Description

Technical Field

[0001] This utility model relates to the field of welding wire guiding technology, specifically a welding wire guiding device. Background Technology

[0002] Welding wire is a type of metal wire used as filler metal or as the material being welded during the welding process. It is a key consumable material in processes such as electric arc welding and gas welding. During welding, it is continuously fed into the arc zone through a welding torch, melts at high temperature, and fuses with the base material (the workpiece being welded). After cooling, it forms a strong weld, connecting the workpieces together.

[0003] In the prior art, the authorized announcement number CN213888771U discloses a welding wire guiding device, which relates to the field of welding wire processing equipment technology. It includes a rotating base, and on one side of the rotating base along the width direction, there are mounting plates symmetrically swinging. A swing shaft is vertically fixed on the adjacent side wall of the two mounting plates. The swing shaft is rotatably engaged with the rotating base. Gears are coaxially fixed at the lower ends of the two swing shafts. A sliding groove is opened in the middle of the rotating base along the length direction of the rotating base.

[0004] During welding, the required wire diameter and feed speed vary significantly depending on the welding location. To ensure welding quality and production efficiency, operators need to precisely select a suitable wire diameter based on the welding material, workpiece thickness, joint type, and specific welding position, and feed the wire stably and accurately to the welding position at an appropriate speed matching that diameter. Therefore, a wire guiding device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a welding wire guiding device to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding wire guiding device, comprising a base, a wire inlet fixedly installed at one end of the base, a wire outlet fixedly installed at the other end of the base, a protective cover plate fixedly installed on one side of the base, a driving assembly installed on the base, the driving assembly comprising a motor fixedly installed on the base and a drive shaft rotatably installed inside the base, a worm gear fixedly installed on the drive shaft, a drive wheel fixedly installed at the end of the drive shaft, a worm fixedly installed at the output end of the motor, and a clamping assembly installed inside the base.

[0007] Preferably, the motor is provided with a control line interface, and the base is provided with a through hole, through which the output end of the motor extends into the base.

[0008] Preferably, a bearing is mounted on the base, and the drive shaft is rotatably mounted on the base via the bearing.

[0009] Preferably, the worm wheel and the drive wheel are both rotatably mounted in the base via a drive shaft, and the worm is rotatably mounted in the base via a motor, with the worm wheel and the worm meshing together.

[0010] Preferably, the clamping assembly includes a positioning frame fixedly installed in the base and a positioning shaft rotatably installed in the base. A clamping arm is rotatably installed on the positioning shaft, a pressure roller is rotatably installed on the clamping arm, a threaded cylinder is rotatably installed on the positioning frame, an adjusting screw is threadedly installed on the threaded cylinder, and a knob is fixedly installed at the lower end of the adjusting screw.

[0011] Preferably, the clamping arm has a rotating hole, and the clamping arm is rotatably mounted on the positioning shaft through the rotating hole.

[0012] Preferably, the threaded cylinder is provided with a rotating shaft, and the threaded cylinder is rotatably mounted on the positioning frame via the rotating shaft.

[0013] Preferably, the threaded cylinder is rotatably mounted in the base via a positioning frame, the clamping arm is provided with a bearing, the pressure roller is rotatably mounted on the clamping arm via the bearing, and the clamping arm is rotatably mounted in the base via a positioning shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this application, after the motor is started, the motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the drive shaft to rotate, which in turn drives the drive wheel to rotate. The drive wheel's rotation causes the welding wire to move forward, thereby achieving the feeding of the welding wire. Furthermore, the feeding speed of the welding wire can be adjusted by changing the motor's speed.

[0015] 2. In this application, after the welding wire passes through the inlet and outlet, it can be moved upward by rotating the adjusting screw. During the upward movement of the adjusting screw, the clamping arm rotates around the positioning shaft, causing the pressure roller on the clamping arm to move closer to the drive wheel. In this way, the drive wheel and the pressure roller can clamp welding wires of different diameters, thereby guiding welding wires of different diameters to the welding position.

Detailed Implementation

[0018] 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.

[0019] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a welding wire guiding device, including a base 1, a wire inlet 2 fixedly installed at one end of the base 1, a wire outlet 3 fixedly installed at the other end of the base 1, a protective cover plate 4 fixedly installed on one side of the base 1, a driving assembly 5 installed on the base 1, and a clamping assembly 6 installed inside the base 1. Through the coordinated cooperation between the driving assembly 5 and the clamping assembly 6, the system can precisely control the feeding process of the welding wire, ensuring that welding wires of various diameters are stably and continuously fed to the welding position at a stable and appropriate rate, thereby ensuring the stability of the welding process and the reliability of the weld quality.

[0020] Example 1: As Figure 2 and Figure 3 As shown, the drive assembly 5 includes a motor 501 fixedly mounted on the base 1 and a drive shaft 505 rotatably mounted inside the base 1. A worm gear 504 is fixedly mounted on the drive shaft 505, and a drive wheel 506 is fixedly mounted at the end of the drive shaft 505. A worm 502 is fixedly mounted at the output end of the motor 501. The motor 501 is provided with a control line interface 503. A through hole is opened on the base 1, and the output end of the motor 501 extends into the base 1 through the through hole. A bearing is installed on the base 1, and the drive shaft 505 is rotatably mounted on the base 1 through the bearing.

[0021] Specifically, after starting motor 501, it begins to work and outputs rotational power, thereby driving the worm gear 502 connected to it to rotate. The rotation of worm gear 502 is further transmitted to worm wheel 504 through gear meshing, causing worm wheel 504 to also begin to rotate. The rotation of worm wheel 504, through its connection with drive shaft 505, drives drive shaft 505 to rotate as well. The rotational motion of drive shaft 505 is transmitted to drive wheel 506, causing drive wheel 506 to rotate as well, which in turn propels the welding wire forward by friction, achieving a stable welding wire feeding process. In addition, by adjusting the input speed of motor 501, the output speed of the entire transmission system can be accurately controlled, thereby flexibly adjusting the welding wire feeding speed to meet the needs of different welding processes.

[0022] Example 2: Figure 2 and Figure 4 As shown, the clamping assembly 6 includes a positioning frame 601 fixedly installed in the base 1 and a positioning shaft 607 rotatably installed in the base 1. A clamping arm 605 is rotatably installed on the positioning shaft 607, and a pressure roller 606 is rotatably installed on the clamping arm 605. A threaded cylinder 602 is rotatably installed on the positioning frame 601. An adjusting screw 603 is threaded on the threaded cylinder 602. A knob 604 is fixedly installed at the lower end of the adjusting screw 603. A rotating hole is provided on the clamping arm 605, and the clamping arm 605 is rotatably installed on the positioning shaft 607 through the rotating hole. A rotating shaft is provided on the threaded cylinder 602, and the threaded cylinder 602 is rotatably installed on the positioning frame 601 through the rotating shaft.

[0023] Specifically, the welding wire is introduced into the mechanism through the wire inlet 2 and passes smoothly through the wire outlet 3. The operator can then move it upwards by rotating the adjusting screw 603. As the adjusting screw 603 moves upwards, the clamping arm 605 rotates around the positioning shaft 607, causing the pressure roller 606 mounted on the clamping arm 605 to gradually approach the drive wheel 506. Through this mechanical linkage, an effective clamping action is formed between the drive wheel 506 and the pressure roller 606, thus firmly clamping welding wires of different diameters. Ultimately, this mechanism can reliably and accurately guide various types of welding wires to the welding position, ensuring the continuity and stability of the welding process.

[0024] Example 3: Figure 5 As shown, this device is a horizontal wire guide. Compared to the vertical wire guide, its wire inlet 2 and wire outlet 3 are arranged vertically. The horizontal wire guide is also equipped with a drive assembly 5 and a clamping assembly 6, whose functions are the same as those of the drive assembly 5 and clamping assembly 6 on the vertical wire guide. The horizontal wire guide guides the welding wire to move horizontally, while the vertical wire guide guides the welding wire to move vertically.

[0025] Working principle: First, the welding wire must be introduced through the inlet 2 and led out through the outlet 3. Once the welding wire has completely passed through these two ports, the adjusting screw 603 can be rotated to move it smoothly upwards. As the adjusting screw 603 moves upwards, it drives the clamping arm 605 to rotate around the positioning shaft 607 as a fulcrum. This rotation causes the pressure roller 606 mounted on the clamping arm 605 to gradually move closer to the drive wheel 506, thus clamping welding wires of different diameters between the drive wheel 506 and the pressure roller 606, guiding welding wires of different diameters to the welding area. After the drive wheel 506 clamps the welding wire with the pressure wheel 606, the motor 501 can be started. Starting the motor 501 will drive the worm gear 502 to rotate, which in turn drives the worm wheel 504 to rotate. The worm wheel 504, in turn, drives the drive shaft 505 to rotate, which in turn drives the drive wheel 506 to rotate. When the drive wheel 506 starts rotating, it uses friction with the welding wire to continuously and stably feed the wire forward, thus achieving an effective wire feeding process. Simultaneously, by adjusting the speed of the motor 501, the rotational speed of the drive wheel 506 can be precisely controlled, thereby flexibly adjusting the wire feeding rate to meet the specific requirements of different welding processes for wire feeding speed.
