Description

Technical Field

[0001] This utility model relates to the field of welding robot technology, and more specifically, to an adjustable welding robot. Background Technology

[0002] Welding robots are industrial robots used for welding. According to the International Organization for Standardization's definition of industrial robots as standard welding robots, an industrial robot is a multi-purpose, reprogrammable, automatically controlled manipulator with three or more programmable axes, used in the field of industrial automation. To adapt to different applications, the mechanical interface of the robot's last axis is usually a connecting flange, which can be used to attach different tools or end effectors. Welding robots are industrial robots with welding guns or welding torches attached to the flange of the last axis, enabling them to perform welding, cutting, or thermal spraying. Welding robots mainly consist of two parts: the robot and the welding equipment. The robot consists of the robot body and the control cabinet.

[0003] As disclosed in Publication No. CN213410871U, an adjustable welding robot includes an adjustment box. A control panel is fixedly connected to the front of the adjustment box. A groove is formed on the upper surface of the adjustment box, and a rotating disk is located inside the groove. A sliding tube is fixedly connected to the upper surface of the rotating disk, and a sliding sleeve is fitted onto the outer surface of the sliding tube. A fixing plate is fixedly connected to the right side of the sliding sleeve, and a robotic arm is fixedly mounted on the right side of the fixing plate. A welding mechanism is fixedly connected to the right end of the robotic arm, and a drive motor is fixedly connected inside the adjustment box. This adjustable welding robot, through the drive motor driving the rotating shaft to rotate in conjunction with the rotating disk, allows the rotating disk to adjust the direction of the welding robot. Utilizing the sliding sleeve in conjunction with the sliding plate and the sliding tube, the height of the robotic arm can be adjusted under the action of an electric push rod, facilitating use. The robotic arm, in conjunction with the welding mechanism, allows for control of the welding movement.

[0004] However, the welding robot disclosed above is prone to tangling and accumulating electrical wires due to the constant changes in welding angle during the welding process, which can lead to circuit damage. Therefore, it is necessary to propose an adjustable welding robot. Utility Model Content

[0031] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0032] 1. This utility model, through the cooperation of the mounting base, movable frame, adjusting frame, and winding frame, realizes an adjustable welding robot. The wire passes sequentially through the movable sleeve and exits from the winding drum, where it is tightly wound around the surface. During the operation of the welding mechanism, the tensile force generated by frequent angle changes can easily cause the wire to detach from the winding drum. However, when the welding mechanism completes its rotation, the winding drum rotates synchronously under the elastic potential energy of the torsion spring, orderly winding the slack wire back onto the drum surface. This design effectively avoids the problem of wire entanglement and accumulation caused by angle changes during welding operations, significantly improving the safety and reliability of the wiring under complex working conditions and providing excellent protection for the wire.

[0035] 4. In this utility model, the supporting tie rod is provided to support the adjustment frame, ensuring the stability of the device during operation and preventing the device from tipping over due to an unstable center of gravity. Attached Figure Description

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] like Figs. 1-3 As shown, an adjustable welding robot is described. This equipment adopts a modular design, and its core components include four major systems: a mounting base 1, a movable frame 2, an adjustable frame 3, and a winding frame 4. Each module achieves coordinated operation through precision mechanical transmission. The specific structure is as follows:

[0043] I. Basic Support System

[0044] The mounting base 1 serves as the foundation of the equipment, with a movable slot 5 on the top and an integrated adjustment motor 7 on the left side. The motor output shaft is rigidly connected to the adjusting threaded rod 6 within the movable slot, providing the starting point for power transmission to the equipment.

[0045] The bottom of the movable frame 2 is fixedly connected to the movable block 8, which cooperates with the adjusting threaded rod 6 through the threaded pair to achieve linear displacement along the movable groove 5. The top is equipped with a mounting plate 9 and a rotary motor 10, which drives the mounting plate 9 to complete a 360° rotation.

[0046] II. Dynamic Adjustment System

[0047] The adjustment frame 3 is installed on the top of the movable frame 2 and integrates the conversion turntable 11 assembly inside. The conversion turntable 11 has a fixed conversion gear 12 on its surface, which meshes with the transmission gear 13 below and is driven by the top transmission motor 14 to achieve ±180° angle adjustment.

[0048] Actuator: A fixed plate 15 extends from the right side of the conversion turntable 11, which is equipped with a robotic arm 16 and a welding mechanism 17 to complete precision welding operations; at the same time, a tray frame 18 is provided to support the winding device.

[0049] III. Rewinding Execution System

[0050] The winding rack 4 adopts a split design:

[0051] Support assembly: The support frame 401 and the movable sleeve 402 form a sliding pair, providing axial freedom of movement.

[0052] Winding assembly: The spool 403 is hinged to the support frame 401 via a rotating shaft and has a built-in torsion spring 404 to realize the automatic winding and unwinding function.

[0053] IV. Auxiliary Connection System

[0054] Linkage structure: The top connecting block 19 of the mounting plate 9 forms a triangular support with the adjusting frame 3 through the support rod 20, which enhances the rigidity of the system.

[0055] Control center: The control box 21 is set on the top of the mounting base, which integrates a PLC control system to realize the coordinated control and parameter adjustment of each drive unit.

[0056] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0057] This utility model provides an adjustable welding robot. During use, the wires electrically connected to the control box 21 pass orderly through the movable sleeve 402 and are led out from the winding drum 403, tightly wound around the surface of the winding drum 403. The adjusting motor 7 drives the adjusting threaded rod 6 to rotate, moving the welding mechanism 17 to the appropriate welding position. During operation, the rotary motor 10 drives the mounting plate 9 to rotate uniformly in the horizontal direction. Simultaneously, the transmission motor 14 drives the transmission gear 13 to rotate continuously. Through the precision transmission of the switching gear disc 12, the welding structure can be flexibly rotated at multiple angles in the vertical direction. Afterwards, the robotic arm 16 can adjust the height of the welding mechanism according to the usage requirements, and complete the all-round angle conversion of the welding mechanism 17. During the frequent angle changes of the welding mechanism 17, the pulling force generated will cause the wire wrapped on the winding drum 403 to come off smoothly, ensuring that the wire has sufficient length to adapt to the movement of the mechanism. When the welding structure 17 completes the angle rotation, the winding drum 403 rotates synchronously under the elastic reset action of the internal torsion spring 404, and re-organizes and winds the excess wire that has loosened due to the movement of the mechanism back onto the surface of the winding drum 403, ensuring that the wire is always in an orderly state.

[0058] In summary, this adjustable welding robot, through the cooperation of the mounting base 1, the movable frame 2, the adjusting frame 3, and the winding frame 4, solves the problems mentioned in the background art.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
