Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically a CNC lathe with a feeding structure. Background Technology

[0002] CNC lathes are among the most widely used machining tools. They automatically process parts according to a pre-programmed machining program. They are mainly used for cutting inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of disc-shaped parts. They can also perform grooving, reaming, boring, and other machining operations.

[0003] According to a public announcement of a CNC lathe with a loading function (publication number: CN219986241U), the above application uses a drive box, a translation block, a rotating plate, an electric push rod, a mounting plate, and an electric gripper. The translation block can be moved on the drive box, and the rotating plate is rotatably mounted on the translation block. The electric push rod can drive the electric gripper to extend and retract. When loading a workpiece for processing on the CNC lathe, the rotating plate is driven to rotate, causing the electric gripper to move above the workpiece tray and clamp the workpiece. Then, the rotating plate is driven to reset, and the translation block is driven to move, which can move the electric gripper into the CNC lathe. Finally, the electric push rod can be activated to drive the electric gripper to move to the processing table, realizing automatic loading of the workpiece and improving the practicality of the CNC lathe.

[0004] However, in the aforementioned applications, electric grippers can usually only clamp and fix workpieces of specific shapes or sizes. For workpieces with complex shapes or varying sizes, their clamping effect and stability are often difficult to guarantee. Utility Model Content

[0005] The purpose of this invention is to provide a CNC lathe with a feeding structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a CNC lathe with a feeding structure, comprising a lathe body, wherein a feeding component and a limiting component are provided on the surface of the lathe body;

[0007] The feeding assembly includes:

[0008] Fixed frame one, fixed frame one is used to stabilize screw one;

[0009] Screw 1, screw 1 is used to drive screw block 1 to translate;

[0010] Screw block one, screw block one is used to drive motor two to move synchronously;

[0011] Motor 2 is used to adjust the gripping angle.

[0012] Preferably, the first fixing frame is fixed to the surface of the lathe body. A first screw is rotatably connected to the inner side of the first fixing frame. A first screw block passes through the first screw and is threadedly connected to the first screw. The first screw block is slidably connected to the inner side of the first fixing frame. A first motor is fixed to the surface of the first fixing frame. The output shaft of the first motor passes through the first fixing frame and is fixed to the surface of the first screw. A second motor is fixed to the top of the first screw block. A fixing plate is fixed to the top of the output shaft of the second motor. A second fixing frame is fixed to the end of the fixing plate away from the second motor. A second screw is rotatably connected to the inner side of the second fixing frame. A second screw block passes through the second screw and is threadedly connected to the second screw. A motor three is fixed to the surface of the fixed frame two. The output shaft of the motor three passes through the fixed frame two and is fixed to the surface of the screw two. The screw block two is slidably connected to the inside of the fixed frame two. A sliding frame is fixed to the surface of the screw block two. The feeding assembly also includes a movable part that controls the motor two to rotate forward or backward, changes the angle of the fixed plate and the fixed frame two, and controls the motor one to rotate forward or backward, which causes the screw one to rotate forward or backward, thus changing the position of the screw block one. When clamping, the motor three is turned on, the screw two rotates, and the screw block two drives the sliding frame to move closer to each other, so that the fixed rod is in contact with the surface of the workpiece. By controlling the motor one, the workpiece can be put into the lathe body, which facilitates the feeding operation.

[0013] Preferably, the movable component includes a slider, which is slidably connected to the inner side of a slide frame. A spring is fixed to the surface of the slider, and the end of the spring away from the slider is fixed to the inner side of the slide frame. A fixing rod is fixed to the end of the slider away from the spring. A clamping plate is slidably connected to the inner side of the slide frame. A screw is rotatably connected to the top of the clamping plate. The top of the screw penetrates the slide frame and is threadedly connected to the slide frame. A knob is fixed to the top of the screw. Rotating the knob causes the screw to rotate, which moves the clamping plate closer to the slider, causing the sliders to abut against each other and limit their movement. This limits the fixing rod and clamps the workpiece.

[0014] Preferably, the limiting component includes a stabilizing plate, which is fixed to the surface of the sliding frame. A sliding groove is formed on the surface of the stabilizing plate, and a locking rod is slidably connected to the inner wall of the sliding groove. A second spring is fixed to the surface of the locking rod, and the end of the second spring away from the locking rod is fixed to the inner wall of the sliding groove. A locking groove is formed on the surface of the knob. When the locking rod enters the locking groove, the knob can be limited, preventing accidents from occurring when the workpiece is moved, which could cause the knob to rotate and affect the clamping stability of the fixing rod on the workpiece.

[0015] Preferably, the second screw is provided with two opposite threads, which can make the second screw blocks move closer or further apart synchronously when the second screw rotates.

[0016] Preferably, a pull rod is fixed to the surface of the clamping rod, and the end of the pull rod away from the clamping rod passes through the stabilizing plate, so that the clamping rod can be moved easily when pulled.

[0017] Compared with the prior art, this utility model provides a CNC lathe with a feeding structure, which has the following beneficial effects:

[0018] 1. This CNC lathe with a loading structure controls the forward or reverse rotation of motor 2 via a loading component. By changing the angle of the fixed plate and fixed frame 2, and controlling the forward or reverse rotation of motor 1, the screw 1 can rotate forward or reverse, thus changing the position of screw block 1 for easy workpiece clamping. When motor 3 is turned on, screw 2 rotates, and screw block 2 drives the sliding frame to move closer together, allowing the fixed rod to fit against the workpiece surface. By controlling motor 1, the workpiece can be inserted into the lathe body for easy loading. The movable parts are designed to limit the fixed rod and prevent loosening.

[0019] 2. This CNC lathe with a loading structure uses a limit component to limit the knob by having the chuck enter the slot. This prevents accidents from happening when the workpiece is being moved, which could cause the knob to rotate and affect the clamping stability of the fixed rod on the workpiece.

[0026] like Figures 1-5 As shown, this utility model provides a technical solution: a CNC lathe with a feeding structure, including a lathe body 1, on the surface of the lathe body 1 are a feeding assembly 2 and a limiting assembly 3; the feeding assembly 2 includes: a fixed frame 20, which is used to stabilize a screw 22; a screw 22, which is used to drive a screw block 23 to move horizontally; a screw block 23, which is used to drive a motor 24 to move synchronously; and a motor 24, which is used to adjust the gripping angle. The fixed frame 20 is fixed to the surface of the lathe body 1, and the inner side of the fixed frame 20 is rotatably connected to... A screw 22 is inserted through a screw block 23, which is threadedly connected to the screw 22. The screw block 23 is slidably connected to the inside of a fixed frame 20. A motor 21 is fixed to the surface of the fixed frame 20, and the output shaft of the motor 21 passes through the fixed frame 20 and is fixed to the surface of the screw 22. A second motor 24 is fixed to the top of the screw block 23, and a fixed plate 25 is fixed to the top of the output shaft of the second motor 24. A fixed frame 26 is fixed to the end of the fixed plate 25 away from the second motor 24, and a screw 27 is rotatably connected to the inside of the fixed frame 26. Screw 27 passes through screw block 28, and screw 27 and screw block 28 are threadedly connected. Motor 3 201 is fixed to the surface of fixed frame 26. The output shaft of motor 3 201 passes through fixed frame 26 and is fixed to the surface of screw 27. Screw block 28 is slidably connected to the inside of fixed frame 26. Sliding frame 200 is fixed to the surface of screw block 28. The feeding assembly 2 also includes a movable part 29. Screw 27 is provided with two opposite threads to control motor 24 to rotate forward or backward, change the angle of fixed plate 25 and fixed frame 26, and control motor 24. 1. Rotating the screw 22 forward or backward will change the position of the screw block 23, making it easier to clamp the workpiece. When clamping, turning on the motor 201 will cause the screw 27 to rotate, which will cause the screw block 28 to drive the slide frame 200 to move closer together, so that the fixing rod 291 can be in contact with the workpiece surface. As the slide frame 200 continues to move, the fixing rod 291 can move according to the shape of the workpiece surface, so that each fixing rod 291 is in contact with the workpiece surface. By controlling the motor 21, the workpiece can be put into the lathe body 1, which facilitates the loading operation.

[0027] The movable component 29 includes a slider 290, which is slidably connected to the inner side of the slide frame 200. A spring 292 is fixed to the surface of the slider 290. The end of the spring 292 away from the slider 290 is fixed to the inner side of the slide frame 200. A fixing rod 291 is fixed to the end of the slider 290 away from the spring 292. A clamping plate 293 is slidably connected to the inner side of the slide frame 200. A screw 294 is rotatably connected to the top of the clamping plate 293. The top of the screw 294 passes through the slide frame 200 and is threadedly connected to the slide frame 200. A knob 295 is fixed to the top of the screw 294. Rotating the knob 295 causes the screw 294 to rotate, which moves the clamping plate 293 closer to the slider 290, causing the sliders 290 to abut against each other and limit their movement. This limits the fixing rod 291 and clamps the workpiece.

[0028] The limiting component 3 includes a stabilizing plate 30, which is fixed to the surface of the slide frame 200. A slide groove 31 is formed on the surface of the stabilizing plate 30. A locking rod 33 is slidably connected to the inner wall of the slide groove 31. A second spring 32 is fixed to the surface of the locking rod 33. The end of the second spring 32 away from the locking rod 33 is fixed to the inner wall of the slide groove 31. A slot 35 is formed on the surface of the knob 295. A pull rod 34 is fixed to the surface of the locking rod 33. The end of the pull rod 34 away from the locking rod 33 passes through the stabilizing plate 30. When the pull rod 34 is released, the second spring 32 is released, which drives the locking rod 33 into the slot 35, thereby limiting the knob 295 and preventing accidents from happening when the workpiece is moved, which would cause the knob 295 to rotate and affect the clamping stability of the fixing rod 291 on the workpiece.

[0029] During processing, simply place the workpiece into the lathe body 1 to begin machining. When loading is required, controlling motor 24 to rotate forward or reverse changes the angle of the fixing plate 25 and fixing frame 26. Simultaneously, controlling motor 1 to rotate forward or reverse causes screw 22 to rotate forward or reverse, changing the position of screw block 23 for easier workpiece clamping. During clamping, motor 3 201 is activated, causing screw 27 to rotate. This causes screw block 28 to move the sliding frame 200 closer together, bringing the fixing rod 291 into contact with the workpiece surface. As the sliding frame 200 continues to move, the fixing rod 291 moves according to the shape of the workpiece surface, ensuring that each fixing rod 291 is in contact with the workpiece surface. At this point, pulling pull rod 34 disengages the clamping rod 33. In slot 35, the knob 295 can be rotated normally, causing the screw 294 to rotate and move the clamping plate 293 closer to the slider 290, so that each slider 290 abuts against each other and limits the fixed rod 291, thus clamping and limiting the workpiece. At this time, the pull rod 34 is released, the spring 32 is released, and the clamping rod 33 is moved into the clamping slot 35, which limits the knob 295. This prevents accidents when moving the workpiece, which could cause the knob 295 to rotate and affect the clamping stability of the fixed rod 291. By controlling the motor 21, the workpiece can be put into the lathe body 1 for easy loading. When it is necessary to release the workpiece, the motor 201 is reversed, which causes the slide frame 200 to move the fixed rod 291 away from the workpiece, thus releasing the workpiece.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
