[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0032] Reference Figure 1 and Figure 2 The utility model provides an embodiment: an automatic material receiving device for a CNC lathe, comprising a body 1, a fixed frame 2 is fixedly connected inside the body 1, a first motor 3 is fixedly connected to the outer wall of the fixed frame 2, a gear 1 4 is fixedly connected to the output end of the first motor 3, the gear 1 4 is rotatably connected inside the fixed frame 2, a gear 2 5 is rotatably connected inside the fixed frame 2, the gear 2 5 is meshed with the gear 1 4, a guide rail 6 is fixedly connected to the top of the gear 2 5, a slider 7 is slidably connected inside the guide rail 6, a connecting block 8 is fixedly connected to the top of the slider 7, a slide groove 9 is opened inside the fixed frame 2, the connecting block 8 is slidably connected inside the slide groove 9, a card block 10 is fixedly connected to the top of the connecting block 8, a rotating component is arranged inside the body 1, and the rotating component is used for supporting function.

[0033] Specifically, when using the CNC lathe, first place the workpiece to be processed on the outer wall of the clamping block 10, then, the output end of the first motor 3 drives the gear 1 4 to rotate inside the fixed frame 2, and the gear 1 4 drives the gear 2 5 to rotate in the same fixed frame 2 through meshing, and the operation of the gear 2 5 acts on the guide rail 6 connected at the top, and the guide rail 6 then pushes the internally connected slider 7 to slide, and the movement force of the slider 7 is transmitted to the connecting block 8 connected at the top, and slides in the slide groove 9, and the movement of the connecting block 8 finally drives the clamping block 10 connected at the top to extend outward, thereby effectively clamping and fixing the workpiece, ensuring that the workpiece is firmly fixed during the processing process.

[0034] Reference Figure 1 and Figure 4 The rotating assembly includes a support base 11, which is rotatably connected to the inside of the fixed frame 2. A second motor 12 is fixedly connected to one side of the support base 11, a worm 13 is fixedly connected to the output end of the second motor 12, one end of the worm 13 is fixedly connected to a cooling fan 14, an outer wall of the worm 13 is rotatably connected to a connecting frame 16, one side of the connecting frame 16 is fixedly connected to a connecting rod 17, one side of the connecting rod 17 is rotatably connected to a rotating rod 18, a transmission column 19 is fixedly connected to the inside of the rotating rod 18, a crank 21 is fixedly connected to the outer wall of the transmission column 19, the crank 21 is rotatably connected to one side of the connecting frame 16, one end of the transmission column 19 is fixedly connected to a worm wheel 20, and the worm wheel 20 is meshed with the worm 13.

[0035] Specifically, during the processing, the worm 13 is driven to rotate inside the connecting frame 16 by the output end of the second motor 12, and the worm 13 drives the heat dissipation fan 14 connected at one end to start rotating. Through the operation of the heat dissipation fan 14, the workpiece and the processing tool are effectively cooled down. At the same time, the rotation of the worm 13 also drives the worm gear 20 meshing therewith to rotate inside. The movement of the worm gear 20 drives the internally connected transmission column 19 to rotate. The power of the transmission column 19 is transmitted to the crank 21 connected to the outer wall, so that it rotates on one side of the connecting frame 16. The synergistic effect of the crank 21 and the transmission column 19 drives the rotating rod 18 to move, and the connecting rod 17 on one side connected to the rotating rod 18 also moves accordingly. The power of the connecting rod 17 is transmitted to the connecting frame 16, thereby causing the support seat 11 to rotate inside the machine body 1, and finally causing the worm 13 and the heat dissipation fan 14 to swing left and right, effectively realizing comprehensive cooling of the workpiece, and ensuring temperature control and processing quality during the processing.

[0036] Reference Figure 1 and Figure 3 A support platform 22 is fixedly connected to the inside of the machine body 1, a slide rail 23 is fixedly connected to the top of the support platform 22, a cylinder 24 is fixedly connected to one side of the slide rail 23, a feeding platform 15 is fixedly connected to the output end of the cylinder 24, and the feeding platform 15 is slidably connected to the outer wall of the slide rail 23.

[0037] Specifically, after the processing is completed, the workpiece is released through the clamping block 10, so that it falls safely on the feeding table 15 at the bottom. At this time, the feeding table 15 is driven to slide on the outer wall of the slide rail 23 through the output end of the cylinder 24, and the workpiece is smoothly sent out of the body 1, thereby effectively improving the unloading efficiency and ensuring easy operation and smooth production process.

[0038] Working principle: when using the CNC lathe, first place the workpiece to be processed on the outer wall of the card block 10, and then drive the gear 1 4 to rotate inside the fixed frame 2 through the output end of the first motor 3, and the gear 1 4 is forced to drive the gear 2 5 meshing with it to rotate inside the fixed frame 2, and the gear 2 5 is forced to drive the guide rail 6 connected at the top to rotate, and the guide rail 6 is forced to drive the internally connected slider 7 to slide, and the slider 7 is forced to drive the connecting block 8 connected at the top to slide inside the slide groove 9, and the connecting block 8 is forced to drive the card block 10 connected at the top to open outward, and then fix the workpiece, thereby achieving the effect of effectively fixing the workpiece, and then during the processing, the worm 13 can be driven by the output end of the second motor 12 to rotate inside the connecting frame 16, and the worm 13 is forced to drive the cooling fan 14 connected at one end to rotate, and the rotation of the cooling fan 14 can cool the workpiece and the processing tool. When the worm gear 20 is rotated, the worm gear 20 will also be driven to rotate. The worm gear 20 is driven by the force to drive the internally connected transmission column 19 to rotate. The transmission column 19 is driven by the force to drive the crank 21 connected to the outer wall to rotate on one side of the connecting frame 16, so that the crank 21 and the transmission column 19 are driven by the force to drive the rotating rod 18 to move. The rotating rod 18 is driven by the force to drive the connecting rod 17 connected to one side to move. The connecting rod 17 is driven by the force to drive the connecting frame 16 connected to one side to move. The connecting frame 16 is driven by the force to drive the support seat 11 to rotate inside the machine body 1, so that the worm 13 and the cooling fan 14 swing left and right, thereby achieving the effect of comprehensively cooling the workpiece. After the processing is completed, the workpiece is released by the clamping block 10 and falls on the feeding table 15 at the bottom. At this time, the feeding table 15 is driven by the output end of the cylinder 24 to slide on the outer wall of the slide rail 23, so that the feeding table 15 sends the workpiece out of the machine body 1, achieving the effect of facilitating unloading.
