Description

Technical Field

[0001] This utility model relates to the technical field of deformation correction, specifically to a welding deformation correction device for a hanging RV body. Background Technology

[0002] The trailer caravan body refers to the main structural part of the trailer caravan. It is usually made of metal materials (such as aluminum alloy, fiberglass, etc.) and adopts a sandwich structure or all-aluminum body design. It has the characteristics of lightweight and high strength. During the production process of the body, welding operations are required. During the welding process, uneven heating of the materials can easily cause certain deformation of the body, which then requires the body to be straightened.

[0003] For example, Chinese utility model patent CN220427224U discloses a welding deformation correction fixture, including a base plate. A worktable and four support rods are fixed to the upper surface of the base plate. A top plate is fixed to the upper surface of the four support rods. A fixing mechanism is provided on the top plate, and an adjustment mechanism is provided on the fixing mechanism. The fixing mechanism includes a box fixed to the upper surface of the top plate. A first motor is fixed to the upper surface of the inner cavity of the box, and a first threaded rod is fixed to the output shaft of the first motor. This welding deformation correction fixture, through the fixing mechanism, allows the first motor to drive the first threaded rod to rotate. The first threaded rod, through a transmission assembly, drives a second threaded rod to rotate, causing a moving plate and the four fixed rods to move together. After the fixed plate abuts against the plate material, the moving plate continues to move. By compressing springs through the fixed rods and the fixed plate, the plate material at two different horizontal positions can be fixed, making the fixing plate more stable in fixing the plate material.

[0004] However, the existing devices are not convenient for correcting different areas of the box, and because the box is large and generally U-shaped, the existing correction devices are not convenient for fixing and supporting the limit, which has certain limitations. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a hanging RV body welding deformation correction device that improves the device's fixing effect on the box, facilitates correction work for boxes of different sizes, increases the correction range and effect of the device on the box, and improves its practicality.

[0006] This utility model discloses a welding deformation correction device for a hanging RV body, comprising a support platform. Two fixing mechanisms are symmetrically arranged at the top of the support platform. Each fixing mechanism includes a fixing plate, the bottom of which is slidably connected to the top of the support platform via a sliding mechanism. A moving mechanism is provided at the bottom of the fixing plate, and a conveying mechanism is provided at the top of the support platform. A sliding plate is slidably mounted on the top of the fixing plate, and a top plate is fixedly mounted on the top of the sliding plate.

The welded body is moved to the top of the support platform by the conveying mechanism, and the body is clamped and fixed by the two fixed plates. The outer and inner walls of the body are moved between the two adjacent correction plates. By rotating the first screw, the connecting plate and moving plate are simultaneously moved longitudinally on the top plate, so that the area to be corrected is located between the two correction plates. By rotating the second screw, the two correction plates are tightly fitted to the correction area of ​​the body, thereby completing the correction of the body. This improves the device's fixing effect on the body, facilitates correction work for body of different sizes, increases the correction range and effect of the device, and improves its practicality.

[0009] Preferably, the clamping mechanism includes a baffle, a plurality of third through holes are provided parallel to each other on the outer side wall of the slide plate, and a plurality of second through holes are provided parallel to each other on the outer side wall of the fixing plate.

They are slidably clamped by the fixing rod and the third through holes and the second through holes, which facilitates the adjustment of the height of the slide plate at the top of the fixing plate.

[0010] Preferably, the sliding mechanism includes a slider, a first through hole is fixedly installed at the bottom end of the fixed plate, and a groove is provided at the top end of the support platform. The slider slides inside the groove. By sliding the slider at the bottom end of the fixed plate on the groove at the top end of the support platform, it is easier for the fixed plate to slide at the top end of the support platform.

[0011] Preferably, a stop block is fixedly installed on the outer side wall of each of the fixed plates, and a limit block is slidably installed inside the slide groove. The limit block and the stop block are tightly fitted together, and the outer side walls of the limit block and the stop block are coated with anti-slip paint.

[0013] Preferably, a first support plate is fixedly installed on the outer side wall of each of the fixed plates, and a second support plate is fixedly installed on the top of the support platform. By installing the first support plate and the second support plate, it is convenient to support the box.

Multiple rotating rollers are rotatably installed on the top of the conveying platform. The installation of the conveying platform facilitates the movement of the box, and the contact between the box and the rotating rollers facilitates the conveying of the box.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This hanging RV body welding deformation correction device uses a sliding plate to connect to the top of the fixed plate, thereby simultaneously driving the top plate, moving plate, and connecting plate to adjust their height. The welded body is moved to the top of the support platform by a conveying mechanism, and the body is clamped and fixed by two fixed plates. The outer and inner walls of the body are moved between two adjacent correction plates. While rotating the first screw, the connecting plate and moving plate are simultaneously moved longitudinally on the top plate, so that the area to be corrected is located between the two correction plates. While rotating the second screw, the two correction plates are tightly fitted to the correction area of ​​the body, thereby completing the correction operation of the body. This improves the device's fixing effect on the body, facilitates correction operations for bodies of different sizes, increases the correction range and effect of the device, and improves its practicality.
