Description

Technical Field

[0001] This utility model relates to the field of insulator processing technology, specifically to a jig for processing crossarm insulators. Background Technology

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. Insulators come in many types and shapes. Although the structure and appearance of different types of insulators vary considerably, they all consist of two main parts: insulating components and connecting hardware. An insulator is a special type of insulating control that plays a crucial role in overhead transmission lines. In earlier times, insulators were mostly used on utility poles. Gradually, they evolved into the use of disc-shaped insulators hung at one end of high-voltage power line towers to increase creepage distance; these are typically made of glass or ceramic and are called insulators.

[0003] Existing technologies have the problem that they cannot clamp crossarm insulators of different sizes during the processing and clamping of crossarm insulators. This results in the device being able to clamp only one size of insulator, reducing the applicability of the device. At the same time, after clamping corresponding insulators in the same group, the concentricity of the two insulators cannot be guaranteed. Ultimately, this leads to the inability to clamp different types of insulators at the same time, reducing the processing efficiency of the device. To address this, we propose a jig for processing crossarm insulators. Utility Model Content

[0023] In this embodiment, a mounting bracket 41 is fixedly connected to the middle of the front end of the workbench 1. A stepper motor 42 is fixedly connected to the inner end of the mounting bracket 41. A rotating rod 43 is fixedly connected to the output end of the stepper motor 42. Two symmetrically arranged threaded grooves are opened on the outer periphery of the rotating rod 43. A moving plate 44 is threadedly connected to the outer surface of the rotating rod 43 and the rotating rod 43 passes through the moving plate 44. The lower end of the moving plate 44 is slidably connected to the workbench 1. A fixed seat 461 is fixedly connected to the front end face of each moving plate 44.

[0024] Specifically, the stepper motor 42 drives the rotating rod 43 to rotate, which in turn drives the moving plate 44 to move closer to each other.

[0025] In this embodiment, the rear ends of the two arc-shaped plates 462 are fixedly connected to the fixed base 461, and the electric push rod 467 is fixedly connected to the moving plate 44.

[0026] Specifically, ensure that the curved plate 462 can move smoothly.

[0027] In this embodiment, a power supply 2 and a controller 3 are fixedly connected to the front end of the workbench 1, and the power supply 2 and the controller 3 are located on both sides of the stepper motor 42.

[0028] Specifically, the stepper motor 42 and the electric push rod 467 can be powered and controlled smoothly through the power supply 2 and the controller 3.

[0029] In this embodiment, two symmetrically arranged semi-circular guide plates 45 are slidably connected to the inner side of the lower end of the movable plate 44, and the semi-circular guide plates 45 are fixedly connected to the worktable 1.

[0030] Specifically, the semi-circular guide plate 45 can smoothly guide the moving plate 44.

[0031] In this embodiment, the outer surface of the rotating rod 43 is disposed through one side of the workbench 1, and the output end of the stepper motor 42 is rotatably connected to the workbench 1 through a bearing.

[0032] Specifically, ensure that the output of stepper motor 42 does not interfere with the worktable 1.

[0033] In this embodiment, the inner end of the clamping plate 463 is rounded, and the width of the clamping plate 463 is less than the distance between the end faces of the two arc-shaped plates 462.

[0034] Specifically, it ensures that the clamping plate 463 does not cause hard contact at the end faces when clamping the insulator.

[0035] In this embodiment, two symmetrically arranged limiting plates 468 are fixedly connected to one end of the bidirectional rack 466 near the electric push rod 467.

[0036] Specifically, the displacement of the bidirectional rack 466 can be limited by the limiting plate 468.

[0037] Working principle: When using the device, two insulators of the same type can be placed into two corresponding bidirectional clamping concentric assemblies 46. Then, the electric push rod 467 is powered by the power supply 2 and the controller 3. The output end of the electric push rod 467 drives the bidirectional rack 466 to move closer to the electric push rod 467. The bidirectional rack 466 then drives two gears 465 to move in opposite directions. The upper gear 465 drives the corresponding rotating shaft 464 to rotate counterclockwise, and the lower gear 465 drives the corresponding rotating shaft 464 to rotate clockwise. Through the two gears 465, the clamping plates 463 can be indirectly driven to move closer together. Two clamping plates 463 perform synchronous clamping actions on insulators of different sizes, ensuring concentricity after clamping. Next, power is supplied to stepper motor 42 through power supply 2 and controller 3. At this time, the output end of stepper motor 42 drives rotating rod 43 to rotate, which in turn drives two symmetrically arranged moving plates 44 to move closer to each other. Moving plates 44 slide with semi-circular guide plate 45. When the end faces of multiple sets of corresponding insulators abut, the power supply to stepper motor 42 can be stopped. This utility model realizes the clamping of insulators of different sizes and the ability to keep the two clamped insulators concentric, improving the efficiency of subsequent insulator processing.
