Description

Technical Field

[0001] This application relates to the adjustment technology in the welding process, and particularly to a welding adjustment device. Background Art

[0002] In equipment production, according to the design requirements of parts, it is necessary to weld rectangular frames of various different sizes, and there are relatively high requirements for the flatness of the welded rectangular frames.

[0003] When welding existing rectangular frames, usually two adjacent welded parts are first fixed on the ground, the welding joints are aligned and then welded. After completion, the remaining welded parts are gradually spliced and welded in turn. During the welding process, it is necessary to stop and repeatedly splice and measure each welding joint, and pre-splicing adjustment cannot be performed, which affects the welding efficiency. At the same time, there may be defects in the welded parts. If the welded parts cannot be pre-spliced, it is difficult to find the defects, resulting in the flatness of the finished rectangular frame after sequential welding not meeting the requirements and becoming scrap. Utility Model Content

[0004] This application provides a welding adjustment device to solve the problems of low welding efficiency of existing rectangular frames and difficulty in finding defects in welded parts and not being able to adjust in time.

[0005] This application provides a welding adjustment device, including two cross-connected horizontal bars on a horizontal plane. The top surfaces of the two horizontal bars are flush, and vertical bars are vertically fixed at the ends. Four slidably connected sleeves are sleeved on the horizontal bars. A fixing member is provided at the bottom of the sleeve, and an L-shaped support plate is provided at the top of the sleeve. Each side of each L-shaped support plate is perpendicular to each other. A baffle is fixed on one side of the L-shaped support plate, and a clamp is provided on the other side.

[0006] Optionally, the centers of the two horizontal bars are rotatably connected by a cylindrical rotating shaft, and the intersection of the two mutually perpendicular sides of the L-shaped support plate is hinged to the sleeve through a hinge shaft.

[0007] Optionally, a circular track is provided below the horizontal bar, and the bottom of the vertical bar is slidably connected to the track.

[0008] Optionally, a threaded rod is vertically inserted into the upper end of the vertical bar, the upper end of the threaded rod is rotatably connected to a hinge hinged to the end of the horizontal bar, and a handle is fixed to the upper end of the threaded rod.

[0009] Optionally, the baffle is fixedly arranged in an L shape on the inner side of the L-shaped support plate, and the clamp is installed on the outer sides of the two sides of the L-shaped support plate.

[0010] Compared with the prior art, the beneficial effects of the welding adjustment device provided by this application are:

[0011] According to the welding requirements of rectangular frames of different sizes, the position of the L-shaped support plate can be adjusted by sliding the sleeve. The welding parts are pre-assembled on the L-shaped support plate into the rectangular frame to be welded, and then clamped and fixed to align the welding joints at each corner. After the four welding parts forming the rectangular frame are assembled on the L-shaped support plate, the welding joints at each corner can be continuously welded in sequence, without repeated assembly and measurement during the welding process, thus improving the welding efficiency. After pre-assembly, defective welding parts can be promptly discovered and replaced or repaired to ensure the flatness of the welded rectangular frame and reduce the production of waste products.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following describes the technical solutions in the embodiments of this application clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts also belong to the scope of protection of this application.

[0022] As Figures 1-6 shown, an embodiment of this application provides a welding adjustment device, which includes two cross-connected horizontal bars 2 on a horizontal plane. The top surfaces of the two horizontal bars 2 are flush, and vertical bars 1 are vertically fixed at the ends. Four slidably connected sleeves 3 are sleeved on the horizontal bars 2. A fixing member 4 is provided at the bottom of the sleeve 3, and an L-shaped support plate 5 is provided at the top of the sleeve 3. Each side of each L-shaped support plate 5 is perpendicular to each other. A baffle 6 is fixed on one side of the L-shaped support plate 5, and a clamp 7 is provided on the other side.

[0023] The clamp 7 is composed of a positioning rod, a clamping block, and a spring. The positioning rod is perpendicularly fixed to the side end of the L-shaped support plate 5 with the baffle 6. The clamping block is slidably connected along the positioning rod. The spring is used to squeeze the clamping block towards the baffle 6, and the welding piece 14 is clamped between the clamping block and the baffle 6 by the elastic force of the spring.

[0024] During use, slide the sleeve 3 along the horizontal bar 2 according to the size of the rectangular frame to be welded, adjust the distance between the L-shaped support plates 5 to set the side length of the rectangular frame. After adjustment, tighten the fixing member 4 to lock and fix the sleeve 3. Place the welding pieces 14 forming the rectangular frame along the length direction on the opposite sides of two adjacent L-shaped support plates 5, align the welding joints of the two adjacent welding pieces 14, and then clamp and fix the welding pieces 14 through the clamp 7. Fix the four welding pieces 14 on the L-shaped support plates 5, align the welding joints, and then weld them in sequence.

[0025] In this embodiment, according to the welding requirements of rectangular frames of different sizes, the position of the L-shaped support plate 5 can be adjusted by sliding the sleeve 3. The welding pieces 14 are pre-assembled on the L-shaped support plate 5 into a rectangular frame to be welded, clamped and fixed, and the welding joints at each corner are aligned. After the four welding pieces 14 forming the rectangular frame are assembled on the L-shaped support plate 5, the welding joints at each corner can be continuously welded in sequence, without repeatedly assembling and measuring during the welding process, improving the welding efficiency. After pre-assembly, defective welding pieces 14 can also be found in time for replacement or repair, ensuring the flatness of the welded rectangular frame and reducing the generation of waste products.

[0026] In a possible implementation manner, the centers of the two horizontal bars 2 are rotatably connected through a cylindrical rotating shaft 8, and the intersection of the two mutually perpendicular sides of the L-shaped support plate 5 is hinged to the sleeve 3 through a hinge shaft 9.

[0027] Rotate the cross bar 2 around the cylindrical rotating shaft 8, and the distance between two adjacent L-shaped brackets 5 can be adjusted arbitrarily; rotate the L-shaped bracket 5 around the hinge shaft 9, and each side of the L-shaped bracket 5 can be adjusted to be perpendicular. By rotating the cross bar 2 and the L-shaped bracket 5, the length-width ratio of the rectangular frame can be adjusted, which is more flexible than only adjusting the size of the rectangular frame proportionally by sliding the sleeve 3.

[0028] In a possible implementation manner, a circular track 10 is provided below the cross bar 2, and the bottom of the vertical bar 1 is slidably connected to the track 10.

[0029] When the cross bar 2 rotates around the cylindrical rotating shaft 8, the vertical bar 1 slides along the circular track 10. The track 10 can reduce the friction during movement and limit the rotation direction, making the adjustment of the length-width ratio of the rectangular frame smoother and more convenient.

[0030] As Figure 5 shown, in a possible implementation manner, a threaded rod 11 is vertically inserted into the upper end of the vertical bar 1, the upper end of the threaded rod 11 is rotatably connected to a hinge 12 hinged to the end of the cross bar 2, and a handle 13 is fixed to the upper end of the threaded rod 11. The hinge 12 can use a ball head universal joint, which can not only not affect the rotation of the threaded rod 11, but also achieve the purpose of adjusting and changing the included angle between the cross bar 2 and the vertical bar 1.

[0031] Grasping the handle 13 can rotate the threaded rod 11 to adjust the length of the threaded rod 11 screwed into the vertical bar 1, so as to achieve the purpose of lifting one end of the cross bar 2. Thus, the height of the L-shaped bracket 5 corresponding to one end of the cross bar 2 can be adjusted, and the corners of the rectangular frame can be adjusted to the same horizontal plane, avoiding the welded rectangular frame from being uneven.

[0032] As Figure 6 shown, in a possible implementation manner, the baffle 6 is fixedly arranged in an L shape on the inner side of the L-shaped bracket 5, and the clamp 7 is installed on both outer sides of the L-shaped bracket 5.

[0033] The L-shaped baffle 6 is fixed on the inner side of the L-shaped bracket 5, which can not only play a role in limiting and clamping the welded part 14, but also avoid blocking, so that the longer welded part 14 can extend from the right angle of the L-shaped bracket 5, making the welding operation more flexible and convenient.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
