Description

Technical Field

[0001] The present invention relates to the field of machine tool casting production, and particularly relates to a material transportation device for machine tool casting production. Background Technique

[0002] Machine tool castings refer to various metal castings used in machine tool manufacturing, mainly including components such as machine tool beds, worktables, columns, crossbeams, and gantry top connecting beams. These castings play a crucial role in the structure of machine tools, not only affecting the stability and durability of the machine tools, but also directly related to machining accuracy and efficiency. The following is an introduction to the background technique of machine tool casting production: Casting is the process of pouring molten metal liquid into a mold and obtaining parts with the required shape and performance after cooling and solidification. This technology has an important position in machine tool manufacturing because machine tool castings need to have high strength, high stiffness, excellent wear resistance, and shock absorption to meet the requirements of machine tools in high-load and high-precision machining. After the initial pouring, a large amount of sand usually adheres to the surface of the current machine tool castings, so the shakeout process must be carried out. However, after the shakeout process, the placement postures of the machine tool castings are various and cannot be directly moved to the subsequent cleaning workbench for deburring, flashing removal, and other cleaning operations. In this process, workers need to manually adjust the machine tool castings to a unified placement posture. Long-term repetitive operations will cause the workers' attention to decline, and then the placement of the machine tool castings may be disordered. This approach not only increases labor costs but also may affect the smooth progress of subsequent cleaning operations. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the background technique and propose a material transportation device for machine tool casting production.

[0004] To achieve the above object, the present invention adopts the following technical solution: A material transportation device for the production of machine tool castings, including a housing. A plurality of first springs are connected to the side wall of the inner cavity of the housing. A material placing cylinder is connected between the plurality of first springs. An inclined surface ring is fixedly sleeved on the outer peripheral wall of the material placing cylinder. A first slot is opened at the bottom of the material placing cylinder. An installation frame is welded to the bottom of the housing. An electric push rod two is elastically movably connected to the frame of the installation frame. A gasket is fixedly installed at the top telescopic end of the electric push rod two, and the gasket is located in the first slot. An electric push rod one is fixedly installed at the bottom of the inner cavity of the housing. An inner housing is fixedly installed between the top telescopic ends of the two electric push rods one. A gear ring is rotatably connected to the top of the inner cavity of the inner housing. A plurality of rotating rods are circumferentially and equally spaced and rotatably connected to the bottom of the inner cavity of the inner housing. A circular plate, a second gear, and a first push plate are welded on the outer peripheral wall of each rotating rod, and the plurality of second gears are all meshed with the gear ring. A sliding rod is welded to the top of each circular plate. A limiting plate is welded to the top of each sliding rod. A connecting plate is slidably arranged on the outer peripheral wall of each sliding rod. A second spring is wound around the outer peripheral wall of each sliding rod, and the plurality of second springs are respectively connected between the corresponding connecting plate and the limiting plate. A second push plate is welded to the side of each connecting plate away from the corresponding circular plate. A roller is rotatably connected to the bottom side of each second push plate. The electric push rod one drives the inner housing, the rotating rod, and the first push plate to move downward, so that the first push plate abuts against the bottom area of the inclined surface of the inclined surface ring. Subsequently, the motor one drives the first gear to rotate. The arranged first gear drives the gear ring to rotate. The arranged gear ring drives the second gear, the rotating rod, and the first push plate to rotate. Since the plurality of arranged first push plates face different directions, the plurality of first push plates can sequentially push the material placing cylinder to shake when rotating. In addition, since the first push plate abuts against the bottom area of the inclined surface of the inclined surface ring, the rotating first push plate performs a large-amplitude and multi-angle vibration operation on the material placing cylinder. With the vibration of the material placing cylinder, the casting connectors in the inner cavity of the material placing cylinder lie flat on the bottom of the inner cavity of the material placing cylinder.

[0005] In the above-mentioned material transportation device for the production of machine tool castings, a plurality of second slots are circumferentially and equally spaced on the outer peripheral wall of the material placing cylinder, and the second push plate passes through the second slot and extends into the inner cavity of the material placing cylinder.

[0006] In the above-mentioned material transportation device for the production of machine tool castings, a plurality of third slots are circumferentially and equally spaced on the outer peripheral wall of the material placing cylinder. An annular aggregate box is fixedly installed at the bottom of the inner cavity of the housing. A small amount of sand adheres to the surface of the casting connector after the sand has fallen off. During the above vibration process, the small amount of sand adhering to the surface of the casting connector shakes off under the action of vibration. Since the central area at the bottom of the inner cavity of the material placing cylinder bulges slightly, the shaken sand slides along the inclined surface of the bottom of the inner cavity of the material placing cylinder towards the edge of the bottom of the inner cavity of the material placing cylinder, and finally the sand further slides into the annular aggregate box through the third slot, thereby realizing the cleaning and collection of the sand.

[0007] In the above-mentioned material transportation device for machine tool casting production, a first motor is fixedly installed at the bottom of the inner cavity of the outer shell, and a first gear meshing with the gear ring is fixedly installed on the top of the first motor. The first motor is arranged to drive the first gear to rotate, and the first gear is arranged to drive the gear ring to rotate.

[0008] In the above-mentioned material transportation device for machine tool casting production, an annular sliding groove is formed at the top of the inner cavity of the inner shell, and an annular sliding block slidably arranged inside the annular sliding groove is welded to the top of the gear ring.

[0009] In the above-mentioned material transportation device for machine tool casting production, a second motor is fixedly installed on one side of the top of each of several second push plates, and the output ends of the several second motors are respectively fixedly installed with corresponding rollers. The second motors are arranged to drive the rollers to rotate.

[0010] In the above-mentioned material transportation device for machine tool casting production, two cross plates are welded on the outer peripheral wall of the outer shell, and fixing holes are formed at the tops of the two cross plates. The cross plates and the fixing holes are arranged to facilitate the fixed installation of the device main body at a specific position.

[0011] Compared with the existing technology, the advantages of the material transportation device for machine tool casting production of the present invention are as follows:

[0012] 1. The first electric push rod drives the inner shell, the rotating rod and the first push plate to move downward. Since the several first push plates are arranged in different directions, when the several first push plates rotate, they can sequentially push the material placing cylinder to shake. In addition, since the first push plate abuts against the bottom area of the inclined surface of the inclined surface ring, the rotating first push plate performs a large-amplitude and multi-angle vibration operation on the material placing cylinder. With the vibration of the material placing cylinder, the casting connecting parts in the inner cavity of the material placing cylinder lie flat at the bottom of the inner cavity of the material placing cylinder.

[0013] 2. A small amount of sand adheres to the surface of the casting connecting parts after sand falling. During the above vibration process, the small amount of sand adhering to the surface of the casting connecting parts shakes off under the action of vibration. Since the central area at the bottom of the inner cavity of the material placing cylinder bulges slightly, the shaken sand slides along the inclined surface at the bottom of the inner cavity of the material placing cylinder towards the edge of the bottom of the inner cavity of the material placing cylinder, and finally the sand further slides into the annular aggregate box through the third slot hole, thereby realizing the cleaning and collection of the sand.

[0014] 3. The first electric push rod drives the inner shell, the rotating rod and the first push plate to move downward, and then the motor drives the first push plate to rotate. Since the first push plate abuts against the top area of the inclined surface of the inclined surface ring, the rotating first push plate performs a small-amplitude and multi-angle vibration operation on the material placing cylinder, thereby promoting the casting connecting parts to break free from the first slot hole.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0027] Reference Figures 1-9 , a material transportation device for the production of machine tool castings, including a housing 1. A number of first springs 2 are connected to the inner side wall of the housing 1 cavity. A material placing cylinder 3 is connected between the number of first springs 2. An inclined surface ring 4 is fixedly sleeved on the outer peripheral wall of the material placing cylinder 3. An electric push rod 9 is fixedly installed at the bottom of the housing 1 cavity. An inner housing 10 is fixedly installed between the telescopic ends of the two electric push rods 9 at the top. A gear ring 11 is rotatably connected to the top of the inner housing 10 cavity. An annular sliding groove is opened at the top of the inner housing 10 cavity. An annular slider that is welded to the top of the gear ring 11 and slidably arranged inside the annular sliding groove. A first motor 25 is fixedly installed at the bottom of the housing 1 cavity. A first gear 26 that meshes with the gear ring 11 is fixedly installed at the top of the first motor 25. A number of rotating rods 12 are circumferentially and rotatably connected to the bottom of the inner housing 10 cavity at equal intervals. A circular plate 13, a second gear 14 and a first push plate 15 are welded on the outer peripheral wall of each rotating rod 12. And a number of second gears 14 are all meshed with the gear ring 11. The casting connectors 30 that have completed the shakeout process are sequentially dropped into the cavity of the material placing cylinder 3. Subsequently, the electric push rod 9 drives the inner housing 10, the rotating rod 12 and the first push plate 15 to move downward, so that the first push plate abuts against the bottom area of the inclined surface of the inclined surface ring 4. Subsequently, the first motor 25 drives the first gear 26 to rotate. The provided first gear 26 drives the gear ring 11 to rotate. The provided gear ring 11 drives the second gears 14, the rotating rod 12 and the first push plate 15 to rotate. Since the directions of the number of first push plates 15 are different, the number of first push plates 15 can sequentially push the material placing cylinder 3 to shake when rotating. In addition, since the first push plate 15 abuts against the bottom area of the inclined surface of the inclined surface ring 4, the rotating first push plate 15 performs a large-amplitude and multi-angle vibration operation on the material placing cylinder 3. With the vibration of the material placing cylinder 3, the casting connectors 30 in the cavity of the material placing cylinder 3 lie flat on the bottom of the cavity of the material placing cylinder 3.

[0028] Furthermore, a number of slot holes 23 are circumferentially opened at equal intervals on the outer peripheral wall of the material placing cylinder 3. An annular aggregate box 24 is fixedly installed at the bottom of the housing 1 cavity. A small amount of sand adheres to the surface of the casting connectors 30 after shakeout. During the above vibration process, the small amount of sand adhering to the surface of the casting connectors 30 shakes off under the action of vibration. Since the central area at the bottom of the cavity of the material placing cylinder 3 bulges slightly, the shaken sand slides along the inclined surface at the bottom of the cavity of the material placing cylinder 3 towards the edge of the bottom of the cavity of the material placing cylinder 3. Finally, the sand further slides into the annular aggregate box 24 through the slot holes 23, thereby realizing the cleaning and collection of the sand.

[0029] Further, a slide bar 16 is welded to the top of each circular plate 13, a limiting plate 17 is welded to the top of each slide bar 16, a connecting plate 18 is slidably arranged on the outer peripheral wall of each slide bar 16, a second spring 19 is wound around the outer peripheral wall of each slide bar 16, and several second springs 19 are respectively connected between the corresponding connecting plate 18 and the limiting plate 17. A second push plate 20 is welded to the side of each connecting plate 18 away from the corresponding circular plate 13. A number of second slot holes 22 are equidistantly and circumferentially formed in the outer peripheral wall of the material placing cylinder 3, and the second push plate 20 passes through the second slot hole 22 and extends into the inner cavity of the material placing cylinder 3. A roller 21 is rotatably connected to one side of the bottom of each second push plate 20. A number of second motors 27 are fixedly installed on one side of the top of the second push plates 20, and the output ends of the second motors 27 are respectively fixedly installed with the corresponding rollers 21. Subsequently, the first electric push rod 9 drives the inner shell 10, the rotating rod 12 and the first push plate 15 to reset upward. At this time, the second push plate 20 provided is located on the same horizontal line as the second slot hole 22 formed in the side wall of the material placing cylinder 3. Subsequently, the first motor 25 drives the first gear 26 to rotate. The first gear 26 provided drives the toothed ring 11 to rotate. The toothed ring 11 provided drives the second gear 14, the rotating rod 12 and the second push plate 20 to rotate. The rotating second push plate 20 pushes the casting connector 30 to the central position at the bottom of the inner cavity of the material placing cylinder 3, thereby realizing the centering effect of the casting connector 30. A first slot hole 5 is formed at the bottom of the material placing cylinder 3. An installation frame 6 is welded to the outer peripheral wall of the outer shell 1. An electric push rod 7 is elastically and movably connected to the frame of the installation frame 6. A gasket 8 is fixedly installed at the telescopic end of the top of the electric push rod 7, and the gasket 8 is located in the first slot hole 5. Subsequently, the electric push rod 7 drives the gasket 8 to move downward. The gasket 8 provided moves out of the first slot hole 5. It should be noted that the top plane of the gasket 8 after moving downward is located on the same horizontal line as the bottom plane of the material placing cylinder 3. Subsequently, the first electric push rod 9 drives the second push plate 20 to move downward a small distance. The second spring 19 provided is compressed by force, so that the bottom of the push plate is closely attached to the top of the casting connector 30. Subsequently, the several second motors 27 provided respectively drive the corresponding rollers 21 to rotate. The several rollers 21 cooperate to drive the casting connector 30 to rotate. When the posture of the casting connector 30 is the same as the posture of the first slot hole 5 formed at the bottom of the material placing cylinder 3, the casting connector 30 provided is pushed into the first slot hole 5 by the second push plate 20.

[0030] Further, two cross plates 28 are welded to the outer peripheral wall of the outer shell 1, and fixing holes 29 are formed in the tops of the two cross plates 28. The cross plates 28 and the fixing holes 29 provided facilitate the fixed installation of the device main body to a specific position.

[0031] Working principle: During use, the casting connectors 30 that have completed the sand falling process are successively dropped into the inner cavity of the material placing cylinder 3. Subsequently, the first electric push rod 9 drives the inner shell 10, the rotating rod 12, and the first push plate 15 to move downward, causing the first push plate to abut against the bottom area of the inclined surface of the inclined surface ring 4. Subsequently, the first motor 25 drives the first gear 26 to rotate. The provided first gear 26 drives the toothed ring 11 to rotate, and the provided toothed ring 11 drives the second gear 14, the rotating rod 12, and the first push plate 15 to rotate. Since the several first push plates 15 are oriented in different directions, the several first push plates 15 can successively push the material placing cylinder 3 to shake when rotating. In addition, since the first push plate 15 abuts against the bottom area of the inclined surface of the inclined surface ring 4, the rotating first push plate 15 performs a large-amplitude and multi-angle vibration operation on the material placing cylinder 3. With the vibration of the material placing cylinder 3, the casting connectors 30 in the inner cavity of the material placing cylinder 3 lie flat on the bottom of the inner cavity of the material placing cylinder 3; it should be noted that in the initial state, the provided second push plate 20 is located outside the material placing cylinder 3. When the inner shell 10 moves downward, the provided second push plate 20 moves downward with the inner shell 10 to the bottom of the material placing cylinder 3. When the rotating rod 12 drives the first push plate 15 to rotate, the provided second push plate 20 will not collide with the material placing cylinder 3; A small amount of sand adheres to the surface of the casting connectors 30 after sand falling. During the above vibration process, the small amount of sand adhering to the surface of the casting connectors 30 shakes off under the action of vibration. Since the central area at the bottom of the inner cavity of the material placing cylinder 3 bulges slightly, the sand after shaking off slides along the inclined surface at the bottom of the inner cavity of the material placing cylinder 3 to the edge of the bottom of the inner cavity of the material placing cylinder 3, and finally the sand further slides into the annular aggregate box 24 through the third slot 23, thereby realizing the cleaning and collection of the sand;

[0032] Then the electric push rod 19 drives the inner shell 10, the rotating rod 12 and the push plate 15 to reset upwards. At this time, the push plate 20 and the slot 22 opened on the side wall of the material placing barrel 3 are located on the same horizontal line. Then the motor 125 drives the gear 126 to rotate, and the gear 126 drives the gear ring 11 to rotate. The gear ring 11 drives the gear 214, the rotating rod 12 and the push plate 20 to rotate. The rotating push plate 20 pushes the casting connector 30 to the center position of the bottom of the inner cavity of the material placing barrel 3, thereby realizing the casting connector 3 0 centering effect; then the electric push rod 27 drives the gasket 8 to move down, and the set gasket 8 moves out of the slot 5. It should be noted that the top plane of the gasket 8 after moving down is on the same horizontal line as the bottom plane of the material placing barrel 3; then the electric push rod 19 drives the push plate 20 to move down a short distance, and the set spring 219 is compressed by force, so that the bottom of the push plate is tightly attached to the top of the casting connector 30; then the set several motors 27 respectively drive the corresponding rollers 21 to rotate, and the several rollers 21 work together to drive the casting connector The casting connecting piece 30 rotates; when the posture of the casting connecting piece 30 is the same as the posture of the slot hole 5 opened at the bottom of the placing barrel 3, the casting connecting piece 30 is pushed into the slot hole 5 by the push plate 20; then the push plate 20 is reset to the outside of the placing barrel 3, and then the electric push rod 9 drives the inner shell 10, the rotating rod 12 and the push plate 15 to move downward, so that the push plate 15 abuts against the top area of ​​the inclined surface of the bevel ring 4, and then the motor drives the push plate 15 to rotate. Since the push plate 15 abuts against the top area of ​​the inclined surface of the bevel ring 4, the rotating The push plate 15 performs a small-amplitude, multi-angle vibration operation on the opposite barrel 3, thereby promoting the casting connector 30 to break free from the slot 15; during the above-mentioned vibration process, the electric push rod 27 is slowly driven by the gasket 8 to move downward, so as to receive the gradually moving downward casting connector 30; after the casting connector 30 falls to the top of the gasket 8, the casting connector 30 is placed in a more accurate posture at this time, which is convenient for the external clamp to transfer the casting connector 30 on the top of the gasket 8 to the cleaning platform for subsequent deburring, burr removal and other related treatments.

[0033] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
