Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, in particular to a welding positioning device for processing a gas box of a gas-insulated switchgear. Background Art

[0002] A welding positioning device for gas-insulated switchgear gas boxes is a mechanical device specifically designed for precise positioning and welding of gas boxes during the production process. This device typically includes multiple positioning mechanisms and clamping mechanisms. The welding positioning device is designed to improve welding quality and production efficiency while reducing labor intensity and production costs, thus requiring assistance.

[0003] Common welding positioning devices include a screw and a clamping plate. When in use, the screw is rotated to drive the opening and closing movement of the clamping plate, so that the gas box workpiece can be clamped and positioned. However, since the gas box needs to be welded in different orientations on multiple sides and surfaces during welding, when the orientation needs to be changed, the gas box needs to be removed first and then the angle needs to be adjusted, and finally clamped and positioned. This makes the entire welding process time-consuming and labor-intensive, and frequent clamping reduces the positioning accuracy, which cannot meet the working requirements of welding positioning. For this reason, a welding positioning device for gas-insulated switchgear gas box processing is proposed. Utility Model Content

The inside of the bracket is screwed with a threaded rod, and the bottom end of the threaded rod is installed with an insert through a bearing.

[0012] Preferably, a turntable is coaxially mounted on the left end of the screw to facilitate the rotation of the screw, and a side plate is mounted on the right side of the inner portion of the slide groove. The right end of the screw is connected to the corresponding position of the side plate through a ball bearing, thereby improving the stability of the screw during rotation.

[0013] Preferably, the bottom shapes of the side panels and the slide are both trapezoidal, the left and right sides of the bottom of the slide are both rounded, and the left and right threads of the screw are set in opposite directions, which facilitates the slide to move in opposite directions when the screw rotates.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a technical solution, a welding positioning device for processing a gas box of a gas-insulated switchgear, comprising a base 1, a slide 2, a mounting block 3, a slide 4, a bearing sleeve 5, a lead screw 6, a turntable 7, a side plate 8, a mounting frame 9, an insert shaft 10, a chuck 11, a slot 12, a bracket 13, a threaded rod 14, an insert block 15, a handwheel 16, a mounting plate 17, a positioning clamping plate 18, a limiting hole 19 and a bolt 20:

[0027] See also Figure 1The base 1 has a chute 2 in the middle, and a mounting block 3 is inserted into the middle of the chute 2. Figure 2 , a bearing sleeve 5 is inserted into the middle position of the inner portion of the mounting block 3;

[0028] The slide 4 is inserted into the left and right sides of the slide 2, and the bearing sleeve 5 is inserted into the inside of the screw 6. The left and right sides of the screw 6 pass through the interior of the slide 4. The left end of the screw 6 is coaxially mounted with a turntable 7. A side plate 8 is mounted on the right side of the slide 2. The right end of the screw 6 is connected to the corresponding position of the side plate 8 through a ball bearing. The bottom shape of the side plate 8 and the slide 4 are both trapezoidal. The left and right sides of the bottom of the slide 4 are both rounded. The threads on the left and right sides of the screw 6 are set in opposite directions to each other.

[0029] See also Figure 1 , mounting bracket 9, mounted on the top middle position of the slide 4, please refer to Figure 3 , the inner middle position of the mounting frame 9 is inserted with an insertion shaft 10, the left and right ends of the insertion shaft 10 pass through the corresponding positions on the left and right sides of the mounting frame 9, and the left end of the left insertion shaft 10 is coaxially mounted with a chuck 11;

[0030] The slot 12 is circumferentially opened on the inner and outer sides of the chuck 11. The left side of the top of the left mounting frame 9 is connected to a bracket 13. A threaded rod 14 is screwed inside the bracket 13. An insert 15 is installed at the bottom end of the threaded rod 14 through a bearing. The number of the slots 12 is 4-8 groups. The shape and size of the insert 15 are adapted to the slot 12. The left and right sides of the bottom of the insert 15 are chamfered. A hand wheel 16 is coaxially installed at the top of the threaded rod 14. By rotating the lead screw 6 to drive the movement of the slide 4, the slides 4 on the left and right sides can be made to move in opposite directions, so that the air box workpiece can be clamped and positioned. When the orientation needs to be changed, it is only necessary to rotate the hand wheel 16 to drive the rotation of the threaded rod 14, thereby disengaging the insert 15 from the slot 12.

[0032] This solution drives the movement of the slide 4 by rotating the screw 6, so that the slides 4 on the left and right sides can perform opposite closing movements, thereby clamping the air box workpiece in position. When the orientation needs to be changed, it is only necessary to rotate the handwheel 16 to drive the rotation of the threaded rod 14, so that the insert block 15 can be disengaged from the inside of the slot 12, so that the rotation of the insert shaft 10 and the mounting plate 17 can be driven by rotating the chuck 11, which makes it convenient to adjust the angle of the air box without disassembly and assembly, avoids repeated disassembly and assembly of the air box during positioning, and improves the convenience and accuracy of welding the air box.
