Description

Technical Field

[0001] This utility model belongs to the field of auxiliary tooling technology for table frame welding, and in particular relates to a table steel frame welding fixture. Background Technology

[0002] Welding is a critical process in the manufacturing of table steel frames. Traditional welding methods often rely on manual positioning and handheld clamps for fixing, which is not only inefficient but also makes it difficult to ensure the relative positional accuracy between multiple components to be welded (such as support legs, connecting beams, baffles, and mounting bases). Especially for steel frames with complex angles and spatial structures, such as table frames containing L-shaped mounting bases and multiple connecting beams, manual positioning is prone to errors, leading to deformation and dimensional inaccuracies in the welded steel frame, affecting product quality and subsequent assembly. Utility Model Content

[0003] The purpose of this utility model is to provide a table steel frame welding fixture, which fixes the support legs of the table steel frame by inserting sleeves, and provides convex support parts A, B and C on the support plate for supporting the baffle, connecting beam A and connecting beam B respectively, thus solving the problems mentioned in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a welding fixture for a table steel frame. The table steel frame includes two parallel support legs, with a connecting beam A and a baffle connecting the two support legs. Each end of the two support legs is pivotally connected to an L-shaped mounting seat, and a connecting beam B connects the two mounting seats. The two mounting seats are respectively fixed to the bottom sides of the tabletop. The welding fixture includes a base, with inserts on both sides of the base. One side of each insert is threaded with an adjusting bolt, the end of which abuts against a clamping plate located inside the insert. Through the inserts on both sides of the base and the adjustable clamping plate, the two support legs of the table steel frame can be reliably clamped and fixed, providing a stable foundation for subsequent welding operations.

[0005] Furthermore, the clamp is provided with a guide rod that passes through the insert.

[0006] Furthermore, it also includes a guide rod disposed between the two inserts, one end of which is fixed to a fixed base A and the other end to a fixed base B; sliding seats are fitted on the two guide rods, and a support plate is disposed on the sliding seat. One side of the support plate is provided with, from bottom to top, a convex support portion A, a convex support portion B, and a convex support portion C for supporting the baffle, connecting beam A, and connecting beam B, respectively; the provision of convex support portions A, B, and C facilitates precise positioning and effective support of multiple transverse components in the middle of the steel frame during welding, ensuring the accuracy of the relative positions of each component before welding.

[0007] Furthermore, a telescopic push rod A, whose output end is connected to the sliding seat, is fixed on one side of the fixed base B.

[0008] Furthermore, a telescopic push rod B is fixed to the other side of the support plate. The output end of the telescopic push rod B is connected to a movable beam. The two ends of the movable beam are respectively connected to connecting rods. One side of the connecting rod is provided with pressure rods A, B, and C from bottom to top, which are used to clamp the baffle, connecting beam A, and connecting beam B, respectively. By driving the movable beam and connecting rods through the telescopic push rod B, the pressure rods A, B, and C are driven to move, which can apply a clamping force to the positioned baffle, connecting beam A, and connecting beam B from the other side, realizing bidirectional clamping, effectively preventing the components from shifting during the welding process, and ensuring the welding quality.

[0009] Furthermore, the inner wall surface of the connecting rod and the side end face of the support plate are provided with guide structures to ensure that the movement trajectory of the clamping mechanism is accurate during operation and will not deviate, so that the clamping force is applied evenly.

[0010] Furthermore, the insert is tilted and fixed on the base, and the tilt angle of the insert matches the actual posture of the support leg in the table steel frame, which facilitates the welding of the baffle, connecting beam A and connecting beam B.

[0011] This utility model has the following beneficial effects: This utility model, through the inserts and adjustable clamps on both sides of the base, can reliably clamp and fix the two support legs of the table steel frame. The convex support parts A, B and C facilitate the precise positioning and effective support of multiple transverse components in the middle of the steel frame during welding, thereby improving the overall positional accuracy of each component during welding.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-2 As shown, this utility model is a table steel frame welding fixture, which can weld table steel frames similar to / shaped as provided below. The table steel frame includes two parallel support legs 2, with a connecting beam A22 and a baffle 23 connecting the two support legs 2; each end of the two support legs 2 is pivotally connected to an L-shaped mounting seat 21, and a connecting beam B24 connects the two mounting seats 21; in the installed state, the two mounting seats 21 are respectively fixed to the two ends of the bottom side of the table board. The welding fixture includes a base 1. On both sides of the base 1, there are sockets 19 for inserting support legs 2. One side of the socket 19 is threaded with an adjusting bolt 191. The end of the adjusting bolt 191 abuts against a clamp plate. The clamp plate is located inside the socket 19. Two guide rods 192 are provided on the clamp plate and move through the socket 19. The socket 19 is fixed at an angle on the base 1.

[0017] During use, to facilitate the welding of the baffle 23, connecting beam A22, and connecting beam B24 between the two support legs 2; for example Figure 1-4 A pair of guide rods 13 are provided between the two inserts 19. One end of the guide rod 13 is fixed to the fixed seat A11, and the other end is fixed to the fixed seat B12. A sliding seat 15 is provided on the two guide rods 13. A telescopic push rod A14 with its output end connected to the sliding seat 15 is fixed on one side of the fixed seat B12. A support plate 16 is provided on the sliding seat 15. One side of the support plate 16 is provided with convex support parts A161, B162, and C163 from bottom to top, which are used to support the baffle 23, the connecting beam A22, and the connecting beam B24, respectively. In use, the baffle 23, the connecting beam A22, and the connecting beam B24 are supported and placed on the convex support parts A161, B162, and C163, respectively. The telescopic push rod A14 is extended to move the support plate 16 to the designated position. At this time, the baffle 23, the connecting beam A22, and the connecting beam B24 move to the corresponding positions and can be welded with a welding gun.

[0018] To prevent the baffle 23, connecting beam A22, and connecting beam B24 from swaying on the support plate 16 during movement, a telescopic push rod B17 is fixed on the other side of the support plate 16. The output end of the telescopic push rod B17 is connected to a movable beam 184, and the two ends of the movable beam 184 are connected to connecting rods 18 respectively. One side of the connecting rod 18 is provided with pressure rods A181, B182, and C183 from bottom to top, which are used to clamp the baffle 23, connecting beam A22, and connecting beam B24 respectively.

Then, the telescopic push rod B17 is controlled to retract, and the pressure rods A181, B182 and C183 are controlled to abut against the baffle 23, connecting beam A22 and connecting beam B24 respectively. Activate telescopic push rod A14 to push sliding seat 15 along light rod 13 to the first predetermined working position; Tighten the adjusting bolt 191 to push the clamp plate inside the insert 19 to move, thereby pressing the support leg 2 tightly against the clamp plate from the inside, and the inner wall of the support leg 2 against the end of the baffle 23, the connecting beam A22 and the connecting beam B24; Welding is performed manually or by a robot. After welding is completed, the telescopic push rod B17 is extended, and then the telescopic push rod A14 is retracted to move the sliding seat 15 along the light rod 13 to the second predetermined working position. The welded table frame can then be removed.

[0021] In the above, control buttons can be used to control the extension and retraction of telescopic push rods A14 and B17.

[0022] To achieve automated and intelligent production, a miniature clamping cylinder can be used to replace the adjusting bolt 191. The system also includes a processor connected to the miniature clamping cylinder, telescopic push rod A14, and telescopic push rod B17. The processor is connected to the welding robot and controls the corresponding actions.
