Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive trim panel technology, and more specifically, to a device for removing burrs from holes in automotive trim panels. Background Technology
[0002] Automotive trim panels refer to decorative panels installed on various parts of a car's interior. Their main function is to enhance the visual appeal and overall quality of the cabin. They are typically made from a variety of materials, such as plastic, wood grain trim, brushed metal, carbon fiber texture, or leather wrapping. The design balances aesthetics and practicality. High-quality trim panels are an important element in enhancing the driving experience and the vehicle's class, combining both aesthetic and functional value.
[0003] Common automotive trim hole burr removal devices can only polish the inner walls of the holes. In practical applications, polishing only the inner walls of the holes cannot completely remove the burrs. The burrs on the inner walls will be transferred to the surface of the trim panel and adhere to it during polishing. This not only affects the assembly, but also causes abnormal noises during the use of the product, ultimately leading to a decline in product quality.
[0004] In summary, to ensure product quality, it is necessary to address the issue of burrs from the holes in the decorative panels transferring and adhering to the surface, so that the burrs at the edges of the holes can be completely removed. Utility Model Content
[0005] The present invention provides a device for removing burrs from holes in automotive trim panels. The problem to be solved is that burrs on the inner wall are transferred to the surface of the trim panel and adhere to it when the panel is being polished. This not only affects the assembly, but also causes abnormal noises during the use of the product.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for removing burrs from holes in automotive trim panels, comprising a handheld housing, an electronic control mechanism on the handheld housing, a drive mechanism on the handheld housing, a mounting plate on the drive mechanism, a partition plate on the surface of the mounting plate, two sets of telescopic rods symmetrically mounted on the surface of the partition plate, an elastic plate mounted on the telescopic end of the telescopic rods, multiple grinding grooves on the side of the elastic plate away from the telescopic rods, and two sets of springs symmetrically mounted on the surface of the partition plate, with the end of the spring away from the partition plate connected to the elastic plate.
[0007] In a preferred embodiment, the electronic control mechanism is used to provide electrical power and control the start and stop of the drive mechanism. The electronic control mechanism includes a power supply component and a control component. The power supply component is used to provide electrical power to the electronic components, and the control component is used to control the start and stop of the drive mechanism.
[0008] In a preferred embodiment, the power supply assembly includes a battery installed inside the handheld housing and four card slots installed inside the handheld housing.
[0009] In a preferred embodiment, the control components are surface-mounted to a control box inside the handheld housing and a trigger mounted on the surface of the control box.
[0010] In a preferred embodiment, the output end of the drive mechanism is connected to the mounting plate. The drive mechanism is used to control the rotational movement of the elastic plate. The drive mechanism includes a power component and a linkage component. The output end of the power component is connected to the linkage component, and the power component is used to control the rotational movement of the linkage component. The output end of the linkage component is connected to the mounting plate, and the linkage component is used to control the rotational movement of the mounting plate.
[0011] In a preferred embodiment, the power assembly includes a fixed frame installed inside the handheld housing, a motor installed inside the fixed frame, and a balance wheel installed at the motor output end, the motor being used to control the rotational movement of the balance wheel.
[0012] In a preferred embodiment, the linkage component includes a limiting frame installed inside the handheld housing and an output rod installed on the surface of the balance wheel. The balance wheel is rotatably connected to the limiting frame, and the end of the output rod away from the balance wheel is fixedly connected to the mounting plate.
[0013] In a preferred embodiment, an insert triangle is mounted on the end of the elastic plate away from the handheld housing, and a polymer grip is mounted on the end of the elastic plate near the handheld housing.
[0014] The beneficial effects of this utility model are as follows:
[0015] This invention utilizes a radially adaptive structure formed by an elastic plate, a telescopic rod, and a spring. This structure allows the grinding groove to closely fit the walls of holes with different diameters. Combined with a rotating drive linkage structure, the burrs on the inner wall and outer edge of the hole are cut simultaneously during rotation, preventing burrs on the inner wall from rolling out and adhering during grinding. Ultimately, this achieves simultaneous cleaning of burrs on the inner and outer edges of the hole, improving the assembly and product quality of automotive trim panels. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0023] Refer to the instruction manual appendix Figures 1 to 5 A device for removing burrs from holes in automotive trim panels includes a handheld housing 1, an electronic control mechanism on the handheld housing 1, a drive mechanism on the handheld housing 1, a mounting plate 11 on the drive mechanism, a partition plate 12 mounted on the surface of the mounting plate 11, two sets of telescopic rods 13 symmetrically mounted on the surface of the partition plate 12, an elastic plate 14 mounted on the telescopic end of the telescopic rods 13, a plurality of grinding grooves 15 opened on the side of the elastic plate 14 away from the telescopic rods 13, and two sets of springs 16 symmetrically mounted on the surface of the partition plate 12, with the end of the spring 16 away from the partition plate 12 connected to the elastic plate 14.
[0024] It should be noted that the two sets of symmetrically arranged telescopic rods 13 work together with the springs 16 to enable the elastic plate 14 to have radial elastic telescopic function. When inserted into holes of different diameters, the elastic plate 14 can adaptively contract or expand to ensure that the grinding groove 15 is always in close contact with the hole wall.
[0025] It is worth noting that the grinding groove 15 is opened on the outer side of the elastic plate 14, so that the inner wall of the hole and the outer surface of the edge of the hole can be ground at the same time, preventing the burrs on the inner wall from rolling out and adhering during grinding.
[0026] Refer to the instruction manual appendix Figures 2 to 3 The electronic control mechanism is used to provide electrical energy and control the start and stop of the drive mechanism. The electronic control mechanism includes a power supply component and a control component. The power supply component is used to provide electrical energy to the electronic components, and the control component is used to control the start and stop of the drive mechanism.
[0027] It should be noted that the electronic control mechanism adopts a modular design, with the power supply component powered independently, and the control component connected to the motor 312 of the drive mechanism via signal lines to achieve precise start and stop control.
[0028] Refer to the instruction manual appendix Figures 2 to 3The power supply assembly includes a battery 211 installed inside the handheld housing 1 and four slot plates 212 installed inside the handheld housing 1.
[0029] It should be noted that the four locking plates 212 are symmetrically distributed around the control box 221, and the control box 221 is locked by an elastic buckle structure to prevent poor contact caused by equipment vibration.
[0030] Refer to the instruction manual appendix Figures 2 to 3 The control components are a control box 221 mounted inside the handheld housing 1 and a trigger 222 mounted on the surface of the control box 221.
[0031] It should be noted that the trigger 222 is triggered by a micro switch circuit in the control box 221, and its curved surface conforms to the finger grip posture, which is ergonomic.
[0032] Refer to the instruction manual appendix Figures 3 to 4 The output end of the drive mechanism is connected to the mounting plate 11. The drive mechanism is used to control the rotational movement of the elastic plate 14. The drive mechanism includes a power component and a linkage component. The output end of the power component is connected to the linkage component. The power component is used to control the rotational movement of the linkage component. The output end of the linkage component is connected to the mounting plate 11. The linkage component is used to control the rotational movement of the mounting plate 11.
[0033] It should be noted that the power component converts the high-speed rotation of the motor 312 into a stable torque through the balance wheel 313, and then transmits it to the mounting plate 11 through the linkage component, so as to avoid high-frequency vibration from affecting the grinding accuracy.
[0034] It is worth noting that the linkage component and the power component adopt an axial direct connection structure to reduce transmission loss and ensure the stable rotation speed of the elastic plate 14.
[0035] Refer to the instruction manual appendix Figures 3 to 4 The power assembly includes a fixed frame 311 installed inside the handheld housing 1, a motor 312 installed inside the fixed frame 311, and a balance wheel 313 installed at the output end of the motor 312. The motor 312 is used to control the rotation of the balance wheel 313.
[0036] It should be noted that the fixed frame 311 has an embedded shock-absorbing rubber layer, which effectively absorbs the axial movement of the motor 312 during operation, and the balance wheel 313 is a metal counterweight wheel, which enhances the stability of rotational inertia.
[0037] Refer to the instruction manual appendix Figures 3 to 4 The linkage component includes a limiting frame 321 installed inside the handheld housing 1 and an output rod 322 installed on the surface of the balance wheel 313. The balance wheel 313 is rotatably connected to the limiting frame 321, and the end of the output rod 322 away from the balance wheel 313 is fixedly connected to the mounting plate 11.
[0038] It should be noted that the output rod 322 is coaxially fixed with the central axis of the mounting plate 11 to ensure that the elastic plate 14 is subjected to uniform force during rotation and to avoid uneven wear.
[0039] Refer to the instruction manual appendix Figures 1 to 5 An insert triangle plate 17 is installed at the end of the elastic plate 14 away from the hand-held housing 1, and a polymer grip 18 is installed at the end of the elastic plate 14 near the hand-held housing 1.
[0040] It should be noted that the insertion triangle 17 is a rigid plastic cone, and its pointed design facilitates the precise insertion of the guide device into the hole. The aggregate grip 18 provides a pressure fulcrum for pushing the elastic plate 14.
[0041] Working principle: Hold the outer casing 1 and apply a forward thrust, causing the insertion triangle 17 located at the far end of the elastic plate 14 to be inserted first into the hole to be processed in the automotive trim panel, serving as a guide and positioning function. With continuous pushing, the side of the elastic plate 14 contacts the hole wall. Under the reaction force of the hole wall, the elastic plate 14 drives the telescopic end of the telescopic rod 13 to retract towards the partition plate 12, while compressing the spring 16, until the grinding groove 15 is aligned with the inner wall of the hole. At this time, under the continuous elastic force of the spring 16, the inner wall of the hole is inserted into the interior of the grinding groove 15. Then, press the trigger 222 to trigger the control box 221, start the electronic control mechanism. The battery 211 in the electronic control mechanism supplies power to the motor 312. The motor 312 starts to rotate and drives the balance wheel 313 at its output end to rotate. The balance wheel 313 rotates stably within the limit frame 321, driving the fixed to it. The output rod 322 on the surface rotates synchronously, driving the mounting plate 11 fixedly connected to it to rotate, which in turn drives the partition plate 12 fixed on the mounting plate 11, as well as the two sets of symmetrically installed telescopic rods 13, elastic plates 14 and springs 16 to rotate as a whole. During the rotation, the grinding groove 15 opened on the outer side of the elastic plate 14 grinds and cuts the inner wall of the hole and the outer surface of the hole edge. Because the elastic plate 14 has radial elasticity under the synergistic action of the spring 16 and the telescopic rod 13, it can adapt to holes of different diameters and always maintain the effective contact pressure between the grinding groove 15 and the inner and outer edges of the hole wall, ensuring that the burrs on the inner wall can be completely removed during rotational grinding and preventing them from being squeezed outward and rolled onto the surface of the decorative panel during the grinding process. At the same time, the burrs on the outer edge of the hole are also removed, ultimately achieving the complete removal of burrs on the edge of the hole.
[0042] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
