Description

Technical Field

[0001] The utility model relates to the technical field of automatic welding machines, in particular to a wire feeding mechanism of an automatic welding machine. Background Art

[0002] Automatic welding machines utilize automation technology to automate the welding process, including automatic loading, cutting, and stripping, as well as automatic loading and robotic handling of upper and lower covers. This significantly improves production efficiency and welding quality. Suitable for mass production and automated production environments, these machines are fast, clean, and efficient, significantly reducing production costs and improving productivity.

[0003] During the use of the automatic welding machine, the welding wire needs to be automatically conveyed by the wire feeding mechanism. In the existing technology, most automatic wire feeding mechanisms generally clamp the welding wire through two rollers, and then convey the welding wire forward by friction. At the same time, a spring is used to adjust the position between the two rollers. However, the position of the spring is relatively fixed, and the welding wire may be flattened during the friction with the welding wire, resulting in the inability to convey the welding wire forward. The practicality is insufficient. Therefore, it is necessary to redesign a wire feeding mechanism for the automatic welding machine to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a wire feeding mechanism for an automatic welding machine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure is that second end of sliding panel withstands on the back of interlocking structure and is fixed with a toothed structure, and the bottom of interlocking structure is fixed with a toothed structure.

[0007] Preferably, the support mechanism is fixedly mounted on a support plate on the upper end surface of the base plate, and the electric push rod is fixedly mounted on an inner wall of the support plate.

[0008] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the moving frame, and the limiting rod slides through the moving plate.

[0009] Preferably, the connection mechanism includes two connection rods that are slidably installed through the outer wall of the movable frame, and the two ends of the two connection rods are fixedly connected to the movable plate and the outer wall of the connection plate respectively.

[0010] Preferably, a connecting plate is fixedly installed on the telescopic end of the electric push rod, and sponge pads are fixedly installed on the inner wall of the connecting plate and the fixed plate.

[0011] Preferably, anti-slip sleeves are fixedly mounted on the outer walls of the active roller and the driven roller, and both anti-slip sleeves are made of rubber.

[0012] Beneficial effects of the utility model:

[0013] 1. By setting up components such as an adjusting rod, a limit rod and an adjusting spring, the adjusting rod can slide on the outer wall of the connecting plate and drive the limit plate to pull the adjusting spring. Through the elastic action of the adjusting spring, the clamping force of the driven roller can be elastically adjusted. While not affecting the clamping effect, it can also avoid excessive clamping force that may cause deformation of the welding wire.

[0014] 2. By setting up components such as an electric push rod, a connecting plate and a sponge pad, the electric push rod can drive the connecting plate to move, thereby allowing the two sponge pads to approach each other, so that the oil and dust on the outer wall of the welding wire can be cleaned during the wire feeding process, thereby removing impurities on the surface of the welding wire and ensuring welding quality.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-7 , a wire feeding mechanism of an automatic welding machine, including a base plate 1, a fixed plate 2 is fixedly installed on the upper end surface of the base plate 1, an electric push rod 4 is fixedly installed on the upper end surface of the base plate 1 through a supporting mechanism, the supporting mechanism is fixedly installed on the support plate 3 on the upper end surface of the base plate 1, the electric push rod 4 is fixedly installed on the inner wall of the support plate 3, the telescopic end of the electric push rod 4 is fixedly installed with a connecting plate 5, the connecting plate 5 and the inner wall of the fixed plate 2 are fixedly installed with a sponge pad 6, an active roller 7 is rotatably installed on the upper end surface of the base plate 1, and a sponge pad 6 is fixedly installed on the bottom wall of the base plate 1. The first motor 8 is connected to the active roller 7, and the upper end surface of the bottom plate 1 is rotatably installed with a screw 10 through a movable frame 9. The outer wall of the movable frame 9 is fixedly installed with a second motor 11 connected to the screw 10. The outer wall of the screw 10 is threadably installed with a movable plate 13 through a limiting mechanism. The limiting mechanism includes a limiting rod 12 fixedly installed inside the movable frame 9. The limiting rod 12 slides through the movable plate 13. The limiting rod 12 can limit the movable plate 13 so that the movable plate 13 can only move axially along the outer wall of the screw 10.

[0025] The outer wall of the movable plate 13 is fixedly connected to the connecting plate 15 through a connecting mechanism. The connecting mechanism includes two connecting rods 14 that are slidably installed on the outer wall of the movable frame 9. The two ends of the two connecting rods 14 are fixedly connected to the outer walls of the movable plate 13 and the connecting plate 15 respectively. Two adjusting rods 16 are slidably installed on the outer wall of the connecting plate 15. The outer walls of the two adjusting rods 16 are fixedly installed with limit plates 17. Adjustment springs 18 are installed on the outer walls of the two adjusting rods 16. The two ends of the two adjusting springs 18 are elastically connected to the outer wall of the connecting plate 15 and the inner wall of the limit plate 17 respectively. The ends of the two adjusting rods 16 are jointly fixedly connected to a connecting frame 19. A driven roller 20 is rotatably installed inside the connecting frame 19. The outer walls of the active roller 7 and the driven roller 20 are fixedly installed with anti-slip sleeves 21. The two anti-slip sleeves 21 are made of rubber.

[0026] When the present invention is used, the welding wire can be placed between the fixed plate 2 and the connecting plate 5, and then the welding wire can be pulled between the active roller 7 and the driven roller 20. Then the second motor 11 can drive the screw 10 to rotate. When the screw 10 rotates, it can drive the movable plate 13 to move by cooperating with the limit rod 12. At this time, the movable plate 13 can drive the connecting plate 15 to move by cooperating with the two connecting rods 14. As a result, the connecting plate 15 can drive the connecting frame 19 to move through the cooperation of the two adjusting rods 16. In this process, the connecting frame 19 can drive the driven roller 20 to move and approach the active roller 7, so that the active roller 7 and the driven roller 20 can clamp the welding wire through the cooperation of the anti-slip sleeve 21.

[0027] At the same time, in the process of clamping the welding wire, the adjusting rod 16 can slide on the outer wall of the connecting plate 15 and drive the limit plate 17 to pull the adjusting spring 18. By adjusting the elastic action of the spring 18, the clamping force of the driven roller 20 can be elastically adjusted. Without affecting the clamping effect, it can also avoid the clamping force being too large to cause deformation of the welding wire. Then the first motor 8 can drive the active roller 7 to rotate, thereby clamping and feeding the welding wire through the cooperation of the driven roller 20 and the anti-slip sleeve 21, and in the process of wire feeding, the electric push rod 4 can drive the connecting plate 5 to move, thereby making the two sponge pads 6 close to each other, so that the oil and dust on the outer wall of the welding wire can be cleaned during the wire feeding process to remove impurities on the surface of the welding wire and ensure the welding quality.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
