Description

Technical Field

[0001] The invention relates to the technical field of arrester production and processing, and in particular to a porcelain jacket arrester end cover spinning device. Background Art

[0002] Porcelain-coated metal oxide arrester (hereinafter referred to as MOA) is a protective device used to protect the power transmission and transformation station equipment, capacitor banks, and motor neutral points of the power system from atmospheric overvoltage and operating overvoltage damage. It has the advantages of small size, light weight, good sealing, large current flow energy, and good nonlinearity. The MOA uses a nonlinear metal oxide resistor as the core component, which has excellent volt-ampere characteristics. When the system has atmospheric overvoltage or operating overvoltage, the resistor presents low resistance, so that the residual voltage of the MOA is limited to below the allowable value, while absorbing the overvoltage energy, thereby providing reliable protection for the power equipment. Under the normal operating voltage of the MOA, the resistor presents high resistance, so that the current flowing through the MOA is very small, which plays the role of insulation and isolation from the system.

[0003] MOA is usually composed of a porcelain sleeve, a resistor group, an end cap and other components. The sealing problem of the end cap has long been a concern of people. During the MOA assembly process, the end cap needs to be tightly put on the outer surface of the end of the porcelain sleeve and ensure good sealing to prevent water vapor from invading the interior of the porcelain sleeve. To this end, after the end cover is put on the outer surface of the end of the porcelain sleeve, it is necessary to use a spinning machine to spin the end cover installed on the end of the porcelain sleeve so that the side wall of the end cover is tightly fitted to the outer surface of the end of the porcelain sleeve. Although this method can solve the sealing problem of the end cover to a certain extent, due to the radial size differences of different porcelain sleeves during production, the spinning force must be controlled at the same time during spinning to avoid the porcelain sleeve from cracking due to a sudden increase in the spinning force when the spinning wheel of the spinning machine is in rigid contact with the porcelain sleeve, and to avoid the problem of poor sealing of the end cover even when the spinning force is small. Therefore, the spinning process is usually arranged for experienced masters to perform manual spinning operations. However, in actual operation, it is also difficult to reasonably control the spinning force to ensure that the spinning work can be completed in only one operation. It is often necessary to rework many times and complete the spinning operation of a lightning arrester after passing the measurement, which seriously affects the production efficiency. Summary of the invention

[0004] Based on the above-mentioned problems existing in the prior art, the present invention aims to solve the technical problem in the prior art that it is difficult to reasonably control the spinning force to ensure that the spinning operation can be completed in only one operation when using a spinning machine to spin the end cover mounted on the outer surface of the end of the porcelain sleeve of the lightning arrester.

DETAILED DESCRIPTION

[0038] The following descriptions of the embodiments refer to the attached drawings to illustrate specific embodiments in which the present invention can be implemented.

[0039] The present invention provides a porcelain jacket arrester end cap spinning device, the structure of the porcelain jacket arrester 100 is as follows Figure 1 and Figure 2 As shown, the porcelain jacket arrester 100 comprises a porcelain jacket 101, an end cover 102 and a spring 103; the structure of the porcelain jacket arrester end cover spinning device is as shown in Figure 3 and Figure 4 As shown, it includes a positioning and rotating mechanism 1, a spinning mechanism 2 and a distance measuring element 3, wherein the positioning and rotating mechanism 1 is used to position the porcelain jacket arrester 100 to be processed and drive it to rotate around its central axis; the spinning mechanism 2 includes a roller 21, an elastic member 22 and a telescopic driving assembly 23 connected in sequence, wherein the telescopic driving assembly 23 is used to drive the roller 21 to approach or move away from the porcelain jacket arrester 100 to be processed, and the elastic member 22 is used to buffer the thrust of the telescopic driving assembly 23 on the roller 21, And absorb part of the displacement of the telescopic drive assembly 23; the distance measuring element 3 is used to measure the distance between the edge of the roller 21 and the surface of the porcelain jacket 101 of the porcelain jacket arrester 100 to be processed; when the distance value measured by the distance measuring element 3 reaches a preset distance value, the telescopic drive assembly 23 stops feeding, wherein the preset distance value is the distance value between the edge of the roller 21 and the surface of the porcelain jacket 101 of the porcelain jacket arrester 100 when the side wall of the end cover 102 of the porcelain jacket arrester 100 is tightly fitted to the surface of the porcelain jacket 101.

[0040] like Figure 2 The figure shows a cross-sectional view of a porcelain jacket arrester 100. Since the porcelain jacket 101 has a spring 103 ( Figure 2 The spring 103 in it is in a compressed state), and the original length of the spring 103 is relatively long. When the end cover 102 is covered on the end of the porcelain jacket 101, it is necessary to overcome the elastic force of the spring 103 to compress it; therefore, the positioning and rotating mechanism 1 includes a rotating seat 11, a clamping assembly 12 and a second rotating drive member (not shown in the figure), wherein the rotating seat 11 is used to place the porcelain jacket arrester 100 to be processed; the clamping assembly 12 is used to press the porcelain jacket arrester 100 on the rotating seat 11, and at the same time, the end cover 102 can be covered on the end of the porcelain jacket arrester 100 by the pressure of the clamping assembly 12, and the rotating seat 11 can drive the porcelain jacket arrester placed thereon to rotate by friction; the second rotating drive member is used to drive the rotating seat 11 to rotate, and specifically, the second rotating drive member can be a motor.

[0041] For further information, please refer to Figure 3In order to prevent the porcelain jacketed lightning arrester 100 from moving due to the thrust of the spinning mechanism 2, a positioning groove 110 with a shape matching the shape of the end cover 102 is opened at the center of the rotating seat 11, which is used to position the porcelain jacketed lightning arrester 100 in its radial direction, and the depth of the positioning groove 110 is less than the thickness of the end cover 102, so that the top end of the end cover 102 can protrude from the positioning groove 110, so that the spinning mechanism 2 can spin the part of the end cover 102 protruding from the positioning groove 110.

[0042] Specifically, the clamping assembly 12 includes a lifting drive member 121 and a pressure plate 122, wherein the lifting drive member 121 is fixedly arranged directly above the rotating seat 11, and specifically, the lifting drive member 121 can be a cylinder or a hydraulic cylinder; the pressure plate 122 is rotatably connected to the end of the piston rod of the lifting drive member 121, and when the pressure plate 122 presses the porcelain jacket arrester 100, the rotating porcelain jacket arrester 100 can drive the pressure plate 122 to rotate, thereby avoiding direct contact between the rotating porcelain jacket arrester 100 and the piston rod of the lifting drive member 121 and causing wear; in addition, since the top of the porcelain jacket arrester 100 is usually also provided with bolts and other parts, in order to enable the pressure plate 122 to effectively fit with the porcelain jacket 101 of the porcelain jacket arrester 100, a matching groove (not shown in the figure) matching the shape of the end of the porcelain jacket arrester 100 is provided on the end face of the pressure plate 121 close to the rotating seat 11.

[0043] When it is necessary to perform spinning operations on porcelain jacketed lightning arresters 100 of different lengths with a small length difference, this can be achieved by adjusting the extended length of the piston rod of the lifting drive 121; when it is necessary to perform spinning operations on porcelain jacketed lightning arresters 100 of different lengths with a large length difference (the length difference between porcelain jacketed lightning arresters 100 of different specifications exceeds the stroke of the piston rod of the lifting drive 121), this can be achieved by adjusting the installation height of the lifting drive 121, for example, the lifting drive 121 can be fixed on a fixed frame that can be lifted and lowered.

[0044] like Figure 4 Shown Figure 3 The structural diagram after removing the pressing assembly 12, in this embodiment, the spinning mechanism 2 further includes an electrically connected force measuring element 24 and a drawing module 25, and the force measuring element 24 is arranged between the roller 21 and the elastic member 22 or between the elastic member 22 and the telescopic driving member 23;

[0045] When the distance value measured by the distance measuring element 3 reaches the preset distance value, the force measuring element 24 starts to measure the pressure value of the porcelain sheathed lightning arrester 100, and the drawing module 25 draws a force value curve in real time according to the measurement result of the force measuring element 24. The force value curve is used as a basis for judging whether the end cover 102 is spun uniformly. Specifically, when the force value curve is displayed as a straight line at a certain moment, it indicates that the end cover 102 has been spun uniformly at that moment.

[0046] It is not difficult to understand that when the end cover of the porcelain jacketed lightning arrester 100 is not fully spun, the side wall surface of the end cover 102 will be uneven, and when the end cover 102 of the porcelain jacketed lightning arrester 100 is spun into place, the side wall surface of the end cover 102 should be a smooth curved surface. At this time, no matter where the roller 21 contacts the circumferential side wall of the end cover 102, the measurement result of the force measuring element 24 should be consistent, and the force value curve drawn by the drawing module 25 should be a horizontal straight line. Therefore, by observing the shape of the force value curve drawn by the drawing module 25, it is possible to more intuitively judge whether the spinning state of the end cover 102 is qualified, which has higher accuracy than observing the spinning state of the end cover 102 by naked eye in the prior art.

[0047] Furthermore, the spinning mechanism 2 also includes a roller seat 26, the roller 21 is rotatably set on the roller seat 26, and the rotation axis is parallel to the central axis of the rotating seat 11, and the distance measuring element 3 is fixedly set on the roller seat 26; the force measuring element 25 is set between the roller seat 26 and the elastic member 22 or between the elastic member 22 and the output end of the telescopic drive assembly 23.

[0048] It should be noted that setting the distance measuring element 3 on the roller seat 26 is a better installation position for the distance measuring element 3. At this time, the preset distance value is the sum of the distance value from the edge of the roller 21 to the surface of the porcelain jacket 101 of the porcelain jacket arrester 100 when the side wall of the end cover 102 of the porcelain jacket arrester 100 is tightly fitted to the surface of the porcelain jacket 101 and the distance from the distance measuring element 3 to the edge of the roller 21.

[0049] In this embodiment, the porcelain jacket arrester end cover spinning equipment also includes a workbench 4, and the telescopic drive assembly 23 includes a first frame 231, a screw pair 232 and a first rotating drive member 233, wherein the first frame 231 is fixedly arranged on the workbench 4; the screw pair 232 includes a screw 2321 and a nut 2322 that are meshed with each other, one end of the screw 2321 is rotatably installed on the first frame 231, and the nut 2322 is axially slidably arranged on the upper surface of the workbench 4 along the screw 2321; the two ends of the elastic member 22 are respectively fixedly connected to the nut 2322 and the roller seat 26, specifically, the elastic member 22 can be a spring; the output end of the first rotating drive member 233 is fixedly connected to the screw 2321, specifically, the first rotating drive member 233 is a hand-cranked wheel.

[0050] Specifically, in order to enable the nut 2322 to slide axially along the screw rod 2321 on the upper surface of the workbench 4, the telescopic drive assembly 23 also includes a sliding pair 234, and the sliding pair 234 includes a sliding seat 2341 and a slider 2342 that are slidably matched. The sliding seat 2341 is fixedly arranged on the upper surface of the workbench 4, and the slider 2342 is fixedly connected to the nut 2322.

[0051] Furthermore, the spinning mechanism 2 further comprises a sleeve 27 , one end of which is fixedly connected to the roller seat 26 , and the other end of which is movably sleeved on the outer surface of one end of the screw rod 2321 away from the first rotating driving member 233 .

[0052] It can be understood that the two ends of the elastic member 22 are fixedly connected to the nut 2322 and the roller seat 26 respectively. Since the elastic member 22 is difficult to withstand the lateral torque perpendicular to its length direction, the sleeve 27 is fixedly set on the roller seat 26, and the sleeve 27 is movably mounted on the outer surface of the end of the screw rod 2321 away from the first rotating drive member 233. The screw rod 2321 can support the roller seat 26 through the sleeve 27. At the same time, the sleeve 27 and the screw rod 2321 can flexibly cooperate to guide the moving roller seat 26.

[0053] Furthermore, the spinning mechanism 2 also includes a support seat 28 fixedly arranged on the workbench 4, and the outer surface of the sleeve 27 is slidably matched with the support seat 28 so that the sleeve 27 can slide along the axial direction of the screw rod 2321. The support seat 28 can provide supporting force to the sleeve 27, thereby improving the reliability of the spinning mechanism 2.

[0054] In order to facilitate the understanding of this scheme, the following Figure 1-Figure 6 The working principle of the present invention is described in detail:

[0055] In the first step, the end of the porcelain jacket arrester 100 with the end cover 102 is placed downward in the positioning groove 110 of the rotating seat 11. Since the shape of the positioning groove 110 matches the shape of the end cover 102, the porcelain jacket arrester 100 can be positioned radially. At this time, under the elastic force of the spring 103, the bottom end of the porcelain jacket 101 is suspended directly above the end cover 102. The lifting drive member 121 is manipulated to extend its piston rod downward, and at the same time drive the pressure plate 122 to move downward to apply a downward pressure to the top of the porcelain jacket 101. During this period, the spring 103 will gradually shrink after being subjected to pressure until the bottom end of the porcelain jacket 101 is pressed against the end cover 102. At this time, the end cover 102 is movably sleeved on the outer surface of the bottom end of the porcelain jacket 101.

[0056] Step 2, operate the first rotating drive member 233 to drive the screw rod 2321 to rotate. Since the screw rod 2321 is threadedly matched with the nut 2322, and the nut 2322 is slidably set on the upper surface of the workbench 4 through the sliding pair 234, the nut 2322 will approach the porcelain jacket arrester 100. When the nut 2322 moves close to the porcelain jacket arrester 100, the elastic member 22 is gradually compressed. During this period, the elastic member 22 will buffer the thrust transmitted to the roller seat 26 by the nut 2322 and absorb part of the displacement of the nut 2322, so that the roller seat 26 pushes the roller 21 toward the porcelain jacket arrester 100 at a relatively small speed until the outer circumferential edge of the roller 21 contacts the part of the end cover 102 protruding from the positioning groove 110.

[0057] When the roller 21 contacts the end cover 102, the roller 21 starts to spin the side wall of the end cover 102, and as the screw pair 232 continues to feed, the distance between the inner wall of the end cover 102 and the outer surface of the ceramic jacket 101 gradually decreases, so that the distance between the distance measuring element 3 and the surface of the ceramic jacket 101 gradually decreases.

[0058] Step 3, when the distance value measured by the distance measuring element 3 reaches the preset distance value, the screw pair 232 stops feeding (the nut 2322 remains at the position at this time), and at the same time, the force measuring element 24 starts to measure the pressure value of the porcelain jacket arrester 100, and the drawing module 25 draws the force value curve in real time according to the measurement result of the force measuring element 24;

[0059] At the moment when the distance value measured by the distance measuring element 3 reaches the preset distance value, only the local position where the end cover 102 contacts the roller 21 is spun into place in the circumferential direction of the end cover 102, and other circumferential positions need to continue to be spun; at the same time, since the screw pair 232 stops feeding thereafter, the measurement result of the force measuring element 24 is the smallest during the subsequent period of time, and with the continuous spinning of the end cover 102, the force value measured by the force measuring element 24 is constantly changing until the circumference of the end cover 102 is spun into place. When the end cover 102 is fully spun, since the outer surface of the side wall of the top end of the end cover 102 is a smooth curved surface, the force value measured by the force measuring element 24 will not change with the rotation of the end cover 102. After the distance value measured by the distance measuring element 3 reaches the preset distance value, the Ft curve drawn by the drawing module 25 according to the measurement result of the force measuring element 24 is as shown in FIG. Figure 6 As shown; it is not difficult to understand that when the measurement result of the force measuring element 24 does not change with time, the circumference of the end cover 102 has been spun into place. At this time, the roller 21 can be withdrawn, and the spinning mechanism 2 and the positioning rotating mechanism 1 can be closed, and the porcelain jacket arrester can be removed.

[0060] Compared with the prior art, the present invention provides a spinning device for a porcelain jacket arrester end cap, in which an elastic member 23 is arranged between the roller 21 of the spinning mechanism 2 and the telescopic drive assembly 23. The elastic member 23 can buffer the thrust of the telescopic drive assembly 23 on the roller 21 on the one hand, thereby preventing the roller 21 from generating a huge thrust acting on the surface of the porcelain jacket 101 and causing the porcelain jacket 101 to break when the telescopic drive assembly 23 is fed, and can absorb part of the displacement of the telescopic drive assembly 23, so that the feeding speed of the roller 21 is less than that of the telescopic drive assembly 23. The moving speed of the output end of the drive component 23; in addition, the telescopic drive component 23 can perform a feeding operation according to the measurement value of the ranging element 3. Specifically, when the side wall of the end cover 102 of the porcelain jacket arrester 100 is tightly fitted to the surface of the porcelain jacket 101, the measurement value of the ranging element 3 reaches a preset distance value, and the feeding can be stopped. Compared with the prior art that relies on experience to judge whether the end cover 102 of the porcelain jacket arrester 100 is spun into place, which requires multiple reworks, this solution only requires one operation, which greatly improves the spinning efficiency of the end cover 102 of the porcelain jacket arrester 100.

[0061] It should be noted that although the present invention is disclosed as above by specific embodiments, the above embodiments are not intended to limit the present invention. Ordinary technicians in this field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
