Description

Technical Field

[0001] This utility model relates to the field of air conditioning pipe processing technology, and in particular to a long pipe welding positioning device. Background Technology

[0002] In the welding of existing air conditioning pipes, assembly is typically carried out using simple clamps. Long pipes are placed on ordinary supports, and after the connecting pipes are inserted, their relative positions are ensured by visual alignment or temporary supports, lacking standardized positioning benchmarks. During the welding process, long pipes and connecting pipes are prone to displacement or deflection, making it difficult to guarantee welding accuracy and resulting in poor consistency of finished products. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of the prior art and provide a long pipe welding positioning device that can quickly locate the position of connecting pipes and long pipes and facilitates processing.

[0004] To achieve the above objectives, the present invention adopts the following solution:

[0005] A long pipe welding positioning device includes a long pipe and a connecting pipe connected to the long pipe, and further includes:

[0006] The base frame has a tabletop, a mounting frame, and multiple spaced support blocks on the mounting frame. Each support block has a groove to accommodate a long tube. Two uprights are positioned on the mounting frame and in front of the support blocks. Each upright has a mounting seat. A connecting frame is positioned between the two mounting seats. The connecting frame has three rows of first positioning holes, each row including multiple first positioning holes arranged along the length of the connecting frame. The connecting frame also has positioning elements that can pass through the first positioning holes and be inserted into the opening of a connecting tube. A locking component is provided between the mounting frame and the tabletop to lock them together.

[0007] The mounting base is provided with a sliding hole. The mounting base is sleeved on the column through the sliding hole and can slide up and down along the column. A first adjustment component is provided between the mounting base and the column to adjust the position of the mounting base relative to the column. The first adjustment component includes a first through hole that extends laterally through the mounting base to the sliding hole. The first through hole is provided with a first locking member that can be threadedly connected to it. The first locking member can abut against the outer wall of the column to lock and fix the mounting base and the column.

[0008] The connecting frame includes a rotating block rotatably connected to each of the first locking members, each of the rotating blocks is provided with a transversely extending pin, a positioning plate is provided between two of the pins, and three rows of the first positioning holes are provided on the positioning plate.

[0009] In the three columns of the first positioning hole group, the first positioning holes in the left column and the first positioning hole group in the right column are aligned, and the first positioning holes in the middle column are staggered with the first positioning holes in the left column and the first positioning hole group in the right column along the length of the positioning plate.

[0010] The rotating block includes a plurality of second positioning holes arranged along its length. The side wall of the rotating block is provided with a plurality of third positioning holes that can be arranged along its width. The third positioning holes penetrate the side wall of the rotating block and intersect with the second positioning holes. The pin is transversely inserted through the second positioning holes. The third positioning holes are provided with a second locking member that can be threadedly connected to them. When the second locking member abuts against the pin, it can lock and fix the second locking member and the pin.

[0011] The positioning component includes a column, the lower end of which is provided with an arc-shaped surface, and the top end of which is provided with a gripping part.

[0012] The support block is provided with an inclined surface.

[0013] A pad and a cover plate are also provided between the first locking member and the rotating block.

[0014] The column is fitted with a sleeve, and the mounting base is slidably connected to the outside of the sleeve.

[0015] The locking component is an F-type clamp.

[0016] Compared with existing technologies, this utility model has the following advantages: When using this utility model, the long tube is placed in the support block of the mounting frame. The groove in the support block can position the long tube. Then, the connecting tube is inserted into the corresponding hole on the long tube. Then, the positioning component is inserted into the first positioning hole. The position of the long tube is adjusted by moving it left and right to ensure that each positioning component can be inserted into the first positioning hole and centered under its own weight. Since the position of the first positioning hole is fixed, it can be used as a benchmark to reject unqualified connecting tubes. When all the positioning components are aligned with each connecting tube, the worker can carry out the subsequent welding operation to weld and fix the connecting tube to the long tube. It can achieve precise positioning, simplify the tedious process of traditional multiple measurements and repeated adjustments, and significantly shorten the clamping time. At the same time, the locking component set between the mounting frame and the table can lock the two firmly to prevent the mounting frame from loosening or shifting. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] like Figures 1 to 6 As shown, a long pipe welding positioning device includes a long pipe 100 and a connecting pipe 101 connected to the long pipe 100. It also includes: a base frame 1, a table 2 mounted on the base frame 1, a mounting frame 3 mounted on the table 2, a plurality of spaced support blocks 31 mounted on the mounting frame 3, grooves 311 on the support blocks 31 capable of accommodating the long pipe 100, two columns 32 mounted on the mounting frame 3 and located in front of the support blocks 31, each column 32 having a mounting seat 33, a connecting frame 4 between the two mounting seats 33, three rows of first positioning holes in the connecting frame 4, each row including a plurality of first positioning holes 41 arranged along the length of the connecting frame 4, a positioning element 5 capable of passing through the first positioning holes 41 and being inserted into the opening of the connecting pipe 101, and a locking component 6 between the mounting frame 3 and the table 2 capable of locking the two together.

[0026] In use, the long tube 100 is placed in the support block 31 of the mounting frame 3. The groove 311 in the support block 31 can position the long tube 100. Then, the connecting tube 101 is inserted into the corresponding hole on the long tube 100. Then, the positioning member 5 is inserted into the first positioning hole 41. The position of the long tube 100 is adjusted by moving it left and right to ensure that each positioning member 5 can be inserted into the first positioning hole 41 under its own weight and set in the center. Since the position of the first positioning hole 41 is fixed, it can be used as a benchmark to remove unqualified connecting tubes 101. When all the positioning members 5 are aligned with each connecting tube 101, the worker can carry out the subsequent welding operation to weld and fix the connecting tube 101 to the long tube 100. It can achieve precise positioning, simplify the tedious process of traditional multiple measurements and repeated adjustments, and significantly shorten the clamping time. At the same time, the locking component 6 set between the mounting frame 3 and the table 2 can lock the two firmly to prevent the mounting frame 3 from loosening or shifting.

[0027] The mounting base 33 is provided with a sliding hole 331. The mounting base 33 is sleeved on the column 32 through the sliding hole 331 and can slide up and down along the column 32. A first adjustment component 34 is provided between the mounting base 33 and the column 32 to adjust the position of the mounting base 33 relative to the column 32. The first adjustment component 34 includes a first through hole 341 that extends laterally from the mounting base 33 to the sliding hole 331. The first through hole 341 is provided with a first locking member 342 that can be threadedly connected to it. The first locking member 342 can abut against the outer wall surface of the column 32 to lock and fix the mounting base 33 and the column 32. The mounting base 33 slides into the column 32 via the sliding hole 331, allowing the overall height of the connecting frame 4 to be adjusted up and down according to the height of the long connecting pipe 101. Combined with the locking function of the first adjusting component 34, the mounting base 33 is adjustable on the column 32, thus adapting to the welding needs of different specifications of long pipes 100 and connecting pipes 101 of different heights, broadening its applicability. The first locking component 342 locks against the outer wall of the column 32 through friction generated by threaded tightening, while also facilitating adjustment.

[0028] The connecting frame 4 includes rotating blocks 42 rotatably connected to each of the first locking members 342. Each rotating block 42 is provided with a transversely extending pin 43. A positioning plate 44 is provided between two of the pins 43, and three rows of the first positioning holes are provided on the positioning plate 44. The rotating blocks 42 and the first locking members 342 form a rotatable connection, allowing the positioning plate 44 to be adjusted in position. In conjunction with the pins 43, the positioning plate 44 can also achieve fine adjustment of the pitch angle, which can accurately adapt to the welding requirements of different spatial angles between the connecting pipe 101 and the long pipe 100, especially for positioning operations with complex angles such as oblique intersections and spatial intersections, and has a wide range of applications.

[0029] In the three columns of the first positioning hole group, the first positioning holes 41 in the left and right columns are aligned, while the first positioning holes 41 in the middle column are staggered with those in the left and right columns along the length of the positioning plate 44. This arrangement of the first positioning holes 41 allows the device to adapt to various spacing requirements of the connecting pipes 101 in different batches and specifications of long pipe welding tasks, thus broadening its applicability.

[0030] The rotating block 42 includes a plurality of second positioning holes 421 arranged along its length. The side wall of the rotating block 42 is provided with a plurality of third positioning holes 422 that can be arranged along its width. The third positioning holes 422 penetrate the side wall of the rotating block 42 and intersect with the second positioning holes 421. The pin 43 is transversely inserted through the second positioning holes 421. The third positioning holes 422 are provided with a second locking member 45 that can be threadedly connected to it. When the second locking member 45 abuts against the pin 43, it can lock and fix the second locking member 45 and the pin 43. Multiple second positioning holes 421 arranged along the length of the rotating block 42 enable multi-level progressive adjustment of the installation position of the pin 43 and the positioning plate 44, thereby changing the vertical distance between the positioning member 5 and the long tube 100 and changing the corresponding row of the first positioning holes 41; the third positioning hole 422 penetrates the side wall of the rotating block 42 and intersects with the second positioning hole 421 in a through-type structure, so that the second locking member 45 can directly act on the surface of the pin 43 that passes through the second positioning hole 421; the operator only needs to insert the pin 43 into the target second positioning hole 421 and then tighten the second locking member 45 to complete the quick locking.

[0031] The positioning component 5 includes a column 51, the lower end of which is provided with an arc-shaped surface 511, and the top end of which is provided with a gripping part 52. The gripping part 52 is designed for easy gripping by the user, and the arc-shaped surface 511 allows it to be easily inserted into the connecting tube 101, thus centering the connecting tube 101.

[0032] The support block 31 is provided with an inclined surface 312 to facilitate the insertion of the long tube 100.

[0033] A pad 71 and a cover plate 72 are also provided between the first locking member 342 and the rotating block 42. The pad 71 can precisely control the fitting gap between the rotating block 42 and the first locking member 342, and the cover plate 72 is used to protect the pad 71 and the end of the mounting base 33.

[0034] The column 32 is fitted with a sleeve 36, and the mounting base 33 is slidably connected to the sleeve 36. The sleeve 36 serves as an independent protective layer on the outside of the column 32 to protect it. Since the first locking member 342 presses against the outer wall of the sleeve 36 when locking, when the sleeve 36 wears out due to high-frequency use, only the sleeve 36 needs to be replaced, eliminating the need to replace the entire column 32. This reduces maintenance costs and replacement difficulty, and extends the service life of the column 32.

[0035] The locking component 6 is an F-type clamp, which is convenient to operate and clamps the table 2 and the mounting bracket 3.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
