Description

Technical Field

[0001] This invention relates to the field of sheet metal polishing technology, specifically a polishing device for automotive center console covers after molding. Background Technology

[0002] The car's central control unit is where you control the car's air conditioning, audio system, and other comfort and entertainment features. It also includes the central console, which contains various vehicle controllers such as the audio control panel.

[0003] With the rapid advancements in automotive technology, car center consoles are also quietly evolving. The shift from traditional button operation to a fully touch-sensitive interface is undoubtedly a significant leap, representing technological progress and subtly elevating the overall quality.

[0004] A fully touch-screen center console refers to a car's center console that no longer uses traditional physical operation designs such as buttons and knobs, but instead adopts a capacitive touch screen, just like a mobile phone screen, which can be operated by lightly touching, pressing or sliding.

[0005] Most center console covers are installed onto the center console using clips, and during use, they primarily serve to protect and isolate the center console. When molding car center console panels using molds, their inner and outer surfaces are fitted to the inner wall of the mold. After degreasing, removing dust, and removing water from the inner wall of the mold, the quality of the molded panel can be ensured. However, burrs often appear at the mold seams, so they need to be polished.

[0006] Patent document CN213225521U discloses a grinding device for automobile cover plates. This device uses a motor to control a screw and a sleeve. Rotating the screw adjusts the horizontal position of the motor. The ends of the suspension rod and support rod are movably connected to the inner walls of the lower and upper frames, facilitating left and right movement. The motor is activated by an external power source and switch, driving the main shaft to rotate. The main shaft then drives the linkage shaft, which in turn rotates the grinding mechanism. The mounting plate and grinding disc rotate synchronously, and can be compressed or reset under pressure. This device effectively grinds concave and curved surfaces on automobile cover plates, achieving thorough grinding with excellent results. It reduces grinding dead spots, avoids tedious manual operation, and increases grinding efficiency, meeting the needs of large-scale automobile cover plate production.

[0007] However, in the process of implementing the above technical solution, the following technical problems were found: Existing grinding devices for car covers utilize tension springs and springs in conjunction with the grinding mechanism to grind concave and curved surfaces on the car cover. In practical applications, they are prone to encountering areas with large protrusions or depressions, making it difficult for the grinding mechanism to rotate normally, resulting in significant limitations in grinding performance. Summary of the Invention

[0008] To overcome the shortcomings of existing grinding devices for automotive cover panels, which are prone to encountering areas with large protrusions or depressions, making it difficult for the grinding mechanism to rotate normally and resulting in high grinding limitations, this invention provides a grinding device for automotive center console cover panels after forming. By setting a control structure outside the grinding structure, an electric push rod on the control structure controls a second sliding sleeve to drive a first long rod. The angle between the first and second long rods is adjusted. When the power part transmits power to the grinding structure through the clamping and fixing head, a universal joint can be connected between the second long rod and the universal joint, so that the rotating second long rod transmits power to the tilted first long rod, ultimately meeting the actual grinding requirements without needing to control the orientation and angle of the power part.

[0009] The technical solution adopted by the embodiments of the present invention to solve its technical problem is as follows: A grinding device for a molded automotive center console cover includes a grinding part applied to the device. The grinding part includes a clamping and fixing head, a grinding structure, and a control structure. The grinding structure is disposed at one end of the clamping and fixing head. The control structure is located outside the grinding structure; The grinding structure includes a second long rod, one end of which is fitted with a universal joint, and one end of which is fitted with a first long rod. One end of the first long rod is machined with a prism rod, and the prism rod is externally pin-connected to a support inner sleeve. The support inner sleeve is externally sleeve-connected to a grinding ring. The control structure controls the angle between the first and second long rods, and the universal joint connects between the first and second long rods. The second long rod is rotated by a clamping and fixing head connected to the power unit.

[0010] In one possible implementation, the outer wall of the supporting inner sleeve is machined with a plurality of anti-slip strips, which are equally spaced around the center of the supporting inner sleeve, with one side of each anti-slip strip embedded in the inner wall of the polishing ring.

[0011] In one possible implementation, the anti-slip strip has an obtuse triangular cross section, and the tips of the plurality of anti-slip strips are all oriented in the same direction as the second long rod rotates under the influence of the clamping and fixing head.

[0012] In one possible implementation, one end of the prism bar is machined with a threaded rod, and one end of the threaded rod is threadedly connected to a nut to restrict the inner support sleeve from sliding along its axial direction from the outside of the prism bar.

[0013] In one possible implementation, the clamping head includes a clamping rod, one end of which is machined with an adapter post. A limiting protrusion is formed on the surface of one end of the adapter post. One end of the second long rod is machined with an adapter, the surface of which is machined with a limiting groove. The limiting protrusion is adapted to the interior of the limiting groove. The adapter post and the adapter are fixed by a bolt that passes through the interior of the clamping rod and the adapter post and is threadedly connected to the adapter.

[0014] In one possible implementation, the adapter has an isosceles trapezoidal cross-section, the diameter of the adapter post is the same as the diameter of the top end face circle of the adapter, the bottom end face circle of the adapter is the same as the diameter of the second long rod, the diameter of the adapter post is larger than the diameter of the second long rod, and the diameter of the adapter post is the same as the diameter of the grinding ring.

[0015] In one possible implementation, the control structure includes an adapting sleeve, one end of which has an erecting arm machined on its outer surface. One end of the erecting arm is hinged to an electric push rod, and one end of the electric push rod is hinged to a second sliding sleeve. The second sliding sleeve is fitted over the outside of the first long rod and slides outside of it.

[0016] In one possible implementation, the adapting sleeve includes a protective sleeve, and a first sliding sleeve is provided on the inner side of the protective sleeve. Two springs are provided between the outer walls of both ends of the first sliding sleeve and the inner walls of both ends of the protective sleeve.

[0017] In one possible implementation, the spring is internally connected to a limiting slide rod, and two limiting slide rods at one end of the first slide sleeve are symmetrically arranged on both sides of the axis of the first slide sleeve, and the two limiting slide rods are coaxially arranged. One end of the limiting slide rod is pinned to the inside of the first slide sleeve, and the protective sleeve is slidably connected to the outside of the limiting slide rod.

[0018] The beneficial effects of this invention are as follows: Firstly, in this solution, a control structure is set outside the grinding structure, so that the electric push rod on the control structure controls the second sliding sleeve to drive the first long rod to move, and adjusts the angle between the first long rod and the second long rod. When the power part transmits power to the grinding structure through the clamping and fixing head, a universal joint can be connected between the second long rod and the universal joint, so that the rotating second long rod transmits power to the tilted first long rod, ultimately meeting the actual grinding requirements without the need to control the orientation and angle of the power part. Secondly, in this solution, by setting the diameter of the second long rod to be smaller than that of the grinding ring, the second long rod does not contact the grinding ring when it grinds the surface of the cover plate. At the same time, an appropriate sleeve is set on the outside of the second long rod. As the grinding ring continuously grinds the surface of the cover plate, the protective sleeve comes into contact with the non-grinding area. The protective sleeve compresses the spring between the inner wall of the protective sleeve and the outer wall of the limiting slide rod, which can ensure that the grinding ring grinds a fixed thickness on the surface of the cover plate and forms good protection to avoid damage to the non-grinding area of ​​the cover plate.

Detailed Implementation

[0021] The technical solutions in these embodiments of the invention address the problems described in the background section, and the overall approach is as follows: Example: This embodiment describes the specific structure of a grinding device for automotive center console cover panels after molding. See details below. Figures 1-6 As shown, the device includes a grinding section, which includes a clamping head 1, a grinding structure 3 disposed at one end of the clamping head 1, and a control structure 2 disposed outside the grinding structure 3. The grinding structure 3 includes a second long rod 305, one end of which is assembled with a universal joint 301, one end of which is assembled with a first long rod 302, one end of which is machined with a prism rod 306, the prism rod 306 is pin-connected to a support inner sleeve 308, and the support inner sleeve 308 is sleeve-connected to a grinding ring 303. In this way, by pinning the inner support sleeve 308 and the prism rod 306 together, when the first long rod 302 rotates, the inner support sleeve 308 can be driven to rotate through the prism rod 306. The grinding ring 303 is sleeved on the outside of the inner support sleeve 308, which can further drive the grinding ring 303 to rotate. Secondly, the clamping and fixing head 1 includes a clamping rod 101, one end of which is machined with an adapter post 102, and one end of the second long rod 305 is machined with an adapter 304. After connecting and fixing one end of the adapter 304 to the adapter post 102, one end of the clamping and fixing head 1 is fixed to the power part, and the power part transmits power to control the clamping and fixing head 1 to rotate, thereby driving the grinding structure 3 to rotate as a whole, so that the grinding ring 303 outside the supporting inner sleeve 308 can perform grinding work on the car center console cover. Meanwhile, in order to facilitate the connection and fixation of the clamping head 1 to the grinding structure 3, and to ensure that the clamping head 1, which is fixed to the power unit, stably transmits power to the grinding structure 3, such as... Figure 3 and Figure 4 As shown, a limiting protrusion 103 is formed on the surface of one end of the adapter post 102, and a limiting groove 4 is machined on the surface of the adapter 304. By adapting the limiting protrusion 103 to the inside of the limiting groove 4, after the bolt passes through the inside of the clamping rod 101 and the adapter post 102 and is threadedly connected to the adapter 304, the adapter post 102 and the adapter 304 can be fixed and the relative rotation between the adapter post 102 and the adapter 304 can be prevented. Furthermore, to prevent the first long rod 302 from driving the inner support sleeve 308 to rotate via the prism rod 306, causing the grinding ring 303 to slip against the outside of the inner support sleeve 308 when grinding the target area, thus affecting the grinding effect, such as... Figure 2 and Figure 3 As shown, the outer wall of the inner support sleeve 308 is machined with multiple anti-slip strips 309. The multiple anti-slip strips 309 are evenly spaced around the center of the inner support sleeve 308. After the grinding ring 303 is fitted onto the outside of the inner support sleeve 308, one side of the anti-slip strip 309 is embedded in the inner wall of the grinding ring 303, which can ensure the friction between the outer wall of the inner support sleeve 308 and the inner wall of the grinding ring 303, thereby achieving the anti-slip effect. Meanwhile, in order to further improve the friction between the inner support sleeve 308 and the grinding ring 303, the anti-slip strip 309 is set as an anti-slip strip with an obtuse triangular cross section, ensuring that the tip direction of multiple anti-slip strips 309 is the same as the direction of rotation of the second long rod 305 driven by the clamping and fixing head 1 (generally considered to be clockwise). The friction between the tip and the inner wall of the grinding ring 303 can be used to ensure that the grinding ring 303 is fixed to the outside of the inner support sleeve 308 when the cover plate is being ground in a controlled manner. Furthermore, to prevent the inner support sleeve 308 from detaching from the outside of the prism rod 306, such as... Figure 3 As shown (this state is the exploded state), one end of the prism rod 306 is machined with a threaded rod 307. By pinning the prism rod 306 to the inside of the support inner sleeve 308, one end of the prism rod 306 drives the threaded rod 307 to pass through the inside of the support inner sleeve 308. After the connecting nut of the threaded rod 307, the support inner sleeve 308 can be restricted from sliding along its axial direction from the outside of the prism rod 306, thereby achieving the effect of assembling and fixing the support inner sleeve 308 to the outside of the prism rod 306. In some examples, the cross-section of the adapter 304 is an isosceles trapezoid, the diameter of the adapter post 102 is the same as the diameter of the top end face circle of the adapter 304, and the bottom end face circle of the adapter 304 is the same as the diameter of the second long rod 305. By making the diameter of the adapter post 102 larger than the diameter of the second long rod 305, and the diameter of the adapter post 102 being the same as the diameter of the grinding ring 303, it is ensured that the diameters of the second long rod 305 and the first long rod 302 on the grinding structure 3 are smaller than the diameters of the adapter post 102 and the support inner sleeve 308 (e.g., Figure 3 As shown, when the grinding ring 303 grinds the cover plate, a gap can be left between the second long rod 305 and the surface of the cover plate to avoid wear on the non-grinding area; like Figure 1 and Figure 5 As shown, the control structure 2 includes an adapting sleeve 201. A mounting arm 202 is machined on the outer surface of one end of the adapting sleeve 201. An electric push rod 203 is hinged to one end of the mounting arm 202. A second sliding sleeve 204 is hinged to one end of the electric push rod 203. The second sliding sleeve 204 is sleeved on the outside of the first long rod 302. When the electric push rod 203 controls the second sliding sleeve 204 to drive the first long rod 302 to move and adjust the angle between the first long rod 302 and the second long rod 305, the second sliding sleeve 204 slides outside the first long rod 302 to automatically adjust the length. This ensures that when the second long rod 305 rotates, the first long rod 302 can be driven to rotate through the universal joint 301, which in turn causes the prism rod 306 to drive the inner support sleeve 308 to rotate. Secondly, such as Figure 5 and Figure 6As shown, the adapting sleeve 201 includes a protective sleeve 2011. A first sliding sleeve 2012 is provided on the inner side of the protective sleeve 2011. Two springs 2014 are provided between the outer walls of both ends of the first sliding sleeve 2012 and the inner walls of both ends of the protective sleeve 2011. The springs 2014 are internally connected to limit sliding rods 2013. By symmetrically arranging the two limit sliding rods 2013 at one end of the first sliding sleeve 2012 on both sides of the axis of the first sliding sleeve 2012, the two limit sliding rods 2013 are coaxially arranged. When one end of the limit sliding rod 2013 is pinned to the inside of the first sliding sleeve 2012, the protective sleeve 2011 can be restricted to move up and down outside the first sliding sleeve 2012. When the grinding ring 303 grinds the surface of the cover plate, the protective sleeve 2011 contacts the non-grinding area, while the second long rod 305 can continuously rotate inside the first sliding sleeve 2012. Meanwhile, by allowing the protective sleeve 2011 to slide outside the limiting slide bar 2013, when the protective sleeve 2011 contacts the non-grinding area of ​​the cover plate surface, the protective sleeve 2011 can be eccentrically positioned outside the first slide sleeve 2012, compressing the spring 2014 outside the limiting slide bar 2013, so as to avoid the grinding ring 303 being restricted by the contact between the protective sleeve 2011 and the cover plate surface, which would prevent the grinding ring 303 from grinding a fixed thickness on the cover plate surface.

[0022] Specifically, when using this grinding device to grind the shaped car center console cover: First, the bolt is passed through the inside of the clamping rod 101 and the adapter post 102 and threaded into the adapter 304, so that the limiting protrusion 103 on one end surface of the adapter post 102 is located inside the limiting groove 4. After the adapter post 102 and the adapter 304 are fixed, one end of the clamping rod 101 is clamped and fixed by the power part. Then, the power unit controls the clamping rod 101 to drive the adapter post 102 to rotate. With the help of the limiting protrusion 103 and the limiting groove 4, the adapter 304 and the second long rod 305 are driven to rotate. Since the universal joint 301 is connected between the second long rod 305 and the first long rod 302, it can support the rotation of the second long rod 305 to drive the support inner sleeve 308 outside the prism rod 306 to rotate. Next, by means of multiple anti-slip strips 309 with obtuse triangular cross sections machined on the outer wall of the inner support sleeve 308, when the grinding ring 303 is fitted onto the outer side of the inner support sleeve 308, the grinding ring 303 is restricted from moving in the opposite direction of the rotation of the first long rod 302 outside the inner support sleeve 308, i.e., slipping. This helps to avoid energy loss between the grinding ring 303 and the inner support sleeve 308 due to slipping. During the polishing process, the rotating polishing ring 303 continuously polishes the cover plate surface. With the protection of one end of the control structure 2 outside the second long rod 305, the non-polished area of ​​the cover plate can be prevented from being worn. Furthermore, by contacting the protective sleeve 2011 with the non-polished area, and while the second long rod 305 can continuously rotate inside the first sliding sleeve 2012, the protective sleeve 2011 slides outside the limiting slide rod 2013, compressing the spring 2014 between the inner wall of the protective sleeve 2011 and the outer wall of the limiting slide rod 2013. This ensures that the polishing ring 303 grinds a fixed thickness on the cover plate surface, without being restricted by the contact between the protective sleeve 2011 and the cover plate surface. Meanwhile, when it is necessary to insert the grinding ring 303 into the recessed area at a fixed grinding angle, the electric push rod 203 is activated, which controls the second sliding sleeve 204 to drive the first long rod 302 to move. The angle between the first long rod 302 and the second long rod 305 is adjusted so that the rotating second long rod 305 can transmit power to the tilted first long rod 302 to meet the actual grinding needs, which is highly efficient.

[0023] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
