Description

Technical Field

[0001] The invention belongs to the field of stainless steel cutting equipment, in particular to a stainless steel basin inner surface grinding device. Background Art

[0002] The main purpose of grinding stainless steel basins during processing is to remove scratches, pits, oxide layers, and other surface defects on their inner surfaces. The grinding process also improves the surface roughness from an initially rough state to a smoother state, thereby improving surface quality, enhancing corrosion resistance, and enhancing overall aesthetics. The specific grinding process involves the multi-axis motion of the grinding device approaching the stainless steel basin while the basin itself rotates, causing the grinding tool to contact the inner surface of the basin and apply a certain cutting force, thereby achieving the grinding operation.

[0003] A patent document with publication number CN207578045U discloses a stainless steel inner tube grinding device, including a base plate, a telescopic plate, an air pump, a grinding block and a second servo motor.

[0004] In traditional technical solutions, the grinding tool contacts the inner surface of a rotating stainless steel hollow basin and performs the grinding operation under the condition of applying a certain cutting force.

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

[0019] 1.

The stainless steel basin inner surface grinding equipment described in the present invention has the other half of the debris thrown out toward a group of corresponding arc-shaped guide grooves and arc-shaped partitions due to centrifugal force, which will stick to the arc-shaped partitions. With the existence of centrifugal force, this part of the debris moves on one side of the arc-shaped partition until it is released from the nearest strip discharge trough.

[0021] 3.

As the grinding assembly moves, the strip grinding belt contacts the inner surface of the hollow basin to achieve grinding. The setting of the triangular block can make the smaller part of the strip grinding belt on the outside of the triangular block contact the inner surface of the hollow basin. As the grinding assembly moves away from the hollow basin, the smaller part of the strip grinding belt on the outside of the triangular block grinds the inner surface of the hollow basin, avoiding damage to the strip grinding belt caused by excessive parts of the strip grinding belt contacting the inner surface of the hollow basin, thereby affecting the grinding efficiency.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] Example 1: Figure 1-5As shown, a stainless steel basin inner surface grinding device according to an embodiment of the present invention includes a base 1 and a multi-axis moving assembly 2 fixedly mounted on one side above the base 1, a working platform 3 fixedly mounted above the multi-axis moving assembly 2, a grinding assembly 4 fixedly mounted above the working platform 3, a driving assembly 5 fixedly mounted on the other side above the base 1, and a component cylinder 6 is connected to the driving assembly 5 on the side facing the working platform 3 through an axis, a hollow basin body 7 is placed inside the component cylinder 6, and a gap exists between the hollow basin body 7 and the component cylinder 6 in the vertical direction;

[0035] A plurality of strip discharge grooves 61 are provided through the interior of the component cylinder 6, and the plurality of strip discharge grooves 61 are evenly distributed on the component cylinder 6. A plurality of arc-shaped guide grooves 62 are also provided inside the component cylinder 6, and one arc-shaped guide groove 62 is connected to two corresponding adjacent strip discharge grooves 61. The distance between the inner wall of one end of the arc-shaped guide groove 62 and the center of the component cylinder 6 is smaller than the distance between the inner wall of the other end of the arc-shaped guide groove 62 and the center of the component cylinder 6.

[0036] Specifically, when it is necessary to grind the inner surface of the hollow basin body 7, the hollow basin body 7 is first placed inside the component tube 6 and locked tightly. At this time, there is a gap between the vertical surface of the hollow basin body 7 inside the component tube 6 and the inner wall of the component tube 6. At this time, when the driving component 5 is driven, the component tube 6 connected to the driving component 5 through the shaft will rotate at high speed. At this time, the grinding component 4 is driven by the working platform 3 to perform multi-axis movement, so that the end grinding part of the grinding component 4 contacts the center position of the hollow basin body 7, and then performs horizontal displacement. In this process, the grinding part of the grinding component 4 is in contact with the inner surface of the high-speed rotating hollow basin body 7. The contact part is ground. As the hollow basin body 7 continues to rotate, the working platform 3 drives the grinding assembly 4 to gradually move away from the hollow basin body 7, and at this time, the grinding part of the grinding assembly 4 contacts the inner surface of the ring of the hollow basin body 7, and then grinds it. Due to the hollow setting of the hollow basin body 7, a plurality of slots are opened inside it. The debris generated during the grinding process may be blocked or attached to the hollow slots of the hollow basin body 7, which will cause the hollow basin body 7 to need to be cleaned after the grinding work is completed. At this time, a plurality of strip discharge troughs 61 are opened inside the component cylinder 6. When the inner surface of the hollow basin body 7 is ground, the component cylinder 6 and the hollow The hollow basin body 7 rotates at high speed, thereby generating centrifugal force so that the debris will enter the gap between the hollow basin body 7 and the component cylinder 6 through the hollow slots of the hollow basin body 7, until the debris is thrown out to the outside through multiple strip discharge grooves 61. In this device, multiple arc-shaped guide grooves 62 are also provided inside the component cylinder 6, and the two ends of the arc-shaped guide grooves 62 are connected to two adjacent strip discharge grooves 61, and the distance between the inner wall of one end of the arc-shaped guide groove 62 and the center of the component cylinder 6 is smaller than the distance between the inner wall of the other end of the arc-shaped guide groove 62 and the center of the component cylinder 6. The distance between the inner wall of the arc-shaped guide groove 62 and the center of the component cylinder 6 is gradual. As the component cylinder 6 and the hollow basin body 7 rotate away With the emergence of centrifugal force, the grinding debris will be thrown toward the inner wall of the component tube 6, that is, into the inside of the arc-shaped guide groove 62. Due to the gradual setting of the distance between the inner wall of the arc-shaped guide groove 62 and the middle of the component tube 6, the grinding debris will be better moved from the arc-shaped guide groove 62 until the debris moves to the end with a larger distance between the arc-shaped guide groove 62 and the center of the component tube 6, and then discharged from the strip discharge groove 61 connected to this end of the arc-shaped guide groove 62, so that the debris generated by grinding will not adhere to and clog the inner surface of the hollow basin body 7, thereby avoiding subsequent cleaning steps. The gradual direction of the distance between the arc-shaped guide groove 62 and the center of the component tube 6 from small to large is consistent with the rotation direction of the component tube 6.

[0037] like Figure 2-4As shown, the driving assembly 5 includes a driving box 51 fixedly mounted above the base 1, and a driving motor 52 is fixedly mounted on the side of the driving box 51. The driving motor 52 drives the component tube 6 to rotate, and a circular ear 71 is fixedly mounted on the side of the hollow basin body 7. The diameter of the circular ear 71 is larger than the outer diameter of the component tube 6, and the diameter of the hollow part of the hollow basin body 7 is smaller than the inner diameter of the component tube 6.

[0038] A plurality of arc-shaped partitions 63 are fixedly installed inside the component tube 6, and the plurality of arc-shaped partitions 63 are evenly distributed inside the component tube 6. The arc-shaped partitions 63 cover the outer side of one end of the arc-shaped guide groove 62. The distance between the arc-shaped guide groove 62 and the arc-shaped partitions 63 is used for the passage of grinding waste. The arc length of the arc-shaped partitions 63 is smaller than the arc length of the arc-shaped guide groove 62.

[0039] Specifically, the arc guide groove 62 is connected to two adjacent strip discharge grooves 61, and the arc length of the arc partition 63 is half of the arc guide groove 62. One side of the arc partition 63 is connected to the adjacent strip discharge groove 61. At this time, there will be a certain distance between the arc partition 63 and the arc guide groove 62. At this time, half of the debris thrown out from the hollow slot of the hollow basin body 7 toward a group of corresponding arc guide grooves 62 and arc partitions 63 due to centrifugal force will stick to the inner wall of the arc guide groove 62. Due to the gradual setting of the arc guide groove 62, as the centrifugal force continues to exist, this part The debris moves on the inner wall of the arc guide groove 62, and is released from the adjacent strip discharge groove 61 through the gap between the arc guide groove 62 and the arc partition 63, while the other half of the debris will stick to the arc partition 63. With the existence of centrifugal force, this part of the debris moves on one side of the arc partition 63 until it is released from the nearest strip discharge groove 61. The existence of the arc partition 63 can divide the amount of debris thrown toward a group of corresponding arc guide grooves 62 and arc partitions 63, avoiding excessive debris movement, reducing the debris movement rate, and accelerating the grinding of the inner surface of the stainless steel basin.

[0040] like Figure 6-7 As shown, the grinding assembly 4 includes a fixed column 41 fixedly installed above the working platform 3, and a triangular block 411 is fixedly installed on the middle side of one end of the fixed column 41 facing the hollow basin 7, and a strip grinding belt 42 is sleeved on the middle of the fixed column 41 and the outer side of the triangular block 411.

[0041] Two winding wheels 31 and two guide wheels 32 are movably mounted on one side of the upper end of the working platform 3 . The two winding wheels 31 are used for winding and unwinding the strip-shaped sanding belt 42 . The outer sides of the two guide wheels 32 are in contact with the strip-shaped sanding belt 42 .

[0042] Two telescopic components 33 are fixedly installed above the working platform 3. The two telescopic components 33 are located on both sides of the fixed column 41. A displacement bar 331 is movably installed on one side of the telescopic component 33 facing the fixed column 41. The two displacement bars 331 are used to clamp the strip sanding belt 42.

[0043] Specifically, the strip sanding belt 42 is attached to the middle of the fixed column 41 and the outside of the triangular block 411. The movement of the working platform 3 drives the end of the grinding assembly 4 to move toward the rotating hollow basin 7. At this time, the telescopic assembly 33 drives the displacement bar 331 to move toward the direction of the grinding assembly 4 until the two displacement bars 331 are against the outside of the strip sanding belt 42, so that the strip sanding belt 42 at the end of the fixed column 41 and the outside of the triangular block 411 is in a taut state. As the grinding assembly 4 moves, until the strip sanding belt 42 contacts the inner surface of the hollow basin 7 to realize the grinding work, the triangular block 4 The setting of 11 can make the smaller part of the strip grinding belt 42 on the outside of the triangular block 411 contact the inner surface of the hollow basin body 7. As the grinding component 4 moves away from the hollow basin body 7, the smaller part of the strip grinding belt 42 on the outside of the triangular block 411 grinds the inner surface of the hollow basin body 7, avoiding excessive contact of the strip grinding belt 42 with the inner surface of the hollow basin body 7, thereby causing damage to the strip grinding belt 42 and affecting the grinding efficiency. When the strip grinding belt 42 of the grinding part needs to be replaced, the part of the strip grinding belt 42 at the end of the fixed column 41 and the outside of the triangular block 411 can be changed by rewinding and unwinding the two reeling wheels 31.

[0044] like Figure 7 As shown, a gas guide assembly 43 is sleeved on the outer side of the fixed column 41, and the gas guide assembly 43 includes a fixed circular block 431 and a guide circular ring block 432 fixedly installed on the side of the fixed circular block 431 facing the hollow basin body 7. The fixed circular block 431 and the guide circular ring block 432 are hollow inside, and the hollow parts inside the two are connected. An air pump 34 is fixedly installed above the telescopic assembly 33, and the air pump 34 is connected to the fixed circular block 431 through an air pipe.

[0045] The hollow interior of the guide ring block 432 is specifically a ring-shaped air outlet structure, and the guide ring block 432 blows air in a ring shape toward the hollow basin body 7.

[0046] Specifically, when the strip sanding belt 42 is grinding the inside of the hollow basin 7, the gas guide assembly 43 is on the outside of the hollow basin 7. At this time, it is driven by the air pump 34, so that the gas is transported to the inside of the fixed circular block 431 and the guide circular ring block 432 through the pipeline. The guide circular ring block 432 then blows annular air toward the hollow basin 7. At this time, the relatively light annular wind can prevent a small amount of debris from being thrown toward the grinding assembly 4 due to centrifugal force, so that the debris is discharged from multiple strip discharge troughs 61, thereby protecting the strip sanding belt 42 outside the grinding assembly 4.

[0047] Example 2: Figure 8-9 As shown, in contrast to Example 1, another embodiment of the present invention is: a collecting box 8 is fixedly installed on the side of the driving component 5, the collecting box 8 covers the outside of the component cylinder 6, and an exhaust pipe 9 is fixedly installed on the outside of the collecting box 8, and the end of the exhaust pipe 9 is connected to the external suction equipment.

[0048] A through circular groove 81 is opened inside the collecting box body 8, and the component cylinder 6 is movably installed inside the through circular groove 81. Rectangular connecting grooves 82 are opened on both sides of the inside of the collecting box body 8. The rectangular connecting groove 82 is connected to the through circular groove 81, and the height of the rectangular connecting groove 82 is lower than the diameter of the through circular groove 81.

[0049] Specifically, the outer side of the component cylinder 6 is covered with a collection box 8, and the component cylinder 6 and the hollow basin body 7 rotate inside the collection box 8. When the strip discharge trough 61 discharges materials and the strip discharge trough 61 is inside the rectangular connecting groove 82, the discharged debris will be collected inside the rectangular connecting groove 82. With the operation of the external suction equipment, the debris collected inside the rectangular connecting groove 82 is transported from the exhaust pipe 9 to the centralized processing position, avoiding the thrown debris from affecting the surrounding working environment and speeding up the discharge speed of the debris. When the strip discharge trough 61 rotates to the vertical position passing through the circular groove 81, the distance between the outer side of the strip discharge trough 61 and the inner wall of the circular groove 81 is too small, which is not convenient for the discharge of the strip discharge trough 61. Due to the uniform distribution of multiple strip discharge grooves 61, that is, at this time, two strip discharge grooves 61 are in the rectangular connecting groove 82 for discharging, and the two strip discharge grooves 61 are in a vertical position that passes through the circular groove 81 and are not convenient for discharging. The suction force generated by the exhaust pipe 9 can only act on the two strip discharge grooves 61 in the rectangular connecting groove 82. At this time, the suction force for these two strip discharge grooves 61 is much greater than that for the other two strip discharge grooves 61, that is, when the component cylinder 6 rotates, the suction force generated by the external suction equipment is variable for the multiple strip discharge grooves 61. By periodically changing the size of the suction force, debris can be prevented from continuously accumulating in the hollow slot holes of the hollow basin body 7, thereby avoiding blockage and further accelerating the collection and cleaning of debris.

[0050] Working principle: When it is necessary to grind the inner surface of the hollow basin body 7, the hollow basin body 7 is first placed inside the component tube 6 and locked tightly. At this time, there is a gap between the vertical surface of the hollow basin body 7 inside the component tube 6 and the inner wall of the component tube 6. At this time, when the driving component 5 is driven, the component tube 6 connected to the driving component 5 through the shaft will rotate at high speed. At this time, the grinding component 4 is driven by the working platform 3 to perform multi-axis movement, so that the end grinding part of the grinding component 4 contacts the center position of the hollow basin body 7, and then performs horizontal displacement. In this process, the grinding part of the grinding component 4 contacts the inner surface of the high-speed rotating hollow basin body 7, and the contact part is ground. As the hollow basin body 7 continues to rotate, the working platform 3 drives the grinding component 4 to move along the center of the hollow basin body 7. The component 4 gradually moves away from the hollow basin body 7, and at this time the grinding part of the grinding component 4 contacts the inner surface of the circular ring of the hollow basin body 7, and then grinds it. Due to the hollow setting of the hollow basin body 7, a plurality of slots are opened inside it. The debris generated during the grinding process may be blocked or attached to the hollow slots of the hollow basin body 7, which requires additional cleaning after the hollow basin body 7 completes the grinding work. At this time, a plurality of strip discharge grooves 61 are opened inside the component cylinder 6. When the inner surface of the hollow basin body 7 is ground, the component cylinder 6 and the hollow basin body 7 rotate at a high speed, thereby generating centrifugal force so that the debris will pass through the hollow slots of the hollow basin body 7 into the gap between the hollow basin body 7 and the component cylinder 6 until the debris passes through the plurality of strip discharge grooves 61. The grinding debris will be thrown to the outside world. In this device, a plurality of arc-shaped guide grooves 62 are further provided inside the component cylinder 6. The two ends of the arc-shaped guide grooves 62 are connected to the two adjacent strip-shaped discharge grooves 61, and the distance between the inner wall of one end of the arc-shaped guide groove 62 and the center of the component cylinder 6 is smaller than the distance between the inner wall of the other end of the arc-shaped guide groove 62 and the center of the component cylinder 6. The distance between the inner wall of the arc-shaped guide groove 62 and the center of the component cylinder 6 is gradual. As the centrifugal force of the component cylinder 6 and the hollow basin 7 rotates, the grinding debris will be thrown to the inner wall of the component cylinder 6, that is, thrown into the inside of the arc-shaped guide groove 62. Due to the gradual setting of the distance between the inner wall of the arc-shaped guide groove 62 and the middle of the component cylinder 6, the grinding debris will be better moved from the arc-shaped guide groove 62 until the debris moves to the space between the arc-shaped guide groove 62 and the center of the component cylinder 6. The end with a larger distance therefrom is discharged from the strip discharge trough 61 connected to the end of the arc guide groove 62, so that the debris generated by grinding will not adhere to and clog the inner surface of the hollow basin body 7, thereby avoiding subsequent cleaning steps. The gradual change direction of the arc guide groove 62 from the center distance of the component cylinder 6 to the larger direction is consistent with the rotation direction of the component cylinder 6. The outside of the component cylinder 6 is covered with a collection box 8, and the component cylinder 6 and the hollow basin body 7 rotate inside the collection box 8. When the strip discharge trough 61 is discharged and the strip discharge trough 61 is inside the rectangular connecting groove 82, the discharged debris will be collected inside the rectangular connecting groove 82. With the operation of the external suction equipment, the debris collected inside the rectangular connecting groove 82 is transported from the exhaust pipe 9 to the centralized processing position.To avoid the thrown debris affecting the surrounding working environment and to speed up the discharge speed of the debris, when the strip discharge trough 61 rotates to the vertical position through the circular groove 81, the distance between the outer side of the strip discharge trough 61 and the inner wall of the circular groove 81 is too small, which is not convenient for the discharge of the strip discharge trough 61. Due to the uniform distribution of multiple strip discharge troughs 61, that is, at this time, two strip discharge troughs 61 are in the rectangular connecting groove 82 for internal discharge, and the two strip discharge troughs 61 are in the vertical position through the circular groove 81, which is not convenient for discharge. The suction force generated by the air pipe 9 can only act on the two strip discharge grooves 61 inside the rectangular connecting groove 82. At this time, the suction force on these two strip discharge grooves 61 is much greater than that on the other two strip discharge grooves 61. That is, when the component cylinder 6 rotates, the suction force generated by the external suction device on the multiple strip discharge grooves 61 is variable. By periodically changing the magnitude of the suction force, it is possible to prevent debris from continuously accumulating in the hollow slots of the hollow basin body 7, thereby avoiding blockage and further accelerating the collection and removal of debris.
