Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, specifically to a polishing device for electric vehicle dashboards. Background Technology

[0002] In the electric vehicle manufacturing industry, the dashboard, as a crucial interior component, directly impacts the overall quality and aesthetics of the vehicle. Traditional dashboard polishing primarily relies on manual operation, with workers using hand-held polishing tools. This method has several drawbacks. Firstly, manual polishing struggles to ensure uniformity. Inconsistencies in pressure, angle, and speed among workers lead to inconsistent polishing results, potentially causing over- or under-polishing in certain areas, thus affecting product yield. Secondly, manual polishing is inefficient, failing to meet production schedules in large-scale production, increasing both production and time costs. Furthermore, the polishing process generates significant dust, which not only pollutes the working environment and affects worker health but also adheres to the dashboard surface, requiring additional cleaning and further reducing efficiency. Moreover, existing simple polishing equipment is limited in function, lacking flexibility and precision, making it difficult to adapt to the polishing needs of dashboards of varying shapes and sizes, and failing to achieve automated or intelligent polishing operations. Therefore, developing a grinding device for electric vehicle dashboards that can improve grinding efficiency, ensure grinding quality, and reduce dust pollution is of great practical significance.

An electric grinding head 3-2 is fixed inside the support plate 3-1. An upper magnetic ring 3-4 is fixed to the lower surface of the tray 3-1. The upper magnetic ring 3-4 magnetically attracts the lower magnetic ring 3-5. An acrylic tube 3-7 is fixed to the bottom of the lower magnetic ring 3-5. A silicone ring 3-6 is fixed to the bottom of the acrylic tube 3-7, which contacts the upper surface of the instrument panel workpiece 1-5. The vacuum cleaner 2 is fixed below the body structure 1. The vacuum port is connected to the vacuum pipe 4, which penetrates into the grinding end structure 3. A through hole is opened on the outer surface of the acrylic tube 3-7 for the vacuum pipe 4 to pass through. An infrared distance sensor is installed on the rear side of the lower surface of the tray 3-1 to monitor the distance between the electric grinding head 3-2 and the surface of the instrument panel workpiece 1-5 to be ground. A control box 1-3 is installed on the front side of the upper surface of the frame 1-1. The control box 1-3 controls the cross slide rail 1-4 to move the grinding end structure 3 back and forth and left and right above the instrument panel workpiece 1-5 for grinding operations. At the same time, the vacuum cleaner 2 sucks away the dust generated during grinding through the vacuum pipe 4.

[0017] Example 2: This electric vehicle dashboard grinding device features a frame 1-1 made of high-strength metal to ensure stability. The worktable 1-8 has a smooth, flat surface, and the hydraulic clamp 1-7 allows for flexible adjustment of clamping force to accommodate dashboard workpieces 1-5 of different sizes. The support frame 1-6 is height-adjustable, allowing for easy adjustment of the height of the cross slide rail 1-4 according to actual needs. In the grinding end structure 3, the servo cylinder 3-3 precisely controls the extension distance, and the support plate 3-1 is made of lightweight, high-strength material. The electric grinding head 3-2 can be replaced with different specifications according to grinding requirements. The acrylic tube 3-7 has high transparency for easy observation of the internal components, and the silicone ring 3-6 is soft and elastic, allowing for better contact with the surface of the dashboard workpiece 1-5. The vacuum cleaner 2 has adjustable power, allowing for adjustment of suction strength based on the amount of dust generated during grinding. The infrared distance sensor feeds back the distance information to the control box 1-3 in real time. The control box 1-3 controls the movement of the cross slide rail 1-4 and the operation of the electric grinding head 3-2 according to the preset program to realize automated grinding. At the same time, the dust suction pipe 4 continuously sucks the dust into the vacuum cleaner 2.

[0018] Example 3: In the body structure 1 of this electric vehicle dashboard grinding device, the frame 1-1 is designed with a shock-absorbing structure to reduce vibrations generated during grinding.

The hydraulic clamp 1-7 has a pressure display device, allowing for direct viewing of the clamping pressure. The servo electric cylinder 3-3 of the grinding end structure 3 has a self-locking function to ensure positional stability when the machine stops working. The electric grinding head 3-2 on the support plate 3-1 adopts a high-speed rotation design to improve grinding efficiency. The upper magnetic ring 3-4 and lower magnetic ring 3-5 have moderate magnetic attraction, facilitating the removal of the acrylic tube 3-7 for cleaning while ensuring that the acrylic tube 3-7 does not fall off during grinding. The vacuum cleaner 2 is equipped with a filter device to prevent secondary dust pollution. The control box 1-3 has multiple working modes, and the appropriate mode can be selected according to different grinding needs. The cross slide rail 1-4 precisely controls the grinding end structure 3 to move above the workpiece 1-5 on the instrument panel according to the instructions of the control box 1-3 to complete the grinding operation. At the same time, the dust suction pipe 4 effectively removes the dust.

[0019] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows: The instrument panel workpiece 1-5 to be ground is placed at a suitable position on the worktable 1-8 in the machine body structure 1. The instrument panel workpiece 1-5 is clamped and fixed by the hydraulic clamps 1-7 around the worktable 1-8.

Relevant parameters are set on the control box 1-3 according to the grinding requirements, such as the grinding movement trajectory and the working status of the electric grinding head 3-2. The control box 1-3 issues a command to fix the workpiece. The servo cylinder 3-3 on the cross slide rail 1-4 at the top of the support frame 1-6 on the rear side of the top surface of the frame 1-1 starts to work. The telescopic end of the servo cylinder 3-3 drives the support plate 3-1 to move, which in turn drives the electric grinding head 3-2 fixed inside the support plate 3-1 to move. The cross slide rail 1-4 controls the grinding end structure 3 to move back, forth, left and right above the workpiece 1-5 on the instrument panel, moving the electric grinding head 3-2 to the appropriate grinding starting position. At the same time, the infrared distance sensor installed on the rear side of the lower surface of the support plate 3-1 starts to work, monitoring the electric grinding head 3-2 in real time. -2 The distance between the grinding head and the workpiece 1-5 of the instrument panel to be ground is fed back to the control box 1-3 so as to adjust the grinding position; During the grinding process, the vacuum cleaner 2 fixed below the machine body structure 1 is turned on. The vacuum cleaner 2 performs dust removal through the dust suction pipe 4 connected to the inside of the grinding end structure 3. The end of the dust suction pipe 4 away from the grinding end structure 3 enters the working area through the through hole on the outer surface of the acrylic tube 3-7 to suck away the dust generated by grinding; The upper magnetic ring 3-4 and the lower magnetic ring 3-5 fixed on the lower surface of the support plate 3-1 The magnetic ring 3-5 is fixed to the bottom surface of the acrylic tube 3-7, which covers the bottom of the electric grinding head 3-2. The silicone ring 3-6 fixed to the bottom surface of the acrylic tube 3-7 contacts the upper surface of the instrument panel workpiece 1-5, providing some protection and auxiliary positioning. If the device needs to be moved during operation, it can be moved by the casters installed at the four corners of the bottom surface of the frame 1-1. After the grinding operation is completed, turn off the electric grinding head 3-2, the vacuum cleaner 2, and other equipment, release the hydraulic clamp 1-7, and remove the ground instrument panel workpiece 1-5.
