Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy boutonniere welding, specifically an aluminum alloy boutonniere welding fixture. Background Technology

[0002] As a common form of traditional architectural railings, the "beauty's rest" mainly consists of a seat and a lumbar support. The seat is for the user to sit on, while the lumbar support is mainly composed of multiple vertical bars and horizontal bars fixed to the bars. The bars are mostly curved. The lumbar support is used to support the user's upper body and allows the user to lean against it.

[0003] During the production of aluminum alloy chaise lounges, the lumbar support needs to be welded to the seat surface, mainly by welding the lower end of the vertical rod to the seat surface. Currently, most aluminum alloy chaise lounge welding uses general-purpose clamps for fixation. Traditional clamps are mostly designed for straight lines or regular arcs, but the vertical rods of the lumbar support usually have complex curved surfaces. Traditional clamps are difficult to adapt to vertical rods with different curvature radii, resulting in unstable clamping, welding misalignment, and affecting welding accuracy. Moreover, due to the complex curved surface of the chaise lounge's vertical rods, fixed clamps need to frequently adjust the positioning points to ensure that the lumbar support can be clamped tightly during the welding process. Therefore, traditional clamps cannot quickly lock onto the chaise lounge seat surface, affecting the welding efficiency of the chaise lounge. Utility Model Content

The specific features of this aluminum alloy boutonniere welding fixture are described in detail below:

[0026] One embodiment of this utility model:

[0027] Reference Figures 1-7 This utility model provides an aluminum alloy boutonniere welding fixture, comprising:

[0028] A clamping assembly is used to clamp the waist part of an aluminum alloy boutonniere. The clamping assembly includes two vertically symmetrical rollers 37. A first clamping roller 35a is fixed on the rollers 37. Connecting strips 34 are provided on both sides of the two first clamping rollers 35a. The two rollers 37 pass through both ends of the connecting strips 34 and are fixedly connected to them. A connecting block 341 is fixed on the connecting strip 34. A first threaded rod 38 is slidably connected in the connecting block 341. A connecting seat 40 is fixed at the end of the first threaded rod 38. A second clamping roller 35b is rotatably connected between the two connecting seats 40. The second clamping roller 35b and the two first clamping rollers 35a are triangularly distributed. The second clamping roller 35b cooperates with the two first clamping rollers 35a to clamp the waist part of the aluminum alloy boutonniere.

[0029] An adjustment component is used to adjust the tilt angle of the clamping component. The adjustment component includes a fixed plate 20 and four traction rods 30, so that the clamping component can be adapted to aluminum alloy boutonnieres with different degrees of curvature.

[0030] A fixing component is used to secure the adjustment component and the clamping component to the surface of the boutonniere seat.

[0031] Two positioning rings are fixed on the roller 37 near its two ends, and the end of the traction rod 30 abuts against the positioning rings.

[0032] A nut 39, which can abut against the connecting block 341, is threaded onto the first threaded rod 38. A movable rod 36 is inserted through the second clamping roller 35b. A through hole parallel to the axis of the second clamping roller 35b is opened in the connecting seat 40. Both ends of the movable rod 36 can be inserted into the through hole on the connecting seat 40. An external spline (not shown) is opened on the movable rod 36. A sleeve is fixed inside the second clamping roller 35b. An internal spline (not shown) is opened in the inner wall of the sleeve and in the through hole of the connecting seat 40. The movable rod 36 cooperates with the spline of the sleeve and the through hole on the connecting seat 40, so that the second clamping roller 35b is fixed between the two connecting seats 40 and remains relatively stationary with the two connecting seats 40. The first clamping roller 35a is disposed between the second clamping roller 35b and the nut 39. Both the first clamping roller 35a and the second clamping roller 35b are made of rubber.

[0033] One end of each of the four traction rods 30 is rotatably connected to the ends of the two rollers 37. The two lower traction rods 30 are fixed to the upper surface of the fixing plate 20. The fixing plate 20 is provided with two support rods 32 that are parallel to the connecting strip 34. The other end of the traction rod 30 is rotatably connected to the end of the support rod 32. The support rod 32, the traction rod 30 on the same side, and the connecting strip 34 on the same side form a parallel quadrilateral. The upper ends of the two support rods 32 are rotatably connected to each other. The tilt angle of the connecting strip 34 can be adjusted by moving the center rod 33.

[0034] The upper surface of the fixed plate 20 is provided with a downwardly recessed guide groove 201 parallel to the length direction of the traction rod 30. Two hinge seats 22 are fixed on the upper surface of the fixed plate 20, symmetrically arranged around the guide groove 201. The lower end of the support rod 32 is rotatably connected to the hinge seat 22. A moving block 23 is slidably connected in the guide groove 201. A lead screw 21 is threadedly connected in the moving block 23. One end of the lead screw 21 extends out of the fixed plate 20 and a turntable is fixed on it. The two ends of the lead screw 21 are rotatably connected to the two side walls of the guide groove 201 respectively. An adjusting rod 31 is rotatably connected between the upper surface of the moving block 23 and the central rod 33. The length of the adjusting rod 31 is the same as the length of the support rod 32. The connection between the lower end of the adjusting rod 31 and the lower end of the support rod 32, and the adjusting rod 31 and the support rod 32 form an isosceles triangle. Since the triangle has stability, when the support rod 32 and the adjusting rod 31 do not coincide, the adjusting rod 31 and the support rod 32 can remain relatively stationary.

[0035] The fixing assembly includes a base plate 10, a top plate 11, and a clamping plate 15. The top plate 11 is disposed below the fixing plate 20. A connecting post 14 is fixed between the fixing plate 20 and the top plate 11. A connecting plate 13 is fixed between the top plate 11 and the base plate 10. A reinforcing rib 12, perpendicular to the connecting plate 13, is fixed between the top plate 11 and the base plate 10. The clamping plate 15 is disposed between the top plate 11 and the base plate 10. The clamping plate 15 and the reinforcing rib 12 are respectively disposed on both sides of the connecting plate 13. A second threaded rod 17 is rotatably connected to the lower end face of the clamping plate 15. A ring-shaped mounting seat is fixedly provided on the surface of the base plate 10. The upper end of the second threaded rod 17 is rotatably connected to the ring-shaped mounting seat. A groove for accommodating the mounting seat is provided on the upper end surface of the base plate 10. A threaded sleeve 16 is fixedly provided on the lower end surface of the base plate 10. The second threaded rod 17 passes downward through the base plate 10 and the threaded sleeve 16. The second threaded rod 17 is threadedly connected to the base plate 10 and the threaded sleeve 16. Two guide rods 18 that pass downward through the base plate 10 are fixedly provided on the lower end surface of the clamping plate 15. The guide rods 18 are slidably connected to the base plate 10. The clamping plate 15 cooperates with the top plate 11 to clamp the surface of the boutonniere seat.

[0036] When welding the lumbar support part of the bouncy rest to the seat surface, multiple clamps can be used to hold the lumbar support part of the bouncy rest.

[0037] When using this utility model, the fixing components on multiple clamps are first initially fixed on the seat surface of the beauty rest. The specific operation steps are as follows: the top plate 11 and the clamping plate 15 are clamped on the upper and lower sides of the seat surface, and the second threaded rod 17 is rotated to move the clamping plate 15 upward until the clamping plate 15 abuts against the lower end surface of the seat surface. Multiple clamps are equidistantly arranged along the length direction of the seat surface.

[0038] Then, multiple clamps clamp at multiple positions of the lumbar support section of the chaise longue along the seat surface at equal intervals (e.g., ...). Figure 1 (As shown), the specific operation steps are as follows:

[0039] First, place the lumbar support part of the beauty rest on the seat surface, with the lower end of the vertical rod of the lumbar support part abutting against the seat surface. Reverse the second threaded rod 17 so that the clamping plate 15 is away from the lower end of the seat surface, allowing the fixing component to move freely. Adjust the position of the clamping component so that it is aligned with the vertical rod of the lumbar support part. After removing the movable rod 36 from the through hole on the connecting seat 40, remove the second clamping roller 35b from between the two connecting seats 40. Then move the clamp towards the vertical rod of the lumbar support part so that one of the two first clamping rollers 35a abuts against the vertical rod.

[0040] If the first clamping roller 35a on the upper side first abuts against the vertical rod, the turntable at the end of the lead screw 21 is rotated in the forward direction, causing the lead screw 21 to rotate in the forward direction, thereby causing the moving block 23 to move away from the clamping assembly, thereby driving the upper end of the adjusting rod 31 to move away from the clamping assembly, thereby driving the center rod 33 to move away from the clamping assembly. Through the traction of the upper traction rod 30, the first clamping roller 35a on the upper side moves towards the hinge seat 22, thereby adjusting the tilt angle of the connecting strip 34 until the first clamping rollers 35a on both the upper and lower sides can simultaneously abut against the surface of the vertical rod of the waist rest part.

[0041] If the first clamping roller 35a on the lower side first comes into contact with the surface of the vertical rod of the waist support part, then reverse the turntable at the end of the screw 21 until the first clamping roller 35a on both the upper and lower sides comes into contact with the surface of the vertical rod.

[0042] Then, the second clamping roller 35b is placed between the two connecting seats 40, and the movable rod 36 is passed through the through holes on the two connecting seats 40 and the sleeve inside the second clamping roller 35b, so that the second clamping roller 35b is fixed between the two connecting seats 40 and located on the other side of the vertical rod of the waist support. Then, the nut 39 is rotated so that the second clamping roller 35b moves towards the connecting bar 34 until the second clamping roller 35b cooperates with the first clamping roller 35a to clamp the vertical rod of the waist support.

[0043] Subsequently, after moving the lumbar support part to the welding position, the clamp moves accordingly, and then the second threaded rod 17 is rotated, causing the clamping plate 15 to move upward until the clamping plate 15 and the top plate 11 clamp the seat surface of the lumbar support, thereby positioning the lumbar support part of the lumbar support on the seat surface to facilitate welding of the lumbar support part.

[0044] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
