Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing, and in particular to a positioning device for steel pipe processing. Background Technology

[0002] An existing patent (publication number: CN220740029U) discloses a positioning device for locking steel pipes in a pipe curtain process. This device includes a male and female locking mechanism, a processing platform, and a male locking positioning component for positioning the male locking mechanism. The male locking positioning component consists of two symmetrically distributed male locking baffles, with the male locking mechanism positioned between the two baffles. A pipe curtain steel pipe is mounted on the male locking baffles. A female locking positioning component for positioning the female locking mechanism is mounted on the outside of the pipe curtain steel pipe, and this component consists of multiple female locking positioning clamps. However, this device can only fix the steel pipe and cannot axially rotate the steel pipe according to the actual processing requirements. This results in inconvenience for processing the lower part of the steel pipe, reducing the efficiency of steel pipe processing and presenting a drawback. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a flexible structural positioning device for steel pipe processing. This device allows for adjustment of the inner diameter of the support according to the actual diameter of the steel pipe, meeting the support requirements of different specifications and models of steel pipes. It ensures accurate processing position, improves steel pipe processing precision and finished product quality, has a wide range of applications, and is highly practical. Furthermore, by driving the steel pipe to rotate, it changes the axial processing position of the steel pipe, facilitating processing operations on the lower side of the steel pipe, reducing operational difficulty, and improving the efficiency of steel pipe processing.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A positioning device for steel pipe processing includes a rotating sleeve, a worm gear, a worm, a mounting plate, a fixed plate, a positioning plate, a control rod, and a control sleeve. The rotating sleeve has positioning sleeves on both sides and a worm gear in the middle. The worm gear is adapted to the worm and connects to it. The worm connects to the interior of a lower bearing. The mounting plate connects to the exterior of the lower bearing. A fixed base plate connects to the lower part of the mounting plate. A motor connects to the exterior of the mounting plate and is connected to the worm. The rotating sleeve connects to the interior of an upper bearing. The fixed plate connects to the exterior of the upper bearing and is connected to the fixed base plate.

[0006] The positioning support plate of this utility model is connected to an anti-slip rubber pad on its inner side, which is connected to a steel pipe. The positioning support plate has a positioning support rod on its outer side, which is connected to a positioning support sleeve. The positioning support rod has a connecting rod, which is connected to the inside of an inner bearing. The inner bearing is connected to a control sleeve on its outer side, and the control sleeve fits into the positioning support sleeve.

[0007] The positioning sleeve of this utility model has a sliding hole, and the control sleeve has a control rod groove. The control rod groove and the sliding hole are adapted to the control rod. The control rod passes through the sliding hole, and the inner end of the control rod is connected to the control rod groove by a thread. The positioning sleeve has multiple locking grooves, which are adapted to the control rod, and the control rod is connected to the locking grooves. Beneficial effects

[0008] During the processing of steel pipes, this utility model first places the pipe into a rotating sleeve, and then positions and supports it on both sides using positioning plates to prevent the steel pipe from shifting or deviating during processing, ensuring accurate processing position, facilitating welding, drilling, and other processing operations, improving the processing precision and finished product quality. Furthermore, by engaging a control rod in a locking groove, the inner diameter of the support between the two positioning plates is braked and adjusted to meet the support requirements of steel pipes of different specifications and sizes, expanding its applicability and practical performance. The structure is flexible and the operation is convenient.

[0009] The worm gear and worm wheel of this utility model are positioned and connected, so that when the motor drives the worm gear to rotate, the worm wheel and the rotating sleeve will move together and rotate axially to the steel pipe processing position. This facilitates the processing operation on the lower side of the steel pipe, reduces the difficulty of operation, and eliminates the need to repeatedly disassemble and fix the steel pipe to change the axial processing position of the steel pipe. The structure is flexible and improves the efficiency of steel pipe processing.

[0010] This utility model has a flexible structure and can adjust the inner diameter of the support according to the actual diameter of the steel pipe to meet the support requirements of steel pipes of different specifications and models. It ensures accurate processing position, improves the processing accuracy and finished product quality of steel pipes, has a wide range of applications and strong practicality. At the same time, by driving the steel pipe to rotate, the axial processing position of the steel pipe can be changed, which facilitates the processing operation on the lower side of the steel pipe, reduces the difficulty of operation, and improves the efficiency of steel pipe processing.
