[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] To address the risks and shortcomings of existing vacuum flanges with leads during lead welding, placement, and movement, this invention provides a vacuum flange mounting bracket with leads. This bracket greatly facilitates the lead welding process of vacuum flanges, prevents damage to the leads during flange movement or placement, improves the reliability of flange and cable operation, and reduces subsequent maintenance costs.

[0042] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a vacuum flange fixing bracket with lead wires. The vacuum flange fixing bracket includes a base frame 1, a rotating frame 2, a fixed ring clamp 3, a movable ring clamp 4, a stress relief bracket 5 for placing cables, and a positioning screw 6.

[0043] The rotating frame 2 is mounted on the top of the base frame 1 by positioning screws 6. The positioning screws 6 are used to lock and unlock the rotating frame 2, allowing it to rotate relative to the base frame 1 when unlocked. After unlocking the rotating frame 2 with the positioning screws 6, it can be adjusted to any angle. Locking the rotating frame 2 with the positioning screws 6 fixes it in any direction. Figure 1 In the middle, the rotating frame 2 is in a vertical position; as Figure 2 As shown, the rotating frame 2 is in a horizontal state. By tightening the positioning screw 6, the rotating frame 2 can be fixed to the base frame 1, thus achieving a locked state. At this time, the rotating frame 2 cannot rotate relative to the base frame 1. By loosening the positioning screw 6, the rotating frame 2 can be separated from the base frame 1, allowing the rotating frame 2 to rotate around the positioning screw 6 in the vertical plane. After rotating to the desired angle, tightening the positioning screw 6 will lock it in place. When the fixed ring clamp 3 and the movable ring clamp 4 are in... Figure 1 In the vertical position shown, it facilitates operations such as welding leads, rewiring, and disconnecting wires on the flange. The position of the rotating frame 2 relative to the base frame 1 can be adjusted as needed using the positioning screws 6, and the rotation angle can be freely adjusted, facilitating corresponding operations on the flange by the operator.

[0044] like Figure 4 and Figure 5 As shown, the fixed ring clamp 3 and the movable ring clamp 4 are arranged side by side, forming a clamping space for the vacuum flange between the fixed ring clamp 3 and the movable ring clamp 4; the fixed ring clamp 3 is fixedly installed on the rotating frame 2, and the movable ring clamp 4 is slidably installed on the rotating frame 2. The clamping force on the vacuum flange is adjusted by adjusting the distance between the movable ring clamp 4 and the fixed ring clamp 3 by sliding the movable ring clamp 4 along the rotating frame 2. In this embodiment, the sliding of the movable annular clamp 4 on the rotating frame 2 is achieved by adjusting the clamping force 7. Specifically, the clamping force adjusting handle 7 is rotatably mounted on the fixed annular clamp 3 and screwed into the movable annular clamp 4, converting the rotation of the clamping force adjusting handle 7 into linear movement of the movable annular clamp 4 relative to the fixed annular clamp 3. By rotating the clamping force adjusting handle 7, the position of the movable annular clamp 4 is adjusted, thereby adjusting the distance between the movable annular clamp 4 and the fixed annular clamp 3. Furthermore, the clamping force of the movable annular clamp 4 on the flange is adjusted by adjusting the clamping force adjusting handle 7, enhancing the stability of the vacuum flange fixation. To achieve the linear movement of the movable annular clamp 4, the rotating frame 2 is provided with a slide rail extending axially along the fixed annular clamp 3; the movable annular clamp 4 is provided with a slide groove that matches the shape of the slide rail, and the sliding engagement between the slide groove and the slide rail guides the movable annular clamp 4. The slide groove can be a dovetail groove, and the slide rail is a dovetail-shaped slide rail that matches the shape of the dovetail groove. The slide rails and grooves can also adopt other shapes to form the guide structure.

[0045] A pressure relief bracket 5 is installed at each end of the movable annular clamp 4 and the fixed annular clamp 3, opposite to each other. The pressure relief bracket 5 extends outward along the axial direction of the fixed annular clamp 3 and is used to wind the cables of the vacuum flange. The structure of the pressure relief bracket 5 is as follows: Figure 3As shown, the pressure relief bracket 5 installed on the fixed annular clamp 3 extends towards the side opposite to the movable annular clamp 4, and the pressure relief bracket 5 installed on the movable annular clamp 4 extends towards the side opposite to the fixed annular clamp 3. The pressure relief bracket 5 can be threadedly connected to the fixed annular clamp 3 and the movable annular clamp 4; multiple pressure relief brackets 5 are installed on both the movable annular clamp 4 and the fixed annular clamp 3 along the circumference of the fixed annular clamp 3. When the pressure relief bracket 5 is threadedly connected to the fixed annular clamp 3 and the movable annular clamp 4, both ends of the pressure relief bracket 5 can be provided with threads; both the movable annular clamp 4 and the fixed annular clamp 3 are provided with threaded holes, the threaded hole on the movable annular clamp 4 is located at the end opposite to the fixed annular clamp 3, and the threaded hole on the fixed annular clamp 3 is located at the end opposite to the movable annular clamp 4; the end of the pressure relief bracket 5 is fixedly connected to the movable annular clamp 4 and the fixed annular clamp 3 through the threaded engagement of the thread and the threaded hole. Both ends of the pressure relief bracket 5 are threaded, which can be easily connected to the threaded holes of the fixed ring clamp 3 or the movable ring clamp. This makes it easy to wrap and fix the cable welded to the flange on the pressure relief bracket 5, thereby eliminating the downward force of the cable, preventing deformation at the connection between the cable and the flange, and increasing the durability of use.

[0046] An antistatic coating is formed by spraying an antistatic paint onto the outer surface of the vacuum flange holder to meet the high requirements of production environments such as aerospace.

[0047] The vacuum flange mounting bracket with the above structure can effectively protect the copper core connection of the vacuum flange with lead wire from deformation and cracking.

[0048] The aforementioned vacuum flange mounting bracket also includes anti-static silicone strips 8; silicone strips 8 for anti-slip and protection of the vacuum flange are adhered to the opposing surfaces of the movable annular clamp 4 and the fixed annular clamp 3. The silicone strips 8 are directly adhered to the upper and lower inner surfaces of the movable annular clamp 4 and the fixed annular clamp 3. When in contact with the flange, they protect the vacuum flange and prevent slippage, preventing scratches and damage to the vacuum flange, while also meeting anti-static requirements and conforming to the aerospace equipment production environment.

[0049] In the aforementioned vacuum flange mounting bracket, such as Figure 1 and Figure 6 As shown, the base frame 1 includes a chassis, support rods 11, and multiple casters 14 with self-locking function mounted on the bottom of the chassis; the support rods 11 are arranged vertically, with their bottom ends fixedly mounted to the center of the chassis, and their top ends fixedly mounted with rotating frames 2 by positioning screws 6. Figure 6As shown, four casters 14 are installed at the bottom of the chassis, which allow for flexible movement and facilitate the free movement of the vacuum flange mounting bracket in complex environments. Locking the casters 14 also increases the stability of the vacuum flange mounting bracket, thereby improving its mobility.

[0050] like Figure 6 As shown, the chassis also includes a counterweight 15 located at the geometric center; the bottom end of the support rod 11 is fixedly installed on the counterweight 15. By adding the counterweight 15, the center of gravity of the entire vacuum flange mounting bracket can be lowered, improving the stability and ease of movement of the vacuum flange mounting bracket. Locking the casters 14 ensures the stability and reliability of the entire vacuum flange mounting bracket, while unlocking the casters 14 allows the vacuum flange mounting bracket to be easily moved in complex production areas, giving the vacuum flange mounting bracket advantages such as safety, neatness, and convenient movement.

[0051] The chassis can be a ring 12 with a cross 13 fixedly connected inside; the ring 12 can be formed by bending a round tube; the center of the ring 12 coincides with the geometric center of the cross 13; the counterweight 15 is fixedly installed on the center of the cross 13; the casters 14 are evenly installed on the bottom of the ring 12 along the circumference.

[0052] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this utility model without departing from the spirit and scope of this utility model. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
