Description

Technical Field

[0001] This invention relates to the field of vehicle frame welding technology, and in particular to a vehicle frame flipping welding device. Background Technology

[0002] The car frame is the main body of the car, and all other components are mounted on the frame. The car frame is made of multiple aluminum plates welded together. Due to the large size of the car structure and the large number of parts that need to be welded, which are located in different places, the welding process is quite complicated.

[0003] There are existing devices that clamp and flip the frame to facilitate welding in some complex locations.

[0004] However, during vehicle production, the vehicle is moved using skids and rollers. Flipping the frame requires lifting it up and then flipping it again. After welding, it needs to be reinstalled on the skids. During this process, the frame is prone to misalignment and damage, resulting in a complex and inefficient flipping process. Summary of the Invention

[0005] The purpose of this invention is to provide a chassis flipping and welding device, which aims to solve the problems of complex flipping processes and low efficiency of existing flipping devices.

[0006] To achieve the above objectives, the present invention provides a vehicle frame flipping and welding device, comprising a base, two rotating frames, two rotating rings, a rotating seat, a roller bed, two first rotary motors, two first winches, two first steel cables, a fixing assembly, a second rotary motor, a second winch, and a second steel cable. The two rotating frames are fixed to both sides of the base; the two rotating rings are disposed within the two rotating frames; the rotating seat is fixed between the two rotating rings; the roller bed is fixed to the rotating seat; the two first rotary motors are fixed to both sides of the base near the rotating seat; the two first winches are fixed to the output ends of the two first rotary motors; the two first steel cables are fixedly connected to the two first winches and to the rotating seat; the fixing assembly is disposed on the rotating seat; the second rotary motor is fixed to the base; the second winch is fixed to the output end of the second rotary motor; the second steel cable is fixedly connected to the second winch and to the rotating seat.

The multiple limiting rods are arranged and fixed on the inner side of the two rotating rings; the multiple limiting wheels are rotatably mounted on the multiple limiting rods; and the multiple limiting blocks are fixed on the multiple limiting rods and located on the outer side of the limiting wheels.

[0008] The fixing assembly includes a top frame, two first hydraulic rods, and two support plates. The top frame is fixed to the rotating seat; the two first hydraulic rods are fixed below the top frame; and the two support plates are fixed to the output ends of the two first hydraulic rods.

[0009] The fixing component also includes two rubber pads, which are fixed below the two support plates.

[0010] The fixing assembly further includes two fixing motors, two rotating shafts, and two fixing forks. The two fixing motors are fixed on both sides of the rotating base; the two rotating shafts are fixed to the output ends of the two fixing motors; and the two fixing forks are fixed on the two rotating shafts.

[0011] The vehicle frame flipping welding device further includes a welding table and a sliding table. The welding table is fixed to one side of the base, and the sliding table is slidably disposed in the welding table.

[0012] The frame flipping welding device also includes a guardrail, which is fixed on the sliding table.

[0013] This invention discloses a vehicle frame flipping and welding device. A base provides support for the entire device. Two rotating frames are fixed to both sides of the base and used to install and restrict two rotating rings. A rotating seat is fixedly connected to both rotating rings and located between them, used to mount a roller bed. The roller bed is used to transport and support a skid under the vehicle frame. Two first rotary motors drive a first winch to rotate, thereby driving two first steel cables to wind up and pull the rotating seat to rotate. A fixing assembly is used to fix the vehicle frame. A second motor drives a second winch and controls a second steel cable. The second steel cable is located on the side of the rotating seat away from the first steel cable. When the first rotary motor starts, the second rotary motor starts synchronously to release the second steel cable. During reset, the second rotary motor acts as a guide, allowing the rotating seat to rotate and reset along its original trajectory. The device provided by this invention fixes the vehicle frame to the roller bed through the fixing assembly, driving it to flip synchronously. After flipping and welding, it can achieve rapid reset and transport the vehicle frame to the next process, thus solving the problems of complex flipping processes and low efficiency in existing flipping devices.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] For the first embodiment, please refer to... Figures 1-3 , Figure 1 This is a schematic diagram of the structure of a frame flipping and welding device according to the first embodiment of the present invention; Figure 2 This is a side view of a frame flipping and welding device according to the first embodiment of the present invention; Figure 3 This is a top view of a chassis flipping and welding device according to the first embodiment of the present invention.

[0024] This invention provides a vehicle frame flipping and welding device, comprising a base 101, two rotating frames 102, two rotating rings 103, a rotating seat 104, a roller bed 105, two first rotary motors 106, two first winches 107, two first steel cables 108, a fixing assembly, a second rotary motor 109, a second winch 110, a second steel cable 111, multiple limiting rods 112, multiple limiting wheels 113, and multiple limiting blocks 114. The fixing assembly includes a top frame 115, two first hydraulic rods 116, two support plates 117, two rubber pads 118, two fixing motors 119, two rotating shafts 120, and two fixing forks 121.

[0025] The aforementioned solution solves the problems of complex and inefficient flipping processes in existing flipping devices. It is understood that the aforementioned solution can fix the frame on the roller bed 105 through the fixing component, drive it to flip synchronously, and after flipping and welding, it can be quickly reset and transported to the next process.

[0026] In this embodiment, two rotating frames 102 are fixed on both sides of the base 101; two rotating rings 103 are disposed in the two rotating frames 102; a rotating seat 104 is fixed between the two rotating rings 103; a roller bed 105 is fixed on the rotating seat 104; two first rotary motors 106 are fixed on both sides of the base 101 near the rotating seat 104; two first winches 107 are fixed at the output ends of the two first rotary motors 106; two first steel cables 108 and two first winches are also present. 107 is fixedly connected and fixedly connected to the rotating base 104; the fixing assembly is disposed on the rotating base 104; the second rotary motor 109 is fixed to the base 101; the second winch 110 is fixed to the output end of the second rotary motor 109; the second steel cable 111 and the second winch 110 are fixedly connected and fixedly connected to the rotating base 104; the base 101 provides support for the entire device, and the two rotating frames 102 are fixed on both sides of the base 101 for mounting and limiting the two rotating rings 103. The rotating base 104 is fixedly connected to both of the two rotating rings 103, located between them, and is used to mount the roller bed 105. The roller bed 105 is used to transport and support the skid under the frame. The two first rotary motors 106 are used to drive the first winch 107 to rotate, thereby driving the two first steel cables 108 to wind up and pull the rotating base 104 to rotate. The fixing assembly is used to fix the frame. The second motor is used to drive the second winch 110 and control the second steel cable 111. The second steel cable 111 is located on the rotating base 104. On the side away from the first steel cable 108, when the first rotary motor 106 starts, the second rotary motor 109 starts synchronously to release the second steel cable 111. During reset, the second rotary motor 109 acts as a guide, allowing the rotating seat 104 to rotate and reset along its original trajectory. The device provided by the present invention fixes the frame on the roller bed 105 through the fixing component, driving it to rotate synchronously. After rotation and welding, it can achieve rapid reset and transport the frame to the next process, thereby solving the problem of complex rotation process and low efficiency of existing rotation devices.

[0027] The plurality of limiting rods 112 are arranged and fixed on the inner sides of the two rotating rings 103; the plurality of limiting wheels 113 are rotatably mounted on the plurality of limiting rods 112; the plurality of limiting blocks 114 are fixed on the plurality of limiting rods 112 and located on the outer side of the limiting wheels 113; the plurality of limiting rods 112 are used to mount the plurality of limiting wheels 113, the limiting wheels 113 are used to restrict the first steel cable 108, causing it to pull the rotating seat 104 along the rotating ring 103, and the rotating seat 104 rotates along with it when it is wound up; the limiting blocks 114 are used to close the outer side of the limiting wheels 113 to prevent the first steel cable 108 from slipping.

[0028] Secondly, the top frame 115 is fixed on the rotating seat 104; the two first hydraulic rods 116 are fixed below the top frame 115; the two support plates 117 are fixed at the output ends of the two first hydraulic rods 116; after the first hydraulic rods 116 extend, they drive the support plates 117 to extend, and after the support plates 117 extend, they abut against the upper edge of the frame. With the cooperation of the sliding skid under the frame, they will not fall off even if they are flipped.

[0029] Furthermore, the two rubber pads 118 are fixed below the two support plates 117; the two rubber pads 118 are used to protect the upper edge of the frame and prevent it from directly contacting the support plates 117, thus avoiding excessive force and deformation.

[0030] Finally, the two fixed motors 119 are fixed on both sides of the rotating seat 104; the two rotating shafts 120 are fixed on the output ends of the two fixed motors 119; the two fixed forks 121 are fixed on the two rotating shafts 120; the fixed motors 119 are used to drive the rotating shafts 120 to rotate, thereby controlling the position of the fixed forks 121. When the fixed forks 121 rotate to one side of the rotating seat 104, the slide can enter the roller bed 105. After the slide stops, the fixed motors 119 are started to rotate the fixed forks 121 out. The fixed forks 121 restrict the slide. When flipping, they can prevent the slide from moving and also share part of the force on the support plate 117, reducing the pressure received on the upper edge of the frame.

[0031] During use, the base 101 provides support for the entire device. Two rotating frames 102 are fixed to both sides of the base 101 and are used to install and restrict the two rotating rings 103. The rotating seat 104 is fixedly connected to both rotating rings 103 and located between them, used to install the roller bed 105. The roller bed 105 is used to transport and support the skids under the frame. Two first rotary motors 106 drive the first winch 107 to rotate, thereby driving the two first steel cables 108 to wind up and pull the rotating seat 104 to rotate. The fixing assembly is used to secure the frame. Fixed, the second motor drives the second winch 110 and controls the second steel cable 111. The second steel cable 111 is located on the side of the rotating seat 104 away from the first steel cable 108. When the first rotating motor 106 starts, the second rotating motor 109 starts synchronously to release the second steel cable 111. During reset, the second rotating motor 109 acts as a guide, allowing the rotating seat 104 to rotate and reset along its original trajectory. Multiple limiting rods 112 are used to install multiple limiting wheels 113. The limiting wheels 113 restrict the first steel cable 108, causing it to move along... The rotating ring 103 pulls the rotating seat 104, and the rotating seat 104 rotates along with it when it is wound up; after the first hydraulic rod 116 extends, it drives the support plate 117 to extend. After the support plate 117 extends, it abuts against the upper edge of the frame. With the cooperation of the sliding skid under the frame, it will not fall off even if it is flipped; the two rubber pads 118 are used to protect the upper edge of the frame and prevent it from directly contacting the support plate 117 and deforming due to excessive force; the fixed motor 119 is used to drive the rotating shaft 120 to rotate, thereby controlling the position of the fixed fork 121. The fixed fork 121 rotates to the position of the rotating shaft 120. When the swivel is on one side of the rotary table 104, the slide can enter the roller bed 105. After the slide stops, the fixed motor 119 is started to rotate the fixed fork 121 out. The fixed fork 121 restricts the slide. During the flipping, it can prevent the slide from moving and also share part of the force on the support plate 117, reducing the pressure on the upper edge of the frame. The device provided by the present invention fixes the frame on the roller bed 105 through the fixed component and drives it to flip synchronously. After the flipping and welding, it can achieve rapid reset and transport the frame to the next process, thereby solving the problem of complex flipping process and low efficiency of the existing flipping device.

[0039] Two fixing blocks 305 are fixed on both sides of the roller bed 105; two safety rods 304 are fixed on the two rotating frames 102; the two safety rods 304 are located on the side of the rotating frame 102 near the first rotary motor 106, and are used to support the fixing blocks 305, limit the maximum rotation angle of the roller bed 105, and temporarily support the roller bed 105 when the second rotary motor 109 fails, so as to prevent it from falling to the side and causing damage.
