[0032] Embodiments

[0033] Please refer to Figures 1-5 The embodiment provides a self-limiting polishing tool for a battery tray, which comprises a mounting fixed seat 1, a fixed tool 2, a sand belt 3 and a driving device 4, the fixed tool 2 is slidably arranged in the mounting fixed seat 1 along the horizontal direction; the fixed tool 2 is rotationally provided with a driving roller 6 and a driven wheel 7, and the sand belt 3 is wound around the driving roller 6 and the driven wheel 7 respectively; as Figure 2 and Figure 3As shown, the left side of the abrasive belt 3 is vertically arranged, and the left side of the abrasive belt 3 is the polishing surface 16; the driving device 4 is in transmission connection with the driving roller 6, and the driving device 4 of the embodiment preferably adopts a pneumatic driving device, such as a pneumatic motor and other existing products. When the product is actually manufactured, the parts of the mature polishing equipment on the market are modified, and the driving device 4 adopts the pneumatic driving mechanism used by the FS30 air grinder, which can be in transmission with the driving roller 6 through gears.

[0034] When installed, two polishing tools provided by the present application can be arranged oppositely and fixed on the top of the workbench through the mounting fixing seat 1, and the power battery tray 14 is located between the two polishing tools, as shown in Figure 5 As shown, the weld polishing area of the power battery tray 14 is located at the corner recess of the power battery tray 14, and the polishing surface 16 of the abrasive belt 3 abuts against the weld polishing area of the power battery tray 14.

[0035] The pneumatic driving device is connected to the gas source for gas supply, and at this time the driving roller 6 is driven to rotate by the pneumatic driving device. The outer wall of the driving roller 6 of the embodiment is coarsely arranged, which can improve the friction between the driving roller 6 and the abrasive belt 3. The driving roller 6 drives the abrasive belt 3 to rotate along the driven roller 7, and the abrasive belt 3 continuously rubs and polishes the polishing area of the weld of the power battery tray 14.

[0036] When dealing with different processing scenes, only the size and processing direction of the abrasive belt 3 need to be changed, without the need for programming control of the gantry, and the operation difficulty is significantly reduced. Semi-automatic processing can allow a single person to operate multiple devices, which can significantly reduce labor costs. Using the polishing tool instead of the gantry milling edge releases the processing capacity of the gantry, so that the high gantry equipment can be applied to other product size processing with higher precision requirements.

[0037] Compared with the gantry equipment, the polishing tool can better adapt to the complex shape and structure of the power battery tray. For some special-shaped or curved tray edges, the polishing surface can be flexibly adjusted and operated to easily complete the processing task. The gantry milling machine may need complex programming and tool path planning when processing complex shapes, and its efficiency and cost are not as good as the polishing tool for small-batch special-shaped processing.

[0038] The polishing tool has relatively small and uniform force on the workpiece during polishing, unlike the milling process of the gantry, which may generate a large cutting force, thereby causing stress concentration on the surface of the workpiece. For power battery trays that require high structural strength and stability, using a polishing device can reduce stress concentration and improve the overall quality and service life of the tray. The polishing device can finely polish the surface of the workpiece to make it smoother, flatter, and lower in roughness.

[0039] AsFigures 1-3 As shown, in some embodiments of the present invention, the fixed tool 2 is provided with a horizontal linear guide rail 5, the linear guide rail 5 is provided with a guide rail slider 8 for horizontal sliding, and the fixed tool 2 is arranged on the guide rail slider 8. The present invention facilitates the sliding of the fixed tool 2 along the horizontal direction for grinding by providing the linear guide rail 5.

[0040] like Figures 1-3 As shown, in some embodiments of the present invention, a mounting bolt 9 is further included, which passes through the fixed tool 2 and is threadedly connected to the guide rail slider 8. The present invention facilitates the installation of the fixed tool 2 through the mounting bolt 9 and also facilitates the removal and replacement of the fixed tool 2 by providing the mounting bolt 9.

[0041] like Figures 1-5 As shown, in some embodiments of the present invention, the mounting base 1 is provided with a mounting block 10, and a spring 15 is provided between the mounting block 10 and the guide rail slider 8. There are two mounting blocks 10 and they are spaced apart. The guide rail slider 8 is located between the two mounting blocks 10, and a spring 15 is provided between the two mounting blocks 10 and the guide rail slider 8.

[0042] The utility model is provided with a spring 15, such as Figure 2 and Figure 4 As shown, before grinding, the grinding surface 16 of the abrasive belt 3 is first brought into contact with the weld bead grinding area, and the power battery tray 14 is moved to push the guide rail slider 8 to move a certain distance. At this time, the spring 15 on one side is stretched, and tension can be applied by the spring 15 on that side. During grinding, the tension of the spring 15 can pull the guide rail slider 8 to automatically slide for grinding, which is convenient to operate. In terms of machining accuracy, the spring 15 transmits the linear guide 5 to evenly apply force to the machining surface, improving the grinding quality.

[0043] like Figures 1-4 As shown, in some embodiments of the present invention, the longitudinal cross-section of the mounting base 1 is L-shaped. In this way, the vertical side of the mounting base 1 is used to install the linear guide 5, and the horizontal side of the mounting base 1 is used to be installed and fixed on the workbench for easy operation.

[0044] like Figures 1-3 As shown, in some embodiments of the present invention, the number of driven wheels 7 is two and they are spaced apart. The fixed tool 2 is provided with a tensioning wheel 11, and the abrasive belt 3 is wound around the tensioning wheel 11. The present invention is provided with a tensioning wheel 11 and two driven wheels 7, as shown in FIG. Figure 2 As shown, the two driven wheels 7 are located on the left and spaced apart up and down, the driving roller 6 and the tensioning wheel 11 are located on the right, and the tensioning wheel 11 is located below the driving roller 6, so that the sanding belt 3 is tightened, thereby facilitating the sanding belt 3 to perform sanding operations.

[0045] like Figures 1-3As shown, in some embodiments of the present invention, an L-shaped rotating rod 12 is provided between the tensioning wheel 11 and the fixed tool 2, and the middle part of the rotating rod 12 is rotatably provided on the fixed tool 2; a tension spring 13 is provided between one end of the rotating rod 12 and the fixed tool 2, and the tensioning wheel 11 is rotatably provided on the other end of the rotating rod 12. Figure 3 As shown, the tension spring 13 applies a pulling force toward the right to the bottom of the rotating rod 12. At this time, the tensioning wheel 11 at the bottom end of the rotating rod 12 can move downward and tightly abut against the sanding belt 3, so as to make the sanding belt 3 tight.

[0046] like Figures 1-5 As shown, in some embodiments of the present invention, the fixing fixture 2 is provided with a self-limiting fixing block 17. The present invention provides the self-limiting fixing block 17, which is located near the grinding surface 16. During the grinding process of the grinding surface 16, before the grinding surface 16 contacts the power battery tray 14, the self-limiting fixing block 17 first contacts the power battery tray 14. In this way, the self-limiting fixing block 17 is in contact with the power battery tray 14 to limit the position. At this time, the guide rail slider 8 cannot continue to slide under the tension of the spring 15, and the sanding belt 3 idles, thereby avoiding the occurrence of excessive grinding.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application.

[0048] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of this application is limited by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in this application. Any figure mark in the claims should not be regarded as limiting the claim involved. For those skilled in the art, various changes and variations of the present invention are possible.
