[0002] CNC lathe is short for numerical control lathe, which is an automated lathe equipped with a program control system. When machining products on a CNC lathe, the CNC device sends various control signals to control the lathe's movements, automatically machining the parts according to the shape and dimensions required by the drawings.

[0003] CNC lathes are mainly used for machining shaft parts such as tubes and bars. In some CNC lathes, the worker places the workpiece on the chuck of the spindle, and the chuck automatically clamps the workpiece. Then, according to a pre-programmed machining program, the workpiece is machined automatically, offering advantages such as high efficiency and high precision.

[0004] When clamping parts, the jaws on the spindle of a CNC lathe require the worker to place them accurately. Otherwise, the parts clamped by the jaws will shift, which will not only affect the machining effect but may also damage the cutting tools in severe cases. At the same time, most of the shaft parts such as pipes and bars used for machining are metal parts. Manual loading is inefficient due to the influence of physical strength, and the hands are easily cut by the cutting tools when placing the workpiece. Therefore, an automatic loading device for CNC lathes is proposed to solve the above problems. Utility Model Content

Positioning component 6 includes mounting block 61 for mounting other components. Mounting block 61 is slidably connected to the lower surface of mounting frame 41. When positioning material rod 5 with a larger diameter, the spacing of multiple sets of mounting blocks 61 can be adjusted. The inner wall of mounting block 61 is slidably connected with extrusion plate 62. Extrusion plate 62 is used for positioning material rod 5. The front surface of extrusion plate 62 is fixedly connected with connecting rod 63. Connecting rod 63 is used to connect two sets of extrusion plates 62. Extrusion plate 62 and mounting block 61 are elastically connected by spring 64. Spring 64 provides elastic force for the extension and retraction of extrusion plate 62. The outer wall of mounting block 61 is provided with elastic sheet 65 for pushing mounting block 61. The bottom of mounting block 61 is provided with pusher plate 7 for pushing material upward to a designated position.

[0033] Reference Figure 2 , Figure 4 , Figure 5The left end of the connecting plate 9 is fixedly connected to a mounting plate 11 for mounting an electric push rod 8. An electric push rod 8 for pushing a pusher plate 7 is mounted on the upper surface of the mounting plate 11. The pusher plate 7 is fixedly connected to the top of the output shaft of the electric push rod 8. The electric push rod 8 pushes the pusher plate 7 through the output shaft. The support assembly 4 also includes a motor 42 for driving a lead screw 46. The motor 42 is fixedly connected to the upper surface of the mounting frame 41. The motor 42 serves as the power source for rotating the lead screw 46. The inner wall of the mounting frame 41 has a placement groove 45 that provides sliding space for the push block 44. The inner wall of the placement groove 45 is rotatably connected to a device for moving the push block 44. The lead screw 46 is connected to the output shaft of the motor 42 via a transmission belt 43. The motor 42 is not directly connected to the lead screw 46. The outer wall of the lead screw 46 is provided with a push block 44 for pushing the material rod 5 into the main shaft. One end of the elastic plate 65 is fixedly connected to the outer wall of the mounting block 61, and the mounting block 61 provides support for the elastic plate 65.

The other end of the spring 64 is fixedly connected to the right surface of the extrusion plate 62.

[0034] Reference Figure 2 , Figure 3 , Figure 4 The pusher plate 7 is M-shaped, with edges that can block other material rods 5 and a middle that can stabilize the material rods 5 as they move vertically upward. The inner wall of the pusher plate 7 is provided with material rods 5, and the pusher plate 7 pushes the material rods 5 upward. The pusher block 44 is Z-shaped, which can push the material rods 5 when it moves along the inner wall of the mounting frame 41. The pusher block 44 is slidably connected to the inner wall of the placement groove 45, and the rear surface of the pusher block 44 contacts the outer surface of the material rods 5. The left end of the extrusion plate 62 is arc-shaped, which allows the extrusion plate 62 to extend and retract when it contacts the material rods 5. The number of extrusion plates 62 is set to multiple sets, which are fixedly connected by connecting rods 63. When the bottom extrusion plate 62 moves, it will drive the upper extrusion plate 62 to move together. The discharge plate 3 is set to an inclined state, which allows the material rods 5 to fall naturally into the pusher plate 7 by gravity.

[0035] Working principle: During use, the material bar 5 is placed into the inner wall of the feeding plate 3. Due to the inclined angle of the feeding plate 3, the material bar 5 rolls downward. When the material bar 5 falls onto the pusher plate 7, the electric push rod 8 is activated. The electric push rod 8 pushes the pusher plate 7 upward. Since the shape of the pusher plate 7 is set as M, the material bar 5 placed in the middle moves vertically upward. The edge of the pusher plate 7 blocks other material bars 5 inside the feeding plate 3. During the upward movement, the outer wall of the material bar 5 squeezes the extrusion plate 62. When the material bar 5 moves to the middle of the two sets of extrusion plates 62, the two sets of extrusion plates 62 clamp the material bar 5 together, keeping the material bar 5 aligned with the center of the lathe spindle 2. At this time, the motor 42 is activated. The motor 42 drives the lead screw 46 to rotate through the transmission belt 43. The lead screw 46 drives the pusher block 44 to move. The pusher block 44 pushes the material bar 5. The feeding work is completed when the spindle fixture clamps the material bar 5. To feed again, the above operation can be repeated. This device has better feeding stability.
