Description

Technical Field

[0001] This utility model relates to the field of electric welding machine technology, and in particular to an electric welding machine that prevents overheating. Background Technology

[0002] Electric welding machines are common welding equipment, mainly used for welding metal materials. They fuse two metal workpieces together using an electric arc or resistance, and are widely used in various fields such as machinery manufacturing, construction engineering, and automobile manufacturing. When using an electric welding machine, a certain length of wire is connected to it. Generally, welding machines are conveniently placed on the ground, which makes the working environment cluttered. If the welding machine or its connected wire is accidentally tripped over, it can cause the welding machine and wire to loosen or detach, leading to power outages and unstable arcs during welding. This not only affects the progress of the welding work but also easily damages the connection between the wire and the welding machine. Therefore, to further improve the practicality of welding machines, we propose an overheat-prevention welding machine to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a welding machine that prevents overheating. By setting a clamping component on the front surface of the welding machine body and located on both sides of the welding machine socket, the wire plug is clamped and fixed, which is used to prevent the wire connected to the welding machine body from being pulled excessively during use, causing the wire to loosen or fall off. This avoids situations such as power outages or unstable arcs during welding due to unreliable or loose wire connections. As a result, wear between the connection socket and the wire plug can be reduced, and the service life of the welding machine can be extended.

[0004] This utility model also provides a welding machine with the above-mentioned anti-overheating function, comprising: a welding machine body, a heat dissipation vent on the rear surface of the welding machine body, a cooling fan fixedly connected to the inner side of the heat dissipation vent, a heat sink fixedly connected to the inner side of the welding machine body, a heat dissipation window one and a heat dissipation window two fixedly connected to the two sides of the welding machine body respectively, a heat dissipation window three fixedly connected to the front surface of the welding machine body, an insertion port provided on the front surface of the welding machine body, and a clamping assembly fixedly connected to the front surface of the welding machine body. The clamping assembly consists of a movable connecting plate, a slide rail, a clamping plate one, a connecting hole, a clamping plate two, and a connecting plug. Two slide rails are symmetrically arranged, and the two slide rails are located on both sides of the insertion port respectively.

[0005] According to the present invention, an overheat-preventing welding machine includes a movable connecting plate slidably connected to a slide rail. The movable connecting plate is L-shaped, and two movable connecting plates are symmetrically arranged. This allows the two movable connecting plates to move simultaneously via the slide rail.

[0006] According to the present invention, in a welding machine designed to prevent overheating, the sides of the two movable connecting plates are respectively rotatably connected to clamping plate one and clamping plate two via hinges. This facilitates connection with the movable connecting plates.

[0007] According to the present invention, a welding machine for preventing overheating includes a clamping plate one and a clamping plate two having the same shape. The connecting hole is located on the side of the clamping plate one, and the connecting plug is located on the side of the clamping plate two. This design ensures consistency and firmness between the two clamping plates when clamping objects.

[0008] According to the present invention, an electric welding machine for preventing overheating has a connecting hole and a connecting plug with the same shape and length, and the inner wall surface of the connecting hole is threaded. This provides a certain amount of friction when the connecting plug is connected to the connecting hole.

[0009] According to the present invention, an electric welding machine for preventing overheating has an arc-shaped clamping surface on both clamping plate one and clamping plate two, and grooves are provided on the clamping surfaces of both clamping plate one and clamping plate two. This enhances the clamping firmness and facilitates contact with the surface of the object being clamped.

[0010] According to the present invention, a welding machine for preventing overheating is provided, wherein a sealing door is rotatably connected to the side of the welding machine body, and a filter screen is fixedly connected to the inner surface of the sealing door, the filter screen being located on the inner surface of a heat dissipation window. This facilitates internal maintenance of the welding machine body and prevents impurities and dust from entering the interior of the welding machine body.

[0011] According to the present invention, in a welding machine designed to prevent overheating, the first and second heat dissipation windows are positioned opposite each other, and the third heat dissipation vent is positioned opposite each other. This increases the heat dissipation area inside the welding machine body.

[0012] Beneficial effects: By setting clamping components on the front surface of the welding machine body and placing them on both sides of the welding machine socket, the wires are clamped and fixed in place. This prevents the wires connected to the welding machine body from being pulled excessively during use, causing them to loosen or fall off. This avoids situations such as power outages or unstable arcs during welding due to unreliable or loose wire connections. As a result, wear between the connection socket and the wire plug can be reduced, extending the service life of the welding machine. Attached Figure Description

Detailed Implementation

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-5This utility model discloses a welding machine for preventing overheating, comprising: a welding machine body 1, an overall structure of the welding equipment, a heat dissipation vent 7 on the rear surface of the welding machine body 1 for connecting a cooling fan 8, which, combined with a heat dissipation window 31, forms an air convection channel and inlet / outlet. The cooling fan 8 is fixedly connected to the inner side of the heat dissipation vent 7, and heat sinks 10 are fixedly connected to the inner side of the welding machine body 1 to accelerate and increase the speed and area of ​​heat dissipation inside the welding machine body 1. Heat dissipation windows 31 and 321 are fixedly connected to two sides of the welding machine body 1 respectively, forming a transverse channel for heat dissipation inside the welding machine body 1. The front surface of the welding machine body 1 is fixedly connected to a heat dissipation window 3 4. The front surface of the welding machine body 1 is provided with a socket 5, which is the main power input port of the welding machine. The front surface of the welding machine body 1 is fixedly connected to a clamping assembly, which consists of a movable connecting plate 6, a slide rail 61, a clamping plate 1 62, a connecting hole 602, a clamping plate 2 63, and a connecting plug 603. It is used to clamp the wires connected to the welding machine body 1, enhance the firmness between the wires and the socket 5, and avoid excessive pulling on the wires, which would cause the wires to loosen or fall off. There are two slide rails 61 symmetrically arranged, and the two slide rails 61 are located on both sides of the socket 5 to ensure the synchronization of the movable connecting plate 6.

[0023] The movable connecting plate 6 is slidably connected to the slide rail 61. The movable connecting plate 6 is L-shaped, and two movable connecting plates 6 are symmetrically arranged to allow simultaneous movement of both plates via the slide rail 61, fixing the cable connection end to be clamped. The sides of the two movable connecting plates 6 are rotatably connected to clamping plate one 62 and clamping plate two 63 respectively via hinges, facilitating connection with the movable connecting plate 6. Clamping plate one 62 and clamping plate two 63 have the same shape. The connecting hole 602 is located on the side of clamping plate one 62, and the connecting plug 603 is located on the side of clamping plate two 63, ensuring consistency and firmness when clamping objects. The connecting hole 602 and the connecting plug 603 have the same shape and length. The inner wall of the connecting hole 602 is threaded, allowing for connection when the connecting plug 603 is connected to the connecting hole 602. There is a certain amount of friction, making it difficult for the two to be pulled apart when connected. The clamping surfaces of clamping plate 1 62 and clamping plate 2 63 are designed as arc surfaces to facilitate contact with the surface of the object being clamped. The clamping surfaces of clamping plate 1 62 and clamping plate 2 63 are provided with grooves to enhance the clamping firmness. A sealing door 2 is rotatably connected to the side of the welding machine body 1 to facilitate internal maintenance of the welding machine body 1. A filter screen 9 is fixedly connected to the inner surface of the sealing door 2. The filter screen 9 is located on the inner surface of heat dissipation window 1 3 to prevent impurities and dust from entering the interior of the welding machine body 1 and to ensure the cleanliness of the internal environment of the welding machine body 1. The positions of heat dissipation window 1 3 and heat dissipation window 2 31 are corresponding, and the positions of heat dissipation vent 7 and heat dissipation window 3 4 are corresponding to increase the heat dissipation area inside the welding machine body 1 and optimize the internal air circulation.

[0024] Working principle: When using this overheat-preventing welding machine, after the wire is connected to the socket 5 of the welding machine body 1, the user moves the two movable connecting plates 6 to the socket position at the same time. When the clamping surfaces of clamping plate 1 62 and clamping plate 2 63 are in contact with the outer surface of the wire, at the same time, the connecting plug 603 is squeezed into the interior of the connecting hole 602. The thread inside the connecting hole 602 increases the friction of the connecting plug 603, preventing the connecting plug 603 from being easily pulled out of the connecting hole 602, thus ensuring the firmness of the connection between clamping plate 1 62 and clamping plate 2 63. The cooling fan 8 delivers cold air from outside to the interior of the welding machine body 1, while the hot air inside the welding machine body 2 is dissipated from the heat dissipation window 3 4. The heat sink 10 quickly dissipates heat through the heat dissipation window 2 31, and the filter screen 9 connected to the heat dissipation window 1 3 filters out external impurities and dust.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
