[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0047] like Figures 1 to 5 As shown, the welding device 100 of this utility model embodiment includes a base 1, a mounting plate 2, a lifting assembly 3, a clamping assembly 4, a pressing assembly 5, and a welding robot.

[0048] Mounting plate 2 is vertically mounted on base 1 and is used to place workpiece 200.

[0049] The lifting assembly 3 is located between the base 1 and the mounting plate 2. The lifting assembly 3 is used to adjust the distance between the mounting plate 2 and the base 1.

[0050] Multiple clamping assemblies 4 are arranged in pairs on both sides of the mounting plate 2. The clamping assembly 4 includes a jaw 41 for clamping the workpiece 200.

[0051] Multiple clamping components 5 are arranged at intervals. Each clamping component 5 includes a clamping claw 51, which is used to clamp the workpiece 200 onto the mounting plate 2. The clamping claw 41 and the clamping claw 51 are arranged alternately.

[0052] The welding robot includes a welding torch 6.

[0053] For example, for ease of description, the technical solution of this application will be described below with the first direction as the left-right direction, the second direction as the front-back direction, and the third direction as the up-down direction. The left-right, front-back, and up-down directions are as follows: Figure 1 As shown.

[0054] The mounting plate 2 can be raised and lowered on the base 1 and its height can be adjusted by the lifting component 3.

[0055] Multiple clamping components 4 are arranged in pairs on the left and right sides of the mounting plate 2, that is, two clamping components 4 in each pair are respectively arranged on the left and right sides of the mounting plate 2. The jaws 41 are used to firmly clamp the workpiece 200 to prevent it from shifting or vibrating during the welding process, thereby avoiding displacement of the workpiece 200 in the left and right directions. The number of clamping components 4 is 2 to 10, etc.

[0056] Multiple clamping components 5 are arranged at intervals around the mounting plate 2. For example, multiple clamping components 5 are arranged on the left and right sides or the front and back sides of the mounting plate 2, or clamping components 5 are arranged on both the left and right sides and the front and back sides of the mounting plate 2.

[0057] The clamping claw 51 is used to press the workpiece 200 onto the surface of the mounting plate 2, thereby preventing the workpiece 200 from moving in the vertical direction.

[0058] The alternating arrangement of the gripper 41 and the pressure gripper 51 forms a layout that can both clamp and press, thereby improving the stability of the workpiece 200.

[0059] The welding torch 6 performs precise welding operations according to preset paths and parameters through programming control.

[0060] In related technologies, when manually welding workpieces of 200, the welding quality is often unstable and the product consistency is poor due to the influence of human factors, such as the operator's experience, skill level and working conditions.

[0061] The welding device 100 of this utility model integrates a base 1, a mounting plate 2, a lifting component 3, a clamping component 4, a pressing component 5, and a welding robot equipped with a welding gun 6 into one unit, realizing the fully automated operation of the workpiece 200 from positioning, clamping, pressing to welding.

[0062] First, the lifting assembly 3 can adjust the height of the mounting plate 2, ensuring that each workpiece 200 can be processed in the optimal position. Second, the combined use of the clamping assembly 4 and the pressing assembly 5 not only firmly fixes the position of the workpiece 200 but also effectively prevents any displacement or deformation of the workpiece 200 during the welding process, thereby ensuring welding accuracy. Furthermore, the application of the welding robot greatly improves the quality and efficiency of welding. It can perform highly precise welding tasks according to preset program parameters, reducing human error and improving product consistency and stability.

[0063] Therefore, this invention not only solves the problems of traditional manual welding, but also improves production efficiency and product quality.

[0064] In some embodiments, such as Figure 2 and Figure 3 As shown, the clamping assembly 4 includes two clamping assemblies 4, which are arranged opposite to each other on both sides of the mounting plate 2 in the first direction;

[0065] The lifting assembly 3 includes two components, which are arranged opposite to each other on both sides of the mounting plate 2 in a second direction, which is perpendicular to the first direction.

[0066] The clamping assembly 5 comprises four, which are arranged in pairs on both sides of the mounting plate 2 in the first direction.

[0067] For example, the clamping assembly 4 includes two clamping assemblies 4, which are arranged opposite each other on the left and right sides of the mounting plate 2 to achieve bidirectional clamping of the workpiece 200 and ensure the stable positioning of the workpiece 200 in the left and right directions. In addition, the pressing assembly 5 includes four pressing assemblies 5, with two pressing assemblies 5 located on the left side of the mounting plate 2 and the other two pressing assemblies 5 located on the right side of the mounting plate 2. On either the left or right side of the mounting plate 2, the clamping assembly 4 is located between two pressing assemblies 5.

[0068] The lifting assembly 3 includes two components, which are arranged opposite each other on both sides of the mounting plate 2 in the front-rear direction.

[0069] The welding device 100 of this utility model arranges the clamping component 4 and the pressing component 5 on the left and right sides of the mounting plate 2, and arranges the lifting component 3 on the front and rear sides of the mounting plate 2. This arrangement not only ensures that the mounting plate 2 can be adjusted in a stable and accurate manner, but also makes the whole structure more compact and efficient by making reasonable use of space.

[0070] In some embodiments, such as Figure 3 As shown, the lifting assembly 3 includes a lifting cylinder 31, a lifting rod, and a support plate 32.

[0071] One end of the lifting rod is connected to the lifting cylinder 31. The lifting rod can move along a third direction, which is perpendicular to both the first and second directions.

[0072] The other end of the lifting rod is connected to the support plate 32, and the top surface of the support plate 32 is in contact with the bottom surface of the mounting plate 2.

[0073] For example, the lifting cylinder 31 serves as a power source to drive the entire lifting process. The lower end of the lifting rod is connected to the lifting cylinder 31, and the lifting rod can move in the vertical direction. The top end of the lifting rod is connected to the bottom of the support plate 32, and the top surface of the support plate 32 is in close contact with the bottom surface of the mounting plate 2.

[0074] In some embodiments, such as Figure 4 As shown, the clamping assembly 4 includes a clamping cylinder 42, a first connecting rod 43, and a swing rod 44.

[0075] The clamping cylinder 42 is located between the mounting plate 2 and the base 1. The output shaft of the clamping cylinder 42 extends along the first direction, and the output shaft of the clamping cylinder 42 can move relative to the clamping cylinder 42 along the first direction.

[0076] The first connecting rod 43 and the output shaft of the clamping cylinder 42 are arranged in parallel in the third direction. The first connecting rod 43 is located near the mounting plate 2 relative to the output shaft of the clamping cylinder 42, and one end of the first connecting rod 43 is rotatably connected to the clamping cylinder 42.

[0077] The swing rod 44 extends in a third direction. The bottom of the swing rod 44 is rotatably connected to the output shaft of the clamping cylinder 42. The top of the swing rod 44 is provided with a gripper 41. The other end of the first connecting rod 43 is rotatably connected to the swing rod 44. The swing rod 44 can swing relative to the first connecting rod 43 in a first direction.

[0078] For example, the output shaft of the clamping cylinder 42 extends in the left-right direction, and the output shaft of the clamping cylinder 42 can move in the left-right direction;

[0079] The first connecting rod 43 and the output shaft of the clamping cylinder 42 are arranged parallel in the vertical direction. The output shaft of the clamping cylinder 42 is located below the first connecting rod 43. One end of the first connecting rod 43 is hinged to the housing of the clamping cylinder 42, and the other end of the first connecting rod 43 is hinged to the swing rod 44. The output shaft of the clamping cylinder 42 is hinged to the swing rod 44. The swing rod 44 extends in the vertical direction, and the top of the swing rod 44 is provided with a jaw 41 for clamping the workpiece 200. When the clamping assembly 4 is working, the output shaft of the clamping cylinder 42 can move in the left and right direction, thereby driving the swing rod 44 to swing relative to the first connecting rod 43 in the left and right direction, and in turn driving the jaw 41 to swing in the left and right direction, thereby realizing the clamping and release of the workpiece 200.

[0080] In some embodiments, such as Figure 1 As shown, the gripper 41 is provided with multiple weight reduction holes 411.

[0081] Weight reduction holes 411 are evenly distributed on the main structure of the gripper 41. By reducing the overall weight of the gripper 41, its movement flexibility and response speed are improved. At the same time, this design can also effectively reduce the inertial influence caused by the excessive weight of the gripper 41 during operation of the clamping assembly 4, thereby improving the accuracy and stability of the clamping operation.

[0082] In some embodiments, such as Figure 5 As shown, the clamping assembly 5 includes a clamping cylinder 52, a second connecting rod 53, and a clamping claw 51. The output shaft of the clamping cylinder 52 extends in the third direction and can move in the third direction.

[0083] The second connecting rod 53 is arranged in parallel with the output shaft of the clamping cylinder 52, and one end of the second connecting rod 53 is rotatably connected to the clamping cylinder 52.

[0084] The pressure claw 51 is rotatably connected to the output shaft of the clamping cylinder 52 and the second connecting rod 53, and the pressure claw 51 can swing relative to the second connecting rod 53 in the third direction.

[0085] For example, the output shaft of the clamping cylinder 52 extends in the vertical direction and can move in the vertical direction; the output shaft of the clamping cylinder 52 is hinged to the gripper 41.

[0086] The second connecting rod 53 extends vertically and is arranged parallel to the output shaft of the clamping cylinder 52.

[0087] The bottom of the second connecting rod 53 is hinged to the housing of the clamping cylinder 52, and the top of the second connecting rod 53 is hinged to the clamping claw 51.

[0088] When the clamping cylinder 52 is working, the output shaft of the clamping cylinder 52 moves in the up and down direction, thereby driving the clamping claw 51 to swing up and down relative to the top of the second connecting rod 53, thereby clamping or releasing the workpiece 200.

[0089] In some embodiments, such as Figure 1 As shown, the end of the pressure claw 51 that contacts the workpiece 200 has a chamfer 511.

[0090] The chamfer 511 is designed to optimize the movement path of the welding torch 6 during the welding process. When the welding torch 6 welds the workpiece 200 near the pressure claw 51, the chamfer 511 can effectively prevent the pressure claw 51 from interfering with the movement of the welding torch 6, ensuring that the welding torch 6 can operate smoothly along the predetermined trajectory, thereby improving the accuracy and efficiency of welding. Through this ingenious design, not only is the risk of collision between the welding torch 6 and the pressure claw 51 reduced, but the visibility and accessibility of the welding area are also improved, making the welding process smoother and easier to control.

[0091] In some embodiments, such as Figure 1 As shown, the clamping assembly 5 includes a cylinder bracket 54, which consists of a base plate 541, two side plates 542, and a back plate 543. The two side plates 542 are arranged opposite each other in a second direction. The back plate 543 is located between the two side plates 542, and in a first direction, the back plate 543 is located at one end of the base plate 541 adjacent to the lifting assembly 3.

[0092] The base plate 541, two side plates 542 and back plate 543 define the mounting cavity, and the clamping cylinder 52 is located in the mounting cavity.

[0093] For example, the two side plates 542 are arranged opposite each other in the front-to-back direction, and the back plate 543 is located between the two side plates 542. In the left-to-right direction, the back plate 543 is located at the end of the base plate 541 near the lifting assembly 3. This structural design allows the base plate 541, the two side plates 542 and the back plate 543 to jointly define a mounting cavity, and the clamping cylinder 52 is placed in the mounting cavity.

[0094] The welding device 100 of this utility model embodiment, by setting a cylinder bracket 54, can not only effectively fix and protect the clamping cylinder 52, avoiding it from being affected by external interference or damage during operation, but also improve the compactness and stability of the overall structure through a reasonable spatial layout.

[0095] Optionally, the side panel 542 is triangular.

[0096] In some embodiments, such as Figure 1 As shown, the welding device 100 includes a controller, which includes a lifting control valve 7, a clamping control valve 8, and a pressing control valve 9. The lifting control valve 7 is electrically connected to the lifting assembly 3, the clamping control valve 8 is electrically connected to the clamping assembly 4, and the pressing control valve 9 is electrically connected to the pressing assembly 5.

[0097] For example, the lifting control valve 7 is electrically connected to the lifting cylinder 31 and is used to precisely control the action of the lifting cylinder 31 to achieve flexible adjustment of the height of the mounting plate 2;

[0098] The clamping control valve 8 is electrically connected to the clamping cylinder 42. By controlling the movement of the output shaft of the clamping cylinder 42, the clamping jaw 41 is driven to complete the clamping or releasing operation of the workpiece 200.

[0099] The clamping control valve 9 is electrically connected to the clamping cylinder 52 and is used to adjust the clamping force of the clamping claw 51 on the workpiece 200 to ensure that the workpiece 200 remains stable during the welding process.

[0100] The welding device 100 of this utility model can directly control the corresponding components using a controller, or can also be manually intervened when needed, so as to flexibly adjust various parameters according to actual processing requirements, thereby significantly improving the automation level and operating efficiency of the welding device 100, while ensuring the accuracy and reliability of the entire welding process.

[0101] In some embodiments, such as Figure 2 As shown, the mounting plate 2 has a notch 21 at one end in the second direction.

[0102] The front or rear end of the mounting plate 2 is designed with a notch 21 structure. Its main purpose is to facilitate the removal of the workpiece 200 during operation. The notch 21 design can effectively prevent the edge of the mounting plate 2 from interfering with the operator's hand or the mechanical claw that moves the workpiece 200, thereby improving the convenience and safety of operation.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
