[0025] In this embodiment, the first motor 1 drives the precision transmission assembly to rotate through the driving shaft thereof, and the precision transmission assembly accurately transmits the rotary motion of the motor to the first measuring assembly. The precision transmission assembly is designed to ensure high precision in the transmission process, so as to meet the strict requirements on precision in the measuring process. In particular, when the swing arm reciprocates, the transmission assembly can effectively reduce the system error and ensure the measuring precision.

[0026] Specifically, the precision transmission assembly comprises a first main shaft 2 connected to the first motor 1, and the first main shaft 2 is rotatably arranged in the shell body 13.

[0027] In this embodiment, the driving force of the first motor 1 is directly transmitted to each component in the precision transmission assembly through the first main shaft 2. The rotary motion of the first main shaft 2 accurately controls the motion of the entire transmission system, so that the measuring device can perform high-precision measuring operation. This design ensures that the main shaft maintains good balance and stability during rotation, thereby reducing the measuring error caused by eccentricity of the main shaft.

[0028] Please refer to Figure 1 and Figure 2The first main shaft 2 is provided with a first gear 3, and the first gear 3 is gear-connected with a second gear 4.

[0029] In this embodiment, the first main shaft 2 is engaged with the second gear 4 through the first gear 3 mounted thereon, and the gear transmission ensures efficient power transmission and accurate control. Through this gear transmission structure, precise adjustment of the transmission ratio can be achieved in a limited space, thereby achieving precise control of the movement of the measuring device.

[0030] Specifically, the second gear 4 is provided with a first transmission shaft 5, and one side of the first transmission shaft 5 is connected with a first worm 6.

[0031] In this embodiment, the rotation of the second gear 4 is transmitted to the first worm 6 through the first transmission shaft 5. The first worm 6 further converts the rotary motion into the input of the worm gear transmission system. This worm transmission mechanism not only provides high torque output, but also accurately controls the angular position of the output shaft, thereby improving the operation accuracy of the entire measuring device.

[0032] Specifically, the first worm 6 is gear-connected with a first worm gear 7.

[0033] In this embodiment, the first worm 6 is engaged with the first worm gear 7, and through the transmission relationship between the worm and the worm gear, the speed is further reduced and the torque output is increased. This design makes the rotary motion of the worm gear more stable, thereby ensuring that the movement of the swing arm can be accurately controlled during precise measurement, reducing measurement errors.

[0034] Please refer to Figure 1 and Figure 2 The first worm gear 7 is provided with a second transmission shaft 8.

[0035] In this embodiment, the rotary motion of the first worm gear 7 is transmitted to the second transmission shaft 8, so that the motion of the worm gear can be further transmitted to the subsequent motion mechanism through the transmission shaft. Through this design, the precise motion of the worm gear can be directly transmitted to the final measuring component, ensuring the overall accuracy of the system.

[0036] Specifically, the second transmission shaft 8 is provided at one end with a first rotating rod 9.

The installation of the first rotating rod 9 makes the rotary motion of the transmission shaft can be converted into the rotation of the rotating rod, thereby further driving the precise positioning of the swing arm. This design ensures smooth switching of the measuring device between different positions, improves the response speed and control accuracy of the system.

Through the combination of the two rotating rods, the precise adjustment of the probe position can be achieved in a limited space to adapt to different measurement requirements. The fixed seat 11 ensures the stability of the probe 12, so that it can maintain an accurate position during the measurement process, ensuring the accuracy of the measurement results.

[0040] Working principle:

[0041] The design of this numerical control swing arm type measuring device mainly revolves around high-precision mechanical transmission and the realization of measurement functions. Its core working principle can be divided into several key steps:

[0042] Power transmission and primary transmission:

[0043] The device provides initial power through the first motor 1. The rotational motion of the motor is accurately transmitted to the first main shaft 2 through a precision transmission assembly. The first main shaft 2 is responsible for efficiently and accurately transmitting the power of the motor to the next level of transmission assembly.

[0044] Gear transmission and motion conversion:

[0045] The first main shaft 2 drives the first gear 3 to rotate, and the first gear 3 engages with the second gear 4 through a gear transmission mechanism to transmit the rotational motion to the second gear 4. This part of the gear transmission not only ensures the accuracy of the transmission, but also changes the direction of motion and adjusts the transmission ratio, laying a foundation for subsequent precise measurement.

[0046] Worm and worm gear speed reduction:

[0047] The rotational motion of the second gear 4 is transmitted to the first worm 6 through the first transmission shaft 5. The engagement of the worm and the worm gear further reduces the transmission speed and increases the output torque, so that the system can still maintain high precision control when handling large swing arms. The first worm gear 7 transmits the rotational motion of the worm to the second transmission shaft 8.

[0048] Rotating rod transmission and position control:

[0049] The rotational motion of the second transmission shaft 8 is transmitted through the first rotating rod 9. The first rotating rod 9 and the connected second rotating rod 10 form a two-stage lever system, which enables the device to adjust the position of the measurement probe in a larger range, thereby adapting to different measurement tasks. The combination of the fixed seat 11 and the first probe 12 allows the measuring device to accurately detect at different positions.

[0050] Precise measurement:

[0051] Finally, through the precise mechanical transmission system, the first probe 12 can swing to the target position under control to make precise measurement on the surface of the workpiece. Every tiny change of the probe position is precisely controlled by the transmission system, ensuring the reliability and accuracy of the measurement results.

[0052] Overall, the numerical control swing arm type measuring device realizes precise control of the position of the measuring probe through the precise cooperation of the multi-stage transmission mechanism, can maintain high-precision measurement effect in the complex numerical control machining process, and effectively meets the high requirement of industrial measurement task. Figure 3 As shown, the first probe 12 moves at a speed V under the driving of the first motor 1.
