Description

Technical Field

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

[0002] Electric welding machines utilize the high-temperature electric arc generated when the positive and negative electrodes are momentarily short-circuited to melt the welding rod and the material being welded, achieving atomic bonding. Their structure is relatively simple, primarily consisting of a high-power transformer that, through the principle of inductance, generates a significant voltage change when the circuit is switched on and off, thereby initiating the electric arc.

[0003] Traditional welding machines typically have a panel for connecting welding guns located on the front of the machine housing. This panel usually includes three-phase or single-phase power outlets as well as outlets for different types of welding guns or clamps. In other words, the panel usually has multiple outlets with the same function but different types. This can easily lead to incorrect connections by operators who are not familiar with the welding machine, which can easily damage the welding machine and pose a significant safety hazard. This issue needs to be addressed. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a welding machine that separates different types of connectors on the machine casing, thereby preventing accidental insertion that could damage the welding machine and eliminating safety hazards.

[0005] In view of the above, this utility model provides an electric welding machine, comprising:

[0006] The casing contains an energy conversion and supply mechanism, a control mechanism, a power output and regulation mechanism, a protection mechanism, and a power supply mechanism.

[0007] The first functional area is located on the front of the casing;

[0008] The second functional block is located on the side of the casing;

[0009] The display area is located on the front of the casing and above the first functional area.

[0010] In the above technical solution, further:

[0011] Both the first and second functional blocks include a power socket, a welding gun socket, and a grounding socket.

[0012] In the above technical solution, further:

[0013] The display area includes a display screen, a current adjustment knob, and a voltage adjustment knob.

[0014] Furthermore, the above technical solution also includes:

[0015] A protective cover is installed on the side of the housing and is used to cover the second functional area.

[0016] The side of the casing has an opening in the second functional area that is compatible with the protective cover.

[0017] Furthermore, the above technical solution also includes:

[0018] A connector is installed at one end of the protective cover and is used for the hinged connection between the protective cover and the housing;

[0019] The latch is installed on the protective cover;

[0020] A stop block is set on the inner wall of the opening and connected to the housing, and is used to lock the protective cover in conjunction with the latch.

[0021] In the above technical solution, the connector further includes:

[0022] The first U-shaped block is clamped and set on the housing and located on the bottom wall of the opening;

[0023] The second U-shaped block is clamped on the side of the protective cover and hinged to the first U-shaped block.

[0024] In the above technical solution, further:

[0025] Both the first U-shaped block and the second U-shaped block have threaded holes at one end inside the casing;

[0026] Among them, the first U-shaped block and the second U-shaped block are located at one end outside the housing, and the housing and the protective cover are all provided with round holes coaxial with the threaded holes, and bolts are installed thereon.

[0027] In the above technical solution, further:

[0028] The casing has ventilation holes in both the first and second functional blocks.

[0029] The beneficial effects of this utility model are as follows:

[0030] 1. By adding a functional block on the side of the machine housing, the frequently used and easily mis-inserted sockets are placed in the first functional block on the front of the machine housing, while the less frequently used and easily mis-inserted sockets are placed in the second functional block on the side of the machine housing. This avoids mis-insertion by operators unfamiliar with the welding machine, prevents damage to the welding machine, and eliminates safety hazards.

[0031] 2. By setting a protective cover to shield the second functional block, the protection and dust prevention of the second functional block's sockets are improved, avoiding damage to the sockets due to infrequent use.

[0032] 3. By using the first U-shaped block to connect the housing and the second U-shaped block to connect the protective cover, the convenience of connection is improved. There is no need to use nuts for tightening; only bolts are needed. At the same time, it avoids the need for disassembly when using nuts for tightening, which could cause the nuts to fall into the housing. Attached Figure Description

[0036] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0037] Example 1:

[0038] This embodiment provides an electric welding machine, including:

[0039] The casing 1 contains an energy conversion and supply mechanism, a control mechanism, a power output and regulation mechanism, a protection mechanism, and a power supply mechanism.

[0041] The second functional block 3 is located on the side of the casing 1;

[0042] Display block 4 is located on the front of the casing 1 and above the first functional block 2;

[0043] The specific structures of the energy conversion and supply mechanism, control mechanism, power output and regulation mechanism, protection mechanism, and power supply mechanism are all existing technologies, which can be learned by those skilled in the art from traditional electric welding machines, and will not be described in detail here.

[0044] As can be seen from this embodiment, by adding a functional block on the side of the housing 1, the commonly used and easily mis-inserted sockets are placed in the first functional block 2 on the front of the housing 1, and the less commonly used and easily mis-inserted sockets are placed in the second functional block 3 on the side of the housing 1. This avoids mis-insertion by operators unfamiliar with the welding machine, prevents damage to the welding machine, and eliminates safety hazards.

[0045] Example 2:

[0046] This embodiment provides an electric welding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0047] Both the first functional block 2 and the second functional block 3 include a power socket, a welding gun socket, and a grounding socket.

[0048] The power socket and welding gun socket are connected to the power output and adjustment mechanism, while the grounding socket is connected to the housing 1. The first functional block 2 and the second functional block 3 may also include control sockets and other auxiliary sockets, such as gas protection sockets and cooling water sockets. These are existing technologies and can be understood by those skilled in the art from existing welding machines, so they will not be described in detail here.

[0049] As can be seen from this embodiment, by providing power sockets, welding gun sockets and grounding sockets in both the first functional block 2 and the second functional block 3, it is convenient to connect the required connectors to the first functional block 2 and the second functional block 3 respectively when using different functional blocks, avoiding the need to connect connectors on the two functional blocks and avoiding confusion.

[0050] Example 3:

[0051] This embodiment provides an electric welding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0052] Display block 4 includes a display screen, a current adjustment knob, and a voltage adjustment knob;

[0053] The specific structure of the display screen and the working principles of the current adjustment knob and voltage adjustment knob are existing technologies, which can be understood by those skilled in the art from existing welding machines, and will not be elaborated here.

[0054] As can be seen from this embodiment, the display block 4 makes it easy to understand the output status, while the current adjustment knob and voltage adjustment knob facilitate the adjustment of the output, improving ease of use.

[0055] Example 4:

[0056] This embodiment provides an electric welding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes:

[0057] The protective cover 5 is installed on the side of the housing 1 and is used to cover the second functional block 3;

[0058] The side of the casing 1 has an opening 6 that is adapted to the protective cover 5 at the second functional block 3.

[0059] As can be seen from this embodiment, by setting a protective cover 5 to shield the second functional block 3, the protection and dust prevention of the socket of the second functional block 3 are improved, and the socket is prevented from being damaged due to infrequent use.

[0060] The opening 6 on the side of the casing 1, which is adapted to the protective cover 5, helps to ensure the flatness of the side of the casing 1 and ensures its aesthetics.

[0061] Example 5:

[0062] This embodiment provides an electric welding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes:

[0063] Connector 7 is installed at one end of the protective cover 5 and is used for the hinge connection between the protective cover 5 and the housing 1;

[0064] Lock 8 is installed on protective cover 5;

[0065] The stop block 9 is set on the inner wall of the opening 6 and connected to the housing 1, and is used to lock the protective cover 5 in conjunction with the latch 8;

[0066] Among them, the stop block 9 and the housing 1 adopt an integrated structure;

[0067] Meanwhile, the specific structure of the latch 8 is existing technology, and those skilled in the art can obtain the specific structure of the conventional latch 8 from the public knowledge, so it will not be described in detail here.

[0068] As can be seen from this embodiment, the cooperation of the stop block 9 and the latch 8 facilitates the locking of the protective cover 5, improves the stability of the protective cover 5, prevents the protective cover 5 from being embedded in the housing 1 or flipped outward, and ensures the protective effect on the second functional block 3.

[0069] Example 6:

[0070] This embodiment provides a welding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features, wherein the connecting member 7 includes:

[0071] The first U-shaped block 70 is clamped and set on the housing 1 and located on the bottom wall of the opening 6;

[0072] The second U-shaped block 71 is clamped and disposed on the side of the protective cover 5 and is hinged to the first U-shaped block 70.

[0073] As can be seen from this embodiment, by using the first U-shaped block 70 and the second U-shaped block 71, that is, by using a clamping method to connect them to the housing 1 and the protective cover 5, the connection strength and stability are improved. At the same time, the installation connection is not impossible due to the thinness of the housing 1 and the protective cover 5, thus improving the adaptability.

[0074] Furthermore, the rotation angle between the first U-shaped block 70 and the second U-shaped block 71 is 0-180°, while due to the setting of the stop block 9, the rotation angle between the first U-shaped block 70 and the second U-shaped block 71 is 0-90°. That is to say, when the protective cover 5 is opened, it is in a horizontal state, which avoids the protective cover 5 from sticking to the surface of the casing 1 after it is opened, and improves the convenience of closing the protective cover 5. In order to make the protective cover 5 obliquely downward after it is opened, reduce the possibility of bumping, and also prevent the protective cover 5 from sticking to the casing 1, the connection between the first U-shaped block 70 and the second U-shaped block 71 can be chamfered.

[0075] Example 7:

[0076] This embodiment provides an electric welding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0077] The first U-shaped block 70 and the second U-shaped block 71 both have threaded holes 72 at one end inside the housing 1;

[0078] Among them, the first U-shaped block 70 and the second U-shaped block 71 are located at one end outside the housing 1, and the housing 1 and the protective cover 5 are both provided with round holes coaxial with the threaded hole 72, and bolts 73 are installed thereon.

[0079] As can be seen from this embodiment, by using the first U-shaped block 70 to connect the housing 1 and the second U-shaped block 71 to connect the protective cover 5, the convenience of connection is improved. There is no need to use nuts for tightening; only bolts 73 are needed. At the same time, it avoids disassembly when using nuts for tightening, as the nuts may fall into the housing 1. In addition, the connection strength is high, avoiding the stripping of bolts 73, ensuring stable installation, and extending service life.

[0080] Example 8:

[0081] This embodiment provides an electric welding machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0082] The casing 1 has heat dissipation holes 10 at both the first functional block 2 and the second functional block 3.

[0083] As can be seen from this embodiment, the opening of the heat dissipation hole 10 facilitates targeted heat dissipation of the first functional block 2 and the second functional block 3, ensuring the safety of the welding machine and extending its service life.
