Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum chamber processing, and in particular relates to a vacuum chamber window flange welding device. Background Art

[0002] The vacuum chamber is one of the main components of the vacuum environment simulation equipment. During the production process of the vacuum chamber, a flange needs to be welded at the vacuum chamber window so that the components installed there can be easily and stably connected to the vacuum chamber, or quickly removed when maintenance or replacement is required.

[0003] A Chinese patent document with authorization announcement number CN221247561U discloses a flange welding device, which clamps the workpiece to be welded with a flange through a transversely movable adjustment device. After the workpiece and the flange are clamped and fitted, the motor drives the component that clamps the flange to rotate, so that the flange and the workpiece rotate together to facilitate welding around the flange.

[0004] However, in the prior art, when the structure of the vacuum chamber is irregular or its window is not centrally arranged, it is difficult for the flange welding device to stably clamp the vacuum chamber while ensuring that the flange to be welded always rotates coaxially with the vacuum chamber window. Therefore, a vacuum chamber window flange welding device is proposed. Utility Model Content

[0008] The first fixing assembly includes a rotating member that can drive the clamped vacuum chamber to rotate horizontally, a reversing member that can adjust the direction of the vacuum chamber window, and a clamping member that can clamp the vacuum chamber and adjust its horizontal position in the device.

[0011] Preferably, the clamping member comprises a second hydraulic rod fixedly connected to the carrier, and a contact plate is fixedly connected to the telescopic end of the second hydraulic rod.

[0012] Preferably, the first shaft seat is rotatably connected to the first rotating shaft.

[0013] Preferably, the turntable is rotatably connected to the carrier, and both the turntable and the carrier are rotatably connected to the first hydraulic rod.

[0014] The beneficial effects of the utility model are as follows: before welding, the vacuum chamber and the flange are fixed respectively by the first fixing assembly and the second fixing assembly, and at the same time, through the action of the reversing member and the clamping member, the vacuum chamber window can be directly opposite to the flange, and the two can be coaxial, so that the two can be aligned and fitted later, thereby ensuring the quality of welding; after the welding operation starts, the vacuum chamber and the flange fitted with the vacuum chamber window are driven by the rotating member to rotate slowly together, so as to speed up the welding operation process.

[0029] The first shaft seat 201 is rotatably connected to the first rotating shaft 202, the turntable 207 is rotatably connected to the carrier 208, and both the turntable 207 and the carrier 208 are rotatably connected to the first hydraulic rod 209;

[0030] The rotation of the output end of the motor 204 is transmitted to the first rotating shaft 202 through the second pulley 205, the belt 206, and the first pulley 203, so as to drive the first rotating shaft 202 to rotate relative to the first shaft seat 201, and the rotated first rotating shaft 202 drives the turntable 207, the carrier 208 and other components to rotate horizontally, and the turntable 207 provides an installation position for the carrier 208 and the first hydraulic rod 209, so that the first hydraulic rod 209 can drive the carrier 208 to rotate relative to the turntable 207, and the vacuum chamber is placed on the carrier 208, and the abutment plate 211 is driven to move by the second hydraulic rod 210, so that each abutment plate 211 can be pressed against the chamber body of the vacuum chamber to fix it on the carrier 208.

[0031] In this embodiment: the second fixed component 3 includes a third hydraulic rod 301 fixedly installed above the frame 101, the telescopic end of the third hydraulic rod 301 is fixedly connected to the lifting frame 302, the upper and lower sides of the lifting frame 302 are fixedly connected to the second shaft seat 303, the second shaft seat 303 is movably connected with the second shaft 304, the lower end of the second shaft 304 is fixedly connected to the rotating frame 305, the rotating frame 305 is movably connected with a clamping rod 306, one end of the clamping rod 306 is fixedly connected to an abutment block 307, a fourth hydraulic rod 308 is fixedly installed in the rotating frame 305, the telescopic end of the fourth hydraulic rod 308 is fixedly connected to a joint 309, and a connecting rod 310 is provided between the clamping rod 306 and the joint 309;
