Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, and particularly relates to a profile skeleton welding tool. Background Art

[0002] Profiles are objects with certain geometric shapes made of iron or steel and materials with certain strength and toughness through rolling, extrusion, casting and other processes. They are widely used, especially in the fields of guardrails, doors and windows. When using profiles to produce guardrails, doors and windows, the profiles need to be welded to obtain the profiles with the required angles. The welding of profiles is usually done manually. When welding, the two separated profile monomers need to be accurately positioned according to the required length, so that the profiles with the required length can be welded.

[0003] In existing frame welding, disposable special tooling is more commonly used. Different sizes of tooling must be made for frames of different sizes, which is time-consuming and material-intensive.

[0004] In view of the above problems in traditional assembly, it is necessary to design a device that can be pulled out to adjust the length and width span to meet the positioning welding of frames of different sizes. Summary of the invention

[0005] The purpose of the utility model is to provide a profile frame welding tool to meet the positioning welding of frames of different sizes in view of the deficiencies of the above-mentioned prior art.

[0009] During installation, the left end of the upper slide bar is fixedly connected to the left corner piece, and the right end thereof is movably arranged and a positioning platform is arranged at the end thereof, and a threaded hole is opened on the positioning platform and the slide bar is tightened to limit the position through the provided top screw;

[0010] The right side portion of the lower slide bar is fixedly connected to the right corner piece, and the left side portion is movably arranged with the upper slide bar.

[0011] The supporting sliding block comprises a fixing portion and a supporting portion, wherein the fixing portion is buckled on the outside of the rod body and fixedly connected to the rod body through a connecting bolt, and the fixing portion and the supporting portion at the front end are arranged in a step shape.

[0012] The support portion and the fixing portion are integrally formed, and the support portion extends to be located inside the frame body and is lower than the upper end surface of the fixing portion.

[0013] The connecting part between the rod and the corner piece is fixed by welding.

[0014] The frame body includes four groups of rods which are arranged to form a rectangular structure.

[0015] The beneficial effects of the utility model are:

[0022] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0023] The utility model provides a profile frame welding tool, such as Figures 1 to 5 shown.

[0024] A profile skeleton welding tool comprises a frame body formed by splicing a plurality of groups of rods, and adjacent rods are connected by angle pieces 3; each group of rod bodies comprises an upper slide bar 1 and a lower slide bar 2 which are slidably arranged up and down, and a supporting slide block 4 arranged on the rod body, and a wedge-shaped through groove 11 is formed on the lower end surface of the upper slide bar 1, and a wedge-shaped block 21 which can be inserted into the wedge-shaped through groove 11 is convexly provided on the upper end surface of the lower slide bar 2.

[0025] During installation, the left end of the upper sliding bar 1 is fixedly connected to the left corner piece, and the right end thereof is movably arranged and a positioning platform 12 is provided at its end. A threaded hole is opened on the positioning platform 12 and the lower sliding bar 2 is tightened to limit the position through a provided top screw 13; while the right side of the lower sliding bar 2 is fixedly connected to the right corner piece 3, and the left side thereof is movably arranged with the upper sliding bar 1.

[0026] The support slider 4 includes a fixing portion 41 and a supporting portion 42, and the fixing portion 41 is buckled on the outside of the rod body and fixedly connected to the rod body by connecting bolts, and the fixing portion 41 and the front end supporting portion 42 are arranged in a step-like manner. In order to improve the strength, the supporting portion 42 and the fixing portion 41 are integrally formed, and the supporting portion 42 extends to the inside of the frame body and is lower than the upper end surface of the fixing portion 41, which is convenient for supporting the skeleton operation inside.

[0027] In this embodiment, the frame body includes four groups of rods and are arranged in a rectangular structure. The rods and the corner pieces are fixed by welding, and the upper sliding rod 1 and the lower sliding rod 2 of the rods are slidingly arranged, and the length and width span can be adjusted by pulling and pulling to meet the positioning welding requirements of frames of different sizes.

[0028] Working principle:

[0029] According to the external dimensions of the skeleton on site, select the appropriate welding tooling shape, then slide and adjust the upper and lower slide bars to the appropriate length and width, use the top screw on the positioning table to push the slide bar downward to tighten and limit, and adjust the length and width of the welding tooling in this way until the inner frame size of the welding tooling matches the external dimensions of the skeleton. Place the profile used for the skeleton shape into the tooling, spot weld it, move the support slider to the horizontal and vertical support welding position of the skeleton, tighten it with bolts, then place the horizontal and vertical supports in the slider position, spot weld it, and after all the reinforcement supports are spot welded and fixed, remove the tooling to reinforce the skeleton.
