[0116] Working principle: Refer to Figures 1 to 8 Before use, the device is installed on the CNC machine tool through the mounting hole 3, and then the distance between the loading plates 10 on both sides is adjusted according to the size of the shaft body to be processed to adapt to the shaft bodies of different sizes to be processed. Specifically, the control device 2 controls the adjustment motor 7 to start, so that the double-headed screw 8 fixedly connected to the output end of the adjustment motor 7 rotates, and the double-headed screw 8 cooperates with the threaded transmission between the two adjustment blocks 9 in the adjustment groove 4, so that the two adjustment blocks 9 are close to or away from each other in the adjustment groove 4, and then the two loading plates 10 respectively arranged on the two adjustment blocks 9 are close to or away from each other, so as to adjust the distance between the two loading plates 10;

[0117] After the distance between the two loading plates 10 is adjusted, the staff neatly stacks the shaft bodies to be processed between the two loading plates 10 (or neatly stacks the shaft bodies to be processed between the two loading plates 10 through the discharging device), and then controls the electric push rod 12 to start through the control device 2, so that the push plate 13 fixedly connected to the electric push rod 12 moves in the direction away from the C-shaped plate 11, thereby pushing the push block 15 in contact with the push plate 13 to move in the reset groove away from the C-shaped plate 11, and then pushes the shaft body close to the mounting base plate 1 onto the L-shaped plate 30, and then controls the electric push rod 12 to reset through the control device 2, and the compressed reset spring 16 releases the elastic potential energy to push the push block 15 to slide to the original position in the reset groove, preparing for pushing the shaft body to the L-shaped plate 30 next time;

[0118] After the shaft body is pushed onto the L-shaped plate 30, the hydraulic push rod 31 is controlled to start by the control device 2, so that the hydraulic push rod 31 is extended, thereby pushing the L-shaped plate 30 to move in the direction of the shaft body, until the L-shaped plates 30 on both sides are attached to the shaft body and apply corresponding force to the shaft body to clamp and fix the shaft body, and then the first motor 20 is controlled to start by the control device 2, so that the first screw 21 fixedly connected to the output end of the first motor 20 rotates, and the first slider 22 slides in the fixed frame 19 through the threaded transmission cooperation between the first screw 21 and the first slider 22, so that the first slider 22 slides in the fixed frame 19, and then the support 23 set on the first slider 22 slides with the first slider 22, so that the loading and unloading frame 24 fixedly connected to the support 23 moves, driving the hydraulic push rod 31 set on the loading and unloading frame 24 to move, so that the L-shaped plate 30 fixedly connected to the hydraulic push rod 31 moves, and then the shaft body clamped and fixed by the L-shaped plates 30 on both sides moves, until the shaft body moves to the corresponding position (the position is determined according to the size of the CNC machine tool);

[0119] After the shaft body is moved to the corresponding position, the control device 2 is used to control the loading and unloading mechanism to start, until the axis of the shaft body is lifted and lowered to coincide with the axis of the CNC machine tool chuck. The specific process is as follows: the control device 2 is used to control the second motor 26 to start, thereby rotating the second screw 27 fixedly connected to the output end of the second motor 26, and the second slider 28 is matched through the threaded transmission between the second screw 27 and the second slider 28, so that the second slider 28 slides in the loading and unloading frame 24, and then the sliding rod 29 slidably connected to the second slider 28 slides with the second slider 28, so that the L-shaped plate 30 fixedly connected to the sliding rod 29 is lifted and lowered, and then the shaft body clamped and fixed by the L-shaped plates 30 on both sides is lifted and lowered, until the axis of the shaft body is lifted and lowered to coincide with the axis of the CNC machine tool chuck;

[0120] After the axis of the shaft body is raised and lowered to coincide with the axis of the chuck of the CNC machine tool, the first motor 20 is controlled to start by the control device 2, so that the first screw 21 fixedly connected to the output end of the first motor 20 rotates, and the first slider 22 slides in the fixed frame 19 through the threaded transmission cooperation between the first screw 21 and the first slider 22, so that the support 23 set on the first slider 22 slides with the first slider 22, so that the loading and unloading frame 24 fixedly connected to the support 23 moves, driving the hydraulic push rod 31 set on the loading and unloading frame 24 to move, so that the L-shaped plate 30 fixedly connected to the hydraulic push rod 31 moves, and then drives The shaft body clamped and fixed by the L-shaped plates 30 on both sides moves until the shaft body is inserted into the chuck of the CNC machine tool, and then the second motor 26 is controlled by the control device 2 to start, thereby rotating the second screw rod 27 fixedly connected to the output end of the second motor 26, and the second slider 28 is matched with the threaded transmission between the second screw rod 27 and the second slider 28, so that the second slider 28 slides in the loading and unloading frame 24, and then the sliding rod 29 slidably connected to the second slider 28 slides with the second slider 28, so that the L-shaped plate 30 fixedly connected to the sliding rod 29 rises until the L-shaped plate 30 rises above the mounting base plate 1, thereby completing the loading of the shaft body;

[0121] After the shaft body is processed, the second motor 26 is started by the control device 2, so that the second screw 27 fixedly connected to the output end of the second motor 26 rotates, and the second slider 28 is matched by the threaded transmission between the second screw 27 and the second slider 28, so that the second slider 28 slides in the loading and unloading frame 24, so that the sliding rod 29 slidably connected to the second slider 28 slides following the second slider 28, so that the L-shaped plate 30 fixedly connected to the sliding rod 29 descends until the L-shaped plate 30 descends to the bottom of the processed shaft body, and then the first motor 20 is started by the control device 2, so that the first screw 21 fixedly connected to the output end of the first motor 20 rotates, and the first slider 22 is matched by the threaded transmission between the first screw 21 and the first slider 22, so that the first slider 22 slides in the fixed frame 19, so that the first slider 22 is set The upper support 23 slides along with the first slider 22, thereby moving the loading and unloading frame 24 fixedly connected to the support 23, thereby driving the hydraulic push rod 31 set on the loading and unloading frame 24 to move, thereby moving the L-shaped plate 30 fixedly connected to the hydraulic push rod 31 in the axial direction of the shaft body until the L-shaped plate 30 moves to the corresponding clamping position, and then the control device 2 controls the hydraulic push rod 31 to start, so that the hydraulic push rod 31 extends, thereby pushing the L-shaped plate 30 to move in the direction of the shaft body until the L-shaped plates 30 on both sides are attached to the shaft body and exert corresponding force on the shaft body to clamp and fix the shaft body, and then the control device 2 controls the first motor 20 to start, and through the transmission cooperation of a series of components, the processed shaft body clamped and fixed by the L-shaped plate 30 is removed from the chuck of the CNC machine tool, thereby completing the unloading of the processed shaft body.
