Description

Technical Field

[0001] This utility model belongs to the field of welding equipment, specifically relating to an integrated cooling device for arc welding. Background Technology

[0002] Arc welding converts electrical energy into the heat and mechanical energy required for welding, achieving the goal of welding metals at high temperatures. It is widely used in various fields such as construction and building. Because the chaotic construction site often causes impact damage to the welding machine, effective safety protection is necessary. Protective enclosures are commonly used to protect the welding machine; however, existing protective enclosures have poor heat dissipation, affecting the welding machine's own cooling and often leading to problems such as high-temperature shutdowns. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model aims to provide an integrated cooling device for arc welding. This device can effectively protect the welding machine body, the welding machine body is easy to disassemble and assemble, and it can effectively cool and dissipate heat from the welding machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An integrated cooling device for arc welding includes a mobile cart, a housing, and a welding machine body. The housing is mounted on the mobile cart, and a cover plate is detachably installed at the opening on the top of the housing, abutting against the top of the welding machine body. A fixing assembly for clamping and fixing the welding machine body is installed inside the housing. The fixing assembly includes two parallel vertical plates and two clamping blocks. A horizontal plate is fixedly fixed at the bottom of the housing, and the two vertical plates are vertically and movably arranged on the left and right sides of the horizontal plate. Support blocks are fixedly installed on opposite sides of the two vertical plates, and the bottom sides of the welding machine body are supported on the support blocks. Eight-shaped guide grooves are symmetrically opened on the two vertical plates. The two clamping blocks are slidably mounted on the horizontal plate, abutting against the front and rear side walls of the welding machine body. Guide rods horizontally fixed on the left and right sides of the clamping blocks are slidably engaged in the corresponding guide grooves. Air inlets and outlets are symmetrically opened on the side walls of the housing. A cold water circulation mechanism is installed at the air inlet, and an exhaust fan is installed at the air outlet.

[0006] Preferably, the cold water circulation mechanism includes a heat exchange coil, a cold water tank, and a water pump. The cold water tank and the water pump are mounted on a mobile vehicle. The heat exchange coil is installed at the air inlet. The water inlet of the heat exchange coil is connected to the water outlet of the water pump. The water inlet of the water pump is connected to the bottom of the cold water tank through a suction pipe.

[0007] Preferably, a filter screen is also installed at the air inlet.

[0008] Preferably, the filter screen is installed on the outside of the heat exchange coil.

[0009] Preferably, the horizontal plate has two vertical holes that extend through it, and the vertical plate is vertically slidably installed in the corresponding vertical holes; the distance between the two vertical plates is adapted to the left and right length of the welding machine body.

[0010] Preferably, the guide rod moves horizontally through the corresponding guide groove and extends outward, and a limiting block is fixed at the end of the guide rod.

[0011] Preferably, a stabilizing plate is vertically fixed to the clamping block near the welding machine body.

[0012] Preferably, a base plate is horizontally fixed between the two vertical plates below the horizontal plate, and a first spring is vertically supported between the base plate and the inner bottom of the box.

[0013] Preferably, a second spring is vertically fixed to the bottom of the cover plate, and a pressure block is fixed to the lower end of the second spring, with the pressure block abutting against the top of the welding machine body.

[0014] Preferably, the cover plate is installed at the opening of the box via a snap-fit ​​structure.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. When the welding machine body of this application is installed, its left and right sides are clamped downward between the two vertical plates and supported on the two support blocks. Under the weight of the welding machine body, the two vertical plates will be pressed down and the first spring will be squeezed. With the cooperation of the eight-shaped guide groove and the guide rod, the front and rear clamping blocks will approach each other and clamp and fix the front and rear side walls of the welding machine body through the stabilizing plate, thereby providing stable support and clamping fixation for the welding machine body.

[0017] 2. After the cover plate of this application is fastened to the opening of the box, under the action of the second spring, it will press down on the top of the welding machine body through the pressure block. This not only effectively fixes the welding machine body, but also provides an additional downward pressure. Thus, with the cooperation of the vertical plate, guide rod and clamping block and other structures, the clamping and fixing of the welding machine body is more secure.

[0018] 3. In this application, under the action of the exhaust fan, external air enters the chamber through the filter and heat exchange coil. The heat exchange coil, under the suction action of the water pump, can cool the air entering the chamber. After the cold air enters the chamber, it can effectively cool the welding machine body. The exhaust fan can draw the hot air out of the chamber, accelerate the air flow inside the chamber, and improve the heat dissipation efficiency. Attached Figure Description

[0020] Figure 2This is a schematic diagram of the structure of the fixing component of this utility model. Detailed Implementation

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0022] like Figure 1-2 As shown, this utility model proposes an integrated cooling device for arc welding, including a mobile cart 1, a housing 4, and a welding machine body 5. The housing 4 is mounted on the mobile cart 1, facilitating the transport and movement of the arc welding machine. A cover plate 41 is detachably installed at the opening on the top of the housing 4. In specific implementation, the cover plate 41 can be installed at the opening of the housing 4 through a snap-fit ​​structure 42, which facilitates the opening and fixing of the cover plate 41 and makes it convenient to put the welding machine body 5 into and out of the housing 4.

[0023] The housing 4 contains a fixing assembly for clamping and securing the welding machine body 5. The fixing assembly includes two parallel vertical plates 61 and two clamping blocks 62. A horizontal plate 45 is fixedly mounted at a certain height below the interior of the housing 4. Two vertical holes 451 are vertically drilled through the left and right sides of the horizontal plate 45. The two vertical plates 61 are vertically slidably installed in the corresponding holes 451. The distance between the two vertical plates 61 is adapted to the left and right length of the welding machine body 5, allowing the welding machine body 5 to be precisely clamped between the two vertical plates 61, effectively limiting the left and right sides of the welding machine body 5 and preventing it from shaking when moving.

[0024] Support blocks 611 are fixedly installed on the inner sides of the two opposing vertical plates 61. The bottom sides of the welding machine body 5 are supported on the support blocks 611, which can effectively support the welding machine body 5. The two vertical plates 61 are symmetrically provided with "eight"-shaped guide grooves 610. The horizontal plate 45 is provided with a sliding groove 452 in the front-back direction. The bottoms of the two clamping blocks 62 are slidably installed in the sliding groove 452, which can effectively limit the sliding of the clamping blocks 62. Guide rods 622 are horizontally fixed on the left and right sides of the clamping blocks 62. The guide rods 622 move horizontally through the corresponding guide grooves 610 and extend outward. The ends of the guide rods 622 are fixed with limiting blocks 623, which can effectively limit the movement of the guide rods 622 and prevent the guide rods 622 from disengaging from the guide grooves 610. In this embodiment, a stabilizing plate 621 is also vertically fixed upward on the side of the clamping block 62 near the welding machine body 5. The clamping block 62 is clamped on the front and rear sides of the welding machine body 5 by the stabilizing plate 621, which can effectively clamp and fix the welding machine body 5 from the front and rear direction, improving the stability of the welding machine body 5 installation. In specific implementation, the stabilizing plate 621 is fixed on both sides near the clamping block 62, exposing the heat dissipation holes in the middle of the welding machine body 5. While achieving effective clamping and fixing, it does not affect the heat dissipation of the welding machine body 5 itself.

[0025] In addition, a base plate 63 is horizontally fixed between the two vertical plates 61 below the horizontal plate 45, and a first spring 64 is vertically supported between the base plate 63 and the inner bottom of the housing 4. The first spring 64 can effectively support the two vertical plates 61 through the base plate 63, and provide restoring force for the vertical plates 61 to return to their upward position.

[0026] When the welding machine body 5 of this application is installed, its left and right sides are clamped downward between the two vertical plates 61 and supported on the two support blocks 611. Under the action of the gravity of the welding machine body 5, the two vertical plates 61 will be pressed downward and the first spring 64 will be squeezed. With the cooperation of the octagonal guide groove 610 and the guide rod 622, the front and rear clamping blocks 62 will approach each other and clamp and fix the front and rear side walls of the welding machine body 5 through the stabilizing plate 621, thereby providing stable support and clamping fixation for the welding machine body 5.

[0027] A second spring 43 is vertically fixed to the bottom of the cover plate 41, and a pressure block 44 is fixed to the lower end of the second spring 43. The pressure block 44 abuts against the top of the welding machine body 5. After the cover plate 41 is fastened to the opening of the housing 4, under the elastic force of the second spring 43, the pressure block 44 will press down on the top of the welding machine body 5. This not only effectively fixes the welding machine body 5, but also provides an additional downward pressure. Thus, with the cooperation of the vertical plate 61, the guide rod 622, and the clamping block 62, the clamping and fixing of the welding machine body 5 is more secure.

[0028] The side walls of the housing 4 are symmetrically equipped with air inlets 401 and air outlets 402. A cold water circulation mechanism and a filter screen 3 are installed at the air inlet 401 on the left side, and an exhaust fan 46 is installed at the air outlet 402. The filter screen 3 is installed on the outside of the heat exchange coil 23 and can effectively filter the air entering the housing 4 to prevent foreign objects from entering the housing 4. The cold water circulation mechanism includes a heat exchange coil 23, a cold water tank 21, and a water pump 22. The cold water tank 21 and the water pump 22 are installed on the mobile vehicle 1. The heat exchange coil 23 is installed at the air inlet 401. The water inlet of the heat exchange coil 23 is connected to the water outlet of the water pump 22. The water inlet of the water pump 22 is connected to the bottom of the cold water tank 21 through a suction pipe 221.

[0029] Under the action of the exhaust fan 46, external air enters the housing 4 through the filter screen 3 and heat exchange coil 23. The heat exchange coil 23, under the suction action of the water pump 22, can cool the air entering the housing 4. After the cold air enters the housing 4, it can effectively cool the welding machine body 5. The exhaust fan 46 can draw the hot air out of the housing 4, accelerate the air flow inside the housing 4, and improve the heat dissipation efficiency.

[0030] When using this utility model, the welding machine body 5 is placed downwards between the support block 611 and the two vertical plates 61. The front and rear clamping blocks 62 effectively clamp and fix the welding machine body 5 through the stabilizing plate 621. After the upper cover plate 41 is fixed by the buckle structure 42, it will effectively clamp the top of the welding machine body 5 through the second spring 43 and the pressure block 44. During the arc welding operation, with the cooperation of the exhaust fan 46 and the cold water circulation mechanism, the air entering the box 4 can be cooled and the hot air inside the box 4 can be sucked out, accelerating the air flow inside the box 4 and improving the heat dissipation efficiency.

The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
