[0033] like Figures 1 to 5 As shown, a welding device includes: a copper pressure seat 2, a connecting sleeve 3, several upper copper seats 4, a copper base 5 and several lower copper seats 6. The connecting sleeve 3 is threadedly connected to the copper pressure seat 2 and is coaxially arranged. A quick-release limiting structure 31 is provided on the connecting sleeve 3; one of the upper copper seats 4 is inserted into the connecting sleeve 3 and the upper end is connected to the copper pressure seat 2, and the quick-release limiting structure 31 can limit the upper copper seat 4; a connecting hole 51 is provided on the copper base 5; one of the lower copper seats 6 is partially inserted into the connecting hole 51.
[0034] In the present application, the connecting sleeve 3 is connected to the copper pressure seat 2 by a thread and the two are coaxially arranged. This connection method ensures the stability and concentricity of the connection and provides a basic support structure for the installation and operation of subsequent components. The upper copper seat 4 is inserted into the connecting sleeve 3, and its upper end is connected to the copper pressure seat 2, and the quick-release limit structure 31 on the connecting sleeve 3 plays a role in limiting the upper copper seat 4. When the upper copper seat 4 needs to be replaced, the quick-release limit structure 31 can quickly unlock or fix the upper copper seat 4, which is convenient for operation. A connecting hole 51 is provided on the copper base 5, and the lower copper seat 6 is partially inserted into the connecting hole 51. This plug-in connection method enables the lower copper seat 6 to be quickly connected and separated from the copper base 5.
[0035] For the upper copper seat 4, the quick-release limit structure 31 on the connecting sleeve 3 greatly improves the replacement efficiency. Compared with the traditional bolt thread connection method, there is no need to perform complicated bolt tightening operations, which saves replacement time and improves production efficiency. Especially when facing the situation where multiple products need to frequently replace upper copper seats 4 of different specifications, the advantages of this quick-release design are more obvious. The plug-in connection method of the copper base 5 and the lower copper seat 6 is simple and effective, and the upper copper seat 4 and the lower copper seat 6 can be replaced according to different products.
[0036] Furthermore, it also includes a driving member, which is connected to the copper pressure seat 2 and is used to drive the copper pressure seat 2 to move up and down. The driving member is a push rod motor.
[0037] Specifically, a socket 21 is provided on the copper socket 2 of the cylinder socket, and an inserting portion 41 is provided on the upper end of the upper copper socket 4. When the inserting portion 41 is inserted into the socket 21, the inserting portion 41 contacts the inner wall of the socket 21.
[0038] The socket 21 on the copper pressure seat 2 of the cylinder pressure seat cooperates with the insertion part 41 at the upper end of the upper copper seat 4. When the insertion part 41 is inserted into the socket 21, the contact between the two forms a tight connection relationship. This connection method increases the contact area between the upper copper seat 4 and the copper pressure seat 2 of the cylinder pressure seat, thereby improving the stability of the connection.
[0039] Specifically, the diameter of the inserting portion 41 is smaller than the diameter of the upper copper seat 4 , and the upper end surface of the upper copper seat 4 can abut against the lower end surface of the copper pressing seat 2 .
[0040] The design of the insertion portion 41 having a diameter smaller than that of the upper copper seat 4 enables the upper end surface of the upper copper seat 4 to more stably rest against the lower end surface of the copper pressure seat 2 when connected to the copper pressure seat 2, thereby increasing the stability of the upper copper seat 4.
[0041] Specifically, the quick-release limiting structure 31 includes a screw 311, a limiting block 312, and a handle 313. A slide 32 and a screw hole 33 are provided on the connecting sleeve 3. The screw hole 33 is connected to the slide 32. The limiting block 312 is slidably set in the slide 32. The screw 311 is threadedly connected to the screw hole 33 and is rotatably connected to the limiting block 312. The handle 313 is fixed on the screw 311; an annular limiting groove 42 is provided on the upper copper seat 4, and the limiting block 312 can be extended into the annular limiting groove 42 to limit the upper copper seat 4.
[0042] When it is necessary to limit the upper copper seat 4, the handle 313 is rotated to drive the screw rod 311 to rotate in the screw hole 33. Since the screw rod 311 is rotatably connected to the limit block 312, and the limit block 312 is slidably set in the slideway 32, the rotational movement of the screw rod 311 is converted into a linear sliding movement of the limit block 312 in the slideway 32. As the screw 311 rotates, the limit block 312 moves along the slideway 32 toward the upper copper seat 4 until the limit block 312 extends into the annular limit groove 42 opened on the upper copper seat 4. At this time, the limit block 312 plays a limiting role on the upper copper seat 4, limiting the axial movement of the upper copper seat 4, so that it maintains a stable position during work.
[0043] The quick-release limit structure 31 achieves limiting and unlocking the upper copper seat 4 by operating the handle 313, which is simple and convenient to operate. The operator only needs to rotate the handle 313 to complete the entire operation process, without the need for other complicated tools or tedious operating steps. This convenient operation method greatly improves work efficiency, especially when the upper copper seat 4 needs to be frequently replaced, which can save a lot of time and labor costs. Anyone can operate it after a simple check.
[0044] Specifically, a first guide bevel 421 is provided on the annular limit groove 42, and a second guide bevel 3121 and a support surface 3122 are provided on the limit block 312. The first guide bevel 421 corresponds to the second guide bevel 3121. After the limit block 312 is inserted into the annular limit groove 42, the support surface 3122 can abut against the upper wall of the annular limit groove 42 to limit the upper copper seat 4.
[0045] The first guide bevel 421 on the annular limit groove 42 corresponds to the second guide bevel 3121 on the limit block 312. During the process of inserting the limit block 312 into the annular limit groove 42, these two guide bevels play an important guiding role. When the upper copper seat 4 is installed, even if there is a certain deviation in the initial position, during the process of pushing the limit block 312 into the annular limit groove 42, the first guide bevel 421 and the second guide bevel 3121 will contact each other and guide the limit block 312 to be smoothly inserted into the annular limit groove 42.
[0046] When the limit block 312 is inserted into the annular limit groove 42, the support surface 3122 on the limit block 312 can rest against the upper wall of the annular limit groove 42. This limiting method enables the upper copper seat 4 to maintain a stable position during operation, ensuring the accuracy and stability of the welding work.
[0047] Specifically, at least one guide groove 511 arranged along the height direction and a surrounding groove 512 arranged at the bottom of the connecting hole 51 are provided on the inner wall of the connecting hole 51. The guide groove 511 is connected to the surrounding groove 512. A protrusion 61 corresponding to the guide groove 511 is provided on the lower copper seat 6 of the lower copper tube. The lower copper seat 6 can rotate relative to the copper base 5, and the protrusion 61 can enter the annular groove surrounding groove 512 to prevent the lower copper seat 6 from falling out of the connecting hole 51.
[0048] During installation, align the protrusion 61 on the lower copper seat 6 with the guide groove 511 on the inner wall of the connecting hole 51 of the copper base 5, and then insert the lower copper seat 6 into the connecting hole 51. As the lower copper seat 6 is inserted, the protrusion 61 moves downward along the guide groove 511. When the protrusion 61 moves to the bottom of the guide groove 511, the lower copper seat 6 is rotated so that the protrusion 61 enters the surrounding groove 512. At this time, the protrusion 61 is located in the surrounding groove 512. Since the surrounding groove 512 is located at the bottom of the connecting hole 51, the upward movement of the lower copper seat 6 is restricted, preventing the lower copper seat 6 from falling out of the connecting hole 51.
[0049] The design of the guide groove 511 provides a clear insertion path and direction guidance for the installation of the lower copper seat 6. When installing the lower copper seat 6, the operator only needs to align the protrusion 61 with the guide groove 511 and insert it without the need for complicated alignment and adjustment operations, which greatly improves the convenience and efficiency of installation.
