[0002] As shown in Figures 1 and 2, the transformer includes components such as a bucket cover 81, a high-voltage bushing 82, a connecting terminal 83, and a spinning ring 84. When assembling the transformer, the connecting terminal 83 needs to be fixed to the metal wire of the high-voltage bushing 82 by threaded connection first, and then the high-voltage bushing 82 is inserted into the positioning hole of the bucket cover 81 and tightened by the spinning ring 84.

[0003] The conventional assembly method involves manually tightening the components with a wrench. When tightening, the high-pressure sleeve 82 is prone to deflection, making it difficult to tighten the connecting terminal 83. When assembling the bucket cover 81, the high-pressure sleeve 82, and the pressure ring 84, two workers are required to operate together, resulting in high labor costs.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0039] Example 1

[0040] As shown in Figures 1 to 10, this embodiment discloses a single-phase column-mounted transformer drum cover assembly device, including:

[0041] First support 10;

[0042] The first fixing mechanism 20 includes a first mounting base 21 fixed to the first bracket 10, and two first sliding seats 22 disposed on the first mounting base 21 and adjustable in position along the x direction. The first sliding seats 22 are provided with a first limiting groove 221.

[0043] The second fixing mechanism 30 includes a first fixed mold 31, a first moving mold 32, a second moving mold 33, and a second fixed mold 34 arranged sequentially along the y-direction on the first support 10. The first fixed mold 31 and the first moving mold 32 cooperate to form a first clamping hole 301, and the second fixed mold 34 and the second moving mold 33 cooperate to form a second clamping hole 302. The first fixed mold 31 and the second fixed mold 34 are both fixed to the first support 10. A driving component 35 for driving the first moving mold 32 and the second moving mold 33 to move synchronously relative to each other or in opposite directions is provided between them.

[0044] The second support 40 is fixed to the upper end of the first support 10. The second support 40 is provided with a lifting device 41 driven along the z direction. The output end of the lifting device 41 is connected to the carrier 42.

[0045] The first tightening mechanism 50 includes a second mounting base 51 fixed to the carrier 42, two second sliding seats 52 disposed on the second mounting base 51 and adjustable in position along the x direction, a first rotary drive device 53 fixed to the lower end of the second sliding seats 52, and a sleeve 54 connected to the output end of the first rotary drive device 53. The lower end of the sleeve 54 is provided with a plurality of circumferentially distributed protrusions 541.

[0046] The second tightening mechanism 60 includes two second rotary drive devices 61 fixed to the carrier 42 and a cap 62 connected to the output end of the second rotary drive device 61. The lower end of the cap 62 is provided with a slot 621.

[0047] The single-phase column-mounted transformer barrel cover assembly equipment of this embodiment is provided with a second fixing mechanism 30 and a second tightening mechanism 60. When assembling the high-voltage bushing 82 and the connecting terminal 83, as shown in Figures 1 to 3, the cylindrical lower end of one high-voltage bushing 82 is first inserted into the first clamping hole 301 formed by the first fixed mold 31 and the first moving mold 32, and the cylindrical lower end of the other high-voltage bushing 82 is inserted into the second clamping hole 302 formed by the second fixed mold 34 and the second moving mold 33. The first moving mold 32 and the second moving mold 33 are driven to move synchronously relative to each other through the driving component 35, so that the first clamping hole 301, The second clamping holes 302 clamp the cylindrical lower ends of the two high-pressure bushings 82 respectively. Then, the two connecting terminals 83 are placed at the upper threaded conduit positions of the two high-pressure bushings 82 respectively. The lifting device 41 drives the carrier 42 to move down, thereby driving the two caps 62 to move down until the slots 621 of the two caps 62 are respectively engaged with the protruding positions of the two connecting terminals 83. The two second rotation driving devices 61 drive the two caps 62 to rotate respectively, so that the two connecting terminals 83 are respectively threadedly connected to the upper threaded conduits of the two high-pressure bushings 82. No manual rotation and tightening is required, resulting in high assembly efficiency.

[0048] This embodiment also includes a first fixing mechanism 20 and a first tightening mechanism 50. When assembling the barrel cover 81, the high-pressure sleeve 82, and the spinning ring 84, the high-pressure sleeve 82 with the connecting terminal 83 installed is first inverted, and the connecting terminal 83 is inserted into the first limiting groove 221 of the first sliding seat 22. Then, the lower end of the high-pressure sleeve 82 is passed through the through hole of the barrel cover 81, and then the spinning ring 84 is installed. The lifting device 41 drives the carrier 42 to move down, thereby driving the sleeve 54 to move down until the protruding tooth 541 of the sleeve 54 is inserted into the tooth groove of the spinning ring 84. The first rotation driving device 53 drives the sleeve 54 to rotate, thereby connecting the spinning ring 84 with the threaded part of the high-pressure sleeve 82. No manual rotation and tightening is required, resulting in high assembly efficiency and reduced labor costs.

[0049] This embodiment can complete the assembly of two components simultaneously, reducing equipment costs; moreover, the lifting is controlled simultaneously by a lifting device 41, which is ingenious in structure.

[0050] Furthermore, in this embodiment, both the first rotary drive device 53 and the second rotary drive device 61 adopt torque-adjustable servo motors. The torque can be adjusted by changing the driver settings of the servo motor, thereby adjusting the torque of the sleeve 54 and the cap 62 to 15-25N, so that the two connecting terminals 83 are more tightly connected to the upper threaded tubing of the two high-pressure sleeves 82, and the screw ring 84 is more tightly connected to the threaded part of the high-pressure sleeve 82.

[0051] Please refer to Figures 4 and 5. In this embodiment, the first mounting base 21 is provided with a first sliding groove 211 along the x-direction, and a first sliding seat 22 is disposed in the first sliding groove 211. Both sides of the first sliding seat 22 along the y-direction are connected to a first locking member 222. Both sides of the first sliding groove 211 along the y-direction are provided with a first mounting hole 212 for adjusting the position of the first locking member 222 along the x-direction. The second mounting base 51 is provided with a second sliding groove 511 along the x-direction, and a second sliding seat 52 is disposed in the second sliding groove 511. Both sides of the second sliding seat 52 along the y-direction are connected to a second locking member 521. Both sides of the second sliding groove 511 along the y-direction are provided with a second mounting hole 512 for adjusting the position of the second locking member 521 along the x-direction. The positions of the first sliding seat 22 and the second sliding seat 52 along the x-direction can be adjusted according to the product specifications to adapt to the assembly of products of different specifications.

[0052] Further, please refer to Figure 4. In this embodiment, the upper end of the first bracket 10 is provided with a partition 11. The partition 11 is used to support the upper end of the high-pressure bushing 82 and the bucket cover 81. The partition 11 is provided with a clearance hole 12, a first positioning hole 13 and a second positioning hole 14. The first positioning hole 13 is located above the first clamping hole 301, and the second positioning hole 14 is located above the second clamping hole 302. When assembling the high-pressure bushing 82 and the connecting terminal 83, the two high-pressure bushings 82 pass through the first positioning hole 13 and the second positioning hole 14 from top to bottom. The first positioning hole 13 and the second positioning hole 14 are used to pre-position the two high-pressure bushings 82, so that the workers can quickly insert the cylindrical lower ends of the two high-pressure bushings 82 into the first clamping hole 301 and the second clamping hole 302. The clearance hole 12 is located above the first mounting base 21. The clearance hole 12 is used to pre-position the high-pressure bushing 82, and the clearance hole 12 is set to extend along the x-direction to facilitate the installation of two high-pressure bushings 82 with different intervals.

[0053] Please refer to Figures 6 to 10. The drive assembly 35 in this embodiment includes a first motor 351 fixed to the first bracket 10, a cam 352 connected to the output end of the first motor 351, a first spring 353 for connecting the first fixed mold 31 and the first moving mold 32, and a second spring 354 for connecting the second fixed mold 34 and the second moving mold 33. The cam 352 has two protrusions and is located between the first moving mold 32 and the second moving mold 33. The cam 352 enables the first moving mold 32 and the second moving mold 33 to move synchronously relative to each other or in opposite directions, thereby clamping or releasing the two high-pressure bushings 82 at the same time. The structure is ingenious.

[0054] Furthermore, since the preset heights of the cap 62 and sleeve 54 are different for different product models, in order to adjust the relative height of the cap 62 and sleeve 54, two height adjustment components 70 with adjustable z-axis height are connected and fixed to the lower end of the carrier 42. Two second rotary drive devices 61 are respectively fixed to the output ends of the two height adjustment components 70. The height adjustment component 70 can be a shell, an inner core that moves along the z-axis in the shell, and bolt fasteners for locking the shell and the inner core. The shell is provided with waist holes for adjusting the position of the bolt fasteners along the z-axis. The lower end of the inner core is the output end of the height adjustment component 70.

[0055] Furthermore, in order to improve the stability of the carrier 42 moving along the z-direction, the second support 40 is provided with a guide rod 43, and the carrier 42 is provided with a guide hole that cooperates with the guide rod 43.

[0056] Furthermore, the first bracket 10 is provided with an operation panel 15, which is provided with a lifting button for controlling the lifting device 41, a first tightening button for controlling the first rotary drive device 53, and a second tightening button for controlling the second rotary drive device 61.

[0057] Example 2

[0058] As shown in Figures 11 and 12, the difference between this embodiment and Embodiment 1 is that the second bracket 40 in this embodiment is provided with a first z-axis drive device 91 and a second z-axis drive device 92 driven along the z-direction. The first z-axis drive device 91 and the second z-axis drive device 92 can be ball screw modules to precisely control the stroke of the z-axis movement. The second mounting base 51 is fixed to the output end of the first z-axis drive device 91, and the second rotary drive device 61 is fixed to the output end of the second z-axis drive device 92, so that the lifting of the first tightening mechanism 50 and the second tightening mechanism 60 can be controlled independently to adapt to the assembly of products of different sizes.

[0059] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present invention.
