[0002] A servo is a position (angle) servo drive. Its primary function is to convert an input electrical signal into a corresponding mechanical angle position, thereby driving the controlled object to rotate at a preset angle and maintaining this control state. Servos are widely used in industry, military, aerospace, shipbuilding, robotics, and other fields.

[0003] Electromagnetic compatibility testing is a comprehensive assessment of the electromagnetic interference and anti-interference capabilities of electronic products. It ensures that electronic equipment can operate normally in complex electromagnetic environments without interfering with other equipment. This test is one of the important indicators of servo product quality and is crucial for ensuring the stability and reliability of electronic equipment.

[0004] However, the electromagnetic compatibility test fixtures for steering gears in the prior art generally have the following defects, including but not limited to:

[0005] 1. The measurement position of the electromagnetic compatibility strength is fixed. That is to say, the existing electromagnetic compatibility test tooling for servos cannot measure the electromagnetic compatibility strength at different distances behind the servos. This leads to the limitation of the test range, making it inefficient and unable to meet the electromagnetic compatibility strength test requirements at different distances in different scenarios.

[0006] 2. The isolation medium material needs to be replaced quickly, which hinders the rapid identification of the electromagnetic radiation range of the servo and the best isolation medium material.

[0007] In view of this, it is necessary to improve the above defects.

[0031] Please refer to the instruction manual Figures 1-2 The present invention discloses an electromagnetic compatibility test fixture. In addition to the servo body 1 to be tested, the fixture also includes a fixed cylinder 4, an isolation medium 2, a support component, a detection component, and a movable pushing component. The fixed cylinder 4 is used in conjunction with the servo body 1; the isolation medium 2 is detachably arranged between the fixed cylinder 4 and the servo body 1, and is used to reduce the impact of the electromagnetic compatibility strength of the servo on other electronic equipment when the servo is working; the support component is used to support and fix the position of the fixed cylinder 4; the detection component is arranged inside the fixed cylinder 4 and slides inside the fixed cylinder 4 through the movable pushing component. When in use, the detection component placed in the fixed cylinder 4 is moved and pushed by the movable pushing component, so that the electromagnetic compatibility capability of the servo can be measured at different positions.

[0032] In order to further illustrate the specific working principle of this utility model, please refer to the attached manual.

The moving pushing component includes a slide rod 8, which passes through the small hole on the slide rod limit seat 5 and is fixedly connected to the rear end of the detection probe fixing seat 7. When in use, the operator holds the slide rod 8 and applies force to drive the detection probe fixing seat 7 connected thereto and the detection probe to move inside the fixed cylinder 4, so that the distance between the detection probe and the servo body 1 is constantly changing, thereby realizing the electromagnetic compatibility capability of the servo measured at different distances.

[0034] Each of the above components needs to be supported by supporting components, including a support base 10. Support base 2 12 and support base 1 9 are respectively provided at the front and rear ends of the top of the support base 10. A fixing cylinder 4 is provided above support base 2 12. Support base 2 12 has an arc-shaped recess, on which the fixing cylinder 4 is placed and fixedly connected via a fixing cylinder pressure plate 3. Support base 1 9 has a groove that fits the shape of the slide bar 8 and allows the slide bar 8 to slide thereon. A slide bar pressure block 6 is fixedly connected to the top of support base 1 9, which limits the slide bar 8 to the groove of support base 1 9.

[0035] Finally, a debugging power supply hole 11 is opened at the front end of the fixing tube 4. The fixing tube 4 is provided with a servo debugging line and a power supply line. The servo debugging line and the power supply line pass through the debugging power supply hole 11 and are electrically connected to the servo body 1.
