Description

Technical Field

[0001] This application relates to the field of stainless steel product grinding technology, and in particular to a fine grinding mechanism for stainless steel products and an edge grinding machine for stainless steel products. Background Technology

[0002] During the manufacturing process of stainless steel products, the edges of the products need to be polished to improve the surface smoothness and aesthetics of the edges, and also to remove surface defects.

[0003] Edge grinding machines typically perform fine grinding on the edges of stainless steel products to make the edges smoother. In related technologies, the fine grinding mechanism has a grinding belt, and the edges of the stainless steel product are finely ground through the friction of the grinding belt. However, the friction surface rubs against the edge of the stainless steel product at only one point, resulting in a short lifespan for the grinding belt. This necessitates frequent replacement of the grinding belt, leading to decreased processing efficiency and increased consumable costs. Utility Model Content

[0009] A swinging member is connected to the base and to the fine grinding structure. One end of the swinging member along its length direction can rotate relative to the base, and the other end can move relative to the base along an arc-shaped trajectory.

[0010] Under the drive of the first driving structure, the seat can move along the first direction to drive the swinging member to swing along the arc trajectory, thereby changing the friction position between the friction surface and the edge of the stainless steel product located in the fine grinding station.

[0011] In some embodiments, the seat body has a limiting groove along the arcuate trajectory, and the other end of the swing member along its length direction is disposed in the limiting groove and can move along the extension direction of the limiting groove.

[0017] In some embodiments, the base further includes a second driving structure, which is connected to the base body via the first driving structure;

[0018] The second driving structure is used to drive the seat to move along the second direction, so that the friction surface of the fine grinding structure can finely grind the edge of the stainless steel product located at the fine grinding station along the second direction.

[0019] In some embodiments, the base further includes a third driving structure, which is connected to the base body via the second driving structure and is also connected to the second driving structure;

[0020] The third driving structure is used to drive the seat to move along the height direction.

[0021] In some embodiments, the fine grinding structure includes a grinding belt and a drive member, a drive wheel, a driven wheel, and a fine grinding wheel respectively mounted on the oscillating member;

[0022] The abrasive belt is wound around the driving wheel, the driven wheel and the fine grinding wheel, and has the friction surface; the driving member is connected to the driving wheel in a transmission.

[0023] Under the drive of the driving component, the fine grinding wheel can work with the abrasive belt to finely grind the edges of the stainless steel product.

[0024] In some embodiments, the abrasive belt is a soft abrasive belt;

[0025] And / or, the fine grinding assembly further includes a mounting plate, which is mounted on the oscillating member, and the fine grinding structure is disposed on the mounting plate, wherein the mounting plate can rotate relative to the oscillating member by a set angle and stop at a position corresponding to the set angle, so as to adjust the angle of the friction surface relative to the fine grinding station.

The second placement component is provided with a coarse grinding station, and the coarse grinding component is used to coarsely grind the stainless steel products located at the coarse grinding station.

[0029] The fine grinding mechanism and edge grinding machine for stainless steel products based on the embodiments of this application can prevent the friction surface from rubbing against the stainless steel product at one position along its width direction by changing the friction position between the friction surface and the edge of the stainless steel product located at the fine grinding station. This can extend the service life of the friction surface of the fine grinding structure. In this way, on the one hand, it can avoid the reduction in production efficiency caused by frequent replacement of the fine grinding structure, and on the other hand, it can effectively reduce the cost of consumables.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0037] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0038] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] Please refer to the following: Figures 1-3 This application proposes a stainless steel edge grinding machine 100 for grinding the edges of stainless steel products to provide the surface smoothness and aesthetics of the edges of stainless steel products, and at the same time remove surface defects of the edges of stainless steel products. The stainless steel products may include stainless steel pots, stainless steel bowls and stainless steel basins, etc., and the type of stainless steel products is not specifically limited here.

[0041] In this embodiment of the application, the stainless steel product edge grinding machine 100 includes a machine base 10, a fine grinding mechanism 20, and a coarse grinding mechanism (not shown in the figure).

[0042] The machine base 10 mainly serves to support the various mechanisms of the edge grinding machine 100. Specifically, the coarse grinding mechanism and the fine grinding mechanism 20 are respectively located on the machine base 10.

[0043] The fine grinding mechanism 20 is used to finely grind the edges of stainless steel products. Specifically, the fine grinding mechanism 20 includes a first placement component 21 and a fine grinding component 22. The first placement component 21 is located on the machine base 10 and has a fine grinding station 211A, which is used to place stainless steel products, specifically the stainless steel products to be finely ground. The fine grinding component 22 is located on the machine base 10 and is used to finely grind the stainless steel products located at the fine grinding station 211A.

[0044] The rough grinding mechanism is used to rough grind the edges of stainless steel products. Specifically, the rough grinding mechanism includes a second placement assembly and a rough grinding assembly. The second placement assembly is located on the machine base 10 and has a rough grinding station. The rough grinding station is used to place the stainless steel products, which are the stainless steel products to be rough ground. The rough grinding assembly is used to rough grind the stainless steel products located at the rough grinding station.

[0045] It should be noted that the coarse grinding component and the fine grinding component 22 can grind the same edge of the stainless steel product. That is, after the coarse grinding component finishes grinding the edge, the fine grinding component 22 further grinds the edge to improve the grinding effect. Alternatively, the coarse grinding component and the fine grinding component 22 can grind the edges of the stainless steel product in a corresponding manner according to the grinding requirements of different edges. That is, some edges have lower grinding requirements, so they can be ground by the coarse grinding component, while some edges have higher grinding requirements, so they can be ground by the fine grinding component 22. This embodiment does not specifically limit the grinding method. To better understand, the difference between the fine grinding component 22 and the coarse grinding component is that the diameter of the abrasive particles in the fine grinding component 22 is smaller than the diameter of the abrasive particles in the coarse grinding component. Therefore, the effects of coarse grinding and fine grinding can be distinguished after grinding.

[0046] Please refer to the following: Figures 1-3 In one embodiment of this application, the fine grinding assembly 22 includes a base 221 and a fine grinding structure 222. The base 221 is disposed on the machine base 10, and the fine grinding structure 222 is mounted on the base 221 and has a friction surface 2221A. The friction surface 2221A is inclined relative to the side of the stainless steel product, and the friction surface 2221A is used to fine grind the stainless steel product located at the fine grinding station 211A.

[0047] The fine grinding structure 222 can move relative to the base 221 along the height direction z and the first direction x, so as to change the friction position between the friction surface 2221A and the edge of the stainless steel product located at the fine grinding station 211A.

[0048] This configuration allows for adjustment of the friction position of the friction surface 2221A along its width direction with the stainless steel product, preventing the friction surface 2221A from continuously rubbing against the stainless steel product at one position along its width direction. This extends the service life of the friction surface 2221A of the fine grinding structure 222. In this way, on the one hand, it avoids frequent replacement of the fine grinding structure 222, which would reduce production efficiency, and on the other hand, it effectively reduces the cost of consumables.

[0049] Please refer to the following: Figures 1-3 In some embodiments, the base 221 includes a base body 2211 and a first driving structure 2212, the first driving structure 2212 being connected to the base body 2211, the first driving structure 2212 being a linear module, and the first driving structure 2212 being connected to the base body 2211.

[0050] The fine grinding assembly 22 also includes a swing member 223, which can be a plate structure. The swing member 223 is connected to the base 2211 and to the fine grinding structure 222, serving to connect the fine grinding structure 222 to the base 2211. The swing member 223 can have a length direction, with one end of the swing member 223 rotatable relative to the base 2211 along its length direction, and the other end movable relative to the base 2211 along an arcuate trajectory.

[0051] Under the drive of the first drive structure 2212, the seat 2211 can move along the first direction x, so as to drive the swing member 223 to swing along the arc trajectory, thereby changing the friction position between the friction surface 2221A and the edge of the stainless steel product located in the fine grinding station 211A.

[0052] In some feasible structural forms, one of the swing member 223 and the base 2211 is provided with a slider, and the other is provided with a slide rail that cooperates with the slider. The slide rail is arranged in an arc shape so that the swing member 223 can swing along the arc trajectory.

[0053] Thus, by swinging the swinging member 223 along the arc trajectory, the fine grinding structure 222 can move relative to the base 221 in two directions, namely, along the height direction z and the first direction x. Compared with setting two driving mechanisms to drive the fine grinding structure 222 to move along the height direction z and the first direction x respectively, the structure of this embodiment is simpler and has better synchronization.

[0054] Please refer to the following: Figures 1-3 In some embodiments, the seat 2211 has a limiting groove 2211A along an arc-shaped trajectory, and the other end of the swing member 223 along its length direction is located in the limiting groove 2211A and can move along the extension direction of the limiting groove 2211A.

[0055] In this way, the swinging member 223 can swing along an arc trajectory by cooperating with the limiting groove 2211A and the swinging member 223. The limiting groove 2211A can limit the trajectory range of the swinging member 223 and play a limiting role. Thus, under the drive of the first drive structure 2212, the swinging member 223 can be automatically oscillating. Compared with the structure of sliders and slide rails, the structure of this embodiment is simpler and the cost is lower.

[0056] In an alternative form, the other end of the swing member 223 along its length direction may have a limiting groove 2211A along an arc-shaped trajectory, and the seat 2211 may be disposed in the limiting groove 2211A. This embodiment does not limit this.

[0057] Please refer to the following: Figures 1-3Furthermore, the oscillating component 223 includes an oscillating body 2231 and a rolling shaft. The oscillating body 2231 is the main component of the oscillating component 223, which is connected to the fine grinding structure 222, and one end of it is rotatably connected to the base 2211 along its length. The rolling shaft is a cylindrical column, which is connected to the other end of the oscillating body 2231 along its length and is inserted into the limiting groove 2211A.

[0058] In this configuration, the rolling shaft rolls against the side wall of the limiting groove 2211A, thereby driving the swing body 2231 to move relative to the seat 2211 along an arc-shaped trajectory. This arrangement reduces the friction between the rolling shaft and the side wall of the limiting groove 2211A, further improving the smoothness of the swing body 2231 during the swinging process.

[0059] Optionally, the rolling shaft includes two, which are connected to opposite sides of the swing body 2231. The swing member 223 has two limiting grooves 2211A, and one of the rolling shafts is inserted into one of the limiting grooves 2211A. This can improve the smoothness and stability of the swing member 223 when it swings.

[0060] Since some of the processed stainless steel products have a square structure, they have four edges connected end to end, and all four edges need to be finely ground. Therefore, in some embodiments, the second placement assembly includes a placement table 211 and a rotary table 212. The placement table 211 has a fine grinding station 211A, and the rotary table 212 is located on the machine base 10, with the placement table 211 mounted on top of it. The rotary table 212 drives the placement table 211 to rotate. Thus, with the rotary table 212 in place, the rotation of the placement table 211 can be controlled to automatically adjust the position of the stainless steel product relative to the fine grinding structure 222.

[0061] Understandably, after the fine grinding structure 222 has finished fine grinding one edge of the stainless steel product, it needs to fine grind the other edge. At this time, the first driving structure 2212 can drive the seat 2211 to move along the first direction x to move away from the placement table 211, thereby avoiding interference with the rotation of the stainless steel product. Then, the rotating table 212 drives the placement table 211 to rotate, thereby causing the stainless steel product to rotate. After the rotation is completed, the first driving structure 2212 can drive the seat 2211 to move along the first direction x to move closer to the placement table 211, thereby fine grinding the other edge.

[0062] In this embodiment, by setting up the rotary table 212, the position of the stainless steel product relative to the fine grinding structure 222 can be automatically adjusted, so that the fine grinding structure 222 can realize the automated fine grinding operation on multiple edges of the stainless steel product, greatly improving the efficiency of the fine grinding operation.

[0063] Please refer to the following: Figures 1-3 In some embodiments, the base 221 further includes a second driving structure 2213, which may be a linear module.

[0064] The second drive structure 2213 is disposed on the machine base 10 and is connected to the base 2211 via the first drive structure 2212. The second drive structure 2213 is used to drive the base 2211 to move along the second direction y, so that the friction surface 2221A of the fine grinding structure 222 can finely grind the edge of the stainless steel product located at the fine grinding station 211A along the second direction y.

[0065] Since some of the processed stainless steel products have a square structure, the edges of the stainless steel products are arranged in a straight line, that is, extending along the second direction y. Based on this, when fine grinding the edges of the stainless steel products, it is necessary to fine grind the entire edge of the stainless steel products. Therefore, under the drive of the second drive structure 2213, the fine grinding structure 222 can move back and forth along the second direction y to fine grind the entire edge of the stainless steel products.

[0066] Of course, this application is not limited to this. In other embodiments, the base 221 and the fine grinding structure 222 may remain stationary, and the second placement component may reciprocate along the second direction y.

[0067] It should be noted that in the layout of multiple mechanisms of some edge grinding machines 100, the fine grinding component 22 and the coarse grinding component are arranged opposite to each other. Therefore, the first direction x and the second direction y are arranged in parallel, and the second direction y and the first direction x are arranged in parallel.

[0068] Please refer to the following: Figures 1-3 In some embodiments, the base 221 further includes a third driving structure 2214, which can be a linear module. The third driving structure 2214 is connected to the seat body 2211 through the first driving structure 2212 and to the second driving structure 2213, wherein the third driving structure 2214 is used to drive the seat body 2211 to move along the height direction z.

[0069] Understandably, in some scenarios, it is necessary to fine grind different edges of stainless steel products along the height direction z. In this case, the third drive structure 2214 can drive the base 2211 to move along the height direction z to make automatic adjustments. Alternatively, in other scenarios, when it is necessary to change the style of stainless steel products for fine grinding, since the edge heights of different styles of stainless steel products are different, the third drive structure 2214 can drive the base 2211 to move along the height direction z to make automatic adjustments.

[0070] Please refer to the following: Figures 1-3In some embodiments, the fine grinding structure 222 includes a grinding belt 2221, a driving member 2222, a driving wheel 2223, a second driven wheel 2224, and a fine grinding wheel 2225. The grinding belt 2221 has a friction surface 2221A with abrasive particles. The abrasive particles rub against the edge of the stainless steel product, thus achieving fine grinding of the edge. The grinding belt 2221 is wound around the driving wheel 2223, the second driven wheel 2224, and the fine grinding wheel 2225. The driving member 2222, the driving wheel 2223, the second driven wheel 2224, and the fine grinding wheel 2225 are respectively mounted on the oscillating member 223. The driving member 2222 can be a drive motor, and the driving member 2222 is connected to the driving wheel 2223 in a transmission connection. Understandably, driven by the drive component 2222, the drive wheel 2223 can rotate, thereby enabling the abrasive belt 2221 to move around the drive wheel 2223, the second driven wheel 2224, and the coarse grinding wheel.

[0071] Driven by the drive component 2222, the fine grinding wheel 2225 works in conjunction with the abrasive belt 2221 to finely grind the edges of the stainless steel product. This changes the position of friction between the friction surface 2221A and the edge of the stainless steel product, preventing prolonged friction on a single area along the length of the friction surface 2221A. This ensures effective friction while extending the service life of the abrasive belt 2221. Simultaneously, the second driven wheel 2224 acts as a tensioning wheel, providing tension to the abrasive belt 2221 and preventing it from becoming loose, thus guaranteeing the effective friction between the abrasive belt 2221 and the edge of the stainless steel product.

[0072] Optionally, the abrasive belt 2221 can be a soft abrasive belt, which can ensure the smoothness of stainless steel products after fine grinding, thereby improving the fine grinding effect.

[0073] Please refer to the following: Figures 1-3 In some embodiments, the fine grinding assembly 22 further includes a mounting plate 224, which is mounted on the swing member 223, and the fine grinding structure 222 is disposed on the mounting plate 224.

[0074] The mounting plate 224 can rotate relative to the oscillating member 223 by a set angle and stop at the position corresponding to the set angle to adjust the angle of the friction surface 2221A relative to the fine grinding station 211A. In some exemplary structural forms, the oscillating member 223 is provided with a mounting groove, which is arc-shaped. The mounting plate 224 can rotate relative to the oscillating member 223 by a set angle by being installed at different positions in the mounting groove.

[0075] In this way, the angle of the rubbing surface relative to the fine grinding station 211A can be adjusted according to the actual fine grinding position of the stainless steel product, and the fine grinding structure 222 is set on the mounting plate 224, which makes it easy to adjust the fine grinding structure 222 as a whole.
