DETAILED DESCRIPTION

[0027] The following will refer to Figures 1 to 6 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0028] First embodiment:

[0029] A welding device for welding aluminum plates, such as Figure 1-Figure 3As shown, it includes a welding head 1 and a mounting body 7, a movable block 2 is provided on the welding head 1, and also includes an anti-collision shell 3, a roller 4 is provided at the bottom of the anti-collision shell 3, the outer surface of the movable block 2 is slidably matched with the inner wall of the anti-collision shell 3, and an oil storage cylinder 5 is provided on the top of the movable block 2, a cylinder body 6 is installed between the oil storage cylinder 5 and the mounting body 7, the cylinder body 6 is an oil cylinder, and the input end of the cylinder body 6 is fluid-conducted with the output end of the oil storage cylinder 5; an oil inlet pipe seat 8 and an oil outlet pipe seat 9 are provided on the oil storage cylinder 5, and a clearance groove 11 is provided on the anti-collision shell 3, and the oil inlet pipe seat 8 and the oil outlet pipe seat 9 extend out of the anti-collision shell 3 through two clearance grooves 11 respectively; a hose 33 is provided at the input end of the oil inlet pipe seat 8 and the output end of the oil outlet pipe seat 9, and the two hoses 33 are respectively connected to the external oil supply pipeline and the oil return pipeline. It should be noted that in this embodiment, the oil injection flow rate of the external oil supply pipeline to the oil storage cylinder 5 is a rated value.

[0030] During the process of the external oil supply pipeline filling oil into the oil storage cylinder 5 through the oil inlet pipe seat 8, the oil pressure in the oil storage cylinder 5 gradually increases, causing the free end of the cylinder body 6 to extend, driving the oil storage cylinder 5 with the movable block 2 and the welding head 1 away from the mounting body 7, thereby realizing the displacement of the welding head 1 toward the weldment.

[0031] like Figure 3 , Figure 4 and Figure 6 As shown, a deformation membrane 10 is provided on the oil outlet pipe seat 9, and a first clamping plate 12 and a second clamping plate 13 matching the deformation membrane 10 are slidably provided on the anti-collision shell 3. The first clamping plate 12 and the second clamping plate 13 are respectively located on both sides of the oil outlet pipe seat 9 and are arranged opposite to each other. The top ends of the first clamping plate 12 and the second clamping plate 13 close to each other are provided with protrusions 14; in the initial state, the protrusion 14 abuts against the deformation membrane 10, at which time the flow area in the oil outlet pipe seat 9 is in the minimum state, and the external oil supply pipeline is rated to fill the oil storage cylinder 5, that is, at this time, the pressure increase speed in the oil storage cylinder 5 is faster, and the free end of the cylinder body 6 extends faster, and at this time the welding head 1 Quickly approach the weldment (the anti-collision shell 3 will move with the welding head 1); when the welding head 1 moves to the point where the roller 4 on the anti-collision shell 3 contacts the weldment, the anti-collision shell 3 no longer moves. When the welding head 1 continues to move, the welding head 1 and the anti-collision shell 3 slide relative to each other, so that the deformation membrane 10 no longer corresponds to the protrusion 14, that is, the protrusion 14 no longer presses against the deformation membrane 10, so that the flow area in the oil outlet pipe seat 9 is increased, that is, the pressurization speed of the oil body in the oil storage cylinder 5 is reduced, and then the speed at which the free end of the cylinder body 6 extends is reduced, so that it is convenient to accurately control the displacement of the subsequent welding head 1 to prevent the welding head 1 from moving quickly and colliding with the weldment, thereby damaging the welding head 1 and the weldment.

[0032] like Figure 2 and Figure 3 As shown, a first spring 15 is installed between the inner top wall of the anti-collision shell 3 and the movable block 2 , and a second spring 16 is installed between the oil storage cylinder 5 and the mounting body 7 .

[0033] like Figure 4and Figure 6 As shown, a positioning frame 17 is provided on the side where the first clamping plate 12 and the second clamping plate 13 are away from each other, and the positioning frame 17 is fixedly connected to the outer surface of the anti-collision shell 3. A sliding rod 18 is slidably connected through the positioning frame 17. The side where the first clamping plate 12 and the second clamping plate 13 are away from each other is respectively fixedly connected to two sliding rods 18, and one end of one sliding rod 18 away from the first clamping plate 12 and the other end of the sliding rod 18 away from the second clamping plate 13 are both provided with a limiting cap 19; a third spring 20 is installed between the first clamping plate 12 and one of the positioning frames 17, a receiving block 21 is provided at the bottom end of the first clamping plate 12, and the second clamping plate 13 and the other positioning frame An electric spring device 22 is installed between 17. The electric spring device 22 is a prior art and is equivalent to an energized solenoid. Each turn of the spring is equivalent to a circular current. The current direction in each turn of the spring is the same. According to the mutual attraction between currents in the same direction, each turn of the spring attracts the adjacent springs. Therefore, the electric spring device 22 will shrink as a whole, and the shrinkage amount of the electric spring device 22 changes according to the current intensity. When the electric spring device 22 is expanded or contracted, the second clamping plate 13 is moved closer to or away from the give way groove 11, thereby increasing or reducing the force of the second clamping plate 13 against the deformable membrane 10, thereby realizing the adjustment of the flow area in the oil outlet pipe seat 9.

[0034] like Figure 3 and Figure 5 As shown, a solenoid valve 29 is provided on the top wall of the oil storage cylinder 5, and the oil storage cylinder 5 is fluidically connected to the cylinder body 6 through the solenoid valve 29; a heat conducting wire 32 is provided on the welding head 1, and the heat conducting wire 32 is made of metal with good thermal conductivity. The other end of the heat conducting wire 32 extends to the inside of the oil storage cylinder 5. During the welding operation of the device, part of the heat on the welding head 1 will be transferred to the oil body in the oil storage cylinder 5 through the heat conducting wire 32. Since the oil body in the oil storage cylinder 5 is in a state of continuous replacement, the welding head 1 can be continuously cooled down to prevent the welding head 1 from being too high, resulting in increased wear of the welding head 1, and to prevent the welding head 1 from transferring high temperature to other components after the high temperature, resulting in accelerated oxidation of other components.

[0035] In this embodiment, the mounting body 7 is installed on an external path driving device, and the path driving device can be a linear path driving device or a circular path driving device, such as a ball screw linear module, etc.; when the device in this embodiment is in use, the external oil supply pipeline quantitatively transports oil to the oil storage cylinder 5 through the oil inlet pipe seat 8, and then the oil is discharged through the oil outlet pipe seat 9. It should be noted that the flow area in the oil outlet pipe seat 9 is smaller than the flow area in the oil inlet pipe seat 8. Therefore, the oil pressure in the oil storage cylinder 5 will continue to rise, causing the free end of the cylinder body 6 to extend quickly (in the initial state, the solenoid valve 29 is in the open state). At the same time, the second spring 16 is stretched to store force. When the free end of the cylinder body 6 is extended, the oil storage cylinder 5 brings the movable block 2 and the welding head 1 closer to the welded part.

[0036] When the welding head 1 moves to the point where the roller 4 on the anti-collision shell 3 contacts the welding part, the anti-collision shell 3 stops moving. When the welding head 1 continues to move, the welding head 1 slides relative to the anti-collision shell 3 (at the same time, the first spring 15 is stretched to store force), and the oil outlet pipe seat 9 slides along the direction of the give way groove 11, so that the deformation membrane 10 no longer corresponds to the protrusion 14, that is, the protrusion 14 no longer presses against the deformation membrane 10, and the flow area in the oil outlet pipe seat 9 increases, which reduces the speed of the oil pressure increase in the oil storage barrel 5, that is, the extension speed of the free end of the cylinder body 6 is reduced, which is convenient for accurately controlling the subsequent displacement of the welding head 1.

[0037] After observing that the welding head 1 moves to the pre-welding position, the solenoid valve 29 is closed, that is, the extension amount of the free end of the cylinder body 6 is limited, and then the path driving device drives the mounting body 7 to move along the welding path, that is, the welding head 1 moves along the welding path and fully welds the pre-welding position.

[0038] Second embodiment:

[0039] Based on the first embodiment, the device is used for aluminum plate butt joint and needs to be welded with a long weld length, that is, the welding time is long. During the welding process, the aluminum plate butt joint may be misaligned due to various factors. For example, the aluminum plate is affected by the force of the clamp, and the aluminum plates exert pressure on each other, resulting in misalignment of the aluminum plate butt joint. Traditionally, the staff will first make multiple connections at the pre-welding point by manual spot welding, and then fully weld the pre-welding point to ensure the stability of the aluminum plate butt joint during the welding process. However, it is affected by factors such as the welding space. For example, the space under the aluminum plate is small, which is not convenient for manual spot welding. Therefore, the manual spot welding method is time-consuming and laborious, and greatly increases the workload of the staff. The device in the first embodiment does not have the function of automatic spot welding, so the following improvements are made:

[0040] like Figure 4As shown, an intermittent push mechanism is provided on one side of the anti-collision shell 3, and the roller 4 is linked with the intermittent push mechanism. When the driving part of the intermittent push mechanism abuts against the first clamping plate 12, the first clamping plate 12 moves in a direction away from the clearance groove 11; the intermittent push mechanism includes a rotating shaft 23 rotatably arranged on the anti-collision shell 3, the roller 4 is coaxially fixedly connected to the rotating shaft 23, a first pulley 24 is coaxially fixedly connected to the rotating shaft 23, and a second pulley 25 is rotatably connected to the anti-collision shell 3, the diameter of the second pulley 25 is larger than the diameter of the first pulley 24, and the first pulley 24 and the second pulley 25 are both The first pulley 24 is wound with the belt 26 and is linked to the second pulley 25 through the belt 26. In this embodiment, the number of rollers 4, belts 26 and first pulleys 24 is set according to demand; when the first pulley 24 rotates, the second pulley 25 is driven to rotate through the belt 26. It should be noted that since the diameter of the second pulley 25 is greater than the diameter of the first pulley 24, the rotation speed of the second pulley 25 is less than the rotation speed of the first pulley 24; a protective shell 34 is provided on the anti-collision shell 3, and the protective shell 34 is used to protect the second pulley 25.

[0041] like Figure 4 As shown, a one-way bearing 27 is rotatably provided on the anti-collision shell 3, the second pulley 25 is coaxially connected to the one-way bearing 27, a push rod 28 is provided on the output end of the one-way bearing 27, and the receiving block 21 matches the push rod 28. When the second pulley 25 rotates forward, the one-way bearing 27 rotates forward with the second pulley 25, and the push rod 28 rotates forward. When the second pulley 25 rotates reversely, the one-way bearing 27 will not rotate.

[0042] like Figure 3 and Figure 5 As shown, a first hydraulic detection device 30 is provided in the oil storage cylinder 5, a second hydraulic detection device 31 is provided in the cylinder body 6, and a controller is also included. The controller is not drawn, and the controller is a PLC controller. The electric spring device 22, the first hydraulic detection device 30 and the second hydraulic detection device 31 are all electrically connected to the controller; the PLC controller can control the current intensity on the electric spring device 22, thereby realizing the control of the contraction and extension amount of the electric spring device 22.

[0043] When the current intensity on the control electric spring device 22 increases, the electric spring device 22 contracts and pulls the second clamping plate 13 away from the yielding groove 11, and the resistance force of the second clamping plate 13 on the deformable membrane 10 decreases, so that the flow area of ​​the oil outlet pipe seat 9 increases and the oil pressure inside the oil storage cylinder 5 decreases; when the current intensity on the control electric spring device 22 decreases, the electric spring device 22 unfolds and pushes the second clamping plate 13 close to the yielding groove 11, and the resistance force of the second clamping plate 13 on the deformable membrane 10 increases, so that the flow area in the oil outlet pipe seat 9 decreases, and the oil pressure inside the oil storage cylinder 5 increases, thereby realizing the adjustment of the telescopic amount of the free end of the cylinder body 6, so that the staff can adjust the position of the welding head 1 according to needs.

[0044] When the device in this embodiment is in use, based on the welding head 1 in the first embodiment moving to the pre-welding position and the solenoid valve 29 being closed, the second hydraulic detection device 31 monitors the oil pressure in the cylinder body 6 at this time, and transmits the monitoring data to the controller. The oil pressure value at this time is set to a. The first hydraulic detection device 30 monitors the oil pressure in the oil storage barrel 5 at this time and transmits the data to the controller. By comparing the oil pressure values ​​of the two, the controller controls the current intensity on the electric spring device 22 to gradually increase. The electric spring device 22 contracts and pulls the second clamping plate 13 away from the yielding groove 11. The supporting force of the second clamping plate 13 on the deformation membrane 10 decreases, so that the flow area of ​​the oil outlet pipe seat 9 increases, and the oil pressure inside the oil storage barrel 5 decreases until the oil pressure value of the oil in the oil storage barrel 5 is monitored to be a, and the current intensity on the electric spring device 22 is stopped from increasing. At this time, the flow area value in the oil outlet pipe seat 9 is set to b.

[0045] Then, the solenoid valve 29 is opened again to make the fluid of the oil storage cylinder 5 and the cylinder body 6 conduct. Since the oil pressure inside the oil storage cylinder 5 and the cylinder body 6 is consistent at this time, the free end of the cylinder body 6 will not be retracted or expanded. Then, the path driving device drives the mounting body 7 to move along the welding path, that is, the welding head 1 and the anti-collision shell 3 move along the welding path. It should be noted that during the movement of the welding head 1 along the welding path, the roller 4 rolls along the surface of the aluminum plate, so that the rotating shaft 23 drives the first pulley 24 to rotate in the positive direction, and the second pulley 25 is driven to rotate in the positive direction through the belt 26. The one-way bearing 27 rotates in the positive direction and drives the push rod 28 to rotate in the positive direction. When the push rod 28 rotates to abut the receiving block 21, the first clamping plate 12 is driven to move away from the yielding groove 11 (at the same time, the third spring 20 is compressed and stored), and the deformable membrane 10 is no longer abutted by the first clamping plate 12. The deformable membrane 10 is reset and the flow area in the oil outlet pipe seat 9 is increased, so that the oil storage cylinder 5 The oil pressure in the cylinder 6 is rapidly reduced, and the second spring 16 is acted upon to pull the oil storage cylinder 5 away from the weld and cause the free end of the cylinder 6 to shrink rapidly, so that the welding head 1 is rapidly away from the weld. When the push rod 28 rotates to pass over the receiving block 21, the third spring 20 releases its force and presses against the first clamping plate 12 to reset. The first clamping plate 12 presses against the deformation membrane 10 again, so that the oil storage cylinder 5 and the cylinder 6 are gradually pressurized, and the free end of the cylinder 6 gradually extends out, and the welding head 1 approaches the weld again. It is worth noting that each time the welding head 1 moves close to the weld, since the first clamping plate 12 presses against the deformation membrane 10 again, the flow area value in the oil outlet pipe seat 9 is b, so the oil pressure in the oil storage cylinder 5 and the cylinder 6 can only increase to a or close to a, that is, the welding head 1 moves to the pre-welding position but the welding head 1 does not apply high pressure to the weld, so as to prevent the welding head 1 from pressing against the weld under high pressure, causing damage to the welding head 1 and the weld.

[0046] It should be noted that, under the tensile force of the first spring 15 , when the welding head 1 is away from the welding piece, the roller 4 will not be away from the welding piece, and the roller 4 is always in contact with the welding piece.

[0047] When the path driving device drives the welding head 1 to move along the welding path, the roller 4 continues to roll, and the welding head 1 constantly approaches or moves away from the weldment, thereby realizing intermittent welding; it is worth noting that the welding head 1 moves faster when it is away from the weldment, and moves slower when it is close to the weldment. Each time the welding head 1 reaches the welding point, it will move away from the weldment again after a period of time, realizing intermittent spot welding or small-segment welding of the pre-welding point by the welding head 1, thereby realizing the preliminary welding of the weldment by the device.

[0048] Then, when the path driving device drives the welding head 1 to move in the reverse direction along the welding path, the roller 4 rolls in the reverse direction, causing the rotating shaft 23 to rotate in the reverse direction with the first pulley 24, and the second pulley 25 to rotate in the reverse direction. Through the setting of the one-way bearing 27, the top rod 28 will not rotate at this time. Therefore, when the welding head 1 moves in the reverse direction along the welding path, the welding head 1 always corresponds to the pre-welding point, thereby realizing comprehensive welding of the pre-welding point.

[0049] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.
