Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a plate welding device. Background Art

[0002] Automobile hinges are often opened and closed, so they are prone to rust and fall off after a long time. Welding a reinforcement plate on the inner wall of the automobile hinge will prevent the hinge from separating from the side plate when the hinge is turned upside down, because there is an additional reinforcement plate between the hinge and the side plate, which can extend the service life of the hinge. When the hinge is welded to the reinforcement plate, there is a gap between the two, which reduces the welding strength.

[0003] Chinese patent announcement number CN218426469U discloses a plate welding device. Through the design of a first threaded screw and a clamping plate, a first drive motor is used to drive the first threaded screw to rotate, and the first threaded screw drives the two clamping plates to approach each other, thereby fixing the plate from both sides to prevent the plate from shifting during the welding process and affecting the welding effect. The adjustment of the spacing between the clamping plates enables the device to fix plates of various sizes, thereby significantly improving the applicability of the device.

[0004] However, the above patent has the following shortcomings:

[0005] The welding device only limits the position of the plate in the horizontal direction, so the plate is prone to warping when butt-jointed, resulting in a height difference between the two plates when butt-jointed, thereby reducing the welding effect. Utility Model Content

[0006] The utility model aims to solve the problems existing in the background technology and to provide a plate welding device which can eliminate the height difference of the plates in the vertical direction during welding and improve the welding effect.

[0008] Preferably, the clamping mechanism includes a moving mechanism a arranged on the workbench and two symmetrically arranged clamping plates.

[0010] Preferably, it also includes an abutment bolt with a thread arranged in the workbench, the end of the abutment bolt is located in the fixing groove and the abutment bolt abuts against the reinforcing plate.

[0011] Preferably, the pressing mechanism comprises a pressing frame arranged on the workbench, a cylinder arranged on the pressing frame, and a pressing block arranged at the output end of the cylinder.

[0012] Preferably, the welding mechanism includes a moving mechanism b arranged on a workbench and a welding tool arranged on the moving mechanism b.

[0013] Preferably, the moving mechanism b includes a transverse moving frame arranged on the workbench, a rotating motor a arranged on the transverse moving frame, a screw a rotatably arranged on the transverse moving frame and driven and connected by the rotating motor a, a vertical moving frame slidably arranged in the transverse moving frame, a rotating motor b arranged on the vertical moving frame, a screw b rotatably arranged on the vertical moving frame and driven and connected by the rotating motor b, a longitudinal moving frame slidably arranged in the vertical moving frame, a rotating motor c arranged on the longitudinal moving frame, and a screw c rotatably arranged on the longitudinal moving frame and driven and connected by the rotating motor c, and the welding tool is slidably arranged on the longitudinal moving frame and threadedly connected to the screw c.

[0014] Compared with the prior art, the utility model has the following beneficial technical effects:

DETAILED DESCRIPTION

[0023] Embodiment 1

[0024] like Figure 1-Figure 5 As shown, a plate welding device proposed in this embodiment includes a workbench 1, a clamping mechanism 2, a pressing mechanism 3 and a welding mechanism 4. The workbench 1 has a groove 101 for placing the hinge 100 and a fixing groove 102 for placing the reinforcing plate 200. The arrangement of the groove 101 facilitates the welding surface of the hinge 100 to be tightly abutted against the reinforcing plate 200 to avoid a gap between the welding surface of the hinge 100 and the reinforcing plate 200. The reinforcing plate 200 is set as an L-shaped plate, and the fixing groove 102 can fix the position of the reinforcing plate 200.

[0025] The clamping mechanism 2 is arranged on the workbench 1, and is used to clamp the hinge 100. After the hinge 100 is placed on the workbench 1, the clamping mechanism 2 is activated to fix and clamp the hinge 100. The pressing mechanism 3 is arranged on the workbench 1, and is used to press the hinge 100 and the reinforcing plate 200. After the hinge 100 is placed on the reinforcing plate 200, the pressing mechanism 3 is activated to press the hinge 100 against the reinforcing plate 200 to avoid a gap between the hinge 100 and the reinforcing plate 200. The welding mechanism 4 is arranged on the workbench 1, and is used to perform welding.

[0026] When in use, the reinforcing plate 200 is placed in the fixing groove 102, and then the hinge 100 is placed at the position on the reinforcing plate 200 where welding is required. The clamping mechanism 2 is started to clamp the hinge 100, and the position of the hinge 100 is fixed to prevent the hinge 100 from moving during welding. The pressing mechanism 3 is started to tightly contact the welding surface of the hinge 100 against the reinforcing plate 200 to avoid a gap between the welding surface of the hinge 100 and the reinforcing plate 200. The welding mechanism 4 is started to weld. This allows the hinge 100 and the reinforcing plate 200 to have no height difference in the vertical direction during welding, thereby improving the welding effect.

[0027] Embodiment 2

[0028] like Figure 2 As shown, the plate welding device proposed in this embodiment, compared with the first embodiment, in this embodiment, the clamping mechanism 2 includes a moving mechanism a201 and two symmetrically arranged clamping plates 202 arranged on the workbench 1. The moving mechanism a201 is started to drive the clamping plates 202 to move.

[0029] The moving mechanism a201 includes a driving motor 211 disposed on the workbench 1 and a bidirectional screw 212 rotatably disposed on the workbench 1 and driven and connected by the driving motor 211. The workbench 1 has a sliding groove 103, the bidirectional screw 212 is located in the sliding groove 103, the clamping plate 202 is slidably disposed in the sliding groove 103, and the two clamping plates 202 are respectively threadedly connected to both ends of the bidirectional screw 212. The driving motor 211 is started to drive the bidirectional screw 212 to rotate, driving the two clamping plates 202 to slide relative to each other in the sliding groove 103, clamping and fixing the hinge 100 in the middle position, and ensuring the relative position relationship between the hinge 100 and the reinforcing plate 200.

[0030] The plate welding device further includes an abutment bolt 5 threadedly disposed in the workbench 1, the end of which is located in the fixing groove 102 and abutted against the reinforcing plate 200. A gap is left in the fixing groove 102 to facilitate placement of the reinforcing plate 200. After the reinforcing plate 200 is placed in the fixing groove 102, the abutment bolt 5 is rotated to abut the reinforcing plate 200 against the inner wall of the fixing groove 102, thereby limiting the position of the reinforcing plate 200.

[0031] The pressing mechanism 3 comprises a pressing frame 301 arranged on the workbench 1, a cylinder 302 arranged on the pressing frame 301, and a pressing block 303 arranged at the output end of the cylinder 302. The cylinder 302 is started to drive the pressing block 303 to move.

[0032] This embodiment describes in detail the specific structures of the clamping mechanism 2 and the pressing mechanism 3, and describes the connection relationship of the abutment bolt 5. After the reinforcing plate 200 is inserted into the fixing groove 102, the abutment bolt 5 is rotated to fix the reinforcing plate 200. After the fixing is completed, the hinge 100 is placed on the reinforcing plate 200, and the driving motor 211 is started to drive the bidirectional screw 212 to rotate, driving the two clamping plates 202 to move relative to each other to clamp the hinge 100 in the center position on the workbench 1. After the hinge 100 is clamped, the cylinder 302 is started to drive the pressing block 303 to move downward, and the welding surface of the hinge 100 is tightly pressed on the reinforcing plate 200 to avoid a gap between the welding surface of the hinge 100 and the reinforcing plate 200.
