Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and in particular to a polishing equipment for automotive interior parts. Background Technology

[0002] Interior trim is the decorative parts covering the interior of a car. It is not only aesthetically pleasing but also serves various functions. Based on the product form, automotive interior trim can be divided into hard interior trim and soft interior trim. Hard interior trim mainly uses injection molding as the core process, and the main products include the main and auxiliary instrument panels, door panels, pillar guards, and steering wheels. Soft interior trim mainly includes sun visors, headliners, and main carpets.

[0003] Publication (Announcement) No.: CN114932481A discloses a pre-treatment device for injection molding of an automotive steering wheel frame, including a chassis. Two fixed plates are connected to the top of the chassis via a rotating mechanism. Two clamping plates are connected between the two fixed plates via a driving mechanism. A fixed plate is connected to the top of the chassis via a connecting column. The fixed plate has a circular opening through which both clamping plates pass. A mounting plate is connected to the top of the fixed plate via a sliding rod. The bottom of the mounting plate is connected to the mounting plate via a telescopic mechanism. In this invention, the two clamping plates expand outwards to tighten and fix the steering wheel frame. The clamping plates rotate the steering wheel frame, which can shake off residual cooling water on its outer surface during machining, thereby ensuring the cleanliness and dryness of the steering wheel frame's outer surface. Furthermore, during rotation, contact with the grinding sleeve installed on the inner ring of the fixed ring can grind away impurities such as slag and flash that affect the smoothness of the steering wheel frame.

[0004] After injection molding, existing steering wheels require a series of processes including edge beveling, fine sanding (only on the steering wheel rim to facilitate subsequent overlay), resin coating, and overlay. The precision of sanding the inner and outer rims of the steering wheel rim determines the quality of the finished product after overlay. However, due to the special shape of the steering wheel and the obstruction at the connection between the rim and spokes, as shown in the attached... Figure 11 As shown; therefore, the market generally uses manual polishing of the inner ring of the steering wheel hub. However, manual polishing is inefficient and cannot control the uniformity of polishing, which will affect the quality of the finished product. The method of polishing the inner ring of the steering wheel in the comparative document cannot bypass the connection between the steering wheel hub and the spokes. It will impact and polish the connection between the steering wheel hub and the spokes together, which will reduce the quality of the finished steering wheel and its function needs to be improved. Summary of the Invention

[0005] This invention discloses an automotive interior parts polishing device, which aims to solve the technical problem that the efficiency of existing steering wheel fine polishing equipment and methods needs to be improved.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A grinding device for automotive interior parts includes a machine base, a steering wheel placed on top of the machine base, a quick-connect mechanism provided on top of the machine base, and the steering wheel engaging and fixed above the quick-connect mechanism.

[0008] Two clamping mechanisms are symmetrically arranged on the top side of the machine tool;

[0009] One of the clamping mechanisms is equipped with a polishing mechanism, and the other clamping mechanism is equipped with a coating mechanism.

[0010] A cleaning mechanism is also provided on the side of the clamping mechanism where the grinding mechanism is provided.

[0011] The quick-connect mechanism and the clamping mechanism work together to fix the steering wheel. The quick-connect mechanism drives the steering wheel to rotate, so that it is successively polished by the polishing mechanism inside the clamping mechanism, desiccant removed by the cleaning mechanism on the side of the clamping mechanism, and grease applied by the coating mechanism inside another clamping mechanism. During the grease application, polishing and cleaning process, it can automatically pass over the connection between the steering wheel hub and the spokes, increasing the precision of the processing.

[0012] By incorporating a clamping mechanism, the rotation of the steering wheel causes the clamping mechanism to carry the grinding, cleaning, and coating mechanisms, which move relative to the steering wheel. This allows for the sequential fine grinding of the steering wheel hub, the blowing away of grinding debris, and the application of resin. Furthermore, the clamping mechanism can automatically pass over the connection between the steering wheel hub and the spokes, ensuring the continuity of steering wheel processing and significantly improving work efficiency.

[0013] In a preferred embodiment, the quick-connect mechanism includes a base rotatably mounted on the top of the machine tool, a rotating pivot fixed in the middle of the base, two sets of positioning plates symmetrically arranged on both sides of the base, and the steering wheel engaging and fixed between the rotating pivot and the positioning plates.

[0014] By incorporating a rotating pivot that engages with an existing steering wheel, the additional positioning plate structure assists the user in installing the steering wheel, thereby improving the ease of use of this device.

[0015] In a preferred embodiment, the clamping mechanism includes two bidirectional electric pneumatic rods symmetrically fixed to the top side of the machine tool. Each bidirectional electric pneumatic rod has an integrated shell fixed at its top and bottom. Each integrated shell has a first clamping part and a second clamping part distributed inside. Each integrated shell also has a connecting rod vertically fixed inside. The bottom of the connecting rod is slidably distributed inside the second clamping part. A telescopic block is installed on the bottom side of the connecting rod. A push rod is horizontally fixed on the bottom side of the first clamping part. A limit groove is horizontally formed on the bottom side of the second clamping part. The push rod and the telescopic block are both distributed inside the limit groove.

[0016] By incorporating two sets of clamping parts driven by a bidirectional electric pneumatic rod, the second clamping part carries the grinding and coating mechanisms, moving relative to the steering wheel to sequentially perform fine grinding and resin coating operations on the steering wheel hub. The first clamping part first contacts the connection between the steering wheel hub and spokes to release its self-locking mechanism, allowing the second clamping part to disengage from the connecting rod and pass over the connection. After passing over, it reconnects with the connecting rod, ensuring the stability of the equipment during grinding, improving the efficiency of existing steering wheel grinding, and enhancing the overall reliability of the equipment.

[0017] In a preferred embodiment, the polishing mechanism includes abrasive plates symmetrically distributed inside a set of second clamping portions, with a clamping plate fixed to the side end of each abrasive plate, and the clamping plate being inserted into the interior of the second clamping portion.

[0018] By incorporating a quick-release frosting plate structure, the efficiency of polishing the steering wheel is ensured, while also improving the ease with which the user can replace the frosting plate.

[0019] In a preferred embodiment, the applicator includes a number of balls rotatably mounted inside another set of second clamping parts. The number of balls is several and they are divided into several groups and evenly distributed in the horizontal direction. Each of the other set of second clamping parts has a liquid flow channel inside. The balls located inside the same second clamping part are connected to the inside of the liquid flow channel. A glue bottle is fixed on the top of the integrated shell. A liquid flow pipe is connected through the glue bottle and the liquid flow channel.

[0020] By incorporating a coating mechanism driven by ball bearings, the rotation of the ball bearings carries the resin from the flow tank and coats it onto the steering wheel hub. This ensures the normal operation of the coating process while reducing unnecessary waste of resin and improving the efficiency of equipment operation.

[0021] In a preferred embodiment, the cleaning mechanism includes air vents symmetrically fixed to the side ends of a set of integrated housings, a pump fixed to the top side end of the machine base, and a three-way air pipe connecting the pump and the two air vents.

[0022] By incorporating an air exhaust structure connected to the pump, the pump and air exhaust system remove the fine debris generated during grinding in a timely manner, thereby preventing the debris from affecting the subsequent resin coating process and improving the overall performance of the equipment.

[0023] As can be seen from the above, the automotive interior parts polishing equipment provided by this invention has the following improvements and advantages compared with the prior art:

[0024] Firstly, by setting up a clamping part that carries a sanding plate, an air vent, and a resin-filled ball bearing, which move relative to the steering wheel, the steering wheel hub is finely sanded, the sanding debris is blown away, and resin is applied in sequence. Moreover, each set of clamping parts can pass over the connection between the steering wheel hub and the spokes, thus ensuring the continuity of steering wheel processing and greatly improving the efficiency of existing steering wheel fine sanding processes.

[0025] Secondly, a first clamping part and a second clamping part are respectively provided. The second clamping part and the connecting rod are in a fixed state and contact the steering wheel by compression. The self-locking of the second clamping part is released by the vertical movement of the first clamping part, so that the second clamping part can disengage from the connection with the connecting rod and pass over the connection between the steering wheel hub and the spokes. After passing over, it can re-establish the connection with the connecting rod, thereby ensuring the stability of this equipment during grinding, improving the grinding efficiency of existing steering wheels, and improving the completeness of the operation of this equipment.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] The automotive interior parts polishing equipment disclosed in this invention is mainly used in the fine polishing of steering wheels.

[0040] Reference Figures 1 to 11 A grinding device for automotive interior parts includes a machine base 1, a steering wheel 2 placed on top of the machine base 1, and a quick-connect mechanism 3 provided on the top of the machine base 1, with the steering wheel 2 engaged and fixed above the quick-connect mechanism 3.

[0041] Two clamping mechanisms 4 are symmetrically arranged on the top side of the machine base 1;

[0042] A grinding mechanism 5 is installed inside one clamping mechanism 4, and a coating mechanism 6 is installed inside the other clamping mechanism 4;

[0043] The clamping mechanism 4, which is equipped with a grinding mechanism 5, is also equipped with a cleaning mechanism 7 on its side.

[0044] The quick-connect mechanism 3 and the clamping mechanism 4 work together to fix the steering wheel 2. The quick-connect mechanism 3 drives the steering wheel 2 to rotate, so that it is polished by the polishing mechanism 5 inside the clamping mechanism 4, the cleaning mechanism 7 on the side of the clamping mechanism 4 removes chips, and the coating mechanism 6 inside another clamping mechanism 4 applies grease. During the grease application, polishing and cleaning process, it can automatically pass over the connection between the steering wheel hub and the spokes, increasing the precision of the processing.

[0045] In this embodiment: When the user needs to polish the steering wheel 2, the user first holds the steering wheel 2 and installs it onto the quick-connect mechanism 3. At the same time, a set of clamping mechanisms 4 is activated, causing the polishing mechanism 5 located inside the clamping mechanism 4 to contact the steering wheel 2. Simultaneously, the quick-connect mechanism 3 is activated, causing the quick-connect mechanism 3 to rotate along the inside of the polishing mechanism 5, thereby being polished by the polishing mechanism 5. While the steering wheel 2 is being polished, the cleaning mechanism 7 works to blow away the debris generated during polishing, completing the polishing work. At this time, the user first closes this set of clamping mechanisms 4, causing the polishing mechanism 5 to disengage from the steering wheel 2. Then, another set of clamping mechanisms 4 is activated, causing the coating mechanism 6 located inside the clamping mechanism 4 to contact the steering wheel 2. As the quick-connect mechanism 3 rotates, the coating mechanism 6 will evenly coat the steering wheel 2 with resin, completing all the work.

[0046] In the above scheme, considering the need to quickly fix the steering wheel 2, the specific operation is as follows.

[0047] Reference Figure 3 and Figure 4 In a preferred embodiment, the quick-connect mechanism 3 includes a base 301 rotatably mounted on the top of the machine base 1, a rotating shaft 302 fixed in the middle of the base 301, and two sets of positioning plates 303 symmetrically arranged on both sides of the base 301. The steering wheel 2 is engaged and fixed between the rotating shaft 302 and the positioning plates 303.

[0048] In this embodiment: when the user needs to polish the steering wheel 2, the user needs to hold the steering wheel 2 in his hand and align the steering wheel 2 with the gap between the two sets of positioning plates 303, and then engage the middle part of the steering wheel 2 with the outside of the rotating shaft 302, so that the steering wheel 2 is fixed above the base 301. When the steering wheel 2 needs to be processed, the user starts the electric device built into the machine tool 1, thereby driving the base 301 and the rotating shaft 302 to rotate, and driving the steering wheel 2 to rotate.

[0049] It should be noted that the machine tool 1 is equipped with a power source, such as a motor, that drives the base 301 and the rotating shaft 302 to rotate.

[0050] In the above scheme, considering that the polishing mechanism 5 and the coating mechanism 6 can operate independently and are not obstructed by the connection between the steering wheel 2 hub and spokes, the specific operation is as follows.

[0051] Reference Figures 1 to 9 In a preferred embodiment, the clamping mechanism 4 includes two bidirectional electric pneumatic rods 401 symmetrically fixed to the top side of the machine base 1. Each bidirectional electric pneumatic rod 401 has an integrated shell 402 fixed at its top and bottom. Each integrated shell 402 has a first clamping part 403 and a second clamping part 404 distributed inside. Each integrated shell 402 also has a connecting rod 405 vertically fixed inside. The bottom of the connecting rod 405 is slidably distributed inside the second clamping part 404. A telescopic block 406 is installed at the bottom side of the connecting rod 405. A push rod 407 is horizontally fixed at the bottom side of the first clamping part 403. A limiting groove 408 is horizontally opened at the bottom side of the second clamping part 404. The push rod 407 and the telescopic block 406 are both distributed inside the limiting groove 408.

[0052] In this embodiment: the user activates the bidirectional electric pneumatic strut 401, causing the two output shafts of the bidirectional electric pneumatic strut 401 to retract, thereby driving the two symmetrical integrated housings 402 to move synchronously. This causes the connecting rod 405 located inside the integrated housing 402 to move synchronously, pushing the first clamping part 403 and the second clamping part 404 close to the steering wheel 2, squeezing and clamping the hub of the steering wheel 2. As the quick-connect mechanism 3 rotates the steering wheel 2, when the first clamping part 403 contacts the connection between the hub and the spokes of the steering wheel 2, the side end of the first clamping part 403 will squeeze the connection, thereby moving in the vertical direction. The push rod 407 fixed to the side end of the first clamping part 403 will move synchronously, thereby squeezing the telescopic block 406, causing the telescopic block 406 to move towards the connecting rod 405. Internal contraction causes the telescopic block 406 to disengage from the limiting groove 408. At this time, the connecting rod 405 loses its fixed relationship with the second clamping part 404. As the steering wheel 2 rotates, the second clamping part 404, which is in a free state, comes into contact with the hub and spoke connection of the steering wheel 2, thus enabling vertical movement and "passing over" the hub and spoke connection of the steering wheel 2. After the first clamping part 403 and the second clamping part 404 have passed over the hub and spoke connection of the steering wheel 2, the first clamping part 403 resets, driving the push rod 407 to release the pressure on the telescopic block 406. The popped-out telescopic block 406 re-inserts into the limiting groove 408, thereby causing the second clamping part 404 to reconnect and fix with the connecting rod 405, ensuring the stability during operation.

[0053] It should be noted that a spring 409 is fixedly connected between the inner wall of the first clamping part 403 and the inner wall of the integrated shell 402, and between the second clamping part 404 and the inner wall of the integrated shell 402. When the first clamping part 403 and the second clamping part 404 pass over the connection between the hub and the spokes of the steering wheel 2, the spring 409 provides a pushing force, thereby driving the first clamping part 403 and the second clamping part 404 to reset and move.

[0054] Furthermore, it should be noted that the lower part of the first clamping part 403 and the second clamping part 404 on the same side are both arc-shaped structures. The arc-shaped structures are used to press the connection between the hub and the spokes of the steering wheel 2, thereby better converting the horizontal force into a vertical force to push the first clamping part 403 and the second clamping part 404 to move vertically.

[0055] In the above scheme, considering the need for fine polishing of the hub area of ​​steering wheel 2, the specific operation is as follows.

[0056] Reference Figure 7 In a preferred embodiment, the polishing mechanism 5 includes abrasive plates 501 symmetrically distributed inside a set of second clamping portions 404. A clamping plate 502 is fixed to the side end of the abrasive plate 501, and the clamping plate 502 is inserted into the interior of the second clamping portion 404.

[0057] In this embodiment: when a set of first clamping parts 403 and second clamping parts 404 are close to the steering wheel 2, squeezing and clamping the hub part of the steering wheel 2, the frosted plate 501 located inside the second clamping part 404 will be in close contact with the steering wheel 2. As the steering wheel 2 is driven by the quick-connect mechanism 3 to rotate, the frosted plate 501 and the steering wheel 2 move relative to each other, thereby polishing the hub part of the steering wheel 2. When the user needs to replace the frosted plate 501, he only needs to pull the frosted plate 501 by hand, so that the clamping plate 502 located on the side of the frosted plate 501 can be disengaged from the second clamping part 404.

[0058] It should be noted that a collection box 8 is placed on the bottom side of the machine 1 to collect the debris generated during grinding.

[0059] Furthermore, it should be noted that due to the operating characteristics of this equipment, the area where the hub and spokes of the steering wheel 2 are connected cannot be effectively polished and coated. Therefore, the steering wheel 2 processed by this equipment still needs to be manually repaired and patched.

[0060] In the above scheme, considering the need to continue applying resin to the finely polished steering wheel 2, the specific operation is as follows.

[0061] Reference Figures 1 to 3 , Figures 8 to 9In a preferred embodiment, the applicator 6 includes a ball bearing 601 rotatably mounted inside another set of second clamping parts 404. The ball bearings 601 are numerous and divided into several groups, and are evenly distributed in the horizontal direction. Each of the other set of second clamping parts 404 has a liquid flow groove 602 inside, and the ball bearings 601 inside the same second clamping part 404 and the liquid flow groove 602 are connected. A glue bottle 603 is fixed on the top of the integrated shell 402, and a liquid flow tube 604 is connected through the glue bottle 603 and the liquid flow groove 602.

[0062] In this embodiment: when another set of first clamping parts 403 and second clamping parts 404 are close to the steering wheel 2, squeezing and clamping the hub part of the steering wheel 2, the ball bearing 601 located inside the second clamping part 404 will be in close contact with the steering wheel 2. As the steering wheel 2 is driven by the quick-connect mechanism 3 to rotate, the ball bearing 601 moves relative to the steering wheel 2, thereby bringing the resin inside the glue bottle 603 into the ball bearing 601 through the flow pipe 604 and the flow groove 602, and applying it to the steering wheel 2 as the ball bearing 601 rotates.

[0063] It should be noted that the side ends of the second clamping part 404, which is equipped with ball bearings 601, are all fixed with cotton wipes 605. The cotton wipes 605 are used to further apply resin to the steering wheel 2, making the resin distribution more uniform.

[0064] In the above solution, considering that a large amount of fine debris will be generated after the steering wheel 2 is finely polished and needs to be processed, the specific operation is as follows.

[0065] Reference Figures 1 to 3 , Figure 7 and Figure 9 In a preferred embodiment, the cleaning mechanism 7 includes air outlets 701 symmetrically fixed to the side of a set of integrated housings 402, a pump 702 fixed to the top side of the machine base 1, and a three-way air pipe 703 connecting the pump 702 and the two air outlets 701.

[0066] In this embodiment: while the steering wheel 2 is being polished, the pump 702 starts to work, introducing high-pressure gas into the interior of the two air outlets 701 through the three-way air pipe 703, thereby blowing away the debris adhering to the steering wheel 2.

[0067] Working principle: During use, the user first installs the steering wheel 2 onto the outside of the rotating pivot 302, and simultaneously activates a two-way electric pneumatic strut 401. The two output shafts of the two-way electric pneumatic strut 401 retract, thereby driving the two symmetrical integrated housings 402 to move synchronously. This causes the connecting rods 405 located inside the integrated housings 402 to move synchronously, pushing the first clamping part 403, the second clamping part 404, and the frosted plate 501 to press the hub of the steering wheel 2. As the rotating pivot 302 drives the steering wheel... When the steering wheel 2 is rotated, the abrasive plate 501 polishes the hub area of ​​the steering wheel 2. When the first clamping part 403 contacts the connection between the hub and the spokes of the steering wheel 2, the side end of the first clamping part 403 will press against the connection and move vertically. The push rod 407 fixed to the side end of the first clamping part 403 will move synchronously, thereby pressing the telescopic block 406, causing the telescopic block 406 to retract and disengage from the limiting groove 408. At this time, the connecting rod 405 loses its fixed relationship with the second clamping part 404. As the steering wheel 2 rotates, the second clamping part 404 makes pressing contact with the connection between the steering wheel 2 hub and spokes, causing the abrasive plate 501 to move vertically, "crossing" the connection between the steering wheel 2 hub and spokes. This process is repeated, continuously crossing the connection between the steering wheel 2 hub and spokes, completing the grinding of the steering wheel 2. Simultaneously, the air exhaust 701 works to blow away the grinding debris. After grinding is complete, the bidirectional electric pneumatic rod 401 stops operating, causing the grinding... The sanding plate 501 disengages from the steering wheel 2, and another bidirectional electric pneumatic rod 401 begins to work, repeating the above steps to bring the ball bearings 601 inside the second clamping part 404 into close contact with the steering wheel 2. As the steering wheel 2 rotates, the ball bearings 601 move relative to the steering wheel 2, thereby bringing the resin inside the glue bottle 603 into the ball bearings 601 through the flow pipe 604 and the flow groove 602, and applying it to the steering wheel 2 as the ball bearings 601 rotate, thus completing all the work.

[0068] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
