Description

Technical Field

[0001] The invention belongs to the technical field of GLS shell welding, and in particular relates to a GLS shell welding flip tool with a protective structure. Background Art

[0002] The GLS (gas insulated switchgear) shell is a key structure for accommodating and protecting the internal components of the GIS, ensuring its safe and reliable operation in high-voltage power systems. It generally requires segmented welding and processing. The flipping tool is a device used to flip the workpiece from one position to another during the manufacturing and assembly process. During the GLS shell welding process, it mainly serves to fix the shell workpiece to cooperate with the welding equipment instead of manually flipping the workpiece, reducing the demand for manpower and improving production efficiency. However, in the prior art, the flipping tool may need to use support members to fix the workpieces one by one after the parts are flipped. This process not only makes the operation cumbersome and increases the time required for the welding operation, but also the quality of the welded product in this case is not easy to guarantee, affecting the subsequent assembly accuracy of the product.

[0003] The existing Chinese patent document with publication number CN112589359B proposes a flip welding tool, which fixes the frame beam, the support assembly and the engine frame respectively through a first positioning component, a second positioning component and a third positioning component. Through the first positioning component, the second positioning component and the third positioning component, the installation positions of the frame beam, the support assembly and the engine frame can be intuitively seen, and the corresponding parts are installed on the corresponding positioning components to solve the above technical problems. However, there is still a problem that there is no protection between the welding parts, and the welding slag generated by welding will splash onto the surface of the workpiece.

[0004] Therefore, the present invention proposes a flip tool with a protective structure for GLS shell welding to solve the problem in the prior art that the flip tool lacks protection after the components are fixed, and the welding slag generated by welding will splash onto the surface of the workpiece. A modular and detachable flip tool is designed, and a protective component in the welding area is added to shield and protect the welding area, thereby improving the welding quality of the GLS shell.

Connect the protection component 7, the welding protection component 7 includes an I-shaped frame 71, the I-shaped frame 71 is fixedly installed on the upper surface of the welding equipment base 1, and telescopic frames 72 are slidably installed on both sides of the I-shaped frame 71, and one end of the telescopic frame 72 is fixedly installed with a welding protection ring 74, and the outer surface of the flip fixed platform 61 is symmetrically fixed with a fixing buckle 611, and the bottom of the outer surface of the flip fixed platform 61 is fixedly installed with a small motor 612, and the inner side of the flip fixed platform 61 is movably installed with a gear 613, and one end of the rotating shaft of the gear 613 is fixedly connected to the output shaft of the small motor 612, and the inside of the flip fixed platform 61 is movably installed with a gear seat 614, and one side surface of the gear seat 614 is meshed with the side surface of the small motor 612, and the other side surface of the gear seat 614 is provided with a locking track 615 adapted to the small motor 612, and the side wall of the flip fixed platform 61 is provided with a limiting slide groove adapted to the movable locking fixed block 62;

[0037] In this embodiment, the fixed flip seat 4 and the movable flip seat 5 can complete the fixation and synchronous flipping of the segmented shells on both sides by cooperating with the shell workpiece flip fixed table assembly 6.

[0038] Embodiment 2

[0039] See also Figures 1 to 15 On the basis of the first embodiment, the present embodiment further proposes that a central positioning shaft 64 is provided in the middle of the inner surface of the flipping fixed platform 61, and a fixed locking block 63 is symmetrically provided on the inner surface of the flipping fixed platform 61. The structure of the fixed locking block 63 is the same as that of the movable locking block 62. The side walls of the flipping fixed platform 61 and the central positioning shaft 64 are both provided with a disk-mounted workpiece fixing block 65. The movable locking fixing block 62 is stepped, and a gripping pad 621 is movably installed on the inner side of the stepped surface of the movable locking fixing block 62. A spring connecting rod 651 is movably installed on the outer surface of the disk-mounted workpiece fixing block 65. The disk-mounted workpiece fixing block 65 is movably installed on the inner side of the movable locking fixing block 62 and the central positioning shaft 64 through the spring connecting rod 651. A buckling pad 652 is hingedly installed on the inner surface of the spring connecting rod 651.

[0040] In this embodiment, the center positioning shaft 64 and the fixed locking block 63 can be fixedly installed on the inner side of the flip fixing platform 61, and can also be detachably installed on the inner side of the flip fixing platform 61 by bolts, so that the flip fixing platform 61 can meet the needs of shell workpieces with different inner diameters, flange body workpieces with different diameters, and the clamping and fixing of bar workpieces. The specific fixing method is that when it is necessary to fix a large-sized shell, after the fixed locking block 63 is installed in a suitable position by bolts, the movable locking block 62 is moved so that the movable locking block 62 cooperates with the fixed locking block 63 to clamp the inner wall of the shell respectively. The fixed locking block 63 and the movable locking block 62 are designed to be stepped, and the internal gripping pad 621 can be freely adjusted according to the thickness of the shell, and the shell with uneven thickness can also be fixed and clamped well, thereby increasing the fixing stability of the large-sized shell. When fixing the small-sized shell, the movable locking block 62 is directly moved to The shell can be clamped inward or outward. When fixing the disc workpiece, the disc workpiece is passed through the center positioning shaft 64 and the movable locking and fixing block 62 is moved inward. At this time, the center positioning shaft 64 and the disc-mounted workpiece fixing block 65 and the spring connecting rod 651 on the movable locking and fixing block 62 are squeezed to fasten the disc from the inside and outside of the disc, and the spring connecting rod 651 increases the fastening effect on the inner and outer side walls of the disc workpiece. When fixing the bar, the center positioning shaft 64 can be removed, and the movable locking and fixing block 62 is tightened inward to complete the fixing of the bar. The modular design of the movable locking and fixing block 62, the fixed locking and fixing block 63, the center positioning shaft 64 and the disc-mounted workpiece fixing block 65 can be quickly replaced or adjusted according to specific needs, thereby improving the flexibility and utilization of the equipment and making the flip tooling highly versatile. It can be used to fix large-size shells, small-size shells, flange disc workpieces and bar workpieces, greatly expanding its application scenarios. In addition, the stepped design of the fixed locking block 63 and the movable locking block 62 allows them to be freely adjusted according to the thickness of the shell, ensuring a good clamping effect even for shells with uneven thickness. For large-sized shells, the coordinated clamping of the fixed locking block 63 and the movable locking block 62 significantly increases the fixing stability and reduces the risk of shaking or displacement of the workpiece during processing. The internal gripping pad 621 can be fine-tuned according to the thickness of the shell to ensure that the clamping force is evenly distributed and to avoid deformation of the workpiece due to excessive local pressure. For the disc workpiece, the disc-mounted workpiece fixing block 65 and the spring connecting rod 651 fasten the disc from the inside and outside, further enhancing the reliability of the fixation.

[0041] Embodiment 3

[0042] See also Figures 1 to 15On the basis of the second embodiment, the present embodiment further proposes that telescopic rods 73 are fixedly installed on both sides of the I-shaped frame 71, and one end of the two sets of telescopic rods 73 is fixedly connected to the inner side wall of the telescopic frame 72, and the telescopic rods 73 are fixedly installed on the inner side of the upper surface of the telescopic frame 72. An auxiliary turning ring 76 is rotatably installed on the side of the telescopic rod 73 close to the welding protection ring 74. A reserved groove 721 matching the auxiliary turning ring 76 is provided on the upper surface of one side of the telescopic frame 72, and an insertion rod 761 matching the fixing buckle 611 is symmetrically fixedly installed on the outer surface of the auxiliary turning ring 76. A fastening clamp 763 is symmetrically provided on the inner side of the auxiliary turning ring 76, and a sawtooth groove is evenly distributed on the inner surface of the fastening clamp 763. A buffer pad 7631 is fixedly installed on the inner wall of the fastening clamp 763, and an adjusting bolt 762 is rotatably installed on the outer surface of the fastening clamp 763. The outer surface of the adjusting bolt 762 is threadedly connected to the side wall of the auxiliary turning ring 76.

[0043] In this embodiment, the telescopic rod 73 can drive the telescopic frame 72 to move on both sides of the I-shaped frame 71. By placing the middle section of the shell on the inner side of the auxiliary flip rings 76 on both sides, the welding position of the shell is adjusted, so that the telescopic frames 72 on both sides are moved respectively under the drive of the telescopic rod 73, so that the welding protection ring 74 can cover the welding area contacted by the shell. During the movement, adjustment is made to ensure that the insertion rod 761 is inserted into the fixing buckle 611, so that the auxiliary flip ring 76 is locked with the flip fixing platform 61, so that the auxiliary flip ring 76 can be turned synchronously with the flipping of the flip fixing platform 61. At this time, the adjusting bolts 762 are rotated in sequence to clamp the shell with the fastening clamp 763. At this time, the welding protection ring 74 also plays a certain limiting role in the process of the fastening clamp 763 fastening the shell, ensuring that the contact position of the shell is flat and improving the quality of the shell welding. The serrated groove on the surface of the fastening clamp 763 can increase the friction with the shell surface. The interior of the buffer pad 7631 is designed as an adsorption groove, so that the shell can be driven to flip by the auxiliary flip ring 76.

[0045] See also Figures 1 to 15 On the basis of the third embodiment, the present embodiment further proposes that a welding groove 741 is provided above the welding protection ring 74, a welding slag baffle 742 is clamped and installed on the inner side of the welding protection ring 74, a welding seam friction ring 7423 is fixedly installed in the middle of the welding slag baffle 742, a notch corresponding to the position of the welding groove 741 is provided above the welding seam friction ring 7423, heat dissipation grooves 7421 are evenly provided on the side wall of the welding slag baffle 742, and micro right-angle heat dissipation fins 7422 corresponding to the position of the heat dissipation grooves 7421 are fixedly installed on the side surface of the welding slag baffle 742;

[0046] In this embodiment, after the segmented shell is assembled, the welding protection ring 74 is positioned to cover the welding area in contact with the shell, the welding groove 741 facilitates the welding gun of the double-station welding equipment 3 to extend into the welding, and the welding slag baffle 742 is a V-shaped ring to protect other areas of the shell to prevent welding slag from splashing and affecting other areas of the shell. The heat dissipation groove 7421 and the micro right-angle heat dissipation fins 7422 mainly serve to increase the heat dissipation of the welding area. The special shape of the micro right-angle heat dissipation fins 7422 can also shield the heat dissipation groove 7421 to prevent welding slag from splashing. The weld friction ring 7423 mainly performs a thermoplastic effect on the weld formed by welding and scrapes off the welding slag to ensure the integrity of the weld and improve the quality of the shell welding.

[0047] Embodiment 5

[0048] See also Figures 1 to 15 Based on the fourth embodiment, this embodiment further proposes a method for using a GLS shell welding flip tool with a protective structure, comprising the following steps:

[0050] Step 2: Install the middle shell, place the middle shell on the inner side of the auxiliary flip rings 76 on both sides, adjust the welding position of the shell, make the telescopic frames 72 on both sides move under the drive of the telescopic rod 73, so that the welding protection ring 74 can cover the welding area contacted by the shell, make adjustments during the movement to ensure that the insertion rod 761 is inserted into the fixing buckle 611, so that the auxiliary flip ring 76 is locked with the flip fixing platform 61, and turn the adjustment bolts 762 in turn to make the fastening clamp 763 clamp and fix the middle shell;

[0051] Step 3: Perform flipping and welding. The welding protection ring 74 covers the welding area of ​​the shell.
