Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and in particular to a feeding device for CNC machine tool processing. Background Technology

[0002] When a CNC machine tool is machining, it needs to transport the material to be processed through a feeding mechanism. Chinese patent publication number CN219116591U discloses a feeding device for cylindrical workpieces, including: a base with a stand; a hopper, set on the stand, with a discharge port at the upper end and two downwardly inclined bottom plates at the lower end, with a discharge port between the two bottom plates; a workpiece carrier plate, fixedly connected to the lower part of the hopper, with a groove with openings at both ends, the groove being parallel and facing the discharge port; a workpiece stopping mechanism for preventing the workpiece from falling into the discharge port; and a push rod mechanism, including a first linear drive source and a push rod, the first linear drive source being fixedly connected to the base, one end of the push rod being fixedly connected to the output end of the first linear drive source, and the other end facing the opening at one end of the groove. Used to assist robotic arms in loading workpieces, this device can transport workpieces one by one to a fixed position, ensuring that the robotic arm can grasp workpieces at the same position each time, thereby reducing the grasping error of the robotic arm. At the same time, it improves production efficiency by reducing the travel distance of the robotic arm. However, cylindrical workpieces are usually stacked together. When using the above device to grasp and load cylindrical workpieces, it is necessary to manually separate the stacked cylindrical workpieces and place them individually in order to complete the loading work, which greatly affects the work efficiency.

[0003] In view of this, the present invention proposes a feeding device for CNC machine tool processing to solve the problems existing in the prior art. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding device for CNC machine tool processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding device for CNC machine tool processing includes a placement box. An opening is provided on one outer wall of the placement box, and a guide plate is provided on one side of the opening. A separating mechanism is provided inside the opening. Two mounting plates are provided on one side of the guide plate, and two rotating rollers are rotatably connected between the two mounting plates. A conveyor belt is fitted onto the surface of the two rotating rollers, and multiple baffles are evenly spaced on the surface of the conveyor belt. A rotary motor is provided at one end of one of the rotating rollers. A notch is opened at the top of one mounting plate near the guide plate, and the inner wall of the bottom of the notch is lower than the bottom of the guide plate. The notch faces the guide plate. A T-shaped support frame is hinged to one outer wall of the bottom of the two mounting plates, and a support plate is fixedly connected to the other outer wall of the bottom of the two mounting plates. A sliding groove is opened on the outer wall of the bottom of the support plate, and a slider is slidably connected inside the sliding groove. A hydraulic rod is hinged to the outer wall of the bottom of the slider, and a base is fixedly connected to the bottom of the hydraulic rod.

[0007] Furthermore, the separating mechanism includes a receiving cavity, which is disposed above the opening, and an electromagnet is provided on the inner wall of the top of the receiving cavity. A magnetic plate is slidably connected inside the receiving cavity, and a connecting spring is fixedly connected between the magnetic plate and the electromagnet. The magnetic force generated by the electromagnet after being energized repels the magnetic plate.

[0008] Furthermore, a partition plate is slidably connected at the connection between the receiving cavity and the opening, and the top of the partition plate is fixedly connected to the bottom outer wall of the magnetic plate. The bottom of the partition plate is provided with a pointed tip, and the cross-section of the pointed tip is triangular.

[0009] Furthermore, another mounting plate has a through groove on its outer wall facing the notch, and slide rods are slidably connected to both sides of the through groove. The end of each slide rod away from the notch is fixedly connected to a limiting plate, and a connecting spring is fixedly connected between the limiting plate and the outer wall of the mounting plate.

[0010] Furthermore, the other end of the two slide rods is fixedly connected to the same pressing plate, and an air bladder is fixedly connected between the pressing plate and the through groove, with the pressing plate facing the notch.

[0011] Furthermore, a second receiving cavity is provided directly below the notch, and a delivery pipe is connected to the outer wall of the bottom of the second receiving cavity. The delivery pipe is connected to the air outlet of the airbag. A piston plate is slidably connected inside the second receiving cavity, and a connecting spring is fixedly connected between the piston plate and the inner wall of the bottom of the second receiving cavity.

[0012] Furthermore, a telescopic plate is slidably connected at the connection between the second receiving cavity and the notch, and the bottom end of the telescopic plate is fixedly connected to the top outer wall of the piston plate. When the airbag does not input gas into the second receiving cavity, the top end of the telescopic plate is lower than the bottom end of the guide plate.

[0013] Furthermore, two fixing plates are provided above the support plate, and the two fixing plates are respectively fixed on the top outer wall of the two mounting plates. A rotating shaft is rotatably connected between the two fixing plates, and a rotating motor is provided at one end of the rotating shaft. A swing plate is fixedly connected to the outer wall of the rotating shaft, and an electric push rod is embedded in the outer wall of one side of the swing plate.

[0014] Furthermore, the telescopic end of the electric push rod is fixedly connected to a lifting plate, and two fixing plates are welded to both sides of the lifting plate. A bearing roller is rotatably connected between the two fixing plates, and an electric push rod is provided directly above the bearing roller. The electric push rods are embedded in the lifting plate, and clamping plates are fixedly connected to the telescopic ends of the electric push rods.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention enables batch and individual loading of cylindrical workpieces placed in a box, facilitating CNC machine tool processing of cylindrical workpieces, greatly improving work efficiency, and avoiding the need for manual separation of stacked cylindrical workpieces in the past.

[0017] 2. When the cylindrical workpiece rolls onto the conveyor belt from under the guide plate through the notch, it will impact the extrusion plate, which will squeeze the gas in the airbag into the second receiving cavity. This will cause the telescopic plate to extend from the bottom of the notch through the piston plate, blocking the cylindrical workpiece and preventing it from leaving the conveyor belt due to the reaction force during the impact, thus affecting the feeding.

[0018] 3. When the conveyor belt tilts upwards, the cylindrical workpiece begins to detach from the conveyor belt. The bottom of the cylindrical workpiece will contact the surfaces of the two bearing rollers, so that the bearing rollers support the cylindrical workpiece. Then, the cylindrical workpiece is clamped and fixed by the clamping plate. Finally, the cylindrical workpiece is transported to the CNC machine tool by the cooperation of the second rotary motor and the first electric push rod. Attached Figure Description

[0029] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0030] Example 1, referring to Figures 1-5A feeding device for CNC machine tool processing includes a placement box 3. An opening 4 is provided on one outer wall of the placement box 3, and a guide plate 5 is provided on one side of the opening 4. A partition mechanism is provided inside the opening 4. Two mounting plates 1 are provided on one side of the guide plate 5, and two rotating rollers 11 are rotatably connected between the two mounting plates 1. A conveyor belt 9 is fitted onto the surface of the two rotating rollers 11, and multiple baffles 10 are evenly spaced on the surface of the conveyor belt 9. A rotary motor 2 is provided at one end of one of the rotating rollers 11. A notch 8 is opened at the top of one mounting plate 1 near the guide plate 5, and the inner wall of the bottom of the notch 8 is lower than that of the guide plate 5. At the bottom, notch 8 is directly opposite guide plate 5. T-shaped support frames 7 are hinged to one outer wall of the bottom of the two mounting plates 1, and support plates 6 are fixedly connected to the other outer wall of the bottom of the two mounting plates 1. A groove 15 is formed on the outer wall of the bottom of support plate 6, and a slider 14 is slidably connected inside the groove 15. A hydraulic rod 13 is hinged to the outer wall of the bottom of slider 14, and a base 12 is fixedly connected to the bottom of hydraulic rod 13. When feeding material to the CNC machine tool, the extension and retraction ends of hydraulic rod 13 are first used to move one end of the two mounting plates 1 connected to it upwards, thus tilting the two mounting plates 1. Then, the opening 4... The separating mechanism in the middle no longer blocks the opening 4, thus preventing the cylindrical workpieces piled in the box 3 from rolling out. The width of the opening 4 is slightly larger than the diameter of the cylindrical workpieces, so the cylindrical workpieces can only roll out one by one onto the guide plate 5. Because the mounting plate 1 is in an inclined state, the inclined mounting plate 1 can block the cylindrical workpieces on the guide plate 5, preventing them from rolling out to the outside. At this time, the separating mechanism is activated, thereby separating two adjacent cylindrical workpieces, so that one is on the guide plate 5 and the other is on the other side of the opening 4. After the two adjacent cylindrical workpieces are separated, the... When the hydraulic rod 13 is activated again, the two inclined mounting plates 1 are brought to a horizontal position. At this time, the notch 8 is directly opposite the guide plate 5, so that the cylindrical workpiece on the guide plate 5 can roll into the conveyor belt 9 between the two mounting plates 1 through the notch 8 and be located between the two baffles 10. Then the hydraulic rod 13 makes the mounting plates 1 tilt again, and at the same time the rotating motor 2 moves the conveyor belt 9 through the rotating roller 11. The baffles 10 on the conveyor belt 9 can prevent the cylindrical workpiece from sliding down. Under the conveying of the conveyor belt 9, the cylindrical workpiece can be transported to a certain height, which is convenient for loading onto the CNC machine tool.

[0031] As a further embodiment of the present invention, the separating mechanism includes a receiving cavity 21, which is disposed above the opening 4. An electromagnet 19 is provided on the inner wall of the top of the receiving cavity 21. A magnetic plate 18 is slidably connected inside the receiving cavity 21. A connecting spring 20 is fixedly connected between the magnetic plate 18 and the electromagnet 19. When the electromagnet 19 is energized, the magnetic force generated repels the magnetic plate 18, thereby causing the magnetic plate 18 to move downward.

[0032] As a further embodiment of the present invention, a partition plate 17 is slidably connected at the connection between the receiving cavity 21 and the through port 4, and the top of the partition plate 17 is fixedly connected to the bottom outer wall of the magnetic plate 18. The bottom of the partition plate 17 is provided with a tip 16, and the tip 16 has a triangular cross section, so that the tip 16 of the partition plate 17 can be inserted between two adjacent cylindrical workpieces to separate the two adjacent cylindrical workpieces.

[0033] Working principle: When feeding materials to a CNC machine tool, the extension end of the hydraulic rod 13 first moves one end of each of the two mounting plates 1 upwards, thus tilting the two mounting plates 1. Then, the separating mechanism in the opening 4 stops obstructing the opening, allowing the cylindrical workpieces piled in the box 3 to roll out. The width of the opening 4 is slightly larger than the diameter of the cylindrical workpieces, so the cylindrical workpieces can only roll out one by one onto the guide plate 5. Because the mounting plates 1 are tilted, they can block the cylindrical workpieces on the guide plate 5, preventing them from rolling out. At this time, the separating mechanism is activated, separating two adjacent cylindrical workpieces, allowing one to be positioned on the guide plate. On the material plate 5, another one is located on the other side of the opening 4. After the two adjacent cylindrical workpieces are separated, the hydraulic rod 13 is activated again to make the two inclined mounting plates 1 become horizontal. At this time, the notch 8 is directly opposite the guide plate 5, so the cylindrical workpiece on the guide plate 5 can roll into the conveyor belt 9 between the two mounting plates 1 through the notch 8, and is located between the two baffles 10. Then the hydraulic rod 13 makes the mounting plate 1 tilted again, and at the same time the rotating motor 2 moves the conveyor belt 9 through the rotating roller 11. The baffles 10 on the conveyor belt 9 can prevent the cylindrical workpiece from sliding down. Under the conveying of the conveyor belt 9, the cylindrical workpiece can be transported to a certain height, which is convenient for loading onto the CNC machine tool.

[0034] Example 2, refer to Figures 1-7 A feeding device for CNC machine tool processing, compared with embodiment 1, on the basis of embodiment 1, another mounting plate 1 has a through groove 24 on the outer wall facing the notch 8, and slide rods 23 are slidably connected on both sides of the through groove 24. The end of the slide rod 23 away from the notch 8 is fixedly connected to a limiting plate 26, and a connecting spring 27 is fixedly connected between the limiting plate 26 and the outer wall of the mounting plate 1.

[0035] As a further embodiment of the present invention, the outer wall of the other end of the two slide rods 23 is fixedly connected to the same pressing plate 22, and an air bag 25 is fixedly connected between the pressing plate 22 and the through groove 24. The pressing plate 22 faces the notch 8 and is located in the gap between the baffle 10 and the mounting plate 1, so it will not obstruct the movement of the baffle 10. When the cylindrical workpiece rolls from the guide plate 5 through the notch 8 onto the conveyor belt 9, it will hit the pressing plate 22 under the inertia of its own weight. After being hit, the pressing plate 22 will squeeze the air bag 25, thereby squeezing out the gas stored in the air bag 25.

[0036] As a further embodiment of the present invention, a second receiving cavity 28 is provided directly below the notch 8, and a conveying pipe 32 is connected to the bottom outer wall of the second receiving cavity 28. The conveying pipe 32 is connected to the air outlet of the airbag 25. A piston plate 29 is slidably connected inside the second receiving cavity 28, and a connecting spring 31 is fixedly connected between the piston plate 29 and the bottom inner wall of the second receiving cavity 28. The squeezed gas enters the second receiving cavity 28 through the conveying pipe 32. As the gas enters, it can push the piston plate 29 to stretch the connecting spring 31 and move it upward.

[0037] As a further embodiment of the present invention, a telescopic plate 30 is slidably connected at the connection between the second cavity 28 and the notch 8, and the bottom end of the telescopic plate 30 is fixedly connected to the top outer wall of the piston plate 29. When the airbag 25 does not input gas into the second cavity 28, the top end of the telescopic plate 30 is lower than the bottom end of the guide plate 5, thereby increasing the length of the telescopic plate 30 to block the cylindrical workpiece and prevent the cylindrical workpiece from leaving the conveyor belt 9 under the action of the reaction force during the impact, thus affecting the feeding.

[0038] Working principle: When a cylindrical workpiece rolls from the guide plate 5 through the notch 8 onto the conveyor belt 9, it will impact the pressing plate 22 due to the inertia of its own weight. The impact will compress the air bladder 25, causing the gas stored in the air bladder 25 to be squeezed out. As the gas enters, it can push the piston plate 29 to stretch the connecting spring 31 upward, thereby increasing the extension length of the telescopic plate 30, blocking the cylindrical workpiece and preventing it from leaving the conveyor belt 9 due to the reaction force during the impact, thus affecting the feeding.

[0039] Example 3, referring to Figures 1-9 A feeding device for CNC machine tool processing, compared with embodiment 2, on the basis of embodiment 2, two fixing plates 35 are provided above the support plate 6, and the two fixing plates 35 are respectively fixed on the top outer wall of the two mounting plates 1. A rotating shaft 36 is rotatably connected between the two fixing plates 35, and a rotary motor 38 is provided at one end of the rotating shaft 36. A swing plate 37 is fixedly connected to the outer wall of the rotating shaft 36, and an electric push rod 39 is embedded on one side of the outer wall of the swing plate 37.

[0040] As a further embodiment of the present invention, the telescopic end of the electric push rod 39 is fixedly connected to a lifting plate 40, and two fixing plates 34 are welded to both sides of the lifting plate 40. A bearing roller 33 is rotatably connected between the two fixing plates 34, and an electric push rod 41 is positioned directly above each bearing roller 33. The electric push rods 41 are embedded in the lifting plate 40, and clamping plates 42 are fixedly connected to the telescopic ends of the electric push rods 41. When the conveyor belt 9, along with the mounting plate 1, conveys the circular workpiece upwards, when the cylindrical workpiece begins to detach from the conveyor belt 9, the bottom of the cylindrical workpiece... The workpiece will come into contact with the surfaces of the two bearing rollers 33, so that the bearing rollers 33 can support the cylindrical workpiece. Then, the electric push rod 41 is activated, so that the clamping plate 42 is close to the bearing rollers 33, so that the cylindrical workpiece on the bearing rollers 33 can be clamped and fixed by the clamping plate 42 to prevent it from falling off during movement. Then, the rotating shaft 36 is rotated by the rotary motor 38, which can make the swing plate 37 swing. At the same time, the height of the cylindrical workpiece below the lifting plate 40 can be adjusted by the electric push rod 39, so as to facilitate the transport of the cylindrical workpiece to the CNC machine tool.

[0041] Working principle: When the conveyor belt 9 lifts up with the mounting plate 1 to transport the circular workpiece, when the cylindrical workpiece begins to detach from the conveyor belt 9, the bottom of the cylindrical workpiece will contact the surfaces of the two bearing rollers 33, so that the bearing rollers 33 support the cylindrical workpiece. Then, the electric push rod 41 is activated, which moves the clamping plate 42 close to the bearing rollers 33, thereby clamping and fixing the cylindrical workpiece on the bearing rollers 33 to prevent it from detaching during movement. Then, the rotating shaft 36 is rotated by the rotary motor 38, which makes the swing plate 37 swing. At the same time, the height of the cylindrical workpiece under the lifting plate 40 can be adjusted by the electric push rod 39, so as to facilitate the transport of the cylindrical workpiece to the CNC machine tool.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
