[0030] refer to Figure 4 and Figure 6A No. 2 connecting frame 43 is welded to the upper surface of the No. 1 worm wheel 32, a No. 2 worm 41 is rotatably mounted in the No. 2 connecting frame 43 through a bearing, and a No. 2 handle 44 is integrally provided at one end of the No. 2 worm 41, and a protective cover 45 is welded to one side of the No. 2 connecting frame 43. An arc plate 47 is fixed to one side of the base 46 through rivets, and a connecting shaft 48 is rotatably mounted on one side of the arc plate 47 through a bearing, and one end of the connecting shaft 48 is fixed to the No. 2 worm wheel 42. The No. 2 worm wheel 42 is semicircular, and the upper surface of the No. 2 worm wheel 42 is fixed to the outer surface of the electric actuator body 1 through a fixing frame, a gyroscope 37 is fixed to the lower surface of the No. 1 worm wheel 32, and an angle sensor 49 is fixed to one side of the axis of the No. 2 worm wheel 42;

[0031] Accuracy requirements: Since the gyroscope 37 needs to accurately record the rotation range of the first worm gear 32, the accuracy of the gyroscope 37 is the primary consideration. If the accuracy is not enough, it will cause a large error in the recorded rotation range. For example, in some high-precision mechanical transmission systems, the angle measurement error is required to be controlled within a very small range, and a gyroscope 37 with an accuracy of 0.01° or even higher may be required. For long-term use, the zero bias stability of the gyroscope 37 also needs to be considered. Zero bias refers to the output signal of the gyroscope 37 when there is no input angular velocity, and its stability directly affects the accuracy of the measurement. Stable zero bias can ensure that during the long-term recording of the worm gear rotation, the measurement result will not be distorted due to the accumulation of its own deviation.

[0032] Range requirements: The range of the gyroscope 37 should be selected according to the maximum rotation range of the No. 1 worm wheel 32. If the range is too small, when the rotation angle of the No. 1 worm wheel 32 exceeds the range that the gyroscope 37 can measure, it cannot be accurately recorded. For example, if the No. 1 worm wheel 32 may rotate between -180° and 180°, then it is necessary to select a gyroscope 37 with a range that at least covers this range. At the same time, it is also necessary to consider the overload conditions that may occur during operation. Even if the rotation range of the worm wheel is within the selected range under normal circumstances, short-term shocks or overloads may occur in some special circumstances such as starting and stopping, so it is best for the gyroscope 37 to have a certain overload protection capability, or the range should have an appropriate margin;

[0033] Response speed requirement: The response speed of the gyroscope 37 must match the rotation speed of the first worm wheel 32. If the response speed is too slow, when the first worm wheel 32 rotates quickly, the gyroscope 37 may not be able to accurately record its angle change in time. For example, in a high-speed rotating mechanical device, the rotation speed of the first worm wheel 32 may be high, requiring the gyroscope 37 to be able to respond quickly to changes in angular velocity. Generally speaking, its bandwidth should be wide enough to ensure that it can track the rotation in real time;

[0034] Reliability and stability requirements: Since it is used to record the rotation range, the gyroscope 37 needs to maintain a reliable and stable working state in the working environment. If there are factors such as vibration, temperature changes, and electromagnetic interference in the working environment, it is necessary to select a gyroscope 37 that can adapt to these conditions. For example, in an industrial environment, there may be a large amount of electromagnetic interference generated by motors and other equipment. In this case, it is necessary to select a gyroscope 37 with strong anti-electromagnetic interference capabilities. In addition, the mechanical structure and electronic components of the gyroscope 37 must have sufficient stability to prevent failures during long-term use. For example, high-quality bearings and packaging materials are used to ensure normal operation under different temperature and humidity conditions;

[0035] Interface and data output requirements: The gyroscope 37 needs to have a suitable interface to connect to the recording device, such as the common SPI, I2C and other digital interfaces, to facilitate data transmission and processing. In addition, the data output format must meet the requirements of the recording system. For example, some systems may require the gyroscope 37 to output the absolute value of the angle, while others may only need the relative change value. The data update frequency is also an aspect that needs to be considered. In order to accurately record the rotation range, the data update frequency must be high enough to capture the detailed changes in the worm gear rotation process. For example, in the case of fast rotation, a higher data update frequency can ensure that no critical angle change information is missed.

[0036] High precision is one of the key requirements of the angle sensor 49. Because the rotation angle of the electric actuator body 1 must be accurately recorded, the accuracy of the angle sensor 49 directly affects the accuracy of the measurement results. For example, in some precision automation equipment or robot joint control, the angle accuracy is required to reach ±0.1° or even higher. If the accuracy is insufficient, it will cause errors in the position control of the electric actuator body 1 and affect the performance of the entire system. At the same time, the resolution of the angle sensor 49 is also very important. Resolution refers to the minimum angle change that the sensor can detect. A higher resolution allows the system to sense the rotation state of the electric actuator body 1 more finely. For example, an angle sensor 49 with a resolution of 0.01° can capture tiny angle adjustments of the electric actuator body 1 more accurately than a sensor with a resolution of 0.1°.

[0037] Range requirements: It is necessary to select an angle sensor 49 with a suitable range according to the maximum possible rotation angle of the electric actuator body 1. If the range is too small, when the rotation angle of the electric actuator body 1 exceeds the range of the angle sensor 49, the measurement data will be inaccurate. For example, if the rotation range of the electric actuator body 1 is -90° to 90°, then an angle sensor 49 with a range covering this range should be selected, and it is best to have a certain margin to cope with possible out-of-range rotation situations, such as when the system fails or is subject to external interference.

[0038] Response speed requirement: The response speed of the angle sensor 49 must match the rotation speed of the second worm gear 42 and the electric actuator body 1. In some fast-moving systems, such as high-speed automated production lines or fast-response robotic systems, the electric actuator body 1 may rotate quickly. If the angle sensor 49 responds too slowly, it will not be able to record the angle change in a timely and accurate manner. The bandwidth of the angle sensor 49 should be wide enough to ensure that it can track the rotation of the electric actuator body 1 in real time and output accurate angle information in a timely manner.

[0039] Installation requirements and adaptability: The angle sensor 49 is installed on the axis of the second worm gear 42, so its external dimensions and installation method need to be compatible with the mechanical structure of the axis of the second worm gear 42. It should be easy to install, and after installation, it will not cause additional obstruction or interference to the rotation of the second worm gear 42 and the electric actuator body 1. For example, the volume of the angle sensor 49 cannot be too large, so as not to affect the layout of other surrounding components; its hole position and size should match the existing structure of the axis, so that it can be installed quickly and conveniently. The output signal type and electrical interface of the angle sensor 49 also need to be compatible with the recording and control system. Common output signals include analog signals (such as voltage signals, current signals) and digital signals (such as digital signals of interfaces such as SPI and I2C). The selected output signal of the angle sensor 49 should be able to be easily received and processed by the system in order to accurately record the rotation angle of the electric actuator body 1;

[0040] Working principle: When using this device, firstly, bolts can be installed through the mounting holes 5 in the fixing base 2 to fix the fixing base 2 to the external equipment to achieve the installation of the electric actuator body 1. When the angle of the electric actuator body 1 needs to be changed, the No. 1 worm 31 in the No. 1 adjusting device 3 can be rotated to drive the No. 1 worm wheel 32 to rotate. After the No. 1 worm wheel 32 rotates, the No. 2 adjusting device 4 and the electric actuator body 1 will be driven to rotate horizontally. In this way, the electric actuator body 1 can achieve 360-degree flexible rotation around the axis of the No. 1 worm wheel 32, so as to achieve the purpose of horizontal adjustment of the electric actuator body 1.

[0041] In addition, the No. 2 worm gear 42 can be driven to rotate by twisting the No. 2 worm 41 in the No. 2 adjusting device 4. When the No. 2 worm gear 42 rotates, it will drive the electric actuator body 1 to rotate about the axis of the No. 2 worm gear 42, so that the electric actuator body 1 can be flipped, thereby achieving the effect of flexibly changing the installation angle of the electric actuator body 1; when the electric actuator body 1 rotates and flips horizontally, the gyroscope 37 and the angle sensor 49 will record the adjustment data of the electric actuator body 1, so as to achieve precise adjustment.

[0042] The horizontal rotation angle and the front, back, left, and right angles can be freely adjusted according to the actual situation on site and the layout of surrounding equipment. It is not limited to fixed installation angles, effectively utilizes space, avoids interference problems, and makes installation more convenient and efficient.
