Description

Technical Field

[0001] This application relates to the field of pressure welding machine technology, specifically a pressure welding machine for steel grating. Background Technology

[0002] A pressure welding machine is a type of welding platform machinery that primarily employs a floating device to prevent the welding pressure from directly acting on the turntable, achieving precise positioning for hot-press welding and enabling precision welding. Pressure welding machines typically combine pressure and heat to join two or more metal workpieces together. This welding method produces strong weld joints and is commonly used for joining metal parts, pipes, welding wires, etc.

[0003] Patent CN221185071U discloses a double-sided welding machine for high-strength steel gratings. This machine, through the coordinated use of components such as support rods, limiting grooves, positioning blocks, and extension plates, effectively reduces the time spent disassembling and installing the lower welding seat. The lower welding seat can be replaced via a removal device without waiting for the welding machine to stop and cool down, effectively improving production efficiency and reducing the impact on welding production. Through the coordinated use of components such as worm gears, worm wheels, drive rods, and bearing plates, operators can easily adjust the angle of the lower welding seat, improving its adaptability to different welding needs and increasing work efficiency. However, the rotation angle for adjusting the lower welding seat by rotating a turntable and driving a series of components is limited, still requiring manual adjustment. This results in a low level of automation, a high proportion of labor costs, and reduced working time and efficiency of the welding machine. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a steel grating pressure welding machine, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this application provides the following technical solution: a steel grating pressure welding machine, comprising a machine body, a pressure welding mechanism for pressing and welding workpieces, and a fixing mechanism for clamping components for placing workpieces. The top of the machine body is provided with an adjustment mechanism for adjusting the angle of the components for placing workpieces. The adjustment mechanism includes a limiting plate and an arc-shaped groove. The limiting plate is disposed below the pressure welding mechanism, and the arc-shaped groove is opened inside the upper part of the machine body. The arc-shaped groove is slidably connected to one end of the limiting plate. The bottom of the pressure welding mechanism is fixedly connected to the left side of the top of the machine body, and the fixing mechanism is disposed inside the machine body.

[0008] By adopting the above technical solution, the limiting plate that is slidably connected to the arc groove can provide movable space for the rotation of the turntable, avoiding the situation where the turntable needs to be manually adjusted due to its small rotation angle.

[0009] Preferably, the adjustment mechanism further includes a placement slot and a lifting slot. The placement slot is located at the center of the top of the machine body, and the lifting slot is located at the bottom of the placement slot. An arc-shaped groove is formed on the upper part of the inner wall of the lifting slot, and a second motor is fixedly connected to the bottom of the lifting slot.

[0010] By adopting the above technical solution, the second motor in the lifting slot at the bottom of the slot can be used to provide power support for the operation of the adjustment mechanism.

[0011] Preferably, the adjustment mechanism further includes a vertical screw and a limiting groove. The bottom of the vertical screw is fixedly connected to the output shaft of the second motor. An internally threaded tube is threadedly connected to the side of the vertical screw. The lower left side of the internally threaded tube is fixedly connected to a limiting plate. The limiting groove is opened below the arc-shaped groove and is connected to the arc-shaped groove.

[0012] By adopting the above technical solution, the vertical screw can be rotated under the drive of the output shaft of the second motor. The rotation of the vertical screw drives the internal thread tube on one side of the limiting plate in the limiting groove to move up and down, thereby achieving the purpose of adjusting the height of the turntable. It also makes it easy for the lower pressure welding seat to be consistent with the height of the U-shaped plate after the angle adjustment is completed, and thus be fixed by the U-shaped plate.

[0013] Preferably, the adjustment mechanism further includes a turntable and a locking block. The bottom of the turntable is fixedly connected to the top of the internally threaded tube, and a locking groove is provided on the top of the turntable. The top of the locking block is fixedly connected to the bottom of the pressure welding mechanism, and the shape of the locking block is consistent with that of the locking groove.

[0014] By adopting the above technical solution, the slot on the top of the turntable and the contact of the card block can be used to facilitate the rotation of the turntable to drive the rotation of the lower pressure welding seat and adjust the angle of the lower pressure welding seat.

[0015] Preferably, the pressure welding mechanism includes a support frame and a cylinder. The bottom left side of the support frame is fixedly connected to the top left side of the machine body, the top of the cylinder is fixedly connected to the bottom right side of the support frame, and a pressure plate is fixedly connected to the bottom of the cylinder.

[0016] By adopting the above technical solution, the cylinder connected to the support frame can be used to move the pressure plate up and down, which facilitates the pressure welding work and the picking and placing of the workpieces that need to be pressure welded.

[0017] Preferably, the pressure welding mechanism further includes an upper pressure welding seat and a lower pressure welding seat, the top of the upper pressure welding seat being fixedly connected to the bottom of the pressure plate, and the bottom of the lower pressure welding seat being fixedly connected to the top of the clamping block.

[0018] By adopting the above technical solution, the workpiece placed inside the upper pressure welding seat can be pressed down by the upper pressure welding seat to achieve the purpose of welding the workpiece.

[0019] Preferably, the fixing mechanism includes a fixing box and a rotating hole. The fixing box is fixedly connected to the lower right side of the machine body. A first motor is fixedly connected to the right side of the inner wall of the fixing box. A bidirectional screw is fixedly connected to the output shaft of the first motor. The rotating hole is located on the lower right side of the machine body. The left side of the rotating hole is rotatably connected to one end of the bidirectional screw. A movable groove is provided at the top of the rotating hole.

[0020] By adopting the above technical solution, the output shaft of the first motor in the fixed box can be rotated to drive the bidirectional screw in the rotating hole at the bottom of the movable slot to rotate, thereby providing power support for the U-shaped plates to move towards or away from each other.

[0021] Preferably, the fixing mechanism further includes an internal threaded ring and a U-shaped plate. The inner wall of the internal threaded ring is threadedly connected to the surface of the bidirectional screw. A connecting rod is fixedly connected to the top of the internal threaded ring, and the bottom of the U-shaped plate is fixedly connected to the top of the connecting rod.

[0022] By adopting the above technical solution, the rotation of the bidirectional screw can drive the internal threaded ring in the movable groove to move. The movement of the internal threaded ring drives the connecting rod to move. The movement of the connecting rod drives the U-shaped plate to move towards each other until it fits against the side of the lower pressure welding seat, thus fixing the lower pressure welding seat.

[0023] (III) Beneficial Effects

[0024] This application provides a steel grating pressure welding machine. It has the following beneficial effects:

[0025] 1. This steel grating pressure welding machine, through the setting of an adjustment mechanism, has a second motor output shaft in the lifting groove rotating to drive a vertical screw to rotate. The rotation of the vertical screw drives the limiting plate on the side of the internal threaded tube to move upward in the limiting groove, and at the same time drives the turntable in the placement groove to move upward until the clamping block is engaged in the clamping slot. When the limiting plate moves into the arc groove, the rotation of the vertical screw drives the turntable at the top of the internal threaded tube to rotate and adjust the lower pressure welding seat to the target angle. This reduces the involvement of workers and labor costs, extends the pressure welding time, and improves the automation level and work efficiency of the pressure welding machine.

[0026] 2. This steel grating pressure welding machine, through the setting of a fixing mechanism, the rotation of the first motor output shaft in the fixing box drives the rotation of the bidirectional screw in the rotating hole. The rotation of the bidirectional screw drives the movement of the internal threaded ring at the bottom of the connecting rod in the movable groove. The movement of the internal threaded ring drives the movement of the connecting rod. The movement of the connecting rod drives the U-shaped plates to move towards each other to fix the lower pressure welding seat. This simplifies the parts and structure of the fixing components, reduces the production cost of the pressure welding machine, and improves the cost performance of the pressure welding machine.
