DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The core of the utility model is to provide a welding gun protection device, which can prevent the welding gun head of the welding gun from being contaminated.

[0039] Please refer to Figure 1 and Figure 2 The utility model provides a welding gun protection device, including a bracket 1, a first welding gun 2, a first slag stop plate 3, a second slag stop plate 4 and a driving device. The bracket 1 mainly plays a supporting role and is used to set the first welding gun 2, the first slag stop plate 3, the second slag stop plate 4 and the driving device. The first welding gun 2 can be slidably arranged on the bracket 1 along a preset direction; the first slag stop plate 3 and the second slag stop plate 4 can be rotatably arranged on the bracket 1; the driving device is arranged on the bracket 1 and is respectively connected to the first slag stop plate 3 and the second slag stop plate 4, and is used to drive the first slag stop plate 3 and the second slag stop plate 4 to open (such as when the first welding gun 2 is extended). Figure 1 As shown), and when the first welding gun 2 is retracted, the first slag stop plate 3 and the second slag stop plate 4 are driven to close (as shown Figure 2 As shown in the figure), when the first slag stop plate 3 and the second slag stop plate 4 are opened, the welding gun head 21 of the first welding gun 2 can pass between the first slag stop plate 3 and the second slag stop plate 4, and when the first slag stop plate 3 and the second slag stop plate 4 are closed, the first slag stop plate 3 and the second slag stop plate 4 each abut one end close to the welding gun head 21 to form a closed body.

[0040] It can be understood that the first welding gun 2 can be slidably arranged on the bracket 1 along a preset direction so that the first welding gun 2 can be retracted. When the first welding gun 2 is extended, it is used for welding. By adjusting the extension amount of the first welding gun 2, the first welding gun 2 can have different heights, which is conducive to welding positions to be welded at different heights; when the first welding gun 2 is retracted, it is in a non-working state.

[0041] That is to say, when it is necessary to use the first welding gun 2 for welding, the first welding gun 2 is extended, and at the same time, the first slag stop plate 3 and the second slag stop plate 4 are driven to open by the driving device, so that the first slag stop plate 3 and the second slag stop plate 4 make way for the extension of the first welding gun 2, so that the first welding gun 2 can be extended from between the first slag stop plate 3 and the second slag stop plate 4, so that the first welding gun 2 can enter the working state for welding; when the welding is completed, the first welding gun 2 is retracted, and at the same time, the first slag stop plate 3 and the second slag stop plate 4 are driven to close by the driving device. , so that after the first welding gun 2 is fully retracted, the first slag stop plate 3 and the second slag stop plate 4 are in a closed state. At this time, the first slag stop plate 3 and the second slag stop plate 4 are respectively abutted against one end of the welding gun head 21 close to the first welding gun 2 to form a closed body, and the welding gun head 21 is enclosed in the space between the first slag stop plate 3 and the second slag stop plate 4. The first slag stop plate 3 and the second slag stop plate 4 are used to protect the welding gun head 21 to prevent the welding gun head 21 from being contaminated by dust, impurities or splashes, thereby avoiding the contaminants from affecting the welding quality of the first welding gun 2.

[0042] It should be noted that the present embodiment does not limit the specific structure of the driving device, as long as it can drive the first slag stop plate 3 and the second slag stop plate 4 to open or close respectively.

[0043] In some embodiments, the driving device includes a power source 5, a first transmission mechanism and a second transmission mechanism. The power source 5 is used to output telescopic movement along a preset direction; the first transmission mechanism is connected between the power source 5 and the first slag stop plate 3, and is used to drive the first slag stop plate 3 to open or close; the second transmission mechanism is connected between the power source 5 and the second slag stop plate 4, and is used to drive the second slag stop plate 4 to open or close. That is to say, this embodiment adopts the same power source 5, and transmits the power of the power source 5 to the first slag stop plate 3 and the second slag stop plate 4 through two transmission mechanisms (the first transmission mechanism and the second transmission mechanism), respectively, and converts the telescopic movement along the preset direction output by the power source 5 into the rotation of the first slag stop plate 3 and the second slag stop plate 4, so that the first slag stop plate 3 and the second slag stop plate 4 are opened or closed at the same time. The power source 5 is saved, and the cost is saved.

[0044] It should be noted that the present embodiment does not limit the specific implementation of the power source 5, as long as it can output telescopic movement along a preset direction. In some embodiments, the power source 5 is a cylinder. In addition, the present embodiment does not limit the specific structure of the first transmission mechanism and the second transmission mechanism, as long as they can transmit the power of the power source 5 to the first slag stop plate 3 and the second slag stop plate 4 respectively.

[0045] Please refer to Figure 3 In some embodiments, the first transmission mechanism includes a first push rod 61, a first rocker arm 62 and a first elastic member 63, the first push rod 61 is connected to the power source 5; the first rocker arm 62 is connected to the first slag stopper 3, and a cam pair is formed between the first rocker arm 62 and the first push rod 61, so that when the power source 5 drives the first push rod 61 to extend, the first push rod 61 pushes the first rocker arm 62 to rotate, so as to drive the first slag stopper 3 to open; the first elastic member 63 is connected between the first rocker arm 62 and the bracket 1, and is used to provide a closing elastic force for the first slag stopper 3 when the power source 5 drives the first push rod 61 to retract. That is to say, when the first welding gun 2 is extended, the power source 5 drives the first push rod 61 to extend, so that under the side effect of the cam between the first push rod 61 and the first swing rod 62, the first push rod 61 pushes the first swing rod 62 to swing, and since the first swing rod 62 is connected to the first slag stop plate 3 as a whole, the first swing rod 62 drives the first slag stop plate 3 to rotate, so that the first slag stop plate 3 is opened, and in this process, the first elastic member 63 produces elastic deformation to store elastic energy; when the first welding gun 2 is retracted, the power source 5 drives the first push rod 61 to retract, so that the first slag stop plate 3 is reset to a closed state under the action of the elastic force of the first elastic member 63. It can be seen that this embodiment uses the cam pair between the first swing rod 62 and the first push rod 61 to convert the movement of the first push rod 61 along the preset direction into the rotation of the first slag stop plate 3, and the structure is simple and ingenious.

[0046] Please refer to Figure 4In some embodiments, the second transmission mechanism includes a second push rod 71, a second rocker arm 72 and a second elastic member 73, the second push rod 71 is connected to the power source 5; the second rocker arm 72 is connected to the second slag stop plate 4, and a cam pair is formed between the second rocker arm 72 and the second push rod 71, so that when the power source 5 drives the second push rod 71 to extend, the second push rod 71 pushes the second rocker arm 72 to rotate, so as to drive the second slag stop plate 4 to open; the second elastic member 73 is connected between the second rocker arm 72 and the bracket 1, and is used to provide a closing elastic force for the second slag stop plate 4 when the power source 5 drives the second push rod 71 to retract. That is to say, when the first welding gun 2 is extended, the power source 5 drives the second push rod 71 to extend, so that under the side effect of the cam between the second push rod 71 and the second swing rod 72, the second push rod 71 pushes the second swing rod 72 to swing, and since the second swing rod 72 is connected to the second slag stop plate 4 as a whole, the second swing rod 72 drives the second slag stop plate 4 to rotate, so that the second slag stop plate 4 is opened, and in this process, the second elastic member 73 produces elastic deformation to store elastic energy; when the first welding gun 2 is retracted, the power source 5 drives the second push rod 71 to retract, so that the second slag stop plate 4 is reset to a closed state under the action of the elastic force of the second elastic member 73. It can be seen that this embodiment uses the cam pair between the second swing rod 72 and the second push rod 71 to convert the movement of the second push rod 71 along the preset direction into the rotation of the second slag stop plate 4, and the structure is simple and ingenious.

[0047] Furthermore, please combine Figure 3 and Figure 4In some embodiments, the bracket 1 includes two oppositely arranged side walls, a rotating shaft 11 is connected between the two side walls, the first rocker arm 62, the second rocker arm 72, and the second slag stop plate 4 are all rotatably connected to the rotating shaft 11, and the first transmission mechanism also includes a connecting rod 64 rotatably connected to the rotating shaft 11, the connecting rod 64 is connected to the first slag stop plate 3, and the connecting rod 64 and the first rocker arm 62 are respectively located at both ends of the rotating shaft 11. That is to say, in this embodiment, the first swing rod 62, the second swing rod 72, the second slag stop plate 4 and the connecting rod 64 respectively form a rotation pair with the rotating shaft 11, so that the first swing rod 62, the second swing rod 72, the second slag stop plate 4 and the connecting rod 64 can rotate relative to the rotating shaft 11 respectively; in addition, the first swing rod 62 and the connecting rod 64 are arranged opposite to each other, and both are respectively located at the two ends of the rotating shaft 11, and both are connected to the first slag stop plate 3. When the first push rod 61 pushes the first swing rod 62 to rotate, the first swing rod 62 drives the first slag stop plate 3 and the connecting rod 64 to rotate around the rotating shaft 11 as a whole, which can ensure the stability of the movement of the first slag stop plate 3. When the second push rod 71 pushes the second swing rod 72 to rotate, the second swing rod 72 and the second stop plate are both rotated around the rotating shaft 11 under the drive of the second swing rod 72. The structure provides a specific arrangement of the first rocker arm 62, the second rocker arm 72, the first slag stop plate 3 and the second slag stop plate 4, which can ensure the smooth movement of the first slag stop plate 3 and the second slag stop plate 4, and the first rocker arm 62, the second rocker arm 72, the second slag stop plate 4 and the connecting rod 64 share the same rotating shaft 11, making the structure simple and compact.

[0048] For further information, please refer to Figure 3 and Figure 4In some embodiments, the power source 5 is connected to the push plate 8, the first welding gun 2 passes through the push plate 8, the first push rod 61 and the second push rod 71 are respectively arranged on both sides of the push plate 8, and the first push rod 61 and the second push rod 71 are respectively located on the outside of the two side walls of the bracket 1, the first rocker arm 62 and the second rocker arm 72 are respectively located on the outside of the two side walls, and the connecting rod 64 is located on the inner side of the side wall corresponding to the second rocker arm 72. That is to say, in this embodiment, the first push rod 61 and the second push rod 71 are respectively connected to the power source 5 through the push plate 8, and the push plate 8 plays a role of switching, which is conducive to placing the first push rod 61 and the second push rod 71 in a suitable position. The first push rod 61 and the second push rod 71 are respectively arranged on both sides of the push plate 8, so that the first push rod 61 and the second push rod 71 are conveniently connected to the push plate 8; and the first push rod 61 and the second push rod 71 and the first swing rod 62 and the second swing rod 72 are respectively located on the outside of the two side walls, and the layout is reasonable, so as to avoid the first push rod 61, the second push rod 71, the first swing rod 62 and the second swing rod 72 occupying the space between the two side walls, which is conducive to maximizing the size of the first slag stop plate 3 and the second slag stop plate 4 located between the two side walls, and playing a better protective role. In addition, the connecting rod 64 is located on the inner side of the side wall corresponding to the second swing rod 72, which is conducive to placing the connecting rod 64 and the first swing rod 62 at both ends of the rotating shaft 11, respectively, and playing a role in stabilizing the support of the first slag stop plate 3.

[0049] In addition, if Figure 3 As shown, in some embodiments, the first swing rod 62 includes a cam rod portion 621 and a transfer rod portion 622, and an angle is formed between the two. The cam rod portion 621 and the first push rod 61 form a cam pair, and the transfer rod portion 622 is connected to the first slag stopper plate 3. In other words, the cam rod portion 621 and the transfer rod portion 622 form a V-shaped structure, which is conducive to the first swing rod 62 and the first push rod 61 forming a cam pair. At the same time, through the angle between the cam rod portion 621 and the transfer rod portion 622, the first slag stopper plate 3 can have a suitable position, which facilitates the connection of the first swing rod 62 with the first push rod 61 and the first slag stopper plate 3.

[0050] It should be noted that in the above-mentioned embodiments, the specific shapes of the first slag stop plate 3 and the second slag stop plate 4 are not limited, as long as they can form a closed body to protect the welding gun head 21 when both are closed. In some embodiments, the first slag stop plate 3 and the second slag stop plate 4 are both arc-shaped plates, and the arc-shaped inner concave surfaces of the two are opposite. This can increase the space between the first slag stop plate 3 and the second slag stop plate 4, so as to better accommodate the welding gun head 21.

[0051] In addition, please combine Figure 1-Figure 3In some embodiments, the bracket 1 is provided with a second welding gun 9, and the second welding gun 9 is located on one side of the first welding gun 2; the second slag stop plate 4 is located between the first welding gun 2 and the second welding gun 9, and the area of ​​the second slag stop plate 4 is smaller than the area of ​​the first slag stop plate 3, and the curvature of the second slag stop plate 4 is smaller than the curvature of the first slag stop plate 3. That is to say, in this embodiment, the first welding gun 2 and the second welding gun 9 form a composite welding gun, and the two coordinate and cooperate with each other, which is conducive to automatic welding, can improve welding efficiency, and can ensure the welding quality at the transition position of the joint. Since the second slag stop plate 4 is located between the first welding gun 2 and the second welding gun 9, and the space between the first welding gun 2 and the second welding gun 9 is often relatively limited, in this embodiment, by making the area of ​​the second slag stop plate 4 smaller than the area of ​​the first slag stop plate 3, and the curvature of the second slag stop plate 4 is smaller than the curvature of the first slag stop plate 3, the second slag stop plate 4 is more suitable for the space between the first welding gun 2 and the second welding gun 9, and at the same time, the first slag stop plate 3 has a relatively large area and a relatively large curvature, so that the space between the first slag stop plate 3 and the second slag stop plate 4 is increased, and the protection effect is improved.

[0052] Furthermore, please combine Figure 1-Figure 3 In some embodiments, the first welding gun 2 is connected to the power source 5. That is, the first welding gun 2, the first slag stop plate 3 and the second slag stop plate 4 share the same power source 5, so that when the power source 5 outputs the telescopic movement, the first welding gun 2, the first slag stop plate 3 and the second slag stop plate 4 are linked, that is, the opening and closing movements of the first slag stop plate 3 and the second slag stop plate 4 are linked with the telescopic movement of the first welding gun 2, which is beneficial to saving the power source 5 and conveniently controlling the timing of the movements of the first welding gun 2, the first slag stop plate 3 and the second slag stop plate 4.

[0053] It should also be noted that, in this specification, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0054] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
