[0001] This application relates to the field of manufacturing technology of gas insulating bushings, and in particular to a drilling device. Background Technology

[0002] Gas-insulated bushings typically consist of an insulator, flanges fitted at both ends of the insulator, and a conductive rod. One end of the conductive rod is fixedly connected to one of the flanges, while the other end passes through the inner cavity of the insulator and extends out from the end of the other flange. The end face of the conductive rod extending out of the flange usually requires drilling for connection to other equipment. Furthermore, the holes on the conductive rod end face and the bolt holes on the flange have specific angular and positional requirements. Therefore, production typically involves assembly followed by drilling. However, existing drilling methods require the installation of positioning fixtures for each specification of gas-insulated bushing. These fixtures are numerous, the drilling process is cumbersome, manual labor is time-consuming, and demands high skill levels from operators, resulting in low production efficiency.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] See Figure 1 The gas-insulating bushing 20 includes an insulator, flanges respectively fitted at both ends of the insulator, and a conductive rod 21. One end of the conductive rod 21 is fixedly connected to one of the flanges, and the other end passes through the inner cavity of the insulator and extends out from the end of the other flange. This application provides a drilling device 100 for drilling holes in the end face of the conductive rod 21 extending out of the flange on the gas-insulating bushing 20. The drilling device 100 includes a base 110, a positioning and clamping mechanism 120, a support mechanism 130, and a drilling mechanism 140. The base 110 is a rectangular frame structure, and the two ends of the base 110 along its length direction are respectively the first end 111 and the second end 112 of the base 110. A positioning and clamping mechanism 120 is disposed at the first end 111 of the base 110. A support mechanism 130 is slidably disposed on the base 110 and away from the positioning and clamping mechanism 120. The support mechanism 130 can slide along the length direction of the base 110, that is, the support mechanism 130 can slide arbitrarily between the first end 111 and the second end 112 of the base 110. A gas insulating sleeve 20 is placed on the support mechanism 130. By operating the support mechanism 130, the gas insulating sleeve 20 can be moved along the length direction of the base 110, thereby moving the end of the conductive rod 21 extending out of the flange to the positioning and clamping mechanism 120 and fixing it to the positioning and clamping mechanism 120. A drilling mechanism 140 is disposed outside the base 110 and close to the first end 111 of the base 110, and is used to drill holes for positioning the conductive rod 21.

[0028] See Figures 1-3The positioning and clamping mechanism 120 includes a positioning plate 121, a central positioning element 122, a positioning pin 123, and a clamping device. The positioning plate 121 is vertically fixed on the base 110. The positioning plate 121 includes a first surface 1211 and a second surface 1212 arranged opposite to each other, and the first surface 1211 is close to the support mechanism 130. A first through hole 1213 is opened in the center of the positioning plate 121, which passes through the first surface 1211 and the second surface 1212. One end of the conductive rod 21 passes through the first through hole 1213 from the first surface 1211 of the positioning plate 121 to the second surface 1212, that is, one end of the conductive rod 21 passes out of the positioning plate 121. The clamping device includes a first clamping device 124 and a second clamping device 125. The center positioning member 122 is sleeved on one end of the conductive rod 21 and abuts against the second surface 1212 of the positioning plate 121. The center positioning member 122 is fixed on the positioning plate 121 by the first clamping device 124. At the same time, the flange of the gas insulating sleeve 20 abuts against the first surface 1211 of the positioning plate 121 and is fixed on the positioning plate 121 by the second clamping device 125.

[0029] Specifically, the positioning plate 121 has two first through slots 1214 along the vertical direction, and the two first through slots 1214 are located on the outside of the first through hole 1213. The positioning plate 121 has two second through slots 1215 along the horizontal direction, and the two second through slots 1215 are located on the outside of the first through hole 1213. That is, the two first through slots 1214 and the two second through slots 1215 are evenly distributed around the circumference of the first through hole 1213. The positioning plate 121 is also provided with a plurality of second through holes 1216 evenly arranged on both sides of the first through groove 1214. When one end of the conductive rod 21 passes through the positioning plate 121, the end face of the flange abuts against the first surface 1211 of the positioning plate 121. After the positioning pin 123 is inserted into the first through groove 1214 from the second surface 1212 of the positioning plate 121, the positioning pin 123 is fixed to the flange. At the same time, a central positioning member 122 is sleeved on one end of the conductive rod 21 to prevent the part of the conductive rod 21 from being too long and shaking during the drilling process. The first pressing device 124 presses the central positioning member 122 to fix the central positioning member 122 to the positioning plate 121. The second pressing device 125 is inserted into the second through groove 1215 from one side of the second surface 1212 of the positioning plate 121 and then into one side of the first surface 1211 of the positioning plate 121. The second pressing device 125 then presses the flange to fix the flange to the positioning plate 121. The clamping device is a rotary clamping cylinder.

[0030] Combination Figures 4-5As shown, the center positioning component 122 includes a positioning cylinder 1221 and a positioning disk 1222. The positioning cylinder 1221 has a hollow structure along the axial direction. The positioning disk 1222 extends radially outward from the outer periphery of the positioning cylinder 1221 to form an annular disk-shaped component. The positioning disk 1222 is located at the middle position of the positioning cylinder 1221 along its axial direction. When the positioning cylinder 1221 is sleeved and fixed to one end of the conductive rod 21, the positioning disk 1222 is fixedly connected to the second surface 1212 of the positioning plate 121. At this time, the closer to the method The positioning cylinder 1221 on the flange side is defined as the first positioning cylinder 12211, and the positioning cylinder 1221 on the side away from the flange is defined as the second positioning cylinder 12212. The inner cavities of the first positioning cylinder 12211 and the second positioning cylinder 12212 are connected and used to be sleeved on the outer circumferential surface of the conductive rod 21. The first positioning cylinder 12211 passes through the first through hole 1213 and is located in the inner cavity of the flange. Therefore, the outer diameter of the first positioning cylinder 12211 should be smaller than the inner diameter of the flange to facilitate the insertion of the first positioning cylinder 12211 into the inner cavity of the flange. The inner diameter of the positioning cylinder 1211 matches the outer diameter of the conductive rod 21, that is, the inner diameter of the positioning cylinder 1211 is equal to or slightly larger than the outer diameter of the conductive rod 21, facilitating the secure and stable sleeved attachment of the positioning cylinder 1211 to the outer circumference of the conductive rod 21. The outer diameters of the first positioning cylinder 12211 and the second positioning cylinder 12212 can be equal or unequal, as long as the first positioning cylinder 12211 can be inserted into the inner cavity of the flange.

[0031] The positioning plate 121 has a plurality of first positioning holes circumferentially arranged around the first through hole 1213, and the positioning disk 1222 has a plurality of second positioning holes corresponding to and matching the first positioning holes. After the first positioning holes and the second positioning holes are matched, fasteners are inserted to fix the center positioning member 122 to the positioning plate 121.

[0032] Meanwhile, the outer diameter of the first positioning cylinder 1211 is smaller than the diameter of the first through hole 1213, so as to be suitable for various specifications of center positioning parts 122, that is, suitable for various specifications of gas insulating sleeves 20, thus expanding the applicability of the positioning mechanism 120.

[0033] Combination Figure 6As shown, the positioning pin 123 includes a fixing part 1231 and a positioning part 1232. The fixing part 1231 is a rectangular plate, and the positioning part 1232 is a long rod similar to a pin. The positioning part 1232 is fixed to one side of the fixing part 1231. The fixing part 1231 has a third through hole 1233 that corresponds to and matches the second through hole 1216. After the positioning part 1232 of the positioning pin 123 passes through the first through groove 1214, the third through hole 1233 on the fixing part 1231 corresponds to and matches the second through hole 1216 on the positioning plate 121, and a fastener is inserted to fix the positioning pin 123 to the positioning plate 121. The end of the positioning part 1232 away from the fixing part 1231 passes through a bolt hole on the flange, and there are two positioning pins 123, which pass through two first through grooves 1214 and are fixed to the two bolt holes on the flange, thus fixing the gas insulating sleeve 20 in place.

[0034] Combination Figure 7 As shown, the support mechanism 130 is spaced apart along the length of the base 110 between the first end 111 and the second end 112 of the base 110, and is used to support the gas insulating sleeve 20. The support mechanism 130 includes a bracket 131, a first support 132, a second support 133, and a support part 134. Two guide rails 113 are provided on the base 110. The guide rails 113 are fixed above the base 110 along the length direction of the base 110. The two guide rails 113 are located between the first end 111 and the second end 112 of the base 110, and the two guide rails 113 are spaced apart in the width direction of the base 110. The bracket 131 is slidably connected to the two guide rails 113 through a slider, so that the support mechanism 130 moves back and forth between the first end 111 and the second end 112 of the base 110 along the length direction of the base 110, thereby fixing one end of the conductive rod 21 of the gas insulating sleeve 20 to the positioning plate 121.

[0035] The first support 132 is fixedly connected to the bracket 131 in a vertical direction. The first support 132 includes a plurality of first pillars 1321 and a first frame plate 1322. The two ends of the plurality of first pillars 1321 are respectively connected to and fixed to the bracket 131 and the first frame plate 1322, so that the first frame plate 1322 and the bracket 131 are spaced apart. The second support 133 is a movable support. The second support 133 is movably set on the first support 132 in a vertical direction. The second support 133 includes a plurality of second pillars 1331, a second frame plate 1332 and a third frame plate 1333. The two ends of the plurality of second pillars 1331 are respectively connected to and fixed to the second frame plate 1332 and the third frame plate 1333, so that the second frame plate 1332 and the third frame plate 1333 are spaced apart. At the same time, the third frame plate 1333 is movably connected to the first pillars 1321, so that the third frame plate 1333 can drive the second support 133 to move in a vertical direction. The first support plate 1322 is located between the second support plate 1332 and the third support plate 1333, allowing the second support 133 to move within the height range of the first support column 1321. There are four first support columns 1321 and four second support columns 1331, but other numbers are not limited here.

[0036] The support portion 134 is disposed on the second bracket 133. Specifically, the support portion 134 is disposed on the second frame plate 1332. The second bracket 133 drives the support portion 134 to move vertically, thereby supporting and positioning the gas insulating sleeve 20. The support portion 134 has a roller structure, which is used to engage between the skirts of the gas insulating sleeve 20, preventing it from rolling and slipping. Since the support portion 134 is in direct contact with the skirts of the gas insulating sleeve 20, to avoid damaging the skirts, the rollers of the support portion 134 are made of nylon. Nylon has high mechanical strength, good toughness, and a smooth surface with a low coefficient of friction, so it will not damage the surface of the gas insulating sleeve 20. In other embodiments, the contact area between the rollers on the support portion and the gas insulating sleeve can also be made of other materials, as long as the surface is smooth and will not damage the surface of the gas insulating sleeve.

[0037] The support mechanism 130 also includes a handwheel 135, which, when rotated, controls the reciprocating movement of the second bracket 133 in the vertical direction. Controlling the vertical movement of the gas insulating sleeve 20 via the second bracket 133 facilitates, on the one hand, adjusting the concentricity between the gas insulating sleeve 20 placed on the support mechanism 130 and the first through hole 1213 on the positioning plate 121, ensuring smooth positioning and connection; on the other hand, it facilitates the hoisting of the gas insulating sleeve 20. By adjusting the distance between the gas insulating sleeve 20 and the various components of the drilling device 100, collisions and damage to the gas insulating sleeve 20 during hoisting and transportation are avoided. Since the support mechanism 130 primarily supports the gas insulating sleeve 20, its movement along the length of the base 110 can be roughly adjusted manually, i.e., manually pushing the support mechanism 130 to slide along the two guide rails 113, as long as it stably supports the gas insulating sleeve 20. In other embodiments, a servo motor can be set to control the movement of the support mechanism along the length of the base, and a servo motor can be set to control the movement of the second bracket along the vertical direction to achieve automated operation and precise control of the movement distance. Details will not be elaborated further.

[0038] In this embodiment, there are two support mechanisms 130. Two support mechanisms 130 can more stably support the gas insulating sleeve 20, avoiding the instability that can occur when there is only one support mechanism 130 and it is not in the exact center of the gas insulating sleeve 20, which could lead to tilting and falling of the gas insulating sleeve 20. In other embodiments, when the length of the gas insulating sleeve is long, the number of support mechanisms is not limited and can be three or more, as long as they can support the gas insulating sleeve and maintain its balance.

[0039] See Figure 1 , Figure 8 and Figure 9The drilling mechanism 140 includes a body 141 and a drilling section 142. The drilling section 142 is mounted on the body 141, which also includes a display screen and an electrical connection structure. The display screen shows the working status and data information of the drilling mechanism 140, helping operators to adjust processing parameters in a timely manner and ensure processing results. The electrical connection structure provides power to the drilling section 142. The drilling section 142 includes a drilling head 1421, a first drilling module 1422, and a second drilling module 1423. The first drilling module 1422 drives the drilling head 1421 to move back and forth along the X-axis, and the second drilling module 1423 drives the drilling head 1421 to move back and forth along the Y-axis, enabling the drilling head 1421 to accurately position and drill holes at the end of the conductive rod 21. The X-axis is located in the horizontal plane and is perpendicular to the axis of the conductive rod 21, while the Y-axis is the vertical direction, meaning the X-axis is perpendicular to the Y-axis. Simultaneously, the axial direction of the punch head 1421 is defined as the Z-axis direction. The first punching module 1422 simultaneously drives the punch head 1421 to feed along the Z-axis direction, causing the punch head 1421 to perform a punching operation on the end of the conductive rod 21. Similarly, the second punching module 1423 can also simultaneously drive the punch head 1421 to feed along the Z-axis direction, details of which will not be elaborated further. The axial direction of the conductive rod 21 is parallel to the Z-axis direction.

[0040] Specifically, when operating the drilling mechanism 140, the target position coordinates, drilling / tapping mode, hole diameter, and other process parameters need to be pre-input into the display screen. The tool is changed synchronously, and after Z-axis tool setting, the quick-lock blocks below the first drilling module 1422 and the second drilling module 1423 are locked. The target point is selected to begin drilling, and the drilling unit 142 automatically positions itself for drilling. After drilling, it returns to the initial position to begin the next cycle. The operating area of ​​the machine body 141 is also equipped with interlocking devices such as a light grating and a safety door lock to prevent accidental activation by operators during drilling operations and facilitate timely stopping of the operation. The positioning accuracy of the drilling unit 142 reaches ±0.02mm, significantly improving drilling accuracy, ensuring product qualification rate, and eliminating the need to install and disassemble tooling for each product while automatically positioning and drilling. This simplifies the operation, reduces operating time, improves the operating method, and reduces operational risks.

[0041] Continue reading Figure 9 The drilling section 142 is further provided with a chip collection groove 1424. The chip collection groove 1424 is located below the drilling head 1421 and extends along the Z-axis to the outside of the body section 141, so that the chip collection groove 1424 can be used to receive metal chips that fall from the conductive rod 21 during drilling, thus preventing metal chips from falling on the ground or into the gap structure of the drilling device 100, which would be difficult to clean.

[0042] The working process of the drilling device 100 is as follows: Adjust the position of the support mechanism 130 to ensure that the support part 134 is set horizontally, place the gas insulating composite sleeve 20 on the support mechanism 130, push the support mechanism 130 to move the gas insulating composite sleeve 20 toward the positioning plate 121, and at the same time control the handwheel 135 to move the gas insulating composite sleeve 20 in the vertical direction until the conductive rod 21 can pass through the first through hole 1213 on the positioning plate 121. Then install the center positioning part 122 and the positioning pin 123 to realize the positioning and fixing of the flange of the gas insulating sleeve 20 and the conductive rod 21. By operating the drilling part 142, the end of the conductive rod 21 is drilled.

[0043] The beneficial effects of this application are as follows: Unlike the prior art, the drilling device of this application accurately positions the gas insulating sleeve by setting a positioning mechanism. At the same time, the positioning mechanism is applicable to various specifications of gas insulating sleeves, avoiding the phenomenon that each specification of product needs to be customized with positioning fixtures in the prior art. In addition, the use of a double-circuit drilling die allows for automatic positioning and drilling without the need to install and disassemble fixtures for each product, simplifying the operation steps, reducing the operation time, and the horizontal drilling method also improves the product operation mode and reduces the operation risk.

[0044] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
