Specifically, tilting mechanism 5 includes upset motor 51, lifting platform 56, block 513 and connecting plate, lifting platform 56 installs the one end at the bottom plate, and lifting platform 56's top installs upset motor 51, upset motor 51 passes through axis of rotation 511 and is connected with block 513, axis of rotation 511 runs through the setting in the connecting plate, and installs block 513 in the connecting plate outside, be provided with movable fixture block 512 on the axis of rotation 511, the top of block 513 is provided with clamp plate 53, and clamp plate 53's top installs cylinder 52, the both sides of block 513 are provided with shifting chute 54, cooperation piece 55 is installed to the other one end of connecting plate, be provided with two spread grooves in the connecting plate, be connected through movable block 57 between clamp plate 53 and the connecting plate.

When the clamping mechanism 4 is used for placing a frame between the pressing plates 53, the clamping seat 513 can be collided under the action of the frame to be displaced, when the clamping seat 513 is displaced to a certain degree, the rotating shaft 511 arranged on one side of the clamping seat 513 can be inserted into the clamping seat 513, meanwhile, the clamping seat 513 is displaced due to the fact that the position of the clamping seat 513 is displaced, the clamping seat 513 does not act on the pressing plates 53 any more, the pressing plates 53 can be displaced, the pressing plates 53 move downwards under the action of the air cylinders 52 and clamp the frame, after clamping is completed, the clamping blocks 46 are opened, the lifting table 56 is lifted, the frame can be overturned under the action of the overturning motor 51, clamping force of the pressing plates 53 on the frame can be guaranteed in the overturning process, and the safety of the device is improved.

Specifically, a mounting groove 58 is formed in the lifting table 56, a pressing block 59 is mounted in the mounting groove 58, one end of the pressing block 59 is connected with a top block 591, and the top block 591 penetrates through the lifting table 56.

During operation, along with lifting platform 56 constantly rises, lifting platform 56 can insert in mounting groove 58, thereby promote extrusion piece 59, extrusion piece 59 receives the extrusion and makes top piece 591 ejecting, when top piece 591 is ejecting, when the connecting plate is rotatory under upset motor 51's drive, when rotatory to certain angle, the cooperation piece 55 that sets up in connecting plate one end can be extruded each other with top piece 591, along with constantly extrudeing between cooperation piece 55 and the top piece 591, make block 513 drop from axis of rotation 511, thereby reach the frame and overturn the effect that just stops the upset a week, be convenient for carry out following welding work.

Specifically, the clamping seat 513 is provided with connecting blocks at two ends thereof, the connecting blocks are matched with the connecting grooves for use, the clamping seat 513 is connected with the connecting plates through a matching spring 514, the clamping seat 513 is located at one end of the rotating shaft 511, a clamping groove is formed in one end of the rotating shaft 511, and the clamping groove is connected with the movable clamping block 512 in a clamping mode.

In operation, along with the removal of grip block 46, make the frame contradict the block holder 513 and make it take place the displacement, because the block holder 513 moves inwards, thereby make the block holder 513 be connected with axis of rotation 511, upset motor 51 is rotatory tentatively, make activity fixture block 512 card go into the draw-in groove that sets up in block holder 513, block holder 513 can rotate under upset motor 51's drive, thereby can effectively avoid workman's maloperation to lead to upset motor 51 to drive clamp plate 53 and rotate, lead to the injured condition of workman to take place, and in the in-process that uses, when block holder 513 moves inwards to the certain distance, clamp plate 53 just can carry out the centre gripping to the frame, avoid frame clamping position to install not in place, the workman just begins to turn over the frame, the unexpected condition that drops appears in the frame takes place.

Specifically, the welding mechanism 7 includes a placing seat 71 and a welder 72, sliding blocks 73 are disposed at two ends of the bottom of the placing seat 71, the sliding blocks 73 are slidably connected with the sliding grooves 11, and the welder 72 is disposed at the upper end of the placing seat 71.

During operation, the workman can be as required welded position, adjusts the position of placing seat 71, avoids welder 72 to drag the removal around the frame round trip movement, increases workman's intensity of labour, simultaneously because welder 72 has special welding position for welder 72 is convenient for seek welder 72 when welding, simultaneously because place seat 71 for the liftable formula, the welder of the different heights of being convenient for uses.

Specifically, the contact surface of the extrusion block 59 and the extrusion seat 6 is designed to be an inclined surface.

During operation, as the contact surface of the extrusion block 59 and the extrusion seat 6 is an inclined surface, the process of extrusion matching can be more smooth, and the extrusion of the top block 591 is facilitated.

Specifically, the cross-sections of the moving block 57 and the moving groove 54 are T-shaped.

During operation, because the cross sections of the moving block 57 and the moving groove 54 are T-shaped, when the pressing plate 53 clamps and fixes the frame, the falling-off condition between the pressing plate 53 and the connecting plate can be avoided in the overturning process, and therefore the safety of workers is improved.

Working principle; firstly, a vehicle frame to be welded is placed on the lifting platform 3, then the distance between the first sliding seats 23 is adjusted by adjusting the first screw rod 22, so that the distance between the first sliding seats 23 and the second sliding seats 24 is continuously reduced along with the adjustment of the first screw rod 22 until the clamping of the vehicle frame is completed, in the clamping process, the clamping blocks 46 are respectively arranged at the inner sides of the first sliding seats 23, so that the clamping blocks 46 can clamp the vehicle frame, after the clamping is completed, the lifting platform 3 descends, a worker enters the base 1 to start the welding of the vehicle frame, in the welding process, the welding worker pulls the placing seat 71, so that the placing seat 71 can perform position adjustment, the welding of different welding points is convenient, in the adjusting process, the placing seat 71 slides along the sliding groove 11, so as to achieve the position adjusting process, and in the sliding seat, the sliding block 73 is arranged, the sliding block 73 is cylindrical, so that the placing seat 71 can move smoothly during the moving process, when one surface of the base 1 is welded and the reverse surface of the frame needs to be welded, the second screw 45 is controlled to drive the clamping block 46 to move, the frame can move under the drive of the clamping block 46, so that the frame can move into the pressing plate 53, when the frame moves into the pressing plate 53, the frame can be extruded to the clamping seat 513, so that the clamping seat 513 moves inwards, after the clamping seat 513 moves inwards, the pressing plate 53 clamps the frame under the action of the air cylinder 52, after the frame is clamped by the pressing plate 53, and simultaneously, due to the inward movement of the clamping seat 513, the rotating shaft 511 is clamped into a clamping groove arranged in the clamping seat 513, so that the rotating shaft 511 can drive the pressing plate 53 to rotate during the rotating process, so as to drive the frame to rotate, after the rotating shaft 511 is inserted, the lifting table 56 lifts the overturning motor 51, in the lifting process, the extrusion seat 6 can be inserted into the placing hole, so that the top block 591 arranged in the placing hole is ejected out, after the top block 591 is ejected out, the overturning motor 51 works, under the action of the overturning motor 51, the pressing plate 53 rotates to drive the frame to overturn, after the frame is overturned to a certain angle, the top block 591 abuts against the matching block 55, so that the clamping seat 513 falls off from the rotating shaft 511, so that the connecting plate stops overturning, the frame is overturned, after the frame is overturned, the lifting table 56 descends, the clamping block 46 is controlled again to clamp the frame, after the clamping is finished, the position of the frame is adjusted through the second screw rod 45, and the second surface is welded.
