Single-card pipe cutting machine servo motor calibration mechanism

Abstract

This utility model belongs to the field of manufacturing and assembly technology, and particularly relates to a servo motor correction mechanism for a single-clamp pipe cutter. It includes a Y-axis slide plate and a Delta motor. A guide rail is mounted on the top of the Y-axis slide plate, and the bottom of the guide rail is connected to the top of the Y-axis slide plate. This servo motor correction mechanism for a single-clamp pipe cutter achieves a transmission combination of a second drive motor (servo motor) and a bidirectional lead screw. The reverse thread of the bidirectional lead screw drives two sets of sliding blocks (sliding block three and sliding block four) to move synchronously in opposite directions, causing the pull claw, bearing roller, and iron pull claw to form a stable clamping of the pipe. The iron pull claw makes rigid compression contact with the pipe, and with the rolling guidance of the bearing roller, it ensures stable clamping of heavy pipes weighing ≤50kg, while preventing relative sliding between the pipe and the clamping components. This achieves synchronous movement of the cutting head and the clamping correction assembly, and allows for quick and convenient adjustment of the cutting head's height and lateral position.

Description

Technical Field

[0001] This utility model relates to the field of manufacturing and assembly technology, specifically to a servo motor correction mechanism for a single-card pipe cutting machine. Background Technology

[0002] As a core pipe processing equipment in the manufacturing and assembly field, the single-clamp pipe cutter is widely used in many industries such as building materials, machinery manufacturing, home appliance production, and auto parts processing. Its core function is to achieve precise cutting of various pipes such as round pipes and square pipes at a fixed length and angle, which is a key pre-processing step for subsequent pipe welding and assembly.

[0003] The existing servo motor correction mechanism of the single-clamp pipe cutter usually involves adding a set of servo motor correction mechanisms with multiple rows of bearing rollers behind the cutting head to correct the pipe. However, in actual use, the pipe material cannot be too thick and can only be processed on thin pipe materials. If the pipe material is too thick, the servo motor clamping will be unstable, which will lead to the servo motor overload alarm. In addition, the weight of the pipe material cannot be too heavy, as it will cause the pipe to slip.

[0004] Therefore, we urgently need to provide a servo motor calibration mechanism for single-card pipe cutting machines. Utility Model Content

A pull claw 19 is fixedly installed at the bottom of the connecting plate 16. The top of the pull claw 19 is connected to the bottom of the connecting plate 16. A mounting plate 20 is provided on one side of the pull claw 19. One side of the mounting plate 20 is connected to one side of the pull claw 19.

A chuck assembly 25 is provided on one side of the Y-axis slide plate 1.

[0018] Working principle: Pipe conveying: The chuck assembly 25 pushes the pipe to be cut along the conveying path. The pipe is first initially positioned by the pull claw 19, and then enters between the two sets of iron pull claws 22 of the clamping and correction assembly. The main controller detects the curvature of the pipe (through the vision detection module or displacement sensor built into the pipe cutter). If there is a bend, the drive motor 2 13 is started, which drives the bidirectional screw 14 to rotate. The rotation of the bidirectional screw 14 drives the sliding block 3 15 to move. The movement of the sliding block 3 15 drives the sliding block 4 17 to move synchronously towards each other along the guide rail 3 18. The bearing roller 21 on one side of the pull claw 19 clamps the pipe until the center of the pipe is aligned with the center of the cutting head 11. When the cutting head 11 is started, the main controller controls the control motor 2 to drive the Y-axis slide plate 1 to move, which drives the cutting head 11 to cut along the pipe axis; at the same time, the drive motor 2 13 synchronously drives the bidirectional lead screw 14, so that the clamping and correction assembly moves synchronously with the cutting head 11, always keeping the center of the pipe aligned with the center of the cutting head 11. When it is necessary to adjust the height of the cutting head 11, the drive motor 8 is started to drive its matching threaded rod to rotate. The rotation of the threaded rod causes the sliding block 9 to slide on the guide rail 7. The sliding block 9 causes the fixed seat 10 to move. The movement of the fixed seat 10 causes the cutting head 11 to move, thereby enabling the height of the cutting head 11 to be adjusted quickly and conveniently, and thus enabling better cutting of square tubes 24 of different sizes. When it is necessary to adjust the position of the cutting head 11 left or right, the motor matching the guide rail 3 is started. The motor drives the matching threaded rod to rotate, and the rotation of the threaded rod drives the sliding block 4 to slide on the guide rail 3. The movement of the sliding block 4 can indirectly drive the cutting head 11 to move, so that the position of the cutting head 11 can be adjusted quickly and conveniently, and thus better processing can be performed. After cutting, drive motor 213 rotates in the opposite direction, sliding block 315 and sliding block 417 move in opposite directions to release the pipe; chuck assembly 25 sends out the cut pipe, the mechanism resets, and it is ready to process the next pipe.
