Description

Technical Field

[0001] This utility model relates to the field of steel structure welding technology, specifically a steel structure welding fixture. Background Technology

[0002] In the welding process of steel structures, the use of fixtures is crucial. However, existing fixtures still have many problems, which not only affect production efficiency but also increase the production costs of enterprises. Therefore, it is particularly important to develop a new type of steel structure welding fixture.

[0003] Referring to a steel structure welding fixture with announcement number CN220679860U, it includes a fixture body, which includes a base. A support seat and a fixed seat are welded to the base. A movable seat is movably mounted on the top of the fixed seat and the support seat. A lifting mechanism is fixedly mounted on the movable seat. A fixed frame is welded to the bottom of the movable seat. Both the support seat and the fixed seat have fixed slots. The fixed frame is movably mounted inside the fixed slots. The support seat has slots. This steel structure welding fixture allows for direct vertical compression of the workpiece when its width is smaller than the pressing seat. Furthermore, for workpieces of different shapes, a displacement mechanism can be used in conjunction with a clamping plate to clamp and fix the workpiece in different directions. As can be seen from the above, while this fixture can be effectively used for clamping and welding steel structural components, it is generally not convenient to adjust the spacing between the clamping components, making it difficult to clamp and fix steel structural components of different lengths, thus exhibiting certain limitations. Utility Model Content

[0004] The purpose of this utility model is to provide a steel structure welding fixture to solve the problem mentioned in the background art that although the fixture can be used well to clamp and weld steel structural components, it is usually not convenient to adjust the spacing between the clamping parts, and therefore it is not easy to clamp and fix steel structural components of different lengths, which has certain limitations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel structure welding fixture, including a frame, a placement platform on the inner side of the frame, a first side connecting seat on one side of the top of the placement platform, a second side connecting seat on the other side of the top of the placement platform, a base on the top of the placement platform on both the second side connecting seat and the first side connecting seat, a sliding guide mechanism on both sides of the top of the base, a bearing plate on the top of the base, the bottom end of the bearing plate being connected to the sliding guide mechanism, a linear drive mechanism mounted on one side of the top of the base via a bracket, the linear drive mechanism being connected to the bearing plate via a connecting frame, and support legs installed at the corner positions of the bottom of the frame.

[0006] Preferably, the sliding guide mechanism includes a guide rail and a rail base, with the top of the guide rail slidably connected to the rail base and the bottom end of the bearing plate connected to the top end of the rail base.

[0007] Preferably, the linear drive mechanism is an electric push rod, one end of which is provided with a connecting frame, and the end of the connecting frame away from the electric push rod is connected to the outer wall of the support plate.

[0008] Preferably, a bearing seat is provided at the top of the frame on one side of the first side connecting seat. The inner wall of the bearing seat is connected to the outer wall of the first side connecting seat through a rotating shaft. The end of the rotating shaft away from the first side connecting seat is rotatably connected to the inner wall of the bearing seat. The rotating shaft is provided to connect the bearing seat and the first side connecting seat.

[0009] Preferably, a rotary drive mechanism is mounted on the top of the frame on one side of the second side connector via a bracket. One end of the rotary drive mechanism is connected to the outer wall of the second side connector. The rotary drive mechanism is configured to drive the placement table to rotate via the second side connector.

[0010] More preferably, the rotary drive mechanism is a geared motor, a servo motor, or a stepper motor.

[0011] Preferably, an L-shaped clamp is provided at the center of the top of the bearing plate, and a first rubber clamp is provided at the bottom of the L-shaped clamp. The first rubber clamp is provided to cooperate with the second rubber clamp to clamp and fix the steel structure.

[0012] Preferably, a nut seat is provided on the inner wall of the upper end of the L-shaped clamp, and a screw is installed on the internal thread of the nut seat. The top end of the screw extends to the outside of the nut seat, and the bottom end of the screw extends to the outside of the nut seat and is rotatably mounted with a second rubber clamp. The second rubber clamp is provided to cooperate with the first rubber clamp to clamp and fix the steel structure.

[0013] Preferably, the outer wall of the L-shaped clamp is provided with a sliding groove, one end of which extends to the inner side of the L-shaped clamp. A slider is slidably connected to one side of the inner side of the L-shaped clamp, one end of which extends to the outside of the sliding groove and is connected to the inner wall of the second rubber clamp. The slider and the sliding groove are configured to limit the movement range of the second rubber clamp.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the steel structure welding fixture can not only clamp and fix steel structural parts of different lengths to improve the applicability of the fixture, but also achieve the purpose of easy and quick clamping of steel structural parts, and it is easy to perform welding operations on steel structural parts at a specified angle.

[0015] (1) The bearing plate is driven to move horizontally by an electric push rod, so that the bearing plate drives the rail seat to slide on the top of the guide rail, so that the bearing plate drives the L-shaped clamp to move horizontally smoothly. Then, the distance between the two L-shaped clamps can be adjusted according to the length of the steel structure to clamp and fix steel structure with different lengths, thereby improving the applicability of the clamp.

[0016] (2) By placing both ends of the steel structure on the top of the two first rubber clamps, and then turning the screw, the screw rotates inside the nut seat and slides down, so that the screw drives the second rubber clamp to move down and contact the upper surface of the steel structure. The second rubber clamp, together with the first rubber clamp, can clamp and fix the two ends of the steel structure, thereby achieving the purpose of easy and quick clamping of the steel structure.

[0017] (3) By starting the rotary drive mechanism, the placement table can be driven to rotate slightly via the second side connecting seat. At the same time, the placement table drives the rotating shaft to rotate on the inner wall of the bearing seat via the first side connecting seat. This allows the angle of the steel structure held above the placement table to be tilted and adjusted, making it easier to perform welding operations on the steel structure at a specified tilt angle.
