[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] like Figure 1-4 As shown, the present application relates to a welding protection device. The welding protection device includes a base 10. Base 10 is a bottom support seat that provides excellent bottom fixation and support. It also provides a suitable place for assembly of other components, thereby achieving good component coordination. Preferably, base 10 is made of section steel, which provides excellent physical properties and ensures structural stability.

[0032] A plurality of feeding mechanisms 20 are relatively arranged on the upper surface of the base 10; by assembling a plurality of feeding mechanisms 20 on the base 10, a good automatic feeding effect can be achieved, thereby achieving the effect of improving production efficiency; at the same time, by providing the feeding mechanism 20, the product to be processed can be transported from the initial position to the designated position, thereby achieving the effect of facilitating other operations. In the present application, the running direction of the feeding mechanism 20 is the direction of feeding; it can achieve the effect of increasing the feeding stroke, thereby achieving the effect of improving space utilization. It should be understood that by relatively arranging a plurality of feeding mechanisms 20 on the base 10, the effect of synchronous feeding can be achieved. Preferably, the number of the plurality of feeding mechanisms 20 is two; it can achieve the effect of synchronous product transportation. Of course, the specific number of uses can be adjusted according to the use requirements, and is not limited in the present application.

[0033] A plurality of feeding mechanisms 30 are respectively connected to the movable ends of the two feeding mechanisms 20; by respectively arranging the feeding mechanisms 30 on the plurality of feeding mechanisms 20, a good material feeding effect can be achieved, thereby achieving the effect of lateral position adjustment, and then adjusting the position of the product to the desired position, and finally achieving the effect of facilitating welding. Preferably, the number of the plurality of feeding mechanisms 30 is two groups, wherein one group is composed of relatively arranged feeding mechanisms 30, and the feeding directions are in the same direction; the feeding directions of the other adjacent group of feeding mechanisms 30 are in the same direction, and the feeding directions of the two adjacent groups of feeding mechanisms 30 are opposite; position adjustment in two directions can be achieved, thereby achieving the effect of flexible adjustment. Of course, the specific number of uses can be adjusted according to the use requirements, and is not limited in this application.

[0034] The extension plate 40 is horizontally arranged between the base 10 and the feeding mechanism 20; by assembling the extension plate 40 on the base 10, the contact area can be increased, thereby achieving a good assembly effect; at the same time, it can also facilitate the stable installation of other components, thereby improving the stability of the structure.

[0035] The first lifting mechanism 50 is perpendicularly mounted on the upper surface of the extension plate 40 and is located in the direction extending from the centerline between the plurality of feeding mechanisms 20. Assembling the first lifting mechanism 50 on the upper surface of the extension plate 40 enables a good lifting effect, thereby enabling the welding position to be adjusted, thus meeting the needs of various usage scenarios. Furthermore, positioning the first lifting mechanism 50 between the plurality of feeding mechanisms 20 facilitates centering.

[0036] Several second lifting mechanisms 60 are symmetrically arranged on the extension plate 40 with respect to the first lifting mechanism 50 and are located outside the feed mechanisms 30. The arrangement of these second lifting mechanisms 60 on the upper surface of the extension plate 40 and outside the feed mechanisms 30 facilitates effective auxiliary positioning, ensuring that the products to be welded are positioned at the same level. This also improves product placement stability, thereby ensuring improved welding accuracy. Preferably, there are two second lifting mechanisms 60, which improves product placement stability. Of course, the specific number of these mechanisms can be adjusted based on usage requirements and is not limited in this application.

[0037] The protective cover 70 is connected to the first lifting mechanism 50. The protective cover 70 provided on the first lifting mechanism 50 effectively contains the welding gas, thereby providing good back gas protection during welding. Preferably, the protective cover 70 is in a rectangular parallelepiped shape, ensuring good containment of components and protective gas.

[0038] The gas outlet channel 80 is opened on the upper surface of the first lifting mechanism 50 and is connected to the protective cover 70; by opening the gas outlet channel 80 on the upper surface of the first lifting mechanism 50, a good protective gas circulation effect can be achieved, thereby achieving the effect of accurately acting on the back of the welding product, and further achieving a good back gas protection effect.

[0039] The product is transported to a first preset position by the loading mechanism 20 and the feeding mechanism 30, respectively, and adjusted to a second preset position by the first lifting mechanism 50 and the second lifting mechanism 60, respectively, so that the pre-weld bead of the product is directly above the gas outlet 80. First, the position of the product to be welded is adjusted along the feed direction and along the horizontal direction and perpendicular to the feed direction by the multiple loading mechanisms 20 and the multiple feeding mechanisms 30, respectively, to directly above the gas outlet 80 of the first lifting mechanism 50, and then raised to the preset position by the multiple second lifting mechanisms 60. This ensures that the products to be welded are on the same horizontal plane and do not shift horizontally, thereby ensuring the subsequent welding accuracy.

[0040] From the above description, it can be seen that this application achieves the following technical effects:

[0041] In the embodiment of the present application, a mechanical clamping welding protection method is adopted, and the product is transported to the first preset position by the two loading mechanisms 20 and the two feeding mechanisms 30 respectively, and the product is adjusted to the second preset position by the first lifting mechanism 50 and the two second lifting mechanisms 60 respectively, so that the pre-weld position of the product is located directly above the air outlet channel 80, thereby achieving the purpose of adjusting the product to the required welding position, thereby realizing the technical effect of automatic welding protection, and further solving the current back protection method, which generally uses a homemade simple protective cover 70, and is protected by the back side by auxiliary personnel lifting, aligning and following the arc movement. There are the following disadvantages: auxiliary personnel are required, resulting in labor waste, and the auxiliary personnel need to have certain welding experience and cooperate with the welding operator, resulting in low efficiency technical problems.

[0042] Furthermore, the base 10 includes: a plurality of first-shaped steels 101 and a plurality of second-shaped steels 102. The plurality of first-shaped steels 101 are respectively arranged between the plurality of second-shaped steels 102, forming a T-shaped hollow base 10 located on the same horizontal plane. It is understood that by staggering the plurality of first-shaped steels 101 and second-shaped steels 102 in parallel and / or perpendicularly, a base 10 with a stable support structure can be formed, thereby facilitating the assembly of other components. At the same time, the T-shaped hollow structure can ensure good structural strength while also reducing weight and production costs.

[0043] like Figure 5-8 As shown, the feeding mechanism 20 includes: a shell 201, the shell 201 is hollow, a plurality of support rods 202 are arranged in the shell 201, a first driving component 203 is provided on the support rod 202 along the feeding direction, a first connecting plate 204 is provided at the output end of the first driving component 203, L-shaped connecting blocks 205 are respectively provided on both sides of the first connecting plate 204, the tops of the two L-shaped connecting blocks 205 are connected by a horizontally arranged mounting plate 206, the mounting plate 206 is located above the shell 201, and the bottoms of the two L-shaped connecting blocks 205 are respectively provided with slide rail assemblies 207, and the slide rail assemblies 207 are connected to the upper surface of the support rod 202;

[0044] The first drive component 203 provides driving force to drive the mounting plate 206 to reciprocate along the feed direction, and the mounting plate 206 drives the product feeding. It is understood that by disposing the first drive component 203 horizontally along the feed direction within the housing 201, a good horizontal drive effect can be achieved. The first drive component 203 can be a servo motor or a stepper motor combined with a lead screw, which is not limited in this application. Preferably, the slide rail assembly 207 can be in the form of a slider and a slide rail.

[0045] Furthermore, the feed mechanism 30 includes: two oppositely arranged fixed plates 301 connected to the upper surface of the mounting plate 206, two rotating shafts 302 are respectively provided between the two fixed plates 301 and near the top side, and two rotating wheels 303 are respectively provided on the two rotating shafts 302. A second driving component 304 connected to one of the fixed plates 301 is provided on one side of the rotating shaft 302, and the output ends of the two rotating wheels 303 are located on the same horizontal plane as the contact surface of the product. It can be understood that by using the second driving component 304 to provide a driving force to drive the rotating shaft 302 to rotate, thereby driving the rotating wheel 303 to rotate, and then driving the product to be welded to the specified position, ultimately achieving the effect of precise welding. By adopting this structure, the effect of position adjustment perpendicular to the feed direction can be achieved, thereby facilitating the adjustment of the welding position, thereby avoiding the tedious manual adjustment of the position. Among them, the second driving component 304 includes but is not limited to: a servo motor or a stepper motor. Of course, it is easy to think of that when using the corresponding motor-matched components, such as a motor with a reducer, etc., the easy-to-think and conventional mechanical structure will not be repeated in this application.

[0046] Furthermore, there are multiple feeding mechanisms 30, and the multiple feeding mechanisms 30 are arranged in an array on the mounting plate 206 in sequence, which can achieve good product movement and feeding effects.

[0047] Preferably, the feeding mechanisms 30 arranged relative to the first lifting mechanism 50 have opposite feeding directions. By providing two different feeding directions in the horizontal direction, a good forward and backward movement effect can be achieved, thereby achieving a convenient position adjustment effect. In this application, the forward and backward direction is the horizontal direction and perpendicular to the feeding direction.

[0048] Furthermore, the first lifting mechanism 50 includes a base plate 501 connected to the upper surface of the extension plate 40, two first support plates 502 vertically disposed on the base plate 501, the two first support plates 502 being arranged opposite each other perpendicular to the feed direction, a second connecting plate 503 disposed on top of the two first support plates 502, and two first lifting assemblies 504 being arranged opposite each other along the feed direction on the second connecting plates 503, the height of the first lifting assemblies 504 being higher than the height of the feed mechanism 30. It will be appreciated that the relative arrangement of the two first lifting assemblies 504 can achieve a good lifting effect, thereby achieving the effect of moving the product up and down, and thus achieving the effect of position adjustment; at the same time, it can also achieve the effect of cooperating with other components.

[0049] Furthermore, the first lifting assembly 504 includes: first linear bearings 505 arranged on both sides of the second connecting plate 503 along the feed direction, the two first linear bearings 505 are respectively located on the outside of the two first support plates 502, two first guide pillars 507 are respectively vertically arranged on the two first linear bearings 505, and a first workbench 506 is horizontally arranged on the top of the two first guide pillars 507. A third driving component 508 is provided at the bottom of the second connecting plate 503, and the output end of the third driving component 508 is connected to the center of the first workbench 506 via a bearing 509. It can be understood that the upward driving force provided by the third driving component 508 drives the second connecting plate 503 to move upward, and the two first guide pillars 507 are respectively provided on both sides of the bottom of the second connecting plate 503, which can achieve the effect of smooth movement of the second connecting plate 503 and a good coordination effect. Among them, the third driving component 508 includes but is not limited to: a cylinder.

[0050] Preferably, a sliding component is provided at the bottom of the first lifting mechanism 50 along the feeding direction; by providing the sliding component on the first lifting mechanism 50, a good sliding effect can be achieved, thereby achieving a good mobile back gas protection effect.

[0051] Furthermore, the second lifting mechanism 60 includes: two second support plates 601 connected to the upper surface of the extension plate 40, the two second support plates 601 are arranged opposite to each other perpendicular to the feeding direction, a third connecting plate 602 is provided on the top of the two second support plates 601, and second linear bearings 603 are provided on both sides of the third connecting plate 602 along the feeding direction, the two second linear bearings 603 are respectively located on the outside of the two second support plates 601, and two second guide columns 604 are vertically arranged on the two second linear bearings 603, and a second workbench 605 is horizontally arranged on the top of the two second guide columns 604, and a fourth driving component 606 is provided at the bottom of the third connecting plate 602, and the output end of the fourth driving component 606 is connected to the center of the second workbench 605 through a second bearing 607. It is understood that by symmetrically disposing a plurality of second lifting mechanisms 60 on the upper surface of the extension plate 40 relative to the first lifting mechanism 50, it is possible to achieve the effect of synchronously rising or falling in coordination with the first lifting mechanism 50, thereby achieving the effect of adjusting the position of the product to be welded; at the same time, by raising the height of the product, it can be separated from the feed mechanism 30, thereby preventing the welding effect of the product from being affected by improper operation of the feed mechanism 30. Of course, the product and the top of the feed mechanism 30 can be in contact, thereby achieving a good support effect. Furthermore, the top of the third connecting plate 602 is provided with a plurality of soft protrusions, which can achieve the effect of increasing frictional resistance. It is easy to imagine that the size of the third connecting plate 602 can be selected according to actual usage requirements.

[0052] Preferably, the initial height of the second lifting mechanism 60 is lower than the top height of the feeding mechanism 30 , which can avoid interference and ensure a good moving effect.

[0053] Preferably, a sliding assembly is provided at the bottom of the second lifting mechanism 60; this provides excellent sliding adjustment. By providing the sliding assembly, the desired spacing can be adjusted according to various usage scenarios, thereby adapting to diverse usage requirements. The sliding assembly can be in the form of a slide groove and a slider, enabling excellent position adjustment. When sliding to a preset position, the position is limited and fixed by a stop block.

A gas outlet pipe 703 corresponding to the position of the gas outlet channel 80 is provided in the hollow accommodating chamber, and one end of the gas outlet pipe 703 is connected to the gas inlet 704. It can be understood that by respectively providing the first protective shell 701 and the second protective shell 702 at the bottom of the two second connecting plates 503, the position of the two first lifting assemblies 504 can be adjusted to enclose and form a hollow chamber, thereby achieving a good component or gas accommodating effect, thereby providing a guarantee for the subsequent directional flow of gas. At the same time, it can also achieve a staggered effect, thereby facilitating the installation or replacement of other components. For example, to improve the sealing of the edge junction of the protective shell, the provision of a sealing component can achieve an improved airtightness. The material of the sealing component includes but is not limited to: O-ring or other forms of wear-resistant gasket.

[0055] Preferably, the protective cover 70 can be a one-piece structure with an open top. This structure improves gas sealing performance, thereby reducing the number of components to be installed and used. By detachably positioning the protective cover 70 at the bottom of the second connecting plate 503, it facilitates the removal and assembly of other components. Furthermore, a drive cylinder is provided at the center of the bottom of the protective cover, allowing the use of a single drive cylinder to avoid the need for multiple cylinders.

It can be understood that by respectively providing a clamping mechanism 90 on the side of several second lifting mechanisms 60 away from the feeding mechanism 30, the effect of clamping and limiting the product can be achieved, thereby ensuring that the product is in a good stable state, thereby avoiding abnormal movement. Among them, the bending plate 901 can be L-shaped, and can achieve a good clamping effect on both sides by installing components thereon and applying a downward force. Preferably, the limiting part can be a limiting cylinder.

[0057] Furthermore, the clamping mechanism can be a combination of bolts and nuts, which can achieve an effect of easy operation.

[0058] Furthermore, a vertical support 100 is provided on the base 10, adjacent to the first lifting mechanism 50, and a manipulator 110 is provided on the vertical support 100. It will be appreciated that the provision of the vertical support 100 on one side of the base 10 enables effective component installation and fixation; at the same time, the provision of the manipulator 110 on the vertical support 100 enables automated welding. Of course, the model and specifications of the manipulator 110 can be changed based on actual usage requirements and are not limited in this application.

[0059] Furthermore, a plurality of limit sensors can be provided and controlled in coordination with a plurality of driving components; thus, a precise position control effect can be achieved.
