Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electric welding machines, and relates to an electric welding machine, and particularly to an electric welding machine with protective functions. Background Technology
[0002] An electric welding machine uses the high-temperature electric arc generated when the positive and negative electrodes are short-circuited for a moment to melt the welding material on the welding rod and the material to be welded, so that the objects in contact are joined together. Its structure is very simple.
[0003] When working with an electric welding machine, people wear face shields to protect their eyes and face. However, the welding machine can easily splatter small, high-temperature particles that can burn exposed skin. Existing welding torches have filters, but these filters have a small protection range and cannot filter strong light when the angle and position of the welding torch change, causing the naked eye to see the sparks directly during welding. At the same time, the filters are prone to accumulating metal particles during long-term operation and need to be replaced in a timely manner.
[0004] For example, a welding machine with protective function, as described in application number CN202320180210.8, includes a welding machine body, a welding gun head mounted on the back of the welding machine body, a filter plate mounted on the welding gun head, the filter plate being fixed to the welding gun bracket by bolts, protective plates mounted on both sides of the welding machine body, support guide rods mounted on both sides of the welding machine body by bolts, a support collar fixed to the outer surface of the support guide rod, a connecting collar mounted on the outside of the support guide rod, a return spring mounted between the connecting collar and the support collar, and the support guide rod located inside the return spring.
[0005] The above-mentioned patent has a limited protective range of the filter plate. As the welding position changes, the strong light from the welding point can easily shine directly into the naked eye. At the same time, the welding gun installed outside the welding machine is prone to collisions, and the filter plate, as a vulnerable part, is easily damaged. In addition, the bolt installation requires manual tightening of the bolts, which is time-consuming and laborious. Utility Model Content

Detailed Implementation
[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0023] like Figures 1 to 6 As shown, this utility model can be implemented through the following embodiments: A welding machine with a filter plate 5 includes a body 1 and a welding torch 2. The body 1 is provided with a storage groove 11, the storage groove 11 is provided with a rotating part 111, the rotating part 111 is equipped with a rotating door 3, the welding torch 2 is installed on the body 1, the welding torch 2 is provided with a fixing ring 21, the fixing ring 21 is provided with an installation groove 211, the installation groove 211 is installed with a rotating rod 4, the filter plate 5 is slidably installed between adjacent rotating rods 4, the rotating rod 4 is provided with slots 41 on both sides, the filter plate 5 is provided with a frame 51, the frame 51 is provided with a locking block 511, the fixing ring is provided with a protrusion 212, and the frame 51 is provided with a groove 512.
[0024] The storage slot 11 is used to store the filter plate 5 and the welding torch 2. A rotating part 111 is provided on the storage slot 11. The rotating part 111 cooperates with the rotating door 3, so that the rotating door 3 can be opened and closed by rotation. The fixing ring 21 is used to install the rotating rod 4, and the rotating rod 4 rotates relative to the welding torch 2 to realize the folding of the rotating rod 4. The filter plate 5 is slidably connected to the rotating rod 4, which facilitates the loading and unloading of the filter plate 5. A spring is provided between the locking block 511 and the frame 51. The spring acts on the locking block 511, so that the locking block 511 can move in and out of the frame 51 and ensure that the locking block 511 can be locked into the locking groove 41. The protrusion 212 cooperates with the groove 512 to position the filter plate 5, restrict the axial sliding of the filter plate 5, reduce the pressure of the locking block 511, and reduce the impact on the sliding ring 22 and the connecting rod 6.
[0025] like Figure 2As shown, the fixed ring 21 extends with a guide section 213, and a sliding ring 22 is mounted on the guide section 213. An extension rod 221 is mounted on the sliding ring 22, and the rotating rod 4 is connected to the extension rod 221. The sliding ring 22 slides on the guide section 213, and the extension rod 221 controls the folding and unfolding of the rotating rod 4, eliminating the need for the user to manually fix or fold the rotating rod 4, thus reducing the unfolding time of the welding torch 2. The guide section 213 guides the sliding direction of the sliding ring 22, preventing the extension rod 221 from bearing torque due to the rotation of the sliding ring 22, which could cause the connection between the extension rod 221 and the rotating rod 4 to loosen.
[0026] like Figures 3 to 5 As shown, grooves 512 are provided on both sides of the rotating rod 4, and corresponding protrusions 61 are provided on both sides of the connecting rod 6. The grooves 512 and protrusions 61 cooperate to realize the mutual rotation between the rotating rod 4 and the connecting rod 6, so that when the sliding ring 22 slides, the rotating rod 4 can respond to the sliding ring 22 in a timely manner.
[0027] like Figure 2 and Figure 3 As shown, a spiral block 7 is installed on the sliding ring 22, and a blind hole 23 is provided on the welding torch 2. The spiral block 7 and the sliding ring 22 are connected by threads, and a groove 512 is provided on the top. The groove 512 is used to rotate the spiral block 7 by a screwdriver or wrench. A round rod is provided under the spiral block 7. The round rod is inserted into the blind hole 23 of the welding torch 2 to limit the displacement of the sliding block and prevent the rotating rod 4 from being pulled by the extension rod 221 due to vibration and the weight of the filter plate 5 during operation, which would cause the sliding ring 22 to slide on the welding torch 2, resulting in noise or the filter plate 5 falling off.
[0028] like Figure 2 and Figure 3 As shown, the welding torch 2 is equipped with a fixing ring 24, which has a fixing groove 241. A locking block 242 is installed in the fixing groove 241. The fixing ring 24 is used to store and fix the folded rotating rod 4, preventing the sliding ring 22 from accidentally sliding and causing the rotating rod 4 to stand up, thus facilitating the storage of the welding torch 2. The fixing groove 241 is used to accommodate the rotating rod 4, and allows the locking groove 41 on the rotating rod 4 to engage with the locking block 242. A spring is installed between the locking block 242 and the fixing ring 24. The spring facilitates the locking block 242 to create space for the rotating rod 4 to engage with the fixing groove 241 and engage with the locking groove 41.
[0029] like Figure 3As shown, a pressure block 8 is installed in the slot 41. The pressure block 8 is connected to a movable rod 81, and the movable rod 81 is threadedly connected to the rotating rod 4. A fixing plate 811 is provided on the top of the movable rod 81. The fixing plate 811 allows the user to apply force to rotate it. The movable rod 81 is fixedly connected to the fixing plate 811, and the movable rod 81 and the pressure block 8 can rotate relative to each other. This allows the pressure block 8 to not obstruct the rotation of the movable rod 81 when the movable rod 81 moves the pressure block 8 downward through the threaded connection. The pressure block 8 enters the slot 41 and squeezes out the card block in the slot 41, increasing the speed of disassembling and assembling the filter plate 5 and facilitating the storage of the rotating rod 4 and the welding torch 2.
[0030] The working principle of this utility model is as follows: The welding torch 2 is taken out of the receiving slot 11 and connected to the welding machine. By rotating the fixed plate 811, the movable rod 81 is rotated, causing the pressure block 8 to move downwards. The downward-moving pressure block 8 pushes open the second locking block 242 in the fixed slot 241, causing the second locking block 242 to disengage from the slot 41. After the rotating rod 4 is pushed outwards from the welding torch 2, the sliding ring 22 is pulled, causing the sliding ring 22 to pull the rotating rod 4 through the connecting rod 6, thus causing the rotating rod 4 to rotate. The rotating rod 4 is perpendicular to the central axis of the welding torch 2. The threaded block is screwed into the welding torch 2 by rotating the screwdriver, so that the limiting rod enters the welding torch 2 and the sliding block is fixed to the welding torch 2. The filter plate 5 is inserted into the rotating rod 4. The locking block 511 of the filter plate 5 is locked into the slot 41 by the action of the spring, so as to realize the installation of the filter plate 5. Conversely, the fixing plate 811 is rotated, and the locking block 511 is squeezed out of the slot 41 by the pressure block 8. Then the above steps are reversed. Example
[0031] like Figure 4 As shown, a latch 43 is provided at the top of the rotating rod 4, and a first latch 82 and a second latch 83 are provided on the movable rod 81. The first latch 82 and the second latch 83 are used to cooperate with the latch 43 to fix the position of the movable rod 81 and the pressure block 8.
[0032] The working principle of this embodiment is as follows: When the welding gun 2 is working, the first hook 82 is inserted into the slot 43. The pressure block 8 is disengaged from the slot 41 due to the length limitation of the movable rod 81. When the rotating rod 4 is being stored, the first hook 82 is pinched and the movable rod 81 is pushed down from the fixed plate 811, squeezing the first block 511 out of the slot 41. Then the filter plate 5 is taken out, and the sliding ring 22 is pushed to move towards the fixed ring 21, causing the extension rod 221 to drive the rotating rod 4 to retract. Pressing the top of the rotating rod 4 causes the second block 242 of the fixed ring 24 to be inserted into the slot 41 of the rotating rod 4.
