[0028] As Figures 1 to 10 shown, the structure and function of a multi-angle positioning fixture for welding motorcycle frame iron parts will be described in detail below;

[0029] A multi-angle positioning fixture for welding motorcycle frame iron parts includes a device bracket 11. Both the front and rear sides of the device bracket 11 are fixedly connected with a transverse movement bracket I 12. A transverse movement seat I 21 is slidably connected to the transverse movement bracket I 12. A telescopic mechanism I 22 is fixedly connected to the transverse movement seat I 21.

Two swing motors 25 are fixedly connected to the rotating ring 24. Output shafts of the two swing motors 25 are fixedly connected with swing brackets 26. Clamping mechanisms I 3 are fixedly connected to the two swing brackets 26. A power mechanism for driving the rotating ring 24 to rotate is fixedly connected to the lifting bracket 23. The power mechanism is preferably a servo motor;

[0030] During use, as Figure 1 shown, the motorcycle frame iron parts to be clamped are placed between the four clamping mechanisms I 3. A lead screw I 13 is rotatably connected to the transverse movement bracket I 12. A drive motor I 14 for driving the lead screw I 13 to rotate is fixedly connected to the transverse movement bracket I 12. The transverse movement seat I 21 is slidably connected to the transverse movement bracket I 12. The transverse movement seat I 21 is threadedly connected to the lead screw I 13;

[0031] Start the driving motor I 14. The driving motor I 14 is preferably a servo motor. The output shaft of the driving motor I 14 drives the lead screw I 13 to rotate. When the lead screw I 13 rotates, it drives the transverse movement of the transverse movement seat I 21 through the thread. The transverse movement seat I 21 drives the telescopic mechanism I 22 to move horizontally. The telescopic mechanism I 22 drives the lifting bracket 23 to move horizontally. The lifting bracket 23 drives the rotating ring 24 to move horizontally. The rotating ring 24 drives the swing motor 25 to move horizontally. The swing motor 25 drives the swing bracket 26 to move horizontally. The swing bracket 26 drives the clamping mechanism I 3 to move horizontally, adjusting the horizontal position of the clamping mechanism I 3, and then adjusting the clamping position of the clamping mechanism I 3 on the motorcycle frame iron part according to the length and processing requirements of the motorcycle frame iron part;

[0032] Clamp the motorcycle frame iron parts with different shapes by four clamping mechanisms I 3. Start the telescopic mechanism I 22. The telescopic mechanism I 22 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 22 drives the lifting bracket 23 to move up and down. The lifting bracket 23 drives the rotating ring 24 to move up and down. The rotating ring 24 drives the swing motor 25 to move up and down. The swing motor 25 drives the swing bracket 26 to move up and down. The swing bracket 26 drives the clamping mechanism I 3 to move up and down. The clamping mechanism I 3 drives the motorcycle frame iron part to move, and then adjusts the height of the motorcycle frame iron part, and adjusts the height of the motorcycle frame iron part according to the requirements and welding position;

[0033] Start the power mechanism. The output shaft of the power mechanism drives the rotating ring 24 to rotate. The rotating ring 24 drives the swing motor 25 to rotate. The swing motor 25 drives the swing bracket 26 to rotate. The swing bracket 26 drives the clamping mechanism I 3 to rotate. The clamping mechanism I 3 drives the motorcycle frame iron part to rotate, and then adjusts the angle of the motorcycle frame iron part, and adjusts the angle of the motorcycle frame iron part according to the requirements and welding position;

[0034] The structure and function of the clamping mechanism I 3 will be described in detail below;

[0035] The clamping mechanism I 3 includes a telescopic mechanism II 31. The telescopic mechanism II 31 is fixedly connected to the swing bracket 26. A clamping frame 32 is fixedly connected to the telescopic end of the telescopic mechanism II 31. A plurality of sliding columns are slidably connected to the clamping frame 32. A clamping block 33 is fixedly connected to each sliding column. A compression spring is fixedly connected between the sliding column and the clamping frame 32;

[0036] A telescopic mechanism III 34 is fixedly connected to the clamping frame 32. A positioning plate 35 is fixedly connected to the telescopic end of the telescopic mechanism III 34. The positioning plate 35 can contact the sliding column;

[0037] When clamping, the telescopic mechanism II 31 is started. The telescopic mechanism II 31 and the telescopic mechanism III 34 can be hydraulic cylinders or electric push rods. During use, the iron parts of the motorcycle frame to be clamped and fixed are placed on a plurality of clamping blocks 33. The plurality of clamping blocks 33 slide according to the shape of the iron parts of the motorcycle frame, so that the plurality of clamping blocks 33 form different height positions in the clamping frame 32. The telescopic mechanism II 31 is started, and the telescopic end of the telescopic mechanism II 31 drives the two clamping mechanisms I 3 on the same side to approach each other, so that the plurality of clamping blocks 33 contact the iron parts of the motorcycle frame. Then, under the reverse push of the iron parts of the motorcycle frame, the plurality of clamping blocks 33 on the two clamping mechanisms I 3 generate different deformations to adapt to the shape of the iron parts of the motorcycle frame. The telescopic mechanism III 34 is started, and the telescopic end of the telescopic mechanism III 34 drives the positioning plate 35 to move, so that the positioning plate 35 squeezes and positions the sliding column, and then squeezes and positions the plurality of clamping blocks 33 to complete the clamping of the iron parts of the motorcycle frame;

[0038] Due to the irregularity of the shape of the iron parts of the motorcycle frame, that is, there may be a certain inclined plane on the shape of the iron parts of the motorcycle frame, that is, there may be a certain inclined plane at the position of the iron parts of the motorcycle frame that needs to be clamped by the clamping mechanism I 3. Therefore, in order to make the clamping mechanism I 3 adapt to the inclination of the iron parts of the motorcycle frame, the clamping mechanism I 3 also needs to be inclined;

[0039] The way of angle adjustment here is that the swing motor 25 can be started. The swing motor 25 is preferably a servo motor. The output shaft of the swing motor 25 drives the swing bracket 26 to swing, and the swing bracket 26 drives the clamping mechanism I 3 to swing, so that the plurality of clamping blocks 33 on the clamping mechanism I 3 are inclined, so that the plurality of clamping blocks 33 adapt to the angle of the inclined plane of the iron parts of the motorcycle frame and adapt to the shapes of different iron parts of the motorcycle frame;

[0040] Furthermore, during the welding process of the iron parts of the motorcycle frame, it may involve a change in the clamping position of the iron parts of the motorcycle frame. Therefore, an auxiliary clamping is required to change the position of the iron parts of the motorcycle frame between the four clamping mechanisms I 3;

[0041] A transverse movement support II 15 is fixedly connected to the middle of the device support 11. An adjustment mechanism 4 is slidably connected to the transverse movement support II 15, and two clamping mechanisms II 5 are connected to the adjustment mechanism 4;

[0042] A lead screw II 16 is rotatably connected to the transverse movement support II 15, and a drive motor II 17 for driving the lead screw II 16 to rotate is fixedly connected to the transverse movement support II 15;

[0043] The adjustment mechanism 4 includes a transverse movement seat II 41. The transverse movement seat II 41 is slidably connected to the transverse movement support II 15 and is threadedly connected to the lead screw II 16;

[0044] Two telescopic mechanisms Ⅳ42 are fixedly connected to the transverse moving base Ⅱ41. Rotating motors Ⅰ43 are fixedly connected to the telescopic ends of the two telescopic mechanisms Ⅳ42. Telescopic mechanisms Ⅴ44 are fixedly connected to the output shafts of the two rotating motors Ⅰ43. Clamping mechanisms Ⅱ5 are fixedly connected to the telescopic ends of each telescopic mechanism Ⅴ44;

[0045] The clamping mechanism Ⅱ5 includes a rotating motor Ⅱ51. The rotating motor Ⅱ51 is fixedly connected to the telescopic end of the telescopic mechanism Ⅴ44. Two telescopic mechanisms Ⅵ52 are fixedly connected to the output shaft of the rotating motor Ⅱ51. A moving belt mechanism 53 is fixedly connected to the telescopic end of each telescopic mechanism Ⅵ52;

[0046] During use, when it is necessary to change the clamping position of the clamping mechanism Ⅰ3 on the motorcycle frame iron part, start the driving motor Ⅱ17. The output shaft of the driving motor Ⅱ17 drives the lead screw Ⅱ16 to rotate. When the lead screw Ⅱ16 rotates, it drives the adjusting mechanism 4 to move through the thread. The adjusting mechanism 4 drives the clamping mechanism Ⅱ5 to move, thereby adjusting the position of the clamping mechanism Ⅱ5;

[0047] Start the telescopic mechanism Ⅳ42. The telescopic mechanisms Ⅳ42, Ⅴ44 and Ⅵ52 can be hydraulic cylinders or electric push rods. The telescopic end of the telescopic mechanism Ⅳ42 drives the rotating motor Ⅰ43 to move. The rotating motor Ⅰ43 drives the telescopic mechanism Ⅴ44 to move. The telescopic mechanism Ⅴ44 drives the clamping mechanism Ⅱ5 to move, thereby adjusting the distance between the two clamping mechanisms Ⅱ5 on both sides;

[0048] Start the rotating motor Ⅰ43. The output shaft of the rotating motor Ⅰ43 drives the telescopic mechanism Ⅴ44 to rotate. The telescopic mechanism Ⅴ44 drives the clamping mechanism Ⅱ5 to rotate, thereby adjusting the position and angle of the clamping mechanism Ⅱ5 and the motorcycle frame iron part; meeting the requirements for welding position adjustment;

[0049] Start the telescopic mechanism Ⅵ52. The telescopic end of the telescopic mechanism Ⅵ52 drives the moving belt mechanism 53 to move, so that the moving belt mechanism 53 contacts the motorcycle frame iron part to clamp the motorcycle frame iron part, completing the auxiliary positioning of the motorcycle frame iron part. At this time, the clamping mechanism Ⅰ3 releases the clamping of the motorcycle frame iron part. The telescopic mechanisms Ⅳ42 and Ⅴ44 can be started to adjust the position of the motorcycle frame iron part relative to the clamping mechanism Ⅰ3, and the relative position of the clamping mechanism Ⅰ3 and the motorcycle frame iron part can be changed; meeting the requirements for welding position adjustment;

[0050] And the rotating motor Ⅱ51 can be started. The rotating motor Ⅱ51 drives the moving belt mechanism 53 to rotate, thereby rotating the motorcycle frame iron part and changing the relative position of the clamping mechanism Ⅰ3 and the motorcycle frame iron part; meeting the requirements for welding position adjustment;

[0051] Furthermore, the moving belt mechanism 53 can move. The moving belt mechanism 53 can be a conventional belt drive mechanism in the prior art. Through the belt drive mechanism, the iron parts of the motorcycle frame can be driven to move horizontally, changing the relative positions of the clamping mechanism I 3 and the iron parts of the motorcycle frame, meeting the requirements for welding position adjustment.
