Description

Technical Field

[0001] The utility model relates to polishing equipment, in particular to a device for assisting a kettle in polishing the outer wall. Background Art

[0002] Kettles are a common water container in our daily lives. They are typically cylindrical, with an open top that tapers toward the mouth. They are typically made of alloy or stainless steel. During the production process, the exterior of the kettle is ground and polished. This not only improves its aesthetics but also removes dirt and bacterial harborages on the surface, enhancing its corrosion resistance. The smoother surface also makes it easier to clean, ensuring hygiene.

[0003] Currently, kettle polishing can be done manually or with equipment. Manual polishing is inefficient and difficult to guarantee quality. Improper operation can even cause deformation or damage to the kettle. Using equipment can significantly improve efficiency and ensure quality. However, existing equipment for polishing kettles is complex, expensive, and cumbersome to operate, requiring extensive training for workers. Utility Model Content

[0005] The kettle polishing device described in the present invention comprises a chassis that abuts against the bottom surface of the outer wall of the kettle, an inner chassis that abuts against the bottom of the inner wall of the kettle, and a pressure wheel that abuts against the inner side wall of the kettle; the chassis is connected to a rotating mechanism that drives it to rotate around an axis, the inner chassis and the pressure wheel are rotatably installed on the inner chassis bracket and the pressure wheel bracket respectively, the inner chassis bracket and the pressure wheel bracket are respectively connected to an axial driving mechanism that drives the inner chassis and the pressure wheel to extend into the interior of the kettle, and the pressure wheel bracket is also connected to a radial driving mechanism that drives the pressure wheel to abut against the inner side wall of the kettle.

[0006] Furthermore, the surface of the bottom plate that contacts the kettle is provided with a positioning recess having a shape consistent with the shape of the bottom surface of the kettle.

[0007] Furthermore, the bottom surface of the positioning recess is a plane, and the edge of the bottom surface transitions smoothly to the side wall in an arc shape.

[0008] Furthermore, the inner plate is a circular plate and is consistent with the shape of the inner bottom surface of the kettle.

[0009] Furthermore, the inner disk bracket includes a circular support disk, a support rod with one end connected and detachably fixed to the support disk, the other end of the support rod extending to the outside of the kettle to connect to the axial drive mechanism, and a concave positioning groove on the side of the inner disk. The support disk is arranged in the positioning groove and is connected to the inner wall of the positioning groove through the inner disk bearing.

[0010] Furthermore, the support plate and the support rod are connected and fixed by fixing screws.

[0011] Furthermore, the pressure wheel bracket includes a cylindrical wheel column, one end of the wheel column is provided with a connecting rod, and the other end of the connecting rod is connected to the axial drive mechanism or the radial drive mechanism; the pressure wheel is annular, the wheel column is arranged on the inner side of the ring of the pressure wheel and is connected to the pressure wheel through a pressure wheel bearing.

[0012] Furthermore, a clearance groove communicating with both ends is provided on the wheel column, and the clearance groove is extended in the radial direction, and the inner disc bracket passes through the clearance groove.

After the positioning is completed, the rotating mechanism drives the bottom plate to rotate, and the kettle and the inner plate also rotate synchronously with the bottom plate, and the pressure wheel also rotates with the kettle at the same time. The kettle is driven by a drive connected to it, and the polishing tool is pressed against the outer wall of the kettle, and forms an inner and outer relative contact with the pressure wheel.

[0026] The utility model provides a kettle polishing device.

[0027] The kettle polishing device of this embodiment includes a chassis 1 that is against the bottom surface of the outer wall of the kettle, an inner disk 2 that is against the bottom of the inner wall of the kettle, and a pressure wheel 3 that is against the inner side wall of the kettle; the chassis is connected to a rotating mechanism (not shown) that drives it to rotate around an axis, the inner disk and the pressure wheel are rotatably mounted on the inner disk bracket 4 and the pressure wheel bracket 5, respectively, the inner disk bracket and the pressure wheel bracket are respectively connected to an axial driving mechanism (not shown) that drives the inner disk and the pressure wheel to extend into the interior of the kettle, and the pressure wheel bracket is also connected to a radial driving mechanism (not shown) that drives the pressure wheel to press against the inner side wall of the kettle.

[0028] like Figure 1 、 2As shown, the kettle 100 to be polished is placed on the bottom plate, with the mouth of the kettle facing the inner plate and the pressure wheel. Then, the axial driving mechanism drives the inner plate and the pressure wheel through the inner plate bracket and the pressure wheel bracket to extend into the kettle from the mouth of the kettle, and the inner plate is pressed against the bottom of the kettle, thereby clamping the kettle from the inside and outside through the inner plate and the bottom plate. Then, the radial driving mechanism drives the pressure wheel to press against the inner side wall of the kettle, so that the kettle can be positioned. Figure 3 、 4 As shown; after the positioning is completed, the rotating mechanism drives the chassis to rotate, and the kettle and the inner disk also rotate synchronously with the chassis, and the pressure wheel also rotates with the kettle at the same time; on the outside of the kettle, the grinding wheel is driven by the driver connected to it to press on the outer wall of the kettle, and forms an inner and outer relative tightness between the pressure wheel. Thereafter, as the kettle continues to rotate, the grinding wheel gradually grinds the outer wall of the kettle to the required flatness; and in the process of grinding, the pressure wheel moves along the inner wall of the kettle driven by the axial driving mechanism, and the grinding wheel also moves to the relative position of the pressure wheel under its drive, thereby polishing the entire outer wall of the kettle; after polishing is completed, the grinding wheel, pressure wheel and inner disk are removed in turn, and the kettle can be taken away from the chassis.

[0029] The kettle polishing device features a positioning recess 11 on the surface of the base plate 1 that contacts the kettle, shaped like the kettle's bottom. This ensures stable positioning of the kettle and prevents radial displacement during processing, which could lead to quality issues. The bottom surface of the positioning recess 11 is flat, with a smooth arc-shaped transition from the bottom edge to the sidewall to accommodate the positioning needs of kettles of specific shapes. Similarly, the inner plate 2 can be a circular disc, shaped like the inner bottom of the kettle to match the shape of the kettle's bottom.

[0030] The kettle polishing device described above, the inner disk bracket 4 includes a circular support disk 41 and a support rod 42 which is connected and fixed to the support disk at one end. The support disk 41 and the support rod 42 can be connected and fixed by a fixing screw 43 to facilitate the installation, maintenance or replacement of support disks and inner disks of different models, and the other end of the support rod can be extended to the outside of the kettle to connect to the axial drive mechanism. At the same time, the side of the inner disk 2 has a concave positioning groove 21, and the support disk is arranged in the positioning groove and is connected to the inner wall of the positioning groove through an inner disk bearing 44, so that the inner disk can rotate relative to the support disk through the inner disk bearing.

[0031] The kettle polishing device described, the pressure wheel bracket 5 includes a cylindrical wheel column 51, one end of the wheel column is provided with a connecting rod 52, the other end of the connecting rod is connected to the axial drive mechanism or the radial drive mechanism, the axial drive mechanism and the radial drive mechanism can be separately set and connected to the connecting rod, or the radial drive mechanism can be installed on the axial drive mechanism, and the connecting rod is installed on the radial mechanism, the axial drive mechanism drives the radial drive mechanism and the pressure wheel into the kettle, and then the axial drive mechanism stops, and the radial drive mechanism drives the pressure wheel to press against the inner wall of the kettle; the pressure wheel 3 is annular, the wheel column is arranged on the inner side of the ring of the pressure wheel and is connected to the pressure wheel through a pressure wheel bearing 53, so that the pressure wheel can rotate relative to the wheel column. In addition, the wheel column 51 is provided with a clearance groove 54 connecting the two ends, and the clearance groove is extended in the radial direction. The support rod 42 of the inner disc bracket 4 passes through the clearance groove, and the clearance groove 54 extends to the connecting rod 52, so that the pressure wheel bracket and the inner disc bracket can move relative to each other in the radial direction along the clearance groove; this is because the size of the kettle mouth is relatively limited, and the inner disc bracket is passed through the wheel column, such as Figure 2 As shown, the inner disk and the pressure wheel can overlap with each other along the circumferential direction so that they can extend into the kettle through the kettle mouth together. After entering the kettle, the radial drive mechanism drives the pressure wheel bracket to move radially, as shown in FIG. Figure 4 As shown, the inner wall of the kettle is pressed tightly, which not only simplifies the device structure but also improves its working efficiency. In addition, in order to better coordinate the relative movement between the pressure roller bracket and the inner disc bracket, the support rod 42 of the inner disc bracket 4 can be set to be L-shaped, with one side of the L-shaped support rod passing through the clearance groove 54 to connect to the axial drive mechanism, and the other side of the L-shaped support rod is arranged parallel to the extension direction of the clearance groove.
