Description

Technical Field

[0001] This application relates to the technical field of welding heads, and in particular to a flexible floating welding head. Background Technology

[0002] Traditional metal welding processes involve pre-assembling two metal parts, then placing the two pre-assembled metal parts under a welding machine and welding them together by releasing a high-voltage current.

[0003] During the welding process, the welding head needs to apply a downward force to the metal part. If it is a rigid welding base, the weld joint of the metal part will be affected by this force and cause a dent, affecting the surface structure. Therefore, further improvement is needed. Utility Model Content

[0004] To address the above problems, this application provides a flexible floating welding head.

[0005] This application provides a flexible floating welding head, which adopts the following technical solution:

[0006] A flexible floating welding head includes a welding head and a welding seat coaxially arranged with the welding head. The welding seat includes a welding seat cylinder and a support member disposed on the upper surface of the welding seat cylinder. An elastic member is built into the welding seat cylinder, and the support member abuts against the elastic member. The support member can move up and down along the height direction of the welding seat cylinder.

[0007] By adopting the above technical solution, the elastic element is set to buffer the support when it is subjected to impact. During the welding process, the welding seat can elastically float according to the actual stress of the metal part, which effectively reduces the problem of dents at the weld joint caused by hard contact, thereby ensuring the surface structure integrity of the welded part.

[0008] Preferably, the elastic element includes a spring, and a first mounting groove for installing the spring is provided inside the welding base cylinder. The two ends of the spring abut against the inner bottom wall of the first mounting groove and the lower end of the support member, respectively. The elastic element is detachably connected to the welding base cylinder.

[0009] By adopting the above technical solution, the elastic properties of the spring are used to enable the support to float within the welding base cylinder. This effectively buffers the downward pressure exerted by the welding head on the metal part during welding, reducing the possibility of dents at the weld joint due to rigid contact and improving the surface quality of the welded part. Furthermore, the spring's contact and detachable design allows for the replacement of springs of different specifications according to welding requirements during use, and also facilitates replacement when the spring deforms.

[0010] Preferably, the elastic element further includes an elastic pad disposed between the spring and the support.

[0011] By adopting the above technical solution and by setting an elastic pad, the wear problem caused by rigid contact between the support and the spring can be reduced.

[0012] Preferably, the elastic element is an elastic airbag, and the elastic airbag is filled with gas.

[0013] By adopting the above technical solution, compared with springs, airbags have a larger elastic deformation range and more uniform force transmission characteristics. They can not only achieve the same function as springs, namely absorbing excess pressure, but also adjust the inflation volume of airbags according to actual needs, thereby changing their elastic properties to adapt to the welding requirements of different types of metal parts.

[0014] Preferably, the welding base cylinder includes a first cylinder and a second cylinder disposed on the first cylinder, the elastic element is built into the first cylinder, the support element is slidably inserted into the second cylinder, and the second cylinder is detachably connected to the first cylinder.

[0015] By adopting the above technical solution, the welding base cylinder is divided into a first cylinder and a second cylinder, with the elastic element built into the first cylinder, making the installation of the elastic element more stable and facilitating maintenance and replacement. The support component is slidably inserted into the second cylinder, allowing it to float during welding, thereby effectively reducing the impact of downward force on the surface structure of the metal part during welding and reducing denting problems. Furthermore, the second cylinder is detachably connected to the first cylinder, facilitating the replacement of different specifications of the second cylinder according to actual welding needs, improving the applicability and flexibility of the welding joint.

[0016] Preferably, the second cylinder has a protruding sleeve, the sleeve has an external thread, and the inner wall of the first cylinder has an internal thread.

[0017] By adopting the above technical solution, the first cylinder and the second cylinder are detachably connected via a sleeve and internal thread. This design allows the second cylinder to be easily installed and replaced, thus adapting to the needs of different specifications of support components or welding heads, and improving the overall applicability of the welding head. At the same time, the threaded connection method is simple to operate, reliable, and easy to maintain and adjust.

[0018] Preferably, a limiting member is provided between the first cylinder and the second cylinder, the limiting member being used to restrict the rotation of the second cylinder.

[0019] By adopting the above technical solution, the rotation of the second cylinder can be effectively restricted by setting a limiting component, thereby ensuring a stable connection between the first and second cylinders during assembly, reducing the adverse effects caused by component loosening during welding, and ensuring the stability of welding quality.

[0020] Preferably, the limiting member includes a limiting bolt passing through the first cylinder, and the limiting bolt is threadedly connected to the sleeve.

[0021] By adopting the above technical solution and using a limit bolt connected to the sleeve thread, relative rotation between the first and second cylinders can be effectively prevented, thereby ensuring the stable lifting and lowering of the support component within the welding base cylinder. This design not only improves the stability of the welding head during welding but also reduces the problem of decreased welding accuracy caused by component loosening.

[0022] Preferably, the limiting member includes a limiting rod passing through the first cylinder, a limiting spring coaxially sleeved on the limiting rod, and a toggle block disposed on the limiting rod. A limiting plate is coaxially sleeved on the limiting rod, and the limiting spring is disposed between the limiting plate and the toggle block. A slot for the toggle block to be engaged is opened on the outer surface of the first cylinder, and a limiting hole for the limiting rod to be inserted is opened on the sleeve. The limiting spring forces the limiting rod to move toward the limiting hole.

[0023] By adopting the above technical solution, the cooperation between the limiting rod and the limiting hole can effectively limit the relative rotation between the first cylinder and the second cylinder, ensure the stability of the welding head during the welding process, and reduce the possibility of decreased welding accuracy due to loose parts.

[0024] In summary, this utility model has the following beneficial effects:

[0025] 1. By setting a welding socket containing elastic elements, the pressure applied by the welding head to the metal part can be effectively buffered, reducing the possibility of dents in the metal part due to uneven stress during the welding process, thereby improving the surface quality and structural integrity of the product.

[0026] 2. By setting limiters, the possibility of relative rotation between the first cylinder and the second cylinder during use is reduced, thereby improving the connection strength between the first cylinder and the second cylinder. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail below.

[0036] This application discloses an elastic floating welding head.

[0037] Example:

[0038] A flexible floating welding head, as shown in the reference Figure 1 , Figure 2 The welding device includes a welding head 1 and a welding base 2 coaxially arranged with the welding head 1. The welding base 2 includes a cylindrical welding base 2 and a support member 4 disposed on the upper surface of the cylindrical welding base 2. An elastic member 5 is built into the cylindrical welding base 2, and the support member 4 abuts against the elastic member 5. The support member 4 can move up and down along the height direction of the cylindrical welding base 2. The elastic member 5 realizes a flexible connection between the welding head 1 and the welding base 2, thereby reducing the possibility of surface depression caused by uneven stress on the metal parts during the welding process.

[0039] Specifically, in this embodiment, the welding base 2 cylinder includes a first cylinder 31 and a second cylinder 32 disposed on the first cylinder 31, the second cylinder 32 being detachably connected to the first cylinder 31. The upper end face of the first cylinder 31 has a first mounting groove 311, and the lower end face of the second cylinder 32 has a second mounting groove 321. The first mounting groove 311 and the second mounting groove 321 are interconnected. In this embodiment, the elastic element 5 is a spring 51, which is built into the first mounting groove 311. The support element 4 is slidably inserted into the second cylinder 32. The support element 4 specifically includes a base 41 built into the second mounting groove 321 and a support head 42 disposed on the base 41. The upper end of the support head 42 slides through the upper end face of the second cylinder 32, corresponding to the welding head 1. The two ends of the spring 51 abut against the inner bottom wall of the first mounting groove 311 and the lower end face of the base 41, respectively.

[0040] In this embodiment, the second cylinder 32 has a protruding sleeve 33, and the sleeve 33 has an external thread 331. The inner wall of the first cylinder 31 has an internal thread 312. The threaded connection between the external thread 331 and the internal thread 312 allows the first cylinder 31 to be detached from the second cylinder 32.

[0041] The implementation principle of an elastic floating welding head in this application embodiment is as follows: the elastic element 5 is provided to buffer the support 4 when it is subjected to impact. During the welding process, the welding seat 2 can generate elastic floating according to the actual stress of the metal part, effectively reducing the problem of denting at the weld joint caused by hard contact, thereby ensuring the surface structure integrity of the welded part.

The surface of the elastic pad 52 away from the spring 51 may have a roughened layer to reduce the possibility of relative rotation of the elastic element 5 during use. It should be noted that an elastic pad 52 may also be disposed between the inner bottom wall of the spring 51 and the second mounting groove 321 to reduce wear problems caused by rigid contact between the two ends of the spring 51 and the first cylinder 31 and the base 41.

[0044] Example 3:

[0045] Reference Figure 4The difference from Embodiment 1 is that in this embodiment, the elastic element 5 is an elastic airbag 53. The elastic airbag 53 can be a sealed cavity made of rubber, filled with compressed air or inert gas. Compared with the spring 51, the elastic airbag 53 has a larger elastic deformation range and more uniform force transmission characteristics. It can also reduce the wear problem caused by rigid contact between the two ends of the spring 51 and the first cylinder 31 and the base 41.

[0046] Example 4:

[0047] The difference from Embodiment 1 is that a limiting member 6 is provided on both the first cylinder 31 and the second cylinder 32. The limiting member 6 is used to restrict the rotation of the second cylinder 32. In this embodiment, the limiting member 6 may be a sealing ring (not shown in the figure) coaxially sleeved on the sleeve 33, or as... Figure 5 As shown, the limiting member 6 is a limiting bolt 61 that passes through the first cylinder 31, and the sleeve 33 has a threaded hole for threaded connection of the limiting bolt 61.

[0048] Example 5:

[0049] Reference Figure 6 , Figure 7 The difference from Embodiment 4 is that the limiting member 6 includes a limiting rod 62 passing through the first cylinder 31, a limiting spring 63 coaxially sleeved on the limiting rod 62, and a toggle block 64 disposed on the limiting rod 62. The first cylinder 31 has a through groove 313 for the limiting rod 62 to pass through, and a third mounting groove 314 for the limiting spring 63 to be installed is provided in the through groove 313 of the first cylinder 31. The outer peripheral wall of the limiting rod 62 is coaxially sleeved with a limiting spring 63. Position plate 621, limit spring 63 is disposed between limit plate 621 and toggle block 64, the two ends of limit spring 63 are respectively connected to the end faces of limit plate 621 and third mounting groove 314 that are close to each other, the outer surface of first cylinder 31 is provided with a slot 315 for toggle block 64 to be inserted, and the sleeve 33 is provided with a limit hole 332 for limit rod 62 to be inserted, the limit spring 63 forces limit rod 62 to move toward the direction close to limit hole 332.
