Description

Technical Field

[0001] This utility model relates to the field of steel structure welding positioning fixtures, and in particular to steel structure welding auxiliary positioning fixtures that facilitate angle adjustment. Background Technology

[0002] In the field of steel structure manufacturing and processing, welding is a crucial connection process. Its quality and efficiency directly affect the performance and production cycle of steel structure products. Traditional welding fixtures mostly adopt fixed structures with limited clamping spacing and angle adjustment capabilities. In actual operation, operators often need to use auxiliary tools such as pads and jacks to adjust the angle, which is not only time-consuming and labor-intensive, but also difficult to guarantee adjustment accuracy. Especially when performing multi-angle and multi-position welding, the workpiece is prone to displacement due to insufficient clamping force or unstable positioning, which seriously affects welding accuracy and structural strength. Therefore, it is necessary to improve the above-mentioned problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary positioning fixture for steel structure welding that facilitates angle adjustment.

A sliding rod is slidably sleeved on the second lead screw. Sliding grooves are opened on both sides of the mounting frame, and the two ends of the sliding rod pass through the sliding grooves and extend out of the mounting frame.

[0006] Preferably, the sliding rod is provided with a limiting plate at the outer wall of the sliding groove, and a connecting plate is rotatably provided at one end of the limiting plate. The other end of the connecting plate is hinged to a second hinge seat, which is fixedly connected to the outer walls of both sides of the clamping plate.

[0007] Preferably, the top surfaces of the two fixed clamping seats are provided with hexagonal socket bolts, and the top surfaces of the clamping plate are provided with fixing holes corresponding to the hexagonal socket bolts at both ends.

[0008] Preferably, one end of the second lead screw is provided with a rotating handle, and one end of the first lead screw passes through the outer wall of the clamp plate and is fixedly provided with a knob.

[0009] Preferably, each of the two movable clamping seats has a support platform on its opposite surface.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model facilitates the adjustment of the clamping distance by sliding the two first lead screws with the movable clamping seat, thereby improving the adaptability and clamping efficiency of irregular steel components; combined with the linkage control of the second lead screw and the sliding rod in the tilting assembly, the high precision and strong self-locking characteristics of the lead screw transmission are utilized to achieve stepless and precise adjustment of the tilt angle of the clamping plate, and the force arm transmission between the connecting plate and the hinge seat ensures the structural stability after the angle adjustment; furthermore, the internal hexagonal bolt locking design of the fixed clamping seat enhances the torsional strength of the clamping end, and together with the support platform of the movable clamping seat, a three-point force structure is formed, which effectively suppresses the workpiece displacement caused by welding vibration, and finally solves the problems of inconvenient angle adjustment and easy positioning deviation of traditional welding fixtures, thereby improving welding quality and operational safety.

[0017] 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: See Figure 1-4 The steel structure welding auxiliary positioning fixture of this utility model, which facilitates angle adjustment, includes a clamping plate 1. Two first lead screws 2 are symmetrically arranged at both ends of the clamping plate 1. A partition for supporting the first lead screws 2 is provided in the middle of the clamping plate 1. Movable clamping seats 3 are movably sleeved on both first lead screws 2. Two fixed clamping seats 4 are symmetrically arranged at both ends of the top surface of the clamping plate 1. An inclined assembly is connected to the bottom surface of the clamping plate 1. The clamping plate 1 provides the basic support structure for the entire fixture. The arrangement of the first lead screws 2 allows the movable clamping seats 3 to move along the lead screws. The movable clamping seats 3 can be flexibly adjusted by rotating the first lead screws 2. The position of the clamping seat 3 facilitates the clamping and fixing of steel structures of different sizes. The fixed clamping seat 4 cooperates with the movable clamping seat 3 to further enhance the clamping stability of the steel structure. The partition helps to separate and position different steel structure components. The tilting component provides the possibility for subsequent adjustment of the tilt angle of the clamping plate 1, which facilitates multi-angle positioning during steel structure welding. The tilting component includes a mounting plate 5. Two first hinge seats are symmetrically provided on both sides of one end of the mounting plate 5. Both first hinge seats are rotatably hinged to the clamping plate 1. The other end of the mounting plate 5 is provided with a mounting frame 6, in which a second... The second lead screw 7 is slidably fitted with a sliding rod 8. Sliding grooves are provided on both sides of the mounting frame 6. The two ends of the sliding rod 8 pass through the sliding grooves and extend out of the mounting frame 6. The mounting plate 5 serves as the basic mounting structure for the tilting assembly. It is rotatably hinged to the clamping plate 1 via the first hinge seat, providing a fulcrum for the tilting of the clamping plate 1. The mounting frame 6 provides installation space and a movement track for the second lead screw 7 and the sliding rod 8. Rotating the second lead screw 7 allows the sliding rod 8 to slide along the sliding groove, thereby causing the clamping plate 1 to rotate around the first hinge seat, achieving adjustment of the tilt angle of the clamping plate 1 to meet different tilting requirements during steel structure welding. To meet the positioning requirements at the oblique angle, a limiting plate is provided on the outer wall of the sliding groove for the sliding rod 8. One end of the connecting plate 12 is rotatably mounted on the limiting plate, and the other end of the connecting plate 12 is hinged to a second hinge seat 11. The second hinge seat 11 is fixedly connected to the outer walls of both sides of the clamping plate 1. The limiting plate can prevent the sliding rod 8 from coming out of the sliding groove, ensuring the stability of the structure. The connecting plate 12 connects the sliding rod 8 and the clamping plate 1. When the sliding rod 8 slides under the drive of the second lead screw 7, the motion is transmitted to the clamping plate 1 through the connecting plate 12, so that the clamping plate 1 can rotate smoothly around the first hinge seat, thereby achieving precise adjustment of the tilt angle.

[0019] In this utility model, the top surfaces of the two fixed clamping seats 4 are provided with hexagon socket head cap screws 10, and the top surfaces of the clamping plate 1 are provided with fixing holes corresponding to the hexagon socket head cap screws 10. The hexagon socket head cap screws 10 cooperate with the fixing holes to firmly fix the fixed clamping seats 4 on the clamping plate 1, preventing the fixed clamping seats 4 from shifting during the welding process, thereby ensuring the clamping and positioning effect of the steel structure and improving the welding accuracy and quality. One end of the second lead screw 7 is provided with a rotating handle 9, and one end of the first lead screw 2 passes through the outer wall of the clamping plate 1 and is fixed with a knob. The handle 9 allows the operator to manually rotate the second lead screw 7 to adjust the tilt angle of the clamp plate 1, making operation simple and convenient. The knob allows the operator to rotate the first lead screw 2 to flexibly adjust the position of the movable clamping seat 3, improving the convenience of tooling use. Both movable clamping seats 3 have support platforms on their opposite surfaces, which can provide additional support for the steel structure, making the steel structure more stable when clamped and preventing it from shaking or shifting due to gravity or external forces. This further improves the positioning effect of the steel structure and helps to ensure welding quality.

[0020] Working principle: When using this utility model, the steel structure workpiece to be welded is first placed on the fixture plate 1. The knob at one end of the first lead screw 2 is rotated, and the movable clamping seat 3 moves along the first lead screw 2, cooperating with the fixed clamping seat 4 to clamp the workpiece. If it is necessary to adjust the tilt angle of the workpiece to meet the welding requirements, the operator rotates the rotating handle 9 at one end of the second lead screw 7. The rotation of the second lead screw 7 causes the sliding rod 8 to slide along the sliding grooves on both sides of the mounting frame 6. The limiting plate prevents the sliding rod 8 from coming off. As the sliding rod 8 slides, the connecting plate 12 rotatably connected to it moves. The connecting plate 12 is fixed to the outer walls on both sides of the fixture plate 1 through the second hinge seat 11, and the fixture plate 1 is rotatably hinged through the first hinge seat. Therefore, the movement of the connecting plate 12 drives the fixture plate 1 to rotate around the first hinge seat, realizing the adjustment of the tilt angle of the entire fixture plate 1 and the steel structure workpiece clamped on it.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
