Description

Technical Field

[0001] The utility model relates to the technical field of welding protection equipment, and specifically relates to a protection mechanism for a welding machine. Background Technique

[0002] In the field of welding processing, the protection mechanism is a key component to ensure operation safety and process visibility. In the prior art, a protective cover made of light-shielding glass material is used to cover the welding area, and physical isolation is used to block flying sparks, molten slag and welding fumes, avoiding direct contact between operators and high-temperature radiation and harmful particles.

[0003] However, due to the large amount of solid particles in the flue gas, when the flue gas rising due to heat contacts the protective cover, the solid particles in the flue gas will adhere to the inner side of the protective cover, resulting in a decrease in the transparency of the protective cover, and further affecting subsequent operators' observation of the welding area through the protective cover. At the same time, flying sparks or high-temperature molten metal will be generated during the welding process. When these sparks impact the surface of the protective cover, local burns or microcracks will be caused, and long-term accumulation will reduce the transparency. In view of this, we propose a protection mechanism for a welding machine. Content of the Utility Model

[0004] The purpose of the utility model is to provide a protection mechanism for a welding machine, which solves the problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] The protection mechanism includes a protection frame, the protection frame is slidably connected to the side of the frame, a protective cover is fixedly connected in the middle of the protection frame, and ventilation holes are provided inside the protection frame.

[0009] Preferably, the protection frame is of a hollow structure, the ventilation holes are interconnected with the inside of the protection frame, and the protection frame includes a support frame slidably connected to the frame and a mounting frame fixedly connected to the support frame.

[0010] Preferably, the support frame is of a "C" - shaped structure, the mounting frame is of an arc - shaped structure, and the structure of the protective cover corresponds to the structure of the mounting frame.

[0013] Preferably, a fan is fixedly connected inside the frame, and a connecting pipe is connected to both ends of the fan. A sleeve is fitted on the outside of the connecting pipe, and a movable plate is fixedly connected to the outside of the sleeve.

[0015] By employing the above technical solution, this utility model provides a protective mechanism for welding machines that has at least the following beneficial effects:

[0016] (1) This utility model uses the ventilation holes as the air inlet and exhaust end respectively, thereby forming a flowing gas barrier between the ventilation holes. This can guide and collect the fumes generated during the welding process. At the same time, the flowing gas can block the splashing sparks. Before the sparks come into contact with the protective cover, the airflow reduces the temperature of the spark surface, thus reducing the damage to the protective cover. The flowing gas can also blow the lighter sparks away from the protective cover. By reducing the damage to the protective cover or reducing the amount of fumes adhering to the surface of the protective cover, the service life of the protective cover is increased, and the frequency of maintenance or cleaning of the protective cover is reduced.

[0017] (2) The present invention can switch the collection structure through the set switching collection mechanism, so that the protective cover can collect the welding fumes through different structures when in use or waiting, thereby reducing the obstruction of the operator's vision by the fumes.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] A protective mechanism for welding machines, such as Figures 1-3 , Figure 5 As shown, it includes a frame 1; the frame 1 is equipped with a collection mechanism 3, which can collect the fumes generated during the welding process, reduce the obstruction of the operator's vision by the fumes, and at the same time avoid the harm of toxic fumes to the operator.

[0028] Specifically, the collection mechanism 3 includes a column 31, which is fixedly connected to the top of the frame 1. The column 31 has a hollow structure and a collection port 32 is opened on the side of the column 31. A collection cover 33 is fixedly connected to the collection port 32. The column 31 can be used as a support structure to support the parts to be welded, or as a suspension structure for the welding torch. The hollow column 31 can absorb the fumes generated during the welding process through the collection port 32 on the side, reducing the amount of fumes that diffuse into the operating environment, thereby reducing the obstruction of fumes to the operators.

[0029] In addition, a fan 35 is fixedly connected inside the frame 1, and connecting pipes 36 are connected to both ends of the fan 35. An exhaust pipe 34 is fixedly connected inside the frame 1 and is fixedly connected to the column 31. The exhaust pipe 34 and the column 31 are interconnected. The fan 35 draws air out of the column 31 through the connecting pipe 36 and the exhaust pipe 34, creating a negative pressure environment inside the column 31, thereby realizing the collection of smoke. At the same time, the connecting pipe 36 is equipped with a filter structure to filter the collected smoke and prevent particles in the smoke from entering the fan 35 and causing blockage of the fan 35.

[0030] Embodiment 2

[0031] As Figures 1-4 shown, on the basis of Embodiment 1, a protection mechanism 2 is provided on the frame 1. The protection mechanism 2 can protect the operator and block the metal sparks or flying metal debris generated during the welding process.

[0032] In this embodiment, the protection mechanism 2 includes a protection frame 21. The protection frame 21 is slidably connected to the side of the frame 1. A protective cover 22 is fixedly connected in the middle of the protection frame 21. The protection frame 21 can support the protective cover 22, thereby shielding the welding area and blocking the flying metal sparks during the welding process. The protective cover 22 is made of light-shielding glass material. The protective cover 22 can filter the invisible light during the welding process. The slidably connected protection frame 21 can adjust the position of the protective cover 22 to open the welding area, facilitating the picking and placing operations of the parts or welded products on the frame 1.

[0033] Furthermore, the protection frame 21 includes a support frame 24 slidably connected to the frame 1 and a mounting frame 25 fixedly connected to the support frame 24. The support frame 24 is in a "U" - shaped structure, and the mounting frame 25 is in an arc - shaped structure. The structure of the protective cover 22 corresponds to the structure of the mounting frame 25. The "U" - shaped support frame 24 can cooperate with the fan 35, so that both ends of the support frame 24 can cover both ends of the fan 35. The arc - shaped protective cover 22 is convenient for the use of workers with different heights.

[0034] It should be noted that a sleeve 37 is sleeved outside the connecting pipe 36. A moving plate 38 is fixedly connected to the outside of the sleeve 37. One side of the moving plate 38 is in an arc - shaped structure. A buffer spring is fixedly connected to the moving plate 38, and the other end of the buffer spring is fixedly connected to the frame 1. The buffer spring is sleeved outside the connecting pipe 36. The structure of the sleeve 37 can slide and adjust outside the connecting pipe 36, enabling the connecting pipe 36 to be interconnected with the exhaust pipe 34 through the sleeve 37 or forming a section of interval between the connecting pipe 36 and the exhaust pipe 34 when the sleeve 37 is opened, facilitating the insertion of the support frame 24. The moving plate 38 with an arc - shaped edge can cooperate with the support frame 24. When the support frame 24 moves and inserts, the arc - shaped edge can push the moving plate 38 to move and open. The buffer spring structure can reset the moving plate 38. After the support frame 24 is pulled out, the buffer spring can push the moving plate 38 and the sleeve 37 to reset by elasticity.

[0035] Based on this, the protective frame 21 has a hollow structure, and the support frame 24 has through holes 26 that are interconnected with the interior of the support frame 24. The through holes 26 correspond to the positions of the sleeve 37. The inner side of the protective frame 21 has ventilation holes 23 that are interconnected with the interior of the protective frame 21. The hollow structure of the protective frame 21 can cooperate with the through holes 26 and the ventilation holes 23 to connect the fan 35 with the ventilation holes 23. At the same time, the U-shaped support frame 24 can connect the two through holes 26 to the two ends of the fan 35 respectively. Thus, the ventilation holes 23 on the protective frame 21 can form an air inlet and an exhaust end respectively, and the area between the two rows of ventilation holes 23 forms an airflow barrier to block the smoke or sparks generated during the welding process.

[0036] In the operation of this protective mechanism for a welding machine, the fan 35 runs continuously. When the protective cover 22 is not in use, the moving plate 38 moves away from the fan 35 under the elastic action of the buffer spring, and the sleeve 37 connects the connecting pipe 36 and the exhaust pipe 34. At this time, the fan 35 continuously draws the fumes generated during the welding process into the column 31. After the solid particles in the fumes are filtered by the filter structure, the extracted gas is discharged from the other end of the fan 35, thereby reducing the interference of fumes on the operator. When the protective frame 21 moves to the fan 35, the support frame 24 drives the moving plate 38 to move away from the exhaust pipe 34 through the edge of the arc-shaped moving plate 38. The connecting pipe 36 then separates from the exhaust pipe 34. At the same time, as the support frame 24 continues to move, it moves between the connecting pipe 36 and the exhaust pipe 34. The support frame 24 is connected to the connecting pipe 36 through the through hole 26. Both ends of the fan 35 are connected to the ventilation holes 23 through the through holes 26 respectively. At this time, the fan 35 draws the air between the protective cover 22 and the frame 1 into the protective frame 21. After the air is filtered by the filter structure, it is discharged through the vent 23 on the other side by the drive of the fan 35, thus forming an airflow barrier on one side of the protective cover 22 to block the fumes or welding sparks during the welding process and avoid affecting the protective cover 22.
