Description

Technical Field

[0001] This invention belongs to the field of other metal processing machinery manufacturing technology, specifically a grinding device for processing stainless steel screws. Background Technology

[0002] Stainless steel screws are common fasteners widely used in machinery, electrical appliances, construction, and other fields. They are generally made of metal, cylindrical in shape, with threads on the surface, and possess the ability to resist corrosion from various media. They are not easily rusted and are durable, making them suitable for use in environmental protection, medical, and communication equipment. In the screw manufacturing process, to ensure the quality of their end faces, grinding equipment is typically used to grind the screw ends.

[0003] A patent with publication number CN214445092U discloses a grinding device for processing stainless steel screws, including a protective shell, a telescopic push rod, a first motor, a three-jaw chuck, a screw body, a second motor, and a grinding device body. The inner wall of the protective shell has a sliding groove, and the telescopic push rod is fixed to the bottom of the fixed plate. The output shaft of the first motor is connected to a rolling shaft via a coupling, and the three-jaw chuck is fixed to the outer wall of the rolling shaft. This grinding device for processing stainless steel screws, through the first motor, allows the user to rotate the three-jaw chuck, thereby rotating the screw body and allowing the user to grind the entire diameter of the stainless steel screw.

[0004] The above-mentioned solution still has some problems in practical application. First, the existing grinding device can only grind a single screw at a time. In mass production, it will consume a lot of time and cannot meet the needs of large-scale production, resulting in low grinding efficiency. In addition, the edge of the screw tip also needs to be ground during the grinding process. However, when grinding the edge of the screw tip, the existing grinding device only fixes the screw, grinds one edge, and then gradually adjusts the screw angle to grind each edge of the screw tip. This grinding process is cumbersome, and the grinding quality will also decrease under long working hours, which will affect work efficiency and result in low screw production efficiency.

[0005] Therefore, the present invention provides a grinding device for processing stainless steel screws. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: A grinding device for processing stainless steel screws according to the present invention includes a machine body, a fixed motor is fixedly connected to one end of the machine body, the fixed motor is driven by a drive shaft, a rotating disk is fixedly connected to the bottom end of the drive shaft, a positioning disk is arranged below the rotating disk, the positioning disk is fixedly connected to the machine body through a positioning frame fixedly connected to one side, a fixing component is arranged inside the positioning disk, the fixing component includes a plurality of fixing disks rotatably arranged inside the positioning disk, a fixing groove is opened in the fixing disk, and a screw body is locked in each fixing groove;

[0008] The positioning disk is also equipped with a rotating assembly, which includes a motor fixedly connected to the bottom of the machine body. The output end of the motor passes through the positioning disk and is fixedly connected to an auxiliary disk. A gear disk is fixedly connected to the lower surface of the auxiliary disk. A fixed gear is fixedly connected to the lower surface of each fixed disk. The fixed gear meshes with the gear disk. A toothed ring is also fixedly connected to the inner wall of the positioning disk. The toothed ring meshes with several fixed gears.

[0009] Preferably, the inner wall of the rotating disk is made of frosted material, and a rotating ring is fixed to the lower surface of the rotating disk. The rotating ring is used to polish the edges of the screw ends.

[0010] Preferably, the upper surface of the rotating disk has a slot, and the machine body sprays coolant at the slot. The upper surface of the rotating disk has an annular groove, and the bottom surface of the annular groove has several fixing holes. The surface of the auxiliary disk has several inclined grooves, which are used to guide cutting oil.

[0011] Preferably, when grinding the screw body, the screw body is first inserted one by one into the fixing slot in the fixing plate. The fixing motor is started to drive the rotating plate to rotate. While the rotating plate rotates, it drives the rotating ring to rotate, grinding the upper surface and edges of the screw body. At the same time, the motor below the machine body drives the auxiliary plate to rotate, which drives the gear plate to rotate. The rotation of the gear plate drives the fixed gear to rotate along the toothed ring on the inner wall of the positioning plate. Each fixed gear will drive the fixing plate fixed to its upper surface to rotate, grinding each edge of the screw body.

[0012] Preferably, a guide frame is fixedly connected to one side of the machine body, a fixed platform is fixedly connected to one side of the guide frame, a first hydraulic cylinder is fixedly connected to the upper surface of the fixed platform, a disassembly assembly is provided at the output end of the first hydraulic cylinder, the disassembly assembly includes a connecting plate fixedly connected to the output end of the first hydraulic cylinder, a fixed frame is fixedly connected to the end of the connecting plate, and an auxiliary frame is fixedly connected to the lower surface of the fixed frame. The auxiliary frame is used for disassembling the screw body after grinding.

[0013] Preferably, the auxiliary frame has an auxiliary groove inside, the cross-section of which is larger than the cross-section of the screw body end. The bottom of the auxiliary frame has symmetrically arranged limiting grooves. A spring is fixedly connected in the limiting groove. A limiting block is fixedly connected to one end of the spring. Several rubber strips are fixedly connected to one side of the limiting block.

[0014] Preferably, after the screw body in the positioning plate is polished, the slot of the rotating plate is aligned with the auxiliary frame by rotating the rotating plate. At this time, the auxiliary frame moves downward under the drive of the first hydraulic cylinder. The auxiliary frame will cover the top of the screw body, and the two limit blocks will engage with the screw body. Under the action of the two springs, the limit blocks will hold the screw body in place. Then the next screw is disassembled. The disassembled screw will accumulate along the auxiliary groove until it overflows from the top of the auxiliary groove. At this time, the screw body will fall into the prepared collection box along the fixed frame.

[0015] Preferably, a filling assembly is provided on one side of the machine body. The filling assembly includes a positioning box fixed to one side of the machine body. A limiting frame is fixed inside the positioning box. A compression spring is fixed to the top wall of the limiting frame. A stop plate is fixed to the bottom end of the compression spring. A rotating plate is rotatably connected to one side of the limiting frame. A torsion spring is provided inside the rotating plate and is fixed to the limiting frame. An auxiliary hole is opened on the top of the positioning box. The rotating plate seals the auxiliary hole. A storage box is fixed to the upper surface of the positioning box. The storage box communicates with the positioning box through the auxiliary hole. A sealing cover is threaded to the upper surface of the storage box. A push plate is fixed to one side of the fixing frame. Several fixing tubes are fixed to the lower surface of the positioning box.

[0016] Preferably, when adding cutting oil to the annular groove on the upper surface of the rotating disk, the first hydraulic cylinder is activated to push the fixed frame upward, which in turn pushes the push plate on one side of the fixed frame upward. When the push plate moves to the top, it pushes the abutment plate upward. The upward movement of the abutment plate causes the rotating plate to rotate. After the rotating plate rotates, the seal on the storage box is released, and the cutting oil in the storage box flows into the positioning box through the auxiliary hole. Then it flows from the fixed pipe into the annular groove, and then flows along the fixed hole on the annular groove to the inclined groove to lubricate the fixed gear and gear disk and carry away the metal dust accumulated inside. Finally, it flows out from the hole on the lower surface of the positioning disk.

[0017] Preferably, a fixing port is provided on one side of the guide frame, and a connecting pipe is fixedly connected to the guide frame at the fixing port. An auxiliary frame is provided on one side of the machine body, and several inclined plates are fixedly connected to the upper surface of the auxiliary frame. A filter plate is fixedly connected between the inclined plates, and one end of the connecting pipe is located directly above the filter plate for filtering the outflowing cutting oil and coolant.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The present invention discloses a grinding device for processing stainless steel screws. By setting up several fixed discs to fix the screw body, the end faces and edges of several screw bodies are ground simultaneously, which improves the grinding efficiency. In addition, the periodic spraying of cutting oil and coolant lubricates and washes the rotating disc, rotating ring and fixed gear and other components, extending the service life of the equipment and indirectly improving the screw processing efficiency and quality, thus solving the problem of low grinding efficiency in the prior art.

[0020] 2. The stainless steel screw grinding equipment of the present invention, after the screw body in the positioning plate is ground, rotates the rotating plate to align its slot with the auxiliary frame. At this time, the auxiliary frame moves downward under the drive of the first hydraulic cylinder, and the auxiliary frame covers the top of the screw body. Two limiting blocks engage with the screw body. Under the action of two springs, the limiting blocks hold the screw body in place. Then the next screw is disassembled. The disassembled screws accumulate along the auxiliary groove until they overflow from the top of the auxiliary groove. At this time, the screw body falls into the prepared collection box along the fixed frame, achieving the effect of automatic disassembly, improving the grinding efficiency of the screw body, greatly reducing the disassembly time of the screw body, and reducing labor costs.

[0021] 3. The stainless steel screw grinding equipment of the present invention automatically adds cutting oil by activating the first hydraulic cylinder to move the fixed frame upward, which in turn moves the push plate on one side of the fixed frame upward. When the auxiliary frame is higher than the rotating disk, the push plate continues to move upward, which in turn moves the abutment plate upward. The upward movement of the abutment plate causes the rotating plate to rotate. After the rotating plate rotates, the seal on the storage box is released, and the cutting oil in the storage box flows into the positioning box through the auxiliary hole. Then it flows from the fixed pipe into the annular groove, and then along the fixed hole on the annular groove into the inclined groove to lubricate the fixed gear and gear disk and remove the metal dust accumulated inside. Then it flows out from the hole on the lower surface of the positioning disk. After the oil is added, the connecting plate is retracted, but the auxiliary frame must be higher than the rotating disk to avoid affecting the rotation of the rotating disk. In the subsequent disassembly work, the auxiliary frame is lowered to carry out the disassembly work. This achieves the effect of automatic adding of cutting oil, saves processing costs, improves grinding efficiency, and eliminates the need for manual oil addition. Attached Figure Description

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1: As Figures 1 to 8As shown in the embodiment of the present invention, a grinding device for processing stainless steel screws includes a body 1. A fixed motor 2 is fixedly connected to one end of the body 1. The fixed motor 2 is driven by a drive shaft 21. A rotating disk 22 is fixedly connected to the bottom end of the drive shaft 21. The inner wall of the rotating disk 22 is made of frosted material. A rotating ring 23 is fixedly connected to the lower surface of the rotating disk 22. The rotating ring 23 is used to grind the edge of the screw end. A groove 24 is opened on the upper surface of the rotating disk 22. The body 1 sprays coolant at the groove 24. An annular groove 25 is opened on the upper surface of the rotating disk 22. A plurality of fixing holes 26 are opened on the bottom surface of the annular groove 25. A plurality of inclined grooves 212 are opened on the surface of the auxiliary disk 211. The inclined grooves 212 are used to guide cutting oil.

[0037] A positioning disk 27 is provided below the rotating disk 22. The positioning disk 27 is fixed to the machine body 1 through a positioning frame 216 fixed on one side. A fixing component is provided inside the positioning disk 27. The fixing component includes several fixing disks 28 rotatably disposed inside the positioning disk 27. Fixing grooves 29 are opened in the fixing disks 28, and screw bodies 210 are engaged in each fixing groove 29. A rotating component is also provided inside the positioning disk 27. The rotating component includes a motor fixed to the bottom of the machine body 1. The output end of the motor passes through the positioning disk 27 and is fixed to an auxiliary disk 211. A gear disk 213 is fixed to the lower surface of the auxiliary disk 211. A fixed gear 214 is fixed to the lower surface of each fixing disk 28. The fixed gear 214 meshes with the gear disk 213. A toothed ring 215 is also fixed to the inner wall of the positioning disk 27. The toothed ring 215 meshes with several fixed gears 214.

[0038] Specifically, existing grinding equipment can only grind a single screw at a time. In mass production, this consumes a lot of time and is difficult to meet the needs of large-scale production, resulting in low grinding efficiency. In addition, the edges of the screw tip also need to be ground during the grinding process. However, when grinding the edges of the screw tip, the existing grinding equipment simply fixes the screw, grinds one edge, and then gradually adjusts the screw angle to grind each edge of the screw tip. This grinding process is cumbersome, and the grinding quality will also decrease under long working hours, which will affect work efficiency and result in low screw production efficiency.

[0039] Therefore, the present invention solves the above problems by setting up the above structure. First, when grinding the screw body 210, the screw body 210 is inserted one by one into the fixing slot 29 in the fixing plate 28. By rotating the rotating plate 22, the position of the slot 24 is changed, so that the screw body 210 is inserted into each fixing slot 29. Then, the fixing motor 2 is started again to drive the rotating plate 22 to rotate. While the rotating plate 22 rotates, it drives the rotating ring 23 to rotate, and grinds the upper surface and edges of the screw body 210. At the same time, the motor driving the auxiliary plate 211 below the machine body 1 rotates, which drives the gear plate 213 to rotate. The rotation of the gear plate 213 drives the fixed gear 214 to rotate along the toothed ring 215 on the inner wall of the positioning plate 27. Each fixed gear 214 will drive the fixing plate 28 fixed to its upper surface to rotate, and grind each edge of the screw body 210.

[0040] During the grinding process, the external coolant spray nozzle will be aimed at the slot 24 opened on the upper surface of the rotating disk 22 to periodically spray coolant. Because the fixed motor 2 drives the rotating disk 22 to rotate, the slot 24 will rotate, and thus periodically spray. This not only washes away the heat generated by the rotating disk 22 during the grinding process, but also solves the coolant problem. At the same time, there will also be cutting oil in the annular groove 25 on the upper surface of the rotating disk 22. The cutting oil flows into the rotating disk 22 and the positioning disk 27 along the inclined groove 212 on the upper surface of the auxiliary disk 211, and washes away the metal dust remaining between the fixed gear 214, the gear disk 213 and the tooth ring 215 to prevent it from affecting the normal operation of the fixed gear 214.

[0041] By setting up several fixed discs 28 to fix the screw body 210, the end faces and edges of several screw bodies 210 are simultaneously ground, which improves the grinding efficiency. In addition, the periodic spraying of cutting oil and coolant lubricates and washes the rotating disc 22, rotating ring 23 and fixed gear 214 and other parts, extending the service life of the equipment and indirectly improving the screw processing efficiency and quality, thus solving the problem of low grinding efficiency in the existing technology.

[0042] like Figure 1 , Figure 6 and Figure 7 As shown, in this embodiment, a guide frame 35 is fixedly connected to one side of the machine body 1, a fixed platform 4 is fixedly connected to one side of the guide frame 35, a first hydraulic cylinder 41 is fixedly connected to the upper surface of the fixed platform 4, a disassembly assembly is provided at the output end of the first hydraulic cylinder 41, the disassembly assembly includes a connecting plate 45 fixedly connected to the output end of the first hydraulic cylinder 41, a fixed frame 42 is fixedly connected to the end of the connecting plate 45, an auxiliary frame 46 is fixedly connected to the lower surface of the fixed frame 42, and the auxiliary frame 46 is used for disassembling the screw body 210 after grinding.

[0043] The auxiliary frame 46 has an auxiliary groove 47 inside. The cross-section of the auxiliary groove 47 is larger than the cross-section of the end of the screw body 210. The bottom of the auxiliary frame 46 has a symmetrically arranged limiting groove 414. A spring 415 is fixedly connected in the limiting groove 414. One end of the spring 415 is fixedly connected to a limiting block 416. Several rubber strips 417 are fixedly connected to one side of the limiting block 416.

[0044] Specifically, after the screw body 210 in the positioning plate 27 is polished, the slot 24 of the rotating plate 22 is aligned with the auxiliary frame 46 by rotating the rotating plate 22. At this time, the auxiliary frame 46 moves downward under the drive of the first hydraulic cylinder 41, and the auxiliary frame 46 covers the top of the screw body 210. The two limiting blocks 416 engage the screw body 210. Under the action of the two springs 415, the limiting blocks 416 hold the screw body 210 in place. Then, the next screw is disassembled. The disassembled screws accumulate along the auxiliary groove 47 until they overflow from the top of the auxiliary groove 47. At this time, the screw body 210 falls into the prepared collection box along the fixing frame 42, achieving the effect of automatic disassembly. This improves the polishing efficiency of the screw body 210, greatly reduces the disassembly time of the screw body 210, and reduces labor costs.

[0045] Example 2: Figures 1 to 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: A filling assembly is provided on one side of the body 1. The filling assembly includes a positioning box 43 fixedly connected to one side of the body 1. A limiting frame 411 is fixedly connected inside the positioning box 43. A compression spring 410 is fixedly connected to the top wall of the limiting frame 411. A stop plate 49 is fixedly connected to the bottom end of the compression spring 410. A rotating plate 419 is rotatably connected to one side of the limiting frame 411. A torsion spring 420 is provided inside the rotating plate 419. The torsion spring 420 is fixedly connected to the limiting frame 411. An auxiliary hole 418 is opened on the top of the positioning box 43. The rotating plate 419 seals the auxiliary hole 418. A storage box 44 is fixedly connected to the upper surface of the positioning box 43. The storage box 44 communicates with the positioning box 43 through the auxiliary hole 418. A sealing cover 413 is threadedly connected to the upper surface of the storage box 44. A push plate 48 is fixedly connected to one side of the fixing frame 42. Several fixing tubes 412 are fixedly connected to the lower surface of the positioning box 43.

[0046] Specifically, when cutting oil is added to the annular groove 25 on the upper surface of the rotating disk 22, the first hydraulic cylinder 41 is activated to push the fixed frame 42 upward, which in turn pushes the push plate 48 on one side of the fixed frame 42 upward. When the auxiliary frame 46 is higher than the rotating disk 22, the push plate 48 continues to move upward, which pushes the abutment plate 49 upward. The upward movement of the abutment plate 49 pushes the rotating plate 419 to rotate. After the rotating plate 419 rotates, the seal on the storage box 44 is released, and the cutting oil in the storage box 44 flows into the positioning box 43 along the auxiliary hole 418, and then flows out from the fixed pipe 4 The oil flows into the annular groove 25, then along the fixing hole 26 on the annular groove 25 to the inclined groove 212, lubricating the fixed gear 214 and gear disk 213 and carrying away the metal dust accumulated inside. Then it flows out from the hole on the lower surface of the positioning disk 27. After the oil is added, the connecting plate 45 is retracted, but the auxiliary frame 46 should be higher than the rotating disk 22 so as not to affect the rotation of the rotating disk 22. In the subsequent disassembly work, the auxiliary frame 46 is lowered to carry out the disassembly work, which achieves the effect of automatic oil addition, saves processing costs, improves grinding efficiency, and eliminates the need for manual oil addition.

[0047] like Figure 1 As shown, in this embodiment, a fixing port 34 is provided on one side of the guide frame 35, and a connecting pipe 33 is fixedly connected to the guide frame 35 at the fixing port 34. An auxiliary frame 3 is provided on one side of the machine body 1. Several inclined plates 31 are fixedly connected to the upper surface of the auxiliary frame 3, and filter plates 32 are fixedly connected between the inclined plates 31. One end of the connecting pipe 33 is located directly above the filter plate 32 and is used to filter the outflowing cutting oil and coolant.

[0048] Specifically, the cutting oil and coolant generated during the grinding process of the screw body 210 flow out through the fixed port 34 on one side of the guide frame 35 and are guided to the auxiliary frame 3 on one side of the machine body 1 through the corresponding fixed connecting pipe 33. The auxiliary frame 3 is provided with several inclined plates 31, and filter plates 32 are fixed between the inclined plates 31. One end of the connecting pipe 33 is located directly above the filter plate 32. When the cutting oil and coolant flow through this point, the filter plate 32 plays a filtering role, trapping metal dust and debris, effectively removing impurities from the cutting oil and coolant, ensuring its purity, extending the service life of the oil, and reducing the cost of use; at the same time, the filtered oil can better play its cooling and lubrication role, improving the processing quality and efficiency.

[0049] Working principle: First, when grinding the screw body 210, the screw body 210 is inserted one by one into the fixing slot 29 in the fixing plate 28. By rotating the rotating plate 22, the position of the slot 24 is changed, so that the screw body 210 is inserted into each fixing slot 29. Then, the fixing motor 2 is started again to drive the rotating plate 22 to rotate. While the rotating plate 22 rotates, it drives the rotating ring 23 to rotate, grinding the upper surface and edges of the screw body 210. At the same time, the motor below the machine body 1 drives the auxiliary plate 211 to rotate, driving the gear plate 213 to rotate. The rotation of the gear plate 213 drives the fixed gear 214 to rotate along the toothed ring 215 on the inner wall of the positioning plate 27. Each fixed gear 214 will drive the fixing plate 28 fixed to its upper surface to rotate, grinding each edge of the screw body 210.

[0050] During the grinding process, the external coolant spray nozzle will be aimed at the slot 24 opened on the upper surface of the rotating disk 22 to periodically spray coolant. Because the fixed motor 2 drives the rotating disk 22 to rotate, the slot 24 will rotate, and thus periodically spray. This not only washes away the heat generated by the rotating disk 22 during the grinding process, but also solves the coolant problem. At the same time, there will also be cutting oil in the annular groove 25 on the upper surface of the rotating disk 22. The cutting oil flows into the rotating disk 22 and the positioning disk 27 along the inclined groove 212 on the upper surface of the auxiliary disk 211, and washes away the metal dust remaining between the fixed gear 214, the gear disk 213 and the tooth ring 215 to prevent it from affecting the normal operation of the fixed gear 214.

[0051] By setting up several fixed discs 28 to fix the screw body 210, the end faces and edges of several screw bodies 210 are simultaneously ground, which improves the grinding efficiency. In addition, the periodic spraying of cutting oil and coolant lubricates and washes the rotating disc 22, rotating ring 23 and fixed gear 214 and other parts, extending the service life of the equipment and indirectly improving the screw processing efficiency and quality, thus solving the problem of low grinding efficiency in the existing technology.

[0052] After the screw body 210 in the positioning plate 27 is polished, the slot 24 of the rotating plate 22 is aligned with the auxiliary frame 46 by rotating the rotating plate 22. At this time, the auxiliary frame 46 moves downward under the drive of the first hydraulic cylinder 41, and the auxiliary frame 46 covers the top of the screw body 210. The two limit blocks 416 will lock the screw body 210. Under the action of the two springs 415, the limit blocks 416 lock the screw body 210, and then the next screw is disassembled. The disassembled screw will accumulate along the auxiliary groove 47 until it overflows from the top of the auxiliary groove 47. At this time, the screw body 210 will fall into the prepared collection box along the fixed frame 42, achieving the effect of automatic disassembly, improving the polishing efficiency of the screw body 210, greatly reducing the disassembly time of the screw body 210, and reducing labor costs.

[0053] Additionally, when cutting oil is added to the annular groove 25 on the upper surface of the rotating disk 22, the first hydraulic cylinder 41 is activated to push the fixed frame 42 upward, which in turn pushes the push plate 48 on one side of the fixed frame 42 upward. When the auxiliary frame 46 is higher than the rotating disk 22, the push plate 48 continues to move upward, which pushes the abutment plate 49 upward. The upward movement of the abutment plate 49 causes the rotating plate 419 to rotate. After the rotating plate 419 rotates, the seal on the storage box 44 is released, and the cutting oil in the storage box 44 flows into the positioning box 43 along the auxiliary hole 418, and then flows out from the fixed pipe 41. 2. The oil flows into the annular groove 25, and then along the fixing hole 26 on the annular groove 25 to the inclined groove 212, lubricating the fixed gear 214 and gear disk 213 and carrying away the metal dust accumulated inside. Then it flows out from the hole on the lower surface of the positioning disk 27. After the oil is added, the connecting plate 45 is retracted, but the auxiliary frame 46 should be higher than the rotating disk 22 so as not to affect the rotation of the rotating disk 22. In the subsequent disassembly work, the auxiliary frame 46 is lowered to carry out the disassembly work, which achieves the effect of automatic oil addition, saves processing costs, improves grinding efficiency, and eliminates the need for manual oil addition.

[0054] Finally, the cutting oil and coolant generated during the grinding process of the screw body 210 flow out through the fixed port 34 on one side of the guide frame 35 and are guided to the auxiliary frame 3 on one side of the machine body 1 through the corresponding fixed connecting pipe 33. The auxiliary frame 3 is provided with several inclined plates 31, and filter plates 32 are fixed between the inclined plates 31. One end of the connecting pipe 33 is located directly above the filter plate 32. When the cutting oil and coolant flow through this point, the filter plate 32 plays a filtering role, trapping metal dust and debris, effectively removing impurities from the cutting oil and coolant, ensuring its purity, extending the service life of the oil, and reducing the cost of use; at the same time, the filtered oil can better play its cooling and lubrication role, improving the processing quality and efficiency.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
