Description

Technical Field

[0001] This application relates to the field of stainless steel product grinding technology, and in particular to a rough 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] In related technologies, edge grinding machines typically use rough grinding to smooth the edges of stainless steel products. However, when rough grinding the edges of stainless steel products, the rough grinding mechanism is manually operated to bring it into contact with the edge. This method introduces certain processing errors, such as the rough grinding structure being too close or too far from the edge, resulting in larger dimensional errors at the edge of the finished product and lower product consistency.

[0011] In some embodiments, the coarse grinding assembly further includes a limiting member connected to the base;

[0012] The limiting member is used to limit the range of rotation of the rough grinding structure toward the stainless steel product.

[0013] In some embodiments, the limiting member is a limiting cylinder, and the limiting cylinder is rotatably connected to the base;

The abrasive belt is wound around the driving wheel, the driven wheel and the coarse grinding wheel. The driving member is connected to the driving wheel in a transmission.

[0019] Under the drive of the driving component, the coarse grinding wheel can cooperate with the abrasive belt to coarsely grind the edge of the stainless steel product.

[0020] In some embodiments, the base includes a seat and a first drive structure, the seat being connected to the coarse grinding structure, and the coarse grinding structure being movable relative to the seat;

[0021] The first driving structure is connected to the base and is used to drive the base to move along a first direction so that the rough grinding structure can rough grind the edge of the stainless steel product located at the rough grinding station along the first direction.

[0022] In some embodiments, the base further includes a second driving structure connected to the base body to drive the base body to move along a second direction, the second direction being perpendicular to the first direction, and the first driving structure being connected to the second driving structure to drive the base body to move along the first direction via the second driving structure;

[0023] The first placement assembly includes a placement table and a rotary table. The placement table has the rough grinding station and is mounted on the rotary table. The rotary table can drive the placement table to rotate.

[0024] In some embodiments, the base further includes a third driving structure, which is connected to the first driving structure and also to the second driving structure;

[0025] The third driving structure is used to drive the second driving structure to move along the height direction, so as to drive the seat to move along the height direction.

The fine grinding component and the second placement component are respectively disposed on the machine tool. The second placement component is provided with a fine grinding station. The fine grinding component is used to fine grind the edge of the stainless steel product located at the fine grinding station.

[0028] Based on the rough grinding mechanism and edge grinding machine for stainless steel products according to the embodiments of this application, the rough grinding structure can move naturally toward the edge of the stainless steel product under its own gravity, and will stop after contacting and pressing against the edge of the stainless steel product, and then start the rough grinding operation. In this way, when rough grinding the edge of any stainless steel product, the gravity of the rough grinding structure can be used to make the rough grinding structure move toward the stainless steel product, and ensure that the contact position between the rough grinding structure and the edge of the stainless steel product is as consistent as possible each time. Therefore, when performing subsequent rough grinding operations, it can be ensured that the edge of the stainless steel product is as uniform in size as possible after rough grinding, thereby improving the consistency of the stainless steel product output.

[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.

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

[0041] The machine base 10 mainly serves to support the various mechanisms of the edge grinding machine 100. Specifically, the coarse grinding mechanism 20 and the fine grinding mechanism are respectively located on the machine base 10.

[0042] The coarse grinding mechanism 20 has a coarse grinding station 211A, which is used to place stainless steel products. The stainless steel products referred to here are those to be coarsely ground. The fine grinding mechanism has a fine grinding station, which is also used to place stainless steel products. The stainless steel products referred to here are those to be finely ground. It can be understood that when a stainless steel product is placed at the coarse grinding station 211A, the coarse grinding mechanism 20 will then perform a coarse grinding operation on the edges of the stainless steel product located at the coarse grinding station 211A. After the coarse grinding operation is completed, the stainless steel product will be moved to the fine grinding station, where the fine grinding mechanism will then perform a fine grinding operation on the edges of the stainless steel product located at the fine grinding station to meet the requirements for grinding the edges of the stainless steel product.

[0043] The rough grinding mechanism 20 includes a first placement component 21 and a rough grinding component 22. The first placement component 21 is located on the machine base 10 and has a rough grinding station 211A. The rough grinding component 22 includes a base 221 and a rough grinding structure 222. The base 221 is located on the machine base 10 and serves to support the rough grinding structure 222. The rough grinding structure 222 is installed on the base 221 and is used to rough grind the stainless steel products located at the rough grinding station 211A.

[0044] The fine grinding mechanism includes a second placement component and a fine grinding component. The second placement component is located on the machine base 10 and has a fine grinding station. The fine grinding component is located on the machine base 10 and is used to fine grind the edges of the stainless steel product located at the fine grinding station. In actual operation, after the coarse grinding component 22 performs coarse grinding on the stainless steel product located at the coarse grinding station 211A, the stainless steel product is moved to the fine grinding station for fine grinding by the fine grinding component.

[0045] It should be noted that the coarse grinding component 22 and the fine grinding component can grind the same edge of the stainless steel product. That is, after the coarse grinding component 22 grinds the edge, the fine grinding component further grinds the edge to improve the grinding effect. Alternatively, the coarse grinding component 22 and the fine grinding component can be used correspondingly according to the grinding requirements of different edges of the stainless steel product. That is, some edges have lower grinding requirements, so they can be ground by the coarse grinding component 22, and some edges have higher grinding requirements, so they can be ground by the fine grinding component. This embodiment does not specifically limit the grinding method. For ease of understanding, the following explanation uses the example of the coarse grinding component 22 and the fine grinding component grinding the same edge of the stainless steel product. Furthermore, it should be noted that the difference between the fine grinding component and the coarse grinding component 22 is that the diameter of the abrasive particles in the fine grinding component is smaller than the diameter of the abrasive particles in the coarse grinding component 22, thus allowing the effects of coarse grinding and fine grinding to be distinguished after grinding.

[0046] The coarse grinding structure 222 is movable relative to the base 221, allowing it to move under its own weight toward the stainless steel product located at the coarse grinding station 211A until it presses against the edge of the stainless steel product, thereby coarsely grinding the edge of the stainless steel product. It is understood that the movable connection between the coarse grinding structure 222 and the base 221 can be in the form of rotation or sliding, allowing the coarse grinding structure 222 to move relative to the base 221. For example, the coarse grinding structure 222 can move relative to the base 221 along the height direction z under its own weight, moving until it contacts the edge of the stainless steel product to press against the edge. Alternatively, the coarse grinding structure 222 can rotate relative to the base 221 until it contacts the edge of the stainless steel product to press against the edge. This embodiment does not limit this.

[0047] In this embodiment, the coarse grinding structure 222 can move naturally toward the edge of the stainless steel product under its own gravity, and will stop after contacting and pressing against the edge of the stainless steel product, and then start the coarse grinding operation. In this way, no matter which stainless steel product is being coarsely ground, the gravity of the coarse grinding structure 222 can be used to move the coarse grinding structure 222 toward the stainless steel product, and the contact position between the coarse grinding structure 222 and the edge of the stainless steel product is kept as consistent as possible each time. Therefore, when performing subsequent coarse grinding operations, it can be ensured that the edge of the stainless steel product is as uniform in size as possible after coarse grinding, thereby improving the consistency of the stainless steel product output.

[0048] Please refer to the following: Figures 1-3In some embodiments, the coarse grinding assembly 22 further includes a rotating shaft 223, which can be in the form of a rotating shaft 223 and is connected between the coarse grinding structure 222 and the base 221 so that the coarse grinding structure 222 can rotate relative to the base 221 via the rotating shaft 223.

[0049] The coarse grinding structure 222 can rotate under its own weight toward the stainless steel product located at the coarse grinding station 211A until it presses against the edge of the stainless steel product. Specifically, the coarse grinding structure 222 has a length direction, and one side along the length direction is connected to the rotating shaft 223, while the other side is used to coarsely grind the edge of the stainless steel product located at the coarse grinding station 211A. Thus, with the cooperation of one side of the coarse grinding structure 222 along its length direction and the rotating shaft 223, the coarse grinding structure 222 can rotate until the other side of the coarse grinding structure 222 contacts and presses against the edge of the stainless steel product, after which subsequent coarse grinding operations can be performed. Thus, in this embodiment, the coarse grinding structure 222 can move relative to the base 221 by setting the rotating shaft 223, and the structure for achieving rotation is simple and has high smoothness.

[0050] Please refer to the following: Figures 1-3 In some embodiments, the base 221 includes a seat body 2211 and a first driving structure 2212. The seat body 2211 serves to connect the coarse grinding structure 222 and the first driving structure 2212. Specifically, the coarse grinding structure 222 and the first driving structure 2212 are respectively connected to the seat body 2211.

[0051] The first drive structure 2212 is disposed on the machine base 10. The first drive structure 2212 can be a linear module; therefore, when the base 2211 is connected to the first drive structure 2212, the first drive structure 2212 can drive the base 2211 to move linearly. Specifically, the first drive structure 2212 is used to drive the base 2211 to move along a first direction x, so that the rough grinding structure 222 can rough grind the edge of the stainless steel product located at the rough grinding station 211A along the first direction x. The first direction x is parallel to the extending direction of the edge of the stainless steel product located at the rough grinding station 211A.

[0052] 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 first direction x. Based on this, when rough grinding the edges of the stainless steel products, it is necessary to rough grind the entire edge of the stainless steel products. Therefore, under the drive of the first drive structure 2212, the rough grinding structure 222 can move back and forth along the first direction x to rough grind the entire edge of the stainless steel products.

[0053] Of course, this application is not limited to this. In other embodiments, the base 221 and the coarse grinding structure 222 may remain stationary, and the first placement component 21 may reciprocate along the first direction x.

[0054] Please refer to the following: Figures 1-3 In some embodiments, the coarse grinding assembly 22 further includes a limiting member 224 connected to the base 221. The limiting member 224 limits the range of rotation of the coarse grinding structure 222 toward the stainless steel product. It is understood that if the rotation range of the coarse grinding structure 222 is too large, it will cause excessive pressure on the stainless steel product from the other side along its length, resulting in damage to the edge of the stainless steel product.

[0055] Therefore, in this embodiment, the rotation range of the rough grinding structure 222 can be effectively limited by the setting of the limiting member 224, thereby preventing the edge of the stainless steel product from being damaged due to excessive rotation range of the rough grinding structure 222.

[0056] Optionally, the limiting member 224 is a limiting cylinder 2241, which is rotatably connected to the base 221. When the limiting cylinder 2241 limits the rough grinding structure 222, the contact between the limiting cylinder 2241 and the rough grinding structure 222 is a line contact. Thus, through the line contact between the limiting cylinder 2241 and the rough grinding structure 222, when the rough grinding structure 222 and the limiting cylinder 2241 move relative to each other along the extending direction of the limiting cylinder 2241, it helps to reduce the frictional resistance between them and improve the smoothness of movement.

[0057] Please refer to the following: Figures 1-3 Furthermore, the limiting cylinder 2241 includes a cylinder body 2241A and a buffer sleeve 2241B. The cylinder body 2241A is rotatably connected to the base 221. The buffer sleeve 2241B can be made of rubber to provide better cushioning and shock absorption. The buffer sleeve 2241B is fitted onto the cylinder body 2241A.

[0058] Specifically, when the limiting cylinder 2241 limits the coarse grinding structure 222, the contact between the buffer sleeve 2241B and the coarse grinding structure 222 is a line contact. This arrangement allows the buffer sleeve 2241B to provide a cushioning effect for the coarse grinding structure 222, thereby reducing vibration and noise generated by the contact between the coarse grinding structure 222 and the cylinder body 2241A.

[0059] Please refer to the following: Figures 1-3 In some embodiments, the coarse grinding structure 222 includes a coarse grinding element 2221 and a grinding belt structure 2222. The coarse grinding element 2221 has a length direction, and one side of the coarse grinding element 2221 along its length direction is connected to the rotating shaft 223, while the other side is provided with a coarse grinding wheel 2221A.

[0060] A grinding belt structure 2222 is disposed on the coarse grinding part 2221. The grinding belt structure 2222 includes a grinding belt 2222A, a driving member 2222B, a driving wheel 2222C, and a driven wheel 2222D. The grinding belt 2222A has abrasive particles, which rub against the edge of the stainless steel product to achieve coarse grinding of the edge of the stainless steel product. The grinding belt 2222A is wound around the driving wheel 2222C, the driven wheel 2222D, and the coarse grinding wheel 2221A.

[0061] The driving component 2222B can be a drive motor, and the driving component 2222B is connected to the drive wheel 2222C for transmission. It can be understood that under the drive of the driving component 2222B, the drive wheel 2222C can rotate, thereby enabling the abrasive belt 2222A to move around the drive wheel 2222C, the driven wheel 2222D, and the coarse grinding wheel 2221A.

[0062] Therefore, driven by the drive component 2222B, the coarse grinding wheel 2221A can cooperate with the abrasive belt 2222A to coarsely grind the edge of the stainless steel product. In this way, the position of friction between the abrasive belt 2222A and the edge of the stainless steel product can be changed, avoiding long-term friction on one area of ​​the abrasive belt 2222A, thus ensuring the friction effect while extending the service life of the abrasive belt 2222A. Simultaneously, the driven wheel 2222D can act as a tensioning wheel, providing tension to the abrasive belt 2222A to prevent it from becoming loose, thereby ensuring the friction effect between the abrasive belt 2222A and the edge of the stainless steel product.

[0063] Because some processed stainless steel products have a square structure, they have four edges that connect end to end, and all four edges need to be rough ground. Therefore, please refer to [the relevant documentation / reference needed]. Figures 1-3 In some embodiments, the base 221 further includes a second driving structure 2213, which can be a linear module.

[0064] Specifically, the second drive structure 2213 is connected to the base 2211 to drive the base 2211 to move along the second direction y, which is perpendicular to the first direction x. The first drive structure 2212 is connected to the second drive structure 2213 to drive the base 2211 to move along the first direction x. It can be understood that after the rough grinding structure 222 has finished rough grinding one edge of the stainless steel product, it needs to rough grind the other edge. At this time, the second drive structure 2213 can drive the base 2211 to move along the second direction y to move away from the placement table 211, thereby avoiding interference with the rotation of the stainless steel product. Then, the stainless steel product can be rotated, and after rotation, the second drive structure 2213 can drive the base 2211 to move along the second direction y to move closer to the placement table 211, thereby rough grinding the other edge.

[0065] To further enhance the automation level of the rough grinding mechanism 20, in this embodiment, the first placement component 21 includes a placement table 211 and a rotary table 212. The placement table 211 has a rough grinding station 211A and is mounted on the rotary table 212. The rotary table 212 is located on the machine base 10 and can drive 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 rough grinding structure 222.

[0066] 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 first driving structure 2212 and to the second driving structure 2213, wherein the third driving structure 2214 is used to drive the second driving structure 2213 to move along the height direction z, thereby causing the seat 2211 to move along the height direction z.

[0067] Understandably, in some scenarios, it is necessary to rough 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 adaptive adjustments. Alternatively, in other scenarios, when it is necessary to change the style of stainless steel products for rough 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 adaptive adjustments.

[0068] In some exemplary working processes, the stainless steel product can first be placed on the rough grinding station 211A of the placement table 211. Then, the rough grinding part 2221 of the rough grinding structure 222 rotates under its own weight to move towards the stainless steel product located at the rough grinding station 211A until it contacts the edge of the stainless steel product. Then, driven by the drive member 2222B, the rough grinding wheel 2221A can cooperate with the abrasive belt 2222A to rough grind one edge of the stainless steel product. Under the drive of the first drive structure 2212, the seat 2211 can drive the rough grinding structure 222 to reciprocate along the first direction x to rough grind the entire edge. After completion, the second drive structure 2213 will drive the seat 2211 away from the placement table 211. Then, the rotary table 212 will drive the placement table 211 to move along the second direction y to adjust the position of the stainless steel product relative to the coarse grinding structure 222. After the adjustment is completed, the second drive structure 2213 will drive the seat 2211 closer to the placement table 211 to coarsely grind the other edge of the stainless steel product until the coarse grinding is completed. After the coarse grinding is completed, the stainless steel product is transferred to the fine grinding station of the second placement component to finely grind multiple edges of the stainless steel product through the fine grinding component. After the fine grinding is completed, the edge grinding work of the stainless steel product is completed.
