Description

Technical Field

[0001] The utility model relates to the technical field of container manufacturing, and particularly relates to a boring device for a folding container. Background Art

[0002] A folding container generally includes a chassis and end walls. The chassis and the end walls are connected by hinges. The hinges include fixed hinges welded at the end corners of the chassis and movable hinges welded on the end walls. The fixed hinges and the movable hinges are rotatably connected together by hinge pins. When assembling the folding container, in order to improve the accuracy of the hinges, boring equipment is usually required to process the pin holes on the fixed hinges and the movable hinges to improve the assembly accuracy of the chassis and the end walls. The existing boring equipment places the folding container on a positioning bench. After adjusting the position of the boring machine, the pin holes on the fixed hinges and the movable hinges of the folding container are processed. It can only be applicable to folding containers with fixed sizes, that is, it can only process standard 40-foot or 20-foot folding containers, and cannot be applicable to both 40-foot and 20-foot folding containers at the same time. The versatility of the equipment is poor. Moreover, after positioning the folding container by using the positioning bench, there are certain errors in adjusting the moving distance of the boring machine, resulting in low boring accuracy.

[0031] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0032] like Figure 1-11As shown in the figure, a boring device for a folding container of the utility model comprises a frame 10 and two end seats 200. In the figure, the X direction is the length direction of the frame 10, the Y direction is the width direction of the frame 10, and the Z direction is the height direction of the frame 10. The two end seats 200 are respectively fixed to the two ends of the length direction of the frame 10. The end seats 200 are provided with longitudinal positioning members 22 and a first driving cylinder 21. The telescopic rod 211 of the first driving cylinder 21 is arranged along the front length of the frame 10. The telescopic rods of the first driving cylinders 21 on the two end seats 200 are all toward the middle of the length direction of the frame 10 and can move in the length direction of the frame 10; the boring equipment includes four boring machines 50, wherein a boring machine 50 is respectively arranged on both sides of each end seat 200, and the spindle 51 of the boring machine 50 extends along the width direction of the frame 10, and the boring machines 50 located on both sides of the same end seat 200 are arranged opposite to each other, and their spindles 51 are coaxially arranged. A double-headed hydraulic cylinder 60 is provided on one side of the middle part of the length direction of the frame 10, and the double-headed hydraulic cylinder 60 is fixedly connected to the frame 10 in a detachable manner. The two telescopic rods of the double-headed hydraulic cylinder 60 extend along the length direction of the frame 10. The double-headed hydraulic cylinder 60 can be specifically fixed at the middle position of the length direction of the frame 10. For example, a mounting plate 13 can be fixed on the frame 10, and a key groove 14 extending along the width direction of the frame 10 is provided on the mounting plate 13. The key groove 14 is in the middle position of the length direction of the frame 10, and a convex structure matching the key groove 14 is provided at the bottom of the cylinder body of the double-headed hydraulic cylinder 60. When the double-headed hydraulic cylinder 60 is placed on the mounting plate 13, the convex structure at the bottom of the cylinder body of the double-headed hydraulic cylinder 60 is embedded in the key groove 14, so that the cylinder body of the double-headed hydraulic cylinder 60 is fixed to the frame 10. Of course, the cylinder body of the double-headed hydraulic cylinder 60 can also be further fixed to the frame 10 by bolts or other fixings.

[0033] The boring device of the folding container of the utility model can perform boring processing on 40-foot folding containers and 20-foot folding containers; see Figure 1 , 4 As shown in FIG. 9 , when boring a 40-foot foldable container 80, the 40-foot foldable container 80 is placed on the frame 10 and located between the two end seats 200, as shown in FIG. Figure 2 , 3As shown, first start the first drive cylinder 21 on the right end seat 200 in the figure, and the telescopic rod 211 of the first drive cylinder 21 moves along the X direction to push the right end of the 40-foot folding container 80, so that the 40-foot folding container 80 moves along the X direction until the left end of the 40-foot folding container 80 abuts against the longitudinal positioning support 22 on the left end seat 200. At this time, start the two boring machines 50 on both sides of the left end seat 200. The two boring machines 50 simultaneously perform boring processing on the left sides of the 40-foot folding container 80. After completion, start the first drive cylinder 21 on the left end seat 20 to push the 40-foot folding container 80 to move along the X direction until the right end of the 40-foot folding container 80 abuts against the longitudinal positioning support on the right end seat 200. At this time, use the two boring machines 50 on both sides of the right end seat 200 to simultaneously perform boring processing on the right sides of the 40-foot folding container 80. See FIG. Fig.10 As shown, when boring holes in a 20-foot folding container 90, the double-headed hydraulic cylinder 60 is fixed to the middle of the frame 10, and two 20-foot folding containers 90 are placed on the frame so that the double-headed hydraulic cylinder 60 is located between the two 20-foot folding containers 90. The double-headed hydraulic cylinder 60 is started, and the two piston rods 61 of the double-headed hydraulic cylinder 60 respectively push the two 20-foot folding containers 90 toward the two end seats 200, so that the two sides of the two 20-foot folding containers 90 are respectively pressed against the longitudinal positioning support members 22 on the two end seats 200, and the four boring machines 50 are started at the same time. The ends of the two 20-foot folding containers 90 away from the double-headed hydraulic cylinder 60 are bored respectively. Then, the two 20-foot folding containers 90 are moved horizontally in the X direction for a distance (the distance is roughly the length of a 20-foot folding container), so that the 20-foot folding container 90 on the left is moved out of the rack 10, and a 20-foot folding container 90 is placed in the vacant position on the right side of the rack 10, and the double-headed hydraulic cylinder 60 is started. The above-mentioned action is repeated to bore the two 20-foot folding containers 90 on the rack 10, thereby sequentially boring the ends of multiple 20-foot folding containers 90.

[0034] The boring device for a folding container of the utility model can be applicable to the boring processing technology of folding containers of two sizes, thereby reducing the equipment cost of folding container production. The position of the main shaft of the boring machine is positioned by a fixed distance between a longitudinal positioning support and the boring machine in the length direction of the frame, and there is no need to move the boring machine along the length direction of the frame, thereby improving the boring accuracy of the folding container and ensuring that the end wall of the folding container can be flexibly rotated relative to the base frame.

[0035] In a preferred embodiment, the utility model is further provided with a transverse positioning member 23 on the end seat 200, and a second driving cylinder 24 is provided on the end seat 200. The second driving cylinder 24 and the transverse positioning member 23 are respectively located on both sides of the frame 10, and the telescopic rod 241 of the second driving cylinder 24 is arranged toward the width direction of the frame 10 and can move in the width direction of the frame 10. After the folding container is placed on the frame 10, the second driving cylinder 24 can be started, and the telescopic rod 241 of the second driving cylinder 24 is used to push the folding container along the width direction of the frame 10, and the transverse positioning member 23 and the telescopic rod 241 of the second driving cylinder 24 are used to clamp the folding container in the width direction of the frame 10. In other embodiments, the second driving cylinder 24 and the transverse positioning member 23 can also be installed on the frame 10, so that the two are respectively located on both sides of the frame 10 and arranged opposite to each other. The end seat 200 includes two positioning seats 20 respectively located on both sides of the frame 10, each positioning seat 20 is provided with a longitudinal positioning support 22 and a first driving cylinder 21, the transverse positioning angle piece on the end seat 200 is fixed on one of the positioning seats 20 of the end seat 200, and the second driving cylinder 24 on the end seat 200 is installed on the other positioning seat 20 of the end seat 200.

[0036] A clamping mechanism is provided on each positioning seat 20, and the clamping mechanism includes a rotating arm 31 and a third driving cylinder 32. The middle part of the rotating arm 31 is hinged on the positioning seat 20, so that the rotating arm 31 constitutes a lever structure, one end of the rotating arm 31 forms a clamping part, and the other end is hinged on the telescopic rod of the third driving cylinder 32. The cylinder body of the third driving cylinder 32 is hinged on the positioning seat 20. After the folding container is clamped in the X and Y directions by using the first driving cylinder 21 and the longitudinal positioning support 22, and the second driving cylinder 24 and the transverse positioning support 23, respectively, the third driving cylinder 32 is started to drive the rotating arm 31 to swing, so that the clamping part of the rotating arm 31 swings downward and is clamped on the top of the folding container, thereby cooperating with the frame 10 to clamp the folding container in the Z direction, avoiding the shaking of the folding container during boring, and further improving the accuracy of boring.

[0037] In order to fully clamp the folding container in the Y direction, especially when boring two 20-foot folding containers, to prevent the 20-foot folding containers from being displaced in the Y direction, the utility model arranges two intermediate drive cylinders 11 in the middle of the length direction of the frame 10, and the two intermediate drive cylinders 11 are staggered a certain distance in the length direction of the frame 10. The intermediate drive cylinder 11 is installed on one side of the width direction of the frame 10, and its telescopic rod 111 faces the middle of the width direction of the frame 10 and can move in the width direction of the frame 10. When clamping the folding container, the intermediate drive cylinder 11 can be started to move the folding container toward the direction close to the lateral positioning position 23. Two intermediate positioning members 12 are arranged in the middle of the length direction of the frame 10, and the two intermediate positioning members 12 are arranged opposite to the telescopic rods 111 of the two intermediate driving cylinders 11 respectively. When two 20-foot folding containers are placed on the frame 10, the telescopic rods 111 of the two intermediate driving cylinders 11 move toward the two intermediate positioning members 12, and the opposite intermediate positioning members 12 and the telescopic rods 111 of the intermediate driving cylinders 11 clamp the 20-foot folding containers, thereby clamping the two 20-foot folding containers in the Y direction at the middle position of the frame 10.

[0038] In another preferred embodiment, two lifting mechanisms 40 arranged along the length direction of the frame 10 are provided on the frame 10, and the two lifting mechanisms 40 are respectively located at positions on the frame 10 for placing two 20-foot folding containers. When processing a 40-foot folding container, the two lifting mechanisms 40 are raised, and the 40-foot folding container is received by the two lifting mechanisms 40, and then the two lifting mechanisms 40 are simultaneously lowered to place the 40-foot folding container on the frame 10; when processing a 20-foot folding container, the two lifting mechanisms 40 are raised and receive a 20-foot folding container respectively, and then the two lifting mechanisms 40 are lowered to place the two 20-foot folding containers on the frame 10, so that the two 20-foot folding containers are respectively located on both sides of the double-head hydraulic cylinder 60. A lifting platform 42 is provided on the top of the lifting mechanism 40, and the lifting platform 42 is used to support the folding container. Driven by the lifting mechanism 40, the lifting platform 42 can move up and down between a first position lower than the frame 10 and a second position higher than the frame 10. A conveying mechanism 41 extending along the length direction of the frame 10 is provided on the lifting platform 42. The conveying mechanism is specifically a chain conveying mechanism. After the folding container is driven by the conveying mechanism 41 to move to a predetermined position along the length direction of the frame 10, the lifting mechanism 40 descends, so that the two sides of the folding container are supported by the support beams on both sides of the frame 10, so that the folding container is transferred from the lifting platform 42 to the frame 10.

[0039] In order to prevent the folding container from deviating when it moves along the lifting platform 42 along the length direction of the frame 10, a row of guide components are respectively arranged on both sides of the lifting platform 42, and the guide components include a fixed seat 43 fixed on the lifting platform 42, and a guide wheel 44 pivotally connected to the fixed seat 43, and the rotation axis of the guide wheel 44 is consistent with the height direction of the frame 10. When the folding container is driven by the conveying mechanism 41 to move on the lifting platform 42, the two rows of guide wheels 44 are limited to both sides of the folding container. When the folding container has a small deviation, the guide wheels 44 contact the side of the folding container to guide the moving direction of the folding container, and the guide wheels 44 roll and rub against the side of the folding container to prevent the folding container from being unable to be driven by the conveying mechanism 41 due to excessive resistance.

[0040] In the utility model, a fixed seat 15 is fixed on both sides of the end seat 200 on the frame 10, and a linear guide pair 16 extending along the width direction of the frame 10 is arranged on the fixed seat 15. Two boring machines 50 located on both sides of the end seat 200 are slidably installed on the linear guide pairs 16 on the two fixed seats 15, so that the boring machine 50 can move along the width direction of the frame 10. When the folding container is transferred from the previous workstation to the frame 10, the boring machine 50 is located at a position away from the frame 10 in the Y direction to prevent the folding container from colliding with the main shaft 51 of the boring machine 50. When the folding container is positioned, the boring machine 50 can be moved along the Y direction toward the frame 10 to perform boring processing on the folding container.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein, and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
