Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, and in particular relates to a surface polishing device for automotive parts. Background Technology

[0002] In the automotive parts manufacturing industry, surface polishing is a crucial process for ensuring the precision and appearance quality of parts. Traditional automotive parts surface polishing operations largely rely on manual hand-held polishing tools, which has several technical drawbacks: On the one hand, when operating manually, the operator needs to control the polishing force, angle and movement trajectory at the same time. The labor intensity is high and fatigue can easily lead to unstable force control, resulting in uneven polishing precision on the surface of parts, scratches, dents or over-polishing, which seriously affects the consistency of product quality. On the other hand, the fixing of parts often relies on simple clamps or manual handling, which results in poor fixing stability. During the polishing process, the parts are prone to positional displacement, causing the polishing area to deviate from the preset path. This positional displacement problem is particularly prominent for irregularly shaped, curved, or high-precision parts, which greatly increases the rework rate. Utility Model Content

[0003] This utility model addresses the problems in the prior art by proposing the following technical solution: A surface polishing device for automotive parts includes a robotic arm, a clamping mechanism, and a polishing machine. The clamping mechanism includes a base, a cylinder fixedly installed between the base and the interface of the robotic arm, and side slides slidably installed on both sides of the base. The side slides are fixedly connected to the robotic arm. A drive assembly is installed on the side of the base away from the robotic arm. The drive assembly is driven by two movable grippers, which are used to control the two movable grippers to move linearly in a direction away from or towards each other.

[0004] As a preferred embodiment of the above technical solution, the drive assembly includes a motor fixed in the inner wall of the base, the output end of the motor is fixedly connected to a bidirectional threaded rod, and a guide rod arranged parallel to the bidirectional threaded rod is fixedly installed on the inner wall of the base.

[0005] As a preferred embodiment of the above technical solution, the movable chuck is detachably mounted with a fixed frame, the fixed frame is fixedly connected to a movable block, the movable block has a threaded hole and a guide hole, the two threaded holes are respectively engaged with the threads of the bidirectional threaded rod in two different directions, and the guide hole is slidably engaged with the guide rod.

[0006] As a preferred embodiment of the above technical solution, each of the side slide plates has at least two slide grooves, and the side wall of the base is fixedly installed with a slider that slides in cooperation with the slide grooves.

[0007] As a preferred embodiment of the above technical solution, a soft rubber pad is fixedly fitted at the end of the movable clamp away from the base.

[0008] As a preferred embodiment of the above technical solution, it also includes a material platform disposed on one side of the robotic arm, a workpiece tray disposed above the material platform, the workpiece tray having several placement slots, and two handles fixedly installed on the workpiece tray.

[0009] The beneficial effects of this utility model are as follows: 1. This utility model achieves automated movement by using a robotic arm to drive the clamping mechanism. The sliding cooperation between the side slide plate and the base with the sliding groove-slider effectively constrains the overall movement trajectory and avoids the positional deviation problem of traditional hand polishing.

[0012] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0013] Example like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a surface polishing device for automotive parts includes a robotic arm 10, a clamping mechanism 20, and a polishing machine 30. The clamping mechanism 20 includes a base 21, a cylinder is fixedly installed between the base 21 and the interface of the robotic arm 10, and side slide plates 22 are slidably installed on both sides of the base 21. The side slide plates 22 are fixedly connected to the robotic arm 10. A drive assembly is installed on the side of the base 21 away from the robotic arm 10. The drive assembly is driven by two movable chucks 25, which are used to control the two movable chucks 25 to move linearly in a direction away from or close to each other.

[0014] Specifically, the robotic arm 10 acts as a mobile carrier, driving the clamping mechanism 20 and polishing-related components to adjust their positions, thereby achieving automated movement and solving the positional offset problem of traditional hand-held polishing. The cylinder between the base 21 and the interface of the robotic arm 10 is used to drive the sliding plate 22 on the opposite side of the base 21 to move, adjusting the working distance of the clamping mechanism 20. The drive component controls the opening and closing of the two movable grippers 25 to achieve stable clamping of automotive parts, replacing manual hand-held operation and solving the problem of poor force control.

[0015] like Figure 2 and Figure 3 As shown, the drive assembly includes a motor fixed in the inner wall of the base 21, a bidirectional threaded rod fixedly connected to the output end of the motor, and a guide rod fixedly installed in parallel with the bidirectional threaded rod on the inner wall of the base 21.

[0016] Specifically, the motor on the inner wall of the base 21 provides power, and its output end is connected to a bidirectional threaded rod with opposite thread directions at both ends. By rotating, it drives two movable chucks 25 to make opposite linear movements, moving closer or further away from each other to achieve clamping or releasing actions. A guide rod parallel to the bidirectional threaded rod is used to limit the movement direction of the subsequent moving block 23, preventing it from rotating with the threaded rod and ensuring the linearity and accuracy of the movement of the movable chucks 25.

[0017] like Figure 2 and Figure 3 As shown, the movable chuck 25 is detachably mounted with a fixed frame 24, and the fixed frame 24 is fixedly connected to a movable block 23. The movable block 23 has a threaded hole 231 and a guide hole 232. The two threaded holes 231 are respectively engaged with the threads in two different directions of the bidirectional threaded rod, and the guide hole 232 is slidably engaged with the guide rod.

[0018] Specifically, the movable chuck 25 is connected to the moving block 23 via the fixed frame 24, and the fixed frame 24 is detachable, which facilitates the replacement of movable chuck 25 of different specifications according to the size of the parts, thereby improving the versatility of the device. The threaded hole 231 of the moving block 23 cooperates with the bidirectional threaded rod to convert the rotational motion of the threaded rod into the linear motion of the moving block 23, thereby realizing the opening and closing of the movable chuck 25. The guide hole 232 slides with the guide rod to further constrain the movement trajectory of the moving block 23, ensuring that the movable chuck 25 moves accurately and preventing the parts from shifting during clamping.

[0019] like Figure 2 and Figure 3 As shown, a side slide plate 22 has at least two slide grooves 221, and a slider that slides in cooperation with the slide grooves 221 is fixedly installed on the side wall of the base 21.

[0020] It should be noted that each side slide plate 22 has at least two slide grooves 221, and the slider on the side wall of the base 21 cooperates with them. Through multi-point support, the movement trajectory of the base 21 is restricted, preventing the base 21 from tilting or shifting under the drive of the cylinder, ensuring the overall stability of the clamping mechanism 20, and improving the positional accuracy during polishing.

[0021] like Figure 2 and Figure 3 As shown, a soft rubber pad 26 is fixedly fitted at the end of the movable clamp 25 away from the base 21.

[0022] It should be noted that the soft rubber pad 26 is elastic, which can buffer the clamping force and prevent the movable chuck 25 from directly contacting the surface of the parts and causing squeezing damage (such as scratches or deformation). At the same time, it increases the friction between the movable chuck 25 and the parts, prevents the parts from slipping during clamping, and improves clamping stability.

[0023] like Figure 1 and Figure 4 As shown, it also includes a material platform 40 located on one side of the robotic arm 10. A workpiece tray 50 is located above the material platform 40. The workpiece tray 50 has several placement slots 51 and two handles 52 are fixedly installed on the workpiece tray 50.

[0024] Specifically, the material table 40 on one side of the robotic arm 10 provides a placement platform for the workpiece tray 50, enabling the orderly storage of parts. The placement slot 51 of the workpiece tray 50 is used to position the parts to be polished or already polished, making it convenient for the robotic arm 10 to accurately grasp and put back, improving the efficiency of automated operation. The two handles 52 on the workpiece tray 50 facilitate manual handling, simplify the loading and unloading process, and are suitable for batch processing scenarios.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
