable protective cover 6 is fixed to the movable end of the lifting mechanism 5, and the accommodation groove 7 for the movable protective cover 6 to pass through is formed on the processing table 2. The lifting mechanism 5 can drive the movable protective cover 6 to move up and down and pass through the accommodation groove 7. The movable protective cover 6 and the fixed protective cover 4 cooperate to form an annular protective structure located on the inner side of the gantry 3, so as to surround the four sides of the processing table 2 and avoid high-temperature waste scraps from splashing on the body.

[0026] In the embodiment, the fixed protective cover 4 is U-shaped, and the movable protective cover 6 is U-shaped, so as to form an annular protective structure for surrounding the four sides of the processing table 2, so that the high-temperature waste scraps are not easy to splash on the body, and at the same time, the normal movement of the cutting tool is not affected.

[0027] It should be noted that the side wall of the fixed protective cover 4 is provided with a plurality of first transparent observation windows 8, and the side wall of the movable protective cover 6 is provided with a plurality of second transparent observation windows 9, so as to facilitate observation of the machining condition of the workpiece.

[0028] In addition, the fixed protective cover 4 is provided with a splicing groove 10 on the side close to the movable protective cover 6, and the movable protective cover 6 is fixed with a splicing block 11 matched with the splicing groove 10 on the side close to the fixed protective cover 4. During the upward movement of the movable protective cover 6 driven by the lifting mechanism 5, the splicing block 11 can slide in the splicing groove 10, so that the joint of the fixed protective cover 4 and the movable protective cover 6 is more stable through the cooperation of the splicing block 11 and the splicing groove 10.

[0029] The lifting mechanism 5 is described in detail as follows:

[0030] The lifting mechanism 5 includes a supporting plate 501 symmetrically fixed to the left and right sides of the bottom of the movable protective cover 6 for supporting the movable protective cover 6. A screw sleeve 502 is fixed on each supporting plate 501, a screw rod 503 is threadedly connected with each screw sleeve 502 and is rotatably connected with the rack 1, and a first bevel gear 504 is fixed on the lower end of each screw rod 503. A double-shaft motor 505 is fixed on the rack 1, the two ends of the double-shaft motor 505 are drivingly connected with a transmission shaft 506, each transmission shaft 506 is rotatably connected with the rack 1 through the cooperation of a bearing and an axle seat, and a second bevel gear 507 is fixed on each transmission shaft 506 and is engaged with the first bevel gear 504. When the double-shaft motor 505 works, each transmission shaft 506 can be driven to rotate, so that the screw rod 503 is driven to rotate through the cooperation of the first bevel gear 504 and the second bevel gear 507, and then the supporting plate 501 is driven to move upward or downward through the cooperation of the screw rod 503 and the screw sleeve 502, so as to adjust the height of the movable protective cover 6.

[0031] In the embodiment, when the movable protective cover 6 is lowered to the limiting position, the upper end surface of the movable protective cover 6 is flush with the table surface of the machining table 2, so that the table surface of the machining table 2 is easy to clean when the table surface is cleaned. At the same time, the waste chips cannot fall to the ground or other structures through the accommodation groove 7 during the cleaning process.

[0032] The working principle is as follows:

[0033] In the normal state, the upper end surface of the movable protective cover 6 is flush with the table surface of the machining table 2, facilitating the placement of workpieces or the cleaning of the table surface of the machining table 2. When it is necessary to machine workpieces, the workpieces are placed on the machining table 2, and then the movable protective cover 6 is driven upward by the lifting mechanism 5 to the limiting position, so that the movable protective cover 6 and the fixed protective cover 4 cooperate to form an annular protective structure for surrounding the machining table 2, thereby avoiding the high-temperature waste chips from splashing onto the human body during the machining process. After the machining is completed, the movable protective cover 6 is driven downward by the lifting mechanism 5 to the limiting position, and the machined workpieces can be taken out.

[0034] It is to be understood that the terminology used herein such as first and second, etc. is only used to distinguish one entity or action from another entity or action, and does not necessarily require or imply that there is any such actual relationship or order between these entities or actions.
