[0034] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0035] like Figure 1-Figure 5 As shown, this embodiment discloses a welding machine. The welding machine includes a shell 1, a first partition 15, a second partition 16, a control component 2, a power supply component 3 and an air supply component 4. The shell 1 includes a bottom plate 11, two side plates 12, a front plate 13 and a rear plate 14. The front plate 13, the rear plate 14 and the two side plates 12 are relatively arranged on the bottom plate 11. The two side plates 12, the front plate 13 and the rear plate 14 are connected and are surrounded together with the bottom plate 11 to form the shell 1. The first partition 15 and the second partition 16 are arranged in the shell 1 at intervals, and the shell 1 is divided into a first accommodating chamber, a second accommodating chamber and a third accommodating chamber which are arranged adjacent to each other from top to bottom in the vertical direction. The first accommodating chamber is installed with the control component 2, the second accommodating chamber is installed with the power supply component 3, and the third accommodating chamber is installed with the air supply component 4.

[0036] like Figure 1 and Figure 2As shown, the welding machine of this embodiment divides the shell 1 of the welding machine into a first accommodating chamber, a second accommodating chamber and a third accommodating chamber by a first partition 15 and a second partition 16, thereby realizing the layered installation of the components of the welding machine. The control component 2 is installed in the first accommodating chamber located at the top, which is convenient for operation and maintenance of the control component 2. The power supply component 3 is installed in the second accommodating chamber, which is conducive to connecting the power supply component 3 with the control component 2 and the gas supply component 4 respectively, and optimizing the wiring layout. The gas supply component 4 is installed in the third accommodating chamber located at the bottom, which reduces the vibration of the welding machine and is conducive to improving the stability of the welding machine. At the same time, the welding machine is integrated with the gas supply component 4, which improves the integration of the welding machine, makes the overall structure of the welding machine compact, reduces the floor space, and is convenient for centralized control.

[0037] It should be noted that the welding machine of this embodiment also includes a cover plate (not shown in the figure). The top of the shell 1 has an opening, and the cover plate is detachably covered on the opening, so that the first accommodating chamber of the shell 1 forms a closed space, improving the waterproof and dustproof performance of the control component 2. The control component 2 is installed in the first accommodating chamber, which is convenient for the operator to open the cover plate at any time for maintenance or repair. The control component 2 is mainly used for the operation control of the welding machine. The control component 2 is a mature technical means in the technical field of welding machines. The composition, wiring and working principle of the control component 2 will not be repeated here.

[0038] like Figure 1 As shown, the portion of the front plate 13 surrounding the first accommodating cavity is inclined toward the first accommodating cavity to form an inclined section 131, and the inclined section 131 is installed with a control panel 132. The control panel 132 is installed on the inclined section 131 of the front plate 13 for easy operation and observation by operators.

[0039] Preferably, the welding machine further comprises a baffle 18, which is sandwiched between the first baffle 15 and the second baffle 16 and encloses a closed space in the second accommodating cavity. The power supply assembly 3 comprises an electronic component 31, which is installed in the closed space to prevent the electronic component 31 from being subjected to electronic interference, improve the stability of the power supply assembly 3, and make the electronic component 31 have good waterproof and dustproof effects.

[0040] like Figure 3 and Figure 4 As shown, the baffle 18 includes a first vertical plate 181 and a second vertical plate 182 connected to each other. The first vertical plate 181 is connected to the rear plate 14, and the second vertical plate 182 is connected to one of the side plates 12. The baffle 18, the first partition plate 15, the second partition plate 16, and the rear plate 14 are connected to one of the side plates 12 and are together enclosed to form a closed space. The electronic component 31 is installed on the first vertical plate 181.

[0041] The two side panels 12 of this embodiment are respectively vertically arranged on both sides of the bottom plate 11 in the width direction thereof. For the convenience of description, the two side panels 12 are referred to as the left side panel and the right side panel. The first vertical panel 181 is perpendicular to the second vertical panel 182, so that the baffle 18 is an "L"-shaped panel, the upper end of the baffle 18 is connected to the first partition 15, and the lower end of the single panel is connected to the second partition 16. The enclosed space is formed by the baffle 18, the first partition 15, the second partition 16, and the left side panel or the right side panel, and the electronic component 31 is installed on the side wall of the first vertical panel 181 in the enclosed space. The first vertical panel 181 of this embodiment is parallel to the side panel 12, and the second vertical panel 182 is parallel to the rear panel 14, so that the enclosed space is a regular rectangular cavity, which optimizes the layout of the power supply component 3 in the second accommodating cavity and improves the space utilization rate of the second accommodating cavity.

[0042] Preferably, the number of baffles 18 is two, and the two first vertical plates 181 are arranged opposite to each other, and are enclosed together with the first partition plate 15 and the second partition plate 16 to form a heat dissipation channel, and a fan 19 is installed at the position of the rear plate 14 facing the heat dissipation channel. The two baffles 18 are arranged opposite to each other. In the second accommodating cavity, one baffle 18, the first partition plate 15, the second partition plate 16 and the left side plate are enclosed to form a closed space, and the other baffle 18, the first partition plate 15, the second partition plate 16 and the right side plate are enclosed to form another closed space. The electronic components 31 can be installed on the side walls of the first vertical plates 181 in the two closed spaces according to the design requirements, which increases the installation area of ​​the electronic components 31, is conducive to optimizing the layout of the electronic components 31 and improving the rapid heat dissipation of the electronic components 31. The heat generated by the electronic components 31 in the closed space can be quickly dissipated to the heat dissipation channel through the first vertical plates 181, and the fan 19 can quickly take away the heat in the heat dissipation channel, thereby improving the heat dissipation efficiency and facilitating the stable operation of the electronic components 31.

[0043] Further preferably, a heat dissipation hole 133 is provided at a position of the front plate 13 directly opposite to the heat dissipation channel. The heat in the heat dissipation channel can be quickly discharged from the shell 1 through the heat dissipation hole 133 under the action of the fan 19. The heat dissipation hole 133 of this embodiment is a strip hole, and the upper edge of the strip hole is connected to an arc plate, which extends from top to bottom in the vertical direction to prevent rainwater outside the shell 1 from entering the second accommodating cavity, thereby preventing the power supply component 3 from short-circuiting and keeping the power supply component 3 in the second accommodating cavity in a dry working environment. Of course, the heat dissipation hole 133 can also be a circular hole or other polygonal hole. Here, the size and number of the heat dissipation holes 133 are not specifically limited.

[0044] Further preferably, a heat sink 183 is disposed on the side of the first vertical plate 181 located in the heat dissipation channel. A plurality of heat sinks 183 are evenly disposed on the side of the first vertical plate 181 located in the heat dissipation channel, further improving the heat dissipation efficiency of the electronic component 31 .

[0045] like Figure 2 and Figure 4 As shown, the power supply component 3 also includes a transformer 32 and an impedance 33, and the transformer 32 and the impedance 33 are both installed on the second partition 16 at a position directly opposite to the heat dissipation channel. In this embodiment, the transformer 32 and the impedance 33 are spaced apart on the second partition 16, and the airflow of the heat dissipation channel can quickly bring the heat generated by the transformer 32 and the impedance 33 out of the housing 1, thereby improving the heat dissipation efficiency of the transformer 32 and the impedance 33. Moreover, a plurality of ventilation holes are provided on the two side panels 12 at positions directly opposite to the transformer 32 and the impedance 33, further increasing the heat dissipation effect of the transformer 32 and the impedance 33. The ventilation holes of this embodiment have the same structure as the above-mentioned heat dissipation holes 133.

[0046] The power supply component 3 of this embodiment can be connected to an external power supply, and convert the voltage and current of the external power supply into the working voltage and current of the welding machine, and has a power conversion function. The power supply component 3 may also include other components required for power conversion. Since the power supply component 3 with power conversion function is a conventional technical means in the field of welding machine technology, the composition and working principle of the power supply component 3 will not be described in detail.

[0047] It should be noted that a plurality of wiring holes (not shown in the figure) are provided on the first partition plate 15 and the second partition plate 16 to interconnect the first accommodating chamber, the second accommodating chamber and the third accommodating chamber. The power supply component 3 is connected to the control component 2 in the first accommodating chamber and the air supply component 4 in the third accommodating chamber through the wiring holes to provide power to the control component 2 and the air supply component 4. Installing the power supply component 3 between the control component 2 and the air supply component 4 is conducive to reducing the wiring length and optimizing the wiring layout.

[0048] Preferably, the air supply assembly 4 includes an air tank 41 and an air compressor 42, and the air tank 41 and the air compressor 42 are installed side by side on the bottom plate 11. Integrating the air tank 41 and the air compressor 42 into the welding machine improves the integration of the welding machine, reduces the floor space of the welding machine, facilitates the centralized control of the welding machine, and improves the convenience of operation of the welding machine. Since the air compressor 42 vibrates when compressing air, installing the air tank 41 and the air compressor 42 in the third accommodating chamber at the bottom can effectively reduce the impact of vibration on the welding machine and improve the stability of the welding machine.

[0049] like Figure 3 and Figure 5 As shown, the gas tank 41 is installed at the end of the bottom plate 11 close to the front plate 13, and the air compressor 42 is installed at the end of the bottom plate 11 close to the rear plate 14. The gas tank 41 is connected to a pressure regulating valve 411, which is used to adjust the gas pressure output by the gas tank 41.

[0050] like Figure 3 and Figure 6 As shown, the rear plate 14 is provided with a first through hole 141, and the filter port 421 of the air compressor 42 is penetrated in the first through hole 141. The front plate 13 is provided with a second through hole 134, and the external cutting torch can pass through the second through hole 134 to communicate with the gas tank 41. The second through hole 134 of this embodiment is a rectangular hole, and the pressure regulating valve 411 is arranged opposite to the second through hole 134, and the external cutting torch can communicate with the gas tank 41 through the pressure regulating valve 411. The opening size of the rectangular hole is larger than the size of the pressure regulating valve 411, so that the rectangular hole has a heat dissipation function. In order to achieve good ventilation and heat dissipation of the third accommodating chamber, a plurality of ventilation holes are provided at the position opposite to the side plate 12 and the air compressor 42 and at the position opposite to the rear plate 14 and the air compressor 42. The external air is filtered through the filter port 421 of the air compressor 42, compressed, and transported to the gas tank 41. The air compressor 42 has two filter ports 421 , and the rear plate 14 has two first through holes 141 correspondingly adapted to the filter ports 421 .

[0051] like Figure 1-Figure 3 As shown, the welding machine also includes a handle 5 and a roller 6. The handle 5 is mounted on the inclined section 131 of the front plate 13 for easy push and pull operation. Four rollers 6 are mounted at the lower end of the bottom plate 11 of the welding machine, which is conducive to the rapid movement of the welding machine so that the welding machine can be quickly moved to a designated work station.

[0052] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
