Description

Technical Field

[0001] This utility model relates to the field of fixed tooling technology, specifically a compass calibration tooling fixture. Background Technology

[0002] An electronic compass, also known as a digital compass or digital compass, is an electronic navigation instrument that uses modern electronic manufacturing technology to determine direction through the Earth's magnetic field. Compared to traditional pointer compasses, electronic compasses offer advantages such as lightweight design, high accuracy, small size, portability, and low power consumption. They are widely used in numerous fields, including automotive manufacturing, robotics, aerospace, and maritime applications, and are also extensively used in helicopters. The compass is also a crucial component during helicopter maintenance. Since the compass is fixed to the helicopter and is typically not disassembled during maintenance, the testing instrument must be placed on the helicopter's collector for inspection. Because the testing position cannot be changed, the testing instrument also requires fixtures for fixation during compass testing. Existing compass testing fixtures are inconvenient to carry and operate. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a compass calibration fixture in response to the above-mentioned shortcomings.

[0004] To solve the above technical problems, the present invention adopts the following technical solution:

[0005] A compass calibration fixture includes a cylindrical base, support beams, an operating platform, and fastening bolts. The operating platform, which is circular and located directly above the center of the cylindrical base, is positioned above the cylindrical base. Multiple support beams are arranged between the operating platform and the cylindrical base. The operating platform is used to mount an external compass testing device. Multiple fastening bolts, all horizontally penetrating and extending to the inner side of the cylindrical base, are evenly threaded onto the cylindrical base. The cylindrical base is hollow and is used to fit onto a helicopter collector dust cover. The fastening bolts are used to fix the cylindrical base to the outside of the collector dust cover. After the cylindrical base is fixed to the outside of the collector dust cover, the operating platform is in a horizontal position.

[0006] Furthermore, a washer is provided at one end of the fastening bolt located inside the cylindrical base.

[0007] Furthermore, both the cylindrical base and the support beam are made of copper.

[0008] Furthermore, the operating platform coincides with the axis of the cylindrical base.

[0009] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0010] This invention features a lightweight design with a copper cylindrical base and supporting beams, making it easy to transport to helicopter maintenance sites. The cylindrical base allows for convenient mounting onto the helicopter collector dust cover, quickly secured with bolts without complex installation. Multiple evenly distributed bolts ensure stable attachment to the dust cover, accommodating dust covers of different sizes and shapes, thus improving the tooling's versatility and adaptability. The bolt design also ensures a quick and reliable fixing process. Washers on the bolts prevent damage to the dust cover surface.

[0011] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0018] like Figure 1-2As shown, a compass calibration fixture includes a cylindrical base 1, support beams 2, an operating platform 3, and fastening bolts 4. The operating platform 3 is disposed above the cylindrical base 1. The operating platform 3 is circular and located directly above the center of the cylindrical base 1. Multiple support beams 2 are disposed between the operating platform 3 and the cylindrical base 1. The operating platform 3 is used to install external compass testing equipment. Multiple fastening bolts 4 are evenly threaded on the cylindrical base 1, all horizontally penetrating and extending to the inner side of the cylindrical base 1. The cylindrical base 1 is hollow and cylindrical. The cylindrical base 1 is used to fit onto the dust cover of a helicopter collector. The fastening bolts 4 are used to fix the cylindrical base 1 to the outside of the dust cover of the collector. After the cylindrical base 1 is fixed to the outside of the dust cover of the collector, the operating platform 3 is in a horizontal state.

[0019] In one embodiment, a washer 5 is provided at one end of the fastening bolt 4 located inside the cylindrical base 1.
