Description

Technical Field

[0001] The present invention relates to the technical field of new energy automobile manufacturing, and in particular to a welding device for producing new energy automobiles. Background Art

[0002] With the rapid development of the new energy vehicle industry, the manufacturing precision and efficiency of its core component, the radiator, are becoming more and more stringent. As a key component to ensure the stable operation of key components such as automotive battery packs and motors, the welding quality of the radiator directly affects the heat dissipation efficiency and overall performance of the vehicle.

[0003] The radiator water tank is composed of metal parts such as the radiator core, upper water chamber and lower water chamber. When assembling the radiator, the two water chambers inserted at both ends of the radiator core need to be welded together with the radiator core.

[0004] A Chinese patent with a patent publication number of CN112264696A discloses a dual-gun automatic welding device for an automobile water tank radiator, comprising a base, a left and a right machine base, a first and a second mechanical arm, a transverse driving device, a wire feeding mechanism, a welding mechanism, a workpiece clamping device and a turning device; the left and the right machine base are respectively mounted on the left and right sides of the base, and the right machine base can move laterally under the drive of the transverse driving device; the first and the second mechanical arms are respectively mounted on the left and the right machine base, the wire feeding mechanism is matched with the welding mechanism, and the two sets of welding mechanisms are respectively mounted on the first and the second mechanical arms and driven by the mechanical arms to move along the weld for welding; two turning devices are provided, which are respectively mounted on the left and the right machine base for the overall turning of the workpiece clamping device; the workpiece clamping device comprises a first and a second clamping mechanism, and the two clamping mechanisms cooperate to clamp the workpiece.

[0005] The above-mentioned welding device only welds the water chamber and the radiator core together, but the metal parts of the radiator water tank are processed through multiple processes such as stamping and punching. The metal debris generated during the processing and the stamping oil used are easy to remain on the surface of the metal parts. The residual stamping oil not only makes it easier for the metal debris to adhere to the surface of the metal parts, but also easily absorbs dust and forms oil stains; and when the metal parts are exposed to the air, they may absorb moisture in the air, especially in an environment with high humidity and large temperature difference, a water film is easy to form on the metal surface; if these impurities are located at the weld and are not cleaned in time, it is easy to cause defects such as pores and cold welds in the weld during welding, reducing the strength and sealing of the weld, affecting the performance and life of the radiator, and if the workers check and clean before welding, the welding efficiency will be reduced to a certain extent. Therefore, in order to improve the welding quality and efficiency of the radiator water tank, it is necessary to provide a welding device with an automatic weld cleaning function.

DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1: A welding device for new energy vehicle production, such as Figure 1-Figure 3 As shown, it includes an electric slide 10, a slide seat 11, a conversion shaft 12, a fixed block 13, a wiping block 14, a welding gun seat 15, an automatic welding gun 16, a socket 21, a wiping seat 22 and a spring 23. There are two electric slides 10 in total. The electric slide 10 is slidably connected to the slide seat 11 in the horizontal direction. The electric slide 10 is used to drive the slide seat 11 to move back and forth. The two slide seats 11 are connected to the conversion shaft 12 in a damping rotation manner. The diameter of the middle part of the conversion shaft 12 is larger, and the diameters on both sides are slightly smaller. Two fixed blocks 13 are symmetrically fixed to the conversion shaft 12. Four sockets 20 are symmetrically opened on the upper and lower sides of the fixed block 13. Each socket 20 can be plugged with a socket 21. A wiping seat 22 is slidably connected to the two sockets 21 on the same side of the upper and lower sides. A spring 23 is sleeved on the guide rod 2 that is slidably connected to the socket 21. The spring 23 is used to push the socket 21 close to the fixed block 13 to prevent it from falling off. A wiping block 14 is fixedly connected to the wiping seat 22. The wiping block 14 is made of sponge material, and closed-cell sponge, open-cell sponge and nano sponge can be selected. A welding gun seat 15 is fixedly connected to the lower side of the sliding seat 11. An automatic welding gun 16 is slidably connected to the welding gun seat 15 in the horizontal direction. The automatic welding gun 16 is an automatic TIG welding gun in the prior art. TIG welding is also called non-melting inert gas shielded arc welding. When the wiping block 14 is out of contact with the heat sink, the conversion shaft 12 will rotate 180 degrees to automatically replace the wiping block 14, and the automatic welding gun 16 will adjust its position in the horizontal direction so that the welding position is always cleaned by the wiping block 14.

[0031] like Figure 3 , Figure 6 and Figure 7As shown, it also includes a positioning mechanism for adjusting the position of the automatic welding gun 16 according to the welding direction, the positioning mechanism is connected to the conversion shaft 12, the positioning mechanism includes a support sleeve 50, a connecting block 51, an active plate 52, a pull rod 53, a sliding sleeve 54, an auxiliary push block 55 and a main push block 56, the two sliding seats 11 are fixedly connected to the opposite ends of the support sleeve 50, a circular arc slideway is provided in the support sleeve 50, and the slideway and the conversion shaft 12 are coaxial, the connecting block 51 is slidably connected in the slideway of the support sleeve 50, the connecting block 51 is fixedly connected to the active plate 52, the active plate 52 is rotatably connected to the pull rod 53, the welding gun seat 15 is slidably connected to the sliding sleeve 54, the automatic welding gun 16 is fixed to the sliding sleeve 54, the sliding sleeve 54 is provided with a straight slideway, the pull rod 53 is rotatably connected to the active plate 52, the welding gun seat 15 is slidably connected ... 3 is slidably connected to the straight slideway on the sliding sleeve 54. Every time the conversion shaft 12 rotates 180 degrees, the active plate 52 will be driven to rotate 60 degrees, so that the sliding sleeve 54 and the automatic welding gun 16 are driven to move through the rotation of the active plate 52. A circular through hole coaxial with the conversion shaft 12 is opened on the active plate 52. The conversion shaft 12 passes through the circular through hole on the active plate 52. Two auxiliary push blocks 55 are fixedly connected in the circular through hole of the active plate 52. A main push block 56 is fixedly connected to the conversion shaft 12. The main push block 56 is located between the two auxiliary push blocks 55. When the main push block 56 contacts one of the auxiliary push blocks 55, the conversion shaft 12 rotates 120 degrees in the other direction to drive the main push block 56 to contact the other auxiliary push block 55.

[0032] When welding begins, place the assembled heat sink between the two electric slides 10 so that the two welds on the upper end of the heat sink are aligned with the two fixed blocks 13 on the conversion shaft 12. Taking the state in the figure as an example, the side where the conversion shaft 12 is located is the rear side, and the automatic welding gun 16 is located at the rear side of the fixed block 13. First, control the slide 11 to move forward. Since the wiping block 14 is made of soft material, the wiping block 14 will fit in contact with the weld surface during the forward movement of the slide 11, and the impurities on the weld will be dragged and wiped away by the wiping block 14. Since the automatic welding gun 16 is located at the rear side of the fixed block 13 at this time, the welding position of the automatic welding gun 16 has been cleaned by the wiping block 14. When the wiping block 14 is out of contact with the heat sink, Figure 3 and Figure 7From the perspective of FIG, the conversion shaft 12 will rotate counterclockwise 180 degrees, thereby rotating the used wiping block 14 on the lower side to the upper side, and rotating the unused wiping block 14 on the upper side to the lower side, so as to realize the automatic replacement of the wiping block 14 to ensure the cleaning effect of the weld. At the same time, the rotating shaft will drive the main push block 56 to rotate synchronously. When the conversion shaft 12 rotates 120 degrees, the main push block 56 contacts another auxiliary push block 55, and then the conversion shaft 12 drives the main push block 56 and the auxiliary push block 55 to rotate synchronously. The active plate 52 rotates the remaining sixty degrees counterclockwise, and the active plate 52 drives the automatic welding gun 16 to slide forward through the pull rod 53 and the sliding sleeve 54. When the conversion shaft 12 is rotated, the automatic welding gun 16 moves to the front side of the fixed block 13, and then the heat sink is rotated one hundred and eighty degrees. When the slide seat 11 slides backward to weld the weld at the other end of the heat sink, since the automatic welding gun 16 is located at the rear side of the fixed block 13 at this time, the position welded by the automatic welding gun 16 is also cleaned by the wiping block 14.

[0033] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, it also includes a replacement mechanism for automatically replacing the wiping block 14, the replacement mechanism is connected to the socket 21, the replacement mechanism includes a base 30, a reset plate 31, a second spring 32, a carrier frame 33, a slider 34, a vertical rod 35, a push rod 36, an arc plate 37, an auxiliary magnet 38 and a main magnet 39, the two bases 30 are fixedly arranged on the ground, the two electric slides 10 are fixedly connected to the two bases 30, the base 30 is slidably connected with a reset plate 31 in the horizontal direction, and the reset plates 31 on the two bases 30 are symmetrically arranged, the reset plate 31 and the guide rod slidably connected to the base 30 are sleeved with a second spring 32, and the two reset plates 31 will compress the second spring 32 when they move back to back, the reset plate 31 is fixedly connected to the reset plate 31, and the arc plate 37 is semicircular, and two groups of carrier frames 33 are fixedly connected to the reset plate 31 in a left-right symmetrical manner, each group of carrier frames 33 is two, and the two carrier frames 33 in the same group are fixedly connected to the reset plate 31. 3, an arc-shaped slideway is provided at one end opposite to the other end, and both ends of the slideway are open. The carrier frame 33 is used to carry the wiping seat 22 after use. Two sliders 34 are symmetrically fixed on the wiping seat 22. When the conversion shaft 12 and the arc plate 37 are in contact and rotated, the sliders 34 on the wiping seat 22 can slide into the slide groove on the carrier frame 33. A vertical rod 35 is fixed on the socket 21. Two sets of push rods 36 are fixedly arranged on each base 30 symmetrically. There are two push rods 36 in the same group, and the two push rods 36 in the same group are symmetrically arranged. The push rods 36 are used to squeeze the vertical rod 35 to drive the socket 21 to disengage from the socket 20, so that the upper socket 21 and the wiping seat 22 stay on the carrier frame 33; a main magnet 39 is fixedly connected to the carrier frame 33, and a secondary magnet 38 is fixedly connected to the end of the slider 34 away from the wiping seat 22. The main magnet 39 is used to attract the secondary magnet 38 to fix the wiping seat 22 on the carrier frame 33.

[0034] When the sliding seat 11 slides forward, after the wiping block 14 and the heat sink are out of contact, the conversion shaft 12 will contact the arc plate 37 on the rear reset plate 31. At this time, the socket 21 carried by the frame 33 is just aligned with the socket 20 on the upper side of the fixed block 13. Then the sliding seat 11 continues to slide backward, and the conversion shaft 12 will push the reset plate 31 to move forward synchronously through the arc plate 37. The second spring 32 will be compressed. When the frame 33 on the reset plate 31 moves forward, it will drive the wiping seat 22 and the socket 21 carried thereon to move synchronously, so that the vertical rod 35 and the push rod 36 on the socket 21 gradually lose contact, and the compressed state The second spring 32 will push the two sockets 21 to move relative to each other, thereby driving the socket 21 on the carrier frame 33 to be inserted into the socket 20 on the upper side of the fixed block 13, and then the conversion shaft 12 will start to rotate 180 degrees again, thereby rotating the upper wiping seat 22 and the wiping block 14 to the lower side. At the same time, the lower wiping seat 22 and the wiping block 14 that has just been used are rotated to the upper side, and the slider 34 on the wiping seat 22 will slide into the slide groove on the carrier frame 33. When the rotation of the conversion shaft 12 is completed, the secondary magnet 38 on the slider 34 is just opposite to the main magnet 39, and the wiping seat 22 is fixed in place by the magnetic force between the main magnet 39 and the secondary magnet 38. The wiping seat 22 and the socket 21 carried by the carrier frame 33 will move forward synchronously, that is, the wiping seat 22 and the socket 21 rotated to the top of the fixed block 13 will move forward synchronously, and the vertical rod 35 on the socket 21 above the fixed block 13 will gradually contact with the push rod 36, and the push rod 36 will make the two sockets 21 on the upper side move back to each other through the vertical rod 35, thereby driving the socket 21 on the upper side to disengage from the socket 20 of the fixed block 13, so that when the slide 11 moves backward, the wiping block 22 and the socket 21 just used will move forward synchronously. 14 will be placed on the carrier frame 33 and fixed by the magnetic force of the main magnet 39 and the auxiliary magnet 38. The wiping block 14 that has just been used will not move synchronously with the slide 11, which is convenient for drying or replacing the wiping block 14 that has just been used on the carrier frame 33 to ensure the cleaning effect of the weld position, and the equipment can always keep in operation to improve welding efficiency; the state shown in the figure is that the slide 11 has completed the replacement of the wiping block 14 on the rear side, at this time the slide 11 is moving forward, and the reset plate 31 on the rear side has completed the reset, and the conversion shaft 12 is about to lose contact with the arc plate 37 on the rear reset plate 31.

[0035] like Figure 1 and Figure 3As shown, it also includes a rack 40 and a gear 41 for driving the conversion shaft 12 to rotate. Each machine base 30 is fixed with a rack 40, but the positions of the racks 40 on the two machine bases 30 are different. The conversion shaft 12 is rotatably connected to two gears 41 through two one-way bearings. Each gear 41 cooperates with the rack 40 on one of the machine bases 30. The installation directions of the two one-way bearings are different, so that the two racks 40 can drive the conversion shaft 12 to rotate in different directions through the corresponding gears 41.

[0036] During the forward movement of the slide 11, the rack 40 on the front base 30 will mesh with the inner gear 41, and the conversion shaft 12 will be driven to rotate 180 degrees counterclockwise through the inner gear 41. Under the action of the one-way bearing, the inner gear 41 can only drive the conversion shaft 12 to rotate counterclockwise; during the backward movement of the slide 11, the rack 40 on the rear base 30 will mesh with the outer gear 41, and the conversion shaft 12 will be driven to rotate 180 degrees clockwise through the outer gear 41. Under the action of the one-way bearing, the outer gear 41 can only drive the conversion shaft 12 to rotate clockwise.

[0037] Embodiment 3: Based on embodiment 2, Figure 1 and Figure 8 As shown, it also includes a turning table 60, a turning frame 61 and a servo motor 62 for driving the heat dissipation water tank to rotate. The turning table 60 is fixedly arranged on the ground between the two machine bases 30. The turning frame 61 is rotatably connected to the turning table 60.

The main structure of the turning frame 61 is a U-shaped structure, so that the heat dissipation water tank can be clamped on the turning frame 61.

[0038] like Figure 1 and Figure 8 As shown, it also includes a positioning frame 63, a No. 3 spring 64 and a positioning plate 65 for positioning the heat dissipation water tank. Two symmetrically arranged positioning frames 63 are slidably connected to the flip frame 61 in the horizontal direction. A No. 3 spring 64 is sleeved on the guide rod where the positioning frame 63 and the flip frame 61 are slidably connected. The No. 3 spring 64 is used to push the two positioning frames 63 to move away from the heat dissipation water tank. A positioning plate 65 is fixedly connected to the welding gun seat 15. The positioning plate 65 is used to squeeze the positioning frame 63 toward the heat dissipation water tank for positioning.

[0039] Insert the assembled heat sink into the flip frame 61 in advance. During the movement of the slide 11, the positioning plate 65 will contact the positioning frame 63, and the positioning plate 65 will make the two positioning frames 63 move relative to each other through the extrusion effect, so as to position the heat sink on the flip frame 61 and improve the welding accuracy. The No. 3 spring 64 will be compressed. When the positioning plate 65 and the positioning frame 63 are out of contact, the compressed No. 3 spring 64 will push the two positioning frames 63 to move away from the heat sink to facilitate the placement of the heat sink; when the two welds on the upper end of the heat sink are welded, and the wiping block 14 is moved out of the rotation range of the heat sink, the flip frame 61 is driven by the servo motor 62 to rotate 180 degrees to facilitate the welding of the two welds on the other end of the heat sink.

[0040] like Figure 1 and Fig. 9 As shown, it also includes a heat drying rack 70 and a hot air blower 71 for drying the wiping block 14. Two groups of heat drying racks 70 are symmetrically fixed on the machine base 30, and each group of heat drying racks 70 has two heat drying racks. The heat drying racks 70 are located on the upper side of the carrier frame 33. The four push rods 36 on the machine base 30 are correspondingly fixed to the lower end of each heat drying rack 70. The hot air blower 71 is fixed to the heat drying rack 70. The hot air blower 71 is a blower that can blow hot air in the prior art. When the reset plate 31 is reset, the wiping blocks 14 carried by each group of carrier frames 33 are located between a group of heat drying racks 70.

[0041] The wiping block 14 placed on the carrier frame 33 is located between two hot air blowers 71. The hot air blower 71 can blow out hot air and dry the wiping block 14 to ensure that the wiping block 14 is in a dry state each time it wipes the weld, and use wind force to blow off solid impurities on the surface of the wiping block 14 to improve the cleaning effect of the weld.
