[0002] A hopper is a common type of metal workpiece. During production, the various plates that make up the hopper need to be welded together.

[0003] like Figure 1 As shown, a hopper is provided. The hopper mainly includes two side plates 11 and a bent plate 12 disposed between the two side plates 11. The bent plate 12 is formed by multiple bending. The bent plate 12 includes a top plate 121, a bottom plate 122 and a multi-stage bending plate located between the top plate 121 and the bottom plate 122. The two ends of the bent plate 12 are respectively welded to the two side plates 11 to form a hopper with one end open.

[0004] In the existing technology, when welding the hopper, the bending plate 12 and the two side plates 11 need to be connected together by spot welding first, and then the connection between the bending plate 12 and the side plates 11 needs to be fully welded. However, when performing full welding, the hopper needs to be moved and flipped frequently, which makes the welding efficiency low and time-consuming and labor-intensive. Utility Model Content

Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0035] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0036] Example: An automated welding hopper clamp, see attached document. Figure 2 - Appendix Figure 8 The device includes a frame 2 and a clamping mechanism 4. The frame 2 is supported on the ground. The clamping mechanism 4 is used to clamp the hopper that has undergone spot welding. The clamping mechanism 4 can rotate on the frame 2 about at least two mutually perpendicular axes. The clamping mechanism 4 includes a support frame 41, sliding plates 42, and pressure heads 44. The support frame 41 is connected to the frame 2. Two sliding plates 42 are provided. The two sliding plates 42 slide on the support frame 41 along the length of the support frame 41 to achieve mutual approach and mutual distance. Two pressure heads 44 are provided and are respectively located on the two sides of the two sliding plates 42 that are far apart from each other. The two sliding plates 42 can be inserted into the hopper and the two pressure heads 44 are respectively supported and tightened on the inner sides of the two side plates 11 of the hopper by sliding far apart from each other.

[0037] By sliding the two sliding plates 42 in a direction away from each other, the pressure head 44 can be pressed tightly against the inner side of the two side plates 11 of the hopper, thereby clamping the hopper. Then, by rotating the clamping mechanism 4 on the frame 2, the hopper can be fully welded by manual or robotic arms, which saves time and effort and improves welding efficiency.

[0038] Specifically, the support frame 41 includes a guide plate 411 and an end plate 412. There are two guide plates 411, which are parallel to each other and are both rectangular plates. There are two end plates 412, which are respectively located at both ends of the guide plates 411. The end plates 412 are fixedly connected to the two guide plates 411.

[0039] Specifically, a rotating rod 413 is provided between the two guide plates 411, with its two ends rotatably connected to the two end plates 412 respectively. The length direction of the rotating rod 413 is along the length direction of the guide plate 411. Two sliders 414 are provided between the two guide plates 411. The two sliders 414 slide between the two guide plates 411 along the length direction of the rotating rod 413. The rotating rod 413 passes through the two sliders 414 along its own length direction. Two external threads with opposite helical directions are provided on the outside of the rotating rod 413, and the two external threads are respectively threaded with the two sliders 414. Two sliding plates 42 are respectively connected to the two sliders 414.

[0040] By rotating the rotating rod 413, the two sliders 414 can slide between the two guide plates 411 along the length of the rotating rod 413, thereby enabling the two sliders 414 to move closer to each other and further away from each other, which in turn enables the two sliding plates 42 to move closer to each other and further away from each other.

[0041] Specifically, a positioning surface parallel to the guide plate 411 is provided on one side of the sliding plate 42, and the top plate 121 of the hopper, which is supported on the two pressure heads 44, abuts against the positioning surface on the side near the opening of the hopper.

[0042] Specifically, two sliding rods 45 are provided on the sliding plate 42. The length direction of the sliding rods 45 is perpendicular to the sliding direction of the sliding plate 42 and parallel to the guide plate 411. The two sliding rods 45 are located on the side of the sliding plate 42 where the pressure head 44 is located, and the two sliding rods 45 can respectively abut against the sides of the top plate 121 and bottom plate 122 of the hopper that are close to each other. By providing the sliding rods 45, the top plate 121 and bottom plate 122 of the hopper can be supported tightly, preventing the hopper from displacing along the length direction of the sliding rods 45 when the clamping mechanism 4 rotates.

[0043] Specifically, a telescopic rod 441 is provided on the side of the pressure head 44 near the sliding plate 42. The length direction of the telescopic rod 441 is along the length direction of the sliding plate 42. The telescopic rod 441 slides on the sliding plate 42 along its own length direction. An elastic element 422 is provided on the sliding plate 42. The pressure head 44 and the sliding rod 45 are connected by a connecting rod 46. The two ends of the connecting rod 46 are respectively hinged to the pressure head 44 and the sliding rod 45. When the pressure head 44 presses against the side plate 11 and compresses the elastic element 422, the two connecting rods 46 respectively push the two sliding rods 45 to slide in a direction away from each other so as to abut against the top plate 121 and the bottom plate 122 of the hopper respectively.

[0044] Specifically, a guide tube 421 is provided on the side of the two sliding plates 42 that are close to each other. The telescopic rod 441 is inserted into the guide tube 421 on the corresponding sliding plate 42 to slide within the guide tube 421. The end of the guide tube 421 away from the sliding plate 42 is closed. The elastic element 422 is a spring, and the two ends of the spring are fixedly connected to the guide tube 421 and the telescopic rod 441 respectively. When the elastic element 422 is in its normal state, the distance between the two ends of the two sliding rods 45 that are far from each other is less than the distance between the top plate 121 and the bottom plate 122.

[0045] Specifically, a fixed frame 43 is fixedly connected to the support frame 41, and a cylinder 431 is fixedly connected to the fixed frame 43. The piston rod of the cylinder 431 slides in a direction parallel to the sliding rod 45 and can press against the top plate 121 on the side away from the bottom plate 122.

[0046] The cylinder 431 helps to fix the hopper with the help of the pressure head 44 and the sliding rod 45.

[0047] Specifically, a robotic arm 3 is rotatably connected to the frame 2, and the axis of rotation of the robotic arm 3 on the frame 2 is horizontal; a support frame 41 is rotatably connected to the robotic arm 3, and the axis of rotation of the support frame 41 on the robotic arm 3 is horizontal and perpendicular to the axis of rotation of the robotic arm 3 on the frame 2.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
