Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0018] Example 1: Please refer to Figures 1 to 6 : This utility model discloses a turning machine for vehicle frame welding, including a slide rail frame 1, an upper turning frame 2, and a front transfer frame 3. A front slide rail 101 is fixedly connected to the front side of the slide rail frame 1. A horizontal telescopic cylinder 102 is fixedly connected to the middle of the slide rail frame 1. The horizontal telescopic cylinder 102 has a cylinder diameter of 100mm, a stroke of 500mm, and a working pressure of 16MPa. The upper turning frame 2 is slidably connected to the upper part of the slide rail frame 1. A vertical telescopic cylinder 201 is fixedly connected to the lower part of the upper turning frame 2. The vertical telescopic cylinder 201 has a cylinder diameter of 80mm and a stroke of 300mm. The telescopic rod of the vertical telescopic cylinder 201 and the turning... The rotating module 202 is fixedly connected. The motor power of the rotating module 202 is 5.5kW, the rotating angle is 0-360°, and the speed is 10r / min. The rotating shaft driven by the motor in the middle of the rotating module 202 is fixedly connected to the lower fixed clamp 203. The upper fixed clamp 205 is vertically slidably connected to the upper part of the lower fixed clamp 203. The middle telescopic cylinders 204 are fixedly connected to both sides of the lower fixed clamp 203. The rotating module 202 and the upper rotating frame 2 are vertically slidably connected. The telescopic rod of the middle telescopic cylinder 204 is fixedly connected to the upper fixed clamp 205. The lower fixed clamp 203 and the upper fixed clamp 205 clamp within a certain range. The circumference is 500-1500mm, the clamping force of the middle telescopic cylinder 204 is ≥50kN, and the clamping surface is made of rubber. The middle telescopic cylinder 204 drives the upper fixed clamp 205 to move down and approach the frame. The lower fixed clamp 203 and the upper fixed clamp 205 clamp the frame. The flipping module 202 drives the lower fixed clamp 203 and the upper fixed clamp 205 to flip the frame 360 degrees. A front transfer frame 3 is set on the front side of the upper flipping frame 2. The top of the front transfer frame 3 is fixedly connected to the upper telescopic cylinder 301. The upper end of the telescopic rod of the upper telescopic cylinder 301 is fixedly connected to the upper bracket 302. The upper motor-driven transmission shaft of the bracket 302 is connected to the upper conveyor belt 303 with the tensioning rollers. The rotating shaft of the flipping module 202 is supported by the self-aligning roller bearing, with an output torque of 500 Nm. It is equipped with a torque sensor and an overload protection threshold of 800 N·m. The front transfer frame 3 is driven by a Y132M-4 motor with four moving wheels equipped with electromagnetic brakes. The upper conveyor belt 303 is 1200 mm wide and has a conveying speed of 1 m / s. The front slide rail 101 and the front transfer frame 3 are both located in front of the lower fixed clamp 203. The transfer of the bracket is carried out between the lower fixed clamp 203 and the front transfer frame 3.
[0019] In this embodiment, the telescopic rod of the horizontal telescopic cylinder 102 is fixedly connected to the upper tilting frame 2. The horizontal telescopic cylinder 102 drives the upper tilting frame 2 to slide horizontally along the guide rail of the slide rail frame 1. The front slide rail 101 and the front transfer frame 3 are slidably connected. The front transfer frame 3 is equipped with a motor and a drive wheel to move horizontally along the front slide rail 101. This avoids the existing tilting machine being located at both ends of the frame, which requires auxiliary work to move and align the frame and the tilting machine. This solves the problem of traditional tilting machines requiring manual assistance for alignment and having low docking efficiency.
[0020] In this embodiment, the two ends of the front slide rail 101 extend to both sides of the slide rail frame 1, the upper support 302 and the upper conveyor belt 303 are both located in front of the lower fixed clamp 203, and the front transfer frame 3 moves along the front slide rail 101 to both sides to achieve seamless docking with the conveyor station to the flipping station of the production line. No additional transition tooling is required for matching with the production line, reducing the manual assistance of personnel in the transfer work.
[0021] In this second embodiment, based on the first embodiment, a front transfer frame 3 is slidably connected to both sides of the front slide rail 101. The two front transfer frames 3 are used for sending out and sending in the frame respectively. When the welding of one side of the frame is completed, the front transfer frame 3 immediately moves it out of the flipping station, and at the same time, the front transfer frame 3 on the other side sends the frame to be processed in synchronously, so as to realize the continuous operation of the equipment and further improve the production efficiency.
[0022] The working principle of this embodiment is as follows: Two slide rail frames 1 are placed on the outer sides of the front and rear of the frame. The front transfer frame 3 is located below the front and rear sections of the frame. The height of the front transfer frame 3 is adjusted by the upper telescopic cylinder 301 to adapt to the height difference caused by the Z-shaped change at the front end of the frame. The frame is placed on both sides of the upper tilting frame 2. The front transfer frame 3 moves along the front slide rail 101 to the bottom of the frame. The upper telescopic cylinder 301 supports the upper conveyor belt 303 to rise from below and lift the frame. The upper conveyor belt 303 and the frame move along the slide rail frame 1 with the front transfer frame 3 to align with the lower fixing clamp 203. The horizontal telescopic cylinder 102 pushes the upper tilting frame 2 to move closer to the frame. The vertical telescopic cylinder 201 adjusts the height of the tilting module 202 so that the lower fixing clamp 203 and the upper fixing clamp 205 of the tilting module 202 are above and below the frame, respectively. The middle telescopic cylinder 204 drives the upper fixing clamp 205. The lower fixed clamp 203 and the upper fixed clamp 205 clamp the frame, and the flipping module 202 drives the lower fixed clamp 203 and the upper fixed clamp 205 to flip the frame 360 degrees. Before flipping, the front transfer frame 3 moves to the outside along the slide rail frame 1 to avoid the front transfer frame 3 from getting stuck on the frame being flipped. The middle telescopic cylinder 204 drives the upper fixed clamp 205 to move up away from the frame, and the frame is released back to the lower front transfer frame 3. The front transfer frame 3 drives the frame to move outward, realizing the switching between the frame after flipping and the frame that needs to be flipped. This avoids the existing flipping machine being located at both ends of the frame, which requires auxiliary work to move and align the frame and the flipping machine, or to directly perform welding work on the flipping machine, resulting in the flipping machine being occupied for a long time. This effectively solves the industry pain points of traditional flipping machines that require manual assistance for alignment and have low docking efficiency. The upper conveyor belt 303 and the front transfer frame 3 drive the frame to move horizontally and adjust its position. The frame moves to the conveyor mechanism on both sides, realizing the seamless docking of the frame from the conveyor station to the flipping station. It directly realizes the docking and transfer of the frame and the conveyor platform on both sides of the front transfer frame 3, realizing the compatibility of the production line. The matching with the production line does not require additional transition tooling, reducing the manual assistance of personnel for transfer and significantly reducing labor costs.
