[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] In one embodiment, see Figures 1-8 A welding fixture for a motorcycle bumper includes a base 1, a U-shaped tube clamping mechanism 2, and a support tube clamping mechanism 3;

[0024] The support tube clamping mechanism 3 includes a first clamping head assembly 9 disposed on one side of the base 1 and whose spatial position is adjustable. The first clamping head assembly 9 is detachably connected to the support tube 43. The support tube clamping mechanism 3 is disposed on the upper right side of the base 1, so that the support tube 43 is stably fixed on the upper right side of the base 1 in a front-back orientation, which facilitates subsequent welding processing.

[0025] The U-shaped tube clamping mechanism 2 is located on the left side of the base 1. It includes a rotating disk 21 located on the left side of the front and rear sides of the base 1. A second sliding sleeve 17 is rotatably connected above the rotating disk 21. The second sliding sleeve 17 can rotate back and forth. A second sliding column 18 is slidably connected above the second sliding sleeve 17. A second clamping head assembly 19 is located above the second sliding column 18. The second clamping head assembly 19 can fix the front and rear sides of the U-shaped tube 44, so that the U-shaped tube 44 is fixed on the left side above the base 1 with its opening facing to the right. An auxiliary height adjustment component 20 is provided at the left end of the base 1. The auxiliary height adjustment component 20 can adjust the height of the U-shaped tube 44.

[0026] In one embodiment, a first sliding sleeve 4 is vertically arranged on the right end of the upper surface of the base 1. A first sliding post 6 is slidably connected above the first sliding sleeve 4. A first locking bolt 5 is threadedly connected to the upper side wall of the first sliding sleeve 4. The first locking bolt 5 can tighten the first sliding post 6, thereby limiting the height of the first sliding post 6. A fixed platform 7 is fixedly connected to the upper end of the first sliding post 6, which is arranged in a front-to-back orientation. Guide slide rods 8 are slidably connected to the front and rear ends of the fixed platform 7, which are arranged in a left-to-right orientation. The left end of the guide slide rod 8 is connected to the first clamping head assembly 9. Therefore, the vertical adjustment of the first clamping head assembly 9 can be controlled by the relative sliding of the first sliding post 6 and the first sliding sleeve 4. The horizontal adjustment of the first clamping head assembly 9 is realized by the sliding of the fixed platform 7 and the guide slide rod 8, thereby realizing the adjustment of the spatial position of the support tube 43.

[0027] In one embodiment, the first clamping head assembly 9 includes an L-shaped placement plate 10 fixedly connected to the left end of the guide slide bar 8. The L-shaped placement plate 10 includes a vertical plate fixedly connected to the guide slide bar 8 and a horizontal plate fixedly connected to the lower end of the vertical plate at the bottom of the L-shaped placement plate 10. A fixing plate 13 is fixedly connected to the middle right side of the vertical plate of the L-shaped placement plate 10. A vertically arranged sliding rod 14 is slidably connected to the middle of the fixing plate 13. The lower end of the sliding rod 14 is fixedly connected to a... A clamping spring 12 is provided between the positioning plate 11, the limiting plate 11, and the fixing plate 13. The clamping spring 12 is sleeved on the outside of the sliding rod 14, and the right end of the pressure plate 15, which is arranged in a front-to-back orientation, is fixedly connected to the upper end of the sliding rod 14. A pressure head 16 is provided on the lower surface of the left end of the pressure plate 15. The clamping spring 12 will pull the pressure plate 15 downward, so that after the support tube 43 is placed on the L-shaped placement plate 10, the pressure head 16 can press the support tube 43 tightly, thereby achieving the fixing effect of the support tube 43.

[0028] In one embodiment, the lower surface of the rotating disk 21 is rotatably connected to the base 1. A mounting bracket 22 oriented left and right is provided above the rotating disk 21. The mounting bracket 22 is a U-shaped structure with the opening facing upward. The upper end of the mounting bracket 22 is rotatably connected to a rotating shaft 23 oriented left and right. The middle part of the rotating shaft 23 is fixedly connected to the lower end of the second sliding sleeve 17. The upper part of the second sliding sleeve 17 is slidably connected to the second sliding column 18. The upper end of the second sliding column 18 is rotatably connected to the second clamping head assembly 19. Therefore, the second clamping head assembly 19 deflects left and right along the upper end of the second sliding column 18, and the lower end of the second sliding sleeve 17 deflects back and forth along the rotating shaft 23. An angle reset assembly 29 is provided on the outside of the rotating disk 21. The angle reset assembly 29 causes the two upper second clamping head assemblies 19 to move away from each other.

[0029] In one embodiment, the angle reset assembly 29 includes an extension plate 24 fixedly connected to the rotating disk 21. The end of the extension plate 24 away from the rotating disk 21 is rotatably connected to the lower end of the support plate 25. The upper end of the support plate 25 is rotatably connected to the side of the slider 26. The middle part of the slider 26 is slidably connected to the middle part of the second sliding sleeve 17. A limiting ring 28 is provided above the second sliding sleeve 17. A reset spring 27 is provided between the limiting ring 28 and the slider 26. The reset spring 27 is sleeved on the outside of the second sliding sleeve 17. The reset spring 27 will pull the slider 26 upward, thereby causing the second sliding sleeve 17 to deflect toward the extension plate 24. That is, the extension plate 24 can be set to be perpendicular to the rotation axis 23, which makes it easier to pull the second sliding sleeve 17 to deflect.

[0030] In one embodiment, the second clamping head assembly 19 includes a U-shaped clamping frame 30 rotatably connected to the upper end of the second sliding column 18. The opening of the U-shaped clamping frame 30 faces away from the center of the base 1, and a vertically arranged clamping screw 32 is threadedly connected to the middle of the upper plane of the U-shaped clamping frame 30. A clamping piece 31 is rotatably connected to the lower end of the clamping screw 32. The clamping piece 31 is disposed inside the U-shaped clamping frame 30. Therefore, the U-shaped tube 44 is pressed into the U-shaped clamping frame 30 by the clamping piece 31 to achieve the fixing effect of the U-shaped tube 44.

[0031] In one embodiment, the auxiliary height adjustment component 20 includes a third sliding sleeve 33 vertically disposed at the middle of the left end of the upper surface of the base 1. A vertically disposed third sliding post 35 is slidably connected above the third sliding sleeve 33, and a second locking bolt 34 that cooperates with the third sliding post 35 is threadedly connected to the side of the third sliding sleeve 33. The second locking bolt 34 can press against the third sliding post 35, thus fixing the height of the third sliding post 35. The right end of a left-right oriented placement platform 36 is fixedly connected to the upper end of the third sliding post 35. A rotating seat 38 is disposed on the right side of the upper surface of the placement platform 36. The right side of a left-right oriented guide sleeve 41 is rotatably connected above the rotating seat 38. A limiting frame 39 is disposed on the left side of the placement platform 36. The left side can extend into the interior of the limiting frame 39, and a limiting spring 40 is set between the upper part of the limiting frame 39 and the upper surface of the guide sleeve 41. The limiting spring 40 pushes the guide sleeve 41 to rotate counterclockwise. A pad 37 that cooperates with the guide sleeve 41 is set on the left side of the upper surface of the placement platform 36. Therefore, when the guide sleeve 41 rotates counterclockwise and contacts the pad 37, the guide sleeve 41 is in a horizontal state. The right side of the guide sleeve 41 is slidably connected to the limiting hook 42. The upper right end of the limiting hook 42 is set as an inclined surface, and the inside of the guide sleeve 41 is set with a spring that pulls the limiting hook 42 to slide to the left. Therefore, when the limiting hook 42 moves to the right, it will first deflect downward and pass the middle of the U-shaped tube 44. At this time, the limiting hook 42 can hook the U-shaped tube 44, thus achieving the effect of fixing the U-shaped tube 44.

[0032] In this embodiment, the base 1 is placed stably on the ground. First, the second sliding sleeve 17 on the front or rear side is pushed, causing the two second clamping head assemblies 19 to move closer to each other. At this time, the U-shaped tube 44 to be welded is taken out, and the front and rear sides of the U-shaped tube 44 are fixed to the front and rear two second clamping head assemblies 19 respectively. The second sliding sleeve 17 is released, and the two second sliding sleeves 17 move away from each other, thereby locking the U-shaped tube 44. The front and rear sides of the U-shaped tube 44 are usually set at an angle, so the left and right deflection of the U-shaped tube 44 is also locked, achieving the angle locking effect. The third sliding column 35 is moved up and down so that the height of the limiting hook 42 meets the welding height of the U-shaped tube 44. At this time, the U-shaped tube 44 is raised to the same height as the limiting hook 42. The limiting hook 42 is pushed to the right. After the limiting hook 42 moves to the right side of the front and rear facing horizontal bar on the left side of the U-shaped tube 44, the limiting hook 42 is released, and the limiting hook 42 will be hooked onto the U-shaped tube 44. At this time, the height of the U-shaped tube 44 is locked.

[0033] According to the shape of the U-shaped tube 44, when the two tubes on the right side of the U-shaped tube 44 are open, the first clamping head assembly 9 can be moved to the right side of the U-shaped tube 44. At this time, the support tube 43 can be fixed by the first clamping head assembly 9. During welding, the support tube 43 can be moved to the left. When the two tubes on the right side of the U-shaped tube 44 are closed, the first clamping head assembly 9 can be moved to the inside of the U-shaped tube 44. At this time, the support tube 43 is fixed by the first clamping head assembly 9. When welding is required, the support tube 43 can be moved to the right so that the end of the support tube 43 is close to the U-shaped tube 44.

[0034] This invention relates to a welding fixture for a motorcycle bumper. By setting a second sliding sleeve 17 that can be freely deflected to drive the second clamping head assembly 19 to move, the second clamping head assembly 19 can move adaptively in space when clamping the U-shaped tube 44, thereby making it easier to fix the U-shaped tube 44 during the welding process and making the entire fixture more convenient to use.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
