DETAILED DESCRIPTION

[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] Embodiment 1, as Figure 1 to Figure 3 As shown, this embodiment aims to reduce the labor intensity in the boring process of container corner fittings and improve the processing efficiency. To this end, the boring equipment for container corner fitting processing provided in this embodiment includes a turntable 2 and a corner fitting fixing station 3 arranged on the turntable 2. The turntable 2 is mainly arranged to facilitate the adjustment of the position of the corner fitting fixing station 3, and the corner fitting fixing station 3 is mainly used to fix the container corner fittings and adjust the angle of the container corner fittings. Taking into account that the container corner fittings have holes on the front end face, the right side face and the top face, a total of 5 corner fitting fixing stations 3 are set, which can be divided into a discharge station 6, a boring end face station 7, a boring top face station 8, a boring side face station 9 and a blanking station 10 according to the work content. Among them, the discharge station 6 is used to receive the container corner fittings moved from the manipulator; the boring end face station 7 is used to realize the processing of the front end face surface of the container corner fittings; the boring top face station 8 is used to process the top face surface of the container corner fittings; the boring side face station 9 is used to process the right side face surface of the container corner fittings; and the blanking station 10 is used for the manipulator to unload. 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, then the last processed holes need to restore the top face upward before they can be processed. In this way, there is one more 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 the 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 passes through the lower turntable 22. One end of the drive shaft 23 passing through the lower turntable 22 is connected to a motor reducer. In this way, through the setting of the motor reducer, the upper turntable 21 and the lower turntable 22 can be rotated simultaneously.

[0022] Since the container corner fitting has three faces that need to be bored, the corner fitting fixing station 3, in addition to fixing the container corner fitting, also needs to change the angle of the container corner fitting to ensure that the faces that need to be bored are exposed under the boring tool. To this end, the corner fitting fixing station 3 provided in the present embodiment includes a lower coupling 31 arranged on the lower turntable 22 and a driving cylinder 32 arranged at the end of the lower coupling 31 away from the lower turntable 22. In the present embodiment, for convenience and practicality, the driving cylinder 32 is an electric cylinder, and the power end of the driving cylinder 32 is arranged upward and connected with the upper coupling 33, and a suction cup 34 is arranged at the end of the upper coupling 33 away from the driving cylinder 32. At the same time, a through hole 211 for exposing the suction cup 34 is provided on the upper turntable 21, and a connecting plate 35 is provided 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, and the angle between adjacent connecting plates 35 is 90°. In this way, the four connecting plates 35 are on the four surfaces of front, back, left and right. For the convenience of installation, and considering that the shape of the container corner fitting is also a rectangular parallelepiped, the suction cup 34 is also arranged in a rectangular parallelepiped in the present embodiment.

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

[0024] It should be noted that, since the existing container corner pieces are cast iron or cast aluminum, if they are cast iron, the suction cup 34 is an electromagnetic suction cup 34, and 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, a boring mechanism 12 is provided above the end surface boring station, the top surface boring station, and the side surface boring station. In this embodiment, a fixed frame 11 is provided on the periphery of the turntable 2, and a three-axis moving mechanism 13 is provided on the fixed frame 11. The boring mechanism 12 is provided at the output end of the three-axis moving mechanism 13. The three-axis moving mechanism 13 is a mechanism for realizing X, Y, and Z three-axis movement, which is an existing mature mechanism, and therefore, in this embodiment, it is not described in detail.

[0026] Considering that there may be a small angle deviation when the manipulator places the container corner fitting, a stopper 341 is provided at the corner of the suction cup 34, and a positioning push rod is also provided on the upper turntable 21. The power end of the positioning push rod is provided with a positioning stopper 341, and the positioning stopper 341 is provided at the diagonal end of the stopper 341 relative to the suction cup 34. The cross sections of the stopper 341 and the positioning stopper 341 are both provided at right angles. That is, the stopper 341 and the positioning stopper 341 can both abut against the two surfaces of the container corner fitting. In this way, when the manipulator places the container corner fitting on the suction cup 34, the positioning push rod works to push the container corner fitting to move in the direction of the stopper 341, so as to achieve accurate placement. Then, the suction cup 34 is opened to complete the fixation of the container corner fitting.

[0027] Considering that the motor reducer is at the bottom, and the turntable 2 needs to place at least four container corner pieces, in order to ensure the stability of the turntable 2 when rotating, in this embodiment, a frame is arranged on the periphery of the turntable 2, and the frame 1 is sleeved on the outside of the turntable 2. A placement hole for placing the turntable 2 is arranged on the frame 1, and an annular groove is arranged on the side wall of the placement hole. An annular protrusion matching the annular groove is arranged on the side wall of the upper turntable 21 and the lower turntable 22. In this way, the turntable 2 is supported by the frame during the rotation process, ensuring its rotation stability.

[0028] Through the above-mentioned arrangement, the streamlined and automated boring of container corner fittings is realized, which reduces the labor intensity and improves the work efficiency.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
