The sheet metal correction and repair device of the utility model has stable and reliable operation, optimizes the sheet metal correction and repair effect and improves the efficiency.

[0004] The following problems exist in this technical solution:

[0005] Although the sheet metal part can be corrected by the lever principle during use, the sheet metal parts have different sizes, and the distance between the two limiting columns cannot be adjusted, which is not convenient for correcting and repairing sheet metal parts smaller than the distance between the two limiting columns. Content of the Utility Model

[0006] The purpose of the utility model is to solve the disadvantages in the prior art that although the sheet metal part can be corrected by the lever principle during use, the sheet metal parts have different sizes, and the distance between the two limiting columns cannot be adjusted, which is not convenient for correcting and repairing sheet metal parts smaller than the distance between the two limiting columns, and a correction device for sheet metal part repair is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A correction device for repairing sheet metal parts, including a base. A fixed seat is welded to the top of the base. A cavity is provided in the fixed seat. The fixed seat is concave. Grooves are provided on both sides of the top of the fixed seat. The grooves communicate with the cavity. Two limit posts are slidably connected to the bottom inner wall of the cavity. The limit posts are located in the grooves. Circular grooves are provided on both inner walls of the fixed seat. The same rotating rod is rotatably connected to the inner walls of the two circular grooves. A plurality of convex strips are welded on the rotating rod. A movable ring is slidably connected to the rotating rod. A sliding groove adapted to the convex strips is provided on the movable ring. A correction post for correction is welded to one side of the movable ring. A pressing rod for pressing down is welded to one side of the movable ring.

[0009] An adjusting mechanism is arranged in the fixed seat and is used to adjust the distance between the two limit posts.

[0010] A limiting mechanism is arranged on the movable ring and is used to limit the movable ring to prevent it from sliding.

[0011] In a possible design, the adjusting mechanism includes a bidirectional lead screw and a handwheel for facilitating the rotation of the bidirectional lead screw. One end of the bidirectional lead screw is rotatably connected to the inner wall of one side of the cavity. The other end of the bidirectional lead screw penetrates through one side of the fixed seat and is fixedly connected to one end of the handwheel. One side of each of the two limit posts is embedded with a lead screw nut. Both lead screw nuts are threadedly connected to the bidirectional lead screw.

[0012] In a possible design, the limiting mechanism includes a threaded rod for limiting the movable ring to prevent it from moving and a knob for facilitating the rotation of the threaded rod. A threaded hole is provided on the movable ring. The threaded rod is threadedly connected to the threaded hole of the movable ring. The bottom of the knob is fixedly connected to the top end of the threaded rod.

[0013] In a possible design, a rubber sleeve for improving the comfort of the hand is fixedly sleeved on the pressing rod.

[0014] In a possible design, anti-slip lines for increasing the friction of the human hand for anti-slip are provided on the knob.

[0015] In a possible design, mounting holes for facilitating the installation of the base are provided at the four corners of the base.

[0016] In a possible design, a sliding groove for reducing the friction when the limit post moves is provided on the bottom inner wall of the cavity. Sliders are fixedly provided at the bottoms of the two limit posts. The bottoms of the sliders are slidably connected to the inner wall of the sliding groove.

[0017] In this application, when in use, it is first fixed in one place through the mounting holes on the mounting plate, and can be fixed by bolts. Then, according to the size of the sheet metal part, the distance between the two limit posts is adjusted. By rotating the handwheel, the rotation of the handwheel drives the rotation of the bidirectional lead screw, and the rotation of the bidirectional lead screw drives the movement of the two limit posts. Through the bidirectional lead screw, the two limit posts can approach or move away from each other, enabling the two limit posts to limit the sheet metal part. Stop rotating, and thus the distance between the limit posts can be limited, facilitating the correction and repair of sheet metal parts of different sizes. Then, the sheet metal part is placed between the correction post and the limit posts, and subsequently, the sheet metal part can be removed (or not). By rotating the knob, the rotation of the knob drives the rotation of the threaded rod, making the bottom end of the threaded rod closely adhere to the rotating rod, thereby limiting the rotating ring and making it not easy to move. When placing the sheet metal part in the previous position (of course, it is also possible not to use the threaded rod for fixation), then manually move the movable ring to move the movable ring on the rotating rod, align the correction post with the convex part inside the sheet metal part to be repaired, and then manually press the pressure rod to push the correction post outward to press the inner convex part to achieve sheet metal repair and correction. The height of the threaded rod and the knob is lower than the height of the concave part of the fixed seat, making it not easy to affect the sheet metal part. The base, fixed seat, limit posts, rotating rod, movable ring, pressure rod, and correction post are all made of metal materials, such as iron and steel.

[0018] The beneficial effects in this utility model are as follows:

[0019] In this utility model, for the correction device for sheet metal part repair, through the adjustment mechanism, by rotating the handwheel, the rotation of the handwheel drives the rotation of the bidirectional lead screw, and the rotation of the bidirectional lead screw drives the movement of the two limit posts. Through the bidirectional lead screw, the two limit posts can approach or move away from each other, enabling the two limit posts to limit the sheet metal part. Stop rotating, and thus the distance between the limit posts can be limited, facilitating the correction and repair of sheet metal parts of different sizes;

[0020] In this utility model, for the correction device for sheet metal part repair, through the limiting mechanism, by rotating the knob, the rotation of the knob drives the rotation of the threaded rod, making the bottom end of the threaded rod closely adhere to the rotating rod, thereby limiting the rotating ring and making it not easy to move;

[0021] In this utility model, through the adjustment mechanism, the distance between the limit posts can be limited, facilitating the correction and repair of sheet metal parts of different sizes. Through the limiting mechanism, the rotating ring can be limited, making it not easy to move. Description of the Drawings
