Description

Technical Field

[0001] This utility model relates to the technical field of CNC unloading mechanisms, specifically an automatic unloading mechanism for CNC. Background Technology

[0002] Numerical control machine tools, abbreviated as CNC, are automated machine tools equipped with a program control system. This control system logically processes programs with control codes or other symbolic instructions, decodes them, represents them with coded numbers, and inputs them into the numerical control unit via an information carrier. After processing, the numerical control unit sends various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings. CNC machine tools effectively solve the problems of machining complex, precise, small-batch, and multi-variety parts. They are flexible, high-efficiency automated machine tools, representing the development direction of modern machine tool control technology, and are a typical mechatronics product.

[0003] In a flexible manufacturing cell (FMC) or flexible manufacturing system (FMS), after unloading, the parts may need to be placed directly onto another conveyor belt and transported to a dedicated inspection fixture for offline inspection. The worktable of these devices is usually higher than the unloading exit, which means that operators are needed to place the parts onto another conveyor during the connection process.

[0004] Therefore, an automatic feeding mechanism for CNC is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic feeding mechanism for CNC machining, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a first feeding conveyor belt, a transfer mechanism mounted on the front of the first feeding conveyor belt, and a second feeding conveyor belt mounted on the front of the first feeding conveyor belt; The transfer mechanism includes a fixed plate, a sleeve, an electric telescopic rod, a rotating rod, a connecting rod, a pulley, and an arc-shaped groove. The fixed plate is fixedly connected to the front of the first unloading conveyor belt, and a support plate is fixedly connected to the front of the fixed plate. The sleeve is fixedly connected to the top of the support plate. The rotating rod is rotatably connected to the top of the output end of the electric telescopic rod through a bearing. The pulley is rotatably connected to the outer wall of the rotating rod through a bearing. The arc-shaped groove is formed on the outer wall of the sleeve. A clamping assembly for holding objects is assembled on the top of the connecting rod.

[0007] Preferably, the clamping assembly includes a vertical plate, a motor, and a clamping plate. The lower surface of the vertical plate is fixedly connected to the upper surface of the connecting rod. A double-ended lead screw is rotatably connected to the back of the vertical plate via a bearing. The double-ended lead screw extends movably through the vertical plate and towards the front. The motor is fixedly connected to the front of the vertical plate. The extension end of the double-ended lead screw is fixedly connected to the output end of the motor. The clamping plate is threadedly connected to the outer wall of the double-ended lead screw.

[0008] Preferably, the pulley is slidably connected to the inner wall of the arc-shaped groove.

[0009] Preferably, the top of the connecting rod has a groove for sliding the clamping plate.

[0010] Preferably, the top of the first feeding conveyor belt is equipped with a shielding mechanism.

[0011] Preferably, the blocking mechanism includes a fixed block, a T-shaped limiting block, a rack, a baffle, a limiting rod, and a spur gear. The fixed block is fixedly connected to the top of the first feeding conveyor belt. The T-shaped limiting block is fixedly connected to the front of the fixed plate. The rack is slidably connected to the outer wall of the T-shaped limiting block. The baffle is fixedly connected to the side of the rack. The limiting rod is fixedly connected to the top of the first feeding conveyor belt. The baffle is slidably connected to the outer wall of the limiting rod. The spur gear is rotatably connected to the front of the fixed block via a bearing. A drive rod is rotatably connected to the outer wall of the rotating rod. The back of the drive rod is fixedly connected to the front of the rack.

[0012] Preferably, the baffle is slidably connected to the outer wall of the limiting rod, and the two sets of racks mesh with the sprockets.

[0013] Compared with the prior art, this utility model provides an automatic feeding mechanism for CNC machining, which has the following advantages: 1. The double-headed lead screw is driven by a motor to rotate, and the clamping plate can clamp or release the object. When the object needs to be transferred, the clamping plate clamps the object, and then through the cooperation of the electric telescopic rod, rotating rod, pulley and arc groove, the object is rotated 180 degrees and moved to the top of the second feeding conveyor belt. Finally, the clamp is released and the object falls onto the conveyor belt for transfer.

[0014] Second, when the rotating rod rises, the rack and pinion drive the baffle to descend through the linkage of the drive rod, rack and pinion, thereby isolating other objects on the top of the first feeding conveyor belt. This prevents other objects on the first feeding conveyor belt from affecting the operation of the clamping components, ensuring the smooth operation of the clamping and transfer process, and avoiding clamping failure or damage to objects due to interference from other objects.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] See Figures 1-4 This embodiment provides an automatic feeding mechanism for CNC, including a first feeding conveyor belt 1, a transfer mechanism 2 mounted on the front of the first feeding conveyor belt 1, and a second feeding conveyor belt 4 mounted on the front of the first feeding conveyor belt 1. The transfer mechanism 2 includes a fixed plate 21, a sleeve 22, an electric telescopic rod 23, a rotating rod 24, a connecting rod 25, a pulley 29, and an arc groove 210. The fixed plate 21 is fixedly connected to the front of the first unloading conveyor belt 1. A support plate is fixedly connected to the front of the fixed plate 21. The sleeve 22 is fixedly connected to the top of the support plate. The rotating rod 24 is rotatably connected to the top of the output end of the electric telescopic rod 23 through a bearing. The pulley 29 is rotatably connected to the outer wall of the rotating rod 24 through a bearing. The arc groove 210 is opened on the outer wall of the sleeve 22. A clamping assembly for clamping objects is assembled on the top of the connecting rod 25.

[0019] The clamping assembly includes a vertical plate 26, a motor 27, and a clamping plate 28. The lower surface of the vertical plate 26 is fixedly connected to the upper surface of the connecting rod 25. A double-ended lead screw is rotatably connected to the back of the vertical plate 26 via a bearing. The double-ended lead screw extends movably through the vertical plate 26 to the front. The motor 27 is fixedly connected to the front of the vertical plate 26. The extension end of the double-ended lead screw is fixedly connected to the output end of the motor 27. The clamping plate 28 is threadedly connected to the outer wall of the double-ended lead screw. The thread of the double-ended lead screw is a reverse thread.

[0020] The pulley 29 is slidably connected to the inner wall of the arc-shaped groove 210.

[0021] The top of the connecting rod 25 has a groove for sliding the clamping plate 28.

[0022] In practical use, the above-mentioned equipment is activated by starting motor 27, which drives the double-ended lead screw to rotate. The double-ended lead screw drives clamping plate 28 to clamp the object. Clamping plate 28 is slidably connected to the inner wall of the slide groove, and the slide groove simultaneously limits the movement trajectory of clamping plate 28. Activating electric telescopic rod 23 drives the output end to move to the top. Electric telescopic rod 23 drives rotating rod 24 to rise. Rotating rod 24 is slidably connected to the inner wall of arc-shaped groove 210 via pulley 29. Arc-shaped groove 210 causes pulley 29 to drive rotating rod 24 to rotate. When pulley 29 slides to the highest point, pulley 29 drives rotating rod 24 to rotate 180 degrees. Rotating rod 24 drives connecting rod 2 5. When the connecting rod 25 rotates 180 degrees and the connecting rod 25 rotates 140 degrees, the height of the relative rotating rod 24 has exceeded the top of the second feeding conveyor belt 4. Because the rotation path of the connecting rod 25 is an arc, its end will gradually rise during the rotation, so that the clamped object is exactly at the top of the second feeding conveyor belt 4. Start the motor 27, and the motor 27 drives the double-headed screw to rotate. The double-headed screw drives the clamping plate 28 to release the clamp on the object, and the object falls to the top of the second feeding conveyor belt 4 for transfer. Since the rotating rod 24 is rotatably connected to the top of the output end of the electric telescopic rod 23 through the bearing, the rotating rod 24 will not affect the output end of the electric telescopic rod 23 when it rotates. Example

[0023] See Figures 1-4 Based on Embodiment 1, a shielding mechanism 3 is installed on the top of the first feeding conveyor belt 1.

[0024] The blocking mechanism 3 includes a fixed block 31, a T-shaped limiting block 32, a rack 33, a baffle 34, a limiting rod 35, and a spur gear 36. The fixed block 31 is fixedly connected to the top of the first feeding conveyor belt 1. The T-shaped limiting block 32 is fixedly connected to the front of the fixed plate 21. The rack 33 is slidably connected to the outer wall of the T-shaped limiting block 32. The baffle 34 is fixedly connected to the side of the rack 33. The limiting rod 35 is fixedly connected to the top of the first feeding conveyor belt 1. The baffle 34 is slidably connected to the outer wall of the limiting rod 35. The spur gear 36 is rotatably connected to the front of the fixed block 31 through a bearing. The outer wall of the rotating rod 24 is rotatably connected to a drive rod 37. The back of the drive rod 37 is fixedly connected to the front of the rack 33.

[0025] The baffle 34 is slidably connected to the outer wall of the limiting rod 35, and the two sets of racks 33 mesh with the spur gear 36.

[0026] In actual use, when the rotating rod 24 rises, it drives the drive rod 37 to rise, which in turn drives the rack 33 to rise. The rise of the rack 33 drives the sprocket 36 to rotate, and the sprocket 36 drives the rack 33 near the rotating rod 24 to descend. The rack 33 is slidably connected to the outer wall of the T-shaped limit block 32. The rack 33 drives the baffle 34 to descend, isolating other objects on the top of the first feeding conveyor belt 1 to prevent them from affecting the operation of the clamping components.

[0027] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
