Description

Technical Field

[0001] The utility model relates to the technical field of welding tools, in particular to a micro-vibration device for metal welding. Background Technique

[0002] A metal welding device is a special equipment used to realize the connection between metals. Its working principle is mainly to use means such as high temperature, pressure or vibration to cause the combination between atoms or molecules of metals, so as to achieve a firm connection. For example, a metal welding device with the publication number of CN117102769A specifically discloses including a welding machine, a welding clamp, a push-pull swing rod, a magnetic support, and a hinge support. The magnetic support is hinged to the hinge support. The hinge support is slidably connected to the push-pull swing rod along the axial direction of the push-pull swing rod. The hinge support is hinged to the magnetic support. The magnetic support has magnetism and is used to adsorb and fix on the surface of the metal workpiece. The front end of the push-pull swing rod is connected to the welding core of the welding rod, and the rear end of the push-pull swing rod is connected to the welding clamp or a wire. The push-pull swing rod and the magnetic support are insulated. The push-pull swing rod is made of a metal material. During use, there is no need to walk back and forth, shortening the walking route during the welding process, improving work efficiency, reducing work intensity, increasing the distance between the staff and the welding position, reducing the harm caused by fumes, heat, and radiation light to the staff, and being able to weld the inside of the box outside the box. Since there are usually oxides and other impurities on the metal surface, these substances will hinder the direct contact and fusion between metals, resulting in a reduction in the welding effect and connection quality. Therefore, we propose a micro-vibration device for metal welding. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides the following technical solutions:

When the convex part is separated from the impact member, the elastic force of the spring drives the impact member to move and impact on the outside of the platform, so that the platform and the workpiece thereon generate high-frequency vibration.

[0013] Utilizing high-frequency and small-amplitude mechanical vibration, the vibration will also cause tiny vibration and displacement on the metal surface. When two metal parts are clamped together, this kind of tiny vibration and displacement can effectively apply pressure and friction force to the welded joint, break the oxide layer on the metal surface, and make the metal surfaces directly contact. High-frequency and small-amplitude mechanical vibration can help remove these oxides and impurities, make the metal surface cleaner, and is beneficial to the formation of the welded joint.

[0014] Through high-frequency and small-amplitude vibrations, the two metal surfaces to be welded will continuously rub against and collide with each other, which will increase the contact area between them. A larger contact area means more atomic bonding points, thereby improving the strength and reliability of the welded joint. Brief Description of the Drawings

Detailed Embodiment

[0022] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0023] Embodiment: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, a micro-vibration device for metal welding of the present utility model includes a machine base 1. A platform 2 is provided at the upper end of the machine base 1. The platform 2 is rotatably installed on the machine base 1. A plurality of clamping mechanisms distributed in a circumferential array are provided on the platform 2. A groove body 3 is fixedly installed at the center of the top of the platform 2. A driving mechanism is installed on the machine base 1. The driving mechanism is connected to the platform 2 and can drive the platform 2 to rotate. A plurality of convex parts 7 are fixedly installed on the outside of the platform 2. A plurality of slots 8 distributed in a circumferential array are fixedly installed on the machine base 1. An insertion plate 9 is inserted into the slot 8. A sliding sleeve 10 is fixedly installed on the insertion plate 9. A slidable impact member 11 is inserted into the sliding sleeve 10. A spring 12 is fixedly connected inside the sliding sleeve 10. One end of the spring 12 is fixedly connected to the impact member 11. The impact member 11 can contact the convex part 7.

[0024] An air pump 4 is fixedly installed on the machine base 1. The air inlet end of the air pump 4 is communicated and fixedly installed with a connecting pipe 5. The connecting pipe 5 is communicated with the groove body 3 and is rotatably installed on the platform 2. A valve 6 is installed on the connecting pipe 5. The clamping mechanism includes a vertical plate 13. The vertical plate 13 is fixedly connected to the platform 2. A clamping plate 14 is provided on one side of the vertical plate 13. Two guide rods 15 arranged at intervals are fixedly connected to the clamping plate 14. The guide rods 15 penetrate through the vertical plate 13. An elastic member 16 is fixedly connected to the clamping plate 14. The other end of the elastic member 16 is fixedly connected to the vertical plate 13.

[0025] Among them, the driving mechanism includes a gear ring 18. The gear ring 18 is fixedly connected to the bottom of the platform 2. A motor 19 is fixedly installed on the machine base 1. A driving wheel 20 is fixedly installed at the output shaft end of the motor 19. The driving wheel 20 meshes with the gear ring 18. By placing the workpiece on the groove body 3, the motor 19 drives the driving wheel 20 to rotate. The driving wheel 20 drives the gear ring 18 to rotate. The gear ring 18 and the platform 2 rotate synchronously. The convex part 7 on the platform 2 rotates and contacts the impact member 11. The impact member 11 is squeezed by the convex part 7 and the spring 12 contracts. When the convex part 7 is separated from the impact member 11, the elastic force of the spring 12 drives the impact member 11 to move and impact on the outside of the platform 2, so that the platform 2 and the workpiece thereon generate high-frequency vibration.

[0026] The workpiece is clamped by a plurality of clamping plates 14. The elastic force of the elastic member 16 drives the clamping plate 14 to press on the outside of the workpiece, which can fix the workpiece. Cooperating with the air pump 4 to suck the air in the groove body 3, the inside of the groove body 3 is in a negative pressure state. A plurality of strip-shaped grooves are opened on the groove body 3. The workpiece can be adsorbed on the groove body 3, so as to further fix the workpiece, improve the firmness of the workpiece, and avoid the dislocation and movement of the workpiece.

[0027] Among them, an electromagnet 17 is fixedly installed on the insertion plate 9. The impact member 11 is a magnet. The electromagnet 17 is energized and can generate a repulsive force on the impact member 11. By generating a repulsive force on the impact member 11 by the electromagnet 17, when the impact member 11 impacts on the outside of the platform 2, the repulsive force can increase the magnitude of the impact force, thereby increasing the vibration amplitude.

[0028] Among them, a plurality of conduction ports 21 distributed in a circumferential array are formed on the platform 2. An annular pipeline 22 is fixedly installed on the machine base 1. A plurality of exhaust pipes 23 are connected and fixedly installed at the top of the annular pipeline 22. The exhaust pipes 23 are arranged towards the conduction ports 21. A fan 24 is fixedly installed on the machine base 1. The exhaust end of the fan 24 is communicated with the annular pipeline 22. The low-temperature air is introduced into the annular pipeline 22 by the fan 24, and then discharged by the plurality of exhaust pipes 23 and discharged to the conduction ports 21, so as to rapidly cool the workpiece at the groove body 3 after welding is completed.

[0029] The working principle mainly utilizes high-frequency and small-amplitude mechanical vibrations. When heated to a certain temperature, the micro-topography on the metal surface comes into contact to form a weld. Specifically, when the ultrasonic vibration energy is transmitted to the metal surface, due to the conductivity of the metal structure and the internal impedance of the material, the energy will be converted into heat energy, causing local heating of the metal surface. The vibration will also cause small vibrations and displacements on the metal surface. When two metal parts are clamped together, these small vibrations and displacements can effectively apply pressure and friction to the welding joint, breaking the oxide layer on the metal surface and making the metal surfaces directly contact. The high-frequency and small-amplitude mechanical vibrations can help remove these oxides and impurities, making the metal surface cleaner and facilitating the formation of the welding joint. Through the high-frequency and small-amplitude vibrations, the two metal surfaces to be welded will continuously rub and collide with each other, which will increase the contact area between them. A larger contact area means more atomic bonding points, thus improving the strength and reliability of the welding joint.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
