Description

Technical Field

[0001] The utility model belongs to the technical field of fish belly beam production, and particularly relates to a fish belly beam fish belly weld root cleaning device. Background Art

[0002] Fish belly beams are usually made of I-beams as raw materials during the production process. The webs at both ends of the material are cut to form a fish belly shape, and then the webs on both sides of the cut are pressed together. Finally, the pressed seams are welded. When welding the seams, both sides of the web need to be welded. In order to improve the welding quality, after welding one side of the web, the completed weld needs to be root cleaned to remove defects at the root of the weld. After the root cleaning is completed, the other side of the web can be welded. Root cleaning of welds is generally performed using equipment such as carbon arc gouging, pneumatic shovels, electric grinding wheels, and milling power heads. During the root cleaning process, the material is easily moved by force. If the material cannot be stabilized, uneven root cleaning will result, affecting the processing quality. In addition, the processed materials generally have different widths, and the existing root cleaning equipment cannot position materials of different widths and specifications, making it less practical.

[0024] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0025] like Figures 1-8As shown, a fish belly beam and fish belly weld root cleaning device includes an intermediate transmission mechanism 1, an end transmission mechanism 2, and a milling mechanism 3. The intermediate transmission mechanism 1 and the end transmission mechanism 2 are connected to each other and are used to transmit materials. The intermediate transmission mechanism 1 and the end transmission mechanism 2 both include a transmission frame 4 and a material transmission roller. The material transmission roller is arranged on the top of the transmission frame 4, and the material is transmitted on the material transmission roller. The milling mechanism 3 is mounted above the end transmission mechanism 2 and can move along the material transmission direction. The milling mechanism 3 is used to clean the weld root and can adjust its working position according to the direction of the weld during operation. The transmission frame 4 in the intermediate transmission mechanism 1 is provided with multiple adjustable positioning components along the material transmission direction. The adjustable positioning components are used to position the middle of the material during the root cleaning process and are suitable for materials of different widths. The transmission frame 4 in the end transmission mechanism 2 is provided with multiple wing plate restraining components on one side of the top along the material transmission direction. The wing plate restraining components are used to restrain the wing plates at the ends of the material during the root cleaning process.

[0026] During the actual processing process, both ends of the intermediate transmission mechanism 1 can be connected to the end transmission mechanism 2, and then the middle of the material can be positioned by the adjustable positioning component on the intermediate transmission mechanism 1, and the wing plates at both ends of the material can be constrained respectively by the wing plate constraint components on the two end transmission mechanisms 2. At the same time, milling mechanisms 3 are arranged above the two end transmission mechanisms 2, so that the welds at both ends of the material can be cleaned at the same time by the two milling mechanisms 3. During the root cleaning process, there is no need to change the direction of the material or switch the work station, and the work efficiency is higher.

[0027] like Figure 4 、 Figure 5 As shown, the material conveying roller includes a conveying motor 5, a conveying roller 6, a driven roller 7, and a lateral guide wheel 8. The conveying roller 6 and the driven roller 7 are alternately installed on the top of the conveying frame 4 along the material conveying direction. The conveying roller 6 is driven by the conveying motor 5 on the top of the conveying frame 4, and the lateral guide wheels 8 are installed on both sides of the top of the conveying frame 4 between the conveying roller 6 and the driven roller 7. The conveying roller 6 is driven to rotate by the conveying motor 5, and the material is conveyed in cooperation with the driven roller 7. The lateral guide wheel 8 is in rolling contact with the material's wing plate during the conveying process, thereby guiding the material. In addition, as shown in FIG. Figure 1 、 Figure 8 As shown, a guide wheel set 23 is installed at the top end of the transmission frame 4 in the end transmission mechanism 2 away from the middle transmission mechanism 1, which is used to transmit and guide materials when the end transmission mechanism 2 is docked with other processing stations.

[0028] As shown Figure 1-Figure 3As shown, the milling mechanism 3 includes a guide rail 31, a support seat 32, a milling gantry 33, a y-axis linear module 34, a z-axis linear module 35, and a milling power head 36. Guide rails 31 are provided on both sides of the transmission frame 4 along the material transmission direction. Support seats 32 are slidably provided on the two guide rails 31. The crossbeam of the milling gantry 33 is provided above the end transmission mechanism 2. The two legs of the milling gantry 33 are respectively fixed on the two support seats 32. The y-axis linear module 34 is installed on the crossbeam of the milling gantry 33. The z-axis linear module 35 is installed on the y-axis linear module 34. The milling power head 36 is installed on the z-axis linear module 35. A height tracking sensor 37 is installed on the milling power head 36. As shown Figure 2 、 Figure 7 As shown, a rack 21 is fixed on one side opposite to the other of the two guide rails 31 along the length direction of the guide rails 31, a motor is installed on the support seat 32, and a gear 22 meshing with the rack 21 is fixed to the output end of the motor. During the root cleaning process, according to the direction of the weld, the motor drives the gear 22 to rotate, and then drives the support seat 32 to slide along the guide rail 31 under the meshing of the gear 22 and the rack 21. At the same time, the position of the milling power head 36 is adjusted under the drive of the y-axis linear module 34 and the z-axis linear module 35. The milling power head 36 cleans the weld by milling. The height tracking sensor 37 detects the weld excess height during the root cleaning process, and then adjusts the height of the milling power head 36 according to the detection result, so that the weld excess height after root cleaning remains consistent, thereby ensuring the processing quality. In this embodiment, the height tracking sensor adopts a contact displacement sensor.

[0029] The weld of the fish belly beam is in a "Z" shape, and the milling power head 36 operates along the weld. The specific milling trajectory control principle is as follows:

[0030] According to the workpiece drawing and process, points are collected for the "Z" pattern required by the process; the graphic structure of each segment is subdivided, and the trajectory is functionalized into three-axis functions (which may involve plane geometry (plane interpolation) and solid geometry (helical interpolation)) formula calculations, and then arranged in order and stored in the control system as data. Multiple trajectories can be stored; the previous trajectory data is called up with one click or automatically as needed; the control system operates according to the trajectory data.

[0031] like Figure 4 、 Figure 6As shown, the adjustable positioning assembly includes a base plate 9, a positioning support 10, a positioning pad 11, an adjustment support 12, a tightening cylinder 13, and a tightening head 14. The two ends of the base plate 9 are respectively fixed to the top of the transmission frame 4, the positioning support 10 is fixed to one end of the base plate 9, the adjustment support 12 is movably arranged at the other end of the base plate 9, the positioning pad 11 is fixed to the side of the positioning support 10 opposite to the adjustment support 12, and the other end of the base plate 9 is provided with two parallel strip holes 15 along the length direction of the base plate 9. The strip holes 15 are penetrated by adjusting bolts 16 that are slidably connected to the strip holes 15. The adjusting bolts 16 pass upward through the bottom of the adjustment support 12 and are connected to the adjusting nut 17. The tightening cylinder 13 is installed on the adjustment support 12, and the tightening head 14 is fixed to the output end of the tightening cylinder 13 and opposite to the positioning pad 11. When the material is transferred to the root cleaning station, the tightening cylinder 13 drives the tightening head 14 to push against the material flange, so that the flange on the other side of the material contacts the tightening head 14, and then fixes the middle of the material between the tightening head 14 and the positioning pad 11, thereby achieving the positioning of the middle of the material. Before the root cleaning operation, loosen the adjusting bolt 16 and the adjusting nut 17, and move the adjusting support 12 along the strip hole 15 according to the width of the material to adjust the position of the adjusting support 12. Then tighten the adjusting bolt 16 and the adjusting nut 17 to fix the adjusting support 12. Then, it can be used to position materials of different widths and specifications, improving the practicality of the equipment.

[0032] like Figure 1 、 Figure 5 As shown, the wing plate constraint assembly includes a constraint plate 18, an angle motor 19, and a baffle 20. The constraint plate 18 is upright and fixed on one side of the top of the transmission frame 4. The top and bottom of the outer wall of the constraint plate 18 are both installed with angle motors 19. The output shaft of the angle motor 19 is fixed with a baffle 20 located on the inner side of the constraint plate 18. When the material is being transported, the baffle 20 is in an initial state, and its free end is away from the material. When the material is transported to the root cleaning station, the angle motor 19 drives the baffle to rotate, so that the free end of the baffle rotates to the inner side of the material flange, and the free end of the baffle abuts against the inner side of the material flange, and then the flange on one side of the material end is constrained by the baffle. In this way, the positioning of the material by the adjustable positioning assembly can ensure the stability of the material during the root cleaning process, prevent the material from being forced to move, and improve the processing quality.
