Description

Technical Field

[0001] The utility model relates to the technical field of automobile frame production, in particular to a clamping and turning mechanism for automobile frame production. Background Art

[0002] In the automobile frame production process, the frame clamping and flipping mechanism plays a vital role. The precise clamping and stable flipping of the frame are not only related to the production efficiency, but also directly affect the manufacturing quality and safety of the frame. However, the existing frame clamping and flipping mechanism often has some problems, which limits its application in production.

[0003] Traditional frame clamping and flipping mechanisms have long relied on fixed clamping devices to perform their functions. However, this fixed design is incapable of dealing with frames of different sizes. Since the clamping device cannot be flexibly adjusted according to the size changes of the frame, whenever encountering frames of different sizes, the operator has to spend a lot of time and energy to replace the clamping device or readjust the entire mechanism. This not only significantly increases the complexity of operations in the production process, but also greatly reduces production efficiency, posing a considerable challenge to the smooth operation of the production line. More importantly, the stability and accuracy of the fixed clamping device when clamping frames of different sizes are often difficult to guarantee. Since the position of the clamping point and the size of the clamping force are fixed, when the frame size changes, the clamping effect is often unsatisfactory. The frame is prone to shaking or offset during the flipping process, which may not only cause the manufacturing accuracy of the frame to be damaged, but also cause safety issues, posing a threat to the safety of operators and equipment. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the utility model provides a clamping and flipping mechanism for automobile frame production, which has the advantages of being adaptable to frames of different sizes and improving the safety during the flipping process.

[0006] The flipping structure includes a motor fixedly connected to the upper surface of the base, a transmission rod is connected to the output shaft of the motor, a transmission wheel is externally connected to the transmission rod, a driven wheel is connected to the transmission wheel via a transmission belt, the driven wheel is rotatably connected to the second support plate via the driven rod, the supporting rod and the driven rod are respectively connected to the main frame at opposite ends, and a fixing component is arranged on the inner side of the main frame.

[0008] A further improvement to the above technical solution is that the right end of the transmission rod is rotatably connected to the second support plate, and the right end of the driven rod passes through the second support plate and is fixedly connected to the corresponding main frame.

[0009] A further improvement to the above technical solution is that: the first support plate and the second support plate are arranged relative to each other, the fixing assembly includes an elastic telescopic rod arranged on the inner side of the main frame, the outer end of the elastic telescopic rod is fixedly connected to the sub-frame, a rubber pad is fixed to the inner side of the sub-frame, the inner top wall and the inner bottom wall of the sub-frame are respectively fixed with relatively arranged cylinders, the end of the cylinder piston rod is connected to a fixing plate, and the two relatively fixing plates constitute a clamping part of the frame.

[0020] It should be noted that the left end of the slide bar 2 is fixedly connected to the inner left side wall of the base 1, and the right end of the slide bar 2 is fixedly connected to the inner right side wall of the base 1. The upper surface of the base 1 is provided with a sliding opening adapted to the slider 3. The right end of the transmission rod 8 is rotatably connected to the left side wall of the second support plate 6. The right end of the driven rod 12 sequentially penetrates the left and right side walls of the second support plate 6 and is fixedly connected to the corresponding main frame 13. The connection relationship between the driven rod 12 and the second support plate 6 is a rotational connection.

[0021] The first support plate 4 is located on the right side of the second support plate 6, and the fixing assembly includes an elastic telescopic rod 14 fixedly connected to the inner side of the main frame 13, a sub-frame 15 fixedly connected to one end of the piston rod of the elastic telescopic rod 14, a rubber pad 16 fixedly connected to the inner side of the sub-frame 15, a cylinder 17 fixedly connected to the inner top wall and inner bottom wall of the sub-frame 15 respectively, and a fixing plate 18 fixedly connected to one end of the piston rod of the cylinder 17, the left elastic telescopic rod 14 is fixedly connected to the inner left side wall of the left main frame 13, the right elastic telescopic rod 14 is fixedly connected to the inner right side wall of the right main frame 13, the left rubber pad 16 is fixedly connected to the inner left side wall of the left sub-frame 15, and the right rubber pad 16 is fixedly connected to the inner right side wall of the right sub-frame 15.

[0022] In this embodiment, the upper surface and the bottom of the sub-frame 15 are fixedly connected with connecting blocks 19, and the inner sides of the two connecting blocks 19 are slidably connected with connecting rods 20, the left end of the left connecting rod 20 is fixedly connected to the inner left side wall of the left main frame 13, and the right end of the left connecting rod 20 is bent upward and fixedly connected to the inner top wall of the left main frame 13, the right end of the right connecting rod 20 is fixedly connected to the inner right side wall of the right main frame 13, and the left end of the right connecting rod 20 is bent upward and fixedly connected to the inner top wall of the right main frame 13.

[0025] Then, the frame is clamped between the opposite sides of the two rubber pads 16, and the cylinders 17 on the upper and lower sides are started. The cylinders 17 on the upper and lower sides apply clamping force to the frame through the fixing plate 18. When the frame is clamped, the elastic telescopic rod 14 can be adaptively adjusted according to the size and shape of the frame to ensure that the clamping force can be evenly distributed on various key points of the frame. This evenly distributed clamping force can effectively prevent the frame from shaking or deflecting during the flipping process, thereby improving the stability of the clamping;

[0026] Finally, the transmission rod 8 is driven to rotate by starting the motor 7, and the transmission rod 8 then drives the transmission wheel 9 to rotate. The transmission wheel 9 drives the driven wheel 11 to rotate through the transmission belt 10, and the driven wheel 11 then drives the driven rod 12 to rotate. The driven rod 12 then drives the main frame 13 on the left to rotate. The main frame 13 on the left, in cooperation with the support rod 5 and the main frame 13 on the right, drives the clamped frame to flip.
