DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1-Figure 4 , which is the first embodiment of the present invention, and provides a metal sheet welding device, the metal sheet welding device includes an adjustment component 200, including a bearing plate 201a, a slide rail 201b, a fixed shaft 201c, a guide rail 201d, a guide shaft 201e, a stopper 201f, a rotating column 201g, a gear 201h, a rack 201i, a torsion spring 201j, a locking member 202 and a connecting member 203, the slide rail 201b is located on one side of the bearing plate 201a, one end of the fixed shaft 201c is fixed to the bearing plate 201a, and the guide rail 201d is arranged on the bearing plate On one side of 201a, one end of the guide shaft 201e is fixed to the supporting plate 201a, the stopper 201f is located in the guide rail 201d and contacts the guide shaft 201e, the rotating column 201g is rotatably connected in the fixed shaft 201c, the gear 201h is fixed to one end of the rotating column 201g, the rack 201i is located at the bottom of the gear 201h and meshes with the gear 201h, the torsion spring 201j is sleeved on the outside of the rotating column 201g, and one end is fixed to the inner wall of the fixed shaft 201c, the locking member 202 is located in the stopper 201f, and the connecting member 203 is arranged on the rotating column 201g.

[0035] There are two groups of adjustment components 200, which are used to support and position two metal plates at the same time. The slide rails 201b are slidably connected to the inside of the slide rails 201b, the guide rails 201d are arc-shaped, and the guide shafts 201e are slidably connected to the inside of the guide rails 201d.

[0036] If it is necessary to weld the two metal plates into a horizontal state, the stopper 201f is placed at the bottom inside the guide rail 201d.

[0037] When welding the metal plate, place the metal plate on top of the supporting plate 201a, and use the two supporting plates 201a to drive the two metal plates to move in the center so that the two metal plates are in contact at the positions where they need to be welded. When the supporting plate 201a moves, it drives the gear 201h to rotate on the rack 201i, and drives the rotating column 201g to rotate through the gear 201h. The rotating column 201g tightens the torsion spring 201j through the cooperation of the connecting piece 203, so that the torsion spring 201j is in an energized state.

[0038] When the supporting plate 201a stops moving and the two metal plates are in full contact, the stopper 201f is at the bottom of the guide rail 201d, and the guide shaft 201e can be blocked by the stopper 201f, so that the guide shaft 201e cannot rotate upward along the inner wall of the guide rail 201d, thereby making the two supporting plates 201a and the two metal plates in a horizontal state, and the two metal plates can be connected into a horizontal state.

[0039] When it is necessary to weld the two metal plates at other angles, it is only necessary to move the block 201f upward in the guide rail 201d and move it to the specified position. At this time, when the supporting plate 201a stops moving and the two metal plates are fully in contact, the fixed shaft 201c can be driven to rotate by the charged torsion spring 201j, and the supporting plate 201a can be driven to rotate upward by the fixed shaft 201c, so that the supporting plate 201a drives the guide shaft 201e to slide in the guide rail 201d, so that the metal plates can be tilted through the supporting plate 201a, and the two metal plates can be welded to other different angles, and the angle of the metal plates can be accurately fixed to ensure that the angle after welding meets the design requirements, reduce quality problems caused by angle deviation, and at the same time, there is no need to frequently change molds or perform manual support, which saves operation time and improves overall production efficiency.

[0040] The locking member 202 is provided to lock the stopper 201f at a specified position inside the guide rail 201d, thereby preventing the stopper 201f from being offset when squeezed by the guide shaft 201e, thereby causing the angle of the metal plate to deviate.

[0041] The connection piece 203 is used to connect the rotating column 201g and the torsion spring 201j. When the rotating column 201g initially rotates, the torsion spring 201j is driven to rotate through the connection piece 203 and the torsion spring 201j is tightened. If the supporting plate 201a does not rotate upward after stopping moving, the torsion spring 201j is not released. When the rotating column 201g rotates in the opposite direction, the tightened torsion spring 201j can be released to avoid the torsion spring 201j being damaged due to being in a tightened state for a long time.

[0042] When the supporting plate 201a stops moving, the angle of upward rotation released by the torsion force of the torsion spring 201j is not enough to completely release the elastic force of tightening the torsion spring 201j. When the rotating column 201g rotates in the reverse direction, the remaining part of the torsion spring 201j will be charged and released. When the charged energy of the torsion spring 201j is completely released and the rotating column 201g is still rotating in the reverse direction, the connecting member 203 will separate the rotating column 201g from the torsion spring 201j, so that the rotating column 201g rotates independently without driving the torsion spring 201j to be tightened, thereby avoiding the rotating column 201g from generating a reverse torsion force on the torsion spring 201j when it moves in the reverse direction. When the two supporting plates 201a move in the center and cause the rotating column 201g to rotate again, it will result in that when the rotating column 201g stops rotating, the torsion spring 201j cannot be tightened to a sufficient degree, thereby making the supporting plate 201a unable to rotate upward to the required angle.

[0043] Example 2

[0044] Reference Figure 5-Figure 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0045] Specifically, it also includes a clamping assembly 300, which is arranged on one side of the supporting plate 201a, including a fixed frame 301a, a movable block 301b, a pressure block 301c and a first spring 301d. One side of the fixed frame 301a is fixed to the supporting plate 201a, the movable block 301b is located in the fixed frame 301a, the pressure block 301c is inserted into the movable block 301b, and both ends of the first spring 301d are respectively fixed to the movable block 301b and the inner wall of the fixed frame 301a.

[0046] The number of clamping assemblies 300 corresponds to the number of adjusting assemblies 200. There are two groups of clamping assemblies 300 on a carrier plate 201a, which are respectively located on both sides of the carrier plate 201a. The two groups of clamping assemblies 300 can simultaneously press and fix both sides of the top metal plate of the carrier plate 201a, thereby preventing the metal plate from loosening during welding.

[0047] A through slot is provided on the movable block 301b, and the pressing block 301c is movably connected in the through slot. When the metal plate is placed on the top of the supporting plate 201a, a downward pulling force is applied to the movable block 301b through the first spring 301d, and the pressing block 301c is driven to move downward by the movable block 301b, so that the pressing block 301c can press the metal plate downward, and then the metal plate and the supporting plate 201a can be closely fitted, thereby preventing the metal plate from being displaced on the top of the supporting plate 201a, which may cause deviation during welding.

[0048] When the supporting plate 201a drives the metal plates to move and makes the two metal plates contact, the movement of the supporting plate 201a will make the connection between the two metal plates fit more tightly, thereby avoiding the formation of gaps at the connection between the two metal plates, which will lead to quality problems after welding.

[0049] When the welding is completed and the metal plate needs to be removed, the pressing block 301c is pulled to one side to separate the pressing block 301c from the metal plate, thereby releasing the fixation between the metal plate and the supporting plate 201a, and the welded metal plate can be removed.

[0050] Specifically, a support block 301e is fixed to one side of the pressing block 301c, a seventh spring 301f is fixed to one side of the supporting block 301e, and the other end of the seventh spring 301f is fixed to the movable block 301b.

[0051] The seventh spring 301f applies a pulling force to the support block 301e, so that the support block 301e can drive the pressing block 301c to move, so that the pressing block 301c can always be in a position fixed to the metal plate.

[0052] Specifically, the connecting member 203 includes a slider 203a, a block 203b and a second spring 203c. A sliding groove 201g-1 is provided on the rotating column 201g. The slider 203a slides in the sliding groove 201g-1. A movable groove 203a-1 is provided on the slider 203a. The block 203b is located in the movable groove 203a-1. The two ends of the second spring 203c are respectively fixed to the inner wall of the movable groove 203a-1 and the block 203b. A slot 201g-2 is provided on the rotating column 201g, and the block 203b is engaged with the slot 201g-2.

[0053] The slider 203a is fixed to the other end of the torsion spring 201j, one side of the clamping block 203b is inclined, the slider 203a and the slide groove 201g-1 are both T-shaped, and there are multiple clamping grooves 201g-2, which are evenly distributed in a ring shape in the rotating column 201g.

[0054] When the rotating column 201g rotates initially, it will drive the inner wall of the slot 201g-2 to squeeze the side of the block 203b, thereby driving the block 203b and the slider 203a to rotate at the same time, and tighten the torsion spring 201j during the rotation of the slider 203a.

[0055] If the energy of the torsion spring 201j is not fully released, when the rotating column 201g rotates in the reverse direction, the torsion force generated by the torsion spring 201j will drive the slider 203a to rotate synchronously with the rotating column 201g. When the energy of the torsion spring 201j is fully released, the rotating column 201g will drive the inner wall of the slot 201g-2 to squeeze the inclined surface of the block 203b, thereby pushing the block 203b to move and separating the block 203b from the slot 201g-2, thereby separating the rotating column 201g from the slider 203a, thereby preventing the rotating column 201g from applying a reverse torsion force to the torsion spring 201j when it rotates in the reverse direction.

[0056] The second spring 203c applies a thrust to the clamping block 203b, so that the clamping block 203b is sufficiently tightly engaged with the clamping slot 201g-2, and the elastic force of the second spring 203c is smaller than the elastic force of the torsion spring 201j.

[0057] Specifically, the locking member 202 includes a limiting column 202a, a third spring 202b and a pull block 202c. A positioning groove 201f-1 is provided in the block 201f. The limiting column 202a is located in the positioning groove 201f-1. The two ends of the third spring 202b are respectively fixed to the limiting column 202a and the inner wall of the positioning groove 201f-1. The pull block 202c is fixed to one side of the limiting column 202a. A limiting hole 201d-1 is provided in the guide rail 201d. The limiting column 202a is engaged with the limiting hole 201d-1.

[0058] The third spring 202b applies a thrust to the limit column 202a, so that the limit column 202a and the limit hole 201d-1 are more tightly engaged, and the two cooperate to lock the stop block 201f, so as to prevent the stop block 201f from moving due to the squeezing of the guide shaft 201e, which will cause the welding angle of the metal plate to deviate.

[0059] One side of the pulling block 202c extends to the outside of the stopper 201f. A movable cavity is provided on the stopper 201f. The pulling block 202c is movably connected to the movable cavity. When the welding angle of the metal plate needs to be adjusted, the pulling block 202c is pulled to drive the limiting column 202a to move, so that the limiting column 202a is separated from the limiting hole 201d-1, thereby releasing the restriction on the stopper 201f, and then the stopper 201f can be moved in the guide rail 201d, so that the welding angle of the metal plate can be adjusted.

[0060] Specifically, there are a plurality of limiting holes 201d-1, which are evenly distributed in the guide rail 201d in an arc shape, and the angle between two adjacent limiting holes 201d-1 is 7.5 degrees.

[0061] By providing a plurality of limiting holes 201d-1, the stopper 201f can be locked at any position in the guide rail 201d, so that the metal plates can be welded at different angles.

[0062] By setting the angle of two adjacent limit holes 201d-1 to 7.5 degrees, the angle adjusted by one block 201f is 7.5, and the angle adjusted by two blocks 201f is 15 degrees, the welding angle of the metal plate is adjusted by 15 degrees each time, which makes it easier for operators to quickly master and perform angle adjustments, reduce the complexity and error rate of operations, and quickly and accurately reach a specific angle, saving adjustment time, improving production efficiency, reducing scrap and rework caused by improper angle adjustment, and reducing production costs.

[0063] Example 3

[0064] Reference Figure 1-Figure 11 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0065] Specifically, it also includes a blocking member 204, which is arranged on one side of the supporting plate 201a, including a baffle 204a, a fixing frame 204b and a fourth spring 204c. A slot 201a-1 is opened on the supporting plate 201a, the baffle 204a is located in the slot 201a-1, the fixing frame 204b is located on one side of the supporting plate 201a, and two ends of the fourth spring 204c are respectively fixed to the baffle 204a and the inner wall of the slot 201a-1.

[0066] The fixing frame 204b is fixed to the inner wall of the positioning frame 205a, one side of the bottom of the baffle 204a is inclined, and the fixing frame 204b is L-shaped.

[0067] When the supporting plate 201a moves, it will drive the baffle 204a to move at the bottom of the fixing frame 204b. The cooperation between the two can block the supporting plate 201a, so that the supporting plate 201a will not rotate upward during the movement, thereby preventing the two metal plates from tilting before they are in contact, which will cause the connection between the two metal plates to be unable to be centered and cause it to shift.

[0068] When the carrying plate 201a stops moving, the baffle 204a will separate from the bottom of the fixing frame 204b, thereby releasing the restriction on the carrying plate 201a, and allowing the carrying plate 201a to rotate upward.

[0069] The fourth spring 204c applies a thrust to the baffle 204a, so that the baffle 204a can always be located on the outside of the supporting plate 201a. By setting the bottom of the baffle 204a inclined, when the supporting plate 201a moves in the reverse direction and rotates downward, the bottom inclined surface of the baffle 204a will be squeezed by the fixing frame 204b and push the baffle 204a to move into the slot 201a-1, so that the supporting plate 201a can rotate downward to the initial state.

[0070] Specifically, it also includes a positioning member 205, which is arranged at the bottom of the guide rail 201d, including a positioning frame 205a and a fifth spring 205b. The positioning frame 205a is located at the bottom of the guide rail 201d, and the two ends of the fifth spring 205b are respectively fixed to the guide rail 201d and the inner wall of the positioning frame 205a.

[0071] The positioning frame 205a is fixed to the top of the base 101, and the guide rail 201d is movably connected to the positioning frame 205a, which is used to position the guide rail 201d to prevent it from shifting during movement. The fifth spring 205b applies thrust to the guide rail 201d, so that the guide rail 201d can move in the opposite direction and reset synchronously with the supporting plate 201a.

[0072] Specifically, it also includes a welding assembly 100, which is connected to the adjustment assembly 200, including a base 101, a support frame 102, a movable frame 103 and a welding mechanism 104. The base 101 is located below the supporting plate 201a, the support frame 102 is fixed to the top of the base 101, the movable frame 103 is arranged on the support frame 102, and the welding mechanism 104 is located on one side of the movable frame 103.

[0073] The rack 201i is fixed to the top of the base 101 through the support legs, and the slide rail 201b is fixed to the top of the base 101 through the stabilizing block.

[0074] The movable frame 103 can move on the support frame 102 and drive the welding mechanism 104 to move. When the two metal plates are connected, the connection between the metal plates can be welded by the welding mechanism 104. This is the prior art and will not be elaborated in this solution. Those skilled in the art can clearly understand the working principle.

[0075] Specifically, the adjustment assembly 200 further includes a cylinder 206 and a connecting block 207 . The cylinder 206 is located on the top of the base 101 . The connecting block 207 is rotatably connected to the bearing plate 201 a . The connecting block 207 is fixed to the output end of the cylinder 206 .

[0076] There are two cylinders 206 and two connecting blocks 207, which correspond to the two supporting plates 201a respectively. When the cylinder 206 is started, the connecting block 207 can be driven to move, so that the supporting plate 201a can be driven to move by the connecting block 207. The connecting block 207 is rotatably connected to the supporting plate 201a through a rotating shaft, and the setting of the connecting block 207 will not affect the normal rotation of the supporting plate 201a.

[0077] In summary, the welding device invented by us has at least the following advantages:

[0078] 1. Ability to weld metal plates at different angles;

[0079] 2. During the welding process, a thrust can be applied to the two metal plates to make the connection between the two metal plates tighter, thus avoiding the existence of welds after welding.

[0080] 3. It can quickly and accurately reach a specific welding angle, saving adjustment time and improving production efficiency.

[0081] During use, when welding the metal plate, the metal plate is placed on the top of the supporting plate 201a. At this time, the first spring 301d applies a downward pulling force to the movable block 301b, and the movable block 301b drives the pressing block 301c to move downward, so that the pressing block 301c can press the metal plate downward, and then the metal plate and the supporting plate 201a can be tightly fitted, and then the cylinder 206 is started to drive the connecting block 207 to move, and the connecting block 207 drives the supporting plate 201a to move.

[0082] When the supporting plate 201a drives the metal plates to move and makes the two metal plates contact, the movement of the supporting plate 201a will make the connection between the two metal plates fit more tightly, thereby avoiding the formation of gaps at the connection between the two metal plates, which will lead to quality problems after welding. When the supporting plate 201a stops moving, the connection between the metal plates can be welded by the welding mechanism 104.

[0083] When the welding is completed and the metal plate needs to be removed, the pressing block 301c is pulled to one side to separate the pressing block 301c from the metal plate, thereby releasing the fixation between the metal plate and the supporting plate 201a, and the welded metal plate can be removed.

[0084] When it is necessary to weld the two metal plates at other angles, it is only necessary to move the block 201f upward in the guide rail 201d and move it to the specified position. At this time, when the supporting plate 201a stops moving and the two metal plates are fully in contact, the fixed shaft 201c can be driven to rotate by the charged torsion spring 201j, and the supporting plate 201a can be driven to rotate upward by the fixed shaft 201c, so that the supporting plate 201a drives the guide shaft 201e to slide in the guide rail 201d, so that the metal plates can be tilted through the supporting plate 201a, and the two metal plates can be welded to other different angles, and the angle of the metal plates can be accurately fixed to ensure that the angle after welding meets the design requirements, reduce quality problems caused by angle deviation, and at the same time, there is no need to frequently change molds or perform manual support, which saves operation time and improves overall production efficiency.
