Description

Technical Field

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

[0002] Electric welding machines utilize the high-temperature electric arc generated when the positive and negative poles are momentarily short-circuited to melt the solder on the welding rod and the material being welded, thus bonding the objects together. Generally, they can be divided into two types according to the type of output power: AC power and DC power. Utilizing the principle of inductance, the inductance will generate a huge voltage change when it is switched on and off. The high-voltage electric arc generated when the positive and negative poles are momentarily short-circuited is used to melt the solder on the welding rod to achieve the purpose of atomic bonding.

[0003] Existing technologies, such as Chinese Patent Publication No. CN217096089U, disclose a welding machine with a cooling mechanism, including a welding machine body. The welding machine body has heat dissipation holes and protective covers on both sides. Each of the two protective covers has a heat dissipation opening in the middle of one side, with an intake fan installed in one opening and an exhaust fan installed in the other. A plug-in hole is provided on the upper side of the protective cover, and a sealing baffle is inserted inside the plug-in hole. Horizontal positioning sockets are installed on both sides of the upper end of the welding machine body, and one end of the sealing baffle can be inserted and positioned in the horizontal positioning socket. This invention, through the intake and exhaust fans installed inside the two heat dissipation openings respectively, accelerates air circulation inside the welding machine body, enabling rapid heat dissipation and greatly improving heat dissipation efficiency. Furthermore, the sealing baffle inserted in the plug-in hole inside the protective cover allows the heat dissipation openings to be sealed when not in use, facilitating dust and water protection and improving safety during use. However, the heat dissipation mechanism of this utility model is not easy to install or remove, which greatly increases the size and weight of the equipment. The dust accumulated inside is also not easy to clean, and it is not convenient to reuse it on welding machines of different sizes.

[0004] To address the issues of welding machine cooling mechanisms being difficult to install and remove and not suitable for welding machines of different sizes, existing welding machine cooling mechanisms are mostly fixed, making them inconvenient to disassemble and reassemble. This results in a significant increase in the size and weight of the equipment, and the accumulation of dust inside is also difficult to clean. Furthermore, different sizes of welding machines require different specifications of cooling mechanisms, making them inconvenient to reuse. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the cooling mechanism of the existing welding machine is not easy to install and remove and is not convenient to be used with welding machines of different sizes, and to propose a welding machine with a cooling mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a welding machine with a cooling mechanism, comprising a welding machine body, heat dissipation holes and a heat dissipation mechanism, wherein the heat dissipation holes are opened on the surface of the welding machine body and the heat dissipation mechanism is disposed on the surface of the welding machine body;

[0007] The heat dissipation mechanism includes a loading and unloading assembly, an adjustment assembly, and an auxiliary assembly. The loading and unloading assembly includes a mounting box and a heat dissipation box. The heat dissipation box is slidably connected to the inner wall of the mounting box. There are two sets of heat dissipation boxes. A filter screen is fixedly installed on the surface of each heat dissipation box. An intake fan is fixedly installed on the surface of one set of filter screens, and an exhaust fan is fixedly installed on the surface of the other set of filter screens. A plug rod is slidably connected to the inner wall of the welding machine body. An insertion hole is opened on the surface of the mounting box, and the plug rod is inserted into the surface of the insertion hole.

[0008] The adjustment assembly includes a bidirectional lead screw, which is rotatably connected to the inner wall of the mounting box, and the heat dissipation box is threadedly connected to the surface of the bidirectional lead screw.

[0009] Furthermore, a pull plate is fixedly connected to the surface of the insertion rod, and a spring is sleeved and connected to the surface of the insertion rod. One end of the spring is fixedly connected to the surface of the pull plate, and the other end of the spring is fixedly connected to the surface of the welding machine body.

[0010] Furthermore, the number of the insert rod, the insertion hole, the pull plate, and the spring are all in two sets, and the number of the insert rod, the insertion hole, and the spring in each set is two.

[0011] Furthermore, a worm gear is rotatably connected to the inner wall of the mounting box, and a worm wheel is fixedly connected to the surface of the bidirectional lead screw, with the surfaces of the worm gear and the worm wheel meshing together.

[0012] Furthermore, the auxiliary component includes an indicator block, which is fixedly connected to the surface of the mounting box. The surface of the heat sink is provided with scale lines, and the indicator block cooperates with the scale lines.

[0013] Furthermore, a handle is fixedly connected to the surface of the mounting box, and a sealing ring is fixedly connected to the surface of the heat dissipation box.

[0014] Furthermore, a knob is fixedly connected to the surface of the worm gear, and the surface of the knob is provided with anti-slip texture. The anti-slip texture consists of multiple sets and is evenly distributed around the circumference.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, a heat dissipation mechanism is set up. Pulling two sets of pull plates moves the two sets of plug rods away from each other and tightens the spring. Then, the mounting box is placed on the welding machine body, aligning the plug rods with the plug holes. The pull plates are released, and the plug rods return to their original positions and are inserted into the plug holes under the spring's rebound. The mounting box is then fixed on the welding machine body. Rotating the knob causes the worm gear to drive the worm wheel and the double-acting screw to rotate, thereby adjusting the distance between the two sets of heat dissipation boxes. This ensures that the sealing ring is pressed against the welding machine body, achieving a seal. The self-locking function of the worm gear and worm wheel maintains sufficient stability for the heat dissipation boxes, allowing them to adapt to welding machine bodies of different sizes. Subsequently, the intake fan and exhaust fan are started to accelerate air circulation and, together with the heat dissipation holes, achieve efficient heat dissipation. During disassembly, simply pull the two sets of pull plates to disengage the plug rods from the plug holes, and the entire heat dissipation mechanism can be removed.

[0017] 2. In this utility model, by setting a heat dissipation mechanism, the heat dissipation mechanism can be conveniently installed on the welding machine body when needed to improve the heat dissipation effect. When not needed, the heat dissipation mechanism can be removed to reduce the size and weight, and it is also convenient to clean the dust inside the heat dissipation mechanism. In addition, it can be adapted to the installation of welding machine bodies of different sizes and is easy to reuse, thus effectively improving the applicability of the equipment.

[0025] Please see Figures 1-5 The present invention provides a technical solution: a welding machine with a cooling mechanism, comprising a welding machine body 1, heat dissipation holes 2 and a heat dissipation mechanism 3, wherein the heat dissipation holes 2 are opened on the surface of the welding machine body 1, and the heat dissipation mechanism 3 is disposed on the surface of the welding machine body 1.

[0026] The specific setup and function of its heat dissipation mechanism 3 will be explained below.

[0027] In this embodiment: the heat dissipation mechanism 3 includes a loading and unloading assembly 31, an adjustment assembly 32 and an auxiliary assembly 33. The loading and unloading assembly 31 includes a mounting box 311 and a heat dissipation box 312. The heat dissipation box 312 is slidably connected to the inner wall of the mounting box 311. There are two sets of heat dissipation boxes 312. A filter screen 313 is fixedly installed on the surface of each heat dissipation box 312. An intake fan 314 is fixedly installed on the surface of one set of filter screens 313, and an exhaust fan 315 is fixedly installed on the surface of the other set of filter screens 313. A plug rod 316 is slidably connected to the inner wall of the welding machine body 1. An insertion hole 317 is opened on the surface of the mounting box 311. The plug rod 316 is inserted and connected to the surface of the insertion hole 317.

[0028] The adjustment assembly 32 includes a bidirectional lead screw 321, which is rotatably connected to the inner wall of the mounting box 311, and the heat dissipation box 312 is threadedly connected to the surface of the bidirectional lead screw 321.

[0029] The effects achieved by the above components are as follows: The mounting box 311, insertion rod 316, and insertion hole 317 are designed so that when the insertion rod 316 is inserted into the insertion hole 317, the mounting box 311 and the heat dissipation box 312 can be fixed onto the welding machine body 1, enabling quick installation. The heat dissipation box 312, intake fan 314, and exhaust fan 315 are designed so that when the mounting box 311 is installed on the welding machine body 1, the heat dissipation hole 2 is located inside the heat dissipation box 312. Activating the intake fan 314 and exhaust fan 315, in conjunction with the heat dissipation hole 2, can accelerate the airflow inside the welding machine body 1, achieving efficient heat dissipation. The filter screen 313 is designed to prevent dust and other contaminants from entering the heat dissipation box 312 and the welding machine body 1. The bidirectional lead screw 321 is designed so that when the bidirectional lead screw 321 rotates, it can drive the two sets of heat dissipation boxes 312 to move towards or away from each other, ensuring that both sets of heat dissipation boxes 312 can fit tightly against the welding machine body 1 when facing welding machine bodies 1 of different sizes.

[0030] Specifically, a pull plate 318 is fixedly connected to the surface of the insertion rod 316, and a spring 319 is sleeved and connected to the surface of the insertion rod 316. One end of the spring 319 is fixedly connected to the surface of the pull plate 318, and the other end of the spring 319 is fixedly connected to the surface of the welding machine body 1.

[0031] The effects achieved by the above components are as follows: the pull plate 318 is provided to facilitate pulling the insertion rod 316 to disengage it from the insertion hole 317; the spring 319 is provided to both lock the insertion rod 316 into the insertion hole 317 and to facilitate the reset of the insertion rod 316 by utilizing its rebound effect.

[0032] Specifically, there are two sets of each of the following components: insert rod 316, insert hole 317, pull plate 318, and spring 319. Each set contains two insert rods 316, insert holes 317, and springs 319.

[0033] The effect achieved by the above components is as follows: setting two sets of plug rods 316 and plug holes 317 is to ensure that both sets of plug rods 316 are disengaged from the plug holes 317 before the heat dissipation mechanism 3 can be removed, thus avoiding accidental contact. Setting two plug rods 316 and plug holes 317 for each set is to increase the stability of the fixation.

[0034] Specifically, a worm gear 322 is rotatably connected to the inner wall of the mounting box 311, and a worm wheel 323 is fixedly connected to the surface of the bidirectional lead screw 321. The surfaces of the worm gear 322 and the worm wheel 323 are meshed together.

[0035] The effect achieved by the above components is as follows: the worm 322 and worm wheel 323 are set so that when the worm 322 is rotated, the worm wheel 323 and the double-acting screw 321 can be rotated, and the self-locking function of the worm wheel 323 and worm 322 can be used to ensure that the two heat sinks 312 can maintain sufficient stability.

[0036] Specifically, the auxiliary component 33 includes an indicator block 331, which is fixedly connected to the surface of the mounting box 311. The surface of the heat sink 312 is provided with scale lines 332, and the indicator block 331 cooperates with the scale lines 332.

[0037] The effect achieved by the above components is as follows: the indicator block 331 and the scale line 332 are set to make it easy to intuitively display the moving distance of the two heat sinks 312 so as to make accurate adjustments.

[0038] Specifically, the surface of the mounting box 311 is fixedly connected to a handle 333, and the surface of the heat dissipation box 312 is fixedly connected to a sealing ring 334.

[0039] The effects achieved by the above components are as follows: the handle 333 is provided to facilitate gripping of the mounting box 311, and the sealing ring 334 is provided to increase the sealing between the heat dissipation box 312 and the welding machine body 1.

[0040] Specifically, a knob 335 is fixedly connected to the surface of the worm gear 322. The surface of the knob 335 is provided with anti-slip textures 336. The anti-slip textures 336 are in multiple sets and are evenly distributed around the circumference.

[0041] The effects achieved by the above components are as follows: the knob 335 is provided to facilitate the rotation of the worm gear 322, and the anti-slip texture 336 is provided to increase friction and prevent slippage when rotating the knob 335.

[0042] Working principle: By setting up the heat dissipation mechanism 3, pulling the two sets of pull plates 318 causes the two sets of insertion rods 316 to move away from each other and tightens the spring 319. Then, the mounting box 311 is placed on the welding machine body 1, aligning the insertion rods 316 with the insertion holes 317. The pull plates 318 are released, and under the rebound action of the spring 319, the insertion rods 316 return to their original position and insert into the insertion holes 317. The mounting box 311 is then fixed on the welding machine body 1. Rotating the knob 335 causes the worm gear 322 to drive the worm wheel 323 and the double-acting screw 321 to rotate, thereby adjusting the... The distance between the two sets of heat dissipation boxes 312 is reduced so that the sealing ring 334 is pressed against the welding machine body 1 to achieve a seal. The self-locking function of the worm gear 323 and worm 322 is used to maintain sufficient stability of the heat dissipation box 312 so as to adapt to welding machine bodies 1 of different sizes. Then the intake fan 314 and exhaust fan 315 are started to accelerate air circulation and work with the heat dissipation hole 2 to achieve efficient heat dissipation. When disassembling, simply pull the two sets of pull plates 318 to disengage the plug rod 316 from the plug hole 317 and the entire heat dissipation mechanism 3 can be removed.

[0043] By setting up the heat dissipation mechanism 3, it can be conveniently installed on the welding machine body 1 when needed to improve the heat dissipation effect. When not needed, the heat dissipation mechanism 3 can be removed to reduce the size and weight, and it is also convenient to clean the dust inside the heat dissipation mechanism 3. In addition, it can be adapted to the installation of welding machine bodies 1 of different sizes, and is easy to reuse, thus effectively improving the applicability of the equipment.
