Technical Field
[0001] This utility model relates to the field of profile welding technology, and in particular to a profile welding fixture. Background Technology
[0002] In steel structure manufacturing, machining, and building frame assembly, profile welding is one of the core processes. The welding quality directly determines the strength, dimensional accuracy, and service life of structural components, and the positioning of profiles before welding is a crucial factor affecting the welding quality.
[0003] Chinese patent application CN202322646034.5 discloses a positioning component and aluminum alloy window profile welding equipment, including: a worktable, a clamping mechanism, a fixing mechanism, a profile, and a welding mechanism. A fixing block is provided on the top of the worktable, and a first hydraulic pump is mounted on the side of the fixing block. A right-angle caliper is provided at one end of the first hydraulic pump. Two clamping mechanisms and a fixing mechanism are respectively provided on the two adjacent sides of the worktable where the fixing block is located. The profile is located inside the clamping mechanism and at the bottom of the fixing mechanism. A cavity is provided at the junction of the profile and the bottom of the worktable. The profile is positioned by the right-angle caliper in conjunction with the fixing and clamping mechanisms, which can prevent the aluminum alloy window frame from shifting during welding, thereby improving the production quality and efficiency of aluminum alloy windows. However, in this structure, a cavity is provided to ensure welding at the profile welding point, which causes the welding end of the profile to be suspended, easily causing loosening during welding and affecting the welding quality. Therefore, this application proposes a profile welding fixture to solve the above problems. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a profile welding fixture.
[0005] To solve the above-mentioned technical problems, the present invention includes a worktable plate, wherein the worktable plate is provided with a strip-shaped through groove;

[0007] A material support frame includes a positioning plate and support strips. The positioning plate has a groove that overlaps with the strip-shaped through groove. Symmetrical positioning strips are provided on both sides of the groove. There are two support strips, which extend along the length of the two positioning strips and are fixed to the positioning plate.
[0008] An angle positioning component is fixed to a positioning plate and is located at one end of a groove.
[0009] Preferably, the clamping assembly, the material support frame, and the corner positioning component are all in two sets and are symmetrically arranged at the center position of the strip through groove along its length.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All directional indicators (such as up, down, left, right, front, back, etc.) in the present utility model are only used to explain the relative positional relationship and movement of each component in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indicator will also change accordingly.
[0026] like Figure 1-7 As shown, this embodiment provides a profile welding fixture, including a worktable 1, which serves as the carrier and installation foundation of the entire fixture system. A strip groove 2 is provided on the worktable 1. A clamping assembly 3, a material support frame 4, and a corner positioning component 5 are installed on the worktable 1. The clamping assembly 3 is divided into two groups, each group consisting of two components, which are symmetrically located on both sides of the strip groove 2. The clamping assembly 3 is used to clamp and fix the welding end of the profile 6. The material support frame 4 includes a positioning plate 41 and a support strip 42. The positioning plate 41 has a groove 43 that coincides with the center line of the strip groove 2. Symmetrical positioning strips 44 are provided on both sides of the groove 43. There are two support strips 42, which extend along the length of the two positioning strips 44 and are fixed to the positioning plate 41. The corner positioning component 5 is fixed on the positioning plate 41 and is located at one end of the groove 43. The corner positioning component 5 is fixed at the end of the two positioning strips 44 that are close to each other.
[0027] Furthermore, the clamping assembly 3, the material support frame 4, and the corner positioning component 5 are all in two sets and symmetrically arranged at the center position of the length direction of the strip through groove 2. The number of clamping assemblies 3 is the same as the number of profiles 6. When welding the rectangular frame structure composed of four profiles 6, the corner profiles 6 components can be welded at the same time, thereby improving the welding efficiency.
[0028] like Figure 4 , 5As shown, in this example, the clamping assembly 3 includes a cylinder 31, a clamping seat 32, and a clamping block 33. The telescopic end of the cylinder 31 passes through the clamping seat 32, which is connected to the clamping block 33. The clamping block 33 is arranged along the length of the profile 6. The cylinder 31 drives the clamping block 33 to clamp the profile 6. A connecting plate 34 is fixedly connected to the telescopic end of the cylinder 31. Both the end face of the connecting plate 34 and the end face of the clamping block 33 are provided with wedge-shaped strips 35. The bottom surface of the clamping seat 32 is provided with a wedge-shaped groove 36. The wedge strip 35 is placed in the wedge groove 36, and the clamping seat 32 is fixedly connected to the connecting plate 34 by screws. The end of the pressure block 33 near the welding position of the profile 6 has a triangular structure. The cylinder 31 is fixed to the worktable 1 through the cylinder seat. The cylinder 31 drives the clamping seat 32 to rise and fall, so that the pressure block 33 presses and fixes the profile 6. At the same time, the pressure block 33 and the clamping seat 32 can slide along the wedge groove 36 to adapt to changes in the size and position of the workpiece.
[0029] like Figure 6 , 7 As shown, further, the corner positioning component 5 includes a positioning seat 51, which is fixed on the positioning plate 41. A positioning tongue 52 is slidably provided inside the positioning seat 51, and a locking screw for locking the positioning tongue 52 is threaded onto the positioning seat 51. The end of the positioning tongue is provided with a corner groove 53. The included angle between the two positioning strips 44 is consistent with the angle of the corner groove 53, both being 90°. The upper surface of the support strip 42 and the upper surface of the positioning plate 41 are located on the same plane. When the two profiles 6 are welded, the welding ends of the two profiles 6 are 45° beveled, and the outer side of the profile 6 is in contact with the positioning strip 44, ensuring that the adjacent sides of the two profiles 6 form a 90° angle. At the same time, the positioning tongue 52 moves from the positioning seat 51. The 90° corner groove 53 of the positioning tongue 52 extends out from the middle and can just abut against the corner formed by the beveled surfaces of the two profiles 6 after they are fitted together, so that the sharp corners of the two profiles 6 are aligned. Moreover, the profile 6 has a relatively thin wall thickness. During processing and transportation, the opening edge of the material may bend inward, causing unevenness defects after the profile 6 is welded. The tooling is required to stretch the weld joint to ensure the flatness of the weld surface. After the sharp corner of the profile 6 is inserted into the corner groove 53 of the positioning tongue 52, the upper surface of the positioning seat 51 just flattens the weld surface on the profile 6. The lower sharp corner plugs into the gap under the positioning seat 51, so that the weld surface of the lower sharp corner is flush, thereby ensuring the flatness of the weld surface and improving the welding quality.
[0030] Its working principle is as follows: the positioning strips 44 on both sides of the positioning plate 41, together with the corner positioning piece 5, position the two profiles 6 to be welded, and the clamping assembly 3 clamps and fixes the profiles 6. At the same time, the strip groove 43 and the strip through groove 2 are used to facilitate the welding structure to weld the two profiles 6 to be welded. This can avoid the welding part of the profile 6 being suspended, improve the stability of the positioning of the profile 6, and provide stable conditions for the welding of the profile 6. The overall structure is simple and reliable, and can greatly improve the automated welding efficiency of the profile 6 assembly.
