[0005] Therefore, in view of the above, the existing structure and defects are researched and improved, and a square pipe joint necking machine with fine adjustment mechanism is provided. UTILITY MODEL CONTENTS

[0008] Further, the moving frame comprises a stabilizing frame, a bidirectional screw rod and a second hand wheel, the bidirectional screw rod is horizontally installed on the upper end of the interior of the stabilizing frame, and the second hand wheel is installed on one end of the bidirectional screw rod.

[0009] Further, the moving frame further comprises a guide pipe and a supporting sliding block, the guide pipe is installed on the bottom of the stabilizing frame, and the supporting sliding blocks are symmetrically installed on the two sides of the bottom of the stabilizing frame.

[0010] Further, the guide pipe is in threaded connection with the adjusting screw rod, and the supporting sliding block is in sliding connection with the guide rail.

[0011] Further, the limiting plate comprises a clamping plate, a guide block and an antiskid pad, the guide block is connected to the top of the clamping plate, and the antiskid pad is attached to the surface of the side of the clamping plate close to the vertical central axis of the moving frame.

[0012] Further, the clamping plate and the guide block are in an integrated structure, the guide block is in threaded connection with the bidirectional screw rod, and the top of the guide block is in sliding connection with the inner fixed surface of the stabilizing frame.

[0013] Further, the auxiliary table comprises a material placing table, a supporting frame, a fixed angle plate and a damping sleeve, the supporting frame is connected to the bottom of the material placing table, the fixed angle plates are symmetrically and equidistantly arranged at the joint of the supporting frame and the material placing table, the damping sleeves are installed at the left and right ends of the supporting frame, and the damping sleeves are in sliding connection with one side of the stabilizing frame.

[0015] The square pipe joint necking machine with the fine adjustment mechanism has the following beneficial effects:

[0016] 1. This utility model features an adjustment structure on one side of the operating table. Utilizing a threaded connection between the guide tube and the adjusting screw, along with a sliding connection between the support slider and the guide rail, the adjusting screw, driven by the first handwheel, rotates horizontally. This allows the entire movable frame, equipped with a limit plate and auxiliary platform, to be moved horizontally. This structure enables flexible fine-tuning of the relative distance between the auxiliary platform (installed in the middle of the movable frame) and the main body of the shrinking machine within a certain range. This allows for precise adjustment of the length of the processed end of the square pipe joint, improving processing accuracy. Furthermore, the connection between the placement platform and the support frame, using a fixed angle plate, provides sufficient structural support and stability, ensuring the square pipe joint remains stable when placed on it. The support frame itself, with its sliding connection between the damping sleeves at both ends and the stabilizing frame, allows for arbitrary vertical height adjustment of the auxiliary platform within a certain range, facilitating the docking of the processed square pipe joint with the main body of the shrinking machine.

[0017] 2. This utility model utilizes a threaded connection between a guide block and a bidirectional lead screw above the moving frame. Rotating the second handwheel causes the limiting plates connected to both ends to move horizontally. This allows for flexible adjustment within a certain range according to the size of the square pipe joint being processed, thus achieving structural limitation. This ensures the square pipe joint can be stably inserted and connected to the output end of the shrinking machine. Simultaneously, the anti-slip pad on one side of the clamping plate maximizes friction between the structures during clamping and limiting, preventing slippage and loosening, reducing the impact on processing operations, and effectively ensuring the flexibility and stability of the device structure.
