Through tension, the grinding belt 305 forms a flat and elastic flexible grinding surface. The grinding belt 305 is made of flexible material, which can adapt to the curvature and angle difference of the edge of the insulator, so as to achieve full fit with the edge of different shapes and avoid grinding dead corners.

[0028] Through the structural design of the flexible grinding belt 305 and the wheel set, the grinding belt 305 can adapt to different edge shapes of the insulator, such as the arc edge, right angle edge, and stepped bevel edge, and fit tightly, improving the edge processing accuracy and surface flatness of the insulator; it can adapt to a variety of edge shapes without frequent replacement of the grinding head.

[0029] In one embodiment, it also includes: The base 100, and the support 200 are disposed on the base 100; A clamping fixture 102 is installed on the base 100 and is used to clamp the insulator; the clamping fixture 102 is set at the dot position of the base 100.

[0030] In one embodiment, the top of the base 100 is provided with an installation groove, in which a rotating base plate 101 is installed, and the support seat 200 is installed on the rotating base plate 101; a first gear 103 is sleeved on the rotating base plate 101, a first power source 105 is installed on the base 100, and a second gear 104 is installed on the power shaft of the first power source 105, and the second gear 104 meshes with the first gear 103.

[0031] Specifically, the first power source 105 uses a servo motor, but a stepper motor can also be used; both the mounting slot and the rotating base plate 101 are annular; the clamping fixture 102 is installed at the dot of the base 100, and its core function is to achieve centering and clamping of the insulator, so that the central axis of the insulator coincides with the rotation center of the rotating base plate 101, ensuring that the edge to be polished is on the same rotation circumference, providing a precise positioning reference for the surrounding polishing; the rotating base plate 101 rotates with the base 100 through the mounting slot, and the support seat 200 is fixed on the rotating base plate 101, so that the polishing assembly 300 can rotate synchronously with the rotating base plate 101; the first power source 105 provides rotational power, and the power is smoothly transmitted to the rotating base plate 101 through the meshing of the second gear 104 on the power shaft with the first gear 103 sleeved on the rotating base plate 101; the clamping fixture 102 fixes the position of the insulator, so that the flexible polishing belt 305 can continuously and evenly make close contact with various edge shapes of the insulator.

[0032] In one embodiment, the polishing assembly 300 further includes: a movable seat 301, an adjustment groove 201 is provided on one side of the support seat 200, the movable seat 301 is installed in the adjustment groove 201, a movable groove is provided at one end of the movable seat 301, and an adjustment seat 302 is installed in the movable groove; a second power source 203 is installed on the top of the support seat 200, a first lead screw 202 is connected to the power shaft of the second power source 203, and the first lead screw 202 is threadedly connected to the movable seat 301.

[0033] Specifically, the second power source 203 adopts a servo motor, or a stepper motor; the second power source 203 serves as a power output unit for radial adjustment, and its power shaft is fixedly connected to the first lead screw 202. The forward and reverse rotation of the second power source 203 drives the first lead screw 202 to rotate, and the threaded connection between the first lead screw 202 and the moving seat 301 converts the rotational motion into the linear motion of the moving seat 301 along the adjustment groove 201, thereby realizing the up and down movement of the grinding assembly 300.

[0034] In one embodiment, a third power source 307 is installed on the inner wall of the moving groove, and a second lead screw 308 is connected to the power shaft of the third power source 307. The second lead screw 308 is threadedly connected to the adjusting seat 302.

[0035] Specifically, the third power source 307 adopts a servo motor, or a stepper motor can also be used; the rotational power output by the third power source 307 is transmitted to the second lead screw 308 through the power shaft. The threaded connection between the second lead screw 308 and the adjusting seat 302 converts the rotational motion into the linear motion of the adjusting seat 302 along the moving groove, so that the adjusting seat 302 drives the grinding belt 305 to approach or move away from the edge of the insulator.

[0036] In one embodiment, the adjusting seat 302 has two connecting grooves on one side, the fixed wheel 303 is fixed in one of the connecting grooves, and the rotating wheel 304 is rotatably connected in the other connecting groove.

[0037] In a preferred embodiment, an elastic element 306 is installed on the adjusting seat 302, and the rotating wheel 304 is connected to the elastic element 306 via a rotating shaft; the elastic element 306 is a spring-loaded spring or a coil spring; by connecting the elastic element 306 on the adjusting seat 302 to the rotating shaft of the rotating wheel 304, the wear and stretching of the grinding belt 305 during long-term use or the deformation when adapting to different edge shapes can be automatically compensated, and the optimal tension of the grinding belt 305 can always be maintained.

[0038] In a preferred embodiment, the adjusting seat 302 has a recess formed on the side near the insulator to accommodate the edge of the insulator.

[0039] Working principle and usage process of this utility model: Place the base 100 in a stable working area, and clamp the insulator to be processed through the clamping fixture 102 at the dot of the base 100, so that the central axis of the insulator coincides with the rotation center of the rotating base plate 101. The third power source 307 is activated, which drives the second lead screw 308 to rotate, causing the adjusting seat 302 to move along the moving slot of the moving seat 301 towards the insulator until the edge of the insulator is embedded in the recess of the adjusting seat 302. At this time, the elastic element 306 on the adjusting seat 302 applies a preload to the rotating wheel 304 through the rotating shaft, keeping the grinding belt 305 between the fixed wheel 303 and the rotating wheel 304 taut and forming a flexible grinding surface that fits against the edge of the insulator. Subsequently, the first power source 105 is activated, and its power shaft drives the second gear 104 to rotate. The rotating base plate 101 is rotated by meshing with the first gear 103 on the rotating base plate 101. The rotating base plate 101 drives the support seat 200 to move around the insulator in a circumferential direction to realize the grinding action. During the process, the elastic element 306 automatically compensates for the tension changes caused by wear, stretching or edge deformation of the grinding belt 305. The second power source 203 is started, which drives the first lead screw 202 to rotate. Through the threaded connection, the moving seat 301 is driven to move up and down along the adjustment groove 201 of the support seat 200, so as to adjust the grinding position of the grinding belt 305.
