Description

Technical Field

[0001] This utility model relates to the field of grinding technology for three-post insulators, and in particular to a grinding device. Background Technology

[0002] Three-post insulators are key insulating components in high-voltage transmission systems. Their main function is to support and isolate high-voltage current, ensuring the safe and stable operation of the power system. A crucial process in the production of these insulators is grinding. Technicians use specialized grinding equipment to meticulously grind the outer walls of the insulator posts, the insulator itself, and the center cylinder, creating specific grinding areas to reduce burrs and lower the electric field strength in these critical areas, thereby significantly improving the overall insulation performance margin.

[0003] When grinding the outer walls of the posts and the outer walls of the insulators of a three-post insulator, the central cylinder of the insulator is usually clamped by a fixing component in the grinding device, thus fixing the insulator to the grinding device. After the outer walls of the posts and the outer walls of the insulators are ground, the three-post insulator needs to be removed and the outer walls of the insulator re-fixed by the fixing component. At this time, the three-post insulator needs to be repositioned, which requires sufficient time. This increases the grinding time of the three-post insulator and reduces the grinding efficiency. Utility Model Content

[0004] In view of the problem that the existing technology of repositioning the three-post insulator increases the grinding time of the three-post insulator, this utility model is proposed.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a grinding device that can quickly grind the outer wall of the support, the outer wall of the insulator, and the outer wall of the center cylinder of a three-post insulator.

[0030] Specifically, the support assembly 100 includes a support frame 101, a fixed table 102 connected to one side of the support frame 101, and a support frame 105 connected to the other side of the support frame 101, wherein the support frame 101, the fixed table 102, and the support frame 105 are integrated into one unit.

[0031] A first motor 103 is fixedly connected to the top of the fixed table 102. A grinding wheel 104 is provided at the output end of the first motor 103. The grinding wheel 104 faces the rotating ring 201. The first motor 103 is a chamfering grinding wheel motor with model UAMZ90L-2.

[0032] In summary, when it is necessary to polish the three-post insulator, the three-post insulator is fixed in place, and then the first motor 103 is started to drive the polishing wheel 104 to rotate and polish the outer wall of the three-post insulator.

[0033] Example 2

[0034] Reference Figures 1-6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the first rotating frame 204c, the linkage frame 204d, and the second rotating frame 205d can switch the fixing method at the central circular hole of the three-post insulator and at the outer wall of the three-post insulator without removing the three-post insulator.

[0035] The fixing component 200 is disposed on the support frame 105 and includes a rotating ring 201, a fixing rod 202 connected to one side of the rotating ring 201, a support ring 203 connected to one side of the fixing rod 202, a rotating component 204 connected to the outer wall of the support ring 203, and a driving component 205 connected to the outer wall of the support ring 203. There are several rotating components 204, and the several rotating components 204 are circularly disposed on the outer wall of the support ring 203. The driving component 205 is connected to the rotating component 204 located at the edge. A set of rotating components 204 and driving components 205 are disposed on the upper and lower outer walls of the support ring 203. There is no connection between these two sets of rotating components 204 and driving components 205.

[0036] Both the rotating ring 201 and the support ring 203 are circular in shape.

[0037] The top of the support frame 105 is semi-circular, and the top of the support frame 105 is provided with a groove whose outer wall has the same cross-sectional shape as the rotating ring 201. The groove on the top of the support frame 105 is slidably connected to the outer wall of the rotating ring 201. When the rotating ring 201 is pushed, the rotating ring 201 will drive the support ring 203, the rotating component 204 and the driving component 205 to rotate.

[0038] The rotating component 204 includes a first fixed tube 204a, a first rotating block 204b rotatably connected to the outer wall of the first fixed tube 204a, a first rotating frame 204c rotatably connected to the outer wall of the first rotating block 204b, and a linkage frame 204d rotatably connected to one side of the first rotating frame 204c. Two symmetrical first rotating frames 204c are rotatably connected to the outer wall of the first rotating block 204b, and the linkage frame 204d is connected to the other side of each of the two first rotating frames 204c.

[0039] The inner wall of the first fixed tube 204a is connected to the outer wall of the support ring 203. The cross-sectional shape of the first rotating block 204b is hexagonal, and the shape of the first rotating frame 204c is T-shaped. An arc-shaped groove is provided on one side of the first rotating frame 204c. The first rotating frame 204c is located on one side of the first rotating block 204b. The first rotating block 204b can be rotated by pushing the first rotating frame 204c.

[0040] A second motor 206 is provided on the outer wall of the fixed rod 202. A gear 207 is provided at the output end of the second motor 206. The second motor 206 and the gear 207 are arranged at an angle. The second motor 206 is a medium-sized 24V micro DC motor of model Z3D30-24A1. There are two of both the second motor 206 and the gear 207.

[0041] The driving component 205 includes a second fixed tube 205a, a second rotating block 205b rotatably connected to the outer wall of the second fixed tube 205a, a gear disk 205c disposed on one side of the second rotating block 205b, and a second rotating frame 205d rotatably connected to the outer wall of the second rotating block 205b, wherein only one second rotating frame 205d is disposed on the second rotating block 205b.

[0042] The inner wall of the second fixed tube 205a is connected to one side of the support ring 203. The shape of the second rotating block 205b is the same as that of the first rotating block 204b. The shape of the second rotating frame 205d is the same as that of the first rotating frame 204c. The second rotating frame 205d is located on one side of the second rotating block 205b and is on the same horizontal plane as the first rotating frame 204c.

[0043] The outer wall of gear 207 meshes with the outer wall of gear disk 205c. One side of the second rotating frame 205d is rotatably connected to one side of the outer wall of linkage frame 204d. The linkage frame 204d is bow-shaped. As mentioned above, each rotating component 204 in the same group is connected through the first rotating frame 204c. In this way, the first rotating frame 204c, linkage frame 204d and second rotating frame 205d can form a semicircle.

[0044] When the second motor 206 drives the gear 207 to rotate, the gear disk 205c will rotate accordingly. At this time, the second rotating block 205b will drive the second rotating frame 205d to rotate around the supporting second fixed tube 205a. When the second rotating frame 205d rotates, it will drive the linkage frame 204d to move. When the linkage frame 204d moves, it will drive the first rotating frame 204c to rotate. When the first rotating frame 204c rotates, it will drive the first rotating block 204b to rotate. At this time, the other first rotating frame 204c on the first rotating block 204b will also rotate due to the influence of the first rotating block 204b, thereby causing the other rotating parts 204 to rotate as well.

[0045] It should be noted that the first rotating block 204b is rotatably connected to the first rotating frame 204c. Therefore, when the first rotating frame 204c rotates around the first fixed tube 204a, the angle between it and the first rotating frame 204c changes. As a result, the angle of the linkage frame 204d between the two first rotating frames 204cs also moves. Finally, after the gear 207 rotates a certain number of times, the first rotating frame 204c, the linkage frame 204d, and the second rotating frame 205d will rotate around the support ring 203 one revolution.

[0046] As described above, the visible effect of these functions is that when it is necessary to polish the outer wall of the three-post insulator, the three-post insulator is fitted onto the first rotating frame 204c, the linkage frame 204d, and the second rotating frame 205d. Then, the second motor 206 is started to make the gear 207 rotate clockwise, which drives the first rotating frame 204c, the linkage frame 204d, and the second rotating frame 205d to rotate from the inner ring of the support ring 203 toward the first motor 103. In this way, the first rotating frame 204c, the linkage frame 204d, and the second rotating frame 205d can be spread apart, and the first rotating frame 204c, the linkage frame 204d, and the second rotating frame 205d can squeeze the inner ring of the three-post insulator. When the first rotating frame 204c, the linkage frame 204d, and the second rotating frame 205d on both the upper and lower sides of the support ring 203 squeeze the outer wall of the middle circular hole of the three-post insulator, the three-post insulator can be fixed on the fixing component 200. At this time, the outer wall of the three-post insulator can be polished.

[0047] Simultaneously, when it is necessary to grind the center circular hole of the three-post insulator, one of the second motors 206 is started to drive the gear 207 to rotate counterclockwise. This causes any one of the first rotating frames 204c, linkage frame 204d, and second rotating frame 205d on the upper and lower sides of the support ring 203 to rotate away from the first motor 103. In this way, the side of the first rotating frame 204c and the second rotating frame 205d with the arc-shaped groove rotates towards the outer wall of the three-post insulator. Finally, the side of the first rotating frame 204c and the second rotating frame 205d with the arc-shaped groove rotates towards the outer wall of the three-post insulator. One side contacts and squeezes the outer wall of the three-post insulator, clamping the three-post insulator from the direction of the outer wall of the three-post insulator. At this time, another second motor 206 is started to drive another gear 207 to rotate counterclockwise, causing another set of first rotating frames 204c, linkage frames 204d and second rotating frames 205d on the upper and lower sides of the support ring 203 to rotate away from the first motor 103, thereby fixing the fixing component 200 from the outer wall of the three-post insulator. At this time, the grinding work can be carried out on the center of the three-post insulator.

[0048] In summary, the first rotating frame 204c, the linkage frame 204d, and the second rotating frame 205d can switch the fixing method at the central circular hole and the outer wall of the three-post insulator without removing the three-post insulator, thereby improving the grinding efficiency of the three-post insulator.

[0049] Example 3

[0050] Reference Figures 1-6 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the polishing effect of the polishing device can be increased by adding an existing drive component.

[0051] The support assembly 100 includes a support frame 101, a fixed table 102 connected to one side of the support frame 101, and a support frame 105 connected to the other side of the support frame 101. A first motor 103 is fixedly connected to the top of the fixed table 102. A grinding wheel 104 is provided at the output end of the first motor 103, and the grinding wheel 104 faces the rotating ring 201. A corresponding drive assembly is installed on the fixed table 102, and the first motor 103 is driven to move in other directions by a conveying device. In this way, the position of the first motor 103 can be adjusted according to the shape of the three-post insulator.

[0052] In summary, a drive assembly can be installed on the fixed table 102 to drive the first motor 103 and the grinding wheel 104 to adjust their positions according to the shape of the three-post insulator, thereby improving the grinding effect.
