Description

Technical Field

[0001] This application relates to the field of automotive parts processing technology, and in particular to an automotive grille processing apparatus. Background Technology

[0002] As an important exterior component at the front of a vehicle, the quality of the paint on the car grille directly affects the overall visual appeal and perceived quality of the vehicle. Currently, the common method for painting car grilles is to place the grille horizontally on a fixed rack or fixture, and then have it painted by operators or painting robots.

[0003] Due to the complex structure of the grille, with numerous perforations and deep grooves, the bottom edge of the grille and the inner wall of the groove become blind spots for spraying when fixed horizontally. The paint from the spray gun cannot effectively cover these areas, easily leading to missed areas. This not only affects the appearance quality of the product but also reduces the corrosion resistance of these areas. To ensure coating of the bottom and inner walls, operators often need to repeatedly flip and reposition the grille, or perform multi-angle, complex touch-up spraying operations around the workpiece, increasing the processing time per unit and reducing overall production efficiency. Utility Model Content

[0004] To address the issues of low bottom coverage and complex operation of grilles, this application provides an automotive grille processing apparatus.

[0005] The automotive grille processing device provided in this application adopts the following technical solution: An automotive grille processing device includes a placement platform and a support frame rotatably disposed with the placement platform. The support frame is provided with an auxiliary mechanism for tilting the grille during the painting process. The moving end of the auxiliary mechanism is provided with two support rods for driving the two ends of the grille to rise and fall in opposite directions. Each of the two support rods is provided with a limiting rod that hooks the grille by rotating in opposite directions.

[0006] By adopting the above technical solution, the placement platform and support frame provide a stable basic structure for the grille. The auxiliary mechanism drives the two support rods to move in opposite directions, causing the grille to tilt during the painting process. The spray gun can be aimed at the bottom and inner area of ​​the unfolded grille, improving the spray coverage. The bottom of the grille is directly exposed by the lifting and moving of the support rods, eliminating the need for the operator to flip the grille or find an angle around the bracket for touch-up spraying, saving time on flipping and touch-up spraying. During the tilting process, the arc end of a limiting rod hooks in the opposite direction, locking the grille from the inside like a safety hook to prevent the grille from falling.

[0007] Preferably, the auxiliary mechanism includes a self-locking motor fixedly connected to the support bone. A large bevel gear rotatably connected to the drive end of the self-locking motor is rotatably disposed inside the support bone. The large bevel gear is provided with a transmission group one and a transmission group two for reverse transmission. Two fixed cylinders are fixedly disposed on the support bone. Threaded rod one and threaded rod two are rotatably disposed inside the two fixed cylinders, respectively, penetrating the support bone. Movable cylinders rotatably connected to the inside of the support rod are slidably disposed outside both fixed cylinders. The movable cylinders are fixedly disposed with a limiting rod. Sliding grooves are provided on both fixed cylinders. Circular sleeves fixedly connected to the movable cylinders are slidably disposed in both sliding grooves. The two circular sleeves are threadedly connected to threaded rod one and threaded rod two, respectively. The support rod assists in supporting the grid through a telescopic structure.

[0008] By adopting the above technical solution, the large bevel gear diverts the power of the self-locking motor to both sides; the ingenious arrangement of transmission group one and transmission group two ensures that threaded rod one and threaded rod two receive driving forces in opposite directions of rotation; the fixed cylinder provides a stable installation foundation and guide; the annular sleeve meshes with the threaded rod, converting the rotational motion of the threaded rod into its own linear motion. The key function of the sliding groove is to restrict the circumferential rotation of the annular sleeve, forcing it to slide only along the groove. The movable cylinder ultimately transmits the linear motion to the support rod and the limiting rod, and the telescopic structure is used to improve flexible support and adaptability.

[0009] Preferably, the telescopic structure includes sliding columns fixedly disposed at both ends of the support rod, and a cylinder is slidably disposed outside both sliding columns.

[0010] By adopting the above technical solution, the sliding column and the cylinder form a specific and simple telescopic structure. It is low-cost, slides smoothly, and effectively achieves the aforementioned auxiliary support and adaptive functions.

[0011] Preferably, the chute is composed of a parallel section and a vertical section, and the parallel section and the vertical section of the chute are internally connected.

[0012] By adopting the above technical solution, the vertical section is used to realize the lifting and lowering of the movable cylinder, and the parallel section is used to realize the rotation of the limit rod.

[0013] Preferably, the transmission assembly one includes a small bevel gear one that meshes with the large bevel gear. The end of the small bevel gear one that is away from the large bevel gear passes through the interior of the support bone and is rotatably connected to the support bone. A bevel gear assembly one is fixedly provided at the end of the small bevel gear one that is away from the large bevel gear. The transmission end of the bevel gear assembly one is fixedly connected to the threaded rod one.

[0014] By adopting the above technical solution, the small bevel gear 1 causes the threaded rod 1 to rotate in the same direction through the bevel gear set 1.

[0015] Preferably, the transmission assembly two includes a small bevel gear two that meshes with the large bevel gear. The end of the small bevel gear two away from the large bevel gear passes through the interior of the support bone and is rotatably connected to the support bone. A bevel gear assembly two is fixedly provided at the end of the small bevel gear two away from the large bevel gear. The transmission end of the bevel gear assembly two is fixedly connected to the threaded rod two.

[0016] By adopting the above technical solution, the small bevel gear two causes the threaded rod two to rotate in the opposite direction to the threaded rod one through the bevel gear set two.

[0017] Preferably, auxiliary frames that are fixedly connected to the cylinder are fixedly provided on both sides of the supporting bone.

[0018] By adopting the above technical solution, the auxiliary frame extends the support point, expands the support range of the device, makes the grid more stable when tilted and less prone to shaking, and further improves the rigidity and reliability of the entire system during operation.

[0019] Preferably, the end of the limiting rod away from the support rod is arc-shaped.

[0020] By adopting the above technical solution, the arc shape is used to restrict the movement of the car grille.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By driving the threaded rods one and two to rotate in opposite directions through the large bevel gear, transmission group one, and transmission group two, the movable cylinders on both sides of the grille move in opposite directions, so that the grille is tilted during the painting process. The spray gun can be aimed at the bottom and inner area of ​​the unfolded grille, improving the spray coverage. The operator no longer needs to move and flip the grille repeatedly, or find the angle around the bracket for touch-up spraying, saving the time of flipping and touch-up spraying.

[0022] 2. The limiting rod adopts an arc-shaped top design. In the initial state, the two limiting rods bend in one direction to limit the position. When the grille tilts to the top, it slides through the ring sleeve on the top of the groove, triggering the limiting rod to turn 180 degrees. This causes the arc end of one limiting rod to hook in the opposite direction, locking the grille from the inside like a safety hook, preventing the grille from falling. This effectively avoids falling accidents caused by loose workpieces, spraying impacts, or mechanical vibrations. Attached Figure Description

[0025] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0026] This application discloses an automotive grille processing apparatus.

[0027] Reference Figure 1 , Figure 2 as well as Figure 4 An automotive grille processing device includes a placement platform 1 and a support frame 2 rotatably disposed with the placement platform 1. An auxiliary mechanism 3 is disposed within the support frame 2. The auxiliary mechanism 3 is used to tilt the grille during the painting process. The moving end of the auxiliary mechanism 3 is provided with two support rods 4, which are used to drive the two ends of the grille to rise and fall in opposite directions. Limiting rods 5 are inserted into both support rods 4. The limiting rods 5 can be disassembled. The limiting rods 5 hook the grille by rotating in the opposite direction. The end of the limiting rod 5 away from the support rod 4 is arc-shaped. The arc shape can prevent the grille from being easily lifted and dropped. The two support rods 4 and the limiting rods 5 achieve dual positioning of the automotive grille.

[0028] First, the operator places the car grille on two support rods 4. The two support rods 4 must be stably placed with the grille, and the center of the support rods 4 should correspond to the center of the grille to prevent the grille from tilting. Initially, the arcs of the two limiting rods 5 face the same direction, and the arc width of the limiting rods 5 is smaller than the slot of the car grille. In this way, the grille can be placed directly through the limiting rods 5 on the support rods 4. Then, the grille is moved so that the limiting rods 5 are located in the center of the slot of the car grille. At this time, the arc end of the limiting rod 5 restricts the top of the grille. Through the auxiliary mechanism 3, the grille can be tilted during the painting process. The spray gun can be aimed at the bottom and inner area of ​​the unfolded grille to improve the spray coverage and reduce the generation of dead corners. During the tilting process, the arc end of one of the limiting rods 5 hooks in the opposite direction, like a safety hook, locking the grille from the inside to prevent the grille from falling. The support bone 2 supports the entire car grille, and the support end of the placement platform 1 extends to the painting position.

[0029] Reference Figure 3 , Figure 4 as well as Figure 7 The auxiliary mechanism 3 includes a self-locking motor 31 fixedly connected to the support rib 2. The mounting end of the self-locking motor 31 is fixed to the surface of the support rib 2. The interior of the support rib 2 is rotatably connected to the bottom end of the large bevel gear 32. The bottom end of the large bevel gear 32 is connected to the drive end of the self-locking motor 31 through a coupling. The large bevel gear 32 is provided with a transmission group 1 33 and a transmission group 2 34. The transmission group 1 33 and the transmission group 2 34 are used to realize reverse transmission, thereby causing the two support rods 4 to move in opposite directions, causing the grid to tilt. The upper surface of the support rib 2 is fixed to the lower surface of the two fixed cylinders 37. The two fixed cylinders 37 are respectively provided with The device is equipped with a threaded rod 35 and a threaded rod 36, both of which penetrate the interior of the support rib 2 and are rotatably connected to it. The outer walls of the two fixed cylinders 37 slide against the inner wall of a movable cylinder 38 without gaps, preventing paint from entering between the fixed cylinders 37 and the movable cylinder 38. The top of the movable cylinder 38 is rotatably connected to the bottom of the support rod 4. The upper surface of the movable cylinder 38 is coaxially fixed with the lower surface of the limiting rod 5. Both fixed cylinders 37 are provided with a sliding groove 39, which consists of a parallel section and a vertical section. The tops of the parallel section and the vertical section of the sliding groove 39 are internally connected.

[0030] In the initial state, there is space between the top of the fixed cylinder 37 and the movable cylinder 38, and the bottom of the movable cylinder 38 is located in the middle of the fixed cylinder 37. After the upper surface of the grille is painted, the operator starts the self-locking motor 31. The self-locking motor 31 drives the large bevel gear 32 to rotate. The rotation of the large bevel gear 32 causes the threaded rod 35 and the threaded rod 36 to rotate in opposite directions through the transmission group 1 33 and the transmission group 2 34. For example, when the threaded rod 35 rotates clockwise, the movable cylinder 38 located outside the threaded rod 35 drives one support rod 4 to rise. When the threaded rod 36 rotates clockwise, the movable cylinder 38 located outside the threaded rod 36 drives another support rod 4 to fall. The grille presents an inclined posture with the left side lower and the right side higher. The spray gun can be aimed at the bottom edge of the grille to achieve spraying. The fixed cylinder 37 uses a high-strength engineering plastic material (such as polyethylene) with a low coefficient of sliding friction to ensure low friction and high durability of the chute 39 during long-term operation.

[0031] Reference Figure 4 , Figure 5 as well as Figure 6 Both grooves 39 slide against the outer wall of the annular sleeve 310. One end of the annular sleeve 310 outside the fixed cylinder 37 is fixed to the inner wall of the movable cylinder 38. The length of the movable cylinder 38 needs to be designed to be more than twice the length of the groove 39. The annular sleeve 310 is fixed in the middle of the movable cylinder 38. In this way, the groove 39 will not be exposed when the movable cylinder 38 slides, thus preventing paint from entering. The two annular sleeves 310 are threadedly connected to the threaded rod 1 35 and the threaded rod 2 36 respectively. The support rod 4 assists in supporting the grid through a telescopic structure. The telescopic structure includes sliding columns 311 fixed to both ends of the support rod 4. The outer walls of the two sliding columns 311 slide against the inner wall of a cylinder 312 respectively. Both sides of the support bone 2 are fixed to the surface of an auxiliary frame 6. The upper surface of the auxiliary frame 6 is fixed to the bottom of the cylinder 312.

[0032] In the initial state, the annular sleeve 310 is located above the middle of the threaded rod 35 or the threaded rod 36. When the threaded rod 35 or the threaded rod 36 rotates, it will cause the annular sleeve 310 to rise or fall. The annular sleeve 310 slides on the vertical section of the slide groove 39, thereby causing the movable cylinder 38 to rise or fall. When the annular sleeve 310 slides on the parallel section of the slide groove 39, when the threaded rod 35 or the threaded rod 36 rotates, it will cause the annular sleeve 310 to rotate and slide inside the parallel section of the slide groove 39, thereby causing the movable cylinder 38 to rotate. The rotation of the movable cylinder 38 will cause the limiting rod 5 to rotate, thereby the limiting rod 5 will hook the grid in the opposite direction to prevent it from sliding down and falling.

[0033] Reference Figure 3The transmission assembly 33 includes a small bevel gear 331 that meshes with the top of the large bevel gear 32. The end of the small bevel gear 331 away from the large bevel gear 32 passes through the interior of the support bone 2. The small bevel gear 331 is rotatably connected to the support bone 2. The bevel gear assembly 332 consists of two bevel gears. The small bevel gear 331 and the vertical bevel gear in the bevel gear assembly 332 are coaxially fixed. The bevel gear assembly 332 is located at the end of the small bevel gear 331 away from the large bevel gear 32. The parallel bevel gear in the bevel gear assembly 332 is coaxially fixed to the outer surface of the threaded rod 35. Transmission assembly 2 34 includes a small bevel gear 2 341 that meshes with the top of the large bevel gear 32. The end of the small bevel gear 2 341 away from the large bevel gear 32 passes through the interior of the support bone 2. The small bevel gear 2 341 is rotatably connected to the support bone 2. The bevel gear assembly 2 342 is also composed of two bevel gears. The small bevel gear 2 341 and the vertical bevel gear in the bevel gear assembly 2 342 are coaxially fixed. The bevel gear assembly 2 342 is located at the end of the small bevel gear 2 341 away from the large bevel gear 32. The parallel bevel gear in the bevel gear assembly 2 342 is coaxially fixed with the lower surface of the threaded rod 2 36. The bevel gear assembly 1 332 and the bevel gear assembly 2 342 are arranged in opposite directions.

[0034] While the large bevel gear 32 rotates, it drives the small bevel gear 1 331 and the small bevel gear 2 341 to rotate. The small bevel gear 1 331 and the small bevel gear 2 341 rotate in opposite directions. The rotation of the small bevel gear 1 331 drives the bevel gear set 1 332 to drive the threaded rod 1 35 to rotate. The rotation of the small bevel gear 2 341 drives the bevel gear set 2 342 to drive the threaded rod 2 36 to rotate. Through the reverse setting of the bevel gear set 1 332 and the bevel gear set 2 342, the threaded rod 1 35 and the threaded rod 2 36 are driven to rotate in opposite directions.

[0035] The self-locking motor 31 is existing technology, and its structural principle will not be detailed here. Specifically, the self-locking motor 31 can be a self-locking geared motor, such as the JGY-370 worm gear reducer motor. This motor is connected to the workshop's three-phase industrial power supply via a main circuit. The motor's start, stop, and direction are managed by a control circuit. The core of this circuit is a forward and reverse magnetic starter (usually composed of two contactors with electrical interlocking function). The operator issues commands via a simple button station; when the forward start button is pressed, the control circuit is activated, driving the geared motor to rotate forward. Power is transmitted via the output shaft to the large bevel gear 32, transmission group one 33, and transmission group two 34, which in turn drive threaded rod one 35 and threaded rod two 36 to begin rotating in the opposite direction, causing the grille to tilt to one side. Due to the inherent self-locking characteristics of the worm gear mechanism, when the motor stops, the transmission chain can be reliably locked, allowing the grille to be stably suspended at any tilt angle. After the painting on this side is completed, press the reverse start button, and the self-locking motor 31 will run in reverse, driving the grille to tilt to the other side, thereby achieving the painting of the bottom of the grille and the inner wall of the groove.

[0036] The implementation principle of the automotive grille processing device in this application embodiment is as follows: First, the operator places the automotive grille on two support rods 4. The two support rods 4 must be stably placed with the grille, and the center of the support rods 4 corresponds to the center of the grille to avoid the grille tilting. The auxiliary mechanism 3 drives the two support rods 4 to move in opposite directions, so that the grille is tilted during the painting process. The spray gun can be aimed at the bottom and inner area of ​​the unfolded grille to improve the spray coverage and reduce the generation of dead corners. During the tilting process, the arc end of a limiting rod 5 hooks in the opposite direction, like a safety hook, to lock the grille from the inside and prevent the grille from falling off.

[0037] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
