Description

Technical Field

[0001] The present invention relates to the technical field of headlight processing and installation, and specifically to an automatic locking device for headlight adjusting nuts. Background Art

[0002] As an important part of automobiles, headlights are also developing rapidly. The production and manufacturing equipment of headlights is an important part to ensure the production capacity and quality of headlights. The automatic locking device for adjusting nuts of headlights uses the adjusting nuts to install the lights on the vehicle and can adjust the position of the headlights to ensure uniform gaps between the headlights and the vehicle body and beautiful appearance.

[0003] When connecting the adjusting nut to the headlight, it is difficult to make the torsional distance between the adjusting nut and the headlight uniform when manually adjusting the adjusting nut by hand. When using auxiliary tools for processing, it is also difficult to control the locking depth of the adjusting nut, making it difficult to control the processing accuracy and quality. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic locking device for headlight adjusting nuts to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] An automatic locking device for headlight adjusting nuts includes a headlight, an adjusting nut, a pressing mechanism, a sensing mechanism, a positioning mechanism, a mounting seat, a driving mechanism, a propulsion cylinder, a bearing and a base, and the base is placed horizontally;

[0007] A propulsion cylinder is provided on the top of the base, a mounting seat is provided at the output end of the propulsion cylinder, a bearing is provided on the side of the mounting seat away from the propulsion cylinder, a driving mechanism is provided on one side of the bearing, a positioning mechanism is provided on the output shaft of the driving mechanism, an adjusting nut is provided on one side of the positioning mechanism, a headlight is provided at one end of the adjusting nut, a pressing mechanism is provided on the top of the headlight, and a sensing mechanism is provided on the upper surface of the base.

[0008] The pressing mechanism includes a hydraulic cylinder. The bottom end of the hydraulic cylinder is connected to the base. A clamping rod is provided at the top end of the hydraulic cylinder. A cushion block is provided at one end of the clamping rod away from the hydraulic cylinder. A positioning seat is provided at the bottom of the cushion block. The bottom of the positioning seat is connected to the base. A clamping groove is formed at the top of the positioning seat. The positioning seat is connected to the vehicle lamp through the clamping groove. The bottom of the cushion block is connected to the vehicle lamp. The cushion block is made of rubber and plastic materials. The vehicle lamp is clamped through the clamping groove at the top of the positioning seat. The movable block cooperates with the clamping groove to limit the shaking position of the vehicle lamp. Then, the hydraulic cylinder contracts to drive the clamping rod to descend, so that the cushion block at one end of the clamping rod clamps the vehicle lamp. Through the setting of the inner wall arc of the clamping groove, the center of the mounting adjustment nut on one side of the vehicle lamp is determined. Through the contact of the movable block and the cushion block with the vehicle lamp, the shaking of the vehicle lamp is reduced, and the precision of the installation of the adjustment nut and the vehicle lamp by the device is improved.

[0009] The sensing mechanism includes a displacement sensor. The bottom of the displacement sensor is connected to the base. A clamping cover is provided at the top of the displacement sensor. One side of the displacement sensor is connected to the mounting seat. The displacement sensor is electrically connected to the propulsion cylinder. The propulsion cylinder is started to drive the driving mechanism to move horizontally through the mounting seat. At the same time, the mounting seat squeezes the displacement sensor under the push of the propulsion cylinder. The displacement sensor is electrically connected to the propulsion cylinder, so that the displacement sensor controls the propulsion cylinder to stop running after being squeezed by a certain distance, ensuring the uniformity of the installation position of the adjustment nut.

[0010] The driving mechanism includes a driving motor. The driving motor is connected to the mounting seat. A connecting collar is provided on the output shaft of the driving motor. A connecting clamping rod is installed on the output shaft of the driving motor through the connecting collar. One end of the connecting clamping rod is connected to a bearing. The connecting collar is connected and fastened to one end of the connecting clamping rod through bolts. The driving motor and the connecting clamping rod are disassembled by rotating the bolts on one side of the connecting collar, which is convenient for the user to repair and replace the connecting clamping rod. The rotation position of the connecting clamping rod is restricted by the bearing, ensuring the rotational stability of the connecting clamping rod.

[0011] The positioning mechanism includes a housing, one side of which is connected to a connecting rod, an inner wall of the housing provided with a guide rod, one end of which is connected to the inner wall of an adjusting nut, a plurality of grooves equidistantly formed on the outer wall of the guide rod, a slider provided at one end of the guide rod through the groove, the slider being wedge-shaped, a rotating rod hinged at the bottom of the slider, one end of which is hinged to a bottom rack, a movable spring provided at the bottom of the bottom rack, one end of the movable spring being connected to the bottom rack, and the other end of the movable spring being connected to the housing. The adjusting nut is slid along the guide rod so that the adjusting nut drives the slider to slide along the groove, and the slider is wedge-shaped so that it contacts the inner wall of the adjusting nut while sliding along the groove. The sliders are evenly distributed equidistantly around the outer wall of the guide rod so that the center of the adjusting nut coincides with the center of the guide rod, thereby ensuring stable torsional installation of the adjusting nut and the headlight.

[0012] A step gear set is provided on the top of the bottom rack, and the step gear set is connected to the housing. The step gear set includes a first gear and a second gear. One side of the first gear is connected to the second gear. The central rotation axes of the first gear and the second gear coincide with each other. The radius of the first gear is smaller than the radius of the second gear. The second gear meshes with the bottom rack. A top rack is provided on the top of the first gear. When the slider slides downward, it drives the rotating rod to deflect, so that the other end of the rotating rod pushes the bottom rack to slide, so that the bottom rack squeezes the movable spring, so that the slider generates an upward thrust on the adjustment nut. At the same time, the bottom rack drives the step gear set to rotate, the bottom rack drives the second gear to rotate, and the second gear drives the first gear to rotate, so that the first gear drives the top rack to move slowly, which facilitates the user to plug the adjustment nut and the positioning mechanism.

[0013] A resistance spring is installed at the top of the top rack, with baffles at both ends. One end of the resistance spring is connected to the top rack, and the other end is connected to the housing. Six clamping plates are provided at one end of the top rack, and are equidistantly distributed around the inner wall of the housing. The top rack is driven by a step-type gear train, which simultaneously drives the clamping plates to clamp the adjustment nut. This allows the clamping plates to be quickly fixed according to the size of the adjustment nut, reducing the shaking caused by the housing-driven rotation of the adjustment nut and ensuring stable installation of the adjustment nut.

[0014] A trapezoidal block is provided at the top of the clamping plate. The clamping plate is connected to the adjusting nut through the trapezoidal block, and the adjusting nut is threadedly connected to the vehicle lamp. By driving the motor to drive the positioning mechanism to rotate, the adjusting nut in the positioning mechanism is quickly connected to the vehicle lamp. At the same time, the displacement sensor controls the movement of the propulsion cylinder. After the positioning mechanism moves to the specified position, the driving motor continues to rotate, causing the adjusting nut to drive the clamping plate to move, so that the clamping plate drives the top rack to disengage from the engagement with the stepped gear set. The active spring in the compressed state pushes the bottom rack to move horizontally, causing the slider to push the adjusting nut outwards quickly. The adjusting nut squeezes the clamping plate outwards through the trapezoidal block at one end of the clamping plate, so that the adjusting nut quickly disengages from the positioning mechanism and at the same time the top rack squeezes the abutting spring, causing the top rack to quickly return to its original position.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0016] 1. Through the settings of the vehicle lamp, adjusting nut, pressing mechanism, sensing mechanism, positioning mechanism, mounting seat, driving mechanism, propulsion cylinder and bearing, during the installation process of the adjusting nut and the vehicle lamp, the displacement sensor can ensure good locking accuracy between the adjusting nut and the vehicle lamp. The detection of the displacement sensor can ensure the locking depth. The stable rotation of the adjusting nut by the driving motor and the bearing ensures the locking perpendicularity of the adjusting nut. By restricting the moving direction of the adjusting nut by the guide rod in the positioning mechanism, the problem of the adjusting nut shaking during locking is avoided, improving the precision of the device.

[0017] 2. Through the settings of the positioning mechanism, adjusting nut, vehicle lamp, pressing mechanism and driving mechanism, it is convenient for the user to quickly place the adjusting nut. By inserting the middle hole of the adjusting nut onto the guide rod, the slider quickly clamps the middle hole of the adjusting nut, and at the same time drives the clamping plate to clamp the adjusting nut, saving the operation time of the staff, improving the working efficiency of the device, and at the same time making the center point of the adjusting nut quickly coincide with the center point of the guide rod, quickly positioning the installation position of the adjusting nut and the vehicle lamp, further improving the precision of the device.

[0018] 3. Through the settings of the vehicle lamp, adjusting nut, pressing mechanism, sensing mechanism, positioning mechanism, mounting seat and driving mechanism, after the positioning mechanism moves to the specified distance, the driving motor continues to rotate, causing the adjusting nut to push the clamping plate to move, so that the clamping plate drives the top rack to disengage from the engagement with the stepped gear set. The active spring in the compressed state pushes the bottom rack to move horizontally, causing the slider to push the adjusting nut outwards quickly. The disengaged top rack is disengaged from the clamping connection with the adjusting nut under the action of centrifugal force, so that the adjusting nut quickly disengages from the clamping connection of the positioning mechanism, further improving the working efficiency of the device, and at the same time avoiding the problem of the adjusting nut continuing to rotate under the action of inertia and causing wear to the vehicle lamp.

The cushion block 303 is made of rubber and plastic materials. The vehicle lamp 1 is clamped through the clamping groove 306 at the top of the positioning clamping seat 304. The movable stop block 305 cooperates with the clamping groove 306 to limit the shaking position of the vehicle lamp 1. Then, the hydraulic cylinder 301 contracts to drive the clamping rod 302 to descend, so that the cushion block 303 at one end of the clamping rod 302 clamps the vehicle lamp 1. Through the setting of the inner wall arc of the clamping groove 306, the center of the circle for installing the adjusting nut 2 on one side of the vehicle lamp 1 is determined.

[0045] The sensing mechanism 4 includes a displacement sensor 401. The bottom of the displacement sensor 401 is connected to the base 10. A clamping cover 402 is provided at the top of the displacement sensor 401. One side of the displacement sensor 401 is connected to the mounting seat 6. The displacement sensor 401 is electrically connected to the propulsion cylinder 8. When the propulsion cylinder 8 is started, the driving mechanism 7 is driven to move horizontally through the mounting seat 6. At the same time, the mounting seat 6 squeezes the displacement sensor 401 under the push of the propulsion cylinder 8. The displacement sensor 401 is electrically connected to the propulsion cylinder 8, so that the displacement sensor 401 controls the propulsion cylinder 8 to stop running after being squeezed by a certain distance, ensuring the unity of the installation position of the adjusting nut 2.

[0046] The positioning mechanism 5 includes a shell 501, one side of the shell 501 is connected to the connecting rod 703, and a guide rod 502 is provided on the inner wall of the shell 501.

The adjusting nut 2 is slid along the guide rod 502, so that the adjusting nut 2 drives the slider 5010 to slide along the groove. At the same time, the slider 5010 is set to be wedge-shaped. When the slider 5010 slides along the groove, it resists the inner wall of the adjusting nut 2. The sliders 5010 are evenly distributed around the outer wall of the guide rod 502 at equal distances, so that the center of the adjusting nut 2 coincides with the center of the guide rod 502, ensuring the stable torsional installation of the adjusting nut 2 and the headlight 1.

[0047] A step gear set 506 is provided on the top of the bottom rack 504, and the step gear set 506 is connected to the shell 501. The step gear set 506 includes a first gear 5061 and a second gear 5062. One side of the first gear 5061 is connected to the second gear 5062. The central rotation axes of the first gear 5061 and the second gear 5062 coincide with each other. The radius of the first gear 5061 is smaller than the radius of the second gear 5062. The second gear 5062 is meshed with the bottom rack 504. A top rack 507 is provided on the top of the first gear 5061. When the slider 5010 slides downward, it drives the rotating rod 503 to deflect, so that the other end of the rotating rod 503 pushes the bottom rack 504 to slide, so that the bottom rack 504 squeezes the movable spring 505, so that the slider 5010 generates a thrust on the adjusting nut 2. At the same time, the bottom rack 504 drives the ladder gear set 506 to rotate, and the bottom rack 504 drives the second gear 5062 to rotate, and the second gear 5062 drives the first gear 5061 to rotate, so that the first gear 5061 drives the top rack 507 to move slowly, which is convenient for the user to plug the adjusting nut 2 and the positioning mechanism 5.

[0048] A contact spring 508 is provided at the top of the top rack 507. Baffles are provided at both ends of the contact spring 508.

A connecting sleeve 702 is provided on the output shaft of the driving motor 701. A connecting rod 703 is installed on the output shaft of the driving motor 701 through the connecting sleeve 702. One end of the connecting rod 703 is connected to the bearing 9. The connecting sleeve 702 is connected and fastened to one end of the connecting rod 703 by bolts. The driving motor 701 and the connecting rod 703 are disassembled by rotating the bolts on one side of the connecting sleeve 702, which is convenient for the user to repair and replace the connecting rod 703. The rotation position of the connecting rod 703 is restricted by the bearing 9, ensuring the rotational stability of the connecting rod 703.

[0050] The driving motor 701 drives the positioning mechanism 5 to rotate, so that the adjusting nut 2 in the positioning mechanism 5 is quickly connected to the vehicle lamp 1. At the same time, the displacement sensor 401 controls the movement of the propulsion cylinder 8. After the positioning mechanism 5 moves to the designated position, the driving motor 701 continues to rotate, so that the adjusting nut 2 drives the clamping plate 509 to move, so that the clamping plate 509 drives the top rack 507 to disengage from the stepped gear set 506. The active spring 505 in the compressed state pushes the bottom rack 504 to move horizontally, so that the slider 5010 pushes the adjusting nut 2 out quickly. The adjusting nut 2 extrudes the clamping plate 509 through the trapezoidal block at one end of the clamping plate 509, so that the adjusting nut 2 quickly disengages from the positioning mechanism 5. At the same time, the top rack 507 squeezes the contact spring 508, so that the top rack 507 quickly returns to its original position.

[0051] The working principle of the present invention:

[0052] First, the vehicle lamp 1 is clamped by the pressing mechanism 3. The vehicle lamp 1 is clamped through the clamping groove 306 at the top of the positioning clamping seat 304. The movable stop block 305 cooperates with the clamping groove 306 to limit the shaking position of the vehicle lamp 1. Subsequently, the hydraulic cylinder 301 contracts to drive the clamping rod 302 to descend, so that the cushion block 303 at one end of the clamping rod 302 clamps the vehicle lamp 1. Through the setting of the inner wall arc of the clamping groove 306, the center of the mounting adjustment nut 2 on one side of the vehicle lamp 1 is determined. Through the contact of the movable stop block 305 and the cushion block 303 with the vehicle lamp 1, the shaking of the vehicle lamp 1 is reduced, and the cushion block 303 buffers the shaking of the vehicle lamp 1;

[0053] Subsequently, the adjustment nut 2 is placed on the positioning mechanism 5. The middle hole of the adjustment nut 2 is inserted into one end of the guide rod 502, so that the adjustment nut 2 drives the slider 5010 on the guide rod 502 to slide along the groove. The slider 5010 is set as a wedge shape. While the slider 5010 slides along the groove, it contacts the inner wall of the middle hole of the adjustment nut 2. The sliders 5010 are evenly distributed at equal intervals around the outer wall of the guide rod 502, so that the center of the adjustment nut 2 coincides with the center of the guide rod 502, quickly positioning the adjustment nut 2. While the slider 5010 slides downward, it drives the rotating rod 503 to deflect, so that the other end of the rotating rod 503 pushes the bottom rack 504 to slide. The bottom rack 504 presses the movable spring 505, so that the slider 5010 generates an upward thrust on the adjustment nut 2. At the same time, the bottom rack 504 drives the stepped gear set 506 to rotate. The bottom rack 504 drives the second gear 5062 to rotate, and the second gear 5062 drives the first gear 5061 to rotate, so that the first gear 5061 drives the top rack 507 to move slowly. The top rack 507 is driven to move by the stepped gear set 506. At the same time, the top rack 507 drives the clamping plate 509 to clamp the adjustment nut 2, so that the clamping plate 509 is quickly fixed according to the size of the adjustment nut 2. The clamping plate 509 clamps the adjustment nut 2 through the trapezoidal clamping block at one end, and at the same time generates a downward pulling force on the adjustment nut 2 through the contact spring 508, so that the positioning mechanism 5 stably clamps the adjustment nut 2;

[0054] Then, the adjustment nut 2 and the vehicle lamp 1 are installed. The propulsion cylinder 8 is started to drive the driving mechanism 7 to move horizontally through the mounting seat 6. At the same time, the mounting seat 6 presses the displacement sensor 401 under the push of the propulsion cylinder 8. The displacement sensor 401 is electrically connected to the propulsion cylinder 8, so that after the displacement sensor 401 is squeezed by a certain distance, the propulsion cylinder 8 is controlled to stop running, and the installation depth of the adjustment nut 2 and the vehicle lamp 1 is unified;

[0055] After the propulsion cylinder 8 stops pushing the driving mechanism 7 to move, the positioning mechanism 5 moves to the designated position. The driving motor 701 continues to rotate under the action of inertia. The adjusting nut 2 rotates on one side of the vehicle lamp 1, causing the adjusting nut 2 to drive the clamping plate 509 to move, so that the clamping plate 509 drives the top rack 507 to disengage from the engagement with the step gear set 506. The active spring 505 in the compressed state pushes the bottom rack 504 to move horizontally, causing the slider 5010 to push the adjusting nut 2 out quickly. The centrifugal force generated by the rotation on the clamping plate 509 causes the clamping plate 509 to disengage from the clamping connection with the adjusting nut 2, so that the adjusting nut 2 quickly disengages from the positioning mechanism 5. Subsequently, the top rack 507 squeezes the abutment spring 508, causing the top rack 507 to quickly return to its original position;

[0056] After the processing is completed, the driving mechanism 7 is driven by the propulsion cylinder 8 to contract, the positioning mechanism 5 is withdrawn, and at the same time, the clamping rod 302 at one end of the hydraulic cylinder 301 is raised to release the clamping of the vehicle lamp 1 by the cushion block 303. Subsequently, the processed vehicle lamp 1 is taken out.
