Description

Technical Field

[0001] This application relates to the technical field of the manufacture of composite insulators, and particularly to a cementing machine. Background Art

[0002] Cementing is one of the most widely used assembly forms for composite insulator products. It mainly utilizes the gelling or solidifying characteristics of the cementing agent to fill the gap reserved between the glass fiber tube and the flange, connecting the two and forming an assembly technology for products that meet the mechanical and electrical property requirements.

[0003] The existing cementing of composite insulators generally adopts vertical cementing. Vertical cementing requires cementing the flanges at both ends of the composite insulator sequentially, resulting in low production efficiency and a relatively low first-pass rate of the products. The existing horizontal cementing is currently only applicable to the structure where both ends of the composite insulator are flanges. For the structure of the composite insulator with a hollow and conductive rod, the existing horizontal cementing machine cannot achieve the cementing effect. Therefore, a cementing machine with a new structure needs to be proposed. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of this application is to provide a cementing machine. This cementing machine adopts a horizontal cementing process, which can simultaneously cement the flanges at both ends of a composite insulator with a hollow and conductive rod. By setting a pressure device, the cementing pressure can be kept stable to avoid the phenomenon of bias pressure.

[0028] 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.

[0029] Refer to Figures 1 - 2, in one embodiment, a bookbinding machine 100 is provided for bookbinding a composite insulator 20. The composite insulator 20 includes an insulator 21, a first flange 22 located at one end of the insulator 21, a second flange 23 located at the other end of the insulator 21, and a conductive rod 24 passing through the inner cavity of the insulator 21. One end of the conductive rod 24 is fixedly connected to the second flange 23, and the other end passes through the inner cavity of the insulator 21 and extends out of the insulator 21 from the first flange 22. The bookbinding machine 100 includes an electric cylinder device 101, a main body frame 110, a first heating device 120, a second heating device 130, a first support device 140, a second support device 150, and a pressure device 160. The pressure device 160 is used to apply pressure to the composite insulator 20 to keep the pressure stable during the bookbinding process, avoid the phenomenon of bias voltage, and perform dynamic pressure application 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. The first heating device 120, the first support device 140, and the second heating device 130 are sequentially and movably arranged at intervals along the length direction of the main body frame 110 on the main body frame 110. The second support device 150 is fixedly connected to the main body frame 110 and is located between the first support device 140 and the second heating device 130. Among them, the first support device 140 is located between the first heating device 120 and the second heating device 130 and is used to support the insulator 21; the second support device 150 is located between the first support device 140 and the second heating device 130 and is used to support the conductive rod 24.

[0030] For the convenience of description, the length direction of the main body frame 110 is defined as the first direction F1, and the width direction of the main body frame 110 is defined as the second direction F2. Both the first direction F1 and the second direction F2 are located on the same horizontal plane, and the second direction F2 is perpendicular to the first direction F1.

[0031] The main body frame 110 includes a base 111, an electric cylinder connecting plate 112, a fixing plate 113, and several first guide rods 114. The base 111 is a metal frame structure arranged along the first direction F1 and is used to carry all the devices on the gluing machine 100. The electric cylinder connecting plate 112 is fixedly connected to the edge of one end of the base 111. Both the electric cylinder device 101 and the electrical cabinet 102 are connected to the side of the electric cylinder connecting plate 112 away from the base 111 and are used to provide power support for the gluing machine 100. The fixing plate 113 is fixedly connected to the base 111 and is spaced from the electric cylinder connecting plate 112 in the first direction F1. The positions between the electric cylinder connecting plate 112 and the fixing plate 113 are relatively fixed, which is suitable for gluing the composite insulator 20 within a certain length range. In this embodiment, both the electric cylinder connecting plate 112 and the fixing plate 113 are rectangular plate members, and the electric cylinder connecting plate 112 and the fixing plate 113 are fixedly connected by four first guide rods 114 to make the whole main body frame 110 fixed. Among them, the four first guide rods 114 are distributed in a rectangle, that is, the ends of the four first guide rods 114 form the four vertices of a rectangle, making the positions between the electric cylinder connecting plate 112 and the fixing plate 113 relatively fixed and the connection more stable. In this embodiment, both ends of the four first guide rods 114 are fixedly connected to the electric cylinder connecting plate 112 and the 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 penetrate through the first heating device 120 to make the first heating device 120 located between the electric cylinder connecting plate 112 and the fixing plate 113. The first guide rods 114 are used to guide the first heating device 120 to move along the first direction F1 to ensure that the axis of the first flange 22 is 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.

[0032] Specifically, the first flange 22 is clamped and fixed on the first heating device 120, the insulator 21 of the composite insulator 20 is supported on the first supporting device 140, the second flange 23 is clamped and fixed on the second heating device 130, a conducting rod 24 is fixedly connected to one end of the second flange 23 close to the insulator 21, and the conducting rod 24 is supported on the second supporting device 150, so that the second flange 23 and the conducting rod 24 are stably supported and the length direction of the conducting rod 24 is parallel to the first direction F1, that is, the first flange 22, the second flange 23, the conducting rod 24 and the insulator 21 are coaxial. The pressing device 160 drives the first heating device 120 and the second heating device 130 to move along the first direction F1, moves the first flange 22 to be assembled and fixed with one end of the insulator 21, moves the second flange 23 to be assembled and fixed with the other end of the insulator 21, the first heating device 120 and the second heating device 130 respectively clamp and fix the first flange 22 and the second flange 23 at both ends of the insulator 21, and at the same time, the first heating device 120 and the second heating device 130 respectively heat the first flange 22 and the second flange 23 to realize the potting of the composite insulator 20. Through the movable arrangement of the first heating device 120 and the second heating device 130, the first heating device 120 and the second heating device 130 can stably clamp composite insulators of different lengths, so that the potting machine 100 can be applicable to the potting of composite insulators of different lengths, and the use range of the potting machine 100 is expanded. Wherein, the axial direction of the composite insulator 20 is parallel to the first direction F1, that is, the length direction of the main body frame 110 and the axial direction of the composite insulator 20 are in the same direction.

[0033] The base 111 is a rectangular frame structure made of metal material. The 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 both 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 the base 111 of the rectangular frame structure. The electric cylinder connecting plate 112 is fixedly connected to one of the second frames 1112. Wherein, 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.

[0034] There are two first guide rails 115 provided on the main body frame 110. The first guide rails 115 are fixed above the base 111 along the first direction F1. Specifically, the two first guide rails 115 are arranged at intervals along the second direction F2 on the two first frames 1111, and the first guide rails 115 are located between the electric cylinder connecting plate 112 and the fixing plate 113. The first heating device 120 is slidably connected to the two first guide rails 115, enabling the first heating device 120 to move along the first direction F1, and the first heating device 120 reciprocates between the electric cylinder connecting plate 112 and the fixing plate 113. In this embodiment, the two first guide rails 115 are provided above the base 111, which means the position height of the two first guide rails 115 is higher than the upper top surface of the 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 setting guide rails at the bottom in traditional bookbinding machines, it can avoid the glue in the flange being thrown out and dripping on the guide rails set 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 120 being unable to move smoothly along the first direction F1.

[0035] The base 111 further includes two third frames 1113. The two third frames 1113 are both arranged parallel to the first frame 1111. The two third frames 1113 are arranged at intervals along the second direction F2 between the two first frames 1111, and the two ends of the two third frames 1113 are respectively abutted and fixed to the two second frames 1112. At the same time, the upper surface of the third frame 1113 is lower than the upper surface of the first frame 1111, that is, the height of the third frame 1113 is less than the height of the first frame 1111. The upper surfaces of the two third frames 1113 are both provided with second guide rails 116 extending along the first direction F1, and the second guide rails 116 are located between the electric cylinder connecting plate 112 and the fixing plate 113. And in the second direction F2, the two third frames 1113 are located between the two first frames 1111, so the two second guide rails 116 are also between the two first guide rails 115. The first support device 140 is slidably connected to the two second guide rails 116, enabling the first support device 140 to move along the first direction F, and the first support device 140 reciprocates between the first heating device 120 and the fixing plate 113. Among them, the position height of the two second guide rails 116 is higher than the upper surface of the third frame 1113, and the specific setting is similar to that of the first guide rail 115, so it will not be elaborated here.

[0036] Refer to Figures 1 - 3, the first heating device 120 includes a first pressing plate 121, an intermediate transition plate 122, a plurality of second guide rods 123, and a positioning and adjusting device 124. In this embodiment, the first pressing plate 121 is an irregular rectangular plate member with grooves on both sides, and is used to clamp and fix the first flange 22. The intermediate transition plate 122 is a regular rectangular plate member. Both the first pressing plate 121 and the intermediate transition plate 122 are movably arranged on the first guide rail 115 through sliders and are thus movably connected to the main body frame 110. Moreover, the first pressing plate 121 and the intermediate transition plate 122 are arranged at intervals along the first direction F1. Among them, the intermediate transition plate 122 is arranged close to the electric cylinder connecting plate 112. At the same time, the first pressing plate 121 and the intermediate transition plate 122 are fixedly connected by four second guide rods 123, so that the first pressing plate 121 and the intermediate transition plate 122 can move integrally along the first direction F1 on the base 111. Among them, the four second guide rods 123 are arranged in a rectangular distribution, that is, the ends of the four second guide rods 123 form the four vertices of a rectangle, making the positions between the first pressing plate 121 and the intermediate transition plate 122 relatively fixed and the connection more stable. In other embodiments, the four second guide rods can also be arranged in other patterns, which is not limited here, and the number of the second guide rods is not specifically limited, as long as the first pressing plate and the intermediate transition plate can be fixedly connected. Further, first through holes 125 are provided at the four top corners of the first pressing plate 121, and second through holes 126 are provided at the four top corners of the intermediate transition plate 122. After the first through holes 125 and the second through holes 126 are matched and corresponding, the first guide rods 114 are respectively passed through them, so that the first heating device 120 is fixed on the base 111, and at the same time, it is ensured that the axis of the first flange 22 clamped on the first heating device 120 is parallel to the first direction F1.

[0037] Combined with Figure 4, the positioning and adjusting device 124 is fixedly connected between the first pressing plate 121 and the intermediate transition plate 122, that is, the positioning and adjusting device 124 is fixedly connected to the side of the first pressing plate 121 away from the first supporting device 140. The positioning and adjusting device 124 includes a connecting seat 1241, a base 1242 and a positioning block 1243. The connecting seat 1241 is fixedly connected between the first pressing plate 121 and the intermediate transition plate 122, and the connecting seat 1241 is arranged along the first direction F1. The base 1242 is slidably connected to the connecting seat 1241. Specifically, a third guide rail 1244 is provided above the connecting seat 1241, and the third guide rail 1244 is also arranged along the first direction F1. The base 1242 is movably arranged on the third guide rail 1244 through a slider, so that the base 1242 can move along the first direction F1 on the third guide rail 1244. The base 1242 includes a first connecting plate and a second connecting plate connected to each other. The first connecting plate and the second connecting plate form an L-shaped structure. The first connecting plate is movably connected to the third guide rail 1244, and the positioning block 1243 is fixedly connected to the second connecting plate. A first through hole 12431 is provided on the positioning block 1243 for detachably fixing the positioning block 1243 to the second connecting plate. A second through hole 12432 is also provided on the positioning block 1243 for positioning and connecting with the end of the conductive rod 24.

[0038] Specifically, the end of the conductive rod 24 extending out of the first flange 22 is provided with a positioning hole for the positioning and installation of the composite insulator 20. In the traditional bonding method of the composite insulator, since there is no positioning device for the positioning hole at the end of the conductive rod, it is usually necessary to perform secondary processing on the conductive rod to form the positioning hole after the conductive rod is bonded, that is, after the position of the conductive rod and the first flange is relatively fixed, according to the use requirements. In this application, the positioning hole can be formed by one-time processing during the initial processing of the conductive rod 24. When the composite insulator 20 is bonded on the bonding machine 100, by setting the positioning and adjusting device 124, a pin (not shown in the figure) is inserted into the second through hole 12432 of the positioning block 1243. After the conductive rod 24 is driven to pass through the inner cavity of the insulator 21 and extend out of the first flange 22, the positioning hole at the end of the conductive rod 24 is matched and fixed with the pin, so that the position of the conductive rod 24 is fixed, and then there is no need to process the positioning hole after the conductive rod 24 is bonded and fixed. Therefore, by setting the positioning and adjusting device 124 on the bonding machine 100, the positioning hole can be formed when the conductive rod 24 is processed. When bonding, only need to accurately position the conductive rod 24 through the positioning and adjusting device 124 and then perform bonding, which can save the process of reprocessing the conductive rod 24, improve the production efficiency of the composite insulator 20, and reduce the production cost of the composite insulator 20 at the same time. At the same time, the positioning block 1243 is detachably fixed to the base 1242, and the corresponding positioning block 1243 can be replaced according to different specifications of the composite insulator 20 for matching, with higher versatility.

[0039] Continue to refer toFigure 1 and Figure 2 The pressure device 160 that drives the first heating device 120 is the first pressure device 161. The first pressure device 161 is fixedly connected between the electric cylinder connecting plate 112 and the intermediate transition plate 122, and is specifically arranged on the side of the intermediate transition plate 122 away from the first pressing plate 121. The first pressure device 161 applies pressure to the entire first heating device 120 by directly applying pressure to the intermediate transition plate 122, and then applies a cementing pressure to the first flange 22 clamped on the first heating device 120, so that the first flange 22 is in close contact with the insulator 21, thereby ensuring that the mating position when the first flange 22 is sleeved on the outer periphery of the insulator 21 meets the design requirements of the composite insulator 20 and guaranteeing the cementing quality.

[0040] Combined with Figure 5

[0040] , the first pressure device 161 includes a driving rod 1611, a pressing head 1612 and a pressure sensor 1613. The driving rod 1611 drives the pressing head 1612 to move the first heating device 120 along the first direction F1 and provides a cementing pressure during the cementing process. The pressure of the first pressure device 161 is adjustable within the range of 0.5 - 5T to meet the cementing requirements of different types of composite insulators.

[0041] Among them, the driving rod 1611 is a long rod-shaped structure. The cross-section of the end of the driving rod 1611 close to the pressing head 1612 is circular, which is convenient for connecting with the pressing head 1612. 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 1611 and the electric cylinder connecting plate 112 without slipping. The pressing head 1612 is a cylindrical structure. The end of the driving rod 1611 in contact with the pressing head 1612 is provided with a connecting block 16111 for the fixed connection between the driving rod 1611 and the pressing head 1612. The connecting block 16111 is a cylindrical structure, and the diameter of the cross-section of the connecting block 16111 is larger than the diameter of the cross-section of the end of the driving rod 1611 close to the pressing head 1612. In other embodiments, the shapes of the driving rod and the connecting block can also be other shapes, such as the driving rod is a prismatic structure and the connecting block is a cuboid structure, which is not specifically limited here and shall be subject to actual requirements.

[0042] The pressure sensor 1613 is disposed between the pressure head 1612 and the first heating device 120. Specifically, the first pressure device 161 further includes a pressure plate 1614 which is a rectangular plate member. The first pressure device 161 is connected to the first heating device 120 through the pressure plate 1614. The cross-section of the pressure plate 1614 is larger than that of the pressure head 1612. Conducting pressure through the pressure plate 1614 can ensure the balance, stability and persistence of pressure during the gluing process. The pressure sensor 1613 is disposed between the pressure head 1612 and the pressure plate 1614, and can accurately sense the pressure between the first pressure device 161 and the first heating device 120. In this embodiment, the precision of the pressure sensor 1613 is 100N, and it can cooperate with the driving rod 1611 to sense and adjust the gluing pressure applied by the first pressure device 161. That is, when the pressure detected by the pressure sensor 1613 fails to reach the required gluing pressure, a signal is transmitted to the electrical cabinet 102, and then the driving rod 1611 is controlled to drive the pressure head 1612 to continuously apply pressure to the first heating device 120, so that the first heating device 120 moves along the first direction F1 towards the fixed plate 113 until the pressure detected by the pressure sensor 1613 reaches the required gluing pressure; when the pressure exceeds the required gluing pressure, the driving rod 1611 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 generated between the first flange 22 and the insulator 21 due to 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 precision of the pressure sensor can also be of other types, as long as it can meet the gluing requirements of the composite insulator.

[0043] The first pressure device 161 further includes a locking block 1615. The locking block 1615 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 16111. 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 1611 close to the pressing head 1612. When the locking block 1615 is fixed to the pressing head 1612, a stepped receiving cavity is formed between the locking block 1615 and the pressing head 1612, and the driving rod 1611 and the connecting block 16111 are exactly clamped in the stepped receiving cavity. During assembly, first fixedly connect the locking block 1615 and the pressing head 1612, then clamp the connecting block 16111 in the stepped receiving cavity, which can facilitate positioning, and then fixedly connect the connecting block 16111 and the pressing head 1612 to achieve the fixed connection between the driving rod 1611 and the pressing head 1612. Further, since a stepped receiving cavity is formed between the locking block 1615 and the pressing head 1612, the connecting block 16111 can also be directly clamped in the stepped receiving cavity, and the fixed connection between the driving rod 1611 and the pressing head 1612 can be achieved without further fixation.

[0044] Among them, the driving rod 1611 is driven by a servo motor. Through the servo motor, the telescopic distance of the driving rod 1611 can be accurately controlled. Cooperating with the pressing head 1612, the pressure plate 1614, and the pressure sensor 1613, the first heating device 120 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 the first heating device and the second heating device can clamp the composite insulator and maintain a stable gluing pressure.

[0045] In this embodiment, the locking block 1615 and the pressing head 1612, the pressing head 1612 and the pressure plate 1614, and the pressure plate 1614 and the first heating device 120 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.

[0046] 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 functions of the pressure device, and no specific limitation is made here.

[0047] Continue to combine Figure 6, the first heating device 120 clamps and fixes the first flange 22 through the first pressing plate 121, and heats the first flange 22 to fixedly bond the first flange 22 to one end of the insulator 21. The first pressing plate 121 includes a first body 1211, and four protruding edge blocks 1212 are provided at the four corners of the first body 1211. First through holes 125 are provided on the four edge blocks 1212 for respectively passing through four first guide rods 114, so that the first pressing plate 121 can move along the first guide rods 114, and the first heating device 120 is movably arranged on the main body frame 110. A first heat insulation plate 1213 and a first heating plate 1214 are fixed on the first body 1211. The first heating plate 1214, the first heat insulation plate 1213 and the first body 1211 are fixedly connected in sequence and are arranged on one side of the first body 1211 facing the first supporting device 140, so that the first heating plate 1214 is in direct contact with the first flange 22 of the composite insulator 20 for heating, and the first body 1211 is movably connected to the main body frame 110. The arrangements of the first body 1211 and the first heat insulation plate 1213 are both to prevent the first heating plate 1214 from contacting other components and reduce heat loss. At the same time, by movably connecting the first body 1211 to the main body frame 110 instead of directly movably connecting the first heating plate 1214 to the main body frame 110, it is also to prevent the first heating plate 1214 from contacting other components and reduce heat loss.

[0048] Among them, the first heating plate 1214 is a rectangular plate member for heating the first flange 22 during the bonding process. Heating tubes are arranged in the first heating plate 1214. In this embodiment, the heating tubes in the first heating plate 1214 are resistive heating tubes, which have high heating efficiency, automatic temperature control, and are convenient for installation and maintenance. In other embodiments, other types of heating tubes can be set as long as the temperature required for bonding the first flange can be achieved, and no limitation is made here. The first heat insulation plate 1213 is a rectangular plate member with the same length and width as the first heating plate 1214. The setting of the first heat insulation plate 1213 prevents heat transfer between the first heating plate 1214 and the first body 1211, reduces heat loss, and improves heating efficiency.

[0049] There are also two bumps 1215 provided on the first pressing plate 121. The two bumps 1215 are arranged on the first body 1211 and are respectively located above and below the first heat insulation plate 1213 and the first heating plate 1214. The bump 1215 is of a cuboid structure, with its length being the same as that of the first heat insulation plate 1213 and the first heating plate 1214, and its thickness being the sum of the thicknesses of the first heat insulation plate 1213 and the first heating plate 1214. And the two bumps 1215 clamp the first heat insulation plate 1213 and the first heating plate 1214. On the one hand, it plays a role in further fixing the first heat insulation plate 1213 and the first heating plate 1214, making their connection with the first body 1211 reliable. On the other hand, the two bumps 1215 abut against both sides of the first heating plate 1214, playing a role in further heat insulation, reducing the heat loss of the first heating plate 1214 and improving the heating efficiency. The bump 1215 can also be made of heat-insulating material to better achieve the heat-insulating effect.

[0050] In this embodiment, the first heating plate 1214, the first heat insulation plate 1213 and the first body 1211 are fixedly connected by bolts, and the first body 1211 and the bump 1215 are also fixedly connected by bolts. In other embodiments, the first heating plate, the first heat insulation plate, the first body, and the bump can also be of other shapes. The first heating plate, the first heat insulation plate, and the first body can also be connected by means of clamping or the like, and the bump can also be not provided, as long as the reliable connection of the first heating plate, the first heat insulation plate, and the first body can be achieved, and their respective functions can be realized.

[0051] The first pressing plate 121 is further provided with a first positioning mechanism 1216 for fixing the first flange 22. The first positioning mechanism 1216 includes two positioning members 12161, a positioning rod 12162, and a positioning handwheel 12163. The positioning rod 12162 and the positioning handwheel 12163 are used to drive the two positioning members 12161 to move synchronously towards or away from each other. Through the two-way synchronous adjustment of the two positioning members 12161, the first flange 22 can be quickly fixed on the first pressing plate 121, and the operation is simple.

[0052] Among them, the first positioning mechanism 1216 is arranged on the horizontal center line of the first pressing plate 121. The positioning rod 12162 horizontally penetrates between the first heat insulation plate 1213 and the first heating plate 1214 and is located at the horizontal center line of the first heating plate 1214. Two through grooves for accommodating the positioning members 12161 are also provided at the horizontal center line of the first heating plate 1214. The two positioning members 12161 move synchronously towards or away from each other in the two through grooves respectively. The two positioning members 12161 are movably connected to the positioning rod 12162. The positioning handwheel 12163 is used to adjust the relative distance between the two positioning members 12161, that is, by rotating the positioning handwheel 12163, the two positioning members 12161 move synchronously towards or away from each other along the positioning rod 12162. When the diameter of the first flange 22 to be glued is small, the two positioning members 12161 are adjusted to move synchronously towards each other along the positioning rod 12162; when the diameter of the first flange 22 to be glued is large, the two positioning members 12161 are adjusted to move synchronously away from each other along the positioning rod 12162. By synchronously adjusting the relative distance between the two positioning members 12161, the rapid installation of the first flanges 22 of different specifications can be realized. The boundaries of the through grooves on the first heating plate 1214 can define the minimum distance and the maximum distance between the two positioning members 12161, avoiding the collision of the two positioning members 12161 and damaging the equipment, and unable to heat evenly. Specifically, in this embodiment, the positioning rod 12162 is a lead screw, a reverse thread is provided on the lead screw, and a matching threaded hole is provided on the positioning member 12161. The lead screw penetrates through the threaded hole. Of course, the first positioning mechanism can also adopt other structures as long as it can adjust the position to position the flange.

[0053] Each positioning member 12161 is provided with a set of mounting holes. Each set of mounting holes includes a threaded hole and a through hole, which are used to fix the first flange 22 of different structural forms. Specifically, a number of symmetric flange mounting holes (not shown in the figure) are provided on the first flange 22. Usually, the flange mounting holes in the market are either threaded holes or through holes. When the flange mounting holes on the first flange 22 are threaded holes, rotate the positioning handwheel 12163 to make the two through holes on the two positioning members 12161 correspond to the two flange mounting holes on the first flange 22 and pass through the fixing member, and then rotate the positioning handwheel 12163 to clamp the fixing member in the corresponding through hole and flange mounting hole, thereby locking the first flange 22 and realizing the installation and fixation of the first flange 22; when the flange mounting holes on the first flange 22 are through holes, rotate the positioning handwheel 12163 to make the two threaded holes on the two positioning members 12161 correspond to the two flange mounting holes on the first flange 22 and pass through the fixing member, and then rotate the positioning handwheel 12163 to clamp and lock the first flange 22, realizing the installation and fixation of the first flange 22, that is, the fixing member passes through the threaded hole and the through hole at the same time, which can ensure that after adjusting the distance between the two positioning members 12161 through the positioning handwheel 12163, the first flange 22 can be locked with the positioning member 12161, avoiding slippage between the first flange 22 and the first heating plate 1214 during the gluing process and resulting in unqualified products.

[0054] In this embodiment, the fixing member is a bolt. In other embodiments, the fixing member can also be a pin or other structures, and the first positioning mechanism can also be other structures, as long as the reliable connection between the first flange and the first pressing plate can be realized, and no specific limitation is made here.

[0055] Continue to refer to Figure 6 , a temperature sensor 1217 is further provided on the first pressing plate 121, and the temperature sensor 1217 is arranged on the first body 1211. The temperature sensor 1217 can monitor the surface temperature of the first flange 22. When the temperature does not reach the required temperature for gluing, the first heating plate 1214 is controlled by the electrical cabinet 102 to continuously increase the temperature. When the temperature exceeds the set temperature, the first heating plate 1214 is controlled to stop heating immediately, without manual monitoring, saving labor costs.

[0056] In this embodiment, the temperature sensor 1217 is an infrared temperature sensor, which uses non-contact temperature measurement, does not affect the gluing state of the first flange 22, 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 the gluing temperature of the first flange can be monitored in real time and accurately, and it can also be arranged at other positions as long as the temperature can be monitored, and no specific limitation is made here.

[0057] The first pressing plate 121 is further provided with an adhesive receiving groove 1218. The adhesive receiving groove 1218 is fixed on the first body 1211, located below the first heating plate 1214 and extends along the first direction F1 to the outside of the first heating plate 1214. The adhesive receiving groove 1218 can be used to receive the glue overflowing from the first flange 22, ensuring that the adhesive receiving groove 1218 can move synchronously with the first body 1211 along the first direction F1 and always be located below the first heating plate 1214. That is, when the first flange 22 is fixed on the first heating plate 1214 for gluing with the insulator 21, the adhesive receiving groove 1218 is always located below the first flange 22 to timely receive the glue overflowing from the first flange 22, avoiding the difficulty of cleaning the glue dropped on the ground.

[0058] Continuing in combination with Figure 1 and Figure 7 , the second heating device 130 includes a second pressing plate 131, a second heat insulation plate 132 and a second heating plate 133 which are fixedly connected in sequence. The second heating plate 133 faces the second supporting device 150. The second heating device 130 clamps and fixes the second flange 23 through the second pressing plate 131 and heats the second flange 23 to fix the second flange 23 to the other end of the insulator 21 by gluing. The second pressing plate 131 includes a second body 1311 and two auxiliary plates 1312. The second body 1311 is a rectangular plate member. The two auxiliary plates 1312 are arranged at intervals along the second direction F2 and are respectively fixedly connected to the two side edges of the second body 1311. The two auxiliary plates 1312 are located on the side of the second body 1311 facing the first heating device 120, and the plate surfaces of the two auxiliary plates 1312 are parallel to each other. The second heat insulation plate 132 and the second heating plate 133 are fixed on the second body 1311. The second heating plate 133, the second heat insulation plate 132 and the second body 1311 are fixedly connected in sequence. The second heating plate 133 faces the first heating device 120 to directly contact and heat the second flange 23 of the composite insulator 20. The second body 1311 is movably connected to the main body frame 110.

[0059] Specifically, two fourth guide rails 117 are provided on the base 111. The fourth guide rails 117 extend and are fixed above the base 111 along the first direction F1. The two fourth guide rails 117 are spaced apart along the second direction F2, and in the second direction F2, the two fourth guide rails 117 are located between the two first guide rails 115; in the first direction F1, the fourth guide rail 117 is located between the first support device 140 and the second frame 1112 of the base 111 that is far from the cylinder connecting plate 112. The second heating device 130 is slidably connected to the two fourth guide rails 117 through the second pressing plate 131, that is, the second pressing plate 131 is movably arranged on the fourth guide rail 117 through a slider, so that the second heating device 130 can move along the first direction F1, and the second heating device 130 moves back and forth between the first support device 140 and the second frame 1112 of the base 111 that is far from the cylinder connecting plate 112. At the same time, in the vertical direction, the fourth guide rail 117 is arranged higher than the first guide rail 115. By providing a cushion seat 118 with a metal frame structure on the base 111, the fourth guide rail 117 is erected on the cushion seat 118. By arranging the two fourth guide rails 117 between the two first guide rails 115 and the fourth guide rail 117 being arranged higher than the first guide rail 115, the second guide rail 116 and the fourth guide rail 117, which are also arranged between the two first guide rails 115, are prevented from intersecting and interfering with each other. Among them, the structure and setting method of the fourth guide rail 117 are similar to those of the first guide rail 115, and will not be elaborated here.

[0060] The settings of the second body 1311 and the second heat insulation plate 132 are both to prevent the second heating plate 133 from contacting other components and reduce heat loss. At the same time, by movably connecting the second body 1311 to the main body frame 110 instead of directly movably connecting the second heating plate 133 to the main body frame 110, it is also to prevent the second heating plate 133 from contacting other components and reduce heat loss. Among them, the structure and setting method of the second heat insulation plate 132 are similar to those of the first heat insulation plate 1213, and the structure and setting method of the second heating plate 124 are similar to those of the first heating plate 1214, and will not be elaborated here.

[0061] The second pressing plate 131 further includes a bottom plate 1313. The bottom plate 1313 is located at the bottom of the second body 1311 and the two auxiliary plates 1312, and simultaneously connects the second body 1311 and the two auxiliary plates 1312. A second positioning mechanism 1314 is provided on the bottom plate 1313 for fixing the second flange 23. The second positioning mechanism 1314 includes a bottom support 13141 and two side supports 13142. The bottom support 13141 is provided on the bottom plate 1313. The two side supports 13142 are respectively arranged at both ends of the bottom support 13141 along the second direction F2. And both sides of the bottom support 13141 are fixedly connected to the two auxiliary plates 1312. The two auxiliary plates 1312 fixedly connect the bottom support 13141 to the second pressing plate 131, and then the entire second positioning mechanism 1314 is stabilized on the second pressing plate 131, and can clamp the second flange 23 more stably. Wherein, the inner sides of the two side supports 13142 are both inclined surfaces, and the two side supports 13142 form a V-shaped support surface, which is suitable for clamping flanges with various contour shapes of the composite insulator 20. Elastic pads are also provided on the inner sides of the two side supports 13142 to prevent the second flange from being knocked or damaged after being over-clamped. Wherein, the side support 13142 is detachably fixed to the bottom support 13141. When the outer peripheral surface of the second flange is a special-shaped structure, the side support can be designed into a structure suitable for the second flange, which expands the versatility of the second positioning mechanism 1314.

[0062] Continue to refer to Figure 7 , the pressure device 160 for driving the second heating device 130 is the second pressure device 162. The second pressure device 162 is fixedly connected to the side of the second pressing plate 131 away from the second support device 150. The second pressure device 162 is arranged to apply pressure to the second heating device 130, and then apply a cementing pressure to the second flange 23 clamped on the second heating device 130, so that the second flange 23 is in close contact with the insulator 21, thereby ensuring that the mating position when the second flange 23 is sleeved on the insulator 21 meets the design requirements of the composite insulator 20 and guaranteeing the cementing quality. The structure of the second pressure device 162 is similar to that of the first pressure device 161, and will not be elaborated here.

[0063] Refer to Figure 1 and Figure 8, two first support devices 140 are arranged at intervals in the first direction F1 between the first pressing plate 121 and the fixed plate 113, and are used to support the insulator 21, so that both ends of the insulator 21 are sleeved and fixed with the first flange 22 and the second flange 23 respectively. The first support device 140 includes a bracket 141, a first moving bracket 142, a second moving bracket 143 and a first support portion 144. Among them, the bracket 141 is slidably connected to the main body frame 110. Specifically, the bracket 141 is slidably connected to the two second guide rails 116 through sliders, so that the first support device 140 is movably arranged on the main body frame 110 in the first direction F1, and the first support device 140 moves back and forth between the first pressing plate 121 and the fixed plate 113.

[0064] The first moving bracket 142 is movably arranged on the bracket 141 in the second direction F2, and the second moving bracket 143 is movably arranged on the first moving bracket 142 in the vertical direction. Among them, a vertically arranged guide frame 147 is fixedly connected to the first moving bracket 142, and the second moving bracket 143 is slidably connected to the guide frame 147, so that the second moving bracket 143 can move back and forth in the vertical direction. Specifically, the first support device 140 further includes a first handwheel 145 and a second handwheel 146. By rotating the first handwheel 145, the first moving bracket 142 can be controlled to move in the second direction F2, and by rotating the second handwheel 146, the second moving bracket 143 can be controlled to move up and down in the vertical direction. By controlling the insulator 21 to move in the second direction F2 and the vertical direction through the first moving bracket 142 and the second moving bracket 143, on the one hand, it is convenient to adjust the concentricity between the insulator 21 placed on the first support device 140 and the first flange 22 fixed on the first heating device 120, ensuring the smooth subsequent cementing; on the other hand, it is convenient for the hoisting of the composite insulator 20. By adjusting the distance between the composite insulator 20 and the components of the cementing machine 100, the composite insulator 20 is prevented from being damaged by collision during the hoisting and transportation process. Since the first support device 140 mainly plays a role in supporting the insulator 21, its movement in the first direction F1 can be roughly adjusted manually, that is, manually push the first support device 140 to slide along the two second guide rails 116, as long as it can stably support the composite insulator 20. In other embodiments, a servo motor can also be provided to control the movement of the first moving bracket in the second direction, the second moving bracket in the vertical direction, and the first support device in the first direction to achieve automated operation and precisely control the moving distance.

[0065] The first support part 144 is located on the second moving bracket 143. The first support part 144 is a V-shaped plate. Since the insulator 21 is usually in a cylindrical structure, the V-shaped opening of the first support part 144 enables the insulator 21 to be stuck when placed on the first support part 144, and it is not easy to roll and slip. Since the first support part 144 is in direct contact with the insulator 21, in order to avoid damaging the silicone rubber umbrella skirt on the surface of the insulator 21, the contact part of the first support part 144 with the composite insulator 20 is made of nylon. The nylon material has high mechanical strength, good toughness, a smooth surface, and a small friction coefficient, and will not damage the surface of the composite insulator 20. In other embodiments, the contact part of the first support part with the composite insulator 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 insulator.

[0066] In this embodiment, the number of the first support devices 140 is two. The two first support devices 140 can support the composite insulator 20 more stably, avoiding the phenomenon of unstable force when there is only one first support device 140 and it is not in the exact middle of the composite insulator 20, which may cause the inclination and dropping of the composite insulator 20. In other embodiments, the number of the first support devices is not limited, as long as it can support the composite insulator to keep it balanced.

[0067] Refer to Figure 1 、 Figure 9 and Figure 10 and

[0068] Two second support devices 150 are arranged at intervals along the first direction F1 between the first support device 140 and the second heating device 130 for supporting the conductive rod 24 to fix the second flange 23 and the insulator 21 in a sleeved manner. The second support device 150 includes a mounting part 151, a second support part 152, and a lifting part 153. The mounting part 151 is used to fixedly connect the second support device 150 to the main body frame 110, that is, to fixedly connect the second support device 150 to the base 111. The second support part 152 is used to directly support the conductive rod 24. The lifting part 153 is arranged at the bottom of the second support part 152, and the lifting part 153 can move back and forth in the vertical direction, and is used to support the second support part 152 to move back and forth in the vertical direction, so that the second support device 150 can arbitrarily support the conductive rod 24 in the vertical direction.The lifting part 153 includes a top connecting plate 1531, a piston rod 1532, a third guide rod 1533, a cylinder mounting seat 1534 and a first cylinder 1535. The top connecting plate 1531 is of a flat plate structure. One end of the piston rod 1532 is fixedly connected to one side plate surface of the top connecting plate 1531, and the other end is inserted into the first cylinder 1535. Under the driving force of the first cylinder 1535, the piston rod 1532 can move back and forth in the first cylinder 1535 in the vertical direction. Another side plate surface of the top connecting plate 1531 is fixedly connected with a second supporting part 152. The piston rod 1532 moves back and forth in the vertical direction, which can drive the second supporting part 152 to move back and forth in the vertical direction, and then enable the second supporting device 150 to support the conductive rod 24 arbitrarily in the vertical direction.

[0069] The cylinder mounting seat 1534 includes a first connecting part 15341 and a second connecting part 15342. The first connecting part 15341 is provided with a first mounting hole 15343. The first connecting part 15341 abuts against the top of the first cylinder 1535, and the cylinder mounting seat 1534 is fixedly connected to the first cylinder 1535 through the first mounting hole 15343. The first connecting part 15341 is also provided with a piston rod through hole 15344. The piston rod 1532 is inserted into the first cylinder 1535 through the piston rod through hole 15344, and then moves back and forth in the first cylinder 1535 in the vertical direction. The second connecting part 15342 is provided in two. The two second connecting parts 15342 are respectively fixedly connected to two opposite side surfaces of the first connecting part 15341. The first cylinder 1535 is clamped between the two second connecting parts 15342. Among them, the third guide rod 1533 is provided in two. The two third guide rods 1533 are respectively arranged on both sides of the piston rod 1532. The second connecting part 15342 is provided with a guide rod through hole 15345. One end of the third guide rod 1533 is fixedly connected to one side plate surface of the top connecting plate 1531, and the other end is inserted into the second connecting part 15342 through the guide rod through hole 15345. The arrangement of the third guide rod 1533 can play a guiding role, reduce the radial force borne by the piston rod 1532, and avoid the piston rod 1532 from shifting radially.

[0070] On the side of the second connecting portion 15342 away from the first cylinder 1535, a plurality of second mounting holes 15346 are further provided. The mounting portion 151 is fixedly connected to the cylinder mounting seat 1534 through the second mounting holes 15346. Specifically, the mounting portion 151 includes a first mounting plate 1511 and a second mounting plate 1512. After the first mounting plate 1511 and the second mounting plate 1512 are connected to each other, an L-shaped structure is formed. The side of the first mounting plate 1511 away from the second mounting plate 1512 abuts against the second connecting portion 15342 and is fixedly connected to the second connecting portion 15342 through the second mounting holes 15346. The second mounting plate 1512 is fixedly mounted on the base 111. A reinforcing member 1513 is further provided between the first mounting plate 1511 and the second mounting plate 1512. The reinforcing member 1513 connects the adjacent sides of the first mounting plate 1511 and the second mounting plate 1512 at the same time, making the structure of the second connecting portion 15342 more stable, and then making the second supporting device 150 stably arranged on the base 111.

[0071] Continue to refer to Figure 9 , the second supporting portion 152 includes a supporting seat 1521 and a V-shaped roller support 1522. The supporting seat 1521 is fixedly connected to the top connecting plate 1531 of the lifting portion 153. The second supporting portion 152 can be driven by the lifting portion 153 to move back and forth in the vertical direction, and then the second supporting device 150 can support the conductive rod 24 arbitrarily in the vertical direction. The V-shaped roller support 1522 includes a plurality of evenly distributed rollers. The plurality of rollers are fixedly connected to the supporting seat 1521 and are arranged in a V-shaped opening as a whole, so that the conductive rod 24 can be clamped when placed on the second supporting portion 152 and is not likely to roll and slip. Since the second supporting portion 152 is in direct contact with the conductive rod 24, in order to avoid damaging the outer surface of the conductive rod 24, the V-shaped roller support 1522 is made of nylon material. The nylon material has high mechanical strength, good toughness, smooth surface and small friction coefficient, and will not cause damage to the surface of the composite insulator 20. In other embodiments, the contact portion of the second supporting portion with the composite insulator can be made of other materials, as long as it can ensure that its surface is smooth and will not cause damage to the outer surface of the conductive rod.

[0072] Refer to Figure 1 and Figure 11, the fixing plate 113 is a rectangular plate member. The fixing plate 113 is fixedly connected to the base 111 in the vertical direction. On the side of the fixing plate 113 close to the first heating device 120, there are two fifth guide rails 1131 extending in the vertical direction, and the two fifth guide rails 1131 are spaced apart along the second direction F2. The reinforcing plate 1132 is slidably connected to the two fifth guide rails 1131 through sliders. One side of the reinforcing plate 1132 is also connected with a second cylinder 1133. Driven by the second cylinder 1133, the reinforcing plate 1132 can move vertically on the fifth guide rails 1131. The fixing plate 113 is also provided with a passing portion 1134. The passing portion 1134 is located between the two fifth guide rails 1131 and is a through channel, and its size is larger than the size of the second flange 23, providing a passing channel for the second flange 23 and the conductive rod 24. When the second flange 23 is driven to pass through the passing portion 1134 and is located at the end position of the insulator 21, the reinforcing plate 1132 is driven to move vertically towards the second flange 23 and is clamped on the second flange 23 to further fix the second flange 23. Among them, the second cylinder 1133 is fixed on the side of the fixing plate 113 close to the first heating device 120 and is located on one side of one fifth guide rail 1131 away from the other fifth guide rail 1131. Four third mounting holes 1135 are provided on the fixing plate 113, and four first guide rods 114 are fixedly connected to the fixing plate 113 through the third mounting holes 1135.

[0073] Continue to refer to Figure 2 , the bookbinding machine 100 further includes a bellows cover 170. The bellows cover 170 is movably arranged on the two first guide rods 114 along the length direction of the main body frame 110 and is located below the glue receiving groove 1218. Specifically, the bellows cover 170 includes a telescopic portion. The telescopic portion is in the shape of a bellows and is formed by connecting a plurality of pleated portions. The telescopic portion can be stretched and contracted in the length direction of the main body frame 110. Arranging the bellows cover 170 below the glue receiving groove 1218 can receive the glue overflowing from the glue receiving groove 1218 and prevent the glue in the glue receiving groove 1218 from dripping on the ground and being difficult to clean when there is too much glue. In this embodiment, the number of the bellows covers 170 is one. In other embodiments, bellows covers can also be arranged below both glue receiving grooves, which is not specifically limited here.

[0074] The working process of the gluing machine 100 is as follows: Fix the first flange 22 to the first heating device 120, fix the second flange 23 connected with the conductive rod 24 to the second heating device 130, horizontally place the insulator 21 on two first supporting devices 140, control the movement of the insulator 21 through the first moving bracket 142 and the second moving bracket 143 so that the first flange 22, the second flange 23 and the insulator 21 are coaxial, drive the first heating device 120 to move along the length direction of the main body frame 110 through the first pressure device 161, drive the second heating device 130 to move along the length direction of the main body frame 110 through the second pressure device 162, and at the same time adjust the positioning of the conductive rod 24 through the positioning adjustment device 124 until the first flange 22 and the second flange 23 are respectively sleeved on both ends of the insulator 21 and clamp the insulator 21, so as to realize the fitting installation of the first flange 22 and the second flange 23 with the insulator 21 and maintain the required gluing pressure. By injecting glue into the glue injection holes of the first flange 22 and the second flange 23 respectively, heat the first heating plate 1214 and the second heating plate 133 to the required gluing temperature, and cure the glue to realize the gluing of the composite insulator 20.

[0075] The beneficial effects of this application are as follows: Different from the prior art, the gluing machine of this application includes a main body frame, a first heating device, a second heating device, a first supporting device, a second supporting device and a pressure device, which can simultaneously glue the flanges at both ends of a hollow composite insulator with a conductive rod, realize the horizontal gluing process of the composite insulator with a conductive rod, and by setting the pressure device, keep the gluing pressure stable, avoid the phenomenon of bias voltage, and apply dynamic pressure 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 improve the product qualification rate, and is convenient to operate and has high production efficiency.

[0076] The above are only the embodiments of this application, and do not limit the patent scope of this application accordingly. 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 to other related technical fields, shall be equally included in the patent protection scope of this application.
