The first limiting block is perpendicular to the second limiting block. The first limiting block is provided with a first groove, and the second limiting block is provided with a second groove. The first groove is used to clamp the front plate, and the second groove is used to clamp the side plate.

Wherein, in the state where the correction component is in the second position, the correction component is far away from the side plate and the front plate, and the two correction components respectively abut against different side plates. According to the technical solution of this embodiment, the front plate and the two side plates are installed on the panel frame, and through the correction component, the vertical correction between the front plate and the two side plates is realized before welding, thereby improving the manufacturing qualification rate of the gas chamber of the ring main unit.

[0024] Refer to Figures 1 to 3 , this embodiment provides a vertical correction device for a welding jig. The welding jig is used for welding the gas chamber of the ring main unit. The gas chamber of the ring main unit includes a plurality of panels. The panel includes a front plate 100 and two side plates 200. It is characterized in that it includes:

[0025] Panel frame 300, the panel frame 300 includes a first frame 310, two second frames 320 and a third frame 330. The first frame 310 is the upper side of the panel frame 300. The two second frames 320 are parallel to each other and are perpendicularly fixed to the first frame 310. The third frame 330 is perpendicular to both the first frame 310 and the second frames 320 at the same time. The first frame 310 is used for installing the front panel 100. The second frames 320 are used for installing the side panels 200. The third frame 330 does not install a panel. The two side panels 200 are respectively installed on different second frames 320;

[0026] Two calibration components 400, the calibration components 400 are installed on the third frame 330. The calibration components 400 include a driving device 430, a connecting component 440, a first limiting block 410 and a second limiting block 420. The driving device 430 is installed on the panel frame 300. The first limiting block 410 and the second limiting block 420 are connected to the driving device 430 through the connecting component 440. The first limiting block 410 is perpendicular to the second limiting block 420. The first limiting block 410 is provided with a first groove 411, and the second limiting block 420 is provided with a second groove 421. The first groove 411 is used for clamping the front panel 100, and the second groove 421 is used for clamping the side panel 200. The driving device 430 is used for driving the first limiting block 410 and the second limiting block 420 to radially move from the second position to the first position, so that the front panel 100 is clamped into the first groove 411 and the side panel 200 is clamped into the second groove 421. Wherein, in the state where the calibration component 400 is in the second position, the calibration component 400 is far away from the side panel 200 and the front panel 100. The two calibration components 400 respectively abut against different side panels 200.

[0027] It should be noted that the first frame 310, the second frames 320 and the third frame 330 are all rectangular frames. The upper side of the panel frame 300 is the first frame 310, and the second frames 320 are the two sides of the panel frame 300. The positional relationship between the first frame 310 and the second frames 320 is determined by the positional relationship between the front panel 100 and the side panels 200 of the ring main unit gas chamber. This embodiment does not involve structural improvement of the panel of the ring main unit gas chamber.

[0028] It should be noted that the calibration component 400 is installed on the third frame 330, and the calibration component 400 can radially move between the first position and the second position. Those skilled in the art should be able to understand that in order to avoid the first limiting block 410 and the second limiting block 420 from colliding and damaging the front panel 100 and the side panels 200, the radial movement direction of the calibration component 400 should be a straight line direction perpendicular to the third frame 330. One calibration component 400 is used for vertically calibrating one side panel 200 and the front panel 100. In order to achieve the vertical calibration effect, during the radial movement of the calibration component 400, the first limiting block 410 is perpendicular to the front panel 100, and the second limiting block 420 is perpendicular to the side panel 200.

[0029] It should be noted that the driving device 430 can drive the connecting component 440 to move radially. The radial movement of the connecting component 440 can drive the first limiting block 410 and the second limiting block 420 to move radially. The radial movement direction of the connecting component 440 is the same as that of the first limiting block 410 and the second limiting block 420.

[0030] It should be noted that when the calibration component 400 is in the second position, the front plate 100 is placed on the first frame 310, and the two side plates 200 are respectively installed on different second frames 320. The first limiting block 410 and the front plate 100 are at the same height and have a certain horizontal distance. The first limiting block 410 does not abut against the front plate 100, and the second limiting block 420 does not abut against the side plate 200. The driving device 430 works. The driving device 430 drives the first limiting block 410 and the second limiting block 420 to move radially through the connecting component 440. The front plate 100 enters the first groove 411, and the side plate 200 enters the second groove 421 until the first groove 411 is clamped to the front plate 100 and the second groove 421 is clamped to the side plate 200. At this time, the calibration component 400 is in the first position. Since the first limiting block 410 and the second limiting block 420 are perpendicular to each other, the front plate 100 clamped by the first groove 411 and the side plate 200 clamped by the second groove 421 are vertically calibrated. When the vertical calibration of the front plate 100 and the side plate 200 abutted by the calibration component 400 is completed, the driving device 430 drives the first limiting block 410 and the second limiting block 420 to move radially from the first position to the second position, so that the calibration component 400 will not hinder the subsequent welding process of the gas chamber of the ring main unit.

[0031] In addition, in an embodiment, referring to Figures 1 to 3 , the longitudinal section of the first groove 411 is trapezoidal. The side of the first groove 411 close to the connecting component 440 is the inner side. The inner side of the first groove 411 is the shorter side. The inner side of the first groove 411 communicates with the first notch. The longitudinal section of the first notch is rectangular. The first notch is used to clamp the front plate 100. The side of the second groove 421 close to the connecting component 440 is the inner side. The longitudinal section of the second groove 421 is trapezoidal. The inner side of the second groove 421 is the shorter side. The inner side of the second groove 421 communicates with the second notch. The longitudinal section of the second notch is rectangular. The second notch is used to clamp the side plate 200.

[0032] It should be noted that referring to Figure 1 and Figure 2, the front panel 100 enters the first groove 411 from the longer side of the trapezoid in the longitudinal section of the first groove 411. The longer side of the trapezoid allows the alignment component 400 to have a certain position redundancy space, enabling the un-vertically aligned front panel 100 to be fed into the first groove 411. Through the hypotenuse of the trapezoid in the longitudinal section of the first groove 411, during the process of the alignment component 400 moving from the second position to the first position, the position of the front panel 100 is finely adjusted, bringing the first notch closer to the front panel 100, thereby realizing that the first notch is snapped onto the front panel 100. To achieve a better positioning effect, the width of the first notch is the same as the thickness of the abutted front panel 100.

[0033] It should be noted that, referring to Figure 1 and Figure 2 , the side panel 200 enters the second groove 421 from the longer side of the trapezoid in the longitudinal section of the second groove 421. The longer side of the trapezoid allows the alignment component 400 to have a certain position redundancy space, enabling the un-vertically aligned side panel 200 to be fed into the second groove 421. Through the hypotenuse of the trapezoid in the longitudinal section of the second groove 421, during the process of the alignment component 400 moving from the second position to the first position, the position of the side panel 200 is finely adjusted, bringing the second notch closer to the side panel 200, thereby realizing that the second notch is snapped onto the side panel 200. To achieve a better positioning effect, the width of the second notch is the same as the thickness of the abutted side panel 200.

[0034] In addition, in one embodiment, referring to Figure 3 , the connection component 440 includes a first connecting rod 441 and a second connecting rod 442. One end of the first connecting rod 441 is connected to the driving device 430, the other end of the first connecting rod 441 is connected to one end of the second connecting rod 442, and the other end of the second connecting rod 442 is used to connect the first limiting block 410 and the second limiting block 420.

[0035] It should be noted that the driving device 430 drives the first connecting rod 441 to move radially, the first connecting rod 441 drives the second connecting rod 442 to move radially, and the second connecting rod 442 is used to drive the first limiting block 410 and the second limiting block 420 to move radially, so that the driving device 430 drives the alignment component 400 to move radially from the second position to the first position.

[0036] In addition, in one embodiment, referring to Figures 1 to 3, further comprising an adapter plate 450. The adapter plate 450 is fixed to the second connecting rod 442. The adapter plate 450 is provided with two third notches 451. The first limiting block 410 is provided with a third groove 412 and a first convex block 413. The second limiting block 420 is provided with a second convex block 422 and a third convex block 423. The second convex block 422 is inserted into the third groove 412. The first limiting block 410 is inserted into one of the third notches 451 through the first convex block 413. The second limiting block 420 is inserted into the other third notch 451 through the third convex block 423.

[0037] It should be noted that the first limiting block 410 and the second limiting block 420 are connected to the second connecting rod 442 through the adapter plate 450. By driving the radial movement of the adapter plate 450, the second connecting rod 442 drives the first limiting block 410 and the second limiting block 420 to move radially.

[0038] It should be noted that to achieve a high-precision vertical positioning effect, the widths of the first notch and the second notch are both the same as the panel widths of the abutted front plate 100 and side plate 200. The first limiting block 410 and the second limiting block 420 are both inserted into the adapter plate 450, so that the vertical correction assembly 400 of this embodiment can adapt to front plates 100 and side plates 200 with different thicknesses. Only by replacing the first limiting block 410 or the second limiting block 420 with different thicknesses and inserting them into the third notch 451 of the adapter plate 450 can the vertical correction of panels with different thicknesses be achieved through this embodiment.

[0039] In addition, in one embodiment, referring to Figures 1 to 3 , the driving device 430 is a cylinder. The cylinder includes a cylinder barrel 431 and a piston rod 432. One end of the piston rod 432 is connected to the first connecting rod 441. The piston rod 432 makes axial and circumferential movements within the cylinder barrel 431. The piston rod 432 drives the first connecting rod 441 to make radial and circumferential movements.

[0040] It should be noted that the cylinder can be installed inside the panel frame 300, thereby reducing the volume of the vertical correction device. The axial movement direction of the piston rod 432 is a straight line direction perpendicular to the third frame 330. The first connecting rod 441 is vertically fixed to the piston rod 432. The axial movement of the piston rod 432 drives the first connecting rod 441 to make radial movement, thereby realizing the radial movement of the first limiting block 410 and the second limiting block 420. The radial movement directions of the first limiting block 410 and the second limiting block 420 are the same as the axial movement direction of the piston rod 432. The circumferential movement of the piston rod 432 drives the first connecting rod 441 to make circumferential movement along the connection with the piston rod 432. The circumferential movement trajectory of the first connecting rod 441 is parallel to the third frame 330.

[0041] It should be noted that, for the convenience of installing the front panel 100 and the side panels 200 on the first frame 310 and the second frame 320, when the calibration assembly 400 is in the third position, the heights of the first limiting block 410 and the second limiting block 420 are lower than that of the front panel 100, and there is a certain horizontal distance between the first limiting block 410 and the second limiting block 420 and the front panel 100 and the side panels 200; when the air cylinder works, the piston rod 432 makes a circumferential movement in the cylinder barrel 431, and the piston rod 432 drives the first connecting rod 441 to make a circumferential movement. The first connecting rod 441 rotates from the third position to the second position. At this time, the height of the first groove 411 is the same as that of the front panel 100, and there is a certain horizontal distance between the first limiting block 410 and the second limiting block 420 and the front panel 100 and the side panels 200; the piston rod 432 makes an axial movement inside the cylinder barrel 431, driving the first connecting rod 441 to make a radial movement. The first connecting rod 441 drives the first limiting block 410 and the second limiting block 420 to radially move from the second position to the first position by driving the second connecting rod 442 and the adapter plate 450, so that the first groove 411 is clamped to the front panel 100, and the second groove 421 is clamped to the side panel 200. When the calibration assembly 400 completes the vertical calibration of the abutted front panel 100 and side panels 200, the first limiting block 410 and the second limiting block 420 radially move from the first position to the second position, and then rotate from the second position to the third position.

[0042] In addition, the front panel 100 is provided with at least one through hole. In one embodiment, referring to Figure 1 and Figure 2 , it further includes a first auxiliary plate 500. The first auxiliary plate 500 is installed on the first frame 310, and the first auxiliary plate 500 is provided with a first positioning shaft 510. The first positioning shaft 510 passes through the through hole of the front panel 100.

[0043] It should be noted that during the manufacturing process of the ring main unit gas chamber, parts need to be installed at the through holes of the cabinet body of the already welded ring main unit gas chamber. The cabinet body of the ring main unit includes a front panel 100, and the front panel 100 is provided with through holes for installing parts. This application does not make improvements to the structure of the front panel 100. In this embodiment, only the original through holes of the front panel 100 are used as the positioning auxiliary holes of the front panel 100.

[0044] It should be noted that the front panel 100 is placed on the first frame 310 with its through hole aligned with the first positioning shaft 510. The first positioning shaft 510 provides a structural basis for the preliminary positioning of the front panel 100 installed on the first frame 310, so that during the process of the calibration assembly 400 radially moving from the second position to the first position, the front panel 100 can enter the first groove 411, and the first notch can be clamped to the front panel 100.

[0045] In addition, in one embodiment, referring toFigure 2 and Figure 3 further includes a positioning plate 600, the positioning plate 600 is installed on the first auxiliary plate 500, the positioning plate 600 is provided with a positioning hole 610, and the piston rod 432 movably penetrates through the positioning hole 610.

[0046] It should be noted that the positioning plate 600 is vertically installed on the first auxiliary plate 500, and the positioning hole 610 and the positioning plate 600 are provided to ensure that the axial movement direction of the piston rod 432 is stable and fixed, and to avoid deviation of the axial movement direction of the piston rod 432 due to long-term use of the piston rod 432, thereby resulting in poor vertical correction effect.

[0047] In addition, the side plate 200 is provided with at least one through hole. In one embodiment, referring to Figure 1 and Figure 2 further includes a second auxiliary plate 700, the second auxiliary plate 700 is installed on the second frame 320, the second auxiliary plate 700 is provided with a second positioning shaft 710, and the second positioning shaft 710 penetrates through the through hole of the side plate 200.

[0048] It should be noted that during the manufacturing process of the ring main unit gas chamber, parts need to be installed at the through holes of the cabinet body of the already welded ring main unit gas chamber. The cabinet body of the ring main unit includes a side plate 200, and the side plate 200 is provided with through holes for installing parts. This application does not make improvements to the structure of the side plate 200. This embodiment only uses the original through holes of the side plate 200 as the positioning auxiliary holes of the side plate 200.

[0049] It should be noted that the side plate 200 is placed on the second frame 320 with the through hole aligned with the second positioning shaft 710. The installation of the side plate 200 on the second frame 320 is preliminarily positioned by the second positioning shaft 710, providing a structural basis for the vertical correction of the front plate 100 and the side plate 200 by the correction assembly 400. During the process of the correction assembly 400 radially moving from the second position to the first position, the side plate 200 can enter the second groove 421, and the second notch can be clamped to the side plate 200.

[0050] In addition, in one embodiment, referring to Figure 1 and Figure 2 further includes a suction cup 800 and a trigger device 900. The suction cup 800 and the trigger device 900 are installed on the second frame 320, the suction cup 800 is connected to the trigger device 900, the suction cup 800 abuts against the side plate 200, and the trigger device 900 abuts against the side plate 200.

[0051] It should be noted that when the side plate 200 is placed on the second frame 320, the triggering device 900 abuts against the side plate 200. The triggering device 900 generates an electrical signal and transmits the electrical signal to the suction cup 800. The suction cup 800 operates to adsorb the side plate 200 to the second frame 320, thereby preventing the side plate 200 from tipping under the action of gravity.

[0052] It should be noted that the triggering device 900 is used to provide a start signal for the suction cup 800 and can confirm whether the side plate 200 is installed in place. The suction force of the suction cup 800 on the side plate 200 is limited, enabling the calibration assembly 400 to vertically calibrate the side plate 200 so that the front plate 100 and the side plate 200 are perpendicular to each other.

[0053] It should be noted that the calibration assembly 400 is located at the third position. The heights of the first limiting block 410 and the second limiting block 420 are lower than that of the front plate 100 and do not abut against the front plate 100 and the side plate 200. Align the through hole of the front plate 100 with the first positioning shaft 510 and place the front plate 100 on the first frame 310. Align the through hole of the side plate 200 with the second positioning shaft 710 and place the side plate 200 on the second frame 320. The air cylinder operates to drive the piston rod 432 to perform a circumferential movement within the cylinder barrel 431. The piston rod 432 drives the first connecting rod 441, the second connecting rod 442, and the adapter plate 450 to drive the first limiting block 410 and the second limiting block 420 to perform a circumferential movement, causing the calibration assembly 400 to rotate from the third position to the second position. At this time, the heights of the first limiting block 410 and the second limiting block 420 are the same as that of the front plate 100 and do not abut against the front plate 100 and the side plate 200. The air cylinder drives the piston rod 432 to perform an axial movement within the cylinder barrel 431. The piston rod 432 drives the first connecting rod 441, the second connecting rod 442, and the adapter plate 450 to drive the first limiting block 410 and the second limiting block 420 to perform a radial movement, causing the first groove 411 to be clamped to the front plate 100 and the second groove 421 to be clamped to the side plate 200, achieving the vertical calibration of the front plate 100 and the side plate 200. When the calibration assembly 400 completes the vertical calibration of the front plate 100 and the side plate 200, the calibration assembly 400 radially moves from the first position to the second position and rotates from the second position to the third position, making the front plate 100 and the side plate 200 perpendicular to each other, and the vertical calibration device will not affect the subsequent welding process of the ring main unit gas chamber.

[0054] In addition, the embodiment of the present utility model also provides a welding jig, including the above Figures 1 to 3 vertical calibration device.

[0055] It should be noted that the welding jig can be the vertical calibration device itself or other devices applying the vertical calibration device, such as the welding jig for the ring main unit gas chamber, etc. The specific type of the welding jig is not limited in this embodiment, as long as it can apply the above vertical calibration device.

The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include common general knowledge or conventional technical means in the technical field not disclosed in the present application.

[0057] It should be understood that the present application is not limited to the exact structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present application is only limited by the appended claims.

[0058] The above is a specific description of the preferred embodiment of the present utility model, but the present utility model is not limited to the above embodiments. Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of the present utility model, and these equivalent deformations or substitutions are all included within the scope defined by the claims of the present utility model.
