Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a heating welding device with a protective structure. Background Art

[0002] 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. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound, etc. When welding, welding equipment is often required.

[0003] Among them, a welding device with a protective structure disclosed in application number CN202221264913.0 is also an increasingly mature technology. The relative position between the slide rail and the weld body is adjusted through the adaptive movement of the slide rail and the weld body, and the screw rod is rotated to make the screw rod threadedly transmit the slide rail, adjust the height position of the slide rail, and drive the pallet at the side end of the slide rail to synchronously move, and adjust the pallet to a suitable position. The pallet and the clip are movably connected to each other. At the same time, a threaded rod is horizontally penetrated through the middle part of the clip near the middle part of the pallet, and the clip and the threaded rod are threadedly connected to each other. The threaded rod is rotated to adjust the horizontal position of the clip, and the clip is close to the end wall of the pallet, and the parts to be welded carried between the pallet and the clip are clamped and locked, and the parts to be welded are firmly placed for adaptive welding.

[0004] A welding device with a protective function disclosed in CN202322596418.0 is an increasingly mature technology. It is equipped with a positioning device. When some cylindrical or tubular air-conditioning accessories need to be welded, the fixed sleeve and the rotating sleeve can quickly position the cylindrical or tubular air-conditioning accessories, which is convenient for welding cylindrical or tubular air-conditioning accessories and avoids the situation where the air-conditioning accessories are easy to slide. The positioning process is simple, which improves the efficiency of welding and processing of air-conditioning accessories.

[0005] Based on this, I agree with the advantages of the above products, but there are still the following defects:

[0006] Both welding devices cannot be rotated during operation, which limits the working angle of the workers during welding, reduces production efficiency, and prolongs the welding time. In addition, high-temperature sparks will be generated during the welding operation, which may cause harm to the workers' bodies and secondly, cause serious harm to the workers' eyes. Utility Model Content

[0007] The utility model aims to provide a heating welding device with a protective structure to solve the problems proposed in the background art that the welding device cannot be rotated to reduce production efficiency and that high-temperature sparks will be generated during operation, causing harm to the body and eyes of the workers.

[0008] The embodiment of the utility model provides a heating welding device with a protective structure, comprising a work table, an L-shaped plate is arranged at one end of the top of the work table, a rotating device is arranged horizontally near the bottom of the L-shaped plate, and a protective device is arranged on the top of the work table;

[0010] The protective device includes a motor arranged on the front side of the work table, the output end of the motor is connected to the forward and reverse screw rods, the forward and reverse screw rods are located in the middle of the work table, and the work table is provided with symmetrical movable grooves on the top of the forward and reverse screw rods. The interior of the movable grooves is movably connected with square blocks and penetrates the forward and reverse screw rods, and the tops of the square blocks are fixedly connected with protective plates.

[0011] In this embodiment, the motor drives the rotating shaft and the mounting frame to rotate synchronously, and the screws and nuts cooperate to facilitate the opening and locking of the upper arc block, so that the parts to be welded can be placed in the internal clamping of the upper arc block and the lower arc block. The mounting frame then drives the clamped welded parts to rotate, thereby improving the work efficiency of the staff. The motor drives the forward and reverse screws to rotate, and the forward and reverse screws drive the square blocks to move closer to or away from each other along the inside of the moving groove. The square blocks drive the protective plates to move synchronously, thereby combining and separating the protective plates to avoid damage to the body and eyes of the staff.

[0012] In one embodiment of the utility model, a telescopic rod is arranged in the middle of the bottom end of the top of the L-shaped plate, the bottom of the telescopic rod is fixedly connected to a mounting plate, a welding head is arranged at the bottom of the mounting plate, a convex plate is arranged on one side of the mounting plate close to the L-shaped plate, a guide groove is opened on the side wall of the L-shaped plate, a guide rod is arranged inside the guide groove, and the guide rod passes through the convex plate.

[0013] In this solution, the mounting plate and the welding head at the bottom are lifted or lowered by the telescopic rod. When the mounting plate is lifted or lowered, the convex plate is guided and moved along the guide rod inside the guide groove to ensure that the welding head maintains a stable position and direction during operation while avoiding deviation or jitter.

[0014] In an implementation manner of the utility model, a thread groove is provided at the bottom of the threaded rod, a threaded protrusion is provided at the top of the pressing plate, and the pressing plate is movably mounted at the bottom of the threaded rod.

[0023] The motor drives the positive and negative screws to rotate, and the positive and negative screws drive the square blocks to move closer to or away from each other along the inside of the moving groove. The square blocks drive the protective plates to move synchronously, so that the protective plates can be combined and separated to avoid damage to the body and eyes of the staff. The motor drives the rotating shaft and the mounting frame to rotate synchronously, and the mounting frame then drives the clamped welded parts to rotate to avoid the staff from changing the angle and reinstalling them after disassembly, thereby improving the work efficiency of the staff. The telescopic rod drives the mounting plate and the welding head at the bottom to rise and fall. When the mounting plate is raised or lowered, the convex plate moves along the guide rod inside the guide groove to guide and ensure that the welding head maintains a stable position and direction during operation, while avoiding deviation or jitter. The threaded rod is threadedly connected to the pressing plate to ensure that the pressing plate can be firmly fixed to the bottom of the threaded rod, which is also convenient for installation and disassembly, and is convenient for clamping welded parts of different sizes.
