[0026] In existing technologies, welding semiconductor gas channels inevitably introduces small errors, affecting subsequent use. To mitigate these errors, it is typically necessary to manually estimate the approximate angle, fix it, and then make precise adjustments. However, manual adjustments result in significant errors and cannot guarantee the accuracy of the angle.

[0027] To solve the above problems, this utility model provides a welding angle adjustment device, such as... Figure 1 and Figure 2 As shown, it includes a base 1, a rotating chassis 2, an angle adjusting rod 6, and a support frame 9; the rotating chassis 2 and the support frame 9 are both mounted on the base 1; one end of the angle adjusting rod 6 is mounted on the rotating chassis 2, and the other end of the angle adjusting rod 6 is connected to the welded pipe fitting 8 through the connecting structure 7; the support frame 9 is provided with a placement groove 13, which is used to place the welded pipe fitting 8.

[0028] In this embodiment, the base 1 is used to support the overall structure and play a role in stabilizing the structure.

[0029] Specifically, in this embodiment, both the rotating chassis 2 and the support frame 9 are fixedly mounted on the base 1. The support frame 9 is detachably fixed to the base 1. A placement groove 13 is provided on the support frame 9, and the welding pipe 8 is placed in the placement groove 13. The placement groove 13 supports the pipe to be welded, and the angle adjustment rod 6 drives the welding pipe 8 to rotate, thereby creating a twisting effect on the pipe and achieving the purpose of adjusting the angle of the pipe.

[0030] More specifically, in this embodiment, the support frame 9 is provided with a snap-fit ​​groove 15, which can cooperate with the snap-fit ​​strip 14 on the base 1 to realize the snap-fit ​​connection between the support frame 9 and the base 1, such as... Figure 2 and Figure 3 As shown.

[0031] It is understood that in this embodiment, the support frame 9 and the base 1 are connected by a snap-fit, but it is not limited to snap-fit. It can also be other types of connection, such as bolt fixing connection, welding, etc., as long as it can achieve the goal of fixing the support frame 9 on the base 1 and ensuring the connection stability between the support frame 9 and the base 1.

[0032] In this embodiment, the rotating base 2 is fixedly mounted on the base 1 by a snap-fit ​​connection, and the angle adjustment rod 6 is rotatably mounted on the rotating base 2, while the rotating base 2 remains stationary; or the angle adjustment rod 6 is fixedly mounted on the rotating base 2 and can rotate on its own under the action of the rotating base 2. A connecting structure 7 is provided at the upper end of the angle adjustment rod 6 or at another corresponding position, which can be used to connect the welded pipe fitting 8.

[0033] In this embodiment, the connecting structure 7 on the angle adjusting rod 6 is a mounting groove. One end of the welded pipe 8 is inserted into the mounting groove, so that the rotation of the angle adjusting rod 6 drives the welded pipe 8 to twist, thereby adjusting the welding angle of the welded pipe 8.

[0034] In this embodiment, the connecting structure 7 on the angle adjusting rod 6 can also be a clamp, a set screw, or other structure, thereby achieving a fixed connection between the angle adjusting rod 6 and the welding pipe 8, and thus achieving the purpose of adjusting the welding angle of the welding pipe 8.

[0035] In this embodiment, the placement groove 13 on the support frame 9 is set as a rectangular groove, which can better position the welded pipe 8.

[0036] In use, after the welded pipe fitting 8 passes through the placement groove 13 on the support frame 9, its end is connected to the angle adjustment rod 6 through the connecting structure 7. When the welded pipe fitting 8 needs to be adjusted in the horizontal direction, the rotating base 2 or the angle adjustment rod 6 is rotated gently. Under the action of the connecting structure 7, the end of the welded pipe fitting 8 can produce a certain angle change, thereby realizing the angle adjustment of the welded pipe fitting 8 in the horizontal direction.

[0037] In an optional embodiment, a lifting device is also included, which is disposed on the base 1 and is used to adjust the height of the end of the welded pipe 8.

[0038] In this embodiment, the lifting device is connected to the end of the welded pipe 8. Specifically, the end of the welded pipe 8 is mounted on the lifting device. By raising and lowering the lifting device, the end of the welded pipe 8 can be raised and lowered, thereby achieving vertical angle adjustment of the welded pipe 8.

[0039] Specifically, during use, after the welded pipe fitting 8 is placed on the lifting device, the lifting device makes a small adjustment to its height, thereby achieving precise adjustment of the vertical angle of the welded pipe fitting 8.

[0040] In this embodiment, when the connecting structure 7 on the angle adjustment rod 6 is a mounting groove, the mounting groove is a strip-shaped groove, and the end of the welded pipe 8 can slide up and down in the mounting groove under the action of the lifting device.

[0041] In this embodiment, when the connecting structure 7 of the angle adjusting rod 6 is a clamp or other clamping component, the clamping component has a rotation limit between itself and the angle adjusting rod 6, and is slidably connected to the angle adjusting rod 6. It can rotate synchronously with the angle adjusting rod 6, and can slide relative to the angle adjusting rod 6 with the welding pipe 8 when the lifting device drives the welding pipe 8 to rise and fall.

[0042] In an optional embodiment, the lifting device includes a lifting bracket 3 and a lifting support 4; the lifting bracket 3 is fixedly mounted on the base 1, and the lifting support 4 is slidably mounted on the lifting bracket 3; the lifting support 4 is provided with an adjustment gap that allows the angle adjustment rod 6 to pass through.

[0043] In this embodiment, the lifting bracket 3 is fixedly mounted on the base 1. Specifically, the fixing method can be an integral installation, or it can be welding, riveting, bolting, snap-fitting, etc., as long as it can achieve a fixed connection and ensure the stability of the lifting bracket 3.

[0044] In this embodiment, one end of the lifting bracket 4 is slidably mounted on the lifting support 3, and the other end is used to support the welded pipe fitting 8.

[0045] Specifically, in this embodiment, the lifting bracket 4 has an adjustment gap that allows the angle adjustment rod 6 to pass through, thereby enabling both the horizontal and vertical angles of the welded pipe 8 to be adjusted.

[0046] In an optional embodiment, the connection between the lifting bracket 4 and the lifting support 3 is a snap-fit ​​connection, a damping connection, or a bolt connection.

[0047] In this embodiment, the lifting bracket 4 can be connected to the lifting support 3 in different ways to achieve the positioning of the lifting bracket 4 at different heights of the lifting support 3.

[0048] Specifically, in this embodiment, the lifting bracket 4 can be connected to the lifting support 3 by snap-fit. For example, multiple snap-fit ​​slots 15 are provided on the lifting support 3, and snap-fit ​​hooks are provided on the lifting bracket 4. Different snap-fit ​​hooks snap into different snap-fit ​​slots 15 to form different height positioning.

[0049] Specifically, in this embodiment, the lifting bracket 4 can be slidably positioned with the lifting support 3 through a damping connection. For example, a fitting groove is provided at one end of the lifting bracket 4, which fits onto the lifting support 3. A damping pad is provided on the inner wall of the fitting groove and connected to the outer wall of the lifting support 3. This allows the lifting bracket 4 to slide on the lifting support 3 under the action of force, and also allows the lifting bracket 4 to be positioned at a certain height on the lifting support 3 under the action of the damping pad after the force is removed.

[0050] Specifically, in this embodiment, the lifting bracket 4 can be slidably positioned with the lifting support 3 by means of bolt engagement. For example, a fitting groove is provided at one end of the lifting bracket 4, which fits onto the lifting support 3. A threaded hole is provided on the side wall of the fitting groove, and the bolt passes through the threaded hole and abuts against the outer wall of the lifting support 3. When the lifting bracket 4 needs height adjustment, the bolt is turned in the opposite direction to separate it from the lifting support 3. When the lifting bracket 4 reaches the set height, the bolt is turned to engage with the lifting support 3, thus achieving positioning.

[0051] It should be noted that in this embodiment, the connection between the lifting bracket 4 and the lifting support 3 can be as described above, such as snap-fit, damping connection or bolt abutment, but it is not limited to the above methods. It can also be other connection methods, as long as it can achieve positioning between the lifting bracket 4 and the lifting support 3.

[0052] In an optional embodiment, the lifting bracket 4 is provided with a tray 5, and the tray 5 is provided with a positioning groove 12 for positioning the welded pipe 8; the tray 5 is provided with a through hole 16, and the through hole 16 is provided corresponding to the adjustment gap.

[0053] In this embodiment, after the pallet 5 is set on the lifting bracket 4, by replacing different pallets 5, different positioning slots 12 on different pallets 5 can be used to connect with different welded pipe fittings 8, so as to realize the positioning and angle adjustment of different pipe fittings.

[0054] In this embodiment, after the through hole 16 is provided on the tray 5, the angle adjustment rod 6 can pass through the through hole 16 and connect with the welded pipe 8 above the tray 5.

[0055] In an optional embodiment, there are multiple positioning grooves 12, and the width or shape of the multiple positioning grooves 12 are different to accommodate different welded pipe fittings 8.

[0056] In this embodiment, after multiple positioning slots 12 are provided on the tray 5, different welded pipe fittings 8 can be positioned by adjusting the tray 5, thereby reducing the frequency of tray 5 replacement, which is convenient to use and convenient to place and transport the tray 5.

[0057] like Figure 4 As shown, in this embodiment, a slot 17 matching the lifting bracket 4 is provided below the tray 5, and the lifting bracket 4 is inserted into the slot 17 to achieve relative positioning with the tray 5.

[0058] Specifically, in this embodiment, there are multiple slots 17, and the positioning slot 12 can be selected by matching the lifting bracket 4 with different slots 17.

[0059] In an optional embodiment, the tray 5 and the lifting bracket 4 are detachably connected.

[0060] In this embodiment, there are many ways to connect the tray 5 and the lifting bracket 4, such as snap-fit, bolt-fixed connection, adhesive connection and other detachable connection methods.

[0061] In an optional embodiment, the lifting bracket 4 is connected to a power device for driving the lifting bracket 4 to slide on the lifting support 3.

[0062] In this embodiment, a power device is provided on the lifting bracket 4. The power device drives the lifting bracket 4 to slide up and down on the lifting support 3, thereby facilitating angle adjustment.

[0063] Specifically, in this embodiment, the power unit can be an electric motor, a hydraulic cylinder, a pneumatic cylinder, or the like.

[0064] More specifically, in this embodiment, a transmission device, such as a gear transmission mechanism or a rack and pinion transmission mechanism, can also be connected between the power unit and the lifting bracket 4.

[0065] In an optional embodiment, a pointer 10 is connected to the angle adjustment rod 6, and a scale 11 matching the pointer 10 is provided on the rotating base 2.

[0066] In this embodiment, the rotating base 2 is fixed, the angle adjustment rod 6 rotates, and a pointer 10 is set at the lower part of the angle adjustment rod 6. A scale 11 for displaying the rotation angle is set around the pointer 10 on the rotating base 2. Thus, the cooperation between the pointer 10 and the scale 11 can display the torsion angle of the welded pipe 8 in real time.

[0067] The beneficial effects of this utility model embodiment are: The welding pipe 8 is supported by the support frame 9, and the angle adjustment rod 6 is rotated by the rotating base 2, thereby rotating the welding pipe 8 and realizing the angle adjustment of the welding pipe 8, reducing the welding angle error and improving the welding accuracy of the angle.
