The horizontal plate 31 is horizontally slidable on the base 10 and is connected to the first cylinder 36. Since the first cylinder 36 is fixed to the base 10, when the piston of the first cylinder 36 moves, the horizontal plate 31 slides under the driving of the first cylinder 36. The horizontal plate is referred to as a horizontal plate because it is parallel to the horizontal plane for locating the orientation of the other individual components. It will be understood, of course, that the horizontal plate 31 need not be parallel to the horizontal plane when the two-dimensional movement mechanism 30 is provided or when the bending jig 100 for an a-pillar assembly is provided. The vertical plate 32 is perpendicular to the horizontal plate 31 and is fixed to the horizontal plate 31. It will be appreciated that the vertical plate 32 is also named with respect to the horizontal plate 31. The vertical sliding plate 33 is slidably provided on the vertical plate 32 to slide up and down along the vertical plate 32 by a second cylinder 37 provided on the horizontal plate 31. The L-shaped cantilever 34 is fixedly provided on the vertical sliding plate 33, and one side of the L-shaped cantilever 34 is vertically fixedly provided on the desired vertical sliding plate 33, and the other side extends toward the horizontal plate 31, thereby forming a "nose-like" shape. The first rail assembly 35 is disposed on one side of the L-shaped cantilever 34 fixed to the vertical sliding plate 33, and is disposed on a side facing the horizontal plate 31. The first rail assembly 35 includes a first rail 351 provided on the L-shaped cantilever 34, and a first slider 352 slidably hung on the first rail 351.

The third rail assembly 39 includes a third rail 391 fixedly disposed on the vertical plate 32 and a third slider 392 slidably disposed on the third rail 391. The third slider 392 is fixed to the vertical sliding plate 33 so that the vertical sliding plate 33 can slide along the third guide rail 391. It should be understood that the first, second and third rail assemblies 35, 38, 39 should be known to those skilled in the art, and the structure and operation thereof will not be described herein. The construction and operation of the first and second cylinders 36, 37 themselves should also be well known to those skilled in the art, and will not be described in detail herein.
The pressure supporting device 40 is fixedly arranged on the two-dimensional moving mechanism 30, and specifically, the pressure supporting device 40 is fixedly arranged on the free end of the L-shaped cantilever 34 of the two-dimensional moving mechanism 30. The holding and pressing device 40 is a holding and pressing block 41 arranged at the free end of the L-shaped cantilever 34, and a fastener 42 for fixing the holding and pressing block 41. The supporting and pressing block 41 comprises an abutting surface 43 for abutting against the A-pillar assembly 200 and a lower bending die 44. The abutting surface 43 has the same structure as the abutting surface 21, and clamps the a-pillar assembly 200 together with the abutting surface 21 for bending and welding. In operation, the a-pillar assembly 200 is first placed on the backing block 20, and then the first and second cylinders 36 and 37 are actuated to press the backing block 41 against the other side of the a-pillar assembly 200, thereby clamping the a-pillar assembly 200. The lower bending die 44 is used for setting the bending angle of the L-shaped small ear 201. In this embodiment, the bending angle of the L-shaped small ear 201 is 90 degrees, so the bending lower die 44 is a plane.
The bending device 50 is slidably disposed on one side of the L-shaped cantilever 34 and the vertical sliding plate 33, specifically, the bending device 50 is slidably hung on the first rail assembly 35, that is, the bending device 50 is fixedly disposed on the first slider 352 of the first rail assembly 35. The bending device 50 includes a connection block 51 slidably mounted on the first rail assembly 35, a bending press block 52 disposed on the connection block 51, and a third cylinder 53 fixedly disposed on the vertical sliding plate 33 and connected to the connection block 51. When the a-pillar assembly 200 is sandwiched between the backing block 20 and the backing block 41, the third cylinder 53 pushes the connection block 51 to make the bending press block 52 press the L-shaped small ear 201 which is not bent. That is, when the backing block 21 is abutted against one side of the a-pillar assembly 200 and the abutment surface 43 of the support block 41 of the support device 40 is abutted against the other side of the a-pillar assembly 200, the connection block 51 slides to push the bending press block 52 to press the small ear 201 against the bending lower die 44 of the support block 41 to bend the small ear 201. The bending press 52 is provided on the connection block 51 to be replaced according to a different type of a-pillar assembly 200, so that the compatibility of the bending jig 100 for a-pillar assembly can be improved.

It is conceivable that the welding bending system further comprises other functional modules, such as assembly components, electrical components, control devices, etc., which are known to the person skilled in the art and are not described here in detail.
The machine 300 is configured to carry the above functional modules, which may be a flat plate, and determine the shape and size according to actual needs, which are not described herein.
The driving device 400 includes a fourth rail assembly 401 disposed on the machine 300, a guide plate 402 disposed on the fourth rail assembly 401, a fourth cylinder 403 disposed on the machine 300, and a connecting rod 404 connecting the fourth cylinder 403 and the guide plate 402. The fourth rail assembly 401 includes two fourth rails 405 disposed on the machine 300 at intervals and a fourth slider 406 disposed on the guide plate 402. The guide plate 402 is used for fixing the bending fixture 100 for the a-pillar assembly. The bending jig 100 for the a-pillar assembly can reach where it should be driven by the driving device 400.
The welding apparatus 500 should be of a technology known to those skilled in the art having a welding gun for welding the front and rear sections or other components of the a-pillar assembly 200. After the bending jig 100 completes the bending process for the small ear 201 of the a-pillar assembly 200, the driving device 400 drives the bending jig 100 for the a-pillar assembly to be far away from the welding device 500 and the welding device 500 welds the a-pillar assembly 100. When the welding is completed and the next bending or clamping of the a-pillar assembly is required, the bending fixture 100 for the a-pillar assembly is pushed back to the original position by the driving device 500 for the next bending process.
Compared with the prior art, the bending fixture 100 for the A-pillar assembly provided by the invention is provided with the backing block 20, the supporting device 40 and the bending device 50 arranged on the two-dimensional moving mechanism 30, so that after the backing block 20 and the supporting device 40 press the A-pillar assembly 200, the bending device 50 bends the L-shaped small ear 201, and the bending of the L-shaped small ear 201 can be completed on an oil hydraulic workstation. After bending the L-shaped small ear 201, the driving device 400 in the welding bending system pushes the bending clamp 100 to be away from the position of the welding device, so that the work of the welding device 500 is prevented from being influenced, and meanwhile, the A-pillar assembly 200 is clamped by the bending clamp 100 during welding without changing the clamp and a workstation, so that the production efficiency can be improved, the greasy dirt is reduced, and the labor cost is reduced.
The above is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions or improvements within the spirit of the present invention are intended to be covered by the claims of the present invention.
