Description

Technical Field

[0001] The utility model relates to the technical field of metal structure welding jigs, in particular to a welding fixing mechanism for metal structure manufacturing. Background Art

[0002] Welding technology is required in the production and processing of metal structures. Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. When metal square tubes are connected to multiple square tubes, welding technology is usually required to weld the metal square tubes.

[0003] At present, when welding multiple metal square tubes outside a metal square tube, workers usually place the long metal square tube on the ground, and then hold the short metal square tube and press it on the surface of the long metal square tube for welding. This welding operation is affected by the workers' welding experience, which can easily cause the welding position of the short metal square tube on the surface of the long metal square tube to deviate. In addition, the operation of holding the metal square tube for a long time can easily cause fatigue of the workers' hands, which is not conducive to the batch welding of metal square tube structures. Therefore, we propose a welding fixing mechanism for metal structure manufacturing. Utility Model Content

[0004] The main purpose of the present utility model is to provide a welding fixing mechanism for metal structure manufacturing. By setting a fixing mechanism for welding and manufacturing metal structures such as metal square tubes, the fixing mechanism clamps and fixes the long metal square tube at the U-shaped main connector, and then cooperates with multiple U-shaped auxiliary connectors to clamp and fix multiple short metal square tubes, so that the short metal square tubes can be quickly fixed after being contacted and positioned with the long metal square tubes, ensuring that the short metal square tubes are not easily moved when welding the long metal square tubes, and after the short metal square tubes are vertically clamped and fixed, there is no need for workers to hold the short metal square tubes and weld them above the long metal square tubes. While reducing the fatigue of workers welding metal structures such as metal square tubes, the welding position accuracy between the metal square tubes can also be guaranteed in a positioning manner, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The U-shaped base is fixed on the top of the vertical seat plate of the U-shaped base, and the T-shaped bracket is slidably inserted into the plate groove of the U-shaped cover plate. The double-set frame rods of the T-shaped bracket are welded to the base plate surface of the U-shaped main seat, and the side pressure plates are welded on the outside of the vertical seat plate of the U-shaped main seat. A U-shaped bracket is provided on the outside of the vertical seat plate on the other side of the U-shaped base away from the side pressure plates. The U-shaped main seat and the U-shaped auxiliary seat are provided with spinning holes for rotating the spinning block at the convex bulges on the long seat edges of the U-shaped main seat and the U-shaped auxiliary seat.

[0008] By adopting the above technical solution, after the truncated cone-shaped handle block of the spinning block is welded with a threaded rod, the threaded rod can be screwed into the spinning hole to clamp the metal square tube placed in the U-shaped main socket and the U-shaped auxiliary socket.

[0009] Furthermore, a handle is welded between the upper surface of the cone disc and the rod body of the support column, and a threaded rod body for screwing into the support hole is provided at the top rod body of the support column;

[0010] By adopting the above technical solution, the handle welded between the cone disk and the push rod can be used as the position for turning the push rod, so that the threaded rod body can be screwed into the screw hole for connection after the push rod is rotated.

[0011] Furthermore, the short plate of the L-shaped pressing plate is stuck to the surface of the U-shaped base near the U-shaped groove, and the plate thickness of the L-shaped pressing plate is the same as the groove cavity height of the U-shaped groove;

[0012] By adopting the above technical solution, after the short plate of the L-shaped pressing plate is clamped on the inner wall surface of the U-shaped base, it can be ensured that the L-shaped pressing plate is firmly clamped into the U-shaped bar seat.

[0013] Furthermore, the U-shaped main connector has a cylindrical convex bulge protruding from the outside of the panel facing the side pressure plate, and the U-shaped auxiliary connector has a cylindrical convex bulge protruding from the outside of the panel facing away from the vertical connecting rod;

[0014] By adopting the above technical solution, the cylindrical convex parts of the U-shaped main seat and the U-shaped auxiliary seat are provided with spinning holes, which can be used to spin the spinning blocks to spin the metal square tubes in the seats themselves.

[0015] Furthermore, the U-shaped auxiliary seat is symmetrically welded with a vertical connecting rod on the back seat surface away from the vertical seat opening thereof, and the vertical connecting rod is symmetrically welded on the long plate surface of the L-shaped pressure plate, and the vertical connecting rod is abutted against the outside of the seat plate of the U-shaped base;

[0016] By adopting the above technical solution, the U-shaped auxiliary connector is connected by welding the L-shaped pressure plate with a vertical connecting rod, and then the vertical connecting rod can be placed outside the U-shaped base to provide stable support for the U-shaped auxiliary connector.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The utility model is provided with a fixing mechanism for welding and manufacturing metal structures such as metal square tubes. The fixing mechanism clamps and fixes the long metal square tube through a U-shaped main connector, and then cooperates with a plurality of U-shaped auxiliary connectors to clamp and fix a plurality of short metal square tubes. The short metal square tubes can be quickly fixed after being contacted and positioned with the long metal square tubes, ensuring that the short metal square tubes are not easily moved when being welded to the long metal square tubes.

[0019] Moreover, after the short metal square tube is fixed by the vertical clamp, workers do not need to hold the short metal square tube to weld it above the long metal square tube. While reducing the fatigue of workers welding metal structures such as metal square tubes, it can also ensure the accuracy of the welding position between the metal square tubes in a positioning manner.

[0025] The surface of the truncated cone-shaped handle of the spinning block 11 is welded with a threaded rod, and the threaded rod of the spinning block 11 is screwed into the spinning hole 10;

[0026] By adopting the above technical solution, after the truncated cone-shaped handle block of the spinning block 11 is welded with a threaded rod, the threaded rod can be screwed into the spinning hole 10 to clamp the metal square tube placed in the U-shaped main socket 4 and the U-shaped auxiliary socket 9.

[0027] A handle 15 is welded between the upper surface of the cone 14 and the rod of the support column 13, and a threaded rod for screwing into the support hole 12 is provided at the top of the support column 13.

[0028] By adopting the above technical solution, the handle 15 welded between the cone disk 14 and the push rod 13 can be used as the position of the push rod 13, so that the push rod 13 can be rotated and connected to the screw hole 12 by screwing the threaded rod body.

[0029] The short plate of the L-shaped pressing plate 7 is stuck to the surface of the U-shaped base 1 near the U-shaped groove 6, and the thickness of the L-shaped pressing plate 7 is the same as the height of the groove cavity of the U-shaped groove 6;

[0030] By adopting the above technical solution, after the short plate of the L-shaped pressing plate 7 is clamped on the inner wall surface of the U-shaped base 1, it can be ensured that the L-shaped pressing plate 7 is firmly clamped into the U-shaped bar seat 6.

When welding metal structures such as metal square tubes, the fixing mechanism of the present invention can be used. After the fixing structure of the present invention is pressed on the ground with the U-shaped base 1 and the base plate 16 to obtain support, the L-shaped pressing plate 7 can slide into the U-shaped groove 6 of the U-shaped base 1 for clamping, and then the T-shaped bracket 3 under the U-shaped main seat 4 can slide into the U-shaped groove of the U-shaped cover 2, so that the U-shaped main seat 4 is pressed on the surface of the U-shaped cover 2, and then the worker puts the long metal square tube After being placed in the U-shaped main seat 4, use the spinning block 11 to screw it into the seat from the spinning hole 10 of the U-shaped main seat 4, and clamp the long metal square tube in the U-shaped main seat 4. Then, screw the column 13 down at the screw hole 12 of the side pressure plate 5, so that the column 13 presses the cone disk 14 on the surface of the base plate 16 to support the side pressure plate 5 and the U-shaped main seat 4, so that the U-shaped main seat 4 is not easy to move. Then slide the L-shaped pressure plate 7 to move the U-shaped auxiliary seat 9 to the position where the long metal square tube needs to be welded, and use a short metal square tube to pass through the U-shaped auxiliary seat 9 and press it down.

Workers can install multiple L-shaped pressure plates 7 with U-shaped sub-seats 9 at the U-shaped groove to fix multiple sections of short metal tubes. Then, workers can fix the long metal square tube and the short metal square tube in the fixed position. After the welding of the square tube metal structure is completed, the spinning blocks 11 at the U-shaped main joint 4 and the U-shaped auxiliary joint 9 can be unscrewed, and then the long metal square tube in the U-shaped main joint 4 can be pulled up to leave the U-shaped main joint 4, and the metal square tube can be stretched sideways to make the short metal square tube leave the U-shaped auxiliary joint 9.
