Description

Technical Field

[0001] The utility model belongs to the technical field of fish belly beam production, and particularly relates to fish belly beam weld excess height milling equipment. Background Art

[0002] Fishbelly beams are typically made from I-beams. The webs are cut at both ends of the material to create a fishbelly shape. The webs on either side of the cut are then pressed together, and the welded seam is welded. To ensure weld quality, the weld reinforcement must be controlled within a certain range to avoid excessive weld reinforcement, which can lead to stress concentration and reduced joint performance.

[0003] Milling equipment is typically used to control weld reinforcement by milling away excess weld reinforcement. Since joint welding is performed on both sides of the web, the weld seams on both sides also need to be milled after welding. Double-sided milling requires turning the material, which is difficult due to its heavy weight. Furthermore, the material must be re-fixed before and after turning to prevent it from shifting during milling, which can result in a milled result that does not meet the required reinforcement.

[0022] 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.

[0023] like Figure 1-Figure 5As shown, a fish belly beam weld excess height milling equipment includes a milling base 1, a clamping mechanism, a lifting and transmission component, a milling mechanism, and a flipping mechanism. Two milling bases 1 are provided and the two milling bases 1 are arranged opposite to each other. A plurality of clamping mechanisms are sequentially provided on the milling base 1 along the material transmission direction. The clamping mechanism is provided with a lifting and transmission component. The milling mechanism is provided on the milling base 1 on one side of the clamping mechanism. The milling mechanism can move along the material transmission direction. The flipping mechanism is provided between the two milling bases 1. The flipping mechanism is provided with 25 conveying rollers that cooperate with the lifting and transmission component to transmit the raw materials.

[0024] When the raw material is transported to the milling station through the lifting transmission assembly and the conveying roller 25, the clamping mechanism clamps both ends of the raw material, and then fixes the raw material through the clamping mechanism, and then the milling mechanism starts to mill the weld excess height on the front of the raw material. During milling, the milling mechanism moves along the material transmission direction according to the direction of the weld and adjusts the milling position; after the weld excess height on the front of the raw material is milled, the clamping mechanism releases the raw material, and then flips the raw material 180° through the flipping mechanism. After flipping, the clamping mechanism clamps and fixes the raw material again, and then the milling mechanism starts to mill the weld excess height on the back of the raw material; after the weld excess height on the back of the raw material is milled, the clamping mechanism releases the raw material, and then rotates the raw material 180° through the flipping mechanism, and then transports the raw material to the subsequent processing station through the lifting transmission assembly and the conveying roller 25.

[0025] like Figure 1 、 Figure 2 As shown, the clamping mechanism includes a clamping platform 2, a top plate 3, a first pull rod cylinder 4, a fixed hook 5, a movable hook 6, and a second pull rod cylinder 7. The fixed hook 5 is vertically fixed to one end of the top of the clamping platform 2, the movable hook 6 is vertically arranged at the other end of the clamping platform 2 and is opposite to the fixed hook 5, the middle part of the movable hook 6 is rotatably connected to the side wall of the end of the clamping platform 2 through a rotating shaft, the second pull rod cylinder 7 is horizontally installed at the bottom of the clamping platform 2, the lower end of the movable hook 6 is hinged to the output end of the second pull rod cylinder 7, the first pull rod cylinder 4 is vertically installed at the bottom of the clamping platform 2, the top plate 3 is arranged between the fixed hook 5 and the movable hook 6 and is fixed to the output end of the first pull rod cylinder 4. When the raw material is transferred to the milling station, the first pull rod cylinder 4 drives the top plate 3 to rise, and then supports the end of the raw material through the top plate 3. The second pull rod cylinder 7 drives the movable hook 6 to rotate, so that the upper end of the movable hook 6 is close to the fixed hook 5, and then the movable hook 6 and the fixed hook 5 are clamped on the flanges on both sides of the raw material to achieve clamping of the raw material.

[0026] like Figure 2As shown, the lifting and conveying mechanism includes an electric lift 8, a lifting seat 9, a transmission roller 10, and a transmission motor 11. The electric lift 8 is mounted on one side of the clamping platform 2, and the lifting seat 9 is fixed to the output end of the electric lift 8. The transmission roller 10 and the transmission motor 11 are mounted on the lifting seat 9, and one end of the transmission roller 10 is connected to the output end of the transmission motor 11. The electric lift 8 drives the lifting seat 9 to rise, so that the transmission roller 10 supports the raw material. The transmission motor 11 then drives the transmission roller 10 to rotate, thereby transmitting the raw material. The electric lift 8 drives the lifting seat 9 to descend, so that the transmission roller 10 is separated from the raw material, and transmission stops.

[0027] like Figure 1 、 Figure 3 As shown, the milling mechanism includes an x-axis linear module 12, a y-axis linear module 13, a z-axis linear module 14, a milling column 15, and a milling power head 16. The x-axis linear module 12 is installed on the milling base 1 along the material transmission direction, the milling column 15 is installed on the x-axis linear module 12, the y-axis linear module 13 is installed on the top of the milling column 15, the z-axis linear module 14 is installed on the y-axis linear module 13, the milling power head 16 is installed on the z-axis linear module 14, and the milling power head 16 is installed with a height tracking sensor 31. Driven by the x-axis linear module 12, the y-axis linear module 13, and the z-axis linear module 14, the milling power head 16 can be moved forward and backward, left and right, and up and down, thereby adjusting the position of the milling power head 16 so that the milling power head 16 can perform milling operations on the raw material according to the direction of the weld. The height tracking sensor 37 can detect the weld residual height during the milling process, and then adjust the height of the milling power head 16 according to the detection result, so that the weld residual height after milling remains consistent, thereby ensuring the processing quality. In this embodiment, the height tracking sensor adopts a non-contact displacement sensor. During the milling process, the raw material is clamped and fixed by a clamping mechanism, thereby preventing the raw material from being forced to move and improving the processing quality. The welds at both ends of the raw material can be milled at the same time by two milling mechanisms. There is no need to change the direction of the raw material or switch the working station during the milling process, which is conducive to improving work efficiency.

[0028] The weld of the fish belly beam is in a "Z" shape, and the milling power head 16 operates along the weld. The specific milling trajectory control principle is as follows:

[0029] 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.

[0030] like Figure 1、 Figure 4 、 Figure 5 As shown, the flip mechanism includes a flip chassis 17, a conveying frame 18, and a flip assembly. The flip assembly is arranged at both ends of the flip chassis 17. The conveying frame 18 is fixed on the flip chassis 17 between the two flip assemblies, and the conveying roller is arranged on the conveying frame 18. Specifically, the flip assembly includes a worm gear lift 19, a flip seat 20, a support roller 21, a flip ring 22, a flip motor 28, and a chain 29. The worm gear lift 19 is installed at the end of the flip chassis 17. The flip seat 20 is fixed to the output end of the worm gear lift 19. The flip seat 20 is a groove-shaped structure. Support rollers 21 are installed at both ends of the flip seat 20. The flip ring 22 is rollingly supported on the two support rollers 21. The flip motor 28 is installed on the side wall of the flip seat 20. A chain 29 is sleeved on the outer peripheral wall of the flip ring 22. A gear meshing with the chain 29 is installed on the output end of the flip motor 28. The flip ring 22 is provided with a gear meshing with the chain 29. The raw material is adapted to the bayonet 23 in shape, and a guide telescopic rod 30 is installed on the flip base 17 below the flip seat 20. The bottom of the flip seat 16 is fixedly connected to the top of the guide telescopic rod 30, so that the raw material passes through the bayonet 23. Then, under the rolling support of the support roller 21, the flip motor 28 drives the flip ring 22 to rotate around its own central axis through the gear and chain 29, thereby driving the raw material to flip; the conveying roller includes a conveying motor 24, a conveying roller 25, a driven roller 26, and a lateral guide wheel 27. The conveying roller 25 and the driven roller 26 are alternately installed on the conveying frame 18 along the material transmission direction, and the conveying roller 25 is driven by the conveying motor 24 on the conveying frame 18. The conveying roller 25 supports the raw material, and the conveying motor 24 drives the conveying roller 25 to rotate and thus transport the raw material. During the raw material transmission process, the raw material flange is in rolling contact with the lateral guide wheel 27, and then the lateral guide wheel 27 is used to laterally limit and guide the raw material to prevent the raw material from shifting during the transmission process. At the same time, the conveying roller 25 and the driven roller 26 are alternately arranged to realize the master-slave alternating transmission of the raw material, making the raw material transmission more stable.

[0031] The working principle of the present invention is as follows: when the weld on the front of the raw material is milled, the transmission motor 11 drives the transmission roller 10 and cooperates with the conveying motor 24 to drive the conveying roller 25 to transmit the raw material. During the transmission process, the raw material passes through the bayonet 23 on the flip ring 22. When the raw material is transmitted to the milling station, the clamping mechanism clamps the raw material, and the electric lift 8 drives the lifting seat 9 to descend, so that the transmission roller 10 is separated from the raw material, the transmission motor 11 and the conveying motor 24 stop working, and then the milling mechanism starts to operate; after the front of the raw material is milled, the clamping mechanism releases the raw material, and then the worm gear lift 19 drives the flip seat 20 to rise, and the guide telescopic rod 30 is used to guide the movement of the flip seat 20, and then the raw material is lifted to the clamping mechanism and the conveying station. Above the roller, there is enough space for the raw material to turn over. Then, under the rolling support of the support roller 21, the turning motor 28 drives the turning ring 22 to rotate around its own central axis through the gear and chain 29, and then turns the raw material 180°. After turning over, the worm gear elevator 19 drives the turning seat 20 to descend, and the clamping mechanism clamps and fixes the raw material again, and then the milling mechanism starts to mill the back of the raw material; after the milling of the back of the raw material is completed, the clamping mechanism releases the raw material, and the turning mechanism repeats the above turning process, so that the raw material rotates 180° and places the raw material on the conveyor roller, and then the electric elevator 8 drives the lifting seat 9 to rise, so that the transmission roller 10 supports the raw material, and finally the raw material is transported to the subsequent processing station through the cooperation of the lifting transmission component and the conveyor roller.
