Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a device for detecting the swing angle of a drive shaft assembly. Background Technology

[0002] The driveshaft assembly swing angle detection device is mainly used for quality control of driveshaft assemblies, ensuring that products meet production standards and reducing the defect rate; evaluating its performance under different operating conditions, such as changes in swing angle under different torques, speeds, and loads, to determine reliability and stability; diagnosing faults in use, such as component wear, deformation, loosening, or damage; assisting in new product development, providing data for design optimization and improvement, and enhancing performance and lifespan; and ensuring operational safety by keeping the swing angle within a safe range, preventing mechanical failures, accidents, or damage to related components. In practical applications, the driveshaft assembly swing angle detection device typically requires the following technologies:

[0003] 1. Fixing and support structure: including mounting brackets, bases, etc., used to securely install sensors and fix drive shafts to ensure the stability of the device during the detection process;

[0004] 2. Control system: Used to control the start-up, stop, parameter setting, and other operations of the detection device;

[0005] 3. Signal processing module: Performs filtering, amplification, and correction on the acquired data to improve the accuracy and reliability of the data.

[0006] For example, a Chinese patent discloses a torque transmission shaft torsion angle measuring mechanism (publication number: CN209945234U). This mechanism uses the connection position of the second positioning shaft on the fixed plate as a reference position, which corresponds to the connection position of the first positioning shaft on the measuring plate. The transmission shaft is manually rotated until the right end of the mark aligns with the reference position. The locking screw is then manually rotated to compress the second connecting sleeve, ensuring that the second connecting sleeve and the fixed plate cannot rotate relative to each other. Moving the pointer along the annular hole on the measuring plate until the left end of the mark aligns with the pointer, the alignment angle of the pointer on the measuring plate is the torsion angle of the transmission shaft. This device is easy to operate, provides intuitive observation, and has high accuracy, greatly improving maintenance efficiency.

[0007] However, during the implementation of the above technical solution, at least the following technical problems were found: As mentioned above, the device has a low degree of automation and requires manual operation for measurement and fixation, which makes it difficult to guarantee work efficiency and detection accuracy. In addition, the device is highly complex to operate, requiring operators to manually rotate the drive shaft, align the marks, and rotate the locking screws, which is relatively cumbersome and prone to human error, resulting in differences in subsequent test data. Utility Model Content

This solves the problems of low automation, the need for manual operation for measurement and fixation, difficulty in ensuring work efficiency and detection accuracy, and high operational complexity, requiring operators to manually rotate the drive shaft, align marks, and tighten screws, which are relatively cumbersome and prone to human error, leading to discrepancies in subsequent test data.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A drive shaft assembly swing angle detection device includes a base, and a detection mechanism is provided on the top of the base.

[0018] (III) Beneficial Effects

[0019] 1. The motor drives the first gear to rotate counterclockwise, which in turn drives the second gear to rotate clockwise. The second gear drives the transmission assembly to rotate clockwise, which in turn drives the rotating column to rotate clockwise. The rotating column then drives the swing rod to rotate clockwise in a circular motion. The ball bearings slide on the top of the base to reduce friction. The swing rod drives the receiving block to rotate clockwise in a circular motion, which in turn drives the locking plate to rotate clockwise in a circular motion. The locking plate then drives the two ends of the transmission rod shaft to perform detection. When the capacitive angle sensor has not moved for a long time, the sensor receiver will record the angle of deflection of the capacitive angle sensor. The sensor receiver will then transmit the signal to the signal transmitter, which will then transmit the signal to the signal receiver. The signal receiver will record the data and control the motor to rotate clockwise, measuring the backward swing angle of the transmission shaft, thereby facilitating the detection of the swing angle of the transmission shaft assembly.

[0020] 2. Place the drive shaft assembly inside the concave block, then rotate the first threaded rod counterclockwise. The first threaded rod drives the sliding plate to move from back to front. The sliding plate locks the drive shaft. Then align the two ends of the drive shaft with the locking plate and rotate the limiting plate counterclockwise. The limiting plate drives the locking plate to move from both sides to the middle until the locking plate abuts against the two ends of the drive shaft assembly, thereby achieving the function of quickly fixing the drive shaft assembly.

Detailed Implementation

[0027] This application provides a drive shaft assembly swing angle detection device, effectively solving the problems of the low automation level of the aforementioned devices, which require manual operation for measurement and fixation, making it difficult to guarantee work efficiency and detection accuracy. Furthermore, the aforementioned devices are highly complex to operate, requiring manual rotation of the drive shaft, alignment of marks, and tightening of locking screws, which are relatively cumbersome and prone to human error, leading to discrepancies in subsequent detection data. The motor drives the first gear to rotate counterclockwise, which in turn drives the second gear to rotate clockwise. The second gear drives the transmission assembly to rotate clockwise, which in turn drives the rotating column to rotate clockwise. The rotating column then drives the swing rod to rotate clockwise in a circular motion. The ball bearings slide on the top of the base, reducing friction. The swing rod drives the receiving block to rotate clockwise in a circular motion, which in turn drives the locking plate to rotate clockwise in a circular motion, thus locking the connection. The plate drives the transmission shaft at both ends for detection. When the capacitive angle sensor has not moved for a long time, the sensor receiver will record the angle of deflection of the capacitive angle sensor. The sensor receiver transmits the signal to the signal transmitter, and the signal transmitter transmits the signal to the signal receiver. The signal receiver records the data and controls the motor to rotate clockwise to measure the backward swing angle of the transmission shaft, thereby facilitating the detection of the swing angle of the transmission shaft assembly. The transmission shaft assembly is placed inside the concave block, and then the first threaded rod is rotated counterclockwise. The first threaded rod drives the sliding plate to move from back to front. The sliding plate locks the transmission shaft. Then, the two ends of the transmission shaft are aligned with the locking plate, and the limiting plate is rotated counterclockwise. The limiting plate drives the locking plate to move from both sides to the middle until the locking plate abuts against the two ends of the transmission shaft assembly, thereby achieving the function of quickly fixing the transmission shaft assembly.

When the capacitive angle sensor 24 has not moved for a long time, the sensor receiver 25 will record the angle of deflection of the capacitive angle sensor 24. The sensor receiver 25 will transmit the signal to the signal transmitter 26, and the signal transmitter 26 will transmit the signal to the signal receiver 27. The signal receiver 27 will record the data and control the motor 12 to rotate clockwise, measuring the backward swing angle of the transmission shaft, thereby achieving the function of conveniently detecting the swing angle of the transmission shaft assembly.

A second threaded rod 22 is rotatably installed inside the receiving block 19. A limit plate 23 is fixedly installed on the side wall of the second threaded rod 22. A signal receiver 27 is fixedly installed on the side wall of the motor 12. A concave block 28 is fixedly installed on the top of the base 11.

The limit plate 23 is rotated counterclockwise. The limit plate 23 drives the locking plate 21 to move from both sides to the middle until the locking plate 21 abuts against the two ends of the drive shaft assembly, thereby achieving the function of quickly fixing the drive shaft assembly.

[0032] To address the problems existing in the prior art, this utility model provides a drive shaft assembly swing angle detection device. Motor 12 drives first gear 13 to rotate counterclockwise, first gear 13 drives second gear 14 to rotate clockwise, second gear 14 drives transmission assembly 15 to rotate clockwise, transmission assembly 15 drives rotating column 16 to rotate clockwise, rotating column 16 drives swing rod 17 to rotate clockwise in a circular motion, ball bearing 18 slides on top of base 11 to reduce friction, swing rod 17 drives receiving block 19 to rotate clockwise in a circular motion, receiving block 19 drives locking plate 21 to rotate clockwise in a circular motion, locking plate 21 drives both ends of the transmission shaft to perform detection.

The signal receiver 27 records the data and controls the motor 12 to rotate clockwise.

The drive shaft assembly is placed inside the concave block 28, and the first threaded rod is rotated counterclockwise. The first threaded rod drives the sliding plate 29 to move from back to front.

The limiting plate 23 drives the locking plate 21 to move from both sides to the middle until the locking plate 21 abuts against the two ends of the drive shaft assembly, thereby achieving the function of quickly fixing the drive shaft assembly.

[0033] Working principle:

[0034] First, place the drive shaft assembly inside the concave block 28, then rotate the first threaded rod counterclockwise. The first threaded rod drives the sliding plate 29 to move from back to front, and the sliding plate 29 locks the drive shaft. Then, align the two ends of the drive shaft with the locking plate 21, and rotate the limiting plate 23 counterclockwise. The limiting plate 23 drives the locking plate 21 to move from both sides to the middle until the locking plate 21 abuts against the two ends of the drive shaft assembly, thereby achieving the function of quickly fixing the drive shaft assembly.

[0035] The second step involves starting motor 12. Motor 12 drives the first gear 13 to rotate counterclockwise, which in turn drives the second gear 14 to rotate clockwise. The second gear 14 then drives the transmission assembly 15 to rotate clockwise, which in turn drives the rotating column 16 to rotate clockwise. The rotating column 16 then drives the swing rod 17 to rotate clockwise in a circular motion. The ball bearing 18 slides on the top of the base 11 to reduce friction. The swing rod 17 drives the receiving block 19 to rotate clockwise in a circular motion, which in turn drives the locking plate 21 to rotate clockwise in a circular motion. The locking plate 21 drives the two ends of the transmission shaft to perform detection. When the capacitive angle sensor 24 has not moved for a long time, the sensor receiver 25 records the angle of deflection of the capacitive angle sensor 24. The sensor receiver 25 transmits the signal to the signal transmitter 26, which then transmits the signal to the signal receiver 27. The signal receiver 27 records the data and controls motor 12 to rotate clockwise, measuring the backward swing angle of the transmission shaft, thereby facilitating the detection of the swing angle of the transmission shaft assembly.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
