[0034] See Figure 1 , Figure 1 This illustration shows an overall structural diagram of a welding clamping device according to an embodiment of the present application. An embodiment of the present application provides a welding clamping device, comprising:

[0035] Base 10;

[0036] The first clamping assembly 20 for clamping the connector 40 is mounted on the base 10;

[0037] The second clamping assembly 30 is located on the first direction (X) side of the first clamping assembly 20. The second clamping assembly 30 includes a first pipe clamp 31, a second pipe clamp 32, a first drive structure, and a clamping assembly 33. The first pipe clamp 31 and the second pipe clamp 32 are mounted on the base 10 and are arranged opposite each other along the second direction (Y). The first drive structure connects the first pipe clamp 31 and / or the second pipe clamp 32 and is adapted to drive the first pipe clamp 31 and the second pipe clamp 32 to move closer or further apart. The clamping assembly 33 includes a plurality of elastic elements 331, and the plurality of elastic elements 331 of the clamping assembly 33 are distributed on the side where the first pipe clamp 31 and the second pipe clamp 32 face each other. The elastic elements 331 are used to abut against both sides of the pipe 50. In this embodiment, the first drive structure is a lead screw structure, which is convenient for manual control by the user. In other embodiments, other drive forms such as cylinders or telescopic motors can also be used.

[0038] In this embodiment, the first direction (X) intersects the second direction (Y). The angle between the first direction (X) and the second direction (Y) is not specifically limited in this embodiment; for example, it can be 85°, 90°, or 95°. Preferably, the angle between the first direction (X) and the second direction (Y) is 90°, that is, the first direction (X) and the second direction (Y) are perpendicular. For example, the first direction (X) can be the length direction of the base 10, and the second direction (Y) can be the width direction of the base 10. In other embodiments, the first direction (X) is the width direction of the base 10, and the second direction (Y) is the length direction of the base 10.

[0039] During use, the connector 40 can be clamped by the first clamping assembly 20 mounted on the base 10. The first clamping base 10 includes a first pipe clamp 31, a second pipe clamp 32, a first drive structure, and a clamping assembly 33. The first drive structure connects the first pipe clamp 31 and / or the second pipe clamp 32. Rotation of the first drive structure allows the first pipe clamp 31 and the second pipe clamp 32 to move closer and further apart, thereby clamping or releasing the pipe 50. The clamping assembly 33 includes multiple elastic elements 331, which are positioned on opposite sides of the first pipe clamp 31 and the second pipe clamp 32. The elastic elements 331 abut against both sides of the pipe 50 to protect it. This design reduces damage to the pipe 50 during welding.

[0040] After the first clamping assembly 20 and the second clamping assembly 30 clamp the connector 40 and the pipe 50 respectively, the connector 40 and the pipe 50 can be heated by heating devices such as heating plates. After heating is completed, the pipe 50 is inserted into the inner wall of the connector 40, and the two melt and adhere to each other, thus completing the connection between the pipe 50 and the connector 40.

[0041] Specifically, the first clamping assembly 20 includes a first connector clamp 21, a second connector clamp 22, and a second drive structure. The first connector clamp 21 and the second connector clamp 22 are movably mounted on the base 10 and arranged along the second direction (Y). The second drive structure, consisting of the first connector clamp 21 and / or the second connector clamp 22, is adapted to drive the first connector clamp 21 and the second connector clamp 22 to move closer to or further away from each other to clamp or release the connector 40. In this embodiment, the first clamping assembly 20 includes the first connector clamp 21, the second connector clamp 22, and the second drive structure. The first connector clamp 21 and the second connector clamp 22 are arranged along the second direction (Y), and the second drive structure drives the first connector clamp 21 and the second connector clamp 22 to move along the second direction (Y), thereby clamping or releasing the connector 40. In this embodiment, the second drive structure is a lead screw structure. In other embodiments, the second drive structure may also use other drive forms such as a cylinder or a telescopic motor.

[0042] Furthermore, both the first connector clamp 21 and the second connector clamp 22 near the second clamping assembly 30 are provided with baffles 23, which are used to contact the side of the connector 40 near the second clamping assembly 30. Figure 1 As shown, the baffle 23 is used to prevent the connector 40 from continuing to move along the first direction (X) when it is clamped in the first clamping assembly 20, and is used to fix the position of the connector 40 in the first clamping assembly 20.

[0043] Furthermore, the base 10 is provided with a first slide rail 11 arranged along the second direction (Y). The bottom of the first connector clamp 21 and the second connector clamp 22 are both provided with sliders that cooperate with the first slide rail 11, thereby enabling the first connector clamp 21 and the second connector clamp 22 to slide on the base 10. A second driving structure is required to drive the first connector clamp 21 and the second connector clamp 22 to slide on the base 10. Specifically, the second driving structure can be a lead screw structure. The lead screw is rotatably set in the first slide rail 11, and the slider is connected to the lead screw. The end of the lead screw is provided with a handle. By rotating the lead screw through the handle, the first connector clamp 21 and the second connector clamp 22 can be moved on the first slide rail 11, thereby clamping and releasing the connector 40.

[0044] Additionally, the first clamping assembly 20 also includes a stop assembly 24, which is disposed at the ends of the first connector clamp 21 and the second connector clamp 22 away from the second clamping assembly 30. The stop assembly 24 is used to abut against the end of the connector 40 away from the second clamping assembly 30. The stop assembly 24 can be used in conjunction with the baffle 23, the first connector clamp 21, and the second connector clamp 22. The first connector clamp 21 and the second connector clamp 22 can clamp both sides of the connector 40, and the baffle 23 and the stop assembly 24 can respectively abut against both ends of the connector 40.

[0045] In one embodiment, the blocking assembly 24 includes a first blocking member 241 and a second blocking member 242. The first blocking member 241 is connected to the first connector clamp 21, and the second blocking member 242 is connected to the second connector clamp 22. This configuration allows the first blocking member 241 and the second blocking member 242 to be connected to the first connector clamp 21 and the second connector clamp 22, respectively. The first blocking member 241 and the second blocking member 242 can move along the second direction (Y) with the first connector clamp 21 and the second connector clamp 22, thereby increasing or decreasing the distance between the first blocking member 241 and the second blocking member 242, and adapting to abutment connectors 40 of different diameters.

[0046] Specifically, both the first connector clamp 21 and the second connector clamp 22 are provided with a second slide rail 25 extending along a first direction (X) and a third drive structure. Both the first stopper 241 and the second stopper 242 are provided with a second slider, which slides in cooperation with the second slide rail 25. The third drive structure is connected to the second slider to drive it to move along the second slide rail 25. In this embodiment, the third drive structure is a lead screw structure, which is convenient for manual control by the user. In other embodiments, other drive forms such as cylinders or telescopic motors can also be used. The third drive structure allows the first stopper 241 and the second stopper 242 to move back and forth along the second slide rail 25, thereby changing the distance between the stopper assembly 24 and the first connector clamp 21 and the second connector clamp 22. This facilitates clamping the end of the connector 40 and allows for the adaptation to abut connectors 40 of different lengths. Furthermore, during the above process, the first connector clamp 21 and the second connector clamp 22 can also move along the first slide rail 11, thereby achieving clamping between the first connector clamp 21 and the second connector clamp 22. During the clamping process, the first stop 241 and the second stop 242 can move along the second direction to abut against the end of the connector 40.

[0047] Optionally, the elastic element 331 is detachably connected to either the first pipe clamp 31 or the second pipe clamp 32. This arrangement allows for the installation of clamping assemblies 33 of different sizes, thereby accommodating pipes 50 of different sizes.

[0048] To accommodate the shape of the pipe 50, the elastic element 331 has an arc-shaped surface on one side for clamping the pipe 50.

[0049] Furthermore, there are multiple clamping components 33, and the bending radii of the arc surfaces of the elastic elements 331 differ among the multiple clamping components 33. These multiple clamping components 33 can be alternatively connected to the first pipe clamp 31 and the second pipe clamp 32. To accommodate pipes 50 of different sizes, multiple clamping components 33 are provided, each with a corresponding size, and can be replaced onto the first clamping component 20.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
