Description

Technical Field

[0001] This utility model belongs to the field of detection device technology, specifically a detection device for the hole position of an automotive headlight bracket. Background Technology

[0002] With the rapid development of the automotive industry, the manufacturing precision and quality requirements of automotive parts are becoming increasingly stringent. As a key component of the automotive lighting system, the installation precision of automotive headlights directly affects the safety and aesthetics of the vehicle. As a crucial structure connecting the headlights to the vehicle body, the hole position precision of the headlight bracket is particularly important. With the continuous advancement of automotive manufacturing technology, the structure and materials of headlight brackets are also constantly changing. For example, modern automotive headlight brackets typically use high-strength plastics or aluminum alloys. These materials are prone to deformation and stress concentration during processing, further increasing the difficulty of hole position detection.

[0003] Existing automotive headlight bracket hole position detection devices have the following main shortcomings:

[0004] Existing automotive headlight bracket hole position detection devices lack multi-dimensional independent and precise adjustment structures, making it difficult to quickly and accurately move the detector to the position to be detected for different models of automotive headlight brackets. When different models of automotive headlight brackets have significantly different hole positions due to different design specifications, existing devices cannot adapt well and may cause misjudgments due to detection position deviations, affecting the accuracy of the detection results. Furthermore, they may not be able to firmly clamp the headlight bracket during the detection process, causing slight movement of the bracket and affecting the accuracy of the detection results. At the same time, if the clamping force is too large, it can easily damage the bracket, especially for brackets made of softer materials or with special shapes. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a device for detecting the hole position of an automotive headlight bracket. It solves the problem that the existing technology lacks a multi-dimensional independent and precise adjustment structure. When faced with brackets of different models with large differences in hole position, it is difficult to quickly and accurately move the detector into place. It is easy to make misjudgments due to position deviation, which affects the accuracy of detection. In addition, either it is difficult to clamp firmly, causing slight movement of the bracket to affect the results, or the clamping force is too large and damages soft or special-shaped brackets.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for detecting the hole position of an automotive headlight bracket, comprising a detection platform, a controller provided on one side of the upper surface of the detection platform near the front, a detection structure provided at the center of the upper surface of the detection platform near the rear, and a clamping structure provided at the center of the interior of the detection platform;

[0007] The detection structure includes a first slide groove, which is located at the rear center of the upper surface of the detection platform. A first motor is located at the rear upper end of one side wall of the detection platform. The output end of the first motor passes through one side wall of the detection platform and one side wall of the first slide groove and extends into the interior of the first slide groove. A first lead screw is fixedly connected to the end of the motor. A lifting frame is threaded onto the outer side wall of the first lead screw.

[0008] As a further embodiment of this utility model: a second sliding groove is provided at the upper center of the front end face of the lifting frame, and a second motor is provided at the front center of the upper end face of the lifting frame. The output end of the second motor passes through the upper end face of the lifting frame and the upper end face of the second sliding groove and extends into the interior of the second sliding groove, and a second lead screw is fixedly connected to the end of the motor.

[0009] As a further embodiment of this utility model: an adjustment frame is threaded onto the outer wall of the second lead screw, a third sliding groove is provided at the center of the lower end face of the adjustment frame, and a third motor is provided at the center of the front end face of the adjustment frame.

[0010] As a further embodiment of this utility model: the output end of the third motor passes through the front end face of the adjustment frame and the front end face of the third slide groove to the inside of the third slide groove, and a third lead screw is fixedly connected to the end. A slider is threaded on the outer wall of the third lead screw, and an infrared detector is provided at the center of the lower end face of the slider.

[0011] As a further embodiment of this utility model: the clamping structure includes a clamping cavity, which is located at the center of the inside of the testing platform. The upper surface of the testing platform is provided with two moving grooves in a cross shape, and a column is provided at the center of the inside of the clamping cavity.

[0012] As a further embodiment of this utility model: electric telescopic rods are provided at the center of the two inner side walls, the center of the front inner wall, and the center of the rear inner wall of the clamping cavity, and clamping plates are provided at the output ends of the four electric telescopic rods.

[0013] As a further embodiment of this utility model: compression springs are provided at the upper, lower, and front ends of the clamping plate near the center of one side wall of the clamping plate, near the center of the rear end face of the clamping plate, near the center of the rear end face of the clamping plate, near the center of the rear end face of the clamping plate, near the center of the front end face of the clamping plate, near the center of the rear end face of the clamping plate, and near the center of the rear end face of the clamping plate. The eight compression springs are arranged in groups of two, and each of the four groups of compression springs has a rubber plate at one end.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the first motor, second motor and third motor respectively driving the first lead screw, second lead screw and third lead screw to rotate, realizes independent and precise adjustment of the infrared detector in the lateral, lifting and lowering and front and back directions. It can move the detector to the position to be detected in the headlight bracket hole more accurately, which greatly improves the flexibility and accuracy of the detection position adjustment, reduces misjudgment caused by detection position deviation. When different models of car headlight brackets have different design specifications and large differences in hole position, the multi-dimensional adjustment structure of this device can quickly and accurately adapt to the detection needs of various headlight brackets of different specifications, ensuring the efficiency and accuracy of the detection work.

[0016] 2. This utility model utilizes an electric telescopic rod to extend and push the clamping plate close to the headlight bracket, providing basic clamping force. The compression spring plays a crucial role in buffering and fine-tuning, preventing damage to the headlight bracket due to excessive force during clamping. Simultaneously, it precisely adjusts the clamping force and position, compensating for gaps or deviations caused by irregular bracket shapes. The rubber plate better fits the headlight bracket, further enhancing clamping stability and reliability. This effectively avoids problems such as product damage from excessive clamping and testing deviations due to unstable clamping. It ensures the bracket's stable position throughout the testing process, providing a strong guarantee for obtaining accurate and reliable test results. This is particularly advantageous for automotive headlight brackets with irregular shapes and fragile materials, but requiring extremely high assembly precision. Attached Figure Description

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A device for detecting the hole position of an automotive headlight bracket, comprising:

[0025] The testing table 1 has a controller 2 located on one side of the upper surface of the testing table 1, a testing structure 3 located at the center of the upper surface of the testing table 1, and a clamping structure 4 located at the center of the interior of the testing table 1.

[0026] The detection structure 3 includes a first slide groove 301, which is located at the rear center of the upper surface of the detection table 1. A first motor 302 is located at the rear center of one side wall of the detection table 1. The output end of the first motor 302 passes through the side wall of the detection table 1 and the side wall of the first slide groove 301, and is fixedly connected to the end of the first lead screw 303. A lifting frame 304 is threaded onto the outer wall of the first lead screw 303. A second slide groove 305 is located at the upper center of the front face of the lifting frame 304. A second motor 306 is located at the front center of the upper surface of the lifting frame 304. The output end of the second motor 306 passes through the upper surface of the lifting frame 304 and is connected to the first lead screw 303. The upper end face of the second slide groove 305 extends into the interior of the second slide groove 305, and the end is fixedly connected to the second lead screw 307. The outer wall of the second lead screw 307 is threaded with an adjustment frame 308. The lower end face of the adjustment frame 308 is provided with a third slide groove 309 near the center. The front end face of the adjustment frame 308 is provided with a third motor 310 near the center. The output end of the third motor 310 passes through the front end face of the adjustment frame 308 and the front end face of the third slide groove 309 and extends into the interior of the third slide groove 309. The end is fixedly connected to the third lead screw 311. The outer wall of the third lead screw 311 is threaded with a slider 312. The lower end face of the slider 312 is provided with an infrared detector 313.

[0027] After the car headlight is placed on the testing platform 1, the first motor 302 is started to drive the first lead screw 303 to rotate, causing the lifting frame 304 to move along the first slide groove 301, adjusting the position of the infrared detector 313. Once the infrared detector 313 is in the appropriate position, the second motor 306 is started to drive the second lead screw 307 to rotate, causing the adjusting frame 308 to move up and down along the second slide groove 305, bringing the infrared detector 313 to the appropriate height. Once the infrared detector 313 is in the appropriate height, the third motor 310 is started to drive the third lead screw 311 to rotate, causing the slider 312 to move along the third slide groove 309, ultimately precisely adjusting the infrared detector 313 to the headlight bracket hole position to be tested. Once the infrared detector 313 is moved to the appropriate position, it is activated to detect the holes on the headlight bracket. The infrared detector 313 emits and receives infrared rays, and based on the feedback of the infrared signals, it determines whether the holes on the bracket are in the standard positions required by the design and whether there are any deviations. If the holes are not in the correct positions, the reflection and refraction of infrared rays will be different from the normal positions. The infrared detector 313 can detect this difference and transmit the detection results to the controller 2. The controller 2 receives the detection result signal transmitted by the infrared detector 313, analyzes, judges and processes the signal, and displays the final detection results. The operator can obtain information such as whether the headlight bracket holes are qualified through the controller 2.

[0028] The clamping structure 4 includes a clamping cavity 401, which is located at the center of the inside of the testing table 1. The upper surface of the testing table 1 has two moving slots 403 arranged in a cross shape. A column 402 is located at the center of the inside of the clamping cavity 401. Electric telescopic rods 404 are provided at the center of the two inner side walls, the center of the front inner wall, and the center of the rear inner wall of the clamping cavity 401. Each of the four electric telescopic rods 404 has a clamping plate 405 at its output end. The clamping plates 405 are located at the center of the side wall of the clamping plate 405 near the top, bottom, and front, and at the center of the rear end face of the clamping plate 405 near the top, bottom, and rear. Compression springs 406 are provided at the upper and lower center of the front end face of 405. The eight compression springs 406 are arranged in pairs. Each of the four sets of compression springs 406 has a rubber plate 407 at one end. By placing the car headlight bracket on the test platform 1, the four electric telescopic rods 404 extend and push the clamping plate 405 close to the headlight bracket. The compression springs 406 play a role in buffering and fine adjustment. At the same time, the rubber plate 407 can better fit the headlight bracket and firmly clamp it on the test platform 1, ensuring the stability of the bracket position during the test.

[0029] The working principle of this utility model is as follows: After the car headlight bracket is placed on the column 402, the four electric telescopic rods 404 are extended by activating them, pushing the clamping plate 405 at its output end closer to the headlight bracket. During this process, the compression spring 406 set on the clamping plate 405 plays a buffering role and can make fine adjustments to the clamping force and position, while the rubber plate 407 fits better with the headlight bracket, finally firmly clamping the headlight bracket on the column 402, ensuring that the bracket will not move arbitrarily during subsequent testing and ensuring the accuracy of the test.

[0030] After the headlight bracket is placed, the first motor 302 is started to drive the first lead screw 303 to rotate, causing the lifting frame 304 to move along the first slide groove 301, thereby initially adjusting the position of the infrared detector 313 in the horizontal direction. After the lifting frame 304 moves to the appropriate position, the second motor 306 is started to drive the second lead screw 307 to rotate, causing the adjusting frame 308 to move up and down along the second slide groove 305, so that the infrared detector 313 reaches the appropriate height position in the vertical direction. After the height of the infrared detector 313 is adjusted, the third motor 310 is started to drive the third lead screw 311 to rotate, causing the slider 312 to move back and forth along the third slide groove 309, finally precisely adjusting the infrared detector 313 to the position to be detected in the headlight bracket hole.

[0031] Once the infrared detector 313 is moved to the appropriate position, it is activated. The detector emits infrared rays and receives the reflected infrared signals. By analyzing the difference between the received signal and the expected normal position signal, it determines whether the holes on the headlight bracket are in the standard position required by the design and whether there is any deviation. The infrared detector 313 transmits the detection results to the controller 2 in the form of electrical signals. The controller 2 receives these detection result signals and performs a series of analyses, judgments, and processing on the signals. Finally, the operator can obtain information such as whether the headlight bracket holes are qualified through the controller 2, so as to know whether the car headlight bracket meets the quality requirements.

[0032] Furthermore, the control method of this utility model is controlled by controller 2. The control circuit of controller 2 can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0033] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
