[0032] The driving mechanism includes a first cylinder 6, which is rotatably connected to the chassis 1 and a first rotating rod 7 is rotatably connected to the front end of the first cylinder 6, the first rotating rod 7 is located between the two first rotating blocks 2 and the first rotating rod 7 is fixedly connected to the two first rotating blocks 2 at the same time;

[0033] The adjusting mechanism includes a second cylinder 8, which is located above the first rotating rod 7 and the bottom end of the second cylinder 8 is fixedly connected to the first rotating rod 7; the upper end of the second cylinder 8 is fixedly connected to a connecting block 9, and the left and right ends of the connecting block 9 are symmetrically rotatably connected to second connecting rods 10, and the left and right second connecting rods 10 are respectively rotatably connected to the first connecting rods 4 at the inner positions of the left and right sides;

[0035] The two first connecting rods 4 between the first rotating block 2 and the second rotating block 3 are equal in length and parallel to each other;

[0036] During operation, the second cylinder 8 is first started according to the length of the automobile beam to be drilled, and the second cylinder 8 drives the connecting block 9 to move up and down. When the connecting block 9 moves upward, the connecting block 9 retracts the two first connecting rods 4 on the left and right sides through the two second connecting rods 10, and the two first connecting rods 4 drive the second rotating block 3 to move closer to each other, and the distance between the left and right electric clamping plates 5 is reduced, which can be used to clamp the automobile beam with a shorter length; conversely, when the second cylinder 8 drives the connecting block 9 to move downward, the electric clamping plates 5 on the left and right sides move away from each other, and the distance between the electric clamping plates 5 on the left and right sides increases, which can be used to clamp the automobile beam with a longer length;

[0037] When the electric clamping plates 5 on the left and right sides are adjusted to a suitable spacing, the first cylinder 6 is started at this time, and the first cylinder 6 pushes the first rotating rod 7 to rotate forward, and the first rotating rod 7 will drive the first rotating blocks 2 on the left and right sides to rotate at the same time.

[0038] After the electric clamping plate 5 clamps the automobile cross beam, the first cylinder 6 is started to shrink and pull the first rotating rod 7 to rotate upward; the two electric clamping plates 5 will drive the automobile cross beam to move upward; when the bevel gear 16 follows the first rotating block 2 to rotate to a position meshing with the incomplete bevel gear ring 17, the bevel gear 16 starts to drive the winding wheel 13 to rotate in the opposite direction, and the winding wheel 13 pulls the second rotating rod 11 through the pull rope, and the second rotating rod 11 drives the electric clamping plate 5 to start rotating relative to the second rotating block 3; when the first rotating rod 7 and the first rotating block 2 are rotated ninety degrees, the electric clamping plate 5 is rotated ninety degrees relative to the second rotating block 3, and the automobile cross beam is at the upper position of the electric clamping plate 5;

[0039] After completing the drilling of the automobile crossbeam, the angle between the first connecting rods 4 on the left and right sides can be reduced by driving the connecting block 9 to rotate upward, and the distance between the electric splints 5 on the left and right sides can be reduced by the first connecting rods 4 on the left and right sides, and then the telescopic rod 18 can be retracted, which can effectively reduce the volume of the overall equipment and the space occupied by the overall equipment, making it easier to move and transport.

[0040] like Figure 6-7As shown, as a further solution of the present invention, the drilling mechanism includes a telescopic rod 18, the telescopic rod 18 is located at the upper rear side of the chassis 1 and the bottom end of the telescopic rod 18 is fixedly connected to the chassis 1, and the telescopic rod 18 has a self-locking property; the upper end of the telescopic rod 18 is fixedly connected to a support frame 19, a lifting frame 20 is provided at the bottom of the support frame 19, and a wire take-up machine 21 is symmetrically fixedly connected to the left and right sides of the support frame 19, a second pull rope 22 is fixedly connected inside the wire take-up machine 21, and the bottom ends of the second pull ropes 22 on the left and right sides are fixedly connected to the lifting frame 20; the lifting frame 20 is fixedly connected to the front and rear sides, the left end of the front third cylinder 23 and the right end of the rear third cylinder 23 are fixedly connected to a connecting frame 24, and the bottom end of the connecting frame 24 is fixedly connected to a drilling machine 25; a stabilizing mechanism is provided at the bottom of the lifting frame 20, and the stabilizing mechanism is used to ensure the stability of drilling by the two drilling machines 25;

The upper end of the stabilizing plate 27 is rotatably connected to a third connecting rod 28, and the upper end of the third connecting rod 28 is rotatably connected to the lifting frame 20.

[0042] During operation, when the automobile beam is at the upper position of the electric clamping plate 5, the wire take-up machines 21 on the left and right sides are started to release the second pull rope 22, and the lifting frame 20 will start to move downward; when the pressing frame 26 at the bottom of the lifting frame 20 moves to contact the center position of the automobile beam, the pressing frame 26 remains stationary when the lifting frame 20 continues to move downward, and the lifting frame 20 pushes the front and rear stabilizing plates 27 to the middle position at the same time through the two second connecting rods 10; when the front and rear stabilizing frames clamp the automobile beam, the lifting frame 20 cannot move downward further; by starting the two third cylinders 23, the front drilling machine 25 can be driven to move to the left and the rear drilling machine 25 can be driven to move to the right respectively; when the front and rear drilling machines 25 move synchronously, the levelness of the entire equipment can be ensured; when the drilling machine 25 moves to a suitable position, drilling can be started;

[0043] When it is necessary to drill a hole at the clamping position of the electric splint 5, the angle between the two first connecting rods 4 on the left and right sides can be changed by opening the two electric splints 5 and starting the second cylinder 8 to drive the connecting block 9 to rise or fall. After the angle between the two first connecting rods 4 on the left and right sides is changed, the spacing between the electric splints 5 on the left and right sides will change, and then the electric splints 5 are driven to clamp the automobile beam again. At this time, the drilling machine 25 can be driven to drill a hole at the position originally clamped by the electric splints 5.
