[0002] Container corner fittings are an important part of the container body and are usually made of steel casting or reinforced plastic. Container corner fittings are divided into four types: upper corner fittings, lower corner fittings, front corner fittings and rear corner fittings. They are used to connect and reinforce the corner areas of the container, protecting the container's payload and stabilizing the snap-on container body. Taking the upper corner fittings as an example, they are generally rectangular and hollow inside. There are side holes on the two adjacent sides and a waist-round hole on the top, also called a top hole. After the corner fittings are formed, the outer edge of the top hole needs to be chamfered or rounded, i.e., ground.

[0003] In the traditional container corner fitting hole grinding operation, although the grinding process is operated by mechanical automation, the loading and unloading of materials are all manually operated. Moreover, since the container corner fittings are generally heavy, this not only continuously consumes physical strength and increases labor costs, but also has relatively low efficiency. Therefore, an automatic container corner fitting hole grinding tool is proposed. Utility Model Content

[0019] Secondly, the present invention is described in detail with reference to the schematic diagram.

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Figure 1-Figure 3 The following is a schematic diagram of the entire structure of an automatic hole grinding tool for container corner parts of the utility model. Figure 1-Figure 3 In this embodiment, an automatic hole grinding tool for container corner fittings includes a workbench 100, an extension portion 110 is provided at the front end of the workbench 100, a first transmission belt 200 is provided on the upper part of the extension portion 110 along its length direction and one end of which extends to the edge of the workbench 100, parallel and opposite clamping plates 300 are provided on both sides of the upper part of the workbench 100 and close to the extension portion 110, and cylinders 400 that can drive the two clamping plates 300 to move relative to or back to each other are provided on both sides of the upper part of the workbench 100. A second transmission belt 500 is arranged adjacent to the rear end of the splint 300, an electric push rod 600 is arranged at the upper rear end of the workbench 100, and the output shaft of the electric push rod 600 and the first transmission belt 200 have the same central axis, a rotating drive component 610 is arranged at the outer end of the output shaft of the electric push rod 600, and a clamping strip 620 corresponding to the side hole of the container corner fitting is arranged at the output end of the rotating drive component 610; wherein the length and width of the clamping strip 620 are both smaller than the length and width of the side hole of the container corner fitting.

[0022] Limiting side plates 210 are also arranged in parallel on both sides of the first transmission belt 200 and fixed to the upper end of the extension part 110. During operation, the container corner pieces after preliminary forming processing can be directly sent to the first transmission belt 200 so as to be transmitted to the subsequent hole grinding stage. At the same time, the limiting side plates 210 arranged on both sides can limit and straighten the corner pieces in transmission, so that the corner pieces can smoothly enter the processing station of the workbench 100, which is simple and efficient.

[0023] A positioning end plate 310 is vertically fixed to the rear end of the clamp 300, and the positioning end plates 310 at the rear ends of the clamps 300 on both sides are relatively arranged. The clamping surfaces of the clamps 300 and the positioning end plates 310 are also provided with rubber pads 320. When the corner piece is pushed to the processing station, the clamps 300 on both sides can quickly clamp and position the middle corner piece under the push of the cylinder 400. It can be understood that the positioning end plate 310 can limit the stroke of the corner piece entering the station so that the clamp 300 can clamp more accurately, which is beneficial to the targeted operation of the upper grinding device. At the same time, the rubber pads 320 make the clamps 300 and the positioning end plates 310 clamp the corner pieces more firmly and prevent the outer walls of the corner pieces from being damaged or scratched.

[0024] The rotating driving component 610 is a stepper motor, and the output end of the stepper motor has a rotating shaft 611, and the middle part of the clamping strip 620 is vertically fixed to the rotating shaft 611. In this embodiment, when the first transmission belt 200 transmits the corner piece to the middle position of the two side clamps 300, the clamping strip 620 is in a vertical state at this time, and under the push of the electric push rod 600, the clamping strip 620 is inserted into the side hole of the corner piece, and then the stepping motor drives the clamping strip 620 to rotate to a horizontal state. In this way, the electric push rod 600 can directly pull the corner piece backward through the clamping strip 620 and the side hole, so that the rear end face of the corner piece is in contact with the positioning end plate 310, and then it is clamped and positioned by the clamp 300. At the same time, after the grinding is completed, the corner piece is pulled to the second transmission belt 500 through the same principle, and then rotated and pushed, and then the second transmission belt 500 is started to take the corner piece away. The operation process is simple and efficient, and the automatic loading and unloading operation is effectively realized, and the grinding efficiency is further improved.

[0025] A discharge chute 120 for installing the second transmission belt 500 is also provided on the upper part and inner side of the workbench 100, and the top height of the second transmission belt 500 is lower than the top height of the discharge chute 120. The purpose of this design is that the polished corner pieces can be smoothly dragged onto the second transmission belt 500. At the same time, the polished corner pieces can be directly pushed and unloaded by the second transmission belt 500 without manual operation, which saves time and effort and is highly efficient.

[0026] In summary, in the present embodiment, an automated hole grinding tool for container corner fittings can, during operation, directly send the container corner fittings after preliminary forming processing to the processing station of the workbench 100 by the first transmission belt 200. At this time, the clamping strip 620 is in a vertical state, and the clamping strip 620 is pushed by the electric push rod 600 to penetrate into the side hole of the corner fitting, and then the stepper motor drives the clamping strip 620 to rotate to a horizontal state. In this way, the electric push rod 600 can directly pull the corner fitting backward through the clamping strip 620 and the side hole, so that the rear end face of the corner fitting is in contact with the positioning end plate 310, and then it is clamped and positioned by the clamp plate 300. At the same time, after grinding is completed, the corner fitting is pulled onto the second transmission belt 500 by the same principle, and then rotated and pushed, and then the second transmission belt 500 is started to take the corner fitting away. The operation process is simple and efficient, and the automated loading and unloading operation is effectively realized, and the grinding efficiency is further improved.
