Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The utility model provides a technical solution: an automobile fastener defect detection device, comprising a workbench 1 and a moving mechanism 2, wherein the moving mechanism 2 is provided on one side of the surface of the workbench 1, and a detection mechanism 3 is provided at one end of the workbench 1;

[0025] The moving mechanism 2 includes a mounting groove 201, a first threaded shaft 202, a bevel gear set 203, a first threaded sleeve 204, a first motor 205, a rotating groove 206, a second threaded shaft 207, a belt 208, a second threaded sleeve 209 and a second motor 210. A mounting groove 201 is provided on one side of the workbench 1. The first threaded shaft 202 is embedded in the interior of the mounting groove 201. One side of the first threaded shaft 202 is fixedly connected to the bevel gear set 203. The surface of the first threaded shaft 202 is threadedly connected to the first threaded sleeve 204. One side of the bevel gear set 203 is connected to the first motor 205. A rotating groove 206 is provided at one end of the first threaded sleeve 204. The second threaded shaft 207 is embedded in the interior of the rotating groove 206. A belt 208 is embedded on one side of the second threaded shaft 207. The surface of the second threaded shaft 207 is threadedly connected to the second threaded sleeve 209. The other side of the belt 208 is embedded with the second motor 210. The arrangement of the shaft 202, the bevel gear set 203, the first threaded sleeve 204, the first motor 205, the rotating groove 206, the second threaded shaft 207, the belt 208, the second threaded sleeve 209 and the second motor 210, when the first motor 205 is started, the first motor 205 drives the bevel gear set 203 to rotate, thereby causing the first threaded shaft 202 to rotate synchronously, so that the rotation of the first threaded shaft 202 can drive the first threaded sleeve 204 to move along the first threaded shaft 202, and thereafter when the second motor 210 is started, the belt 208 will drive the second threaded shaft 207 to rotate, causing the second threaded sleeve 209 to slide along the second threaded shaft 207, thereby achieving further fine movement, and the two groups of the first threaded shaft 202 rotate synchronously, and the precise movement of the moving mechanism 2 is achieved through the cooperation of the bevel gear set 203 and the first motor 205, and the sliding of the second threaded shaft 207 further provides a fine-tuning function to ensure that the detection mechanism 3 can be adjusted as needed.

[0026] Furthermore, two groups of first threaded shafts 202 are provided, and the two groups of first threaded shafts 202 are rotated synchronously through the bevel gear set 203. Through the setting of the first threaded shaft 202, the first threaded shaft 202 is fixed in the mounting groove 201 and is threadedly connected to the first threaded sleeve 204. When the first threaded shaft 202 is rotated, the first threaded sleeve 204 will slide along the axial direction of the first threaded shaft 202, thereby driving the structure connected to it to move laterally. Two groups of first threaded shafts 202 are provided in the mechanism, and synchronous rotation is achieved through the bevel gear set 203. The synchronous movement of the two groups of first threaded shafts 202 can ensure the stability and accuracy of the moving mechanism 2 during the movement process, and avoid offset or jamming due to uneven force on one side.

[0027] Furthermore, the bevel gear set 203 and the first motor 205 are arranged inside the mounting groove 201, and the first threaded sleeve 204 forms a mutually sliding structure with the first threaded shaft 202 through the bevel gear set 203 and the first motor 205. Through the setting of the bevel gear set 203, the bevel gear set 203 is connected between the first motor 205 and the first threaded shaft 202, and the rotation of the first motor 205 is transmitted to the first threaded shaft 202 through the bevel gear set 203, and the rotation direction of the motor is changed from vertical to horizontal, so as to drive the first threaded shaft 202 to rotate synchronously. At the same time, two groups of first threaded shafts 202 are provided in the mechanism, and the two groups of first threaded shafts 202 are connected through the bevel gear set 203. The bevel gear set 203 can distribute power to the two first threaded shafts 202, thereby realizing synchronous rotation of the two shafts. The synchronous motion ensures that the first threaded sleeve 204 and related components are smooth and not deflected when moving, avoiding the problem of jamming or inaccurate positioning.

[0028] Furthermore, one side of the belt 208 is embedded in the inside of the rotating groove 206, and the second threaded sleeve 209 forms a mutually sliding structure with the second motor 210 and the second threaded shaft 207 through the belt 208. Through the setting of the belt 208, the belt 208 is connected between the second motor 210 and the second threaded shaft 207. When the second motor 210 is started, the belt 208 transmits the rotational power of the second motor 210 to the second threaded shaft 207, thereby driving the second threaded shaft 207 to rotate. The belt 208 transmission is a flexible transmission method. Compared with the gear transmission, it has better buffering and shock absorption capabilities, which can effectively reduce the noise and vibration generated during the transmission process, thereby improving the stability of the transmission system. Finally, since the belt 208 transmission can transmit power between different axes, it can adapt to more complex spatial layout requirements. In this mechanism, the use of the belt 208 allows the second motor 210 to be flexibly arranged in a suitable position without being restricted by the threaded shaft and other structures.

[0029] Furthermore, the detection mechanism 3 includes a scale 301, a display screen 302, a connecting plate 303, a cylinder 304, a mounting plate 305, and an optical sensor 306. The scale 301 is fixedly connected to one side of the surface of the workbench 1, and a display screen 302 is installed at one end of the workbench 1. One side of the second threaded sleeve 209 is connected to the connecting plate 303, and the other side of the connecting plate 303 is installed with the cylinder 304. The other side of the cylinder 304 is fixedly connected to the mounting plate 305, and the optical sensor 306 is installed inside the mounting plate 305. The connecting plate 303, the cylinder 304, the mounting plate 305, and the optical sensor 306 are arranged. The detection mechanism 3 slides through the linkage with the moving mechanism 2. The second threaded sleeve 209 is connected to the connecting plate 303. The connecting plate 303 drives the cylinder 304 and the mounting plate 305 to move. The optical sensor 306 is installed on the mounting plate 305. The cylinder 304 is used to adjust the position of the optical sensor 306 to achieve accurate alignment with the object to be measured. The optical sensor 306 can capture the detection data and transmit the data to the display screen 302. The display screen 302 displays the measurement results in real time.

[0030] Furthermore, four groups of scales 301 are provided, and the scales 301 are provided around the workbench 1. Through the setting of the scales 301, the scales 301 are provided around the workbench 1 for measuring and indicating the position of the detection mechanism 3. Through the precise scale of the scales 301, real-time position monitoring of the detection mechanism 3 during movement can be achieved, which can ensure that the detection mechanism 3 maintains precise positioning during movement to avoid offset or error. At the same time, the scales 301 work in conjunction with the optical sensor 306. The optical sensor 306 can read the scale information on the scale 301, thereby accurately recording the current position of the detection mechanism 3. The existence of the scale 301 provides a standard reference for the optical sensor 306, ensuring measurement accuracy during movement and detection.

[0031] Furthermore, two groups of cylinders 304 are provided, and the mounting plate 305 and the optical sensor 306 form a mutually sliding structure through the cylinder 304 and the second threaded sleeve 209. Through the setting of the cylinder 304, the cylinder 304 is connected to the connecting plate 303. By pushing the connecting plate 303, the mounting plate 305 and the optical sensor 306 are driven to move linearly along the second threaded shaft 207. The driving force of the cylinder 304 can realize the precise movement of the detection mechanism 3, ensuring that the optical sensor 306 performs detection work at different positions.

[0032] Furthermore, two groups of optical sensors 306 are provided, and the optical sensors 306 are electrically connected to the display screen 302. Through the setting of the optical sensors 306, the optical sensors 306 realize accurate measurement of the object by sensing the specific characteristics of the object to be measured (such as size, shape, displacement, etc.). It can capture and analyze the characteristics of the object with high precision, and transmit the measurement data to the display screen 302 or the control system for real-time display and processing. At the same time, the optical sensors 306 are electrically connected to the display screen 302, and can feed back the detected data to the control system in real time. The control system automatically adjusts the position of the moving mechanism 2 or the detection mechanism 3 according to the information fed back by the sensor, thereby ensuring the accuracy and stability of the detection process. This feedback mechanism ensures that the system can be dynamically adjusted to avoid detection deviations.

[0033] Working principle: When the first motor 205 is started, the first motor 205 drives the bevel gear set 203 to rotate, thereby causing the first threaded shaft 202 to rotate synchronously, so that the rotation of the first threaded shaft 202 can drive the first threaded sleeve 204 to move along the first threaded shaft 202. Thereafter, when the second motor 210 is started, the belt 208 drives the second threaded shaft 207 to rotate, causing the second threaded sleeve 209 to slide along the second threaded shaft 207, thereby achieving further fine movement. The two groups of the first threaded shaft 202 rotate synchronously, and the precise movement of the moving mechanism 2 is achieved through the cooperation of the bevel gear set 203 and the first motor 205. The second threaded shaft 20 The sliding of 7 further provides a fine-tuning function to ensure that the detection mechanism 3 can be adjusted as needed. The detection mechanism 3 slides through the linkage with the moving mechanism 2. The second threaded sleeve 209 is connected to the connecting plate 303. The connecting plate 303 drives the cylinder 304 and the mounting plate 305 to move. An optical sensor 306 is installed on the mounting plate 305. The cylinder 304 is used to adjust the position of the optical sensor 306 to achieve accurate alignment with the object to be measured. The optical sensor 306 can capture detection data and transmit the data to the display screen 302. The display screen 302 displays the measurement results in real time. The model of the optical sensor 306 is Banner LE550.
