Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figures 1 to 4 A waste cleaning device for a numerically controlled machine tool shown in the figure comprises a fixed frame 1, two groups of movable frames 2 are movably arranged on both sides of the fixed frame 1, a conveying assembly 3 for conveying waste is arranged in the inner cavity of the fixed frame 1, a mounting frame 4 is fixed on the top of the movable frame 2, a plurality of groups of nozzles 5 are sequentially connected to the inner cavity of the mounting frame 4, a rack plate 6 is fixed on the opposite side of the movable frame 2, the rack plate 6 is staggered up and down, and a driving adjustment assembly 7 for driving the rack plate 6 is arranged at the bottom of the fixed frame 1;

[0023] The waste transferred to the surface of the conveyor belt 33 is conveyed from the inside of the lathe to the outside through the conveying assembly 3 inside the fixed frame 1, and then the movable frame 2 can be unfolded inside the lathe and attached to the inside of the lathe to collect the waste and debris generated during the lathe processing, and then the nozzle 5 can spray cleaning liquid outward to flush the waste and debris onto the conveyor belt 33, ensuring that the waste and debris generated inside the lathe are completely cleaned.

[0024] The conveying assembly 3 includes two groups of support rollers 31 that rotate in the inner cavity of the fixed frame 1 through bearings. A driving motor 32 is fixed to the outer side of the fixed frame 1. The output shaft of the driving motor 32 is fixedly connected to one end of a group of support rollers 31. The outer side of the support rollers 31 is transmission-connected to a conveying belt 33. The inner cavity of the fixed frame 1 is rotatably connected to multiple groups of rollers 34 through bearings. The rollers 34 are located on the inner side of the conveyor belt and support the conveyor belt. A group of support rollers 31 is driven to rotate by the driving motor 32, and then cooperates with another group of support rollers 31 to drive the conveyor belt to rotate, so that waste and debris can be transferred.

[0025] The driving and adjusting assembly 7 includes two sets of supporting plates 71 fixed to the bottom of the fixed frame 1, and the opposite sides of the supporting plates 71 are rotatably connected with a rotating shaft 72 through a bearing, one end of the rotating shaft 72 passes through the supporting plate 71 and is fixed with a turning handle 73, and a gear 74 is fixed on the surface of the rotating shaft 72, and the gear 74 is located between the rack plates 6 and meshes with the rack plates 6, and the rotating shaft 72 is driven to rotate by the turning handle 73, and then the rotating shaft 72 drives the gear 74 to rotate, and the movable frames 2 on both sides are relatively moved through the rack plates 6 to adjust the fit of the movable frame 2 inside the lathe, so as to avoid gaps in the connection between the movable frame 2 and the inside of the lathe, resulting in the accumulation of a large amount of waste or debris that cannot be cleaned.

[0026] A guide groove 8 is provided at the bottom of the inner cavity of the movable frame 2, and a guide block 9 slidably connected to the guide groove 8 is fixed to the bottom of the fixed frame 1. Through the cooperation of the guide groove 8 and the guide block 9, it is convenient to limit the movable frame 2 and the fixed frame 1 to ensure relative stability between the movable frame 2 and the fixed frame 1.

[0027] The top of the nozzle 5 passes through the top of the mounting frame 4 and is connected to a fixed pipe 10. One end of the fixed pipe 10 is connected to a three-way joint 11 through a bellows. Multiple groups of nozzles 5 are connected through the fixed pipe 10, and then connected to the three-way joint 11 using the bellows, which can be telescopically adjusted in coordination with the movement of the movable frame 2.

[0028] The top of the movable frame 2 is arranged at an inclined shape, and the top of the inner cavity of the movable frame 2 is in contact with the conveyor belt.

Through the setting of the stopper 12, one end of the fixed frame 1 is conveniently blocked to prevent debris from being stuck between the fixed frame 1 and the lathe.

[0030] During specific use, the device is placed inside the lathe and below the tool. Then the handle 73 is turned to drive the rotating shaft 72 to rotate, and the gear 74 is driven to drive the rack plate 6 to move, so that the rack plate 6 drives the movable frame 2 to translate and expand inside the lathe. When the outer side of the movable frame 2 is in contact with the inner wall of the lathe, it stops. Then the three-way joint 11 is connected to the cleaning pipe, and the drive motor 32 is started at the same time. The drive motor 32 drives a group of support rollers 31 to rotate, and then drives the conveyor belt to rotate. When the lathe is processed, the waste and debris generated fall down, some of which fall directly on the conveyor belt, and some fall on the surface of the movable frame 2. At this time, the cleaning liquid is sprayed from the nozzle 5 to flush the waste and debris on the top of the movable frame 2, so that the waste and debris fall together on the conveyor belt 33, and the swing conveyor belt 33 is used to transport and transfer them to the outside of the lathe.
