Description

Technical Field

[0001] The invention belongs to the technical field of plate welding, and in particular relates to integrated plate automatic cutting and welding equipment. Background Art

[0002] With the rapid development of modern industry, industrial design is becoming more and more perfect, advanced and intelligent, and the supervision of environmental pollution and energy efficiency is becoming more and more stringent. Taking passenger and freight transportation as an example, the existing small discrete modes are gradually changing to large public transportation modes. This puts high demands on the manufacturing of large-scale transportation vehicles, especially the outer covering parts of the carriages. Due to the restrictions on the size supply of raw materials from steel mills and transportation, it is difficult to directly purchase plates that meet the width requirements.

[0003] The existing processing method mostly uses steel coils supplied in rolls, which are unrolled, leveled and straightened, and then cut into the required format. This method is very convenient to use, but it has requirements on the width of the incoming steel coils. If the width exceeds the conventional width supplied by the steel mill, this method is not applicable.

[0004] Another commonly used method is the form of multi-plate welding, that is, multiple steel plates commonly supplied on the market are spliced ​​together, the edges to be welded are first processed, and then sent to the welding equipment, and the splicing of each steel plate is fixed by spot welding in turn, and then continuous welding is performed using filler wire. Due to the limitation of the processing technology, the weld edges are pre-processed and then spliced. Due to the changes in the positioning reference and tool reference, it is difficult to ensure the consistency of the splicing gap. Only filler wire can be used to fill the splicing gap, and the weld needs to be ground and polished later to remove the weld bulge caused by uneven gaps. Moreover, the heat input of filler wire welding is large, the heat-affected zone is wide, and the plate is prone to deformation after welding. Therefore, the plate needs to be leveled and straightened, and then cut and trimmed. The process is relatively complicated and the efficiency is low. Summary of the invention

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0045] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0046] like Figure 1 As shown, an embodiment of the present invention provides an integrated plate automatic cutting and welding device, including a feeding device 1, an input positioning device 2, a cutting and welding auxiliary device 3, a roller conveyor device 5 with a liftable anvil, a cutting and welding integrated device 4 for cutting and splicing plates, and a traction device 6 for driving the plates to move; the feeding device 1, the input positioning device 2, the cutting and welding auxiliary device 3 and the roller conveyor device 5 are arranged in sequence along the moving direction of the plates; the cutting and welding integrated device 4 includes a working end and a driving unit for driving the working end to move above the cutting and welding auxiliary device and the roller conveyor device. The integrated plate automatic cutting and welding device provided by the present invention can improve the splicing and welding quality, reduce the process difficulty, improve the processing efficiency, and save energy consumption.

[0047] Furthermore, if Figure 2-Figure 4As shown in the figure, the loading device 1 includes a frame 101, a first X-axis moving mechanism 102, a lifting mechanism 103, and a handling mechanical gripper 104 for grasping the sheet; at the top of the frame 101, there is a first X-axis moving mechanism 102 for driving the lifting mechanism 103 to move along the X-axis direction and a lifting mechanism 103 for driving the handling mechanical gripper 104 to move up and down along the Z-axis direction; at one end of the frame 101, there is a first stacking table 105 for stacking sheets, and at the other end, there is an input positioning device 2. Optimally, a sheet thickness detection device 106 is provided between the first stacking table 105 and the input positioning device 2, and the sheet thickness detection device 106 is fixed to the frame 101. The sheet thickness detection device 106 is located below the first X-axis moving mechanism 102, and a second stacking table 107 is provided below the sheet thickness detection device 106. In this embodiment, the handling mechanical gripper 104 grabs the sheet on the first stacking table 105, and the lifting mechanism 103 drives the handling mechanical gripper 104 to move upward, so as to lift the sheet to a certain height. Then, the first X-axis moving mechanism 102 moves the lifting mechanism 103 and the sheet along the X-axis direction to the position where the sheet thickness is to be detected. Then, the push cylinder is used to push the sheet thickness detection device 106 to move along the Y-axis direction until the sheet is located between the upper and lower distance sensors of the sheet thickness detection device 106, and the sheet thickness detection device 106 is used to detect whether the sheet thickness meets the requirements; when it is detected that the sheet thickness meets the requirements, the first X-axis moving mechanism 102 drives the lifting mechanism 103 to continue to move along the X-axis direction to move the sheet to the input positioning device 2, otherwise the sheet is placed on the second stacking table 107.

[0048] Furthermore, the first X-axis moving mechanism 102 in this embodiment includes a first X-axis slide rail, a first X-axis slide seat that can slide along the first X-axis slide rail, and a first X-axis driving mechanism for driving the first X-axis slide seat to slide along the first X-axis slide rail. The lifting mechanism 103 is fixed to the first X-axis slide seat; the lifting mechanism 103 includes a Z-axis slide rail, a Z-axis sliding plate that can slide along the Z-axis slide rail, and a Z-axis driving mechanism for driving the Z-axis sliding plate to slide along the Z-axis slide rail. Both the Z-axis slide rail and the Z-axis driving mechanism are fixed to the first X-axis slide seat, and the bottom of the Z-axis sliding plate is connected to the handling mechanical gripper 104. The driving mechanism can be driven by a motor. The handling mechanical gripper 104 in this embodiment is used to transport the sheet from the first stacking table 105 to the sheet input and positioning station. The handling mechanical gripper 104 is in the form of a vacuum chuck. The sheet is sucked up by the vacuum chuck and lifted to a certain height. The U-shaped sheet thickness detection device 106 is pushed out by the push cylinder until the sheet is placed in the middle of the U-shape. The sheet thickness detection device 106 calculates the sheet thickness dimension through the upper and lower distance sensors of the U-shape. If it is greater than the single-sheet thickness value defined by the system, it means that the currently detected sheet thickness does not meet the requirements or there are multiple sheets. In addition, multiple sensors are arranged near the vacuum chuck of the handling mechanical gripper 104 to detect whether the sheet is sucked up or detached during the handling process.

[0049] Furthermore, if Figure 5-Figure 7 As shown, the input positioning device 2 includes a positioning platform 201 for receiving the plate delivered by the loading device 1 and a conveying mechanism for conveying the plate to the cutting and welding auxiliary device 3. The conveying mechanism is arranged at the end of the input positioning device 2 away from the cutting and welding auxiliary device 3; the positioning platform 201 is provided with a Y-axis positioning mechanism for positioning the plate in the Y-axis direction; the conveying mechanism is provided with an X-axis positioning mechanism for positioning the plate in the X-axis direction. In this embodiment, one end of the positioning platform 201 is the cutting and welding auxiliary device 3, and the other end is provided with a conveying mechanism. The handling mechanical gripper 104 places the grasped plate on the positioning platform 201, and the plate is positioned on the positioning platform 201 by the Y-axis positioning mechanism and the X-axis positioning mechanism, and then the plate is clamped by the clamping mechanism of the conveying mechanism, and the plate is pushed to move in the X-axis direction by the conveying mechanism, and the plate is conveyed to the cutting and welding auxiliary device 3.

[0050] The positioning platform 201 of this embodiment is provided with a plurality of brushes 202 with low friction resistance arranged in a matrix, and the handling mechanical gripper 104 grabs the plate and places it on the brushes 202. Furthermore, the Y-axis positioning mechanism includes a Y-axis positioning roller 203, a first Y-axis moving mechanism 204 for driving the Y-axis positioning roller 203 to move along the Y-axis direction, a common roller 205, and a second Y-axis moving mechanism 206 for driving the common roller 205 to move along the Y-axis direction; a plurality of Y-axis positioning rollers 203 are installed on one side of the positioning platform 201 along the Y-axis direction, and a plurality of common rollers 205 are installed on the other side. In this embodiment, the first Y-axis moving mechanism 204 and the second Y-axis moving mechanism 206 have the same structure, both of which include a Y-axis cylinder, a Y-axis slide rail, and a Y-axis slide seat that can move along the Y-axis slide rail. The piston rod of the Y-axis cylinder is connected to the Y-axis slide seat, and the common roller 205 and the Y-axis positioning roller 203 are respectively fixed on the corresponding Y-axis slide seats, and the Y-axis slide seat is pushed by the Y-axis cylinder to move, thereby driving the roller to move in the Y-axis direction. In this embodiment, the Y-axis positioning roller 203 is pushed by the Y-axis cylinder to move to the positioning reference position along the Y-axis direction, and the common roller 205 is pushed by the low-thrust Y-axis cylinder to move between the two rows of brushes 202 along the Y-axis direction, and pushes the plate to the Y-axis positioning roller 203. Since the Y-axis cylinder thrust of the common roller 205 is less than the Y-axis cylinder thrust of the Y-axis positioning roller 203, when the plate contacts the Y-axis positioning roller 203, the position of the plate in the Y-axis direction is determined.

The second X-axis moving mechanism 207 includes a second X-axis slide rail, a second X-axis slide seat that can slide along the second X-axis slide rail, and a second X-axis driving mechanism for driving the second X-axis slide seat to slide along the second X-axis slide rail, and the moving frame 208 is fixed on the second X-axis slide seat. The second X-axis driving mechanism can be driven by a motor, and the second X-axis slide rail can be set between the two middle rows of brushes. When the plate is positioned in the Y-axis direction, the clamping claw 210 of the conveying mechanism opens and moves toward the plate along the X-axis direction. When the plate contacts the X-axis positioning roller 209 on the moving frame 208, the clamping claw 210 clamps, and the plate is positioned in the X-axis direction. The second X-axis moving mechanism 207 conveys the plate to the cutting and welding auxiliary device 3.

[0052] Furthermore, if Figure 8-Figure 9 As shown, the cutting and welding auxiliary device 3 includes a first clamping platform and a second clamping platform arranged along the X-axis direction; the first clamping platform and the second clamping platform are arranged opposite to each other, and a gap is provided between the first clamping platform and the second clamping platform for the cutting and welding integrated device 4 to cut and weld the plate; the first clamping platform is connected to the input positioning device 2, and the second clamping platform is connected to the roller bed conveyor device.

The first platform 301 in this embodiment is similar to the positioning platform 201 of the input positioning device 2, and is provided with a brush and a positioning roller. The arrangement of the brush is the same as that of the positioning platform 201, which is convenient for the conveying mechanism of the input positioning device 2 to continue to convey the plate in the X-axis direction, so that the first clamping mechanism 302 can clamp the plate when it is in the extreme position; the second platform 303 includes a plurality of rollers arranged in a matrix, which are flush with the rollers of the roller conveying device and rotate synchronously, so that the plate on the second platform 303 is transported to the roller conveying device.

The gear is connected to the gear shaft key, and the positioning plate is connected to the gear shaft key. The positioning plate is L-shaped, one side is parallel to the Y-axis, and the other side is perpendicular to the Y-axis and connected to the gear shaft key. The rack is driven up and down by the positioning drive cylinder, thereby driving the gear to rotate, and finally driving the positioning plate to rotate to achieve horizontal and vertical flipping. The first clamping platform and the second clamping platform move back to back to their respective extreme positions and keep the clamping mechanism in an open state, the positioning plate flips to a horizontal state, when the conveying mechanism of the input positioning device 2 delivers the plate onto the first platform 301 and contacts the positioning plate, the system can calculate the length of the plate, the plate front positioning mechanism 305 flips to a vertical state, and the conveying mechanism continues to convey it to the extreme position in the X+ axis direction, the piano-key type clamping mechanism of the first clamping platform clamps the plate and moves in the X+ axis direction to the travel limit position, the second clamping mechanism 304 clamps the steel plate, the first clamping mechanism 302 opens and moves toward the X- axis direction to the tail end of the plate and then clamps the plate, the second clamping mechanism 304 opens, the first clamping platform moves to the extreme position in the X+ axis direction, the second clamping mechanism 304 clamps the plate, and the first clamping mechanism 302 opens and moves to the extreme position in the X- axis direction.
