[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] Refer to Figures 1 - 3 , in an embodiment, a bookbinding machine 100 is provided for bookbinding a composite transformer bushing 20. The composite transformer bushing 20 includes an oil conservator 21, an insulator 22, a flange 23, an in-oil insulating tube 24, and an end base 25 connected in sequence. The oil conservator 21 is fixedly bookbound to the first end 221 of the insulator 22, the second end 222 of the insulator 22 is fixedly bookbound to the first end 231 of the flange 23, the second end 232 of the flange 23 is fixedly bookbound to the first end 241 of the in-oil insulating tube 24, and the second end 242 of the in-oil insulating tube 24 is fixedly bookbound to the end base 25, that is, four bookbinding connection structures are formed on the composite transformer bushing 20. The bookbinding machine 100 includes an electric cylinder device 101, a main body frame 110, a heating device, a support device, and a pressure device. The pressure device is used to apply pressure between the various components of the composite transformer bushing 20 to keep the pressure stable during the bookbinding process, avoid the phenomenon of bias pressure, and apply dynamic pressure during the entire bookbinding process, which can prevent the flatness error caused by the deformation of the heating plate and effectively improve the bookbinding qualification rate. The electric cylinder device 101 is located outside the main body frame 110 and is used to provide power for the bookbinding machine 100.

[0034] For the convenience of description, the length direction of the main frame 110 is defined as the first direction F1, and the width direction of the main frame 110 is defined as the second direction F2. Both the first direction F1 and the second direction F2 are on the same horizontal plane, and the second direction F2 is perpendicular to the first direction F1.

[0035] The heating device includes a first heating device 130, a second heating device 140, and a third heating device 150 that are sequentially and spaced apart along the first direction F1 on the main frame 110. The first heating device 130 and the third heating device 150 are movably arranged on the main frame 110, and the second heating device 140 is fixedly connected to the main frame 110, so that the distance between the first heating device 130 and the second heating device 140 and the distance between the second heating device 140 and the third heating device 150 are adjustable. The support device includes a first support device 160 and a second support device 170 that are movably and sequentially spaced apart along the first direction F1 on the main frame 110. The first support device 160 is located between the first heating device 130 and the second heating device 140 and is used to support the insulator 22; the second support device 170 is located between the second heating device 140 and the third heating device 150 and is used to support the in-oil insulating tube 24.

[0036] The main frame 110 includes a main base 111, a first fixing plate 112, a second fixing plate 113, and a plurality of first guide rods 114. The main base 111 is a metal frame structure and is arranged along the first direction F1 and is used to carry all the devices on the gluing machine 100. The first fixing plate 112 and the second fixing plate 113 are arranged at both ends of the main base 111 along the first direction F1, and the positions of the first fixing plate 112 and the second fixing plate 113 are relatively fixed, which is suitable for gluing the composite transformer bushing 20 within a certain length range. At the same time, the first heating device 130 is arranged close to the first fixing plate 112, and the third heating device 150 is arranged close to the second fixing plate 113. An electric cylinder device 101 and an electrical cabinet (not shown in the figure) are provided on one side of the first fixing plate 112 away from the second fixing plate 113 and are used to provide power support for the first heating device 130. Similarly, an electric cylinder device 101 and an electrical cabinet (not shown in the figure) are also provided on one side of the second fixing plate 113 away from the first fixing plate 112 and are used to provide power support for the third heating device 150.

[0037] The first fixing plate 112 and the second fixing plate 113 are both rectangular plate members, and the first fixing plate 112 and the second fixing plate 113 are fixedly connected by four first guide rods 114, so that the overall main frame 110 is fixed. Among them, the four first guide rods 114 are arranged in a rectangle, that is, the ends of the four first guide rods 114 form the four vertices of a rectangle, so that the positions between the first fixing plate 112 and the second fixing plate 113 are relatively fixed and the connection is more stable. In this embodiment, both ends of the four first guide rods 114 are fixedly connected to the first fixing plate 112 and the second fixing plate 113 respectively, and the four first guide rods 114 are all arranged along the first direction F1. The four first guide rods 114 sequentially penetrate through the first heating device 130, the second heating device 140 and the third heating device 150, and are used to guide the first heating device 130 and the third heating device 150 to move along the first direction F1, ensuring that the axes of the oil conservator 21, the flange 23 and the end base 25 are collinear and parallel to the first direction F1. In other embodiments, the number of the first guide rods is not specifically limited, as long as it can guide the moving direction of the heating device.

[0038] Specifically, the oil conservator 21 is clamped and fixed on the first heating device 130, the insulator 22 is supported on the first support device 160, the flange 23 is clamped and fixed on the second heating device 140, the in-oil insulating tube 24 is supported on the second support device 170, and the end base 25 is clamped and fixed on the third heating device 150, so that each component of the composite transformer bushing 20 is stably supported and the axis of each component is parallel to the first direction F1, while ensuring that each component is coaxially arranged. The pressure device drives the first heating device 130 and the third heating device 150 to move along the first direction F1, and the first heating device 130 and the third heating device 150 move in opposite directions, moving the oil conservator 21 to be fixedly matched with the first end 221 of the insulator 22, moving the end base 25 to be fixedly matched with the second end 242 of the in-oil insulating tube 24, and driving the first support device 160 and the second support device 170 to fixedly match the second end 222 of the insulator 22 with the first end 231 of the flange 23 and the first end 241 of the in-oil insulating tube 24 with the second end 232 of the flange 23; at the same time, the first heating device 130, the second heating device 140, and the third heating device 150 respectively heat the oil conservator 21, the flange 23, and the end base 25 to realize the cementing between each component of the composite transformer bushing 20. Through the movable setting of the first heating device 130 and the third heating device 150, the first heating device 130 and the third heating device 150 can stably clamp the composite transformer bushings 20 with different lengths, so that the cementing machine 100 is applicable to the cementing of composite transformer bushings 20 with different lengths, expanding the use range of the cementing machine 100. Among them, the axis of the composite transformer bushing 20 is parallel to the first direction F1, that is, the length direction of the main frame 110 and the axis of the composite transformer bushing 20 are in the same direction.

[0039] The main body base 111 is a rectangular frame structure made of metal material. The main body base 111 includes two first frames 1111 arranged along the first direction F1. The two first frames 1111 are parallel to each other and spaced apart along the second direction F2. Two second frames 1112 are fixedly connected to the two ends of the two first frames 1111 respectively. The two second frames 1112 are both parallel to the second direction F2. The two first frames 1111 and the two second frames 1112 form a rectangular frame structure. The main body base 111 further includes a cushion base 1113 and a bottom plate 1114. The bottom plate 1114 is located at the bottom end of the main body base 111. The cushion base 1113 is arranged on the bottom plate 1114 and is located below the first frames 1111 and the second frames 1112. The cushion base 1113 can be used to increase the overall height of the first frames 1111 and the second frames 1112, so that the upper top surfaces of the first frames 1111 and the second frames 1112 are higher than the ground. The bottom plate 1114 is used to make the connection between the cushion base 1113 and the first frames 1111 and the second frames 1112 as a whole firm. The first fixing plate 112 and the second fixing plate 113 are respectively fixedly connected to the two second frames 1112. The upper surfaces of the two first frames 1111 and the upper surfaces of the two second frames 1112 are in the same horizontal plane. Among them, the first frames 1111 and the second frames 1112 are both cuboid structural members, the bottom plate 1114 is a flat plate structural member, and the first frames 1111, the second frames 1112, the cushion base 1113 and the bottom plate 1114 as a whole form a box structure.

[0040] There are two first guide rails 115 provided on the main body frame 110. The first guide rails 115 are fixed above the main body base 111 along the first direction F1. Specifically, the two first guide rails 115 are respectively arranged on two first frames 1111, and the first guide rails 115 are located between the first fixing plate 112 and the second fixing plate 113. Both the first heating device 130 and the third heating device 150 are slidably connected to the two first guide rails 115, enabling the first heating device 130 and the third heating device 150 to move along the first direction F1. Moreover, the first heating device 130 moves back and forth between the first fixing plate 112 and the second heating device 140, and the third heating device 150 moves back and forth between the second heating device 140 and the second fixing plate 113. In this embodiment, the two first guide rails 115 are arranged above the main body base 111, which means the position height of the two first guide rails 115 is higher than the upper top surface of the main body base 111, that is, the position height of the two first guide rails 115 is higher than the upper surface of the first frame 1111, such as at positions of one-fourth, one-third, one-half, etc. of the overall height of the first frame 1111, as long as it is not at the bottom of the first frame 1111. In this way, compared with the structure of arranging guide rails at the bottom in traditional bookbinding machines, it can avoid the glue in the flange splashing out and dripping on the guide rails arranged at the bottom during the bookbinding operation, such as when starting to inject glue and when stopping to inject glue, resulting in the first heating device 130 and the third heating device 150 being unable to move smoothly along the first direction F1.

[0041] On the surface of the bottom plate 1114 facing the first frame 1111, there are also two second guide rails 116 extending along the first direction F1. The two second guide rails 116 are arranged at intervals between the two first frames 1111 along the second direction F2. That is, in the second direction F2, the two second guide rails 116 are located between the two first guide rails 115. At the same time, in the first direction F1, the second guide rails 116 are located between the first fixing plate 112 and the second fixing plate 113, and the upper top surface of the second guide rails 116 is lower than the first frame 1111. Both the first support device 160 and the second support device 170 are slidably connected to the two second guide rails 116, enabling the first support device 160 and the second support device 170 to move along the first direction F1. Moreover, the first support device 160 moves back and forth between the first heating device 130 and the second heating device 140, and the second support device 170 moves back and forth between the second heating device 140 and the third heating device 150. Among them, the first support device 160 can be set to one, two, or more, depending on the length requirement of the insulator 22, as long as it can stably support the insulator 22. The second support device 170 can also be set to one, two, or more, and there is no limit here.

[0042] Combined Figure 4 、 Figure 5 and Figure 6As shown, the first heating device 130 is used to heat the conservator 21 so that the conservator 21 is adhesively fixed to the first end 221 of the insulator 22. The first heating device 130 includes a first pressing plate 131. The first pressing plate 131 is a rectangular plate member. The first pressing plate 131 is movably arranged on the first guide rail 115 through a slider and is thus movably connected to the main body frame 110. The first guide rod 114 passes through the first pressing plate 131, enabling the first pressing plate 131 to move along the length direction of the first guide rod 114, i.e., the first direction F1. The first pressing plate 131 is arranged close to the first fixing plate 112, so that the first heating device 130 is arranged close to the first fixing plate 112.

[0043] The first heating device 130 further includes a first heat insulation plate 132, a first heating plate 133, and a first transition plate 134 that are fixedly connected in sequence. They are arranged on one side of the first pressing plate 131 close to the second heating device 140. The first heat insulation plate 132, the first heating plate 133, and the first transition plate 134 are all rectangular plate members. The first heat insulation plate 132, the first heating plate 133, and the first transition plate 134 have the same size and are fixedly connected in sequence to form a heating main body. The first transition plate 134 faces the first support device 160, and the conservator 21 is fixedly connected to the first transition plate 134. Thus, the heating main body can be in direct contact with the conservator 21 for heating. The first heating device 130 further includes a first mounting plate 135. The size of the first mounting plate 135 is slightly larger than that of the first heat insulation plate 132. The heating main body is fixed to the first pressing plate 131 through the first mounting plate 135. Among them, the first heat insulation plate 132 in the heating main body is in contact and fixed with the first mounting plate 135, and the first heating plate 133 is fixedly connected to the conservator 21 through the first transition plate 134. That is, in the first direction F1, the first pressing plate 131, the first mounting plate 135, the first heat insulation plate 132, the first heating plate 133, and the first transition plate 134 are fixedly connected in sequence. Among them, the first heat insulation plate 132 is provided to prevent heat transfer between the first heating plate 133 and the first pressing plate 131, reduce heat loss, and improve heating efficiency. At the same time, by movably connecting the first pressing plate 131 to the main body frame 110 instead of directly movably connecting the first heating plate 133 to the main body frame 110, it is also to prevent the first heating plate 133 from contacting other components and reduce heat loss.

[0044] Since the size of the first mounting plate 135 is slightly larger than that of the first heat insulation plate 133, after the heating body is positioned and fixed to the first mounting plate 135 through pins, the outer edge portion of the first mounting plate 135 protruding from the heating body is fixedly connected to the first pressing plate 131 through the mounting member 136. A rotary pressing cylinder 137 is also fixed on the first pressing plate 131. The fixing portion 1371 of the rotary pressing cylinder 137 is fixedly connected to the first pressing plate 131 to fix the whole rotary pressing cylinder 137; the pressing portion 1372 of the rotary pressing cylinder 137 abuts against the first transition plate 134, thereby pressing and fixing the heating body, fixing the first transition plate 134, the first heating plate 133 and the first heat insulation plate 132. At the same time, pins are sequentially passed through the first transition plate 134, the first heating plate 133, the first heat insulation plate 132, the first mounting plate 135 and the first pressing plate 131 to position and fix between the plate members and prevent deflection. Among them, two rotary pressing cylinders 137 are provided, respectively located at two diagonal corners of the first mounting plate 135 of the rectangular plate member, and the two pressing portions 1372 respectively press two diagonal corners of the first transition plate 134, enhancing the clamping of the first transition plate 134 and making the connection between the heating bodies stable.

[0045] The setting of the rotary pressing cylinder 137 avoids fixing between the first heating plate 133 and the first transition plate 134 through fasteners. Since the first transition plate 134 is adapted to the structure of the oil conservator 21 (see below for details), different composite bushing 20 with different structures have oil conservators 21 with different structures or different sizes. Therefore, the first transition plate 134 needs to be frequently disassembled. If fixed by fasteners, it will cause fastening wear to the first heating plate 133 and the first transition plate 134. The setting of the rotary pressing cylinder 137 does not require fixing by fasteners, and only needs to position the first heating plate 133 and the first transition plate 134 through pins, which is convenient to operate and improves the service life of the first heating device 130.

[0046] Among them, a heating pipe is arranged in the first heating plate 133 for heating the oil conservator 21 during the potting process. In this embodiment, the heating pipe in the first heating plate 133 is a resistive heating pipe, which has high heating efficiency, automatic temperature control, and is convenient for installation and maintenance. In other embodiments, other types of heating pipes can be set as long as the temperature required for potting the oil conservator can be achieved, and no limitation is made here.

[0047] Continue to combine Figure 7, the first transition plate 134 includes a transition plate body 1341 and a convex block 1342. The transition plate body 1341 is directly in contact with and fixed to the first heating plate 133. The convex block 1342 is disposed on a side of the transition plate body 1341 away from the first heating plate 133. A plurality of mounting holes (not shown in the figure) are provided on the transition plate body 1341. The plurality of mounting holes are arranged along the circumferential direction of the convex block 1342 and are located outside the convex block 1342. After the oil storage tank 21 is sleeved on the outer circumference of the convex block 1342, the end face of the oil storage tank 21 is matched with the mounting holes on the transition plate body 1341 and is fixed by fasteners, so that the oil storage tank 21 is fixed on the first transition plate 134. The convex block 1342 is a disc member. The oil storage tank 21 is sleeved on the outer circumference of the convex block 1342, and the size of the convex block 1342 is matched with the inner diameter size of the oil storage tank 21. The outer circumference of the convex block 1342 abuts against the inner wall of the oil storage tank 21, enabling the oil storage tank 21 to be accurately positioned and not easily offset during the force application process of the adhesive bonding. At the same time, two symmetric notches 1343 are further provided at the lower end of the first transition plate 134 for passing through pins to position and fix the first transition plate 134.

[0048] Continue to refer to Figure 5 , a heating wire box 102 is further provided on the first pressing plate 131. The heating wire box 102 is disposed on the first pressing plate 131 and is located above the first heat insulation plate 132 and the first heating plate 133. The heating wire box 102 is of a cuboid structure. The heating wire box 102 is used to place heating pipelines and plays a protective role. Among them, the heating wire box 102 can be made of a metal material or an insulating material to better achieve the heat insulation effect and avoid the over-high temperature of the heating pipelines.

[0049] A first temperature measuring device 138 is further provided on the first pressing plate 131. The first temperature measuring device 138 is disposed on the first pressing plate 131. The first temperature measuring device 138 can monitor the temperature of the surface of the oil storage tank 21. When the temperature fails to reach the temperature required for adhesive bonding, the first heating plate 133 is controlled by the electrical cabinet to continuously increase the temperature. When the temperature exceeds the set temperature, the first heating plate 133 is controlled to immediately stop heating, eliminating the need for manual monitoring and saving labor costs. In this embodiment, the first temperature measuring device 138 is an infrared temperature measuring sleeve head, which uses non-contact temperature measurement, does not affect the adhesive bonding state of the oil storage tank 21, and has the advantages of a wide measurement range, fast temperature measurement speed, high accuracy, and high sensitivity. In other embodiments, the temperature sensor can also be other types of sensors, such as contact temperature sensors such as thermocouples and thermistors, as long as it can monitor the adhesive bonding temperature of the oil storage tank in real time and accurately, and can also be set at other positions as long as it can monitor the temperature, and no specific limitations are made here.

[0050] A first pressing plate 131 is further provided with a first glue receiving groove 139. The first glue receiving groove 139 is fixed on the first pressing plate 131, located below the first heating plate 133 and extends to the outside of the first heating plate 133 along the first direction F1, so that the first glue receiving groove 139 can be used to receive the glue overflowed from the oil conservator 21. It can ensure that the first glue receiving groove 139 can move synchronously with the first pressing plate 131 along the first direction F1 and is always located below the first heating plate 133. That is, when the oil conservator 21 is fixed on the first heating plate 133 for gluing with the insulator 22, the first glue receiving groove 139 is always located below the oil conservator 21 to timely receive the glue overflowed from the oil conservator 21 and avoid the difficulty of cleaning the glue dropped on the ground.

[0051] Combined Figure 4 、 Figure 8 and Figure 9 As shown, a prolonging device 180 is also connected to the side of the first heating device 130 away from the first supporting device 160. The prolonging device 180 includes a first connecting plate 181, a second connecting plate 182 and a plurality of prolonging members 183. The first connecting plate 181 is arranged on the side of the first pressing plate 131 away from the first supporting device 160. After the first connecting plate 181 is closely attached to the first pressing plate 131, it is slidably connected to the first guide rail 115 through the same slider as the first pressing plate 131. The second connecting plate 182 is arranged at an interval from the first connecting plate 181 along the first direction F1 and is located on the side of the first connecting plate 181 away from the first pressing plate 131. At the same time, the first connecting plate 181 and the second connecting plate 182 are fixedly connected through the prolonging members 183. The second connecting plate 182 is also slidably connected to the first guide rail 115 through a slider. The first guide rod 114 sequentially passes through the first pressing plate 131, the first connecting plate 181 and the second connecting plate 182, so that the prolonging device 180 moves along the first direction F1 on the first guide rail 115 together with the first heating device 130. After the first guide rod 114 sequentially passes through the first pressing plate 131, the first connecting plate 181 and the second connecting plate 182, one end of the first guide rod 114 is fixed to the first fixing plate 112. Among them, both the first connecting plate 181 and the second connecting plate 182 are rectangular plate members, and the length and width of the first connecting plate 181 and the second connecting plate 182 are the same as those of the first pressing plate 131, which is convenient for the overall movement of the prolonging device 180.

[0052] Specifically, the extension member 183 includes an extension cylinder 1831 and two connecting plates 1832. The extension cylinder 1831 is a hollow columnar structure, and the two connecting plates 1832 are respectively fixedly connected to both ends of the extension cylinder 1831. The extension member 183 is adjustably clamped between the first connecting plate 181 and the second connecting plate 182 through the connecting plates 1832. The extension cylinder 1831 is set as a hollow columnar structure, which can overall reduce the weight and manufacturing cost of the extension member 183. Of course, the extension cylinder can also be set as a solid structure, which is not limited herein. On the side plate surface of the first connecting plate 181 away from the first pressing plate 131, there is an installation block 1811. The installation block 1811 is a U-shaped block, with one end closed and the other end open. The cross-section of its open end is two L-shapes with opposite openings. The distance between the closest ends of the two L-shaped long sides (the sides extending along the second direction F2) is matched with the outer diameter of the extension cylinder 1831, the distance between the two L-shaped short sides (the sides extending along the first direction F1) is matched with the outer diameter of the connecting plate 1832, and the distance between the two L-shaped long sides and the plate surface of the first connecting plate 181 is matched with the thickness of the connecting plate 1832. Similarly, on the side of the second connecting plate 182 close to the first connecting plate 181, there is also the same installation block 1811, which will not be elaborated herein. Therefore, a stepped accommodation cavity is formed between the installation block 1811 and the first connecting plate 181, and between the installation block 1811 and the second connecting plate 182. The extension member 183 is respectively clamped in the stepped accommodation cavities of the first connecting plate 181 and the second connecting plate 182 through the two connecting plates 1832, so that the positions between the first connecting plate 181 and the second connecting plate 182 are relatively fixed. Among them, the length of the extension cylinder 1831 along the first direction F1 is designed according to specific requirements.

[0053] Since the second heating device 140 is fixedly connected to the main body frame 110, the positions between the first fixing plate 112 and the second heating device 140 are relatively fixed. For composite transformer bushings 20 of different lengths, the lengths of their insulators 22 are also different. By adding an extension device 180 between the first heating device 130 and the first fixing plate 112 and adjusting the length of the extension cylinder 1831, the distance between the first heating device 130 and the first fixing plate 112 can be adjusted, so as to be applicable to composite transformer bushings 20 of various lengths. Among them, an extension piece 183 can be provided between the first heating device 130 and the first fixing plate 112, or multiple extension pieces 183 can be provided. The multiple extension pieces 183 are fixedly connected to each other through a connection plate 1832, which will not be elaborated here. Through the matching setting of multiple extension pieces 183, the extension cylinder 1831 can be designed into multiple small-size specifications, and multiple small-size extension pieces 183 are spliced to adapt to composite transformer bushings 20 of various sizes, which can avoid designing large-size extension pieces 183 of various different lengths, that is, a certain number of extension pieces 183 can be spliced into composite transformer bushings 20 of various specifications, thereby reducing the manufacturing cost of the extension device 180.

[0054] Continue to refer to Figure 1 、 Figure 2 and Figure 4 , the pressure device for driving the first heating device 130 is the first pressure device 121. The first pressure device 121 is arranged between the first fixing plate 112 and the extension device 180, specifically on the side of the second connecting plate 182 away from the first connecting plate 181. The first pressure device 121 applies pressure directly to the extension device 180, and then applies pressure to the entire first heating device 130, and further applies a cementing pressure to the conservator 21 clamped on the first heating device 130, so that the conservator 21 is in close contact with the insulator 22, thereby ensuring that the mating position when the conservator 21 is sleeved on the outer periphery of the insulator 22 meets the design requirements of the composite transformer bushing 20 and guaranteeing the cementing quality.

[0055] Combined with Figure 10 , the first pressure device 121 includes a driving rod 1211, a pressing head 1212 and a pressure sensor 1213. The driving rod 1211 drives the pressing head 1212 to move the first heating device 130 along the first direction F1 and provides a cementing pressure during the cementing process. The pressure of the first pressure device 121 is adjustable within the range of 0.5 - 5T to meet the cementing requirements of different types of composite transformer bushings.

[0056] Among them, the driving rod 1211 has a long rod-shaped structure. The cross-section of one end of the driving rod 1211 close to the pressing head 1212 is circular, which is convenient for connecting with the pressing head 1212. The cross-section of the other end is a curved-edge rectangle, that is, one pair of opposite sides is straight and the other pair of opposite sides is arc-shaped, which is convenient for the reliable connection between the driving rod 1211 and the electric cylinder device 101 without slipping. The pressing head 1212 has a cylindrical structure. A connecting block 12111 is provided at the end of the driving rod 1211 in contact with the pressing head 1212 for the fixed connection between the driving rod 1211 and the pressing head 1212. The connecting block 12111 has a cylindrical structure, and the diameter of the cross-section of the connecting block 12111 is larger than the diameter of the cross-section of one end of the driving rod 1211 close to the pressing head 1212. In other embodiments, the shapes of the driving rod and the connecting block can also be other shapes, such as the driving rod has a prismatic structure and the connecting block has a cuboid structure, which is not specifically limited here and shall be subject to actual requirements.

[0057] The pressure sensor 1213 is arranged between the pressing head 1212 and the pressure plate 1214. Specifically, the first pressure device 121 further includes a pressure plate 1214. The pressure plate 1214 is a rectangular plate member. The first pressure device 121 is connected to the second connecting plate 182 through the pressure plate 1214. The cross-section of the pressure plate 1214 is larger than the cross-section of the pressing head 1212. Conducting pressure through the pressure plate 1214 can ensure the balance, stability and continuity of pressure during the gluing process. The pressure sensor 1213 is arranged between the pressing head 1212 and the pressure plate 1214, and can accurately sense the pressure between the first pressure device 121 and the second connecting plate 182. In this embodiment, the accuracy of the pressure sensor 1213 is 100N, and it can cooperate with the driving rod 1211 to sense and adjust the gluing pressure applied to the first pressure device 121. That is, when the pressure detected by the pressure sensor 1213 does not reach the required gluing pressure, a signal is transmitted to the electrical cabinet, and then the driving rod 1211 is controlled to drive the pressing head 1212 to continuously apply pressure to the first heating device 130, so that the first heating device 130 moves along the first direction F1 towards the second fixing plate 113 until the pressure detected by the pressure sensor 1213 reaches the required gluing pressure; when the pressure exceeds the required gluing pressure, the driving rod 1211 immediately stops pressurizing and relieves the pressure to the required pressure, thereby ensuring the stability of the pressure during the entire gluing process, eliminating the flatness error between the oil storage tank 21 and the insulator 22 caused by the deformation of the heating plate during the gluing process after the existing gluer applies pressure once, and there is no need for manual monitoring, saving labor costs. In other embodiments, the accuracy of the pressure sensor can also be other types, as long as it can meet the gluing requirements of the composite transformer bushing.

[0058] The first pressure device 121 further includes a locking block 1215. The locking block 1215 is a U-shaped block with one end closed and the other end open. The cross-section of its open end is two L-shapes with opposite openings. The distance between the two long sides of the L-shapes (the sides extending along the first direction F1) is the same as the diameter of the cross-section of the connecting block 12111. The distance between the closest ends of the two short sides of the L-shapes (the sides extending along the second direction F2) is the same as the diameter of the cross-section of the end of the driving rod 1211 near the pressing head 1212. When the locking block 1215 is fixed to the pressing head 1212, a stepped accommodation cavity is formed between the locking block 1215 and the pressing head 1212, and the driving rod 1211 and the connecting block 12111 are exactly clamped in the stepped accommodation cavity. During assembly, first fixedly connect the locking block 1215 and the pressing head 1212, then clamp the connecting block 12111 in the stepped accommodation cavity for convenient positioning, and then fixedly connect the connecting block 12111 and the pressing head 1212 to achieve the fixed connection between the driving rod 1211 and the pressing head 1212. Further, since a stepped accommodation cavity is formed between the locking block 1215 and the pressing head 1212, the connecting block 12111 can also be directly clamped in the stepped accommodation cavity, and the fixed connection between the driving rod 1211 and the pressing head 1212 can be achieved without further fixation.

[0059] Among them, the driving rod 1211 is driven by a servo motor. Through the servo motor, the telescopic distance of the driving rod 1211 can be accurately controlled. Cooperating with the pressing head 1212, the pressure plate 1214, and the pressure sensor 1213, the first heating device 130 can be accurately pressed to provide a stable gluing pressure. In other embodiments, the pressure device can be driven by other types of motors or other driving devices, as long as it can clamp the composite insulator by the first heating device and the second heating device and maintain a stable gluing pressure.

[0060] In this embodiment, the locking block 1215 and the pressing head 1212, the pressing head 1212 and the pressure plate 1214, and the pressure plate 1214 and the first heating device 130 are all fixedly connected by bolts. In other embodiments, the locking block and the pressing head, the pressing head and the pressure plate, and the pressure plate and the first heating device can also be fixedly connected by clamping, welding and other connection methods. The locking block can also be not provided, and the connecting block is directly fixedly connected to the pressing head, as long as their respective functions can be achieved, and no specific limitation is made here. In other embodiments, the components of the pressure device can also be other structures, such as triangular prisms, pentagonal prisms, etc., as long as they can cooperate with each other to achieve the function of the pressure device, and no specific limitation is made here.

[0061] Refer to Figure 1 、 Figure 11 and Figure 12, the second heating device 140 includes a second pressing plate 141. The second pressing plate 141 is of a frame structure. The second pressing plate 141 includes a lower end portion 1411, two side portions 1412 and a U-shaped portion 1413. The lower end portion 1411 is a rectangular frame plate. The lower end portion 1411 is fixedly connected to the main frame 110 along the second direction F2, so that the distances between the second heating device 140 and the first fixing plate 112, and between the second heating device 140 and the second fixing plate 113 are fixed. The two side portions 1412 are respectively arranged at both ends of the lower end portion 1411 in the second direction F2, and the side portions 1412 extend in the vertical direction. The two side portions 1412 are both rectangular frame plates. The U-shaped portion 1413 is a plate member with a U-shaped opening structure, and the outside of the U-shaped portion is fixedly connected to the lower end portion 1411 and the two side portions 1412 at the same time, so that the U-shaped opening is arranged upward for accommodating the heating body and the flange 23 of the second heating device 140.

[0062] The heating body of the second heating device 140 includes a second heat insulation plate 142, a second heating plate 143 and a second transition plate 144 which are fixedly connected in sequence. The second heat insulation plate 142, the second heating plate 143 and the second transition plate 144 are all plate members with U-shaped openings. The second pressing plate 141 is also of a U-shaped opening structure, and the U-shaped opening sizes of the second heat insulation plate 142 and the second pressing plate 141 are the same. The second heat insulation plate 142 is fixedly arranged on the plate surface of the second pressing plate 141 close to the first heating device 130. Then, the second transition plate 144 faces the first support device 160 to directly contact the insulator 22 of the composite transformer bushing 20 for heating. The specific structures and functions of the second heat insulation plate 142, the second heating plate 143 and the second transition plate 144 are similar to those of the first heat insulation plate 132, the first heating plate 133 and the first transition plate 134 respectively, and will not be elaborated here.

[0063] The U-shaped opening sizes of the second heating plate 143 and the second transition plate 144 are the same and smaller than the U-shaped opening size of the second heat insulation plate 142, and the sizes of the second heating plate 143 and the second transition plate 144 match the outer diameter of the second end 232 of the flange 23 for fixing the flange 23. Among them, the flange plate of the flange 23 is fixedly connected to the second transition plate 144 closely. The second end 232 of the flange 23 is clamped in the U-shaped opening and faces the third heating device 150 for being glued and fixed to the oil-insulated pipe 24. The first end 231 of the flange 23 faces the first heating device 130 for being glued and fixed to the insulator 22.

[0064] A rotary pressing cylinder 145 is also fixed on the second pressing plate 141. The rotary pressing cylinder 145 is used to press the heating body of the second heating device 140, which is specifically similar to the aforementioned rotary pressing cylinder 137 and will not be elaborated here. Meanwhile, a second glue receiving groove 146 is also provided on the second pressing plate 141. The second glue receiving groove 146 is fixed on the U-shaped portion 1413, located below the second heating plate 143 and extends along the first direction F1 to the outside of the second heating plate 143, so that the second glue receiving groove 146 can be used to receive the glue overflowing from the flange 23, which is specifically the same as the structure and function of the aforementioned first glue receiving groove 139 and will not be elaborated here. In addition, a second temperature measuring device 147 is further provided on the second pressing plate 141. The second temperature measuring device 147 is arranged on the second pressing plate 141 and is used to monitor the temperature of the surface of the flange 23, which is specifically the same as the structure and function of the aforementioned first temperature measuring device 138 and will not be elaborated here.

[0065] Refer to Figure 1 、 Figure 2 and Figure 11 , the third heating device 150 includes a third pressing plate 151, a third heat insulation plate 152, a third heating plate 153 and a third transition plate 154 that are fixedly connected in sequence. The third transition plate 154 faces the second heating device 140 and is in direct contact with the flange 23 of the composite transformer bushing 20 for heating. The third heat insulation plate 152, the third heating plate 153 and the third transition plate 154 are all rectangular plate members, and their lengths and widths are the same and are fixedly connected in sequence to form a heating body. The third heating device 150 also includes a third mounting plate 155. The third mounting plate 155 is fixedly connected to the plate surface of the third pressing plate 151 close to the second heating device 140, which is specifically the same as the aforementioned first mounting plate 135 and will not be elaborated here.

[0066] A number of equal-height columns 156 are also provided between the third mounting plate 155 and the heating body. The two ends of the equal-height columns 156 are respectively connected to the heating body and the third mounting plate 155 and are arranged along the first direction F1. The number of equal-height columns 156 is distributed at intervals along the second direction F2, so that the heating body of the third heating device 150 extends along the first direction F1 to the outside of the third pressing plate 151, which is used to adjust the distance between the third heating device 150 and the second heating device 140. By setting equal-height columns 156 with different length specifications, it is applicable to oil-insulated pipes 24 with various length specifications. Among them, a third connecting plate 157 is connected to the heating body and is used for fixedly connecting with the equal-height columns 156 to prevent the equal-height columns 156 from directly contacting and connecting the third heat insulation plate 152.

[0067] In other embodiments, the third heating device may also be set to have the same structure as the first heating device 130; alternatively, the first heating device may also be set to have the same structure as the third heating device 150, that is, the first heating device further includes equal-height columns. A fourth connecting plate is fixedly connected to the side of the first heat insulation plate away from the first heating plate. The equal-height columns are fixedly connected between the first pressing plate and the fourth connecting plate, and are adjusted in various ways to adapt to insulators of different length specifications, which will not be limited herein.

[0068] Since the second heating device 140 is fixedly connected to the main body frame 110, the positions between the second heating device 140 and the second fixing plate 113 are relatively fixed. For composite transformer bushings 20 of different lengths, the lengths of the oil-insulated tubes 24 therein are also different. Therefore, an extension device may be additionally provided between the third heating device 150 and the second fixing plate 113 to further adjust the distance between the third heating device 150 and the second heating device 140, so as to be applicable to composite transformer bushings of various lengths. The extension device may be provided as one or more, which is the same as the foregoing specifically and will not be elaborated.

[0069] Continue to refer to Figure 2 ., a second pressure device 122 is further provided between the extension device and the second fixing plate 113. The structure and installation position of the second pressure device 122 are similar to those of the first pressure device 121, which will not be elaborated specifically. The second pressure device 122 is used to apply pressure to the entire third heating device 150, and further apply caulking pressure to the end base 25 clamped on the third heating device 150, so that the end base 25 is in close contact with the oil-insulated tube 24, thereby ensuring that the mating position when the end base 25 is sleeved on the outer periphery of the oil-insulated tube 24 meets the design requirements of the composite transformer bushing 20 and guaranteeing the caulking quality.

[0070] Refer to Figure 1 and Figure 14 ., the first supporting device 160 is arranged between the first heating device 130 and the second heating device 140 and is used to support the insulator 22, so that the two ends of the insulator 22 are respectively sleeved and fixed with the oil conservator 21 and the flange 23. The first supporting device 160 includes a first bracket 161, a first moving bracket 162, a second moving bracket 163 and a first supporting portion 164. Among them, the first bracket 161 is slidably connected to the main body frame 110. Specifically, the first bracket 161 is slidably connected to two second guide rails 116 through sliders, so that the first supporting device 160 is movably arranged on the main body frame 110 along the first direction F1, and the first supporting device 160 moves back and forth between the first heating device 130 and the second heating device 140.

[0071] The first moving bracket 162 is movably arranged on the first bracket 161 along the second direction F2, and the second moving bracket 163 is movably arranged on the first moving bracket 162 along the vertical direction. Among them, a vertically arranged first guide frame 167 is fixedly connected to the first moving bracket 162, and the second moving bracket 163 is slidably connected to the first guide frame 167, so that the second moving bracket 163 can move back and forth along the vertical direction. Specifically, the first supporting device 160 further includes a first handwheel 165 and a second handwheel 166. By rotating the first handwheel 165, the first moving bracket 162 can be controlled to move along the second direction F2, and by rotating the second handwheel 166, the second moving bracket 163 can be controlled to move up and down along the vertical direction. By controlling the movement of the insulator 22 along the second direction F2 and the vertical direction through the first moving bracket 162 and the second moving bracket 163, on the one hand, it is convenient to adjust the concentricity between the insulator 22 placed on the first supporting device 160 and the conservator 21 fixed on the first heating device 130, ensuring the smooth subsequent cementing; on the other hand, it is convenient for the hoisting of the composite transformer bushing 20. By adjusting the distance between the composite transformer bushing 20 and each component of the cementing machine 100, the composite transformer bushing 20 can be prevented from being damaged due to collision during the hoisting and transportation process. Since the first supporting device 160 mainly functions to support the insulator 22, its movement along the first direction F1 can be roughly adjusted manually, that is, manually push the first supporting device 160 to slide along the two second guide rails 116, as long as it can stably support the composite transformer bushing 20. In other embodiments, a servo motor can also be provided to control the movement of the first moving bracket along the second direction, the second moving bracket along the vertical direction, and the first supporting device along the first direction, realizing automatic operation and accurately controlling the moving distance.

[0072] The first supporting part 164 is located on the second moving bracket 163. The first supporting part 164 is a V-shaped plate. Since the insulator 22 is usually a cylindrical structure, the V-shaped opening of the first supporting part 164 can hold the insulator 22 when it is placed on the first supporting part 164, and it is not easy to roll and slip. Since the first supporting part 164 is in direct contact with the insulator 22, in order to avoid damaging the silicone rubber umbrella skirt on the surface of the insulator 22, the contact part of the first supporting part 164 with the composite transformer bushing 20 is made of nylon material. The nylon material has high mechanical strength, good toughness, smooth surface, and small friction coefficient, and will not damage the surface of the composite transformer bushing 20. In other embodiments, the contact part of the first supporting part with the composite transformer bushing can be made of other materials, as long as it can ensure that its surface is smooth and will not damage the surface of the composite transformer bushing.

[0073] In this embodiment, the number of the first support devices 160 is two, and the two first support devices 160 are arranged on the main body frame 110 at intervals along the first direction F1, which can more stably support the composite transformer bushing 20 and avoid the phenomenon of unstable force when there is only one first support device 160 and it is not in the exact middle of the composite transformer bushing 20, resulting in the inclination and dropping of the composite transformer bushing 20. In other embodiments, the number of the first support devices is not limited, as long as it can support the composite transformer bushing to keep it balanced.

[0074] Refer to Figure 1 and Figure 15 , the second support device 170 is arranged between the second heating device 140 and the third heating device 150 and is used to support the in-oil insulating tube 24, so that the two ends of the in-oil insulating tube 24 are respectively sleeved and fixed with the flange 23 and the end base 25. The second support device 170 includes a second bracket 171, a third moving bracket 172, a fourth moving bracket 173, a second support portion 174 and a second guide frame 177. Among them, the second bracket 171 is slidably connected to the main body frame 110. Specifically, the second bracket 171 is slidably connected to the two second guide rails 116 through sliders, so that the second support device 170 is movably arranged on the main body frame 110 along the first direction F1, and the second support device 170 moves back and forth between the second heating device 140 and the third heating device 150. The structures and connection methods of the second bracket 171 and the aforementioned first bracket 161, the third moving bracket 172 and the aforementioned first moving bracket 162, the fourth moving bracket 173 and the aforementioned second moving bracket 163, and the second guide frame 177 and the aforementioned first guide frame 167 are all the same, that is, the third moving bracket 172 is movably arranged on the second bracket 171 along the second direction F2, and the fourth moving bracket 173 is movably arranged on the third moving bracket 172 along the vertical direction, which will not be elaborated here. At the same time, the second support device 170 also includes a handwheel to control the movement of the third moving bracket 172 along the second direction F2 and the fourth moving bracket 173 along the vertical direction, which will not be elaborated here either.

[0075] The second support part 174 is movably arranged on the fourth moving bracket 173. The second support part 174 is a clamping structure, and the second support part 174 includes two oppositely arranged clamping parts 1741. The clamping parts 1741 are of a V-shaped opening structure. Since the in-oil insulating pipe 24 is usually a columnar structure, the V-shaped openings of the two clamping parts 1741 centrally clamp the outer periphery of the in-oil insulating pipe 24 and can clamp the in-oil insulating pipe 24 tightly, and it is not easy to roll and cause slipping. The two clamping parts 1741 are movably arranged at the top of the fourth moving bracket 173. An automatic clamping structure 1742 is arranged on the second support part 174, so that the two clamping parts 1741 can move back and forth along the second direction F2. When it is necessary to clamp the in-oil insulating pipe 24, operate the automatic clamping structure 1742 to move the two clamping parts 1741 in a direction away from each other, and then place the in-oil insulating pipe 24. After the in-oil insulating pipe 24 is stable, operate the automatic clamping structure 1742 again to move the two clamping parts 1741 in a direction close to each other to centrally clamp the in-oil insulating pipe 24.

[0076] Wherein, the contact part of the second support part 174 with the in-oil insulating pipe 24 is made of nylon. The nylon material has high mechanical strength, good toughness, smooth surface and small friction coefficient, and will not damage the surface of the composite transformer bushing 20. In other embodiments, the contact part of the second support part with the composite transformer bushing can be made of other materials, as long as it can ensure that its surface is smooth and will not damage the surface of the composite transformer bushing.

[0077] In other embodiments, the second support device can also be set to have the same structure as the first support device 160, which is not limited herein.

[0078] The working process of the gluing machine 100 is as follows: Fix the oil conservator 21 to the first heating device 130, the flange 23 to the second heating device 140, and the end base 25 to the third heating device 150. Horizontally place the insulator 22 on the first supporting device 160 and the in-oil insulating tube 24 on the second supporting device 170. Control the movement of the insulator 22 through the first moving bracket 162 and the second moving bracket 163 to make the oil conservator 21, the insulator 22, and the flange 23 coaxial, and control the movement of the in-oil insulating tube 24 by moving the third moving bracket 172 and the fourth moving bracket 173 to make the in-oil insulating tube 24 and the end base 25 both coaxial with the flange 23, that is, all components of the composite transformer bushing 20 are coaxial. At the same time, drive the first heating device 130 to move along the length direction of the main frame 110 by the first pressure device 121 and drive the third heating device 150 to move along the length direction of the main frame 110 by the second pressure device 122 until both ends of the insulator 22 are respectively sleeved in the oil conservator 21 and the flange 23 and clamped, and both ends of the in-oil insulating tube 24 are respectively sleeved in the flange 23 and the end base 25 and clamped, realizing the fitting and installation of the oil conservator 21, the flange 23 and the insulator 22 and the fitting and installation of the flange 23, the end base 25 and the in-oil insulating tube 24 and maintaining the required gluing pressure. Inject glue into the glue injection holes of the oil conservator 21, the flange 23 and the end base 25 respectively, and heat the first heating device 130, the second heating device 140 and the third heating device 150 to the required gluing temperature to cure the glue and realize the gluing of the composite transformer bushing 20.

[0079] The beneficial effects of this application are as follows: Different from the prior art, the gluing machine of this application includes a main frame, a first heating device, a second heating device, a third heating device, a first supporting device, a second supporting device and a pressure device, which can simultaneously glue all components of the composite transformer bushing, realizing the horizontal gluing process of the composite transformer bushing, that is, gluing four parts at one time. And by setting the pressure device, the gluing pressure can be kept stable, avoiding the phenomenon of bias pressure. Moreover, dynamic pressure is applied during the whole gluing process, which can prevent the flatness error caused by the thermal deformation of the heating plate during the gluing process, effectively improving the product qualification rate, and is convenient to operate and has high production efficiency.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of this application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of this application by the same token.
