Description

Technical Field

[0001] The present application relates to the technical field of spring orientation recognition, and in particular to a spring orientation recognition mechanism for an automobile. Background Art

[0002] As an elastic element in the automobile suspension system, automobile suspension springs are mainly used to bear and transmit vertical loads, and to mitigate and suppress the impact caused by uneven roads. Automobile suspension springs have a specific structure with a central bend. Therefore, during the production process of automobile suspension springs, the springs need to be processed for orientation to accurately determine the bending mode of the springs and ensure that the springs can work in the predetermined direction during use, thereby ensuring the performance and service life of the springs. In the production of automobile suspension springs, orientation processing is particularly important because it directly affects the driving stability and ride comfort of the car.

[0003] At present, in order to ensure the correct direction of automobile suspension springs during production and assembly, the commonly used methods include manual identification and simple mechanical devices to assist in identification. Among them, manual identification is one of the most common methods. Workers judge the bending direction of the spring by visual inspection or feel, and place it in the specified position. Another method is to use some simple mechanical devices, such as fixed clamps or guide plates, to help workers perform identification operations more quickly. However, although these methods can solve the problem to a certain extent, they rely on the experience and skills of workers. They are not only inefficient, but also prone to misjudgment, resulting in the wrong direction of the spring, affecting the quality and reliability of the final product. Even if some simple mechanical devices are used as an aid, it is difficult to completely avoid the influence of human factors. Summary of the invention

[0022] The following will be combined with the attached Figure 1 -Attached Figure 5 , the technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0023] The inventor of the present application has found that the orientation recognition process of automobile suspension springs relies on manual experience, which is not only inefficient but also prone to misjudgment, resulting in the wrong direction of the spring, affecting the quality and reliability of the final product. To this end, the present application discloses an automobile spring orientation recognition mechanism, which mainly adopts the following scheme: The present application embodiment discloses a vehicle spring orientation recognition mechanism. Figure 1 and Figure 2 , including a frame 1, a material guide trough 2 installed at the exit of the tempering furnace, a movable frame 3 is slidingly arranged on the frame 1 in the horizontal direction, and a plurality of material receiving troughs 4 are fixedly arranged on the movable frame 3, and each material receiving trough 4 is evenly spaced along the sliding direction of the movable frame 3, and the material receiving trough 4 is inclined downward in the direction away from the material guide trough 2. In the embodiment of the present application, two material receiving troughs 4 are provided, and in other application embodiments, any number of material receiving troughs 4 can be provided.

[0024] Reference Figure 2 and Figure 3 The frame 1 is provided with a guide rail 11 for the movable frame 3 to slide, and a pneumatic cylinder 31 is fixedly installed on the movable frame 3. The piston rod of the pneumatic cylinder 31 is connected to the frame 1, and the movable frame 3 is driven to move horizontally on the frame 1 through the pneumatic cylinder 31. Furthermore, in order to accurately control the stroke of the movable frame 3, a stroke encoder (not shown in the figure) can also be installed on the frame 1.

[0025] Reference Figure 3 and Figure 4Two threaded rods 41 are rotatably arranged in the receiving trough 4. The length directions of the two threaded rods 41 are parallel. The two threaded rods 41 can be made of metal materials, such as stainless steel or aluminum alloy, with good wear resistance and corrosion resistance. The diameter of the threaded rod 41 can be selected according to actual needs, for example, the diameter is between 10mm and 20mm. The surface of the threaded rod 41 is provided with anti-slip grooves. The length of the threaded rod 41 should match the width of the receiving trough 4 to ensure that the spring does not fall off during the rotation process.

[0026] Reference Figure 4 The receiving trough 4 is provided with a driving device for driving the corresponding two threaded rods 41 to rotate in the same direction, and the driving device includes a driving gear 42, a driven gear 43 and a servo motor 44. The driving gear 42 is rotatably arranged on the receiving trough 4, and the two threaded rods 41 are coaxially fixed with the driven gear 43, and the driving gear 42 is respectively meshed with the driven gears 43 on the two threaded rods 41; the servo motor 44 is fixedly arranged on the moving frame 3, and the output shaft of the servo motor 44 is coaxially fixedly connected with the driving gear 42, and is used to drive the driving gear 42 to rotate.

[0027] Reference Figure 2 and Figure 4 , each receiving trough 4 is provided with a spring detection unit for detecting the spring, and the spring detection unit includes a pressure bearing plate 45. The pressure bearing plate 45 is fixedly arranged in the receiving trough 4 and is located on the side wall of the receiving trough 4 away from the guide trough 2. It can be made of stainless steel or aluminum alloy material, and the surface is polished to reduce friction. A gravity sensor is arranged on the pressure bearing plate 45, and the gravity sensor is electrically connected to a controller, and the controller is electrically connected to the pneumatic cylinder 31 and the servo motor 44 respectively. The spring is output from the tempering furnace, and the spring falls into the receiving trough 4 through the guide trough 2 at the outlet of the tempering furnace. When the spring falls into the receiving trough 4, it contacts the pressure bearing plate 45 under the action of gravity. The gravity sensor detects the spring, and the controller controls the pneumatic cylinder 31 to start, driving the moving frame 3 to move horizontally, so that other receiving troughs 4 without springs are moved to the outlet position of the tempering furnace. At this time, the tempering furnace continues to output a spring. After the springs are loaded in each receiving trough 4 , the controller controls each servo motor 44 to start, and respectively drives the two threaded rods 41 in the corresponding positioning groove to rotate, thereby driving the spring to rotate in the receiving trough 4 .

[0028] Reference Figure 3, a photoelectric sensing device 46 is also provided in the receiving trough 4. The photoelectric sensing device 46 is installed between the two threaded rods 41 and is used to detect the bending direction of the spring. The photoelectric sensing device 46 is electrically connected to the controller. The photoelectric sensing device 46 uses a highly sensitive infrared photoelectric sensor. The photoelectric sensing device 46 detects the number of turns used when the spring rotates to the set position, thereby determining the bending direction of the spring, and then realizing the recognition of the spring. Specifically, when the spring rotates in the receiving trough 4 to a state where the middle part bulges upward, the photoelectric sensing device 46 immediately controls the spring to stop rotating through the controller. At this time, the bending direction of the spring is determined according to the different number of turns of the spring. For example, when the spring bends to the right, the number of turns detected by the photoelectric sensing device 46 is 0-1; when the spring bends to the left, the number of turns detected by the photoelectric sensing device 46 is 1-2.

[0029] After the spring orientation is completed, the spring is taken out from the receiving trough 4, and the spring is output from the tempering furnace again and enters the receiving trough 4 to continue the orientation. The orientation recognition mechanism of the present application can also be used together with a manipulator to facilitate the spring to be taken out from the receiving trough 4 after the spring orientation is completed. Furthermore, the controller can also be electrically connected to the chain plate conveyor at the outlet of the tempering furnace to control the output of the spring from the tempering furnace, thereby realizing linkage with the orientation recognition mechanism.

[0030] Reference Figure 4 and Figure 5 , a slide groove 47 is provided on the bottom wall of the feeding trough along the length direction of the threaded rod 41, an adjustment block 48 is slidably arranged in the slide groove 47, a photoelectric sensing device 46 is mounted on the adjustment block 48, and an adjustment assembly for driving the adjustment block 48 to slide along the length direction of the threaded rod 41 is arranged on the mobile frame 3, and the adjustment assembly includes an adjustment screw 32 and a rotating handle 33, the adjustment screw 32 is rotatably arranged on the mobile frame 3, and the length direction of the adjustment screw 32 is parallel to the length direction of the threaded rod 41. The adjustment screw 32 is threadedly matched with the adjustment block 48, and the rotating handle 33 is coaxially fixedly connected with the adjustment screw 32. By arranging the adjustment block 48 in the receiving trough 4, the adjustment block 48 can slide along the length direction of the threaded rod 41, so that the position of the photoelectric sensing device 46 can be adjusted according to actual needs. This improves the flexibility and adaptability of the photoelectric sensing device 46, and can better detect springs of different sizes and shapes, ensuring the accuracy of the detection results.

[0031] Reference Figure 3 and Figure 4The stopper frame 34 is provided with a slidable structure on the movable frame 3 to prevent the spring from popping out of the material receiving trough 4 when the spring falls into the material receiving trough 4. Each material receiving trough 4 is located in the stopper frame 34. Baffles 341 are fixedly provided on the stopper frame 34 and on both sides of each material receiving trough 4. A servo cylinder 35 is provided on the movable frame 3 to drive the stopper frame 34 to slide. The servo cylinder 35 is rotatably arranged on the movable frame 3, and a top support rod 351 is fixedly provided on the piston rod of the servo cylinder 35. The top support rod 351 is hinged to the stopper frame 34, and the servo cylinder 35 is electrically connected to the controller. The stopper frame 34 can be raised before the spring falls to ensure that the spring will not fall out of the material trough due to the height difference when it falls from the exit of the tempering furnace to the material receiving trough 4. When the spring enters the material receiving trough 4, the stopper frame 34 descends, so that the spring can be taken out of the material receiving trough 4 after the spring recognition is completed. Furthermore, by rotatably setting the servo cylinder 35 on the moving frame 3, and by setting the supporting rod 351, and hingedly connecting the supporting rod 351 and the material blocking frame 34, installation errors can be effectively avoided.

[0032] The implementation principle of the automobile spring recognition mechanism of the embodiment of the present application is as follows: the spring is output from the tempering furnace, passes through the guide groove 2 at the outlet of the tempering furnace, and falls into the receiving groove 4. After the spring falls into the receiving groove 4, the spring detection unit detects the spring, and the controller controls the pneumatic cylinder 31 to start, driving the moving frame 3 to move horizontally, so that other receiving grooves 4 without springs are moved to the outlet position of the tempering furnace. At this time, the tempering furnace continues to output a spring.

[0033] After the springs are loaded in each receiving slot 4, the controller controls each servo motor 44 to start, and drives the two threaded rods 41 in the corresponding positioning slots to rotate, thereby driving the spring to rotate in the receiving slot 4. When the spring reaches the set position, the photoelectric sensing device 46 is triggered, and the driving device is controlled by the controller to stop working, so that the spring stops rotating. At this time, the photoelectric sensing device 46 is triggered according to the number of turns used when the spring rotates to the set position, and the bending direction of the spring is determined, and the spring is recognized. After that, the spring is taken out of the receiving slot 4, and the spring is output again in the tempering furnace. The receiving slot 4 moves horizontally in the opposite direction and receives the next spring, and continues to recognize the direction of the spring; the automatic recognition of the automobile spring is realized, and the production efficiency and accuracy are improved.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
