Description

Technical Field

[0001] This utility model relates to the field of mechanical and electrical equipment manufacturing technology, and in particular to a portable welding device for manufacturing mechanical and electrical equipment. Background Technology

[0002] Portable welding equipment, as an indispensable tool in modern industrial manufacturing and maintenance, has been widely used in many fields due to its flexibility and efficiency. From automotive repair and construction to aerospace, portable welding equipment has significantly improved work efficiency and welding quality thanks to its compact size and powerful functions.

[0003] Portable welding devices have various welding methods, including electric welding, gas welding, and laser welding. Among them, electric welding can be further divided into several types. One common welding method is to use an electric heating wire or an alternating electric field to heat and weld pipes. This involves pre-burying a welding wire in the pipe section to be welded, then heating the welding wire. After the welding wire melts, it covers the weld seam, and after solidification, the two pipes are connected.

[0004] The existing electric heating head has a fixed shape. When heating the welding wire, the electric heating head is located on one or both sides of the welding wire. This causes the welding wire closer to the heating head to melt first, while the electric heating head further away from the welding wire melts later, resulting in uneven welds and affecting the welding strength.

[0005] Therefore, it is necessary to provide a portable welding device for manufacturing mechanical and electrical equipment to solve the above-mentioned technical problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the prior art, this utility model provides a portable welding device for mechanical and electrical equipment manufacturing that can uniformly heat the welding wire.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A portable welding device manufactured by mechanical and electrical equipment includes: a housing, a handle at one end of the housing, a clamping plate hinged to the other end of the housing, clamping plates on both the clamping plate and the housing, a metal tube that can be clamped between two clamping plates, a guide rail on the inner side of the housing, a geared disc slidably mounted on the guide rail, both the guide rail and the geared disc being C-shaped, a heating wire on the geared disc, and a motor on the inner side of the housing, the motor having a rotating shaft, a gear mounted at the distal end of the rotating shaft, the gear meshing with the geared disc.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) This utility model achieves the rotation effect of the gear plate by setting up motor and other related components. Compared with the existing fixed electric heating wire, the rotating electric heating wire can heat the welding wire to be heated evenly when working, so that the welding wire melts synchronously at the connection of the pipe, thereby making the weld more uniform and the welding strength higher.

[0016] (2) This utility model has a variety of clamps to adapt to pipes of different diameters. The clamps are easy to disassemble and replace, and the device has a wider range of applications.

[0017] (3) This utility model establishes a heat flow channel by setting up a cavity that runs through the top and bottom. After the heat is generated, it enters the outside air through the cavity, thereby improving the heat dissipation efficiency. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0025] First embodiment:

[0026] like Figure 1-5 As shown, the portable welding device for manufacturing mechanical and electrical equipment provided by this utility model includes: a shell 101, which has a hollow structure, with the welding component located inside the cavity of the shell 101; a handle 102 at one end of the shell 101, which is a handheld part; and a clamping plate 103 hinged to the other end of the shell 101. Both the clamping plate 103 and the shell 101 are provided with clamping pieces 104, the shapes of which are as follows: Figure 1 As shown, the clamping piece 104 has a semi-circular notch in the middle. The metal tube to be welded is clamped between the notches of the two clamping pieces 104. A guide rail 106 is fixedly installed on the inner side of the outer shell 101. A gear plate 107 is slidably mounted on the guide rail 106. Both the guide rail 106 and the gear plate 107 are C-shaped. An electric heating wire 105 is provided on the gear plate 107. The electric heating wire 105 can work by generating heat through resistance or by generating heat through an alternating electric field. A high-temperature resistant and heat-insulating ceramic ring is provided between the gear plate 107 and the electric heating wire 105. The electric heating wire 105 is fixed on the ceramic ring to prevent the heat generated by the electric heating wire 105 from damaging the gear plate. 107. Inside the outer casing 101, a motor 108 is also provided. The motor 108 has a rotating shaft, and a gear 109 is installed at the far end of the rotating shaft. The gear 109 meshes with the gear disc 107. In use, firstly, welding wire is embedded between the two pipes to be welded. Then, by holding the handle 102, the guide rail 106 of the device is passed through the pipe through its notch and placed on the notch of the clamp 104 on the outer casing 101. Finally, the two clamps 103 hinged to the outer casing 101 are closed, and the clamps 103 are fixed to the outer casing 101 using the latch 110. In this way, the device is fixed on the two pipes to be welded, and the position of the pipes is also fixed. Figure 4 As shown, when the motor 108 is started, the shaft of the motor 108 rotates, which drives the gear 109 to rotate. The gear 109 drives the gear disk 107 to rotate. At the same time, the heating wire 105 located on the gear disk 107 rotates synchronously with the gear disk 107. The motor 108 can work in a cyclic forward and reverse rotation manner, for example, driving the gear disk 107 to rotate forward half a turn and then reverse half a turn.

[0027] The rotation effect of the gear plate 107 is achieved by setting up a motor 108 and other related components. Compared with the existing fixed heating wire 105, the rotating heating wire 105 can heat the welding wire to be heated evenly when working, so that the welding wire melts synchronously at the connection of the pipe, resulting in a more uniform weld and higher welding strength.

[0028] Second embodiment:

[0029] like Figure 2 , Figure 5 As shown, the clamping plate 103 is provided with a slot 113, and the clamping piece 104 is provided with a protrusion that matches the slot 113. The clamping plate 103 and the clamping piece 104 are connected by a socket through the slot 113. The clamping piece 104 on the outer shell 101 is connected to the outer shell 101 in the same way. In order to improve the firmness of the connection, a magnetic piece is installed on the clamping piece 104. The magnetic attraction is used to improve the stability of the clamping piece 104 installation and facilitate disassembly and replacement. The clamping piece 104 has various specifications. They have the same outer diameter, but the diameter of the semi-circular notch of the clamping piece 104 is different for each specification.

[0030] By setting up clamps 104 of various specifications to adapt to pipes of different diameters, and by making the clamps 104 easy to disassemble and replace, the device has a wider range of applications.

[0031] Third embodiment:

[0032] like Figure 2 As shown, the interior of the outer casing 101 is a cavity, and the upper and lower ends of the outer casing 101 are connected. When the heating wire 105 is working, it will generate a lot of heat. There are also circuit boards and wires and other electronic components inside the outer casing 101 working together (electronic components are not shown in the figure). The heat will cause damage to the electronic components.

[0033] By creating a through-cavity, a channel for heat flow is established. After heat is generated, it enters the outside air through the through-cavity, thus improving heat dissipation efficiency.

[0034] Fourth embodiment:

[0035] like Figure 1 As shown, the handle 102 has an arc-shaped cross-section and a rubber layer on the outside of the handle 102. The arc-shaped handle 102 is more comfortable to hold, and the edges are chamfered. At the same time, the rubber layer attached to the surface of the handle 102 can increase the friction with the hand during use and prevent slipping.

[0036] Fifth embodiment:

[0037] like Figure 4 As shown, the shaft of the motor 108 has a certain length. The motor 108 is installed away from the heating wire 105. When the heating wire 105 is working, it will generate a lot of heat. Setting the shaft of the motor 108 to be long and installing the motor 108 at the end of the housing 101 away from the heating wire 105 can reduce the heat radiation from the heating wire 105 to the motor 108 and prevent the motor 108 from being damaged.

[0038] Sixth embodiment:

[0039] like Figure 2As shown, the outer casing 101 is provided with a connecting end 111, and a connecting rod 112 is threaded onto the connecting end 111. By setting the connecting rod 112, it is convenient to lift the device for high-altitude welding operations. In use, the worker on the ground holds the connecting rod 112 and lifts the device, while the worker at the height clamps the device onto the pipe to be welded according to the method in the first embodiment to perform the welding operation.

[0040] Working principle: First, welding wire is embedded between the two pipes to be welded. Then, by holding handle 102, the guide rail 106 of the device is passed through the pipe through its notch and placed on the notch of clamp 104 on the outer casing 101. Finally, the two clamps 103 hinged to the outer casing 101 are closed, and the clamps 103 are fixed to the outer casing 101 using the lock 110. In this way, the device is fixed to the two pipes to be welded, and the position of the pipes is also fixed. Figure 4 As shown, when the motor 108 is started, the rotation of the motor 108 shaft drives the gear 109 to rotate, and the gear 109 drives the gear disk 107 to rotate. Simultaneously, the heating wire 105 located on the gear disk 107 rotates synchronously with the gear disk 107. The above embodiment is only one preferred embodiment of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not substantial in nature, but which still solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
