As an embodiment of the present invention, as shown in fig. 6, theball 53 is made of hard rubber, and a slide block 6 is fixedly installed at a middle position of one outer surface of theball 53, and the slide block 6 is slidably connected to an inner surface of the half ball sleeve 54 inside a sliding groove 61 adapted to the inner surface.
When the plate welding device works, when the plate body is welded, the semi-spherical sleeve 54 can be pushed backwards firstly, the abuttingball 53 is compressed, the two groups of semi-spherical sleeves 54 corresponding to each other in the front and the back are separated, then the semi-spherical sleeves 54 are rotated upwards or downwards, the sliding block 6 slides in the sliding groove 61, the straight surface of the semi-spherical sleeve 54 faces upwards or downwards, the two groups of abuttingballs 53 opposite in the front and the back are staggered, the front and the back secondmagnetic blocks 531 lose the mutual attraction, and therefore the front and the back two groups of clampingmechanisms 3 lose the attraction and can be dragged at will.
The working principle is as follows: when the metal plate clamping device works, firstly, two groups of metal plates to be welded are respectively clamped in two groups of clamping mechanisms 3, when in clamping, the bottom of each metal plate is clamped in the clamping frame 35 at the lower end, because certain gravity exists in the metal plates, when the metal plates are clamped in the trapezoidal groove 351, the lower ends of the metal plates abut against the abutting plates 354, the abutting plates 354 sink and compress the buffer bag 355 until the abutting plates 354 are clamped to the positions matched with the inside of the trapezoidal groove 351, the abutting plates 354 are clamped and stop moving, when the abutting plates 354 move downwards along with the gravity of the metal plates, the abutting plates 354 pull the abutting springs 353, so that the included angle ends of the two groups of arc-shaped clamping plates 352 are forced to be close to and clamp the metal plates, the bottom of the metal plates is limited, when the metal plates are preliminarily limited, one side of the metal plate to be welded is pushed out to the position of 3-5 cm on one side of the clamping frame 35, and then, the position of the clamping frame 35 at the upper ends of the metal plates is adjusted according to the whole height, when adjusting, the distance between the two sets of movable plates 31 can be adjusted, the connection between the two sets of movable plates 31 and the connection at the included angle of the movable plates 31 are hinged through the hinge shaft, when the two sets of movable plates 31 need to be lengthened, the plate body connecting the movable plates 31 and the clamping frame 35 is directly pushed upwards or downwards, when the angle of the movable plates 31 is enlarged, the plate body of the movable plates 31 is lengthened, the upper clamping frame 35 is upwards along with the plate body, and the distance between the upper and lower clamping frames 35 is enlarged, so as to adapt to higher sheet metal clamping; on the contrary, when the angle of the movable plate 31 is reduced, the plate body of the movable plate 31 faces downward, the upper end clamping frame 35 faces downward, the distance between the upper and lower groups of clamping frames 35 is shortened, when the upper end clamping frame 35 is adjusted to a proper position, the upper end of the metal plate is clamped in the clamping frame 35, the movable plate 31 is pulled downward, the clamping frame 35 faces downward, the abutting plate 354 contacts and abuts against the metal plate, the abutting plate 354 is forced to abut against the buffer bag 355 and simultaneously the abutting plate 354 pulls the abutting spring 353, so that the included angle ends of the two groups of arc-shaped clamping plates 352 are forced to approach to and clamp the metal plate, the bottom of the metal plate is limited, the other group of metal plate is limited in the clamping mechanism 3 according to the above manner, the two groups of metal plates are limited, the clamping mechanism 3 is pushed towards the middle respectively until the front and rear groups of metal plates are abutted against and aligned, the front and rear opposite hemispherical sleeves 54 are mutually attracted by the second magnetic blocks 531, the two groups of clamping mechanisms 3 are limited together with the clamped sheet metal, the two groups of resisting mechanisms 5 are contacted and collided firstly, so that the cross rod 51 is forced to advance towards the interior of the cylinder 36, the spring group 52 is compressed, the two groups of clamping mechanisms 3 are drawn close, when the cross rod 51 is impacted and moves towards the cylinder 36, one end of the resisting rod 512 loses the inner wall of the cylinder 36 to resist and is separated from the groove 511, the rotating ball 513 rotates, one end of the resisting rod 512 moves downwards and penetrates through the through groove 361 until being clamped in a gap between the first round ball 41 and the second round ball 42, at the moment, the resisting rod 512 is inclined, the bottom of the resisting rod is clamped and resisted in the limiting component 4 and is matched with the limiting rod 362, the clamping mechanisms 3 cannot move forwards and backwards after being limited, so that the welding can be carried out, when the welding of the sheet metal is finished, the upper end movable plate 31 can be pushed upwards, the angle of the movable plate 31 is enlarged, the clamping frame 35 at the upper end is separated from the metal plate, and then the clamping frame 35 at the lower end is also separated from the metal plate in the same way, so that the welded metal plate can be taken out.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
