Description

Technical Field

[0001] The present application relates to the technical field of box bracket welding, and in particular to a triangle iron welding fixture for a box bracket. Background Art

[0002] The triangular iron box bracket is a metal used to support and fix the box. It is usually made of triangular iron and is used to support and fix various boxes. For example, the box distribution box commonly used in electrical equipment requires a triangular iron box to directly install and protect the distribution box.

[0003] Before welding the triangle, it is necessary to clean the oil, rust, oxide scale and other impurities on the welding part of the triangle box, place the triangle to be welded on the box according to the design requirements, and use a clamp or electric welding to preliminarily fix it to prevent displacement during the welding process.

[0004] Reference publication number CN220679855U, the subject name is a fixing device for welding an angle steel tripod. The device uses motor one and motor two to drive a pressure plate and a fixing block to fix the angle steel, thereby reducing the offset of the angle steel during welding, and uses a fixing mechanism to fix the outer part of the angle steel to increase the stability of the angle steel during welding.

[0005] According to the above technical solution, when performing box bracket type welding on the angle iron, the position of the welding machine is different due to the different boxes. When welding boxes of different sizes, it is necessary to fix triangles of different lengths. Therefore, the triangle iron needs to be repeatedly positioned when welding and fixing triangles of different lengths. When welding the box bracket, the staff is required to press the vertical triangle iron on the welded triangle iron base, and spot weld the middle position of the triangle iron that needs to be vertically welded and the welded triangle iron base. When welding the triangle iron that needs to be vertically welded, the welding of the triangle iron may be unstable due to the angle problem of the staff. Summary of the Invention

[0006] In view of this, the present application provides a triangle iron welding fixture for a box bracket, which aims to solve the problem of welding position offset when welding the triangle iron box bracket, and the need to readjust the positioning block on the welding plate when welding triangle irons of different lengths.

[0007] The present application provides a triangle welding fixture for a box bracket, which adopts the following technical solution, including a bracket and a rotating mechanism; a rotating flap is rotatably connected to the bracket, a first motor is slidably connected to the lateral side wall of the rotating flap, and a second motor is slidably connected to the longitudinal side wall of the rotating flap, and a rotating screw is fixedly connected to the output shafts of the first motor and the second motor, and the rotating screw is threadedly connected to a first clamping block at one end away from the first motor and the second motor, and the first motor and the second motor are both fixedly connected to the second clamping block, and the first clamping block and the second clamping block are both fixedly connected to an abutment baffle for abutting the outer wall of the triangle, and the first clamping block is used to follow the rotation of the first motor or the second motor to abut triangles of different lengths.

[0008] Through the precise control of the motor and the screw rod, the triangle iron can be positioned more accurately before welding, reducing welding errors and improving the quality of the welded joint.

[0009] Optionally, a connecting block is fixedly connected to the rotating flap, a connecting baffle is fixedly connected to the connecting block, and the connecting baffle is used to abut against the outer side wall of the triangle iron.

[0010] By being suitable for triangles of different lengths, the welding tooling required for triangles of a single length is reduced, thereby improving the versatility of the equipment. Through the precise control of the lead screw driven by the motor, the triangles can be moved to relative positions, ensuring that triangles of different lengths can be accurately aligned, thereby ensuring welding quality.

[0011] Optionally, a sliding rod is fixedly connected to the first clamping block and the second clamping block, a top corner clamping block is slidably connected to the intersection of the sliding rods, and a top corner clamping block is slidably connected at the top corner where the rotating flap is away from the connecting block, and the top corner clamping block is used to abut the welding part of the triangle iron.

[0014] Since the triangle iron may be deformed during the welding process, abutting the inner and outer walls of the triangle iron can help resist the thermal stress during welding and reduce the deformation of the triangle iron during welding. Support and abutment can ensure that the triangle iron maintains the correct position and shape during the welding process, thereby maintaining the dimensional accuracy of the welded structure.

[0015] Optionally, one end of the connecting plate close to the abutting block is rotatably connected to a downward connecting rod, and one end of the downward connecting rod away from the connecting plate is rotatably connected to a lower pressure plate, and a lower pressure roller is rotatably connected to the lower pressure plate.

[0019] The vertical triangles, perpendicular to the bottom triangle, create a more stable structure because they better distribute and withstand forces from all directions. This vertical arrangement ensures even load transfer, reduces local stress concentrations, and increases the overall load-bearing capacity of the frame.

[0020] Optionally, the rotating mechanism includes a rotating shaft fixedly connected to the side wall of the rotating flap, a rotating motor is fixedly connected to the bracket, and an output shaft of the rotating motor is fixedly connected to the rotating shaft.
