Description

Technical Field

[0001] The 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 audio signal device. During the driving process of the car, the driver sends out necessary audio signals according to needs and regulations to warn pedestrians and attract the attention of other vehicles to ensure traffic safety. The horn includes a basin frame, T iron, magnet, guide ring and other structures. The basin frame plays the role of supporting and fixing other parts. In the process of producing the horn, some parts need to be welded together with the basin frame.

[0003] Most of the existing welding tables are composed of a placement table, a welding gun, a fixing plate and a mounting groove. When assembling and welding the loudspeaker, the basin frame is first placed in the mounting groove 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. Then a welding gun is used to weld the guide ring and the basin frame together. 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 will cause the welding position of the welding gun to shift, affecting the welding effect. In addition, it is difficult to make the basin frame rotate at a uniform speed when manually rotating the basin frame, which makes the welding at the connection between the guide ring and the basin frame uneven, thereby affecting the product quality.

[0014] The beneficial effects of the present invention are as follows: 1. The device realizes raw material positioning and placement, raw material transportation, rotary welding and other processes through automated assembly line production. Four groups of support frames are arranged on the rotary workbench to form a four-station processing platform. Multiple processes are carried out simultaneously, saving labor costs and improving work efficiency.

The automatic material picking 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. In the process of taking the basin rack, the sliding baffles and the wedge-shaped baffles are arranged alternately, and under the action of the transmission gear and the transmission rack, the sliding baffles and the wedge-shaped baffles move in different directions to support basin racks of different heights, so as to ensure that only one basin rack is placed on the support frame at a time.

[0017] 4. During the rotation of the rotary worktable, the positioning cylinder and the guide ring are in a separated state. When the lifting frame descends and welds the guide ring and the basin frame, the pressure plate first opens the two sliding support blocks through the sliding support block. The two sliding support 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 avoid the deviation of the guide ring and the basin frame during welding. During welding, the rotating motor drives the guide ring and the basin frame to rotate at a uniform speed through the positioning cylinder. The welding gun has the same welding time on the joint of the guide ring and the basin frame to ensure the welding effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] 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.

[0029] Embodiment 1: A welding processing device for automobile parts, such as Figure 1-Figure 9As shown, it includes a fixed bracket 1, a control motor 101, a rotating shaft 102, a bevel gear transmission group 103, a rotating worktable 104, a control cylinder 2, a lifting frame 201, a positioning component, an automatic material picking mechanism and a welding mechanism. The control motor 101 is installed in the fixed bracket 1, and the rotating shaft 102 is rotatably connected in 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. The rotating worktable 104 is fixedly connected to the rotating shaft 102. The control cylinder 2 is installed in the fixed bracket 1. The lifting frame 201 is slidably connected in 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. The positioning component is installed on the rotating worktable 104. During the descent of the lifting frame 201, the automatic material picking mechanism automatically sends the basin frame into the positioning component. The welding mechanism is installed in the lifting frame 201.

[0030] The control motor 101 is a stepper motor. Each time the stepper motor runs, it will drive the rotating shaft 102 to rotate 90 degrees through the bevel gear transmission group 103, and then drive the rotary table 104 to rotate 90 degrees. Four sets of positioning components are installed on the rotary table 104. Each time the rotary table 104 rotates, the positioning components will move to the bottom of the automatic material picking mechanism and the welding mechanism. Whenever the rotary table 104 stops rotating, the control cylinder 2 will push the lifting frame 201 to descend once. During the descent of the lifting frame 201, the automatic material picking mechanism sends the basin frame to the positioning component. When the positioning component is removed from the bottom of the automatic material picking mechanism, the operator sets the guide ring in the positioning component so that the bottom surface of the guide ring contacts the basin frame. When the rotary table 104 sends the positioning component with the basin frame and the guide ring to the bottom of the welding mechanism, the welding mechanism welds the basin frame and the guide ring together. After welding is completed, the rotary table 104 rotates to an empty space, and the operator takes out the welded basin frame.

[0031] Embodiment 2: Based on embodiment 1, Figure 2 As shown, the positioning assembly includes a support frame 105 and a positioning cylinder 106. The support frames 105 are evenly installed on the rotating workbench 104. The positioning cylinder 106 is rotatably connected to the support frame 105. The basin frame can just be put outside the positioning cylinder 106 and fall on the support frame 105.

[0032] Each time the rotating worktable 104 rotates 90 degrees, the support frame 105 rotates with the rotating worktable 104 to the bottom of the lifting frame 201, and the control cylinder 2 pushes the lifting frame 201 to descend, and the automatic material picking mechanism descends accordingly. At this time, the basin frame in the automatic material picking mechanism can be just 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 position of the basin frame and the guide ring to ensure the subsequent welding effect.

[0033] like Figure 2 , Figure 4 and Figure 5 As shown, the automatic material taking mechanism includes a wedge-shaped push rod 1051, a material storage barrel 202, a wedge-shaped baffle 2021, a return spring 2022, a transmission rack 2023, a transmission gear 2024 and a sliding baffle 2025. The support frame 105 is fixedly connected with the wedge-shaped push rod 1051, and the lifting frame 201 is fixedly connected with the material storage barrel 202. The material storage barrel 202 is used to store the basin rack. The material storage barrel 202 is slidably connected with the wedge-shaped baffle 2021. The wedge-shaped baffle 2021 supports the basin rack inside the material storage barrel 202 from the bottom end thereof. The wedge-shaped baffle 2021 and the material storage barrel 202 are connected by a return spring 2022. One end of the return spring 2022 is fixed on the material storage barrel 202, and the other end is fixed on the material storage barrel 202. The end is fixed on the wedge-shaped baffle 2021, and a sliding baffle 2025 is slidably connected in the storage barrel 202, and the sliding baffle 2025 is located above the wedge-shaped baffle 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 fixedly connected to the top surface of the wedge-shaped baffle 2021. A transmission gear 2024 is rotatably connected in the storage barrel 202, and the upper and lower ends of the transmission gear 2024 are respectively meshed with the sliding baffle 2025 and the transmission rack 2023 on the wedge-shaped baffle 2021. Under the action of the transmission gear 2024 and the transmission rack 2023, the wedge-shaped baffle 2021 and the sliding baffle 2025 move in opposite directions at the same time.

[0034] Every time the rotating table 104 rotates 90 degrees, the control motor 101 will stop for a period of time. During this period, the control cylinder 2 pushes the lifting frame 201 and the device on it to descend. During the descent of the storage barrel 202, the wedge-shaped blocking frame 2021 contacts the wedge-shaped push rod 1051. As the lifting frame 201 and the storage barrel 202 continue to descend, the wedge-shaped blocking frame 2021 is pushed to both sides by the wedge-shaped push rod 1051 and compresses the return spring 2022, and the storage barrel 202 is moved downward. When the material storage barrel 202 is lowered to the lowest point, the basin frame in the material storage barrel 202 is just set outside the positioning barrel 106. At this time, the wedge-shaped blocking frame 2021 is fully opened by the wedge-shaped push rod 1051, and the basin frame in the material storage barrel 202 slides down along the positioning barrel 106 and falls onto the support frame 105. When the two wedge-shaped blocking frames 2021 move away from each other along the material storage barrel 202, under the action of the transmission rack 2023 and the transmission gear 2024, the two sliding baffles 2025 slide along the material storage barrel 202 and move toward each other. When the wedge-shaped retaining frame 2021 is out of contact with the lowest basin frame in the storage barrel 202, the sliding baffle 2025 has been supported under the second-to-last basin frame in the storage barrel 202 to ensure that only one basin frame will slide down from the storage barrel 202 each time it descends. Then the control cylinder 2 drives the lifting frame 201 and the device thereon to rise and reset. During the process of the storage barrel 202 and the device thereon rising, the wedge-shaped retaining frame 2021 is out of contact with the wedge-shaped push rod 1051. Under the push of the reset spring 2022, the two wedge-shaped baffles 2021 slide and reset along the storage barrel 202 and move closer to each other. Driven by the transmission rack 2023 and the transmission gear 2024, the two sliding baffles 2025 slide along the storage barrel 202 and move away from each other. When the sliding baffles 2025 are out of contact with the basin frame, the wedge-shaped baffle 2021 just blocks the bottom of the storage barrel 202, and the basin frame in the storage barrel 202 slides down onto the wedge-shaped baffle 2021.

[0035] like Figure 2-Figure 4 and Fig. 9 As shown, the welding mechanism includes a gas cylinder 4, a welding gun 401, a fixing frame 402 and a tightening rotating assembly. The gas cylinder 4 is installed in the lifting frame 201, the fixing frame 402 is fixedly connected to the bottom of the gas cylinder 4, the welding gun 401 is fixedly connected to the fixing frame 402, and the gas cylinder 4 and the welding gun 401 are connected through an air guide tube. When the lifting frame 201 descends, the tightening rotating assembly tightens the guide ring outside the positioning cylinder 106.

[0036] When the rotating table 104 sends the supporting frame 105 and the positioning cylinder 106 to the bottom of the welding gun 401, the control cylinder 2 pushes the lifting frame 201 to descend again, and the cylinder 4, the fixing frame 402 and the welding gun 401 descend accordingly. When the lifting frame 201 descends to the lowest point, the welding gun 401 is just aligned with the contact position of the guide ring and the basin frame. At this time, the tightening rotating assembly tightens the guide ring outside the positioning cylinder 106, first starts the welding gun 401, and welds the guide ring to a point on the basin frame that is aligned with the welding gun 401. Then, the tightening rotating assembly is started. The tightening rotating assembly drives the guide ring and the basin frame to rotate on the supporting frame 105 through the positioning cylinder 106. During the rotation of the positioning cylinder 106, the welding gun 401 continues to run and completely welds the guide ring and the basin frame together. The tightening rotating assembly drives the positioning cylinder 106 to rotate one circle and then stops running. The welding gun 401 is closed accordingly. Then, the control cylinder 2 drives the lifting frame 201 to rise and reset again, and the tightening rotating assembly is out of contact with the guide ring.

[0037] like Figure 3 and Fig. 9 As shown, the tightening rotation assembly includes a sliding support block 1061, a support spring 1062, a sliding tightening block 1063, a tension spring 1064, a rotating motor 107 and a pressure plate 403. The sliding support block 1061 is slidably connected in the positioning cylinder 106. The sliding support block 1061 and the positioning cylinder 106 are connected through the support spring 1062. One end of the support spring 1062 is fixed to the positioning cylinder 106, and the other end is fixed to the sliding support block 1061. The sliding tightening block 1063 is slidably connected in the positioning cylinder 106. The bottom end of the sliding support block 1061 is triangular, and the inclined surface of the bottom end of the sliding support block 1061 is connected to the sliding tightening block 1063. The two sliding tightening blocks 1063 are connected by a tension spring 1064, and the two ends of the tension spring 1064 are respectively fixed on the sliding tightening block 1063 on the corresponding side. A through hole is opened on the inner wall of the positioning cylinder 106 corresponding to the position of the sliding tightening block 1063. The sliding tightening block 1063 can slide into the through hole on the inner wall of the positioning cylinder 106 and tighten the guide ring. A rotating motor 107 is installed in the support frame 105, and the output shaft of the rotating motor 107 is connected to the positioning cylinder 106. A pressure plate 403 is fixed 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 the two sliding tightening blocks 1063 are stretched open by the sliding support block 1061, they 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 completely stretches the two sliding tightening blocks 1063. The two sliding tightening blocks 1063 just press on the inner wall of the guide ring. Moreover, since 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, start the rotating motor 107. 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, 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] Embodiment 3: Based on embodiment 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 worktable 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 worktable 104 through the flip gear 1052. There is a large rotation resistance between the support frame 105 and the rotating worktable 104, and the support frame 105 will not rotate without the influence of external force.

[0040] After the basin frame and the guide ring on the support frame 105 are welded together, the rotating workbench 104 drives the support frame 105 to rotate 90 degrees again, and 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 flip gear 1052. When the lifting frame 201 descends to the lowest point, the lifting rack 204 just drives the flip gear 1052 and the support frame 105 to rotate 180 degrees. The basin frame and the guide ring welded together on the support frame 105 slide downward from the outside of 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 resets again through the flip gear 1052, thereby realizing the function of automatically sending out the welded basin frame.

[0041] like Figure 6-Figure 8 As shown, it also includes a side bracket 3, a rotating rod 301, a transmission belt 302, a material storage barrel 303, a fixed frame 304, a limiting ring 3041 and a feeding arc rod 305. The side bracket 3 is fixedly connected to the inner bottom plate of the fixed bracket 1, and the rotating rod 301 is rotatably connected inside the side bracket 3. The rotating shaft 102 and the rotating rod 301 are connected through the transmission belt 302. The rotating shaft 102 drives the rotating rod 301 to rotate through the transmission belt 302. The fixed frame 304 is fixedly connected inside the side bracket 3, and the limiting ring 3041 is fixedly connected inside the fixed frame 304. The guide ring can just be placed on the inner wall of the fixed frame 304 and the outer wall of the limiting ring 3041 A material storage barrel 303 is fixedly connected to the side bracket 3, and the material storage barrel 303 is used to store the guide ring. Feeding arc rods 305 are evenly spaced and fixedly connected to the rotating rod 301. The number of feeding arc rods 305 is equivalent to the number of support frames 105. A through hole is opened on the inner bottom surface of the fixed frame 304. Each rotation of the rotating shaft 102 will move a support frame 105 to the bottom of 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, and the guide ring falls downward from the fixed frame 304 and is sleeved on the outside of the positioning barrel 106 on the support frame 105.

[0042] After the basin frame is placed outside the positioning cylinder 106 on the support frame 105, the rotating 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 barrel 303, a guide ring will be pushed out. , then the guide ring in the storage barrel 303 slides downward, the bottom surface of the lowest guide ring contacts the fixed frame 304, and the distance between the bottom surface of the storage barrel 303 and the fixed frame 304 is slightly higher than the height of the guide ring. When the rotating rod 301 rotates, the feeding arc rod 305 pushes the guide ring to slide between the inner wall of the fixed frame 304 and the limit ring 3041. When the guide ring is pushed to the through hole on the fixed frame 304, the guide ring falls downward along the through hole and is sleeved on the outside of the positioning barrel 106.

[0043] like Figure 4 and Figure 8 As shown, it also 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, and a sliding clamping rod 306 is slidably connected in the fixed frame 304. The sliding clamping rod 306 and the fixed frame 304 are connected 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.
