Description

Technical Field

[0001] The invention relates to the technical field of semitrailer manufacturing, in particular to a semitrailer compartment assembling and welding device. Background Art

[0002] A semi-trailer is a trailer whose axle is placed at the center of gravity of the vehicle and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. During the manufacturing process of the semi-trailer, the front station plate of the carriage needs to be fixed and welded through a tooling platform. The existing tooling platform has some disadvantages. First, the front station plate of the carriage is large in size and heavy in weight, which makes it inconvenient to move the front station plate of the carriage. Secondly, the front station plates of the carriage of different sizes cannot be used on the same tooling platform, and the deviation of the position of the front station plate of the carriage during the welding process will cause the weld to be too large, making it difficult to weld. The Chinese patent publication number is: CN115302182A discloses "An intelligent carriage welding production line and welding process".

After the assembly is completed, the carriage is transported to the carriage welding station using the carriage welding flow device. The rotary displacement mechanism in the carriage welding station clamps the carriage to be welded, and the gantry robot welding system in the carriage welding station is used to weld the interior of the carriage. After the internal welding is completed, the rotary displacement mechanism adjusts the position of the carriage, and the robot welding system then welds the bottom of the carriage. After the welding of the entire carriage is completed, the carriage is transported to the carriage inspection and repair welding station through the carriage welding flow device for welding quality inspection and repair welding operations.

[0021] The present invention provides a semi-trailer compartment assembly welding device, which has the following beneficial effects:

[0022] 1. The semi-trailer's carriage assembly welding equipment, the bracket is driven to the side of the semi-trailer, then the jack drives the top block to move downward, the top block lifts the bracket, the electric turntable drives the equipment to rotate a quarter of a circle, the top block moves upward to reset, and the driving equipment drives the roller to move closer to the semi-trailer.

[0024] 3. The car body assembly and welding equipment of the semi-trailer, the screw slide and the linear motor are adjusted together, and the welding gun is used to perform linear welding on the panel and the reinforcing ribs. Then, the worm gear continues to rotate upward. In this device, the opening and closing component is arranged below the axis of the semi-shell, so that when the opening and closing component is flipped half a circle, the panel is flipped to the position just above the roof plate of the semi-trailer. The panel passes through the opening and closing component to the edge of the roof plate, which solves the problem of how to accurately position the panel to a certain position in the car body without the need for manual adjustment of the position.

[0025] 4. The semi-trailer's carriage assembly and welding equipment, the two clamping plates are close to each other to clamp the side of the panel, and then the clamping plates drive the panel to move to the position just below the semi-trailer installation point, the frame is driven to flip half a circle, at this time, the top of the original panel is close to the semi-trailer roof, the telescopic rod controls the plug to slide out of the concave block, the locking plate is in an unlocked state, the panel slides to the determined position of the top plate, the hydraulic cylinder drives the bracket to move up, the panel is ready to be placed at the edge of the semi-trailer roof, the panel is rotated and connected to the semi-trailer by a hinge, so that the panel is more stable when installed.

[0026] 5. The semi-trailer's carriage assembly and welding equipment, the panel is driven to flip to the position above the edge of the semi-trailer's roof panel, as the worm gear continues to rotate continuously, the panel moves downward on the side close to the locking plate. Since the panel is thick, it slides down to the surface of the top plate at this time, causing the panel to slide and misalign, resulting in inaccurate alignment. When the surface of the panel is nearly vertical to the ground, the block slides out of the concave block, the gravity of the panel pushes the locking plate to rotate, and the surface of the panel slides out of the frame to the edge of the top plate. The damping of the torsion spring causes the panel to fall slowly, making the panel more accurately aligned to the edge position. BRIEF DESCRIPTION OF THE DRAWINGS

When the rolling direction of the roller 12 is parallel to the axis of the perforated shell 71, the bracket 2 moves to the side position of the semi-trailer and aligns. When the rolling direction of the roller 12 is perpendicular to the axis of the perforated shell 71, the bracket 2 is driven close to the installation position of the semi-trailer panel, so that the panel is driven to the position directly below the installation point of the semi-trailer. At this time, the driving motor 73 drives the worm 74 to rotate, and the worm 74 causes the worm wheel 75 to rotate. A notch is provided at the bottom of the worm wheel 75 so that the panel can slide into the interior of the positioning mechanism 8.

The bottom of the half shell 72 and the perforated shell 71 are both provided with openings. There are two half shells 72, and a cavity is formed between the two half shells 72. The inner side surfaces of the half shells 72 are rotatably connected with a worm 74 and a worm wheel 75, respectively, and the surface of the worm wheel 75 near the opening is fixedly connected with a support plate 76;

[0055] One end of the torsion spring 851 is fixedly installed on the upper position of the surface of the frame 81, and the other end of the torsion spring 851 is fixedly connected to the rotating plate 852. The end face of the rotating plate 852 is rotatably installed on the surface of the frame 81. The opening and closing component 85 also includes a locking plate 853 and a concave block 854. The bottom of the locking plate 853 is fixedly installed near the edge on the side of the rotating plate 852 away from the frame 81, and the concave block 854 is fixedly installed on the outer surface of the rotating plate 852.

The worm gear 75 continues to rotate continuously, and the side of the panel close to the locking plate 853 moves downward. Since the panel is thick, the panel slides down to the surface of the top plate at this time, which will cause the panel to slide out of position and lead to inaccurate alignment. When the surface of the panel is close to perpendicular to the ground, the block 856 slides out of the recessed block 854, and the gravity of the panel pushes the locking plate 853 to rotate. The surface of the panel slides out of the frame 81 to the edge of the top plate. The damping of the torsion spring 851 causes the panel to fall slowly, making the panel more accurately aligned to the edge position.
