Description

Technical Field

[0001] The present invention relates to the technical field of welding, and in particular to a welding processing device for automobile parts. Background Art

[0002] The horn is a car's acoustic signaling device. While driving, the driver, according to needs and regulations, emits necessary audible signals to warn pedestrians and attract the attention of other vehicles, ensuring traffic safety. A horn consists of a frame, T-irons, magnets, and guide rings. The frame supports and secures the other components, and during horn production, some components are welded to the frame.

[0003] Most existing welding tables are composed of a placement table, a welding gun, a fixing plate and a mounting slot. When assembling and welding the loudspeaker, the basin frame is first placed in the mounting slot on the top of the mounting table, and then the guide ring is placed in the basin frame and the guide ring is made coaxial with the basin frame. The guide ring and the basin frame are then welded together using a welding gun. During the welding process, the welder needs to manually rotate the basin frame continuously to completely weld the guide ring and the basin frame together. However, in the process of rotating the basin frame, the position of the basin frame and the guide ring inside it may shift, which may cause the welding position of the welding gun to shift, affecting the welding effect. Moreover, it is difficult to make the basin frame rotate at a uniform speed when manually rotating it, resulting in uneven welding at the connection between the guide ring and the basin frame, thereby affecting product quality. Summary of the Invention

The air cylinder is installed inside the lifting frame, the fixed frame is fixedly connected to the bottom of the air cylinder, the welding torch is fixedly connected to the fixed frame, and the air cylinder and the welding torch are connected by an air duct. When the lifting frame descends, the tightening and rotating assembly tightens the guide ring outside the positioning cylinder.

[0010] Preferably, the tightening and rotating assembly includes a sliding support block, a support spring, a sliding tightening block, a tension spring, a rotating motor and a pressure plate. The sliding support block is slidably connected inside the positioning cylinder, the sliding support block and the positioning cylinder are connected by a support spring, the sliding tightening block is slidably connected inside the positioning cylinder, the two sliding tightening blocks are connected by a tension spring, through holes are opened in the inner wall of the positioning cylinder corresponding to the positions of the sliding tightening blocks, the rotating motor is installed inside the support frame, the output shaft of the rotating motor is connected to the positioning cylinder, and the pressure plate is fixedly connected to the fixed frame.

[0011] Preferably, it further includes a flipping gear and a lifting rack. The lifting rack is fixedly connected to the lifting frame, the flipping gear is fixedly connected to the support frame, there is a large rotational resistance between the support frame and the rotating workbench, and the support frame will not rotate without external force.

[0012] Preferably, it further includes a side support, a rotating rod, a transmission belt, a material storage cylinder, a fixed frame, a limiting ring and a feeding arc rod. The side support is fixedly connected to the inner bottom plate of the fixed support, the rotating rod is rotatably connected inside the side support, the rotating shaft and the rotating rod are connected by a transmission belt, the fixed frame is fixedly connected inside the side support, the limiting ring is fixedly connected inside the fixed frame, the material storage cylinder is fixedly connected inside the side support, the feeding arc rods are evenly and spacedly fixedly connected to the rotating rod, and through holes are opened in the inner bottom surface of the fixed frame.

[0013] Preferably, it further includes a lifting push block, a sliding clamping rod and a clamping spring. The lifting push block is fixedly connected to the lifting frame, the sliding clamping rod is slidably connected inside the fixed frame, the sliding clamping rod and the fixed frame are connected by a clamping spring, and the sliding clamping rod cooperates with the feeding arc rod to clamp the guide ring.

[0014] The beneficial effects of the present invention are as follows: 1. This device conducts processes such as raw material positioning, raw material transportation, and rotary welding through an automated production line. Four support frames are set on the rotary worktable to form a four-station processing platform, enabling multiple processes to be carried out simultaneously, saving labor costs, and improving work efficiency at the same time. The positioning cylinder in the positioning component is used to define the positions of the basin frame and the guide ring, so as to quickly place the basin frame and the guide ring concentrically on the support frame. The automatic material taking mechanism automatically places the basin frame on the support frame, and the welding mechanism automatically welds the basin frame and the guide ring together.

[0015] 2. During the process of picking up the basin frame, the sliding baffle and the wedge-shaped stop are arranged alternately, and under the action of the transmission gear and the transmission rack, the sliding baffle and the wedge-shaped stop move in different directions to support basin frames of different heights, ensuring that only one basin frame is placed on the support frame each time.

[0016] 3. When the rotary worktable drives the support frame to rotate to the fixed frame, the feeding arc rod and the sliding clamping rod just send a guide ring to the through hole in the fixed frame. Subsequently, in cooperation with the lifting push block, the guide ring between the feeding arc rod and the sliding clamping rod is pushed downward to prevent the guide ring from shifting, ensuring the normal progress of subsequent welding work.

[0017] 4. During the rotation of the rotary worktable, the positioning cylinder is in a separated state from the guide ring. When the lifting frame descends and welds the guide ring and the basin frame, the pressure plate first spreads open the two sliding clamping blocks through the sliding support block. The two sliding clamping blocks adjust the position of the guide ring to make the guide ring coaxial with the positioning cylinder, thereby ensuring that the guide ring is coaxial with the basin frame. At the same time, it can also prevent the guide ring and the basin frame from shifting during the welding process. During welding, the rotary motor drives the guide ring and the basin frame to rotate uniformly through the positioning cylinder, and the welding time of the welding torch at the joint of the guide ring and the basin frame is the same, ensuring the welding effect.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: An automobile part welding and processing device, as Figures 1-9As shown in the figure, it includes a fixed bracket 1, a control motor 101, a rotating shaft 102, a bevel gear transmission group 103, a rotating workbench 104, a control cylinder 2, a lifting frame 201, a positioning component, an automatic material taking mechanism, and a welding mechanism. A control motor 101 is installed inside the fixed bracket 1. A rotating shaft 102 is rotatably connected inside the fixed bracket 1. The rotating shaft 102 is connected to the output shaft of the control motor 101 through the bevel gear transmission group 103. The control motor 101 drives the rotating shaft 102 to rotate through the bevel gear transmission group 103. A rotating workbench 104 is fixedly connected to the rotating shaft 102. A control cylinder 2 is installed inside the fixed bracket 1. A lifting frame 201 is slidably connected inside the fixed bracket 1. The telescopic rod of the control cylinder 2 is fixedly connected to the lifting frame 201. The control cylinder 2 pushes the lifting frame 201 to move up and down. A positioning component is installed on the rotating workbench 104. During the process of the lifting frame 201 descending, the automatic material taking mechanism automatically sends the basin frame into the positioning component. The welding mechanism is installed inside the lifting frame 201.

[0030] The control motor 101 is a stepping motor. Each time the stepping motor operates, it drives the rotating shaft 102 to rotate 90 degrees through the bevel gear transmission group 103, and then drives the rotating workbench 104 to rotate 90 degrees. Four groups of positioning components are installed on the rotating workbench 104. Each time the rotating workbench 104 rotates, a positioning component will move below the automatic material taking mechanism and the welding mechanism. Whenever the rotating workbench 104 stops rotating, the control cylinder 2 will push the lifting frame 201 to descend once. During the process of the lifting frame 201 descending, the automatic material taking mechanism sends the basin frame into the positioning component. After the positioning component moves away from the bottom of the automatic material taking mechanism, the operator sleeves the guide ring on the positioning component so that the bottom surface of the guide ring contacts the basin frame. When the rotating workbench 104 sends the positioning component with the basin frame and the guide ring below the welding mechanism, the welding mechanism welds the basin frame and the guide ring together. After welding is completed, the rotating workbench 104 rotates to an empty position, and the operator takes out the welded basin frame.

[0031] Embodiment 2: On the basis of Embodiment 1, as Figure 2 shown, the positioning component includes a support frame 105 and a positioning cylinder 106. Support frames 105 are evenly spaced and installed on the rotating workbench 104. A positioning cylinder 106 is rotatably connected to the support frame 105. The basin frame can just be sleeved outside the positioning cylinder 106 and rest on the support frame 105.

[0032] Each time the rotating workbench 104 rotates 90 degrees, when the support frame 105 rotates with the rotating workbench 104 to the bottom of the lifting frame 201, the control cylinder 2 pushes the lifting frame 201 to descend, and the automatic material taking mechanism descends accordingly. At this time, the basin frame inside the automatic material taking mechanism can just be sleeved outside the positioning cylinder 106. When placing the guide ring, the guide ring is also sleeved outside the positioning cylinder 106 to limit the positions of the basin frame and the guide ring to ensure the subsequent welding effect.

[0033] As Figure 2 , Figure 4 and Figure 5 shown, the automatic material taking mechanism includes a wedge-shaped push rod 1051, a material storage cylinder 202, a wedge-shaped stop 2021, a return spring 2022, a transmission rack 2023, a transmission gear 2024 and a sliding baffle 2025. The wedge-shaped push rod 1051 is fixedly connected to the support frame 105, and the material storage cylinder 202 is fixedly connected inside the lifting frame 202. The material storage cylinder 202 is used for storing basin frames. A wedge-shaped stop 2021 is slidably connected inside the material storage cylinder 202. The wedge-shaped stop 2021 supports the basin frames inside it from the bottom end of the material storage cylinder 202. The wedge-shaped stop 2021 and the material storage cylinder 202 are connected by a return spring 2022. One end of the return spring 2022 is fixed on the material storage cylinder 202, and the other end is fixed on the wedge-shaped stop 2021. A sliding baffle 2025 is slidably connected inside the material storage cylinder 202. The sliding baffle 2025 is located above the wedge-shaped stop 2021 on the same side. A transmission rack 2023 is fixedly connected to the bottom surface of the sliding baffle 2025, and a transmission rack 2023 is also fixedly connected to the top surface of the wedge-shaped stop 2021. A transmission gear 2024 is rotatably connected inside the material storage cylinder 202. The upper and lower ends of the transmission gear 2024 are respectively engaged with the transmission racks 2023 on the sliding baffle 2025 and the wedge-shaped stop 2021. Under the action of the transmission gear 2024 and the transmission rack 2023, the wedge-shaped stop 2021 and the sliding baffle 2025 move in opposite directions simultaneously.

[0034] Every time the rotary table 104 rotates 90 degrees, the control motor 101 will stall for a period of time. During this period, the control cylinder 2 is controlled to push the lifting frame 201 and the devices thereon to descend. During the descent of the storage cylinder 202, the wedge-shaped stop 2021 contacts the wedge-shaped push rod 1051. As the lifting frame 201 and the storage cylinder 202 continue to descend, the wedge-shaped stop 2021 is pushed to both sides by the wedge-shaped push rod 1051 and compresses the return spring 2022. And when the storage cylinder 202 descends to the lowest position, the basin frame in the storage cylinder 202 just sleeved outside the positioning cylinder 106. At this time, the wedge-shaped stop 2021 is fully opened by the wedge-shaped push rod 1051. The basin frame in the storage cylinder 202 slides down along the positioning cylinder 106 and lands on the support frame 105. When the two wedge-shaped stops 2021 move away from each other along the storage cylinder 202, under the action of the transmission rack 2023 and the transmission gear 2024, the two sliding baffles 2025 slide along the storage cylinder 202 and approach each other. When the wedge-shaped stop 2021 disengages from the basin frame at the lowest position in the storage cylinder 202, the sliding baffle 2025 has already supported under the second-to-last basin frame in the storage cylinder 202 to ensure that only one basin frame slides out of the storage cylinder 202 each time it descends. Subsequently, the control cylinder 2 drives the lifting frame 201 and the devices thereon to rise and reset. During the ascent of the storage cylinder 202 and the devices thereon, the wedge-shaped stop 2021 disengages from the wedge-shaped push rod 1051. Under the push of the return spring 2022, the two wedge-shaped stops 2021 slide along the storage cylinder 202 to reset and approach each other. Driven by the transmission rack 2023 and the transmission gear 2024, the two sliding baffles 2025 slide along the storage cylinder 202 and move away from each other. When the sliding baffle 2025 disengages from the basin frame, the wedge-shaped stop 2021 just blocks at the bottom of the storage cylinder 202, and the basin frame in the storage cylinder 202 slides down onto the wedge-shaped stop 2021.

[0035] As Figures 2-4 and Figure 9 shown, the welding mechanism includes an air cylinder 4, a welding torch 401, a fixed frame 402 and a tightening and rotating assembly. The air cylinder 4 is installed in the lifting frame 201. The bottom of the air cylinder 4 is fixedly connected with the fixed frame 402. The welding torch 401 is fixedly connected to the fixed frame 402. The air cylinder 4 and the welding torch 401 are connected by a trachea. When the lifting frame 201 descends, the tightening and rotating assembly tightens the guide ring outside the positioning cylinder 106.

[0036] When the rotary table 104 sends the support frame 105 and the positioning cylinder 106 below the welding torch 401, the control cylinder 2 is controlled to push the lifting frame 201 to descend again, and the air cylinder 4, the fixed frame 402 and the welding torch 401 descend accordingly. When the lifting frame 201 descends to the lowest position, the welding torch 401 just aligns with the position where the guide ring contacts the basin frame. At this time, the tightening and rotating assembly tightens the guide ring outside the positioning cylinder 106. First, the welding torch 401 is started to weld a point on the guide ring and the basin frame that is aligned with the welding torch 401 together. Subsequently, the tightening and rotating assembly is started. The tightening and rotating assembly drives the guide ring and the basin frame to rotate on the support frame 105 through the positioning cylinder 106. During the rotation of the positioning cylinder 106, the welding torch 401 continuously operates and welds the guide ring and the basin frame completely together. After the tightening and rotating assembly drives the positioning cylinder 106 to rotate one circle, it stops operating, and the welding torch 401 is turned off accordingly. Subsequently, the control cylinder 2 drives the lifting frame 201 to rise and reset again, and the tightening and rotating assembly is separated from contact with the guide ring.

[0037] As Figure 3 and Figure 9 shown, the tightening and rotating assembly includes a sliding support block 1061, a support spring 1062, a sliding tightening block 1063, a tension spring 1064, a rotary motor 107 and a pressure plate 403. A sliding support block 1061 is slidably connected inside the positioning cylinder 106. The sliding support block 1061 and the positioning cylinder 106 are connected by a support spring 1062. One end of the support spring 1062 is fixed on the positioning cylinder 106, and the other end is fixed on the sliding support block 1061. A sliding tightening block 1063 is slidably connected inside the positioning cylinder 106. The bottom end of the sliding support block 1061 is triangular, and the inclined surface at the bottom end of the sliding support block 1061 contacts the sliding tightening block 1063. The two sliding tightening blocks 1063 are connected by a tension spring 1064. The two ends of the tension spring 1064 are respectively fixed on the sliding tightening blocks 1063 on the corresponding side. Through holes are formed in the inner wall of the positioning cylinder 106 corresponding to the sliding tightening blocks 1063. The sliding tightening blocks 1063 can slide into the through holes on the inner wall of the positioning cylinder 106 and tighten the guide ring. A rotary motor 107 is installed inside the support frame 105. The output shaft of the rotary motor 107 is connected to the positioning cylinder 106. The pressure plate 403 is fixedly connected to the fixed frame 402. When the lifting frame 201 descends, the pressure plate 403 contacts the sliding support block 1061 and pushes it to slide into the positioning cylinder 106.

[0038] When the lifting frame 201 and the device thereon descend, the pressure plate 403 descends accordingly and pushes the sliding support block 1061 into the positioning cylinder 106. When the sliding support block 1061 descends along the positioning cylinder 106, it compresses the support spring 1062. When the sliding support block 1061 descends, it pushes the two sliding tightening blocks 1063 to both sides and stretches the tension spring 1064. After being stretched open by the sliding support block 1061, the two sliding tightening blocks 1063 slide into the through hole of the positioning cylinder 106. When the pressure plate 403 descends to the lowest point, the sliding support block 1061 fully stretches the two sliding tightening blocks 1063. The two sliding tightening blocks 1063 just press on the inner wall of the guide ring, and because the two sliding tightening blocks 1063 slide outward along the positioning cylinder 106 synchronously, the sliding tightening blocks 1063 Block 1063 can also adjust the guide ring to a position coaxial with the positioning cylinder 106 to ensure the welding effect. When the guide ring and the basin frame are connected at a point opposite to the welding gun 401 and are welded together, the rotating motor 107 is started. The rotating motor 107 drives its internal device to rotate through the positioning cylinder 106. When the positioning cylinder 106 rotates, the two sliding support blocks 1063 drive the basin frame to rotate through the guide ring. During the rotation, the welding gun 401 welds the guide ring and the basin frame together. After welding is completed, the pressure plate 403 rises and resets, and the support spring 1062 pushes the sliding support block 1061 to rise and reset. The two sliding support blocks 1063 move closer to each other and reset under the pull of the tension spring 1064 and fit together with the sliding support block 1061 again.

[0039] Example 3: Based on Example 2, Figure 2 and Figure 4 As shown, it also includes a flip gear 1052 and a lifting rack 204. The lifting rack 204 is fixedly connected to the lifting frame 201, and the flip gear 1052 is fixedly connected to the support frame 105. After the rotating workbench 104 drives the support frame 105 to rotate below the lifting rack 204, when the lifting frame 201 descends, the lifting rack 204 drives the support frame 105 to rotate around the rotating workbench 104 through the flip gear 1052. There is a large rotational resistance between the support frame 105 and the rotating workbench 104, and the support frame 105 will not rotate when there is no external force.

[0040] After the basin holder and the guide ring on the support frame 105 are welded together, the rotary table 104 drives the support frame 105 to rotate 90 degrees again. Then, the lifting frame 201 descends again and drives the lifting rack 204 to descend. When the lifting rack 204 descends, it drives the support frame 105 to rotate through the flipping gear 1052. When the lifting frame 201 descends to the lowest position, the lifting rack 204 just drives the flipping gear 1052 and the support frame 105 to rotate 180 degrees. The basin holder and the guide ring welded together on the support frame 105 slide down from outside the positioning cylinder 106. When the lifting frame 201 rises and resets, the lifting rack 204 drives the support frame 105 to rotate 180 degrees and reset through the flipping gear 1052 again, realizing the function of automatically sending out the welded basin holder.

[0041] As Figures 6-8 shown, it further includes a side support 3, a rotating rod 301, a transmission belt 302, a storage cylinder 303, a fixed frame 304, a limit ring 3041 and a feeding arc rod 305. A side support 3 is fixedly connected to the inner bottom plate of the fixed support 1. A rotating rod 301 is rotatably connected inside the side support 3. The rotating shaft 102 and the rotating rod 301 are connected by a transmission belt 302. The rotating shaft 102 drives the rotating rod 301 to rotate through the transmission belt 302. A fixed frame 304 is fixedly connected inside the side support 3. A limit ring 3041 is fixedly connected inside the fixed frame 304. The guide ring can just be placed between the inner wall of the fixed frame 304 and the outer wall of the limit ring 3041. A storage cylinder 303 is fixedly connected inside the side support 3. The storage cylinder 303 is used to store the guide rings. Feeding arc rods 305 are evenly and spacedly fixedly connected to the rotating rod 301. The number of the feeding arc rods 305 is equivalent to the number of the support frames 105. A through hole is opened on the inner bottom surface of the fixed frame 304. Each time the rotating shaft 102 rotates, a support frame 105 will be moved to the position below the through hole opened on the inner bottom surface of the fixed frame 304. At this time, the feeding arc rod 305 pushes a guide ring to move to the through hole on the inner bottom surface of the fixed frame 304. The guide ring drops downward from inside the fixed frame 304 and is sleeved outside the positioning cylinder 106 on the support frame 105.

[0042] After the basin stand is placed outside the positioning cylinder 106 on the support frame 105, the rotary workbench 104 drives the support frame 105 to rotate to the bottom of the fixed frame 304. At this time, the positioning cylinder 106 is located at the through hole on the bottom surface of the fixed frame 304. When the control motor 101 drives the rotating shaft 102 to rotate through the bevel gear transmission group 103, the rotating shaft 102 drives the rotating rod 301 to rotate through the transmission belt 302. When the feeding arc rod 305 rotates from the bottom of the storage cylinder 303, a guiding ring will be pushed out. Subsequently, the guiding ring in the storage cylinder 303 slides downward, and the bottom surface of the lowermost guiding ring contacts the fixed frame 304, and the distance between the bottom surface of the storage cylinder 303 and the fixed frame 304 is slightly higher than the height of the guiding ring. When the rotating rod 301 rotates, the feeding arc rod 305 pushes the guiding ring to slide between the inner wall of the fixed frame 304 and the limiting ring 3041. When the guiding ring is pushed to the through hole on the fixed frame 304, the guiding ring drops downward along the through hole and sleeves outside the positioning cylinder 106.

[0043] As Figure 4 and Figure 8 shown, it further includes a lifting push block 203, a sliding clamping rod 306 and a clamping spring 3061. The lifting push block 203 is fixedly connected to the lifting frame 201. The sliding clamping rod 306 is slidably connected in the fixed frame 304. The sliding clamping rod 306 is connected to the fixed frame 304 through the clamping spring 3061. One end of the clamping spring 3061 is fixedly connected to the fixed frame 304, and the other end is fixed to the sliding clamping rod 306. The sliding clamping rod 306 and the feeding arc rod 305 jointly clamp the guiding ring. The lifting push block 203 descends to push the guiding ring between the sliding clamping rod 306 and the feeding arc rod 305 downward, so that the guiding ring drops vertically and sleeves outside the positioning cylinder 106.

[0044] During the process that the feeding arc rod 305 rotates with the rotating rod 301 and pushes the guiding ring to slide in the fixed frame 304, the guiding ring contacts the sliding clamping rod 306. As the feeding arc rod 305 continues to move, the feeding arc rod 305 pushes the sliding clamping rod 306 to slide along the fixed frame 304 and compress the clamping spring 3061 through the guiding ring. At this time, under the push of the clamping spring 3061, the sliding clamping rod 306 and the feeding arc rod 305 clamp the guiding ring. When the guiding ring is pushed to the through hole in the fixed frame 304, the guiding ring is clamped and cannot drop downward. The lifting frame 201 descends and pushes the guiding ring downward from between the sliding clamping rod 306 and the feeding arc rod 305 through the lifting push block 203, so that the guiding ring drops vertically, so as to prevent the guiding ring from being skewed during the descending process and unable to sleeve outside the positioning cylinder 106, realizing the function of automatically placing the guiding ring.

[0045] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
