[0023] The following is combined with Figure 1-5 This application is described in further detail.

[0024] The present application embodiment discloses a feeding device for a CNC machine tool. Figure 1-5 A feeding device for a numerically controlled machine tool comprises a machine body 1, a first conveyor belt 5, a second conveyor belt 6 and a processing table 8. A feeding port 2 is arranged on one side outer wall of the machine body 1, and a discharging port 3 is arranged on the side outer wall of the machine body 1 away from the feeding port 2. The first conveyor belt 5 is installed inside the feeding port 2, and the second conveyor belt 6 is installed inside the discharging port 3. A supporting column 7 is fixedly connected to the inner wall of the bottom middle section of the machine body 1, and the processing table 8 is fixedly connected to the top of the supporting column 7. The processing table 8 is located between the opposite ends of the first conveyor belt 5 and the second conveyor belt 6. A plurality of conveying rollers 9 are rotatably connected to the outer wall of the top of the processing table 8 through a rotating shaft. One end of the plurality of rotating shafts passes through the processing table 8 and is fixedly connected to a rotating wheel 10. A synchronous belt 11 is installed on the outer wall of the plurality of rotating wheels 10. A driving motor 13 is fixedly installed on the outer wall of the processing table 8 through a mounting frame 12. The output shaft of the driving motor 13 is fixedly connected to one of the rotating wheels 10, and a clamping component for clamping a workpiece is installed on the inner wall of the processing table 8.

[0025] The plurality of conveying rollers 9 are evenly arranged in a linear array, and the top surfaces of the plurality of conveying rollers 9 are in the same horizontal plane as the tops of the first conveying belt 5 and the second conveying belt 6 .

[0026] The clamping assembly includes a slide groove 14 provided inside the processing table 8 , the inner wall of the slide groove 14 is rotatably connected with a bidirectional screw rod 15 , and the outer wall of the bidirectional screw rod 15 is symmetrically threadedly connected with two threaded blocks 16 .

[0027] The clamping assembly also includes two clamping plates 18 arranged above the multiple conveying rollers 9. The outer walls of the two clamping plates 18 facing away from each other are fixedly connected with connecting arms 17. The ends of the two connecting arms 17 away from the clamping plates 18 are fixedly connected to the bottom ends of the two threaded blocks 16 respectively.

[0028] A servo motor 20 is fixedly mounted on the outer wall of the middle section of one side of the processing table 8 , and the output shaft end of the servo motor 20 passes through the processing table 8 and is fixedly connected to one end of the bidirectional lead screw 15 .

[0029] Buffer pads 19 are provided on the opposite outer walls of the two clamping plates 18 .

[0030] Flexible shielding curtains 4 are installed on both side outer walls of the machine body 1 located at the feed inlet 2 and the discharge outlet 3 , and the flexible shielding curtains 4 can shield the waste chips splashed during the processing inside the machine body 1 .

[0031] The implementation principle of a CNC machine tool feeding device in an embodiment of the present application is as follows: when in use, the workpiece to be processed is placed on the first conveyor belt 5, and the first conveyor belt 5 and the second conveyor belt 6 are started. The first conveyor belt 5 transports the workpiece into the machine body 1 through the flexible shielding curtain 4. When the workpiece is transported to the processing table 8, the drive motor 13 is started, and the output shaft of the drive motor 13 drives a rotating wheel 10 to rotate, and the rotating wheel 10 drives the rotating shaft of a conveying roller 9 to rotate. At this time, multiple rotating wheels 10 realize synchronous and unidirectional rotation with the cooperation of multiple synchronous belts 11, and then multiple conveying rollers 9 rotate synchronously, and multiple conveying rollers 9 can drive the workpiece to move, and move the workpiece to the processing table 8. The middle appropriate position of the top of the table 8 is turned off at this time, and the servo motor 20 is started through the clamping assembly. The output shaft of the servo motor 20 drives the bidirectional screw 15 to rotate. When the bidirectional screw 15 rotates, the inner wall threads of the two threaded blocks 16 rotate, and then the two threaded blocks 16 are driven to move relative to each other. When the two threaded blocks 16 move relative to each other, the two connecting arms 17 are driven to approach each other, and then the two clamping plates 18 are driven by the connecting arms 17 to clamp the workpiece to fix the workpiece. When the clamping plates 18 clamp the workpiece, the two buffer pads 19 contact with the surface of the workpiece to play a buffering role to prevent the clamping force from being too large, resulting in rigid contact between the clamping plates 18 and the workpiece, causing damage to the workpiece;

[0032] After the workpiece is fixed, the machine body 1 is started, and the processing components inside the machine body 1 process the workpiece. After the processing is completed, the clamping component drives the two clamps 18 to move in opposite directions to release the fixation of the workpiece, and then the drive motor 13 is started, which drives multiple conveying rollers 9 to transport the workpiece to the surface of the second conveyor belt 6. The second conveyor belt 6 drives the processed workpiece to be unloaded from the discharge port 3 to realize the automation of feeding and discharging.
