The core rod is mainly made of epoxy glass fiber, while the sheath and sheds are made of high-temperature vulcanized silicone rubber. To ensure the reliability of the connection between the insulator core rod and the sheds and fittings, the outer periphery and ends of the insulator core rod need to be ground. However, existing grinding devices for insulator core rods can only grind the outer periphery or ends of the insulator core rod.

[0040] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] This embodiment describes a grinding device for an insulator core rod. See [link to documentation]. Figure 1 , 4 As shown, the system includes a platform 1 and two support plates 2 symmetrically arranged on both sides of the platform 1. A second linear guide rail 3 is installed on the platform 1 at the bottom of each support plate 2 along the length of the support plate 2. The support plate 2 is installed inside the slide of the second linear guide rail 3. Two auxiliary rollers 4 for supporting the insulator core rod are correspondingly and rotatably installed on the inner front ends of the two support plates 2. Anti-fall blocks 5 are installed on the inner side of the support plate 2 above the auxiliary rollers 4 at the front ends. The insulator core rod to be ground is placed between the two support plates 2 and supported by the auxiliary rollers 4. To prevent axial displacement of the insulator core rod, a clamping mechanism is also correspondingly installed on the platform 1 on the outer front ends of the two support plates 2. (See [reference]). Figure 1 As shown, the clamping mechanism includes a first linear guide rail 6, a clamping rod 7 is mounted on the slide of the first linear guide rail 6, an opening corresponding to the clamping rod 7 and the insulator core rod is provided on the support plate 2, and a first drive cylinder 8 is mounted on the platform 1 to drive the slide of the first linear guide rail 6 and the clamping rod 7 to reciprocate linearly toward the end of the insulator core rod.

[0042] After the insulator core rod is placed, the slide of the first linear guide rail 6 is moved toward the support plate 2 by the first drive cylinder 8. The clamping rod 7 passes through the opening on the support plate 2 and acts on the insulator core rod. On the one hand, it can adjust the position of the insulator core rod, and on the other hand, it can apply a certain force to the insulator core rod. This force is small and can be sufficient to make the insulator core rod rotate under the action of external force without axial displacement.

[0043] A first grinding mechanism for grinding the outer circumference of the insulator core rod is mounted on the front end of the two support plates 2 via a gantry frame 9. In actual application, the two side plates of the gantry frame 9 can be fixed to the top of the two support plates 2; see [link to relevant documentation]. Figure 2 , 3 As shown, the first grinding mechanism includes a first servo drive module 10 arranged along the length of the insulator core rod. A first lifting device 11 is installed at the bottom of the slider of the first servo drive module 10. A fixed plate 12 is installed at the bottom of the first lifting device 11. Two dual-axis motors 13 are installed at the front and rear ends of the fixed plate 12. The execution axes of the two dual-axis motors 13 are also arranged along the length of the insulator core rod. In order to ensure that the entire outer periphery of the insulator core rod is ground, the length of the execution axis of the rear dual-axis motor 13 is greater than the length of the execution axis of the front dual-axis motor 13. Grinding wheels 14 are installed at the ends of the execution axes of the dual-axis motors 13.

[0044] The first lifting device 11 drives the dual-axis motor 13 to descend, so that the grinding wheel 14 comes into contact with the surface of the insulator core rod. The two dual-axis motors 13 drive the grinding wheel 14 to rotate in the same clockwise direction to grind the outer circumference of the insulator core rod. The friction force drives the insulator core rod to rotate so that the entire circumference can be ground. At the same time, the first servo module drives the dual-axis motor 13 to move slowly in the left and right directions so that the grinding wheel 14 can complete the grinding process of the entire insulator core rod.

[0045] A material ejection mechanism is provided on platform 1 between the two support plates 2 for retracting the insulator core rod, after its outer periphery has been ground, to the next work station. See [link / reference]. Figure 1 , 4As shown in Figure 5, the unloading mechanism includes two guide plates 15 symmetrically mounted on the platform 1. Slots 16 extending horizontally along the front and rear ends of the platform 1 are provided on the two guide plates 15. An unloading rod 17, with both ends passing through the slots 16 and fixedly connected to the corresponding support plate 2, is disposed between the two slots 16. A second drive cylinder 18, with its actuation shaft extending horizontally towards the rear end of the platform 1, is installed at the bottom of the platform 1. A guide plate 19 is vertically mounted at the end of the actuation shaft of the second drive cylinder 18. A waist-shaped hole 20 is provided on the platform 1 for the guide plate 19 to pass through and extends along the front and rear ends of the platform 1. The unloading rod 17 is fixedly connected to the top of the guide plate 19. The second drive cylinder 18 drives the guide plate 19 to reciprocate linearly along the waist-shaped hole, thereby causing the unloading rod 17 to follow the displacement. Both guide rod plates 15 have a first slope 21 that can lift the insulator core rod from the auxiliary roller 4 when the ejector rod 17 drives the support plate 2 and the insulator core rod to slide towards the rear end of the platform 1, and a second slope 22 that allows the insulator core rod to slide towards the rear end of the platform 1 after it is lifted; a receiving slot 23 is also provided on the guide rod plate 15 behind the second slope 22 for receiving the insulator core rod that slides down from the second slope 22.

[0046] After the outer circumference of the insulator is polished, the dual-axis motor 13 is lifted and the clamping rod 7 is reset. Then, the second drive cylinder 18 is started so that its execution shaft extends toward the rear end of the platform 1. At this time, the guide plate 19 will move toward the rear side of the waist-shaped hole and drive the ejector rod 17 to move backward. The movement of the ejector rod 17 causes the two support plates 2 to slide backward along the second linear guide rail 3. During the sliding process, the insulator core rod will be gradually lifted upward under the action of the first slope 21. Due to the presence of the anti-fall block 5, the insulator core rod will not slip. After being lifted further to the turning point of the first slope 21 and the second slope 22, the two ends of the insulator core rod will be separated from the support of the auxiliary rotating wheel 4. Therefore, under the action of gravity, it will slide down along the second slope 22 and finally fall into the receiving groove 23.

[0047] Then, the second drive cylinder 18 resets and drives the two support plates 2 back to their original positions, and the next insulator core rod to be ground is placed on the auxiliary rotating wheel 4 to perform the outer circumferential grinding operation.

[0048] A second grinding mechanism for aligning and grinding the ends of the insulator core rod is also provided on the platform 1 located on the outer rear end of the two guide rod plates 15. See [link to relevant documentation]. Figure 1 , 4As shown, the second grinding mechanism includes telescopic devices 24 symmetrically arranged outside the receiving slot 23. The extension shaft of the telescopic device 24 extends to align the insulator core rod that has slid into the receiving slot 23. A lifting mechanism is provided between the two guide plates 15 to lift the aligned insulator core rod. The lifting mechanism includes a third drive cylinder 25 vertically fixed below the platform 1. The end of the drive shaft of the third drive cylinder 25 is provided with a U-shaped lifting frame 26 distributed along the left and right ends of the platform 1. U-shaped grooves 27 for supporting the insulator core rod are opened at the top of both ends of the lifting frame. A square hole 28 is opened on the platform 1 for the U-shaped lifting frame 26 to pass through.

[0049] After the insulator core rod slips down, it is supported by the receiving groove 23 and the U-shaped groove 27. At this time, the two telescopic devices 24 are activated, and the actuator shafts of the two telescopic devices 24 extend simultaneously to act on the insulator core rod, thereby adjusting the position of the insulator core rod. Then, the third drive cylinder 25 is activated to drive the U-shaped frame and the insulator core rod to lift.

[0050] A positioning block 29 is mounted above each telescopic device 24. The front end of the positioning block 29 has a limiting port 30 that can limit the end of the insulator core rod after it is lifted. A fourth drive cylinder 31 is installed on one side of each positioning block 29. A small grinder 32 is fixed to the end of the actuation shaft of the fourth drive cylinder 31 through a connecting plate. A through hole 33 is also provided on the positioning block 29 for the grinder 32 to pass through.

[0051] After the third drive cylinder 25 lifts the insulator core rod, the upper surface of the insulator core rod will enter the limiting port 30 and be restricted by the limiting port 30 from moving further upward. At this time, the fourth drive cylinder 31 drives the grinding machine 32 to move towards the end of the insulator core rod and starts the grinding machine 32, so that the execution end of the grinding machine 32 contacts the end of the insulator core rod and grinds the end of the insulator core rod. After grinding is completed, the grinding machine 32 retracts into place.

[0052] Furthermore, the grinding device also includes a pull-out bearing mechanism for pulling out the insulator core rod after end grinding; the pull-out bearing mechanism includes a lever 34, a carrier rod 35, and a receiving plate 36. Multiple levers 34 and carrier plates are provided. The lever 34 is located inside the two guide rod plates 15, and the carrier plate is fixed to the rear end of the lever 34. The receiving plate 36 is fixed to the rear end of the carrier rod 35. The positioning block 29 is mounted above each telescopic device 24 through an L-shaped bracket 37 fixed on the rear platform 1 of the telescopic device 24, and a fixing block 38 is installed on the rear side of the L-shaped bracket 37. A first fixing shaft 39 passes through the front end of the carrier plate, and the two ends of the first fixing shaft 39 are rotatably connected to the fixing block 38 on the corresponding side. A second fixing shaft 40 passes through the rear end of the carrier plate, and a fifth drive cylinder 41 is provided on the rear side of the platform 1. The bottom end of the fifth drive cylinder 41 is hinged to the fixing seat 49 below, and the execution end is hinged to the second fixing shaft 40.

[0053] Initially, the lever 34 is tilted downwards and faces the inner side of the two guide plates 15. After the end of the insulator core rod is polished, the third drive cylinder 25 drives the insulator core rod supported on the U-shaped lifting frame 26 to descend. During the descent of the insulator core rod, both ends of the insulator core rod are released from the restriction port 30. The fifth drive cylinder 41 is activated, causing its actuating shaft to extend and thus gradually lift the lever 34 upwards. During the lifting of the lever 34 and the descent of the insulator core rod, the insulator core rod can be pulled out of the U-shaped groove 27 and slide down the carrying rod 35 into the receiving plate 36. After the insulator core rod is pulled out, the third drive cylinder 25 retracts to its original position.

[0054] Furthermore, the grinding device also includes a feeding mechanism for removing insulators that have slid into the receiving tray 36; the feeding mechanism includes a support frame 42, and a second servo drive module 43 arranged along the front and rear end direction is installed on the lower part of the top layer of the support frame 42; a second lifting device 44 with the actuation axis vertically downward is installed under the slide of the second servo drive module 43; a pneumatic or electric gripping mechanical claw 45 is installed at the end of the actuation axis of the second lifting device 44, and a holding frame 46 is placed inside the support frame 42.

[0055] After the polished insulator core rod slides into the receiving tray 36, the second servo drive module 43 moves the gripping mechanical claw 45 above the insulator core rod. Then, the second lifting device 44 moves the gripping mechanical claw 45 downward and opens it during the downward movement. After the gripping mechanical claw 45 reaches its lower position, the insulator core rod is within the range of the gripping mechanical claw 45. The gripping mechanical claw 45 grips the core rod tightly, and the second lifting device 44 moves upward. The second servo drive module 43 moves it to the rearward position. After moving above the holding frame 46, the second lifting device 44 moves the gripping mechanical claw 45 downward and opens it, allowing the insulator core rod to fall into the holding frame 46. Then, the fifth drive cylinder 41 drives the lever 34, the transport rod 35, and the receiving tray 36 to reset.

[0056] Two third linear guides 47 are symmetrically installed at the bottom of the holding frame 46, arranged along the front-to-rear direction. The holding frame 46 is fixedly connected to the slides of the two third linear guides 47. A third servo drive module 48 is installed between the two third linear guides 47 along the front-to-rear direction, and the holding frame 46 is also fixedly connected to the slide of the third servo drive module 48. After placing a certain number of polished insulator core rods in the holding frame 46, the third servo drive module 48 is activated, causing it to move the holding frame 46 relative to the third linear guides 47 to the rear, preventing workers from removing the processed insulator core rods. After removal, the third servo drive module 48 drives the holding frame 46 to reset.

[0057] In this embodiment, the platform 1, the third drive cylinder 25, the fixed base 49, and the support frame 42 are all fixed to the ground by support members or fasteners.

[0058] The grinding device provided by this invention integrates a first grinding mechanism for grinding the outer circumference of the insulator core rod and a second grinding mechanism for grinding the end of the insulator core rod. By incorporating a material ejection mechanism, it achieves automatic transition from the outer circumference grinding station to the end grinding station, avoiding manual replacement of the insulator core rod position and effectively improving grinding efficiency. The second grinding mechanism includes a telescopic device 24 with a positioning function and a lifting mechanism. The telescopic device 24 can correct the position of the insulator core rod, ensuring the operability and accuracy of subsequent end grinding; the lifting mechanism lifts the aligned insulator core rod to the end grinding station, facilitating the grinding operation. By setting up a pull-out bearing mechanism, the polished insulator core rods can be pulled out from platform 1, reducing manual intervention and facilitating automation. At the same time, by setting up a feeding mechanism, the polished insulator core rods in the receiving plate 36 can be taken out and placed in a centralized container. By setting up a linear module and a servo drive module, the container frame 46 can be moved out, reducing manpower and material resources and improving processing efficiency.

[0059] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
