Description

TECHNICAL FIELD

[0001] The utility model relates to power equipment technical field, concretely relates to a preassembly mechanism for insulator product crimping. BACKGROUND

[0002] Insulator is an indispensable key component in high-voltage overhead transmission line and substation, and the reliability of its performance is directly related to the safe and stable operation of the power grid. The typical composite insulator structure is composed of three parts: the internal glass fiber reinforced epoxy resin core rod, which provides the insulator with solid mechanical strength; the external silicone rubber umbrella skirt, which endows it with excellent insulation performance and hydrophobicity; and the metal connecting hardware (such as bowl head hanging plate, ball head hanging ring, etc.) at both ends, which is used to firmly connect the insulator to the wire or tower.

[0003] In the production process of some existing composite insulators, the connection between the core rod and the hardware is a crucial link, and the two are usually connected by a high-strength mechanical connection through a crimping process. Before formal crimping, the corresponding pre-assembly must be completed. Of course, the pre-assembly operation of each insulator product may be different. For example: sometimes it is necessary to insert the corresponding hardware (such as a steel sleeve) into the inner hole of the two end portions of the core rod, and ensure that the position angle of the two hardware is specific, or accurately sleeve the corresponding hardware on the specific position of the middle portion of the core rod, etc. After the pre-assembly is completed, the pre-assembled product is placed in the crimping machine for final fixed crimping forming. The accuracy of pre-assembly has a direct impact on the subsequent crimping process. If the core rod and the hardware are not accurately aligned during pre-assembly, it may cause the crimping quality to be unqualified due to skewing, misplacement, etc. Therefore, pre-assembly not only lays the foundation for the subsequent crimping process, but also is a key link to ensure the overall performance reliability of the insulator product.

[0004] At present, the pre-assembly of some insulators is completely completed by manual work, which is time-consuming and laborious. The present application aims to provide a pre-assembly mechanism for insulator products, which can be used to assist in accurately sleeving the hardware of the corresponding insulator product on the core rod to improve the efficiency of pre-assembly.

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to specific embodiments. Methods or functional components not specifically described in the embodiments are all prior art. Unless otherwise defined, all technical terms and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. Example

[0025] like Figures 1-5 As shown, this embodiment is a pre-assembly mechanism for crimping insulator products, including a workbench 1. The workbench 1 is provided with a mandrel 5 sorting mechanism 2. A pushing mechanism 3 is provided on one side of the mandrel 5 sorting mechanism 2, and a fitting fixing mechanism 4 is provided on the other side of the mandrel 5 sorting mechanism 2. The mandrel 5 sorting mechanism 2 is used to arrange the mandrels 5 in a row. The fitting fixing mechanism 4 is used to fix the fittings 6 to be installed. The pushing mechanism 3 is used to push the arranged mandrels 5 out of the mandrel 5 sorting mechanism 2 and insert them into the corresponding fittings 6.

[0026] In this embodiment, the mandrel 5 sorting mechanism 2 includes a feeding hopper 21, which is equipped with a guiding mechanism. The guiding mechanism includes a rotating shaft 23, a turntable 24, and a guide rod 22. The rotating shaft 23 is connected to a motor and rotates under the drive of the motor. A feeding channel 25 is provided at the bottom of the feeding hopper 21, and the guide rod 22 is used to guide the mandrel 5 to slide into the feeding channel 25. The width of the feeding channel 25 matches the diameter of the mandrel 5 to be processed, allowing the mandrel 5 to move flexibly in the feeding channel 25. A storage box 26 is provided at the outlet of the feeding channel 25. The width of the storage box 26 matches the diameter of the mandrel 5, allowing the mandrel 5 to be stacked vertically in a single row in the storage box 26. Pushing holes 27 are provided on both sides of the storage box 26, and the size and position of the pushing holes 27 are adapted to the mandrel 5 at the bottom of the storage box 26.

[0027] In this embodiment, the pushing mechanism 3 includes a push rod. When the push rod is working, the movable end of the push rod enters through the pushing through hole 27 on one side of the storage box 26 and pushes against the lowest core rod 5 in the storage box 26. Then it passes through the pushing through hole 27 on the other side of the storage box 26, so that the pushed core rod 5 is completely removed from the storage box 26.

[0028] In this embodiment, the hardware fixing mechanism 4 includes a sliding seat 41 and a clamp 42. A slide groove 7 is provided on the worktable 1. The sliding seat 41 is limited to moving in the slide groove 7. The clamp 42 is provided on the sliding seat 41 and is used to stably clamp the hardware 6 to ensure that the through hole of the hardware 6 corresponds to the push through hole 27.

[0029] In this embodiment, a guide tube 8 is also provided at the push-through hole 27 adjacent to the hardware fixing mechanism 4. The diameter of the guide tube 8 is adapted to the mandrel 5. One end of the guide tube 8 is connected to the push-through hole 27, and the other end corresponds to the through hole of the hardware 6. The length of the guide tube 8 can be customized according to actual needs, or a telescopic structure can be directly adopted. The function of the guide tube 8 is to ensure that the mandrel 5 can be accurately inserted into the through hole of the hardware 6 when the push rod is working.

[0030] In this embodiment, the clamp 42 and the sliding seat 41 are detachably connected by bolts. The specific structure of the clamp 42 can be designed according to the hardware 6. A limiting mechanism is provided on the sliding seat 41 to fix the sliding seat 41 in the slide groove 7. The limiting mechanism can be a bolt or a screw.

[0031] The pre-assembly mechanism in this embodiment is suitable for insulator products that require fittings 6 to be fitted onto the middle of core rods 5. In use, multiple core rods 5 can be placed into the core rod organizing mechanism 2, which automatically arranges them. Then, the relative positions of the fitting fixing mechanism 4 and the core rod organizing mechanism 2 are adjusted, and the fittings 6 are fixed onto the fitting fixing mechanism 4. The pushing mechanism 3 is then activated, its push rod extending into the storage box 26 and pushing out the bottommost core rod 5. The pushed-out core rod 5, under the action of the guide tube 8, can be accurately inserted into the corresponding through hole of the fitting 6. After completion, the fixing mechanism 4 is released (along the extension direction of the guide tube 8), the pre-assembled product is removed, and a new fitting 6 is placed in, repeating this process. Workers only need to focus on clamping and unloading the fittings 6, greatly reducing labor intensity and improving efficiency.

[0032] The above are only some embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various combinations and modifications of the aforementioned technical features. Any improvements, modifications, equivalent substitutions, or applications of the structure or method of the present utility model to other fields to achieve the same effect without departing from the spirit and scope of the present utility model shall fall within the protection scope of the present utility model.
