A stable and high-quality supply of these gases is crucial. Therefore, the cutting, flattening, welding, and processing of ultra-high clean VCR connectors used for their transmission require higher precision and quality.

[0003] Currently, when welding the base of a split 1 / 4VCR connector in the semiconductor field, the loose assembly between components results in low welding repositioning accuracy, easy deformation, and poor welding stability. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a joint clamping and welding device for clamping a welding joint.

The end face of the connector 112 away from the base 111 is coplanar with the end face of the second component 12 away from the base 111.

[0020] The device 100 includes a body 21, multiple mounting members 22, and multiple clamping members 23. The body 21 has a cylindrical structure. One end of the body 21 is provided with multiple mounting grooves 211 evenly arranged radially. The multiple mounting members 22 correspond one-to-one with the multiple mounting grooves 211. The multiple mounting members 22 are movably disposed in their corresponding mounting grooves 211. The multiple clamping members 23 correspond one-to-one with the multiple mounting members 22. The multiple clamping members 23 are all fixed on their corresponding mounting members 22. The multiple clamping members 23 are all located on the outer side of the end face of the body 21 where the multiple mounting grooves 211 are located, so that the multiple clamping members 23 can move radially along the body 21 with their corresponding mounting members 22, which facilitates clamping and fixing the connector 10. The ends of the multiple clamping members 23 away from the body 21 are provided with clamping protrusions 231 radially inward along the body 21. The ends of the clamping protrusions 231 away from their corresponding clamping members 23 are provided with clamping grooves 2311.

[0021] Work process: Please refer to the following: Figures 1 to 4First, insert the end of the connector 112 away from the base 111 into the connecting hole 121 in the middle of the second component 12, and make the end face of the connector 112 away from the base 111 coplanar with the end face of the second component 12 away from the base 111 to complete the initial assembly. Then, place the initially assembled connector 10 between multiple clamping components 23. Next, control multiple mounting components 22 to drive their corresponding clamping components 23 to move radially inward along the body 21 until the side wall of the connector 112 is in contact with the groove wall of the clamping groove 2311 corresponding to the multiple clamping components 23, and the end face of the second component 12 near the base 111 is in contact with the end face of the clamping protrusion 231 corresponding to the multiple clamping components 23 away from the body 21. At this time, the connector 10 is clamped and fixed. Finally, the connector 112 is welded to the connecting hole 121 by argon arc welding or laser welding.

[0022] In order to ensure that the connector 112 will not detach from the connecting hole 121 during the process of the clamping member 23 gradually clamping the connector 112 as it moves radially inward along the body 21, the connector 112 and the connecting hole 121 are interference-fitted.

[0023] To facilitate the placement of the pre-assembled connector 10 between multiple clamping members 23, a first gap exists between adjacent clamping members 23. During clamping, the base 111 enters between multiple clamping members 23 through the first gap between adjacent clamping members 23, and the connector 112 enters between multiple clamping members 23 through the corresponding two clamping protrusions 231. Thus, compared to placing the connector 10 between multiple clamping members 23 from top to bottom, the clamping members 23 do not need to move too far outward along the radial direction of the body 21, making the operation simpler and more convenient.

[0024] To ensure the clamping effect on the connector 10, the number of multiple mounting parts 22, multiple clamping parts 23 and multiple mounting slots 211 shall not be less than 3.

[0025] In order to maximize the movement distance of the multiple mounting parts 22 along their corresponding mounting slots 211, the multiple mounting slots 211 are interconnected at the middle of the body 21.

[0026] To ensure the overall stability and robustness of the device 100, thereby guaranteeing the clamping effect, all mounting slots 211 are inverted T-shaped. Furthermore, all mounting members 22 are H-shaped, with the end of each mounting member 22 near the body 21 engaging with its corresponding mounting slot 211, and the end of each mounting member 22 away from the body 21 being fixedly connected to its corresponding clamping member 23. Even further, each clamping member 23 has a fixing slot 232 at its end near the body 21, the fixing slot 232 being T-shaped, and the end of each mounting member 22 away from the body 21 engaging with the fixing slot 232 on its corresponding clamping member 23.

[0027] In practical use, the device 100 also includes a driving component, which moves multiple mounting components 22 along the mounting groove 211, thereby driving the clamping component 23 to move radially inward along the body 21, so that the groove wall of the clamping groove 2311 fits against the side wall of the connector 112, thereby achieving clamping and fixing of the connector 10. For example, the mounting component 22 is connected to a cylinder via a pull rod.

[0028] This utility model discloses a joint clamping and welding device. Multiple mounting grooves are evenly arranged radially at one end of the main body. Multiple mounting components can be movably installed within their corresponding mounting grooves, and multiple clamping components are fixed to their corresponding mounting components, facilitating the radial movement of the clamping components along with their corresponding mounting components. Clamping protrusions are provided radially inward along the main body at the ends of the clamping components furthest from the main body, and clamping grooves are provided at the ends of the clamping protrusions furthest from their corresponding clamping components, facilitating joint insertion. Simultaneously, the clamping groove walls fit snugly against the side walls of the connecting components to clamp and fix the joint, preventing deformation during welding, ensuring joint welding accuracy, and guaranteeing welding stability.

[0029] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
