Description

Technical Field

[0001] The invention relates to the technical field of sheet metal welding, and in particular to butt welding equipment suitable for metal product processing. Background Art

[0002] In the process of sheet metal processing, it is often necessary to weld various sheet metal parts. The most common ones are horizontal and vertical butt welding. The welding tooling is a set of welding fixing, pressing and positioning fixtures. It is mainly used for welding various weldable materials, welding of large, medium and small materials. The welding tooling is generally controlled by using power mechanisms such as cylinders to clamp and fix the sheet metal parts, which is convenient for the welding gun to weld the sheet metal parts. Sheet metal components are mainly welded by welding robots during the welding process, especially the flanged sheet metal parts that need to be welded after bending. The positioning effect is particularly important.

[0003] For example, in the prior art, a sheet metal welding tool and a flanged sheet metal welding method with publication number CN117226406A are disclosed. The welding tool can adapt itself according to the size of the sheet metal to be welded, ensuring the appropriate force for each sheet metal to be welded in the same batch, without adjusting the position of the clamping unit, which greatly improves the clamping efficiency and clamping accuracy. However, the special setting of multiple clamping units can only complete the butt welding of rectangular and 90° vertically flanged sheet metal parts. For polygonal and flanged sheet metal parts with flanges at different angles, it is difficult to achieve a multi-directional flanged butt welding processing effect.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0018] The beneficial effects of the present invention are as follows:

[0019] (1) The present invention uses a material mechanical arm to grab the metal sheet metal after the flanging process and place it on a rotating disk. First, a photoelectric sensor is used to collect data on the flanging position of the sheet metal, and the collected control signal is transmitted to a controller in the control panel. The controller adjusts the deflection angle of the rotating disk to achieve parallel positioning of a flange on one side of the qualified flanging of the sheet metal and the flip plate. Secondly, the electric push rod is used to push the moving plate to move, causing the flip plate to deflect to the same angle as the current flanging. After that, the rotating disk is moved horizontally to cause the flanging parallel to the flip plate and the deflected flip plate to collide with each other, so as to achieve the abutment and docking of the current flanging with the qualified flanging, and then the welding mechanical arm is used to complete the welding process at the flanging docking point. In addition, with the help of the movement of the moving plate, a negative pressure environment is formed inside the suction cylinder, so as to achieve the adsorption and fixation of the metal sheet metal on the rotating disk, thereby avoiding the problem of sheet metal position movement during butt welding, which leads to the inability to accurately butt weld.

[0020] (2) The present invention uses auxiliary plates and auxiliary rods that are slidably installed on both sides of the flip plate, which can not only stabilize the flanges of different lengths, but also avoid blocking the outer area of ​​the flange joint, thereby causing the problem of external welding interference in the joint area; and in the process of the sheet metal flange contacting with the flip plate, the pressure change value between the flip plate and the sheet metal is monitored by the pressure sensor, and the obtained data is compared and analyzed with the preset value in the controller. When the collected pressure value is greater than the preset value, the slow horizontal movement of the rotating disk is automatically stopped, and combined with the adjustment of the different deflection angles of the flip plate, the joint processing of flanges at different angles can be realized, thereby further improving the scope of application of the present device.

[0034] 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.

[0035] Example 1: Please refer to Figure 1-Figure 7 As shown, in the prior art, for polygonal and flanged sheet metal parts with different flange angles, it is difficult to achieve multi-directional flanged butt welding processing effects, which can be solved by the following solutions:

[0036] The butt welding equipment suitable for metal product processing in this embodiment includes a processing table 1, which is a square tubular structure and has a partition plate inside to realize the installation of the adjustment component 2 and the suction cylinder 212. The adjustment component 2 and the flip component 3 are arranged on the processing table 1, and a control panel 11 is bolted on the processing table 1;

[0037] The adjustment component 2 includes a rotating disk 21 for driving the sheet metal to rotate, and is used to rotate the flanges at different positions on the sheet metal to the butt welding area, thereby realizing multi-directional butt welding processing of polygonal flanged sheet metal parts, and a sliding frame 22 and a sliding seat 23 for adjusting the horizontal movement of the rotating disk 21. The sliding frame 22 and the sliding seat 23 are used to adjust the position of the rotating disk 21 on the horizontal plane, so that the flange of the sheet metal is caused to collide with the flip plate 32 deflected at the same angle, so as to achieve the butt effect, and at the same time, the position of the welding point is adjusted, so that the welding point is placed in the welding area for effective welding;

[0038] A mounting cavity 24 is provided at the top of the sliding seat 23 for rotationally mounting the rotating disk 21. On the one hand, it is used for a rotationally sealed connection with the rotating disk 21. On the other hand, the negative pressure state in the mounting cavity 24 is combined with the adsorption holes 26 to fix the position of the sheet metal. An air intake pipe 25 is fixedly connected to the bottom of the mounting cavity 24 for discharging the air in the mounting cavity 24. A plurality of adsorption holes 26 are provided through the top of the rotating disk 21. A sealing ring is embedded and installed on the top of the rotating disk 21 and on the outer side of the corresponding adsorption holes 26 to increase the sealing between the adsorption holes 26 and the sheet metal, thereby improving the adsorption and fixation effect.

[0039] The flip assembly 3 includes two sets of ear plates 31 fixedly connected to the top of one side of the processing table 1, which are used for installing the flip plate 32 on one side of the top of the processing table 1, and the tops of the two sets of ear plates 31 are embedded with photoelectric sensors. The connection line between the two sets of photoelectric sensors is parallel to the flip plate 32, which is used to detect the position of the sheet metal flange, whether it is parallel to the flip plate 32, so as to ensure the efficient fitting effect of the flip plate 32 and the sheet metal flange;

[0040] A flip plate 32 for butting the flanged edge of the sheet metal is rotatably installed between the ear plates 31 through a rotating shaft, and a push plate 33 is slidably connected on the processing table 1 to drive the flip plate 32 to rotate and cooperate with the installation cavity 24 to adsorb and fix the sheet metal. During the flanging process of the sheet metal before butt welding, one of the flanges on the metal sheet metal is flanging with a qualified angle, and the flange on one side of the flange is used as the starting point, and the remaining flanges and the previous flange are butt-welded in turn;

[0041] The photoelectric sensors on the two sets of ear plates 31 collect data on the flange position of the sheet metal, and transmit the collected control signals to the controller in the control panel 11. The controller controls the motor 3 211 to drive the metal sheet metal to deflect, so that a flange located on the qualified flange side of the sheet metal is parallel to the flip plate 32.

[0042] Fixed frames 12 are welded on both sides of the processing table 1 for installing a material robot arm 13 and a welding robot arm 14, and the welding robot arm 14 and the flip assembly 3 are located on the same side of the processing table 1, and the two sets of fixed frames 12 are respectively installed with the material robot arm 13 and the welding robot arm 14, the material robot arm 13 is installed with a material suction cup, and the welding robot arm 14 is installed with a welding gun. The controller in the control panel 11 controls the material robot arm 13 to carry the material suction cup to absorb and grab the metal sheet metal after flanging processing, and place the metal sheet metal on the rotating disk 21, and controls the welding robot arm 14 to carry the welding gun to weld the flanging docking position.

[0043] The two sides of the sliding frame 22 are symmetrically connected with sliders 1 that slide with the processing table 1. A sliding groove 1 that slides with the slider 1 is opened on the inner wall of the processing table 1, which is used to ensure the stable horizontal movement of the sliding frame 22, and the sliding frame 22 carries the movement of the rotating disk 21 on the Y axis to achieve the adjustment of the welding point position. A screw rod 27 that is threadedly connected to the corresponding slider 1 is rotatably connected to the processing table 1. A motor 28 for driving the screw rod 27 to rotate is bolted on the processing table 1. The controller in the control panel 11 controls the motor 28 to drive the screw rod 27 to rotate, so that the sliding frame 22 moves horizontally along the Y axis.

[0044] The two sides of the sliding seat 23 are symmetrically connected with the sliding block 22, and the inner wall of the sliding frame 22 is provided with a sliding groove 2 for sliding with the sliding block 2, which is used to ensure the stable horizontal movement of the sliding seat 23, and the sliding seat 23 carries the movement of the rotating disk 21 on the X-axis to achieve the interference between the flange of the sheet metal and the flip plate 32 after fixing;

[0045] A screw rod 29 is rotatably connected to the sliding frame 22 and is threadedly connected to the corresponding sliding block 2. A motor 210 for driving the screw rod 29 to rotate is bolted on the sliding frame 22. A motor 3 211 for driving the rotating disk 21 to rotate is bolted in the mounting cavity 24. The controller in the control panel 11 controls the motor 210 to drive the screw rod 29 to rotate, causing the sliding seat 23 to move horizontally along the X-axis, causing the flange parallel to the flip plate 32 to collide with the deflected flip plate 32, thereby completing the collision and docking of the current flange with the qualified flange.

[0046] The top of the processing table 1 is fixedly connected with a suction cylinder 212 connected to the suction pipe 25, and the piston block 213 is slidably connected inside the suction cylinder 212. The piston block 213 is fixedly connected with a U-shaped frame 215 through a support rod 214. The bottom of the suction cylinder 212 is fixedly connected with a limit plate slidably connected with the support rod 214, which is used to increase the sliding stability of the piston block 213 in the suction cylinder 212 and avoid the problem of increasing wear on the piston block 213 and reducing the service life.

[0047] The piston block 213 moves downward in the suction cylinder 212, and the gas in the installation cavity 24 is extracted through the suction pipe 25, and the placed metal sheet metal is adsorbed and fixed through the adsorption holes 26 on the rotating disk 21, and the inside of the U-shaped frame 215 is fixedly connected to a guide rod 216.

[0048] Two sets of slide rails are bolted on the outer wall of the processing table 1 to achieve stable lifting and lowering movement of the U-shaped seat 34. The U-shaped seat 34 slides between the slide rails, and a guide rod 2 35 is fixedly connected inside the U-shaped seat 34, and a toothed plate 36 is fixedly connected to the top of the U-shaped seat 34.

[0049] The push plate 33 is provided with an L-shaped guide groove 1 37 slidably connected to the guide rod 1 216, and an L-shaped guide groove 2 38 slidably connected to the guide rod 2 35. An electric push rod 39 is fixedly connected between the push plate 33 and the inner side wall of the processing table 1. When the piston rod of the electric push rod 39 is in a fully retracted state, the guide rod 1 216 is located at the highest point of the oblique section in the L-shaped guide groove 1 37, and the guide rod 2 35 is located in the horizontal section in the L-shaped guide groove 2 38.

[0050] The electric push rod 39 is controlled to drive the push plate 33 to move, and the guide rod 216 in the U-shaped frame 215 is guided by the oblique section in the L-shaped guide groove 37, so that the U-shaped frame 215 and the support rod 214 carry the piston block 213 to move downward in the suction cylinder 212, so that a negative pressure environment is formed inside the suction cylinder 212, and the gas in the installation cavity 24 is extracted through the suction pipe 25, and then the placed metal sheet metal is adsorbed and fixed through the adsorption holes 26 on the rotating disk 21;

[0051] After completing the parallel positioning of the sheet metal, the controller in the control panel 11 controls the piston rod of the electric push rod 39 to extend again, and the guide rod 1 216 in the U-shaped frame 215 slides in the horizontal section in the L-shaped guide groove 1 37 to continuously maintain the fixed state of the sheet metal, and the guide rod 2 35 in the U-shaped seat 34 enters the oblique section from the horizontal section of the L-shaped guide groove 2 38, prompting the U-shaped seat 34 to move upward.

[0052] A transmission rod is rotatably connected to the processing table 1, and a sprocket is fixedly connected to one end of the transmission rod and the rotating shaft. The sprockets are connected by chain transmission. A gear 310 meshing with the tooth plate 36 is fixedly connected to the transmission rod. The transmission rod, sprocket and chain are arranged to reduce the installation height of the gear 310, so as to avoid the problem of lifting the metal sheet metal when the U-shaped seat 34 drives the tooth plate 36 to move upward, thereby avoiding the problem of motion interference;

[0053] The toothed plate 36 and the gear 310 are meshed to drive the transmission rod to rotate, and the transmission rod, in conjunction with the sprocket and the chain, drives the flip plate 32 to rotate. The flip plate 32 carries the auxiliary plates 311 and the auxiliary rods 313 on both sides to deflect to the same angle as the current flanging.

[0054] Example 2: Please refer to Figure 7 and Figure 8 As shown, the following solutions can be used to solve the problem that the flip plate is difficult to stably resist the longer flange, which leads to excessive horizontal movement of the rotating disk and deformation of the flange:

[0055] In this embodiment, auxiliary plates 311 are symmetrically installed on both sides of the flip plate 32, and a clearance groove for the auxiliary plate 311 to move is provided on the flip plate 32, and a T-block is fixedly connected to the auxiliary plate 311, and a sliding groove is provided on the flip plate 32 to be slidably connected to the corresponding T-block, and the T-block and the sliding groove are used to realize the sliding connection between the auxiliary plate 311 and the flip plate 32;

[0056] A spring 312 is fixedly connected between the auxiliary plate 311 and the flip plate 32, which can realize the reset of the auxiliary plate 311 after movement and prevent the auxiliary plate 311 from separating from the flip plate 32. A plurality of auxiliary rods 313 are fixedly connected to one side of the auxiliary plate 311 at equal intervals along its length direction. The flip plate 32, the auxiliary rods 313 and one side of the auxiliary plate 311 are in the same horizontal plane, so that after the three contact with the flange of the sheet metal, there will be no problem of uneven resistance force.

[0057] During the process of the sheet metal flange abutting against the flip plate 32, the pressure change value between the flip plate 32 and the sheet metal is monitored by the pressure sensor embedded in the flip plate 32, and the obtained data is compared and analyzed with the preset value in the controller. When the collected pressure value is greater than the preset value, the controller stops the slow horizontal movement of the rotating disk 21, completes and maintains the docking between adjacent flanges, wherein the preset pressure value is the excessive pressure value that occurs when the flange in contact with the flip plate 32 abuts against the adjacent flange on one side, and limits the "rotation" of the current flange, and follows the slow horizontal movement of the rotating disk 21;

[0058] When the welding robot arm 14 carries a welding gun to weld the outer side of the docking position, the welding robot arm 14 places the welding gun between the two sets of auxiliary rods 313 at the welding position, and through the sliding between the auxiliary plate 311 and the flip plate 32, it can avoid the auxiliary rods 313 from blocking the external welding area, thereby realizing the welding process of the inside and outside after the flanging docking, and after the welding robot arm 14 separates the welding gun from the auxiliary rods 313, the auxiliary plate 311 is reset under the elastic action of the spring 312;

[0059] For the butt welding between the remaining two adjacent sets of flanges, the controller in the control panel 11 first drives the motor 1 28 and the motor 2 210 to drive the rotating disk 21 to move horizontally, so as to move the sheet metal and the flip plate 32 away from each other, and then repeats the above steps 3 to 5 to complete the butt welding between the remaining two adjacent sets of flanges in turn.

[0060] Example 3: Please refer to Figure 1-Figure 8 As shown, the present invention also proposes a method for using a butt welding device suitable for metal product processing, comprising the following steps:

[0061] Step 1: During the flanging process, one of the flanging edges on the metal sheet is flanging at a qualified angle;

[0062] Step 2: The controller in the control panel 11 first controls the material mechanical arm 13 to carry the material suction cup to absorb and grab the metal sheet metal after the flanging process, and place the metal sheet metal on the rotating disk 21, and then controls the electric push rod 39 to drive the push plate 33 to move, and the guide rod 216 in the U-shaped frame 215 is guided by the oblique section in the L-shaped guide groove 37, so that the U-shaped frame 215 combined with the support rod 214 carries the piston block 213 to move downward in the suction cylinder 212, and the gas in the installation cavity 24 is extracted through the suction pipe 25, and then the placed metal sheet metal is absorbed and fixed through the suction hole 26 on the rotating disk 21;

[0063] Step 3: The photoelectric sensors embedded in the two sets of ear plates 31 are used to collect data on the flange position of the sheet metal part, and the collected control signals are transmitted to the controller in the control panel 11. The controller controls the motor 3 211 to drive the metal sheet metal part to deflect, so that a flange located on the side of the qualified flange of the sheet metal part is parallel to the flip plate 32;

[0064] Step 4: After the sheet metal is positioned and fixed, the controller in the control panel 11 controls the piston rod of the electric push rod 39 to extend again, and the guide rod 1 216 in the U-shaped frame 215 slides in the horizontal section in the L-shaped guide groove 1 37 to keep the sheet metal fixed. The guide rod 2 35 in the U-shaped seat 34 enters the oblique section from the horizontal section of the L-shaped guide groove 2 38, so that the U-shaped seat 34 moves upward, and the transmission rod is driven to rotate through the meshing of the tooth plate 36 and the gear 310. The transmission rod is combined with the sprocket and the chain to drive the flip plate 32 to rotate, and the flip plate 32 carries the auxiliary plates 311 and the auxiliary rods 313 on both sides to deflect to the same angle as the current flanging;

[0065] Then, the controller in the control panel 11 controls the motor 1 28 and the motor 2 210 to respectively drive the screw 1 27 and the screw 2 29 to rotate, and adjusts the position of the rotating disk 21 on the X-axis and the Y-axis, so that the flange parallel to the flip plate 32 and the deflected flip plate 32 collide with each other, thereby completing the collision and docking of the current flange with the qualified flange;

[0066] Step 5: During the process of the sheet metal flange colliding with the flip plate 32, the pressure change value between the flip plate 32 and the sheet metal is monitored by the pressure sensor embedded in the flip plate 32, and the obtained data is compared and analyzed with the preset value in the controller. When the collected pressure value is greater than the preset value, the controller stops the slow horizontal movement of the rotating disk 21 to complete and maintain the docking between adjacent flanges;

[0067] The rear control welding robot arm 14 carries a welding gun to weld the inner side of the docking position. When welding the outer side of the docking position, the welding gun is placed between the two sets of auxiliary rods 313 at the welding position, and the auxiliary plate 311 slides with the flip plate 32 to avoid the auxiliary rods 313 from blocking the external welding area, thereby completing the welding process of the inner and outer sides after the flanged docking.

[0068] Step 6: For the butt welding between the remaining two adjacent sets of flanges, first, the controller in the control panel 11 drives the motor 1 28 and the motor 2 210 to drive the rotating disk 21 to move horizontally, so that the sheet metal and the flip plate 32 are separated, and then the above steps 3 to 5 are repeated to complete the butt welding between the remaining two adjacent sets of flanges in turn. Then, the electric push rod 39 drives the push plate 33 to completely reset, releases the adsorption and fixation of the metal sheet metal, and unloads and loads the materials through the material robot 13.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
