AI Technical Summary
Existing multi-splitter spacer assembly and positioning devices are unable to fully conform to the irregular outer contour of the spacer, resulting in uneven clamping force distribution, causing shaking or displacement, and affecting assembly accuracy.
A multi-splitter spacer assembly positioning fixture, including a fixing mechanism and a lifting mechanism, is adopted. The spacer is stably fixed by a combination design of an expansion ring and a compression block. The height of the fixture can be adjusted by a motor drive to adapt to different operating requirements.
This improves the stability and precision of the assembly process, ensuring that the spacer bars do not shake or shift during assembly, thus enhancing operational convenience and assembly efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of power technology, specifically to a multi-split spacer assembly and positioning fixture. Background Technology
[0002] The nano-anti-aging multi-split spacer bar for ultra-high voltage transmission lines is the most advanced new generation of forged spacer bars in China. This product meets the needs of ultra-high voltage transmission lines in China. Different specifications such as two, three, four, six, and eight-split types can be selected according to the needs of ultra-high voltage transmission lines. It is mainly composed of components such as connecting plate body, wire clamp, ball joint, and gravity balancer, presenting a radial layout.
[0003] In power transmission lines, multi-split conductors are composed of multiple conductors arranged in parallel. Spacers are used to fix the relative positions of the split conductors and prevent the conductors from whipping or galloping against each other. Spacers need to be fixed when assembling multi-split spacers.
[0004] Existing multi-split spacer assembly positioning devices mostly achieve positioning and fixation by clamping the outside of the multi-split spacer. Since some spacers have irregular protrusions or grooves on the outside, the existing clamping devices are difficult to completely fit their external contours, which can easily lead to uneven distribution of clamping force. This can cause the spacers to shake or shift during assembly, thus affecting the assembly accuracy. Therefore, a multi-split spacer assembly positioning fixture is proposed. Utility Model Content

[0017] (III) Beneficial Effects
[0018] This invention provides a positioning fixture for assembling multi-splitter spacers. It has the following advantages:
[0019] (I) This multi-split spacer assembly positioning fixture and fixing mechanism, by manually rotating the first threaded rod, causes the control block to move within the fixed frame and drive multiple expansion rings to open outward via the connecting plate, making them in close contact with the inner side of the multi-split spacer, thus achieving a firm fixation and preventing shaking or displacement during assembly; enhancing the fixing stability; the rotating rod of the rotating part is connected to the fixed frame, and the extrusion ring on the rotating rod cooperates with the extrusion screw and extrusion block on the fixed plate. During assembly, the fixed frame can be rotated first for convenient multi-angle operation. After rotation, the extrusion block and the inner side of the extrusion ring are pressed to reliably fix the fixed frame, preventing arbitrary rotation and ensuring the stability and accuracy of the assembly process.
[0020] (II) The multi-split spacer assembly positioning fixture includes a lifting mechanism that drives the second threaded rod to rotate via a motor, causing the threaded lifting block to move up and down along the rod. This, in turn, allows the connecting block and fixing mechanism to move up and down via a control frame. The fixture height can be flexibly adjusted to suit the user's height, meet the actual needs of the operator, and improve operational convenience and assembly efficiency. After adjusting the height, the reinforcing screw on the reinforcing frame on the outer wall of the lifting block is tightened to press the inner wall of the pressing groove on the outer wall of the fixing sleeve, reliably fixing the position of the connecting block and providing stable support for the assembly of the multi-split spacer.
