Description
Technical Field

In the prior art, the packing operation of multiple parcels is usually completed on a packing table. The existing packing table usually has a frame structure composed of a crossbeam and a longitudinal beam. Two longitudinal beams are arranged at intervals, and multiple crossbeams are arranged between the two longitudinal beams. The two ends of the crossbeam are welded to the two longitudinal beams. Due to the large amount of heat generated during welding, the two ends of the crossbeam are deformed after welding. Therefore, it needs to be corrected after welding. The correction method of the prior art is that a worker holds a hammer and knocks the end of the crossbeam upward from the lower end surface of the crossbeam , so that the end of the beam is flush with the middle of the beam, but during correction, workers cannot control the knocking force well, and may not be able to correct it in one knock. Repeated knocking and adjustment may be required. There may also be a situation where the crossbeam is damaged due to excessive knocking, resulting in high production costs for the package building platform.

[0035] In this embodiment, the frame structure refers to the package building platform in the prior art, such as the attached Figure 8 It is a package building platform in the prior art. The package building platform includes two groups of welding platforms. There is some distance between the two groups of welding platforms. One group of welding platforms includes two longitudinal beams and multiple cross beams. The other group of welding platforms also includes two longitudinal beams and multiple cross beams. The two groups of welding platforms have the same structure and are arranged side by side. The front and rear ends of the two groups of welding platforms are fixed together by connecting beams. Side plates are fixed on the left and right sides of the two groups of welding platforms. The front of the welding platform is horizontal, and the rear is tilted downward.
[0036] When assembling the package platform, take a set of welding platforms as an example. Two longitudinal beams are set at intervals, and multiple cross beams are set between the two longitudinal beams from front to back. The two ends of the cross beam are welded to the two longitudinal beams on both sides. Due to the large amount of heat generated during welding, the two ends of the cross beam will be warped and deformed after welding. Therefore, the two ends of the cross beam need to be corrected after welding.
[0037] The utility model provides an automatic correction device, as shown in the attached Figure 1-7 The utility model can be provided with a control system on the frame 1, the control system is such as a PLC control system, the adjustment cylinder 5, the correction cylinder 6, the lifting cylinder 9, the front and rear drive motors 14, etc. are all connected to the control system and controlled by the control system.
[0038] In the utility model, two positioning platforms 3 can be arranged on the base 10 of the frame 1 according to the spacing between the two sets of welding platforms. One positioning platform 3 corresponds to one adjustment cylinder 5 and one pressing plate 7. The shape of the upper end surface of the positioning platform 3 matches the shape of the welding platform of the package building platform. For the convenience of description, the following figure is used as an example. Figure 1 The orientation is explained here, and other drawings refer to this figure, such as the attached Figure 1 The upper end surface of the front part of the positioning platform 3 is a horizontal plane, and the upper end surface of the rear part of the positioning platform 3 is inclined downward from front to rear to form an inclined surface, which corresponds to the front part of the welding platform being horizontal and the rear part being inclined downward.
[0039] The front support 15 is arranged in front of the fixed axis 11, and the rear support 16 is arranged behind the fixed axis 11. The positioning table 3 can swing forward and backward around the fixed axis 11, and the support plate 4 is arranged on the inner side of the positioning table 3. The base 10 is sequentially provided with the support plate 4, the first positioning table, the first adjustment cylinder, the second positioning table and the second adjustment cylinder from the inside to the outside. When calibrating, it is necessary to calibrate one end of the front beam of the welding table first, and then calibrate one end of the rear beam of the welding table, and then rotate the welding table 180°, and then put the welding table on the positioning table, first calibrate the other end of the front or rear beam of the welding table, and then calibrate the other end of the rear or front beam of the welding table. The specific steps are as follows:
[0040] As attached Figure 6 The beams of the two welding platforms of the package building platform are respectively placed on the first positioning platform and the second positioning platform. The side plate of the package building platform is against the back plate 4. In the initial position, the pressing plate 7 is located above the horizontal plane of the front of the positioning platform 3.
[0041] Start the lifting cylinder 9 and drive the pressure plate 7 downward. The two pressure plates 7 are respectively pressed on the beams of the two welding tables of the package building platform. Start the front and rear drive motors 14 and the correction cylinder 6, so that the correction cylinder 6 moves forward and backward while moving up and down, and hits the end of the beam upward. The upper end of the beam abuts against the pressure plate 7, and the beam is kept horizontal by the pressure plate 7. Most of the lower end of the beam is supported by the positioning platform and cooperates with the pressure plate to keep the beam horizontal. The end of the beam to be corrected above the correction cylinder corresponds to the end of the beam to be corrected. The correction cylinder 6 cooperates with the pressure plate 7 to hit the beam to ensure that the beam abuts against the pressure plate to achieve correction of the end of the beam. The control system controls the correction cylinder 6 and the front and rear drive motors 14 to After the correction cylinder 6 moves a few steps, the correction cylinder 6 is started and extended upward to hit the beam. The telescopic rod of the correction cylinder 6 moves up and down and can hit once or twice. It can be set according to the needs. The distance at which the correction cylinder 6 stops can be set according to the spacing between the beams on a group of welding tables on the construction platform. The front of the welding table is horizontal. After the correction of one end of the beam at the front of the welding table is completed, the correction cylinder 6 and the front and rear drive motors 14 are turned off, the lifting cylinder 9 is started, the pressure plate 7 is raised, and the adjustment cylinder 5 is started. The adjustment cylinder 5 swings the rear part 3 of the positioning table upward, so that the welding table on the inclined surface at the upper end of the positioning table 3 is adjusted to the horizontal, and the front lower end of the positioning table 3 is against the front support 15, as shown in the attached Figure 7 After the adjustment is completed, close the adjustment cylinder 5, then pull out the positioning pin, move the mobile frame 20 backward, move the mobile frame 20 backward, so that the pressure plate 7 is facing the rear of the welding table of the package building table. After the position is appropriate, the positioning pin passes through the pin hole and the positioning hole to fix the mobile frame 20 to the frame 1, and then fix the position of the pressure plate 7.
[0042] Generally speaking, the length of the front and rear of the package building platform are fixed, so the pressing plate only needs to have two positions. The pressing plate 7 corresponds to the front of the positioning platform 3 at the front, and the pressing plate 7 moves to the rear to correspond to the rear of the positioning platform 3. Of course, a plurality of pin holes can also be set on the front and rear guide rails 19 to facilitate further adjustment of the pressing plate 7. The moving frame 20 and the front and rear guide rails 19 can be slidably connected or rollingly connected. In order to facilitate quick positioning, the front and rear inner walls of the front and rear guide rails 19 can also limit the moving frame 20 so that the moving frame 20 moves forward. When the front end of the moving frame 20 abuts against the front inner wall of the front guide rails 19, the pressing plate is located directly above the front of the positioning platform 3, and the moving frame 20 moves backward. When the rear end of the moving frame 20 abuts against the rear inner wall of the front and rear guide rails 19, the pressing plate is located directly above the rear of the positioning platform 3. In order to prevent the moving frame 20 from shaking during use, the moving frame 20 and the front and rear guide rails 19 can be fixed by positioning pins. It can be set according to needs.
[0043] Start the lifting cylinder 9 to drive the pressing plate 7 to descend, and the pressing plate 7 is pressed on the beam at the rear of the welding table. Start the front and rear drive motors 14 to drive the correction cylinder 6 to continue to move forward and backward. Start the correction cylinder 6, and the correction cylinder 6 moves upward to hit the beam to hit the uneven part of the end of the beam. The upper end of the beam end is against the pressing plate 7 and does not move. The correction cylinder 6 makes it horizontal by hitting it. Control the correction cylinder 6 and the front and rear drive motors 14 so that the correction cylinder 6 moves and hits the beam to correct the beam. When one end of the beam at the rear of the welding table is corrected, turn off the correction cylinder 6 and the front and rear drive motors 14, start the lifting cylinder 9, raise the pressing plate 7, remove the package building table, rotate the package building table 180 degrees, and then put the package building table on the positioning table 3. According to the above operating steps, the package building table at the upper end of the rear of the positioning table can be corrected first. In this way, the positioning The platform does not need to rotate, and the pressing plate 7 will not move forward. The pressing plate 7 can be corrected after it is lowered and positioned. The steps are as above. After the correction is completed, the pressing plate 7 rises and the adjusting cylinder 5 is started. The adjusting cylinder 5 swings the front of the positioning platform 3 upward, so that the front of the positioning platform 3 is adjusted to a horizontal plane, the positioning pin is pulled out, and the movable plate 20 is moved so that the pressing plate 7 is located above the front of the positioning platform 3. The steps are as above, the package building platform is positioned and corrected. After the correction is completed, this package building platform is removed, and the next package building platform to be corrected is taken out and the above operation steps are continued for correction. The utility model has a clever structure and is easy to operate. The package building platform is limited by the support plate 4, and the beam is positioned together with the positioning platform 3 and the pressing plate 7. The beam is hit upward by the correction cylinder 6, so that the beam is close to the pressing plate 7 at its upper end, and then the end of the beam is flush with the middle of the beam, and the beam correction operation is completed.
[0044] The utility model adopts the above structure, has the advantages of ingenious structure, time and labor saving, automatic correction, high correction efficiency and the like.
