Description

Technical Field

[0001] This invention belongs to the field of container corner fitting processing equipment, and particularly relates to a boring device for processing container corner fittings. Background Technology

[0002] Container corner fittings, also known as container corners or lifting corners, are, as the name suggests, fasteners installed at the eight corners of a container. They play a crucial role in the lifting, handling, securing, stacking, and bolting of containers.

[0003] The existing manufacturing process for container corner fittings mainly includes the following steps: smelting: adding steelmaking materials into a furnace to melt into molten steel; casting: pouring the molten steel into a special mold for producing container corner fittings; machining: cutting and boring the cast billet, removing risers, enlarging the hole diameter, improving precision, and forming the shape of the container corner fitting; heat treatment: performing carburizing + quenching + tempering heat treatment on the machined container corner fittings; shot blasting: performing shot blasting on the heat-treated container corner fittings.

[0004] In existing boring processes, horizontal boring machines are mainly used to bore container corner fittings. Although this method can achieve the purpose of boring, container corner fittings have holes on three sides, and only one side can be processed at a time. If the other sides are to be processed, the container corner fitting needs to be removed and then re-fixed. This is not only inefficient, but also because container corner fittings are castings and generally weigh around 11 to 12.5 kg. Therefore, changing the boring surface is not only labor-intensive but also inefficient. Summary of the Invention

[0005] This invention addresses the technical problems existing in the boring of container corner fittings by proposing a boring device for processing container corner fittings that is reasonably designed, simple in structure, easy to operate, and capable of automatically completing the boring of three sides of container corner fittings.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention provides a boring device for processing container corner fittings, including a turntable and a corner fitting fixing station disposed on the turntable. The turntable includes an upper turntable and a lower turntable, which are connected by a drive shaft. The drive shaft passes through the lower turntable, and a motor reducer is connected to one end of the drive shaft passing through the lower turntable. The corner fitting fixing station includes a lower shaft coupling disposed on the lower turntable and a drive cylinder disposed at the end of the lower shaft coupling away from the lower turntable. The power end of the drive cylinder is disposed upward and connected to the upper shaft coupling. A suction cup is disposed at the end of the upper shaft coupling away from the drive cylinder. A through hole for exposing the suction cup is provided on the upper turntable, and a connecting plate is disposed on the side wall of the suction cup. The connecting plates are evenly distributed on the side wall of the suction cup, with an included angle of 90° between adjacent connecting plates. A flip shaft is provided at the end of the connecting plate away from the suction cup. A flip seat for placing the flip shaft is provided on the side wall of the through hole. A flip groove is provided on the flip seat, and the flip shaft is placed in the flip groove. The upper turntable is also provided with an electromagnetic push rod. The power end of the electromagnetic push rod is telescopically located above the flip shaft. The corner piece fixing station includes a feeding station, a boring end face station, a boring top face station, a boring side face station, and a blanking station. The feeding station, boring end face station, boring top face station, boring side face station, and blanking station are evenly arranged along the rotation direction of the turntable. Among them, a boring mechanism is provided above the boring end face station, boring top face station, and boring side face station.

[0007] Preferably, the suction cup is arranged in a cuboid shape.

[0008] Preferably, the suction cup is provided with a corner stop, and the upper turntable is also provided with a positioning push rod. The power end of the positioning push rod is provided with a positioning corner stop. The positioning corner stop is located at the diagonal end of the corner stop relative to the suction cup. The cross-sections of the corner stop and the positioning corner stop are both right angles.

[0009] Preferably, a frame is provided around the turntable, the frame is fitted onto the outside of the turntable, the frame is provided with a placement hole for placing the turntable, the side wall of the placement hole is provided with an annular groove, and the side walls of the upper and lower turntables are provided with annular protrusions that cooperate with the annular groove.

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figures 1-3 As shown, this embodiment aims to reduce the labor intensity and improve processing efficiency of container corner fittings during the boring process. To this end, the boring equipment for processing container corner fittings provided in this embodiment includes a turntable 2 and a corner fitting fixing station 3 set on the turntable 2. The turntable 2 is mainly for facilitating the adjustment of the position of the corner fitting fixing station 3, which is mainly used to fix the container corner fittings and adjust their angles. Considering that the container corner fittings have holes on the front, right, and top surfaces, five corner fitting fixing stations 3 are set up. These stations can be divided into four sections according to their functions: feeding station 6, end face boring station 7, top face boring station 8, side face boring station 9, and unloading station 10. Feeding station 6 is used to receive the container corner fittings moved from the robotic arm; end face boring station 7 is used to process the front face holes of the container corner fittings; top face boring station 8 is used to process the top face holes of the container corner fittings; side face boring station 9 is used to process the right face holes of the container corner fittings; and unloading station 10 is used for unloading by the robotic arm. In this embodiment, the main purpose of processing the front face first, then the top face, and finally the right face is to reduce control. If the top face is processed first, and then the other holes are processed, then the last hole to be processed needs to be restored to the top face first, which adds an extra step. Processing the front face first, then the top face, and finally the right face, or processing the right face first, then the top face, and finally the front face, can reduce one step and improve efficiency.

[0021] In order to cooperate with the use of corner piece fixing station 3, in this embodiment, the turntable 2 includes an upper turntable 21 and a lower turntable 22. The upper turntable 21 and the lower turntable 22 are connected by a drive shaft 23. The drive shaft 23 is set through the lower turntable 22. One end of the drive shaft 23 that passes through the lower turntable 22 is connected to a motor reducer. In this way, by setting the motor reducer, the upper turntable 21 and the lower turntable 22 can be rotated at the same time.

[0022] Since the container corner fittings have three sides that need to be bored, the corner fitting fixing station 3, in addition to fixing the container corner fittings, also needs to change the angle of the container corner fittings to ensure that the side that needs to be bored is exposed under the boring tool. Therefore, the corner fitting fixing station 3 provided in this embodiment includes a lower shaft coupling 31 set on the lower turntable 22 and a drive cylinder 32 set at the end of the lower shaft coupling 31 away from the lower turntable 22. In this embodiment, for ease of use, the drive cylinder 32 is an electric cylinder. The power end of the drive cylinder 32 is set upward and connected to an upper shaft coupling 33. A suction cup 34 is set at the end of the upper shaft coupling 33 away from the drive cylinder 32. At the same time, a through hole 211 for exposing the suction cup 34 is provided on the upper turntable 21. A connecting plate 35 is set on the side wall of the suction cup 34. The connecting plates 35 are evenly distributed on the side wall of the suction cup 34. The included angle between adjacent connecting plates 35 is 90°. In this way, the four connecting plates 35 are located on the front, back, left and right sides. For ease of installation, and considering that the shape of the container corner fitting is also cuboid, the suction cup 34 is also set in a cuboid shape in this embodiment.

[0023] A rotating shaft 36 is provided at the end of the connecting plate 35 away from the suction cup 34. A rotating seat 212 for placing the rotating shaft 36 is provided on the side wall of the through hole 211. A rotating groove 213 is provided on the rotating seat 212, and the rotating shaft 36 is placed in the rotating groove 213. An electromagnetic push rod 4 is also provided on the upper turntable 21. The power end of the electromagnetic push rod 4 is telescopically located above the rotating shaft 36. In this way, the suction cup 34 will rotate around the rotating shaft 36 under the action of the drive cylinder 32 when the power end of the electromagnetic push rod 4 presses the rotating shaft 36 in a certain direction. Thus, through the cooperation of the upper shaft coupling 33, the drive cylinder 32 and the lower shaft coupling 31, the suction cup 34 can be rotated 90 degrees around the rotating shaft 36, so that the surface of the required boring hole can be included on it.

[0024] It should be noted that, since existing container corner fittings are made of cast iron or cast aluminum, if they are cast iron, the suction cup 34 is an electromagnetic suction cup 34; if they are cast aluminum, it is a negative pressure suction cup. In this embodiment, it is an electromagnetic suction cup 34.

[0025] Since boring is required, boring mechanisms 12 are provided above the boring end face station, boring top face station, and boring side face station. In this embodiment, a fixed frame 11 is provided around the turntable 2, and a three-axis moving mechanism 13 is provided on the fixed frame 11. The boring mechanism 12 is located at the output end of the three-axis moving mechanism 13. The three-axis moving mechanism 13 is a mechanism that realizes X, Y, and Z axis movement. It is an existing mature mechanism, so it will not be described in detail in this embodiment.

[0026] Considering the potential for slight angular deviations when the robotic arm places container corner pieces, a corner stop 341 is provided at the corner of the suction cup 34. A positioning push rod is also provided on the upper turntable 21. The power end of the positioning push rod is equipped with the positioning corner stop 341, which is located diagonally opposite the corner stop 34 to the suction cup 34. Both the corner stop 341 and the positioning corner stop 341 have right-angled cross-sections. That is, both the corner stop 341 and the positioning corner stop 341 can abut against two sides of the container corner piece. Thus, when the robotic arm places the container corner piece onto the suction cup 34, the positioning push rod operates, pushing the container corner piece towards the corner stop 341, thereby achieving accurate placement. Then, the suction cup 34 opens, completing the fixation of the container corner piece.

[0027] Considering that the motor reducer is located at the bottom, and the turntable 2 needs to accommodate at least four container corner pieces, to ensure the stability of the turntable 2 during rotation, in this embodiment, a frame is provided around the turntable 2. The frame 1 is fitted onto the outside of the turntable 2, and a placement hole for placing the turntable 2 is provided on the frame 1. An annular groove is provided on the side wall of the placement hole, and annular protrusions that cooperate with the annular groove are provided on the side walls of both the upper turntable 21 and the lower turntable 22. In this way, the turntable 2 is supported by the frame during rotation, ensuring its rotational stability.

[0028] The above setup enables automated and streamlined boring of container corner fittings, reducing labor intensity and improving work efficiency.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
