Description

Technical Field

[0001] The utility model relates to the technical field of wrecker production, in particular to a trailer frame welding auxiliary equipment for wrecker production. Background Art

[0002] The full name of the tow truck is road tow truck, also known as trailer, road rescue truck, towing truck, etc. It has many functions such as lifting, pulling and lifting and traction. The tow truck is mainly used for road fault vehicles, urban illegal vehicles and emergency rescue.

[0003] A tow truck is generally converted from a truck, and its loading area is converted into a frame that can be lifted and towed. A limiting device is provided at the end of the frame, and the limiting device at the end of the frame is generally welded and fixed to the frame. The limiting frame at the end of the frame of some vehicles has a certain inclination angle. Therefore, during the welding process of the limiting frame, it is necessary to make the limiting frame contact with the top of one end of the frame at a certain inclination angle to facilitate the welding work. The existing welding process does not have the necessary welding auxiliary means, resulting in the heavier limiting frame being unable to remain relatively fixed to the frame at a certain angle before welding, which makes welding more difficult.

[0025] Specifically, the clamping assembly 1 includes an operating table 11, a limiting tube 12, a clamping plate 13, a clamping screw 14 and a locking knob 15. The limiting tube 12 is fixedly arranged at the ends of both sides of the operating table 11, the clamping plate 13 is clamped inside the limiting tube 12, the clamping screw 14 is fixedly arranged at the bottom of the clamping plate 13, and the locking knob 15 is connected to the clamping screw 14 through a thread. The clamping plate 13 is in a 7-shaped structure, the trailer plate 2 is arranged on the upper surface of the operating table 11, the inner side of the top of the clamping plate 13 is in contact with the upper surface of the trailer plate 2, and the bottom of the clamping screw 14 is in contact with the upper surface of the trailer plate 2. The top cover 415 is in contact with one side of the retaining ring 49, and the inner side of the limiting clamping plate 42 is in contact with the outer end of the trailer board 2. One end of the fixing knob 43 is passed through and extended to the inner side of the bottom of the sleeve 41, and its end is in contact with the bottom end of the trailer board 2.

[0026] In this embodiment, the trailer board 2 is first installed and fixed. After the trailer board 2 is placed on the upper surface of the operating table 11, the fixed end of the limit frame 3 is exposed on one side of the operating table 11, and then the clamping plate 13 is installed, and the bottom of the clamping plate 13 is clamped into the limit tube 12 on the upper surface of the operating table 11. The bottom end of the clamping screw 14 at the bottom of the clamping plate 13 passes through the mounting hole on the surface of the operating table 11, and the locking knob 15 is screwed on its surface. At this time, the inner side of the top of the clamping plate 13 with a 7-shaped structure and the upper surface of the operating table 11 will clamp and fix the trailer board 2. After completing the fixing of the trailer board 2, the limit mechanism 4 is installed.

[0027] Furthermore, the sleeve frame 41 is sleeved on the end of the trailer board 2 exposed from the operating table 11, and the position is adjusted so that the inside of one side of the limiting clamping plate 42 contacts the end of the trailer board 2, and then the fixing knob 43 is tightened to make the top of the fixing knob 43 contact the bottom of the trailer board 2 to achieve a locking effect, and then the limiting frame 3 is clamped on the inner side of the clamping seat 413, and the left and right positions of the limiting frame 3 are adjusted and clamped by rotating the clamping knobs 412 on both sides, and then the top cover 415 is rotated outward to screw the locking screw 416 on one side out of the connecting shaft 46. At this time, the connecting frame 414 can be held by hand to pull the bottom clamping ring 49 of the support rod 410 out of the surface of the gear ring 47, and the inclination angle of the limiting frame 3 to be welded can be rotated to adjust. After completion, push the connecting frame 414 forward so that the inner tooth groove of the retaining ring 49 meshes with the surface teeth of the gear ring 47 again and screws in the top cover 415. As the locking screw 416 is screwed in at the end of the connecting shaft 46, the top cover 415 moves forward until its end contacts the outer side of the retaining ring 49, thereby playing a limiting role to prevent the retaining ring 49 from detaching from the surface of the gear ring 47 during operation. Finally, operate the adjusting knob 411 according to the welding position. Rotating the adjusting knob 411 can mainly control the forward and backward sliding of the sliding block 45 in the guide frame 44, thereby adjusting the position of the clamped limit frame 3 to ensure that the welding position of the limit frame 3 is located at the end of the trailer board 2. In this way, the limit frame 3 is fixed to the end of the trailer board 2 at a rated angle, thereby facilitating the welding work.
