Description

Technical Field

[0001] This application relates to the field of CNC sanding machines for cookware, and in particular to CNC sanding machines for the top edge of irregularly shaped cookware.

[0002] Technical issues

[0003] In related technologies, ordinary cookware has a simple shape, and the requirements for CNC sanders used to grind it are relatively low. However, irregularly shaped cookware is diverse, with non-standard curved surfaces containing complex features such as multi-directional bends, edges, depressions, or protrusions. Their diameters, depths, curvatures, and materials vary, and the sanding path must strictly conform to the curved surface, making uniform sanding of irregularly shaped cookware difficult. Furthermore, users have extremely high visual and tactile requirements for high-end cookware, demanding complete consistency in gloss and texture from flat surfaces to irregularly shaped areas, and requiring consistent surface finish. Ordinary sanders struggle to maintain a constant grinding amount on complex curved surfaces. Each change of cookware type requires readjustment or replacement of fixtures, reprogramming, and resetting of sanding belt / wheel paths and pressure parameters. This results in long changeover times, severely impacting production efficiency, especially in small-batch, multi-variety production. Skilled technicians are required for operation, increasing labor costs and downtime. Therefore, it is evident that there are significant shortcomings in related technologies. Summary of the Invention

[0008] The motion assembly includes a first slide, a second slide, a third slide, and an adjusting cylinder;

[0009] The adjustment assembly includes a mounting plate, an adjustment plate, an arc-shaped plate, a lead screw, a pressure rod, a tension wheel, a contact wheel, and a guide wheel. The mounting plate is equipped with a first support shaft and a second support shaft. One end of the lead screw is hinged to the first support shaft, and the other end is hinged to the pressure rod. The other end of the pressure rod can rotate around the second support shaft. The tension wheel is movably connected to the pressure rod. The mounting plate also has multiple oblong holes through which the adjustment plate moves relative to the mounting plate. The adjustment plate has arc-shaped holes through which the arc-shaped plate moves relative to the adjustment plate. A third rotating shaft is mounted on the arc-shaped plate, and a contact wheel is mounted on the third rotating shaft. The grinding assembly includes a drive motor and a sanding belt. The drive motor drives the sanding belt to rotate. The sanding belt between the guide wheel and the contact wheel forms a flexible grinding area.

[0010] The workpiece clamping and rotating mechanism is equipped with an adapter plate, and the cookware is magnetically connected to the adapter plate; a rotary drive motor is installed at the bottom of the workpiece rotating assembly to drive the cookware to rotate; the workpiece clamping and rotating mechanism is also equipped with a transmission belt, and a linear drive motor is installed at one end of the transmission belt to drive the workpiece rotating assembly to move linearly.

[0011] Furthermore, a U-shaped seat and a first rotating shaft are provided on the side of the pressure rod facing the mounting plate. The U-shaped seat and the first rotating shaft are hinged together. A tensioning knob is provided at one end of the outer side of the first rotating shaft. The tensioning knob passes through the pressure rod, and the tensioning wheel is provided on the first rotating shaft.

[0012] Furthermore, a second rotating shaft is provided on the bow-shaped plate, and a guide wheel is provided on the second rotating shaft.

[0013] Furthermore, a rubber wheel is installed on the drive motor, and the outer wall of the rubber wheel passes through a sanding belt.

[0014] Furthermore, the mounting plate is also equipped with a hook handle to prevent springback.

[0015] Furthermore, the end of the hook shank is provided with a barb to engage with the limiting groove on the second support shaft.

[0016] Furthermore, a dust collection hood is installed below the grinding components.

[0017] Furthermore, the CNC sanding machine for the top edge of the irregularly shaped cookware is equipped with a switch box for controlling the machine tool; the switch box is equipped with a switch panel.

[0018] Furthermore, two opposing accordion plates are provided on the workbench, with accordion covers on opposite sides of the accordion plates. A slide plate and a side plate are connected between the accordion covers. Two slide rails are provided between the two accordion plates, and two fixed posts are also provided between the two accordion plates. Multiple sliders are provided under the slide plate, and the fixed posts pass through the sliders. The multiple sliders can move along the slide rails along the fixed posts.

[0019] Furthermore, a linear drive motor is provided at one end of the transmission belt, and a shaft seat, a slide, a fixed shaft, and a nut block are provided at the other end of the transmission belt. The shaft seat can move within the slide groove of the slide. A fixed shaft is fixedly connected to the shaft seat, and a nut block is provided on the fixed shaft for tightening, thus fixing the shaft seat and the slide. A clamping pad is also fixedly provided under the slide plate, and the transmission belt is limited by the clamping pad to prevent the transmission belt from shifting.

[0020] This application has at least one of the following beneficial effects:

[0021] 1. The motion and grinding mechanism precisely controls the position, posture, and trajectory of the sanding belt relative to irregularly shaped cookware. First, it moves linearly in the X, Y, and Z axes. Then, the adjustment assembly adjusts the positions of the lead screw, pressure rod, adjustment plate, and bow plate, further adjusting the positions of the tension wheel and contact wheel to form a flexibly adjustable triangular sanding belt. The sanding belt also features angle and tension adjustment functions, allowing its contact wheel to better conform to different angles around the cookware edge.

[0022] 2. The workpiece clamping and rotation mechanism controls the rotation of the workpiece rotating assembly mounted on the worktable around a vertical axis. This drives the pot to rotate, allowing the sanding belt to continuously and evenly grind the entire circumferential edge. On the other hand, it ensures smooth movement and high rigidity through high-precision linear guide rails. Linear motion is achieved through a linear drive motor, and rotary motion is achieved through a rotary drive motor.

[0023] 3. The CNC sanding machine for the top edge of irregularly shaped cookware in this application is an automated device specifically designed for grinding and polishing the top edges of cookware (woks, soup pots, etc.) (edge ​​rolling, flanging, burr removal, chamfering and polishing). Its core objective is to achieve high-efficiency, high-consistency, and high-surface-quality edge processing.

[0024] 4. This application can process complex features such as multi-directional bending, sharp corners, concavities or convexities of irregularly shaped cookware. The sanding path can achieve strict fit to the curved surface, meet users' extremely high requirements for the visual and tactile experience of high-end cookware, and ensure the consistency of gloss, texture and surface smoothness from flat to irregularly shaped areas.

[0047] Reference Figure 3 , Figure 4 and Figure 5The motion and grinding mechanism 2 has a first slide plate 211 at its bottom. The first slide plate 211 includes a first upper slide plate 212 and a first base 213. The first base 213 is fixedly mounted on the worktable 106 of the frame 11. The first base 213 is equipped with a first guide rod 214 and a first handwheel 215 for controlling the forward and backward displacement of the motion and grinding mechanism 2. Rotating the first handwheel 215 causes the first guide rod 214 to move the first upper slide plate 212 forward and backward. The second slide plate 221 includes a second upper slide plate 222 and a second base 223. The second base 223 is fixedly mounted above the first upper slide plate 212. The second base 223 is equipped with a second guide rod 224 and a second handwheel 225 for controlling the left and right displacement of the motion and grinding mechanism 2. Rotating the second handwheel 225 causes the second guide rod 224 to move the second upper slide plate 222 left and right. A stand 210 is fixedly mounted on the second upper slide plate 222. A third slide plate 231 is provided on the side wall of the stand 210. The third slide plate 231 includes a third upper slide plate 232 and a third base 233. The third base 233 moves vertically up and down in conjunction with the grinding mechanism. Rotating the third handwheel 235 causes the third guide rod 234 to move the third upper slide plate 232 vertically up and down. The third slide plate 231 is then used for coarse vertical adjustment.

[0048] Reference Figure 5 , Figure 6 and Figure 10 The third upper slide plate 232 is fixedly provided with a connecting plate 40, and an L-shaped mounting plate 41 is fixedly provided on the other side of the connecting plate 40. The L-shaped mounting plate 41 includes a long plate 42 and a short plate 43.

In this embodiment, the drive motor 44 is a three-phase asynchronous motor, and a rubber wheel 45 is mounted on the three-phase asynchronous motor. The outer wall of the rubber wheel 45 passes through an abrasive belt 46. The abrasive belt 46 is used to perform the actual grinding and polishing work.

[0050] Reference Figure 7 , Figure 8 and Figure 11On the other side of the long plate 42 of the mounting plate 41, a first support shaft 51 and a second support shaft 52 are fixedly installed. A lead screw 53 is hinged to the other end of the first support shaft 51, and a pressure rod 54 is hinged to the other end of the lead screw 53. The pressure rod 54 has multiple positioning holes, and its other end is connected to the other end of the second support shaft 52. A U-shaped seat 55 is provided on the side of the pressure rod 54 facing the long plate 42 of the L-shaped mounting plate 41. A nut seat is provided inside the U-shaped seat 55, and the nut seat and U-shaped seat 55 are hinged together. A first rotating shaft 61 is provided inside the nut seat. A tensioning knob 64 is provided at one end of the outer side of the first rotating shaft 61, and a tensioning wheel 77 is provided at the other end. Two bearings are provided on both sides of the tensioning wheel 77 for fixing it. The tensioning wheel 77 and the two bearings pass through the first rotating shaft 61 in sequence. The tension wheel 77 is fixed to the hinged U-shaped seat 55 and nut seat. The five-pointed star-shaped tension knob 64 can lift the tension wheel 77 to release tension, facilitating replacement of the sanding belt 46 or maintenance. (Refer to...) Figure 9 A hook handle 65 is also fixedly installed on the outer wall of the long plate 42 to prevent springback. A barb 66 is provided at the end of the hook handle 65, which cooperates with the limiting groove 67 on the second support shaft 52.

[0051] Loosen the tension knob 64, the lead screw 53 rotates and drives the pressure rod 54 to rotate, adjust the position of the tension wheel 77, tighten the tension knob 64 again to fix the tension wheel 77, and further fix the hook handle 65.

[0052] Reference Figure 7 , Figure 10 and Figure 11 An adjusting plate 71 is provided on the long plate 42 of the L-shaped mounting plate 41. Four oblong holes 72 are provided on the long plate 42 of the L-shaped mounting plate 41, through which the adjusting plate 71 moves relative to the long plate 42. An arc-shaped hole 73 is provided on the adjusting plate 71, through which an arc-shaped plate 74 moves relative to the adjusting plate 71. A second rotating shaft 62 is also provided on the arc-shaped plate 74, and a guide wheel 75 is provided on the second rotating shaft 62.

[0053] The dust collection hood 80 is fixedly installed on the outer wall of the long plate 42 of the L-shaped mounting plate 41 to collect waste and prevent sparks from flying. The dust collection hood 80 is equipped with a wrench 82, which is connected to the dust collection cover 81. The dust collection cover 81 is detachable for easy cleaning of the dust collection hood 80.

[0054] In the sanding assembly, a three-phase asynchronous motor provides power. The sanding belt 46 passes sequentially through a rubber wheel 45, a tension wheel 77, a contact wheel 76, and a guide wheel 75. The rubber wheel 45, tension wheel 77, and contact wheel 76 form the three corners of a triangle. The sanding belt 46 between the guide wheel 75 and the contact wheel 76 forms a flexible sanding area 4. This application can process complex features such as multi-directional bending, sharp edges, depressions, or protrusions in irregularly shaped cookware. The sanding path can achieve a strict fit to the curved surface, meeting users' extremely high requirements for the visual and tactile experience of high-end cookware, and ensuring consistency in gloss, texture, and surface finish from flat surfaces to irregularly shaped areas.

[0055] The motion and grinding mechanism 2 is the core power component of the CNC sander for the top edge of the irregularly shaped cookware. Drive motor 44: provides power for the sanding belt 46. Rubber wheel 45 is the drive wheel, i.e., the active wheel. Contact wheel 76: one of the most critical components. The flexible grinding area 4 between the guide wheel 75 and the contact wheel 76 directly contacts the edge of the cookware 112, directly affecting the grinding effect and contour adaptability; it needs to be wear-resistant and provide a certain degree of elastic cushioning. The contact wheel 76 adaptively floats within a certain range (radial) to follow the slight undulations or shape errors of the edge of the cookware 112, maintaining constant contact pressure and avoiding over-grinding or under-grinding. Tensioning wheel 77: maintains a constant tension on the sanding belt 46. Guide wheel 75: serves a guiding function. Sanding belt 46: different grit sizes and materials are selected according to process requirements (rough grinding, fine polishing, material), such as alumina, silicon carbide, zirconium corundum, sandpaper / abrasive cloth.

[0056] The motion and polishing mechanism 2 precisely controls the position, posture, and trajectory of the sanding belt 46 relative to the irregularly shaped cookware 112. First, based on the linear movement of the motion component in the three directions of X, Y, and Z axes, the adjustment component further adjusts the positions of the tension wheel 77 and the contact wheel 76 by adjusting the positions of the lead screw 53, pressure rod 54, adjustment plate 71, and bow plate 74, forming a flexibly adjustable triangular structure sanding belt 46. The sanding belt 46 is also equipped with angle adjustment and tension adjustment functions, so that the sanding belt 46 and the flexible polishing area 4 can better conform to different angles of the cookware edge.

[0057] Reference Figure 11 and Figure 12 The workpiece clamping and rotating mechanism 3 is used to precisely and stably fix the cookware 112 and drive it to rotate.

[0058] A workpiece rotating assembly 109 is fixedly mounted on the slide plate 110. A transition plate 111 is connected to the top of the workpiece rotating assembly 109. An irregularly shaped cookware 112 is mounted on the transition plate 111. The cookware 112 and the transition plate 111 are magnetically connected. The transition plate 111 can accommodate cookware 112 of different diameters, has low requirements for the shape of the pot bottom, and does not damage the outer wall of the pot. A rotary drive motor 113 is mounted at the bottom of the workpiece rotating assembly 109. The rotary drive motor 113 is fixedly mounted on the bottom of the sliding worktable 106 via a motor mounting base 114. Two switch boxes 115 are located above the small door for controlling the machine tool 1. Each switch box 115 has a switch panel 116.

[0059] The workbench 106 is provided with two opposing accordion plates 117. Accordion covers 118 are provided on opposite sides of the accordion plates 117. A slide plate 110 and a side plate 119 are connected between the accordion covers 118. (Refer to...) Figure 13 Two slide rails 120 are provided between the two accordion plates 117, and two fixed posts 121 are also provided between the two accordion plates 117. Multiple sliders 122 are provided under the slide plate 110. The fixed posts 121 pass through the sliders 122, and the multiple sliders 122 can move along the fixed posts 121 on the slide rails 120.

[0060] A drive belt 123 is installed under the skateboard 110, and one end of the drive belt 123 is connected to a linear drive motor 124. (See reference) Figure 14 The other end of the transmission belt 123 is provided with a bearing seat 125, a slide 126, a fixed shaft 127, and a nut block 128. The bearing seat 125 can move within the slide groove of the slide 126. The fixed shaft 127 is fixedly connected to the bearing seat 125, and the nut block 128 is provided on the fixed shaft 127 for tightening, thus fixing the bearing seat 125 and the slide 126. (Refer to...) Figure 15 A clamping pad 129 is fixedly installed under the slide plate 110, and the transmission belt 123 is limited by the clamping pad 129 to prevent the transmission belt 123 from shifting. The linear drive motor 124 drives the transmission belt 123 to move, thereby driving the slide plate 110 to move back and forth.

[0061] The workpiece clamping and rotating mechanism 3 controls the workpiece rotating assembly 109, which is mounted on the worktable 106, to rotate around a vertical axis, thereby rotating the cookware 112 and enabling the sanding belt 46 to continuously and evenly grind the entire circumferential edge. Simultaneously, it ensures smooth movement and high rigidity through a high-precision linear guide rail 120. Linear motion is achieved through a linear drive motor 124, and rotary motion is achieved through a rotary drive motor 113.

[0062] In summary, this application provides a CNC sanding machine for the top edge of irregularly shaped cookware 112, which is equipped with a flexibly adjustable triangular sanding belt 46, and the sanding belt 46 is also equipped with angle adjustment and tension adjustment functions, so that the sanding belt 46 and the flexible sanding area 4 can better conform to the different angles of the pot edge. This CNC sanding machine for the top edge of irregularly shaped cookware 112 is an automated device specifically used for grinding and polishing the top edge of cookware 112 (such as woks, soup pots, etc.) by rolling, flanging, deburring, and chamfering. Its core objective is to achieve high-efficiency, high-consistency, and high-surface-quality edge processing.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
