Description

Technical Field

[0001] This utility model relates to the field of power testing technology, and in particular to an adjustment frame for testing power conductor fittings. Background Technology

[0002] Power conductor fittings are crucial components in power systems used to connect and secure conductors, and their quality directly impacts the safety and reliability of the power grid. To ensure fitting performance, testing equipment typically requires an adjustment frame to support and position the testing tools. In existing technologies, adjustment frames usually employ lifting or sliding mechanisms for unidirectional adjustment, such as vertical lifting via threaded rods or horizontal movement via slide rails and lead screws. Some adjustment frames are also equipped with motor drives to improve operational efficiency. These devices are widely used in power equipment manufacturing and maintenance scenarios and can meet basic testing needs. However, existing adjustment frame designs are mostly single-function modules with relatively simple structures, suitable for routine testing tasks. Their flexibility and efficiency still need improvement when frequent adjustments to the testing angle and position are required under complex operating conditions.

[0003] Existing adjustment frames have several drawbacks. First, most adjustment frames only support single-direction adjustment, such as only lifting or horizontal movement, lacking multi-degree-of-freedom adjustment capabilities. This makes them unsuitable for the diverse angle and position requirements in hardware inspection, resulting in low inspection efficiency. Second, existing adjustment frames lack stability, especially under high load or vibration environments, where rotating connecting parts or sliding mechanisms are prone to loosening, affecting inspection accuracy. Furthermore, some adjustment frames have poor versatility; the design of the mounting base or fixture platform is difficult to adapt to various inspection tools, limiting their application range. Although some existing devices use motor drives, the control precision and automation level are limited, making it difficult to meet the requirements of high-precision inspection. These shortcomings render existing adjustment frames insufficiently practical and reliable in complex inspection scenarios, necessitating urgent improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an adjustment frame for testing power conductor fittings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjusting frame for testing power conductor fittings includes a lifting mechanism arranged vertically for vertical adjustment. It comprises a threaded rod, a threaded sleeve, a T-shaped rod, and a fixing plate. The threaded rod is externally threaded to the threaded sleeve, and the top of the threaded sleeve is rotatably connected to the T-shaped rod. The top of the T-shaped rod is fixed to the fixing plate. An adjusting box, horizontally positioned at the top of the lifting mechanism for lateral support, includes a long, narrow box body with an open top. Slots are formed on two opposite inner walls of the box body, and a partition is fixed in the middle of the box body. Openings are also provided on both sides of the box body. An opening is provided, within which a bearing is fixed; a lead screw is used for transmission, with one end rotatably mounted on one side of a partition, and the other end sleeved on the inner ring of the bearing and extending to the outside of the housing; a fixture mounting base is connected to the lead screw and achieves horizontal displacement through the drive of the lead screw, including a slider, a nut, a ball seat, a ball head, and a mounting plate, with the nut fixed to the bottom of the slider, the ball seat fixed to the top of the slider, the ball head rotatably mounted inside the ball seat, and the mounting plate fixed to the top of the ball head; a stepper motor is used to drive the lead screw to rotate, fixed to one side of the housing, and the output end of the stepper motor is fixedly connected to one end of the lead screw.

[0007] Preferably, the lifting mechanism further includes a mounting base fixed to the bottom of the threaded rod.

[0008] Preferably, the lifting mechanism further includes a base plate fixed to the bottom end of the threaded rod and an anti-slip pad fixed to the bottom of the base plate.

[0009] Preferably, the inner wall of the threaded sleeve is provided with a first limiting ring, and the top end of the threaded sleeve is provided with a second limiting ring. The cavity structure between the first limiting ring and the second limiting ring matches the head of the T-shaped round rod.

[0010] Preferably, the fixture mounting base further includes bosses disposed on both sides of the slider, the bosses matching the slide groove and being able to slide inside the slide groove.

[0011] Preferably, the fixture mounting base further includes a plurality of mounting holes provided on the mounting plate and a fastening knob threaded onto the outer wall of the ball seat.

[0012] This utility model has the following beneficial effects:

[0013] 1. This adjustment frame, through its lifting mechanism, screw drive, and ball joint structure on the fixture mounting base, achieves comprehensive adjustment in the vertical, horizontal, and multi-angle directions, flexibly adapting to diverse position and angle requirements in the inspection of power conductor fittings. The threaded rod and threaded sleeve work together to achieve precise lifting, while the screw-driven slider ensures smooth horizontal movement. The ball joint and ball head design allow the mounting plate to freely adjust its angle, significantly improving the positioning accuracy of the inspection tool. Compared to traditional single-direction adjustment frames, this device can quickly adapt to complex working conditions, reduce manual adjustment time, and improve inspection efficiency. It is particularly suitable for high-precision inspection tasks in fitting manufacturing and maintenance, providing efficient and flexible support for quality control in power systems.

[0014] 2. This adjustment frame significantly improves the stability of the device and ensures high-precision testing through structural optimizations such as limiting rings, bosses, and fastening knobs. The first and second limiting rings inside the threaded sleeve match the T-shaped round rod, restricting its axial movement and enhancing the reliability of the lifting mechanism; the bosses on both sides of the slider cooperate with the slide grooves to ensure the guidance and stability of horizontal movement; the fastening knob locks the ball head position to prevent angular deviation. These designs effectively reduce the risk of component loosening or displacement under high load or vibration environments, ensuring stable positioning of the testing tool. Compared to the shortcomings of existing adjustment frames that are prone to loosening, this device can maintain high precision under complex working conditions, extending the service life of the equipment, and is suitable for the harsh testing scenarios of power fittings.

[0015] 3. This adjustment frame adopts a modular design, including an independent lifting mechanism, adjustment box, and fixture mounting base. Each component has a clearly defined function and is easy to assemble and disassemble, improving versatility and maintenance convenience. Multiple mounting holes on the mounting plate support the fixing of different testing tools, enhancing the device's compatibility.

The base plate and anti-slip pads further enhance the device's adaptability to various working environments. Compared to the fixed structure of traditional adjustment frames, this device allows for quick replacement or repair of components, reducing maintenance costs. It also adapts to various hardware testing needs, providing a flexible and economical solution for power equipment manufacturing, quality inspection, and maintenance, significantly enhancing the equipment's market competitiveness.
