DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments

[0027] Referring to Figures 1-8 As shown in the figure, a cutting device for transformer encapsulation, including cutting equipment 1, the top of cutting equipment 1 is provided with rotatable feed round table 3, the top of feed round table 3 is provided with hollow transformer main body 8, the center of the top of feed round table 3 is provided with the limiting sleeve 32 that can extend to the inner ring of transformer main body 8;The inside of limiting sleeve 32 is provided with spline shaft 41 that can move longitudinally, the both sides of the top of spline shaft 41 are longitudinally provided with two groups of support plates 5 that can support the inner ring of transformer main body 8;The top of spline shaft 41 is provided with inner support mechanism 42 for driving support plate 5 to be close to each other or away from each other;The center of the bottom of feed round table 3 is longitudinally provided with hydraulic telescopic assembly 4 for driving spline shaft 41 reciprocating movement along the central axis direction of limiting sleeve 32;The bottom end of spline shaft 41 is fixedly connected with the output end of hydraulic telescopic assembly 4, the bottom of cutting equipment 1 is provided with driving mechanism 2 for driving feed round table 3 to rotate;The both sides of the top of limiting sleeve 32 are hingedly provided with the second support rod 7 for supporting support plate 5.

[0028] First, the transformer main body 8 is placed on the top of feed round table 3, ensure that limiting sleeve 32 can be accurately inserted into the inside of transformer main body 8.Subsequently, spline shaft 41 is driven to move longitudinally along the inside of limiting sleeve 32 by hydraulic telescopic assembly 4.When spline shaft 41 is driven to go up by hydraulic telescopic assembly 4, spline shaft 41 drives support plate 5 to be away from each other by inner support mechanism 42.At this time, the outer surface of the two groups of support plates 5 is tightly extruded the surface wall of the inner ring of transformer main body 8, so that support plate 5 effectively fixes transformer main body 8.On the contrary, when spline shaft 41 is driven to go down by hydraulic telescopic assembly 4, spline shaft 41 drives support plate 5 to be close to each other by inner support mechanism 42, and then makes the surface of support plate 5 and the inner ring of transformer main body 8 separate.At this time, transformer main body 8 is in a non-fixed state, only the whole transformer main body 8 is taken off from feed round table 3, the dismounting process can be completed, thereby improving the dismounting and installation efficiency of transformer main body 8.

[0029] Referring to Figure 7 And Figure 8 As shown in the figure, the outside of the top of spline shaft 41 is provided with inner support mechanism 42, inner support mechanism 42 includes fixed part 421 fixed to the top of spline shaft 41, the both sides of fixed part 421 are hingedly provided with first support rod 6, the end away from fixed part 421 of first support rod 6 is hingedly arranged on the inside of support plate 5.

[0030] During the extension of the spline shaft 41, the spline shaft 41 drives the one end of the first support rod 6 to go up through the fixing member 421. So that the first support rod 6 pushes the two groups of support plates 5 away from each other, until the outer side of the support plate 5 tightly extrudes the inner wall of the transformer body 8, so as to realize the effective fixing of the transformer body 8. Conversely, when the spline shaft 41 is retracted, the spline shaft 41 drives the fixing member 421 to go down. At this time, the fixing member 421 pulls the two groups of support plates 5 to move close to each other through the first support rod 6. With the movement of the support plate 5, the outer side of the support plate 5 and the inner wall of the transformer body 8 are gradually separated, so as to realize the release of the transformer body 8. This mechanism facilitates the disassembly operation of the transformer body 8.

[0031] Referring to Figure 7 As shown in the figure, the end of the second support rod 7 away from the limiting sleeve 32 is hinged to the inner side of the support plate 5 and is at the bottom of the first support rod 6.

[0032] In order to ensure that the support plate 5 remains stable when moving away from each other or moving close to each other, the two ends of the second support rod 7 are connected to the inner side of the support plate 5 and the outside of the limiting sleeve 32 respectively. Specifically, one end of the second support rod 7 is hinged to the inner side of the support plate 5, and the other end is fixed at a proper position outside the limiting sleeve 32. So that the second support rod 7 can provide effective support for the bottom of the support plate 5, and enhance the stability of the support plate 5 during movement.

[0033] Referring to Figure 6 As shown in the figure, the bottom of the feeding round table 3 is provided with a toothed belt 33;

[0034] The driving mechanism 2 comprises a rack 20 fixed to the bottom of the cutting device 1, and the bottom of the rack 20 is provided with a servo motor 21, and the output end of the servo motor 21 is provided with a driving gear 22 capable of engaging with the toothed belt 33.

[0035] When the servo motor 21 drives the driving gear 22 to rotate, the driving gear 22 drives the feeding round table 3 to rotate through the toothed belt 33, so that the feeding round table 3 drives the transformer body 8 at the top to rotate, so as to facilitate the transformer body 8 to complete the encapsulation work.

[0036] Referring to Figure 7 and Figure 8 As shown in the figure, the two sides of the end of the first support rod 6 away from the fixing member 421 are symmetrically provided with the first limiting member 61 for preventing the support plate 5 from deviating, and the end of the first limiting member 61 away from the first support rod 6 is provided with the first ball head 611 capable of always contacting the inner side of the support plate 5.

[0037] In order to enhance the stability of the support plate 5 when moving, a first limiting piece 61 is arranged horizontally at the end of the first support rod 6 away from the fixed part 421. A first ball head 611 capable of contacting the inner side of the support plate 5 is arranged at the end of the first limiting piece 61 away from the first support rod 6. This allows the first limiting piece 61 to effectively support the inner side of the support plate 5 through the first ball head 611, thereby avoiding the support plate 5 from deviating during mutual moving away or moving close to each other.

[0038] As shown in Figure 7 and Figure 8 , the second support rod 7 is symmetrically provided with a second limiting piece 71 on both sides of the end away from the limiting sleeve 32 to prevent the support plate 5 from deviating. The second limiting piece 71 is provided with a second ball head 711 capable of always contacting the inner side of the support plate 5 at the end away from the second support rod 7.

[0039] The second limiting piece 71 is arranged horizontally at the end of the second support rod 7 away from the limiting sleeve 32. The second ball head 711 capable of contacting the inner side of the support plate 5 is installed at the end of the second limiting piece 71 away from the second support rod 7. This design allows the second limiting piece 71 to provide additional support to the inner side of the support plate 5 through the second ball head 711, thereby further reducing the possibility of the support plate 5 deviating when moving away or moving close to each other.

[0040] As shown in Figure 5 , the outer side of the support plate 5 is longitudinally provided with a plurality of raised anti-skid strips 51.

[0041] The anti-skid strips 51 are arranged on the outer side of the support plate 5. When the two groups of support plates 5 move away from each other, the support plate 5 will move together with the anti-skid strips 51 until the anti-skid strips 51 are tightly pressed against the inner wall of the transformer body 8. This ensures that the support plate 5 can be effectively fixed with the transformer body 8, improving the overall stability and safety.

[0042] As shown in Figure 5 , Figure 7 and Figure 8 , the support plate 5 is designed as an arc-shaped structure that can adapt to the inner wall of the transformer body 8.

[0043] In order to improve the adaptability of the support plate 5 to the inner wall of the transformer body 8, the support plate 5 is designed as an arc shape. This allows the support plate 5 to better fit the inner wall of the transformer body 8, thereby enhancing the support effect and improving the overall stability.

[0044] The utility model discloses a transformer body 8 is placed on the top of the material discharging round table 3, and the limiting sleeve 32 is accurately inserted inside the transformer body 8 first when working. Subsequently, through the drive of hydraulic telescopic component 4, the spline shaft 41 moves longitudinally in the limiting sleeve 32. When the spline shaft 41 goes up, the support plate 5 is pushed away from each other through the fixed part 42 and the first support rod 6, and until the support plate 5 is tightly extruded on the inner wall of the transformer body 8, effective fixing is realized. When the transformer body 8 is disassembled, the spline shaft 41 is driven to go down through the hydraulic telescopic component 4, and the support plate 5 is close to each other, and the support plate 5 and the transformer body 8 are separated at this time, thereby facilitating the disassembly of the transformer body 8, in order to ensure the stability of the movement of the support plate 5, the second support rod 7 is connected to the inside of the support plate 5 and the outside of the limiting sleeve 32, and bottom support is provided. Meanwhile, the first limiting part 61 and the second limiting part 71 respectively through the first ball head 611 and the second ball head 711 additional support the inside of the support plate 5, and further reduce the possibility of deviation. Finally, the servo motor 21 drives the driving gear 22 to rotate, and the driving gear 22 drives the material discharging round table 3 and the top transformer body 8 to rotate through the toothed belt 33, and the efficient, stable disassembly and rubber coating operation of the transformer body 8 are realized.
