Abstract
Description
Technical Field
[0001] The utility model patent relates to pipeline processing equipment, specifically to a square pipe welding tool. Background Art
[0002] As a common building material, square tubes are widely used in various building structures. There are many ways to connect square tubes in building structures, among which welding is the most common. The various pipe fittings of the square tube can be pre-welded and then assembled to meet the needs of building a pipe rack structure.
[0003] In the prior art, when welding square tubes, a manual handheld welding torch is usually used to weld and fix the butt joint of the square tube. Among them, it is necessary to ensure that the positions of the two butted square tubes are relatively stable and meet the welding requirements. Smaller pipe fittings can be placed on a horizontal table for welding and fixing, while longer pipe fittings are usually placed on the ground for welding. However, the ground conditions are complicated and it is impossible to ensure that all positions are located on the same horizontal plane. Affected by the length of the tube, the support height of the ground at different positions for the tube body may be different. The square tube body is uneven when it is butt jointed, affecting welding. If the tube body is placed on the table, affected by the effective support area of the table, the overhanging pipe section lacks support, making the tube body prone to warping or tilting and unable to meet the welding requirements. If the pipe fittings are placed by expanding the area of the table, the table will occupy a large space when not in use, which is not conducive to the overall layout of the surrounding space. Summary of the invention
[0004] The utility model provides a square tube welding tool, which can ensure the supporting stability of a relatively long square tube on a table plate and will not occupy too much space when idle.
[0005] In order to achieve the above-mentioned purpose, the technical solution adopted is: a square tube welding tool, including a table plate, the lower end surface of the table plate is connected to a support frame, and a clamping mechanism consisting of a first clamping table and a second clamping table is arranged on the table surface of the table plate. The first clamping table and the second clamping table are provided with positioning grooves for placing the square tubes to be welded, and the through-direction of the positioning groove is in the horizontal direction. The bottom edges of the positioning grooves of the first clamping table and the second clamping table are connected with support pipes which are arranged along the through-direction of the positioning groove and are retractable in length. The support pipes are cantilevered from the opposite sides of the first clamping table and the second clamping table to the outer edge of the table plate, and the upper end surface of the suspended end is connected to a support table, and the support table and the bottom surface of the positioning groove are in the same horizontal plane.
[0006] Compared with the prior art, the technical effect of the utility model is as follows: by connecting the supporting pipes arranged along the through direction of the positioning groove and having a retractable length at the bottom edge of the positioning groove of the first clamping platform and the second clamping platform, the relative distance between the supporting platform and the positioning groove can be adjusted according to the length of the square tube, and the bottom of the positioning groove and the supporting platform on the same horizontal plane can be used to jointly support the tube body, which can ensure the stability of the tube body and the horizontality of the pipe. In addition, when idle, the length of the supporting pipe can be shortened to reduce the space occupied by the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following will be combined with the attached Figure 1-4 The embodiments of the technical solution of the present application are described in detail. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application:
[0012] A square tube welding tool comprises a table 10, the lower end surface of the table 10 is connected to a support frame 11, a clamping mechanism 20 consisting of a first clamping platform 21 and a second clamping platform 22 is arranged on the table surface of the table 10, the first clamping platform 21 and the second clamping platform 22 are provided with positioning grooves for placing the square tubes to be welded, the through direction of the positioning grooves is in the horizontal direction, the bottom edges of the positioning grooves of the first clamping platform 21 and the second clamping platform 22 are connected with support pipes which are arranged along the through direction of the positioning grooves and are retractable in length in the direction of the tube length, the support pipes are cantilevered from the opposite sides of the first clamping platform 21 and the second clamping platform 22 to the outer edge of the table 10, and the upper end surface of the cantilevered end is connected to a support platform 32, and the support platform 32 and the bottom surface of the positioning groove are in the same horizontal plane.
[0013] In the above scheme, when welding the square tube, the two square tubes are placed in the first clamping platform 21 and the second clamping platform 22 along the through direction of the positioning grooves and fixed therein, and the distance between the opposite ends of the two square tubes is adjusted so that the end faces are close to each other for welding. By connecting the support pipes arranged along the through direction of the positioning grooves and having a retractable length at the bottom edge of the positioning grooves of the first clamping platform 21 and the second clamping platform 22, the relative distance between the support platform 32 and the positioning grooves can be adjusted according to the length of the square tube, and the square tube is supported by the bottom of the positioning groove and the support platform 32 on the same horizontal plane, so as to avoid the suspension section of the square tube from falling under the action of gravity and causing the tube body to tilt, thereby ensuring the stability of the square tube body to be welded and the horizontality of the square tube. In addition, when idle, the length of the support pipes can be shortened to reduce the space occupied by the equipment.
[0014] As a preferred solution, the supporting pipe includes an outer pipe body 30 and an inner pipe body 31. The inner pipe body 31 is inserted into the tube cavity of the outer pipe body 30 to form a guide sliding fit. A support platform 32 is arranged on the upper end surface of the suspension end of the inner pipe body 31 away from the positioning groove. The extension length of the inner pipe body 31 in the outer pipe body 30 can be adjusted by pulling, thereby adjusting the effective length of the supporting pipe. According to the length of the square pipe to be welded, the distance between the support platform 32 and the positioning groove on the first clamping platform 21 or the second clamping platform 22 is adjusted to provide stable support for the pipe body of the square pipe.
[0015] Furthermore, the lower end surface of the suspension end of the inner tube body 31 away from the positioning groove is connected to a support rod 33, and the lower rod end of the support rod 33 is connected to a universal wheel 34 whose wheel bottom surface is at the same height as the lower end surface of the support frame 11. Through the cooperation of the support rod 33 and the universal wheel 34, the suspension end of the inner tube body 31 can be supported to prevent the suspension end of the supporting pipe from being bent and deformed due to lack of support.
[0016] In addition, a locking bolt 301 perpendicular to the length of the tube is provided on the tube wall of the outer tube body 30, and the bolt body of the locking bolt 301 penetrates the tube wall of the outer tube body 30 and forms a threaded fit with the through hole. The inner tube body 31 and the outer tube body 30 can be locked or unlocked by rotating the locking bolt 301, so as to ensure that the length of the supporting tube remains stable after the length adjustment.
[0017] Combination Figure 1-4As shown, in this solution, the first clamping platform 21 and the second clamping platform 22 both include a base 201 located on the table surface of the table 10, the upper end surface of the base 201 and the opposite surface of the clamping plate 202 standing at the opposite ends thereof enclose a positioning groove, and the adjusting bolt 203 inserted into the through hole on the plate surface of the clamping plate 202 forms a threaded fit with the through hole, and the bolt core direction of the adjusting bolt 203 is arranged along the slot width direction of the positioning groove and one end located in the positioning groove is connected to a fastening plate 204. When welding a square tube, the square tube to be welded is placed in the positioning groove along the through direction of the positioning groove, that is, on the upper end surface of the base 201. By rotating the adjusting bolt 203, the fastening plate 204 and the clamping plate 202 can be controlled to cooperate with each other to clamp the tube body of the square tube.
[0018] Considering that the welding of square tubes often requires welding at different angles, a circular arc-shaped guide groove 40 is provided on the table surface of the table 10, and the through direction of the positioning grooves on the first clamping table 21 and the second clamping table 22 is arranged along the radial direction of the guide groove 40, and the lower end surface of the second clamping table 22 is connected to a slider that forms a limit guide with the guide groove 40. Under the setting of the slider, the second clamping table 22 can move along the guide groove 40 to change its position, thereby changing the relative angle of the two square tubes clamped in the positioning grooves on the first clamping table 21 and the second clamping table 22 to meet the welding requirements. Here, a corresponding angle indication can be set on the table 10, and the fingertip 60 that moves with the second clamping table 22 can point to the corresponding scale to indicate the relative angle of the square tube, accurately meeting the welding requirements of the square tube at different angles.
[0019] The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
